Abstract

A grinding and polishing auxiliary device installed on an angle grinder comprises a handheld auxiliary frame and a limiting frame which are installed on the angle grinder in a matched mode. The handheld auxiliary frame comprises an extension pipe (1), a C-shaped limiting clamp (2) and mounting holes (2a) formed in clamping plates on the two sides of the C-shaped limiting clamp. The limiting frame comprises a groove-shaped support (3) and limiting idler wheels (4) symmetrically installed in two side plates of the groove-shaped support, through holes for assembling installation bolts (5) are formed in the two side plates of the groove-shaped support, the limiting idler wheels are installed on a groove-shaped idler wheel frame (6), and a fixing clamping ring (10) with the center line parallel to the center line of the idler wheels is welded to one side of the groove-shaped support. The C-shaped limiting clamp is clamped at the position of a machine head of the angle grinder, and the fixing clamping ring is arranged on a mounting base of a grinding wheel protective cover of the angle grinder in a sleeving mode. During grinding and polishing, the working efficiency can be effectively improved, the operation risk is reduced, the structure is simple and reliable, the operation is convenient, and the device is light and portable.
