M382401 五、新型說明： 【新型所屬之技術領域】 [0001] 本創作係有關於一種轉角缸，尤指一種油壓轉角缸的結 構改良。 【先前技術】 [0002] 轉角缸主要使用在空間狹小，且必須旋轉一角度後才能 夠夾持及放鬆工件的工作環境。例如，台灣專利第 M297425號揭示一轉角缸，其主要包括：一外殼、一活塞 心軸、一封蓋、及一導向桿。導向桿上設至少二條導向 曲弧槽，活塞心軸並貫穿設有相對導向曲弧槽之數量的 埋入孔，而各埋入孔係埋設鋼珠，利用二頂迫件分別迫 緊一鋼珠，相對埋入孔之數量的螺孔係分別連通一埋入 孔，並分別由一螺桿鎖於螺孔並迫緊頂迫件。 [0003] 然而，上述的專利案係利用二頂迫件分別推抵鋼珠而迫 抵於導向曲弧槽内，因此，必須設置頂迫件，且頂迫件 的表面必須對應鋼珠而亦形成球凹面；另外，為了確保 頂迫件能夠確實推抵鋼珠，因此必須在活塞心軸上鑽設 穿孔以供頂迫件插入，同時配合垂直抵緊頂迫件以防止 頂迫件移位的螺桿，方能確保頂迫件的正確操作。 [0004] 可想而知，上述轉角缸的結構相當複雜，且所需要的零 件很多，因而提高製造與組裝成本；另一方面，以頂迫 件推抵鋼珠可能會有施力不均勻的情形，導致整個活塞 心軸的移動不滑順；由於導向桿會旋轉一角度，因此對 頂迫件產生一股剪力，因此當鋼珠與頂迫件之間發生移 表單編號A0101 第4頁/共22頁 M382401 位而使導向桿移動與轉動不順時，甚至可能折斷頂迫件 而導致轉角缸卡死。M382401 V. New description: [New technical field] [0001] This creation relates to a corner cylinder, especially a structural improvement of a hydraulic corner cylinder. [Prior Art] [0002] The corner cylinder is mainly used in a working environment where the space is small and must be rotated by an angle to clamp and loosen the workpiece. For example, Taiwan Patent No. M297425 discloses a corner cylinder which mainly comprises: a casing, a piston mandrel, a cover, and a guide rod. At least two guiding curved arc grooves are arranged on the guiding rod, and the piston mandrel is inserted through the embedded holes provided with the number of the opposite guiding curved arc grooves, and the buried holes are embedded with steel balls, and the two pressing members respectively press a steel ball. The screw holes of the number of the buried holes are respectively connected to a buried hole, and are respectively locked by a screw to the screw holes and urge the pressing member. [0003] However, the above patent case uses two pressing members to push against the steel ball and is forced into the curved arc groove. Therefore, the pressing member must be provided, and the surface of the pressing member must correspond to the steel ball and also form a ball. Concave; in addition, in order to ensure that the pressing member can be pushed against the steel ball, it is necessary to drill a hole in the piston mandrel for the insertion of the pressing member, and at the same time, a screw that vertically abuts against the pressing member to prevent the displacement of the pressing member, In order to ensure the correct operation of the top member. [0004] It is conceivable that the structure of the above-mentioned corner cylinder is quite complicated, and many parts are required, thereby increasing manufacturing and assembly costs; on the other hand, pushing the steel ball with the pressing member may have uneven force application. , the movement of the entire piston mandrel is not smooth; because the guide bar will rotate at an angle, a shear force is generated on the top member, so when the steel ball and the top member move, the form number A0101 is made. When the M382401 position on page 22 causes the guide bar to move and rotate incorrectly, it may even break the pressing member and cause the corner cylinder to be stuck.
[0005] 另一方面，鋼珠長期滾動於具圓弧形剖面的曲弧槽及頂 迫件的球凹面内，由於接觸面積大，所以摩擦力大且磨 損較快，摩擦力大會使導向桿移動不順，一旦曲弧槽磨 損過大而與鋼珠之間超過容許的誤差範圍時，鋼珠很容 易脫離曲弧槽，或者頂迫件的球凹面磨損過大而無法確 實掌控鋼珠時，上述任一磨損情況皆使得轉角缸易於故 障。 [0006] 因此，如何解決上述之問題點，即成為本創作人所改良 之目標。 【新型内容】 [0007] 本創作之一目的，在於提供一種轉角缸，其結構簡單， 能夠均勻夾掣滾珠而緊靠於弧形槽道内滾動，且不容易 發生滚珠跑位導致轉角缸故障的問題。[0005] On the other hand, the steel ball is rolled in a curved arc groove with a circular arc profile and a spherical concave surface of the abutting member for a long time. Since the contact area is large, the friction force is large and the wear is fast, and the frictional force causes the guide bar to move. If the arc groove is excessively worn and the tolerance between the steel ball and the steel ball exceeds the allowable error range, the steel ball is easily separated from the curved groove, or the concave surface of the pressing member is excessively worn and the steel ball cannot be controlled. Make the corner cylinder easy to malfunction. [0006] Therefore, how to solve the above problems becomes the goal of improvement by the present creator. [New Content] [0007] One of the aims of the present invention is to provide a corner cylinder which has a simple structure, can uniformly clamp the ball and is pressed against the arcuate channel, and is not prone to ball running and causing the corner cylinder to malfunction. problem.

