Description
本創作關於一種導引套管，尤指一種用於導引螺釘的套管。This creation is about a guide sleeve, especially a sleeve for guiding screws.
一般在使用螺釘固定物件的場合中(例如固定汽車零部件)，使用者可直接以手指扶持、定位螺絲並使用螺絲起子將螺釘旋緊，或是使用手持式自動鎖螺絲機(例如透過夾爪式螺釘抓取、自動真空吸釘管、磁性螺絲起子等方式)將螺釘旋緊。當操作空間不足時(例如因汽車零部件本身結構複雜而使其鎖固孔上方空間狹小，又或因汽車零部件固定處有其他零部件結構的干擾，使得手指難以扶持、定位螺釘，或鎖螺絲機機頭難以伸入)，旋鎖螺釘將變得十分困難。另外，有些螺絲起子具有磁性頭部，可僅以螺絲起子吸附螺釘並將螺釘旋緊。然而當螺釘重量較大，磁吸力不足以穩定吸附螺釘，使得在前述操作空間不足的情形中，旋鎖螺釘仍不容易。In general, when using screws to fix objects (such as fixing automobile parts), users can directly support and position the screws with their fingers, use a screwdriver to tighten the screws, or use a hand-held automatic locking screw machine (such as through clamps) Screw grip, automatic vacuum suction tube, magnetic screwdriver, etc.) to tighten the screw. When the operating space is insufficient (for example, the space above the locking hole is narrow due to the complex structure of the auto part itself, or because of the interference of other parts structure at the place where the auto part is fixed, making it difficult to hold the finger, positioning the screw, or the lock The screw machine head is difficult to reach), and the turn lock screw will become very difficult. In addition, some screwdrivers have magnetic heads, which can only be used to attract and tighten the screws. However, when the weight of the screw is large, the magnetic attraction force is not enough to stably attract the screw, so that in the case where the foregoing operation space is insufficient, the spin lock screw is still not easy.
鑑於先前技術中的問題，本創作之一目的在於提供一種螺釘導套管，可於狹小的操作空間內導引螺釘，以便於螺絲起子旋緊螺釘。In view of the problems in the prior art, one of the purposes of the present invention is to provide a screw guide sleeve that can guide screws in a narrow operating space so that the screwdriver can tighten the screws.

關於本創作之優點與精神可以藉由以下的實施方式及所附圖式得到進一步的瞭解。The advantages and spirit of this creation can be further understood by the following embodiments and the attached drawings.
請參閱圖1及圖2。根據本創作之一實施例之一螺釘導套管1用以導引一螺釘2 (繪示於圖2中)，螺釘導套管1包含一直筒段12、一擴口段14及一擴張段16。直筒段12沿一導引方向D1延伸。擴口段14於導引方向D1連接至直筒段12的一端122，作為螺釘導套管1的入口結構，其大致上呈喇叭狀結構(或謂V形開口結構)，具有孔徑漸縮的特徵，利於導引螺釘2進入螺釘導套管1中。直筒段12的孔徑12a略大於螺釘2的頭部22的外徑22a，以使螺釘2能平順於直筒段12中滑動。擴張段16自直筒段12的另一端124沿導引方向D1延伸，作為螺釘導套管1的出口結構，其孔徑16a大於直筒段12的孔徑12a，可提供螺釘2相對較大的活動空間，以便於旋鎖螺釘2。Please refer to FIG. 1 and FIG. 2. According to one embodiment of the present invention, a screw guide sleeve 1 is used to guide a screw 2 (shown in FIG. 2). The screw guide sleeve 1 includes a straight tube section 12, a flared section 14 and an expanded section. 16. The straight section 12 extends in a guiding direction D1. The flared section 14 is connected to one end 122 of the straight section 12 in the guiding direction D1. As the entrance structure of the screw guide sleeve 1, it is generally a trumpet-like structure (or V-shaped opening structure), and has a feature of gradually decreasing aperture. , It is convenient for the guide screw 2 to enter the screw guide sleeve 1. The diameter 12 a of the straight tube segment 12 is slightly larger than the outer diameter 22 a of the head 22 of the screw 2 so that the screw 2 can slide smoothly in the straight tube segment 12. The expansion section 16 extends from the other end 124 of the straight tube section 12 in the guiding direction D1. As the exit structure of the screw guide sleeve 1, its aperture 16a is larger than the hole diameter 12a of the straight tube section 12, which can provide a relatively large space for the movement of the screw 2. For easy turn-lock screw 2.
