Description
Technical field
This utility model relates to a kind of securing member, positions nut particularly to one.
Background technology
Along with the industrial revolution and the progress of science and technology, the automatization level of production is more and more higher, accordingly
Automaticity and precision more and more higher.The displacement of parts and location use the comparison of screw rod transmission
Generally.Positioner moves on screw mandrel frequently, causes a certain degree of abrasion, and tradition is changed
The parts of abrasion then need to stop producing, and remove high-precision drive lead screw, then remove positioning element,
Change location nut, thus affect production, reduce the economic benefit of enterprise.And conventional location nut
By structure influence, fixed effect is poor, uses for a long time or easily gets loose in vibration environment, causing portion
Part moves, and affects equipment precision and even causes security incident.

Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model embodiment is discussed in detail.
Refering to Fig. 1 to Fig. 4, this utility model provides one location nut, and it includes nut body 1
And it is fixed on the locating piece 2 of nut body 1 (bottom) end, nut body offers screw
101, locating piece is the most cylindrical, offers the centre bore 20 coaxial with screw on locating piece 2,
And the diameter of this centre bore is more than the big footpath of screw, the sidewall of locating piece extends radially outwardly and forms location
Portion, extends vertically through small top and big bottom shoulder hole on location division, and the axis of this shoulder hole is put down
Row in the axis of centre bore, and shoulder hole at least two and circumference uniform, in the present embodiment, circumference
Being evenly equipped with four, the end face in location division is fixed with gland 201, and this gland is bonded by high-temperature metal
Agent is fixed on location division, is equipped with alignment pin 3 in each shoulder hole, and the sidewall at alignment pin sets
Having annular stop projection 301, the head of this alignment pin is inclined-plane and extends downward outside shoulder hole, should
Inclined-plane is inserted in towards the tightening direction of nut body, the afterbody offering appearance alignment pin on gland simultaneously
Hole 202, between gland and annular stop projection, be provided with spring 302, this spring makes alignment pin oriented
Under movement tendency；In order to improve operational reliability, it is to avoid alignment pin rotates, determining in the present embodiment
The cross section of position pin is regular polygon or ellipse；Assemble for convenience, set in the upper surface of location division
There is positioning convex, on gland, be provided with the location hole corresponding with positioning convex simultaneously；In order to improve structure
Intensity also reduces production cost, and nut body is one-body molded with locating piece；In order to improve operation further
Reliability, is provided with the sleeve that cross section is regular polygon, now, rank in the upper end macropore of shoulder hole
The cross section of ladder hole upper end hole is identical with the shape of cross section of sleeve, and alignment pin upper end is set in sleeve,
