Description

托板夾 pallet clip

本發明所揭示之技術係關於一種托板夾(pallet clamp)。 The technology disclosed in the present invention relates to a pallet clamp.

將安裝有加工對象即工件的托板定位於加工機床之台面上，托板夾係於此狀態下對托板加以固定之裝置(機構)。專利文獻1及專利文獻2係揭示習知之托板夾。 A device (mechanism) that fixes the pallet with the processing object, that is, the workpiece, positioned on the table of the processing machine tool, and the pallet clamp is in this state. Patent Document 1 and Patent Document 2 disclose known pallet clamps.

專利文獻1中揭示一種托板夾，係透過將設於台面上的複數個定位銷***形成於托板之複數個定位孔內，加以定位。 Patent Document 1 discloses a pallet clamp, which is positioned by inserting a plurality of positioning pins arranged on the table into a plurality of positioning holes formed in the pallet.

專利文獻2中揭示一種托板夾，係用筒夾(collet)將托板拉至台面而加以固定。該托板夾中，於台面的複數位置處設有圓筒狀活塞銷，該活塞銷不僅收容筒夾，還在頂端部分具有漸縮之錐形面。於台面上與此等活塞銷中一一對應之複數位置處，設有拉桿螺栓及具有在其周圍延展之錐形承受面的支座。 Patent Document 2 discloses a pallet clamp, which uses a collet to pull the pallet to the table and fix it. In the pallet clamp, cylindrical piston pins are arranged at multiple positions on the table surface, and the piston pin not only accommodates the collet, but also has tapered tapered surfaces at the top end. At a plurality of positions corresponding to the piston pins on the table, tie rod bolts and supports with tapered bearing surfaces extending around them are provided.

托板夾夾持時，各錐形面與各錐形承受面嵌合，藉此將托板定位於台面。並且，透過筒夾夾住拉桿螺栓並向台面側拉動來將托板固定於台面。 When the pallet holder is clamped, each tapered surface fits with each tapered receiving surface, thereby positioning the pallet on the table. In addition, the tie rod bolt is clamped by the collet and pulled to the side of the table to fix the supporting plate on the table.

[先前技術文獻] [Prior Art Literature]

[專利文獻] [Patent Document]

專利文獻1：日本特開2003-170329號公報。 Patent Document 1: Japanese Unexamined Patent Publication No. 2003-170329.

專利文獻2：日本特開2005-81480號公報。 Patent Document 2: Japanese Unexamined Patent Publication No. 2005-81480.

於專利文獻1的托板夾之情形，雖然構造簡單，但定位孔與定位銷之間必然存在嵌合間隙，因此定位精度存在問題。 In the case of the pallet clamp of Patent Document 1, although the structure is simple, there is a gap between the positioning hole and the positioning pin. There is bound to be a fitting gap, so there is a problem with positioning accuracy.

在該點上，專利文獻2的托板夾利用錐形面與錐形承受面之嵌合來定位，因此乍看之下定位精度似乎優於專利文獻1的托板夾。 In this regard, the pallet clamp of Patent Document 2 is positioned by fitting the tapered surface and the tapered receiving surface, so the positioning accuracy seems to be better than that of the pallet clamp of Patent Document 1 at first glance.

然而，因為專利文獻2的托板夾的錐形部分係滑動構造，所以滑動導向部分必然存在間隙。因此，專利文獻2的托板夾的定位精度也存在問題。 However, since the tapered portion of the pallet clamp of Patent Document 2 is a sliding structure, there must be a gap in the sliding guide portion. Therefore, the positioning accuracy of the pallet clamp of Patent Document 2 also has a problem.

而且，於專利文獻2的托板夾之情形，構造上需要確保台面與托板之間有較大空間。相對於此，因為台面上方為加工工件的作業區域，所以需要將托板佈置得較低來確保有較大的作業區域。因此，於專利文獻2的托板夾之情形，存在作業區域狹小之嚴重問題。 Moreover, in the case of the pallet clamp of Patent Document 2, it is necessary to ensure a large space between the table top and the pallet in structure. In contrast, since the work area above the table is the work area for processing workpieces, it is necessary to arrange the pallet lower to ensure a larger work area. Therefore, in the case of the pallet clamp of Patent Document 2, there is a serious problem that the working area is narrow.

針對此等問題，本申請發明人著眼於使用狀態完全相異的夾盤(一邊高速旋轉一邊固定待加工之工件的裝置)。並且，經過反覆深入研究，發現透過將可提高夾盤的頂爪的安裝再現精度之技術應用於托板夾，便可解決此等問題，從而實現了一種優異的托板夾。 To solve these problems, the inventors of the present application focused their attention on chucks (devices that fix workpieces to be processed while rotating at high speeds) that are used in completely different states. In addition, after repeated in-depth research, it was found that by applying the technology that can improve the accuracy of installation and reproduction of the top jaw of the chuck to the pallet clamp, these problems can be solved, thereby realizing an excellent pallet clamp.

亦即，本發明所揭示之技術的目的在於，提供一種托板夾，不僅係可將托板佈置得較低之簡單、緊湊構造，而且可實現高精度定位及牢固固定。 That is, the object of the technique disclosed in the present invention is to provide a pallet clamp which not only has a simple and compact structure in which the pallet can be arranged lower, but also can realize high-precision positioning and firm fixing.

以下根據圖式詳細說明本發明所揭示之技術的實施形態。不過，以下說明僅為本質上的示例，並不對本發明、其應用對象或其用途做出限定。 Embodiments of the technology disclosed in the present invention will be described in detail below with reference to the drawings. However, the following The description is merely an example in nature and does not limit the invention, its object of application or its use.

(托板夾的整體構造) (The overall structure of the pallet clamp)

圖1係例示應用了本發明所揭示之技術的托板夾100A。托板夾100A係用於加工機床200(例如加工中心機(machining center))。 FIG. 1 illustrates a pallet clamp 100A to which the technology disclosed in the present invention is applied. The pallet holder 100A is used in a processing machine tool 200 (such as a machining center).

加工機床200具有沿大致水平方向延伸的台面(table)201，其上方為進行機械加工的作業區域。進行機械加工之前，將安裝有工件W的板狀托板300佈置於台面201上。 The processing machine tool 200 has a table 201 extending in a substantially horizontal direction, above which is a working area for machining. Before machining, the plate-shaped pallet 300 on which the workpiece W is mounted is placed on the table 201 .

