Description

A kind of drive bevel gear tooth Profile Machining bipyramid positioning tool
Technical field
The utility model relates to bevel gear shaft manufacture fields, and in particular to a kind of tooling of machining of bevel gears tooth form.
Background technique
Automobile axle drive bevel gear tooth Profile Machining process include slightly cut, fine cut, it is hot before inspection, pairing, gear lapping, roll flute work Sequence.Work process, which needs to bore using list, clamps workpiece tail portion, and there are drawbacks: the first, product in existing single cone clamping use process Workpiece can cause workpiece to scrap by ticking in process;The second, workpieces processing is two-point locating, and positioning accuracy is poor, product It is off quality.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, it is fixed to provide a kind of drive bevel gear tooth Profile Machining bipyramid The problem of position tooling, the problem of being able to solve drive bevel gear tooth Profile Machining Process Precision and workpiece are ticked.
The technical solution of the utility model is achieved in that a kind of drive bevel gear tooth Profile Machining bipyramid positioning tool, Including positioning sleeve, positioning sleeve is connected with ontology by bolt, and ontology is equipped with the first pressure contact portion, the first pressure contact portion and bipyramid spring First cone of collet one end cooperates, and the double-cone spring chuck other end is equipped with the second cone, and the of the second cone and end of helping pull a cart The cooperation of two pressure contact portions, double-cone spring chuck and drawing are set in the inner hole of ontology.
The double-cone spring chuck is the collet of spring steel material, and double-cone spring chuck is equipped with several flutings.
The fluting is axially parallel with double-cone spring chuck.
In the utility model, double-cone spring chuck both ends clamp two axis behind drive bevel gear under taper fit effect Neck position forms three-point fix with workpiece positioning sleeve fixed position, and tooth Profile Machining process meets processing request, work in process Part, which will not be ticked, to be come.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of drive bevel gear.
Fig. 3 is locating sleeve structure schematic diagram.
Fig. 4 is the schematic diagram of double-cone spring chuck.
Fig. 5 is the schematic diagram helped pull a cart.
Fig. 6 is body construction schematic diagram.
Wherein: 1. drive bevel gears, 2. positioning sleeves, 3. ontologies, the first pressure contact portion of 3-1., 4. double-cone spring chucks, 4-1. First cone, the second cone of 4-2., 4-3. fluting, 5. help pull a cart, the second pressure contact portion of 5-1..
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in figs. 1 to 6, a kind of drive bevel gear tooth Profile Machining bipyramid positioning tool, including positioning sleeve 2, positioning sleeve 2 with Ontology 3 is connected by bolt, and ontology 3 is equipped with the first pressure contact portion 3-1, the first pressure contact portion 3-1 and 4 one end of double-cone spring chuck First cone 4-1 cooperation, 4 other end of double-cone spring chuck are equipped with the of the second cone 4-2, the second cone 4-2 and 5 ends of helping pull a cart Two pressure contact portion 5-1 cooperation, double-cone spring chuck 4 and helping pull a cart 5 are arranged in the inner hole of ontology 3.
Utility model works process is as follows: during automobile axle drive bevel gear tooth Profile Machining, after hydraulic starting, drawing Set 5 tenses backward, and 4 both ends of double-cone spring chuck clamp two axle journal positions behind drive bevel gear 1 under taper fit effect, Three-point fix is formed with workpiece positioning sleeve fixed position, tooth Profile Machining process meets processing request.Wherein, taper fit process is such as Under, in 5 cinching process of helping pull a cart, the second pressure contact portion 5-1 compresses the second cone 4-2, the first pressure contact portion 3-1 and compresses the first cone 4-1.
Compared with prior art, the utility model has the advantage that 1. automobile axle drive bevel gear tooth Profile Machining mistakes Journey (slightly cut, fine cut, heat before inspections, pairing, gear lapping, roll flute process) can use bipyramid positioning tool, guarantee tooth Profile Machining The Set and Positioning consistency of process;2. Product Precision is controllable, gear lapping product profile accuracy can reach 7 grades, and roll flute Product Precision can Reach 5 grades;3. it is substantially zeroed that product is ticked probability, rejection rate is substantially reduced.
Preferably, the double-cone spring chuck 4 is the collet of spring steel material, and double-cone spring chuck 4 is equipped with several flutings 4-3.The fluting 4-3 is axial parallel with double-cone spring chuck 4.Spring steel itself has elasticity, and setting fluting is for bearing pressure Flexible deformation when power.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
