Detailed ways

Figure 1 is a schematic structural view of a grinding device for circular guide rails of vertical lathes. The grinding device mainly includes three parts: a positioning mechanism, a turning mechanism and a grinding mechanism.

The positioning mechanism is a centering axle sleeve and a fixed disc 10 that can match the base of the vertical car, and the fixed disc 10 can be fixedly connected to the base of the vertical car by bolts.

The rotary mechanism includes a feed gearbox 6, a rotary disk 9 and a feed motor 11. The feed gearbox 6 is connected to the rotary disk 9 by bolts. The rotary disk 9 can rotate along the guide rail on the fixed disk 10. It is installed on the top of the feed gearbox 6, and drives the rotary table to rotate through the transmission device. The feed motor 11 is installed on the top of the feed gearbox 6, and controls the rotary motion of the rotary disk 9 through a worm gear transmission; the whole rotary mechanism rotates on the fixed disk 10 through the feed motor 11. One end of the feed gearbox 6 on the slewing mechanism is equipped with the grinding head 1, and the opposite end is equipped with a support and a balance counterweight mechanism for balancing the weight of the grinding head and the connecting body.

The grinding device consisting of the grinding head 1, the feed screw 4, the rotary slide 3 and the connecting body 5 is connected to the feed gearbox 6 through the connecting body 5; 5 and the feed gearbox 6 are connected by bolts.
