[0024] In the specific implementation process, such as Figures 1-4As shown in the figure, the desktop automatic tapping machine includes a frame 1 for supporting and fixing various components. A chute 2 is provided on the surface of the frame 1. Two sets of units are oppositely arranged in the chute 2, and the chute 2 restricts the movement path of the units. Through holes in the horizontal direction are provided at the bottoms of both sets of units. The same threaded rod 3 is threadedly connected in the two through holes. The threaded directions at both ends of the threaded rod 3 are opposite, and the threaded directions of the two sets of units at their positions are opposite.

The housing of the motor 4 is fixedly connected to the frame 1. The unit includes a base 5, a lifting frame, a clamping device, and a body 6. The bottom of the base 5 is arranged inside the chute 2. A through hole is provided in the horizontal direction on the base 5, and the threaded rod 3 with opposite threaded directions at both ends is threadedly connected in the through hole. The motor 4 drives the threaded rod 3 to rotate, driving the two sets of units to move in opposite directions. One end of the top surface of the base 5 near the center of the threaded rod 3 is fixedly connected to the lifting frame, and a clamping device is fixedly connected to the top surface of the lifting frame. The clamping device includes a U-shaped plate 7. Elastic members are fixedly connected to both sides of the top surface of the U-shaped plate 7. The other end of the top surface of the base 5 is fixedly connected to the body 6. The lifting frame is driven by an electric cylinder. The lifting frame includes a fixed frame 8 and a moving frame 9. The bottom surface of the fixed frame 8 is fixedly connected to the surface of the base 5. The inner side wall of the fixed frame 8 is adapted to the outer side wall of the moving frame 9. The top surface of the moving frame 9 is fixedly connected to the bottom surface of the U-shaped plate 7. The bottom surface of the electric cylinder is fixedly connected to the inner bottom wall of the fixed frame 8, and the top surface of the electric cylinder is fixedly connected to the inner top wall of the moving frame 9. The electric cylinder drives the moving frame 9 to have a relative displacement with the fixed frame 8, realizing the lifting of the lifting frame. The elastic member includes a limiting frame 10, a limiting block 11, and a spring 12. The outer side wall of the limiting frame 10 is fixedly connected to the top surface of the U-shaped plate 7.

If the width of the parts does not exceed the maximum clamping size of the machine, according to the length of the parts, by starting the motor 4, the motor 4 drives the threaded rod 3, and the threaded rod 3 and the sliding groove 2 act together to make the two bases 5 move horizontally in opposite directions. According to the height of the parts, the electric cylinder is started, and the electric cylinder drives the moving frame 9 to have a relative displacement with the fixed frame 8, realizing the lifting of the lifting frame. After adjustment, the parts can be placed between two opposite limiting blocks 11. After the limiting blocks 11 are squeezed, the other ends of the limiting blocks 11 squeeze the springs 12 until the bottom surface of the parts fits the top surface of the U-shaped plate 7. After the parts are placed, the machine body 6 can be started to process the parts. After the batch of parts processing is completed, the fan 14 can be started, and the air is discharged through the air duct 15 and the air outlet 16 to clean the machine.
