[0002] The CNC turntable is an important part of the CNC machine tool, and its function is to realize the indexing and rotary motion of the machine tool. During the operation of the CNC turntable, it needs to be braked to ensure the processing accuracy and safety. When a major fault occurs in the device, a gear brake mechanism is needed to stop the turntable from rotating to ensure the safety of the on-site working environment.

[0003] Some common brake mechanisms have poor braking effects. When the turntable needs to be stopped immediately, there is often a delay, which makes it easy to cause deviations or errors in the processing process. In addition, existing technologies often face challenges in terms of braking stability. When only relying on a single gear locking method to stop the rotation, instability is prone to occur, such as poor braking effect due to uneven force problems, and may even cause failures.

[0004] Therefore, it is necessary to provide a gear brake mechanism for a numerically controlled turntable to solve the above technical problems. Utility Model Content

The CNC turntable adopts a scroll 6 and a worm rod 5 to drive the turntable 8 to move, which can not only achieve smoother and more efficient power transmission, but also can utilize the gear on the worm rod 5 to make the turntable 8 react quickly to stop rotating, which greatly improves the response speed and safety of the equipment.

[0021] The pressing plate 11 is provided with a pressing button 15, and the front of the workbench 1 is provided with a cylinder 16, and a telescopic column 17 is slidably connected to the cylinder 16, and a second brake gear sleeve 18 is fixedly connected to the telescopic column 17, and the second brake gear sleeve 18 is adapted to the large gear 4. When the manual brake is applied, the pressing button 15 can be pressed to start the cylinder 16 through electrical connection, and the cylinder 16 extends the second brake gear sleeve 18 to engage the large gear 4, and at the same time, the two gears are deformed and pressed to stop rotating, thereby enhancing the reliability and stability of the brake mechanism. The two gears act at the same time, which disperses the force, reduces the load of a single gear, effectively reduces the probability of failure, and prolongs the service life of the equipment.

[0022] Four processing support columns 19 are fixedly connected to the top of the workbench 1 , and a processing support plate 20 is fixedly connected to the top of the processing support columns 19 . A processing mechanism 21 is installed on the processing support plate 20 , and the processing mechanism 21 processes the workpiece on the turntable 8 .

[0023] A maintenance door 22 is provided on the left side of the workbench 1 , and four supporting legs 23 are fixedly connected to the bottom of the workbench 1 . The CNC turntable and the brake mechanism can be maintained through the maintenance door 22 .

[0024] A numerical control board 24 is installed on the front of the workbench 1. An interactive screen 25 is arranged on the numerical control board 24.

[0025] The numerical control board 24 is electrically connected to the motor 2, the numerical control board 24 is electrically connected to the push button 15, and the numerical control board 24 is electrically connected to the cylinder 16. A numerical control system is arranged inside the numerical control board 24 to control the start and stop of the motor 2 to control the rotation direction of the turntable 8. At the same time, when the push button 15 is pressed, a signal can be transmitted to the cylinder 16 to start the cylinder 16.

[0026] The working principle of the gear brake mechanism of a CNC turntable provided by the utility model is as follows:

[0027] When the device is working, the motor 2 starts, and the large gear 4 rotates by engaging the small gear 3, and then the worm rod 5 starts to rotate and drives the scroll 6 to rotate, and then the turntable 8 starts to rotate. A clamp can be installed on the turntable 8 to clamp the workpiece for processing. When the device needs to be stopped quickly, the rotation of the motor 2 is stopped immediately. At this time, due to inertia, the worm rod 5 may still rotate. At this time, the operator can press the pressing plate 11 to make the first brake gear sleeve 12 quickly clamp on the manual brake gear 14, so that the worm rod 5 stops rotating quickly. Since the scroll 6 cannot drive the worm rod 5 to rotate, the scroll 6 stops rotating after the worm rod 5 stops rotating. Only a small amount of effort is needed to make the overall braking response of the device quick. After stopping, the sliding rod 10 can be automatically reset by the spring 13. The brake mechanism can avoid accidents and ensure the safety of operators and the continuity of the production process.

[0028] Compared with the related art, the toothed brake mechanism of a CNC turntable provided by the utility model has the following beneficial effects:

[0029] The CNC turntable uses the scroll 6 and the worm 5 to drive the turntable 8 to move, which can not only achieve a smoother and more efficient power transmission, but also can use the characteristic that the turntable 8 can quickly respond and stop rotating by blocking the gear on the worm 5, which greatly improves the response speed and safety of the equipment. In an emergency, it can brake quickly to avoid accidents, ensure the safety of operators and the continuity of the production process. At the same time, the innovative design of setting two gears on the worm 5 enhances the reliability and stability of the brake mechanism. The two gears act at the same time, disperse the force, reduce the load of a single gear, effectively reduce the probability of failure, and extend the service life of the equipment.
