[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0022] like Figures 1 to 4 As shown, an embodiment of the present utility model proposes a water outlet structure for the spindle center of a gantry machining center, including a mounting frame 1, a plurality of guide rails 2 are fixedly connected to the side of the mounting frame 1, a sliding frame 3 is slidably arranged on the guide rail 2, a main motor 4, a ZF reduction box 5 and a first reduction box 6 are fixedly installed in the mounting frame 1, a spindle body 7 is provided at one end of the output shaft of the first reduction box 6, the main motor 4, the ZF reduction box 5 and the first reduction box 6 are connected in sequence, the output shaft of the first reduction box 6 and the spindle body 7 are provided with circular through holes, the output shaft of the first reduction box 6 and the center of the circular through hole on the spindle body 7 are on the same axis, the main motor 4 is first connected to the ZF reduction box 5, and the ZF reduction box 5 is then connected to the first reduction box 6. A reduction box 6 is connected, and the ZF reduction box 5 is used to realize efficient power transmission of the main motor 4, reducing the input high-speed rotation power to the required output speed, while improving the output torque. At the same time, with the help of the high-precision characteristics of the ZF reduction box 5, the working accuracy is improved, and then the output of the ZF reduction box 5 is controlled and adjusted by the first reduction box 6 to reduce the speed to a speed suitable for the operation of the main shaft body 7. By reducing the speed, the torque of the main shaft body 7 is increased. The speed reduction ratio of the main shaft body 7 can reach 1:64 and 1:1.6, which can meet the needs of high-speed rotation and low-speed high-torque cutting, and is flexible and convenient to use. At the same time, by setting a circular through hole, the mounting frame 1 structure can realize the water outlet function of the main shaft center, which is convenient for maintenance.

[0023] like Figure 3 and Figure 4 As shown, the main shaft of the main motor 4 is installed together with the ZF reducer 5, and the ZF reducer 5 is connected to the first reducer 6. The upper end of the output shaft on the first reducer 6 is rotatably provided with a rotary joint 8, and the rotary joint 8 is fixedly connected to the mounting frame 1. The main shaft body 7 is installed inside the mounting frame 1, and the main shaft body 7 extends from the lower end of the mounting frame 1 to the inside of the mounting frame 1. A through hole is provided inside the rotary joint 8, and the through hole is opposite to the circular through hole in the output shaft of the first reducer 6. The rotary joint 8 is used to connect the infusion tube to transport different liquids, such as cutting fluid or water.

[0024] like Figure 2 and Figure 3 As shown, a coupling 9 is provided inside the mounting frame 1, and a circular channel is provided inside the coupling 9. One end of the coupling 9 is fixed to the output shaft of the first reduction gearbox 6, and the other end is fixed to the main shaft body 7.

By using couplings 9 of different lengths, the flexibility of device installation is greatly improved.

[0025] like Figure 1 As shown, the shape of the sliding frame 3 is C-shaped, and a slide 11 is fixedly installed at a position close to the sliding frame 3 and the mounting frame 1. The slide 11 is slidably connected to the guide rail 2. Two balancing cylinders 12 are fixedly connected to the sliding frame 3. The balancing cylinders 12 are located on both sides of the mounting frame 1. The two balancing cylinders 12 and the mounting frame 1 are symmetrically arranged. A mounting seat 13 is fixedly connected to the mounting frame 1, and the telescopic rod of the balancing cylinder 12 is hinged to the mounting seat 13.

The balancing cylinders 12 on both sides provide a driving force to cause relative sliding between the sliding frame 3 and the mounting frame 1.

[0026] Working principle: The main motor 4 is first connected to the ZF reducer 5, and efficient power transmission of the main motor 4 is achieved through the ZF reducer 5. The output of the ZF reducer 5 is then controlled and adjusted by the first reducer 6. By setting a circular through hole, the mounting frame 1 structure can realize the water outlet function of the main shaft center. The balancing oil cylinders 12 on both sides provide driving force, so that relative sliding occurs between the sliding frame 3 and the mounting frame 1.
