Description
Technical Field
[0001] This utility model relates to the field of connecting rod copper sleeve processing technology, and in particular to a connecting rod copper sleeve processing clamp. Background Technology
[0002] Copper bushings, also known as copper shaft sleeves, include types such as machine copper rollers and copper bearings. They are suitable for light, large, and heavy machinery and are important components. They are made of electrolytic copper with trace amounts of metal through high-temperature sintering and gas-pressure centrifugal casting. They have high hardness, excellent wear resistance, good sliding self-lubricating properties, and corrosion resistance. They are easy to cut, but require clamping during processing.
[0003] Existing technology, such as the adjustable clamping fixture for machining irregularly shaped copper sleeves disclosed in CN219325156U, includes a mounting groove on a base, a screw connected to one side via a rotating shaft, a knob welded to the end of the screw, and an adjusting block threaded onto the surface. A sliding seat is clamped on the block, with a locking screw inside. A connecting rod is clamped on one side, a spring is attached to the rod, a pressure plate is welded to one end, a limiting plate is welded to the other end, and a handle is mounted on the outside of the plate. There are clamping blocks on both sides of the bottom of the block, and a mating groove is provided inside the groove. This device can effectively clamp copper sleeves of different shapes and sizes, facilitating machining.
[0004] However, this technical solution has the following problems in practical use: One end of the spring contacts one side of the pressure plate, and the other end contacts the inside of one side of the sliding seat. The spring force clamps the copper tube into the sliding seat slot. Releasing the handle allows the pressure plate to contact the surface of the copper tube, ultimately fixing it in place. However, because the spring lacks rigidity and retains its own elasticity, its clamping stability is insufficient. During processing, clamping wobbling can easily occur, affecting processing accuracy and ultimately the final product's finish. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that in the prior art, springs do not have a rigid fixing effect and still have elasticity, resulting in insufficient clamping stability and easy clamping wobbling during processing. Therefore, a connecting rod copper sleeve processing clamp is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A clamping device for machining connecting rod copper sleeves includes a base, a movable seat horizontally slidably disposed on the base, and a circular seat horizontally slidably disposed on the movable seat. A bidirectional lead screw is rotatably connected to the circular seat. A pair of threaded blocks are threadedly connected to the bidirectional lead screw. An L-shaped plate is vertically slidably inserted into the top of the threaded blocks. A clamping plate is fixedly connected to the end of the L-shaped plate. The device also includes: A locking assembly is used to lock the bidirectional lead screw after it has been rotated. The assembly and disassembly components allow workers to quickly assemble and disassemble the L-shaped plate and the clamping plate together.
[0007] Preferably, the locking component includes: Connecting ears, a pair of connecting ears are fixedly connected to the vertical side wall of the U-shaped seat; The worm gear is fixedly sleeved at one end of the bidirectional lead screw that extends to the outside of the spiral seat; The worm is rotatably connected to the opposite sidewalls of the two connecting lugs, and the worm meshes with the worm wheel; A rotating wheel is fixedly sleeved on one end of the worm extending to the opposite sides of the two connecting lugs.
[0008] Preferably, the disassembly / assembly assembly includes: A top groove is formed at the top of the threaded block, and the L-shaped plate and the top groove are vertically slidably inserted into each other; The insert rod is embedded in and horizontally slidably connected to the threaded block, and the insert rod and the L-shaped plate are horizontally slidably inserted into each other; A pull block is fixedly connected to the end of the insertion rod. A spring is sleeved on the insert rod, and both ends of the spring are fixedly connected to the pull block and the threaded block, respectively.
[0009] Preferably, the spiral seat has a sliding opening, and the threaded block and the sliding opening are horizontally slidably connected.
[0010] Preferably, a screw is rotatably connected to the movable seat, a connecting block is threaded onto the screw, and the top of the connecting block is fixedly connected to the U-shaped seat.
[0011] Preferably, the connecting block and the movable seat are horizontally slidably connected.
[0012] Compared with the prior art, the advantages of this utility model are as follows: This invention, through the setting of locking components and bidirectional lead screws, allows the worm to rotate on the connecting lug of the worm gear when the end wheel of the worm is rotated. Because it meshes with the worm wheel of the bidirectional lead screw, it drives the bidirectional lead screw to rotate, driving the threaded block to slide towards each other along the sliding opening. This causes the L-shaped plate and the clamping plate to move closer together and stably clamp the copper sleeve. The self-locking of the worm wheel and worm and the synergistic use of the bidirectional lead screw ensure that the two clamping plates firmly clamp the copper sleeve, preventing the copper sleeve from shaking during processing, thereby ensuring the processing accuracy and the final product quality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figures 1-3 A clamping device for machining copper sleeves with connecting rods includes a base 1, a movable seat 2 horizontally slidably mounted on the base 1, and a rotary seat 3 horizontally slidably mounted on the movable seat 2. A bidirectional lead screw 4 is rotatably connected to the rotary seat 3. The bidirectional lead screw 4, through its own rotation, can simultaneously drive a pair of threaded blocks 5 to move horizontally in opposite directions or away from each other, thereby achieving synchronous adjustment of the distance between the two clamping plates 7 and ensuring the symmetry of clamping. A pair of threaded blocks 5 are threadedly connected to the bidirectional lead screw 4, and the rotary seat 3 provides a stable rotating mounting carrier for the bidirectional lead screw 4. An L-shaped plate 6 is vertically slidably inserted into the top of the threaded block 5, and a clamping plate 7 is fixedly connected to the end of the L-shaped plate 6. The L-shaped plate 6 serves as a connection and force transmission device, transmitting the horizontal movement of the threaded block 5 to the clamping plate 7. At the same time, the L-shaped structure design provides a suitable installation height and position for the clamping plate 7, facilitating better clamping of the workpiece. It also includes; Locking assembly, used to lock the bidirectional lead screw 4 after rotation; The assembly and disassembly components allow workers to quickly assemble and disassemble the L-shaped plate 6 and the clamping plate 7 together.
