[0005] A slide block is provided at the lower end of the T-shaped slide block, and the slide block is mounted on the crossbeam of the machine tool. The T-shaped slide block and the slide block are slidably connected. A vertical ball screw is installed inside the slide block. The reducer is connected to the upper end of the ball screw through a coupling. The ball screw is fixedly connected to the inside of the T-shaped slide block through a screw bracket.
[0006] There are two balancing cylinders, which are respectively located on the left and right sides of the T-shaped slide block and the slide seat.
[0007] Furthermore, a balance cylinder is fixed at both ends of the slide block, with the piston end of the balance cylinder facing upwards; a cylinder bracket is fixed on both sides of the upper end of the T-shaped slide block, and the piston ends of the two balance cylinders are respectively fixed on their corresponding cylinder brackets.
[0008] Furthermore, a cable support bracket is fixedly connected to the T-shaped slide and the slide base. A cable is provided between the cable support bracket and the slide base.

[0017] like Figure 1 As shown in Figure 4, a vertical tool post with a double-cylinder and double-walled T-shaped slide includes a balance cylinder 1, a T-shaped slide 3, a slide block 6, a ball screw 7, a servo motor 8, a reducer 9, and a reducer bracket 10. The T-shaped slide 3 is arranged vertically, and a reducer bracket 10 is installed on the top of the T-shaped slide 3. A reducer 9 is installed on the reducer bracket 10. The servo motor 8 is installed above the reducer 9, and the drive end of the servo motor 8 is connected to the reducer 9.
[0018] A slide block 6 is provided at the lower end of the T-shaped slide block 3. The slide block 6 is installed on the crossbeam of the machine tool, and the T-shaped slide block 3 is slidably connected to the slide block 6. A vertical ball screw 7 is installed inside the slide block 3. The reducer 9 is connected to the upper end of the ball screw 7 through the coupling 11. The ball screw 7 is fixedly connected to the inside of the T-shaped slide block 3 through the screw bracket.
[0019] A balance cylinder 1 is fixed at both ends of the slide block 6, with the piston end of the balance cylinder 1 facing upwards; a cylinder bracket 4 is fixed on both sides of the upper end of the T-shaped slide block 3, and the piston ends of the two balance cylinders 1 are respectively fixed on their corresponding cylinder brackets 4.
[0020] A cable support 5 is fixedly connected to the T-shaped slide block 3 and the slide seat 6. A cable 2 is provided between the cable support 5 and the slide seat 6. One end of the cable 2 is connected to the cable support 5, and the other end of the cable 2 is connected to the slide seat 6.
[0021] During operation, the output of the servo motor 8 drives the ball screw 7 to rotate via the reducer 9 and coupling 11. The reducer 9 converts the high-speed rotation of the servo motor 8 into low-speed, high-torque rotation of the output shaft, precisely controlling the speed. During rotation, the ball screw 7 drives the nut to move the T-shaped slide 3 vertically up and down. The T-shaped slide 3 moves on the slide block 6, which in turn moves the hydraulic cylinder bracket 4. The hydraulic cylinder bracket 4 causes the piston end of the balance cylinder 1 to extend and retract. When the T-shaped slide 3 moves upward, the piston end of the balance cylinder 1 extends; when the T-shaped slide 3 moves downward, the piston end of the balance cylinder 1 retracts into the cylinder body. In this way, the servo motor 8, reducer 9, and reducer bracket 10 move together. The T-shaped slide 3 moves together; the ball screw nut mechanism converts the rotational motion into linear motion, thereby driving the T-shaped slide 3 to move vertically until it is adjusted to the appropriate machining position; the T-shaped slide 3 is made of QT600-3 cast ductile iron material with surface hardening; the T-shaped slide 3 is equipped with a double hydraulic cylinder balancing device, and the balancing cylinders 1 on both sides can balance part of the vertical weight of the T-shaped slide 3, so that the driving force of the T-shaped slide 3 moving up and down is uniform, the T-shaped slide 3 moves more smoothly, and effectively provides linear accuracy; the slide 6 can move horizontally on the crossbeam, and the T-shaped slide 3 moves vertically, both driven by an AC servo motor device, which drives the ball screw 7 to rotate through the reduction device to achieve rapid feed of the tool post.
