Description

Drive plate assembling abnormity nut

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。

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。
