| 1 | Method for machining shoe pocket for piston in variable displacement swash plate type compressor | US09655661 | 2000-09-06 | US06488454B1 | 2002-12-03 | Hew Nam Ahn; Young-seop Yoon |
| A method for machining a pair of shoe pockets for piston in a swash plate type compressor is disclosed. In this method, the shoe pockets are respectively formed on the opposed walls of the slot in the piston of the compressor while conforming to a single imaginary sphere. The method comprises the step of moving a cutter provided with an arc-shaped cutter blade that has a rotation diameter less than the width of the slot. Thereafter, there is performed the step of relatively revolving the cutter with regard to the piston by allowing the central axis of a revolved part to move along a circular orbit within the slot while rotating the cutter, so as to cut the shoe pockets to conform to the single imaginary sphere. Finally, the step of retreating the cutter out of the slot when the cutter completes one round revolution and is returned to its initial position is performed. | ||||||

| A spherical cutter includes a spherically shaped body having open and closed ends defining a central cavity, multipoint cutting edges disposed along a circular rim at the open end, and the spherically shaped body generally defined by a radius and an origin. The cutting edges may be provided on cutting inserts removably attached to support teeth circumferentially disposed along the rim. The spherical cutter may be mounted to a rotatable spindle of a multi-axis computer numerically controlled machine with the radius and the origin located along a rotational axis of the spindle. The machine may be used for machining a cylindrical blank to form a plurality of circumferentially spaced apart integral rotor blades extending radially outwardly from a hub by machining each of the slots along a spherical surface defined by the radius and the origin. | ||||||

| PROBLEM TO BE SOLVED: To provide a method for machining a shoe pocket to lay, on the contact face of the piston of a swash plate type compressor and the swash plate, a shoe for reducing a friction force between the above respective contact faces and also receiving the tilt angle displacement of the swash plate surface with the piston. SOLUTION: This method comprises transferring, into a space receiving the swash plate in the piston, a cutter which has an arc-shaped cutting blade having the same curvature as a virtual sphere formed by the shoe and rotates around the axis in a width direction of the piston as a rotating axis, and then rotating the cutter and revolving the rotating axis of the cutter along the round orbit in the swash plate-receiving space to perform the cutting for making the shoe pocket on both side inner walls of the swash plate-receiving space. | ||||||

| PURPOSE: A compressor piston processing method is provided to significantly reduce reject ratio and manufacturing cost by improving accuracy of an oblate spheroid groove. CONSTITUTION: A method for processing oblate grooves for insertion of a pair of oblate spheres loaded into both inner walls of a groove of a piston so as to form a virtual sphere, comprises a first step of transporting a cutter with an arc-shaped blade having a rotational diameter smaller than the width of the groove into the groove, a second step of rotating the cutter entered into the groove and simultaneously allowing the rotation axis of the cutter to revolve along a circular track within the groove as a relative movement with respect to the piston, so that the cutter sequentially cuts both inner wall surfaces of the groove according to the direction of the revolution of the rotation axis so as to process oblate grooves at the both inner wall surfaces of the groove, and a third step of transporting the cutter which is returned to an original position after completion of the cutting process of the second step, toward an outside of the groove. | ||||||

| 본 발명은 자동차 공기조화장치의 사판식 압축기에서 사판에 끼워져 사판의 회전에 따라 실린더 블록내에서 왕복동되어 냉매를 가압하는 압축기 피스톤을 가공하기 위한 압축기 피스톤 가공방법에 관한 것으로, 특히, 상기 피스톤과 상기 사판의 접촉면에서 이들 사이의 마찰력을 감소시킴과 동시에 피스톤이 사판 표면의 경사각 변위를 수용하도록 하기 위해 개재되는 편구(偏球)가 안치되는 편구홈 가공방법에 관한 것이다. 본 발명에 따른 압축기 피스톤 가공방법은, 피스톤의 요홈 양측 내벽면에 편구가 각각 안치되어 하나의 가상구(假想球)를 이루는 한 쌍의 편구가 안치되는 편구홈을 가공하기 위한 것으로서, 편구에 의해 형성되는 가상구와 동일한 곡률의 원호형 절삭날을 갖고 상기 피스톤 너비방향의 축을 회전축으로 하여 회전되는 커터를 상기 피스톤 요홈 내로 이송한 후, 상기 커터를 회전시킴과 동시에 상기 피스톤에 대한 상기 커터 회전축의 상대위치가 상기 요홈 내부의 원형 궤도를 따라 공전시킴으로써 상기 요홈 양측 내벽에 각각 편구홈을 절삭가공하는 것을 특징으로 하며, 이와 같은 특징에 따라, 나란한 방향의 자전축과 공전축을 갖는 두 개의 회전운동만으로 이루어진 절삭 커터로 피스톤의 편구홈을 가공하므로, 편구홈에 대한 가공치수의 정밀도를 크게 향상할 수 있다. | ||||||
