Problems solved by technology

[0002] In order to improve the surface quality of shaft parts and reduce their surface roughness value, the terminal processing process of shaft parts is generally carried out on ordinary cylindrical grinding machines. For shaft parts with high surface quality requirements, the surface roughness value is very low. When the surface roughness value is lower than Ra0.025, it is difficult to use the traditional grinding process on ordinary cylindrical grinders to achieve its surface quality requirements

Abstract

The invention relates to a shaft part double-wheel symmetrical grinding device and process. The process includes: machining a workpiece on an excircle grinder to Ra0.40, leaving a machining allowance of 0.008-0.12mm, fixing a fixing piece during grinding, screwing a pressure-adjusting bolt compression spring, enabling grinding wheels to contact a workpiece surface to be ground, winding a lead screw, and enabling two grinding wheels to generate transverse feed; when the pressure of the spring on the workpiece is 2-3kg, stopping the transverse feed, starting a lathe, enabling the workpiece to rotate at the speed of 80-150 turns / minute, driving the two grinding wheels to rotate, starting a large carriage, enabling the large carriage to move vertically along a lathe track and drive the grinding wheels to move vertically together, controlling the moving quantity in the way that the grinding wheels move 2-3 mm vertically when the workpiece rotates a circle, washing through aviation gasoline till the workpiece surface roughness parameter meets the technical requirement, detaching the workpiece, and finishing grinding. The shaft part double-wheel symmetrical grinding device and process has the advantage that the process is simple, the roughness can be lower than Ra0.012, and efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a double-wheel symmetrical grinding device for shaft parts and its technology. Background technique [0002] In order to improve the surface quality of shaft parts and reduce their surface roughness value, the terminal processing process of shaft parts is generally carried out on ordinary cylindrical grinding machines. For shaft parts with high surface quality requirements, the surface roughness value The requirements are very low. When the surface roughness value is lower than Ra0.025, it is difficult to meet the surface quality requirements on ordinary cylindrical grinders using traditional grinding techniques. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a simple process, the roughness can reach below Ra0.012, high efficiency double-wheel symmetrical grinding device and its process ...
