[0002] The universal angle milling head, also known as the universal angle head or the universal milling head, is a machine tool accessory. Its main function is to enable the rotation center line of the tool to form a certain angle with the rotation center line of the spindle after the machine tool is installed, so as to machine the workpiece. This design greatly increases the machining range and adaptability of the machine tool, and can complete some machining that is difficult to achieve by traditional methods without changing the structure of the machine tool.

[0003] For example, the patent specification of the existing Chinese patent (publication number: CN215698299U) discloses a universal angle milling head for boring and milling CNC machine tools, including a device base, a connecting seat is arranged at the upper end of the device base, a connecting block is arranged at the upper end of the connecting seat, a rotating shaft is arranged at the center position of the upper end surface of the connecting seat, and the rotating shaft penetrates through the inside of the connecting block.

[0004] However, in the implementation of the related technology, it is found that the above-designed universal angle milling head for boring and milling CNC machine tools has the following problems: Although the universal angle milling head for boring and milling CNC machine tools can achieve universal adjustment, most of them realize universal adjustment through self-rotation or nodding rotation, which is rather inconvenient in this process. In view of this, a universal angle milling head for boring and milling CNC machine tools is provided to overcome the above defects. Content of the Utility Model

[0024] Referring to Figures 1-4 , a universal angle milling head for boring and milling CNC machine tools provided by the utility model includes a milling head body 1 and an adjusting box 2. The adjusting box 2 is located on one side of the milling head body 1. A connecting piece 4 is fixedly installed on one side of the milling head body 1. A limiting cavity is arranged in the adjusting box 2, and an adjusting ball 3 is rotatably arranged in the limiting cavity. One end of the connecting piece 4 far from the milling head body 1 is fixedly connected with the adjusting ball 3. A positioning component is further arranged in the adjusting box 2 for positioning the adjusting ball 3 after adjustment. The limiting cavity includes an adjusting cavity 5 and an adjusting port 6, and the adjusting cavity 5 and the adjusting port 6 are communicated. The adjusting ball 3 is rotatably arranged in the adjusting cavity 5 and the adjusting port 6;

[0025] The positioning component includes a sliding plate 7 which is slidably connected in the adjusting cavity 5. A positioning member 8 is fixedly installed at the bottom of the sliding plate 7. The positioning member 8 is in abutting cooperation with the adjusting ball 3. Two springs 11 are symmetrically arranged at the top of the sliding plate 7. The other ends of the springs 11 are installed on the inner top wall of the adjusting cavity 5. The positioning component further includes a driving component which abuts against the sliding plate 7. The driving component includes a threaded screw rod 9 and a threaded hole 10. The threaded hole 10 is opened on the adjusting box 2. The threaded screw rod 9 is threadedly inserted into the threaded hole 10 and abuts against the sliding plate 7. A push sphere 12 is fixedly installed at the bottom end of the threaded screw rod 9. The push sphere 12 abuts against the sliding plate 7.

[0026] During specific implementation, hold the milling head body 1 and drive the connecting member 4 and the adjusting ball 3 to rotate at a suitable angle in the adjusting cavity 5 and the adjusting port 6. Then rotate the threaded screw rod 9 so that the threaded screw rod 9 drives the push sphere 12 to move downward while rotating. During this process, the push sphere 12 will push the sliding plate 7 and the threaded screw rod 9 to move downward and stretch the spring 11 until the positioning member 8 abuts tightly against the adjusting ball 3, thus positioning the adjusting ball 3, and then the milling head body 1 can be conveniently adjusted at any angle. This operation only needs one step to complete, improving the use effect.

[0027] As a further implementation of the above technical solution: the number of positioning components is two, and the two positioning components are symmetrically installed in the adjusting box 2. The setting of the two positioning components can further improve the positioning force on the adjusting ball 3 and further increase its stability.

[0028] As a further implementation of the above technical solution: a telescopic rod 13 is further arranged at the top of the sliding plate 7. The piston end of the telescopic rod 13 is installed on the inner top wall of the adjusting cavity 5. The number of the telescopic rod 13 is the same as that of the spring 11. By arranging the telescopic rod 13, when the sliding plate 7 moves, the piston end of the telescopic rod 13 can be telescoped, which can limit the moving direction of the sliding plate 7, thus improving the stability.

[0029] As a further implementation of the above technical solution: a plurality of handles 14 are arranged at one end of the threaded screw rod 9 away from the push sphere 12. The outer surface of the handle 14 is provided with anti-slip patterns. It can increase the friction between the human hand and the threaded screw rod 9, thus helping to solve the problem of slipping when rotating the threaded screw rod 9.

[0030] As a further implementation of the above technical solution: positioning plates 15 are fixedly installed on both sides of the adjusting box 2. A plurality of positioning screws 16 are threadedly inserted into the positioning plates 15. Through the cooperation of the positioning plates 15 and the positioning screws 16, the adjusting box 2 can be conveniently installed on the milling machine.

[0031] Working principle:

[0032] When using the present utility model, first install the adjustment box 2 on the milling machine through the positioning plate 15 and the positioning screw 16. Subsequently, when it is necessary to adjust any angle of the milling head body 1, first hold the milling head body 1 to drive the connecting member 4 and the adjusting ball 3 to rotate an appropriate angle in the adjustment cavity 5 and the adjustment port 6. Then rotate the threaded lead screw 9, so that the threaded lead screw 9 drives the push ball body 12 to move downward while rotating. During this process, the push ball body 12 will push the slide plate 7 and the threaded lead screw 9 to move downward and stretch the spring 11 until the positioning member 8 is tightly abutted against the adjusting ball 3, then the adjusting ball 3 can be positioned, thus facilitating the adjustment of any angle of the milling head body 1 and improving the use effect;

[0033] It should be noted that by providing the telescopic rod 13, when the slide plate 7 moves, the piston end of the telescopic rod 13 can be telescoped, which can limit the movement direction of the slide plate 7, thereby improving the stability.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
