[0014] This invention provides a welding device for processing turbine blade assembly diaphragms. It has the following advantages: 1. This welding equipment for processing turbine blade assembly partitions includes a support platform. A fourth drive motor rotates the support platform, and a first air pump is activated to cause welding slag from the top of the support platform to fall onto the surface of an annular slider. Under gravity, the slag falls onto the surface of the guide slider, preventing it from accumulating on the top of the support platform and the blade surface. This facilitates subsequent slag collection and improves the welding efficiency. Furthermore, a second air pump is installed on the surface of the annular slider. Activating the second air pump allows the annular slider to continuously absorb welding fumes, preventing fine fumes from accumulating on the structural surface and causing processing difficulties, thus further improving the welding efficiency.

[0015] 2. The welding equipment for processing turbine blade assembly partitions is equipped with a brush block. When the fourth drive motor is started, the brush block is rotated to clean the through hole of the annular slider. The fixed scraper scrapes off the welding slag on the surface of the annular slider, which prevents the welding slag from sticking to the surface of the annular slider when the support platform is thrown off for cleaning, thus avoiding the welding slag from sticking to the inner wall of the annular slider.

[0016] 3. This welding equipment for processing turbine blade assembly partitions, by setting up a vibrating scraper, starts the fourth drive motor to drive the support platform to rotate, which in turn drives the vibrating scraper to rotate as well. When the vibrating scraper passes the limit block, it drives the guide slider to vibrate inside the second fixed block, so that the welding slag on the surface of the guide slider falls quickly into the inside of the collection box and is collected, preventing the welding slag from sticking to the inside of the guide slider. At the same time, the vibrating scraper scrapes off the welding slag on the inner wall of the fixed scraper while rotating, ensuring that the welding slag falls completely into the inside of the collection box, preventing the welding slag from getting stuck in the structure and affecting the processing efficiency of the equipment.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0021] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a welding device for processing turbine blade assembly partitions, including a support base 1, a collection box 8 fixedly connected to the bottom of the support base 1, a welding mechanism 2 fixedly connected to the surface of the support base 1, the welding mechanism 2 including a third sliding support plate 26, a fourth sliding support plate 3 fixedly connected inside the third sliding support plate 26, an air blowing mechanism 4 fixedly connected to the top of the fourth sliding support plate 3, a dust suction and baffle mechanism 7 slidably connected inside the support base 1, a support mechanism 5 fixedly connected inside the support base 1, the support mechanism 5 including a second fixing block 55, and a vibration mechanism 6 slidably connected inside the second fixing block 55; Vibration mechanism 6 includes: Vibrating scraper 61 is fixedly connected to the surface of support platform 53; Guide slider 62 is fixedly connected to the top of support slider 63; The dust extraction barrier mechanism 7 includes an annular slider 72, which is slidably connected inside the support base 1.

[0022] The welding mechanism 2 includes a first sliding support plate 21, which is fixedly connected to the surface of the support base 1. A first drive motor 22 is fixedly connected to the top of the first sliding support plate 21. A second sliding support plate 23 is slidably connected inside the first sliding support plate 21. A second drive motor 24 is fixedly connected to the surface of the second sliding support plate 23. A third sliding support plate 26 is slidably connected inside the second sliding support plate 23. A third drive motor 25 is fixedly connected to the surface of the third sliding support plate 26.

[0023] The air blowing mechanism 4 includes a first air pump 41, which is fixedly connected to the top of the fourth sliding support plate 3, and a welding head is fixedly connected to the bottom of the fourth sliding support plate 3. A connecting pipe 42 is fixedly connected inside the first air pump 41.

[0024] The support mechanism 5 includes a first fixing block 52, which is fixedly connected to the surface of a second fixing block 55. A fourth drive motor 54 is fixedly connected inside the first fixing block 52. A support platform 53 is fixedly connected inside the fourth drive motor 54 through its output shaft. An electromagnet 51 is fixedly connected inside the support platform 53.

[0025] The dust extraction barrier mechanism 7 includes a fifth drive motor 74, which is fixedly connected inside the support base 1. A first gear 75 is fixedly connected inside the fifth drive motor 74 via an output shaft. A ring rack 76 is meshed with the surface of the first gear 75. A second rack 77 is meshed with the surface of the ring rack 76. A threaded rod 78 is fixedly connected to the top of the second rack 77. A support slider 79 is slidably connected to the surface of the threaded rod 78.

