Description

Technical Field

[0001] The invention belongs to the technical field of automobile brake disc processing, and in particular relates to brake disc spraying equipment and a spraying process. Background Art

[0002] The brake disc is a key component in the automobile braking system. After the automobile brake disc is processed, the middle part of one side of the automobile brake disc and the surrounding side need to be sprayed. At present, a spraying device is often used to spray the automobile brake disc. For example, in the existing public literature, CN115646695B-an automobile brake disc spraying device is publicly provided with a support platform, a spraying mechanical arm and a support member for supporting the brake disc. A crossbeam is provided above the support platform, and the middle position of the crossbeam in the length direction is rotatably connected to the support platform. Both ends of the crossbeam in the length direction are provided with a plurality of vertical shafts, the lower end of the vertical shaft is rotatably connected to the crossbeam, a positioning block is fixedly provided at the upper end of the vertical shaft, a positioning hole is opened in the support member, and a plurality of clamping blocks are arranged along the circumferential direction at the upper end of the vertical shaft, and the clamping blocks are all hinged with the vertical shaft. When the clamping block rotates, the distance between the upper end and the positioning block changes accordingly. When the vertical shaft is located at one end of the crossbeam close to the spraying mechanical arm, the distance between the upper end of the clamping block and the positioning block is the smallest and it is tightly pressed against the side wall of the support member.

[0003] Although the above-mentioned spraying device can be used to clamp the automobile brake disc for spraying processing, during the spraying process, since the spraying area in the middle of the automobile brake disc is in a horizontal state, and the spraying area on the side of the automobile brake disc is in a vertical state, the spraying area in the middle of the automobile brake disc is thicker than the spraying area on the side of the automobile brake disc within the same spraying time, and the drying time of the spraying area in the middle of the brake disc is longer than that of the spraying area on the side of the automobile brake disc, which affects the production efficiency. Moreover, during the processing, once the spraying area in the middle of the automobile brake disc is sticky with impurities, it is easy to affect the spraying quality. In addition, during spraying, the spraying area is exposed to the outside and is easy to splash, which will not only waste the paint, but also pollute the environment, and cause the processing area to be covered with paint, which is inconvenient to clean. To this end, we provide a brake disc spraying device and a spraying process to solve the above-mentioned problems. Summary of the invention

[0042] The operation process of this embodiment is as follows: before spraying, when a set of brake discs 150 arrive at the working station, while the movable seat 240 is moved outward, the box cover 330 is immediately driven downward by the action of the hydraulic cylinders 320 on both sides, so that the box cover 330 overlaps with the collecting box 310, and the processing seat 120 at the processing station as a whole and each upper spraying assembly 270 and lower spraying assembly 280 are shielded by the box cover 330 and the collecting box 310. After the shielding is completed, the spraying operation is carried out. During the spraying process, the shielding effect is used to prevent the paint from splashing. In addition, during the spraying process, the excess paint splashed by the spraying will be collected in the collecting box 310; After the spraying operation is completed, while the movable seat 240 is moved inward, the box cover 330 is immediately driven upward through the action of the hydraulic cylinders 320 on both sides, so that the box cover 330 is away from the entire processing seat 120 and does not block the two processing seats 120 from rotating and exchanging positions.
