The fixing mechanism 4 includes: a clamping plate 41 for clamping the automobile wheel hub 6, a driving assembly 42 for driving the clamping plate 41 to move, and a resetting assembly 43 for driving the clamping plate 41 to reset after the clamping is completed; the driving assembly 42 includes: a linkage plate 422 movably installed in the inner cavity of the U-shaped plate 3, a limiting member for limiting the linkage plate 422 during the movement, a power source 421 for driving the linkage plate 422 to move, a fixing rod 423 fixedly installed at the bottom center of the linkage plate 422, and a fixing pipe fixedly installed at the bottom end of the fixing rod 423. 424, a rolling member 425 rotatably mounted on the inner wall of the fixed tube 424, and a linkage member of the linkage clamping plate 41; the linkage member includes: a cylinder 426 rotatably mounted on the side wall of the mounting seat 2, a circular plate 427 that rotates with the rotation of the cylinder 426, a guide groove provided on the side wall of the circular plate 427, a limiting groove provided on the top of the mounting seat 2, a linkage rod 428 installed through the inner cavity of the guide groove and the limiting groove, and a connecting plate 429 fixedly mounted on the top of the linkage rod 428, and the connecting plate 429 is fixedly connected to the clamping plate 41.

When the automobile wheel hub 6 is clamped and fixed, the automobile wheel hub 6 is placed on the top of the mounting seat 2 and sleeved on the outer side of the clamping plate 41. At this time, by starting the power source 1 421, the linkage plate 422 can be driven to move downward, the linkage plate 422 drives the fixing rod 423 to move downward, the fixing rod 423 drives the fixing tube 424 to move downward, and the fixing tube 424 drives the rolling element 425 to move downward;

Since the edge of the cylinder 426 is provided with a guide groove, the guide groove is composed of a vertical groove and a spiral groove, and the vertical groove and the spiral groove are mutually interpenetrating, at this time, the rolling member 425 first moves downward along the vertical groove, so that the fixed tube 424 is sleeved on the outside of the cylinder 426, and then the rolling member 425 enters the inner cavity of the spiral groove. Since the moving direction of the rolling member 425 is vertically downward, the rolling member 425 can drive the cylinder 426 to rotate during the movement of the inner cavity of the spiral groove, and the cylinder 426 drives the circular plate 427 to rotate. Under the guiding action of , the connecting rod 428 can be driven to move, and under the limiting action of the limiting groove, the connecting rod 428 keeps moving in a straight line direction, so that the rotation of the circular plate 427 can drive the connecting rod 428 to move in the direction close to the inner wall of the automobile wheel hub 6, thereby driving the connecting plate 429 to move, and the connecting plate 429 drives the clamping plate 41 to move, so that the inner wall of the automobile wheel hub 6 can be clamped and fixed, preventing the automobile wheel hub 6 from moving during the spraying process, affecting the spraying effect, and improving the stability of the spraying.

In addition, four groups of clamping plates 41 are provided to clamp and fix the automobile wheel hub 6 from different directions, thereby improving the stability of the fixation.

It is added here that the power source 421 is preferably: a cylinder, which can easily drive the linkage plate 422 to move up and down; the rolling element 425 is preferably: a bull's eye ball, which can better slide in the inner cavity of the guide groove.

The limiting component includes: a limiting groove provided on the inner wall of the U-shaped plate 3, and a sliding bar fixedly installed on the side wall of the linkage plate 422 and sliding in the inner cavity of the limiting groove; when the linkage plate 422 moves, the sliding bar can be driven to slide in the inner cavity of the limiting groove, and through the mutual cooperation between the sliding bar and the limiting groove, the linkage plate 422 can be limited when the linkage plate 422 moves, so that the linkage plate 422 has higher stability when moving.

The reset assembly 43 includes: a slide groove provided on the inner wall of the mounting seat 2, a slider 431 fixedly mounted at the bottom end of the linkage rod 428 and sliding in the inner cavity of the slide groove, a slide rod 432 for limiting the slider 431, both ends of the slide rod 432 are fixedly mounted on the inner wall of the slide groove, a reset spring 433 for driving the slider 431 to reset, one end of the reset spring 433 is fixedly mounted on the side wall of the slider 431, and the other end is fixedly mounted on the inner wall of the slide groove; when the linkage rod 428 moves, the slider 431 can be driven to slide in the inner cavity of the slide groove, thereby driving the reset spring 433 to deform. When the automobile wheel hub 6 is sprayed and it is no longer necessary to clamp and fix the automobile wheel hub 6, the elastic force of the reset spring 433 is used to reset the clamping plate 41 to the initial position, thereby preparing for the next use.

