Automobile connecting bar major part terminal bolt installation method
Technical field
The present invention relates to automobile connecting bar technical field, more particularly, to a kind of automobile connecting bar major part terminal bolt installation method.
Background technology
The stub end of engine link is the two halves structure coordinated, tight by bolt after coordinating between end cap and con-rod only Solid phase connects.It is that bolt is initially charged with the positioning hole of con-rod only during assembling, matches somebody with somebody for ease of dress bolt of cover with positioning hole interference Close.At present bolt be fitted into the positioning hole of con-rod only it is mostly be by manually tapping installation, it is cumbersome, and be difficult to attach to Position.
The content of the invention
In view of the shortcomings of the prior art, the technical problems to be solved by the invention are to provide a kind of automobile connecting bar major part terminal bolt Installation method, to reach the high purpose of efficiency of assembling.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
The automobile connecting bar major part terminal bolt installation method, comprises the following steps:
(1) operating personnel are by hand by a part in the connecting hole at bolt insertion big end end;
(2) connecting hole at big end end and the bolt avoid holes in support pad are aligned;
(3) hydraulic cylinder works above pad are supported, bolt is pressed into by big end end by the drift on hydraulic cylinder In connecting hole, the up completion bolts assemblies of drift.
Wherein, big end end is placed in the big end end imitation-shaped groove in support pad in the step (2), even Hole position is connect in the imitation-shaped groove of big end end.
In the step (2), the magnet coil being located in support pad is powered.
In the step (2), the end face at big end end is with supporting the table top of pad to fit.
In the step (3) after the completion of bolt press fitting, magnet coil power-off.
The present invention compared with prior art, has advantages below:
The automobile connecting bar major part terminal bolt installation method is reasonable in design, and a big end end is located at into the company in support pad In bar stub end imitation-shaped groove, it is put into bolt Driven by Hydraulic Cylinder pressure head in the connecting hole at big end end and is pressed directly into, bolt peace Dress operation is extremely simple, and production efficiency greatly improved.
Brief description of the drawings
The content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described below:
Fig. 1 is auxiliary implement structural representation of the present invention.
Fig. 2 is present invention support pad structural representation.
Fig. 3 is big end end and bolt cooperation schematic diagram.
In figure:
1. support, 2. frock platens, 3. support pad, 301. bolt avoid holes, 302. big end end imitation-shaped grooves, 4. are stood Post, 5. pressure heads, 6. top plates, 7. hydraulic cylinders.
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 Body stub end corresponds to connecting hole and is provided with the groove for being used for placing bolt head, and cylindrical bar lower end is that microcephaly avoids groove arm.
Hole location is avoided in bolt be provided with big end end imitation-shaped groove 302 in support pad 3.Directly put at big end end Enter in the imitation-shaped groove of big end end, accurately can easily realize that the connecting hole on con-rod only aligns with bolt avoid holes, and Enter bolt to be press-fit into place.Spring is provided with bolt avoid holes in support pad, spring upsprings bolt after the completion of press fitting, is easy to Remove con-rod only.
Magnet coil is provided with support pad, magnet coil, which is powered, when con-rod only positions is easy to con-rod only to be determined Bit manipulation, and con-rod only is not easy to rock during bolt press fitting, ensures press fitting efficiency;Powered off after the completion of press fitting, be easy to the company of removing Bar.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way Limitation, as long as employ the present invention design and technical scheme carry out various unsubstantialities improvement, or it is not improved will The design and technical scheme of the present invention directly applies to other occasions, within protection scope of the present invention.
