Excircle surface rolling device

Abstract

The invention discloses an outer circle surface rolling device including a fixing main body. An inner ring at one end of the fixing body is rotatably cooperated with a steel drive sleeve that can drive power and the other end of the fixing body is screwedly connected with a shell. A screw thread in the shell is connected with a mandrel; the output end of the steel drive sleeve drives a protectingsleeve, a surrounding circle of which is embedded with a roller pin through a discrete drive sleeve and the protecting sleeve is inserted in a central hole located in the mandrel; a tip spring sleeved on an outer ring of the protecting sleeve is compressed between the inner end surface of the mandrel and the discrete drive sleeve; an inner hole of the steel drive sleeve is provided with a plasticdrive sleeve that can adjust and maintain the expansion amount of the sleeve and collocated with the dimension adjusting and locking functions of the mandrel and an adjusting spring as well as a spring pressure sleeve arranged n the plastic drive sleeve, thus realizing the coarse adjustment and micro-adjustment on the rolling parts with various dimensions; a through hole is arranged in the steel drive sleeve and the protecting sleeve and has no length depth position limiting; the processing length of the rolling parts are not restrained; a blocking connecting torque force is stably transferred; the invention adopts a diagonal roller pin structure and has accurate dimension processing.

Description

technical field [0001] The invention relates to the technical field of surface treatment equipment in mechanical processing, in particular to an outer circular surface rolling device, which is suitable for rolling the surface of long rods. Background technique [0002] In general, centerless grinding is used for the automatic feeding of outer cylindrical rolling, and its processing length is limited and cannot be extended without limit; in general grinding, compared with surface rolling processing, the processed outer cylindrical surface The smoothness is not enough, and the wear resistance and hardness are not high, and there is industrial waste after cutting. [0003] It is better to adopt the surface rolling method, such as the Chinese utility model patent "Rolling Device for the Outer Circle Surface of Shaft Workpieces" (notification number CN2741709Y) whose patent number is 200420063824.5; , the roller sleeve has a built-in roller clamped by a cylindrical cage, and bot...

AI Technical Summary

Problems solved by technology

The contact rolling between the roller and the surface of the workpiece can produce better processing effect, but the adjustment of the inner processing size of the roller is unstable, and the adjustment operation is inconvenient; moreover, the vertical roller structure has a long contact surface , it is difficult to achieve precision surface processing of rolled parts
