Description

Technical Field

[0001] This utility model belongs to the field of machining lathe technology, specifically relating to a CNC machine tool with interpolation Y-axis function. Background Technology

[0002] As a crucial tool in the machining industry, the precision and efficiency of lathes directly impact the quality and effectiveness of the entire machining process. The axes of a lathe are one of its core components, controlling the movement of the cutting tool. The X-axis and Z-axis are the two most fundamental axes on a lathe, controlling the tool's movement in the horizontal and vertical directions, respectively. The X-axis typically moves laterally, controlling the workpiece's feed motion on the lathe, while the Z-axis typically moves longitudinally, controlling the workpiece's axial feed motion. The movements of these two axes form most turning profiles and are also the two most frequently used axes in programming. In traditional lathe machining, movement control is usually limited to only the X and Z axes. For machining complex shapes or high-precision workpieces, existing two-axis lathes have certain limitations. In actual machining processes, factors such as tool wear and machine tool thermal deformation can affect machining accuracy, requiring compensatory adjustments. Utility Model Content

[0003] To address the aforementioned problems and technical requirements, this invention provides a CNC machine tool with interpolation Y-axis function. By increasing motion control in the Y-axis direction, the machining accuracy and flexibility of the lathe are improved, while also enabling real-time detection and compensation of machining errors.

[0004] The technical solution of this utility model is as follows: A CNC machine tool with Y-axis interpolation function includes a bed, a spindle box, a tailstock assembly, a Z-axis linear module, a Y-axis interpolation mechanism, an X-axis linear module, and a power turret. The spindle box and tailstock assembly are respectively provided on both sides of the top surface of the bed. The tailstock assembly can slide relative to the spindle box. The area between the spindle box and the tailstock assembly is a workpiece clamping area. The Z-axis linear module is provided along the workpiece clamping area on the top surface of the bed. The direction of the Z-axis linear module is parallel to the axis of the spindle box. The Y-axis interpolation mechanism is connected to the Z-axis linear module. The movement direction of the Y-axis interpolation mechanism is perpendicular to the axis of the spindle box. The top of the Y-axis interpolation mechanism is an inclined surface. The X-axis linear module is set on the inclined surface. The power turret is connected to the X-axis linear module. The X-axis linear module drives the power turret to move downward along the X-axis. The Y-axis interpolation mechanism can drive the power turret to move up and down in the vertical direction on the basis of the X-axis movement. In this solution, the power turret can move freely in three directions: X-axis, Y-axis, and Z-axis, which improves the machining range and flexibility. The movement in the Z-axis direction is to align the workpiece with the machining position on the circumferential or end face. The movement in the X-axis determines the cutting depth of the workpiece, while the feed in the Y-axis can be linked with the X-axis, so that the power turret can not only extend and retract but also float up and down at the same time, enabling the machining of more complex part shapes.

[0005] Furthermore, the Y-axis interpolation mechanism includes a base plate, an inclined plane support, a Y-axis motor, a Y-axis slide rail, and a Y-axis ball screw. The base plate is equipped with the Y-axis slide rail and the Y-axis ball screw, and the Y-axis motor is located on the side of the base plate. The Y-axis motor is connected to the Y-axis ball screw. The bottom surface of the inclined plane support is connected to the Y-axis slide rail and the Y-axis ball screw. The Y-axis motor can drive the inclined plane support to slide back and forth along the Y-axis slide rail. Since the inclined plane support can slide back and forth along the Y-axis, when the inclined plane support is pushed forward, the power turret slides upward along the X-axis, which can raise the power turret in the vertical direction, thus raising the tool. Conversely, when the inclined plane support is retracted, the power turret slides downward along the X-axis, which can reduce the machining height of the tool. Through the linkage operation of the X-axis and Y-axis, a more flexible milling effect is achieved.

[0006] Furthermore, the Z-axis linear module includes a Z-axis motor, a Z-axis guide rail, and a Z-axis ball screw. The Z-axis guide rail and the Z-axis ball screw are arranged parallel to the axis of the spindle box on the top surface of the bed. The Z-axis motor is fixedly connected to the screw end of the Z-axis ball screw, and the nut of the Z-axis ball screw is fixedly connected to the bottom surface of the base plate. The Z-axis motor drives the Y-axis interpolation mechanism to reciprocate along the Z-axis guide rail.

[0007] Furthermore, the X-axis linear module includes an X-axis slide rail, an X-axis motor, and an X-axis ball screw. The X-axis slide rail and X-axis ball screw are arranged along the inclined surface of the top of the inclined support. The X-axis motor is fixedly connected to the end face of the inclined support and is connected to the screw end of the X-axis ball screw. The bottom surfaces of the power turret are slidably connected to the X-axis slide rail, and the middle of the bottom surface of the power turret is fixedly connected to the nut of the X-axis ball screw. The X-axis motor drives the power turret to reciprocate along the inclined X-axis. The power turret has two operating modes: one is that the Y-axis is stationary, and the power turret can only extend and retract along the X-axis, which prevents height fluctuation and is suitable for machining simple-shaped workpieces; the other is that the X-axis and Y-axis are linked for machining, allowing the power turret to move over a wider range and is suitable for machining complex-shaped workpieces.

