Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling and fixture for processing end caps. Background Technology
[0002] An end cover is a rear cover installed behind the housing of a motor or other machine. It is commonly known as an "end cover". During the machining of the casting blank of the end cover, the upper and lower end faces of the mounting base on both sides need to be milled with a milling cutter. During the machining process, the end cover needs to remain stable.
[0003] Currently, most end cap processing equipment on the market uses embedded installation to install the end caps before milling the surface. During this process, the end caps are prone to shaking, which leads to lower processing accuracy and is not conducive to the production and processing of end caps. Therefore, this method needs to be improved. Utility Model Content
[0004] This utility model proposes a tooling fixture for end cap processing, which solves the problems mentioned in the above documents.
[0005] The technical solution of this utility model is as follows: A tooling fixture for processing end caps includes a worktable. The top of the worktable has an elongated groove and a sliding groove. A bidirectional threaded rod A is rotatably connected inside the elongated groove. A slide block is slidably connected inside the elongated groove. A clamping seat is fixedly connected to the top of the slide block. A motor is fixedly mounted on the side of the worktable. The output shaft of the motor is fixedly connected to the bidirectional threaded rod A. A processing plate is provided on the top of the worktable. An end cap body is inserted into the front end of the processing plate. An anti-accidental contact clamping mechanism is provided inside the sliding groove. The mechanism includes a bidirectional threaded rod B, a slide rod, and a slider. The bidirectional threaded rod B has an open slot inside, and a compression spring is installed inside the open slot. A retaining groove is formed on the inner wall of the open slot. A handle is fixedly connected to one end of the slide rod, and a round block is fixedly connected to the other end of the slide rod. A groove is formed on the surface of the round block, and a telescopic spring is installed inside the groove. An arc-shaped block is slidably connected inside the groove through the telescopic spring. The slider is slidably connected inside the slide groove. A clamping plate is fixedly connected to the top of the slider, and a bell mechanism is provided on the side of the clamping plate.
[0006] The slide block is threadedly connected to the bidirectional threaded rod A via an internal thread, and the slider is threadedly connected to the bidirectional threaded rod B via an internal thread. When the bidirectional threaded rod A rotates, it will drive the slide block to move along the long groove through the engagement of the threads. When the bidirectional threaded rod B rotates, it will drive the slider to move along the groove through the engagement of the threads.
[0007] The diameter of the circular block is equal to the diameter of the opening slot, and the circular block is located inside the opening slot. The circular block can move or rotate inside the opening slot. When the circular block moves to the right, it will squeeze the compression spring and gradually compress it.
[0008] The end of the arc-shaped block away from the telescopic spring is initially in contact with the inner wall of the opening groove, and the telescopic spring is initially in a compressed state. When the groove and the slot coincide, the telescopic spring will rebound and drive the arc-shaped block into the slot.
[0009] The arc-shaped block is made of stainless steel, and the arc surface of the arc-shaped block faces the direction of the compression spring. The stainless steel arc-shaped block has high strength and is not easily damaged. When the arc surface of the arc-shaped block is squeezed, it will move into the groove.
[0010] The opening size of the slot is equal to the opening size of the groove, and the slots are arranged in a circular array on the inner wall of the opening groove. When the arc-shaped block is inserted into the slot, the rotation of the circular block will drive the bidirectional threaded rod B to rotate through the cooperation between the arc-shaped block and the slot.
[0011] The bell mechanism includes a bell, a bracket, and a rack. The bell is fixedly installed on the side of the clamping plate. The bracket is fixedly connected to the side of the clamping plate. A rotating rod is rotatably connected through the front end of the bracket. An impact block is fixedly connected to the front end of the rotating rod. A gear is fixedly connected to the rear end of the rotating rod. The rack is fixedly connected to the top of the worktable.
[0012] The length of the impact block is greater than the longitudinal distance from the rotating rod to the bottom of the bell. When the rotating rod rotates, it will cause the impact block to repeatedly strike the bell.
