Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a parallel production type automobile assembly device for assembling multiple types and types of automobiles on one assembly line.

<Conventional technology> Conventional parallel production type automobile assembly equipment, for example,
This is the structure shown in FIG. 5, which was filed in Utility Model Application No. 183852/1983. The configuration of this conventional device is that a movable support 4 that can move and position automobile components toward a means for positioning the same has a plurality of surfaces, and a single unjigged base has a jig 7 fixed to the surface. 6 is supported on the column 5 so as to be rotatable and positionable.

This device receives the required side member WS by the corresponding jig 7 based on the vehicle type signal of the underbody WU, and
The jig base 6 is indexed and rotated to the assembly position relative to the WU to bring the side member WS into an assembled state, and the movable support 4 is moved to the underbody WU side, positioned and assembled, and then joined using an automatic welding machine. .

<Problems to be solved by the invention> In the case of the above conventional device, one jig base 6 is rotatably and positionably supported by the movable support 4.
The width of the base area is large, so there is a problem that the device becomes large and requires a large installation space.

The purpose of the present invention is to reduce the size of the jig base and make the device more compact, thereby solving the above-mentioned conventional problems.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides means for positioning one automobile component carried in, and a movable support that moves and positions toward this positioning means. a jig frame rotatably and positionably supported by the movable support body; a jig having a plurality of fixed or switchable jig members, the jig having a plurality of fixed or switchable jig members; The jig base includes a pair of jig bases that are rotatably and positionably supported, and means for connecting the two vehicle components.

<Function> The present invention described above rotates and positions a pair of jig bases supported by a jig frame to switch to a jig for receiving a required automobile component, and then receives the automobile component by this jig. The assembled posture is achieved by rotationally positioning the jig frame.

<Example> An example of the present invention will be described below with reference to FIGS. 1 to 4. As shown in FIGS. 1 and 2, the outline of the present invention is that a jig frame 11 is rotatably and positionably supported on a movable support 10, and the jig frame 11 has a plurality of surfaces. A pair of jig bases 12a and 12b equipped with jigs 13a and 13b each having a plurality of fixed or switchable jig members on each surface are placed between the rotational axis of the jig frame 11. It is supported so as to be rotatable and positionable around an axis parallel to the axis of rotation.

The details of the configuration of the present invention will be explained with reference to FIGS. 3 and 4.

The movable support body 10 is composed of a slide cart 10a, a slide base 10b, and a jig frame rotation bearing stand 10c, and includes a guide base 14.
It is possible to move and position one automobile component along the upper rail 15 toward the positioning means. Reference numeral 16 denotes a sliding rotary actuator for positioning the movement, and is connected to the sliding carriage 10a via a toggle arm 17. Reference numeral 19 denotes an underbody receiving piece, which is the work positioning means, and is provided on the main base 18.

The jig frame 11 is supported by a jig frame rotary bearing stand 10c, which is a component of the movable support 10, so as to be rotatable by a rotary shaft 20 and positionable by a jig frame positioning stopper 25. There is. 22 is a rotary actuator for rotating the jig frame.

The pair of jig bases 12a, 12b have a plurality of rectangular base surfaces, for example, and are equipped with jigs 13a, 13b having a plurality of fixed or switchable jig members on each of the surfaces, and the jig frame 11, there is a support shaft 2 across the axis of the rotating shaft 20.
It is rotatably and positionably supported by 1a and 21b. 24a and 24b are rotary actuators for the jig base; 23a and 23b are rotary actuators for the jig base;
is a jig-based positioning stopper.

Next, the operation of the device of the present invention will be explained.
The movable support 10 is at position A in FIG. 3, and the jig frame 11 is rotated in a horizontal position. Jig base positioning stopper 23a,
23b is released, the jig bases 12a and 12b are rotated by the rotary actuators 24a and 24b for rotating the jig base, and after locating the surface with the jigs 13a and 13b corresponding to the vehicle type, the jig bases are rotated. It is positioned and fixed using positioning stoppers 23a and 23b.

Next, the side member W is transferred to the third
The jig 13a is lowered from the B position to the A position in the figure.
13b. By this reception confirmation signal of the side member W, the side member W is fixed by the jigs 13a and 13b. After that, the jig frame positioning stopper 25 is released, and the jig frame 11 is rotated counterclockwise in FIG. 3 by the jig frame rotation rotary actuator 22.
Rotate 90 degrees and position the jig frame stopper 25
The position is fixed.

On the other hand, the underbody is transported from the previous process by a transfer and set in the underbody receiving piece 19, and when this is confirmed, the movable support 10 is moved from position A in FIG. 3 by the sliding rotary actuator 16. Move to position C. As a result, the side members W fixed to the jigs 13a and 13b are combined with the underbody set in the underbody receiving piece 19, and the assembly is performed using an automatic welding machine or the like as a connecting means (not shown). be.

After that, the jigs 13a and 13b are unfixed, the movable support 10 is returned to the A position, and the jig frame 11
The machine is then turned 90 degrees and held in a horizontal position again, and the next assembly is repeated.

<Effects of the invention> As described above, the assembly device according to the invention for parallel production of multiple types of vehicles has a jig frame that is rotatably and positionably supported by a movable support and has a plurality of surfaces. A pair of jig bases each having a jig on each surface are supported so as to be rotatable and positionable about an axis parallel to the rotation axis of the jig frame, with the rotation axis of the jig frame in between. Because of this structure, the surface width of the jig base is reduced, which reduces the weight of the jig base and reduces the index rotation operating force.The device can be made more compact, and the installation space can be reduced. It has the effect of
