Description

Technical Field

[0001] This utility model relates to the field of turbine machining technology, and in particular to a welding device for turbine machining. Background Technology

[0002] Turbine machining is a precision manufacturing process for core components such as blades, impellers, and integral impellers in aircraft engines, gas turbines, and automotive turbochargers. Its core lies in the efficient cutting and shaping of high-strength, high-temperature resistant alloy materials. It typically uses five-axis CNC machine tools combined with high-precision cutting tools to machine complex spatial curved surfaces, ensuring the streamlined structure and aerodynamic performance of the blades. At the same time, through the coordinated application of various processes such as milling, turning, grinding, and electrical discharge machining, it can not only ensure the surface finish and dimensional accuracy of the parts, but also improve the consistency and stability of the products, thereby meeting the reliable operation requirements of turbines under high-speed rotation and extreme conditions.

[0003] In the traditional welding process of worm gears, the operation is usually carried out manually by holding a welding gun and a wire, which has significant limitations. First, the operator needs to hold the welding gun with one hand and control the feeding of the wire with the other hand. This is not only labor-intensive, but also prone to hand tremors or unstable operation during long-term operation, resulting in quality problems such as uneven heating of the welding point, weld misalignment, or even incomplete welding. Secondly, it is difficult to maintain a consistent wire feeding speed and angle during the welding process, which can easily lead to excessive or insufficient solder accumulation, thereby affecting the bonding strength and overall durability between the worm gear and the mating parts.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Implementation examples, based on Figures 1-4 As shown in the figure, the present invention provides a welding device for turbine processing, including a support base 1 for mounting on a CNC robot, a welding pipe 4 mounted on the support base 1, and a wire assembly 6. The wire assembly 6 includes a sleeve 601 fixed to the end of the welding pipe 4. The lower part of the sleeve 601 has a through hole for passing solder wire. A drive gear 606 mounted on the sleeve 601 rotates through a motor 604 fixed on the sleeve 601. The lower part of the drive gear 606 is located in the through hole, driving and guiding the solder wire.

[0017] The aforementioned welding device for turbine processing enables automated welding operations by fixing the weld pipe 4 on the support base 1, allowing it to be integrated and linked with a CNC robot. The end of the welding pipe 4 is provided with a wire assembly 6. The wire assembly 6 includes a sleeve 601 structure. The lower part of the sleeve 601 is specially provided with a through hole for the solder wire to pass through, so that the solder wire can be accurately fed into the welding point along a fixed path. A drive gear 606 is rotatably mounted on the outside of the sleeve 601. The drive gear 606 is connected to a motor 604 fixed on the sleeve 601. When the motor 604 runs, it drives the drive gear 606 to rotate. The lower part of the drive gear 606 is located inside the through hole, which can stably drive and guide the solder wire passing through. With this structure, the feeding speed and direction of the solder wire are precisely controlled by the motor 604, eliminating the need for manual handling and thus ensuring the continuity and uniformity of solder joint feeding. With the help of CNC robots to control the movement of the welding torch, high-precision alignment of the solder joint position and automatic supply of solder wire can be achieved, making the welding of turbine components more efficient and stable, and significantly improving welding quality and production efficiency.

[0018] In this embodiment, a support arm 2 is rotatably mounted on one side of the support base 1, and a welded pipe 4 is fixedly mounted on the upper part of the support arm 2. A pin 3 is screwed onto one side of the support base 1. When in use, the pin 3 is inserted into pin holes opened at different positions on the support arm 2 to realize the angle adjustment action of the support arm 2. A nozzle 5 is screwed onto the end of the welded pipe 4. A sleeve 601 is sleeved and installed on the outside of the welded pipe 4. The outside of the sleeve 601 is fixed to the upper part of the welded pipe 4 by a screw 602. A guide frame 603 is also clamped and fixed between the sleeve 601 and the screw 602. After the angle of the guide frame 603 is set, it is fixed by rotating the screw 602. The screw 602 passes through the sleeve 601 and is screwed onto the welded pipe 4 to realize the fixing operation.

[0019] During use, the support base 1 serves as the basic load-bearing component, with a support arm 2 rotatably mounted on one side. The angle can be adjusted by the cooperation of the pin 3 and the pin hole. According to different welding positions and process requirements, the operator can insert the pin 3 into the pin hole at different positions on the support arm 2 to lock the angle of the support arm 2, so that the welded pipe 4 can be in a suitable working position.

