Description

Technical Field

[0001] The utility model relates to the technical field of spot welding equipment, in particular to a pneumatic spot welding machine. Background Art

[0002] A pneumatic spot welder is a type of spot welding equipment that uses pneumatic principles to drive it. Spot welding is a metal joining method that involves applying a high-current, short-duration arc to the contact point of the metal workpieces, causing the two metal surfaces to melt and connect instantly at high temperatures. Pneumatic spot welders are a type of machine that has evolved from traditional electric spot welders. Specifically, pneumatic spot welders use a pneumatic system to provide the required pressure and power, typically using compressed air generated by an air compressor. This design enables pneumatic spot welders to provide more stable and uniform pressure during operation, helping to ensure the quality and stability of the welds during the spot welding process. At the same time, compared to electric spot welders, pneumatic spot welders may have higher efficiency and reliability in some scenarios, especially when a large number of continuous welds are required.

[0003] Existing pneumatic spot welders rely on an air compressor to provide compressed air, and air must be transported between the compressor and the spot welder through pipes, making the spot welder difficult to move. Consequently, pneumatic spot welders often rely on moving the workpiece for processing, but moving the workpiece requires consideration of many issues, such as workpiece size and clamping, and suffers from poor precision.

[0028] refer to Figures 1 to 3 A pneumatic spot welding machine according to an embodiment of the present invention is described.

[0029] like Figures 1 to 3 As shown, the pneumatic spot welding machine of the embodiment of the present invention includes: a frame 100; a processing platform 200, which is horizontally arranged on the frame 100; a positioning mechanism, which is arranged on the frame 100, and is provided with a welding gun seat 310 and an air compressor seat 500, and the welding gun seat 310 and the air compressor seat 500 can move synchronously; a welding gun assembly 400, which is movably arranged on the welding gun seat 310; an air compressor 500, which is arranged on the air compressor seat 500, and the air compressor 500 is connected to the welding gun assembly 400 through an air pipe.

[0030] like Figures 1 to 3 As shown, the positioning mechanism includes a forward-backward moving assembly 330 and a left-right moving assembly 340. The left-right moving assembly 340 is mounted on the forward-backward moving assembly 330, and the air compressor 500 base and the welding gun base 310 are mounted on the left-right moving assembly 340. Two sets of forward-backward moving assemblies 330 are provided, one on each side of the frame 100, with the left-right moving assembly 340 spanning the other. The left-right moving assembly 340 includes a slide rail 341 extending in the left-right direction, and the welding gun base 310 includes a slider 311 mounted on the slide rail 341.

[0031] like Figure 2 As shown, the welding gun holder 310 also includes a reinforcement plate 312, which is bent toward the left-right movable assembly 340 and abuts against the left-right movable assembly 340. This reinforcement plate 312 serves to enhance the stability of the welding gun holder 310. The reinforcement plate 312 increases the overall rigidity of the welding gun holder 310 and prevents the welding gun assembly 400 from shaking during movement. The welding gun assembly 400 includes a cylinder 410 arranged vertically. A welding gun 420 is mounted at the lower end of the cylinder 410. The cylinder 410 drives the welding gun 420 up and down. An air compressor 500 is connected to the cylinder 410 via an air pipe. An illumination element 430 is mounted on the welding gun 420, facing the processing plane. This illumination element illuminates the workpiece being processed, making it easier for the operator to observe the workpiece and adjust the position of the welding gun 420.

[0032] like Figures 1 to 3As shown, the frame 100 is provided with a forward and backward moving assembly 330 on each side, and a left and right moving assembly 340 is arranged astride the two forward and backward moving assemblies 330. The two forward and backward moving assemblies 330 operate synchronously, driving the left and right moving assemblies 340 to move in the forward and backward direction. The left and right moving assemblies 340 are provided with slide rails 341, on which are mounted the welding gun holder 310 and the air compressor holder 500. The welding gun holder 310 and the air compressor holder 500 move synchronously in the left and right direction under the drive of the left and right sliding assemblies. The welding gun assembly 400 is mounted on the welding gun holder 310, and the air compressor 500 is fixed to the air compressor holder 500. As a result, when the forward and backward moving assembly 330 and the left and right moving assembly 340 drive the welding gun assembly 400 to move, the air compressor 500 moves synchronously with the welding gun assembly 400, keeping the welding gun assembly 400 and the air compressor 500 relatively stationary. This improves the stability of the air supply and prevents unstable air supply from affecting the quality and efficiency of spot welding.

[0033] The welding gun assembly 400 includes a cylinder 410, which is fixed to the welding gun base 310. This allows the air compressor 500 and cylinder 410 to remain relatively stationary. The cylinder 410 and the air compressor 500 are connected via an air pipe. A welding gun 420 is located at the lower end of the cylinder 410. The air compressor 500 supplies air to the cylinder 410 via an air pipe, thereby driving the vertical movement of the welding gun 420. By arranging the left-right movement assembly 340, the front-back movement assembly 330, and the cylinder 410, the welding gun 420 can process workpieces of varying sizes or different positions on the same workpiece on the processing platform 200. Movement of the welding gun does not affect the stability of the connection to the air compressor 500.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention.
