[0134] Working principle: When tapping is required, the worker places the workpiece to be tapped between the two clamping plates 408, and then the worker turns on the two second cylinders 407 through the controller 6. The telescopic ends of the two second cylinders 407 extend to drive the two clamping plates 408 to move toward each other until the workpiece is clamped, thereby preventing the workpiece from deviating during the subsequent tapping operation. Then the staff turns on the first motor 303 through the controller 6, the first motor 303 rotates to drive the first screw 304 to rotate, the first screw 304 rotates to drive the slider 305 to move, the slider 305 moves to drive the second motor 306 to move, the second motor 306 moves to drive the tapping head 307 and the protective box 308 to move in turn; When the second motor 306 moves, the tapping head 307 moves until the tapping head 307 moves to a designated position, preparing for subsequent tapping operations; When the second motor 306 moves to drive the protection box 308 to move, the protection box 308 moves to drive the plurality of ventilation heads 507 to move, ensuring that the plurality of ventilation heads 507 can always be aligned with the tapping head 307; Then the staff turns on the first cylinder 301 through the controller 6, and the first cylinder 301 extends downward to drive the support plate 302 to move downward, and the support plate 302 moves downward to drive the first motor 303 and the second screw 404 to move downward in turn; When the support plate 302 moves downward and drives the first motor 303 to move downward, the first motor 303 moves downward and drives the first screw 304 to move downward, the first screw 304 moves downward and drives the slider 305 to move downward, the slider 305 moves downward and drives the second motor 306 to move downward, the second motor 306 moves downward and drives the tapping head 307 and the protective box 308 to move downward in sequence; When the second motor 306 moves downward to drive the tapping head 307 to move downward, the tapping head 307 moves downward until the tapping head 307 contacts the workpiece.

When the first bevel gear 405 rotates, the second bevel gear 406 rotates, and the second bevel gear 406 rotates, which drives the outer ring of the one-way bearing to rotate. The outer ring of the one-way bearing rotates, thereby preventing the workbench 403 from rotating during the tapping operation, thereby avoiding machine failure; When the first bevel gear 405 rotates to drive the third bevel gear 503 to rotate, the third bevel gear 503 rotates to drive the fixed rod 502 to rotate, and the fixed rod 502 rotates to drive the ventilation fan 504 to rotate. The ventilation fan 504 rotates so that the outside air passes through the ventilation box 501, the ventilation pipe 505, the ventilation box 506 in sequence, and finally sprays to the tapping head 307 from the plurality of ventilation heads 507, which can effectively remove the cutting chips generated in the tapping operation and avoid the accumulation of cutting chips that leads to the deterioration of the wear quality of the tapping head 307, which helps to reduce the pause time in the processing process, thereby improving the processing efficiency. At the same time, it can reduce the temperature of the cutting area and reduce the size of the heat-affected zone, thereby reducing the wear rate of the tapping head 307; When the tapping operation is completed, the worker turns off the second motor 306 through the controller 6 and turns on the two second cylinders 407. The two second cylinders 407 contract and drive the two clamping plates 408 away from the workpiece, respectively, to facilitate subsequent unloading operations. Then the staff turns on the first cylinder 301 through the controller 6, and the first cylinder 301 contracts upward to drive the support plate 302 to move upward, and the support plate 302 moves upward to drive the first motor 303 and the second screw 404 to move upward in turn; When the support plate 302 moves upward and drives the first motor 303 to move upward, the first motor 303 moves upward and drives the first screw 304 to move upward, the first screw 304 moves upward and drives the slider 305 to move upward, the slider 305 moves upward and drives the second motor 306 to move upward, the second motor 306 moves upward and drives the tapping head 307 and the protective box 308 to move upward in turn; When the second motor 306 moves upward, it drives the tapping head 307 to move upward until the tapping head 307 is away from the workpiece, which is convenient for subsequent material cutting operations; When the second motor 306 moves upward, it drives the protection box 308 to move until the protection box 308 is away from the workpiece, which is convenient for subsequent unloading operations; When the support plate 302 moves upward and drives the second screw 404 to move upward, the second screw 404 moves upward and drives the first bevel gear 405 to rotate. The rotation of the first bevel gear 405 drives the second bevel gear 406 and the third bevel gear 503 to rotate in turn.
