Description

Technical Field

[0001] The invention relates to a gang tool type machine tool, in particular to a gang tool type machine tool with Z-direction interpolation. Background Art

[0002] Interpolation is the process of determining the tool motion trajectory by using data point densification in the CNC system of machine tools. It is a method of coordinating the drive axes of machine tools. At present, most machine tools use the Y axis as the interpolation axis to interpolate the X direction. For example, the Chinese invention application CN114393405A discloses a milling machine tool with an interpolation Y axis, which improves the cutting accuracy by using the interpolation Y axis structure.

[0003] However, this type of interpolation structure mainly uses the X-axis slide to realize feeding, and the Y-axis slide to interpolate in the X direction, and the interpolation direction is perpendicular to the spindle direction. This structure is applicable to the rotating turret that can realize automatic tool change, but it may not be applicable to the row-type power head. Specifically, since the row-type power head needs to rely on the slide for tool change and cannot change tools autonomously, and its multiple tools are arranged on a plane perpendicular to the spindle, if it is used for the X-direction interpolation structure, the X-axis slide is used as both the feed axis and the tool change axis. In order to realize the processing of tools in different positions, it is necessary to greatly increase the length of the X-axis slide, resulting in a reduction in the rigidity of the X-axis slide, which is not conducive to the control of the processing force. In addition, if the milling cutter of the power head is steerable, it is also necessary to provide a rotation space for the milling cutter, and the rigidity of the position of some shorter milling cutters is further reduced. Summary of the invention

[0004] The technical solution of the present invention is aimed at the above situation. In order to solve the above problem, a Z-direction interpolation gang tool machine tool is provided. The gang tool machine tool comprises: a spindle arranged along a spindle direction, a gang tool power head, a Y-axis slide, an X-axis slide and a Z-axis slide. The power head comprises: a power head bracket, a steering mechanism and a plurality of horizontally arranged milling cutter shafts. The power head bracket is arranged on the Y-axis slide to control the power head to move along a Y direction. The Y-axis slide is arranged on the X-axis slide to control the power head to move along an X direction. The X-axis slide is arranged on the Z-axis slide to control the power head to move along a Z direction. The spindle direction is parallel to the Z direction. The Z direction is parallel to the A horizontal plane is parallel, characterized in that: the angle between the Y direction and the Z direction is greater than 0° and less than 90°, and the Y direction and the Z direction are both perpendicular to the X direction; the power head bracket has a turning space, and the turning space has a first space and a second space, the first space is located above the second space, the Z direction width of the first space is greater than the Z direction width of the second space and a part of the first space is farther away from the main axis than the second space, the steering mechanism is arranged on the power head bracket, and multiple milling cutter axes are arranged on the steering mechanism to control the multiple milling cutter axes to turn around a rotating axis perpendicular to the XZ plane, and the multiple milling cutter axes are located in the steering space.

[0005] Among them, since the angle between the Y direction and the Z direction is greater than 0° and less than 90° (that is, the Y direction is not a vertical direction), an inverted triangle structure is formed, thereby enhancing the rigidity of the Y-axis slide and better controlling the processing force.

[0006] Among them, since the Z direction is the feed direction, the Y-axis slide is used to realize the interpolation operation in the Z direction, and the X-axis slide and the Y-axis slide are used together for tool changing and tool setting operations. Therefore, it can be used for a row-type power head to avoid the situation where the X-axis slide is too long, ensure the overall rigidity, and smoothly carry out processing and tool changing operations.

[0007] Among them, the width of the steering space of the power head bracket in the Z direction gradually narrows from top to bottom, which is consistent with the inclination direction of the Y-axis slide. The longer milling cutter shaft can be placed in a wider position, and the shorter cutter shaft can be placed in a narrower position, and one end of multiple milling cutter shafts are flush. In this way, the distance between the Y-axis slide and the center of gravity of milling cutter shafts of different lengths is smaller, so that milling cutter shafts of different lengths can obtain good rigidity.

[0008] Furthermore, the steering mechanism includes: a steering seat, a steering reducer and a steering motor, wherein the steering seat and the steering motor are connected via the steering reducer, and a plurality of milling cutter shafts are arranged on the steering seat. The steering motor controls the steering of the steering seat before or during the machining operation.

[0009] Furthermore, the multiple milling cutter shafts include: multiple barrel shafts and multiple electric spindles, the power head also includes: multiple gears and milling motors, the multiple barrel shafts are arranged in at least one vertical row and are respectively fixed with multiple gears, two adjacent gears are meshed with each other, the motor shaft of the milling motor is connected to a barrel shaft, and the multiple electric spindles are arranged in at least one vertical row. Among them, the rotation rate of the barrel shaft assembly is low, generally 3000 to 4000 rpm. When it is necessary to perform a processing technology with high resistance and low precision requirements such as tapping, the barrel shaft assembly can be used to control the rotation of the milling cutter; the rotation rate of the electric spindle is high, which can reach 10000 to 50000 rpm. When it is necessary to perform a processing technology with low resistance and high precision requirements such as chamfering, the electric spindle can be used to control the rotation of the milling cutter.

[0010] Furthermore, the turning space is in a prism shape and one surface of the turning space is parallel to the Y direction, at least two electric spindles have different lengths, and each row of electric spindles are arranged from top to bottom in descending order of length.

Among them, the above-mentioned gang tool type machine tool can perform milling operations, drilling operations and turning operations, and has a wide range of applications. In addition, the drilling tool cylinder and turning tool holder are arranged on the power head bracket instead of the steering mechanism, which can ensure the rigidity of the drilling tool and the turning tool.

