[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-4 As shown, the utility model is a sheet metal welding fixture, including a fixture base 1 and a support frame 2 fixedly arranged on the upper end of the fixture base 1. When performing circumferential welding of two cylindrical sheet metal parts, the two cylindrical sheet metal parts are sleeved on the support rod 13 arranged in the middle part of the fixture, and the positioning adjustment screw 5 threadedly connected to one side of the fixture base 1 is rotated, so that the auxiliary clamping disk 6 rotatably connected to the end of the positioning adjustment screw 5 close to the support frame 2 is close to the support frame 2, and the linkage ring 10 is sleeved on the outside of the positioning adjustment screw 5, and the linkage ring 10 is in contact with the support frame 2. When the auxiliary clamping disk 6 approaches the support frame 2, the distance between the linkage ring 10 and the auxiliary clamping disk 6 is reduced, and the edge of the linkage ring 10 is rotatably connected to a connecting rod 9, and the end of the connecting rod 9 away from the linkage ring 10 is rotatably connected to a slider 8, and the side of the auxiliary clamping disk 6 close to the support frame 2 is opened There is a slide groove 7. When the distance between the linkage ring 10 and the auxiliary clamping disk 6 is reduced, the linkage ring 10 squeezes the slider 8 slidably connected to the inside of the slide groove 7 through the connecting rod 9, so that the slider 8 slides outward, thereby driving the support rod 13 welded on the side of the slider 8 away from the connecting rod 9 to expand outward, thereby propping up the cylindrical sheet metal. When the cylindrical sheet metal is completely fitted with the rubber protective strip 14 bonded to the outside of the synchronization rod 12, the rotation of the positioning adjustment screw 5 is stopped, and the positioning of the two cylindrical sheet metals is completed. The three groups of positioning mechanisms composed of the slide groove 7, the slider 8, the connecting rod 9 and the linkage ring 10 arranged around the positioning adjustment screw 5, cooperate with the support rod 13 used to support the cylindrical sheet metal, play a role in positioning the center of the cylindrical sheet metal, so that the welding points of the two cylindrical sheet metals are accurately butted, which is beneficial to improving the quality of welding.

[0023] After the two cylindrical sheet metal parts are positioned on site by the positioning mechanism, the clamping adjustment screw rod 3 threadedly connected to the other side of the upper part of the clamp base 1 is rotated, and the clamping adjustment screw rod 3 drives the main clamping plate 4 connected to the end close to the support frame 2 to move closer to the auxiliary clamping plate 6, and the main clamping plate 4 squeezes the two cylindrical sheet metal parts sleeved on the outside of the support rod 13, and with the cooperation of the main clamping plate 4 and the auxiliary clamping plate 6, the cylindrical sheet metal parts placed therebetween are clamped, and a protective pad 16 is bonded to the side of the main clamping plate 4 away from the support frame 2, and the auxiliary clamping plate 6 is away A protective pad 15, a rubber protective pad 15 and a protective pad 2 16 are bonded to one side away from the support frame 2, which effectively prevent the deformation of the sheet metal when the cylindrical sheet metal is clamped. After the positioning and clamping of the cylindrical sheet metal are completed, the cylindrical sheet metal can be welded. Since the main clamping plate 4 is rotatably connected to the clamping adjustment screw rod 3, the auxiliary clamping plate 6 is rotatably connected to the positioning adjustment screw rod 5, and the synchronous rod 12 welded on the edge of the linkage ring 10 is slidably connected to the auxiliary clamping plate 6, when the cylindrical sheet metal is rotated, the main clamping plate 4, the auxiliary clamping plate 6 and The linkage ring 10 rotates synchronously. When welding two cylindrical sheet metal parts, the sheet metal parts are rotated while welding. The cylindrical sheet metal parts have good rotation stability and can complete circumferential welding at one time. Continuous welding is conducive to improving the quality of welding and the efficiency of processing. In addition, since there is no need for multiple people to support the cylindrical sheet metal parts, the labor intensity of the staff can be reduced. A spring 11 is provided at the center of one side of the auxiliary clamping plate 6 close to the support frame 2, and the spring 11 is sleeved on the outside of the positioning adjustment screw rod 5. After the welding is completed, the clamping adjustment screw rod 3 is rotated in the opposite direction. , the clamping and adjusting screw rod 3 drives the main clamping plate 4 away from the auxiliary clamping plate 6, so that the main clamping plate 4 no longer clamps the welded cylindrical sheet metal, and then the positioning and adjusting screw rod 5 is rotated in the opposite direction to make the auxiliary clamping plate 6 close to the main clamping plate 4. Under the action of the spring 11, the distance between the auxiliary clamping plate 6 and the linkage ring 10 is increased, and then the connecting rod 9 rotatably connected to the linkage ring 10 drives the slider 8 slidably connected to the inside of the slide groove 7 to move inward, so that the support rod 13 welded on one side of the slider 8 shrinks toward the middle, and the welded cylindrical sheet metal can be taken out.

[0024] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
