A welding tool for installing brackets at the rear of an ATV, including a workbench, a front support seat and a rear support seat arranged on the workbench, the front support seat is hinged with a front clamping arm arranged along the length of the workbench, the front clamp The clamping arm is connected with a front drive cylinder that drives the front clamping arm for clamping operation, and the rear support seat is hinged with a rear clamping arm arranged along the width direction of the workbench, and is connected with a drive cylinder for clamping the rear clamping arm. The operating rear drive cylinder, the rear support base is provided with at least one positioning pin on the side close to the front support base.

When welding, place the mounting bracket at the rear of the ATV on the workbench, use the front support seat and rear support seat set at the front and back to support it, and position it with the positioning pin, and then clamp it through the front and rear clamping arms, so that the mounting bracket can be firmly secured. Securely fixed on the welding tooling to facilitate subsequent welding operations.

Further, the front support seat is provided with an inclined support seat on the side close to the rear support seat, and the end of the front clamping arm is provided with two inclined positioning columns, and the inclined support seat corresponds to the two positioning columns. A clamping positioning block with a disk structure at the end is installed at each column position. The structure can ensure reliable positioning of the position of the curved surface in the middle of the mounting bracket at the tail of the beach vehicle, and at the same time facilitates the reliable fixing of the sheet metal parts to be welded to the mounting bracket on the mounting bracket.

Further, a movable positioning block is installed at the end of the positioning column facing the clamping positioning block. This structure enables the positioning column and the clamping positioning block to be clamped and positioned for the welding work, and the movable positioning block at the end of the positioning column has a certain self-leveling function, so that it can fit more closely with the workpiece and ensure stable clamping sex.

In order to further improve the effect of clamping and positioning, the front clamping arm is hinged to the front support seat through a connecting piece, and the front clamping arm is also provided with an intermediate positioning column between the hinge point and the positioning column.

The rear support seat is provided with an extension extending in the direction of the front support seat on both sides of the width direction, and there are two positioning pins in total, which are vertically arranged on the two extension parts respectively, so as to Make sure that the positions of the positioning pins correspond to the corresponding holes on the mounting bracket.

The cylinder barrel of the front drive cylinder is hingedly connected to the front support base, and its piston rod is hinged to the end of the front clamping arm away from the positioning column. With the above structure, the front drive cylinder drives the front clamping arm to clamp in a pivotal manner. Tight operation, reliable clamping, less impact on the cylinder, and improved system stability.

Rollers are installed under the front and rear ends of the workbench to facilitate movement during the production process.

Beneficial effect:

The welding tool for the mounting bracket at the rear of the beach vehicle using the above technical scheme can ensure reliable positioning during welding of the mounting bracket at the rear of the beach vehicle, and has the advantages of compact structure, convenient operation, and high degree of automation.

detailed description

Below in conjunction with embodiment and accompanying drawing, the utility model is further described.

As shown in Figure 1, the welding tooling for mounting brackets at the rear of the ATV includes a workbench 1 with a roughly rectangular plate-like structure, and two symmetrically arranged rollers 5 are installed symmetrically under the front and rear ends of the workbench 1. 1. A front support base 2 is installed at the front of the length direction, and a rear support base 3 is installed at the rear of the workbench 1 accordingly. The front support base 2 and the rear support base 3 are respectively fixed to the workbench by bolts or directly welded to the Workbench 1.

Fig. 2 has shown the specific structure of front support base 2, and a front clamp arm 21 that is arranged along the length direction of workbench 1 is installed on its upper end, and this front clamp arm 21 is hinged to front support base 2 upper end by connector 25— side, the end near the hinge point is connected with a front drive cylinder 22, the cylinder barrel 22a of the front drive cylinder 22 is suspended in the air as a whole, and the upper part is movably connected with the front support base 2, and the piston rod 22b of the front drive cylinder 22 is clamped with the front The ends of the arm 21 are hinged.

One end of the front clamping arm 21 away from the front drive cylinder 22 is symmetrically connected with two positioning posts 23 inclined downwards. The middle positioning column 26 that extends downwards is provided with an oblique support base 4 that is arranged forward and obliquely upwards on the side of the front support base 2 near the rear support base 3. There is a clamping positioning block 41 whose upper end is a disc structure, and the oblique support seat 4 is supported on the front support seat 2 by a support cylinder 42 as a whole, and the height can be adjusted up and down.
