Abstract
The utility model discloses a device for assembling a self-locking nut, comprising a female die [1] and a male die [2], wherein the male die [2] is connected with the female die [1] and is made of tool steel; an interface of the male die [2] is matched with the overall dimension of the bottom end of a part; the female die [1] is made of tool steel; and an interface of the female die [1] is matched with the overall dimension of the top end of the part and the size of the closed part of the part. The device is simple and convenient for processing and use, and solves the problems that the processing period is long, the batch requirement cannot be met and the precision is difficult to ensure, so that the cost for processing parts is reduced and the time and labor are saved; and compared with the traditional processing method, the efficiency is improved by over five times.
Description
Technical field
The utility model relates to a kind of self-locking nut assembling device, is used to solve lathe turning processing self-locking nut part closing in problem, especially at batch producing part, quantity is many and precision is high finding processing.
Background technology
The self-locking nut part is assemblied by nut and back-up ring, its processing and assembly technology flow process are earlier with basic external form and the endoporus of product with the mode processing parts of turning, again with the processing mode system hexagonal profile of part with milling, the back-up ring of packing into, the mouth and the assurance of making nut at last compress back-up ring, just key component.For a long time, engine lathe be by one be installed on roller press fit on the knife rest self-locking nut opening edge of back-up ring along making it form a fillet, thereby finish the closing in of self-locking nut.But such method, because the roller position limits, the clamping difficulty, turning processing vibration is big, and every the extruding can only finish 1/4th circles and close up, and nut part of promptly every processing must rotary main shaft (being part) 4 times, takes time and effort.This part belongs to batch and to produce part, and production efficiency low directly influenced finishing of manufacturing schedule.In addition, do not find better processing method.
The utility model content
Deficiencies such as the prior art working (machining) efficiency is low in order to solve, precision can't guarantee, technical problem to be solved in the utility model is to provide a kind of self-locking nut assembling device to increase work efficiency and machining accuracy.The utility model adopt punch to be connected scheme that disposable extruding locatees with die, eliminate every the extruding and can only finish 1/4th circle closing ins, be nut part of every processing must rotary main shaft (being part) 4 times phenomenon, improve the quality of products, guarantee die quality, improve demoulding efficiency.
In order to solve the problems of the technologies described above, the self-locking nut assembling device that the utility model provides, comprise die and punch, punch is connected with die, wherein: punch adopts tool steel to make, its interface matches with the overall dimensions of part bottom, the part bottom is put into calculated good bore in advance, is easy to take out this part after machining; Die also adopts tool steel to make, and its interface matches with the overall dimensions on part top and the size at part closing in position, the part that processes is put into calculated good bore in advance.
Preferably, in the above-mentioned self-locking nut assembling device of the utility model, also comprise be used to step up between punch and die bench vice, play and once push the mouth that positioning action is finished self-locking nut.
With respect to prior art, the utility model frock is made up of punch and die two parts, all adopts tool steel to make, and hardness can reach 55-60.Its process principle as shown in Figure 4.Adopt new frock processing self-locking nut crimping part, not only can guarantee the final length overall size that requires of drawing fully, and production efficiency obtained improving greatly, than processing method before, efficient improves more than 5 times.Even long-term the use, deviation appears in the frock size, only needs the interlock end face of grinding die to correct, and is convenient and strength-saving.
Description of drawings
Fig. 1 is a self-locking nut component assembling schematic diagram.
Fig. 2 is the structural representation of the utility model self-locking nut assembly tooling.
Fig. 3 is the location diagram of die, part, punch in the assembly tooling of the utility model self-locking nut.
Fig. 4 is assembly tooling of the utility model self-locking nut and aid assembly work schematic diagram.
Fig. 5 is that self-locking nut uses frock extruding back-up ring to finish the schematic diagram of mouth.
Wherein: 1 is die; 2 is punch.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further set forth the utility model.These embodiment be interpreted as only being used to the utility model is described and be not used in the restriction protection domain of the present utility model.After the content of having read the utility model record, those skilled in the art can make various changes or modifications the utility model, and these equivalences change and modification falls into the utility model claim institute restricted portion equally.
As shown in Figure 1, the self-locking nut assembly comprises self-locking nut and back-up ring, and the self-locking nut assembly is exactly the part that the utility model frock will be processed, and the back-up ring that processes is packed in the self-locking nut.
As shown in Figure 2, the self-locking nut assembly tooling that the utility model preferred embodiment provides comprises die 1 and punch 2, punch 2 is connected with die 1, punch 2 adopts tool steel to make, its interface matches with the overall dimensions of part bottom, the good bore of calculating is in advance put in the part bottom, after machining, be easy to take out this part; Die 1 also adopts tool steel to make, and its interface matches with the overall dimensions on part top and the size at part closing in position, the part that processes is put into calculated good bore in advance.
In the present embodiment, the occlusal surface of die 1 the extruding trace can occur easily in the process of long-time extruding, and deviation appears in the frock size, only needs the interlock end face of grinding die 1 to correct, and is convenient and strength-saving.
As shown in Figure 3, with diagramatic way assembling, the design size between mould and the fit dimension of part are finished by accurate Calculation with punch 2, part and die 1, have accomplished not only to install convenient but also convenient disassembly.
As shown in Figure 4, in the self-locking nut assembling device that another preferred embodiment of the utility model provides, also comprise be used to step up 1 of punch 2 and die bench vice, play and once push the mouth that positioning action is finished self-locking nut.
Be that self-locking nut needs following frock extruding back-up ring to finish the schematic diagram of mouth as shown in Figure 5; After finishing the assembling of back-up ring, its mouth is processed, guaranteed the final length overall size that requires of drawing.
In sum, because the utility model self-locking nut assembling device all adopts tool steel to make, the phenomenon that its toughness of material is better, intensity is higher, wearability is higher, ingenious, accurate design size has guaranteed product and the mould friction is impaired has improved demoulding efficiency.The utility model has used the scheme of disposable extruding location, has improved product quality, and production efficiency has also obtained large increase simultaneously, has satisfied batch product demand fully.
