Description
Technical field
The utility model belongs to linear cutting equipment field, and in particular to a kind of feed screw nut.
Background technique
Feed screw nut used in traditional wire cutting machine tool Wire-conveying mechanism of quick walk is monoblock type copper nut, the silk as used in Wire-conveying mechanism of quick walk
Thick stick is angular thread precision lead screw, and threads of lead screw surface is quenched (hardness is high), and the hardness of copper is low, so traditional
Wire transporting feed screw nut wears no resistance, high failure rate, and maintenance replacement frequency is high.
Summary of the invention
In view of the deficienciess of the prior art, the utility model provides, a kind of assembly precision is high, durable feed screw nut.
The utility model is achieved through the following technical solutions：
A kind of feed screw nut, including flange sleeve, nut cover and locking nut, is provided with screw hole on the flange sleeve front end face,
It is socketed the tight split nut on the outside of the screw hole, a pair of and screwhole position is provided on the anchor ring of the tight split nut front end
Corresponding arc-shaped slot is provided with fillister head screw in the arc-shaped slot, and described fillister head screw one end is set by plain washer
It sets on the outside of the arc-shaped slot, the other end connects the screw hole, and the flange sleeve bottom inside is socketed with the nut set, institute
It states flange sleeve bottom and top and has pin hole, the fixed nut set of straight pin, the nut are provided in the pin hole
Oilhole is provided in the flange sleeve between set and the locking nut.
The locking nut is identical as the aperture for the internal screw thread that the nut covers and the diameter of axle.
The locking nut periphery is provided with reticulate pattern.
The locking nut material preferably uses brass ZH62.
The nut cover material preferably uses nylon PA-66.
Compared with prior art, the utility model has the beneficial effects that：The utility model uses two kinds of materials of copper and nylon
The design combined greatly promotes whole service life using the wearability of nylon material and the impact resistance of copper；Meanwhile
The design of locking nut can effectively adjust the axial thread gap between the utility model and lead screw during installation, improve assembly
Precision, to guarantee the stabilization of cutting processing.

Specific embodiment
If Fig. 1 is to a kind of feed screw nut shown in fig. 6 in Figure of description, including flange sleeve 1, nut set 2 and locking screw
Mother 3 is provided with screw hole 4 on 1 front end face of flange sleeve, tight split nut 3 is socketed on the outside of screw hole 4, is opened on the anchor ring of tight 3 front end of split nut
There is a pair of arc-shaped slot 5 corresponding with 4 position of screw hole, is provided with fillister head screw 6,6 one end of fillister head screw in arc-shaped slot 5
By the setting of plain washer 7 in 5 outside of arc-shaped slot, the design of other end connecting screw hole 4, locking nut 3 can during installation effectively
The axial thread gap between the utility model and lead screw is adjusted, assembly precision is improved, to guarantee the stabilization of cutting processing.
1 bottom inside of flange sleeve is socketed with nut set 2, and 1 bottom and top of flange sleeve have pin hole 8, set in pin hole 8
Be equipped with 9 fixture nut of straight pin set 2, be provided with oilhole 10 in the flange sleeve 1 between nut set 2 and locking nut 3, guarantee screw rod with
Lubrication between the utility model.
Locking nut 3 is identical as the aperture of the internal screw thread of nut set 2 and the diameter of axle, guarantees the tight fit with screw rod.
3 periphery of locking nut is provided with reticulate pattern 11, and when assembly has antiskid function.
3 material of locking nut preferably uses brass ZH62, and nut covers 2 materials and preferably uses nylon PA-66, utilizes nylon material
The wearability of material and the impact resistance of copper, greatly promote whole service life.
In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation
Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair
Decorations, should be included in the scope of the claims of the utility model.
