[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8One embodiment of the present invention is: a special tooling for heat treatment of wind turbine yaw gear shafts, including a lower end plate 1, a limiting ring 2 fixedly connected to the upper surface of the lower end plate 1, the lower end plate 1 for supporting the gear shaft, a central support column 5 snapped onto the inner surface of the limiting ring 2, an upper end plate 3 fixedly connected to the top of the central support column 5, the limiting ring 2 and the central support column 5 for quick docking of the lower end plate 1 and the upper end plate 3, a mounting column 4 fixedly connected to the lower surface of the upper end plate 3, the upper end plate 3 for supporting the gear shaft, and a modular assembly device 6 disposed below the upper end plate 3, the modular assembly device 6 for... The device is modularly installed and disassembled. Portable devices 7 are located on both sides of the upper end plate 3, facilitating various movements of the device. Inserting the mounting post 4 into the slot 8 makes the upper end plate 3 more stable. Multiple gear shafts are then inserted into the upper end plate 3 and lower end plate 1, and the gear shafts are lifted into the heating device via the lower end plate 1, allowing for simultaneous heat treatment of multiple gear shafts and improving processing efficiency. The casters 11 are quickly installed below the lower end plate 1, facilitating movement of the device within a small area. The lower end plate 1 includes slots 8, which are formed on the lower end plate 1. On the surface, the clamping rail 9 is fixedly connected to both sides of the lower surface of the lower end plate 1. The inner surface of the clamping rail 9 is engaged with the support 10. The lower surface of the support 10 is hinged with the universal wheel 11. The support 10 and the universal wheel 11 are used for the device to move on the ground. The lower end plate 1 also includes a second slot 12, which is opened on the front and rear sides of the upper surface of the support 10. The abutment rod 13 slides through the bottom of the inner surface of the first slot 8 and extends out of the lower surface of the lower end plate 1. The bottom end of the abutment rod 13 is fixedly connected to the locking shaft 14. The magnetic suction convex shaft 17 is fixedly connected to the side surface of the support 10. The inner surface of the magnetic suction convex shaft 17 is slidably connected to the fixing rod 11. 5. A magnetic sleeve shaft 16 is fixedly connected to the end of the fixing rod 15 away from the support 10. The inner surface of the mounting column 4 and the limiting ring 2 abuts. The bottom end of the central support column 5 abuts with the upper surface of the lower end plate 1. The bottom end of the mounting column 4 is engaged with the inner surface of the slot 1 8. The upper surface of the support 10 abuts with the lower surface of the lower end plate 1. The inner surface of the slot 14 is engaged with the inner surface of the slot 2 12. The magnetic sleeve shaft 16 and the magnetic convex shaft 17 are sleeved on the circumferential surface. The fixing rod 15 slides through the side of the support 10 near the magnetic convex shaft 17 and penetrates into the inner surface of the slot 2 12. A through hole 1 is opened on the inner side of the slot 14, and the inner surface of the through hole 1 and the slot 2 12 are engaged. The fixing rod 15 is snapped in place, and a spring is provided between the top of the clamping shaft 14 and the lower surface of the lower end plate 1, which improves the overall processing efficiency of the gear shaft. The clamping shaft 14 can limit the support 10 to prevent it from falling off the clamping rail 9 during movement, thus improving the stability of movement and facilitating the transfer of the gear shaft in the processing workshop. Releasing the limit on the support 10 and removing it from the clamping rail 9 facilitates tooling and heat treatment.

