Description

Method and apparatus for connecting vehicle body and power plant

The present invention relates to a method and equipment for coupling a car body and a power plant in an automobile.

As shown in FIG. 12, conventionally, when mounting a power plant P on which a power drive system such as an engine and accessories and the like are previously assembled on a sub frame F (see FIG. 10) to a side frame S on the vehicle body side With respect to the vehicle body W suspended and moved in the hollow by the transport hanger H of the conveyor C / V, the carriage 100 on which the power plant P is mounted from below is pulled up by the lifting device 101 in the vehicle body direction. Then, as shown in FIG. 6, FIG. 8 and FIG. 9, the stud bolts ST implanted on the power plant P side are mounted in the mounting holes BR1 of the left and right brackets BR previously disposed on the vehicle side frame S. Insert it. In this state, a worker fastens sub frame F (FIG. 10) to vehicle body W from below with bolt B1 (FIG. 10), and further tightens nut N to stud bolt ST to connect vehicle body W and power plant P Is going.

In the joining operation, the hanger H on which the vehicle body W is placed and the carriage 100 on which the power plant P is placed as shown in FIG. 12 so that the mounting holes BR1 of the bracket BR and the axis of the stud bolt ST coincide with each other. The position of the vehicle W on the hanger H at the time of transportation, the position of the power plant P on the carriage 100, or the manufacturing error of the vehicle W or the power plant P, as shown in FIG. Misalignment may occur between the mounting hole BR1 of the bracket BR and the axial center of the stud bolt ST shown in FIG. If it is attempted to couple the vehicle body W and the power plant P in a state in which this axial misalignment occurs, so-called galling occurs between the stud bolt ST and the mounting hole BR1, and the stud bolt ST is used in the mounting hole BR1. It becomes difficult to insert the sub-frame F up to the end, and there is a disadvantage that the sub-frame F can not be fastened to the vehicle body W via the mounting hole F1 of the sub-frame F by the bolt B1.

For this reason, conventionally, the worker grasps the positional relationship between the mounting hole BR1 and the stud bolt ST from the lower side of the vehicle body, and makes the vehicle 100 on the hanger H or the power plant P on the vehicle 100 swing by hand. The operation mode is adopted in which the galling is eliminated and the stud bolt ST is inserted into the mounting hole BR1 up to its base end and fastened by the nut N. However, since this operation mode is an operation while looking up the positions of the mounting hole BR1 and the stud bolt ST from below, the operator is forced to have a difficult posture. Further, since the stud bolt ST is laid out on the upper side of the power plant P, the power plant P obstructs the field of vision when looking up from below, making it extremely difficult to visually identify the location where the galling occurs. In some cases, it may be possible to cause galling several times.

In order to address this problem, in Patent Document 1, the screw portion of the stud bolt is constituted by the main screw portion and the small diameter screw portion on the tip end, and the small diameter screw portion is formed into a trapezoidal screw shape. A technique has been disclosed that makes it possible to make the contact with the mounting hole a contact at an obtuse angle, suppress biting due to plastic deformation, and prevent galling.

Further, Patent Document 2 discloses a technique in which a single engine is lifted and moved by a lifting means such as a chain, and lowered to a predetermined position in an engine room of a vehicle body for assembly. When mounting the engine, while lowering the engine on the vehicle body side frame, insert stud bolts pre-planted on the vehicle body side into the bolt holes of the brackets protruding on the left and right sides of the engine body, and tighten the engine with the nuts. It is connected to the car body. And, in order to improve the efficiency of work, when using the stud bolts with different lengths and lowering the lifted engine in the mounted state, insert the longer stud bolt into the bolt hole of the bracket first The attitude of the engine is displaced so that the shorter stud bolt can be smoothly inserted into the bolt hole.

However, even with the technique of Patent Document 1, when the positional deviation is large, galling still occurs, and the problem of the worker's difficult posture of working while looking up from below also remains.

Also in the technique of Patent Document 2, the problem of galling due to positional deviation is not solved, and in order to solve this, it is necessary for the operator to rock the engine, which is a time-consuming operation. Further, the mounting method described in Patent Document 2 is a technology that can be adopted only when mounting a single engine, and for the purpose of improving the working posture, reducing the number of man-hours and shortening the vehicle assembly line length, It can not be adopted in the case where a power plant in which accessories and the like are assembled in advance on a sub-frame in a small assembly line is mounted on a side frame of a vehicle body.

Further, in the prior art described with reference to FIGS. 6 to 12, the form of the fastening operation of the nut N to the stud bolt ST is performed after temporarily fastening the sub frame F to the vehicle body W via the mounting hole F1 by the bolt B1. As shown in FIG. 12, the worker climbs on the work bench D and performs the main fastening, and the work at a high place is accompanied, and the scaffolding is easily limited. The reason why the bolt B1 is not completely fastened from the beginning is that each nut N can not be tightened with an accurate torque unless the nut N is fastened to each stud bolt ST in a state where the vehicle body W and the power plant P face each other. If each nut N can not be tightened with an accurate torque, a deviation occurs in the drive system, which may cause abnormal vibration or abnormal noise. Therefore, conventionally, in order to make the vehicle body W and the power plant P face each other, the pressing device 102 is required to press the power plant P from the lower side so that 9.8 m / s ² is applied to the vehicle body W. There is a problem of being prone to Furthermore, since it is necessary to fully fasten the temporarily fastened bolt B1 after the nut N is fastened to the stud bolt ST, there is also a problem that the number of assembling steps increases.
