The hard
alloy numerical control grinding equipment comprises a base plate, a first air cylinder and a
machining clamping frame are installed on the upper surface of the base plate, a fixing clamping frame is fixedly installed at the end of a
piston rod of the first air cylinder, and a plurality of fixing screws are installed on the fixing clamping frame in a threaded mode. A second air cylinder is fixedly mounted on the side face of the
machining clamping frame, a sliding plate is fixedly mounted at the end of a
piston rod of the second air cylinder, a sliding seat is slidably arranged on the side face of the sliding plate, limiting channels are formed in the upper side face and the lower side face of the
machining clamping frame, and limiting blocks are slidably mounted in the limiting channels. A motor I is fixedly mounted on the surface of one of the limiting blocks; the inserting column is inserted into the column groove to be matched with the inserting rod to be inserted into the rod groove for use, stable locking of the
tool bit is achieved, compared with threaded connection, the phenomenon that the
tool bit is clamped and difficult to disassemble due to thread damage can be prevented, the structure is simple, and disassembly, replacement, operation and use of the
tool bit are facilitated.
