The technical scheme of the utility model is realized like this: the utility model provides a differential mechanism casing rapid Assembly device, includes the base plate, its characterized in that: the angle locating plate is installed to the both sides of base plate, open at the middle part has the location fastening round hole, the fixed plate is installed to the lower part, the fixed plate on install longitudinal positioning device, the angle locating plate on open and to have the locating hole, the locating hole in install the location uide bushing, the location uide bushing in install the guide post, the guide post insert in the cross hole of differential mechanism shell, carry out horizontal angle location to the casing.
Longitudinal positioning device be equipped with the wind big gun rifle, the wind big gun rifle install on the fixed plate, its position corresponds and is located location fastening round hole department down, wind big gun rifle upper portion install extension sleeve, extension sleeve top be located location fastening round hole, extension sleeve top inside weld have a tensioning nut, tensioning nut internal thread even install vertical tensioning screw, vertical tensioning screw pass differential mechanism inferior valve, fasten the assembly through extension sleeve with differential mechanism inferior valve.
And a positioning groove for positioning the lower differential case is formed at the positioning fastening round hole in the middle of the base plate.
And a tail end pulling piece is arranged at the top of the longitudinal tensioning screw rod to limit and fasten the upper and lower shells of the differential mechanism.
When in use: the differential mechanism lower shell is placed in the positioning groove, the differential mechanism upper shell is placed on the differential mechanism lower shell, the guide posts on two sides of the base plate are inserted into the cross holes of the differential mechanism shell, the transverse angle of the base plate is positioned, the longitudinal tensioning screw rod penetrates through the differential mechanism upper shell and the differential mechanism lower shell from top to bottom and is inserted into the tensioning nut, the air gun is started at the moment to drive the lengthening sleeve to rotate, the longitudinal tensioning screw rod is connected and moves downwards, the differential mechanism upper shell and the differential mechanism lower shell are fastened and assembled through the tail end pull piece, and the differential mechanism shell has certain clamping force on the longitudinal tensioning screw rod, so that the longitudinal tensioning screw rod cannot rotate simultaneously along with the lengthening sleeve after the air gun is started.
After the assembly is completed, the longitudinal tensioning screw rod can be taken out only by starting the air cannon gun to rotate in the opposite direction, and then the differential shell is taken out.
The utility model has the advantages that: such quick assembly device of differential mechanism casing has that the assembly rate is fast, and the assembly precision is high, convenient to use, efficient, advantage that workman intensity of labour is low.
