Description
Technical field
The utility model relates to a kind of automobile assembling servicing unit, and more particularly, it relates to a kind of piston assembling that is used to install the automobile engine cylinder piston rod part and draws the cover assembly.
Background technology
When assembling the piston rod part of automobile engine cylinder, generally all to use and draw cover, draw to overlap to play and locate and guiding function, earlier piston rod part is placed in drawing the cover assembly during assembling, stretch into to draw to overlap to push with sticking plaster again and put in place.But draw cover in the existing assembly technology and all be single use; And in an automobile engine a plurality of cylinders arranged side by side are arranged all generally; Just can only carry out one by one several times with the single cover that draws repeatedly when piston rod part is installed, efficiency of assembling is lower like this, is unfavorable for immediately following productive temp.And the single cover that draws does not have positioner; From a cylinder, take out the change that tends to when putting into next cylinder because of body position and power thrusts at every turn and cause drawing cover position deflection; Thereby receive jam, and can not one-time-reach-place, this has just further influenced efficiency of assembling.Notification number is that the utility model of CN201183244Y discloses a kind of oil cylinder piston ring assembling servicing unit on January 21st, 2009; Be arranged between piston and the cylinder tube; Described servicing unit is provided with the guide surface and excessive hole of taper, and described guide surface guiding piston is inserted cylinder tube.When the piston ring on the piston at the guiding face cone of servicing unit under the effect of extruding, draw in gradually, slip into one section the excessive hole identical then with the cylinder tube internal diameter, under the guiding in excessive hole, the piston that is with piston ring is easily packed in the cylinder tube.Because there has been this servicing unit to improve efficiency of assembling, reduce labor intensity, the generation of injury suffered on the job accident has characteristics easy for installation, easy-operating, is particularly useful for the quick assembling of more large batch of piston, piston ring and cylinder tube.But this oil cylinder piston ring assembling servicing unit also is with monomeric form work, once can only carry out the assembly work of a piston ring, if be used for a plurality of oil cylinders parts arranged side by side, can seem that still efficient is not high.
The utility model content
Once can only act on a manipulating object in order to overcome the existing cover that draws, the defective that operating efficiency is lower, the utility model provides a kind of can carry out a plurality of cylinder piston link assemblies installations simultaneously, and the cover assembly is drawn in the piston of significantly increasing work efficiency assembling.
The technical scheme of the utility model is: the cover assembly is drawn in a kind of piston assembling; Comprise base plate; Be installed with on the base plate some draw cover, with draw the corresponding through hole in cover position and draw and overlap the assembly positioner; The lumen pore that draws cover is communicated with said through hole, and the position of each cylinder on the position of drawing cover and the engine cylinder block is corresponding.This piston assembling draw the cover assembly integrated a plurality of covers that draw; When being used for to the engine cylinder block formed by a plurality of cylinders assembling cylinder piston link assembly; It is corresponding one by one with each cylinder respectively to draw cover; A plurality of cylinder piston link assemblies can put together together to be installed, and takes out and draws cover another is installed and need not to install one.Through described positioner, this piston assembling is drawn can both keep same and relative position engine cylinder block when the cover assembly uses at every turn, and respectively draws cover and can both keep and the accurate contraposition of each cylinder.Therefore, use the assembling of this piston to draw the cover assembly and can improve the efficiency of assembling of cylinder piston link assembly on engine cylinder block greatly.
As preferably, draw cover assembly positioner and comprise two alignment pins, said alignment pin is fixedly arranged on the bottom of base plate.Locating hole is set on the engine cylinder block, and the corresponding hole site aligned fit on alignment pin and the engine cylinder block can be drawn the cover assembly with the assembling of this piston and accurately located.For the such plate object of base plate, two alignment pins can be located completely, and are simple in structure with the alignment pin location, save space and easy to use.
As preferably, said alignment pin is respectively cylinder alignment pin and chamfered edge alignment pin, and cylinder alignment pin and chamfered edge alignment pin are fixedly arranged on the two ends of base plate respectively.Adopt cylinder alignment pin and two kinds of difform alignment pins of chamfered edge alignment pin, the position that can intuitively distinguish base plate quickly towards, guarantee originally to draw cover assembly positioner and all use at every turn with same disposing way, improve the uniformity of assembling effect, the minimizing error.
As preferably, the two ends of base plate are installed with handgrip.Handgrip is convenient to draw holding and moving of cover assembly positioner.
As preferably, the lumen pore that draws cover has tapering, and said lumen pore internal diameter is from top to bottom received little gradually.Tapering has guide effect, like this cylinder piston link assembly put into draw when cover can be very accurate, along with the propelling gradually of cylinder piston link assembly, drawing the guiding of overlapping lumen pore and can finally adjust in place voluntarily through the band tapering.
The beneficial effect of the utility model is:
Improve the efficient of cylinder piston link assembly assembling.The utility model integrates a plurality of covers that draw, and can carry out the piston rod part assembling work to a plurality of cylinders simultaneously, compares with the single cover that draws, and efficient obviously improves.
Improve the alignment precision that draws cover and cylinder, be convenient to smooth use.Positioner on the utility model can guarantee respectively to draw cover and the contraposition fast and accurately of each cylinder, the carrying out of operation convenient for assembly.