請參閱圖3。於使用時，例如於需使用螺釘2以將一汽車零部件3 (以單一實體簡化表示於圖中)固定至一支撐座4上之場合中，先將汽車零部件3置於支撐座4 (例如汽車結構框架)上，並使汽車零部件3的鎖固孔3a (例如通孔，其孔徑略大於螺釘2的螺紋部24的外徑24a)對齊支撐座4的鎖固孔4a (例如螺孔，其與螺釘2的螺紋部24匹配)。再將螺釘導套管1實質穩定放置於汽車零部件3上(例如以手抓持)，並使擴張段16對齊鎖固孔3a。接著再將螺釘2的螺紋部24朝向螺釘導套管1，以使螺釘2經由擴口段14進入螺釘導套管1；螺釘2再經由直筒段12 (在重力作用下)移動至擴張段16，以經由擴張段16進入鎖固孔3a。接著，使用者再以螺絲起子伸入螺釘導套管1，將螺釘2旋緊，移離螺釘導套管1，即可實現將汽車零部件3固定於支撐座4上的目的。See Figure 3. In use, for example, where the use of screws 2 is required to fix an automobile component 3 (simplified as a single entity shown in the figure) to a support base 4, first place the automotive component 3 on the support base 4 ( For example, the structural frame of an automobile), and align the locking hole 3a (for example, a through hole with a diameter slightly larger than the outer diameter 24a of the threaded portion 24 of the screw 2) of the automobile component 3 with the locking hole 4a (for example, a screw Hole, which matches the threaded portion 24 of the screw 2). Then, the screw guide sleeve 1 is substantially stably placed on the automobile component 3 (for example, held by a hand), and the expansion section 16 is aligned with the locking hole 3a. Then, the threaded portion 24 of the screw 2 is directed toward the screw guide sleeve 1 so that the screw 2 enters the screw guide sleeve 1 through the flared section 14; the screw 2 is then moved to the expansion section 16 through the straight section 12 (under the action of gravity). To enter the locking hole 3a through the expansion section 16. Then, the user uses a screwdriver to reach into the screw guide sleeve 1 and tighten the screw 2 and move away from the screw guide sleeve 1 to achieve the purpose of fixing the automobile component 3 on the support base 4.
於實際應用上，螺釘導套管1用以導引同一種類的螺釘2，螺釘2的尺寸實際上會有製造公差，故配合地設計螺釘導套管1的尺寸，可使螺釘導套管1能具有較窄的結構以適應狹小的操作空間(例如圖3中汽車零部件3中鎖固孔3a上方空間受限於其他物件3b、3c的結構拘束，例如汽車零部件3上的電子零件)，且仍能平順導引螺釘2。螺釘2各尺寸的製造公差可透過實施一般的抽樣檢驗而實現，其細節不另贅述。又，同一種類的螺釘亦可能可由多組模具製造，抽樣檢驗數據可合併分析，以使螺釘導套管1的尺寸設計可適用於多組模具製造的成品。In practice, the screw guide sleeve 1 is used to guide the same type of screw 2. The size of the screw 2 will actually have manufacturing tolerances. Therefore, the size of the screw guide sleeve 1 is designed to match the screw guide sleeve 1 Can have a narrower structure to accommodate a narrow operating space (for example, the space above the locking hole 3a in the auto part 3 in FIG. 3 is limited by the structural constraints of other objects 3b, 3c, such as the electronic parts on the auto part 3) , And can still guide the screw 2 smoothly. The manufacturing tolerances of each dimension of the screw 2 can be realized by performing general sampling inspection, and details thereof will not be repeated. In addition, screws of the same type may also be manufactured by multiple sets of molds, and the sampling inspection data may be combined and analyzed, so that the size design of the screw guide sleeve 1 can be applied to the finished products manufactured by multiple sets of molds.
