Abstract
The utility model discloses a super-fine procedure supporting jig, which comprises an outside diameter supporting jig and an inside diameter supporting jig composed of supporting heads and supporting seats, the supporting heads are made by ceramic materials, and the supporting seats of the inside diameter supporting jig are arranged evenly by the three-point means; and are connected with the supporting seats of the outside diameter supporting jig by a connecting body. The supporting heads are made of ceramic materials, thereby well solving the problems of supporting prints and scoring. The supporting heads are in bonding connection with the connecting body, thereby forming the modularized interchanging mode with concision and economy. The partial geometric accuracy of a super-fine channel is improved due to the new centering function of the outside diameter supporting jig. Supporting points supported by the inside diameter adopt the uniform three-point mode and are provided with arc grooves, therefore the stress on the inside diameter surface of the workpiece is reduced and even relative to the current two-point type one, thus avoiding the friction to the supporting body. The supporting jig reduces the supporting weight, and can store and lead super-essential oil and lubricate the support and the inside diameter contact surface, thereby reducing the friction force and perfecting the cooling effect.
Description
Technical field
The utility model top order belongs to the supporting fixture technical field of bearing processing, and what relate generally to is a kind of super Seiko preface supporting fixture.
Background technology
At present, in Production of bearing, because the working method of supporting fixture is limit, cause workpiece the quality problems of Zhi Chengyin and scuffing to occur in the particularly super Seiko preface, it is mainly relevant with supporting overall structure mode with the used material of supporting head to trace it to its cause.The material that traditional supporting head 2 adopts is essentially carbide alloy or bakelite and nylon material, often easily causes workpiece 1 external diameter or inside diameter surface the supporting marking to occur, need return external diameter or internal diameter operation and grind.When serious even the degree of depth occurs and scratch and cause waste product.Because supporting head 2 is (shown in the Fig. 4-5) that are welded on the supporting base 3, has increased the replacing difficulty thus, after supporting head 2 wearing and tearing, often need to scrap together with supporting base 3 integral replacings, cause unnecessary waste.Because the supporting head 2 of external diameter supporting is directly fixedlyed connected with supporting base, can not realize the aligning function, it is not satisfactory therefore the partial geometry precision of super smart raceway groove to be improved effect.Because the internal diameter supporting is 2 non-even distribution types (shown in Fig. 5-6), can cause workpiece 1 inside diameter surface to produce friction phenomenon because of discontinuity.And because of this supporting is entity, hold the used supporting of model for the processing larger axis, its bodily form weight heaviness is changed for the on-the-spot regulation and control of workman and is brought inconvenience.
Summary of the invention
The purpose of the utility model project is to propose a kind of improved super Seiko preface supporting fixture.Solving supporting fixture causes workpiece the problem of Zhi Chengyin and scuffing and replacing difficulty to occur.Improve super extract Iuality, improve the geometric accuracy of super smart outer raceway groove, be convenient for changing supporting head, avoid waste.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: the external diameter supporting fixture is made of supporting head, connector and supporting base, and supporting head is connected with supporting base by connector; The internal diameter supporting fixture is made of supporting head and supporting base, and supporting head is connected with supporting base is bonding.
The utility model supporting head adopts ceramic material, and is not only cheap, and little because of its density, intensity is high, elastic modelling quantity is high, thermal coefficient of expansion is little, wear-resisting, high temperature resistant, corrosion resistant characteristic, preferably resolves the problem of Zhi Chengyin and scuffing.And it is that bonding mode is connected with connector, has formed the modularization interchangeabling form with supporting base or connector, and is succinct economical.Because the connector of external diameter supporting fixture adopts V-type floating type, has increased the aligning function, therefore improved the partial geometry precision of super smart raceway groove.Because the supporting-point of internal diameter supporting adopts 3 even distribution types, the stressed existing relatively two point form in workpiece diameter surface is reduced and evenly, and can not produce the possibility of friction supporting base.And on supporting base, be provided with the uniform arc groove in three places, and groove not only alleviates the weight of supporting, and can save and dredge super essential oil, thus lubricated supporting and internal diameter contact-making surface reduce friction and make the cooling heat dissipation better effects if.
The new and old supporting processing characteristics of its external diameter (model: 6212E/01) that relatively sees the following form

The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1: present embodiment external diameter supporting fixture is made of supporting head 2, supporting base 3 and connector 4, supporting head 2 is selected ceramic material for use, its profile is block, is symmetricly set in two grooves of V-type end face of connector 4, adopts the glue bonding mode fixedly connected.The front end of connector 4 is a V-structure, and itself and supporting base 3 form floating type connected mode by rivet, have increased the aligning function thus, have improved the partial geometry precision of super smart raceway groove.
As Fig. 2 in conjunction with shown in Figure 3: present embodiment internal diameter supporting fixture is made of supporting head 2 and supporting base 3, supporting head 2 adopts ceramic material, its profile is block, is 3 even distribution type settings at the cylindrical end face of supporting base 3, adopts the glue bonding mode fixedly connected.Be equipped with arc groove 5 at supporting base 32 adjacent of two supporting heads.
