Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to an automatic clamping mechanism for accompanying tooling. Background Technology

[0002] Accompanying fixtures are auxiliary devices that move synchronously with workpieces on automated production lines. They integrate positioning, support, and clamping functions, and can move along the conveyor line or equipment station, maintaining the workpiece's stable posture throughout processing, assembly, and inspection, thus adapting to continuous production processes. In automated production lines, workpieces need to continuously move between multiple stations. Manual clamping is inefficient, inaccurate, and prone to safety hazards; therefore, an automatic clamping mechanism for accompanying fixtures is required.

[0003] An automatic clamping mechanism for accompanying tooling automatically completes rapid positioning and reliable clamping of workpieces throughout the entire process of tooling transfer. Through adaptive, linked, or flexible clamping designs in its mechanical structure, it ensures that workpieces remain undisplaced and undamaged during movement, processing, and assembly. Simultaneously, it simplifies manual operation, improves the automation level of the production line, guarantees processing accuracy and production efficiency, and is suitable for batch production scenarios with multiple specifications and workstations. In existing technologies, traditional two-point clamping or non-linkage four-point clamping methods suffer from uneven clamping force and insufficient stability, easily causing workpieces to tilt or deflect during movement or processing. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic clamping mechanism for accompanying tooling, which aims to improve the problems of uneven clamping force and insufficient stability in traditional two-point clamping or non-linkage four-point clamping methods, which can easily cause the workpiece to tilt or deflect during movement or processing.

[0006] The above technical solution involves driving a motor to rotate a shaft, which in turn causes a connecting rod to rotate. This rotation of the connecting rod then moves a support block, which in turn moves the four clamping plates toward the center, achieving a four-point clamping effect. This significantly improves the clamping force on the workpiece and effectively reduces workpiece misalignment during movement.

[0009] Preferably, a locking block is fixedly connected to the outer wall of the sliding column, the outer wall of the locking block is slidably connected to the inner wall of the limiting ring, the outer wall of the limiting ring is provided with a locking groove, and the outer wall of the locking block is slidably connected to the inner wall of the locking groove.

[0012] Preferably, a cylinder is fixedly connected inside the fixing block, a connecting block is fixedly connected to the output end of the cylinder, a toothed column is fixedly connected to the outer wall of the connecting block, a limit strip is slidably connected to the outer wall of the toothed column, and the lower surface of the limit strip is fixedly connected to the inside of the fixing block.

[0013] Preferably, the tooth ends of the toothed column are meshed with gears, a connecting column is fixedly connected inside the gear, the outer wall of the connecting column is rotatably connected to the inside of the fixing block, and the outer wall of the connecting column is fixedly connected to the inside of the fixing plate.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: Refer to Figure 1 and Figure 2 An embodiment of this utility model provides an automatic clamping mechanism for accompanying tooling, including a fixed block 1, a motor 2 fixedly connected inside the fixed block 1, a rotating shaft 3 fixedly provided at the output end of the motor 2, the outer wall of the rotating shaft 3 rotatably connected to the inside of the fixed block 1, a fixed plate 4 fixedly connected to the outer wall of the rotating shaft 3, a connecting rod 5 rotatably connected inside the fixed plate 4, a support block 6 rotatably connected to the outer wall of the connecting rod 5, a placement plate 8 slidably connected to the outer wall of the support block 6, a clamping plate 7 snapped into the inside of the support block 6, a fixed column 11 fixedly connected to the lower surface of the placement plate 8, the lower surface of the fixed column 11 fixedly connected to the upper surface of the fixed block 1, and a sliding component provided on the outer wall of the support block 6; Specifically, the fixing block 1 fixes the motor 2, which drives the rotating shaft 3 to rotate. The rotating shaft 3 fixes the fixing plate 4, which supports the connecting rod 5. One end of the connecting rod 5 rotates inside the fixing plate 4. When the rotating shaft 3 drives the fixing plate 4 to rotate, the fixing plate 4 drives the connecting rod 5 to rotate. The other end of the connecting rod 5 rotates inside the support block 6. When the connecting rod 5 rotates, it drives the support block 6 to move. The support block 6 supports and fixes the clamping plate 7. When the support block 6 moves, it drives the clamping plate 7 to move synchronously. When the clamping plate 7 moves towards the center, it achieves a clamping and fixing effect, thus ensuring the stability of the workpiece. The design of four clamping plates 7 can better fix the workpiece and avoid deviation. The fixing block 1 fixes the fixing column 11, which fixes the placement plate 8. The outer wall of the clamping plate 7 is provided with a silicone pad to avoid hard contact with the workpiece and reduce damage to the workpiece. The placement plate 8 is used to place the workpiece. The fixing block 1 can be fixed to the production line with bolts.

[0020] Reference Figure 2 The sliding component includes a slider 9, the outer wall of which is fixedly connected to the outer wall of the support block 6, the outer wall of which is slidably connected to the inner wall of the shelf 8, and a limiting groove 10 is formed inside the shelf 8. The outer wall of the slider 9 is slidably connected to the inner wall of the limiting groove 10. Specifically, the support block 6 has a fixing effect on the slider 9, and the limiting groove 10 opened inside the shelf 8 has a supporting and limiting offset effect on the slider 9, so that the slider 9 can only move back and forth in a straight line inside the limiting groove 10. By sliding the slider 9 inside the limiting groove 10, the support block 6 can move in a straight line.

