Abstract
The utility model discloses a kind of gate feed screw nut auxiliary structures, including screw rod and pair of nut, the pair of nut is threaded on screw rod, it further include flush end holding screw, the axial direction of the pair of nut is equipped with notch, the notch connects with the screw hole on pair of nut axle center, and the high settings such as notch and pair of nut；Threaded hole is equipped on the side wall of pair of nut, the threaded hole is arranged along the radial direction of pair of nut, and the inner port of threaded hole connects with notch, and flush end holding screw is threaded in threaded hole, and one end of flush end holding screw stretches in notch, and contradicts on the side wall of notch.The utility model stretches in pair of nut otch, one end of flush end holding screw in notch, and contradicts on the side wall of notch, and when low temperature condition is shunk, flush end holding screw can hinder the contraction of pair of nut, not will cause the case where pretightning force becomes larger.Pair of nut is opened into a notch, the processing is simple, and stability is high, at low cost, strong operability.
Description
Technical field：
The utility model relates to a kind of gate feed screw nut auxiliary structures.
Background technique：
In the prior art, feed screw nut pair is complete circle configurations, and pair of nut can generate certain in low temperature environment
Shrinking percentage causes the fit-up gap of pair of nut and lead screw to become smaller, or even generates biggish pretightning force, until it is stuck, it influences normal
Machine driving.There are also one is pair of nut slices into halves completely, set is installed additional again in pair of nut outer layer in assembly, passes through snap ring
Or screw is fixed, relatively difficult, higher cost is processed or be transformed to this mode, and more complicated.It is, therefore, desirable to provide a kind of new
Feed screw nut pair mounting technology.
Utility model content：
The utility model is to provide a kind of gate feed screw nut pair to solve the above-mentioned problems of the prior art
Structure.
Technical solution used by the utility model has：A kind of gate feed screw nut auxiliary structure, including screw rod and nut
Pair, the pair of nut are threaded on screw rod, further include flush end holding screw, and the axial direction of the pair of nut is equipped with slot
Mouthful, which connects with the screw hole on pair of nut axle center, and the high settings such as notch and pair of nut；It is set on the side wall of pair of nut
There is threaded hole, which is arranged along the radial direction of pair of nut, and the inner port of threaded hole connects with notch, flush end
Holding screw is threaded in threaded hole, and one end of flush end holding screw stretches in notch, and contradicts the side wall in notch
On.
Further, it there are two the threaded hole is set, is symmetrical arranged along pair of nut axial direction.
Further, the pair of nut is made of nonmetallic materials, and screw rod is made of metal material.
The utility model has the advantages that：
1) relative to the pair of nut of full circumferences：The utility model is by pair of nut otch, one end of flush end holding screw
It stretches in notch, and contradicts on the side wall of notch, when low temperature condition is shunk, flush end holding screw can hinder pair of nut
It shrinks, not will cause the case where pretightning force becomes larger.
2) relative to the pair of nut for cutting two halves：Pair of nut is opened a notch by the utility model, and the processing is simple, stability
Height, at low cost, strong operability.
Detailed description of the invention：
Fig. 1 is the utility model assembly structure figure.
Fig. 2 is the main structure figure of pair of nut in the utility model.
Fig. 3 is the overlooking structure figure of pair of nut in the utility model.
Fig. 4 is pair of nut sectional structure chart in the utility model.
Specific embodiment：
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1 to Figure 4, a kind of gate feed screw nut auxiliary structure of the utility model, including screw rod 100,200 and of pair of nut
Flush end holding screw 201, pair of nut 200 are threaded on screw rod 100, and notch is equipped on the axial direction of pair of nut 200
202, which connects with the screw hole on 200 axle center of pair of nut, and the high settings such as notch 202 and pair of nut 200.In spiral shell
The side wall of female pair 200 is equipped with threaded hole 203, which is arranged along the radial direction of pair of nut 200, and threaded hole
203 inner port connects with notch 202, and flush end holding screw 201 is threaded in threaded hole 203, and flush end clamp screw
One end of nail 201 stretches in notch 202, and contradicts on the side wall of notch 202.
There are two threaded hole 203 is set, it is symmetrical arranged along 200 axial direction of pair of nut.
Pair of nut 200 is made of nonmetallic materials, and screw rod 100 is made of metal material.
Flush end holding screw 201 is used to support notch 202, and pair of nut 200 is prevented to shrink, and pair of nut 200 is assemblied in lead screw
On 100.Flush end holding screw 201 prevents the contraction of pair of nut in low temperature environment, not will cause pretightning force and becomes larger.Pair of nut adds
Tooling is with simple, at low cost, stability height.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The protection scope of the utility model.