[0024] Working principle: The upper end plate 3 is inserted into the limiting ring 2 via the mounting column 4 and the central support column 5, thereby quickly connecting the upper end plate 3 and the lower end plate 1, which assists in the installation of the device. After the mounting column 4 is inserted into the slot 8, the upper end plate 3 becomes more stable. At this time, multiple gear shafts are inserted into the upper end plate 3 and the lower end plate 1, and then the gear shafts are lifted into the heating device through the lower end plate 1, which facilitates the simultaneous heat treatment of multiple gear shafts and improves the processing efficiency. The support 10 is inserted into the clamping rail 9, which allows the universal wheel 11 to be quickly installed under the lower end plate 1, which facilitates the transfer of the device within a small range and improves the overall processing efficiency of the gear shafts. After the mounting column 4 is inserted into the slot 8, the abutment rod 13 is pressed down, and the abutment rod 13 drives the clamping shaft 14 to move down and insert into the slot 12. At this time, the magnetic sleeve shaft 1 is... Pushing the magnetic sleeve 16 towards the side closer to the support 10, the magnetic sleeve 16 contacts the magnetic convex shaft 17 and is fixed to its outer surface by magnetic force. When the magnetic sleeve 16 approaches the support 10, it drives the fixing rod 15 to slide in the magnetic convex shaft 17 and insert into the through hole 1 in the clamping shaft 14, thereby locking the clamping shaft 14 in the support 10. The clamping shaft 14 can limit the support 10 to prevent it from falling off the clamping rail 9 during movement, improving the movement stability and facilitating the transfer of the gear shaft in the processing workshop. When the lower end plate 1 drives the gear shaft to move outside the heating device, the fixing rod 15 is pulled away from the support 10. At this time, the mounting column 4 and the clamping shaft 14 can be pulled away from the clamping slot 8 and the clamping slot 12 respectively, thereby releasing the limitation on the support 10 and removing it from the clamping rail 9, which is convenient for tooling and heat treatment.

[0025] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the module assembly device 6 includes a second fixing rod 63, which slides through the front and rear sides of the lower end plate 1 and penetrates into the inner surface of the slot 8. A pull rod 66 is fixedly connected to the end of the second fixing rod 63 away from the mounting post 4. A sliding ring 65 is fixedly connected to the circumferential surface of the second fixing rod 63. The second fixing rod 63 is inserted into the slot 8 and the through hole 2 at the bottom of the mounting post 4, thereby locking the mounting post 4 and the lower end plate 1, improving the installation stability of the device, and making the gear shaft more stable during heat treatment. The mounting post 4 is then pulled out from the slot 8 and the limiting ring 2, thereby separating the upper end plate 3 and the lower end plate 1, facilitating the disassembly of the gear shaft. The module assembly device 6 also includes a housing 64, which is fixedly connected to the front and rear sides of the lower end plate 1. An L-shaped connecting rod 61 is fixedly connected to the circumferential surface of the contact rod 13. A connecting rod 67 is fixedly connected to the top of the L-shaped connecting rod 61. An extension groove 62 is opened on the upper surface of the lower end plate 1. A second spring is provided between the sliding ring 65 and the lower end plate 1. The circumferential surface of the sliding ring 65 is slidably connected to the inner surface of the sleeve 64. The second fixed rod 63 is slidably connected to the inner surface of the end of the sleeve 64 away from the lower end plate 1. A second through hole is opened at the bottom of the mounting column 4, and the inner surface of the second through hole is engaged with the second fixed rod 63. The extension groove 62 is connected to the first slot 8. The contact rod 13 springs up and resets. Then, the device can be quickly disassembled by simply pulling the pull rod 66, which improves the ease of use. The L-shaped connecting rod 61 drives the contact rod 13 to move upward and push the mounting column 4 out of the first slot 8, which further improves the ease of use of the device.

[0026] Working principle: Pulling the pull rod 66 away from the lower end plate 1 causes the second fixing rod 63 to be pulled out of the slot 8. At this time, the mounting post 4 is inserted into the slot 8. Then, the pull rod 66 is released. Subsequently, the elastic force of the second spring pulls the sliding ring 65 to slide within the housing 64 and approach the lower end plate 1. The sliding ring 65 then drives the second fixing rod 63 to be inserted into the slot 8 and the through hole 2 at the bottom of the mounting post 4, thereby locking the mounting post 4 and the lower end plate 1, improving the installation stability of the device, and making the gear shaft more stable during heat treatment. After the treatment is completed, pull the pull rod 66 away from the lower end plate 1 again. The pull rod 66 causes the second fixing rod 63 to be pulled out of the through hole 2 and into the slot 8. Unlocking the mounting post 4 allows it to be pulled out of the slot 8 and the limiting ring 2, thus separating the upper plate 3 and the lower plate 1 for easy disassembly of the gear shaft. The spring 1, via the retaining shaft 14, causes the contact rod 13 to spring upwards and reset. Pulling the lever 66 then allows for quick disassembly of the device, improving ease of use. If the mounting post 4 is too tightly secured, simply use your finger to push the connecting rod 67 upwards. The connecting rod 67 causes the L-shaped connecting rod 61 to slide upwards within the extension groove 62. The L-shaped connecting rod 61 then moves the contact rod 13 upwards, pushing the mounting post 4 out of the slot 8, further enhancing the ease of use of the device.

