Description

Surge type cleaning device for automobile rear axle housing

Technical Field

The utility model belongs to the technical field of automobile structural part cleaning devices, and particularly relates to a surge type cleaning device for an automobile rear axle housing.

Background

Automobile rear-axle housing cleanliness concerns the operational reliability of rear axle assembly, and current rear-axle housing cleaning machine mainly includes two kinds: one is step-by-step through spray type axle housing cleaning equipment, although the fixed-point positioning of high-pressure water flow for spraying the inner surface and the outer surface of an axle housing can be realized, the cleaning effect of the sprayed part is ideal, but the spraying part is limited by the structure of an inner cavity of the axle housing, the cleaning effect of the inner cavity is poor, the fixed-point positioning is only suitable for cleaning the axle housing of a single variety or a small variety, and the requirement on the cleanliness of the inner cavity of the axle housing in batches of various varieties cannot be met; another kind is ultrasonic wave axle housing cleaning equipment, though can realize that many varieties mix production of line, but the input cost is high, and use cost is also high, though peel off impurity through the ultrasonic wave, nevertheless receives the influence of axle housing inner chamber structure, has to shelter from position impurity and can not effectively come out, and production efficiency is not high, and the cleaning performance is not ideal enough yet, for this reason, needs one kind to drop into and use cost is low, production efficiency is high and the good axle housing belt cleaning device of cleaning performance.

In order to solve the above problems, in "a high cleanliness car axle housing inner chamber cleaning special machine" with patent publication number CN 208495244U, the disclosed structure is: seamless steel pipe, water inlet hose and brush head, the outer end of seamless steel pipe is connected with water inlet hose, and be equipped with speed adjusting mechanism on the water inlet hose, the input fixedly connected with and the seamless steel pipe assorted connecting pipe of brush head, the connecting pipe is inserted and is established the one end that the seamless steel pipe kept away from water inlet hose, and connecting pipe and seamless steel pipe sliding connection, set up two symmetrical draw-in grooves on the lateral wall of connecting pipe, the sliding tray has been seted up to the position department that the inner wall of seamless steel pipe corresponds the draw-in groove, the tank bottom fixedly connected with spring of draw-in groove, the other end fixedly connected with and the draw-in groove assorted fixture block of spring, and draw-in groove and fixture block sliding connection. Although this technical scheme can solve the poor problem of current automobile axle housing inner chamber cleanliness, has advantages such as guaranteeing whole bridge cleanliness, nevertheless, because it drives the brush head through speed adjusting mechanism and moves at the axle housing inner chamber, so it only can realize inner chamber axle housing pipe cleaning in the structure that the axle housing inner chamber does not have the sheltering from, can't accomplish the continuous self-cleaning that has complicated structure such as sheltering from to the automobile rear-axle housing inner chamber, and production efficiency is low, is unsuitable for batch serialization production.

In "surge upset cleaning machine" of notice number CN 204035082U, the technical essential of record is: the cleaning chamber is provided with a speed reducer with a turnover frame, two sides of the cleaning chamber are provided with cylinder sealing doors, a cylinder cover on the turnover frame is locked through a locking cylinder, the turnover frame with the cylinder cover rotates and turns at a constant speed at the speed reducer when the cleaning chamber is in a closed state, a cleaning water pump is started, cleaning pressure is set, cleaning liquid is sprayed on the cylinder cover, the liquid level in the cleaning chamber gradually rises to reach the center height of the cylinder cover, and the cylinder cover is in a surging cleaning state in the cleaning liquid; then the cleaning pump is closed, the cleaning liquid completely flows back to the cleaning liquid storage tank by opening the cleaning bottom valve, and the draining is delayed to ensure that the cleaning liquid is discharged completely to reduce liquid channeling; and then opening a rinsing bottom valve, setting rinsing pressure, starting a rinsing pump, finishing a surge overturning and cleaning process in the cleaning chamber, spraying and rinsing the cylinder cover, filtering rinsing liquid after rinsing is finished, closing the rinsing bottom valve, opening a pneumatic door and a paint mist condenser, dripping mist condensate water into a return water tank, pulling out the cylinder cover from the cleaning chamber after drying, and finally manually holding a compressed air spray gun to blow water to the cylinder cover. However, although the surge overturning cylinder cover cleaning method in the technical scheme can clean the cylinder cover in an overturning cylinder cover and a surge mode, the cleaning and rinsing share one cleaning chamber, so that secondary pollution is easily caused, the production efficiency is low, and the method is not suitable for batch continuous production.
