As optimization, be provided with the frustum type cavity at the clamp body center, the cavity at the clamp body center is provided with the plum blossom briquetting; The plum blossom briquetting is the frustum type that cooperates with cavity; The plum blossom briquetting cooperates with the anchor clamps hole, runs through being provided with connecting rod at plum blossom briquetting center, and described rod head passes and draws dish to be connected with connecting rod; On the connecting rod that draws between dish and the plum blossom briquetting, be arranged with spacer ring, the connecting rod outer end is connected through tapering packing ring and nut and plum blossom briquetting.Utilize pull bar when drawing in locating piece, to draw in the plum blossom briquetting, the piston in the anchor clamps hole is clamped, prevent that piston from trickle rotation taking place, and influences the machining accuracy of spheric surface.
In order to realize earlier piston being compressed, draw dish and locating piece in pulling, be employed under the situation that pull bar does not stress; The length of spacer ring is less than the distance of drawing between dish and the plum blossom briquetting; Can be implemented in the pull bar drawing process, at first make the plum blossom briquetting, oppress spacer ring again and draw dish the compressing of piston; Realize that locating piece draws in the clamp body, prevent that further piston from trickle displacement taking place.
In order to prevent when draw-bar pull is big; The plum blossom briquetting is to the spacing tension in anchor clamps hole; Cause piston to be crushed out of shape even the situation of pressure break, be provided with groove in plum blossom briquetting outer side center, groove diameter is greater than the connecting rod diameter; Be arranged with stage clip on the connecting rod in groove, stage clip is spacing through the tapering packing ring.
The resulting piston spheric surface of the utility model processing unit (plant) utilizes the anchor clamps hole that piston is carried out same circumferential registration, utilize simultaneously the inner cambered surface of locating piece the piston spheric surface be positioned can realize time processing on the same circumference.The setting of length washer can guarantee that piston is in same axial location.It utilizes pull bar to drive and draws dish and locating piece, draws in clamp body inside to locating piece, and the spheric surface of piston is exposed; Can process it; The setting of the structure of plum blossom briquetting simultaneously when drawing in locating piece, guarantees that the plum blossom briquetting compresses piston; Avoid piston that trickle rotation takes place, thereby influence the machining accuracy of spheric surface.In addition, be provided with stage clip in plum blossom briquetting inside, can prevent when pulling force is big, the plum blossom briquetting causes piston distortion or damage to the spacing tension of piston.In addition on the one hand, rod head is not fixed with drawing between the dish, and utilizes the Design of length of spacer ring; Be implemented in the pull bar drawing process, at first realize the plum blossom briquetting, oppress spacer ring again and draw dish the compressing of piston; Realize that locating piece draws in the clamp body, prevent that further piston from trickle displacement taking place.
