Description

Technical Field

[0001] The present invention relates to the field of welding technology, and in particular to a rotary welding device and method for producing compressed air energy storage tanks. Background Art

[0002] In the production process of compressed air energy storage tanks, the quality and efficiency of welding operations play a decisive role in the overall performance of the product. At present, although there are a variety of tank welding devices on the market, when actually used in the manufacture of compressed air energy storage tanks, especially in the positioning of welding guns and grinding tools, a considerable number of devices still rely on manual operation. Operators rely on experience and visual judgment to move and fix welding guns and grinding tools, which makes the operating accuracy susceptible to human factors. The operating habits and skills of different operators will cause significant fluctuations in welding quality. In large-scale industrial production, this quality instability seriously hinders the improvement of product quality.

[0003] Some existing devices cannot provide reliable support and precise positioning reference for the tank body due to structural design limitations or imperfect mechanical transmission. A Chinese patent discloses "a welding device for a dosing device tank body" with the publication number "CN118385880A". It uses a welding device for a dosing device tank body. The support seat on the base supports the outside of the tank body. The bracket drives the welding part installed on the welding support rod to move. The welding support rod extends into the inside of the tank body and can perform welding operations on the inside of the tank body. The tank body is placed on the support seat. When the tank body rotates, the inside of the tank body is welded in a whole circle. However, it performs poorly in adapting to energy storage tanks of different diameters. Its clamping parts are usually fixed in specifications or have only limited adjustment capabilities, making it difficult to quickly and accurately adapt to the processing needs of tanks of different sizes.

[0004] In addition, there are also deficiencies in the preparation process before welding. Before welding, a reasonable groove design is crucial to the welding quality. Traditional devices often lack an effective groove opening mechanism, and the present invention innovatively uses an angle grinder to drive a V-shaped grinding wheel to open a V-shaped notch at the tank body welding point. The opening of this V-shaped notch can significantly increase the welding surface and make the weld filling more sufficient. In the subsequent welding process, as the tank body rotates, it can ensure that the V-shaped notch is evenly distributed around the tank body, thereby greatly improving the welding strength and quality, effectively making up for the shortcomings of the prior art in this regard, and providing a strong guarantee for the high-quality welding of compressed air energy storage tanks.

[0005] In view of the above deficiencies in the prior art, the present invention proposes a new rotary welding device and method for the production of compressed air energy storage tanks, so as to effectively solve the above problems, improve production efficiency, ensure welding quality, and enhance the safety and reliability of energy storage tank products, so as to meet the growing market demand and industry development requirements. Summary of the invention

[0006] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a rotary welding device and method for the production of compressed air energy storage tanks. Through the cooperation of the welding adjustment component and the welding auxiliary clamping component, the telescopic rod 2 is used to drive the linkage frame to move. The linkage frame uses the guide wheel to make the clamping arm 1, clamping arm 2, clamping arm 3, and clamping arm 4 move synchronously. The distance between the active roller, auxiliary roller 1 and auxiliary roller 2 can be quickly adjusted according to the outer diameter of the tank body, so as to adapt to tanks of different diameters, thereby improving the versatility of the device, reducing the equipment adjustment time caused by changes in the tank size, and improving production efficiency.

[0007] The second drive motor controls the movement of the active roller and related components through the one-way bearing, which can adjust the tilt angle of the flap and drive the tank body to rotate; the first drive motor drives the reciprocating screw to move the movable seat, and sends the welding gun and angle grinder to the welding position; the double-output shaft motor realizes the movement of the movable frame and welding gun seat through the one-way bearing and gear box and other components, completes the welding preparation and the small movement of the welding gun, reduces manual operation, and improves welding accuracy and consistency.

[0008] Before welding, a V-shaped notch is opened at the tank body welding point using a V-shaped grinding wheel on an angle grinder to make the weld fill more fully during welding. Combined with the rotation of the tank body, it can be ensured that the V-shaped notch is evenly distributed around the tank body.
