[0033] Working principle of the present invention: when in use, the workpiece to be processed is placed on the processing plate 3, and the rear side of the workpiece is abutted against the front side of the first positioning plate 4, and then the lifting plate 15 is driven downward by the hydraulic rod 21. When the lifting plate 15 starts to move downward, it will drive the two rack plates 16 and the processing assembly 2 to move downward through two sets of elastic sliding mechanisms. The two rack plates 16 move downward and respectively drive the two spur gears 13 to rotate. The two spur gears 13 drive the two second bevel gears 14 to rotate through two rotating shafts. The two second bevel gears 14 respectively drive the two first bevel gears 12 to rotate. The two first bevel gears 12 respectively drive the two worms 10 to rotate. The two worms 10 respectively drive the two worm wheels 11 to rotate. The two worm wheels 11 respectively drive the two threaded rods 7 to rotate, and the two threaded rods 7 rotate in opposite directions, so that the two threaded sleeves 6 move relatively, and the two second positioning plates 5 move relatively, until the two second positioning plates 5 position and clamp the workpiece. When clamping is completed, the lifting plate 15 continues to move downward. At this time, the two second positioning plates 5 cannot move, so that the two long plates 17 will slide downward from the two long grooves respectively, and the two tension springs 18 will be stretched until the processing component 2 completes the processing of the workpiece. After the processing is completed, the lifting plate 15 moves upward under the drive of the hydraulic rod 21. First, the two long plates 17 will move upward in the two long grooves respectively until the tension springs 18 return to their original state. The lifting plate 15 continues to move upward, driving the two rack plates 16 to move upward, and the transmission in sequence can make the two second positioning plates 5 move in the opposite direction, and then the workpiece can be taken out. Through the upper device, the same type of workpiece can be quickly positioned and clamped, without manual marking and positioning, which is convenient for improving processing efficiency. When positioning other types of workpieces, it is only necessary to adjust the lateral position of the processing component 2 and the longitudinal position of the first positioning plate 4 during the first processing, and it has a wide range of uses.