[0009] In order to achieve the above object, the present invention provides a corner cylinder, comprising: a body having a chamber and a through hole communicating with the chamber; a piston rod movable and rotating relative to the base a portion of the piston rod is received in the chamber, and another portion passes through the through hole from the outside of the housing. The piston rod in the chamber extends with a guiding rod, and the surface of the guiding rod Forming a plurality of arcuate channels; and a cover assembly sealed to the bottom of the chamber, the cover assembly comprising a cover, a plurality of balls, and a ring spring of the form number A0101, page 5 of 22 The cover body is provided with a central hole through which the guide rod is connected, and the teardrops such as X are respectively placed in the arcuate grooves and elastically clamped by the annular magazine. According to another feature of the present invention, the arcuate channel has a V-shaped cross section or a square opening and a combined shape having left and right two guiding slopes. Compared with the prior art, this creation has the following effects: [_Heart ring _ spring lag 0 (10), and with the limitations of the capping assembly, the ball can not slide up and down, but only can actually roll on the arc channel Therefore, there is no problem of arbitrary displacement, so the smooth movement of the piston rod can be read. [0013] According to the above, since the creation does not require the pressing member and the related fastener as in the prior art, the structure can be simplified, the manufacturing and assembly costs can be saved, and the spherical concave surface of the pressing member is not excessively worn and cannot be controlled. The problem of the ball 〇 [0014] In addition, since the arcuate channel of the present invention has a v-shaped cross section, or a square shape and a combined shape having left and right two-lead slopes, instead of the circular arc-shaped concave surface of the prior art, the ball and the ball are The arcuate channels are only linearly contacted, rather than the spherical contact in the prior art, so the friction and wear between the balls and the arcuate channels can be reduced, and the movement of the corner cylinders is smoother and Reduce the number of failures. [Embodiment] [0015] The detailed description and technical contents of the present invention will be described below with reference to the drawings, but the drawings are for illustrative purposes only and are not intended to limit the present invention. Form No. A0101 Page δ / Total 22 pages M382401 [0016] Please refer to the first figure and the second figure, which is a three-dimensional decomposition circle and a three-dimensional combination diagram of the creation. The creation system provides a corner cylinder, and the corner cylinder 1 is mainly A body 10, a piston rod 20, a cover assembly 30, and a pressure plate 40 are included. One end of the piston rod 20 can slide and rotate in the seat body 1b and the other end is connected to the pressure plate 40. By the advancement and retreat and rotation of the piston rod 2, the pressure plate 40 also moves forward and backward and rotates to clamp or loosen a workpiece. (not shown) . Since the shape and structure of the pressure plate are not the features of the present invention and may be conventional, the description of the pressure plate 40 is omitted so as not to be described. Φ [〇〇17] The seat body 10 is the main body of the corner cylinder 1. In the embodiment shown in the first figure, the upper half of the seat body 10 has a rectangular shape and the lower half has a cylindrical shape; the inner body of the seat body 10 is Deng. Having a cavity to 11 and a through hole 12 and 12, the through hole 12 is connected to the chamber 11 and located above the chamber 11; on the four corners of the rectangular upper half of the seat, there is a screw hole 13 for the bolt ( Not shown) the connection, thereby locking the seat 1 〇 in the desired position. An oil inlet hole 14 and an oil outlet hole 15 are defined in a side surface of the upper portion of the base body 10. The oil inlet passage 141 and the oil outlet passage are respectively disposed from the oil inlet hole 4 and the oil outlet port 5 toward the chamber 11. 151, the oil inlet hole 14 and the oil outlet hole 15 are used to control the advancement and retraction of the piston rod 20, which will be described later in detail. [0018] The piston rod 20 has a cylindrical shape, one end of which is connected to the pressure plate 4〇, and the other end is movable and rotatable relative to the base body 10; as shown in the first figure, the piston rod 20 includes: a rod body 21, A piston crown 22 and a guide rod 23. As can be clearly seen from the second figure, except for a part of the rod body 21 which is close to the pressure plate 40, the other rod body 21, the piston pair i22, and the guide rod 23 are barely connected to the through hole 12 of the seat body 1〇. Reciprocating in the chamber n of the housing 1A. Form No. A0101 Page 7 of 22 [0019] M382401 The outer diameter of the rod body 21 is substantially equal to the outer diameter of the through hole 12 of the seat body 1〇, so the rod body 21 The piston crown 22 can be moved and rotated through the through hole 12; the piston crown 22 is disposed on the end of the rod body 21 away from the pressure plate 40, and has an outer diameter substantially equal to the inner diameter of the chamber 11, by a ring disposed around the piston crown 22. The ring 221 can ensure that the oil on the upper and lower sides of the piston crown 22 in the chamber 11 cannot