[0030] like Figures 1 to 5 As shown, a tool magazine high-precision transmission mechanism comprises: a support bracket 1, a drive motor 2 and a transmission chain 3;

[0031] The driving motor 2 is fixedly arranged on the inner side of the supporting bracket 1;

[0032] A driving wheel 31 and a driven wheel 32 are provided at the two ends corresponding to the inner ring side of the transmission chain 3;

[0033] The output shaft 21 of the driving motor 2 is meshed with the central portion 31A of the driving wheel 31 , the driving wheel 31 is meshed with the transmission chain 3 , and the driven wheel 32 is meshed with the transmission chain 3 .

[0034] The driving motor 2 is started first, and its output shaft 21 starts to rotate. The rotational power is transmitted to the driving wheel 31 through the transmission mechanism. The driving wheel 31 is tightly meshed with the inner ring side of the transmission chain 3. When the driving wheel 31 is driven by the driving motor 2 to start rotating, it drives the transmission chain 3 to start circulating movement through the meshing action. The transmission chain 3 is a closed ring structure, and its inner ring side is meshed not only with the driving wheel 31 but also with the driven wheel 32. When the transmission chain 3 is driven to move by the driving wheel 31, the driven wheel 32 also rotates, further realizing the movement of the tool in the tool magazine.

[0035] The continuous cyclic movement of the transmission chain 3 ensures the continuity and stability of power transmission, making the tool replacement process faster and more accurate, improving the processing efficiency, and the precise engagement of the transmission chain 3 also ensures the improvement of transmission accuracy and reduces processing errors; the tool magazine transmission mechanism realizes automatic replacement and storage of tools through the coordinated work of the drive motor 2, the active wheel 31, the transmission chain 3 and the driven wheel 32, greatly reducing the need for manual intervention, reducing the difficulty of operation and labor intensity, and also improving the consistency and reliability of processing; the design of the support bracket 1 ensures the stability and reliability of the tool magazine transmission mechanism under long-term, high-load operation, helps to extend the service life of the tool magazine transmission mechanism, reduce failures and maintenance costs, and improve the overall performance and economic benefits of CNC machine tools.

[0036] As a preferred embodiment of the above, a base 4 is provided below the support bracket 1, a slide rail 41 is fixedly provided on the base 4, and a slider 11 is fixedly provided on one side of the bottom of the support bracket 1;

[0037] The slide rail 41 is cooperatively arranged with the slider 11 to realize the movement of the support bracket 1 in the horizontal direction.

[0038] When the position of the tool magazine transmission mechanism needs to be adjusted, the support bracket 1 is operated to slide on the slide rail 41, and the drive motor 2, the driving wheel 31 and the transmission chain 3 meshed with the driving wheel 31 fixed on the inner side of the support bracket 1 will also move in the horizontal direction accordingly.

[0039] A base 4 and a slide rail 41 are arranged below the support bracket 1, and a slider 11 is arranged at the bottom of the support bracket 1, so as to realize the horizontal movement of the support bracket 1, increase the flexibility of the tool magazine transmission mechanism, and enable it to be quickly adjusted according to different processing requirements or machine tool layouts; the coordinated design of the slide rail 41 and the slider 11 ensures the smoothness and continuity of the movement of the support bracket 1, improves the working accuracy and stability of the tool magazine transmission mechanism, helps to reduce processing errors caused by improper position adjustment, and improves the overall performance of the CNC machine tool.

[0040] In this embodiment, a drag chain 12 is fixedly provided on the other side of the support bracket 1 away from the sliding block 11 .

[0041] The drag chain 12 is mainly used to protect and manage the wires, hoses, etc. of the equipment on the support bracket 1. When the tool magazine transmission mechanism is working, the support bracket 1 may move on the slide rail 41 as needed, and as the support bracket 1 moves, the drag chain 12 fixed thereon will also move accordingly.

[0042] By fixing the drag chain 12 on the other side of the support bracket 1 away from the slider 11, the wires, hoses and other equipment can be effectively protected and managed. The drag chain 12 keeps the lines neat and orderly when the support bracket 1 moves, avoiding damage and failure caused by pulling, crushing or kinking; the guiding and protection functions of the drag chain 12 also improve the safety of mechanical equipment, reduce the possibility of foreign matter entering the interior of the mechanical equipment, reduce damage and failure of the lines, and also extend the service life of the mechanical equipment, reducing the cost of maintenance and replacement.

[0043] In this embodiment, a translation cylinder 5 is provided between the support bracket 1 and the base 4 , one end of the translation cylinder 5 is fixedly connected to the bottom of the support bracket 1 , and the other end of the translation cylinder 5 is fixedly connected to the base 4 .

[0044] When the position of the support bracket 1 needs to be adjusted, the translation cylinder 5 will receive the control signal and start working. According to the signal requirements, the translation cylinder 5 will extend or shorten. When the cylinder is extended, it will push the support bracket 1 to move in a certain direction on the slide rail 41; when the cylinder is shortened, it will pull the support bracket 1 to move in the opposite direction.

