Automobile casting grinding and polishing device

Abstract

The invention belongs to the field of automobile parts processing, and particularly discloses an automobile casting grinding and polishing device. An oil coating part comprises a rotary shaft and a support rod; a driving gear is fixedly connected to the lower end of the rotary shaft; an inner gear ring meshing with the gear is slidably connected to the lower end of the support rod; an annular sponge layer is arranged on an outer wall of the inner gear ring; a first piston barrel with two sealed ends is fixedly connected to the lower end of the driving gear; a clamping part comprises push rodsslidably connected onto a rack; clamping claws are hinged to one ends, far away from the push rods, of connecting rods; a grinding part comprises annular air blowing covers arranged in the push rods;the lower ends of the air blowing covers are fixedly connected onto the rack; the grinding part further comprises a second piston barrel fixedly connected onto the rack; two ends of the second pistonbarrel are sealed; a second piston is slidably connected into the second piston barrel; a second piston rod is fixedly connected to the upper side of the second piston; and a second grinding head is arranged at the upper end of the second piston rod. By adopting the technical scheme provided by the invention, the problem that after casting burrs are roughly cleaned, iron scraps are further neededto be cleaned manually is solved.

Description

technical field [0001] The invention belongs to the field of automobile parts processing, and in particular relates to a grinding and polishing device for automobile castings. Background technique [0002] Automobile castings refer to pouring smelted liquid metal into pre-prepared molds by pouring, injection, inhalation or other casting methods, and after cooling, they are polished and other subsequent processing methods. The obtained products have certain shape, size and performance. parts for automobile manufacturing. [0003] During the processing of automotive castings, the burrs generated will have adverse effects on many aspects such as the machining accuracy, assembly accuracy, processing positioning and appearance quality of the castings. Therefore, it is more and more important to polish the burrs of the castings. Whether it is manual grinding or machine grinding, the burrs on the casting are usually roughly cleaned by friction, and then the surface of the casting ...