communicate with each other, so that the piston rod 2 can be forwardly retracted or retracted by the oil pressure; the piston crown 22 is away from the rod body 21 A guide rod 23 extends on a surface thereof, the diameter of the guide rod 23 is smaller than that of the rod body 21, and a surface of the guide rod 23 is formed with a plurality of arcuate grooves mi formed at a position close to the piston crown 22 a straight line segment immediately adjacent to the straight line segment and in the vicinity of the guide rod 23 The solitary section shaped as 彳" § 0 degrees, here the so-called 90 degrees means that along the direction of the guide bar 23, the angle covered by the arc segment is 90 degrees; next to the arc The segment is formed with another small straight line segment at the free end of the guide rod 23. Since the curved groove 231 is formed on the surface of the guiding rod 23, the guiding rod 23 can drive the piston crown 22 and the rod body 21 to produce a rotation of 90 degrees; in other words, the entire piston rod 2 can be subjected to the curved channel. The guidance of 231 produces a 9 degree rotation. [0020] The capping assembly 30 is for sealing to the bottom of the seat body 1,, thereby sealing the cavity to 11 so that the oil in the cavity to 11 cannot be leaked; the capping assembly 3 〇 mainly includes a cover body 31. A plurality of balls 32 and a ring spring 33. [0021] As shown in the first figure, the outer shape of the cover body 31 is substantially a first-order cylindrical body, and the upper and lower sides are a set of joint portions 311, a sealing portion 312, and a fixing portion 31 3 . The sleeve portion 311 is located at the uppermost end of the cover body 31 and has the smallest outer diameter. The socket portion 311 is used to sleeve the guide rod 23, and the sleeve portion 311 has a center hole 3111 therein for the guide rod 23 to reciprocate therein. And rotation, wherein the form number A0101, page 8 / total 22 pages M382401, the depth of the core hole 3111 corresponds to the length of the guide rod 23, and thus can extend into the sealing portion 312 and the fixing portion 313; the socket portion 311 and the sealing portion 312 The plurality of ball holes 3112 are provided at the junction, and the number and the (4) system correspond to the number and the aperture of the balls 32, so that the balls 32 can be accommodated in the ball holes 3丨12; the outer diameter of the sealing portion 312 is substantially equal to the chamber The inner diameter of n, and by a ring-shaped ring 3121 disposed around the sealing portion 312, can reliably seal the oil of the chamber to prevent leakage; the outer diameter of the fixing portion 313 is the largest and substantially equal to the seat ίο. The cylindrical outer diameter of the lower half, the inner edge surface of the fixing portion 313 has a plurality of screw holes 3131, and the entire cover can be penetrated through a plurality of screw inspections 5 (the third drawing) through the screw holes 3131. The body 31 is locked to the lower half of the seat body 1〇. [0022] As can be clearly seen from the fourth figure, the roll Zhu 3 2: you are accommodated in the ball hole 3112 of the socket portion 311 and are subjected to the wall of the socket portion 311: 'limited to its movement, and the double bead 3 2 The outer periphery is elastically clamped by the annular spring 3 3 so that it cannot move outward to be separated from the ball hole 3112; in addition, when the guide rod 23 is inserted into the center hole 3111 of the socket portion 311, due to the outer diameter of the guide rod 23 and the socket portion The inner diameter of the 311 is tightly fitted so that the balls 32 can only roll 'in the arcuate channel 231 of the guide bar 23' and cannot escape the arcuate channel 231. [0023] In particular, in the embodiment of the present invention, the cross section of the curved channel 2 31 is not a circular arc-shaped concave surface as in the prior art, but is square as shown in the fourth figure and has The combined shape of the left and right guide bevels is formed by sharply grinding a groove having a square cross section and a width smaller than the outer diameter of the ball 32, and then forming a guide bevel on each of the top sides of the square groove. The two guide bevels abut against the balls 32. Since the present invention abuts the ball 3 2 with the two-lead bevel on the top of the curved channel 2 31 , the arc-inclination channel 2 31 is only in linear contact with the ball 3 2 , and its contact area form number A0101 9 pages/total 22 pages [0024] M382401 is smaller than the spherical contact in the prior art technique, so the friction and wear generated are also small, so that the rolling of the balls 32 on the curved channel 231 can be made more Smooth and extend the life of the curved channel 2 31. In the embodiment of the present invention, the annular magazine 33 is used to evenly apply the force on the ball 32 so as to surround the socket portion 311, thereby avoiding the structural complexity that may occur in the prior art by pushing the ball against the ball. Problems such as large wear and tear. Moreover, in order to enable the ring spring 33 to positively clamp the ball 32, one end of the ring spring 33 is bent and formed with an insertion end 331 (first and fourth figures), and the bottom edge of the socket portion 3π is provided with a socket 3113. By inserting the insertion end 331 of the annular spring 33 into the insertion hole 3113 of the socket portion 311, the annular spring 33 can be securely sleeved around the socket portion 311 without relative sliding in the axial or peripheral direction. ^.

