Existing grinding devices are mainly composed of a workbench, a grinding head and a driving part that controls the operation of the grinding head. The existing workbench mainly moves in a single direction, so that the grinding head can only grind different positions of the horizontal surface of the workpiece clamped on the workbench. The single orientation and position of this grinding cannot achieve multi-angle grinding effects on the remaining surfaces of the workpiece. For workpieces that need to be polished on multiple sides, it is necessary to disassemble and replace the grinding surface after grinding one side, which is more troublesome. Summary of the invention

[0003] The technical problem to be solved by the utility model is that the existing workbench mainly moves in a single direction, so that the grinding head can only grind different positions of the horizontal surface of the workpiece clamped on the workbench. The single grinding direction and position cannot achieve the multi-angle grinding effect on the remaining surfaces of the workpiece. For workpieces with multiple surfaces that need to be polished, it is necessary to disassemble and replace the grinding surface after polishing one surface, which is quite troublesome.

[0005] The beneficial effects of the utility model are as follows: by cooperating with the adjusting component and the rotating processing table, it is convenient to adjust the angle between the workpiece clamped on the processing table and the grinding component, and it is convenient for the grinding component to grind the workpiece surface at different angles thereto, thereby improving the grinding efficiency.

[0006] As a further improvement of the present invention, the technical problem to be solved is: how to use the adjustment component to change the position of the processing table.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the adjustment component includes a rotating plate that rotates on one of the mounting plates and is coaxial with the processing table, a positioning rod is provided on the rotating plate that rotates through a torsion spring shaft, a positioning plate is fixed on the mounting plate, a plurality of positioning notches for engaging with the positioning rod are evenly opened on the positioning plate, and a limit piece for limiting the rotation of the positioning rod is provided on the peripheral side of the positioning plate.

[0008] The beneficial effect of the above improvement is that the angle of the workpiece clamped on the processing table is changed by engaging the rotating plate coaxial with the processing table with the positioning notches at different positions.

[0009] As a further improvement of the utility model, the technical problem to be solved is: how to limit the positioning rod to avoid accidental contact with the positioning rod so that it is disengaged from the positioning notch.

[0010] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the limiting member includes a connecting ring plate slidably arranged on the outside of the positioning plate and multiple limiting plates arranged at the front end of the connecting ring plate, the limiting plates correspond one to one with the positioning notches, a sliding groove is provided on the outside of the positioning plate, and a sliding block sliding with the sliding groove is provided on the inner side of the connecting ring plate.

[0011] The beneficial effect of the above improvement is: when the positioning rod is engaged with the corresponding positioning notch, the sliding connecting ring plate causes the limit plate to move to the outside of the positioning rod, thereby achieving the effect of limiting the positioning rod, wherein the extreme positions of the slider respectively represent the two states of the limit plate being open and closed with respect to the positioning notch, and the friction between the slider and the slide groove is relatively large, and a certain force is required to rotate the connecting ring plate.

[0012] The utility model further improves the technical solution adopted as follows: an L-shaped pull rod is arranged outwardly at the eccentric end of the positioning rod.

[0013] The beneficial effect of the above improvement is that it is convenient for the operator to pull the pull rod to rotate the machine tool grinding assembly to disengage from the engagement with the positioning notch. BRIEF DESCRIPTION OF THE DRAWINGS