原則上，螺釘2各尺寸的實際值會呈常態分布。例如，螺釘2具有一軸向2a (以鏈線表示於圖2中)，螺紋部24自頭部22的底面沿軸向2a延伸，頭部22的外徑22a (即頭部22垂直於軸向2a的尺寸，例如呈圓形的外徑)對應一外徑製造平均值及一外徑製造標準差，螺紋部24的長度24b (即自頭部22的底面至螺紋部24末端面的距離)對應一長度製造平均值及一長度製造標準差。於一實施例中，直筒段12的孔徑12a小於該外徑製造平均值加上5倍的外徑製造標準差；進一步的，直筒段12的孔徑12a大於該外徑製造平均值加上4倍的外徑製造標準差。於另一實施例中，直筒段12的孔徑12a大於該外徑製造平均值加上6倍的外徑製造標準差。於另一實施例中，螺釘2為M8螺釘，當4倍的外徑製造標準差小於0.15mm時，直筒段12的孔徑12a大於該外徑製造平均值加上0.15mm，且小於該外徑製造平均值加上0.20mm。In principle, the actual value of each dimension of the screw 2 will be normally distributed. For example, the screw 2 has an axial direction 2a (shown as a chain line in FIG. 2), the threaded portion 24 extends from the bottom surface of the head 22 in the axial direction 2a, and the outer diameter 22a of the head 22 (that is, the head 22 is perpendicular to the shaft Dimension 2a, such as a circular outer diameter) corresponds to an outer diameter manufacturing average and an outer diameter manufacturing standard deviation, and the length 24b of the threaded portion 24 (the distance from the bottom surface of the head portion 22 to the end surface of the threaded portion 24). ) Corresponds to a length manufacturing average and a length manufacturing standard deviation. In an embodiment, the hole diameter 12a of the straight tube segment 12 is smaller than the outer diameter manufacturing average plus 5 times the outer diameter manufacturing standard deviation; further, the hole diameter 12a of the straight tube segment 12 is larger than the outer diameter manufacturing average plus 4 times. Manufacturing standard deviation. In another embodiment, the diameter 12a of the straight tube segment 12 is greater than the outer diameter manufacturing average plus 6 times the outer diameter manufacturing standard deviation. In another embodiment, the screw 2 is an M8 screw. When the manufacturing standard deviation of 4 times the outer diameter is less than 0.15 mm, the diameter 12a of the straight section 12 is greater than the manufacturing average of the outer diameter plus 0.15 mm, and is smaller than the outer diameter. Manufacturing average plus 0.20mm.
於一實施例中，擴張段16的孔徑16a大於該外徑製造平均值；進一步的，擴張段16的孔徑16a大於該外徑製造平均值加上12倍的外徑製造標準差。於另一實施例中．擴張段16的孔徑16a大於該外徑製造平均值加上12倍的外徑製造標準差。於另一實施例中，螺釘2為M8螺釘，當4倍的外徑製造標準差小於0.15mm時，擴張段16的孔徑16a大於該外徑製造平均值加上0.45mm。此外，若鎖固孔3a上方空間容許，擴張段16的孔徑16a可盡量擴大，以消除或抑制旋鎖螺釘2時，螺釘2 (的頭部22)與螺釘導套管1間可能的結構干涉。In one embodiment, the hole diameter 16a of the expanded section 16 is larger than the outer diameter manufacturing average; further, the hole diameter 16a of the expanded section 16 is larger than the outer diameter manufactured average plus 12 times the outer diameter manufacturing standard deviation. In another embodiment. The hole diameter 16a of the expanded section 16 is larger than the outer diameter manufacturing average plus 12 times the outer diameter manufacturing standard deviation. In another embodiment, the screw 2 is an M8 screw. When the manufacturing standard deviation of the outer diameter of 4 times is less than 0.15 mm, the hole diameter 16a of the expansion section 16 is greater than the manufacturing average of the outer diameter plus 0.45 mm. In addition, if the space above the locking hole 3a is allowed, the aperture 16a of the expansion section 16 can be enlarged as much as possible to eliminate or suppress possible structural interference between the screw 2 (the head 22) and the screw guide sleeve 1 when the screw 2 is turned .
於前述各實施例中，可進一步限制螺釘導套管1應用於4倍的外徑製造標準差小於0.15mm的情形。In the foregoing embodiments, the application of the screw guide sleeve 1 to a case where the manufacturing standard deviation of the outer diameter of 4 times is less than 0.15 mm can be further restricted.
