[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0024] Embodiment:

[0025] Referring to Figures 1-3 , the double-end surface grinder wheel core plate rapid adjustment mechanism comprises:

[0026] The main shaft 5 is installed on the box body 3;

[0027] The pulley 2 is fixedly connected to the main shaft 5;

[0028] The grinding wheel 1 is fixedly connected to the main shaft 5;

[0029] The core plate 101 is fixedly connected to the grinding wheel 1;

[0030] Adjusting shaft 6 is fixedly connected to core plate 101;

[0031] The adjusting shaft 6 has an external thread on its surface;

[0032] Adjusting nut 7 is connected to adjusting shaft 6, and the internal thread of adjusting nut 7 matches the external thread on adjusting shaft 6.

[0033] The adjusting shaft 6 is a hollow shaft. A water cavity is opened in the core plate 101, and a water outlet hole 1011 is opened on the core plate 101. Multiple sets of water outlet holes 1011 are evenly distributed on the core plate 101. The adjusting shaft 6 is connected to the water cavity on the core plate 101.

[0034] Reference Figure 3 A connecting part 4 is fixedly connected to the core plate 101, and the connecting part 4 is guided and connected to the main shaft 5 by a flat key.

[0035] The spindle 5 is connected to the core plate 101 through the connecting part 4. During the operation, the core plate 101 and the spindle 5 can rotate synchronously, which can solve the problem of asynchronous rotation of the core plate 101 and the spindle 5 in the prior art. This solves the problem of displacement caused by asynchronous rotation of the core plate 101 and the spindle 5, which can easily cause the end face of the core plate 101 to be uneven with the end face of the grinding wheel 1, and easily cause workpiece blockage.

[0036] An anti-slip sleeve 8 is fixed on the main shaft 5, and the adjusting nut 7 is rotatably connected to the anti-slip sleeve 8.

[0037] Reference Figure 2 , Figure 3 By using the anti-disengagement sleeve 8 on the main shaft 5, the adjusting nut 7 can be effectively limited, thereby preventing the adjusting nut 7 from loosening and shifting.

[0038] Reference Figures 1-3 During normal use, the pulley 2 rotates, driving the spindle 5 to rotate. The workpiece passes horizontally through the double-end face grinder, and the workpiece is ground by the core plate 101 on the grinding wheel 1.

[0039] Reference Figures 1-3 When the position of the core plate 101 needs to be adjusted, the operator manually rotates the adjusting nut 7. The adjusting nut 7 will drive the adjusting shaft 6, which is threaded to it, to move. The movement of the adjusting shaft 6 will synchronously drive the core plate 101, which is fixedly connected to it, to move. When the end face of the core plate 101 is flush with the end face of the grinding wheel 1, the adjustment of the core plate 101 can be completed by stopping the rotation of the adjusting nut 7.

[0040] The adjusting nut 7 in the device drives the adjusting shaft 6 to rotate, and then drives the core plate 101 to move, thereby completing the position adjustment of the core plate 101, and the workers no longer need to adjust a plurality of adjusting screws behind the flange of the grinding wheel 1, thereby effectively improving the adjusting efficiency and the grinding production efficiency of the workpiece.

[0041] The above merely provides a preferred embodiment of the present application, and the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
