Description
Technical field
The present invention relates to mechanical positioner fields, and in particular to a kind of reducing disintegration formula positioning pin.
Background technique
Many product department's sets are point half formula structure, such as cylinder, diaphragm housing ring, balance ring in steam turbine product etc., many
Process needs merging phase to carry out (such as processing inner hole, outer circle), to generate relative displacement when avoiding upper and lower half from merging, needs
It is positioned using pin.
In currently available technology, the positioning pin used is clearance fit between monolithic construction, with pin hole, is generally had
The diametric clearance of 0.03mm -0.10mm or so merges step are as follows: first plant positioning pin into lower half, then fasten upper half；It dismantles
Step are as follows: after removing portion's set upper half, extract positioning pin.It has the disadvantage that in use
1. being clearance fit between pin and pin hole, phenomenon of grinding one's teeth will lead to during portion covers and merges, and then lead to machine
Tool processing dimension inaccuracy；
2. when separating upper and lower half, especially as the large-scale portion set in steam turbine product, crane etc. is auxiliary in disassembly process
Assistant engineer's dress cannot reach absolutely steady, will lead to positioning pin and the mutual card plug of pin hole, and then generate pin, pin hole plucking phenomenon；
In conclusion the phenomenon of grinding one's teeth that the clearance issues between existing positioning pin and pin hole generate, not up to expected
Clearance fit, and there is plucking phenomenon between the pin and pin hole in unpack procedure because lifting by crane unstable generation, it is fixed not to be able to satisfy
Position pin length and positioning pin outer diameter demand, to adapt to the problem of different occasions need.
Summary of the invention
The present invention is the phenomenon of grinding one's teeth for solving the clearance issues between existing positioning pin and pin hole and generating, not up to expected
Clearance fit, and there is plucking phenomenon between the pin and pin hole in unpack procedure because lifting by crane unstable generation, be not able to satisfy
Positioning pin length and positioning pin outer diameter demand to adapt to the problem of different occasions need, and propose that a kind of reducing disintegration formula is fixed
Position pin.
A kind of reducing disintegration formula positioning pin of the invention, composition include shank, guide, boss, stud and plunger；
Shank and plunger are cylindrical shape, and an end face of shank is fixedly connected with one end of boss, and boss and shank are same
Axis is arranged, and stud is equipped at the other end center of boss, is equipped with threaded hole at an end face center of plunger, one end of shank passes through
Guide is connect with the threaded one end of plunger, and the other end of shank is equipped with regular hexagonal prism；
Further, one end of the shank is equipped with taper；
Further, the wall body cross-sectional shape of the guide is right-angled trapezium, and the inner sidewall bus and axis of guide
Angle between line is a, 0 ° of a≤45 ° <；
Further, the cooperation section of shank and the guide is equipped with taper；
Further, the stud length on an end face of the shank is 10mm~20mm；
Further, an end face of the plunger is equipped with annular ridge, and one end clearance fit with guide；
Further, the outer wall of the guide is equipped with strip through slot in the axial direction；
Further, when in use, this positioning pin is applied in Fen Ban formula product department set, and specific there are two types of usage modes:
When mode one, a point half formula portion set merge: plunger screw-in portion being covered lower half, guide is put in plunger fixed；It screws in
Shank, with guide taper fit, is gradually increased guide outer diameter during shank screws in plunger, screws in distance by regulation,
Controllable guide outer diameter；When guide outer diameter reaches certain value, at this time with pin hole there are certain interval, on fastening
Half, continue to screw in shank, so that guide and portion is covered pin hole and reach zero clearance.
When mode two, a point half formula portion set are dismantled: when dismantling, by screwing out shank, guide outer diameter being become smaller, between pin hole
When gap reaches certain value, shank, guide, plunger are taken out；After pin to be positioned takes out, dismounting portion covers upper half；
It can be by regulating and controlling shank, guide taper size, to meet positioning pin length and positioning pin outer diameter demand, to adapt to not
It is needed with occasion.
Compared with the prior art, the invention has the following beneficial effects:
One, the shortcomings that the present invention overcomes the prior arts is connect with 2 taper fit of guide using one end of shank 1, then led to
It crosses shank and plunger rotates adjustment length, meet positioning pin length and positioning pin outer diameter demand, to adapt to different occasion needs.
Two, the present invention becomes smaller 2 outer diameter of guide using by back-out shank 1, when reaching certain value with pin hole gap,
Shank 1, guide 2, plunger 3 are taken out；After pin to be positioned takes out, dismounting portion covers upper half, avoids in unpack procedure because of lifting
There is plucking phenomenon between the pin and pin hole of unstable generation.
Three, the shortcomings that the present invention overcomes the prior arts is connect with 2 taper fit of guide using one end of shank 1, then led to
It crosses shank and plunger rotates adjustment length, avoid the phenomenon of grinding one's teeth that the clearance issues between positioning pin and pin hole generate, reach
Expected clearance fit.
