During operation, it is very important to fix the workpiece during spraying or painting. By fixing the workpiece, the spraying or painting equipment can be operated at the correct position and angle to ensure that the paint or spray agent evenly covers the surface of the workpiece, which can avoid uneven coating thickness or quality and enhance the consistency and appearance quality of the coating. The threaded rod 35 is rotated by the rotating disk 36 to rotate the threaded rod 35. When the threaded rod 35 rotates, the connecting ring 37 rotates. When the connecting ring 37 rotates, it moves up and down along the direction of the threaded rod 35.

During operation, if the spray gun or nozzle is held at an incorrect angle, that is, not perpendicular to the target surface or not parallel to it, it may also cause paint dripping. At an incorrect angle, the paint may not be evenly attached to the target surface, thereby forming dripping. If it is not handled in time, it will pollute the working environment. After the processing is completed, by opening the one-way valve 42, the paint dripping in the groove 40 will pass through the discharge pipe 41 and be discharged to the outside, so that liquid or waste can be discharged conveniently, which can save time for cleaning and maintenance and improve the convenience and efficiency of operation.

Working principle: the gear 19 will rotate when the driving motor 21 is started. The gear 19 is connected to the coupling and drives the sliding plate 23 to slide along the side groove 22. The rack 24 on the sliding plate 23 meshes with the gear 19, thereby realizing the power transmission of the sliding plate 23.

When the electrode 28 contacts the electric sheet 29, the driving motor 21 stops driving and completes the fixation of the workpiece. It can stop applying pressure to the workpiece in time to prevent excessive clamping, and can maintain the original shape and structural integrity of the workpiece. In order to avoid deformation problems caused by clamping, it is very important to fix the workpiece during the spraying or painting process. By fixing the workpiece, the spraying or painting equipment can be operated at the correct position and angle to ensure that the paint or spray agent evenly covers the surface of the workpiece. This can avoid uneven coating thickness or quality and enhance the consistency and appearance quality of the coating. The threaded rod 35 is rotated by the rotating disk 36 to rotate the threaded rod 35. When the threaded rod 35 rotates, the connecting ring 37 rotates. When the connecting ring 37 rotates, it moves up and down along the direction of the threaded rod 35. When the connecting ring 37 moves up and down, the slider 32 can be moved along the guide Sliding in the direction of the rod 31 can shorten or lengthen the distance between the two clamping plates 34, and can also fix the workpiece, which can ensure that the workpiece maintains a stable position during the spraying process. The stable position allows the sprayed paint to evenly cover the surface of the workpiece, reducing the risk of uneven coating and wrinkling. The fixture in the prior art cannot flip the processed workpiece and cannot control the flipping angle, which may cause the sprayed material to not evenly cover the surface of the workpiece, and some parts may be sprayed too much or too little, resulting in uneven coating thickness, affecting the spraying effect and quality. By turning the handle 6, the support rotating disk 5 will be driven to rotate, and the rotating column 11 will also rotate accordingly. When the rotating column 11 rotates, it will drive the fixed plate 12 to rotate. When the fixed plate 12 rotates, it will drive the pointing rod 13 and the pointing needle 14 to slide inside the annular groove 16, so as to help determine the required processing angle of the workpiece. By rotating the knob 10, the screw 9 can enter or exit the screw hole 8, thereby fixing or releasing the position of the rotating disk 5. The workpiece can be flipped and the flipping angle can be controlled, so that the sprayed material can be evenly covered on the surface of the workpiece, so that the thickness of the coating is uniform, and the spraying effect and quality are improved. If the spray gun or nozzle is kept at an incorrect angle, that is, not perpendicular to the target surface or not parallel to it, it may also cause the paint to drip. At an incorrect angle, the paint may not be evenly attached to the target surface, thereby forming dripping. If it is not handled in time, it will pollute the working environment. After the processing is completed, by opening the one-way valve 42, the paint dripping in the groove 40 will pass through the discharge pipe 41 and be discharged to the outside, so that liquid or waste can be conveniently discharged, which can save time for cleaning and maintenance and improve the convenience and efficiency of operation.
