Abstract
The utility model relates to a thread connecting piece in a movable connection structure. The thread connecting piece comprises a head and a screwed tail, wherein a side channel which is embedded with a screw driver is formed in the head; the screwed tail is a threaded sleeve with a spiral body structure; and the head is welded with an initial ring of the threaded sleeve to form a whole. According to the thread connecting piece, a spring steel material is used, threads are manufactured by adopting a spring manufacturing process, and interference fit is adopted, so that the thread connecting piece has a relatively large amount of elastic deformation and easily implements pre-tightening; and under the action of an alternating load, the elastic force can offset the action of an alternating fretting load, and a looseness preventing function is realized.
Description
Technical field
The utility model relates to the threaded connector in the moving connecting structure.
Background technique
Purposes: moving connecting structure is because there is relative movement, screw often becomes flexible and causes structural failure, threaded connector need to have certain anti-loose ability, can repeatedly dismantle the service behaviour (these two requirements often are difficult to satisfy simultaneously) that does not affect precision in this occasion, and claimed structure is simple simultaneously, technology capability good.
With the immediate prior art of the utility model:
Existing Cock screw production technology is first punching press, the reprocessing screw thread.Good economy performance when producing in enormous quantities, but locking problem do not solved.The locking thread mode of three quasi-traditions and that locking, locking, the riveting of machinery of rubbing is rushed is locking, admittedly detain locking.Main dependence third party power is advanced locking, the actual frictional force that refers to, and the quality of its anti-loosing effect depends on the size of third party's power.But the frictional force that increases has limitation, increases and has lacked, and anti-loosing effect is poor, how has increased, and is difficult to dismounting; Wherein destructive locking mode does not allow repeatedly to dismantle.Structure is locking to be newer locking mode, and such as Tang Shi locking thread mode, the Tang Shi screw thread has left-handed and characteristics right-handed thread simultaneously.Use the nut of two kinds of different rotation directions during connection: the nut on the work supporting surface is called tightening nut; Nut on the non-bearing surface is called locking nut.During use first with the tightening nut pretension, again with the locking nut pretension.In the situation that vibrate, impact, the trend that tightening nut can become flexible, because the pine of tightening nut moves back the tightening direction that direction is locking nut, tightening of locking nut exactly stoped the pine of tightening nut to move back, and causes tightening nut to become flexible.The structure anti-loose structure is complicated, and Economy is relatively poor, can't use at the such miniature parts of Cock screw.
The deficiencies in the prior art: a. can't pretension; B. locking poor for alternation fine motion load
The model utility content
This model utility is mainly used in the small-sized Cock screw that is under the fretting wear state, and the problem that mainly solves is that this threaded connector is easy to pretension, and can repeatedly dismantle does not affect precision, and anti-loosening property is good.
A kind of threaded connector comprises head and screws afterbody that described head is provided with the side channel chimeric with bottle opener, and the described afterbody that screws is leptospira structure, and described head and the initial lap welding of described leptospira structure are connected into integral body.
The described afterbody that screws is around forming by the spring steel steel wire coil.
The cross section of described spring steel steel wire is triangle.
Because this threaded connector uses spring steel material, adopt spring manufacturing process screw thread, adopt interference fit, larger elastic deformation amount is arranged, pretension easy to implement; Under the alternate load effect, this elastic force can be offset alternation fine motion load, plays locking effect.Embed the installation that the rotation of two side channels realizes screw or bolt or double-screw bolt with the flat head screw-driver.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein, 1, head; 2, screw afterbody; 3, side channel.
Embodiment
As shown in Figure 1, a kind of threaded connector comprises head 1 and screws afterbody 2 that described head 1 is provided with the side channel 3 chimeric with bottle opener, and the described afterbody 2 that screws is leptospira structure, and described head 1 is connected into integral body with the initial lap welding of described leptospira structure.
Use stamping die to make the steel wire of triangular-section, suitably adjust the production v thread with the technique of computer spring making machine (spring coiling machine) processed springs, thread size is than standard thread large about 2%; Processing flat head or interior six square bolt heads and initial lap welding are connected into integral body.
Before heating, the starting point of 2 ends is tied up with iron wire; With size suitable hollow steel pipe or profiling axle,, guarantee straightness accuracy spring housing in the above.
This part has possessed the advantage of spring and screw thread, can provide certain pretightening force to Cock screw when screwing screw thread, and because compare with general cutted thread, the rigidity of part is little, can produce larger elastic deformation amount under certain pretightening force.
The material of triangular-section can get by punching press or hydraulic pressure installation preparation, and the material rotational stabilization of triangular-section is also relatively good.
The impact of adopting suitable technological measure to eliminate the distortion of spot welding double thread is the key that the utility model can be successful.Part among the figure is the in-line screw, and in fact the threaded connector of hexagon head, interior hexagonal structure such as bolt, double-screw bolt also can adopt this production technology.
Claims (3)
