Description
本創作係為一種滾珠螺桿,尤指一種內循環式滾珠螺桿。
This creation is a ball screw, especially an internal circulation ball screw.
按,線性元件(滾珠螺桿、線性滑軌)係工業上常用之傳動組件,其被大量地使用在各式機器中須進行線性運動的地方,用來移動工件、搬運貨物或排列工件…各式用途。由此不難發現線性元件在工業中扮演傳動相關的重要角色,以及其工作時需經常進行移動的作業特色。According to the linear components (ball screw, linear slide), the transmission components commonly used in the industry are used in a large number of places where linear motion is required in various machines to move workpieces, carry goods or arrange workpieces. . It is not difficult to find that linear components play an important role in the transmission industry in the industry, as well as the characteristics of the work that needs to be moved frequently during work.
請參閱圖十所示,係為一般習知常見的內循環式滾珠螺桿的螺帽(1)及迴流片(2)的組立之剖視圖,該螺帽(1)係具有一穿孔(11),於該穿孔(11)之內緣面設有螺旋狀之滾動溝(111),另該螺帽(1)之外緣面設有一安裝孔,該安裝孔係貫穿該螺帽(1)之壁面並且與該穿孔(11)及滾動溝(111)連通,該迴流片(2)係設有複數迴流道(21),當該迴流片(2)裝設於該安裝孔時,該迴流道(21)係與滾動溝(111)銜接,使兩相鄰的滾動溝(111)形成一封閉的路徑;但該安裝孔或迴流片(2)於加工時,可能因為加工有些許誤差、或有毛邊之因素造成迴流道(21)的兩端與滾動溝(111)銜接處有錯位產生(如圖之元件符號G所指的即為錯位間距),而因為迴流片(2)的壁面與安裝孔的內壁面皆為干涉配合,故並無法將迴流片(2)於安裝孔中做任意方向的調整而讓錯位間距(G)消失;是以,裝配迴流片(2)的人員只能使用代柄砂輪,以研磨方式來修整該錯位間距(G),但這會讓整個裝配時程拉長,相對造成製造成本的提高,且修整完後滾珠螺桿的品質也無法一致(因為每一位裝配人員所研磨出來的迴流道截面不可能一致,故有時因為研磨太多造成迴流道的壁面變薄,使滾動體一撞擊該壁面就破裂,而使滾珠螺桿壞損),也造成客戶抱怨率提升不少。再者,因為迴流道(21)與滾動溝(111)之間有錯位的問題,故當滾動體(未顯示)於循環時,會造成滾動體撞擊錯位處的問題產生,相對使得滾珠螺桿運行相當不順暢,且更有可能造成迴流片(2)遭滾動體撞擊而壞損,使得滾珠螺桿的使用壽命縮短不少。Referring to FIG. 10, it is a cross-sectional view showing the assembly of a nut (1) and a reflow sheet (2) of a conventionally known internal circulation type ball screw. The nut (1) has a perforation (11). a spiral rolling groove (111) is disposed on the inner edge surface of the through hole (11), and a mounting hole is formed on the outer edge surface of the nut (1), the mounting hole is through the wall surface of the nut (1) And communicating with the through hole (11) and the rolling groove (111), the reflowing piece (2) is provided with a plurality of return channels (21), and when the reflowing piece (2) is installed in the mounting hole, the return channel ( 21) is engaged with the rolling groove (111) to form a closed path between the two adjacent rolling grooves (111); however, the mounting hole or the reflowing piece (2) may be processed due to slight error or The burrs cause the misalignment between the two ends of the return channel (21) and the rolling groove (111) (as indicated by the symbol G in the figure), and because of the wall surface and installation of the reflow plate (2) Inner wall of the hole For the interference fit, it is impossible to adjust the reflowing piece (2) in any direction in the mounting hole to make the misalignment distance (G) disappear; therefore, the person who assembles the reflowing piece (2) can only use the handle grinding wheel to Grinding method to trim the misalignment spacing (G), but this will lengthen the entire assembly time, which will result in an increase in manufacturing cost, and the quality of the ball screw will not be uniform after trimming (because each assembler grinds out The cross-section of the return channel is not uniform, so sometimes the wall surface of the return flow is thinned due to too much grinding, and the rolling element is broken when it hits the wall surface, and the ball screw is broken, which also causes a large increase in customer complaint rate. Moreover, because of the problem of misalignment between the return passage (21) and the rolling groove (111), when the rolling body (not shown) is circulated, the problem that the rolling element hits the misalignment occurs, and the ball screw is operated relatively. It is quite unsmooth and is more likely to cause the reflowing sheet (2) to be damaged by the impact of the rolling elements, which shortens the service life of the ball screw.
綜上所述,此種習用技術仍有改良精進之必要。In summary, this kind of conventional technology is still necessary for improvement and improvement.

