[0002] A servo tailstock is a commonly used auxiliary device on a machine tool, mainly used to support a workpiece and convert rotational motion into linear motion. It realizes precise positioning and control of the workpiece through components such as a servo motor, an encoder, and a control system, ensuring high precision and stability during the machining process.

[0003] The conical chuck of the existing servo tailstock is always collinear with the central axis of the cylindrical workpiece to be turned. However, when turning the cylinder into a cone, the position of the servo tailstock needs to be adjusted. At this time, in order to ensure the stable clamping of the object by the conical chuck, its angle also needs to be adjusted to be collinear with the central axis of the cone. Therefore, a servo tailstock for a numerically controlled lathe is required. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a servo tailstock for a numerically controlled lathe.

[0005] According to the first aspect embodiment of the utility model, a servo tailstock for a numerically controlled lathe is provided, including a base. A guide groove is formed on the upper surface of the base, and a slider is slidably connected to the inner wall of the guide groove. A support seat is fixedly connected to the upper surface of the slider, and an adjustment and positioning mechanism is fixedly connected to the inner wall of the support seat; the adjustment and positioning mechanism includes a threaded sleeve fixedly connected to the inner wall of the support seat. A first screw rod is threadedly connected to the inner wall of the threaded sleeve. One end of the first screw rod is rotatably connected to a connection block, and an arc-shaped plate is fixedly connected to one end of the connection block.

A conical head is fixedly connected to one end of the moving plate.

[0006] According to the servo tailstock for a numerically controlled lathe described in the first aspect embodiment of the utility model, a plurality of positioning grooves are formed on the surface of the arc-shaped plate, and a positioning pin is slidably connected to the inner wall of the moving plate. The positioning pin is adapted to the inner wall of the positioning groove.

[0007] According to the servo tailstock for a numerically controlled lathe described in the first aspect embodiment of the utility model, an L-shaped plate is fixedly connected to the surface of the support seat, and the lower surface of the connection block is slidably connected to the upper surface of the L-shaped plate.

[0008] According to the servo tailstock for a numerically controlled lathe described in the first aspect embodiment of the utility model, a hand crank wheel is fixedly connected to the end of the first screw rod away from the arc-shaped plate.

[0009] According to the servo tailstock for a numerically controlled lathe described in the first aspect embodiment of the present utility model, a chute is provided on the lower surface of the base, a scale line is fixedly connected to the upper surface of the base, and a mark is fixedly connected to the surface of the support base.

One end of the moving plate 17 is fixedly connected to a tapered head 11.

[0026] With the above structure, by setting the support seat 3, the installation and support of the threaded sleeve 10 and the ball head 4 are realized. By setting the first lead screw 8, the position of the arc-shaped plate 9 is adjusted. By setting the rotating shaft 15, the rotation stability of the ball head 4 is maintained. By setting the through hole 16, spatial avoidance is provided for the sliding of the moving plate 17. By setting the avoidance groove 14, spatial avoidance is provided for the movement of the tapered head 11. By setting the tapered head 11, the object is clamped under force.

[0027] In some embodiments of the present invention, a plurality of positioning grooves 18 are formed on the surface of the arc-shaped plate 9. A positioning pin 21 is slidably connected to the inner wall of the moving plate 17. The positioning pin 21 is adapted to the inner wall of the positioning groove 18.

[0028] By setting the positioning pin 21 and inserting and mating it with the positioning groove 18 at the corresponding position, the angle stability of the moving plate 17 is maintained.

[0029] In some embodiments of the present invention, an L-shaped plate 20 is fixedly connected to the surface of the support seat 3. The lower surface of the connecting block 19 is slidably connected to the upper surface of the L-shaped plate 20. By setting the L-shaped plate 20, the connecting block 19 is limited to prevent the connecting block 19 from rotating.

[0030] In some embodiments of the present invention, a hand-operated rotating wheel 5 is fixedly connected to the end of the first lead screw 8 away from the arc-shaped plate 9. By setting the hand-operated rotating wheel 5, the operator rotates the hand-operated rotating wheel 5 to drive the first lead screw 8 to rotate and adjust the position.

[0033] When this servo tailstock for a CNC lathe is in use, first, the horizontal position of the support base 3 on the base 1 is adjusted. The knob 7 can be rotated. The rotation of the knob 7 drives the second lead screw 23 to rotate. The rotation of the second lead screw 23 drives the slider 22 and the support base 3 as a whole to slide. By comparing the mark 13 with the scale line 12 for reference, the moving position of the support base 3 can be understood. Then, the positioning pin 21 can be slid upward. After the positioning pin 21 releases the limit on the arc-shaped plate 9, the moving plate 17 is manually rotated for angle adjustment. The rotation of the moving plate 17 causes the ball head 4 to rotate and adjust around the rotation axis 15. After the angle is adjusted, the positioning pin 21 is reinserted into the positioning groove 18 at the corresponding position. Then, the hand crank wheel 5 can be rotated to drive the first lead screw 8 to rotate. The L-shaped plate 20 ensures the horizontal movement of the connecting block 19, and pushes the arc-shaped plate 9 together with the moving plate 17 and the tapered head 11 as a whole to move, so that the tip of the tapered head 11 abuts against the center of the object to be clamped. With the above structure, during the process of turning a cylinder into a cone, the position of the servo tailstock and the angle of the tapered chuck are adjusted to ensure the stability during the turning process.
