Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grinding machine, more specifically, the utility model relates to a clamping tool of vertical grinding machine. BACKGROUND

[0002] The vertical grinding machine is used to sharpen various cutters and tools. In addition to some common requirements of grinding machines, the vertical grinding machine also has high speed, simple structure, wide application, and general manual operation. The vertical grinding machine is frequently used in the production of cutters, and is generally operated by fixed personnel. Some maintenance is poor, and the injury accidents caused by not following the safety operation procedures during grinding operation also account for a considerable proportion.

[0003] When using the ordinary vertical grinding machine, the worker usually holds the part, and the part to be processed is in contact with the grinding wheel of the vertical grinding machine, so that the part can be ground. Since the part will be subjected to a large force during grinding, the force will be transmitted to the worker through the part. At this time, the worker can only hold the part, and cannot guarantee the stability of the part. Therefore, the stability of the part during processing is poor, and the processing precision and quality of the part are low.

[0004] According to the search, the patent with the publication number CN213106152U discloses a vertical grinding machine for improving processing quality. When the vertical grinding machine works, the part can be fixed on the clamping mechanism. The clamping mechanism, operating mechanism and workbench play a supporting role. The worker only controls the movement of the part, so as to effectively improve the stability of the part during processing, thereby improving the processing quality of the part.

[0005] When the above-mentioned vertical grinding machine for improving processing quality is actually used, the clamping device of part of the vertical grinding machine is not convenient for clamping the irregular-shaped workpiece.