The central screw hole 341 has a central screw hole 341 for screwing the external threads of the socket portion 311 to each other. The guide rod 23 is smoothly passed through; the bottom of the tightening ring 34 is provided with a recess 342 for accommodating the annular spring 33; by means of the vertical wall surface of the recess 342, the annular spring 33 can be prevented from being excessively radially Expanded outside. [0026] Hereinafter, the principle of advancement and retraction of the piston rod 2〇 in the seat body 10 will be described with reference to the fifth and sixth figures. As shown in the fifth figure, when the oil enters the bottom of the chamber 1 from the oil inlet hole 14 of the seat body 1 along the oil inlet 141 (shown by the solid arrow in the fifth figure), the fuel form number A0101 The pressure of 10 pages/total 22 pages [0027] pushes the piston crown 22' upwards and advances the entire piston rod 2: during the advancement of the piston rod 20 upwards 'because the balls 32 are surrounded by the annular spring 33, the socket portion The wall of the ball hole 3111 of the 311 and the orphan channel 231 of the guide bar 23 are limited, so that the ball 32 cannot move up and down, left and right, and can only roll in place, so the ball 32 will roll against the curved channel 231. 'The guide rod 23 is guided by the curved channel 231 and rotated 90 degrees clockwise from the direction of the pressure plate 40 (as indicated by the circular arc arrow above the fifth figure); since the top end of the piston rod 20 is fixed to The platen 40 is such that the platen 40 also rotates 90 degrees clockwise with the piston rod 20. [0028] Conversely, as shown in the sixth figure, when the oil enters the top of the I chamber 11 from the oil outlet hole 15 of the seat body 10 along the oil outlet 151 (shown by the solid arrow of the fifth figure), The pressure of the oil pushes the piston 幡1 gas downward, and the entire piston rod 20 is retracted. During the retraction of the piston rod 20, the ball 32 is closed by the annular spring 33, the ball hole 3111 of the socket portion 311, And the arcuate channel 231 of the guide bar 23 is limited, so that the ball 32 cannot move up and down and left and right, and can only roll in place, so that the ball 32 will roll against the arcuate channel 231, and the guide bar 23 will be curved. The guide of the channel 231 is rotated 90 degrees counterclockwise from the direction of the pressure plate 4 (as indicated by the circular arc arrow in the sixth figure). 'Because the top end of the piston rod 20 is fixed to the pressure plate 40', the pressure plate 40 is caused. Also, the piston rod 2 is rotated 90 degrees counterclockwise. [0029] Although a hydraulic corner cylinder has been utilized as a preferred embodiment of the present invention, the present creation is not limited thereto. The corner cylinder of the present invention can also be applied to a pneumatic angle cylinder; in addition, the isolated channel 231 formed on the guide rod 23 is not limited to 9 degrees, and the rotation of the curved channel 231 can be increased or decreased according to actual needs. Angle range; section of curved channel 231 except for form number A0101 page 11 / total 22 pages M382401 [0033] [0033] [0034] [0036] [0038] [0043] [0043] The form number Α0101 may also be V-shaped in addition to the shape shown by the figure, and also achieves an effect of only making linear contact with the balls 32. In summary, when the "corner cylinder" of Zhiben's creation has industrial applicability, novelty and progressiveness, and the structure of this creation has not been seen in similar products and public use, it fully complies with the requirements of new patent applications and converts patents. The law makes an application. [Simple description of the diagram] The first diagram is an exploded perspective view of the creation. The second picture is a combined perspective view of the creation.