為了以高精度定位之狀態將該托板300固定於台面201上，在托板300與台面201之間設有托板夾100A。托板夾100A的設置數量及佈置方式係能夠對應托板300的大小及形狀適當地選擇。例如，若托板300較小，則托板夾100A可為一個。本實施形態中，示例出四個托板夾100A設於台面201上保持有距離的四個位置處之情形。 In order to fix the pallet 300 on the table top 201 in a state of positioning with high precision, a pallet clamp 100A is provided between the pallet 300 and the table top 201 . The number and arrangement of the pallet clamps 100A can be appropriately selected according to the size and shape of the pallet 300 . For example, if the pallet 300 is small, there may be one pallet holder 100A. In this embodiment, the case where four pallet holders 100A are provided at four positions with distances on the table top 201 is exemplified.

本發明所揭示之托板夾100A的構造較習知托板夾簡單、緊湊。因此，部件成本也較低。並且，可將托板300佈置得比習知技術中更低。而且，靠簡單的操作即能夠實現托板300的高精度定位及牢固固定。 The pallet clamp 100A disclosed by the present invention has a simpler and more compact structure than conventional pallet clamps. Therefore, the component cost is also lower. Also, the pallet 300 can be arranged lower than in the prior art. Moreover, high-precision positioning and firm fixing of the pallet 300 can be realized by simple operations.

具體而言，托板夾100A中應用了夾盤的定位機構常用之「鋸齒(鋸齒狀的嚙合構造)」。 Specifically, "sawtooth (serrated meshing structure)" which is commonly used as a chuck positioning mechanism is applied to the pallet clamp 100A.

(托板夾100A之構造) (Structure of pallet holder 100A)

(第一實施形態) (first embodiment)

圖2中係放大顯示一托板夾100A。圖3中係顯示該托板夾100A之剖視圖。 A pallet holder 100A is shown enlarged in FIG. 2 . FIG. 3 shows a cross-sectional view of the pallet holder 100A.

托板夾100A的基本構成係具有夾持承受部110、夾持部130以及施力手段150。夾持承受部110設在托板300的背面。夾持部130設在台面201的設置面201a。施力手段150沿垂直於設置面201a之方向壓接夾持承受部110與夾持部130。本實施形態之托板夾100A還具有鍵部件170。鍵部件170存在於夾持承受部110與夾持部130之間。 The pallet clamp 100A basically includes a clamping receiving part 110 , a clamping part 130 , and a urging means 150 . The clamping receiving portion 110 is disposed on the back of the pallet 300 . The clamping part 130 is provided on the installation surface 201 a of the table top 201 . The force applying means 150 crimps the clamping receiving portion 110 and the mounting surface 201a in a direction perpendicular to clamping portion 130 . The pallet clamp 100A of this embodiment further has a key member 170 . The key member 170 exists between the clamp receiving part 110 and the clamp part 130 .

(夾持承受部110) (Clamp receiving part 110)

夾持承受部110由厚度較大的矩形板狀(長方體狀)金屬塊構成。夾持承受部110所具有的兩個板面中，一個板面(安裝面110a)一側固定於托板300的背面。藉此，夾持承受部110之面向托板300下方的另一個板面一側構成壓接於夾持部130的壓接部位。於該壓接部位形成有被抵接面111，於該被抵接面111形成有鋸齒111a。 The clamping receiving part 110 is composed of a thick rectangular plate-shaped (cuboid-shaped) metal block. Among the two board surfaces of the clamp receiving part 110 , one side (the installation surface 110 a ) is fixed to the back surface of the pallet 300 . In this way, the side of the clamping receiving portion 110 facing the lower side of the other plate surface of the supporting plate 300 constitutes a crimping portion that is crimped to the clamping portion 130 . A contacted surface 111 is formed at the crimping portion, and serrations 111 a are formed on the contacted surface 111 .

具體而言，鋸齒111a係公知的鋸齒狀嚙合構造。鋸齒111a由一組線狀凸部及線狀凹部構成，該一組線狀凸部及線狀凹部係由橫截面形狀為近似三角形之凹凸連接起來而構成。此等構造的鋸齒111a以橫截面形狀沿被抵接面111的寬度方向(短邊側的方向)延伸之方式形成於被抵接面111上。以下，也將鋸齒沿寬度方向延伸的方向稱為「鋸齒延伸方向」。 Specifically, the sawtooth 111a is a known sawtooth meshing structure. The sawtooth 111a is composed of a set of linear protrusions and linear recesses, and the set of linear protrusions and linear recesses are formed by connecting concavities and protrusions whose cross-sectional shapes are approximately triangular. The serrations 111 a having such a structure are formed on the contacted surface 111 so that the cross-sectional shape extends in the width direction (the direction of the short sides) of the contacted surface 111 . Hereinafter, the direction in which the sawtooth extends along the width direction is also referred to as the "sawtooth extending direction".

於被抵接面111的寬度方向的中央部位，以橫向截斷鋸齒111a之方式形成有鍵槽112。鍵槽112係橫截面為矩形的槽。鍵槽112沿被抵接面111的長度方向(長邊側的方向)延伸，並貫穿夾持承受部110的兩端。藉此被抵接面111被鍵槽112一分為二。於鍵槽112兩側形成有一對鋸齒111a的帶狀區域。 A key groove 112 is formed at the central portion in the width direction of the contacted surface 111 so as to transversely cut off the serrations 111 a. The keyway 112 is a groove with a rectangular cross section. The key groove 112 extends along the length direction (long side direction) of the abutted surface 111 and penetrates both ends of the clamp receiving portion 110 . As a result, the abutted surface 111 is divided into two by the key groove 112 . A pair of sawtooth 111 a band-shaped regions are formed on both sides of the keyway 112 .

具體而言，鍵槽112形成為沿鋸齒111a凹凸之排列方向延伸。在鍵槽112的大致中央部位(夾持承受部110的大致中央部位)形成有貫穿安裝面110a的螺栓孔113。 Specifically, the key groove 112 is formed to extend along the direction in which the concavities and convexities of the serrations 111a are arranged. A bolt hole 113 penetrating through the attachment surface 110 a is formed in an approximately central portion of the key groove 112 (approximately central portion of the clamp receiving portion 110 ).

(夾持部130) (clamping part 130)

各夾持部130以與佈置於托板300各處的各夾持承受部110相向之方式佈置於台面201各處。 Each clamping portion 130 is disposed on the table top 201 so as to face each clamping receiving portion 110 disposed on the pallet 300 .

