Description

Technical Field

[0001] This utility model relates to the field of automotive bumper processing technology, specifically to a painting fixture for automotive bumpers. Background Technology

[0002] A painting fixture for car bumpers is an auxiliary device specifically designed for car bumper painting lines. Its main function is to fix and support the bumper during the painting process, ensuring the uniformity of the coating and the quality of the paint finish. Painting fixtures are typically made of corrosion-resistant materials and are designed as clamps or brackets that match the shape of the bumper. They can automatically or manually load the bumper onto the painting line and maintain its stability throughout the painting process, preventing painting defects caused by shaking or deformation. Using painting fixtures can improve production efficiency, guarantee paint quality, and reduce labor intensity.

[0003] Currently, painting fixtures have positioning and support structures to fix car bumpers on them for easy processing by workers. However, the current positioning structure is fixed and can only position car bumpers of a certain size. It cannot position and clamp car bumpers of different sizes, resulting in a limited range of applications. Therefore, a painting fixture for car bumpers is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a painting fixture for car bumpers, which has advantages such as improving the applicability of the painting fixture. It solves the problem that the positioning structure is fixed and can only position car bumpers of a certain size, and cannot position and clamp car bumpers of different sizes, resulting in a limited range of applications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a painting fixture for an automobile bumper, comprising a support platform, a support base, and a worktable, wherein the top of the support platform is provided with an adjustment structure;

[0006] The adjustment structure includes a fixed support platform fixedly installed on the top outer wall of the workbench. A fixed frame is fixedly installed on the top outer wall of the fixed support platform. A first bidirectional threaded rod is rotatably connected to the inner wall of the fixed frame. Two adjustment seats are threadedly connected to the outer peripheral wall of the first bidirectional threaded rod. Mounting plates are fixedly installed on the left and right outer walls of the adjustment seats. A movable support platform is fixedly installed between two adjacent mounting plates. A longitudinal fixed clamping plate is fixedly installed on the top outer wall of the movable support platform.

An electric telescopic rod is fixedly installed on the top outer wall of the mounting frame. A top clamping plate is fixedly installed on the telescopic shaft of the electric telescopic rod. A rubber plate is fixedly installed on the top outer wall of the top clamping plate. A second bidirectional threaded rod is rotatably connected between the left and right inner walls of the mounting frame. Two movable seats are threadedly connected to the outer peripheral wall of the second bidirectional threaded rod. A movable clamping plate is fixedly installed on the front outer wall of the movable seat. A limit rod is fixedly installed between the left and right inner walls of the mounting frame.

[0007] Furthermore, a rubber vibration damping base is fixedly installed on the bottom outer wall of the support platform, and the bottom of the rubber vibration damping base is at the same height as the bottom of the support platform.

[0008] Furthermore, the adjusting seat and the mounting plate are respectively provided with threaded holes and through holes. The first bidirectional threaded rod is threadedly connected to the inside of the threaded hole and is adapted in size. The first bidirectional threaded rod is slidably connected to the inside of the through hole and is adapted in size.

[0009] Furthermore, the outer walls of the two longitudinal fixed clamps on opposite sides and the outer walls of the two movable support platforms on opposite sides are located on the same plane.

[0010] Furthermore, the top clamping plate and the rubber plate are slidably connected between the inner walls of the left and right sides of the mounting frame, and the rubber plate is located directly above the longitudinal fixing clamping plate and the transverse positioning plate.

[0011] Furthermore, the movable seat has a sliding hole inside, and the limiting rod is slidably connected inside the sliding hole and is of a suitable size. The bottom of the movable clamp is at the same height as the top of the fixed support platform, and the fixed support platform is at the same height as the movable support platform.

[0012] Furthermore, the support base is fixedly installed at the bottom of the support platform, and the workbench is fixedly installed at the top of the support platform.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The painting fixture for this car bumper uses a first bidirectional threaded rod, an adjusting seat, and a mounting plate to adjust the position of the movable support platform left and right, allowing for adjustment according to different sizes of car bumpers. The second bidirectional threaded rod, the movable seat, and the limiting rod enable the movable clamping plate to also adjust according to the position of the movable support platform. This allows the movable clamping plate and the longitudinal fixed clamping plate to hold and fix the car bumper, improving its applicability to different sizes of car bumpers. Simultaneously, the electric telescopic rod, the top clamping plate, and the rubber plate enhance the stability of the clamping and fixing process. Attached Figure Description

[0031] The distance between the two movable support platforms 9 is adjusted according to the size of the car bumper. First, the first bidirectional threaded rod 6 is rotated, and the two movable support platforms 9 will move towards each other or away. After the movable support platforms 9 are adjusted, the car bumper is placed on top of the fixed support platform 4 and the movable support platform 9. Then, the second bidirectional threaded rod 16 is rotated, which drives the movable clamping plate 18 to move through the movable seat 17. The movable clamping plate 18 will move towards the car bumper, and the car bumper will be clamped and fixed by the longitudinal fixed clamping plate 10 and the movable clamping plate 18. Finally, the electric telescopic rod 13 is activated, which drives the top clamping plate 14 and the rubber plate 15 to move downward and clamp the top of the car bumper. At this time, the car bumper clamping and positioning work is completed.
