Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly the efficient device for repairing of widely used accurate securing member self-locking nut in a kind of aerospace field.
Background technology
In modern military equipment, in order to ensure equipment reliability of operation, require to accomplish zero-fault to each link.The general principle of self-locking nut is exactly apply certain external force in default closing in place of nut to allow it produce certain deformation, reaches the locking torque requirement of expection, reaches locking object after locking by the architectural characteristic of self-locking nut self and mechanical characteristic, can not loosen.
The self-locking torque of self-locking nut requires very strict, not only requires that it will reach more than the value of certain regulation, also wants to exceed certain codomain.Therefore, experimental test must be carried out by standard regulation after completion produced by self-locking nut and whether reach requirement to check its locking torque.In the process of self-locking nut, the thickness etc. of closing in parameter, thermal treatment quality, face coat quality, screw processing quality, closing in place matrix is the key factor affecting self-locking nut test data.The thickness of screw processing quality and closing in place matrix can be cured by process program and process equipment; The nuance of thermal treatment quality and face coat quality often impacts the locking torque of self-locking nut, for avoiding causing product rejection, needs the closing in parameter being obtained each batch products by several times test.In prior art, each part part can only once close up test, defective, scraps, causes larger economic loss to company, in order to cost-saving, devise the efficient device for repairing of a kind of self-locking nut.
Utility model content
For solving the problems of the technologies described above, the utility model provides the efficient device for repairing of a kind of self-locking nut, thus reaches and reprocess the cost-saving effect of part.
The utility model is achieved by following technical solution:
The efficient device for repairing of a kind of self-locking nut, this device for repairing comprises standing part, vertical slot, groove one, groove two, groove three, working portion, taper shank head, handle; Described standing part is hollow-core construction, is arranged on whole device foremost, can be fixed on lathe, be structure as a whole with working portion; Described vertical slot runs through standing part tail end, is arranged on working portion front position; Described working portion outer end is provided with the external screw thread coordinating self-locking nut work, forms expansion set; Self-locking nut inwall is provided with the internal thread of cooperating portion outboard work; Described groove one, groove two, groove three are successively set on the inner relevant position of working portion, prolong working portion axially in step-like structure; Described taper shank head conically structure, links into an integrated entity with handle; Described taper shank head connection handle is front end; The cylindrical structure of handle, is arranged on the caudal end of whole device.
Described vertical slot and groove one, groove two, groove three are mutually vertical, formation ' ten ' character form structure.
The efficient device for repairing of the utility model self-locking nut, adopts the structure of fluting, inwardly can shrink, reprocess when nut screws in and do not stopped during the expansion set work that working portion is formed.Structure is simple, and be easy to processing, cost is low, and can reach the object that self-locking nut reprocesses again can be cost-saving to company.
Accompanying drawing explanation
Fig. 1 is the efficient device for repairing structural representation of the utility model self-locking nut.
Fig. 2 is the self-locking nut structural representation needing in the utility model to reprocess.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The efficient device for repairing of a kind of self-locking nut as shown in Figure 1, mainly comprises standing part 1, vertical slot 2, groove 1, groove 24, groove 35, working portion 6, taper shank head 7, handle 8.Standing part 1, in hollow-core construction, is arranged on whole device foremost, is fixed on lathe, be integrated with working portion 6.Vertical slot 2 runs through standing part 1 tail end, is arranged on working portion 6 front position.Working portion 6 outer end is provided with the external screw thread coordinating self-locking nut work, forms expansion set; Self-locking nut inwall is provided with the internal thread worked outside cooperating part 6.Groove 1, groove 24, groove 35 are successively set on the inner relevant position of working portion 6, prolong working portion 6 axially in step-like distribution.Taper shank head 7 conically structure, links into an integrated entity with handle 8.Taper shank head 7 connection handle is 8 front ends; The cylindrical structure of handle 8, is arranged on the caudal end of whole device.Described vertical slot 2 and groove 1, groove 24, groove 35 are mutually vertical, formation ' ten ' character form structure.The expansion set that described working portion 6 is formed adopts elastomeric material to make.Taper shank head 7, taper shank 8 adopt material working tool steel to make.
During work: first the fixed part of device for repairing is fixed on lathe, again self-locking nut to be reprocessed is screwed on the external screw thread of working portion 6, handle 8 is promoted taper shank head 7 to be axially slowly pressed into along working portion 6, along with the press-in of taper shank head 7, the expansion set that working portion 6 is formed radially opens, and self-locking nut crimping deformed area can be repaired.Reparation amount in self-locking nut crimping deformed area regulates by tapering.
The efficient device for repairing of the utility model self-locking nut has the following advantages:
1, the efficient device for repairing of a kind of self-locking nut described in the utility model, expansion set adopts has flexible materials processing, and taper shank adopts tool steel material processing, and material purchases are convenient, can reuse and have longer service life;
2, structure is simple, and be easy to processing, cost is low, and can reach the object that self-locking nut reprocesses again can be cost-saving to company;
3, use simple to operate easy to learn;
4, both can use on engine lathe, can use on punch press again.
