[0002] In the sheet metal processing industry, welding rectangular sheet metal parts is a common and important process. Traditional rectangular sheet metal welding processes present several problems. Positioning and clamping of rectangular sheet metal parts typically rely on manual operation, which is inefficient and makes it difficult to guarantee positioning accuracy. This results in inconsistent weld quality, easily leading to defects such as incomplete welds and missed welds. Consequently, the welded rectangular sheet metal parts exhibit significant dimensional deviations, resulting in unstable product quality. Summary of the Invention
[0003] The main purpose of this utility model is to provide a pneumatic welding auxiliary device for rectangular sheet metal parts, so as to solve the problems of low positioning and clamping efficiency, poor accuracy, inconsistent weld quality, and easy occurrence of defects such as false welding and missing welding when welding rectangular sheet metal parts in the prior art, thereby improving the welding quality and production efficiency of rectangular sheet metal parts and reducing labor intensity.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic welding auxiliary device for rectangular sheet metal parts, including a base, a left pneumatic clamping mechanism, a right pneumatic clamping mechanism, a positioning shaft, a left limiting device, and a right limiting device.
[0005] Furthermore, the base possesses excellent stability and load-bearing capacity, with multiple height-adjustable support feet at its bottom to adapt to work surfaces of varying flatness, ensuring the entire device remains stable and does not wobble or shift during welding. The left and right limiting devices are fixed to the front of the base, symmetrical about the vertical centerline of the worktable. The left and right pneumatic clamping mechanisms are fixed directly in front of the two limiting devices, also symmetrical about the vertical centerline of the worktable.
[0006] Furthermore, the left-side pneumatic clamping mechanism includes a support box, a limiting plate, a telescopic cylinder, and a side-end positioning claw. The support box and the limiting plate are fixed to the base. The side-end positioning claw is bolted to the telescopic rod of the telescopic cylinder, and the telescopic cylinder is bolted to the support box. The telescopic cylinder is connected to an external air source through an independent air pipe, and the telescopic rod of the telescopic cylinder is driven by air pressure to control the extension and retraction of the side-end positioning claw.
[0007] Furthermore, the right-side pneumatic clamping mechanism includes a support box, a telescopic cylinder, and a right-side positioning claw. Two rollers are mounted on both sides of the bottom of the right-side positioning claw. The support box is fixed to the base, and the right-side positioning claw is bolted to the telescopic rod of the telescopic cylinder, which is then bolted to the support box. The telescopic cylinder is connected to an external air source via an independent air pipe, and the telescopic rod of the cylinder is driven by air pressure to control the extension and retraction of the right-side positioning claw.
[0008] The beneficial effects of this utility model are as follows: The application of the pneumatic welding auxiliary device for rectangular sheet metal parts, through the coordinated action of the pneumatic clamping mechanism and the base positioning system, enables rapid and accurate positioning and firm clamping of rectangular sheet metal parts, effectively reducing the displacement and deformation of the sheet metal parts during welding, thereby improving welding accuracy and ensuring the dimensional accuracy and quality stability of the welded rectangular sheet metal parts.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] The present invention will be further described in detail with reference to the accompanying drawings: The application of the pneumatic welding auxiliary device for rectangular sheet metal parts provided by the present invention includes a base 1; a left pneumatic clamping mechanism 2; a right pneumatic clamping mechanism 3; a left limiting device 4; a right limiting device 5; a positioning shaft 6; a supporting square box 7; a telescopic cylinder 8; a limiting plate 9; a side positioning claw 10; and a right positioning claw 11.
[0017] Further description: The base 1 possesses excellent stability and load-bearing capacity. Its bottom is equipped with multiple height-adjustable support feet to adapt to work surfaces of varying flatness, ensuring the entire device does not shake or shift during welding. A left-side limiting device 4 and a right-side limiting device 5 are fixed to the front of the base 1. A left-side pneumatic clamping mechanism 1 and a right-side pneumatic clamping mechanism 2 are fixed directly in front of these two limiting devices. The left-side pneumatic clamping mechanism 1 includes a support box 7, a telescopic cylinder 8, a limiting plate 9, and a side positioning claw 10. The right-side pneumatic clamping mechanism 2 includes a support box 7, a telescopic cylinder 8, and a right-side positioning claw 11. The telescopic cylinder is connected to an external air source via an independent air pipe, and the telescopic rod of the telescopic cylinder is driven by air pressure to control the extension and retraction of the positioning claw.
[0018] Further description: Upon entering the production stage, the first step is to check whether the air pipe connection of the pneumatic clamping mechanism is secure and whether the external air source is working properly.
[0019] Further description: The left rectangular sheet metal part 13 is placed on the left side of the base 1, with its front end tightly fitted to the left limiting device 4 and its rear end tightly fitted to the limiting plate 9, restricting the left rectangular sheet metal part 13's lateral displacement relative to the base 1. The right rectangular sheet metal part 14 is placed on the right side of the base 1, with its front end tightly fitted to the right limiting device 5, restricting the right rectangular sheet metal part 14's lateral displacement relative to the base 1. The positioning shaft 6 then passes through the left limiting device 4 and engages with the corresponding positions of the left rectangular sheet metal part 13 and the right rectangular sheet metal part 14, and then passes through the right limiting device 5, restricting the front-to-back displacement of the rectangular sheet metal part welded 12 relative to the base 1.
[0020] Further description: By adjusting the position of the telescopic cylinder's telescopic rod, the side-end positioning claw 10 on the left pneumatic clamping mechanism 2 is controlled to accurately engage with the positioning hole on the rear end of the left rectangular sheet metal part 13, thus restricting the water flow between the left rectangular sheet metal part 13 and the base 1.
[0021] Displacement in the horizontal direction.
[0022] Further description: By adjusting the position of the telescopic cylinder telescopic rod, the position of the right positioning claw 11 on the right pneumatic clamping mechanism 3 is controlled, so that it can accurately cooperate with the positioning hole on the rear end of the right rectangular sheet metal part 14, thereby limiting the horizontal displacement of the right rectangular sheet metal part and the base 1.
[0023] After completing this series of precise positioning operations, welding work can officially begin. This precise positioning enables rapid and accurate positioning and secure clamping of rectangular sheet metal parts, effectively reducing displacement and deformation during welding, thereby improving welding accuracy and ensuring the dimensional accuracy and quality stability of the welded rectangular sheet metal parts. It also reduces manual intervention, lowers labor intensity, and improves the working environment.
