Abstract

The invention relates to a super-finishing roller structure. The super-finishing roller structure comprises a hollow roller body and journals, wherein the journals are connected to the inner sides ofthe two ends of the roller body; the roller body is in clearance fit with the journals; gaps are internally filled with glue; and the amount of clearance between the journals and the roller body is 0.05-0.07mm. The super-finishing roller structure has the beneficial effects that the risk of quenching cracks of workpieces caused by forging defects of workblanks can be lowered, assembling operationcan be convenient, and the problem of stress cracks of the workpieces caused by interference fit can be solved.

Description

technical field

[0001] The invention relates to a superfinishing roll structure. Background technique

[0002] The superfinishing roller is an important tool for finely grinding the outer circle of the roller. In order to ensure the quality of the roller being ground, it must have high machining accuracy and wear resistance. The processing precision of the super-finishing roller is very high, and the coaxiality of the bearings at both ends is required to be high, so the processing is difficult and difficult. Contents of the invention

[0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a superfinishing roll structure.

[0004] A technical solution adopted by the present invention to solve the technical problem is: a superfinishing roll structure, including a hollow roll body and journals connected to the inner sides of both ends of the roll body, the gap between the roll body and the journal i...

Examples

Embodiment Construction

[0009] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0010] Such as figure 1 The superfinishing roller structure shown includes a hollow roller body 1 and a journal 2 connected to the inner sides of both ends of the roller body 1. The roller body 1 and the journal 2 have a clearance fit, and the gap is filled with glue. The journal 2 and the roller The gap between bodies 1 is 0.05-0.07mm.

[0011] Heat treatment can be performed on the roller body 1 and the journal 2 separately, which solves the problem that the hardness gradient is difficult to guarantee.

[0012] To a certain extent, the risk of workpiece quenching cracking caused by blank forging defects is effectively reduced. The roll body 1 is changed from the original solid structure to a hollow cylindrical structure with a certain wall thickness, w...