夾持部130也由厚度較大的矩形板狀金屬塊構成。夾持部130的兩個板面中，一個板面(安裝面130a)側固定於台面201的設置面201a。具體而言，利用螺栓131(本實施形態中為兩個)將夾持部130緊固於台面201。夾持部130之面向台面201上方的另一個板面側構成壓接於夾持承受部110的壓接部位。於該壓接部位形成有抵接面132，該抵接面132上形成有鋸齒132a。 The clamping portion 130 is also composed of a thicker rectangular plate-shaped metal block. The two plates of the clamping part 130 Among the surfaces, one plate surface (installation surface 130 a ) side is fixed to the installation surface 201 a of the table top 201 . Specifically, the clamping portion 130 is fastened to the table top 201 with bolts 131 (two in the present embodiment). The other side of the clamping portion 130 facing above the table surface 201 constitutes a crimping portion that is crimped to the clamping receiving portion 110 . An abutting surface 132 is formed at the crimping portion, and serrations 132 a are formed on the abutting surface 132 .

具體而言，與被抵接面111緊密接觸的鋸齒132a以沿抵接面132的寬度方向(短邊側的方向)延伸之方式形成於抵接面132上。 Specifically, the serrations 132 a that are in close contact with the contacted surface 111 are formed on the contact surface 132 so as to extend in the width direction (direction of the short sides) of the contact surface 132 .

在抵接面132的寬度方向的中央部位，以橫向截斷鋸齒132a之方式形成有支承槽133。支承槽133係橫截面為矩形的槽。支承槽133沿抵接面132的長度方向(長邊側的方向)延伸，並貫穿夾持部130的兩端。藉此，抵接面132被支承槽133一分為二。於支承槽133的兩側形成有一對鋸齒132a的帶狀區域。 A support groove 133 is formed at the central portion of the contact surface 132 in the width direction so as to cut the serrations 132a laterally. The support groove 133 is a groove with a rectangular cross section. The support groove 133 extends along the lengthwise direction (direction of the long sides) of the abutting surface 132 and penetrates both ends of the clamping portion 130 . Thereby, the abutting surface 132 is divided into two by the supporting groove 133 . A pair of sawtooth 132 a strip-shaped regions are formed on both sides of the support groove 133 .

具體而言，與鍵槽112一樣，支承槽133也沿鋸齒132a凹凸之排列方向延伸。因此，支承槽133構成為：當抵接面132與被抵接面111緊密接觸時，支承槽133與鍵槽112相向且與鍵槽112重合。於支承槽133的大致中央部位，形成有貫穿安裝面130a的緊固孔134(具有內螺紋的孔，以下相同)。 Specifically, like the keyway 112, the support groove 133 also extends along the direction in which the serrations 132a are arranged. Therefore, the supporting groove 133 is configured such that when the abutting surface 132 is in close contact with the abutted surface 111 , the supporting groove 133 faces the key groove 112 and overlaps with the key groove 112 . A fastening hole 134 (a hole having an internal thread, the same applies hereinafter) penetrating through the mounting surface 130 a is formed at a substantially central portion of the support groove 133 .

如圖4所示，於夾持部130的各側面上，形成有貫穿支承槽133之側面的橫螺紋孔135。各橫螺紋孔135佈置在支承槽133各端部之保持有距離的位置處。頂端為圓錐狀的鍵止動螺栓136分別擰入此等橫螺紋孔135中。鍵止動螺栓136的頂端以向支承槽133突出之方式構成。 As shown in FIG. 4 , on each side of the clamping portion 130 , a horizontal screw hole 135 penetrating through the side of the support groove 133 is formed. The transverse threaded holes 135 are arranged at distanced positions between the ends of the support grooves 133 . Key stopper bolts 136 with conical tips are screwed into these horizontal threaded holes 135, respectively. The tip of the key stopper bolt 136 is configured to protrude toward the support groove 133 .

(鍵部件170) (key part 170)

鍵部件170由一邊較長的金屬板狀部件構成。鍵部件170具有厚板狀的鍵部171及比鍵部171長的厚板狀支承部172。鍵部171以層疊於支承部172之長度方向大致中央部之方式與支承部172構成一體。鍵部171具有寬度小於鍵槽112的寬度的部分及寬度大於鍵槽112的寬度的部分。支承部172的寬度略小於支承槽133的寬度。於鍵部件170的大致中央，形成有沿厚度方向貫穿鍵部171及支承部172的通孔173。 The key member 170 is formed of a metal plate-shaped member with a long side. The key member 170 has a thick plate-shaped key portion 171 and a thick plate-shaped support portion 172 longer than the key portion 171 . The key portion 171 is integrally formed with the support portion 172 so as to be stacked on a substantially central portion in the longitudinal direction of the support portion 172 . The key portion 171 has a portion whose width is smaller than that of the key groove 112 and a portion whose width is larger than that of the key groove 112 . The width of the support portion 172 The width is slightly smaller than the width of the support groove 133. A through hole 173 penetrating through the key portion 171 and the support portion 172 in the thickness direction is formed substantially in the center of the key member 170 .

透過將鍵部171各側面的一部分削掉一定厚度而在各側面的對角位置形成有相對略突出的一對作用部174、174。 A pair of action portions 174 , 174 are formed at diagonally opposite positions on each side by cutting a part of each side of the key portion 171 to a certain thickness.

亦即，如圖4所示，包括一個作用部174的鍵部171各端部的寬度W1形成為小於鍵槽112的寬度W2，包括一對作用部174的鍵部171的最大寬度W3形成為略大於鍵槽112的寬度W2(W1<W2<W3)。其結果，鍵部171雖然無法傾斜著***鍵槽112中，但若傾斜即為可***之狀態(由於係微小之傾斜故省略圖示)。 That is, as shown in FIG. 4, the width W1 of each end portion of the key portion 171 including one action portion 174 is formed to be smaller than the width W2 of the key groove 112, and the maximum width W3 of the key portion 171 including a pair of action portions 174 is formed to be approximately It is larger than the width W2 of the key groove 112 (W1<W2<W3). As a result, although the key portion 171 cannot be inserted into the key groove 112 obliquely, it can be inserted if it is inclined (illustration is omitted because of a slight inclination).

於支承部172各側面的對角位置(與鍵部171的作用部174相同的對角位置)，形成有供鍵止動螺栓136的頂端嵌合的一對圓錐狀凹部175、175。 A pair of conical recesses 175 , 175 into which the tip of the key stopper bolt 136 fits is formed at diagonal positions on each side of the support portion 172 (the same diagonal position as the action portion 174 of the key portion 171 ).

