Description

Technical Field

[0001] The utility model relates to the technical field of grinding of bearing housing castings, and particularly relates to a grinding device for processing bearing housing castings. Background Art

[0002] Bearing housing castings are important parts in mechanical manufacturing, mainly used to support bearings and fix them on mechanical equipment. The quality and precision of bearing housings have an important impact on the performance and service life of mechanical equipment. Therefore, the casting process design of bearing housings is crucial, involving multiple aspects such as material selection, gating system design, and core design. The commonly used materials for bearing housings include two major categories: cast iron and cast steel. Cast iron has good casting performance and mechanical properties and is suitable for the manufacture of most bearing housings. Cast steel has higher strength and wear resistance and is suitable for bearing housings that bear large loads and rotate at high speeds. When selecting materials, comprehensive consideration needs to be given according to the usage conditions and requirements of the bearing housing.

[0003] When performing the grinding work on bearing housing castings, when grinding castings with different widths but the same length, the distances between the internal mounting holes of the castings are different, resulting in inaccurate installation and fixation and thus unable to perform grinding.

Then the motor is started, the motor drives the transmission rod to rotate, the transmission rod drives the fixing plate to rotate, and the fixing plate drives the grinding strip and the grinding plate to rotate to perform the grinding work on the surface of the bearing seat casting.
