Description

Technical Field

[0001] This utility model relates to the field of bushing processing technology, specifically a bushing batch processing fixture. Background Technology

[0002] A bushing is a component used on the outside of mechanical parts to achieve functions such as sealing and wear protection. It refers to a ring that acts as a gasket. When processing bushings, it is necessary to use a fixture to clamp and position them.

[0003] A search revealed a Chinese patent with publication number CN217890753U that discloses a fixture for mass-producing bushings. The key technical point of this fixture is that it solves the problem that bushings are easily deformed by downward pressure during the pressing process of a circular pressure plate, which affects the processing quality of the bushings and easily leads to defective products.

[0004] However, in the above-mentioned solution, it was found that when clamping the bushing, the clamping plate is connected to the bidirectional threaded rod, and the two sides are limited by the fixed frame, which makes it impossible to replace the clamping plate and the slot, resulting in the inability to clamp bushings of different sizes and low applicability. In order to solve the problem of the inability to replace the clamping plate in the prior art, which leads to the inability to clamp bushings of different sizes and low applicability, this application sets up components such as pins and springs. The springs enable the pins to connect and disconnect with the sliding block, so as to achieve the effect of replacing the clamping parts. This facilitates the replacement of the appropriate clamping parts according to the bushings of different sizes, thereby improving the applicability of the device. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The aforementioned background technology addresses the shortcomings and defects of existing technologies, such as the inability to replace the clamping plate, which prevents the clamping of bushings of different sizes and results in low applicability.

[0006] This utility model discloses a bushing batch processing fixture, comprising two mounting blocks, two connecting plates, and a base. Each mounting block has a sliding groove on its adjacent side, and a sliding block is slidably connected to the inner wall of each sliding groove. Each sliding block has a mounting plate fixedly connected to its adjacent side, and each mounting plate has clamping members arranged at equal intervals fixedly connected to its adjacent side. Each connecting plate has two pins fixedly connected to its inner wall, and the outer surface of each pin is slidably connected to the inner wall of the corresponding mounting block and sliding block. Each connecting plate has springs arranged at equal intervals fixedly connected to its adjacent side, and the other end of each spring is fixedly connected to the opposite side of the corresponding mounting block.

[0007] Furthermore, each of the mounting blocks has two limiting blocks fixedly connected to its opposite side, and each limiting block has a limiting groove inside, with the inner wall of each limiting groove slidingly connected to the outer surface of the corresponding pin.

[0008] Furthermore, the upper surface of the base is fixedly connected with equidistant positioning pins, and the bottom surface of the base is fixedly connected with a mounting bracket.

[0009] Furthermore, a motor is fixedly connected to the bottom surface of the mounting bracket, a pulley is fixedly connected to the output shaft of the motor, and a transmission belt is connected to the outer surface of the pulley.

[0010] Furthermore, a second pulley is connected to the inner wall of the transmission belt, and a bidirectional threaded rod is fixedly connected to the back of the second pulley.

[0011] Furthermore, the bottom surface of the base has two connecting grooves, and the inner wall of each connecting groove is slidably connected to a connecting block. The inner wall of each connecting block is threadedly connected to the outer surface of the bidirectional threaded rod.

[0012] Furthermore, the upper surface of the base is provided with equidistant connecting grooves II, and each connecting groove II has a connecting block II slidably connected to its inner wall. The upper surfaces of each connecting block I and connecting block II are fixedly connected to the bottom surface of the corresponding mounting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a sliding block, mounting plate, connecting plate, pin, and spring, allows for the stretching of multiple springs when different sizes of bushings need to be processed. This stretches the connecting plate and moves the corresponding pin, releasing the limiting position of the sliding block through the pin. The sliding block can then be pulled out from the sliding groove, allowing the mounting plate and the surface-mounted clamping parts to be removed. A new mounting plate and clamping parts can then be replaced. This device enables the quick replacement of clamping parts according to the size of the bushing, facilitating the clamping of bushings of different sizes.

[0015] 2. This utility model includes components such as pulley one, transmission belt, pulley two, double-threaded rod, connecting block one, and connecting block two. The motor drives pulley one to rotate, and pulley one, transmission belt, and pulley two cause the double-threaded rod to rotate. The connection between the double-threaded rod and the two connecting blocks one allows the two connecting blocks one to drive the two mounting blocks to move relative to each other, thereby causing the clamping components to move relative to each other and clamping the bushing. When the mounting blocks move, the connecting blocks two, which are fixed to the bottom surface of the mounting blocks, limit the movement of the mounting blocks and ensure the stability of the mounting blocks during movement.

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model discloses a bushing batch processing fixture, which includes two mounting blocks 1, two connecting plates 6, and a base 11. Each mounting block 1 has a sliding groove 2 on its adjacent side. The sliding groove 2 is positioned on the adjacent side of the corresponding mounting block 1. A sliding block 3 is slidably connected to the inner wall of each sliding groove 2. The sliding block 3 is placed inside the corresponding sliding groove 2 and is set to slide. The contour of the sliding groove 2 can achieve the limiting effect of the sliding block 3.

[0024] like Figure 3As shown, each sliding block 3 has a mounting plate 4 fixedly connected to its adjacent side. The mounting plate 4 is installed on the adjacent side of the corresponding sliding block 3 to achieve the positioning and installation effect of the mounting plate 4. The mounting plate 4 can be moved by moving the sliding block 3. Each mounting plate 4 has a clamping member 5 fixedly connected to its adjacent side at equal distances. The clamping member 5 is installed on the surface of the mounting plate 4. The bushing can be clamped by the relative movement of the two clamping members 5.

