Description

Technical Field

[0001] This utility model relates to the field of multi-axis linkage CNC milling machine technology, specifically a high-efficiency machining mechanism for multi-axis linkage CNC milling machines. Background Technology

[0002] Multi-axis CNC machining divides the motion coordinates (including the X, Y, and Z axes) of the tool and workpiece into the smallest unit quantities, i.e., the minimum displacement. The CNC system, according to the requirements of the workpiece program, moves each coordinate by several minimum displacements, thereby achieving the relative movement between the tool and the workpiece to complete the machining process. Compared to traditional machine tools, CNC machine tools offer higher machining accuracy and faster machining speeds and are widely used.

[0003] The existing multi-axis linkage CNC milling machine CN202220171859.9 processes multiple workpieces sequentially on a workpiece clamping plate via a spindle unit. Workpieces facing forward are clamped on one side of the workpiece clamping plate, while those facing backward are clamped on the other side. After machining one side of the workpiece clamping plate, the plate is flipped to machine the workpieces on the other side. After all workpieces are machined, the workpiece clamping plate is removed, and the workpieces on both sides are alternately clamped. The workpiece clamping plate is then reinstalled to machine the other side of the workpieces. Batch clamping improves production efficiency, and the workpiece clamping plate is easy to install and remove, and the installation is stable. However, the existing equipment has shortcomings: low tool changing efficiency, weak chip removal capability, and poor operational stability. Therefore, a high-efficiency machining mechanism for multi-axis linkage CNC milling machines is needed to solve these problems. Utility Model Content

[0020] Please see Figure 1-6 This utility model provides a technical solution: a high-efficiency machining mechanism for a multi-axis linkage CNC milling machine, comprising a machine body 1, an opening and closing sliding door 2, a coolant tank 3, a first suction pipe 4, a second suction pipe 5, a chuck 6, a three-axis mechanism 7, a horizontal support rod 8, a vertical support rod 9, a PLC controller 10, a tool holder 11, a liquid collection tank 12, a support tray 13, a drain 14, a tool head 15, an AC cradle frame 16, an aerosol system 17, a fixed plate 18, a tilting seat 19, an electric push rod 20, a tool holder 21, a mounting groove 22, a cover screen 23, a connecting hinge 24, and a support block 25.

The aerosol system 17 is a 4.5kPa mechanism. The first suction pipe 4 and the second suction pipe 5 integrate a water pump. The aerosol system 17 is inclinedly distributed on the inner wall of the body 1, which makes the coolant tank 3 easy and efficient to cool, and can spray efficiently through the aerosol system 17, with good cooling and dust removal effects.

[0021] The machine body 1 has mounting slots 22 on both sides of its inner wall, and a three-axis mechanism 7 is installed on the inner wall of the mounting slots 22.

The liquid collection tanks 12 are slidably pulled to the machine body 1, and the liquid collection tanks 12 are connected to the machine body 1 through the openings 14. The support tray 13 is a grid structure, and the support tray 13 moves along two axes with the machine body 1 through the AC cradle frame 16. The lower front and rear sides of the machine body 1 are inclined. The shape of the filter block 26 matches the shape of the inner wall of the liquid collection tank 12, and the filter block 26 is installed in a plug-in splicing manner with the liquid collection tank 12 through the support block 25. This makes it easy and stable to collect waste liquid in the liquid collection tank 12, and easy to filter through the filter block 26, which is convenient for secondary use and easy to use.

[0023] Support blocks 25 are fixedly connected to the upper ends of both sides of the inner wall of the liquid collection tank 12, and filter blocks 26 are placed on the upper ends of the support blocks 25.

A PLC controller 10 is installed at the lower end of the vertical support rod 9, and a connecting hinge 24 is installed on the rear side of the upper end of the PLC controller 10. The PLC controller 10 is rotatably connected to the machine body 1 in two stages through the horizontal support rod 8 and the vertical support rod 9. The cover screen 23 is flippedly connected to the PLC controller 10 through the connecting hinge 24. The outer wall of the cover screen 23 and the PLC controller 10 is an elastic structure, which makes it easy for the PLC controller 10 to be rotated in two stages and can be flipped open and closed for convenient protection. The cover screen 23 is installed on the other side of the connecting hinge 24.

[0025] Working principle: When using the high-efficiency machining mechanism of this multi-axis CNC milling machine, first connect the device to the power supply, then place the material on the support tray 13 and fix it. Next, control it through the PLC controller 10, then drive the cutter head 15 to move along three axes through the three-axis mechanism 7, and then drive the material to move along two axes through the AC cradle frame 16 and the support tray 13 to perform multi-axis machining. Moreover, during machining, efficient aerosol cooling can be achieved through the first suction duct 4 and the aerosol system 17, and the debris can be sprayed and washed away. The debris is also leaked out through the grid structure of the support tray 13 and then leaks into the machine through the drain 14. The coolant is then filtered through filter block 26 in the collection tank 12 and collected in the collection tank 12. The filtered coolant is then guided back to the coolant tank 3 through the second suction pipe 5 for reuse. When it is necessary to change the tool, the tool head 15 can be taken out through the tool holder 21, placed on the tool holder 11 for installation, and then the tool holder 11 can be rotated to the appropriate tool head 15 for clamping and replacement. After use, the cover screen 23 can be folded and closed with the hinge 24, and the PLC controller 10 can be attached to the machine body 1 for storage. This is the usage process of the high-efficiency machining mechanism of the multi-axis linkage CNC milling machine.
