[0026] The tapping device includes a tapping motor 23 and a tapping head 24 fixedly connected to the output shaft of the tapping motor 23 . The tapping motor 23 is fixedly connected to the front end of the lifting plate 22 .
[0027] It also includes two symmetrically arranged clamping switching structures 4, which are both installed on the synchronous clamping structure 3. Through the arrangement of the clamping switching structures 4, it is convenient to clamp and fix the square workpiece.
[0028] Further as Figures 1-4As shown, it is worth explaining in detail that in order to be able to clamp and fix the cylindrical workpiece in linkage during the process of the lifting plate 22 driving the tapping device to move downward, a synchronous clamping structure 3 is set, including a transverse moving channel opened in the middle of the top of the processing table 1. The vertical section of the transverse moving channel is an I-shaped structure. Two symmetrically arranged clamping seats 37 are slidably connected in the transverse moving channel. The opposite ends of the two clamping seats 37 are each provided with an arc-shaped clamping opening that is convenient for clamping and fixing the cylindrical workpiece. The tops of the two clamping seats 37 are rotatably connected to push-pull rods 36 The other ends of the push-pull rods 36 are rotatably connected to the top of the trigger seat 31, and the trigger seats 31 are slidably connected to the longitudinal movable grooves provided at the top of the processing table 1. The vertical sections of the trigger seat 31 and the longitudinal movable grooves are convex structures. The rear ends of the trigger seats 31 are movably extended to the outside of the processing table 1 and are provided with inclined surfaces a32, and the front ends of the trigger seats 31 are connected to the inner wall of the movable grooves through springs 35. The inclined surfaces a32 are movably overlapped on the inclined surfaces b34 provided at the bottom ends of the inverted L-shaped trigger rods 33, and the top ends of the inverted L-shaped trigger rods 33 are fixed to the outside of the lifting plate 22.
[0029] The spring 35 in the figure is in a normal state, neither stretched nor compressed.
[0030] Further Figures 1-4 As shown, it is worth explaining in detail that, in order to be able to further clamp and fix the square structure workpiece on the basis of the above-mentioned synchronous clamping structure 3, a clamping switching structure 4 is set, including a slider 42 slidably connected in the slide groove provided at the top of the clamping seat 37, and the vertical section of the slider 42 is an I-shaped structure. The top of the slider 42 is fixedly connected to a clamping block 41, and the clamping surface of the clamping block 41 is provided with a V-shaped clamping opening. Threaded channels are opened through the clamping block 41 and the slider 42, and the same hand screw 43 is threadedly connected in the two threaded channels. After the hand screw 43 is locked, its bottom end will be pressed against the bottom wall of the slide groove.

By starting the electric push rod 21, the lifting plate 22 is pushed downward, driving the tapping device to move downward, and at the same time driving the two inverted L-shaped trigger rods 33 to move downward, so that the inclined surfaces b34 squeeze the inclined surfaces a32, causing the two trigger seats 31 to squeeze the springs 35. With the cooperation of the push-pull rod 36, the two clamping seats 37 move relatively toward each other, and the cylindrical workpiece placed between the two clamping seats 37 can be clamped and fixed. Moreover, the tapping device can continue to move downward to realize the tapping and opening of the workpiece, greatly improving the processing efficiency. Secondly, when it is necessary to clamp a square workpiece, the two hand-tightening screws 43 can be loosened, and the two clamping blocks 41 can be manually moved relatively toward each other, so that the two clamping blocks 41 respectively cover the top of the arc-shaped clamping openings. Then, when the lifting plate 22 moves downward later, with the linkage effect of the synchronous clamping structure 3, it is convenient to clamp and fix the square workpiece, greatly expanding the applicable range of the clamping device.
