Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and particularly relates to a numerical control machine tool provided with multi-directional drilling heads. Background Technique

[0002] A numerical control machine tool is a comprehensive tool that can be used for operations such as turning, drilling, and milling. It is often used more in industry or for metal processing. After the drill bit or the tool head is installed, the service life is relatively long, and it cannot be flexibly replaced. Moreover, the replacement operation is relatively cumbersome, and it cannot meet the operation requirements of drilling holes with multiple diameters.

[0003] The diameter of the drill bit of the existing numerical control machine tool is fixed and cannot meet the drilling requirements of different diameters. For example, a numerical control machine tool disclosed in the publication number CN214024819U includes a base, an X-axis lead screw drive, a Z-axis lead screw drive, and a Y-axis lead screw drive. An X-axis linear guide, a lead screw drive, and a workbench are installed on the base. A tool magazine support is installed on the side of the base, and a tool magazine is installed on the tool magazine support. A column is on the X-axis linear guide, and the column moves on the X-axis linear guide. A Z-axis linear guide and a double lead screw drive are installed on the column. A square box is fixed on the slider of the Z-axis linear guide, and the square box moves up and down along the Z-axis. Three sliders are installed on the front and back of the square box respectively. The lead screw drive is installed in the square box. Three Y-axis linear guides are installed on the sliding column, the sliding column is installed on the square box, and the sliding column moves back and forth along the Y-axis. The spindle box is installed at the front end of the sliding column, and the spindle is installed in the spindle box. A Z-axis balance bar is installed on the column, and the other end of the Z-axis balance bar is installed on the square box. The Z-axis balance bar reduces the load of the Z-axis lead screw through its own pulling force. The processing dimensions in this solution are fixed and cannot meet the drilling operations with multiple angles and multiple diameters.

[0004] Therefore, it is very necessary to invent a numerical control machine tool provided with multi-directional drilling heads to solve the above problems. Content of the Utility Model

The operating table 5 is slidably connected to the X-axis track 4. The main processing shaft 6 is fixedly connected to the base 2. The signal lamp 7 is installed on the main processing shaft 6. The driving mechanism 1 701 is slidably connected to the inner slide rail of the main processing shaft 6. The first drill bit 702 is connected to the driving mechanism 1 701. The auxiliary processing shaft 8 is fixedly connected to the main processing shaft 6. The connecting rod 801 is arranged on the auxiliary processing shaft 8. The cross shaft 802 is arranged on the connecting rod 801. The driving mechanism 2 803 is slidably connected to the cross shaft 802. The turntable 804 is connected to the driving mechanism 2 803. The second drill bit 805 and the third drill bit 806 are installed on the turntable 804.

[0025] When processing the workpiece on the operating table 5, the first drill bit 702 can be selected for processing, or the second drill bit 805 or the third drill bit 806 can be selected for processing to meet the processing requirements of drilling holes with different diameters.

[0026] The second drill bit 805 is arranged at the center of the turntable 804. There are multiple third drill bits 806. The multiple third drill bits 806 are annularly arranged around the center of the turntable 804, and the diameters of the multiple third drill bits 806 are different from each other. There are two auxiliary processing shafts 8. The two auxiliary processing shafts 8 are respectively arranged on both sides of the main processing shaft 6 and are symmetrically distributed in a mirror image. The driving mechanism 2 803 can slide along the direction of the cross shaft 802, and the driving mechanism 2 803 provides power for the rotation of the turntable 804.

[0027] When using the No. 2 drill bit 805 or the No. 3 drill bit 806, the diameter difference of each drill bit is 8 mm, and drills of various diameters can be processed.

[0028] The diameter of the No. 1 drill bit 702 is larger than that of the No. 2 drill bit 805, and the diameter of the No. 2 drill bit 805 is larger than that of multiple No. 3 drill bits 806.

[0030] The working principle of the present utility model:

[0031] Refer to the attached Figures 1-3 specification. When using the present utility model, first place the workpiece to be processed on the operation table 5, engage and fix it with the groove on the surface of the operation table 5. The drive mechanism I 701 and the No. 1 drill bit 702 can be selected to process it, or one of the auxiliary processing shafts 8 on both sides can be selected for processing;

[0032] Refer to the attached Figures 3-5 specification. When using the present utility model and processing through one of the auxiliary processing shafts 8 on both sides, different processing sizes of diameters can be achieved. The diameter of the No. 2 drill bit 805 is the largest, and the No. 3 drill bits 806 with gradually decreasing diameters can be selected in a clockwise order (the diameter difference between each No. 3 drill bit 806 is 8 mm);

[0033] The displacement of the workpiece in the X-axis and Y-axis directions is achieved through the sliding of the operation table 5, enabling the workpiece to be processed at multiple angles.
