Abstract
Description
Technical Field
[0001] This utility model relates to the field of turbine shaft manufacturing technology, specifically a limiting device for turbine shaft manufacturing. Background Technology
[0002] The turbine shaft is a precision transmission component that requires positioning and support during machining, thus necessitating the use of a limiting device.
[0003] According to a published specification (CN217194818U) of a turbine shaft production limiting device, the aforementioned application achieves the phenomenon of supporting and limiting the turbine shaft body by squeezing two support wheels during the fall of the turbine shaft body. The two support wheels move outward and use gears to push the toothed plate upward. The toothed plate drives the limiting wheel to rise synchronously, which solves the problem that the existing limiting devices have relatively simple functions and structures and cannot achieve the effect of supporting and positioning the turbine shaft during the limiting process, which seriously affects the stability of the turbine shaft support and limiting. This method only supports the bottom of the turbine shaft, and the support direction is not only unidirectional, but it is also impossible to intuitively know whether the turbine shaft is in a fixed state during the fixing process. In response to this problem, we propose a limiting device for turbine shaft production. Utility Model Content
[0004] The purpose of this invention is to provide a limiting device for turbine shaft production to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting device for turbine shaft production, comprising a limiting platform, a support frame fixedly mounted on the surface of the limiting platform, and a control component disposed within the support frame, the control component comprising:
[0006] A limiting ring, wherein the retaining teeth within the limiting ring are used to increase friction;
[0007] A support plate, wherein the support plate is connected to a limiting ring via a telescopic rod;
[0008] The limiting component is used to limit the turbine shaft, so as to intuitively know whether the turbine shaft is fixed tightly and avoid loosening during the processing.
[0009] Preferably, the inner wall of the limiting ring is fixedly equipped with a locking tooth, the surface of the limiting ring is fixedly connected to one end of the telescopic rod, and the other end of the telescopic rod is fixedly installed on the surface of the support plate. When the limiting ring is abutted, the telescopic rod can be squeezed.
[0010] Preferably, the limiting member includes a knocking rod, which is fixedly installed on the surface of the limiting ring. The knocking rod passes through the support plate and is slidably connected to the support plate. When the limiting ring moves, the knocking rod can slide inside the support plate.
[0011] Preferably, the support plate is fixedly installed on the inner wall of the support frame, and a bell is fixedly installed on the inner wall of the support frame. When the bell rings, it can remind the operator to operate.
[0012] Preferably, a movable plate is fixedly installed on the surface of the support frame. The movable plate passes through the support frame and is slidably connected to the support frame. When the movable plate is subjected to force, it can drive the support frame to move laterally in sync.
[0013] Preferably, the movable plate is penetrated by a threaded rod and threadedly connected to the threaded rod. The threaded rod penetrates the support frame and is rotatably connected to the support frame. The surface of the support frame is rotatably connected to the surface of the turntable. The surface of the turntable is fixedly connected to the surface of the threaded rod. When the turntable drives the threaded rod to rotate, the movable plate can slide within the support frame under force.
[0014] Preferably, the surface of the turntable is hinged to the surface of the movable block, the surface of the movable block is fixedly connected to one side of the torsion spring, the other side of the torsion spring is fixedly installed on the surface of the turntable, a fixing ring is fixedly installed on the surface of the support frame, and a limit block is fixedly installed on the inner wall of the fixing ring. When the turntable rotates, the movable block can fold under the support of the torsion spring when it abuts against the surface of the limit block.
[0015] Compared with the prior art, the present invention provides a limiting device for turbine shaft production, which has the following advantages:
[0016] 1. This turbine shaft production limiting device, equipped with a control component, allows a turntable to be moved on the surface of the support frame. The turntable drives a threaded rod to rotate. When the threaded rod rotates, the moving plate is forced to move the support frame laterally. The support frame, connected to a limiting ring via a telescopic rod, moves synchronously towards the center of the limiting platform. When the limiting ring contacts the surface of the turbine shaft, it receives a reverse force from the turbine shaft. The turbine shaft then presses against the telescopic rod. The knocking rod fixed to the surface of the limiting ring slides within the support plate under force and strikes a bell. The bell rings, alerting the operator and providing a clear indication of whether the turbine shaft is securely fixed, thus preventing loosening during processing.
[0017] 2. The limiting device for turbine shaft production has a limiting component. When the turntable drives the threaded rod to rotate, the movable block hinged to the surface of the turntable will abut against the surface of the limiting block. The movable block can then be folded under the support of the torsion spring. Since there are multiple sets of limiting blocks, the rotation speed of the turntable and the threaded rod, as well as the moving speed of the moving plate, can be limited, thereby avoiding accidental pinching accidents caused by excessive moving speed.

