Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding fixture for a rain cover. Background Technology

[0002] A rain cover is a waterproof protective cover made of metal, which generally consists of an arc-shaped main body and crossbeams welded to the main body to enhance its structural strength. However, when welding rain covers, existing welding fixtures are unable to effectively and stably clamp the arc-shaped main body of the rain cover, that is, they cannot effectively position and press it, which makes the rain cover prone to dimensional deviations during welding, thus affecting the quality of its welding process. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a welding fixture for a rain cover.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A welding fixture for a rain cover includes a bracket for placing the rain cover, with crossbeams to be welded spaced apart on the rain cover, a welding torch on the bracket, a slide on the bracket, a sliding plate that abuts against the rain cover on the slide, and a stop bar on the bracket that abuts against the rain cover. The slide and the stop bar are staggered. Hooks on both sides of the slide are rotatably engaged with the sides of the rain cover, and a stop bar is connected to the hook. The stop bar moves and abuts against both ends of the crossbeams.

[0006] Preferably, the slide is provided with rotating plates on both sides, and a fixing frame is fixed on the hook, with a connecting bolt threaded to the rotating plate on the fixing frame.

[0007] Preferably, a connecting plate is connected between the hooks on the same side, and the connecting plate is threaded with an abutment bolt that abuts the abutment frame.

[0008] Preferably, the support frame is provided with a sliding groove, and the hook is provided with a limiting post that extends into the sliding groove.

[0009] Preferably, the carriage is equipped with a lead screw motor that drives the sliding plate to move up and down, and the sliding plate is disposed against the inner wall of the carriage.

[0010] Preferably, the upper end of the skateboard is provided with a stop post that abuts against the rain cover.

[0011] Preferably, the bracket is provided with a slide bar for the slide to slide, and a support frame for mounting the welding gun is provided above the slide bar.

[0012] Preferably, the welding guns are multiple and spaced apart on the support frame. The support frame is equipped with a motor and a lead screw. A limiting sleeve is provided on the outer periphery of the lead screw. A slider is screwed onto the lead screw inside the limiting sleeve. The welding gun is fixed downward to the slider.

[0013] The beneficial effects of this utility model are:

[0014] 1. A sliding plate is installed on the carriage to abut against the rain cover. The sliding plate and the abutment are staggered to abut against the rain cover, so as to support the rain cover to be welded at multiple points. The sides of the rain cover are fixed by the hooks on both sides of the carriage to secure the rain cover stably and reliably. At the same time, the hooks are equipped with abutments that abut against both ends of the positioning crossbeam to ensure the accuracy of the welding and fixing dimensions between the crossbeam and the rain cover, thereby improving the quality of the welding process.

[0015] 2. A threaded connecting bolt is installed on the fixing frame of the hook to connect the rotating plate. The hook and the rotating plate can be detachably connected by the connecting bolt and the fixing frame. By tightening the connecting bolt, the hook can be more reliably fixed to the side of the rain cover. The sliding plate and the abutment rod abut against the rain cover at multiple points to prevent the rain cover from deforming during the fixing process, which would affect the welding accuracy and quality, thus improving the yield rate of the rain cover welding.

[0016] 3. Multiple welding torches capable of welding the rain cover to the crossbeam are installed on the support frame, and spot welding is performed by the cooperation of multiple welding torches, thereby improving the efficiency of the rain cover welding process. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1-6 As shown, a welding fixture for a rain cover includes a bracket 1 for placing the rain cover 4. The rain cover 4 has crossbeams 41 to be welded spaced apart. By welding and fixing the crossbeams 41 to the rain cover 4, the overall structural strength of the rain cover 4 is improved. The bracket 1 is provided with two abutting rods 12 that abut against the rain cover 4. The two abutting rods 12 extend along the length of the bracket 1 and cooperate with each other to abut against the rain cover 4 upwards.

