During the painting process, there is no need to adjust the painting position, allowing for even painting of the parts and improving work efficiency. The specific details are as follows: 1. When painting the workpiece, the accessory can be placed on top of the placement plate. Turning the handwheel drives the threaded rod, causing the two movable plates to move closer together synchronously. The movement of the movable plates clamps and fixes the accessory in the middle of the two rotating plates. Then, the electric push rod can move the movable plate away from the placement plate, causing the mounting plate to move. After the mounting plate moves, the column slides in the guide groove, causing the placement plate to move downwards. At this point, the movable frame is moved to its limit position. Depending on the size of the accessory, turning the knob drives the screw to rotate. The screw rotation moves the movable block, which in turn moves the rotating block. The rotating block then moves... The device can move the movable frame to the side above the parts, then close the door, causing the servo motor to drive the rotating plate to rotate, making the parts rotate. Through the external pump, paint can be delivered to the connecting pipe for painting. The stepper motor can be started to drive the rotating block on the rotating frame to rotate circumferentially. The circumferential rotation of the rotating block can drive the movable frame to move back and forth through the connection with the sliding groove, causing the paint sprayer to move back and forth, which can evenly paint the parts. When painting automotive parts, the painting range can be adjusted according to the size of the parts, and the painting position does not need to be adjusted during the painting process. The parts can be painted evenly, improving work efficiency. 2. When painting the parts, the box door can be closed. The paint box can protect the paint from flying paint onto the outside environment and prevent pollution of the working environment. When painting evenly, the movable frame moves the paint hood back and forth. The movement of the paint hood will pull the connecting pipe, which can make the spherical part rotate on the paint box. At the same time, the connecting pipe slides on the spherical part and stretches the telescopic spring. The movable frame can be reset by the telescopic spring, which can drive the connecting pipe to reset. This can prevent the connecting pipe from getting tangled or knotted when the movable frame moves back and forth to paint. Attached Figure Description

[0020] Working principle: Before using this protective automotive parts painting device, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 4As shown, when painting the workpiece, the accessory can be placed on top of the placement plate 108. Turning the handwheel drives the threaded rod 106 to rotate, causing the two movable plates 103 to move closer together synchronously. The movement of the movable plates 103 clamps and fixes the accessory to the middle of the two rotating plates 104. Then, the electric push rod 110 moves the movable plate 111 away from the placement plate 108, causing the mounting plate 113 to move. After the mounting plate 113 moves, the column rod 115 slides in the guide groove 114, causing the placement plate 108 to move downwards. At this point, the movable frame 203 is moved to its limit position. Depending on the size of the accessory, the knob can be turned to rotate the screw 205. The rotation of the screw 205 moves the movable block 206, which in turn moves the rotating block 207. When the rotating block 207 moves, it can push the movable frame 203 to move, so that the movable frame 203 moves to the side above the part. Then the box door 102 can be closed, so that the servo motor 105 drives the rotating plate 104 to rotate, so that the part rotates. Paint can be delivered to the connecting pipe 212 through the external pump body, so that the part can be sprayed. The stepper motor 201 is started to drive the rotating block 207 on the rotating frame 202 to rotate circumferentially. The circumferential rotation of the rotating block 207 can drive the movable frame 203 to move back and forth through the connection with the sliding groove 208, so that the paint spraying cover 211 moves back and forth, so that the part can be sprayed evenly. When spraying automotive parts, the spraying range can be adjusted according to the size of the part. There is no need to adjust the spraying position during the spraying process. The part can be sprayed evenly, improving work efficiency. When painting the parts, the box door 102 can be closed. The paint box 101 can protect the paint from flying paint to the outside during the painting process, thus avoiding pollution of the working environment. When painting evenly, the movable frame 203 drives the paint spray cover 211 to move back and forth. The movement of the paint spray cover 211 will pull the connecting pipe 212 to move, which can drive the spherical part 213 to rotate on the paint box 101. At the same time, the connecting pipe 212 slides on the spherical part 213 and stretches the telescopic spring 214. The movable frame 203 can be reset by the telescopic spring 214, which can drive the connecting pipe 212 to reset. This prevents the connecting pipe 212 from becoming too long and getting tangled or knotted when the movable frame 203 moves back and forth to paint.
