Description

Technical Field

[0001] This invention relates to the field of metal welding equipment technology, specifically a high-power dual-head energy storage welding machine. Background Technology

[0002] Energy storage welding machines utilize capacitors to store electrical energy and release it instantaneously to generate a large current, enabling rapid welding of workpieces. They are widely used in hardware processing, automotive parts manufacturing, and electronic component assembly. Among them, high-power dual-head energy storage welding machines have become core equipment in metal welding production scenarios due to their advantages such as simultaneous operation of two welding heads, high welding efficiency, and low energy consumption.

[0003] However, existing high-power dual-head energy storage welding machines still face the following pressing technical problems in practical use: 1. Poor support effect at the workpiece welding joint: The welding auxiliary support structure of existing welding machines is mostly a fixed rigid structure, which cannot be adaptively adjusted according to the shape of the contact surface at the workpiece welding joint. For irregularly shaped workpieces, the support point is prone to offset and uneven force, which causes the workpiece to shake during the welding process, thus affecting the welding accuracy and causing defects such as weld offset, incomplete welding, and weld failure, reducing the product qualification rate.

[0004] 2. Inconvenience in lifting long workpieces: When welding long workpieces, one end of the workpiece overlaps on the welding positioning fixture, while the other end is suspended in the air, requiring manual support throughout the process to ensure the workpiece's stability. Manual support not only increases the operator's workload but also suffers from poor stability, easily leading to workpiece displacement due to hand tremors. Furthermore, it poses safety hazards such as burns from the high-temperature welding head or injuries from being struck by the workpiece.

[0005] To address the aforementioned technical issues, there is an urgent need for a high-power dual-head energy storage welding machine that can solve problems such as poor support at the weld joint and inconvenience in lifting long workpieces, in order to improve welding accuracy, reduce labor intensity, increase production efficiency, and meet the needs of industrialized mass production.

[0031] In some embodiments of the present invention, reference is made to... Figure 5 - Figure 8 As shown, the locking socket part 410 includes a circular ring box 411, a locking insert assembly 412, an inflation piston valve 413, an inflation airbag 414, an inflation port 415, a clearance hole 416, and a bottom sealing plate 417.

The square insertion tube 401 is fixed inside the annular box 411, the pressing port 402 is opened on the side wall of the square insertion tube 401, and the locking spring plate 403 is fixed inside the pressing port 402.

[0033] The support pin assembly 420 includes a support guide post 421, a return spring 422, a spring stop 423, and a flexible ring 424.

The flexible ring 424 is detachably connected to the top end of the support guide post 421 for contacting the workpiece.

[0034] Under normal conditions, the locking spring plate 403 provides only slight preload damping, allowing the support guide post 421 to move freely up and down under the workpiece's gravity, automatically conforming to the irregular surface of the weld joint. Once all support guide posts 421 are in place, the electric telescopic rod 430 pushes the inflation piston valve 413 to inflate the airbag 414, causing the inflated airbag to compress all locking spring plates 403, generating sufficient radial pressure and simultaneously locking the position of all support guide posts 421, achieving stable multi-point support. After welding is completed, the airbag 414 deflates, the locking force disappears, and the return spring 422 pushes the support guide posts 421 to automatically reset.

[0035] Two sets of electric telescopic poles 430 are provided, and the two sets of electric telescopic poles 430 are respectively installed on the lower end faces of both ends of the Y-shaped boom 250.

[0036] The support pin assembly 420 of the welding auxiliary support mechanism 400 can be adaptively adjusted according to the shape of the contact surface at the welding point of the workpiece. The support guide post 421 is elastically abutted against the square insertion tube 401 by the locking spring plate 403, which locks the position of the support guide post 421 so that the upper end of the support guide post 421 can closely fit the irregular surface of the welding point of the workpiece, realize multi-point adaptive support, avoid workpiece shaking during welding, improve welding accuracy, reduce defects such as weld seam offset and incomplete welding, and improve product qualification rate. At the same time, the flexible ring 424 can prevent the support guide post 421 from scratching the surface of the workpiece and ensure the appearance quality of the workpiece.

[0037] When using this high-power dual-head energy storage welding machine, first place the workpiece to be welded on the lower T-shaped platform 143 of the workpiece positioning fixture assembly 140, adjust the position of the workpiece so that the welding point is aligned with the lower welding electrode head 144 and corresponds vertically with the upper welding electrode head 134; for longer workpieces, place the suspended end on the tray 328 of the workpiece auxiliary lifting mechanism 300, adjust the position and height of the tray 328 to ensure that the workpiece is in a horizontal and stable position, tighten the relevant locking parts to fix the workpiece and the tray 328.

[0038] The weld joint of the workpiece is pressed against the flexible ring 424 of the support pin assembly 420, causing the support guide post 421 to adaptively move downward according to the irregular surface of the workpiece weld joint. This allows the upper end of the support guide post 421 to closely fit the irregular surface of the workpiece weld joint. Under the action of the return spring 422, the support guide post 421 can adaptively fit the irregular surface of the workpiece weld joint, achieving multi-point support and preventing the workpiece from shaking during welding. The telescopic end of the electric telescopic rod 430 extends and pushes the piston end of the inflation piston valve 413, causing the inflation piston valve 413 to work and inflate the inflation bladder 414. After the inflation bladder 414 expands, it squeezes the locking spring plate 403, further locking the support guide post 421 and ensuring stable support.