Detailed Implementation
[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a limiting device for turbine shaft production, including a limiting platform 1, a support frame 2 fixedly installed on the surface of the limiting platform 1, and a control component 3 provided inside the support frame 2. The control component 3 includes: a limiting ring 31, a locking tooth 32, a telescopic rod 33, a support plate 34, and a limiting member 35. When the limiting ring 31 comes into contact with the surface of the turbine shaft, it will be subjected to the reverse contact force of the turbine shaft. The turbine shaft squeezes the limiting ring 31, and the limiting ring 31 simultaneously squeezes the telescopic rod 33. The telescopic rod 33 retracts, and the knocking rod 351 fixed to the surface of the limiting ring 31 slides within the support plate 34 under force, and knocks the bell 353. The bell 353 makes a sound to remind the operator, thereby intuitively understanding whether the turbine shaft is fixed tightly, and avoiding loosening during processing.
[0025] A retaining ring 31 has a retaining tooth 32 fixedly installed on its inner wall. The surface of the retaining ring 31 is fixedly connected to one end of the telescopic rod 33, and the other end of the telescopic rod 33 is fixedly installed on the surface of the support plate 34. When the retaining ring 31 is pressed, it can squeeze the telescopic rod 33. The retaining member 35 includes a knocking rod 351, which is fixedly installed on the surface of the retaining ring 31. The knocking rod 351 passes through the support plate 34 and is slidably connected to the support plate 34. When the retaining ring 31 moves, the knocking rod 351 can slide within the support plate 34. The support plate 34 is fixedly installed on the inner wall of the support frame 352. A bell 353 is fixedly installed on the inner wall of the support frame 352. When the bell 353 sounds, it can remind the operator to operate. A movable plate 354 is fixedly installed on the surface of the support frame 352. The movable plate 354 passes through the support frame 2 and is slidably connected to the support frame 2. When the movable plate 354 is subjected to force, it can drive the support frame 352 to move laterally synchronously. The movable plate 354 is threaded through and connected to the threaded rod 355. The threaded rod 355 passes through the support frame 2 and is rotatably connected to the support frame 2. The surface of the support frame 2 is rotatably connected to the surface of the turntable 356. The surface of the turntable 356 is fixedly connected to the surface of the threaded rod 355. When the turntable 356 drives the threaded rod 355 to rotate, the movable plate 354 can slide within the support frame 2 under force. The surface of the turntable 356 is hinged to the surface of the movable block 357. The surface of the movable block 357 is fixedly connected to one side of the torsion spring 358. The other side of the torsion spring 358 is fixedly installed on the surface of the turntable 356. A fixing ring 359 is fixedly installed on the surface of the support frame 2. A limit block 350 is fixedly installed on the inner wall of the fixing ring 359. When the turntable 356 rotates, the movable block 357 can fold under the support of the torsion spring 358 when it abuts against the surface of the limit block 350.
[0026] In this invention, when it is necessary to limit the turbine shaft, the turbine shaft is placed on the surface of the limiting platform 1. After placement, the turntable 356 is rotated on the surface of the support frame 2. The turntable 356 drives the threaded rod 355 to rotate within the support frame 2. During the rotation of the turntable 356, the movable block 357 hinged to the surface of the turntable 356 will abut against the surface of the limiting block 350. The movable block 357 can then fold under the support of the torsion spring 358. Since multiple sets of limiting blocks 350 are provided, the rotational speed of the turntable 356 and the threaded rod 355, as well as the moving speed of the moving plate 354, can be limited. During the lateral movement of the moving plate 354, the surface of the moving plate 354... The fixed support frame 352 can move synchronously, and the limiting ring 31 connected to the telescopic rod 33 inside the support frame 352 moves synchronously toward the center area of the limiting platform 1. When the limiting ring 31 comes into contact with the surface of the turbine shaft, it will be subjected to the reverse contact force of the turbine shaft. The turbine shaft squeezes the limiting ring 31, and the limiting ring 31 squeezes the telescopic rod 33 simultaneously. The telescopic rod 33 retracts, and the knocking rod 351 fixed to the surface of the limiting ring 31 slides in the support plate 34 under force and strikes the bell 353. The bell 353 makes a sound to remind the operator, so as to intuitively understand whether the turbine shaft is fixed tightly and avoid loosening during the processing.
[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
