Abstract
The utility model provides a kind of new spigot nut, it is characterised in that：The middle part of the nut body of engineering plastics material has the internal thread segment of trapezoidal thread；It is die cavity positioned at the both ends of internal thread segment, one of die cavity is installed with the guide sleeve with smooth inner wall through hole；Another die cavity is the internal thread segment of vacant die cavity or the trapezoidal thread being connected provided with the internal thread segment with middle part or is installed with the guide sleeve with smooth inner wall through hole or is arranged with side wall and offers the wedge shape of groove and disappear gap half-nut.The guide sleeve is that interference fit is installed in die cavity, or guide sleeve is that bonding is installed in die cavity.The utility model coordinates transmission nut using both ends guide sleeve or the gap half-nut that disappears, the defects of overcoming both, screw rod engages through nut with internal thread during work, screw rod is cylindrical simultaneously coordinates with front and rear guide sleeve or the gap nut sleeve inwall that disappears, and the device can realize radially-directed while screw thread auxiliary driving is provided and axially eliminate drive gap.
Description
Technical field
A kind of nut is the utility model is related to, specifically a kind of structure of sliding nut.
Background technology
Sliding nut has engineering plastics injection molding and engineering plastics machinery from processing technology division is general in the market
Processing and fabricating two types.The nut of injection molding, screw thread uniformity is preferable, but generally radially gap is larger for its screw pair；
The nut that another kind machining makes, although radial clearance controllability is good, screw thread uniformity is poor.Sliding nut is consolidated simultaneously
Some axial gap is also to influence a key factor of sliding screw auxiliary driving precision.
Utility model content
The utility model provides a kind of new spigot nut, the purpose is to solve prior art shortcoming, is providing screw thread pair
Radially-directed is realized while transmission and axially eliminates drive gap.
Technical scheme is used by the utility model solves its technical problem：
A kind of new spigot nut, it is characterised in that：The middle part of the nut body of engineering plastics material has trapezoidal thread
Internal thread segment；It is die cavity positioned at the both ends of internal thread segment, one of die cavity is installed with the guiding with smooth inner wall through hole
Set；Another die cavity is the internal thread segment or solid of vacant die cavity or the trapezoidal thread being connected provided with the internal thread segment with middle part
Provided with the guide sleeve with smooth inner wall through hole or it is arranged with side wall and offers the wedge shape of groove and disappear gap half-nut.
The guide sleeve is that interference fit is installed in die cavity, or guide sleeve is that bonding is installed in die cavity.
It is of the present utility model to be beneficial in that：
The utility model coordinates transmission nut using both ends guide sleeve or wedge shape the gap half-nut that disappears, and screw rod passes through during work
Nut engages with internal thread, while screw rod is cylindrical with front and rear guide sleeve or the gap nut sleeve inwall that disappears coordinates, and the device can provide
Radially-directed is realized while screw thread auxiliary driving and axially eliminates drive gap.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the three-dimensional exploded view of the utility model embodiment 1；
Fig. 2 is the sectional view of the utility model embodiment 1；
Fig. 3 is the three-dimensional exploded view of the utility model embodiment 2；
Fig. 4 is the sectional view of the utility model embodiment 2；
Embodiment
In order to illustrate more clearly of the technical solution of the utility model, the required accompanying drawing used in description will be made below
Simply introduce, it should be apparent that, drawings in the following description are only some embodiments of the utility model, for this area
For those of ordinary skill, on the premise of not paying creative work, other implement can also be obtained according to these accompanying drawings
Example.
The utility model embodiment 1 as shown in Figure 1 and Figure 2：
There is the nut body 1 of the internal thread segment 13 of trapezoidal thread, preceding guide sleeve 2, the three parts group of rear guide sleeve 3 by middle part
Into.
Nut body 1 is that Acme screw threads can be selected by engineering plastics injection molding, the form of thread of internal thread segment 13, or
The trapezoidal motion thread of other thread form angles.The both ends that nut body 1 is located at internal thread segment 13 are die cavity 11,12.
Preceding guide sleeve 2, the material of rear guide sleeve 3 can select engineering plastics or metal material according to demand.The preceding mistake of guide sleeve 2
Cooperation of being full of is pressed into or sticks at die cavity 11 with adhesive and be installed in die cavity 11.Afterwards guide sleeve 3 interference fit press-in or with bond
Agent sticks at die cavity 12 and is installed in die cavity 12.
The internal face 21 of guide sleeve 2, the internal face 31 of guide sleeve 3 respectively with screw mandrel major diameter fit, the interior spiral shell of nut body 1
Line section 13 and screw mandrel engagement, the smooth degree of screw pair operation depend on the coaxial of internal face 21, internal face 31 and internal thread segment 13
Degree, and the dimensional tolerance of internal face 21 and internal face 31.
The device can realize radially-directed while screw thread auxiliary driving is provided, and its precision being oriented to depends on front and rear be oriented to
Cover the dimensional tolerance and behavior tolerance of endoporus.
The utility model embodiment 2 as shown in Figure 3, Figure 4：
Preceding guide sleeve 2 is substituted for side wall offers the wedge shape of groove 43 and disappear gap half-nut 4, wedge shape disappears gap half-nut 4
Outer wall 42 is wedge shape, (the gap half-nut 4 that can also be disappeared with wedge shape replace after guide sleeve 3), and wedge shape disappears the interference fit pressure of gap half-nut 4
Enter or stick at die cavity 11 with adhesive and be installed in die cavity 11.The interference fit of guide sleeve 3 is pressed into or sticks at type with adhesive afterwards
Chamber 12 and be installed in die cavity 12.The internal face 31 of guide sleeve 3 and screw mandrel major diameter fit afterwards, the spiral shell that wedge shape disappears on gap half-nut 4
Line 41 engages with screw mandrel, and due to its wedge-shaped notching construction, the wedge shape gap half-nut 4 that disappears can hold screw mandrel tightly when be pressed into die cavity 11, easypro
Zhang Shiyu nut bodies 1 push away, between the axial direction of contraction and the diastole control screw mandrel deputy thread cooperation of gap half-nut 4 that disappeared by wedge shape
Gap, so as to realize the gap that axially disappears.
In other embodiments, a die cavity is guide sleeve, and another die cavity is for vacant die cavity or provided with the ladder with middle part
The internal thread segment for the trapezoidal thread that the internal thread segment of shape screw thread is connected.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.To the upper of the disclosed embodiments
State bright, professional and technical personnel in the field is realized or using the utility model.A variety of modifications pair to these embodiments
It will be apparent for those skilled in the art, generic principles defined herein can not depart from this reality
In the case of with new spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this
These embodiments shown in text, and it is to fit to the most wide scope consistent with principles disclosed herein and features of novelty.
