The workers' work intensity is high and the grinding speed is slow, which makes it difficult to meet the requirements of modern industrial production for high efficiency. This inefficient treatment method often leads to a long production cycle, affecting the overall production progress and delivery time. The quality of manual grinding is highly dependent on the workers' technical level and experience, and there is a large degree of instability.

A gap is provided between the outer surface of the return pipe 120 and the inner wall surface of the bottom recovery pipe 131 , through which the grinding sand can pass. A splash plate 118 is fixed on the reinforcement frame 117 to prevent the grinding sand ejected from the injection nozzle 119 from splashing out.

[0016] The working principle of a high-hardness alloy surface repair system disclosed in the present invention is as follows: alloy parts with the same parameters that need to remove scratches are placed on the support platform plate 133 corresponding to the support plate 129. According to the size of the alloy parts, the distance between the support plate 129 and the injection nozzle 119 can be adjusted so that the distance between the surface of the alloy part that needs to remove scratches and the injection nozzle 119 is as close as possible. Specifically, the adjustment sliding tube 128 is controlled to slide on the support shell 123. The movement of the adjustment sliding tube 128 can be controlled by rotating the adjustment screw 126. This is because the adjustment sliding tube 128 is threadedly matched with the adjustment screw 126. Only one of the adjustment screws 126 needs to be rotated with a hexagonal wrench, and the rotating adjustment screw 126 will drive the other adjustment screw 126 to rotate through the adjustment synchronization gear 127, so that the two adjustment sliding tubes 128 move synchronously.

[0017] After adjusting the position of the alloy parts, the main drive motor 103 and the auxiliary synchronous motor 114 are started, wherein the output shaft of the main drive motor 103 drives the driving gear 104 to rotate, the driving gear 104 drives the driving toothed disc 105 to rotate, the driving toothed disc 105 drives the input shaft of the planetary gearbox 102 to rotate, the input shaft of the planetary gearbox 102 drives the synchronous pulley 108 to rotate through the second transmission belt 107, the synchronous pulley 108 drives the downward pressure rotating cylinder 111 to rotate, the downward pressure rotating cylinder 111 drives the rotating injection tube 122 to rotate, at this time the grinding sand inside the rotating injection tube 122 will rotate, the grinding sand will be subjected to centrifugal force when rotating, at this time the grinding sand is subjected to centrifugal force It will be ejected through the slit groove on the injection nozzle 119, and the grinding sand will be ejected onto the surface of the alloy part. The high-speed flowing grinding sand will remove the scratches on the surface of the alloy part. In order to ensure the synchronization of the alloy part and the jet ejected by the injection nozzle 119, the output shaft of the auxiliary synchronous motor 114 will drive the rotating ring frame 116 to rotate through the third transmission belt 115, and the rotating ring frame 116 will drive the reinforcing frame 117 to rotate. The reinforcing frame 117 will drive all the supporting parts to rotate. At this time, the alloy parts on the supporting parts will follow the rotation to keep the synchronous rotation of the injection nozzle 119 and the alloy parts. The alloy parts will also be subjected to centrifugal force during the rotation process, so that the alloy parts are more closely attached to the support plate 129. A counterweight block is arranged inside the support shell 123, and its purpose is to ensure the dynamic balance of the alloy parts during the rotation process and reduce vibration.

[0018] The grinding sand ejected from the injection nozzle 119 will fall into the bottom recovery cone pool 113, and then slide along the bottom recovery cone pool 113 to the bottom recovery pipe 131. Because the output shaft of the planetary gearbox 102 will drive the return screw 121 to rotate through the first transmission belt 106, the rotation of the return screw 121 will discharge the grinding sand inside the bottom recovery pipe 131 into the return pipe 120, and then the grinding sand moves along the return pipe 120 to the downward pressure rotating cylinder 111, thereby replenishing the grinding sand flowing out of the downward pressure rotating cylinder 111 to ensure that there is always grinding sand in the downward pressure rotating cylinder 111 and the rotating injection tube 122.

[0019] By controlling the rotation speed of the auxiliary synchronous motor 114 and the main drive motor 103, the rotation difference between the injection nozzle 119 and the alloy part can be controlled. The rotation difference can align the slit groove on the injection nozzle 119 with different positions on the surface of the alloy part, thereby repairing scratches at different positions on the surface of the alloy part.
