Description

Body tailgate welding tooling

technical field

The invention relates to the technical field of automobile manufacturing, in particular to a welding tool for the tailgate of a vehicle body.

Background technique

In the production process of automobile body-in-white, many parts such as the tailgate of the car body need to go through the welding process. The welding of the tailgate of the car body in the prior art requires multiple cylinders to clamp, so there is a problem during the welding operation. The following problems: 1. The cylinder cannot be turned over at will to an angle suitable for welding, which is inconvenient to operate, resulting in low work efficiency; 2. It takes up a lot of space and costs high.

Contents of the invention

The technical problem to be solved by the present invention is to provide a tailgate welding tool for a car body, which can solve the problems of difficulty in turning over the cylinder, inconvenient operation and high cost in the welding of the tailgate of a car body in the prior art.

In order to solve the above-mentioned problems, the technical solution adopted in the present invention is: the tailgate welding tool of this car body includes at least two support rods that pass through the slide block at its lower end and stand in the chute of the base. The bases have the same length and direction; the upper ends of the support rods protrude relatively to have work clamps, and the work clamps are all slidably connected to the support rods through work clamp locking screws.

In the above technical solution, a more specific technical solution may also be: the workpiece clamp includes a sliding bar and a movable sleeve that is set on the sliding bar through a movable sleeve locking screw and is fixedly connected with the collet, and the collet Workpiece pressing screws are installed on the top, and a chute for the slide bar to slide is opened on the support bar.

Further: one side of the base is provided with a through hole for the locking screw of the wearing support rod and in the same length direction as the base.

Owing to adopting above-mentioned technical scheme, the present invention has following beneficial effect compared with prior art:

1. Since there is a chute on the base, there are support rods standing opposite to each other in the chute, and the upper ends of the support rods protrude relatively to have workpiece clamps, and the movable sleeve of the workpiece clamp is set on the slide rod and fixedly connected with the chuck; working At the same time, the two workpiece clamps are respectively clamped to the rear fender of the car body, and the unwelded parts are closed through the chute, and the movable sleeve is rotated to a suitable angle position for welding. The welding is safe and convenient, and the work efficiency is high.

2. Since the support bar is provided with a chute for the slide bar to slide, the upper and lower positions of the workpiece clamp can be adjusted.

3. Since one side of the base is provided with a through hole for wearing a support rod locking screw and having the same length direction as the base, the two support rods can be locked.

Description of drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

FIG. 2 is a top view of FIG. 1 .

Detailed ways

The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

The tailgate welding tool for the car body shown in Fig. 1 and Fig. 2 includes a base 3 on which two support rods 1 stand opposite each other, and the upper end surface of the base 3 is provided with a chute 5 having the same length direction as the base 3 The lower ends of the two support rods 1 all have sliders, which are installed in the chute 5 and are slidably connected with the base 3; The rod 21 and the movable sleeve 22 which is set on the slide rod 21 and fixedly connected with the chuck 25 through the locking screw 23 of the movable sleeve, the chuck 25 is equipped with the workpiece compression screw 24, and the supporting rod 1 is provided with a workpiece holder. The locking screw 11 is a chute for sliding connection with the workpiece holder 2; one side of the base 3 is provided with a through hole 4 through which the supporting rod locking screw 31 is worn and the length direction of the base 3 is the same.

The operation steps are as follows:

a. Clamp the parts of the tailgate of the car body to be welded into the chuck 25 of the work clamp 2 respectively;

b. Loosen the support rod locking screws 31 respectively, adjust the distance between the support rods 1, make the welding parts of the tailgate of the car body to be welded close up, and respectively tighten the support rod locking screws 31 for positioning;

c. Loosen the movable sleeve locking screw 23 and the workpiece pressing screw 24 respectively, so that the welding position on the end face of the rear fender of the car body to be welded is flush, and adjust to a suitable welding position, and tighten the movable sleeve respectively. Screw 23 and workpiece hold-down screw 24 are positioned;

d. Use a welding machine to automatically weld one end face;

e. Loosen the movable sleeve locking screws 23 respectively, rotate the collet 25 180 degrees at the same time, tighten the movable sleeve locking screws 23 for positioning;

f. Use a welding machine to automatically weld the other end face, that is to say.