於一實施例中，擴張段16於導引方向D1上的長度16b小於該長度製造平均值，使得螺釘2的頭部22進入擴張段16前，螺釘2的螺紋部22已進入鎖固孔3a。進一步的，擴張段16的長度16b可設計為小於該長度製造平均值加上4倍的長度製造標準差並減去0.5倍的螺紋部的導程，故原則上於旋轉螺釘2半圈後，頭部22便可進入擴張段16。或是，將擴張段16的長度16b設計為小於該長度製造平均值加上4倍的長度製造標準差並減去該螺紋部的導程，使得於旋轉螺釘2一圈後，頭部22便可進入擴張段16。或是，將擴張段16的長度16b設計為小於該長度製造平均值加上4倍的長度製造標準差並減去2倍的螺紋部的導程，使得於旋轉螺釘2兩圈後，頭部22便可進入擴張段16。In an embodiment, the length 16b of the expansion segment 16 in the guiding direction D1 is smaller than the average value of the length, so that before the head 22 of the screw 2 enters the expansion segment 16, the threaded portion 22 of the screw 2 has entered the locking hole 3a. . Further, the length 16b of the expansion section 16 can be designed to be smaller than the average length of the length plus 4 times the standard deviation of the length and subtract 0.5 times the lead of the threaded portion. Therefore, in principle, after rotating the screw 2 and a half turns, The head 22 can then enter the expansion section 16. Or, the length 16b of the expansion section 16 is designed to be smaller than the length manufacturing average plus 4 times the length manufacturing standard deviation and subtracting the lead of the threaded portion, so that after turning the screw 2 one turn, the head 22 will Can enter the expansion section 16. Alternatively, the length 16b of the expansion section 16 is designed to be smaller than the average length of the length plus 4 times the standard deviation of the length and 2 times the lead of the threaded portion, so that after turning the screw 2 two times, the head 22 can enter the expansion section 16.
此外，於圖3所示之實施場合中，汽車零部件3的鎖固孔3a為通孔，支撐座4的鎖固孔4a為螺孔，但實作上不以此為限；例如，鎖固孔3a、4a可均為螺孔。又，當鎖固孔3a (例如通孔)的孔徑明顯大於螺紋部24的外徑24a時，於旋鎖螺釘2的過程中，鎖固孔3a對螺釘2 (的螺紋部24)產生的結構拘束可能不足，此時，前述關於擴張段16的長度設計可合併考慮鎖固孔3a的深度(即擴張段16的長度16b加上鎖固孔3a的深度小於該長度製造平均值)，使得在螺釘2的頭部22進入擴張段16前，螺釘2的螺紋部22已進入鎖固孔4a。其設計細節可直接參閱前文，不另贅另。In addition, in the implementation shown in FIG. 3, the locking hole 3a of the automobile component 3 is a through hole, and the locking hole 4a of the support base 4 is a screw hole, but it is not limited to this in practice; for example, a lock Both the solid holes 3a and 4a may be screw holes. In addition, when the diameter of the locking hole 3a (for example, the through hole) is significantly larger than the outer diameter 24a of the screw portion 24, the structure of the locking hole 3a to the screw 2 (the screw portion 24) during the process of turning the screw 2 The restraint may be insufficient. At this time, the length design of the expansion section 16 may be combined with the depth of the locking hole 3a (that is, the length 16b of the expansion section 16 plus the depth of the locking hole 3a is less than the average length), so that Before the head 22 of the screw 2 enters the expansion section 16, the threaded portion 22 of the screw 2 has entered the locking hole 4a. The design details can be referred directly to the previous article, without further ado.
此外，於實作上，螺釘導套管1的直筒段12的內壁126的硬度大於螺釘2的表面硬度，有助於延長螺釘導套管1的使用壽命；此可透過採用適合的材質製作螺釘導套管1或對直筒段12的內壁126進行適合表面處理，不另贅述。另外，螺釘導套管1其各段的截面(垂直於延伸方向D1)均為圓形，但實作上不以此為限，其各段的截面僅需能使螺釘2通過已足；例如螺釘2的頭部22為六角柱形，直筒段12的截面則可為六角形或大於此六角柱形之圓形。又，於實作上為減少螺釘導套管1與實施環境中其他物件(例如汽車零部件3本身結構、或鄰近汽車零部件3之其他零部件或汽車構件等)產生結構干涉，擴張段16可採破口結構設計。如圖4所示之螺釘導套管5，與螺釘導套管1結構相似，故原則上沿用螺釘導套管1之元件符號，關於螺釘導套管5之其他說明，可直接參閱螺釘導套管1及其變化例之相關說明，不另贅述。相較於螺釘導套管1的擴張段16呈直筒狀，其包含完整的圍壁，圖4所示之螺釘導套管2的擴張段17包含不完整的圍壁，其截面呈C形。如圖5所示，擴張段17的缺口可避免與螺釘導套管2實施環境中其他物件3d (以虛線示意繪示於圖5中)產生結構干涉；其中，螺絲2 (的頭部22)輪廓以虛線繪示於圖5中，此時的螺釘導套管5仍可有效導引螺絲2並提供旋鎖螺絲2的空間。In addition, in practice, the hardness of the inner wall 126 of the straight tube section 12 of the screw guide sleeve 1 is greater than the surface hardness of the screw 2, which helps to extend the service life of the screw guide sleeve 1; The screw guide sleeve 1 or the inner wall 126 of the straight tube section 12 is suitable for surface treatment, and is not described in detail. In addition, the section of the screw guide sleeve 1 (vertical to the extending direction D1) is circular, but it is not limited in practice. The section of each section only needs to pass the screw 2; for example, The head 22 of the screw 2 