[0008] Furthermore, the power turret includes a protective shell, a rotary tool post, a servo motor, and a drive gear. The bottom of the protective shell is connected to the X-axis ball screw, and the rotary tool post and drive gear are rotatably connected to the side of the protective shell. The servo motor is installed inside the protective shell, and an output gear is installed at the output end of the servo motor. A gear ring is installed on the outer circumference of the rotary tool post. The output gear and the rotary tool post are connected by a drive gear. The servo motor drives the rotary tool post to rotate forward or backward.

[0009] Furthermore, the rotary tool holder is equipped with a ring of tool holders. The clamping direction of the tool holders is either parallel to or perpendicular to the spindle box axis, and different milling tools are mounted on the tool holders. By setting tool holders on the rotary tool holders, when the milling tools clamped on the tool holders are perpendicular to the spindle box axis, circumferential milling of the workpiece can be performed; when the milling tools clamped on the tool holders are parallel to the spindle box axis, end face milling of the workpiece can be performed. This arrangement is compatible with different clamping methods and can adapt to different machining needs.

[0010] Furthermore, the tailstock assembly includes a tailstock and a tailstock linear module. The tailstock linear module is disposed on the top surface of the bed, and its setting direction is parallel to the axis of the spindle box. The tailstock is connected to the tailstock linear module. A rear center is provided on the end face of the tailstock opposite to the spindle box. The tailstock linear module can drive the tailstock to slide forward, so that the rear center hits the end of the workpiece to be processed.

[0011] Furthermore, the spindle box is equipped with a chuck, which can clamp the workpiece, and the rear center is set to correspond to the chuck axis.

[0012] When the power turret is machining the end face of the workpiece, the other end of the workpiece is clamped by the chuck, and the tailstock retracts to leave a workpiece clamping area, which facilitates the forward feeding of the power turret. When the power turret is machining the circumferential surface of the workpiece, the tailstock's rear center must cooperate with the chuck. The chuck clamps one end, and the center of the other end face is pressed by the rear center. This fixes the workpiece's axis, keeping the axis stationary during milling and improving machining accuracy.

[0013] Furthermore, the bed is made of cast iron, and the bottom of the bed is equipped with multiple leveling feet. The cast iron bed has sufficient strength and rigidity to withstand the dynamic loads and impacts generated by the machine tool during high-speed machining, and the leveling feet can level the bed.

[0014] Furthermore, the tailstock linear module is equipped with a sloping baffle above it, and a chip removal window penetrating the machine bed is located below the workpiece clamping area. The chips generated during machining are discharged downwards through the sloping baffle and the chip removal window. The sloping baffle blocks the machining chips, preventing them from falling onto the tailstock linear module and protecting its smooth operation.

[0015] The beneficial effects of this utility model are as follows: This machine tool is equipped with an interpolation Y-axis function, enabling the power turret to move simultaneously along the X, Y, and Z axes, achieving multi-axis linkage machining. It can process workpieces with complex shapes. The axes of the machine tool are all equipped with high-precision ball screws and guideways, which can ensure high-precision machining and reduce scrap rate. The rotary tool post in the power turret can be equipped with multiple tool holders, which can hold different tools, including turning tools, milling cutters, and rotary heads. The diversity of the number and types of tools can adapt to different machining needs, allowing multiple complex processes such as turning, milling, drilling, tapping, and reaming to be easily completed in one clamping. It has high machining efficiency, strong rigidity, and excellent stability. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-7 The present invention discloses a CNC machine tool with Y-axis interpolation function, comprising a bed 1, a spindle head 2, a tailstock assembly 3, a Z-axis linear module 4, a Y-axis interpolation mechanism 5, an X-axis linear module 6, and a power turret 7. The spindle head 2 and tailstock assembly 3 are respectively arranged on both sides of the top surface of the bed 1. The tailstock assembly 3 can slide relative to the spindle head 2. A workpiece clamping area 11 is located between the spindle head 2 and the tailstock assembly 3. The Z-axis linear module 4 is arranged along the workpiece clamping area 11 on the top surface of the bed 1. The direction is parallel to the axis of the spindle box 2. The Z-axis linear module 4 is connected to the Y-axis interpolation mechanism 5. The movement direction of the Y-axis interpolation mechanism 5 is perpendicular to the axis of the spindle box 2. The top of the Y-axis interpolation mechanism 5 is an inclined surface. The X-axis linear module 6 is set on the inclined surface. The power turret 7 is connected to the X-axis linear module 6. The X-axis linear module 6 drives the power turret 7 to move downward along the X-axis.

