Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a positioning device for processing a bearing seat. Background Art

[0002] Bearing seats are common parts in mechanical equipment. Their processing technology is an important part of mechanical processing. The main processing technologies of bearing seats include milling, drilling, grinding, stamping, etc.

[0003] In actual production, the shaft hole is processed first and then the base is processed. The bearing seat is fixed by a chuck. When processing the base, the chuck needs to be aligned with the center of the shaft hole of the bearing seat to ensure the center height requirement of the bearing seat.

[0004] It has been found in actual production that the existing positioning of the bearing seat has the following deficiencies:

[0005] In the existing process, when processing the base, the axis center of the shaft hole and the center of the chuck need to be aligned before the base can be processed. However, when the base is fixed, the axis centers of the shaft holes are different due to the different sizes of the bases to be processed, so it is necessary to constantly align with the center of the chuck and make adjustments, which easily affects the alignment and makes it impossible to guarantee the overall alignment accuracy.

[0006] In addition, when processing the base of each bearing seat, since the dimensions of the bearing seats before processing are different, after processing, the processed bearing seats are removed, and the bearing seats need to be re-aligned before processing the next group of bearing seats, resulting in the need to align them one by one. As a result, when the bearing seats are mass-produced, the alignment of the bearing seats takes a long time, affecting the overall processing efficiency;

[0007] Therefore, the present application provides a positioning device for bearing seat processing to meet the needs. Utility Model Content
