[0021] Further, the outer box 5 is fixed on one side of the top end of the machine tool body 1, Y-axis guide rails 9 are arranged on both side end faces of the machine tool body 1 in the length direction of the machine tool body 1, the Y-axis guide rails 9 are arranged in a longitudinal direction on both sides of the outer box 5 close to the edges of the Y-axis movable slot 7, the main shaft box body 6 has a first connecting part 10 and a second connecting part 11 extending out of the Y-axis movable slot 7, the first connecting part 10 is arranged on one side close to the cutter tower mechanism 4, the second connecting part 11 is arranged on one side away from the cutter tower mechanism 4, guide blocks 12 connected with the corresponding Y-axis guide rails 9 are arranged on the first connecting part 10 and the second connecting part 11, guide grooves 13 are formed in the guide blocks 12, the Y-axis guide rails 9 extend into the guide grooves 13 and are connected with the guide blocks 12, and the main shaft box body 6 moves in the Y-axis direction in the Y-axis movable slot 7 along the Y-axis guide rails 9 under the drive of the Y-axis power mechanism 8. Specifically, in this embodiment, the first connecting part 10 is used to fix the workpiece, and the second connecting part 11 is used to mount an electric spindle brake 20 for braking an electric spindle 19, the movement of the main shaft box body 6 in the Y-axis direction is more stable and accurate by arranging the Y-axis guide rails 9 and the guide blocks 12. In addition, the cooperation between the Y-axis guide rails 9 and the guide blocks 12 ensures the stability and reliability of the main shaft box body 6 during high-speed movement. When the main shaft box body 6 moves under the drive of the Y-axis power mechanism 8, the guide blocks 12 slide along the Y-axis guide rails 9, and due to the close cooperation between the guide blocks 12 and the Y-axis guide rails 9, the friction and wear during movement can be effectively reduced, thereby prolonging the service life of the machine tool.

[0022] Furthermore, a brake 14 is provided on the outer housing 5. The brake 14 comprises an outer housing connection portion 15 and a braking portion 16. The outer housing connection portion 15 is fixedly connected to the outer housing 5. The braking portion 16 defines a braking groove 17. A braking end 18 is provided on the end of the spindle housing body 6 that extends out of the Y-axis movable groove 7. The braking end 18 extends into the braking groove 17 and connects to the brake 14. A gap is formed between the braking end 18 and the groove walls of the braking groove 17. Specifically, in this embodiment, a gap is formed between the braking end 18 and the groove walls of the braking groove 17 to ensure that excessive friction is not generated between the braking end 18 and the braking groove 17 during braking, thereby avoiding unnecessary damage to the spindle housing body 6. Furthermore, the braking portion 16 of the brake 14 is fixedly connected to the outer housing 5 via the outer housing connection portion 15, making the brake 14 more structurally stable and capable of effectively braking the electric spindle 19. During the braking process, the brake 14 decelerates and stops the electric spindle 19 through the contact between the braking end 18 and the braking groove 17, thereby ensuring the safety and reliability of the machine tool during the processing.

[0023] Furthermore, the brake 14 is made of plastic, and when the brake 14 is squeezed, at least one side of the groove wall of the brake 14 contacts the brake end 18. Specifically, in this embodiment, by squeezing the groove wall of the brake groove 17 into contact with the brake end 18, the guide rail can be braked instead of the traditional brake 14. The friction between the groove wall of the brake groove 17 and the brake end 18 helps overcome the force of the brake plate movement, thereby acting as a guide rail brake. This is low-cost and simple in structure, and can help stabilize workpiece processing.

[0024] Furthermore, an electric spindle 19 is rotatably disposed within the spindle housing body 6. An electric spindle brake 20 is disposed on the second connecting portion 11 and is connected to the electric spindle 19. Specifically, in this embodiment, the electric spindle 19 is a rotating shaft on the machine tool body 1. The electric spindle brake 20 has the same structure as the brake 14 described above. During machine tool operation, the high-speed rotation of the electric spindle 19 is key to achieving efficient machining. To ensure that the electric spindle 19 can be stopped quickly and accurately when needed, the design of the electric spindle brake 20 is crucial. In this embodiment, the electric spindle brake 20 is connected to the electric spindle 19 via the second connecting portion 11, ensuring a tight fit between the brake 14 and the electric spindle 19. When the brake 14 receives a stop signal, it actuates rapidly, generating sufficient friction through the contact between the brake end 18 and the brake groove 17 to rapidly decelerate and stop the electric spindle 19.

[0025] Further, the tool turret mechanism 4 includes a tool turret base plate 21 and a power tool holder 22 and a turning tool holder 23 arranged on the tool turret base plate 21. Specifically, in the present embodiment, the power tool holder 22 and the turning tool holder 23 are both prior art, and thus will not be described here, and the tool turret base plate 21 moves in the Z-axis direction on the tool turret mounting plate 3.

[0026] The Y-axis power mechanism 8 includes a motor 24 and a ball screw 25, and the motor 24 is connected to the ball screw 25 through a transmission belt. When the motor 24 is started, the transmission belt (not shown in the figure) drives the ball screw 25 to rotate, and the rotation is converted into linear motion, so as to realize the movement of the spindle box body 6 in the Y-axis movable groove 7.

[0027] The above description of disclosed embodiments enables those skilled in the art to make or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will accord with the widest scope consistent with the principles and novel features disclosed herein.
