The three cylinders are electrically connected, and the position of the central axis of the headless screw 4 is adjusted by controlling the extension length of the top block 2052. After the headless screw 4 is initially tightened, the servo motor 203 is started to drive the headless screw 4 to rotate, and one end of the top rod 3042 is in contact with the outer wall of the headless screw 4. According to the electrical signal of the vertical pressure sensor in the telescopic sleeve 3043 at one end of the top rod 3042, the position of the central axis of the headless screw 4 is determined; In the process of clamping the headless screw 4, through the fitting of the magnetic block 2063 and the baffle 2062, one end of the headless screw 4 fits with the baffle 2062, and the magnetic block 2063 adsorbs the headless screw 4, assisting the staff to tighten the headless screw 4, and controlling the magnetism of the magnetic plate 2065 through the power coil 2066, while the spring 2064 between the magnetic block 2063 and the magnetic plate 2065 controls the spacing, and the magnetism of the magnetic plate 2065 changes through the current of the power coil 2066, and at the same time controls the position of the baffle 2062, and adjusts the horizontal position of the headless screw 4; According to the cross-sectional size of the headless screw 4, the electric slide rail 201 is started to adjust the position of the headless screw 4 on the side plate bracket 202, the servo motor 203 is started to drive the headless screw 4 to rotate, and the cutter head 303 on the linear module 301 is controlled to move horizontally at a uniform speed to open a thread on the outer wall of the headless screw 4, thereby improving the applicability of the device; After the position of the headless screw 4 is fixed, the support rod 302 is driven to move by the linear module 301, the horizontal relative position of the cutter head 303 and the headless screw 4 is adjusted, the servo motor 203 is started to drive the movable sleeve 204 to rotate, the movable sleeve 204 drives the headless screw 4 to rotate, and the cutter head 303 moves horizontally at a uniform speed through the linear module 301 to open a thread groove on the outer wall of the headless screw 4; While the outer wall of the headless screw 4 is threaded by the cutter head 303, the push rod 3042 on one side of the cutter head 303 contacts the inner wall of the thread groove formed on the headless screw 4, and the push rod 3042 scrapes the debris remaining on the inner wall of the thread groove.
