Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation.
The automobile connecting bar major part terminal bolt installation method, comprises the following steps：Bolt is inserted connecting rod by operating personnel by hand
It is a part of in the connecting hole of stub end；The connecting hole at big end end and the bolt avoid holes in support pad are aligned；Branch
Hydraulic cylinder works above stake pad platform, bolt is pressed into the connecting hole at big end end by the drift on hydraulic cylinder, drift
Up completion bolts assemblies.
Wherein, big end end is placed on when placing connecting rod in the big end end imitation-shaped groove in support pad, even
Hole position is connect in the imitation-shaped groove of big end end；One big end end is placed in the imitation-shaped groove of big end end, connecting hole directly with
Bolt avoid holes are alignd.Or screw rod such as stretches out a part, extension is inserted directly into bolt avoid holes, operation is extremely simple
Just.
The end face at big end end ensures the perpendicularity of connecting rod, ensures press-fit effect with supporting the table top of pad to fit.
During placing connecting rod and bolt press fitting, the magnet coil being located in support pad is powered, positioning action simplicity and bolt
Con-rod only is not easy to rock during press fitting, ensures press fitting efficiency and quality.After the completion of bolt press fitting, magnet coil power-off is easy to remove
Connecting rod.
The installation auxiliary implement utilized as shown in Figure 1 to Figure 3 for the automobile connecting bar major part terminal bolt installation method, including
Support 1, frock platen 2, support pad 3, column 4, pressure head 5, top plate 6 and hydraulic cylinder 7.
Frock platen 2 is arranged on support 1, and the height of frock platen 2 will be adapted to worker to be seated to be operated.Column 4 is
A pair, a column is located on frock platen 2 side by side, and the upper end of column 4 is ledge structure, and top plate 6 is located on ledge structure, is stood
Column top is fixed by nut check.
Hydraulic cylinder 7 fix on the top plate 6, support pad 3 be located on frock platen, hydraulic cylinder 7 positioned at support pad just on
Side.Support pad 3, which is provided with, to be used to avoid the bolt avoid holes 301 for being installed in place bolt, and hydraulic cylinder 7 is upper positioned at support pad
Side, pressure head 5 is located on the piston rod of hydraulic cylinder corresponding with bolt avoid holes 301.
Pressure head 5 is used to bolt being pressed into the connecting hole of con-rod only, and pressure head 5 is cylindrical bar, pressure head and hydraulic cylinder
Piston rod end is connected, and both are connected to be detachable.Pressure head can be changed as needed, adapt to the press fitting of different model bolt.
Bolt avoid holes 301 are one group of different avoid holes of dimensions.The bottom of cylindrical bar is frustum structure, connecting rod
