The outer wall of the transverse moving base 803 is fixedly connected to a first motor 806. The output end of the first motor 806 is fixedly connected to one of the transverse lead screws 802, which can finely adjust the position of the clamping block 3; the second slider 901 is fixedly connected to the transverse moving base 803.

[0024] Workflow: Place the automotive parts on the chuck 1, and rotate the 4 handwheels 6 respectively to rotate the first lead screw 5, thereby driving the clamping block 3 to slide in the first chute 2. The 4 clamping blocks 3 can ensure that automotive parts of various specifications can be clamped on the chuck 1. Due to the existence of the first limit block 4 and the second limit block 7, they play a supporting role for the first lead screw 5 and also prevent the clamping block 3 from falling off the chuck 1. The position sensor 10 detects whether the position of the automotive part is the correct position to be processed. If it is not in the correct position to be processed, a signal will be sent to the chip 11. The chip 11 controls the rotation of the first motor 806, and the first motor 806 drives the rotation of the transverse lead screw 802, causing the first slider 801 to move along the transverse lead screw 802. On the transverse lead screw 802, the first slider 801 can make fine movements. Under the action of the first synchronous pulley 804 and the first synchronous belt 805, the two transverse lead screws 802 rotate synchronously, thereby adjusting the transverse position of the chuck 1. The transverse moving base 803 supports the transverse lead screw 802, the first synchronous pulley 804 and the first motor 806. At the same time, the chip 11 controls the rotation of the second motor 906, and the second motor 906 drives the rotation of the longitudinal lead screw 902, causing the second slider 901 to move along the longitudinal lead screw 902. On the longitudinal lead screw 902, the second slider 901 can make fine movements. Under the action of the second synchronous pulley 904 and the second synchronous belt 905, the two longitudinal lead screws 902 rotate synchronously, thereby adjusting the longitudinal position of the transverse moving mechanism 8 and further adjusting the longitudinal position of the chuck 1. The longitudinal moving base 903 supports the longitudinal lead screw 902, the second synchronous pulley 904 and the second motor 906. Under the combined action of the transverse moving mechanism 8 and the longitudinal moving mechanism 9, the automotive parts can be adjusted to the correct position. By using the position sensor 10 and the chip 11, the automatic control of the entire device can be realized, reducing the working intensity of workers and making the adjustment more accurate.
