[0002] The milling head in a CNC gantry machining center is mainly used to expand the machining range of the machine tool, improve machining accuracy and efficiency, and realize multi-process composite machining. Its core functions are reflected in the following aspects: by changing the direction of the tool axis, the milling head can increase the machining range of the machine tool, making it possible to complete machining that is difficult to do by traditional methods. At the same time, it reduces the number of times the workpiece is repeatedly clamped, ensures cutting stability, reduces workpiece deformation, and improves machining accuracy. Rotating the milling head can adjust the relative angle between the tool and the workpiece, realizing milling machining of inclined surfaces at any angle.

[0003] When using the existing milling head rotating device for CNC gantry machining centers, the function of the milling head rotating device is to adjust the relative angle between the tool and the workpiece by rotating the milling head. The existing milling head rotating device is connected by a mounting tube during installation. However, the mounting tube cannot be easily disassembled and reassembled, which leads to the problem of not being able to quickly replace mounting tubes of different sizes. Utility Model Content

[0009] Preferably, the threaded sleeve has grooves on both sides, and one end of the positioning block is inserted into the groove of the threaded sleeve.

[0010] Preferably, the fixing screw is connected to one end surface of the mounting tube, and the threaded sleeve and the fixing screw are connected by threads.

[0011] Preferably, the device body has a limiting structure connected to both sides of its surface. The limiting structure includes a fixing frame, a positioning plate sleeved on the outer wall of the fixing frame, an adjusting screw inserted inside the top of the positioning plate, and a fixing rod rotatably connected to the bottom outer surface of the adjusting screw.

[0012] Preferably, the positioning plate has through slots on both sides of its top end, and the fixing frame is configured as an L-shaped structure, with the top end of the fixing frame inserted into the through slots of the positioning plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By inserting the positioning blocks connected to both sides of the gasket surface into the groove of the threaded sleeve, and then inserting one end of the guide rod into the installation tube, the movement of the threaded sleeve is guided.

[0025] A milling head rotation device for a CNC gantry machining center includes:

[0026] The device body 1 includes a device body 11. The surface of the device body 11 is provided with an installation tube 12. The internal material of the installation tube 12 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application, so no further details are made.

[0027] The assembly structure 2 is attached to the surface of the equipment body 11. The assembly structure 2 includes a gasket 21. Positioning blocks 22 are connected to both sides of the surface of the gasket 21. A threaded sleeve 23 is fitted on the outer wall of the positioning block 22. A fixing screw 24 is rotatably connected inside the threaded sleeve 23. One end of the fixing screw 24 is connected to a guide rod 25.

[0028] Furthermore, one end of the fixing screw 24 is connected to the surface of the equipment body 11, and the gasket 21 is sleeved on the outer surface of the fixing screw 24, so that the gasket 21 fills the space between the equipment body 11 and the threaded sleeve 23 to buffer the connection and make the two make flexible contact.

[0029] Furthermore, grooves are provided on both sides of the threaded sleeve 23, and one end of the positioning block 22 is inserted into the groove of the threaded sleeve 23, so that the positioning block 22 is positioned by the groove of the threaded sleeve 23, thereby positioning the gasket 21 and the threaded sleeve 23.

[0030] Furthermore, the fixing screw 24 is connected to one end surface of the mounting tube 12, and the threaded sleeve 23 and the fixing screw 24 are connected by threads, thereby fixing the equipment body 11 and the mounting tube 12 by connecting the threaded sleeve 23 and the fixing screw 24 through threads.

[0031] Furthermore, the two sides of the surface of the equipment body 11 are connected to a limiting structure 3. The limiting structure 3 includes a fixed frame 31. A positioning plate 32 is sleeved on the outer wall of the fixed frame 31. An adjusting screw 33 is inserted inside the top of the positioning plate 32. A fixing rod 34 is rotatably connected to the bottom outer surface of the adjusting screw 33. This allows the angle of the threaded sleeve 23 to be controlled by the positioning plate 32, preventing it from rotating.

[0032] Furthermore, the top two sides of the positioning plate 32 are provided with through slots, and the fixing frame 31 is set with an L-shaped structure. The top of the fixing frame 31 is inserted into the through slot of the positioning plate 32, so that the fixing frame 31 is positioned by the through slot of the positioning plate 32, thereby using the fixing frame 31 to move and limit the positioning plate 32.

[0033] Furthermore, a through hole is provided at the center of the top surface of the positioning plate 32, and a threaded groove is provided on the top surface of the fixing rod 34. The bottom end of the fixing rod 34 is connected to the surface of the fixing screw 24. The bottom end of the adjusting screw 33 passes through the through hole of the positioning plate 32 and is rotatably connected to the inside of the threaded groove of the fixing rod 34. The positioning plate 32 and the fixing rod 34 are connected by adjusting the screw 33, thereby limiting the positioning plate 32.

[0034] Working principle: When assembling the milling head rotation device of the CNC gantry machining center, the positioning blocks 22 connected to both sides of the surface of the shim 21 are inserted into the groove of the threaded sleeve 23. Then, one end of the guide rod 25 is inserted into the mounting tube 12 to guide the movement of the threaded sleeve 23. The angle of the threaded sleeve 23 is rotated so that the threaded sleeve 23 is rotatably connected to the outer surface of the fixed screw 24, and the shim 21 is sleeved on the outer wall of the fixed screw 24. The shim 21 is used to create a gap between the equipment body 11 and the threaded sleeve 23, so that the two are in flexible contact, thereby realizing the rapid assembly between the equipment body 11 and the mounting tube 12.

[0035] When limiting the rotation of the milling head in a CNC gantry machining center, the top of the fixed frame 31 is inserted into the through slot of the positioning plate 32, so that the fixed frame 31 moves and limits the positioning plate 32. After the threaded sleeve 23 is installed, the bottom end of the adjusting screw 33 is passed through the through hole of the positioning plate 32 and rotated into the threaded groove of the fixed rod 34 to limit the positioning plate 32. The positioning plate 32 is used to control the angle of the threaded sleeve 23 so that it cannot rotate.
