The invention discloses a multifunctional small punch
grinding device and relates to the technical field of small-punch
grinding. The multifunctional small punch
grinding device comprises a main shaft, a workpiece fixing part, a transmission shaft, a gear set and a
handle, wherein the main shaft, the workpiece fixing part, the transmission shaft, the gear set and the
handle are arranged in the left-right direction, the workpiece fixing part is used for fixing a workpiece at the left end of the main shaft, the transmission shaft is arranged in the left-right direction and connected with the main shaft, when the
handle is shaken, the gear set, the transmission shaft and the main shaft are sequentially driven to rotate, and the workpiece is driven to rotate. The multifunctional small punch grinding device further comprises a floating sliding block, a lever, an
explorator and an
idler wheel, wherein the floating sliding block can move up and down, the
idler wheel enables the floating sliding block to be delivered to a floating sliding block adjusting screw along an
explorator track through the lever, the floating sliding block and the
explorator track synchronously float up and down, up-down floatation is converted into up-down elasticity which is used for adjusting the spring and operating the distance of a
grinding wheel of a grinder, and therefore grinding
machining of special-shaped parts such as an oval-shaped part can be achieved. The multifunctional small punch grinding device has the advantages of being multifunctional and convenient to use and can be appropriate for ordinary die making factories and
machining and repair of die small punches in a circle, square, other equilateral polygons, flat, oval shape and the like in the process of repair when a die is used.
