The sliding block is installed on the sliding block on the slide rail and achieves low-friction sliding through balls or sliding blocks. The sliding block is connected with a drive screw, and the rotation of the drive screw can drive the sliding block to move along the slide rail. The drive screw adopts a lead screw or a ball screw and is driven by a manual knob. In order to fix the position of left and right fine adjustment sliding table 121, a locking device is provided on the sliding block. The locking device can fix the position of the sliding block by tightening locking bolts to prevent displacement during grinding.

[0035] In an embodiment, the structure of the up-down fine adjustment sliding table 122 is similar to that of the left-right fine adjustment sliding table 121, but its moving direction is the vertical direction. The up-down fine adjustment sliding table 122 includes a base, a sliding rail, a sliding block, a driving screw, and a locking device. Specifically, the base of the up-down fine adjustment sliding table 122 is fixed on the sliding block of the left-right fine adjustment sliding table 121 to realize vertical adjustment.

The sliding block is connected with a vertical driving screw, and the rotation of the driving screw can drive the sliding block to move up and down along the sliding rail. The driving screw is a lead screw or a ball screw, which is driven by a manual knob. In order to fix the position of the up-down fine adjustment sliding table 122, a locking device is arranged on the sliding block, which can fix the position of the sliding block by tightening the locking bolt to ensure that there is no vertical displacement during grinding.

[0036] The left-right fine adjustment sliding table 121 and the up-down fine adjustment sliding table 122 realize accurate adjustment of the workpiece 100 through the above structure. The specific working principle is as follows: by rotating the driving screw of the left-right fine adjustment sliding table 121, the sliding block can move along the horizontal sliding rail, thereby adjusting the position of the workpiece 100 in the horizontal direction. After adjusting to the required position, the sliding block is fixed by the locking device to ensure that there is no horizontal displacement during processing. By rotating the driving screw of the up-down fine adjustment sliding table 122, the sliding block can move along the vertical sliding rail, thereby adjusting the position of the workpiece 100 in the vertical direction. After adjusting to the required position, the sliding block is fixed by the locking device to ensure that there is no vertical displacement during processing.

[0037] The left-right fine adjustment sliding table 121 and the up-down fine adjustment sliding table 122 can realize accurate adjustment of the workpiece 100 in the horizontal and vertical directions. Based on the design of high-precision sliding rails and low-friction sliding blocks, the moving accuracy of the fine adjustment sliding table is guaranteed, avoiding the instability of the workpiece 100 during grinding, thereby improving the processing accuracy and the roundness of the workpiece 100. In addition, through the use of the locking device, the workpiece 100 can maintain stable positioning during processing, further enhancing the processing effect.
