Abstract

PURPOSE:To simplify welding of a side panel, etc. without decreasing working efficiency, by moving a welding jig into between a welding position and a setting position, binding and welding members on the outside in the setting position and providing means for conveying said members. CONSTITUTION:A welding jig 4 is provided to a welding body in such a way that the jig is turned over in an inward position and an outward position and is moved to a welding position A and a setting position B. A jig base 6 is provided on the outside of the position B and an outer member and an inner member constituting a side panel W3 are set thereto. The outer member and inner members are bonded and welded by means of a welding member 7 provided to the base 6 and are thus worked to a side panel W3 of one body. The jig 4 is turned over in the outward position in the position B and the panel W3 is clamped by a conveyance arm 8 provided to the base 6, then the panel is transferred to the welding jig 4. The side panel W3 is bonded and welded on the base 6 while the jig 4 moves to the position A and welds the other parts.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile body welding device for assembling and welding an automobile body twine to other members of the automobile body such as a floor and a roof.

Conventionally, as shown in FIG.
A welding device main body (b) disposed on the side of the welding station (a) has a welding jig (e
) with a pipe, set the welding jig (C) of the automobile body at the set position, and set the welding jig (r) to the set position. The floor (e
) is known (Japanese Patent Publication No. 53-21542), but in this case, the side panel (d) is assembled and welded in advance by welding the outer and inner members that make up the side panel (d). It is processed into a one-piece panel, and in this state it is suspended from the nozzle (f) and welding station (a).
), and by tilting the welding jig (c) to the setting position, the welding jig (c) is carried in and set from above. According to this, the size of the hanger (f) etc. )11
of? The conveyance mechanism of the channel (d) has become very different,
This is accompanied by the inconvenience of increased line space and equipment costs.

It is an object of the present invention to provide a device that eliminates such inconveniences, and the main body of the welding device is arranged on the side of a welding station, and has an inner welding position facing the station and an outer set position. Move between! 671 A movable welding jig is provided, and a site nominal of an automobile body is set in the welding jig at the set position, and the welding jig is moved to the welding position to carry the floor etc. to the station. In a device that is assembled and welded to other parts of an automobile body, the welding jig tl - the welding position and the setting position are moved inverted between an inward position and an outward position, and the A jig stand for setting the outer member and inch member constituting the side panel is provided outside the setting position, and these parts I are connected and welded to the jig stand, and the site nominall is moved from the t1 jiji A stand. It is characterized by comprising a swingable blood vessel arm that transports the device to the set position.

Next, the present invention will be explained with reference to the illustrated embodiments.

The drawings are shown in the 71st flash and show an example in which the side panels (Wl) are assembled and welded to the floor (W+l) and roof (prefecture) of the automobile body, and Figs. As shown in Figure 3, the welding equipment bodies (3) are placed on both sides of the welding station (2) where the floor (W+) and roof (W2) are connected to the trolley (1). , a movable welding jig f41 is provided on the main body (3) between the inner welding part !i:A facing the station (2) and the outer set positions 1 to B. The lead panel CXV3)''lr which is L-tightened by the jig (4) at the set position B, and the floor (W,) carried into the station (2) by the movement of the jig (4) to the welding position A. The floor (W+) and the K
It was welded to the GL roof (W2).

Although the above is not particularly different from the conventional type described above, there are improvements to the present invention! The i-type molten welding A (4) is reversed and moved between the total welding position cylinder A and the set position (Xtn) to an inward posture and an outward posture, and is further moved to the set position B.
The outer member (■・1a) and the inch member (W3
b)) and a jig stand ((U1) is provided, and the jig stand (6) is connected to these members 0 as shown in Figs. 4 and 845). 'C integrated site nominal (~6 contact member to be processed into Xil (7)
), and the site nogunnel (1w' + full-length jig stand (6
) to the set position trqB.

To explain this in more detail, the main body of the welding device +3) +=yo, the movable base (11) that is guided by the guy 19 (9) and moved forward and backward by the cylinder 01, and the movable base ( A pair of pillars 02 (1) erected on the mark and a frame (1) supported 9H between the pillars (1H21) and reversed by a reversing cylinder 0ki shall form G4 and 7L, The welding jig (4) is attached to the front surface of the frame 04, and thus the M
The fixture (4) is moved between the welding parts M, A and the set position B by reversing the mount a4 and moving the movable base aD back and forth between the inward and outward positions. I made it.

It should be noted that the welding jig (4) f, which is made to move in reverse in this way, was originally proposed by the applicant of the present application, for example, in Japanese Patent Application No. 55-7078.
Although it is proposed in No. 7 etc., the same jig (4)
In addition to the above-mentioned welding member (5), a welding member for side panel processing is provided, and the side panel (
Ws), and according to this, the set position B
It takes time to set the constituent members (Ws a) (vJsb) of the side panel (opening) to the jig (4) and the subsequent machining pressure of the site nominal (Ws), and the welded parts M, A [in the The loss time from the completion of a welding operation to the start of the next welding operation becomes long, and in contrast, as in the present invention, the processed side panel (processed by the welding member (7) on the jig stand (6)) :'+Vs) is set in the jig (4), the loss time can be shortened.In this case, by reversing the Mosquito Control A (4) We set position fd, to the outward facing position at B, the conventional method described above can be Lost time can be shortened by setting the site nominal (coin) on the jig (4), and in this case, by inverting the jig (4) to the outward position at the setting position B, the conventional method described above can be Instead of carrying in the side panel (Ws) from above, the site nominal (Ws) is transferred and set on the jig (4) from the outside using the transfer arm (8) on the jig table (6). However, the transport mechanism is significantly simplified.

Here, the transfer arm (8) is attached to a pair of rotating pars (15) provided on the jig table (6) K, and is attached to the arm (8) as shown in #-i, No. 64. Site?Nel (X~

According to the operation of the drive device (17) connected to the skeleton rotation r-(+51), the arm (8) moves from the side panel (hair to
In the illustrated case, the rotating part 09 and the drive device a7) are moved to the set positions E, BK and the welded part A.
The jig (4) of the arm (8) is supported by a movable frame OI that moves forward and backward with cylinder 0 sand in a direction perpendicular to the plane of (4).
The movable frame O1 is moved by swinging to a predetermined position opposite to the arm (8) and the side panel (Ws) on the arm (8) is moved in parallel toward the jig (4). is delivered to the welding jig (4).

In the drawing, (a) shows the positioning bins on the jig stand (6) that match the retaining holes (9) of each inch member (%b) of the side tunnel (Ws), (2+1' (21 is the welding jig) (4)

As described above, according to the present invention, I is a transfer arm that inverts and moves the welding jig to the set position with an outward posture, and equips the jig stand with the pre-processed site nominal on the jig stand outside of the welding jig. The mechanism of conveying the side and e-nels is greatly simplified compared to the conventional type mentioned above, reducing work efficiency. This has the effect of eliminating the above-mentioned disadvantages of the conventional type without causing any problems.
