[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0019] Example 1

[0020] See Figure 1 and Figure 2As shown, the welding fixture involved in this embodiment includes a welding frame 1. A position adjustment shaft 2 with its axis extending horizontally is rotatably connected to the welding frame 1. A position adjustment beam 3 extending along its axial direction is connected in series to the position adjustment shaft 2. Three connecting rods 4 extending horizontally forward and backward are rotatably connected to the position adjustment beam 3. A width adjustment beam 5 is provided on the front and rear sides of the position adjustment beam 3, respectively, and is rotatably connected to all the connecting rods. The width adjustment beam 5 is arranged parallel to the position adjustment beam 3. Each width adjustment beam 5 is provided with a plurality of clamping arms 6 arranged at intervals along its length and extending upward. The clamping arms 6 are provided with clamping components 7 for fixing workpieces. An adjustment wheel 8 is fixedly connected to one of the connecting rods 4 and is rotatably connected to the position adjustment beam. The adjustment wheel 8 is circumferentially distributed with positioning grooves (not shown) with adjacent intervals and equal included angles. A ball-head plunger 9 matching a positioning groove is provided on the position adjustment beam 3. The ball head of the ball-head plunger 9 is embedded in the positioning groove.

[0021] Furthermore, one end of the position adjustment shaft 2 is provided with a directional wheel 10, and the welding frame 1 is provided with a locking assembly 11 for limiting the rotation of the directional wheel. The locking assembly 11 includes a locking block 111, and the locking block 111 has a locking groove 112 for the directional wheel to be inserted and rotate circumferentially inside. The locking block 111 is threaded with a locking screw 113 whose end extends into the locking groove and abuts against the directional wheel. The locking screw 113 is a hand-tightening locking screw.

[0022] Furthermore, the clamping assembly 7 includes a U-shaped open clamp 71, which includes a first screw 711 and a second screw 712. The clamping arm 6 has a first through hole (not shown) for the first screw to pass through and a second through hole (not shown) for the second screw to pass through. The first screw passes through the first through hole and is threaded with a first nut 72. The second screw passes through the second through hole and is threaded with a second nut 73.

[0023] Furthermore, the two width adjustment beams 5 are equidistant from the position adjustment beam 3.

[0024] In this embodiment, the crossbeams on the guardrail are fixed to the width-adjusting crossbeam 5, secured with the open clamp 71 (the nut is not tightened at this time). After all the vertical bars are inserted, the adjusting wheel 8 is rotated, causing each connecting rod 4 to rotate, which moves the width-adjusting crossbeam 5, changing the distance between the two width-adjusting crossbeams 5 until the vertical bar is fully inserted into the side hole on the crossbeam. Then, the nut is tightened for welding. During the welding process, the welding position can be adjusted by rotating the adjusting wheel 10.

[0025] The welding fixture involved in this utility model can change the circumferential position of the clamped product by rotating the directional wheel to facilitate welding by the operator; by rotating the distance adjustment wheel, the distance between the two width adjustment beams can be changed, so that the welding fixture can be used to weld guardrails of different specifications and sizes; and both the directional wheel and the distance adjustment wheel can be used to lock the position and prevent deflection. The overall function is complete and the practicality is strong.
