For achieving the above object, the technical solution used in the present invention is: a kind of engineering truck main reducing gear housing assy boring jig, comprise folded seat ring, two cover plates, two gripper shoes and the base plate established up and down, described seat ring is provided with round center hole, the described base plate be positioned at below described centre bore is provided with cutter via hole, and the left and right sides of described centre bore is located at by cover plate described in two.
In technique scheme, described gripper shoe is U-board, and gripper shoe described in two is divided into the both sides, front and back of described cutter via hole, and the two ends of described cover plate are erected in gripper shoe described in two respectively.
In technique scheme, described in two, the inner side edge of cover plate is provided with the segmental arc isometrical with described centre bore.
In technique scheme, cover plate described in each is provided with a fixed via, and described seat ring is provided with two locating holes accordingly.
Preferably, described base plate is square plate, it offers the described cutter via hole of rectangle.
In technique scheme, described seat ring is fixedly connected with described cover plate by 4 M8 screws.
In technique scheme, described base plate is fixedly connected with platen by 4 M20 bolts.
In technique scheme, the end of described cover plate is fixedly connected with described gripper shoe by M12 screw.
Utilize boring of the present invention to process the operation of dead eye, apical pore and centre bore on final drive casing, comprise the steps:
(1) by workpiece with apical pore under, dead eye is located on boring jig at upper form seat;
(2) utilize screw to be located between seat ring and cover plate by the large plane holder of workpiece, realize the location of workpiece;
(3) utilize three hole boring machines thick right boring dead eye, apical pore and centre bore successively, ensure that diaxon bearing bore is relative to apical pore axisymmetrical, centre hole axis system is relative to the offset distance of apical pore axis;
(4) on boring jig, take off the workpiece after processing, complete the boring processing of final drive casing upper bearing aperture, apical pore and centre bore.
Because technique scheme is used, the advantage that the present invention compared with prior art has is:
1. the present invention is the special boring jig of final drive casing, structure is simple, easy to operate, machining accuracy and product qualified rate high.
