[0035] Specifically in the present embodiment, the drilling process is divided into four steps, namely installation, drilling, subsequent processing and automatic disassembly, which are completed by the cooperation between the circular working groove, the positioning device 5, the incomplete gear 23 and the driving motor 22. The working process corresponding to the circular working groove on the far left is installation; the mechanical accessories are inserted into the auxiliary clamping assembly 52, and the mechanical accessories are clamped by the auxiliary clamping assembly 52 to increase their stability during drilling, and then the incomplete gear 23 is driven by the driving motor 22 to rotate one circle, so that the installation shaft 2 drives the installation circular plate 3 to rotate 1 / 4 circle, so that the mechanical accessories after installation are transported to the bottom of the drilling mechanism for drilling; after the drilling is completed, the driving motor 22 continues to drive the installation circular plate 3 to rotate 1 / 4 circle, so that the mechanical accessories after drilling are transported to the far right for subsequent processing, such as spraying, etc.; when the subsequent processing is completed, the driving motor 22 continues to drive the installation circular plate 3 to rotate 1 / 4 circle, so that the driving rack 57 The lower end is in contact with the push plate 58, and the push plate 58 pushes the driving rack 57 to move upward.
