Problems solved by technology
[0005] 1) The surface roughness of the contact part of the cylindrical workpiece and the oil seal is in accordance with GB1031-83, Ra is not greater than 0.63μm, not less than 0.2μm (▽7-▽9), the grinding wheel is not allowed to move axially during processing, which is difficult for conventional grinding machines To such a low roughness, it is necessary to use a high-precision grinder to grind the skeleton oil seal. The high-precision grinder equipment is more expensive, and the equipment cost is higher;
[0006] 2) When grinding, it is first necessary to align the workpiece and the worktable on the grinding machine, that is, to ensure the coaxiality of the workpiece and the worktable, the alignment efficiency is low and the time is wasted more

The invention relates to a grinding tool for a framework oil seal part. The grinding tool for the framework oil seal part comprises a clamping rod and oilstone, wherein a guiding piece is arranged between the clamping rod and the oilstone, and can drive the oilstone to move horizontally; the clamping rod can be directly arranged on a turning lathe and comprises a rod part and a head part; the headpart is provided with a cavity; a first spring rod is arranged on the bottom part of the cavity; the guiding piece comprises a second spring rod, a limiting boss and a sliding rod connected sequentially from back to front; the second spring column corresponds to the first spring column; springs sleeve the first spring column and the second spring column; an end cover is arranged at the front endof the cavity; and the sliding rod penetrates through the end cover so as to be connected with the oilstone. The invention further relates to a grinding method adopting the grinding tool. After the turning lathe finishes turning a workpiece, the grinding tool is arranged on the turning lathe, the turning lathe drives the workpiece to rotate, and the oilstone continuously grinds the framework oil seal part of the workpiece until the grinding requirement is met; and the turning lathe equipment cost is low, the equipment cost is saved, and the grinding efficiency is improved.
Description
technical field [0001] The invention relates to a grinding tool and a grinding method, in particular to a grinding tool and a grinding method for a skeleton oil seal part. Background technique [0002] In the prior art, the grinding of the oil seal part of the workpiece skeleton requires a grinding machine. During grinding, the oil seal part of the workpiece skeleton is ground with a grinding wheel on the grinding machine, and the workpiece is rotated at a low speed, so that the grinding wheel is used to grind the oil seal part of the workpiece skeleton. Grinding, the steps of grinding the skeleton oil seal part of the cylindrical workpiece are: firstly turn the workpiece on the lathe, after the processing is completed, remove the workpiece from the lathe, and then install it on the worktable of the grinding machine for grinding. machining; [0003] The cylindrical workpiece includes the cylindrical workpiece body and the annular boss formed integrally with the cylindrical ...
