The welding key point of the connecting frame 600 is that the welding position of the two side plates 620 on the bottom plate 610 needs to be ensured to be accurate, meanwhile, the two side plates 620 also need to be aligned in parallel, the two first connecting holes 640 of the two side plates 620 need to be ensured to be coaxial, and the two second connecting holes 650 of the two side plates 620 also need to be ensured to be coaxial, so that the accurate position fixing needs to be performed on the side plates 620 and the bottom plate 610 when the connecting frame 600 is welded, and better welding quality can be obtained. At present, the welding of the connecting frame 600 is mainly performed through a simple tool, so that accurate positioning of the side plate 620 is difficult to realize, the manufacturing efficiency of the connecting frame 600 is low, the welding time is long, the welding precision is difficult to ensure, and the manufacturing cost is seriously increased. The positioning tool special for the connecting frame 600 can greatly improve the positioning accuracy of the side plate 620, the bottom plate 610 and the connecting seat 630, so that the welding quality and the welding efficiency of the connecting frame 600 are improved, and the production cost of the connecting frame 600 is reduced. The positioning tool of the present embodiment is described in detail below with reference to fig. 1 to 5.

In some embodiments of the present utility model, the positioning fixture includes a base 100 and a first positioning structure 110 and a limiting seat 200 mounted on the base 100, the base 100 is rectangular, the upper surface of the base 100 is provided with a supporting surface protruding from the surface thereof, the supporting surface is provided with a supporting block, a bottom plate 610 is placed on the supporting block, a side plate 620 is placed on the supporting surface, the first positioning structure 110 is mounted on the supporting surface, and the limiting seat 200 is mounted on the upper surface of the base 100. Referring to fig. 1 and 2, two first positioning structures 110 are provided, the two first positioning structures 110 are disposed at intervals along the width direction of the base 100, and the two first positioning structures 110 are disposed between the two side plates 620.

Referring to fig. 1 and 2, opposite sides of the single side plate 620 are respectively abutted against the first positioning structure 110 and the limiting seat 200, and then one end of the side plate 620 in the length direction is contacted with the second positioning structure 120, and the second positioning structure 120 has a contact plate, and the contact plate is contacted with one end of the side plate 620 in the length direction, so that the pre-positioning of the side plate 620 is realized. The predetermined position means that although the relative positions of the two side plates 620 are fixed and can be set up under the action of the first positioning structure 110, the second positioning structure 120 and the limiting seat 200, the two side plates 620 are still unstable, meanwhile, the two side plates 620 cannot be ensured to be completely parallel, and the space between the two side plates is not necessarily accurate, at this time, if the side plates 620 and the base 100 are directly welded, a high-precision welding effect is still difficult to achieve, and therefore other structures are required to further limit the two side plates 620.
