The utility model provides a pair of it uses special -shaped nut to drive board assembly can directly make by enough cold upsetting process, and follow -up machining processes only need do simple repairment and can accomplish, is applicable to the installation that drives the board, has reduced the waste that comes of raw and other materials, has practiced thrift manufacturing cost.
Description
Technical field
This utility model belongs to five metals spare and accessory parts technical field, specifically just relates to a kind of drive plate assembling abnormity nut。
Background technology
Machinery industry generally use various hardwares as processing and install, such as securing member is exactly a kind of common hardware, securing member securing member commercially also referred to as standard component be two or more parts or component are fastenedly connected become one overall time the general name of class machine components that adopts。Its feature is that description various performance purposes is different and standardization, seriation, unitized strong。Securing member is that most widely used mechanical basic part is in great demand。Nut is a kind of common securing member, the common nut of tradition is square or hexagon, and it does not have particular/special requirement when being used for assembling for installation tool, and therefore range of application is very extensive, but these common nuts are used for generation stripped thread phenomenon of skidding, cause that connecting shakiness is susceptible to security incident。
Chinese patent 201020189086.4 discloses a kind of abnormity nut。The shape of this nut is to be made up of one section of coaxial big six prism and one section little six prisms, and the axle center of big six prisms is provided with screwed hole, and the axle center of little six prisms is provided with hexagonal hole。This abnormity nut adopts two sections of different size of six prisms to constitute, during use, can by the workpiece of six prism embedded rotatings, then again by nut and screw rod fastening, can effectively prevent from driving and produce to skid or obscission between axle and workpiece, improve the reliability connected, it is ensured that normal operation, it is prevented that cause equipment or personal injury。But this kind of abnormity nut needs cold heading technique and multinomial machining processes to combine just can be completed, cause raw-material waste, add the production cost of product。
Utility model content
The purpose of this utility model is aiming at the technological deficiency that in existing nut manufacture process, utilization rate of raw materials is relatively low, one is provided to drive plate assembling abnormity nut, directly can make of cold heading technique, follow-up machining processes only need to do simple finishing and can complete, it is applicable to drive the installation of plate, decrease raw-material waste, save production cost。
Technical scheme
In order to realize above-mentioned technical purpose, the one of this utility model design drives plate assembling abnormity nut, it is characterized in that: its bag nut body, described nut body includes left part, middle part and right part, and described left part, middle part and right part are cylinder, the protruding flange in described middle part and right part junction, described nut body is internal is that connecting hole is through, described connecting hole is divided into thread segment and unthreaded hole section, and described thread segment is positioned at this side of right part, described screwed hole and unthreaded hole section junction and is positioned at middle part。
Further, oblique angle is spent at described right part end face outer rim place。
Further, the oral area bevelling of described thread segment。
Further, described flange outer rim rounding。
Beneficial effect
The one that this utility model provides drives plate assembling abnormity nut, it is possible to directly make of cold heading technique, and follow-up machining processes only need to do simple finishing and can complete, it is adaptable to drives the installation of plate, decreases raw-material waste, saved production cost。

Accompanying drawing 1 is the front view of this utility model embodiment。
Accompanying drawing 2 is the right view of this utility model embodiment。
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further。
Embodiment
As shown in figure 1 and 2, a kind of drive plate assembling abnormity nut, it is characterized in that: its bag nut body 1, described nut body 1 includes left part 101, middle part 102 and right part 103, described left part, 101, middle part 102 and right part 103 be cylinder, the protruding flange 104 in described middle part 102 and right part 103 junction, described nut body 1 is internal is that connecting hole is through, described connecting hole is divided into thread segment 105 and unthreaded hole section 106, described thread segment 105 is positioned at this side of right part 103, described screwed hole 105 and unthreaded hole section 106 junction and is positioned at middle part 102。
Fall 30 degree of oblique angles at described right part 103 end face outer rim place。
The oral area bevelling of described thread segment 105。
Described flange 104 outer rim rounding。
The one that this utility model provides drives plate assembling abnormity nut, it is possible to directly make of cold heading technique, and follow-up machining processes only need to do simple finishing and can complete, it is adaptable to drives the installation of plate, decreases raw-material waste, saved production cost。
The structure of embodiment institute accompanying drawings depicted, ratio, size etc., all only in order to coordinate the disclosed content of description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the adjustment of the modification of any structure, the change of proportionate relationship or size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still drop on the disclosed technology contents of this utility model and obtain in the scope that can contain。Simultaneously, in this specification cited as " on ", D score, "left", "right", " centre ", " clockwise ", " counterclockwise " etc. term, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model。