After the automobile wheel hub 6 is fixed, it is necessary to transport the coating material to the nozzle 51 through the conveying component 52 to spray the automobile wheel hub 6. At this time, the telescopic tube 1 522 is first docked with the nozzle 51, that is, by starting the power source 2 523, the movable plate 1 524 can be driven to move downward, and the movable plate 1 524 drives the telescopic tube 1 522 to move downward, and drives the rack 1 525 to move downward, and then drives the protection component 56 to operate. Through the mutual cooperation with the protection component 56, the docking of the telescopic tube 1 522 and the nozzle 51 can be completed. After the docking of the telescopic tube 1 522 and the nozzle 51 is completed, by starting the pump body 1, the coating material in the inner cavity of the coating material box 521 can be sucked and enter the nozzle 51 through the telescopic tube 1 522, and the coating material is sprayed out through the nozzle 51, thereby realizing that the coating material can be automatically transported to the nozzle 51 when spraying the automobile wheel hub 6;

When the nozzle 51 is not in use, the nozzle 51 is located in the inner cavity of the protective shell 561, and the nozzle 51 is inserted into the side wall of the movable plate 563, so that it can move with the movement of the movable plate 563. The top of the connecting pipe 57 can be closed by the protective plate 1 562, and the bottom of the protective shell 561 can be closed by the protective plate 2 564. Through the mutual cooperation of the protective shell 561, the protective plate 1 562, and the protective plate 2 564, the nozzle 51 can be protected to prevent dust from entering the inner cavity of the nozzle 51 when the nozzle 51 is not in use, causing the nozzle 51 to be blocked and affecting the spraying effect.

The linkage unit 565 includes: a threaded block 5654 fixedly mounted on one side of the protective plate 1 562, a threaded strip 5656 fixedly mounted on one side of the protective plate 2 564, a positioning rod penetrating the side wall of the threaded strip 5656, both ends of the positioning rod are fixedly mounted on the inner wall of the protective shell 561, and the threaded strip 5656 can be positioned when it moves by setting the positioning rod to prevent the threaded strip 5656 from rotating with the bidirectional screw 5653, a movable rod 5657 hingedly mounted on one side of the movable plate 563, a threaded block 2 5655 hingedly mounted on one end of the movable rod 5657, and a threaded block 1 565 4. The threaded rod 1 5651 is movable, a linkage gear 5658 is fixedly installed at one end of the threaded rod 1 5651, a bidirectional screw 5653 is driven to move the threaded strip 5656, a threaded rod 2 5652 is driven to move the threaded block 2 5655, and a transmission member 5659 is driven to synchronously rotate the threaded rod 1 5651, the threaded rod 2 5652, and the bidirectional screw 5653; the transmission member 5659 includes: a pulley 56591 is fixedly installed at one end of the threaded rod 1 5651, the threaded rod 2 5652, and the bidirectional screw 5653, and a linkage belt 56592 is installed between the pulleys 56591.

As an optional solution: the transmission member 5659 can adopt chain drive to avoid the problem of belt transmission slipping. The belt can also be tensioned by a tensioning wheel to increase the belt's wrap angle to avoid the problem of belt transmission slipping.

Since there are two threaded rods 1 5651 and two threaded rods 2 5652, and the thread directions of the two threaded rods 1 5651 are opposite, the thread directions of the two sets of threaded rods 2 5652 are opposite, and the threaded rod 1 5651 rotates to drive the two threaded blocks 1 5654 away from each other, and the two threaded blocks 1 5654 drive the adjacent protective plates 1 562 away from each other, so that the two protective plates 1 562 release the sealing of the top of the connecting pipe 57. At the same time, the bottom end of the telescopic tube 1 522 moves downward and is inserted into the inner cavity of the connecting pipe 57, thereby realizing the docking of the telescopic tube 1 522 with the connecting pipe 57, and then realizing the docking of the telescopic tube 1 522 with the spray head 51. When the docking of the telescopic tube 1 522 with the spray head 51 is completed, the coating material in the inner cavity of the coating material box 521 can be sucked and enter the spray head 51 through the telescopic tube 1 522 by starting the pump body 1, and the coating material is sprayed out through the spray head 51, thereby realizing the spraying work of the automobile wheel hub 6;

By rotating the bidirectional screw 5653, the two threaded strips 5656 can be driven away from each other, and then the two protective plates 564 can be driven away from each other, so that the two protective plates 564 do not have a sealing effect on the bottom of the protective shell 561. At the same time, the two threaded blocks 5655 are driven closer to each other through the threaded rod 5652, and the two threaded blocks 5655 drive the adjacent movable rods 5657 closer to each other, so that the movable plate 563 can be pushed to move downward, and the nozzle 51 is driven downward by the movable plate 563, so that the nozzle 51 moves to the outside of the protective shell 561, so as to facilitate the nozzle 51 to spray.

When the telescopic tube 2 552 is connected to the nozzle 51, the pump body 2 is started to absorb the cleaning agent in the cleaning agent box 551 and transport it to the nozzle 51 through the telescopic tube 2 552, so that the residual coating in the nozzle 51 can be rinsed clean, thereby achieving the cleaning process of the replaced nozzle 51, avoiding the residual coating in the nozzle 51 from solidifying easily, causing uneven spraying, and affecting the subsequent spraying effect. A collection box is provided on the top of the mounting seat 2, and the collection box is located directly below the cleaning component 55, so that the waste liquid generated by the cleaning of the nozzle 51 can be collected.

It should be added here that the power source five 553 is preferably: a cylinder, so as to facilitate the movement of the movable plate two 554 up and down.

By cooperating with the adjustment component 54 and the cleaning component 55, the nozzle 51 can be automatically replaced without manual replacement, thereby improving the replacement efficiency. The replaced nozzle 51 can also be cleaned, thereby preventing the residual coating in the nozzle 51 from solidifying easily and causing uneven spraying, thereby ensuring the subsequent spraying effect and improving the spraying quality of the automobile wheel hub 6.
