Description
Technical field
This utility model relates to screw locking machine technical field, particularly to a kind of snap lock screw structural.
Background technology
In industry manufactures, filature is a kind of at the equipment extensively used, it is possible to effective replacement manually carries out the taking, putting of screw, tightens.
But current screw tightening structure is all to be directly integrated in provide the electric screwdriver of power or gas to pull on, and the overall dimensions criticized by electric screwdriver, gas is limited, and at multiaxis application occasion, the spacing between screwdriver bit is generally big than the axle center distance that electric screwdriver gas is criticized.
Relating only to the degree of tightness of screw and the application scenario of screwed hole the most do not deviate from by screw, horizontal positioned formula multiaxis screw locking machine is not the most broken through.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of apply horizontally arranged, closely, multi-axial screw frequently locks and the snap lock screw structural unclamping (screwed hole do not deviate from by screw) occasion.
This utility model is achieved through the following technical solutions: a kind of snap lock screw structural, including including splined shaft, guiding spline, pneumatic screwdriver head installing ring, back-up ring, pneumatic screwdriver head, short bulb plunger, the first lock screw, the second lock screw and wire spring, the leading portion of described splined shaft is provided with external splines, external splines and the internal spline guiding spline form a pair spline pair, the back segment of splined shaft is provided with keyway and jump-ring slot, guiding spline and be axially provided with internal spline, before and after guiding spline, section is provided with screwed hole；
Being additionally provided with positioning step in guiding the leading portion screwed hole of spline, pneumatic screwdriver head installing ring is provided with screw countersunk head via around circumference, and the hindfoot portion of pneumatic screwdriver head installing ring is provided with positive stop lug boss, and the front section of described pneumatic screwdriver head installing ring is provided with pneumatic screwdriver head imitation-shaped groove；
The radial circumference position, stage casing of pneumatic screwdriver head installing ring is provided with screwed hole, and wire spring is arranged in the internal spline die cavity guiding spline.
As preferred technical scheme, described pneumatic screwdriver head inserts in pneumatic screwdriver head imitation-shaped groove, and short bulb plunger screws in the screwed hole radially of pneumatic screwdriver head installing ring stage casing, and pneumatic screwdriver head is fixed in pneumatic screwdriver head installing ring by short bulb plunger.
As preferred technical scheme, described back-up ring is installed on and guides the outboard end of spline and locked by the first lock screw.
As preferred technical scheme, described second lock screw is arranged at the fore-end of pneumatic screwdriver installing ring.
The beneficial effects of the utility model are: this utility model compact conformation is novel, adapt to product and screw the less workplace of location gap；This structure, independent of power set, can be installed on various occasion pneumatic, electric-powered, improve wildcard type；This structure is particularly well-suited to the occasion of power source horizontal positioned, by connecting with fixing, it is possible to well solves locking that screw is horizontally situated and unclamps.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the exploded view of this utility model embodiment a kind of snap lock screw structural；
Fig. 2 is the isometric sectional view of this utility model embodiment a kind of snap lock screw structural；
Fig. 3 is the partial sectional view of this utility model embodiment a kind of snap lock screw structural；

Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, in addition to mutually exclusive feature and/or step, all can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be by other equivalences or there is the alternative features of similar purpose replaced.I.e., unless specifically stated otherwise, an example during each feature is a series of equivalence or similar characteristics.
As Figure 1-Figure 4, a kind of snap lock screw structural of the present utility model, the leading portion of splined shaft 1 has external splines, external splines and the internal spline guiding spline 2 form a pair spline pair, axial displacement can be produced, back segment has keyway and jump-ring slot, keyway and jump-ring slot for loading on fixing on power set.
Guide that spline 2 is the most elongated has internal spline, front and back section has screwed hole, leading portion screwed hole is connected with pneumatic screwdriver head installing ring 3, back segment screwed hole connects for the first lock screw 7 and back-up ring 4, to limit the axial location of splined shaft, wherein leading portion is additionally provided with positioning step, it is ensured that pneumatic screwdriver head installing ring 3 and the axiality guiding spline 2.
Pneumatic screwdriver head installing ring 3 ring circumference has screw countersunk head via, can be connected with guiding spline 2 with the second lock screw 9 by it, pneumatic screwdriver head installing ring 3 back segment has positive stop lug boss, in order to limit the distance of elastic telescopic, pneumatic screwdriver head installing ring 3 leading portion has pneumatic screwdriver head imitation-shaped groove, and stage casing radial circumference has screwed hole, in pneumatic screwdriver head 5 inserts pneumatic screwdriver head imitation-shaped groove, short bulb plunger 6 screws in stage casing screwed hole radially, and after locking, pneumatic screwdriver head 5 is just securely seated between in pneumatic screwdriver head installing ring 3.
Wire spring 8 is arranged in the internal spline die cavity guiding spline 2, under the free release conditions of elastic force, wire spring 8 promotes splined shaft 1, the external splines back segment of splined shaft 1 contacts with back-up ring 4, now a whole set of structure is in elastic relaxation state, when pneumatic screwdriver head 5 is in working order by axial resistance, resistance is transmitted on wire spring 8, wire spring 8 is compressed, now splined shaft 1 and the spline pair guiding spline 2 formation produce axial displacement, make pneumatic screwdriver head 5 can automatically find the interior hexagonal groove of screw head accurately, screw locking, and be unlikely to suppress extremely in flight.
The beneficial effects of the utility model are: this utility model compact conformation is novel, adapt to product and screw the less workplace of location gap；This structure, independent of power set, can be installed on various occasion pneumatic, electric-powered, improve wildcard type；This structure is particularly well-suited to the occasion of power source horizontal positioned, by connecting with fixing, it is possible to well solves locking that screw is horizontally situated and unclamps.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
