Multifunctional small punch grinding device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of small punch grinding, in particular to a multifunctional small punch grinding device. It is a small punch processing and maintenance tool for molds. It is placed on the worktable (disk) of the hand grinder, and it can be used for small punches of various shapes (such as round, square, other regular polygons, flat and elliptical) ) for grinding. Background technique [0002] Mold small punch processing and maintenance are often encountered in general factories. The small punch is small in size and requires special machining. This special-purpose mechanical structure is complicated, and cost is high, and general factory is uneconomical to purchase. [0003] In addition, there are currently some small punch grinders with simple structures, but they are only convenient for processing round punches, and are not convenient for processing punches of other shapes. The general regular polygon, ellipse and othe...