A chuck 21 is provided on the spindle box 2, which can clamp the workpiece. The rear center 33 is correspondingly arranged with the chuck axis. When the power turret 7 is machining the end face of the workpiece, the other end of the workpiece is clamped by the chuck, and the tailstock 31 retracts, leaving the workpiece clamping area 11 to facilitate the forward feed of the power turret 7. When the power turret 7 is machining the circumferential surface of the workpiece, the rear center 33 of the tailstock 31 must cooperate with the chuck 21. The chuck 21 clamps one end, and the center of the other end face is pressed by the rear center 33. This can fix the axis of the workpiece, so that the axis remains stationary when the workpiece rotates for milling, thereby improving the machining accuracy.

[0028] A sloping baffle 34 is provided above the tailstock linear module 32, and a chip removal window 13 penetrating the machine bed is provided below the workpiece clamping area 11.

[0029] The Y-axis interpolation mechanism 5 includes a base plate 51, an inclined bracket 52, a Y-axis motor 53, a Y-axis slide rail 54, and a Y-axis ball screw 55. The base plate 51 is provided with the Y-axis slide rail 54 and the Y-axis ball screw 55. The Y-axis motor 53 is provided on the side of the base plate 51 and is connected to the Y-axis ball screw 55.

The X-axis linear module 6 includes an X-axis slide rail 61, an X-axis motor 62, and an X-axis ball screw 63. The X-axis slide rail 61 and the X-axis ball screw 63 are arranged along the inclined surface of the top of the inclined bracket 52. The X-axis motor 62 is fixedly connected to the end face of the inclined bracket 52. The X-axis motor 62 is connected to the screw end of the X-axis ball screw 63. The bottom surfaces of the power turret 7 are slidably connected to the X-axis slide rail 61 on both sides. The middle part of the bottom surface of the power turret 7 is fixedly connected to the nut of the X-axis ball screw 63. The X-axis motor 62 drives the power turret 7 to reciprocate along the inclined X-axis.

[0030] The power turret 7 includes a protective shell 71, a rotary tool holder 72, a servo motor 73, and a drive gear 74. The bottom of the protective shell 71 is connected to the X-axis ball screw 63. The rotary tool holder 72 and the drive gear 74 are rotatably connected to the side of the protective shell 71. The servo motor 73 is housed inside the protective shell 71, and an output gear 75 is provided at the output end of the servo motor 73. A gear ring 722 is provided on the outer circumference of the rotary tool holder 72. The output gear 75 and the rotary tool holder 72 are meshed and connected through the drive gear 74. The servo motor 73 drives the rotary tool holder 72 to rotate forward or backward. A tool holder 721 is provided on the rotary tool holder 72. The clamping direction of the tool holder 721 is parallel to or perpendicular to the axis of the spindle box. Different milling tools are mounted on the tool holder 721. A tool holder 721 is set on the rotary tool holder 72. When the milling tool clamped on the tool holder 721 is perpendicular to the axis of the spindle box 2, it can perform circumferential milling on the workpiece. When the milling tool clamped on the tool holder 721 is parallel to the axis of the spindle box, it can perform end face milling on the workpiece. It is compatible with different clamping methods and can adapt to different processing needs.

[0031] The bed 1 is made of cast iron, and the bottom of the bed 1 is provided with multiple leveling feet 12. The cast iron bed 1 has sufficient strength and rigidity to withstand the dynamic loads and impacts generated by the machine tool during high-speed machining, and the leveling feet 12 can level the bed.

[0032] The operating principle of this utility model is as follows: The workpiece is clamped onto the chuck 21. Depending on the machining area of ​​the workpiece, the tailstock 31 is tightened. If machining the circumferential surface of the workpiece, the tailstock 31 slides forward, and the rear center 33 tightens against the end face of the workpiece. If machining the end face of the workpiece, the tailstock 31 slides backward, creating machining space for the tool. The power turret 7 has two operating modes: one where the Y-axis remains stationary and the power turret 7 can only extend and retract along the X-axis, preventing height fluctuations and making it suitable for machining workpieces with simple shapes. Another method is X-axis and Y-axis linkage machining. Since the inclined support 52 can slide back and forth along the Y-axis, when the inclined support 52 is pushed forward, the power turret 7 slides upward along the X-axis, which can raise the power turret 7 vertically and raise the tool. Conversely, when the inclined support 52 is retracted, the power turret 7 slides downward along the X-axis, which can reduce the machining height of the tool. Through the linkage operation of the X-axis and Y-axis, a more flexible milling effect is achieved, and the power turret 7 moves a wider range, which is suitable for machining workpieces with complex shapes.

Any variations and substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
