Description

Welding tool for upper guide device of axle

Technical Field

The utility model belongs to the technical field of automobile part machining, and particularly relates to a welding tool for an upper guide device of an axle.

Background

When the vehicle is traveling on a rough road or turning rapidly, the compression amount of one side air suspension is easily excessive, and the center of gravity is deviated to roll, so that a stable guide device is required to be mounted on an axle of the vehicle for restraining the roll of the vehicle.

In order to reduce the weight of the guiding device as much as possible, the guiding device integrally formed in the prior art needs to be optimized, and is changed into a stamping part for welding and forming, as shown in fig. 1, the specific structure is as follows: the two opposite sides of the two side arms are connected through two buckled cover plates c to form an H-shaped structure; the two buckled cover plates are internally provided with cavities; the two ends of the side arm are respectively provided with a shaft sleeve b, and the shaft sleeve is welded and fixed with the side arm. Because the upper surface and the lower surface of the upper guide device are all required to be welded, in the welding process of using a welding gun robot, after one surface is welded, the upper guide device is required to be turned over. In the process of turning over the workpiece, the existing welding tool needs to be turned over by means of external forces such as a clamp and the like, so that the fact that all parts of the upper guide device are kept relatively static cannot be guaranteed, and the hidden danger of cracking of a newly welded welding seam exists.

Therefore, providing a new welding tool for a guide device on a multifunctional vehicle axle with a stamping and welding structure is a technical problem that needs to be solved by those skilled in the art.

Disclosure of Invention

The utility model aims to overcome the defect of low welding efficiency in the prior art and provides a welding tool for an upper guide device of an axle.

The utility model provides a welding fixture for an upper guide device of an axle, which comprises two brackets and a supporting plate, wherein the two brackets are symmetrically arranged and are respectively and rotatably connected with the supporting plate;

four corners of the top of the supporting plate are respectively provided with a supporting pin shaft for fixing four shaft sleeves of the upper guide device of the axle, and the upper surface of the supporting plate is also provided with a positioning block for abutting against a cover plate of the upper guide device of the axle.

Further scheme is, the top of support is provided with the arc recess, the backup pad is close to one side of support is provided with the pivot, the one end overlap joint of pivot is in the arc recess.

According to the further scheme, a vertical plate is fixedly arranged between the supporting pin shaft and the supporting plate, one side, close to the support, of the vertical plate is provided with a positioning hole, and a positioning pin is detachably arranged in the positioning hole.

The height of the positioning hole is the same as that of the support.

The further scheme is that one end of the locating pin is clamped with the locating hole, and the other end of the locating pin is overlapped with the top of the support seat, so that the support plate is in a horizontal state.

Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, the upper guide device is placed on the welding tool, the welding station can be adjusted by rotating the support plate, the relative rest of each part of the workpiece can be ensured in the workpiece overturning process, the operation is simple only by overturning the support plate, the cracking of a new welding line can be effectively avoided, and the welding quality is improved. According to the utility model, through the matching of the positioning holes and the positioning pins, the support plate can be ensured to be in a horizontal state during welding, and the quality problem caused by the inclination of the support plate is avoided.
