The first ball screw driving mechanism 11 is configured to drive the drilling mechanism 50 to move horizontally along the lateral direction of the base 10. For example, the slide plate of the first ball screw driving mechanism 11 and the drilling mechanism 50 are connected through an L-shaped support column 13. One end of the L-shaped support column 13 is vertically connected to the slide plate of the first ball screw driving mechanism 11, and the other end is connected to the drilling mechanism 50. The first ball screw driving mechanism 11 drives the L-shaped support column 13 to move horizontally along the lateral direction of the base 10 through the slide plate, thereby driving the drilling mechanism 50 arranged at the other end of the L-shaped support column 13 to move horizontally along the lateral direction of the base 10 to adjust the punching position. The structure is simple and easy to manufacture.

[0029] At least two telescopic rods 121 are laterally arranged on the slide of the second ball screw drive mechanism 12, wherein the movable end of one telescopic rod 121 is hinged to the lower surface of the processing table 20, and the other telescopic rod 121 is hinged to a slider 23 arranged on the lower surface of the processing table 20, and the slider 23 can slide along the length direction of the lower surface of the processing table 20. The second ball screw drive mechanism 12 is configured to drive the processing table 20 to move horizontally along the longitudinal direction of the base 10, thereby driving the automotive parts to move longitudinally. By adjusting the height of each telescopic rod 121 respectively, the processing table 20 hinged thereto can be tilted left and right, thereby tilting the automotive parts. However, the setting position of the telescopic rod 121 on the slide of the second ball screw drive mechanism 12 is not limited to this. For example, according to the processing requirements of the automotive parts, the telescopic rod 121 is arranged on the slide of the second ball screw mechanism 12 to be longitudinally relatively arranged, and can also be arranged relatively along the diagonal of the slide of the second ball screw drive mechanism 12.

[0033] In another embodiment, the processing table 20 also includes a displacement sensor, which is configured to measure the longitudinal horizontal displacement of the processing table 20 along the base 10. An LVDT (differential transformer) displacement sensor can be selected. It has the advantages of simple structure, small size, long service life, frictionless measurement structure, strong output signal, high sensitivity and high precision.

The L-shaped limit plug includes an insertion portion 39 and a downward pressing portion 40. A side wall of the slot Each of the plurality of positioning holes is provided with a positioning hole, each of which is threadedly connected with an adjusting bolt 41, and the adjusting bolt 41 is configured to adjust the height of the L-shaped limit plate inserted into the slot. When the automobile accessory needs to be clamped horizontally, the automobile accessory is placed on the two moving blocks 37. According to the length of the automobile accessory, the moving blocks are moved to the two ends of the automobile accessory to abut against the insertion part 39, and the moving blocks 37 are fixed to the slide rail 36 by the fixing bolt 38. When it is necessary to limit the vertical displacement of the automobile accessory, according to the thickness of the automobile accessory, the height of the L-shaped limit plate inserted into the slot is adjusted, and the L-shaped limit slot is locked by the adjusting bolt, so that the upper surface of the automobile is tightly abutted against the lower pressing part 40.