In the embodiment, the fixing members (42) are respectively disposed on two sides of the sliding portion (412), and the two The second sliding track (422) is respectively engaged with the two first sliding paths (4121) of the sliding portion (412), so that the returning body (41) can slide relative to the two fixing members (42), The first sliding path (4121) and the second sliding path (422) are structures with concave-convex fit, for example, a fit of the dovetail groove and the dovetail block;
請參閱第四圖所示,而該迴流模組(4)係由穿孔(21)裝入該安裝孔(22),而此種安裝方式稱為內塞式,使該固定件(42)被該安裝孔(22)限制其任意方向之自由度,由圖中可見,該安裝孔(22)設有限位部(221)可避免該迴流模組(4)由徑方向(Y)掉出、及環繞該固定件(42)之本體部(421)之壁面(222)而達到限制自由度之效果;而該迴流本體(41)之軸方向(X)的兩端與該安裝孔(22)之壁面(222)係保持一間隙(H),使該迴流本體(41)安裝於該安裝孔(22)後仍能相對該固定件(42)朝軸方向(X)移動。Referring to the fourth figure, the reflow module (4) is inserted into the mounting hole (22) by a through hole (21), and the mounting method is called an inner plug type, so that the fixing member (42) is The mounting hole (22) limits the degree of freedom in any direction. As can be seen from the figure, the mounting hole (22) is provided with a limiting portion (221) to prevent the reflowing module (4) from falling out of the radial direction (Y). And surrounding the wall surface (222) of the body portion (421) of the fixing member (42) to achieve the effect of limiting the degree of freedom; and both ends of the axial direction (X) of the returning body (41) and the mounting hole (22) The wall surface (222) maintains a gap (H) so that the return body (41) can be moved in the axial direction (X) relative to the fixing member (42) after being mounted to the mounting hole (22).
請參閱第五圖及第六圖所示,於裝配該迴流模組(4)時,會如先前技術所述因為加工有些許誤差、或有毛邊之因素造成迴流道(4111)的兩端與滾動槽(211)銜接處有錯位產生(如元件符號G的錯位間距),如第四圖所示,如此即可藉由該迴流本體(41)可相對該固定件(42)位移之功能,來使得該錯位間距(G)消除,而調整時可藉由如第二圖及第三圖所示,利用一調整件(5)(如:一字起子)插設於該滑移部(412)所設之調整槽(4122)後,再施以該調整件(5)力量而使該迴流本體(41)位移;而調整後如第六圖所示,即使該迴流道(4111)與滾動槽(211)能平順銜接,以避免如先前技術之問題產生;而調整後的迴流模組(4)係使用膠黏方式將該固定件(42)與迴流本體(41)相互固定,讓滾珠螺感運行時該固定件(42)與迴流本體(41)不會再產生相對位移。Referring to the fifth and sixth figures, when the reflow module (4) is assembled, the ends of the return channel (4111) may be caused by a slight error or a burr factor as described in the prior art. There is a misalignment at the junction of the rolling groove (211) (such as the misalignment spacing of the component symbol G), as shown in the fourth figure, so that the displacement of the fixing body (42) can be performed by the returning body (41). The offset spacing (G) is eliminated, and the adjusting portion (5) (eg, a word driver) can be inserted into the sliding portion by using an adjusting member (5) as shown in the second and third figures. After the adjustment groove (4122) is set, the force of the adjusting member (5) is applied to displace the return body (41); and after the adjustment, as shown in the sixth figure, even the return path (4111) and the rolling The groove (211) can be smoothly connected to avoid the problem of the prior art; and the adjusted reflow module (4) fixes the fixing member (42) and the return body (41) to each other by adhesive means, and the ball is fixed. screw The fixing member (42) and the return body (41) are no longer in relative displacement during the sense of operation.
再者,請參閱第七圖至第九圖所示,係為本創作第二實施例之圖式,本實施例與第一實施例不同在於:該迴流模組(4)係由螺帽(2)之外部裝入安裝孔(22),該種安裝方式稱為外塞式,而該安裝孔(22)更設有複數螺絲孔(223),該迴流模組(4)之固定件(42)更設有相對該螺絲孔(223)之通孔(4211),於安裝時,先將該固定件(42)與該迴流本體(42)組合後,由螺帽(2)外部將該迴流模組(4)置入該安裝孔(22),使該通孔(4211)及螺絲孔(223)相對設置,再藉由複數螺絲(A)穿設於該通孔(4211)後與該螺絲孔(223)螺合鎖固,以將該固定件(42)定位於該螺帽(2),達成固定該迴流模組之目的,而其餘結構及功效皆與第一實施例相同,在此不再多作贅述。Furthermore, please refer to the seventh to ninth drawings, which is a diagram of the second embodiment of the present invention.
