Abstract
A locking combined fastening method is composed of a thread body (1), a reverse nut (2), a middle washer (3) and a nut (4), and is characterized in that after being pressed by a fastening piece, the threads of the reverse nut (2) and the nut (4) are opposite threads, so that the whole fastening piece cannot be loosened after the middle washer (3) is pressed. The method is convenient to operate and stable and reliable in work. The application range is wide, and all parts are not easy to damage. It has certain interchangeability, and is suitable for both civil use and military use.
Description
The present invention relates to a kind of locking fastening machines that mechanically compresses.
Existingly compress locking locking method, a kind of is to put plain washer on by casting die, put elastic washer again, then nut is compressed, this method is unclamped easily and was lost efficacy under vibration or alternate load effect, and another kind is radially to bore a hole on thread spindle, after nut compressed, a last cotter pin prevented that nut from withdrawing from; Because behind the nut clamping of workpieces, have with a certain distance from cotter pin, thereby it is loosening to cause that also nut compresses the back, also having a kind of is to open axial groove on thread spindle, after the seam packing ring is put into, compresses with nut again, with seam packing ring seam gland nut side, prevent to become flexible,, cause the thread damage of screw rod and nut after nut compresses easily because of this structure has been opened groove at thread spindle.
The invention provides a kind of Coombined locking and fastening method.
Realize that main technical schemes of the present invention is: an end has adjacent mutually opposite two screw threads on threaded body, the other end has the step of block material, when threaded body is put into fastened thing hole, nut is put to threaded body and is screwed, put into intermediate gasket then, putting into reverse nut again screws, seam on the intermediate gasket periphery is compressed to nut and rhetorical question nut respectively, the periphery of its multiform was compressed by the seam of intermediate gasket with the polygonal periphery of the rhetorical question nut that screws after nut screwed, making nut to ask in reply spins out, must make to nut also to same direction rotation, cause is reverse nut, then oppositely nut must advance to the inside, but because of the centre is screwed, so two nuts can not become flexible when the seam of intermediate gasket unclamps, the seam that compresses does not have the external force effect, and other acts on the power of being pressed on the thing and it can not unclamped.
Owing to adopted this method, after being compressed by casting die, under vibration or alternate load effect, can not unclamp, working stability is reliable, does not also influence fasteningly owing to changed to some extent by the casting die size, unclamps when refilling, screw thread is unaffected, accuracy of screw machining is less demanding, and operation, easy to process has certain interchangeability.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the erection drawing of Coombined locking and fastening method of the present invention.
Fig. 2 is the parts drawing of the intermediate gasket of Coombined locking and fastening method of the present invention.
Fig. 3 is Fig. 2 sectional view of Coombined locking and fastening method of the present invention.
Fig. 4 is the erection drawing of Coombined locking and fastening method of the present invention.
Fig. 5 is the erection drawing of Coombined locking and fastening method of the present invention.
Fig. 1, Fig. 2 and Fig. 3 are first embodiment, go up left end at threaded body (1) adjacent mutually opposite two screw threads are arranged, left end is dextrorotation, right-hand member is left-handed, threaded body (1) is put into the hole of wanting workpiece pressing, nut (4) put to threaded body (1) left end screw thread place screw, intermediate gasket (3) and reverse nut (2) are put into threaded body (1), screw reverse nut (2), two nuts of intermediate gasket (3) being aimed at the polygonal periphery compress, shown in Fig. 3 X, Y direction, can reach purpose of design.
Fig. 4 is second embodiment, before nut (4) is put into, has put into plain washer (6) and elastic washer (5), and this structure is more reliable.
Fig. 5 is the 3rd embodiment, and the fastening eccentric wheel of this method (or other part) is adopted at two ends on the axle, can reach fastening effect equally.
After first embodiment is finished, a cotter-pin hold is bored in threaded body (1) axial region radial position in reverse nut (2) back, load onto cotter pin then, whole fastening part is being had under the external load effect situation, will be better as its effect of fixing of the running gear of tank.
Whole fastening part except that intermediate gasket (3), except that can make metal, also can all make nonmetallic, or the part make nonmetallic.More than each technology all drop in the patented technology.
Claims (3)
1, a kind of Coombined locking and fastening method, form by nut, it is characterized in that, adjacent mutually opposite two sections screw threads are arranged on threaded body (1) one end, and when threaded body (1) is put into the hole of fastened thing, nut (4) is put to threaded body (1) and is gone up and screw, again intermediate gasket (3) is inserted in the threaded body (1), reverse nut (2) is spun on the threaded body (1), screws nut (2), the seam of intermediate gasket (3) is pressed in respectively on nut (4) and the reverse nut (2).
2, Coombined locking and fastening method according to claim 1 is characterized in that, threaded body (1) does not have an end of screw thread to be existing polyhedral bolt shape.
3, Coombined locking and fastening method according to claim 1 is characterized in that, intermediate gasket has the catch that can move distortion in (3).
