Abstract

The invention discloses a method and a device for magnetically grinding the inner and outer ring grooves of a sealing sleeve part. The method includes: clamping the workpiece on the spindle chuck, installing the arc-shaped magnetic pole on the magnetic pole fixing rod of the grinding device, mixing the sintered magnetic abrasive with the water-based grinding liquid, filling it evenly in the processing gap, starting the lathe, The magnetic pole is fixed, the motor drives the spindle and the workpiece to rotate, and the inner and outer grooves are precisely ground; the sintered magnetic abrasive is replaced to perform ultra-precision grinding on the inner and outer grooves. The device consists of an ordinary lathe and a magnetic grinding mechanism. The magnetic grinding mechanism includes a longitudinal screw, a horizontal screw, an inner magnetic pole fixing rod, an outer magnetic pole fixing rod, an inner magnetic pole, an outer magnetic pole, magnetic abrasives, an adjusting gasket and a spindle chuck. The invention can set a reasonable spindle speed according to the accuracy requirement of the groove bottom, and grind and process the sealing sleeve parts with high efficiency and high quality.

Description

technical field [0001] The invention relates to a grinding and polishing method and a device thereof, in particular to a magnetic grinding method and a device for inner and outer ring grooves of a sealing sleeve part. Background technique [0002] The dimensional accuracy and surface quality of sealing parts (such as pistons) directly affect the service performance and life of the hydraulic mechanism. Due to the special structure of the pneumatic components in the automobile engine, higher requirements for dimensional accuracy, shape accuracy and surface quality are also put forward for the sealing parts. [0003] The sealing sleeve part is processed on a CNC lathe through multiple processes, and a large number of processing textures and burrs will inevitably remain on the surface of the workpiece. Because the inner and outer grooves of the part are narrow and the bottom of the groove is deep, traditional grinding tools are very difficult. Difficult to access, it is very di...