is a hexagonal column, and the cross section of the straight cylindrical section 12 may be a hexagon or a circle larger than the hexagonal column. In addition, in order to reduce the structural interference between the screw guide tube 1 and other objects in the implementation environment (such as the structure of the automobile component 3 itself, or other components or automobile components adjacent to the automobile component 3), the extension section 16 is expanded. Can be used to break the structure design. The screw guide bushing 5 shown in FIG. 4 is similar in structure to the screw guide bushing 1, so in principle the component symbols of the screw guide bushing 1 are used. For other descriptions of the screw guide bushing 5, please refer to the screw guide bushing directly. The description of the tube 1 and its modification will not be repeated here. Compared with the expanded section 16 of the screw guide sleeve 1, the expanded section 16 includes a complete surrounding wall. The expanded section 17 of the screw guide sleeve 2 shown in FIG. 4 includes an incomplete surrounding wall, and its cross section is C-shaped. As shown in FIG. 5, the gap of the expansion section 17 can avoid structural interference with other objects 3d (schematically shown in dashed lines in FIG. 5) in the implementation environment of the screw guide tube 2; among them, the screw 2 (the head 22) The outline is shown in FIG. 5 with a dashed line. At this time, the screw guide sleeve 5 can still effectively guide the screw 2 and provide space for the screw 2.
如前文說明，根據本創作的螺釘導套管可以廣泛應用於電子或者汽車零部件行業的常規螺釘裝配，尤其是在間隙小於0.8mm的狹小空間中進行螺釘旋鎖，且能最大限度的避讓周邊干涉器件或結構，同時能保證及時入孔，最大的限度的規避習知導套管對螺釘旋鎖的負面影響。在現有行業常用的標準解決方案中，真空吸釘管(其管壁厚度大於0.8mm)和開合式夾爪(其厚度大於1mm)不能用於小於0.8mm的應用場合，均難以應用於間隙小於0.8mm的狹小空間中。又，根據本創作的螺釘導套管的直筒段的孔徑可設計為大於外徑製造平均值加上6倍的外徑製造標準差，以最大限度的保證螺釘一次性進入鎖固孔(可為通孔或螺孔)。螺釘導套管的擴張段可以有效避免螺釘的頭部與螺釘導套結構干涉，避免傾斜旋鎖造成螺釘歪斜或滑牙、爛牙等情況。根據本創作的螺釘導套管可普遍適用於螺釘旋鎖應用，通過調節不同壓力值(氣壓)，螺釘導套管可以在螺釘旋緊前產生預壓緊的作用，省去預旋鎖、再次旋緊的繁瑣工序，也能有效避免無預壓產生的應力集中造成的旋鎖失效。螺釘導套管對螺釘的頭部形狀無特定要求，圓形、多邊形等對稱形狀均可實施。As explained above, the screw guide bushing based on this creation can be widely used in conventional screw assembly in the electronics or automotive parts industry, especially for screw-locking in narrow spaces with a clearance less than 0.8mm, and can avoid the surroundings to the greatest extent. Interfering with the device or structure, while ensuring timely access to the hole, the negative effects of the conventional guide bushing on the screw lock can be avoided to the greatest extent. In the standard solutions commonly used in the existing industry, the vacuum suction tube (the wall thickness of which is greater than 0.8mm) and the open-close clamping jaw (the thickness of which is greater than 1mm) cannot be used for applications less than 0.8mm, and it is difficult to apply the gap less In a small space of 0.8mm. In addition, the diameter of the straight section of the screw guide sleeve according to the original creation can be designed to be greater than the average value of the outer diameter manufacturing plus 6 times the outer diameter manufacturing standard deviation to maximize the guarantee that the screw enters the locking hole at one time (can be Through holes or screw holes). The expanded section of the screw guide sleeve can effectively prevent the head of the screw from interfering with the structure of the screw guide sleeve, and prevent the screw from skewing, slipping, or rotten teeth caused by tilting the lock. The screw guide sleeve according to this creation can be universally applicable to screw lock applications. By adjusting different pressure values (air pressure), the screw guide sleeve can have a pre-compression effect before the screw is tightened, eliminating the need for pre-locks and re-locking. The tedious process of screwing can also effectively avoid the failure of the screw lock caused by the stress concentration without preload. The screw guide sleeve has no specific requirements on the shape of the head of the screw, and symmetrical shapes such as circles and polygons can be implemented.
