Handheld burr removing device for casting machining

Abstract

The invention discloses a handheld burr removing device for casting machining. The device comprises a machine shell, a sliding groove is formed in one side of one end of the machine shell, a sliding block is arranged in the sliding groove, a transverse grip extending out of the sliding groove is arranged at one end of the sliding block, an arc-shaped protective cover is jointly arranged at the two ends of the outer side of the transverse grip, a through groove is formed in the top of the sliding groove, and a transmission bin is arranged on one side of the interior of the machine shell. A driving shaft is driven to rotate through driving of a driving motor, then a grinding piece is driven to conduct grinding under transmission of a spiral gear and a spiral bevel gear, meanwhile, blades are driven to rotate through rotation of the driving shaft, external air is sucked from a through hole in one end of a machine shell through rotation of the blades, and after the driving motor is cooled, hot air flow is discharged from the through hole in the other end of the machine shell, so that the function of cooling the interior of the machine shell is achieved.

Description

technical field [0001] The invention relates to the technical field of casting processing, in particular to a hand-held deburring device for casting processing. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , The obtained object has a certain shape, size and performance. When the existing casting is produced, more burrs will be generated, so it needs to be polished, and then a grinding device is used. [0003] Most of the existing casting deburring devices are grinders, and the structure of the existing grinders is relatively mature, but in actual use, the internal motor of the grinder runs for a long time, thereby generating a large amount of heat. The increase makes the internal temperature rise, resulting in excessive ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hand-held deburring device for casting processing to solve the problem that the existing casting grinding and deburring device in the above-mentioned background technology will be damaged due to excessive heating of the internal drive motor when it is used. , at the same time, it is equipped with a horizontal handle bar on the outside, which cannot adjust its position and lacks the problem of its protection
