Abstract
The utility model provides a notching and machining tool for Great Wall nuts, which includes an elastic positioning expanding sleeve, a lock nut and a threaded mandrel, wherein the elastic positioning expanding sleeve is a ring provided with a tapered inner wall longitudinal section and an opening; one end of the threaded mandrel is a smooth rod, the middle section of the threaded mandrel is a cylindrical body provided with external threads matched with the lock nut, and the other end of the threaded mandrel is a tapered body matched with the inner wall taper of the elastic positioning expanding sleeve; the diameter of the tapered body, near to the cylindrical body, is smaller than that of the tapered body, far from the cylindrical body. The notching and machining tool provided by the utility model has the benefits that through the adoption of the technical scheme, the low-efficiency machining method with great machining and clamping difficulty, high cost and low progress rate as a wire-electrode cutting is adopted conventionally is broken through, and has the advantages of simplicity and convenience for operation, accurate positioning, low machining cost, high efficiency and the like.
Description
Technical field
The utility model belongs to field of machining, especially relates to the fluting processing tool of a kind of Great Wall nut.
Background technology
The Great Wall nut is being widely used aspect the fields such as Aeronautics and Astronautics owing to possess good internal thread location and multiple locking effect.Its relevant criterion has well special requirement to the accurate positioning of Great Wall nut, quick and easy for installation, anti-loosening property.This just proposes very high requirement to the processing uniformity of a plurality of grooves of the end face of Great Wall nut position size, must be controlled within the very tight margin of tolerance.So the processing method of this end face multi-groove size is particularly important.Because the end face groove position of Great Wall nut is very many, and the parent wall of Great Wall nut is very thin, locate the improper nut body distortion that very easily causes, cause the internal thread of nut logical only defective.According to traditional wire-electrode cutting and processing method is very slow and the clamping difficulty is large, efficient is low, processing cost is high.
Summary of the invention
Problem to be solved in the utility model provides the fluting processing tool of a kind of Great Wall nut.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the fluting processing tool of a kind of Great Wall nut is characterized in that: comprise elasticity location ringfeder, locking nut and threaded mandrel;
Described elasticity location ringfeder is that the inwall longitudinal section is taper and the ring with an opening;
One end of described threaded mandrel is smooth shaft, interlude is to have the externally threaded cylinder that is complementary with described locking nut, the bullet that the other end is complementary for the inwall taper with described elasticity location ringfeder, the diameter at the close described cylinder place of described bullet is less than the diameter away from described cylinder place.
Described elastic spacing ringfeder is that elastomeric material is made.
Described elastomeric material is rubber.
The outer dia of described elasticity location ringfeder and the inner diameter that described Great Wall to be processed nut has internal thread match.
Advantage and the good effect that the utlity model has are: owing to adopt this technical scheme, broken and adopted line cutting processing and the clamping difficulty is large, cost is high, progress is slow inefficient processing method under the regular situation, had simple and easy to operate, accurate positioning, processing cost low, efficient advantages of higher.

The specific embodiment
As shown in Figure 1, the utility model provides the fluting processing tool of a kind of Great Wall nut, comprises elasticity location ringfeder 2, locking nut 3 and threaded mandrel 4; Elasticity location ringfeder 3 is taper 9 and the ring (as shown in Figure 2) with an opening 8 for the inwall longitudinal section; One end of threaded mandrel 3 is smooth shaft 5, interlude is the cylinder with the external screw thread 6 that is complementary with locking nut 3, the bullet 7 that the other end is complementary for the inwall taper 9 with elasticity location ringfeder 3, the diameter at bullet 7 close cylinder places is less than the diameter (as shown in Figure 3) away from the cylinder place.
The outer dia of elasticity location ringfeder 3 and the inner diameter that Great Wall to be processed nut 1 has internal thread match.
The course of work of this example: the end with smooth shaft 5 of threaded mandrel 4 is packed in the ringfeder 2 of elasticity location from the top down, elasticity location ringfeder 2 is packed on the bullet 7 on the threaded mandrel 4; Locking nut 3 is screwed on the external screw thread 6 on the threaded mandrel 4, makes it to be in loosening state; Nut 1 female the inner in Great Wall is placed on the ringfeder 2 of elasticity location down; Tighten locking nut 3, this moment, whole threaded mandrel 4 moved down with respect to elasticity location ringfeder 2, bullet 7 on the threaded mandrel 4 makes elasticity location ringfeder 2 outside tensioners to extrapolation elasticity location ringfeder 2, and elasticity location ringfeder 2 utilizes frictional force and Great Wall nut 1 chucking.
Next be installed in the above-mentioned assembly that assembles in the scroll chuck that dividing head is housed on the horizontal milling machine and clamp the smooth shaft 5 of threaded mandrel 4; Can utilize the principle of dividing head calibration to carry out the fluting processing of a plurality of grooves position.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