[0045] By arranging a translation cylinder 5 between the supporting bracket 1 and the base 4, accurate and rapid movement of the supporting bracket 1 is achieved. The stability and precise control of the translation cylinder 5 ensure the accuracy and reliability of the position of the supporting bracket 1, and improve the performance of the entire tool magazine transmission mechanism. The translation cylinder 5 has a fast response speed, which makes the position adjustment process more efficient, reduces the adjustment time, and improves work efficiency. The use of the translation cylinder 5 also simplifies the operation process of position adjustment, reduces the difficulty of operation, and improves the convenience of operation.

[0046] As a preferred embodiment of the above embodiment, a photoelectric switch 13 is provided on the top of the supporting bracket 1 .

[0047] A photoelectric switch 13 is set on the top of the support bracket 1, which is specifically used to detect the position or state of the tool. The photoelectric switch 13 will continuously emit light beams and monitor whether these light beams are blocked. When the tool moves into the sensing range of the photoelectric switch 13, it will block the light beam emitted by the photoelectric switch 13. This change will be quickly captured by the receiver of the photoelectric switch 13 and trigger the corresponding signal output. This signal will then be received by the control system or the main control system of the machine tool. The control system can quickly determine the current position or state of the tool based on the received signal. If the position or state of the tool is inconsistent with expectations, the control system can respond immediately, such as pausing processing, issuing an alarm, or adjusting the position of the tool.

[0048] A photoelectric switch 13 is arranged on the top of the supporting bracket 1, which can realize real-time and accurate monitoring of the tool position, enhance the automation and intelligence level of the CNC machine tool, reduce the need for manual intervention, and improve the stability and reliability of the processing process; through the monitoring of the photoelectric switch 13, the machine tool can promptly detect the deviation or abnormal state of the tool position, avoid potential safety hazards and processing errors, help protect the machine tool and the tool itself, extend its service life, and reduce maintenance costs; the photoelectric switch 13 has the characteristics of fast response, high sensitivity and long-term stable operation, and can adapt to high-intensity and high-precision processing requirements. It works in coordination with other control systems or machine tool components to jointly ensure the efficient and accurate processing of CNC machine tools.

[0049] In this embodiment, a reducer 22 is fixedly disposed on one side of the driving motor 2 .

[0050] The main function of the reducer 22 is to convert the high-speed, low-torque power output by the drive motor 2 into low-speed, high-torque power. When the drive motor 2 starts working, it will output power at a certain speed, which is transmitted to the reducer 22 through the connection between the drive motor 2 and the reducer 22. A series of gears, bearings 33 and other components inside the reducer 22 will interact with each other, gradually reducing the speed and increasing the torque. After the conversion by the reducer 22, the original high-speed, low-torque power is converted into low-speed, high-torque power.

[0051] A reducer 22 is fixedly arranged on one side of the drive motor 2, which realizes the effective conversion of the output power of the drive motor 2, makes the power more suitable for the working requirements of the tool magazine transmission mechanism, and improves the operating efficiency and stability of the entire system; the use of the reducer 22 also reduces the power required for the drive motor 2 to directly drive high-load components, thereby reducing energy consumption and operating costs; the reducer 22 also plays a role in protecting the drive motor 2 and the transmission mechanism, extending their service life.

[0052] In this embodiment, both the driving wheel 31 and the driven wheel 32 are provided with bearings 33 for support.

[0053] Both the driving wheel 31 and the driven wheel 32 are provided with bearings 33, which are mainly used to support the rotating body and reduce the friction and wear between the rotating body and the fixed body. When the driving wheel 31 starts to rotate, its bearing 33 starts to play a role, and the balls or rollers inside the bearing 33 enable the driving wheel 31 to rotate smoothly on the shaft, reducing the resistance caused by friction, so that the driving wheel 31 can transmit power more efficiently. Similarly, the driven wheel 32 also starts to rotate when receiving the power transmitted by the driving wheel 31, and its bearing 33 also plays a role in supporting and reducing friction.

[0054] The driving wheel 31 and the driven wheel 32 are supported by bearings 33, which can significantly reduce the friction between the wheels and the shaft and improve the efficiency of the mechanical transmission. The use of the bearings 33 also increases the rotational stability of the wheels and reduces the failure rate caused by friction and wear. The design of the bearings 33 also makes the maintenance and replacement of the driving wheel 31 and the driven wheel 32 more convenient, thereby improving the maintenance efficiency of the mechanical equipment.

[0055] In this embodiment, the transmission chain 3 is made of high-strength and wear-resistant material.

[0056] Due to the use of high-strength materials, the transmission chain 3 can withstand greater tension and pressure and is not prone to breakage or deformation. At the same time, the wear-resistant material properties enable the transmission chain 3 to resist wear and friction during long-term operation and maintain a good meshing state between the chain links and gears. During operation, the transmission chain 3 exhibits excellent stability and reliability. It can withstand high loads and long-term operation, reducing failures and downtime caused by breakage or deformation of the transmission chain 3. The wear-resistant material properties also extend the service life of the transmission chain 3, reduce the frequency of maintenance and replacement, and reduce the cost of use. The application of high-strength materials also improves the overall strength and rigidity of the transmission chain 3, reduces the vibration and noise of the transmission chain 3 during operation, and improves the working environment and operating experience of the machine tool.
