Description

Be used to attach together the collapsible multiposition locating dowel pin on the car pallet

Technical field:

The utility model belongs to machinery manufacturing technology field, is a kind of locating dowel pin that is used to attach together on the car pallet.

Background technology:

Attaching together the car pallet is the holder tool that uses on the manufacturing line of assembling motor vehicle, driving engine can be delivered to the vehicle frame place of manufacturing line, assembles.Attach together the car pallet and driving engine need be carried out displacement, and in moving process, keep it stable, the way that solves is that a plurality of locating dowel pins that make progress are housed in the bottom of pallet, locating dowel pin just in time cooperates with the hole of driving engine bottom, locating dowel pin plays the effect of stationary engine at the hole of driving engine bottom in the transportation.Because the car production vehicle is single in the past, pallet only uses at a kind of driving engine, and locating dowel pin is fixed on the tray bottom and gets final product.Present same car production producer may produce a plurality of vehicles, different vehicles is assembling simultaneously on same manufacturing line, different vehicle engine structures are had any different, if still use the pallet of said structure, driving engine that just must one type uses a kind of pallet of structure, and the quantity of production every day different automobile types automobile is unfixing, and pallet needs constantly to adjust, and is time-consuming.

Summary of the invention:

The purpose of this utility model is that a kind of collapsible multiposition locating dowel pin that is used to attach together on the car pallet will be provided, thereby can make pallet be fit to dissimilar driving engines.

The scheme of the utility model technical solution problem is to adopt removable pin, locating sleeve and bearing are configured for attaching together the collapsible multiposition locating dowel pin on the car pallet, have axial chute on the locating bush tube wall, the chute side has two to six cards to slit, removable pin is in locating sleeve, be fixed with control handle on the removable pin, control handle is in card slits, the position is corresponding with chute, bearing is in the locating sleeve bottom, the cross section of bearing is a spill, the locating sleeve bottom is in the groove of bearing, and microscler through hole is arranged at the locating sleeve bottom, and locating sleeve is connected by S. A. with bearing, S. A. passes through hole, spring is arranged at the removable pin bottom in the locating sleeve, and bearing has blind hole, and the opening direction of blind hole is towards the groove of bearing, the top spring is housed in the blind hole, heading is equipped with on the top of top spring, a domatic recess is arranged with heading on the cooresponding locating sleeve outer wall, and the degree of depth of recess from top to bottom gradually from depth to shallow.The bearing of a plurality of collapsible multiposition locating dowel pins is fixedly mounted on attaches together the car tray bottom.According to dissimilar driving engines locating dowel pin is adjusted during use, there is not the locating dowel pin of corresponding aperture position to remove down in driving engine, the method of removing down is that locating sleeve is upwards lifted, because it is microscler that S. A. passes through hole, for upwards lifting, locating sleeve provides the space, in the process that lifts, heading is withdrawed from the domatic recess gradually, locating dowel pin can fall, there is the locating dowel pin of corresponding aperture position to hold up in driving engine, holds up the back heading and under the thrust of top spring, enter domatic recess depths, play the role of positioning, adjust locating dowel pin length according to the driving engine corresponding aperture degree of depth again, method is that control handle is shifted out in slitting from blocking, by sliding tray, in the card that moves into correct position again slits, the control removable pin length of stretching out locating sleeve, the spring of removable pin bottom can guarantee removable pin play up and down not in locating sleeve.

The utility model is simple in structure, and the accuracy of positioning height is fit to multiple vehicle compatibility and extendability, and is easy to adjust, dependable performance.