[0013] The end of the impact block away from the rotating rod is arc-shaped, and the rotating rod is made of rubber. The rubber impact block is elastic and will not damage the bell.
[0014] The teeth on the gear mesh with the teeth on the rack. When the clamping plate moves, the gear meshes with the rack, causing it to rotate.
[0015] The working principle and beneficial effects of this utility model are as follows:
[0016] 1. In this utility model, by setting an anti-accidental contact clamping mechanism, during the processing of the end cap body, the handle can be pressed and then rotated. At this time, the bidirectional threaded rod B will be rotated through the cooperation of components such as the round block, telescopic spring, arc block, and slot. The rotation of the bidirectional threaded rod B will cause the two sets of clamping plates to clamp the end cap body to prevent shaking. When the handle is released, the compression spring will rebound and drive the round block, slide rod, and handle to move to the left to restore their original position. At this time, rotating the handle again will not drive the bidirectional threaded rod B to rotate, preventing accidental contact that could cause the clamping plates to shift.
[0017] 2. In this utility model, a bell mechanism is provided so that when the bidirectional threaded rod B rotates and drives the two sets of clamping plates to move, the impact block on one set of clamping plates will repeatedly strike the bell through the cooperation of components such as rotating rod, gear, and rack, thereby making the bell ring and reminding the operator to pay attention to the position of their hands to prevent injury to the operator's hands, thus improving safety.

Detailed Implementation
[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1
[0028] like Figures 1-5 As shown, this embodiment proposes a tooling fixture for end cap processing, including a worktable 1. The top of the worktable 1 has an elongated groove 2 and a sliding groove 9. A bidirectional threaded rod A3 is rotatably connected inside the elongated groove 2, and a slide block 4 is slidably connected inside the elongated groove 2. A clamping seat 5 is fixedly connected to the top of the slide block 4. A motor 6 is fixedly mounted on the side of the worktable 1, and the output shaft of the motor 6 is fixedly connected to the bidirectional threaded rod A3. A processing plate 7 is provided on the top of the worktable 1, and an end cap body 8 is inserted into the front end of the processing plate 7. An anti-accidental contact clamping mechanism 10 is provided inside the sliding groove 9. The anti-accidental contact clamping mechanism 10 includes a bidirectional threaded rod B101, a sliding rod 105, and a slider 1011. The bidirectional threaded rod B101 has an elongated groove 2 and a sliding groove 9. The opening 102 has a groove 102, inside which a compression spring 103 is installed. A slot 104 is formed on the inner wall of the opening 102. A handle 106 is fixedly connected to one end of a slide rod 105, and a circular block 107 is fixedly connected to the other end of the slide rod 105. The diameter of the circular block 107 is equal to the diameter of the opening 102, and the circular block 107 is located within the opening 102. The circular block 107 can move or rotate within the opening 102. When the circular block 107 moves to the right, it compresses the compression spring 103, gradually compressing it. A groove 108 is formed on the surface of the circular block 107, inside which a telescopic spring 109 is installed. An arc-shaped block 1010 is slidably connected inside the groove 108 via the telescopic spring 109. Initially, the end of the arc-shaped block 1010 furthest from the telescopic spring 109 is in contact with the inner wall of the opening slot 102, and the telescopic spring 109 is initially compressed. When the groove 108 and the slot 104 overlap, the telescopic spring 109 will rebound, causing the arc-shaped block 1010 to be inserted into the slot 104. The arc-shaped block 1010 is made of stainless steel, and its arc surface faces the compression spring 103. The stainless steel arc-shaped block 1010 has high strength and is not easily damaged. When the arc surface of the arc-shaped block 1010 is compressed, it will move into the groove 108. The opening size of the slot 104 is equal to the opening size of the groove 108, and the slots 104 are arranged in a circular array on the inner wall of the opening slot 102. When the arc-shaped block 1010 is inserted into the slot 104, the rotation of the round block 107 will cause the bidirectional threaded rod B101 to rotate through the cooperation between the arc-shaped block 1010 and the slot 104. The slider 1011 is slidably connected inside the slide groove 9. The slide seat 4 is threadedly connected to the bidirectional threaded rod A3 through the internal thread. The slider 1011 is threadedly connected to the bidirectional threaded rod B101 through the internal thread. When the bidirectional threaded rod A3 rotates, it will cause the slide seat 4 to move along the long groove 2 through the cooperation between the threads. When the bidirectional threaded rod B101 rotates, it will cause the slider 1011 to move along the slide groove 9 through the cooperation between the threads. The top of the slider 1011 is fixedly connected to the clamping plate 1012, and the side of the clamping plate 1012 is provided with a bell mechanism 11.
