[0002] With the continuous innovation of modern manufacturing and material repair technologies, the comprehensive and intelligent requirements of industrial production for material repair and surface treatment processes are increasing day by day. Material surface repair usually includes coating preparation and post-treatment steps. Coating preparation includes electroplating processes such as electro-brush plating, and post-treatment includes treatment methods such as grinding. In traditional repair processes, electro-brush plating and grinding processes are often regarded as two independent treatment links. For example, independent electro-brush plating equipment and grinding devices are used, and electro-brush plating and grinding operations are carried out on corresponding equipment and workstations respectively. When facing complex and diverse workpiece repair requirements, due to the separation of processes and the lack of necessary linkage and information interaction between equipment, there are often problems of positioning errors and poor process connection between the electro-brush plating and grinding links during continuous maintenance, thus affecting the surface repair quality and service life of workpieces. In the multi-station operation mode, the layout of each equipment is relatively fixed and lacks flexibility, and it cannot be quickly adjusted and optimized according to different workpiece sizes, shapes and repair requirements, which severely restricts the overall maintenance efficiency and accuracy in a large-scale production environment.

[0003] There is still a large room for improvement in the existing technology in terms of improving the repair quality of workpieces, shortening the process cycle and reducing production costs. It is necessary to develop a multi-station coating preparation and post-treatment collaborative repair test device to realize the organic integration and collaborative operation of electro-brush plating and grinding processes, achieve high-precision and multi-degree-of-freedom operations in a limited working space, and greatly improve the workpiece repair efficiency.

[0038] When the first drive shaft 43 rotates, the drive disk 44 rotates. The spiral groove 441 cooperates with the tooth part 421 of the jaw 42, driving multiple jaws 42 on the chuck 4 to approach or move away from the center of the chuck 4 synchronously. When multiple jaws 42 approach the center of the chuck 4 simultaneously, the workpiece is clamped; when multiple jaws 42 move away from the center of the chuck 4 simultaneously, the workpiece is released.

Wherein, one end of the first universal joint 52 is fixedly connected to the upper end of the telescopic rod 51, and the other end of the first universal joint 52 is fixedly connected to the first drive shaft 43.

[0040] Refer to Figure 5 The telescopic rod 51 includes a telescopic inner rod 511 and a telescopic sleeve 512 that are slidably sleeved. To prevent relative rotation between the telescopic inner rod 511 and the telescopic sleeve 512 during the telescopic process of the telescopic rod 51, a convex block is fixedly arranged on the outer peripheral wall of the telescopic inner rod 511, and a long groove for the convex block to slide is provided on the side wall of the telescopic sleeve 512.

[0057] Further, refer to Figure 13, a vibration driving member is installed on the vibration seat 82 for driving the vibration seat 82 to reciprocate vertically, and a vibration adjusting assembly for adjusting the amplitude of the vibration seat 82 is provided on the vibration driving member. Specifically, the vibration driving member is the fourth motor 86, and the vibration adjusting assembly is a fixed eccentric block 87 and an adjustable eccentric block 88 fixedly connected to the output end of the fourth motor 86, and the angle between the adjustable eccentric block 88 and the fixed eccentric block 87 can be adjusted.

[0058] During the electro-brush plating process, the fourth motor 86 drives the fixed eccentric block 87 and the adjustable eccentric block 88 to rotate, thereby driving the vibration seat 82 to reciprocate vertically, which helps to reduce the defects caused by uneven deposition during the plating process, improve the density and uniformity of the coating, and at the same time enhance the bonding force and surface quality of the coating.

[0059] By adjusting the angle between the adjustable eccentric block 88 and the fixed eccentric block 87, the amplitude of the vibration seat 82 can be adjusted to adapt to different processing requirements; when the convex parts of the adjustable eccentric block 88 and the fixed eccentric block 87 face the same direction, the amplitude is the largest; when the convex parts of the adjustable eccentric block 88 and the fixed eccentric block 87 face the opposite direction, the amplitude is the smallest; by adjusting the rotation speed of the fourth motor 86, the vibration frequency of the vibration seat 82 can be adjusted.

[0060] Refer to Figure 13 , a second connecting plate 89 is fixedly connected to the vibration seat 82, and the second connecting plate 89 is fixedly connected to the mounting frame 71. Refer to Figure 14 , a horizontal fourth guide rail 741 is fixedly provided on the mounting frame 71, two transverse sliding seats 742 are slidably provided on the fourth guide rail 741, and a grinding machine and an electro-brush plating anode are installed on each transverse sliding seat 742. Correspondingly, the transverse adjusting assembly 74 is also provided in two groups for adjusting the positions of the two transverse sliding seats 742 respectively.

[0061] Refer to Figure 14 , the transverse adjusting assembly 74 includes a second displacement adjusting screw 743 rotatably provided on the side of the mounting frame 71. The second displacement adjusting screw 743 includes a screw rod threadedly connected to the mounting frame 71. A convex ring is fixedly provided at one end of the screw rod, and a limiting groove for accommodating the convex ring is provided on one side of the transverse sliding seat 742. By turning the second displacement adjusting screw 743, the transverse sliding seat 742 can be pushed to move.

[0062] Through the cooperation of the transverse adjusting assembly 74, the multi-stage telescopic assembly 73 and the lifting assembly 72, the position adjustment of the electro-brush plating head 61 and the grinding head 62 in the three-dimensional space can be realized, so that the position of the electro-brush plating head 61 or the grinding head 62 corresponds to the position of the workpiece on the chuck 4.

[0063] Refer to Figure 11, in this embodiment, the electro-brush plating head 61 is cylindrical. During the electro-brush plating process, the side wall of the electro-brush plating head 61 contacts the surface of the workpiece, and the plating solution is transported to the surface of the electro-brush plating head 61 through the plating solution circulation pump 63. Refer to Figure 9 , a circular plating solution collecting groove 311 is fixedly arranged on the mounting base 31. The plating solution collecting groove 311 is located below the chuck 4 and is used for collecting the excess plating solution.

[0064] The implementation principle of a multi-station coating preparation and post-treatment collaborative repair test device according to an embodiment of the present application is as follows: The present application adopts a multi-station design. Through the synchronous drive of multiple chucks 4, synchronous clamping of multiple workpieces is realized, allowing multiple workpieces to perform repair operations simultaneously; by the lifting of the lifting table 2 in the vertical direction and the sliding of the loading table 3 in the horizontal direction, the position of the chuck 4 can be adjusted. Through the cooperation of the lateral adjustment assembly 74, the multi-stage telescopic assembly 73 and the lifting assembly 72, the positions of the electro-brush plating head 61 and the grinding head 62 are adjusted to correspond to the position of the chuck 4 to meet different processing requirements; through the integrated plating and grinding setting, first use the electro-brush plating head 61 to perform electro-brush plating on the surface of the workpiece, and then use the grinding head 62 to grind the surface of the workpiece, realizing the collaborative operation of high-precision and multi-degree-of-freedom coating preparation and post-treatment processes in a limited working space, thereby improving the repair efficiency of the workpiece.

[0065] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
