Casting polishing tool

Abstract

The invention relates to the field of casting polishing, in particular to a casting polishing tool. The casting polishing tool comprises a positioning and polishing device and a bearing and clamping device; the positioning and polishing device comprises a worktable, a driving part and a polishing part; the bearing and clamping device comprises a support table, a clamping part and a clamping driving part; the polishing part comprises a bearing box, a rotating module and two polishing modules; the bearing box is mounted at the top of the worktable; the rotating module comprises a rotating disc,and a transmission rod mounted in the center position of the rotating disc; one end of the transmission rod extends into the bearing box; each polishing module is in transmission connection with the transmission rod; and in a working state, the clamping part is in butt joint with each polishing module. Through circular reciprocating rotation of the two polishing modules, castings to be polished can be continuously polished, so that the polishing efficiency is improved; and the castings are clamped through automatic equipment, and manual holding of the castings is prevented, so that the dangerof mechanical equipment to machining workers is prevented.

Description

technical field [0001] The invention relates to the field of casting grinding, in particular to a casting grinding tool. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, including steel castings, iron castings, copper castings, aluminum castings and other types. Castings are objects with a certain shape, size and performance obtained by injecting smelted liquid metal into a pre-prepared mold by pouring, injection, inhalation or other casting methods, after cooling, etc. [0003] When the casting is smelted and formed, in order to avoid defects in the casting, a riser is provided on the top or side of the casting, and its main function is to feed shrinkage. However, after the pouring is completed, the surface of the riser is not only raised but also very rough, so it is necessary to polish the surface of the casting. The existing grinding is mainly manual operation. When grinding, the casting is placed on the platform, and ...

AI Technical Summary

Problems solved by technology

However, after the pouring is completed, the surface of the riser is not only raised but also very rough, so it is necessary to polish the surface of the casting. The existing grinding is mainly manual operation. When grinding, the casting is placed on the platform, and then the riser is aligned with the grinding wheel for grinding. , this kind of grinding method mainly judges the depth of grinding manually, and the high-frequency vibration during grinding requires a lot of manual effort to control the casting, which is dangerous, and the efficiency and accuracy of grinding are not high
