Turning and grinding tool for inner holes of bearing seat

Abstract

The invention discloses a turning and grinding tool for inner holes of a bearing seat. The turning and grinding tool comprises a connecting flange plate, further comprises V-shaped iron fixed on the connecting flange plate, and further comprises a pressing plate. One side of the V-shaped iron is tightly attached to the connecting flange plate, and the other side of the V-shaped iron is provided with a V-shaped downward-sunken structure; the bearing seat is placed in the downward-sunken structure of the V-shaped iron; and the pressing plate is fixed to the connecting flange plate and fixes thebearing seat to the position between the V-shaped iron and the pressing plate. According to the turning and grinding tool, turning and grinding are adopted jointly, a bearing seat bulged key is reliedfor positioning, the slopes of the two sides of the bearing seat are relied to serve as compressing faces, in the machining process, the peripheries of the holes are not affected by clamping force and cutting force, and after the workpiece is unloaded, the bearing holes do not deform.

Description

technical field [0001] The invention relates to a universal shaft coupling, in particular to a tool for grinding the inner hole of a bearing seat. Background technique [0002] In the field of cardan shaft couplings, the bearing seat is a key part, which is characterized by complex structure, thin wall thickness, and requires carburizing and quenching treatment. This part has multiple bores that need to be machined. However, the precision of the inner hole of the part is very high, and the roughness requirement is higher, reaching Ra 0.4μm, especially the position of the inner hole, the requirements are more stringent. The high processing requirements of the parts make it difficult to fix and position the parts during production, especially in the process of turning the inner hole and grinding the inner hole, resulting in insufficient machining accuracy and insufficient position of the inner hole. [0003] There are also some tooling used for fixing and positioning in the ...

AI Technical Summary

Problems solved by technology

The high processing requirements of the parts make it difficult to fix and position the parts during production, especially in the process of turning the inner hole and grinding the inner hole, which will result in insufficient machining accuracy and insufficient position of the inner hole

[0003] There are also some tooling used for fixing and positioning in the prior art. However, because the bearing seat has the characteristics of thin wall thickness, that is, the workpiece is a thin-walled part, and its requirements for clamping force are also very high. The tightening force will cause damage to the workpiece itself, and even cause deformation of the workpiece.
