Description

Technical Field

[0001] This utility model relates to the field of chromium-zirconium-copper processing technology, and in particular to a chromium-zirconium-copper end ring welding device. Background Technology

[0002] Chromium-zirconium copper end rings are ring-shaped components made of copper alloys composed of metallic elements such as chromium, zirconium, and copper. They possess a variety of excellent properties and a wide range of applications. Chromium-zirconium copper end rings exhibit excellent electrical and thermal conductivity, making them outstanding in applications requiring efficient energy transfer and heat dissipation. Through cold working and precipitation strengthening treatments, chromium-zirconium copper end rings can achieve high strength and high hardness, thus meeting the stringent requirements for material mechanical properties in various applications.

[0003] A search revealed a welding device for a chromium-zirconium copper end ring with application number 202023018499.9. This device utilizes the telescopic property of an electric telescopic rod to move a fixed block forward, which in turn causes the connecting rod and rotating rod to extend, thereby making the rubber ring come into close contact with the inner wall of the chromium-zirconium copper end ring and thus fixing the chromium-zirconium copper end ring. The chromium-zirconium copper end ring is then welded using a welding machine.

[0004] In the above technical solution, the rubber ring is fixed to the chromium zirconium copper end ring by means of the cooperation of the telescopic mechanism, the fixing block, the connecting rod and the rotating rod. However, when fixing the chromium zirconium copper end ring in this way, the angle of the chromium zirconium copper end ring cannot be adjusted. Therefore, during welding, the entire ring surface of the chromium zirconium copper end ring cannot be welded, which affects the welding efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a chromium-zirconium-copper end ring welding device. By rotating the assembly sleeve, the chromium-zirconium-copper end ring inside the assembly sleeve can be driven to rotate synchronously, thereby realizing the rotational welding of the chromium-zirconium-copper end ring during welding. The rotational welding can be automated, reducing the complexity of manual operation and thus improving welding efficiency, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chromium zirconium copper end ring welding device, including a bearing base, a welding seat fixedly installed on the upper end surface of the bearing base, two welding seats are symmetrically arranged, and a ring connection drive assembly is provided on the inner and outer sides of the welding seats.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4 A chromium zirconium copper end ring welding device includes a support base 1, a welding seat 8 is fixedly installed on the upper end surface of the support base 1, two welding seats 8 are symmetrically arranged, and a ring connection drive assembly 7 is provided on the inner and outer sides of the welding seats 8.

[0027] The ring drive assembly 7 includes a servo motor 701 fixedly mounted on the upper surface of the support base 1. A transmission shaft 702 is fixedly mounted on the output end of the servo motor 701. An assembly groove 703 is opened inside the welding base 8. A drive gear 705 and a driven gear sleeve 704 are rotatably mounted inside the assembly groove 703. The drive gear 705 is located on the left side of the driven gear sleeve 704 and meshes with each other. An assembly sleeve 706 is fixedly connected inside the driven gear sleeve 704. The assembly sleeve 706 is rotatably connected to the welding base 8.

[0028] The welding base 8 is provided with a ring pressure assembly 6 both inside and outside. The ring pressure assembly 6 includes a pump body 601 fixedly installed on the right side of the upper end face of the bearing base 1. The rear end of the pump body 601 is fixedly connected to a hydraulic tank 602. The right end of the hydraulic tank 602 is fixedly connected to an elastic infusion tube 603. The output end of the elastic infusion tube 603 is fixedly connected to an annular pressure sleeve 604. The annular pressure sleeve 604 is embedded in the inside of the assembly sleeve 706.

