For example, the existing mechanical positioning mechanism has poor lateral position fine-tuning function, which results in the staff taking a long time to make lateral fine-tuning on the workpiece position after the workpiece to be processed is fixed (some existing processing equipment such as stamping machines, vertical drilling machines, etc. can only move vertically when processing the workpiece. At this time, it is necessary to make fine-tuning on the lateral position of the workpiece to align the processing point directly below the processing part). This brings certain interference to the staff's workpiece replacement efficiency, and thus there are certain usage defects.

The bottom of the connecting plate 21 is fixedly connected to the top of the rectangular slide bar 25, and the connecting plate 21 forms a sliding structure with the workbench 1 through the rectangular slide bar 25. By setting the connecting plate 21 and the workbench 1 as a sliding structure, the connecting plate 21 is smoother and more stable when moving laterally along the top of the workbench 1. The connecting seat 6 is fixedly installed on the right side of the movable bearing assembly 2, and the internal rotation of the connecting seat 6 is connected to the threaded adjustment rod 7, and the outer surface of the threaded adjustment rod 7 is threadedly connected to the bearing seat 8, and the bottom of the bearing seat 8 is fixedly connected to the top of the workbench 1.

[0023] like Figure 1-Figure 3As shown, the top of the workbench 1 is connected to a movable bearing assembly 2 in a left-right sliding manner, and a driving motor 3 is installed on the left side of the movable bearing assembly 2, and a bidirectional driving screw 4 is installed on the output shaft of the driving motor 3 through a coupling, and the top of the movable bearing assembly 2 is symmetrically slidably connected to a clamping and positioning assembly 5, the clamping and positioning assembly 5 includes a clamping plate 51, a cross-shaped slider 52, a connecting mechanism 53 and a T-shaped slider 54, and a cross-shaped slider 52 is fixedly installed on the bottom of the clamping plate 51, and the bottom of the cross-shaped slider 52 is fixedly connected to the connecting mechanism 53, and the interior of the connecting mechanism 53 is movably connected to the side of the bidirectional driving screw 4, and at the same time, a T-shaped slider 54 is symmetrically installed on the bottom of the clamping plate 51 front and back, the bottom of the clamping plate 51 is fixedly connected to the top of the T-shaped slider 54, and the clamping plate 51 forms a sliding structure with the bearing plate 23 through the T-shaped slider 54, The plate 23 makes the clamping plate 51 move more smoothly and stably along the top of the supporting plate 23.

At this time, The elastic buffer mechanism 55 and the rubber anti-slip pad 57 cooperate with each other so that the positioning plate 56 and the arc-shaped clamping block 58 will not cause wear to the outer surface of the workpiece when clamping and fixing the workpiece.
