Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Please refer to Figure 1-2, the present invention provides a technical solution: an adjustable roller end surface grinding device, including a base 1, a fixed block 3 is installed on the top right side of the base 1, and an adjusting screw is inserted horizontally on the fixed block 2. 3, and the fixed rod 2 is provided with a threaded hole matching the adjusting screw 3. The right side of the adjusting screw 3 is equipped with a handle 4, the left side of the adjusting screw 3 is installed with a right clamp 5 through a bearing, and the top left side of the base 1 is supported by The rod 6 is installed with the left clamp 7, the right clamp 5 and the left clamp 7 are provided with a roller shaft 8, the top left and right sides of the base 1 are installed with uprights 9, the top of the two sets of uprights 9 are installed with the top plate 10, and the bottom center of the top plate 10 is installed Hydraulic device 11, the bottom output end of the hydraulic device 11 is equipped with a telescopic rod 12, the bottom of the telescopic rod 12 is equipped with a shock-absorbing plate 13, and the bottom of the shock-absorbing plate 13 is equipped with a motor 14. The motor 14 is connected to an external power supply through a switch, and the bottom of the motor 14 Install grinding block 15 at the output end.

Among them, the right clamp 5 and the left clamp 7 are clamps with the same structure. The bottom of the right clamp 5 is equipped with a slider, and the top of the base 1 is provided with a chute matching the slider. The handle 4 drives the adjustment screw 3 to rotate to make The right clamp 5 is close to the left clamp 7 to clamp the roller shaft 8. At this time, the slider moves in the chute, which can prevent the right clamp 5 from rotating with the adjusting screw 3;