如圖4所示，支承部172利用一對鍵止動螺栓136、136以無法脫出之狀態與支承槽133嵌合。於此狀態下，通孔173與緊固孔134重合。 As shown in FIG. 4 , the support portion 172 is fitted into the support groove 133 in a state where it cannot be removed by a pair of key stopper bolts 136 , 136 . In this state, the through hole 173 coincides with the fastening hole 134 .

(托板夾100A的安裝) (Installation of pallet clamp 100A)

以下說明利用此等托板夾100A將托板300安裝到台面201上的安裝作業。首先，放置托板300，保證各夾持承受部110重疊在被佈置於台面201上的各夾持部130。 Next, an installation operation of attaching the pallet 300 to the table top 201 using these pallet clamps 100A will be described. Firstly, place the pallet 300 to ensure that each clamping receiving portion 110 overlaps each clamping portion 130 arranged on the table 201 .

藉此，抵接面132之鋸齒111a與被抵接面111之鋸齒132a鬆嚙合，抵接面132與被抵接面111以該鬆嚙合狀態接觸，鍵部171進入鍵槽112內。此時，鍵部171與鍵槽112在寬度方向上留有間隙，鍵部171以此狀態嵌合在鍵槽112中。螺栓孔113與通孔173及緊固孔134重合。 Thereby, the serrations 111 a of the abutting surface 132 are loosely engaged with the serrations 132 a of the abutted surface 111 , the abutting surface 132 and the abutted surface 111 are in loose meshed contact, and the key portion 171 enters the key groove 112 . At this time, there is a gap between the key portion 171 and the key groove 112 in the width direction, and the key portion 171 is fitted into the key groove 112 in this state. The bolt hole 113 overlaps with the through hole 173 and the fastening hole 134 .

將緊固螺栓151***彼此重合的螺栓孔113及通孔173內，並將緊固螺栓151擰入緊固孔134。藉此沿垂直於設置面201a之方向將夾持承受部110與夾持部130壓接起來。亦即，該托板夾100A中，由緊固螺栓151構成施力手段 150。 The fastening bolts 151 are inserted into the overlapping bolt holes 113 and the through holes 173 , and the fastening bolts 151 are screwed into the fastening holes 134 . In this way, the clamping receiving part 110 and the clamping part 130 are crimped together in a direction perpendicular to the installation surface 201a. That is, in this pallet clamp 100A, the fastening bolt 151 constitutes the force applying means. 150.

若利用緊固螺栓151繼續壓接，則各鋸齒111a、132a會緊密嚙合，被抵接面111與抵接面132便會緊密接觸。如此，在鋸齒111a(132a)凹凸之排列方向(被抵接面111的長度方向)上，夾持承受部110高精度地定位於夾持部130且牢固地固定於夾持部130。 If the crimping is continued with the fastening bolt 151 , the serrations 111 a and 132 a will be closely engaged, and the abutted surface 111 and the abutting surface 132 will be in close contact. In this way, the clamping receiving part 110 is positioned on the clamping part 130 with high precision and firmly fixed to the clamping part 130 in the arrangement direction of the concavo-convex of the serrations 111a ( 132a ) (the length direction of the contacted surface 111 ).

並且，夾持承受部110與夾持部130平行，二者的寬度方向的中心線一致。此時，如上所述，鍵部171構成定位機構。因此，若抵接面132與被抵接面111緊密接觸，則如圖4的空心箭頭所示，鍵部171的一個作用部174與鍵槽112的一個側面接觸，鍵部171的另一個作用部174與鍵槽112的另一個側面接觸而進行推壓。 Moreover, the clamping receiving portion 110 is parallel to the clamping portion 130 , and the center lines in the width direction of the two coincide. At this time, as described above, the key portion 171 constitutes a positioning mechanism. Therefore, if the abutting surface 132 is in close contact with the abutted surface 111, as shown by the hollow arrow in FIG. 174 comes into contact with the other side of the key groove 112 to be pressed.

亦即，鍵部171的一個作用部174向外推壓鍵槽112的一個側面，鍵部171的另一個作用部174向外推壓鍵槽112的另一個側面。利用經支承部172固定於夾持部130之鍵部171，夾持承受部110被從其內側經由鍵槽112的兩側面朝著彼此相反的方向推壓。因此，於鋸齒111a的延伸方向(被抵接面111的寬度方向)，也能夠高精度定位且牢固固定。 That is, one action portion 174 of the key portion 171 pushes one side of the key groove 112 outward, and the other action portion 174 of the key portion 171 pushes the other side of the key groove 112 outward. With the key portion 171 fixed to the holding portion 130 via the support portion 172 , the holding receiving portion 110 is pushed in opposite directions from the inner side thereof via both side surfaces of the key groove 112 . Therefore, also in the extending direction of the sawtooth 111 a (the width direction of the contacted surface 111 ), it can be positioned with high precision and firmly fixed.

又，如後所述，該托板夾100A中，鍵槽112的一個側面相當於推壓面180，鍵槽112的另一個側面相當於反推壓面181。 In addition, as will be described later, in this pallet clamp 100A, one side of the key groove 112 corresponds to the pressing surface 180 , and the other side of the key groove 112 corresponds to the counter pressing surface 181 .

(第二實施形態) (Second Embodiment)

圖5係顯示本實施形態的托板夾100B之剖視圖。托板夾100B的基本構成與上述托板夾100A相同。因此，對於具有相同構造及功能的部件，用同一符號顯示而省略其說明，僅說明相異的內容(其他實施形態也同樣)。 FIG. 5 is a cross-sectional view showing the pallet holder 100B of this embodiment. The basic configuration of the pallet holder 100B is the same as that of the pallet holder 100A described above. Therefore, members having the same structure and function are shown with the same symbols, their descriptions are omitted, and only the different contents will be described (the same applies to other embodiments).

該托板夾100B中，對一個托板夾100B使用兩個鍵部件170。且構成為：一個鍵部件170推壓推壓面180，另一個鍵部件170推壓反推壓面181。 In this pallet holder 100B, two key members 170 are used for one pallet holder 100B. Furthermore, one key member 170 presses the pressing surface 180 , and the other key member 170 presses the counter pressing surface 181 .

