Gearbox shell body inner hole polishing device

Abstract

The invention relates to an inner hole polishing device, in particular to a gearbox shell body inner hole polishing device. According to the technical scheme adopted by the invention, the gearbox shell body inner hole polishing device comprises a workbench, a polishing motor, polishing bars and a gear box; supporting legs for supporting the workbench are arranged under the workbench; the workbench is provided with limiting columns; the polishing motor is installed in the position, above the workbench, of a fixing frame A; a motor shaft of the polishing motor is connected with the gear box; the multiple polishing bars are installed in installation holes of an upper fixing frame B, and the bottoms of the polishing bars are connected with a rotary shaft of an inner gear of the gear box; the lower portion of the workbench is connected with an air cylinder rod of the air cylinder; chip removing holes penetrating through the workbench are uniformly distributed in the workbench; and a chip collecting tank is arranged under the workbench. The gearbox shell body inner hole polishing device has the advantages that a plurality of inner holes in a gearbox shell body can be subjected to polishing treatment at the same time, the labor intensity of staff is relieved advantageously, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an inner hole grinding device, in particular to a gear box inner hole grinding device. Background technique [0002] The gearbox is an important precision part of the vehicle, which transmits the power and speed output by the engine to the hub through the distribution of the internal gear train to achieve different speeds and power outputs. The main function of the gearbox housing is to cooperate with the gearbox body to form a closed structure and provide necessary conditions for the lubrication of the moving parts inside the engine. The gearbox housing is usually integrally formed by aluminum alloy die-casting, and its shape is relatively complex, with many holes and surfaces, and the requirements for position and size are strict. There are many burrs on the edge and inner hole of the formed gearbox body. The existence of burrs will have a negative impact on the machining accuracy, assembly accuracy and appearance quality of...

AI Technical Summary

Problems solved by technology

In the existing grinding of the inner hole of the gearbox housing, most of the holes on the box body are polished one by one with manual hand-held grinding tools, which has a large workload and high labor intensity, and has high requirements for the operator.