[0020] The upper part of the welding pipe 4 is fixedly installed at the end of the support arm 2 to ensure stable position during welding. The end of the welding pipe 4 is equipped with a nozzle 5 by screw connection. The nozzle 5 can accurately spray solder wire or solder to the designated welding point to improve welding accuracy.

[0021] The sleeve 601 is fitted onto the outside of the welded pipe 4 and fixed to the upper part of the welded pipe 4 by an external screw 602, forming a stable limiting and protective function. A guide frame 603 is clamped and fixed between the sleeve 601 and the screw 602. The guide frame 603 can be angled according to process requirements before welding. After the angle is adjusted to the correct position, it is tightened by rotating the screw 602, thereby ensuring the stability and accuracy of the solder wire guidance during the welding process.

[0022] Ultimately, the screw 602 not only locks the guide frame 603, but also penetrates the sleeve 601 to form a reliable connection with the welded pipe 4, making the overall structure more stable and avoiding displacement caused by vibration or operational deviation during the welding process, thus ensuring the continuity and consistency of the welding operation.

[0023] In this embodiment, the motor 604 is fixedly mounted on the guide frame 603, and a through hole is opened in the lower part of the guide frame 603. Several guide components are circumferentially arranged at the through hole position of the guide frame 603. The guide components include a spring telescopic rod 608 fixedly mounted inside the guide frame 603, and a guide wheel 610 is rotatably mounted on one side of the support plate 609 fixed on the upper part of the spring telescopic rod 608. The guide wheel 610 is partially located in the through hole and performs a rolling guide action on the solder wire passing through. The drive gear 606 is rotatably mounted on the support plate 609 of one of the guide components. In use, the spring telescopic rod 608 realizes the automatic adaptation action for solder wires with different diameters. In addition, a magnetic gear 605 is sleeved and installed outside the triangular magnetic plate 607 fixed to the motor 604. The triangular magnetic plate 607 and the magnetic gear 605 repel each other. The magnetic gear 605, which is magnetically levitated and inserted outside the triangular magnetic plate 607, meshes with the drive gear 606 to realize the drive gear 606 when floating up and down.

[0024] During operation, the motor 604 is fixedly mounted on the guide frame 603, providing core power for the entire drive system. The guide frame 603 has through holes at the bottom for the solder wire to pass through and be guided.

[0025] Several guide components are evenly arrayed around the through hole. Each guide component includes a spring telescopic rod 608 fixedly installed inside the guide frame 603. A support plate 609 is fixedly connected to the upper part of the spring telescopic rod 608. A guide wheel 610 is rotatably installed on one side of the support plate 609. The guide wheel 610 extends into the through hole. When the solder wire passes through the through hole, it can be guided by the guide wheel 610, thereby avoiding the solder wire from getting stuck or worn due to excessive frictional resistance.

[0026] Meanwhile, the drive gear 606 is rotatably mounted on the support plate 609 of one of the guide members. Driven by the motor 604, it can generate an active driving effect with the solder wire to ensure stable wire feeding.

[0027] Because the spring telescopic rod 608 in the guide has elastic telescopic characteristics, it can automatically adapt to different solder wire diameters through the extension and retraction of the spring, so that the solder wire can be stably guided and fed in regardless of its thickness.

[0028] Furthermore, a triangular magnetic plate 607 is fixed outside the motor 604, and a magnetic gear 605 is sleeved on the outside of the triangular magnetic plate 607. The two are connected by magnetic repulsion to form a magnetic levitation connection, so that the magnetic gear 605 can be in a floating state. The magnetic gear 605 meshes with the drive gear 606. When the motor 604 is running, the magnetic gear 605 can still stably drive the drive gear 606 to rotate while floating up and down, thereby realizing the continuous and stable feeding of solder wire and flexible drive.

[0029] The working principle of this utility model is as follows: By fixing the welding pipe 4 on the support base 1, it can be integrated and linked with the CNC robot, thereby realizing the automated operation of welding. The end of the welding pipe 4 is provided with a wire assembly 6, which includes a sleeve 601 structure. The lower part of the sleeve 601 is specially opened with a through hole for the solder wire to pass through, so that the solder wire can be accurately fed into the welding point along a fixed path. A drive gear 606 is rotatably installed on the outside of the sleeve 601. The drive gear 606 is connected to a motor 604 fixed on the sleeve 601. When the motor 604 runs, it drives the drive gear 606 to rotate. The lower part of the drive gear 606 is located inside the through hole, which can stably drive and guide the solder wire passing through. With this structure, the feeding speed and direction of the solder wire are precisely controlled by the motor 604, eliminating the need for manual hand operation, thereby ensuring the continuity and uniformity of the solder point feeding.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
