The utility model discloses a drilling and milling fixture for a wiring terminal of an isolating switch, which comprises a fixture body (1) and a revolved body (2). A drill sleeve (3) is inlaid on the pipe wall of the revolved body (2), and a circular hole is arranged in the middle of the revolved body (2); the revolved body (2) is sheathed in the fixture body (1) in a penetrating manner and can freely rotate in the fixture body (1); the right end of the revolved body (2) is connected with an index plate (4) at the outer side of the fixture body (1); circular holes at different angles are arranged on the index plate (4), and a circular hole corresponding to the index plate (4) is arranged on the fixture body (1); a retainer ring (7) is fastened at the outer side of the index plate (4) on the revolved body (2), so that the revolved body (2) cannot axially move; an end cover (9) is fixed at the outer part of the right end of the revolved body (2), and a thread arranged in the end cover (9) can be matched with a bolt (14) at the left end of the revolved body (2). The drilling and milling fixture can conveniently carry out drilling, milling and assembling and has the characteristics of high drilling and milling speed, low labor intensity and high working efficiency.
Description
Technical field
The utility model relates to a kind of brill and mills clamp for machining, particularly a kind of brill hole milling clamp for machining of isolating switch binding post.
Background technology
Binding post is the key components and parts of the above outdoor high-voltage isolating switch of 126KV, and it is bearing the conveying of rated current, bears corresponding dynamic and thermal stability electric current in case of necessity.Binding post is that riveted joint has terminal plate in the copper pipe end, holes on the tube wall of copper pipe then, because the out-of-shape of binding post, existing drilling machine or milling machine table pincers are not easy to be installed, and cause the processing dimension error big easily.
Summary of the invention
To be that design is a kind of be installed conveniently, can bore fast the isolating switch binding post that mills and bore and mill clamp for machining the purpose of this utility model.
The technical solution of the utility model is: a kind of isolating switch binding post drilling-milling clamper is characterized in that jig main body comprises clamp body and revolving body, the tube wall of revolving body studs with drill bushing, the centre of revolving body is a circular hole, and revolving body is set in the clamp body, can freely rotate in clamp body; The revolving body right-hand member is connected with the one division dish in the clamp body outside, and index dial is provided with the circular hole of different angles, and the circular hole corresponding with index dial arranged on the clamp body, and the calibration bearing pin can make index dial and clamp body connect together, and also is provided with turning handle on the index dial; Be fastened with a back-up ring in the index dial outside on the revolving body, revolving body can not be moved axially; The external stability of revolving body right-hand member has end cap, is provided with screw thread in the end cap, can match with the bolt of revolving body left end.
During use, the bolt of revolving body left end is connected on the end cap, binding post is stuck on the bolt with split washer after passing circular hole in the middle of the revolving body, by bolt binding post is fastened on the revolving body.The clamp body of drilling-milling clamper is fixed on the workbench of milling machine or drilling machine, turning handle when forwarding revolving body to need processing hole, connects together index dial and clamp body with the calibration bearing pin, can finish the hole processing of pair of wire connection terminals, unclamp bolt and remove split washer and can take out workpiece.
The binding post drilling-milling clamper that the utility model provides bores to mill to process and is installed conveniently, and labour intensity is low, high efficiency.