[0012] Furthermore, the angle between the X direction and the horizontal plane is greater than 0° and less than 90°. The moving direction of the X-axis slide is set to be inclined relative to the horizontal plane, which can enhance the rigidity of the X-axis slide and better control the processing force.

[0013] Furthermore, the angle between the Y direction and the Z direction is 30°, and the angle between the X direction and the horizontal plane is 45°. This angle layout is relatively reasonable, and avoids the Y-axis slide occupying a large space in the vertical direction.

[0014] Furthermore, the Y-axis slide includes: a Y-axis support plate, a Y-axis motor, a Y-axis screw rod, a Y-axis nut, a Y-axis guide rail and a Y-axis slider, wherein the Y-axis support plate is arranged on the X-axis slide, the Y-axis motor and the Y-axis guide rail are both arranged on the Y-axis support plate, the motor shaft of the Y-axis motor is connected to the Y-axis screw rod, the Y-axis screw rod is meshed with the Y-axis nut, the Y-axis slider is arranged on the Y-axis guide rail and can move relative to the Y-axis guide rail, the Y-axis screw rod and the Y-axis guide rail are both arranged along the Y direction, and the Y-axis nut and the Y-axis slider are both fixed to the power head support. Among them, the movement of the power head can be made more stable through the cooperation of the Y-axis guide rail and the Y-axis slider.

[0015] Furthermore, the X-axis slide includes: an X-axis support plate, an X-axis motor, an X-axis lead screw, an X-axis nut, an X-axis guide rail and an X-axis slider, wherein the X-axis support plate is arranged on the Z-axis slide, the X-axis motor and the X-axis guide rail are both arranged on the X-axis support plate, the motor shaft of the X-axis motor is connected to the X-axis lead screw, the X-axis lead screw is meshed with the X-axis nut, the X-axis slider is arranged on the X-axis guide rail and can move relative to the X-axis guide rail, the X-axis lead screw and the X-axis guide rail are both arranged along the X direction, and the X-axis nut and the X-axis slider are both fixed to the Y-axis support plate. The cooperation between the X-axis guide rail and the X-axis slider can make the movement of the power head more stable.

[0016] Furthermore, the Z-axis slide includes: a Z-axis base, a Z-axis motor, a Z-axis screw rod, a Z-axis nut, a Z-axis guide rail and a Z-axis slider, wherein the Z-axis motor and the Z-axis guide rail are both arranged on the Z-axis base, the motor shaft of the Z-axis motor is connected to the Z-axis screw rod, the Z-axis screw rod is meshed with the Z-axis nut, the Z-axis slider is arranged on the Z-axis guide rail and can move relative to the Z-axis guide rail, the Z-axis screw rod and the Z-axis guide rail are both arranged along the Z direction, and the Z-axis nut and the Z-axis slider are both fixed to the X-axis bracket plate.

In the present embodiment, the plurality of milling cutter axes arranged on the steering mechanism 22 are arranged in two vertical rows, and the vertical row means that each row of milling cutter axes is arranged in the up-down direction. Of course, in other embodiments, the plurality of milling cutter axes may also be arranged in other ways.

[0029] It is worth mentioning that since the main axis direction C is parallel to the Z direction, the main axis direction C is also parallel to the horizontal plane S1 and the vertical plane S2, the angle between the Y direction and the main axis direction C is also greater than 0° and less than 90°, and the X direction is also perpendicular to the main axis direction C.

[0030] Before machining, the milling cutter is fixed on the milling cutter shaft, and the Y-axis slide 3 and the X-axis slide 4 cooperate to control the power head 2 to move in the Y direction and the X direction to complete the tool setting operation; in addition, when switching tools, the power head 2 is also controlled by the Y-axis slide 3 and the X-axis slide 4 to achieve tool setting operations for different tools. When it is necessary to control the direction of the milling cutter, the steering mechanism 22 can be used to control multiple milling cutter shafts to turn along the bidirectional arrow S, thereby changing the machining angle.

[0031] During milling, the workpiece is fixed and the milling cutter is controlled to rotate. The Z direction is used as the feed direction. The Y-axis slide 3 is used as the interpolation axis to control the power head 2 to move along the Y direction and interpolate in the Z direction (that is, to achieve Z-direction interpolation). At the same time, the Y-axis slide 3 and the X-axis slide 4 cooperate in real time to control the tool position, so as to process the predetermined workpiece shape.

[0032] For details, please continue to refer to Figures 3-4 As shown, the steering mechanism 22 includes: a steering seat 221, a steering reducer 222 and a steering motor 223. The steering seat 221 and the steering motor 223 are connected through the steering reducer 222, and a plurality of milling cutter shafts are arranged on the steering seat 221. When the milling cutter needs to be controlled to turn, the steering motor 223 controls the steering seat 221 to rotate through the steering reducer 222.

The motor shaft of the milling motor 26 is connected to one barrel shaft 23, and the multiple electric spindles 24 are arranged in at least one vertical row. The barrel shaft 23 and the electric spindle 24 are both used to install the milling cutter. When the barrel shaft assembly 23 is working, the milling motor 26 controls one of the barrel shafts 23 to rotate, and drives the remaining barrel shafts 23 to rotate through the multiple gears 25; when the electric spindle 24 is working, it only needs to be powered on to control the rotation of the milling cutter.

At least two electric spindles 24 have different lengths, and a row of electric spindles 24 are arranged from top to bottom in descending order of length. That is, the Z-direction width of the turning space 210 gradually decreases from top to bottom, and the longer electric spindle 24 is located above the shorter electric spindle 24.

The turning tool slots of the drilling tool cylinder 25 and the turning tool holder 26 are used to install the drilling tool and the turning tool respectively.

Specifically, the angle between the Y direction and the Z direction is 30°, and the angle between the X direction and the horizontal plane S1 is 45°.