[0029] When using the above technical solution, it should be noted that the size of the chromium-zirconium copper end ring to be welded must match the internal size of the mounting sleeve 706. This allows the chromium-zirconium copper end ring to be inserted into the mounting sleeve 706 from the opposite side of the welding seat 8. After placing the chromium-zirconium copper end rings into the two mounting sleeves 706 respectively, the pump body 601 is started. The operation of the pump body 601 pressurizes the inside of the hydraulic tank 602, thereby allowing the liquid in the hydraulic tank 602 to flow through the elastic infusion tube 60. 3. The liquid inside the annular sleeve 604 is increased by the delivery pipe, causing the annular sleeve 604 to expand. This expansion compresses and fixes the chromium-zirconium copper end ring inside the sleeve 706, thus applying pressure from the side end face of the chromium-zirconium copper end ring to ensure its stability during rotation. After the pump body 601 stops working and there is no pressure, the liquid inside the annular sleeve 604 can flow back into the hydraulic tank 602. After the chromium-zirconium copper end ring is fixed, the servo motor 701 is started. The servo motor 701 drives the transmission shaft 702 to rotate, and the rotation of the transmission shaft 702 drives the two drive gears 705 located in the welding seat 8 to rotate synchronously. This ensures that the chromium-zirconium copper end ring achieves synchronous rotation during rotational welding. The rotation of the drive gears 705 drives the meshing driven gear sleeve 704 to rotate. The driven gear sleeve 704 is fixedly connected to the mounting sleeve 706, which drives the mounting sleeve 706 to rotate, thereby driving the chromium-zirconium copper end ring inside the mounting sleeve 706 to rotate synchronously. This achieves rotational welding of the chromium-zirconium copper end ring during welding. It should be noted that the rotation angle range of the servo motor 701 is set from -180 degrees to +180 degrees, thus achieving a 360-degree rotational welding effect. The chromium-zirconium copper end ring does not perform welding work during retrograde rotation. At the same time, the elastic infusion tube 603 has its own telescopic effect, which can avoid the problem of the elastic infusion tube 603 winding during the rotational welding of the mounting sleeve 706.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, a support frame 2 is fixedly installed at the middle position of the upper end of the support base 1, and a hydraulic cylinder 3 is fixedly installed at the middle position of the upper end of the support frame 2. The telescopic end of the hydraulic cylinder 3 passes through the support frame 2 and is fixedly connected to a laser welding head 4. Both the front and rear ends of the upper surface of the support base 1 are provided with drive clamping assemblies 5. The drive clamping assembly 5 includes a fixed seat 501 fixedly installed at the front and rear ends of the upper surface of the support base 1. An electric telescopic rod 502 is fixedly installed on the side wall of the fixed seat 501 away from the welding seat 8. The telescopic end of the electric telescopic rod 502 passes through the fixed seat 501 and is fixedly connected to an assembly seat 503. A bearing 505 is fixedly connected inside the assembly seat 503. A push rod 504 is rotatably connected inside the bearing 505. The diameter of the push rod 504 matches the internal diameter of the assembly sleeve 706.

[0031] By adopting the above technical solution, after the chromium-zirconium copper end rings to be processed are placed into the two mounting sleeves 706, the electric telescopic rods 502 on both sides are activated. The operation of the electric telescopic rods 502 can drive the mounting base 503 and the push rod 504 to move telescopically, thereby inserting the push rod 504 into the interior of the mounting sleeve 706 and pressing the chromium-zirconium copper end rings from both sides, so that the welding joints of the two chromium-zirconium copper end rings are aligned with each other, thus ensuring the stability of the chromium-zirconium copper end rings during welding. At this time, the ring pressing assembly 6 applies pressure and fixes the chromium-zirconium copper end rings from the side end face, thereby ensuring the stability of the chromium-zirconium copper end rings. The stability of the end ring during welding is ensured by the top rod 504, which abuts against the chromium-zirconium-copper end ring, rotating on the mounting base 503 via the bearing 505 during the rotational welding of the chromium-zirconium-copper end ring. This allows the rod to rotate synchronously with the rotating chromium-zirconium-copper end ring, reducing interference with its rotation. During welding, the hydraulic cylinder 3 is activated, and its extension and retraction can move the laser welding head 4 away from or towards the chromium-zirconium-copper end ring. When the head is close to the chromium-zirconium-copper end ring, the laser welding head 4 of the laser welding equipment can perform laser welding on the chromium-zirconium-copper end ring, thus completing the welding of the chromium-zirconium-copper end ring.

[0032] Working Principle: When using this device, it is important to note that the dimensions of the chromium-zirconium copper end ring to be welded must match the internal dimensions of the mounting sleeve 706. This allows the chromium-zirconium copper end ring to be inserted into the mounting sleeve 706 from the opposite side of the welding seat 8. After placing the chromium-zirconium copper end rings into the two mounting sleeves 706, activate the electric telescopic rods 502 on both sides. The operation of the electric telescopic rods 502 drives the mounting seat 503 and the push rod 504 to extend and retract, thereby inserting the push rod 504 into the mounting sleeve 706 and pressing the chromium-zirconium copper end rings from both sides, aligning the weld joints of the two chromium-zirconium copper end rings. Then, activate the pump body 601. The operation of the pump body 601 pressurizes the hydraulic tank 602, allowing the liquid in the hydraulic tank 602 to be transported through the elastic infusion tube 603 to the annular pressure sleeve 604. The increased liquid inside sleeve 604 causes it to expand, which in turn compresses and fixes the chromium-zirconium copper end ring inside the assembly sleeve 706. This pressure is applied from the side end face of the chromium-zirconium copper end ring. Once fixed, servo motor 701 is activated, driving drive shaft 702 to rotate. The rotation of drive shaft 702 drives two drive gears 705 located in welding seat 8 to rotate synchronously, ensuring that the chromium-zirconium copper end ring rotates synchronously during welding. The rotation of drive gears 705 drives the meshing driven gear sleeve 704 to rotate. The driven gear sleeve 704 is fixedly connected to the assembly sleeve 706, which in turn drives the assembly sleeve 706 to rotate, thereby causing the chromium-zirconium copper end ring inside the assembly sleeve 706 to rotate synchronously, thus achieving the rotational welding of the chromium-zirconium copper end ring during welding.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