[0027] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the portable device 7 includes a mounting plate 71, which is disposed on both sides of the upper end plate 3. A positioning rod 75 is fixedly connected to the lower surface of the mounting plate 71, a locking rod 72 is fixedly connected to the side surface of the mounting plate 71, a support plate 76 is fixedly connected to both sides of the upper surface of the lower end plate 1, and a fixing rod 77 is slidably connected to the inner surfaces of the front and rear sides of the support plate 76. A limiting shaft 73 is inserted into the mounting plate 71 to make the mounting plate 71 more stable. The fixing rod 77 is inserted into the through hole 3 opened at the bottom of the positioning rod 75 to make the mounting plate 71 quickly locked. The locking rod 72 is hooked by a crane and the device is lifted, which facilitates the transportation of tooling and gear shaft to the heating device inlet at different heights, improving the applicability of the device. The portable device 7 also includes a limiting shaft 73, which is fixedly connected to the outer surface of the upper end plate 3. A card seat 74 is fixedly connected to both sides of the upper surface of the lower end plate 1, and a gripping plate 78 is fixedly connected to the fixing rod 77. At the end furthest from the card holder 74, a slot 710 is formed on the circumferential surface of the fixing rod 77. A card plate 79 is engaged with the inner surface of the slot 710. The positioning rod 75 slides through the lower surface of the upper end plate 3 from the upper surface. The bottom end of the positioning rod 75 abuts against the upper surface of the lower end plate 1. A through hole 3 is formed at the bottom of the positioning rod 75, and the inner surface of the through hole 3 engages with the fixing rod 77. The positioning rod 75 engages with the inner surface of the card holder 74, and the fixing rod 77 slides from the side surface of the card holder 74. The plate 79 penetrates the inner surface of the card holder 74 and is fixedly connected to the lower surface of the connecting rod 67. Pulling the locking rod 72 can improve the convenience of transporting the device on the ground. The fixing rod 77 slides in the support plate 76 and is inserted between the card holder 74 and the positioning rod 75, making the installation more stable. The card holder 79 is inserted into the slot 710, so that the fixing rod 77 is locked while the upper end plate 3 is installed, which further improves the stability of the mounting plate 71 and the locking rod 72 and the convenience of using the device.

[0028] Working principle: The positioning rod 75 is quickly installed by inserting it into the upper end plate 3. Then, the mounting plate 71 is aligned with the limiting shafts 73 on both sides of the upper end plate 3 and connected, allowing the limiting shafts 73 to insert into the mounting plate 71, making the mounting plate 71 more stable. After the bottom end of the positioning rod 75 contacts the lower end plate 1, the fixing rod 77 is inserted into the through hole 3 at the bottom of the positioning rod 75, quickly locking the mounting plate 71. After installing the mounting plate 71 and locking rod 72 onto the upper end plate 3, a crane can hook the locking rod 72 and lift the device, facilitating the transportation of the tooling and gear shaft to the heating device inlet at different heights, improving the device's applicability. Furthermore, pulling the locking rod 72 can lift the device for rotation on the ground. For ease of use, after inserting the positioning rod 75 into the upper end plate 3, push the gripping plate 78 to bring it close to and fit against the support plate 76. When the gripping plate 78 moves, it causes the fixing rod 77 to slide within the support plate 76 and insert between the card seat 74 and the positioning rod 75, making the installation more stable. At this time, insert the mounting post 4 into the card slot 8 and press the abutment rod 13 downward. The abutment rod 13 causes the L-shaped connecting rod 61 and the connecting rod 67 to move downward. The connecting rod 67 then causes the card plate 79 to move downward and insert into the slot 710 opened on the fixing rod 77, so that the fixing rod 77 is locked while the upper end plate 3 is installed, which further improves the stability of the mounting plate 71 and the locking rod 72 and the ease of use of the device.
