Device for coping notch joint surface of piston ring

Abstract

The invention provides a device for coping a notch joint surface of a piston ring. The device comprises a workbench (1), a crossed sliding seat, a motor case (6) and a distribution box (7), wherein the crossed sliding seat, the motor case (6) and the distribution box (7) are mounted on the workbench (1). A motor and a spindle driven by the motor are arranged in the motor case (6), the spindle horizontally extends out of the motor case (6), and a grinding wheel (4) is mounted at the tail end of the spindle. A controller electrically connected with the motor is arranged in the distribution box (7). The crossed sliding seat comprises a first sliding seat (21) slidably connected with the workbench (1) and a second sliding seat (22) slidably connected with the first sliding seat (21), a pistonring mounting seat (5) is mounted on the second sliding seat (22), and an inclined surface with a 45-degree dip angle relative to the horizontal plane is arranged at the top end of the piston ring mounting seat (5). The device further comprises a piston ring clamp used for fixing the piston ring on the inclined surface. By utilizing the device, the notch joint surface of the piston ring can be coped more simply and conveniently, and moreover, coping efficiency and yield can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a device for grinding the notch joint surface of an expanding ring. Background technique [0002] The torsion measuring oil cylinder with the expansion ring needs to be tested for flow rate, and the oil leakage is usually required to be no more than 0.2L / min. If it is unqualified, it can be adjusted by replacing the expansion ring. If the oil leakage is qualified, replace the new expansion ring directly. , then it will cause the replacement of the old ring to be scrapped and increase the repair cost. like Figure 5 As shown, the amount of oil leakage is determined by the joint surface of the notch 81 of the expansion ring 8 (that is, the two opposite inclined surfaces at an angle of 45 degrees). The roughness of the joint surface of the notch 81 is required to be 3.2. In order to save repair costs , the two joint surfaces can be ground, but at present, it is mainly repaired by ...
