Problems solved by technology

The differential housing is generally welded by the combination of the left and right housings. The joint surface will inevitably have some burrs, which need to be polished, but the traditional polishing machine is difficult to achieve Reasonable, multi-directional polishing of the differential case, uneven polishing work, can not effectively remove burrs, so that the life and utilization rate of the differential case will be greatly reduced

Abstract

The invention discloses differential mechanism housing surface polishing equipment which comprises a box body, wherein a polishing chamber is formed in the box body; a stock bin is arranged at the bottom of the polishing chamber; an air cylinder is arranged at the top center of the polishing chamber; a housing is fixedly connected with the output end of the air cylinder; a first motor is fixedly connected with the interior of the housing; and a connecting sleeve is fixedly connected with the output shaft of the first motor. According to the differential mechanism housing surface polishing equipment, the differential mechanism housing is fixedly mounted through the connecting sleeve to adjust the length of the output end of the air cylinder, the output end of the first motor is in transmission connection with the connecting sleeve to rotate the differential mechanism housing in polishing sand, a third motor is in transmission connection with a guiding wheel to enable the polishing sandto enter a lifting cavity from a channel, the output end of a second motor is in transmission connection with a screw rod, the screw rod lifts the polishing sand up, the polishing sand sprays out of an upper channel to act on the top of the differential mechanism housing, and the motors are in in transmission connection with gears to enable two stirring wheels to rotate relatively so as to improvethe moving activity of the polishing sand, so that reasonable and multidirectional polishing on the differential mechanism housing is realized and the polishing quality is improved.

Description

technical field [0001] The invention relates to the field of component polishing equipment, in particular to a surface polishing equipment for a differential case. Background technique [0002] The differential is a very important part of an electric vehicle. It is a mechanism that enables the left and right or front and rear drive wheels to rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear rack. Its function is to drive the car when turning. Or when driving on uneven roads, make the left and right wheels roll at different speeds, that is, to ensure the pure rolling motion of the driving wheels on both sides, and the differential is installed to adjust the speed difference between the left and right wheels, so the differential is a kind of Parts that require high precision. The differential housing is generally welded by the combination of the left and right parts of the housing, and the joint surface will i...
