Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an engine assembling apparatus in an automobile assembly line.

<Prior Art> In a vehicle assembly line, a power unit including an engine and a transaxle is lifted and assembled in an engine room by an engine assembling device. As shown in FIG. 6, the conventional assembling apparatus has an upper surface of a lifter 3 which is moved up and down by a cylinder 4 above a floor surface of a vehicle body 2 which is conveyed by a hanger 1, and which has an axis line in the conveying direction of the vehicle body 2. Is provided with a pilot bar 5 for directing the support base 6 to the pilot bar 5 via a slider 7 so as to be movable, and a receiving piece 8 for supporting the engines 9a and 9b on the support base 6, and a front subframe 11a. , A plurality of receiving pieces 12a and 12b for supporting 11b. By the way, the front subframes 11a, 11b
The receiving pieces 12a and 12b for supporting the power unit must correspond to the type of power unit. That is, the size of the transaxle 10a in the case of the engine 9a and the size of the transaxle 10b in the case of the engine 9b are different, and accordingly,
The support positions of the front sub-frames 11a and 11b fixed to the transaxles 10a and 10b are different in the horizontal direction and the height direction. Therefore, each front sub-frame 11a,
Dedicated receiving pieces 12a and 12b corresponding to the support of 11b were prepared, and they were attached to and detached from the support base 6 according to the type of power unit.

In addition, as shown in FIG. 7, the front sub-frame 11a,
A receiving piece 13 commonly used for any of 11b is provided on a sub-base 16 so as to be movable in the horizontal direction, and a cylinder 14 is used to switch the movement in the horizontal direction, and the sub-base 16 is fixed to the support base 6. There is also a structure in which the cylinder 15 moves up and down to switch.

<Problems to be solved by the invention> In the case of the conventional structure shown in FIG. 6, the receiving pieces 12a and 12b need to be detached and replaced according to the type of power unit.
When various vehicle bodies are transported at random, when assembling the corresponding power unit, the receiving piece 12a,
Removal and replacement of 12b is a considerable burden on the worker,
It is also not efficient. On the other hand, in the case of the conventional structure shown in FIG. 7, switching is automatically performed by the cylinders 14 and 15. However, since the number of cylinders increases, there are problems in weight increase, space, and air piping, and the synchronization of each cylinder There is a problem that is very difficult to adjust.

An object of the present invention is to provide an engine assembling apparatus that solves the above problems of the conventional apparatus.

<Means for Solving the Problems> The characteristic constitution of the present invention for achieving the above object is as follows.
It is installed on the lifter so that it can move back and forth in the transport direction of the car body, and has a support base on which the engine receiving piece is fixed, and is guided on this support base so that it can move back and forth in the same direction as the support base. A pair of left and right first racks, a plurality of second racks that are guided so as to be able to move up and down at an inclination angle with respect to the moving direction of the first racks, and a pinion that interlocks the first rack and the second rack. A cylinder or an operating handle for advancing and retracting the first rack, and a receiving piece for supporting the front sub-frame fixedly mounted on the upper end of the second rack.

<Operation> The present invention moves the first rack forward and backward to move the second rack up and down through the pinion at an angle of inclination, so that the position of the front sub-frame receiving piece is moved vertically and horizontally according to the type of power unit. To switch to.

<Embodiment> An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, 3 is a lifter, and a cylinder 4
Move up and down. Reference numeral 6 denotes a support base, which is provided on the lifter 3 via a pilot bar 5 so as to be movable in the same direction as the conveyance direction of the vehicle body 2. A receiving piece 8 that supports different types of engines 9a and 9b in common is provided on the support base 6, and the configuration up to this point is the same as the conventional one. Reference numeral 10a is a transaxle of the engine 9a, 11a is a front subframe fixed to the transaxle 10a, 10b is a transaxle of the engine 9b, and 11b is a front subframe fixed to the transaxle 10b.

The present invention relates to the front subframe of this different supporting device.
It is characterized in that the switching mechanism of the receiving piece which supports both 11a and 11b in common is improved as follows. The mechanism is second
This will be described with reference to FIGS.

A pair of left and right first racks 17 are provided on the support base 6 so as to be movable back and forth in the horizontal direction which is the same direction as the transport direction of the vehicle body 2. Reference numeral 19 is a block for guiding the first rack 17, which is fixedly mounted on the support base 6. Further, a second rack 20 is guided in the block 19 so as to be movable up and down at an inclination angle with respect to the first rack 17. The second rack 20 is composed of two pairs of right and left, and a receiving piece 21 for supporting the front subframes 11a and 11b is provided at the upper end thereof.

A pinion 22 is provided between the first rack 17 and the second rack 20.
Is rotatably provided on the block 19, and the movement of the first rack 17 is transmitted to the second rack 20 via the pinion 22. Numeral 24 is a stopper for regulating the forward end of the first rack 17.

As an operating means for moving the first rack 17 back and forth, an automatic operating mechanism for connecting the rear ends of the left and right first racks 17 by a horizontal rod 25 and connecting a cylinder 18 to the horizontal rod 25, or a fifth
As shown in the figure, the handle 23 for operating the shifter is replaced with the cylinder 18 and is connected to the horizontal rod 25 to provide a manual operation mechanism.

Since the present invention has the structure as described above, by moving the first rack 17 forward and backward, the second rack 20 is moved up and down along the inclination angle line via the pinion 22. Due to the tilting of the second rack 20, the receiving piece 21 at the upper end thereof has a vertical stroke H.
At the same time, the support position is switched by the horizontal stroke L. The stroke H in the vertical direction is positioned by the receiving piece 21 contacting the upper surface of the block 19, and the stroke L in the horizontal direction is the first rack 17.
Are positioned by the stopper 24. Therefore, by moving the first rack 17 forward and backward with respect to different supporting devices of the front sub-frame 11a of the engine 9a and the front sub-frame 11b of the engine 9b, a plurality of receiving pieces 21 are switched in synchronization. .

<Effects of the Invention> As described above, according to the present invention, a plurality of receiving pieces for supporting the front sub-frame mounted integrally with the engine are moved back and forth horizontally by one cylinder or operation handle. Since the structure is provided on the upper end of the second rack which is interlocked to move up and down at an inclination angle via the first rack and the pinion, and is configured to switch corresponding to the support position of the front subframe that differs depending on the type of engine, the forward and backward drive of the first rack A quick switching operation can be obtained only by operation, various engines can be assembled efficiently, and the structure can be simple and can be provided at low cost.
