Technical Field

[0001] This utility model relates to the technical field of welding device for turbine machining, specifically a welding device for turbine machining. Background Technology

[0002] As a core component of power machinery, the performance of the turbine directly determines the efficiency, reliability, and lifespan of the entire machine. Welding, as a key process in turbine manufacturing, places extremely high demands on welding precision, heat-affected zone control, and joint performance.

[0003] Chinese Patent CN212330012U discloses a welding device for turbine machining, comprising a welding apparatus; the welding apparatus includes a turbine support ring assembly mounted on a welding table, a fixed-point rotating horizontal plate mounted on the welding table via a support frame, and two laser welding heads vertically downwards at the bottom of the fixed-point rotating horizontal plate via a welding cylinder; it also includes a semi-enclosed turbine, which is concentrically welded from an upper cover plate, a turbine, and a lower cover plate, which are sequentially inverted and concentrically placed on the turbine support ring assembly, ensuring that the welding end face of the semi-enclosed turbine remains horizontal and upwards; a servo reduction motor is mounted on the support frame to drive the fixed-point rotating horizontal plate to rotate; the two laser welding heads correspond to the two circular welding contours of the semi-enclosed turbine, respectively. This invention can simultaneously perform fixed-point rotating laser welding on the two circular welding contours of the semi-enclosed turbine, achieving high welding efficiency.

[0004] The aforementioned patent has some shortcomings: when welding turbines in the existing technology, the different turbine components are height-adjusted by multiple cylinders, making it difficult to keep the extension and retraction amplitudes of the cylinders on both sides precisely synchronized, which can easily lead to the problem of tilting on both sides when the turbine components are raised and lowered.

[0006] To solve the above-mentioned technical problems, this utility model provides a welding device for turbine processing, including a support platform, a support frame fixedly connected to the top of the support platform, a cylinder fixedly installed on the top of the support frame, a lifting platform fixedly connected to the bottom of the cylinder, a limit rod fixedly connected to the top of the lifting platform, a first lifting frame movably sleeved at the bottom of the support platform, a first positioning sleeve fixedly connected to the top of the first lifting frame, a first threaded rod threaded into the internal thread of the first lifting frame, a second lifting frame movably sleeved inside the support platform, a second positioning sleeve fixedly connected to the top of the second lifting frame, a second threaded rod threaded into the internal thread of the second lifting frame, a third lifting frame movably sleeved inside the support platform, a third positioning sleeve fixedly connected to the top of the third lifting frame, a third threaded rod threaded into the internal thread of the third lifting frame, an adjustment mechanism provided at the bottom of the lifting platform, and a moving mechanism provided at the bottom of the support platform.

[0010] Preferably, the moving mechanism includes a support column, which is fixedly connected to the bottom of the support platform, and a sliding wheel is installed at the bottom of the support column.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This welding device for turbine processing, by setting a first threaded rod, when multiple turbine components need to be positioned and fixed, the first threaded rod is rotated, so that the first threaded rod can drive the first positioning sleeve to move up and down through the first lifting frame. At this time, the second threaded rod is rotated, so that the second threaded rod can drive the second positioning sleeve to move up and down stably through the second lifting frame. This achieves a stable height adjustment effect for multiple turbine components, avoiding the problem of tilting and offset during turbine component height adjustment, which would lead to large errors in the welding accuracy of turbine components, thereby improving the welding accuracy of turbine components.

[0019] Please see Figure 1-3 This utility model provides an embodiment of a welding device for turbine processing, comprising a support platform 1, a support frame 2 fixedly connected to the top of the support platform 1, a cylinder 3 fixedly mounted on the top of the support frame 2, a lifting platform 4 fixedly connected to the bottom of the cylinder 3, a limit rod 5 fixedly connected to the top of the lifting platform 4, a first lifting frame 6 movably sleeved at the bottom of the support platform 1, a first positioning sleeve 7 fixedly connected to the top of the first lifting frame 6, a first threaded rod 8 threadedly sleeved inside the first lifting frame 6, a second lifting frame 9 movably sleeved inside the support platform 1, a second positioning sleeve 10 fixedly connected to the top of the second lifting frame 9, a second threaded rod 11 threadedly sleeved inside the second lifting frame 9, a third lifting frame 12 movably sleeved inside the support platform 1, a third positioning sleeve 13 fixedly connected to the top of the third lifting frame 12, a third threaded rod 14 threadedly sleeved inside the third lifting frame 12, an adjustment mechanism 15 provided at the bottom of the lifting platform 4, and a moving mechanism 16 provided at the bottom of the support platform 1.

