A device for removing iron filings in the inner cavity of the rear axle housing

Abstract

The invention relates to a device for removing iron filings in an inner cavity of a rear axle shell. The device comprises a supporting frame, a positioning mechanism, striking air cylinders and an electrical control system. The positioning mechanism is fixedly connected with the supporting frame. A pair of positioning nylon blocks are symmetrically arranged on the portions, relative to the center of the positioning mechanism, of the positioning mechanism, the nylon blocks and the positioning mechanism are connected in a sliding mode, and the striking air cylinders are symmetrically arranged on the supporting frame. Corresponding space between the positioning nylon blocks and the rear axle shell is positioning space, and corresponding space between the striking air cylinders and the rear axle shell is striking space. Due to the adoption of the impact air cylinders, the striking application range can be remarkably increased, and in other words, effective striking can be achieved in the stroke ranges of the impact air cylinders. By the combination of the electrical control system, striking frequency is adjusted through a panel, the impact strength is large, and the iron filing removing effect is good.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a device for removing iron filings in a rear axle housing cavity, in particular to a pneumatic device for removing iron filings in a rear axle housing. Background technique [0002] As a pillar industry, the automobile industry requires a large number of related accessories to be produced in various places. As for the car drive rear axle, its shell is generally welded by pressing and forming steel parts to form a certain cavity for assembling corresponding motion actuators, such as half shafts, reducers, differentials, etc. Therefore, the rear axle The axle housing needs to be machined to meet the assembly requirements. Due to the semi-closed lumen structure, a large amount of iron filings generated during processing cannot be removed and remain in the inner cavity such as dead corners. If this is the case, then after loading, it will shake out with the movement of th...

Problems solved by technology

Due to the semi-closed lumen structure, a large amount of iron filings generated during processing cannot be removed and remain in the inner cavity such as dead corners. If this is the case, then after loading, it will shake out with the movement of the car and enter In the oil circuit or transmission device, such as in the gear, there will be abnormal noise, wear and other quality problems that affect the use of the car

It has been verified that conventional vibrating chip removal and ultrasonic cleaning have a limited effect on removing iron filings; however, air shovels and electric hammers have a good effect on removing iron filings by directly hitting the rear axle housing. The positioning requirements are relatively high. If the chip is removed simply by direct hitting, the shape or positioning of the rear axle housing product will change greatly. When the difference changes greatly, it will be difficult to meet the assembly requirements, which will lead to product failure.