[0026] In use, the workpiece is placed on top of the support platform 53. Then, the electromagnet 51 is activated to fix the workpiece on top. Next, the first drive motor 22 is activated, and the output shaft drives the second sliding support plate 23 to adjust its height. Then, the second drive motor 24 is activated, and the output shaft drives the third sliding support plate 26 to adjust its horizontal position. Then, the third drive motor 25 is activated, and the output shaft adjusts the welding head set at the bottom of the fourth sliding support plate 3 to a suitable position. Then, the connecting pipe 42 is activated to continuously blow air onto the surface of the workpiece to prevent impurities such as oxide scale on the workpiece surface from causing porosity at the weld. The fifth drive motor 74 is activated, and the output shaft drives the first gear 75 to rotate. The rotation of the first gear 75 drives the ring rack 76 to rotate. The rotation of the ring rack 76 drives the second rack 77 to rotate. The rotation of the second rack 77 drives the threaded rod 78 to rotate. The rotation of the threaded rod 78 drives the support slider 79 to move towards the top of the support base 1, thereby moving the ring slider 72 along with it. At the same time, the second air pump 71 is activated to facilitate welding.

[0027] A support platform 53 is set up, and the fourth drive motor 54 is started to drive the support platform 53 to rotate. In conjunction with the start of the first air pump 41, the welding slag on the top of the support platform 53 falls onto the surface of the annular slider 72. Under the action of gravity, it falls into the surface of the guide slider 62, which prevents the welding slag from accumulating on the top of the support platform 53 and the surface of the blades. This facilitates the subsequent collection of welding slag and improves the welding efficiency of the equipment. In addition, a second air pump 71 is set on the surface of the annular slider 72. Activating the second air pump 71 allows the annular slider 72 to continuously absorb the welding fumes, preventing the accumulation of fine fumes on the structural surface and causing the equipment to be unable to process normally, thereby further improving the welding efficiency of the equipment.

[0028] Example 2: Please refer to Figure 1-10 Based on Embodiment 1, the present invention provides a technical solution: The surface of the annular slider 72 is fixedly connected to the second air pump 71, the inside of the support base 1 is fixedly connected to the fixed scraper 73, and the second fixed block 55 is fixedly connected to the surface of the fixed scraper 73.

[0029] The vibration mechanism 6 includes a vibrating scraper 61, which is fixedly connected to the surface of the support platform 53. An arc-shaped through hole is provided at the bottom of the vibrating scraper 61, and a brush block 65 is fixedly connected to the top of the vibrating scraper 61.

[0030] The support slide rod 63 is slidably connected inside the second fixed block 55. A spring is fixedly connected to the surface of the support slide rod 63 and the spring is fixedly connected to the second fixed block 55. A limit block 64 is fixedly connected to the top of the guide slider 62, and a protrusion is provided on the top of the limit block 64 that matches the size of the through hole opened at the bottom of the vibrating scraper 61.

[0031] In use, after welding is completed, the fourth drive motor 54 is started, which drives the support platform 53 to rotate through the output shaft. While the support platform 53 rotates, the connecting pipe 42 continues to blow air towards the top of the support platform 53. Then, some welding slag hits the inner wall of the annular slider 72 and slides down to the surface of the guide slider 62, while some welding slag falls directly into the collection box 8 for collection. While the support platform 53 rotates, it drives the vibrating scraper 61 to rotate. When the vibrating scraper 61 rotates, it periodically hits the limiting block 64, which causes the guide slider 62 to vibrate periodically, so that the welding slag on the top of the guide slider 62 falls completely into the collection box 8. At the same time, the vibrating scraper 61 rotates, which drives the brush block 65 to continuously brush the inner wall of the annular slider 72. Then, the fifth drive motor 74 is started, which drives the annular slider 72 to move towards the bottom of the support base 1 through gear meshing. This allows the brush block 65 to brush and, together with the fixed scraper 73, scrape the inner wall of the annular slider 72, ensuring that the welding slag is completely collected.

[0032] When the brush block 65 is set up, the fourth drive motor 54 is started, and the brush block 65 is rotated to clean the through hole of the annular slider 72. In addition, the fixed scraper 73 scrapes off the welding slag on the surface of the annular slider 72, so as to avoid the welding slag sticking to the surface of the annular slider 72 when the support platform 53 is thrown off for cleaning, which affects the cleaning of the welding slag, thereby preventing the welding slag from sticking to the inner wall of the annular slider 72.

[0033] When a vibrating scraper 61 is installed, the fourth drive motor 54 is started to drive the support platform 53 to rotate, which in turn drives the vibrating scraper 61 to rotate as well. When the vibrating scraper 61 passes the limit block 64, it will drive the guide slider 62 to vibrate inside the second fixed block 55, so that the welding slag on the surface of the guide slider 62 will fall quickly into the collection box 8 and be collected, thus preventing the welding slag from sticking to the inside of the guide slider 62. At the same time, the vibrating scraper 61 will scrape off the welding slag on the inner wall of the fixed scraper 73 while rotating, ensuring that the welding slag falls completely into the collection box 8, thus preventing the welding slag from getting stuck in the structure and affecting the processing efficiency of the equipment.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
