By rotating the bidirectional lead screw 15, the two adjusting blocks 16 are brought closer to each other until the grinding block 17 is in close contact with the surface of the bar stock. At this time, the rotating seat 4 is controlled to rotate, and the electric guide rail 13 drives the movable seat 14 to move left and right to achieve surface grinding of the bar stock blank.

[0024] Please see Figures 1-5 In this embodiment, a waste discharge groove is provided at the upper end of the base 1.

The electric push rod 10 drives the moving block 12 to approach the other end of the bar until the top block 11 is in contact with the bar, so as to achieve stable support for the bar.

[0025] Please see Figures 1-3In this embodiment, the output end of the electric guide rail 13 is fixedly connected to the movable seat 14, the upper and lower ends of the bidirectional lead screw 15 are rotatably connected to the movable seat 14, the upper end of the bidirectional lead screw 15 extends to the outside of the movable seat 14 and is fixedly installed with an adjustment knob 151, the adjustment blocks 16 are arranged symmetrically up and down, the rear end of the adjustment block 16 is slidably connected to the movable seat 14, the bidirectional lead screw 15 and the adjustment block 16 are threadedly connected, and the grinding block 17 and the front end of the adjustment block 16 are detachably connected. By rotating the adjustment knob 151, the bidirectional lead screw 15 is driven to rotate, so that the two adjustment blocks 16 slide along the surface of the movable seat 14 and approach each other until the grinding block 17 is tightly attached to the surface of the bar stock.

The electric push rod 10 drives the moving block 12 to approach the other end of the bar stock until the top block 11 is in contact with the bar stock, achieving stable support for the bar stock. Rotating the adjustment knob 151 drives the bidirectional lead screw 15 to rotate, causing the two adjustment blocks 16 to slide along the surface of the moving seat 14 and approach each other until the grinding block 17 is in close contact with the surface of the bar stock. At this time, the drive motor is turned on to drive the rotating seat 4 to rotate, and at the same time, the electric guide rail 13 drives the moving seat 14 to move left and right, realizing the surface grinding of the bar stock blank.
