Makethejigup

一.Makecharacteristicandapplicationofthejigup

Itisthatonesetmakesallkindsofgooduses,differentforms,differentspecificationsizetomakethejigupinadvance,thestandardcomponentwithcompleteinterchangeabilityandhighwearabilitywasassembledwithshuttingone.Requireelectvariousstandardcomponents,canassembleintojigssuchasmachining,examiningandassembling,etc.accordingtotheprocessingofvariousparts,inordertoreplaceaseriesofspecial-purposejigs.Afterfinishingusingeachtime,canbreak,washandkeepthecomponent,waittoassembletheusingofthenewjignexttime.Makethecharacteristicofthejigup:

Thestructureisflexibleandchangeable;thecomponentcanbereusedforalongtime;Designandassemblecycleshort.

Makethejigupandcomparewithgenerallyspecial-purposejig,obviouslyhavethefollowingadvantages:

1.Shortenanddesignandmakethecycleofthejig,reduceorremitthestrenuousjigdesignandmanufactureprocessgreatly.Designandmakethespecial-purposejigofasetofmedium-sizedcomplexity,ittakesthree,fourdays;Andisassembledthejigbythestandardcomponent,islessthaneighthoursonaverage,canshortenmorethan90time.

2.Hasreducedtheconsumptionofmakingthenecessarymaterialofjig.Makethespecial-purposejigofasetofmedium-sizedcomplexity,need10to30kilogramsofmetalmaterials;Andmakingthecomponentofthejigupcanberecycled,useandonlywearandtearandconsume0.3to1kilogrameachtime,cansavemorethan95materials.

3.Havereducetheamountoflaborofmakingthejig,hasreducedthecostofjig.Oneequipmentworkercanassemble1to2standardsetsofassociationjigeveryday,canassemble45to60setsofstandardsandonesetofassociationsjiginonemonth,isequivalenttothemonthlyoutputofasmall-scalejigworkshop,use,makejigupextensively,canreducebecausetoolworkshopmakespecial-purposejignecessaryamountoflabor,toolconsumeandnecessaryapparatus,canlowercosts80.

5.Flexibleandchangeable.Have20,000associationjigofcomponentassembleworkshop,canassemblemorethan400ofjigallkindsofeverymonth,special-purposejigthiscanonlysuitableforonelinesofprocessofproduct,canchangesizeandperformanceofstructuremuchmoreflexible.

Becauseofhavedescribedaboveadvantage,makeupjigsuitableforsinglepiecesofsmallserialproduction,trialproductionofnewproductsandfinishtheassaultingproductiontasktemporarilyespecially.

But,maketheshortcomingthatthejighasittooup:

1.Becausecomponentprecisionrelativelyhigh,sevengenerally,need,usealloysteelproductsmaterial,sothecomponentmanufacturingprocessiscomplicated;theremustbealargenumberofcomponentsatthesametimetostore.Therefore,purchasingforthefirsttimeormanufacturingexpenseismuchhigherthanthespecial-purposejig.

2.Becausethestoragelevelisrelativelybig,managementofthecomponent,maintenanceworkshouldspendthelargeramountoflabor.

3.Becauseofmakeupjigtoassemble,comparewithspecial-purposejigbymanypiecesofassociation,itisworsewithrigiditytobemaybemorecumbersome.

Shortcomingdescribedaboveisrelative,andcanovercometoo.Forexample:
