Abstract

The invention discloses a planar rolling cutter with the constant distance rolling function. The planar rolling cutter comprises a shank part and a cutter body, wherein the shank part comprises a shank and a shank connecting block which are connected; an oil seal gasket is arranged between the shank and the shank connecting block; the cutter body comprises a cutter connecting cylinder and a rolling ball component positioned at the lower part of the cutter connecting cylinder; the shank connecting block is connected with a force bearing plate in the cutter connecting cylinder; the force bearing plate is in clearance fit with a sensor fixing seat; a force sensor is mounted inside the sensor fixing seat; the sensor fixing seat is connected with an electrostriction block; the electrostriction block is fixedly connected with a support seat; the support seat is fixedly connected with the rolling ball component; a proximity switch is mounted at the bottom of the rolling ball component. According to the invention, the proximity switch is additionally mounted at the bottom of the cutter, so that the distance between the cutter and a workpiece is kept constant during the rolling process, and constant rolling pressure during the rolling process is guaranteed, so that the rolling effect is improved.

Description

Technical field

[0001] The invention relates to the field of chipless processing, in particular to a flat rolling tool for constant distance rolling. Background technique

[0002] The rolling method is a kind of chipless processing, which can not only achieve a high finish, but also improve the mechanical properties of the processed parts. The essence of the rolling method is to use high-hardness bladeless tools-steel balls or rollers to cause local high pressure on the processed surface. As the tool rolls along the surface to be processed, elastic-plastic deformation of the surface material is formed, so that the microscopic peaks left on the surface in the previous process are smoothed, and a certain thickness of strengthening layer is formed on the surface. Due to the smooth surface and increased hardness, the wear resistance and fatigue strength of the parts are greatly improved.

[0003] The rolling cutter is connected to the main shaft of a milling machine and other machine...
