Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
As shown in Figure 1, electric control oil injector of diesel engine assembling and disassembling stand described in the utility model, comprises the parts such as base 1, column 2, overturn platform 4, traveller 5, assistance platform 6, pressing device platform 7.
Base 1 is rectangular flange, is fixed by 4 bolts and workbench.Base 1 and column 2 are welded as a whole, and column 2 top is welded with axle sleeve 3, coordinates with the rotating shaft of overturn platform 4.Axle sleeve has clamping screw 10, rotating shaft has location dimples 9, overturn platform can rotate to 0 °, 90 °, 180 °, 270 ° and locking location.Overturn platform 4 is equipped with two relative grip slides 11, slide block can move under the promotion of reverse-flighted screw 14 along its guide rail simultaneously in opposite directions.Two grip slide 11 cooperatings can be clamped in the parallel plane place on the nozzle holder face of cylinder, and adjustment fuel injector present position, left and right, make on its axis being in overturn platform 4.Grip slide 11 maximum grip size is comparatively large, and the thickness of slide block is moderate, can be applicable to the specification of most of electric control oil injector of diesel engine.Traveller 5 is vertical with overturn platform 4 to be fixed, and can rotate together with overturn platform 4.Traveller 5 side has apart from uniform multiple location dimples 9, locates on traveller for assistance platform 6 and pressing device 7.Assistance platform 6 is processed with the hole with traveller matched in clearance, coordinates with traveller 5 and it can be made to be free to slide along traveller axis.Assistance platform 6 is equipped with clamping screw and handwheel 10, can be positioned at any pit of traveller as required.Assistance platform 6 is equipped with grip slide structure, two slide blocks are promoted respectively by screw rod 13, and the working face of slide block has V-type groove, are convenient to the face of cylinder clamping nozzle holder.After the top of fuel injector is fixed by overturn platform 4, the position height of adjustment assistance platform 6 locking, then adjust the face of cylinder that V-type groove grip slide 12 makes it to clamp nozzle holder.Pressing device platform 7 passing hole coordinates with traveller 5, can slide on traveller and locate.Pressing device there is screw thread hold down gag 8 for the dismounting of fuel injector partial valve needle.
