Description
Technical field
The utility model relates to a kind of sawtooth stop swivel nut that prevents that swivel nut rotates in the matrix screw, belongs to the technical field that is threaded.
Background technique
At present, in the prior art in order to strengthen the intensity of low-intensity engineering material matrix tapped hole, general all the employing installed a swivel nut mode that has internal and external threads that adopts high-strength material to make additional in the tapped hole of low-intensity engineering material matrix, though adopt this mode can strengthen the tapped hole intensity of low-intensity engineering material matrix effectively, but because when adopting this mode, require swivel nut must be connected to an integral body with the tapped hole of matrix, can not become flexible, therefore requiring the outside thread of swivel nut must be the interference fit screw thread with the internal thread of the matrix that is cooperated, and the required precision of processing interference fit screw thread is high, its difficulty of processing is very big, often adopt the way of apolegamy, this not only causes the processing cost height, but also causes assembling difficulty, and if when assembling, control the bad softer matrix tapped hole of material that also can damage; And if swivel nut adopts conventional screw thread to be connected with the matrix screw; then in use, when bolt was screwed into or back-outs swivel nut, swivel nut was easy to rotate in the tapped hole of matrix; this has not only caused the trouble of using, but also has lost the purpose to the protection of matrix tapped hole.Therefore, that swivel nut is installed in the tapped hole of matrix is not ideal in the mode that strengthens low-intensity engineering material matrix tapped hole intensity for existing these.
The model utility content
The purpose of this utility model is: provide a kind of that do not need to make the interference fit screw thread and be connected reliably, be difficult for loosening, processing with matrix and install all to be easy to sawtooth stop swivel nut, to overcome the deficiencies in the prior art.
The utility model is achieved in that sawtooth stop swivel nut of the present utility model comprises the swivel nut that is provided with outside thread and interior threaded hole, this sawtooth stop swivel nut is made up of swivel nut and sawtooth stop ring, on the external cylindrical surface of swivel nut one end, be provided with stop tooth, on the external cylindrical surface of sawtooth stop ring, be provided with external tooth, on the endoporus of sawtooth stop ring, be provided with internal tooth, and the sawtooth stop ring can be enclosed within on the stop tooth of swivel nut, and the internal tooth of sawtooth stop ring can mesh with the stop tooth of swivel nut.
On above-mentioned swivel nut, be provided with two symmetries be used to push make swivel nut can close up the distortion the circular arc straight trough.
The material of above-mentioned swivel nut and sawtooth stop ring is the 40CrNiMoA hardening high-strength steel.
Owing to adopted technique scheme, after in the tapped hole that swivel nut of the present utility model is screwed into matrix, the mode of the sawtooth stop ring that will have an interior external tooth by extruding embeds the external tooth of this sawtooth stop ring in the big hole wall of the step type blind hole of matrix into, make the interlocking of sawtooth stop ring and matrix be one, and the internal tooth of sawtooth stop ring and the stop tooth of swivel nut are meshed, can prevent that like this transmission takes place swivel nut when bolt being screwed into or back-outing swivel nut in matrix.Therefore swivel nut outside thread of the present utility model does not need to be connected to interference fit with the internal thread of matrix and is threaded, only need the outside thread of swivel nut is processed as traditional regular screw threads, swivel nut and matrix can be connected as a single entity reliably, so not only can reduce requirement greatly to swivel nut outside thread machining accuracy, but also the unfailing performance that has improved installation efficiency and be threaded.So the utility model is compared with prior art, the utility model not only have with matrix be connected reliably, advantage that swivel nut can not rotate, but also have easy processing, easy to assembly and can effectively protect advantages such as matrix tapped hole.The utility model is particularly suitable for that each field such as Aeronautics and Astronautics is locking as important connection, the fastening piece of anti-rotation uses.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as the foundation of the utility model being done any restriction.
Embodiment of the present utility model: sawtooth stop swivel nut of the present utility model is formed (as Fig. 2, Fig. 3 and shown in Figure 4) by swivel nut 1 and sawtooth stop ring 2, on the external cylindrical surface of swivel nut 1 one ends, produce stop tooth 1-1, on the external cylindrical surface of sawtooth stop ring 2, produce external tooth 2-1, in the endoporus of sawtooth stop ring 2, produce internal tooth 2-2, sawtooth stop ring 2 can be enclosed within on the stop tooth 1-1 of swivel nut 1, and the internal tooth 2-2 of sawtooth stop ring 2 can be meshed with the stop tooth 1-1 of swivel nut 1; In order to make swivel nut have auto-lock function, (the circular arc straight trough 1-2 of two symmetries of making makes the internal thread of swivel nut can produce slight distortion to make the circular arc straight trough 1-2 that swivel nut can be closed up be out of shape that is used to push of two symmetries on swivel nut 1, reach the purpose of self-locking, owing to inside and outside the swivel nut screw thread is arranged all, when extruding is closed up, the location was relatively more difficult when a circular arc straight trough closed up, the screw thread of damaging easily, so adopt the circular arc straight trough of two symmetries, just very convenient during closing in, and the closing in frock is simple and easy to processing), adopt the fashion of extrusion of transmission swivel nut 1 extrusion-deformation to be become the sub-elliptical shape simultaneously by circular arc straight trough 1-2, when bolt 4 was screwed into swivel nut 1,1 pair of bolt 4 of swivel nut had the self-lock force of a pretension like this; The tapped hole of matrix 3 is made into the blind hole of step type; and in the aperture of the blind hole of this step type, produce the internal thread that matches with the outside thread of swivel nut 1; then swivel nut 1 is screwed in the tapped hole of matrix 3; make the stop tooth 1-1 end face of swivel nut 1 mutually concordant with the end face of matrix 3; then with the stop tooth 1-1 of the internal tooth 2-2 of sawtooth stop ring 2 and swivel nut 1 to good; mode by extruding embeds the external tooth 2-1 of sawtooth stop ring 2 in the big hole wall of the step type blind hole of matrix 3 into; can make sawtooth stop ring 2 and matrix 3 interlockings be one like this; make the stop tooth 1-1 engagement of the internal tooth 2-2 and the swivel nut 1 of sawtooth stop ring 2 simultaneously; can prevent effectively like this when bolt 4 being screwed into or back-outing swivel nut 1; transmission takes place in swivel nut 1 in matrix 3, thereby also can protect the tapped hole of matrix 3 injury-free effectively (as shown in Figure 1).During making, make the material hardness of swivel nut 1 and sawtooth stop ring 2 and hardness and the intensity that intensity all is higher than matrix 3 materials.Generally, the material of swivel nut 1 and sawtooth stop ring 2 preferably adopts the 40CrNiMoA hardening high-strength steel to get final product.
