Abstract
A kind of square guide post guide sleeve is the utility model is related to, includes the guide pillars and bushes of mutual cooperation, guide post is in flat column, the section of guide post is square, guide sleeve is equipped with through hole corresponding with guide post, and guide post is extend into the through hole of guide sleeve, and the medial plane of guide post and the inner wall of through hole are in close contact.The square guide post guide sleeve of the structure is contacted with face, contact area is big, it is not easy to wear, stability is good, service life guide post guide sleeve more round than market improves more than three times, fit precision can accomplish the shortcomings that zero is low to the fit precision between 0.015mm, effectively solving existing market upper guide post guide sleeve, and stability is poor.
Description
Technical field
Hardware dies field is the utility model is related to, especially a kind of square guide post guide sleeve.
Background technology
Guide post guide sleeve structure can be all used in hardware dies field to complete guiding action, guide post guide sleeve currently on the market
All it is round structure, the fit precision of round structure is between 0.01mm to 0.03mm, and 1:Since traditional city's guide pillars and bushes leads to
Absolute circle is not accomplished in processing in hole.2:Circular guide post guide sleeve, which coordinates, does not zero cooperation, as long as there is gap just to have big roundlet,
Contact of the arc surface with arc surface is not accomplished forever.Therefore when guide post coordinates with guide sleeve, all it is line contact, does not accomplish at all really
Arc surface contact, the round cooperation contact site of traditional guide post and guide sleeve is straight line, since contact portion area is small,
It is easy to wear, fit precision is deteriorated soon.Being stitched between the cooperation of round guide post guide sleeve just becomes very big, and guide effect is deteriorated,
Since the fit precision of mould fuse is higher, guiding accuracy is worse than fuse precision, and fuse power angle easily collides, and fuse is quickly
With regard to damage.So the rate that repairs a die is very high, and production efficiency is with regard to low.
Utility model content
The purpose of this utility model is to solve defect existing in the prior art, there is provided a kind of square guide post guide sleeve.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of square guide post guide sleeve, includes the guide pillars and bushes of mutual cooperation, and guide post is in flat column, and the section of guide post is side
Shape, guide sleeve are equipped with through hole corresponding with guide post, and guide post is extend into the through hole of guide sleeve, the medial plane of guide post and through hole it is interior
Wall is in close contact.
A kind of above-mentioned square guide post guide sleeve, the four corners of the guide post are equipped with chamfering.
A kind of above-mentioned square guide post guide sleeve, the section of the through hole is square, the medial plane and through-hole wall of guide post
Between clearance fit precision be 0-0.015mm.
A kind of above-mentioned square guide post guide sleeve, the section of the through hole is square, and the section of the guide post is square.
The beneficial effects of the utility model are:The square guide post guide sleeve of the structure is contacted with face, and contact area is big, is not easy to grind
Damage, stability is good, and service life guide post guide sleeve more round than market improves more than three times, and fit precision can accomplish that zero arrives
Between 0.015mm, effectively solves the shortcomings that fit precision of existing market upper guide post guide sleeve is low, and stability is poor.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model guide post;
Fig. 2 is the schematic cross-section of the utility model guide post;
Fig. 3 is the schematic diagram of the utility model guide sleeve.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of square guide post guide sleeve, includes the guide post 1 and guide sleeve 2 of mutual cooperation, and guide post 1 is in
Flat column, the section of guide post 1 is square, and guide sleeve 2 is equipped with through hole 3 corresponding with guide post, and guide post 1 extend into the through hole 3 of guide sleeve 2
Interior, the medial plane 4 of guide post 1 is in close contact with the inner wall of through hole 3.
Further, the four corners of guide post 1 are equipped with chamfering, and the section of through hole 3 is square, the medial plane 4 and through hole of guide post 1
Clearance fit precision between 3 inner walls is 0-0.015mm, and the section of through hole is square, and the section of guide post is square.
