Description

Technical Field

[0001] This utility model relates to the field of automotive parts painting technology, specifically an adjustable hanging bracket for automotive parts painting. Background Technology

[0002] Automotive parts painting is an indispensable key process in the automotive manufacturing and repair industry. It uses specific coating materials as a medium and professional spraying equipment to evenly cover the surface of automotive parts with coatings. After curing, it forms a continuous and dense protective film or decorative layer. This process not only directly determines the appearance and texture of automotive parts, but also has a decisive impact on their performance such as corrosion resistance and wear resistance. It is an important link in improving the competitiveness and service life of automotive products.

[0003] Current hanging racks generally lack stable and precise lifting and adjustment mechanisms, and most can only fix the workpiece at a single height for spraying operations. Due to the differences in size and specifications of different types of automotive parts, and the strict requirements of the spraying process on the distance between the spray gun and the workpiece surface, the fixed-height hanging method cannot meet the diverse process needs. Workers cannot flexibly adjust the workpiece height according to the actual spraying area, resulting in inaccurate control of the distance between the spray gun and the workpiece surface. This often leads to uneven paint adhesion, with some areas having excessively thick paint that causes runs, while other areas are under-sprayed, seriously affecting the appearance consistency and protective performance of the parts. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable hanging bracket for painting automotive parts, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hanging bracket for painting automotive parts, comprising a support bracket, a drive motor fixed to the top of the support bracket, a linkage rotating rod fixed to one end of the output shaft of the drive motor, a lifting component fixed to one end of the linkage rotating rod, a limiting component fixed to the bottom outer wall of the lifting component, an adjusting plate rotatably mounted at the bottom end of the limiting component, a cavity opened inside the adjusting plate, a drive screw rotatably mounted inside the cavity, a sliding block threaded on the outer wall of the drive screw, a clamping vertical rod fixed to the bottom end of the sliding block, and a movable clamping plate fixed to the inner side of the bottom end of the clamping vertical rod.

[0006] Preferably, multiple rubber pads are fixed side by side on the inner end face of the movable clamping plate, thereby preventing the movable clamping plate from damaging the workpiece.

[0007] Preferably, the sliding block has a through hole inside, and the through hole is provided with a thread that matches the outer wall of the drive screw, so that the sliding block can be moved by the thread transmission principle.

[0008] Preferably, the lifting component includes a drive turntable, one end of the linkage rod is fixed to the drive turntable, one side end face of the drive turntable is fixed to a limit crossbar, the outer wall of the limit crossbar is slidably provided with a lifting groove, and the bottom end of the lifting groove is fixed to a linkage vertical rod.

[0009] Preferably, the bottom end of the support bracket is provided with a support bend rod, one end of which is fixed with a limiting ring. The limiting ring is sleeved on the outer wall of the lifting vertical rod, thereby limiting the movement stroke of the lifting vertical rod.

[0010] Preferably, the limiting component includes a limiting horizontal plate, the limiting horizontal plate is fixed to the outer wall of the linkage vertical rod, a sliding plate is slidably provided on the bottom outer wall of the linkage vertical rod, a limiting insert rod is fixed to the bottom end of the sliding plate, and a limiting groove plate is fixed to the bottom outer wall of the linkage vertical rod.

[0011] Preferably, a spring is fixed to the bottom end of the limiting plate. The spring is a return spring, and the other end of the return spring is fixed to the top end of the sliding plate. The elasticity of the return spring can drive the sliding plate to return to its original position.

[0012] Preferably, the sliding plate has a limiting groove inside that matches the limiting block on the outer wall of the linkage vertical rod, thereby limiting the sliding plate.

[0013] Preferably, the outer wall of the limiting groove plate has a through hole, which, together with the limiting rod, can limit the adjustment plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The device, through the power transmission of a drive motor, a linkage rod, and a drive turntable, combined with the sliding engagement of a limit crossbar and a lifting slide, can stably adjust the vertical linkage rod and the clamped workpiece. Operators can precisely control the height of the workpiece according to the spraying process requirements, maintaining the optimal distance between the spraying area and the spray gun, effectively improving the uniformity of paint adhesion. The design of the limiting component enables flexible adjustment of the workpiece angle. By moving the sliding plate upward, the limiting rod can be released from the limiting plate. Rotating the adjusting plate can turn the uncoated surface of the workpiece to the operating side. After adjustment, the reset spring drives the limiting rod to automatically engage and limit the workpiece. The whole process is convenient and efficient. This angle adjustment function ensures that all surfaces of the workpiece can be fully coated, completely solving the problem of coating dead angles caused by traditional fixed hanging, and improving the comprehensiveness and consistency of workpiece coating.
