The utility model solves the problems of the current technology for machining parts with inner arc that the machining cost is high, the clamping is difficult, cutter feeding is slow, the machining cycle is long, the production efficiency is low and batch production is difficult to realize. The clamp is provided with a central stepped hole and a threaded hole which is used for being matched with the connecting bolt of a lathe, the small-diameter end of the central stepped hole is used for being matched with a lathe main shaft, the ledge end surface of the central stepped hole is a first limiting surface, a second limiting surface is machine on the hole wall at the large-diameter end of the central stepped hole, positioning holes are formed on the outer circumference surface of the fixture, and screws are arranged and are packaged in the positioning holes by a gland, the inner end of a screw rod is connected with a connecting hole of the part with inner arc in a threaded way, the end plane of the part with inner arc is clung to the second limiting surface, and one side plane of the part with inner arc is clung to the first limiting surface. The special fixture is used in machining of parts with inner arc.

Description

A kind of special fixture of processing inner arc class part
Technical field
The utility model relates to a kind of anchor clamps of processing inner arc class part, belongs to the Machining Technology field.
Background technology
During to inner arc class part processing (inner arc class part is referring to Fig. 1 and Fig. 2), the conventional inner arc boring or the processing methods of numerical control milling of adopting more.Need could realize on CNC milling machine during the milling inner arc that boring will be processed with boring machine.Two kinds of process technology processing charges height and clamping difficulty, feed is slow, and the process-cycle is long, and production efficiency is low, is unfavorable for producing in batches processing.
The utility model content
The purpose of the utility model is in order to solve the problem that the processing charges that existing inner arc class part processing technology exists is high, clamping is difficult, feed is slow, the process-cycle is long, production efficiency is low and be unfavorable for producing in batches, and then a kind of special fixture of processing inner arc class part is provided.
The technical scheme of the utility model is: a kind of special fixture of processing inner arc class part comprises clamp body, six glands and six screw rods; Have central stepped on the said clamp body, the smaller diameter end of central stepped is used for cooperating with Lathe Spindle Box, also has a plurality of screwed holes on the clamp body; Be used for matching with the lathe connecting bolt; The shoulder end face of central stepped is first confined planes, is processed with six second confined planes on the larger diameter end hole wall of central stepped, is evenly equipped with six locating holes on the outer circumference surface of said clamp body; Each locating hole is corresponding with corresponding second confined planes; Be provided with a screw rod in each locating hole, the outer end of each screw rod is encapsulated in the locating hole of clamp body through a gland, and the inner of each screw rod is threaded with the connecting hole of an inner arc class part; The transverse plane and second confined planes of inner arc class part are adjacent to, and the side plane and first confined planes of inner arc class part are adjacent to.
The utility model compared with prior art has following effect: adopt the utility model to carry out the processing of inner arc class accessory turning, not only having overcome needs the technical barrier with dedicated numerical control equipment, has also satisfied the requirement that parts batch is produced simultaneously.That the utility model also has is simple in structure, clamping is simple, feed is fast, the process-cycle is short and advantage of high production efficiency, is convenient to be generalized in the inner arc turning technology of field of machining inner arc class part.
Description of drawings
