Description

Technical Field

[0001] This utility model specifically relates to a jig for processing auto parts, belonging to the field of parts jig technology. Background Technology

[0002] When assembling or repairing auto parts, it is often necessary to use fixtures to limit their spatial displacement, so that the parts are in a stable position and to prevent them from shaking during subsequent assembly and repair operations.

[0003] A search revealed that CN222450010U discloses a processing fixture for auto parts. The first and second clamping plates of this utility model can clamp and fix plates and pipes. The positions of the first and second clamping plates can be adjusted by the adjustment component, making them easy to replace. When clamping and fixing different parts, there is no need to change the fixture, making it convenient to use.

[0004] However, this solution has limitations when clamping three-dimensional automotive parts (such as engine blocks and transmission housings). It can only clamp and fix the bottom of the parts, and lacks a corresponding clamping structure for the upper part. This makes the parts unstable during maintenance or assembly, and they are prone to shaking, which affects subsequent operations.

[0005] To address the above problems, this application proposes a jig for processing auto parts. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a processing fixture for automotive parts. By designing bottom and upper clamping components, the lower end of a three-dimensional automotive part is placed on a fixed platform, and the lower clamping plates move towards each other to fix the bottom. The threaded screw adjusts the height of the upper clamping plate to match the upper part, and the rotating plate adjusts its clamping position. The upper part of the part is clamped by the upper clamping plate, thereby forming multi-directional limiting through the coordinated clamping of the bottom and upper four sides, which greatly improves stability, avoids shaking during subsequent operations, and solves the problems mentioned in the background technology.

[0007] A jig for machining auto parts, comprising:

[0008] The bottom clamping assembly includes a cylindrical fixed platform, two sets of fixed plates are installed on the top of the fixed platform, and a set of lower clamping plates is provided on the side of the two sets of fixed plates that are close to each other. A rocker screw is threaded to the center of the fixed plate.

[0009] The upper clamping assembly includes uprights on both sides above the fixed platform. A threaded screw is installed inside the upright, and an inner slider is threadedly connected to the threaded screw. A sliding frame is slidably connected to the outside of the upright. A set of hollow rods is installed on both sides of the sliding frame. A push frame is slidably connected inside the hollow rod. An upper clamping plate is connected to the front end of the push frame, and a crank screw is threadedly connected to the middle of its rear. A rotating plate is rotatably provided on the outside of the fixed platform. An external gear ring is fixedly installed in the middle of the lower surface of the rotating plate, and a gear is meshed with one side of the external gear ring.

[0010] The internal support assembly includes an upper support plate installed below the upper clamping plate and a lower support plate installed above the lower clamping plate, wherein a support plate is installed on one side of the lower support plate.

[0011] In a preferred embodiment, a set of guide rods are slidably connected to both sides of the fixed plate, the front end of the guide rods is fixedly connected to the lower clamping plate, and the front end of the crank screw is rotatably connected to the lower clamping plate.

[0012] In a preferred embodiment, a set of sliding grooves are respectively opened on opposite sides of the two sets of uprights. The threaded screw is rotatably installed in the sliding groove, and the inner slider is slidably connected to the sliding groove. One end of the inner slider is fixedly connected to the sliding frame. A height adjustment motor is installed at the top of the upright, and the output shaft of the height adjustment motor is connected to the threaded screw.

[0013] In a preferred embodiment, one front end of the crank screw is rotatably connected to the sliding frame, a clearance rod is installed at the lower end of the upright, the lower end of the clearance rod is fixedly connected to the rotating plate, the clearance rod is a bent structure, and the two sets of clearance rods are installed in a mirror image.

[0014] In a preferred embodiment, the external gear ring is disposed on the outside of the fixed platform, a drive motor is disposed below the gear, the output shaft of the drive motor is fixedly connected to the gear, and its housing is fixedly connected to the fixed platform through a connecting plate.

[0015] In a preferred embodiment, a support base is connected below the fixed platform, and a controller is installed on one side of the support base. The controller is electrically connected to the drive motor and the height adjustment motor, and the rotating plate is rotatably connected to the upper end of the support base.

[0016] In a preferred embodiment, a set of limiting rings is provided on the upper and lower surfaces of the middle position of the rotating plate. The limiting rings are fixedly connected to the fixed platform. Multiple sets of balls are circumferentially and evenly installed on the opposite side of the two sets of limiting rings. One end of each ball is in contact with the upper and lower surfaces of the rotating plate.

