Abstract
The utility model relates to a machining device for sub-reflector parts. The technical problem to be resolved is to provide a holding device for the flexible machining of sub-reflector parts, which can increase repetitive positioning precision and reduce clamping frequency. The holding device is characterized in that the holding device mainly comprises a 3R flexible clamp and a dedicated tooling capable of being connected with the 3R flexible clamp and a part blank. The structure of the holding device is reasonable, the applicability of a machine tool is high, the repetitive positioning precision can reach the grade of umm, and the holding device resolves the problem on how to machine parts requiring multiple processes, repetitive clamping and high symmetry degree and concentricity, and increases the machining quality and machining efficiency.
Description
Technical field:
The utility model relates to the processing unit (plant) of secondary reflectors part.
Background technology:
The secondary reflectors part belongs to and uses the typical thin-walled elongated part of cathode copper as material, irregular structure, and part inwall fineness requires highly, is absolute inclination angle between the inwall.This structure is brought a following difficult problem to processing:
1. because copper material is softer, clamping is yielding.
2 thin-walled parts are as easy as rolling off a log in process to be subjected to the cutting force effect and to be out of shape.
3. irregular shape is difficult to find suitable clamping face.
4. the absolute inclination angle of inwall and inner bottom surface adopts conventional groove milling processing method to be difficult to reach.
In the prior art, the common processing core rod that adopts---process of mashed core---is processed---in electroforming after the casting, solve numerous manufacturing deficiencies of thin-walled parts, but because the processing of part core rod needs multiple clamping, resetting; If still adopt traditional vice installation way, clamping is time-consuming bothersome, and efficient is low, and the people is that the error that causes is many, is difficult to reach high-precision processing request.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of clamping device that is used for the flexible processing of secondary reflectors part, can improve repetitive positioning accuracy, reduces clamping times.
For realizing above purpose, the utility model is achieved through the following technical solutions:
A kind of clamping device that is used for the flexible processing of secondary reflectors part is characterized in that: it mainly is made up of with the special tooling that is used for being connected 3R flexible fixture and part blank the 3R flexible fixture;
The inner cavity size of special tooling 4 is consistent with the technology piece size of part blank to be processed, and its both cooperation is loose fit, by directions X location and the clamping of trip bolt 3 with part, by Y direction location and the clamping of trip bolt 2 with part.
The benchmark navigation system that described 3R flexible fixture is whole clamping device, it mainly comprises reference base 7, reference element 6, pull bar 13, four trip bolts 5; Pull bar is connected reference base and locks with reference element 6; By four trip bolts 5 reference element 6 is linked to each other with special tooling 4 again and makes frock concentric with the 3R anchor clamps, guarantee X, Y to the location overlap fully with the center of 3R flexible fixture.
The utility model brings following beneficial effect:
Its structure rationally, the lathe applicability is strong, can make repetitive positioning accuracy can reach the umm level, has solved a processing difficult problem that needs multiple working procedures, multiple clamping, symmetry, part that concentricity requirement is high, has improved crudy and working (machining) efficiency.
Description of drawings:
Fig. 1: structural representation of the present utility model
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Referring to Fig. 1, present embodiment is the work holder that a kind of CNC milling machine uses, five fine finishining that are specifically designed to five processing of the plating core rod of secondary reflectors part when blank and electroplate the back part.Among the figure, 1 is part blank to be processed; 2 is trip bolt; 3 is trip bolt; 4 is special tooling; 5 is trip bolt; 6 is reference element; 7 is reference base; 8,9,11 is bridge screw; 10 are long pressing plate; 12 is cushion block; 13 is pull bar; 14 is process tool.
Reference base 7 positions by 4 resilient reeds with reference element 6 in the 3R flexible fixture, and undertaken fastening by pull bar 13, its accessible repetitive positioning accuracy is 0.003mm, the blank processing of secondary reflectors part and plating back finishing requirements symmetry 0.03mm use this device can reach the symmetry requirement fully.
The secondary reflectors part requires a clamping, and five of moulding must be used five processing, and cushion block 12 fills up on the lathe table top, and long pressing plate 10 of reference base 7 usefulness and bridge screw 8,9,11 are pressed on the cushion block, guarantee that machine tool bumps when rotated less than table top.
Part blank to be processed is loaded on the special tooling 4, special tooling is fastening by four trip bolts 5 and 3R anchor clamps, it is concentric with the 3R anchor clamps to reach special tooling, guarantee X, Y to the location overlap fully with the center of 3R flexible fixture, the inner cavity size of special tooling is consistent with part process piece size, but cooperating is loose fit, by directions X location and the clamping of trip bolt 3 with part, by Y direction location and the clamping of trip bolt 2 with part, each blank to be processed is installed on the special tooling, processes.