各鍵部件170由縱橫寬度與支承槽133的寬度大致相同的長方體狀相同部件構成。該鍵部件170的鍵部171的一個側面(非作用部176)透過以一定厚度削掉該側面的一部分，而比另一個側面(作用部174)離鍵部171的寬度方向的中心側較近。藉此，構成為：嵌合於鍵槽112中以後，會在各鍵部件170與鍵槽112的側面之間形成間隙。 Each key member 170 is made of a rectangular parallelepiped whose vertical and horizontal widths are approximately the same as the width of the supporting groove 133. Component composition. One side (non-action portion 176) of the key portion 171 of the key member 170 is closer to the center side of the width direction of the key portion 171 than the other side (action portion 174) by shaving off a part of the side with a certain thickness. . Thereby, after being fitted into the key groove 112 , a gap is formed between each key member 170 and the side surface of the key groove 112 .

在鍵部件170的大致中央，形成有沿厚度方向貫穿鍵部171及支承部172的螺栓孔113。在夾持部130的支承槽133之緊固孔134的兩側對稱地形成有第二緊固孔134A。各鍵部件170的作用部174及非作用部176各自以相對於鍵槽112的各側面方向彼此相反之狀態，利用螺栓131緊固至第二緊固孔134A內，藉此固定於夾持部130。 A bolt hole 113 penetrating through the key portion 171 and the support portion 172 in the thickness direction is formed substantially in the center of the key member 170 . Second fastening holes 134A are symmetrically formed on both sides of the fastening hole 134 of the supporting groove 133 of the clamping portion 130 . The active portion 174 and the non-active portion 176 of each key member 170 are respectively fastened into the second fastening hole 134A with the bolt 131 in a state opposite to each other with respect to each side surface of the key groove 112 , thereby being fixed to the clamping portion 130 .

(托板夾100B的安裝) (Installation of pallet clamp 100B)

與第一實施形態一樣，將緊固螺栓151擰入彼此重合的螺栓孔113及緊固孔134內。若利用緊固螺栓151繼續壓接，則被抵接面111與抵接面132便會緊密接觸。如此，在鋸齒111a凹凸之排列方向上，夾持承受部110高精度地定位於夾持部130且牢固地固定於夾持部130。 As in the first embodiment, the fastening bolts 151 are screwed into the overlapping bolt holes 113 and fastening holes 134 . If the crimping is continued by the fastening bolt 151 , the contacted surface 111 and the contact surface 132 will be in close contact. In this way, in the arrangement direction of the concavo-convex of the serrations 111 a , the clamping receiving portion 110 is positioned on the clamping portion 130 with high precision and is firmly fixed to the clamping portion 130 .

除了有兩個鍵部件170這一點以外，其佈置及尺寸關係與鍵部171相同(參照圖6的W1、W2、W3)。因此，如圖6的空心箭頭所示，一個鍵部件170的作用部174與鍵槽112的一個側面接觸，另一個鍵部件170的作用部174與鍵槽112的另一個側面接觸而進行推壓。 Except for the fact that there are two key members 170, the arrangement and dimensional relationship are the same as those of the key portion 171 (see W1, W2, and W3 in FIG. 6). Therefore, as shown by the hollow arrows in FIG. 6 , the action portion 174 of one key member 170 is in contact with one side of the key groove 112 , and the action portion 174 of the other key member 170 is in contact with the other side of the key groove 112 to press.

藉此，於鋸齒111a的延伸方向上也能夠高精度定位且牢固固定。與第一實施形態一樣，該托板夾100B中亦為：鍵槽112的一個側面相當於推壓面180，鍵槽112的另一個側面相當於反推壓面181。 Thereby, it can also be positioned with high precision and firmly fixed in the extending direction of the sawtooth 111a. Similar to the first embodiment, in this pallet clamp 100B, one side of the key groove 112 corresponds to the pressing surface 180 , and the other side of the key groove 112 corresponds to the counter pressing surface 181 .

於該托板夾100B之情形，因為能夠使鍵部件170較小且簡單，還能夠同時使用兩個該鍵部件170，所以能夠實現比第一實施形態更簡單、更廉價。此外，因為可使推壓面180與反推壓面181之間的距離比第一實施形態中大，所以可以更高的精度定位且更牢固地固定。 In the case of the pallet holder 100B, since the key member 170 can be made small and simple, and two of the key members 170 can be used at the same time, it can be realized simpler and cheaper than the first embodiment. In addition, because the distance between the pressing surface 180 and the counter pressing surface 181 can be made larger than that of the first embodiment Medium and large, so it can be positioned with higher precision and fixed more firmly.

(第三實施形態) (third embodiment)

圖7係顯示本實施形態的托板夾100C之剖視圖。在該托板夾100C中做了改進，透過將夾盤構造應用於第二實施形態的托板夾100B，來提高鍵部件170的佈置自由度。 Fig. 7 is a sectional view showing the pallet holder 100C of this embodiment. This pallet clamp 100C is improved, and the degree of freedom in the arrangement of the key member 170 is increased by applying the chuck structure to the pallet clamp 100B of the second embodiment.

亦即，在夾持承受部110上，從鍵槽112到達安裝面110a的兩個螺栓孔113、113對稱地形成於鍵槽112的長度方向上保持有距離的位置處。並且，支承槽133由橫截面為近似倒T形的槽構成。具體而言，支承槽133具有口開在抵接面132上且寬度相對較窄的窄幅部133a及與窄幅部133a相連且寬度相對較寬的寬幅部133b。 That is, on the clamp receiving portion 110 , two bolt holes 113 , 113 reaching the mounting surface 110 a from the key groove 112 are symmetrically formed at positions keeping a distance in the length direction of the key groove 112 . Also, the support groove 133 is formed by a groove with a cross section approximately inverted T shape. Specifically, the support groove 133 has a relatively narrow narrow portion 133 a opening on the abutting surface 132 and a relatively wide width portion 133 b connected to the narrow portion 133 a and relatively wide.

各鍵部件170形成為橫截面近似T形。各鍵部件170具有以能夠相對於寬幅部133b滑動之狀態與寬幅部133b嵌合的防脫出部170a、以與窄幅部133a之間留有間隙的狀態與該窄幅部133a嵌合的中段部170b以及以與鍵槽112之間留有間隙的狀態與該鍵槽112嵌合的鍵部171。鍵部171的兩個側面中，一個側面(非作用部176)比另一個側面(作用部174)更靠近中心側，當與鍵槽112嵌合後，能夠在與鍵槽112的側面之間形成間隙，與第二實施形態相同。 Each key member 170 is formed in an approximately T-shape in cross section. Each key member 170 has a slip-off preventing portion 170a that fits into the wide portion 133b in a slidable state relative to the wide portion 133b, and fits into the narrow portion 133a with a gap between the narrow portion 133a. The key portion 171 is fitted into the key groove 112 with a gap between the middle portion 170 b and the key groove 112 . Of the two side surfaces of the key portion 171, one side (non-action portion 176) is closer to the center side than the other side (action portion 174), and when fitted into the key groove 112, a gap can be formed between the side surface of the key groove 112. , the same as the second embodiment.

