The utility model discloses the rhombus locating pin is provided with the screw thread with the bottom of circular locating pin, and the rhombus locating pin runs through the anchor clamps body with circular locating pin installs fastening nut respectively, and the locating pin is not extracted when guaranteeing to unload the part from anchor clamps. The utility model discloses arrange rhombus locating pin and circular locating pin along the horizontal line that the backup pad symmetric distribution is arranged along the diagonal with traditional locating pin and is compared in the both sides of rhombus locating pin with circular locating pin line, has reduced the manufacturing degree of difficulty of anchor clamps and debugged the degree of difficulty.
Description
Technical field
The utility model relates to a kind of part processing unit (plant), is specifically related to a kind of case of transmission fixture.
Background technology
Existing case of transmission class part is adding man-hour requirement use case of transmission fixture, traditional case of transmission fixture use holes is farthest as dowel hole, general employing is diagonally arranged, there is error accumulation phenomenon in manufacture process, and when horizontal Machining centers uses, the position of two pins is difficult to centering, causes part to be processed and there is error.Meanwhile, when unloading part from fixture, easily pin is extracted, cause the pore volume in chuck body easily to occur damage.
Utility model content
The purpose of this utility model is for above-mentioned defect of the prior art, and provide a kind of structure simple, easy to process, the easy centering in position of pin, clamps reliable case of transmission fixture.
To achieve these goals, the technical solution adopted in the utility model is:
Comprise chuck body and be arranged on the diamond positioning pin in chuck body, circular alignment pin and several gripper shoes; Described diamond positioning pin and circular alignment pin are arranged along horizontal line, and gripper shoe is symmetrically distributed in the both sides of diamond positioning pin and circular alignment pin line, and gripper shoe coordinates diamond positioning pin and circular alignment pin jointly to form the fixed space of fixture.
The both sides of described diamond positioning pin and circular alignment pin line are provided with four gripper shoes altogether, and the line of two gripper shoes compositions of every side and diamond positioning pin and circular alignment pin place straight line parallel.
Described gripper shoe is rectangle, and faced by the long limit of gripper shoe and fixed space.
Described gripper shoe is fixedly mounted in chuck body by some screws.
The bottom of described diamond positioning pin and circular alignment pin is provided with screw thread, and diamond positioning pin and circular alignment pin run through chuck body and be separately installed with clamp nut.
The direction of described diamond positioning pin and circular alignment pin and case of transmission class shaft parts bearing bore is consistent.
Compared with prior art, diamond positioning pin and circular alignment pin are arranged along horizontal line by the utility model, gripper shoe is symmetrically distributed in the both sides of diamond positioning pin and circular alignment pin line, compared with traditional diamond positioning pin is diagonally arranged with circular alignment pin, pin-and-hole position relationship is required to be reduced to one-dimensional coordinate requirement by two-dimensional coordinate, reduce manufacture difficulty and the debugging difficulty of fixture, the dowel hole position of the utility model part to be processed and clamp locating pin position be consistent namely can complete fixing, because part dowel hole location degree deviation, location was there is in order to prevent part locating hole and clamp locating pin, therefore one of them alignment pin is designed to rhombus.The utility model gripper shoe coordinates diamond positioning pin and circular alignment pin jointly to form the fixed space of fixture, by two clamp locating pin upper surfaces as support, eliminates the gripper shoe of traditional structure both sides.Clamp locating pin of the present utility model is convenient to processing, can greatly promote the crudy of case of transmission class part.
Further, the utility model gripper shoe is rectangle, for ensureing that gripper shoe and part to be processed have larger contact area, faced by the long limit therefore making gripper shoe and fixed space, clamps more firm like this.
Further, the bottom of the utility model diamond positioning pin and circular alignment pin is provided with screw thread, and diamond positioning pin and circular alignment pin run through chuck body and be separately installed with clamp nut, and when ensureing to unload part from fixture, alignment pin is not pulled out.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1,2, conventional brace forms fixed space by gripper shoe 3, due to the pitch-row of alignment pin, more far orientation is more accurate, therefore diamond positioning pin 2 and circular alignment pin 4 adopt the scheme of diagonally arranging, but this mode can make the position of fixture two alignment pins and part be difficult to centering, cause part and horizontal Machining centers main shaft can not at right angle setting, part adds and there is error man-hour, and after exceeding error range, part can not use.Simultaneously the diamond positioning pin 2 of conventional brace and circular alignment pin 4 are directly installed in chuck body 1, when unloading part from fixture, are easily extracted by pin, cause pore volume easy damaged in chuck body 1.
See Fig. 3,4, the utility model structurally comprises chuck body 1 and is arranged on the diamond positioning pin 2 in chuck body 1, circular alignment pin 4 and several gripper shoes 3; Diamond positioning pin 2 and circular alignment pin 4 are arranged along horizontal line, and gripper shoe 3 is symmetrically distributed in the both sides of diamond positioning pin 2 and circular alignment pin 4 line, diamond positioning pin 2 is provided with four gripper shoes 3 altogether with the both sides of circular alignment pin 4 line, and the line that two gripper shoes 3 of every side form is parallel with circular alignment pin 4 place line with diamond positioning pin 2, gripper shoe 3 is fixedly mounted in chuck body 1 by some screws.
See Fig. 5 (a), Fig. 5 (b), Fig. 6 (a) and Fig. 6 (b), diamond positioning pin 2 of the present utility model is provided with screw thread with the bottom of circular alignment pin 4, after diamond positioning pin 2 and circular alignment pin 4 run through chuck body 1, from bottom, clamp nut 5 is installed respectively.Gripper shoe 3 coordinates the fixed space of diamond positioning pin 2 and circular alignment pin 4 composition fixture jointly, and gripper shoe 3 of the present utility model is rectangle, and faced by the long limit of gripper shoe 3 and this fixed space.
When the utility model uses, diamond positioning pin 2 and circular alignment pin 4 are consistent with the axis direction of case of transmission class shaft parts bearing bore, and the dowel hole of part to be processed is corresponding with fixture diamond positioning pin 2 and circular alignment pin 4 position, part to be processed is positioned in gripper shoe 3, part to be processed dowel hole is coordinated with the utility model clamp locating pin, then uses platen clamp namely can complete fixing.The utility model gripper shoe 3 coordinates diamond positioning pin 2 and circular alignment pin 4 jointly to form the fixed space of fixture, by two clamp locating pin upper surfaces as support, eliminates the gripper shoe 3 of traditional structure both sides.Clamp locating pin of the present utility model is convenient to processing, can greatly promote the crudy of case of transmission class part.
