Description

A kind of jig for tubing workpiece
Technical field
The present invention relates to a kind of jig for tubing workpiece.
Background technology
Jig can be divided into following a few classes by specialization classification:
1st, universal fixturing.Universal fixturing refers to normalised, can be used to process the fixture of different workpieces within the specific limits. For example, scroll chuck and four-jaw chuck, flat-nose pliers, dividing head and rotary table on milling machine etc. on lathe.This kind of folder Tool is general to be produced by professional factory, and user is supplied to frequently as machine tool accessories.Wide adaptability is characterized in, low production efficiency is main Will be suitable for single-piece, the production of small lot.
2nd, special fixture.Special fixture refers to certain procedure and the fixture that specially designs for aiming at a certain workpiece.Its feature It is compact conformation, operation is rapid, convenient, laborsaving, it is ensured that machining accuracy and production efficiency higher, but manufactures and designs the cycle More long, manufacturing expense is also higher.When change of product, fixture will be scrapped due to that cannot reuse.Product is only applicable to fix And in the larger production of batch.
3rd, general flexible jig and modular fixture.Being characterized in the subelement of fixture can change, and partial devices can be with Adjustment, to adapt to the processing of different parts.For similar part processed in batches used by fixture, referred to as modular fixture.It is general Flexible jig is compared with modular fixture, and processing object is not bery clear and definite, and the scope of application is wider.
4th, built-up jig.Built-up jig refer to by the processing request of part, by a set of prior standard component for having manufactured and The fixture that part assembles.Manufactured by specialized factory, be characterized in flexible and changeable, versatility is strong, the manufacturing cycle is short, element energy Reusability, is particularly well-suited to the trial-production and jobbing work of new product.
5th, pallet.Pallet is a kind of fixture used on transfer matic.The fixture should play clamping workpiece Effect, be integrally formed with workpiece move on to next station from a station along transfer matic again, carry out different operations plus Work.
Because itself work characteristics of all kinds of lathes and structure type are different, the structure to clamp is also correspondingly carried Different requirements are gone out.Different by the lathe for being used, fixture can be divided into again:Turning attachment, fraise jig, drill jig, boring Bed fixture, fixture for grinding machine, gear machine fixture and other jigs etc..
It is different according to the clamping power source that fixture is used, can be divided into:Manual, air-actuated jaw, hydraulically operated fixture, gas-liquid Fixture, electric fixture, magnetic fixture, vacuum fixture etc..
Jig has the effect that:
1st, machining accuracy is ensured.Installed using fixture, the mutual alignment between workpiece and lathe, cutter can be accurately determined, The positional precision of workpiece is ensured, is not influenceed by workman's technical merit that its machining accuracy is high and stable by fixture.
2nd, productivity ratio, reduces cost are improved.Fixture clamping workpiece is used, workpiece just can be made promptly to position and press from both sides without centering Tightly, unproductive time is significantly reduced;The rigidity of workpiece is improve with fixture clamping workpiece, therefore cutting data can be increased;Can To use more than one piece, multi-station clamp clamping workpiece, and efficient clamp system is used, these factors are conducive to improving work production Rate.In addition, after using fixture, product quality stabilization, percent defective declines, the workman that industrial grade can be arranged relatively low, it will be apparent that Reduce production cost.
3rd, the processing range of lathe is expanded.Can change the purposes of former lathe using special fixture and expand the use of lathe Scope, realizes one-machine-multi-function.For example, after installing boring template fixture on lathe or radial drilling machine, it is possible to which box body hole system is carried out Boring is processed;Also lathe can be changed into broaching machine by special fixture to use, to give full play to the effect of universal machine tools.
4th, the labour intensity of workman is mitigated.With fixture clamping workpiece easily and fast, when using the clamping dress such as pneumatic, hydraulic pressure When putting, the labour intensity of workman can be mitigated.
Fixture on current lathe is varied, but no matter is forever consistent, positioning accurate using how fixture standard Degree requires that high, clamping is convenient, can fully demonstrate labor productivity, saves labor operations intensity of work personnel etc..
The U of Chinese utility model patent specification CN 203792068 disclose a kind of jig of such a, including Clamp body and angle bar, the angle bar are provided with the fishbolt for clamping the clamp body, and the fishbolt is cased with double spiral shells Mother, one end of the fishbolt is machined with spheroid with holes, and the other end of the fishbolt is cased with wear block, the folder Particularly set fluted, the wear block is resisted against in the groove.The utility model by setting groove on clamp body, Wear block is set with fishbolt front end, and is provided with double nut, substantially increase the structural stability of fixture, work more may be used Lean on, can also be by screwing fishbolt in the ball that metallic rod is penetrated spheroid, it is more laborsaving, convenient to operate, and reduces work The workload of people.But this fixture needs manpower to step up, and dynamics crosses conference and damages clamped article.
The U of Chinese utility model patent specification CN 203254205 are disclosed and so know clearly a kind of jig.This practicality New drip irrigation device is:A kind of jig, mainly including taper shank, angle bar and clamp body, described taper shank and lathe Spindle hole matches, and the bottom of the taper shank is provided with screw mandrel, and the top of taper shank is provided with taper shank axis in 90 ° of angle bar, the angle bar Screwed hole is provided with vertical wall, described clamp body is fixed by the binding nut matched with angle bar upper screwed hole, the clamp body Inner side be provided with groove.The utility model design is simple and easy for installation, is mainly used in the process of cylindrical workpiece. But this fixture needs manpower to step up, and dynamics crosses conference and damages clamped article.
