Abstract

The present invention belongs to the field of machinery, and is especially one kind of blind screw hole cleaning machine. The blind screw hole cleaning machine includes frame, water tank, centrifugal pump, water jetting system, etc. The water tank is connected through water inlet pipe to the water inlet of the centrifugal pump, the centrifugal pump is connected through connecting water pipe to the water inlet of a T-valve assembly, and the T-valve assembly has water outlet connected to the water jetting system, water returning port connected to the water tank, and valve core with port connected to the water outlet or the water returning port and connected to the control handle. The present invention has simple operation, no environmental pollution and high production efficiency.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment and relates to an internal thread blind hole cleaning machine. Background technique [0002] With the development of the automobile industry, the cleanliness of the drive axle assembly is getting higher and higher. The main reducer housing is an important part of the drive axle assembly. The material used is ductile iron—QT450-10, and the iron filings are in the form of The particle powder is in the form of powder, which has stronger adhesion after mixing with cutting fluid and is more difficult to remove. Therefore, the cost of improving the cleanliness of the drive axle assembly will increase accordingly. On the premise of considering reasonable cost, how to improve the cleanliness of the final drive housing is a difficult problem in the prior art. The manual cleaning method has poor effect, unreliability and very low efficiency; the vibration method is difficult to meet the clean...
