Description
Technical field
The utility model relates to a kind of inner chamber and reprocesses frock, and particularly bypass class inner cavity of component reprocesses universal fixture.
Background technology
Bypass class design of part basic simlarity, is and there is nipple joint mouth or inner chamber pressure inlet at square surfaces.Because other channel part mainly connects with pipeline, reliable in order to ensure to connect sealing, the surface roughness requirements of pressure inlet inner chamber profile is very high (Ra1.6).But, because part can produce on surface, shape chamber the defect that cut etc. affects sealing in processing, turnover, measuring process.For this reason, need to increase after processing, always having examined to reprocess operation, polishing is carried out in internal lumen type face, to meet part instructions for use.
Along with the increase of task amount and the raising to the requirement of bypass class surface quality of workpieces, inner cavity of component reclamation work amount increases greatly.According to statistics, the other channel part 90% of production needs could meet part instructions for use through reprocessing polishing.Due to the restriction of bypass class design of part, need to adopt built-up jig to carry out clamping in manufacturing process, just can complete the processing of whole part.Welding five-way as shown in Figure 1, its structure for have 2 side mouths and 1 inner chamber to connect mouth on tetragonal body, the surface roughness Ra 1.6 of inner chamber profile.In part process, according to the difference of working position, need the different built-up jig of employing at least three kinds to carry out clamping and just can complete the processing that part respectively connects mouth.Adopt built-up jig clamping, if initial workpiece metering is defective after part processing, then needs to readjust fixture, again process, duplicate measurements, till accessory size and the accuracy of form and position meet design drawing requirement.Built-up jig clamping precision is low, clamping inefficiency.
If when reprocessing inner chamber profile, still adopting built-up jig clamping, not only increasing labour intensity, and clamping precision is difficult to ensure.Meanwhile, because built-up jig component part is more, in clamping process, very easily cause the collision of product and fixture, scuffing etc., again increase the amount of reprocessing.For this reason, according to the result of other channel part, when considering that part is reprocessed, remove little, the stressed little and feature that polishing rotating speed is not high of surplus, spy devises " bypass class inner cavity of component reprocesses universal fixture " simultaneously.This frock is adopted to carry out bypass class parts fixation, can not only Reliable guarantee parts fixation positioning precision, and can greatly improve clamping efficiency, reduce labour intensity, improve part and reprocess efficiency, reduce part and reprocess cost.
Summary of the invention
Technology of the present utility model is dealt with problems and is: provide a kind of bypass class inner cavity of component to reprocess universal fixture, can Reliable guarantee parts fixation positioning precision, greatly improves clamping efficiency, reduces labour intensity, improves part and reprocesses efficiency.
The technical solution of the utility model is: design a kind of bypass class inner cavity of component and reprocess universal fixture, comprises opening tire 1, location and coordinates lining 2 and hold-down bolt 3; Opening tire 1 is a cylinder, and outer wall is that secondary is stepped; Opening tire 1 inside has secondary stepped throughhole in the axial direction, and the bigger diameter end of opening tire 1 outer wall corresponding to miner diameter end in this secondary stepped throughhole; Opening tire 1 miner diameter end matches with machine tool jaw, and the end face of opening tire 1 miner diameter end is provided with screwed hole, and screwed hole place axis direction and opening tire 1 axis are parallel to each other; Location and coordinate lining 2 be stepped cylinder, its inside in the axial direction on have through hole; In the stepped throughhole of location and cooperation lining 2 insertion opening tire 1, and match with the stepped throughhole of opening tire 1, the processed position of part to be processed is inserted location and is coordinated in the through hole of lining 2, and is fixed by hold-down bolt 3.
Further technical scheme of the present utility model is: the upper shed of opening tire 1 outer wall, and opening runs through opening tire 1 two ends and outer wall, and axis and opening tire 1 axis of opening are parallel to each other.
Further technical scheme of the present utility model is: described location and cooperation lining 2 are the stepped cylinder of secondary.
Further technical scheme of the present utility model is: opening tire 1 adopts aluminum alloy materials to make.
Further technical scheme of the present utility model is: hold-down bolt 3 adopts fluoroplastics to make.
Invention effect
Technique effect of the present utility model is:
(1) clamp by opening tire with coordinating of lining and ensure positioning precision.
(2) greatly improve clamping efficiency, reduce labour intensity, improve part and reprocess efficiency, reduce part and reprocess cost.

Detailed description of the invention
Below in conjunction with concrete embodiment, technical solutions of the utility model are further illustrated.
1, in Fig. 1-Fig. 6, the utility model comprises three parts: opening tire 1, location and cooperation lining 2, hold-down bolt 3; Opening tire 1 is two stage steps column, circumferentially has square three-way groove, and axially have three grades of step through-holes, its small end external diameter coordinates with lathe three-jaw, and clamping, on lathe, has screwed hole in square groove side in addition, coordinates with hold-down bolt 3; Location and cooperation lining 2 are two stage steps column, and it axially has through hole, and through hole one end is processed with screw thread, and location and cooperation lining 2 external diameter coordinate with opening tire 1 stepped hole, and the processed position of part to be processed is stretched out from location and cooperation lining 2 through hole; Hold-down bolt 3 end of thread screws in the corresponding screwed hole of opening tire 1, is pressed on by part on opening tire.By changing different location and coordinating lining, carry out the clamping of different parts.Location and cooperation lining are installed in the center stepped hole of opening tire, and its effect is that locating element reprocesses position, in order to ensure the axiality of working position.Opening tire and hold-down bolt with the use of, part is fixed in frock, it is arranged on lathe by three-jaw and processes.Adopt aluminium alloy and fluoroplastics as frock material, not only low price, and adopt fluoroplastics to contact with part can to avoid that part is scratched, gouge, effectively avoid the generation repeating to reprocess.Take scroll chuck as starting point, according to the self-centering principle of three-jaw, with opening tire for matrix designs.Location and cooperation lining are installed in the center stepped hole of opening tire, reprocess position, ensure the axiality of working position in order to locating element.Opening tire and hold-down bolt with the use of, part is fixed in frock, is arranged on lathe and processes.By changing different location and coordinating lining, the clamping of different parts can be carried out.Wherein locate and coordinate lining to mainly contain two kinds: internal thread lining and step lining.Opening tire adopts aluminum alloy materials to make, and hold-down bolt adopts fluoroplastics to make, not only low price, and fluoroplastics contact with part, can avoid that part is scratched, gouge, effectively avoids the generation repeating to reprocess.
The inner chamber of the cubic part of polishing, concrete implementation step is as follows:
(1) choose location that the circumscribed circle diameter corresponding with cubic part match and coordinate lining 2, its by with cubic seamed edge contact gripping part;
(2) by location and coordinate lining 2 to be arranged in opening tire 1 in stepped hole;
(3) part will be reprocessed to be arranged on opening tire 1, and reprocess position and stretch out in location and cooperation lining 2;
(4) be fixed in frock with hold-down bolt 3 by part, the end of thread four uniform screwed holes from opening tire 1 stretch out, and assembly relation as shown in Figure 1;
(5) frock and part are arranged on lathe, fix with three-jaw, process.
