[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] The utility model provides the following technical solutions:

[0019] As attached Figures 1-3As shown, the utility model discloses a spindle box for use in a turning-milling compound machine tool, comprising an outer box body 1 and a spindle box 2, wherein a Y-axis movable groove 3 is provided in the outer box body 1, and the spindle box 2 is arranged in the Y-axis movable groove 3. A power mechanism 4 is provided at the top end of the outer box body 1, and one end of the power mechanism 4 extends into the Y-axis movable groove 3 and is connected to the spindle box 2. A guide member 5 is provided on a portion of the end face of one side of the outer box body 1 close to the Y-axis movable groove 3, and the spindle box 2 has a guide connection portion 6 extending out of the Y-axis movable groove 3, and the guide connection portion 6 is connected to the guide member 5. The power mechanism 4 drives the spindle box 2 to reciprocate along the guide member 5 in the Y-axis movable groove 3. Specifically, in this design, by providing the guide member 5 on a portion of the end face of one side of the outer box body 1 close to the Y-axis movable groove 3, the guide member 5 is provided in a longitudinal structure and serves as the Y-axis of the lathe. During turning, the spindle box 2 is locked by the spindle box brake 8, so that the spindle box 2 maintains good rigidity. Compared with the traditional turret Y-axis and interpolation Y-axis, this structure is easy to maintain, easy to assemble, and has good rigidity.

[0020] Furthermore, the guide member 5 is a guide rail longitudinally arranged on the end face of one side of the outer box body 1 near the edges of both sides of the Y-axis movable groove 3, and guide blocks 7 are arranged on both sides of the end of the spindle box 2 extending out of the Y-axis movable groove 3. The guide connecting portion 6 is a guide groove structure opened on the side of the guide block 7 close to the outer box body 1, and one end of the guide member 5 extends into the guide connecting portion 6 and is connected to the guide block 7. Specifically, in this embodiment, a sliding fit is adopted between the guide block 7 and the guide groove to ensure the smoothness and positioning accuracy of the spindle box 2 when it moves in the Y-axis movable groove 3. The material of the guide block 7 is selected from alloy steel with good wear resistance to withstand friction and wear during long-term work. At the same time, a lubricating oil channel is provided in the guide groove, which further extends the service life of the guide system and reduces maintenance costs through regular and quantitative lubrication.

[0021] Furthermore, a spindle box brake 8 is provided on the outer box body 1. The spindle box brake 8 has an outer box connecting end 9 and a spindle box connecting end 10. The outer box connecting end 9 is fixed to the end faces of the outer box body 1 on both sides. The spindle box connecting end 10 has a brake groove 11. One end of the spindle box 2 extending out of the Y-axis movable groove 3 extends out of the brake groove 11 and is connected to the spindle box brake 8. Specifically, in this embodiment, the spindle box brake 8 is fixedly connected to the spindle box connecting end 10 by bolts, ensuring that the brake can quickly and reliably lock the spindle box 2 in an emergency and prevent it from accidentally moving during high-speed rotation. In addition, the brake is made of high-strength alloy steel to withstand the huge pressure and impact generated during braking.

[0022] Furthermore, brake connectors 12 are provided on both sides of one end of the spindle box 2 extending out of the Y-axis movable slot 3. The brake connector 12 has a brake end 13, which extends into the brake slot 11 and connects to the spindle box brake 8. A gap exists between the groove walls on both sides of the brake slot 11 and the brake end 13, pressing the spindle box brake 8. The groove walls on both sides of the brake slot 11 press the brake end 13. Specifically, in this embodiment, the brake connector 12 is fixedly connected to the spindle box 2, and the brake end 13 of the brake connector 12 extends into the brake slot 11. When braking is required, one side of the spindle box brake 8 is pressed, so that the groove wall on one side of the brake slot 11 contacts the brake end 13, thereby increasing friction and achieving rapid braking of the spindle box 2. To ensure the stability and reliability of the braking effect, the material of the brake connector 12 is also selected from high-strength alloy steel. In addition, the connection between the brake connector 12 and the spindle box 2 is fixed by bolts to ensure that during emergency braking, the brake connector 12 can be firmly fixed to the spindle box 2 to avoid loosening due to vibration or impact.

[0023] Furthermore, the power mechanism 4 includes a ball screw 14 and a motor 15, and the two ends of the ball screw 14 are respectively connected to the motor 15 and the spindle box 2. Specifically, in this embodiment, the ball screw 14 is connected to the output shaft of the motor 15 and the transmission components in the spindle box 2 through the threads at its two ends. The motor 15 converts the rotational motion into linear motion by driving the ball screw 14 to rotate, thereby driving the spindle box 2 to move precisely along the Y-axis. In order to improve transmission efficiency and accuracy, the connection between the ball screw 14, the motor 15 and the spindle box 2 is supported by precision bearings to ensure that there is no additional friction and clearance during movement.

[0024] Furthermore, a rear guide 16 is provided on the end surface of the outer box 1 away from the guide 5, and the rear guide 16 is provided corresponding to the guide 5. Specifically, in this embodiment, the rear end of the spindle box 2 is guided by the rear guide 16, thereby improving the stability of the spindle box 2 during movement.

[0025] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
