The invention discloses a forward and reverse mechanical chuck of a grinding machine, which comprises a tip, a center tip sleeve, an outer shell, a one-way bearing, a pick driving ring, a pressure ring and a plurality of picks. When processing starts, the grinding machine rotating power head starts Rotate the slot hole of the outer shell to drive the outer shell to rotate clockwise, so that the limit pins of the shell picks move the picks to make them close to each other until the workpiece is clamped; at the same time, each pick drives the pick to drive The ring is connected to the column pin, so that the driving paddle drives the ring and the pressure ring to rotate counterclockwise. The tension spring pin of the compression ring and the tension spring pin of the shell will tighten the tension spring. Under the action of tension, the outer shell and the paddles drive the ring to reverse, and each paddle expands outward to loosen the workpiece. The forward and reverse mechanical chuck of the grinding machine of the present invention automatically clamps the workpiece during the rotating process, automatically releases the workpiece after processing, realizes automatic clamping, reduces clamping time, reduces manpower, improves work efficiency, and is accurate in centering and clamping. firm.
Description
technical field [0001] The invention relates to a forward and reverse mechanical chuck of a grinding machine. Background technique [0002] When the grinding machine grinds the surface of the workpiece, it needs to use the corresponding chuck to fix the workpiece so as to drive the workpiece to rotate for processing. Existing grinding machines mostly use manual clamping of the workpiece, and use a wrench to twist the chuck to clamp and loosen the workpiece. The clamping time is long, the clamping is laborious, and the workpiece is easy to loosen and eccentric, which affects the processing quality of the workpiece. Contents of the invention [0003] The purpose of the invention is to solve the technical problems that the manual clamping of the workpiece by the current grinding machine takes a long time, the clamping is laborious, the workpiece is easy to loosen and eccentric, and the processing quality of the workpiece is affected. [0004] In order to achieve the purpose ...