[0017] Reference Figure 2 The locking assembly includes: a connecting lug 41, a worm gear 42, a worm 43, and a rotating wheel 44.
[0018] A pair of connecting ears 41 are fixedly connected to the vertical side wall of the U-shaped seat 3; a worm gear 42 is fixedly sleeved on one end of the double-acting screw 4 extending to the outside of the U-shaped seat 3; a worm 43 is rotatably connected to the opposite side walls of the two connecting ears 41, and the worm 43 and the worm gear 42 mesh; the worm 43 meshes with the worm gear 42, and drives the worm gear 42 and the double-acting screw 4 to rotate through its own rotation, while utilizing its self-locking characteristic with the worm gear 42 to achieve a locking function, which is simple to operate and reliable in locking. A rotating wheel 44 is fixedly sleeved on one end of the worm 43 extending to the opposite side of the two connecting ears 41. The rotating wheel 44 provides convenient operation for the operator; by rotating the rotating wheel 44, the worm 43 can be easily driven to rotate, facilitating adjustment and locking operations and reducing the difficulty of operation.
[0019] Reference Figures 2-3 The assembly and disassembly components include: top groove 51, insert rod 52, pull block 53, and spring 54.
[0020] A top groove 51 is formed at the top of the threaded block 5, and the L-shaped plate 6 and the top groove 51 are vertically slidably inserted into each other. The top groove 51 provides precise vertical insertion positioning for the L-shaped plate 6, ensuring the accuracy and stability of the connection between the L-shaped plate 6 and the threaded block 5, and also providing a basic structure for the quick assembly and disassembly of the L-shaped plate 6. The insertion rod 52 is embedded in and horizontally slidably connected to the threaded block 5, and the insertion rod 52 and the L-shaped plate 6 are horizontally slidably inserted into each other. The pull block 53 is fixedly connected to the end of the insertion rod 52. The spring 54 is sleeved on the insertion rod 52, and both ends of the spring 54 are fixedly connected to the pull block 53 and the threaded block 5, respectively. The elastic force of the spring 54 can automatically push the insertion rod 52 towards the L-shaped plate 6, ensuring that the insertion rod 52 can be stably inserted into the L-shaped plate 6 when not in operation, ensuring the reliability of the connection. At the same time, only the spring force needs to be overcome during assembly and disassembly, making the operation convenient.
[0021] The sliding opening 8 is provided on the rotary seat 3, and the threaded block 5 and the sliding opening 8 are horizontally slidably connected. The sliding opening 8 and the threaded block 5 are horizontally slidably connected, which guides and limits the movement of the threaded block 5, ensuring that the threaded block 5 can only move smoothly in the horizontal direction under the drive of the bidirectional lead screw 4, avoiding deviation and ensuring the accuracy of clamping.
[0022] A screw 21 is rotatably connected to the movable seat 2, and a connecting block 22 is threadedly connected to the screw 21. The top of the connecting block 22 is fixedly connected to the U-shaped seat 3.
[0023] The connecting block 22 and the movable seat 2 are horizontally slidably connected.
[0024] The functional principle of this utility model can be explained through the following operation methods: Adjust the movable seat 2 on the base 1 so that it slides horizontally to the appropriate processing position; then rotate the screw 21 on the movable seat 2 to drive the threaded connecting block 22 to slide horizontally. Since the connecting block 22 is fixed to the U-shaped seat 3, the lateral position of the U-shaped seat 3 can be adjusted synchronously until the U-shaped seat 3 is in the initial orientation required for processing that matches the width of each copper sleeve. Workpiece clamping operation: Rotate the wheel 44 at the end of the worm 43. The worm 43 rotates on the pair of connecting ears 41 fixed on the vertical side wall of the circular seat 3. Since the worm 43 meshes with the worm wheel 42 fixed at the extension end of the double-acting screw 4, when the worm 43 rotates, it drives the double-acting screw 4 to rotate through the worm wheel 42. The double-acting screw 4 drives a pair of threaded blocks 5 connected by threads to slide horizontally towards each other along the slide 8 of the circular seat 3. An L-shaped plate 6 is vertically inserted into the top groove 51 at the top of the threaded block 5. When the threaded block 5 slides, it drives the L-shaped plate 6 to move synchronously, so that the clamping plate 7 fixed at the end of the L-shaped plate 6 gradually approaches the copper sleeve until the two clamping plates 7 stably clamp the copper sleeve. Disassembly and maintenance procedure: When the clamping plate 7 needs to be replaced or maintained, pull the pull block 53 at the end of the insertion rod 52. The pull block 53 stretches the spring 54 sleeved on the insertion rod 52, so that the insertion rod 52 is removed from the insertion point of the threaded block 5 and the L-shaped plate 6. At this time, the L-shaped plate 6 can be vertically removed from the top groove 51 of the threaded block 5, so that the L-shaped plate 6 and the clamping plate 7 can be disassembled and installed together. After maintenance, the reverse operation can be used to reset and install.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