[0017] In a preferred embodiment, the side of the lower support plate near the fixed plate and the side of the upper support plate near the upright are both arc-shaped surfaces, and the arc-shaped surfaces are provided with a rubber anti-slip coating. Rubber anti-slip pads are installed on the opposite sides of the two sets of upper clamping plates and the opposite sides of the two sets of lower clamping plates, respectively.

[0018] Beneficial effects:

[0019] 1. By designing bottom and top clamping components, the lower end of a three-dimensional automotive part (such as a cylinder block or housing) is placed on a fixed platform. The two sets of lower clamping plates can move towards each other to achieve bottom clamping and fixation. At the same time, the threaded screw can drive the inner slider to raise and lower to adjust the height of the sliding frame, so that the upper clamping plate is adapted to the upper clamping position of the part. With the rotation of the rotating plate, the clamping position of the two sets of upper clamping plates is adjusted. The upper clamping plate clamps the upper part of the part, and then the bottom and top four sides work together to form multi-directional limit on the part, which greatly improves the clamping stability and ensures that the part is not easy to shake during subsequent operations.

[0020] 2. By designing a lower support plate, an upper support plate, and a support plate, the positioning requirements of hollow cylindrical parts (such as brake drums and spare tire covers) can be met. The upper and lower sides of the parts can be fitted onto the outer sides of the upper and lower support plates, respectively, and the bottom of the parts can be supported by the support plate. The arc-shaped surfaces of the upper and lower support plates can fit against the inner wall of the parts. The internal support and fixation of the cylindrical parts can be achieved by the pull-back movement of the upper and lower clamping plates. This facilitates maintenance or assembly operations on the surface of the parts and reduces obstruction, ensuring surface exposure. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, a jig for processing auto parts includes:

[0029] The bottom clamping assembly includes a cylindrical fixed platform 1, with two sets of fixed plates 15 installed on the top of the fixed platform 1. A set of lower clamping plates 18 is provided on the side of the two sets of fixed plates 15 that are close to each other. A crank screw 16 is threadedly connected to the center of the fixed plate 15.

[0030] The upper clamping assembly includes uprights 5 on both sides above the fixed platform 1. A threaded screw 21 is installed inside the uprights 5. An inner slider 27 is threadedly connected to the threaded screw 21. A sliding frame 8 is slidably connected to the outside of the uprights 5. A set of hollow rods 9 are installed on both sides of the sliding frame 8. A push frame 10 is slidably connected inside the hollow rods 9. An upper clamping plate 13 is connected to the front end of the push frame 10. A crank screw 11 is threadedly connected to the middle of the rear of the push frame 10. A rotating plate 2 is rotatably provided on the outside of the fixed platform 1. An external gear ring 26 is fixedly installed in the middle of the lower surface of the rotating plate 2. A gear 22 is meshed with one side of the external gear ring 26.

[0031] The internal support assembly includes an upper support plate 14 installed below the upper clamping plate 13 and a lower support plate 19 installed above the lower clamping plate 18, with a support plate 20 installed on one side of the lower support plate 19.

[0032] Please see Figures 1-2 As shown, a set of guide rods 17 are slidably connected to both sides of the fixed plate 15. The front end of the guide rod 17 is fixedly connected to the lower clamping plate 18, and the front end of the crank screw 16 is rotatably connected to the lower clamping plate 18. The guide rods 17 provide guidance for the movement of the lower clamping plate 18, ensuring that the lower clamping plate 18 moves linearly under the drive of the crank screw 16.

[0033] Please see Figures 1-3 As shown, each of the two sets of uprights 5 has a set of sliding grooves 7 on opposite sides. The threaded screw 21 is rotatably installed in the sliding groove 7, and the inner slider 27 is slidably connected to the sliding groove 7. One end of the inner slider 27 is fixedly connected to the sliding frame 8. A height adjustment motor 12 is installed at the top of the upright 5. The output shaft of the height adjustment motor 12 is connected to the threaded screw 21. The sliding groove 7 serves to install and guide the threaded screw 21 and the inner slider 27. The height adjustment motor 12 drives the threaded screw 21 to rotate, and through the inner slider 27, drives the sliding frame 8 to rise and fall along the upright 5, thereby adjusting the height of the upper clamping plate 13 to adapt to the clamping position of the upper part of the three-dimensional auto parts of different heights.

[0034] Please see Figures 1-2 As shown, the front end of the crank screw 11 is rotatably connected to the sliding frame 8, and the lower end of the upright 5 is equipped with a relief rod 6. The lower end of the relief rod 6 is fixedly connected to the rotating plate 2. The relief rod 6 has a bent structure, and the two sets of relief rods 6 are installed in a mirror image. The bent relief rod 6 can make way for the bottom clamping component during the rotation of the rotating plate 2 to avoid mutual interference.

