DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figure 1-Figure 2As shown, a wind bag welding jig includes a chassis 2 and a rotating frame 1. The chassis 2 is circular and is composed of a plurality of fan-shaped metal frames or is integrally formed. The rotating frame 1 is rotatably set on the top of the chassis 2. A clamping mechanism 4 is provided on the rotating frame 1. A positioning mechanism for locking the rotating frame 1 is provided on the four corners of the rotating frame 1. The clamping mechanism 4 clamps and fixes the wind bag, thereby performing welding operations on the wind bag. A roller 9 is provided at the bottom of the rotating frame 1. The roller 9 is in rolling connection with the outer ring of the chassis 2, so that the rotating frame 1 can rotate on the chassis 2. By rotating the rotating frame 1 and locking it with the positioning mechanism, the welding operations of all welding surfaces of the wind bag are completed. The clamping mechanism 4 is a pair, which are arranged perpendicular to each other on the rotating frame 1 to fix the wind bag from multiple directions; the rotating frame 1 is square, with a plurality of connecting rods 3 and diagonal rods 12 in the middle to reinforce the rotating frame 1.

[0019] Furthermore, the positioning mechanism includes a positioning pin seat 10 , which is provided with a positioning pin hole 11 . When the rotating frame 1 is rotated to a fixed position, it only needs to insert a pin into the positioning pin hole 11 to complete the fixation.

[0020] Furthermore, the clamping mechanism 4 includes a pair of parallel movable grooves 401, a movable assembly in the movable groove 401, an inner clamping push rod 403, an outer clamping push rod 402, and a clamping cylinder 6. The outer clamping push rod 402 is fixed to the outer end of the movable assembly, the inner clamping push rod 403 is fixed to the middle of the movable assembly and maintains a certain distance from the outer clamping push rod 402, the clamping cylinder 6 is fixed on the center seat 5 of the chassis 2, and a cylinder push rod 7 is provided at the outer end of the clamping cylinder 6. The outer end of the cylinder push rod 7 is hinged to the connecting piece 8 provided at the bottom of the outer clamping push rod 402.

[0021] Furthermore, the moving component is provided with a moving track 408 in the moving groove 401, a pair of moving racks 404 that are slidably arranged along the moving track 408 and cooperate with each other to be pulled closer or farther away, and a center gear 406. The side of the moving racks 404 that are close to each other is provided with saw teeth 405, the outer end of the moving rack 404 is fixed with the outer clamping push rod 402, and the inner end of the moving rack 404 is provided with a connecting end 407, which is fixed to the inner end of the moving rack 404 and is slidably connected to the other moving rack 404, and the center gear 406 is meshed and connected with the moving racks 404 on both sides.

[0022] Furthermore, in order to facilitate the application of wind bags of different sizes, the inner clamping push rod 403 is fixed to the movable rack 404 by a locking screw, and the distance between the inner clamping push rod 403 and the outer clamping push rod 402 can be adjusted by the locking screw.

[0023] Working process of this utility model:

[0024] The clamping mechanism 4 is controlled to open by the clamping cylinder 6, and the wind bag is placed on the rotating frame 1. The position of the wind bag is adjusted so that the four sides of the wind bag are located in the clamping mechanism. The outer clamping push rods 402 are controlled to move closer to each other by the clamping cylinder 6, and the inner clamping push rods 403 are also driven to move closer to each other, so that the wind bag is clamped and fixed in multiple directions. The pins are inserted into the positioning pin holes 11 for fixing. At this time, the wind bag can be welded. When the welding of one surface is completed, only the pins need to be pulled out and the rotating frame 1 is rotated. When it is rotated to the required position, it is fixed with the pins again to weld the second surface. All welding work of the wind bag is completed in this way.

[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
