[0027] As Figure 3 Shown, the bottom, side of base 3 are spaced apart and provided with square holes 301, for reducing the weight of base 3, while saving cost, the sidewall between each square hole 301 forms a grid-shaped reinforcing rib 302, the grid-shaped reinforcing rib 302 can disperse stress, reduce local stress concentration, improve the stability and rigidity of base 3 as a whole.

[0028] As Figure 2 Shown, base 3 is drivenly connected with servo assembly 4 below, the two sides of servo assembly 4 are provided with guide rails 5, base 3 is provided with sliding blocks 6 that are in sliding fit with guide rails 5, specifically, servo assembly 4 is used to drive base 3 to move along guide rails 5.

[0029] Further, the servo assembly 4 comprises a servo motor 401, an output end of the servo motor 401 is drivingly connected with a lead screw 402 consistent with the height of the guide rail 5, the servo motor 401 is used to drive the lead screw 402 to rotate, the base 3 is provided with a lead screw nut 403 threadedly connected with the lead screw 402, the lead screw 402 drives the base 3 to move through the thread cooperation with the lead screw nut 403, the consistency of the height of the lead screw 402 and the guide rail 5 can ensure that the rotary motion of the lead screw 402 can be accurately converted into the linear motion of the base 3, thereby reducing the error and deviation in the motion process, in addition, it can also ensure the smooth motion of the sliding block 6 in the linear direction, avoiding unnecessary friction and vibration when driving the base 3 to move, thereby improving the stability and precision of the workbench during processing.