[0029] In this embodiment, the motor 6 is turned on to drive the bidirectional threaded rod A3 to rotate. The rotation of the bidirectional threaded rod A3 will drive the two sets of clamping seats 5 to clamp the processing plate 7 securely through the engagement of the threads. When the end cap body 8 needs to be processed, the end cap body 8 is inserted into the front end of the processing plate 7. Then, the handle 106 is pressed to drive the slide rod 105 and the round block 107 to move towards the compression spring 103. The compression spring 103 is gradually compressed. When the round block 107 moves and causes the groove 108 to coincide with the slot 104, the telescopic spring 109 rebounds and causes the arc block 1010 to open into the slot 104. At this time, the handle 106 rotates, causing the slide rod 105 and the round block 107 to rotate. When block 107 rotates, the interaction between arc block 1010 and slot 104 drives the bidirectional threaded rod B101 to rotate. The rotation of bidirectional threaded rod B101 drives the two sets of clamping plates 1012 to move and clamp the end cap body 8, preventing shaking during processing and affecting processing accuracy. Then, the handle 106 is released. At this time, the compression spring 103 rebounds and drives the round block 107, slide rod 105, and handle 106 to move back to their original positions. The arc surface of arc block 1010 is squeezed and retracts into groove 108. Groove 108 and slot 104 are repositioned. At this time, rotating handle 106 will not drive the bidirectional threaded rod B101 to rotate, preventing the clamping plate 1012 from shifting due to accidental contact.
[0030] Example 2
[0031] like Figures 1-6 As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. The ringing mechanism 11 includes a ringing bell 111, a bracket 112, and a rack 116. The ringing bell 111 is fixedly installed on the side of the clamping plate 1012. The bracket 112 is fixedly connected to the side of the clamping plate 1012. A rotating rod 113 is rotatably connected through the front end of the bracket 112. An impact block 114 is fixedly connected to the front end of the rotating rod 113. The length of the impact block 114 is greater than the longitudinal distance from the rotating rod 113 to the bottom of the ringing bell 111. When the 3rd rotating rod rotates, it will cause the impact block 114 to repeatedly strike the bell 111. The end of the impact block 114 away from the rotating rod 113 is arc-shaped, and the rotating rod 113 is made of rubber. The rubber impact block 114 is elastic and will not damage the bell 111. The rear end of the rotating rod 113 is fixedly connected to the gear 115, and the rack 116 is fixedly connected to the top of the workbench 1. The teeth on the gear 115 mesh with the teeth on the rack 116. When the clamping plate 1012 moves, the gear 115 meshes with the rack 116, which will cause it to rotate.
[0032] In this embodiment, during the rotation of the bidirectional threaded rod B101, which drives the two sets of clamping plates 1012 to move, the movement of one set of clamping plates 1012 will drive the support 112 and rotating rod 113 on it to move. The movement of the rotating rod 113 will drive the gear 115 to mesh with the rack 116 and thus rotate. The rotation of the gear 115 will drive the rotating rod 113 to rotate. The rotation of the rotating rod 113 will drive the impact block 114 to repeatedly strike the bell 111, thereby making the bell 111 ring and reminding the operator to pay attention to the position of their hands, preventing injury to the operator's hands, and improving safety.
[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
