Description
Technical field
The utility model relates to automobile engine provision for disengagement, is specifically related to a kind ofly piston to be moved back to the device that unloads out in cylinder.
Background technology
Engine piston is arranged in cylinder, when piston is installed, first by piston pin by piston and the small end of connecting rod composition piston rod part that links together, and then pack near cylinder cap one side from cylinder.The dismounting of engine piston is contrary process, need to firmly piston rod part be exited near cylinder cap one side by cylinder together near bent axle one side from cylinder.
In the disassembling or changing the outfit in process of engine piston connecting rod assembly, due to reasons such as piston ring tensions, piston rod part is difficult to take out, and need to adopt aid.General dismounting mode is now, operating personnel first take off connecting rod cap, re-use T-shaped jacket casing on connecting-rod bolts, firmly piston rod part is ejected to (exert all one's strength by bent axle one side at cylinder, eject by cylinder cap one side from cylinder) from cylinder by cylinder cap one side.But in the process that piston rod part is oppositely firmly ejected, because the impetus of T-shaped sleeve on big end only has a place (T-shaped jacket casing in two connecting-rod bolts at big end place), simultaneously hinged with piston pin between small end of connecting rod and piston, causing moving back connecting rod while unloading at piston rod part can not well locate, connecting rod easily arbitrarily swings and clashing and breaking casing wall around piston pin, even cause in the process of exerting all one's strength T-shaped sleeve from connecting-rod bolts come off (principal risk is that connecting rod swing causes), clashing and breaking piston cooling nozzle, bearing shell and connecting rod etc., and easily cause the serious consequences such as operating personnel are injured.
Summary of the invention
The purpose of this utility model is to provide a kind of piston of automobile engine link assembly to move back handler, this device is positioning piston connecting rod well, solve piston rod part and move back the problem that in the process of unloading, connecting rod arbitrarily swings, avoid clashing and breaking Engine Cylinder Wall, piston cooling nozzle, bearing shell and connecting rod etc., improve the piston rod part security of disassembling or changing the outfit, ensure the intact of operating personnel's safety and parts.
Piston of automobile engine link assembly described in the utility model moves back handler, comprise slide rail and two backstays parallel to each other and vertical with slide rail, the middle part of described slide rail is fixedly connected with afterburning handle, upper end at two backstays is all fixed with slide block, described two slide block sets are contained on described slide rail, lay respectively at the left and right sides of afterburning handle, be all fixed with the guide post stretching out on the lower end surface of two backstays downwards, the diameter of guide post is less than the diameter of bolt hole on big end.
For big end without the situation that carries connecting-rod bolts, moving back while unloading piston rod part, the position of left and right adjusting slide block on slide rail, two backstays are adapted with the position of the connecting rod bolt holes of big end respectively, then the guide post of backstay lower end is put in the connecting rod bolt holes of big end, press afterburning handle and exert all one's strength, thereby piston rod part is ejected near cylinder cap one side by cylinder.
Further, on described slide rail, between afterburning handle and left and right slide block, be all set with spring.The effect that spring is set is to be convenient to suitable adjusting slider position, hinders its position when slide block regulates when too much spring to cushion to slide rail inner side, meanwhile, by the tension force effect of spring, can ensure preferably that reinforcing moves back the stability of connecting rod while unloading.
Further, on described slide block, be provided with slide block locking bolt.If need to move back the piston rod part in each cylinder that unloads same engine, only need to, after moving back for the first time and unloading, tighten slide block locking bolt, by the locking position of slide block, keep the distance between two backstays constant, moving back below unloaded just without the position of adjusting slider again.
There is the situation that carries connecting-rod bolts for big end, further, on described two backstays, all overlap the pilot sleeve that can slide up and down, the diameter of pilot sleeve is greater than the connecting-rod bolts diameter of big end, the stage casing of described backstay and lower end are equipped with sleeve lock shotpin, the barrel of described pilot sleeve is provided with vertically the slideway that the described sleeve lock shotpin of confession that connects passes through, and is provided with the pin-and-hole of connection in this slideway one side.Moving back while unloading piston rod part, first, the position of left and right adjusting slide block on slide rail, adapts respectively two backstays, then with the position of the connecting-rod bolts of big end, rotating pilot sleeve enters in slideway the sleeve lock shotpin in backstay stage casing, thereby put down pilot sleeve, the guide post of backstay lower end is encased, now, again rotate pilot sleeve, the sleeve lock shotpin of backstay lower end is entered in pin-and-hole and locking pilot sleeve prevents that it from sliding up and down; Finally, pilot sleeve is aimed to the connecting-rod bolts of big end, the guide post that is wrapped and the end of connecting-rod bolts are propped up, finally press afterburning handle and exert all one's strength, thereby piston rod part is ejected near cylinder cap one side by cylinder.
The utlity model has following advantage: moving back while unloading piston rod part, this impetus that moves back between handler and big end is two places, connecting rod can arbitrarily not swung around piston pin, the slight swing of connecting rod can be revised by the adjustment that makes force direction, improve to move back and unloaded stability, avoid connecting rod arbitrarily swing and cause the problems such as clashing and breaking casing wall, piston cooling nozzle, bearing shell and connecting rod, improved the security of disassembling or changing the outfit, ensured the intact of operating personnel's safety and parts.
The handler that moves back described in the utility model is owing to adopting slide block to regulate location to two backstays, distance between two backstays can change, the distance changing between two backstays by adjusting slider position is unloaded with the moving back of piston rod part that adapts to different model engine, reaches the object of versatility.
The handler that moves back described in the utility model is owing to being provided with slide block lock pin, in the time of the piston rod part moving back in the each cylinder that unloads same engine, only need to move back for the first time unloaded after the position of lock slider, keep the distance between two backstays, repeatedly moving back below unloaded just without regulating location again, convenient and swift, improve the moving back of piston rod part of engine and unloaded efficiency.