於各鍵部件170的大致中央，形成有沿厚度方向貫穿鍵部171及支承部172的第三緊固孔134B。 A third fastening hole 134B penetrating through the key portion 171 and the support portion 172 in the thickness direction is formed substantially at the center of each key member 170 .

(托板夾100C的安裝) (Installation of pallet clamp 100C)

該托板夾100C中，各鍵部件170的作用部174及非作用部176各自以相對於鍵槽112的各側面方向彼此相反之狀態***支承槽133內。如此，各鍵部件170便被定位，夾持承受部110的兩個螺栓孔113與第三緊固孔134B彼此重合，將***各螺栓孔113的兩個緊固螺栓151分別擰入各第三緊固孔 134B中。 In this pallet clamp 100C, the active portion 174 and the non-active portion 176 of each key member 170 are inserted into the support groove 133 in a state in which the direction of each side surface of the key groove 112 is opposite to each other. In this way, each key member 170 is positioned, the two bolt holes 113 of the clamping receiving portion 110 overlap with the third fastening hole 134B, and the two fastening bolts 151 inserted into the bolt holes 113 are respectively screwed into the third fastening holes 134B. fastening hole 134B.

若利用此等緊固螺栓151繼續壓接，則被抵接面111與抵接面132便會緊密接觸。如此，在鋸齒111a凹凸之排列方向上，夾持承受部110高精度地定位於夾持部130且牢固地固定於夾持部130。 If the crimping is continued with these fastening bolts 151 , the abutted surface 111 and the abutting surface 132 will be in close contact. In this way, in the arrangement direction of the concavo-convex of the serrations 111 a , the clamping receiving portion 110 is positioned on the clamping portion 130 with high precision and is firmly fixed to the clamping portion 130 .

如圖7及圖8所示，該鍵部件170中，鍵槽112的寬度W4大於鍵部171的寬度W1a，中段部170b的寬度W1b略大於鍵槽112的寬度W4(W1a<W4<W1b)。因此，如圖8的空心箭頭所示，與第二實施形態一樣，一個鍵部件170的作用部174與鍵槽112的一個側面接觸，另一個鍵部件170的作用部174與鍵槽112的另一個側面接觸而進行推壓。藉此於鋸齒111a的延伸方向上也能夠高精度地定位且牢固地固定。 7 and 8, in the key member 170, the width W4 of the key groove 112 is greater than the width W1a of the key portion 171, and the width W1b of the middle portion 170b is slightly greater than the width W4 of the key groove 112 (W1a<W4<W1b). Therefore, as shown by the hollow arrow in FIG. 8, like the second embodiment, the action portion 174 of one key member 170 is in contact with one side of the key groove 112, and the action portion 174 of the other key member 170 is in contact with the other side of the key groove 112. push by contact. Thereby, also in the extending direction of the sawtooth 111a, it can position with high precision and it can be firmly fixed.

於該托板夾100C之情形，與第二實施形態一樣，能夠使鍵部件170較小且簡單，而且兩個該鍵部件170還能夠同時使用。因為能夠對應於螺栓孔113的位置移動鍵部件170，所以鍵部件170的佈置自由度提高。 In the case of the pallet holder 100C, as in the second embodiment, the key member 170 can be made small and simple, and two of the key members 170 can be used simultaneously. Since the key member 170 can be moved corresponding to the position of the bolt hole 113, the degree of freedom in arrangement of the key member 170 is improved.

(第四實施形態) (Fourth Embodiment)

圖9係顯示本實施形態的托板夾100D之剖視圖。在該托板夾100D中做了改進，省略鍵部件170，而使部件數量減少。 Fig. 9 is a sectional view showing the pallet clamp 100D of this embodiment. In this pallet clamp 100D, an improvement is made, and the key part 170 is omitted, thereby reducing the number of parts.

具體而言，夾持承受部110的被抵接面111之鍵槽112被省略，於被抵接面111之整個區域形成有鋸齒111a。鋸齒111a平行於夾持承受部110的短邊延伸。 Specifically, the key groove 112 of the abutted surface 111 of the clamp receiving portion 110 is omitted, and the serrations 111 a are formed on the entire area of the abutted surface 111 . The serrations 111 a extend parallel to the short sides of the clamp receiving portion 110 .

夾持部130的抵接面132之支承槽133也被省略，於抵接面132的整個區域形成有鋸齒132a。夾持部130的鋸齒132a平行於夾持部130的短邊延伸。並且，於夾持部130的該鋸齒132a凹凸之排列方向上保持有距離的對角位置處，設有一對限制部137、137。 The supporting groove 133 of the abutting surface 132 of the clamping portion 130 is also omitted, and the sawtooth 132 a is formed on the entire area of the abutting surface 132 . The serrations 132 a of the clamping portion 130 extend parallel to the short sides of the clamping portion 130 . Moreover, a pair of restricting portions 137 , 137 are provided at diagonal positions of the clamping portion 130 at which a distance is maintained in the arrangement direction of the serrations 132 a.

各限制部137由沿抵接面132的邊緣延伸的壁狀凸部構成。此等限制部 137構成為：當以不緊固之狀態將夾持承受部110安裝至夾持部130以後，此等限制部137使夾持承受部110相對於夾持部130略微傾斜。亦即，如圖9所示，夾持部130之不包括此等限制部137、137的寬度W5略小於夾持承受部110的寬度W6。 Each restricting portion 137 is constituted by a wall-shaped protrusion extending along the edge of the contact surface 132 . such restrictions 137 is configured such that when the clamping receiving part 110 is mounted to the clamping part 130 in an unfastened state, the restricting parts 137 make the clamping receiving part 110 slightly inclined relative to the clamping part 130 . That is, as shown in FIG. 9 , the width W5 of the clamping portion 130 excluding the limiting portions 137 , 137 is slightly smaller than the width W6 of the clamping receiving portion 110 .