[0020] The first threaded rod 8 is movably sleeved inside the second lifting frame 9, and the first threaded rod 8 is located directly below the support platform 1. By setting the first threaded rod 8, when multiple turbine components need to be positioned and fixed, rotating the first threaded rod 8 allows the first threaded rod 8 to drive the first positioning sleeve 7 to move up and down through the first lifting frame 6. At this time, rotating the second threaded rod 11 allows the second threaded rod 11 to drive the second positioning sleeve 10 to move up and down stably through the second lifting frame 9. This achieves a stable height adjustment effect for multiple turbine components, avoiding the problem of tilting and offset during turbine component height adjustment, which could lead to large errors in the welding accuracy of turbine components, thereby improving the welding accuracy of turbine components.

[0021] The limiting rod 5 is movably sleeved inside the support frame 2, and there are four limiting rods 5. By setting the limiting rods 5, when the turbine components need to be welded, the cylinder 3 is activated, so that the cylinder 3 can drive the lifting platform 4 to move up and down. At this time, the limiting rods 5 can limit the up and down movement of the lifting platform 4, so as to avoid the problem of tilting and deviation of the lifting platform 4 when it is raised and lowered, thereby improving the stability of the lifting platform 4 when it is raised and lowered.

[0022] The adjusting mechanism 15 includes a worm gear reducer 151, which is fixedly installed at the bottom of the lifting platform 4. A rotating arm 152 is fixedly sleeved on the output shaft of the worm gear reducer 151, and a laser welding head 153 is fixedly installed on one side of the bottom of the rotating arm 152. By setting the adjusting mechanism 15, when welding the turbine component, the worm gear reducer 151 is started, so that the worm gear reducer 151 drives the laser welding head 153 to rotate through the rotating arm 152, so that the laser welding head 153 can perform circumferential welding on the turbine component, thereby improving the welding speed of the turbine component.

[0023] The moving mechanism 16 includes a support column 161, which is fixedly connected to the bottom of the support platform 1. A sliding wheel 162 is installed at the bottom of the support column 161. By setting up the moving mechanism 16, when the welding device needs to be moved and transported, the support platform 1 is pushed, so that the sliding wheel 162 can drive the support platform 1 to move horizontally through the support column 161, that is, drive the support frame 2 to move horizontally, thereby achieving the effect of moving and transporting the welding device, and thus bringing convenience to the adjustment of the working position of the welding device.

[0024] Working principle: When multiple turbine components need to be positioned and fixed, rotating the first threaded rod 8 allows the first positioning sleeve 7 to move up and down via the first lifting frame 6. Simultaneously, rotating the second threaded rod 11 allows the second positioning sleeve 10 to move stably up and down via the second lifting frame 9. This achieves stable height adjustment for multiple turbine components, preventing tilting or offset during height adjustment and thus avoiding significant errors in welding accuracy. When turbine component welding is required, cylinder 3 is activated, causing the lifting platform 4 to move up and down. The limit rod 5 then limits the movement of the lifting platform 4, preventing it from tilting further. The problem of tilting and deviation during descent is addressed, thereby improving the stability of the lifting platform 4 during lifting. When welding turbine components, the worm gear reducer 151 is activated, allowing the worm gear reducer 151 to drive the laser welding head 153 to rotate via the rotating arm 152. This enables the laser welding head 153 to perform circumferential welding on the turbine components, thereby increasing the welding speed of the turbine components. When the welding device needs to be moved and transported, the support platform 1 is pushed, allowing the sliding wheel 162 to drive the support platform 1 to move horizontally via the support column 161, which in turn drives the support frame 2 to move horizontally, thus achieving the effect of moving and transporting the welding device. This also facilitates the adjustment of the working position of the welding device. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
