As optimization, be provided with cavity at clamp body center, be provided with plum blossom briquetting at the cavity at clamp body center, plum blossom briquetting is the frustum type coordinating with cavity, plum blossom briquetting coordinates with fixture hole, runs through and is provided with connecting rod at plum blossom briquetting center, and described rod head is connected with connecting rod through pulling plate, on the connecting rod between pulling plate and plum blossom briquetting, be arranged with spacer ring, connecting rod outer end is connected by tapering packing ring and nut and plum blossom briquetting.Utilize pull bar in drawing in locating piece, plum blossom briquetting to be drawn in, the piston in fixture hole is clamped, prevent that piston from trickle rotation occurring, and affects the machining accuracy of spheric surface.
In order to realize first, piston is compressed, pulling pulling plate and locating piece, adopt in the situation that pull bar does not stress, the length of spacer ring is less than the distance between pulling plate and plum blossom briquetting, can realize in pull bar drawing process, first make the compression of plum blossom briquetting to piston, then oppress spacer ring and pulling plate, realize locating piece and draw in clamp body, further prevent that piston from trickle displacement occurring.
In order to prevent in the time that draw-bar pull is larger, the spacing tension of plum blossom briquetting to fixture hole, cause the piston even situation of pressure break that is crushed out of shape, be provided with groove in plum blossom briquetting outer side center, groove diameter is greater than connecting rod diameter, on connecting rod in groove, be arranged with stage clip, stage clip is spacing by tapering packing ring.
The piston anti-rotation surface processing device that the present invention obtains, utilizes fixture hole to carry out same circumferential registration to piston, the cambered surface of simultaneously utilizing locating piece inside anti-rotation surfaces of pistons be positioned on same circumference, can realize time processing.The setting of length washer, can ensure that piston is in same axial location.It utilizes pull bar to drive pulling plate and locating piece, locating piece is drawn in to clamp body inside, the spheric surface of piston is exposed, can process it, the setting of the structure of plum blossom briquetting simultaneously, in drawing in locating piece, ensures that plum blossom briquetting compresses piston, avoid piston that trickle rotation occurs, thereby affect the machining accuracy of spheric surface.In addition, be provided with stage clip in plum blossom briquetting inside, can prevent in the time that pulling force is larger, plum blossom briquetting, to piston limit tension, causes piston distortion or damages.One side in addition, does not fix between rod head and pulling plate, and utilizes the Design of length of spacer ring, realize in pull bar drawing process, first realize the compression of plum blossom briquetting to piston, then oppress spacer ring and pulling plate, realize locating piece and draw in clamp body, further prevent that piston from trickle displacement occurring.
