Description
Technical Field
[0001] This utility model relates to the field of flywheel machining and clamping technology, and in particular to a flywheel machining and clamping mechanism for a vertical lathe. Background Technology
[0002] The flywheel machining clamping mechanism on a vertical lathe is mainly used for machining flywheels on a vertical lathe, ensuring stable clamping of the flywheel during machining while achieving efficient and precise processing. The function of the vertical lathe flywheel machining clamping mechanism is to fix the flywheel onto the spindle of the vertical lathe for various turning operations. Flywheels are typically circular, with a large outer diameter and a small inner diameter, and are usually made of hard material with an irregular shape. This mechanism, through a reasonable clamping method, keeps the flywheel stable during machining, preventing vibration, loosening, or deformation during high-speed rotation.
[0003] Vertical lathes, as important machining equipment, are widely used in machining large workpieces, especially in the machining of heavy rotating workpieces such as flywheels and gears, where they have irreplaceable advantages. However, due to the large size, complex shape, and hard material of flywheels, high requirements are placed on clamping accuracy, stability, and safety during machining. Existing flywheel machining clamping devices mostly use simple mechanical fixtures for fixing, which often cannot guarantee the accuracy and stability of the clamping process when dealing with flywheels of different sizes, shapes, and materials, resulting in low machining accuracy, or even workpiece deformation or poor machining. Therefore, a vertical lathe flywheel machining clamping mechanism is proposed to solve the above problems. Utility Model Content

[0007] A conical fixed block is fixedly connected to the center of the turntable. Movable blocks are slidably connected at intervals inside the fixed block. An elastic component is fixedly connected to the bottom of the movable block.

[0008] As a further description of the above technical solution:
[0009] The positioning component includes a spring, one end of which is fixedly connected to the inner wall of the housing, and the other end of which is fixedly connected to a positioning head.
[0010] As a further description of the above technical solution:
[0011] The adjusting rod has evenly distributed positioning holes on the side away from the center, and the positioning head is slidably connected inside the positioning holes.
[0012] As a further description of the above technical solution:
[0013] The elastic component includes a connecting block, which is fixedly connected to the bottom of the movable block. A telescopic rod is fixedly connected to one side of the connecting block, and a spring is sleeved on the outside of the telescopic rod.
[0014] As a further description of the above technical solution:
[0015] The turntable has evenly distributed grooves at its center. One end of the telescopic rod is fixedly connected to the inner wall of the groove, and the connecting block is slidably connected inside the groove.
[0016] As a further description of the above technical solution:
[0017] One end of the second spring is fixedly connected to the inner wall of the slide groove, and the other end of the second spring is fixedly connected to one side of the connecting block.

