The above-mentioned scheme adjusts the angle of the grinding wheel, thereby polishing and polishing the bevel of the workpiece.

[0005] The above two schemes respectively adjust the supporting table and the grinding wheel in a rotating manner, thereby facilitating the polishing of the bevel of the workpiece, but both need to set a turnover (or rotary) mechanism with self-locking capability, and also use a five-axis machine tool, which has high requirements for numerical control and is relatively high in cost. SUMMARY

[0006] The purpose of the present application is to provide a top hammer bevel polishing auxiliary device with relatively low cost.

[0007] In order to achieve the above object, the present application adopts the following technical scheme: a top hammer bevel polishing auxiliary device, comprising a carrying mechanism and a positioning seat for supporting a workpiece, the carrying mechanism comprising a lifting assembly for moving the positioning seat up and down and a translation assembly for translating the positioning seat, the positioning seat being provided with an upwardly open positioning groove, the positioning seat being matched with a fixing seat for keeping the positioning seat in an inclined state, the fixing seat being provided with a V-shaped support groove for supporting the outer edge of the lower end of the positioning seat and a support surface for supporting the lower end surface of the positioning seat and being arranged in an inclined manner, the lifting assembly being connected with the positioning seat through a lifting tool.

[0008] The present application is provided with a fixing seat, when the positioning seat is placed in an inclined manner on the fixing seat, one edge side wall and the bottom die of the positioning seat are respectively supported on the two groove surfaces of the V-shaped support groove, at the same time, the ground of the positioning seat is also supported on the support surface, the present application supports and positions the positioning seat through the fixing seat, so that the positioning seat is kept in an inclined state, so that the surface to be polished of the workpiece (one large inclined surface or small inclined surface) is kept in a horizontal state, at this time, the grinding wheel assembly on the grinding machine can be directly moved downward or laterally to contact the surface to be polished of the workpiece, so as to polish.

[0009] The present application scheme can keep the positioning seat on which the workpiece is placed in an inclined state, so that the workpiece is inclined to keep the surface to be polished of the workpiece in a horizontal state, without the need to overturn or rotate the parts for supporting the positioning seat or the grinding wheel assembly, so that a conventional grinding machine with low cost can be adopted, without the need to adopt a five-axis machine tool with high numerical control requirement.
