A metal grinding device convenient for clamping workpieces

Abstract

The invention discloses a hardware polishing device capable of conveniently clamping a workpiece. The hardware polishing device capable of conveniently clamping the workpiece comprises transverse fixing plates, a first fixing side plate, a second fixing side plate, a fixing base and a rotating tooth roller. The two ends of each transverse fixing plate are connected with first sliding blocks through first rotating shafts, and the first sliding blocks are arranged on the first fixing side plate and the second fixing side plate. The bottom end of the second fixing side plate and the bottom end ofthe first fixing side plate are connected with second sliding blocks through hinge shafts. First elasticity springs are arranged between the fixing base and the transverse fixing plates. Moving grooves are formed in the second sliding blocks, and first transmission racks are welded on the second sliding blocks. The two ends of the rotating tooth roller are movably connected with the inner wall ofthe fixing base, and a first electric motor is arranged on the rotating tool roller. By the adoption of the hardware polishing device capable of conveniently clamping the workpiece, pipe fittings with different inner diameters can be firmly fixed, workers can conveniently conduct machining and polishing operation, the clamping effect is good, and the hardware polishing device capable of conveniently clamping the workpiece is simple in integral structure, convenient to operate and high in practicability.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to a hardware grinding device for clamping workpieces. Background technique [0002] Hardware: traditional hardware products, also known as "hardware". Refers to the five metals of gold, silver, copper, iron, and tin. Hardware includes plumbing fittings. After the existing plumbing fittings are processed, the surface will have burrs. In order to ensure the smoothness of the surface, it needs to be polished. [0003] The existing grinding device has low grinding efficiency, and it is easy to shake the pipe fittings during the grinding process, which affects the grinding effect, is not practical, and cannot meet people's use needs. Only by making improvements and making it more practical can it meet the actual usage conditions.
