Description

Technical Field

[0001] This utility model relates to the field of spray coating technology, specifically to an adjustable spray coating fixture. Background Technology

[0002] Spraying is a surface processing technology that uses specialized equipment to atomize coatings (such as paint, powder, resin, etc.) into tiny particles and uniformly adhere them to the surface of a workpiece to form a coating with specific functions (protection, decoration, insulation, etc.). As one of the core processes in industrial manufacturing and surface treatment, spraying technology is widely used in many industries such as machinery manufacturing, automotive industry, building decoration, and electronics due to its advantages such as good coating uniformity, high construction efficiency, and wide compatibility with substrates. It is a key link in improving the appearance quality and performance of products.

[0003] Most current spraying fixtures employ rigid clamping structures or manually locking clamping structures. Rigid clamping structures lack elastic adjustment capabilities. When clamping workpieces of different sizes or surface shapes, uneven clamping force distribution can easily lead to pressure marks and scratches on the workpiece surface. This is especially unsuitable for thin-walled workpieces or precision parts with high surface precision requirements. The adjustment functions of traditional spraying fixtures are generally limited. On the one hand, most fixtures can only achieve coarse position adjustment in a single direction, lacking precise linear adjustment mechanisms. This makes it difficult to finely position the workpiece according to the needs of different spraying stations, resulting in incomplete spraying coverage and the need for frequent repositioning. On the one hand, moving the spraying equipment or adjusting the overall position of the fixture is cumbersome. On the other hand, for workpieces that require multi-sided spraying, existing fixtures often cannot flexibly adjust the workpiece angle. Operators usually need to remove the workpiece from the fixture and re-clamp it, which not only increases labor intensity, but also easily leads to the accumulation of workpiece positioning errors due to repeated clamping, affecting the connection accuracy of spraying on each side and making it difficult to guarantee the quality of all-round spraying. Some fixtures with angle adjustment functions have complex adjustment structure designs and often use multiple sets of bolts for positioning and fixing. During the adjustment process, it is necessary to repeatedly disassemble and tighten the bolts, resulting in low adjustment efficiency and difficulty in guaranteeing the angle positioning accuracy. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable spray coating fixture 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 spraying fixture, comprising a crossbeam and a supporting vertical rod, wherein the supporting vertical rod is fixed to the bottom end of the crossbeam, and a cavity is formed inside the supporting vertical rod, wherein a driving component rotates within the cavity, a driving gear is fixed to the outer wall of the driving component, and an adjusting component meshes with the bottom end of the driving gear, supporting rods are fixed to both sides of the supporting vertical rod, an adjusting plate is rotatably mounted on one end face of the adjusting component, a limiting crossbeam is fixed to the other end face of the adjusting plate, a telescopic connecting rod is fixed to the inner wall of the bottom end of the limiting crossbeam, and a clamping wedge plate is fixed to one end of the telescopic connecting rod.

[0006] Preferably, the inner wall of the clamping wedge plate has sliding rubber protrusions, which can increase the friction force for clamping the workpiece.

[0007] Preferably, the outer wall of the telescopic link is provided with a spring, which is a return spring. One end of the return spring is fixed to one side end face of the limiting crossbar, and the other end of the return spring is fixed to one side end face of the clamping wedge plate. The elasticity of the return spring can drive the clamping wedge plate to clamp and fix the workpiece.

[0008] Preferably, the driving component includes a driving rod, the driving rod is rotatably mounted inside the supporting vertical rod, a driving sector gear is fixed to the outer wall of one end of the driving rod, a linkage sector gear is engaged on one side end face of the driving sector gear, and a driven sector gear is engaged on the other side end face of the linkage sector gear away from the driving sector gear.

[0009] Preferably, the adjusting component includes a sliding rack, the bottom end of the driving gear meshes with the sliding rack, the two end faces of the supporting vertical rod are fixed with limit grooves, and the sliding rack slides inside the top end of the limit grooves. An adjusting vertical plate is rotatably mounted on one side of the sliding rack, and a through hole is opened inside the top end of the adjusting vertical plate, in which a limit rod slides.

[0010] Preferably, one end face of the adjusting plate is provided with multiple limiting holes, which, together with the limiting rod, can limit the adjusting plate.

[0011] Preferably, the limiting rod is T-shaped, and a spring is fixed to one end face of the T-shaped plate. The spring is a reset spring, which can drive the limiting rod to reset.

[0012] Compared with the prior art, the beneficial effects of this utility model are: A combination of a clamping wedge plate, a return spring, and a telescopic linkage forms an elastic adaptive clamping mechanism. When the workpiece is placed into the clamping area, it is quickly positioned by the inclined guide of the clamping wedge plate. After the workpiece is in place, the elastic force of the return spring drives the clamping wedge plate to automatically reset and press firmly against the workpiece surface, forming a stable clamping force. This structure eliminates the need for additional manual locking operations, simplifying the clamping process and ensuring a continuous and stable clamping force. This prevents spraying deviations caused by workpiece loosening during the spraying process. The rubber protrusions sliding on the inner wall of the clamping wedge plate can form a flexible fit with the workpiece surface during clamping. On the one hand, the high coefficient of friction of the rubber material significantly increases the clamping friction, further preventing workpiece slippage; on the other hand, it avoids pressure marks or scratches on the workpiece surface caused by rigid clamping. This is especially suitable for sprayed workpieces with high surface precision requirements, effectively ensuring the workpiece processing quality. The device constructs a linear adjustment mechanism through the transmission cooperation of a drive rod, a sector gear set, a drive gear, and a sliding rack. Rotating the drive rod causes the sliding rack to move smoothly along the limiting groove, and then the adjusting plate, which holds the workpiece, is driven by the adjusting vertical plate to achieve fine-tuning of the position. This adjustment method has a stable transmission ratio and can accurately control the horizontal position of the workpiece to meet the positioning requirements of different spraying stations. The rotating connection structure between the adjusting plate and the adjusting vertical plate, combined with the positioning design of the "T"-shaped limiting rod and multiple sets of limiting holes, realizes the angle adjustment function of the workpiece. When different sides of the workpiece need to be sprayed, simply pull the limiting rod outward to release the limiting of the adjusting plate. After rotating the adjusting plate to the target angle, the limiting rod automatically inserts into the corresponding limiting hole under the action of the return spring to complete the positioning. This design allows the workpiece to be fixed at multiple angles without frequent disassembly and reassembly of the workpiece, thus completing all-round spraying and greatly improving the flexibility and integrity of the spraying operation.