[0021] Reference Figure 1 and Figure 3 A limiting ring 12 is fixedly connected to the outer wall of the support block 6, and a sliding column 13 is slidably connected inside the limiting ring 12; a locking block 14 is fixedly connected to the outer wall of the sliding column 13, and the outer wall of the locking block 14 is slidably connected to the inner wall of the limiting ring 12. A locking groove 15 is opened on the outer wall of the limiting ring 12, and the outer wall of the locking block 14 is slidably connected to the inner wall of the locking groove 15. Specifically, the support block 6 has a fixing effect on the limiting ring 12, and the limiting ring 12 has a supporting and limiting offset effect on the sliding column 13, so that the sliding column 13 can move back and forth linearly inside the limiting ring 12. The sliding column 13 has a fixing effect on the locking block 14, and the locking block 14 slides on the inner wall of the slot 15. The slot 15 is designed in an L shape. After pushing the locking block 14 to move the sliding column 13, by rotating the locking block 14, the locking block 14 can be locked on the inner wall of the short side of the slot 15, thereby achieving the limiting effect on the locking block 14.

[0022] Reference Figure 3The outer wall of the locking block 14 is rotatably connected to a sliding post 16, the outer wall of the sliding post 16 is slidably connected to the inside of the support block 6, the outer wall of the sliding post 16 is fixedly connected to a limiting post 18, the outer wall of the limiting post 18 is slidably connected to the inside of the support block 6, and the outer wall of the limiting post 18 is locked into the inside of the clamping plate 7; a spring 17 is sleeved on the outer wall of the sliding post 16, one end of the spring 17 is fixedly connected to the inside of the support block 6, and the other end of the spring 17 is fixedly connected to the outer wall of the limiting post 18; Specifically, the locking block 14 supports the sliding column 16, and the support block 6 supports and limits the sliding column 16, allowing the sliding column 16 to move linearly only inside the support block 6. When the sliding column 13 moves, the sliding column 16 moves synchronously inside the support block 6. The movement of the sliding column 16 will drive the limiting column 18 to move synchronously. When the limiting column 18 moves, the spring 17 will be stretched, and the outer wall of the limiting column 18 will be locked inside the clamping plate 7, limiting and shifting the clamping plate 7, thus fixing the clamping plate 7 inside the support block 6, thereby achieving the function of starting installation and disassembly. After the spring 17 is stretched, it will generate a contraction force. The elastic force of the spring 17 will generate a squeezing force on the locking block 14. Since the locking block 14 is locked inside the groove 15, the locking block 14 will be more stably locked inside the groove 15, ensuring the stability of the sliding column 16 and the sliding column 13.

[0023] Example 2: Refer to Figure 4 and Figure 5 A cylinder 19 is fixedly connected inside the fixed block 1. A connecting block 20 is fixedly connected to the output end of the cylinder 19. A toothed column 21 is fixedly connected to the outer wall of the connecting block 20. A limit strip 24 is slidably connected to the outer wall of the toothed column 21. The lower surface of the limit strip 24 is fixedly connected to the inside of the fixed block 1. A gear 22 is meshed with the tooth end of the toothed column 21. A connecting column 23 is fixedly connected inside the gear 22. The outer wall of the connecting column 23 is rotatably connected to the inside of the fixed block 1. The outer wall of the connecting column 23 is fixedly connected to the inside of the fixed plate 4. Specifically, in this embodiment, the fixing block 1 has a fixing effect on the cylinder 19. Driving the cylinder 19 will cause the connecting block 20 to drive the gear column 21 to move. The bottom of the gear column 21 is provided with a protrusion. The protrusion slides on the inner wall of the limiting strip 24. The limiting strip 24 has a supporting and limiting offset function for the gear column 21, so that the gear column 21 can only move linearly back and forth. The gear column 21 and the gear 22 are meshed. When the gear column 21 moves, it will drive the gear 22 to rotate. The gear 22 has a fixing effect on the connecting column 23. The fixing block 1 has a supporting effect on the connecting column 23. The rotation of the gear 22 will cause the connecting column 23 to rotate, thereby causing the fixing plate 4 to rotate, thereby achieving the effect of clamping the clamping plate 7 in the center.

[0024] Working principle: When needed, the drive motor 2 drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the fixed plate 4 to rotate. The rotation of the fixed plate 4 drives the connecting rod 5 to rotate inward. Then, the connecting rod 5 drives the support block 6 to move the slider 9 within the inner wall of the limiting groove 10. The movement of the support block 6 drives the clamping plate 7 to move synchronously, thus achieving four-point clamping and greatly improving the clamping effect. Similarly, the drive cylinder 19 drives the connecting block 20 to move the toothed column 21. The movement of the toothed column 21 drives the gear 22 to rotate through meshing. The rotation of the gear 22 causes the connecting column 23 to drive the limiting strip 24 to rotate, which in turn drives the fixed plate 4 to rotate, so that the clamping plate 7 can achieve the clamping effect. By pushing the locking block 14, the sliding column 13 moves, which in turn causes the sliding column 16 to move inside the support block 6. The movement of the sliding column 16 then causes the limiting column 18 to move. After the limiting column 18 moves, its outer wall locks into the clamping plate 7, thus limiting and fixing the clamping plate 7. Simultaneously, the movement of the limiting column 18 stretches the spring 17, and the rebound force generated by the spring 17 pushes the locking block 14 outward. By rotating the locking block 14, it locks into the inner wall of the slot 15. The rebound force of the spring 17 will cause the locking block 14 to be stably locked in the inner wall of the slot 15, thereby ensuring the stability of the sliding column 16 and making the limiting column 18 stably locked in the inside of the clamping plate 7. This device can not only mechanically link and force the four clamping plates 7 to move synchronously towards the center, but also achieve uniform distribution of clamping force and self-centering effect, greatly improving the clamping force on the workpiece, thereby effectively suppressing the workpiece's deviation and vibration. At the same time, it can also quickly replace the worn clamping plates 7, shorten maintenance time, and greatly improve work efficiency.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