(托板夾100D的安裝) (Installation of pallet clamp 100D)

該托板夾100D中，將***夾持承受部110的螺栓孔113內的緊固螺栓151擰入緊固孔134。若利用緊固螺栓151繼續壓接，則被抵接面111與抵接面132緊密接觸。如此，相對於夾持部130略微傾斜的夾持承受部110便與夾持部130平行，夾持承受部110之與一個限制部137相向的側面端部會推壓該限制部137的相向面(相當於推壓面180)，夾持承受部110之與另一個限制部137相向的側面端部會推壓該限制部137的相向面(相當於反推壓面181)。 In this pallet clamp 100D, the fastening bolts 151 inserted into the bolt holes 113 of the clamp receiving portion 110 are screwed into the fastening holes 134 . If the crimping is continued by the fastening bolt 151 , the abutted surface 111 and the abutting surface 132 will come into close contact. In this way, the clamping receiving portion 110 slightly inclined with respect to the clamping portion 130 is parallel to the clamping portion 130 , and the side end of the clamping receiving portion 110 facing a restricting portion 137 will push the opposing surface of the restricting portion 137 (corresponding to the pressing surface 180 ), and the side end portion of the clamp receiving portion 110 facing the other restricting portion 137 pushes the opposite surface of the restricting portion 137 (corresponding to the counter pressing surface 181 ).

藉此於該托板夾100D之情形，亦為：在鋸齒111a凹凸之排列方向及鋸齒111a凹凸之延伸方向這兩個方向上，夾持承受部110高精度地定位於夾持部130且牢固地固定於夾持部130。並且，於該托板夾100D之情形，具有構造極其簡單且部件數量極少之優點。又，亦可使限制部137等夾持部130的構造與夾持承受部110的構造相反。 Therefore, in the case of the pallet clamp 100D, the clamping receiving part 110 is positioned on the clamping part 130 with high precision in two directions, the direction in which the serrations 111a are concavo-convex and the direction in which the concavities and convexities of the serrations 111a extend. fixed to the clamping portion 130. And, in the case of the pallet clamp 100D, there is an advantage that the structure is extremely simple and the number of parts is extremely small. In addition, the structure of the clamping part 130 such as the restricting part 137 may be reversed to the structure of the clamping receiving part 110 .

具體而言，與第四實施形態一樣，夾持承受部110的被抵接面111之鍵槽112被省略，於被抵接面111的整個區域形成有鋸齒111a。於該托板夾100E之情形，夾持承受部110的鋸齒111a平行於夾持部130的短邊延伸。 Specifically, as in the fourth embodiment, the key groove 112 of the abutted surface 111 of the clamp receiving portion 110 is omitted, and the sawtooth 111 a is formed on the entire area of the abutted surface 111 . In the case of the pallet clamp 100E, the serrations 111 a of the clamping receiving portion 110 extend parallel to the short side of the clamping portion 130 .

並且，於被抵接面111係形成有壓接軸153及銷孔154。壓接軸153具有固定於夾持承受部110之基軸部153a、固定於基軸部153a之小直徑軸本體153b以及設在軸本體153b的頂端之大直徑軸頭部153c，壓接軸153從被抵接面111的大致中央垂直地突出。在軸頭部153c的靠軸本體153b一側形成有傾斜為圓錐狀的配合面153d。 Furthermore, a crimping shaft 153 and a pin hole 154 are formed on the contacted surface 111 . The crimp shaft 153 has The base shaft part 153a fixed on the clamping receiving part 110, the small-diameter shaft body 153b fixed on the base shaft part 153a, and the large-diameter shaft head part 153c arranged on the top end of the shaft body 153b, the crimping shaft 153 from the abutted surface 111 Roughly the center protrudes vertically. On the side of the shaft head 153c close to the shaft body 153b, a matching surface 153d inclined in a conical shape is formed.

銷孔154係由從被抵接面111垂直延伸的圓孔構成。銷孔154形成於鋸齒111a的凹凸排列方向且與壓接軸153保持有距離的位置處。 The pin hole 154 is formed of a circular hole vertically extending from the contacted surface 111 . The pin hole 154 is formed in the concavo-convex alignment direction of the serrations 111 a at a position keeping a distance from the crimping shaft 153 .

與第四實施形態一樣，夾持部130的抵接面132之支承槽133也被省略，於抵接面132的整個區域形成有鋸齒132a。夾持部130的鋸齒132a也平行於夾持部130的短邊延伸。並且，於該抵接面132上形成有與壓接軸153相向且供壓接軸153***的軸孔155及與銷孔154相向且供銷孔154***的限制銷156。 Similar to the fourth embodiment, the supporting groove 133 of the abutting surface 132 of the clamping portion 130 is also omitted, and the sawtooth 132 a is formed on the entire area of the abutting surface 132 . The serrations 132 a of the clamping portion 130 also extend parallel to the short sides of the clamping portion 130 . Further, a shaft hole 155 facing the crimping shaft 153 into which the crimping shaft 153 is inserted and a restricting pin 156 facing the pin hole 154 and into which the pin hole 154 is inserted are formed on the contact surface 132 .

限制銷156具有鋸齒132a延伸方向上較長之近似菱形的橫截面。軸孔155與壓接軸153(軸頭部153c)之間及銷孔154與限制銷156(長徑側)之間皆存在微小間隙(嵌合間隙)。 The restricting pin 156 has a substantially diamond-shaped cross-section that is longer in the extending direction of the serrations 132a. There are slight gaps (fitting gaps) between the shaft hole 155 and the crimping shaft 153 (shaft head portion 153 c ) and between the pin hole 154 and the restricting pin 156 (longer diameter side).

於夾持部130形成有從該夾持部130之側面通至軸孔155側面的第二橫螺紋孔153A。突端部分呈圓錐狀的拉入軸157擰入第二橫螺紋孔153A中。拉入軸157的突端部分以向軸孔155突出之方式構成。 A second horizontal threaded hole 153A leading from a side of the clamping portion 130 to a side of the shaft hole 155 is formed in the clamping portion 130 . The pull-in shaft 157 whose protruding end portion is conical is screwed into the second horizontal threaded hole 153A. The protruding end portion of the pull-in shaft 157 is configured to protrude toward the shaft hole 155 .

