Since the screw tap 224 may be damaged after a long period of use, it is periodically replaced, when the screw tap 224 needs to be replaced, the worker first unscrews the second nut 222 on the socket head cap screw 226, then, the hexagon socket head cap screws 226 are pulled out from the third guide holes 221 and the fourth guide holes 225, the used tap 224 is then removed and a new tap 224 and a fixed shaft 223 are reloaded, with the fourth guide hole 225 and the third guide hole 221 located at the same horizontal line, and the hexagon socket head cap screws 226 are inserted into the fourth guide hole 225 and the third guide hole 221, and finally the second nuts 222 are screwed into the hexagon socket head cap screws 226, so that the replacement of the screw taps 224 is realized, the repeated use of the equipment is facilitated, the equipment is convenient to move, is suitable for more occasions, does not need to be tapped manually by rotating the screw tap 224, saves labor and labor, and is comfortable to use. After the main switch 17 is pressed, the control module controls the buzzer to sound for one second to stop when any button of the up-moving switch 18, the down-moving switch 19 and the tapping switch 191 is pressed, and if any button of the up-moving switch 18, the down-moving switch 19 and the tapping switch 191 is not pressed, the button is not pressed completely, so that the button can be guaranteed to be pressed completely, and the practicability of the equipment is improved.

When the tapping switch 191 is pressed, the control module controls the output shaft of the driving motor 27 to rotate clockwise, and at the same time, the control module controls the air pump 307 on the upper side to operate and the electronic control valve 308 on the lower side to open, so that the piston 302 moves downward in the cylinder 30, the guide sleeve 24 moves downward under the driving action of the first moving rod 303, the moving block 304 and the second moving rod 305, thereby realizing that the tap 224 automatically moves downward for tapping while rotating clockwise, the air pressure sensor 309 on the upper side can detect the air pressure between the piston 302 and the upper portion in the cylinder 30, when the air pump 307 on the upper side pumps air into the cylinder 30, the air pressure between the piston 302 and the upper portion in the cylinder 30 increases, when the air pressure value detected by the air pressure sensor 309 on the upper side is greater than the maximum set value in the control module, the control module controls the electronic control valve 308 on the upper side to open, and the air pressure between the piston 302 and the upper portion in, when the air pressure value detected by the upper air pressure sensor 309 is smaller than the maximum set value in the control module, the upper electronic control valve 308 is controlled to close, so that the piston 302 can move downwards, the air pressure in the air cylinder 30 can be ensured to be within a reasonable range, and the safety of the device is improved. When the guide sleeve 24 moves downwards to touch the second travel switch 29, the control module controls the driving motor 27 to rotate anticlockwise, and at the same time, controls the air pump 307 on the upper side and the electronic control valve 308 on the lower side to be closed, and controls the air pump 307 on the lower side and the electronic control valve 308 on the upper side to be opened, so that the screw tap 224 rotates anticlockwise and moves upwards automatically, the air pressure sensor 309 on the lower side can detect the air pressure between the piston 302 and the inner lower part of the air cylinder 30, when the air pump 307 on the lower side pumps air into the air cylinder 30, the air pressure between the piston 302 and the inner lower part of the air cylinder 30 is increased, when the air pressure value detected by the air pressure sensor 309 on the lower side is greater than the maximum set value in the control module, the control module controls the electronic control valve 308 on the lower side to be opened, the air pressure between the piston 302 and the inner lower part, and then the electric control valve 308 on the lower side is controlled to be closed, so that the piston 302 can move upwards, the air pressure in the air cylinder 30 can be ensured to be in a reasonable range, and the safety of the device is improved. When the guide sleeve 24 moves upwards to touch the first travel switch 28, the control module controls the driving motor 27 to rotate clockwise, and simultaneously controls the air pump 307 on the upper side and the electric control valve 308 on the lower side to be opened, and controls the air pump 307 on the lower side and the electric control valve 308 on the upper side to be closed, so that repeated operation is realized, multiple tapping can be realized, and when tapping is completed and the screw tap 224 is located above a workpiece, the tapping switch 191 is pressed down, and the electric control valve 308, the air pump 307 and the driving motor 27 all stop working. Therefore, the tap 224 does not need to move up and down manually, the constant speed of the movement of the tap 224 is improved, and the labor is saved.

When the press block 7 moves downwards, the friction plate 314 also moves downwards along with the press block, the friction plate 314 starts to be extruded after contacting the surface of the workpiece, the hard spring 315 is compressed, the friction plate 314 moves upwards, the friction plate 314 extrudes the pressure sensor 316, when the pressure value on the pressure sensor 316 is equal to the pressure value set by the control module, the control module controls the speed reducing motor 13 to stop working, so that the workpiece is automatically clamped, the condition that whether the workpiece is clamped and then the speed reducing motor 13 is closed is not required to be judged manually, and the process is more intelligent.

After the worker presses the main switch 17, the control module controls the high-speed motors 325 at the right part and the rear part to respectively drive the sector gears 326 on the high-speed motors to rotate clockwise, the corresponding circular gears 324 rotate anticlockwise, the rotating shaft 321 and the laser emitting head 323 rotate anticlockwise, when the sector gears 326 are separated from the circular gears 324, the rotating shaft 321 and the laser emitting head 323 rotate clockwise under the action of the torsion spring 322, when the sector gears 326 are meshed with the circular gears 324 again, the rotating shaft 321 and the laser emitting head 323 rotate anticlockwise again, so that the laser emitting head 323 can continuously swing forwards and backwards, and simultaneously the control module controls the laser emitting heads 323 at the right part and the rear part to work, because the swinging speed of the laser emitting head 323 is higher under the driving action of the high-speed motors 325, the worker can see a straight line formed when the laser emitting heads 323 swing by naked eyes, and the straight line that the laser emission head 323 of the right part swings constantly and forms coincides with X axle with screw tap 224 middle point as the origin of coordinates, the straight line that the laser emission head 323 of the back part swings constantly and forms coincides with Y axle with screw tap 224 middle point as the origin of coordinates, two straight lines will have a cross point like this, this cross point and screw tap 224 middle point lie on the same vertical line, when putting the work piece like this, the staff only needs to locate the hole on the work piece on the cross point of two rays, it puts the accurate of the work piece to be convenient for the staff, has improved the convenience that the apparatus uses, when pressing the master switch 17 again, high-speed motor 325 and laser emission head 323 will close.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
