Technical Field

[0001] This utility model relates to the field of laser welding equipment, specifically to a laser welding fixture for the joint of a cylindrical workpiece. Background Technology

[0002] Metal cylinders are mainly produced by cutting and bending metal plates to obtain a cylinder body with seams. The ends of the cylinder body are provided with lugs for connecting with other components. In subsequent processing, the seams of the cylinder body need to be welded to ensure the product's sealing performance and structural strength.

[0003] When processing existing metal cylindrical parts, it is inconvenient to align the joints of the cylindrical parts, and when using general clamps to hold the cylindrical parts, it is not convenient to match the joints with a laser welder for welding processing. Therefore, a laser welding fixture for the joints of cylindrical workpieces is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a laser welding fixture for the joint of cylindrical workpieces, which can adapt to the alignment and automated clamping welding of the joint of the cylindrical workpieces, facilitate the loading and unloading of the cylindrical body, and improve the processing efficiency and processing quality of the cylindrical body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser welding fixture for the joint of a cylindrical workpiece, comprising a feeding base, on both sides of which are respectively provided a positioning component and a side push plate. The positioning component includes a support base and a positioning side plate. The support base is provided with a V-shaped groove. There are two positioning side plates, which are respectively fixed on the two inclined surfaces of the V-shaped groove. A processing gap is left between the two positioning side plates. A lifting mechanism is fixedly connected to the feeding base next to the positioning component. A laser welder is fixedly connected to the moving platform of the lifting mechanism. A positioning groove is opened at the bottom of each positioning side plate.

[0006] Furthermore, a pushing cylinder is fixedly connected to the lower part of the feeding base, the piston rod of the pushing cylinder is fixedly connected to the side pushing plate, and the side pushing plate is slidably connected to the feeding base.

[0007] Furthermore, the two positioning side plates are mirror-shaped on the V-groove, and the laser welder is located at the processing gap.

[0008] Furthermore, the positioning side plate is provided with an air extraction groove at one end near the processing gap.

[0009] Furthermore, the positioning side plate is fixedly connected to the support base by screws.

[0010] Furthermore, the lifting mechanism is specifically a screw lifting module.

[0011] The beneficial effects of this utility model are: the positioning component can be adapted to the alignment of the joints of the cylindrical parts.

[0012] By using positioning components, side push plates, lifting mechanisms and laser welders in combination, the cylinder can be clamped and welded automatically. After processing, the loading and unloading of the cylinder is convenient, improving the processing efficiency and quality of the cylinder. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] Example:

[0020] refer to Figures 1-4 The laser welding fixture for the joint of a cylindrical workpiece shown includes a feeding base 1. Positioning components and side push plates 2 are respectively provided on both sides of the feeding base 1. The positioning components include a support base 301 and positioning side plates 302. The support base 301 is provided with a V-shaped groove 3011. There are two positioning side plates 302, and the two positioning side plates 302 are respectively fixed on the two inclined surfaces of the V-shaped groove 3011. A processing gap 4 is left between the two positioning side plates 302. A lifting mechanism 5 is fixedly connected to the feeding base 1 next to the positioning components. A laser welder 6 is fixedly connected to the moving platform of the lifting mechanism 5. Each positioning side plate 302 has a positioning groove 3021 at the bottom.

[0021] A pusher cylinder 7 is fixedly connected to the lower part of the feeding base 1. The piston rod of the pusher cylinder 7 extends and retracts, which can drive the side push plate to slide along the feeding base 1 to clamp and release the cylinder. Two positioning side plates 302 are fixed on the inclined surface of the V-groove 3011. When the side push plate 2 presses the cylinder against the positioning side plate 302, the joint of the cylinder can fit together, improving the welding quality. The laser welder 6 is located at the processing gap 4 to avoid interference with the laser processing of the laser welder 6.

[0022] The positioning side plate 302 has an extraction groove at one end near the processing gap 4 to remove waste gas generated during laser welding. The positioning side plate 302 is fixedly connected to the support base 301 with screws, and the positioning side plate 302 can be directly installed and removed from the support base 301. Different positioning side plates 302 can be installed according to different processing needs. The lifting mechanism 5 is specifically a screw lifting module, which can more precisely control the lifting range of the laser welder 6 and improve the laser welding processing accuracy.

[0023] The working principle of this utility model is as follows: During processing, the piston rod of the pusher cylinder 7 first extends, and the lug at the bottom of the cylindrical part to be processed is placed on the unloading base 1 along the positioning groove 3021. The side push plate 2 presses the cylindrical part against the positioning side plate 302. Then, the lifting mechanism 5 drives the laser welder 6 to lift and weld the joint of the cylindrical part. After the welding process is completed, the piston rod of the pusher cylinder 7 extends again, the side push plate 2 loosens the clamp on the cylindrical part and slides it away from the side push plate 2. Finally, the cylindrical part is unloaded.

[0024] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
