[0036] Embodiment: When in use, first install the workpiece on the positioning frame 9, and then simultaneously rotate the drive motors 6 inside the two bases 2 forward or backward. Then, under the action of the drive gears 5 and the drive racks 4, the connecting disk 3 is driven to rotate.

The longitudinal drive motor 13 of the longitudinal drive mechanism drives the cross beam 14 to adjust its longitudinal position along the longitudinal guide rail 10 at the top of the base 2 through the longitudinal slider 11 at its bottom under the action of the transmission lead screw 12. At the same time, move the lower working head 22 laterally along the second lateral guide rail 20 on the surface of the ground rail 1. When the central axes of the upper pressure foot sleeve 25 at the bottom of the upper working head 19 and the lower pressure foot sleeve 27 at the top of the lower working head 22 are in the same straight line position, simultaneously drive the upper working head 19 and the lower working head 22 to move towards the workpiece through the action of the upper slide block 18 and the lower slide block 26. When the upper pressure foot sleeve 25 below the upper working head 19 touches the workpiece, after the pressure sensor 24 fixedly connected to the pressure foot plate 23 senses that the pressure reaches a certain range, the upper slide block 18 and the upper working head 19 stop moving, and the lower slide block 26 drives the lower working head 22 to move upward until it presses against the other side of the workpiece. At this time, the upper working head 19 and the lower working head 22 clamp the workpiece. The working units such as drilling, gluing, riveting, distance measuring, milling, and pin inserting provided inside the upper working head 19 start to work.