[0035] Please see Figure 4 As shown, the external gear ring 26 is located on the outside of the fixed platform 1, and the drive motor 23 is located below the gear 22. The output shaft of the drive motor 23 is fixedly connected to the gear 22, and its housing is fixedly connected to the fixed platform 1 through the connecting plate. The drive motor 23 drives the gear 22 to rotate, and the gear 22 meshes with the external gear ring 26, thereby driving the rotating plate 2 to rotate and realize the adjustment of the clamping position of the upper clamping plate 13.

[0036] Please see Figures 1-2 As shown, a support base 3 is connected below the fixed platform 1, and a controller 4 is installed on one side of the support base 3. The controller 4 is electrically connected to the drive motor 23 and the height adjustment motor 12. The rotating plate 2 is rotatably connected to the upper end of the support base 3.

[0037] Please see Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, a set of limiting rings 24 are respectively provided on the upper and lower surfaces of the middle position of the rotating plate 2. The limiting rings 24 are fixedly connected to the fixed platform 1. Multiple sets of balls 25 are evenly installed on the opposite side of the two sets of limiting rings 24 in a circumferential direction. One end of the balls 25 contacts the upper and lower surfaces of the rotating plate 2. The limiting rings 24 can restrict the position of the rotating plate 2 and prevent it from sliding up and down. The balls 25 convert the sliding friction between the rotating plate 2 and the limiting rings 24 into rolling friction, reducing the resistance when the rotating plate 2 rotates and making the rotation smoother.

[0038] Please see Figures 1-2As shown, the side of the lower support plate 19 near the fixed plate 15 and the side of the upper support plate 14 near the upright 5 are both arc-shaped surfaces. These arc-shaped surfaces are coated with a rubber anti-slip coating. Rubber anti-slip pads are installed on the opposite sides of the two sets of upper clamping plates 13 and the opposite sides of the two sets of lower clamping plates 18. The position of the support plate 20 is higher than the upper surface of the fixed plate 15. The arc-shaped surfaces and rubber anti-slip coatings of the lower support plate 19 and the upper support plate 14 can fit tightly against the inner wall of the hollow cylindrical parts, increasing friction and achieving reliable internal support. The rubber anti-slip pads of the upper clamping plates 13 and the lower clamping plates 18 can increase the clamping friction and prevent the parts from sliding.

[0039] In practical use, the working principle of this utility model is as follows:

[0040] In use, the lower end of the three-dimensional component is placed on the fixed platform 1. The two sets of crank screws 16 are rotated to drive the two sets of lower clamping plates 18 to move towards each other along the path of the guide rod 17 through threaded transmission, thereby clamping and fixing the bottom of the component. At the same time, the height adjustment motor 12 is started by the controller 4, which drives the threaded screw 21 to rotate, thereby driving the inner slider 27 to rise and fall along the slide groove 7, thereby adjusting the height of the sliding frame 8 so that the upper clamping plate 13 is adapted to the upper clamping position of the component. Then, the drive motor 23 is started by the controller 4 to drive the gear 22 to mesh with the outer gear ring 26, thereby rotating the rotating plate 2 to adjust the clamping position of the upper clamping plate 13. Then, by rotating the crank screw 11, the push frame 10 is driven to move along the path defined by the hollow rod 9 through threaded transmission, so that the two sets of upper clamping plates 13 move towards each other to clamp the upper part of the component. Finally, the four sides of the bottom and top are coordinated to form a multi-directional limiting fixation for the three-dimensional component.

[0041] For hollow cylindrical parts, the upper and lower sides can be respectively fitted onto the outer sides of the upper support plate 14 (the position of the upper support plate 14 can be adjusted in conjunction with the above) and the lower support plate 19. The bottom of the part is supported by the support plate 20. The arc surfaces of the upper support plate 14 and the lower support plate 19 are in contact with the inner wall of the part. The internal support and fixation of the cylindrical part is achieved by the pull-back movement of the upper clamping plate 13 and the lower clamping plate 18 (by rotating the rocker screw 11 and the rocker screw 2 16 in the opposite direction, the upper clamping plate 13 and the lower clamping plate 18 are driven to move towards the sliding frame 8 and the fixed plate 15 respectively through the thread transmission). This meets the clamping and positioning requirements of different types of auto parts.