[0025] In a preferred embodiment, two pins 7 are fixedly connected to the inner wall of each connecting plate 6. The pins 7 are installed on the inner wall of the corresponding connecting plate 6 and are set as fixed connections. The relative movement of the pins 7 can be achieved by moving the connecting plate 6. The outer surface of each pin 7 is slidably connected to the inner wall of the corresponding mounting block 1 and sliding block 3. The pins 7 are connected to the corresponding mounting block 1 and sliding block 3 and are set as sliding connections. When the pins 7 are connected to the sliding block 3, the sliding block 3 can be limited and locked.

[0026] In this embodiment, each connecting plate 6 has a spring 8 arranged at equal intervals fixedly connected to the side of each connecting plate 6 that is close to each other. The other end of each spring 8 is fixedly connected to the side of the corresponding mounting block 1 that is far from each other. Connecting the other end of the spring 8 to the mounting block 1 achieves the positioning and installation effect of the spring 8. The connecting plate 6 can be tightened by the spring 8, so that the pin 7 and the sliding block 3 will not be separated. The pin 7 can only be moved by the operator.

[0027] Looking back Figure 3 Each mounting block 1 has two limiting blocks 9 fixedly connected to its opposite side. The limiting blocks 9 are installed on the opposite side of the mounting block 1 to achieve the positioning and installation effect of the limiting blocks 9. Each limiting block 9 has a limiting groove 10 inside. The inner wall of each limiting groove 10 is slidably connected to the outer surface of the corresponding pin 7. The limiting groove 10 is opened inside the corresponding limiting block 9 to achieve the positioning of the limiting groove 10. The limiting groove 10 is connected to the corresponding pin 7. The pin 7 is limited by the contour of the limiting groove 10.

[0028] In a preferred embodiment, a positioning pin 12 arranged at equal intervals is fixedly connected to the upper surface of the base 11. The positioning pin 12 is installed on the upper surface of the base 11 to facilitate the initial positioning of the bushing clamp. A mounting bracket 13 is fixedly connected to the bottom surface of the base 11. The mounting bracket 13 is set on the bottom surface of the base 11 to realize the installation of the mounting bracket 13.

[0029] In this embodiment, a motor 14 is fixedly connected to the bottom surface of the mounting bracket 13. The mounting bracket 13 supports the motor 14 and ensures that the motor 14 can operate stably. A pulley 15 is fixedly connected to the output shaft of the motor 14. The pulley 15 is mounted on the output shaft of the motor 14 and fixedly connected to it. The rotation of the pulley 15 can be achieved by the motor 14. A transmission belt 16 is connected to the outer surface of the pulley 15. The transmission belt 16 is connected to the pulley 15 to form a transmission connection.

[0030] Combination Figure 2 and Figure 4 The inner wall of the transmission belt 16 is connected to a pulley 17. The pulley 17 is installed on the other side of the transmission belt 16 and connected to it. Transmission is easily achieved through the pulley 15, the transmission belt 16 and the pulley 17. A bidirectional threaded rod 18 is fixedly connected to the back of the pulley 17. The bidirectional threaded rod 18 is installed on the inner wall of the pulley 17 and is set as a fixed connection. The rotation of the pulley 17 realizes the rotation of the bidirectional threaded rod 18. The bidirectional threaded rod 18 is rotatably connected to the base 11 to limit the movement of the bidirectional threaded rod 18.

[0031] In a preferred embodiment, two connecting grooves 19 are formed on the bottom surface of the base 11. The connecting grooves 19 are formed on the bottom surface of the base 11 and penetrate through the base 11 to achieve positioning of the connecting grooves 19. A connecting block 20 is slidably connected to the inner wall of each connecting groove 19. The inner wall of each connecting block 20 is threadedly connected to the outer surface of the bidirectional threaded rod 18. The connecting block 20 is installed inside the corresponding connecting groove 19 and is set as a sliding connection to limit the position of the connecting block 20. The bidirectional threaded rod 18 is connected to the connecting block 20 and is set as a threaded connection. When the bidirectional threaded rod 18 rotates, the two connecting blocks 20 can move relative to each other.

[0032] In this embodiment, the upper surface of the base 11 is provided with equidistantly arranged connecting grooves 21. The connecting grooves 21 are positioned on the upper surface of the base 11. Each connecting groove 21 has a connecting block 22 slidably connected to its inner wall. The connecting block 22 is installed inside the corresponding connecting groove 21 and is set as a sliding connection. The contour of the connecting groove 21 can limit the position of the connecting block 22. The upper surface of each connecting block 1 20 and connecting block 22 is fixedly connected to the bottom surface of the corresponding mounting block 1. The connecting block 1 20 and connecting block 22 are connected to the corresponding mounting block 1, thereby limiting the position of the mounting block 1.

[0033] The implementation principle is as follows: The bushing is placed at the position of the corresponding positioning pin 12. The motor 14 drives the pulley 15 to rotate. The pulley 15, the transmission belt 16 and the pulley 17 cause the bidirectional threaded rod 18 to rotate. The bidirectional threaded rod 18 is connected to the two connecting blocks 20, so that the two connecting blocks 20 can drive the two mounting blocks 1 to move relative to each other, thereby causing the clamping parts 5 to move relative to each other and clamp the bushing. When it is necessary to process bushings of different sizes, the connecting plate 6 is pulled to stretch the multiple springs 8 and drive the corresponding pins 7 to move. At this time, the pins 7 release the limit on the sliding block 3, so that the sliding block 3 can be pulled out from the inside of the sliding groove 2, the mounting plate 4 can be taken out, and the clamping parts 5 installed on the surface of the mounting plate 4 can be taken out. Then, a new mounting plate 4 and clamping parts 5 can be replaced, which is convenient for clamping bushings of different sizes.

[0034] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
