Abstract
The utility model discloses a tooling for assembling pin keys on a keyway with external threads, comprising a tooling platform, wherein the center of the tooling platform is provided with a positioning hole used for being inserted by a stud body with the keyway with external threads or a positioning truncated cone used for sheathing a threaded sleeve with the keyway with external threads; and the tooling platform is provided with a pin key assembly trough which surrounds the positioning hole or the positioning truncated cone, extends in axial direction and is used for being inserted by the pin keys. The tooling is simple in structure, economical and practical, can ensure the workers to quickly and stably assemble the pin keys in the keyways with studs or threaded sleeves at high assembly efficiency, and can well ensure the assembly requirements.
Description
Technical field
The utility model relates to a kind of frock that is used for assembling pin key on the external screw thread keyway, particularly a kind of frock that is used for installing pin key on the external screw thread keyway of stud or swivel nut.
Background technology
At present, develop rapidly along with aerospaceplane, connecting condition of work between the matrix of aerospaceplane engine requires more and more higher, common interference stud or swivel nut etc. can't reliably guarantee the job requirement of engine gradually, and band key stud or swivel nut are well positioned to meet the connection request between the engine matrix.
Band key stud or swivel nut more and more are used on the Aero-Space engine, and the keyway on band key stud or the swivel nut often is symmetrical arranged, and for reinforcing band key stud or the fastening effect of swivel nut, sets up pin key in the keyway of be everlasting stud body or swivel nut body.When at present using band key stud and pin key, normally earlier the stud body is screwed in the internal thread hole that connects matrix, then pin key is inserted in the keyway, pin key is with the interference that screw thread constitutes, and makes firm being fixed in the matrix internal thread hole of stud.
But the method efficiency of assembling of this hand assembled is lower, and because the keyway of band key stud or swivel nut all is to be symmetrical arranged 2 or 4 usually, therefore this existing method can't guarantee the symmetry of both sides pin key, pin key accurately can not be located, also there is very big problem in the quality conformance of assembled product.
Summary of the invention
The purpose of this utility model provides a kind of assembly tooling of Fast Installation pin key on the external screw thread keyway of band key stud or swivel nut.
The technical solution of the utility model is: the frock that is used for assembling pin key on the external screw thread keyway, comprise tooling platform, this tooling platform center is provided with the positioning round table that a locating hole or that is used for the stud body of plug-in mounting band external screw thread keyway is used for the swivel nut body of suit band external screw thread keyway, is provided with the axially extended pin key mounting groove that is used for the plug-in mounting pin key around described locating hole or positioning round table on the described tooling platform.
Described pin key mounting groove cross section is trapezoidal.
Described tooling platform is cylindrical tooling platform.
The frock that is used for assembling pin key on the external screw thread keyway that the utility model provides, in use, the key lever of pin key is inserted in the pin key mounting groove, the non-band key end of stud is inserted in the locating hole, then the keyway of stud body is cooperated with the guiding position of pin key and just put, touch stud, and then oppositely withdraw from, so just pin key and stud body are assembled together.
The frock that is used for assembling pin key on the external screw thread keyway that the utility model provides, in use, the pin key key lever is packed in the pin key mounting groove, the swivel nut body is sleeved on the positioning round table, then the keyway of swivel nut body is cooperated with the guide part of pin key and just put, touch the swivel nut body, so just pin key and swivel nut body are assembled together.
The utility model is used for the frock of assembling pin key on the external screw thread keyway, it is simple in structure, economical and practical, can guarantee in the keyway of pin key is packed into stud body or swivel nut body that the staff can fast and stable, the installation effectiveness height, and can well guarantee matching requirements, guarantee the symmetry of pin key effectively, solved the problem of assembled product quality conformance significantly.

The specific embodiment
Fig. 1, Fig. 2, Fig. 3 are the frock of the utility model embodiment 1 assembling pin key in the keyway of band key stud, this frock comprises cylindrical tooling platform 1, the center of this cylindrical tooling platform 1 is provided with a locating hole 2, is evenly equipped with two pin key mounting grooves 3 around locating hole 2 on the described cylindrical tooling platform 1.
Fig. 4, Fig. 5, Fig. 6 are the frock of the utility model embodiment 2 assembling pin key in the keyway of band key swivel nut, described frock comprises cylindrical tooling platform 4, the center of this cylindrical tooling platform 4 is provided with a setting circle platform 5, evenly is provided with two pin key mounting grooves 6 at interval around positioning round table 5 on the described cylindrical tooling platform 4.
Fig. 7, Fig. 8 are the structural representation of pin key, and pin key comprises trapezoidal key lever 7 and guide part 8.
In the utility model, the number of pin key mounting groove 3 is 2, and when specifically implementing, the number of pin key mounting groove 3 can change according to the keyway number on band key stud or the swivel nut.
In the utility model, pin key mounting groove 3 matches with the key lever 7 of pin key, and its cross section is trapezoidal.During concrete enforcement, the shape of cross section of pin key mounting groove is as the criterion with the key lever cooperation with realization, the alteration of form of the cross section of key lever, and the cross section of pin key mounting groove changes thereupon, but all should drop in the protection domain of the present utility model.