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, by pulling the pressure block, the upper half of the adjusting rod slides inside the lower side of the adjusting rod, while simultaneously squeezing the positioning head, moving it out of the positioning hole and into the outer shell. This squeezes the first spring, generating a rebound force. When the height of the pressure block is adjusted to match the height of the flywheel, the positioning head is no longer squeezed and is reinserted into the positioning hole under the rebound force of the first spring. Then, the motor is started, driving the turntable to rotate, causing the adjusting rod to slide in the arc groove, clamping and fixing the flywheel. At the same time, the pressure block tightly presses against the flywheel, achieving precise clamping and fixing, ensuring stability during operation, and is applicable to flywheels of different sizes, improving the practicality of the device.
[0022] 2. In this utility model, by fitting the flywheel onto the outside of the fixed block, pressure is applied to the movable block, causing it to move and drive the connecting block to slide into the groove. At the same time, the telescopic rod and the second spring are squeezed, generating a rebound force. When the flywheel is in contact with the turntable, the rebound force of the telescopic rod and the second spring pulls the movable block, making it fit tightly against the inner wall of the flywheel, thus achieving positioning. This improves the stability and accuracy of the flywheel and ensures operational safety. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of a vertical lathe flywheel machining clamping mechanism, including a mounting frame 4. A motor 5 is installed inside the mounting frame 4. A turntable 6 is fixedly connected to the output end of the motor 5. The turntable 6 is placed on the upper part of the mounting frame 4. Arc grooves 7 are opened at the four corners of the upper side inside the turntable 6. An adjusting rod 8 is slidably connected inside the arc grooves 7. A pressure block 9 is fixedly connected to the top of the adjusting rod 8 on the side close to it. A housing 10 is fixedly connected to the outer wall of the adjusting rod 8 on the side away from it. A positioning component is fixedly connected inside the housing 10. The positioning component is used to position the adjusted position of the adjusting rod 8. The positioning component includes a spring 11. One end of the spring 11 is fixedly connected to the inner wall of the housing 10. The other end of the spring 11 is fixedly connected to a positioning head 12. A uniformly distributed positioning hole 13 is opened inside the side of the adjusting rod 8 away from it. The positioning head 12 is slidably connected inside the positioning hole 13.
[0032] The bottom of the mounting bracket 4 is fixedly connected to the base plate 2, and the bottom of the base plate 2 is fixedly connected to the evenly distributed mounting blocks 3. The workbench 1 is mounted on the outside of the mounting blocks 3, and the base plate 2 is attached to the upper part of the workbench 1.
[0033] By pulling the pressure block 9, the upper half of the adjusting rod 8 slides inside the lower side of the adjusting rod 8, while simultaneously squeezing the positioning head 12 out of the positioning hole 13 and into the outer shell 10 to squeeze the spring 11, causing it to generate a rebound force. When the height of the pressure block 9 is adjusted to match the height of the flywheel, the positioning head 12 is no longer squeezed and is pushed back into the positioning hole 13 by the rebound force of the spring 11. Then, the motor 5 is started, causing the turntable 6 to rotate, so that the adjusting rod 8 slides inside the arc groove 7, clamping and fixing the flywheel. The pressure block 9 presses the flywheel tightly against it, achieving precise clamping and fixing of the flywheel, thus providing a stable foundation for subsequent processing or operation. Moreover, the shell is suitable for flywheels of different sizes, improving the practicality of the device.
[0034] Reference Figure 1 , Figure 2 , Figure 3A conical fixed block 14 is fixedly connected to the center of the turntable 6. A movable block 15 is slidably connected to the interior of the fixed block 14. An elastic component is fixedly connected to the bottom of the movable block 15. The elastic component is used to fit the movable block 15 against the inner wall of the flywheel and firmly position it on the turntable 6. The elastic component includes a connecting block 16, which is fixedly connected to the bottom of the movable block 15. A telescopic rod 17 is fixedly connected to one side of the connecting block 16. A second spring 18 is sleeved on the outside of the telescopic rod 17. A uniformly distributed sliding groove 19 is opened inside the center of the turntable 6. One end of the telescopic rod 17 is fixedly connected to the inner wall of the sliding groove 19. The connecting block 16 is slidably connected inside the sliding groove 19. One end of the second spring 18 is fixedly connected to the inner wall of the sliding groove 19, and the other end of the second spring 18 is fixedly connected to one side of the connecting block 16.
[0035] By fitting the flywheel onto the outside of the fixed block 14, it presses against the movable block 15. As the movable block 15 moves, it drives the connecting block 16, causing it to slide inside the slide groove 19. Simultaneously, it presses against the telescopic rod 17 and the second spring 18, generating a rebound force. When the flywheel is in contact with the turntable 6, the rebound force of the telescopic rod 17 and the second spring 18 pulls the movable block 15, causing it to press tightly against the inner wall of the flywheel for positioning. This achieves reliable positioning of the flywheel, improving its stability and accuracy, and ensuring safety during operation.
[0036] Working principle: When the device is needed, by clamping the flywheel onto the outside of the fixed block 14, pressure is applied to the movable block 15, causing it to move and drive the connecting block 16 to slide into the groove 19. At the same time, the telescopic rod 17 and the second spring 18 are compressed, generating a rebound force. When the flywheel is in contact with the turntable 6, the rebound force of the telescopic rod 17 and the second spring 18 pulls the movable block 15, making it tightly adhere to the inner wall of the flywheel, thus achieving positioning, improving the stability and accuracy of the flywheel, and ensuring operational safety. By pulling the pressure block 9, the upper half of the adjusting rod 8 is pushed to slide inside the lower side of the adjusting rod 8. Simultaneously, the positioning head 12 is pressed, moving out of the positioning hole 13 and into the outer shell 10. The spring 11 is pressed to generate a rebound force. When the height of the pressure block 9 is adjusted to match the height of the flywheel, the positioning head 12 is no longer pressed and is reinserted into the positioning hole 13 under the rebound force of the spring 11. Then, the motor 5 is started, driving the turntable 6 to rotate, causing the adjusting rod 8 to slide in the arc groove 7 to clamp and fix the flywheel. At the same time, the pressure block 9 tightly presses the flywheel to achieve precise clamping and fixation, ensuring stability during operation. It is also suitable for flywheels of different sizes, improving the practicality of the device.
