Abstract

An anti-deformation grinding member with electroplated single-layer diamond, a grinding ring and a special-shaped grinding wheel. The anti-deformation grinding member comprises a grinding layer (1) and a grinding member base (2), wherein the grinding layer (1) is fixedly bonded to the grinding member base (2); and the grinding layer (1) is a plated layer of single-layer diamond abrasive particles. The length of a cross section of the grinding layer (1) from one side corresponding to the minimum axial machining allowance of a workpiece to the other side is equal to the thickness of the grinding layer (1); and the length of a cross section of the grinding layer (1) from one side corresponding to another axial point of the workpiece to the other side is equal to the machining allowance of an axial point / the minimum machining allowance×the thickness of the grinding layer. The longer the length of the circumferential corresponding grinding layer, the more the diamond abrasive particles contained in the grinding layer, and thus the higher the wear resistance; and the grinding layer corresponds to a part with a large machining allowance. The shorter the length of the circumferential corresponding grinding layer, the fewer the diamond abrasive particles contained in the grinding layer, and thus the lower the wear resistance; and the grinding layer corresponds to a part with a small machining allowance. By means of adjusting the circumferential length of the grinding layer corresponding to each axial point of a workpiece, the uniform wear of the grinding member is realized, and the shape of the outer peripheral surface of a special-shaped grinding wheel remains unchanged during machining.

[0148] Embodiment 10

[0149] In the embodiment, the center of the grinding wheel base 7 is provided with an installation hole 10 penetrating upward and downward for installing a center shaft.

[0150] The structure of the scheme is simple, and the installation hole 10 is reasonably arranged to facilitate subsequent assembly.

[0151] During assembly, the driving element is fixedly connected with one end of the vertically arranged center shaft, and the other end of the center shaft extends into the installation hole 10 and is fixedly connected.

[0152] The grinding principle of the present application is as follows:

[0153] The consumption rates of each point on the outer circumferential surface of the grinding wheel are the same to achieve equal shape consumption and realize the anti-deformation function.

[0155] The anti-deformation mechanism adopted by the present application is a general mechanism: according to the different machining allowances of each point on the outer circumferential surface of the grinding wheel, the number of diamond abrasive grains is different; the number of diamond abrasive grains on the corresponding position on the grinding element is large at a position with a large machining allowance, and the wear resistance is high; the number of diamond abrasive grains on the corresponding position on the grinding element is small at a position with a small machining allowance, and the wear resistance is low; thus, the consumption rates of each point on the outer circumferential surface of the grinding wheel tend to be the same to achieve equal shape consumption and realize the anti-deformation function.

[0156] The creativity of the present application lies in: according to the different machining allowances of each point on the grinding wheel, the circumferential surface of the grinding element is bent to adjust the circumferential length of the grinding layer on the grinding element at the corresponding points on the grinding end (the circumferential length of the grinding layer is in a proportional relationship with the number of diamond abrasive grains), so as to realize the anti-deformation function. The process is simple and easy to implement; the optimized scheme: the grinding element can be batch-produced in a planar manner, the plating layer is first completed, and then the bending, stretching, extruding and stamping processes are used to form the required, easily quantifiable, bent grinding element for different workpiece special-shaped requirements.

[0157] The beneficial effects of the present application are as follows:

[0158] (1) The grinding member is easy to manufacture in scale, in a single layer of diamond abrasive grain manner, so that the electroplating process is easy to control and low in cost;

[0159] (2) The grinding wheel can be assembled and suitable for automatic operation;

[0161] (4) It is suitable for expansion or combination with various binders;

[0162] (5) It is convenient, easy, quantifiable and better in effect for implementing anti-deformation on a complex grinding surface, compared with the prior art.