限制銷156之位於拉入軸157側的側面構成發揮定位作用的作用部174。具體而言，如圖11的雙點虛線框內所示，夾持部130的限制銷156之位於拉入軸157側的側面與夾持部130的軸孔155之位於拉入軸157相反側的壁面之間的距離W7略大於夾持承受部110的銷孔154之位於拉入軸157側的壁面與夾持承受部110的壓接軸153之軸頭部153c之位於拉入軸157相反側的側面之間的距離W8。 The side surface of the restriction pin 156 on the pull-in shaft 157 side constitutes an action portion 174 for positioning. Specifically, as shown in the two-dot dashed line frame in FIG. The distance W7 between the wall surfaces is slightly larger than that of the pin hole 154 of the clamping receiving part 110. The wall surface on the side of the pull-in shaft 157 is opposite to that of the shaft head 153c of the crimping shaft 153 of the clamping receiving part 110 located on the pull-in shaft 157. The distance W8 between the sides of the side.

該托板夾100E中，係由壓接軸153、軸孔155以及拉入軸157等構成施力手段150。 In this pallet clamp 100E, it is composed of a crimping shaft 153, a shaft hole 155, and a pull-in shaft 157. Force means 150.

(托板夾100E的安裝) (Installation of pallet clamp 100E)

如圖10所示，該托板夾100E中，將限制銷156***銷孔154，將壓接軸153***軸孔155，並使抵接面132與被抵接面111接觸。於此狀態下，擰入拉入軸157，使其突端部分向軸孔155突出。如此，拉入軸157的突端部分便與配合面153d配合，透過基於此等傾斜的滑動作用，壓接軸153便被拉入軸孔155內。其結果，抵接面132與被抵接面111緊密接觸。 As shown in FIG. 10 , in this pallet clamp 100E, the restricting pin 156 is inserted into the pin hole 154 , the crimping shaft 153 is inserted into the shaft hole 155 , and the abutting surface 132 is brought into contact with the abutted surface 111 . In this state, the pull-in shaft 157 is screwed in so that the protruding end thereof protrudes toward the shaft hole 155 . In this way, the protruding end portion of the pull-in shaft 157 cooperates with the mating surface 153d, and the crimping shaft 153 is pulled into the shaft hole 155 through the sliding action based on these inclinations. As a result, the abutting surface 132 is in close contact with the abutted surface 111 .

同時，由於被拉入軸157推壓，因此軸頭部153c的側面會推壓軸孔155的位於拉入軸157相反側的壁面(相當於推壓面180)。隨之，夾持承受部110會沿鋸齒111a延伸方向偏移，但銷孔154的壁面會與限制銷156的位於拉入軸157一側的側面(作用部174)接觸，限制銷156的側面朝著與壓接軸153相反的方向推壓銷孔154的壁面(相當於反推壓面181)。 Simultaneously, since it is pushed by the pull-in shaft 157 , the side surface of the shaft head portion 153 c pushes the wall surface (corresponding to the push surface 180 ) of the shaft hole 155 on the opposite side to the pull-in shaft 157 . Thereupon, the clamping receiving portion 110 will deviate along the extending direction of the sawtooth 111a, but the wall surface of the pin hole 154 will contact with the side surface (acting portion 174) on the pull-in shaft 157 side of the limiting pin 156, and the side surface of the limiting pin 156 will The wall surface of the pin hole 154 is pressed in a direction opposite to the crimping shaft 153 (corresponding to the reverse pressing surface 181 ).

藉此，於該托板夾100E之情形，亦為：在鋸齒111a凹凸之排列方向及鋸齒111a凹凸之延伸方向這兩個方向上，夾持承受部110被高精度地定位於夾持部130且牢固地固定於夾持部130。因為施力手段150安裝於托板夾100E，所以作為托板夾的壓接手段能夠採用螺栓緊固以外的方法，很容易實現自動化。 Therefore, in the case of the pallet clamp 100E, the clamping receiving part 110 is positioned on the clamping part 130 with high precision in two directions, the direction in which the serrations 111a are concavo-convex and the direction in which the concavities and convexities of the serrations 111a extend. And firmly fixed on the clamping portion 130 . Since the urging means 150 is attached to the pallet clamp 100E, methods other than bolt fastening can be used as the crimping means of the pallet clamp, and automation can be easily realized.

(其他實施形態) (Other implementation forms)

本發明所揭示之技術不限於上述實施形態，還包括除此之外的各種構成。例如，夾持部130及夾持承受部110等托板夾的形狀僅為一例。此等構成部件的形狀可對應規格適當地變更。上述實施形態中，顯示了手動夾持的托板夾，亦可變更緊固螺栓151及拉入軸157的構造，使托板夾自動夾持。 The technology disclosed in the present invention is not limited to the above-mentioned embodiments, but also includes various other configurations. For example, the shapes of pallet clamps such as the clamping portion 130 and the clamping receiving portion 110 are merely examples. The shapes of these components can be appropriately changed according to the specifications. In the above-mentioned embodiment, the pallet clamp that is manually clamped is shown, but the structure of the fastening bolt 151 and the pull-in shaft 157 can also be changed so that the pallet clamp can be clamped automatically.

可使鍵槽及支承槽中的至少一者傾斜。關鍵在於，利用鋸齒的緊密接觸來產生朝著彼此相反之方向推壓的作用即可。 At least one of the keyway and the support groove may be inclined. The key is to use the close contact of the sawtooth to produce a pushing effect in opposite directions.

施力手段不限於螺栓緊固。例如有：以利用流體壓力的活塞驅動來拉入，或用凸輪桿使凸輪旋轉來推壓，或利用彈簧彈性來施力，或從上方用某種方法按住托板等手段。 The force applying means is not limited to bolt fastening. For example, there are: pulling in with a piston driven by fluid pressure, or pushing a cam by rotating a cam with a cam lever, applying force by using spring elasticity, or pressing the pallet by some method from above.

此外，當有複數個例如四個托板夾時，不需要在四個上都設置施力手段，有一個即可。而且，四個托板夾可皆無施力手段，可設置推壓四個托板夾的中央附近的其他施力手段。 In addition, when there are a plurality of, for example, four pallet clamps, it is not necessary to provide force applying means on all four, and only one is sufficient. Moreover, none of the four pallet clamps may have any means for applying force, and other force applying means for pushing the vicinity of the center of the four pallet clamps may be provided.

可對應規格適當地組合上述各實施形態的推壓面及反推壓面。例如，能夠想到將圖9中兩個137中之一個137替換為圖10的銷孔154(或壓接軸153)等。 The pressing surface and the counter pressing surface of each of the above embodiments can be appropriately combined according to the specifications. For example, it is conceivable to replace one 137 of the two 137 in FIG. 9 with the pin hole 154 (or crimping shaft 153 ) in FIG. 10 , or the like.
