[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example 1

[0016] like Figure 1-3 As shown, the positioning fixture of the welding bracket for forklift provided by the utility model includes a base 1, and the base 1 is provided with a positioning hole 11 and a mounting hole 12. An L-shaped positioning support plate 2 is slidably connected to the base 1, and a slide groove 13 is provided on the upper side of the base 1. The L-shaped positioning support plate 2 slides back and forth in the slide groove 13. The base 1 and the L-shaped positioning support plate 2 are positioned and limited by a positioning pin 3. A pin hole 14 is provided at the bottom of the slide groove 13, and a limiting hole 23 is provided on the L-shaped positioning support plate 2. The positioning pin 3 passes through the limiting hole 23 and is inserted into the pin hole 14, thereby realizing the positioning and limiting between the base 1 and the L-shaped positioning support plate 2. A handle plate 22 is fixedly connected to one end of the L-shaped positioning support plate 2. When the positioning pin 3 is pulled out, the L-shaped positioning support plate 2 can be pushed or pulled to slide in the slide groove 13 by holding the handle plate 22.

[0017] The L-shaped positioning support plate 2 is fixedly connected to the positioning plate 4, and a mounting groove 41 is provided on one side of the positioning plate 4. A sliding hole penetrating the positioning plate 4 is provided on both sides of the mounting groove 41. The two sliding holes are staggered, and a sliding rod 61 is slidably connected in the sliding hole. One end of each sliding rod 61 is fixedly connected to the extension plate 6, and one end of each sliding rod 61 is fixedly connected to a rack 65. The tooth surfaces of the two racks 65 are arranged oppositely, and the mounting groove 41 is rotatably connected to the gear 64, and the two racks 65 are evenly meshed with the gear 64. The notch of the mounting groove 41 is fixedly connected to the cover plate 62, and the cover plate 62 is rotatably connected to the knob rod 63, and the knob rod 63 is fixed to the gear 64.

[0018] During use, the positioning fixture of the forklift welding bracket provided in this embodiment is used to position and fix the welding bracket 100 at a specified position of the forklift frame 300. The specific use steps are as follows: the forklift welding bracket and the forklift frame 300 provided in this embodiment are placed on the workbench 200, the base 1 is fixed on the upper surface of the workbench 200, and then the "U"-shaped welding bracket 100 is clamped on the upper side of the positioning plate 4, and the knob rod 63 is twisted to drive the gear to rotate. During the rotation process, the gear makes The extension plate 6 is translated, thereby locking the welding bracket 100 through the two extension plates 6, and then the L-shaped positioning support plate 2 is pushed to slide in the slide groove 13 through the handle plate 22, so that the welding bracket 100 fits with the forklift frame 300. At this time, the limit hole 23 and the pin hole 14 can just coincide, and the positioning pin 3 is passed through the limit hole 23 and inserted into the pin hole 14, so that the position of the L-shaped positioning support plate 2 is fixed, and then the welding bracket 100 and the forklift frame 300 can be welded together through the welding equipment. After the welding is completed, the knob rod 63 is rotated in the opposite direction to make the extension plate 6 leave the welding bracket 100, the positioning pin 3 is pulled out, and the L-shaped positioning support plate 2 is pulled back from the slide groove 13 through the handle plate 22, so that the positioning plate 4 leaves the forklift frame 300.
