[0002] Spray coating is a surface treatment technology that involves uniformly applying paint to the surface of an object. When spraying irregularly shaped workpieces, which often have complex geometries, ordinary fixed fixtures are insufficient. However, adaptive spraying fixtures for irregularly shaped workpieces can adjust and adapt to their shape characteristics, ensuring uniform and precise spraying. Through ingenious positioning and support design, an adaptive clamping mechanism, and flexible adjustment and drive mechanisms, efficient and stable spraying of irregularly shaped workpieces is achieved. This fixture structure has broad application prospects in the field of spraying irregularly shaped workpieces.

[0003] However, existing adaptive spraying fixture structures have poor clamping stability when holding irregularly shaped workpieces, which makes the workpieces prone to shaking or falling during the spraying process, causing damage and affecting the processing accuracy. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides an adaptive spraying fixture structure for irregularly shaped workpieces, which has the following features:

[0016] Beneficial effects:

[0017] 1. This adaptive spraying fixture structure for irregularly shaped workpieces, through the setting of pressure components and a moving seat, places the irregularly shaped workpiece between a fixed seat and a moving seat when clamping it. Then, the drive motor is activated, causing the threaded rod to rotate at the bottom of the moving seat. This causes the moving seat to slide on the T-shaped slide rail, clamping the workpiece. For uneven surfaces, multiple sets of pressure blocks compress the workpiece surface. The elasticity of the support springs is used to adaptively compress the workpiece for protruding or recessed parts, thereby achieving a stable clamping effect for irregularly shaped workpieces and preventing them from shaking or falling during the spraying process, which would affect the processing accuracy and dimensional stability.

[0018] 2. This adaptive spraying fixture structure for irregularly shaped workpieces, through the setting of lifting components and rotating shafts, allows for the adjustment of the spraying angle by activating the output motor, which drives the rotating shaft to rotate within the rotating frame, thereby adjusting the angle of the support plate and the clamped workpiece. When the height needs to be adjusted, the hydraulic push rod is activated, which pushes the rotating frame, causing the telescopic plate to extend and retract within the support sleeve. This achieves the effect of conveniently adjusting the spraying angle and height, ensuring that the paint can evenly cover all parts of the irregularly shaped workpiece, especially those hard-to-reach corners and edges, thus improving overall flexibility.