[0027] The bracket 1 is provided with a slide 2, and the bracket 1 is provided with a slide rod 11 for the slide 2 to slide. The slide 2 can slide back and forth along the length direction of the slide rod 11, that is, the slide 2 can slide along the length direction of the abutment rod 12.

[0028] The bracket 1 is equipped with a welding torch 3. Specifically, a support frame 13 for mounting the welding torch 3 is provided above the slide rod 11. The welding torch 3 is a plurality of torches and is distributed at intervals on the support frame 13. The support frame 13 is equipped with a motor 31 and a lead screw 32. The output end of the motor 31 is connected to the lead screw 32. A limit sleeve 33 is provided on the outer periphery of the lead screw 32. A slider 34 is screwed to the lead screw 32 inside the limit sleeve 33. The outer periphery of the slider 34 abuts against the limit sleeve 33. The motor 31 drives the slider 34 to move up and down through the lead screw 32.

[0029] The welding torch 3 is fixed downward to the slider 34. The slider 34 drives the welding torch 3 to move up and down, so that the welding torch 3 can weld the rain cover 4 and the crossbeam 41 downward. Furthermore, by setting multiple welding torches 3 on the support frame 13 that can weld the rain cover 4 and the crossbeam 41 downward, and by having multiple welding torches 3 cooperate with each other to perform spot welding, the efficiency of the welding process of the rain cover 4 is improved.

[0030] The slide 2 is equipped with a sliding plate 22 that abuts against the rain cover 4. Specifically, the slide 2 is equipped with a screw motor 21 that drives the sliding plate 22 to move up and down. The sliding plate 22 is abutted against the inner wall of the slide 2. There are four sliding plates 22, which abut against the rain cover 4 at intervals. The sliding plates 22 and the abutment rod 12 are distributed alternately to support the rain cover 4 to be welded through multiple points inside and outside.

[0031] The upper end of the slide plate 22 is provided with a stop post 221 that abuts against the rain cover 4, and the arc side wall of the stop post 221 abuts against the rain cover 4.

[0032] The slide 2 is provided with two hooks 24 on both sides for rotating and engaging the sides of the rain cover 4. There are two hooks 24 on the same side, that is, the sides of the rain cover 4 are engaged and fixed by the hooks 24 on both sides of the slide 2 to secure the rain cover 4 stably and reliably.

[0033] Furthermore, a stop 25 is connected to the hook 24. The stop 25 moves and abuts against both ends of the crossbeam 41 to position the welded crossbeam 41 by abutting against the crossbeam 41. Specifically, a connecting plate 243 is connected between the hooks 24 on the same side. The connecting plate 243 is threaded with abutting bolt 244 that abuts against the stop 25. The stop 25 is provided with a sliding groove 251. The hook 24 is provided with a limiting post 245 that extends into the sliding groove 251. That is, the stop 25 is displaced by cooperating with the limiting post 245 through the sliding groove 251.

[0034] Furthermore, by setting abutment brackets 25 on the hook 24 to abut the two ends of the positioning beam 41, the accuracy of the welding and fixing dimensions of the beam 41 and the rain cover 4 can be ensured, thereby improving the quality of the welding process.

[0035] The slide 2 has rotating plates 23 on both sides, and the rotating plates 23 are corresponding to the hooks 24. The hooks 24 are fixed with a fixing frame 241. The fixing frame 241 is provided with a connecting bolt 242 threaded to the rotating plate 23, so that the hooks 24 and the rotating plates 23 can be detachably connected by the connecting bolt 242 cooperating with the fixing frame 241.

[0036] Furthermore, by tightening the connecting bolts 242, the hooks 24 are driven to more reliably fix the side of the rain cover 4, and the slide plate 22 and the abutment rod 12 abut against the rain cover 4 at multiple points to avoid deformation of the rain cover 4 during the snap-fit ​​fixing process, which would affect the accuracy and quality of its welding, thus improving the yield rate of the rain cover 4 welding.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
