This application provides multiple adjustable support seats under the table body, which can be adjusted independently, effectively improving the adjustment effect. When deformation occurs, the adjustable support seats can be adjusted accordingly according to the deformation position, thereby reducing the situation of further deformation of the table body.

[0031] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.
[0032] A nitriding furnace deformation treatment system, such as Figure 1 and Figure 2 As shown, it includes a table body 1, on which a nitriding furnace is placed, and a plurality of adjustable support seats 2 are provided at the bottom of the table body 1. The adjustable support seats 2 are arranged at equal intervals along the circumference of the table body 1. The adjustable support seats 2 include a base 21, on which an adjusting screw 22 is threadedly connected. When the adjusting screw 22 is rotated, it can move up and down. A ceramic block 221 is fixedly provided at one end of the adjusting screw 22 close to the table body 1. The ceramic block 221 is used to abut the table body 1. In specific implementation, the ceramic block 221 has good corrosion resistance and heat resistance. Even in a high-temperature environment, it is difficult to deform. Therefore, by supporting with the ceramic block 221, the stability of the support can be improved and the deformation of the support due to high temperature can be reduced.
[0033] like Figure 1 and Figure 2 As shown, the base 21 is also provided with a worm gear 23 and a worm 24. The worm gear 23 is rotationally connected to the base 21, and the worm gear 23 is threadedly connected to the lead screw. The worm gear 23 and the worm 24 are transmission-connected. The worm 24 can drive the worm gear 23 to rotate, and when the worm gear 23 rotates, it can drive the lead screw 32 to move up and down. The base 21 is also provided with a drive motor 25 corresponding to the worm 24. The rotating shaft of the drive motor 25 is fixedly connected to the worm 24. The drive motor 25 can drive the worm 24 to rotate, thereby driving the worm gear 23 to rotate. In specific implementation, the drive method of the worm gear 23 and the worm 24 is similar to the principle of the screw elevator in the prior art. The worm gear 23 and the worm 24 are threadedly driven. Since the worm gear 23 can only rotate, the lead screw will move up and down when the worm gear 23 moves. This achieves lifting motion.
[0034] like Figure 2 and Figure 3As shown, an adjustment platform 3 is also provided at the bottom of the platform 1. A plurality of movable grooves 31 are provided on the adjustment platform 3. The movable grooves 31 are arranged at equal intervals around the central axis of the adjustment platform 3. The movable grooves 31 correspond to the number and position of the adjustable support base 2. The base 21 of the adjustable support base 2 is slidably connected in the movable grooves 31 and can slide along the movable grooves 31. A driving screw 32 is provided in each movable groove 31. The driving screw 32 is rotatably connected to the adjustment platform 3. Each driving screw 32 is threadedly connected to the base 21 of the corresponding adjustable support base 2. When the driving screw 32 rotates, it can drive the base 21 to move along the movable groove 31. In a specific implementation, the driving screw 32 can drive the adjustable support base 2 as a whole to move along the movable groove 31, thereby adjusting different positions of the platform 1, further improving the accuracy of the adjustment, and being able to adjust the deformation at different positions.
[0035] like Figure 2 and Figure 3 As shown, a mounting slot 33 is provided in the middle of the adjustment platform 3. The mounting slot 33 is connected to each of the movable slots 31. A stepper motor 331 and a rotary motor 332 are provided in the mounting slot 33. The rotating shaft of the rotary motor 332 is fixedly connected to the stepper motor 331. The stepper motor 331 can rotate along the center of the adjustment platform 3. The rotating shaft of the stepper motor 331 can rotate clockwise and counterclockwise. A mating piece 34 is provided on the rotating shaft of the stepper motor 331. The mating piece 34 can achieve a detachable transmission connection with the drive screw 32. In a specific implementation, the rotary motor 332 can align the rotating shaft of the stepper motor 331 with different drive screws 32 respectively. After alignment, the drive screw 32 can be step-driven by rotating the stepper motor 331. This driving method can more accurately align the adjustable support base 2 with the position to be adjusted.
[0036] like Figure 2 and Figure 3 As shown, the mating member 34 includes a mating block 341. A mating groove 321 is provided on the drive screw 32 corresponding to the mating block 341. A clearance groove 322 is provided on the drive screw 32 corresponding to the rotating shaft of the stepping motor 331. The mating groove 321 and the clearance groove 322 are both provided through the drive screw 32. The mating block 341 can be embedded in the mating groove 321 and abut against the groove wall of the mating groove 321. When the mating block 341 rotates, it can drive the drive screw 32 to rotate. In a specific implementation, when the mating block 341 rotates, it will be restricted by the groove wall of the mating groove 321 on the drive screw 32, thereby driving the drive screw 32 to rotate together. Since the stepping motor 331 works step by step, the mating block 341 will be in the same position each time it completes its work, and can be aligned with the mating groove 321 without further adjustment.
[0037] like Figure 2 and Figure 3As shown, the adjustment platform 3 is further fixedly provided with a limit ring 35 on the upper side of the movable groove 31. The limit ring 35 is arranged near one side of the mounting groove 33 and is capable of abutting the base 21. A movable track 351 is provided on the limit ring 35. A deformation sensor 352 is slidably provided on the movable track 351. The deformation sensor 352 is used to collect deformation data of the platform body 1 and is capable of sliding along the movable track 351. A connecting rod 353 is provided between the deformation sensor 352 and the stepping motor 331. One end of the connecting rod 353 is hinged to the deformation sensor 352, and the other end of the connecting rod 353 is hinged to the stepping motor 331. During specific implementation, the limit ring 35 can limit the displacement of the adjustable support seat 2, reducing the situation where the adjustable support seat 2 moves into the installation groove 33 to form interference, and the deformation sensor 352 on the limit ring 35 uses a camera to collect the deformation situation, and moves the adjustable support seat 2 to the corresponding position and supports it upward according to the deformation situation. When multiple deformations appear in the same direction of the moving groove 31, the position with the most serious deformation is supported first, and then the other positions are supported in turn. It can effectively handle the deformation situation in a timely manner and reduce further deformation of the furnace.
[0038] Working principle: A plurality of adjustable support seats 2 are arranged on the lower side of the platform body 1. The adjustable support seats 2 support the deformed position of the platform body 1, which can effectively solve the problem of deformation of the platform body 1, and through deformation detection and corresponding adjustment, the deformation position can be more effectively and accurately adjusted.
[0039] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
