Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, and specifically to an energy storage welding torch. Background Technology

[0002] An energy storage welding torch is a device that achieves efficient welding by pre-storing electrical energy and releasing it instantaneously. It is widely used in automobile manufacturing, electronic component assembly and other fields, and is especially suitable for welding workpieces with coatings such as galvanized surfaces. Its core structure includes an energy storage capacitor, a conductive block, a pressure spring and a motion mechanism. By precisely controlling the energy release and mechanical pressure, it ensures the high strength and consistency of the weld joint.

[0003] Existing energy storage welding torches typically store electrical energy through capacitor charging. When triggered, the energy is transferred to the welding point via a conductive block, while a pressure spring drives a piston to press the screw or welding stud onto the workpiece surface. During welding, the piston slides along a guide rail to maintain directional stability, and the basic pressure is adjusted through a mechanical structure. After welding is completed, the spring returns to its original position to prepare for the next operation.

[0004] In the existing technology, the energy storage welding gun has the following shortcomings: (1) When welding coated workpieces, uneven pressure can easily lead to incomplete welding or coating damage; (2) The screw has poor compatibility, requiring frequent replacement of the chuck and lacking a dedicated quick-release structure; (3) The spring pressure adjustment depends on experience and lacks digital display, resulting in low repeatability; (4) The gun shell material is not impact resistant, and the cable plug is easily burned out due to current overload; (5) The guide rail is not precise enough, welding spatter intrusion affects the service life, and the piston positioning error is large; (6) The overall weight is too high, limiting the flexibility of operation. These problems seriously restrict the improvement of welding quality and efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an energy storage welding torch to solve the technical problems in the prior art where uneven pressure easily leads to incomplete welding or coating damage when welding coated workpieces; spring pressure adjustment relies on experience and lacks digital display, resulting in low repeatability.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] An energy storage welding torch includes a torch housing, a main shaft, a conductive block, a pressure spring, and an adapter block. The torch housing is made of impact-resistant insulating plastic and has a precision guide rail inside, which is slidably connected to the welding torch piston. The conductive block is connected to the main shaft via the adapter block, and the end of the conductive block has a 50mm welding cable plug to prevent burnout. The pressure spring is located between the main shaft and the torch housing and is adjusted by a knob. The end of the welding torch piston has a replaceable screw chuck.

[0008] As a further embodiment of this invention: the adjustment knob of the pressure spring is linked to the digital pressure sensor, and the sensor data is displayed digitally on the LED screen of the welding machine. The pressure adjustment range is 5-50N, which can be adapted to the welding requirements of different coated workpieces.

[0009] As a further embodiment of this utility model: the screw chuck is made of high-temperature resistant alloy material, the inner wall of the chuck is provided with anti-slip texture, and the chuck is connected to the welding gun piston through a quick-release structure, supporting the welding of screws of various specifications.

[0010] As a further embodiment of this utility model: the surface of the precision guide rail is coated with an anti-spatter ceramic layer, and the gap between the guide rail and the welding gun piston is ≤0.1mm; the gun shell is equipped with a lightweight aluminum alloy bracket, and the overall weight is ≤1.5kg.

[0011] The beneficial effects of this utility model are as follows: By combining an impact-resistant insulating plastic gun shell with a lightweight aluminum alloy bracket, the weight of the equipment is significantly reduced and the insulation safety is improved; through a digital pressure adjustment system and real-time display, precise control of pressure from 5-50N is achieved, avoiding incomplete welding or damage to galvanized and other coated workpieces; equipped with a high-precision anti-spatter ceramic guide rail and a high-temperature resistant quick-release chuck, the screw positioning error is ensured to be ≤0.2mm, while also being compatible with multiple screw specifications and supporting second-level replacement; the anti-burn 50mm cable plug and high-temperature resistant chuck design significantly improve the durability of the equipment, effectively addressing welding spatter and current overload issues, ultimately achieving high repeatability, high reliability, and high-efficiency welding operations.

[0018] like Figures 1-3 As shown, an energy storage welding torch includes a torch housing 1, a main shaft 2, a conductive block 3, a pressure spring 4, and an adapter block 5.

The pressure spring 4 is located between the main shaft 2 and the torch housing 1, and the pressure spring 4 is adjusted by a knob. The end of the welding torch piston is provided with a replaceable screw chuck 6.

[0019] The gun housing 1 is made of impact-resistant insulating plastic, which combines lightweight and insulation safety; the high-precision fit between the precision guide rail and the welding gun piston ensures that the screw positioning error is ≤0.2mm during welding; the 50mm welding cable plug effectively avoids the problem of burnout caused by current overload by increasing the contact area and using copper alloy material.

[0020] The adjustment knob of the pressure spring 4 is linked to the digital pressure sensor. The sensor data is displayed digitally on the LED screen of the welding machine. The pressure adjustment range is 5-50N, which can adapt to the welding requirements of different coated workpieces.

[0021] The digital pressure sensor is integrated inside the pressure spring 4, which converts mechanical pressure into electrical signals and displays them digitally on the welding machine's LED screen.

[0023] The screw chuck 6 features a quick-release mechanism for one-click replacement. The anti-slip texture on the inner wall of the chuck is compatible with M3-M12 screws, ensuring clamping stability. The high-temperature resistant alloy material allows the chuck to withstand temperatures ≥800℃ during continuous welding.

[0025] The anti-splash ceramic layer on the guide rail surface is formed by plasma spraying, which can block more than 90% of welding spatter; the lightweight aluminum alloy bracket adopts a hollow design, which reduces the overall weight while ensuring structural strength and improving operational flexibility.

[0026] The working principle of this utility model is as follows: The gun shell 1 is made of impact-resistant insulating plastic, which combines lightweight and insulation safety; the high-precision matching between the precision guide rail and the welding gun piston ensures that the screw positioning error is ≤0.2mm during welding; the 50mm welding cable plug effectively avoids burnout caused by current overload by increasing the contact area and using copper alloy material; the digital pressure sensor is integrated inside the pressure spring 4, which converts mechanical pressure into electrical signals and displays them digitally on the welding machine's LED screen, allowing the operator to intuitively adjust the pressure to suit the welding of galvanized and other coated workpieces, avoiding insufficient pressure leading to poor welding or excessive pressure damaging the coating; the screw-specific chuck 6 can be replaced with one click through a quick-release structure, and the anti-slip texture on the inner wall of the chuck can be adapted to M3-M12 screws to ensure clamping stability; the high-temperature resistant alloy material allows the chuck to withstand temperatures ≥800℃ during continuous welding; the anti-spatter ceramic layer on the guide rail surface is formed by plasma spraying, which can block more than 90% of welding spatter; the lightweight aluminum alloy bracket adopts a hollow design, which reduces the overall weight while ensuring structural strength and improving operational flexibility.
