Abstract
The invention discloses a manufacturing method of a nut used in a narrow assembling space and a tensile high-locking-force nut. In the invention, the nut with a threaded hole is manufactured into an integral structure comprising a cylinder with a threaded hole and a screwed hexagonal body with a hole; a circle of broken-neck groove is fabricated between the cylinder and the screwed hexagonal body; and the length of the cylinder of the nut body is controlled to be in a range smaller than the height of the space to be assembled; therefore, when the nut is used, the screwed hexagonal body higher that the height of the space to be assembled is unscrewed by a tool, when the screwing force reaches the required screwing value, the screwed hexagonal body is broken at the broken-neck groove to be separated from the nut naturally, thus the assembling space is released. The tensile high-locking-force nut disclosed by the invention not only has the advantage of meeting the requirement of assembly in a narrow space, but also has the advantages of convenience for use, high connection reliability, difficulty of loosening in use, and the like.
Description
Technical field
The present invention relates to a kind of preparation method and tensile type Closely locking nut that is used for narrow assembly space nut, belong to the technical field that is threaded.
Background technology
Nut is an internal thread securing member of finishing fastening function with the threaded male fastener adapted jointly.Since the bolt invention, nut also just has been born, and it and bolt are rated as a pair of heterosexual twins.But plain nut only plays the role of fastening, and does not have other function.Develop rapidly along with modern industry, nut has obtained extensive use in different field, especially in some assembly spaces narrow particular surroundings and occasion, nut has been proposed to satisfy the assembling of narrow space, the easy for installation in use again and high harsh requirement of connection reliability, and nut of the prior art is difficult to satisfy these harsh instructions for uses.
Summary of the invention
The objective of the invention is: provide a kind of and can satisfy the assembling of narrow space, can reach easy to use again, connection reliability is high, be difficult for when using loosening preparation method that is used for narrow assembly space nut and tensile type Closely locking nut take place, to overcome the deficiencies in the prior art.
The present invention is achieved in that a kind of preparation method that is used for narrow assembly space nut of the present invention is that the nut that will be threaded the hole is made into by the cylinder that is threaded the hole and has removing of smooth hole and twists the structure that hexagon is combined into one, and at cylinder with remove to twist and make the disconnected neck groove of a circle between the hexagon, the cylinder length of forming nut body is controlled at scope less than the spatial altitude that will assemble, like this when using nut, remove to twist by instrument earlier and exceed the stubborn hexagon of removing of assembly space height, when screwing force reaches needed screwing force, remove and twist hexagon from disconnected neck groove disconnection, realize natural separation, thereby discharge assembly space.
A kind of tensile type Closely locking nut of Zhi Zuoing is according to the method described above, comprise the nut that is provided with screwed hole, this nut is by the cylinder that is provided with screwed hole and be provided with removing of hole and twist hexagon and form, on cylinder, also be provided with locking distortion hole, be provided with the neck groove that breaks between the hexagon with removing to twist in locking distortion hole.
Above-mentioned hole of removing in the stubborn hexagon is the smooth hole that does not have screw thread, and the aperture of smooth hole is more than or equal to the footpath, the end of screw thread in the cylinder screwed hole.
Owing to adopted technique scheme, the present invention is designed to cylinder to the change of the hexagon of plain nut, removes to twist partly to have kept the hexagon structure, and the two junction processes groove with the standard machinery method for processing.Body is a cylinder, and the state space when having saved the plain nut assembling greatly seems compact more after being seated.Remove stubborn hexagon, be seated the back natural separation, effectively realized assembling on the one hand, simultaneously, be seated the back natural separation, do not hinder body, also discharged the useful space of expection.And after the place, locking distortion hole of cylindrical nut body carries out local artificial deformation, can prevent that like this nut from when connecting use unexpected rotation taking place, thereby realize highly reliable self-locking property.The present invention compared with prior art, the present invention not only has the advantage that can satisfy narrow space assembling, but also have easy to use, connection reliability is high, be difficult for taking place advantages such as loosening when using.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiments of the invention: when making is used for the nut of narrow assembly space, make as follows, the nut that is about to be threaded the hole is made into by the cylinder that is threaded the hole and has removing of hole twists the structure that hexagon is combined into one, and at cylinder with remove to twist and make the disconnected neck groove of a circle between the hexagon, the degree of depth of disconnected neck groove can the size of needed screwing force be determined when using, when required screwing force was big, the degree of depth of its disconnected neck groove was just more shallow, otherwise dark; And the cylinder length that will form nut body is controlled at the scope less than the spatial altitude that will assemble, like this when using nut, remove to twist by instrument earlier and exceed the stubborn hexagon of removing of assembly space height, when screwing force reaches needed screwing force, remove and twist hexagon from disconnected neck groove disconnection, realize natural separation, thereby discharge assembly space.
The structure of of the present invention a kind of tensile type Closely locking nut of Zhi Zuoing comprises the nut that is provided with screwed hole according to the method described above, the screw thread of the screwed hole of this nut can be made by traditional standard method according to the needs that use, during making, nut is made into by the cylinder 1 that is threaded the hole and has removing of hole twist hexagon 2 and form, and will remove the hole of twisting in the hexagon 2 and be made into the smooth hole 5 that does not have screw thread, the aperture of this smooth hole 5 is made into footpath, the end more than or equal to screw thread in cylinder 1 screwed hole; On cylinder 1, adopt the method for machining or the method for mould extrusion modling to produce locking distortion hole 4 then, locking distortion hole 4 can be made into the groove shapes of circular arc, also be made into the oval-shaped pit shape that is evenly distributed on the cylinder 1 by 2～4, this locking distortion hole 4 is in use, method by artificial method or instrument extruding is pushed easily at 4 places, locking distortion hole, make the screwed hole of nut produce certain deformation, thereby make nut in connecting the process of using, have higher self-locking property; Produce the neck groove 3 that breaks in locking distortion hole 4 between the hexagon 2 with removing to twist then.
