Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an axle housing washer.

[Conventional technology]

Conventionally, the cleaning of the inside of the housing has been blown out with compressed air.

[Problems to be solved by the device]

Since a lot of dust and chips are contained in the housing,
Although it was blown off with compressed air, it could not be cleaned sufficiently and a large amount of dust and chips remained. Also, the housing has a poor mass balance and is difficult to handle. An object of the present invention is to solve the above-mentioned problems and to provide a housing cleaning machine capable of cleaning the inside by flowing a cleaning liquid inside while rotating.

[Means for Solving the Problems]

The axle housing washer of the present invention is for cleaning the inside of an axle housing having an opening at the center with a washing liquid, and a support drive device for supporting tubes at both ends of the axle housing by three rotating rollers rotated by a geared motor. A nozzle device that discharges the cleaning liquid to the tube holes at both ends, a cleaning liquid circulating device that supplies the cleaning liquid to the nozzle device, and a table that mounts at least one of the support drive device and the nozzle in the axial direction of the axle housing. It is characterized by having a moving device, a liquid tank for receiving drainage, and a cover for covering the upper surface of the axle housing.

[Action]

After turning the pinion with the handle 23 to feed the rack and move the moving table 3 to adjust the position of the roller of the rotating device on the table to the tube length near the end of the axle housing, two receiving rollers and one presser foot Hold the axle housing with rollers. Then, the compressed air is sent to the pneumatic cylinder of the nozzle device to move the nozzle device, and the nozzle is fitted into the inner diameter of the opening of the tube at the end of the axle housing and pressed. If the electric pump of the cleaning liquid circulating device is driven to flow the liquid into the axle housing through the nozzle, and the roller of the rotating device is rotated by an external force to rotate the axle housing and rotate the axle housing while flowing the liquid inside. , Its inside can be cleaned sufficiently clean.
