Description

Technical Field

[0001] This utility model relates to the field of machine tools, and in particular to an anti-winding milling head. Background Technology

[0002] A five-axis milling head contains numerous conduits and cables that need to connect to the C-axis of the milling head from the machine tool. The C-axis travel of the milling head is typically 720°, and these connecting cables also rotate 720°. During machine tool design, these conduits and cables are designed to be as long as possible to ensure sufficient flexibility, but they are prone to tangling during use. While cables can generally be selected for their flexibility during production, conduits are more challenging. Conduits typically need to withstand significant pressure, so their materials are usually harder. After prolonged and repeated rotation, conduits are highly susceptible to fatigue, leading to leaks.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figure 1 as well as Figure 2 The present invention includes a fixed component 10, a rotating component 20, a connector 30, a pipe 40, and a sealing ring 50.

[0026] The fixed component 10 includes a bearing housing 11, a cooling sleeve 12, a fixing cover 13, a first connecting post 14, and a connecting sleeve 15. The bearing housing 11 is fixedly connected to the machine tool spindle box. The cooling sleeve 12 is fixed to the bearing housing 11 and located above the bearing housing 11. The fixing cover 13 is fixed to the top of the cooling sleeve 12, and the fixing cover 13 and the bearing housing 11 are located at opposite ends of the cooling sleeve 12. The bottom of the first connecting post 14 is fixed above the fixing cover 13, and the connecting sleeve 15 is fixed to the top of the first connecting post 14. Specifically, there are multiple first connecting posts 14, which are evenly distributed along the edge of the fixing cover 13. The bearing housing 11, cooling sleeve 12, fixing cover 13, first connecting post 14, and connecting sleeve 15 are all arranged along the axis of the milling head.

[0027] Please see Figure 3 The connecting sleeve 15 includes an end plate and a main body extending from the end plate. The end plate is used to mount the connector 30. The connecting sleeve 15 has a channel 150 extending from the end plate to the main body, and the connector 30 communicates with the channel 150. Specifically, since the milling head involves multiple liquid and gas controls such as A-axis clamping, broaching, tool release, A-axis cooling, and air blowing, there are multiple connectors 30, which are evenly spaced on the end plate. The number of channels 150 is the same as the number of connectors 30, and each connector 30 communicates with one channel 150.

[0028] The rotating component 20 includes a housing 21, a drive shaft 22, a rotating cover 23, a second connecting post 24, and a rotating shaft 25. The housing 21 is located at the bottom of the bearing housing 11 and is rotatably connected to it. The drive shaft 22 is sleeved on the cooling sleeve 12, and both ends of the drive shaft 22 are connected to the housing 21 and the rotating cover 23, respectively. The bottom end of the second connecting post 24 is fixedly connected to the rotating cover 23, and the top end of the second connecting post 24 is fixedly connected to the rotating shaft 25. Since the drive shaft 22 extends from the fixed cover 13 and the rotating shaft 25 extends into the connecting sleeve 15, with the bottom end of the rotating shaft 25 located outside the connecting sleeve 15, the length of the second connecting post 24 is less than the length of the first connecting post 14. The pipe 40 is located between the rotating shaft 25 and the rotating cover 23.

[0029] Please see Figure 4 as well as Figure 5 The outer wall of the rotating shaft 25 is provided with multiple annular grooves 250 along the axial direction. These grooves are parallel to each other and spaced apart, extending from the top to the bottom of the rotating shaft 25. The annular grooves 250 are evenly spaced, each being circular, and located on the outer wall of the rotating shaft 25. The rotating shaft 25 also has multiple flow channels 251, each communicating with an annular groove 250. These flow channels 251 communicate with annular grooves 250 at different heights. The flow channels 251 extend along the axial direction (vertical direction), and their bottoms connect to a pipe 40. The pipe 40 extends into the drive shaft 22, providing air and fluid to the milling head, enabling multiple functions such as A-axis clamping, tool pulling, tool releasing, A-axis cooling, and air blowing. The outer wall of the rotating shaft 25 is also provided with multiple mounting grooves 252, with at least one mounting groove 252 between two annular grooves 250. The mounting groove 252 is used to install the sealing ring 50 to achieve a seal between adjacent annular grooves 250. Specifically, the sealing ring 50 is a Glyd ring. The function of the Glyd ring is to provide a seal, which is suitable for seals with rotational movement, ensuring that water, oil, and gas in the annular groove 250 will not leak or cross-contaminate.

[0030] When using the anti-winding milling head, the fixed component 10 is fixed to the machine tool spindle box via the bearing seat 11. The cooling sleeve 12, fixed cover 13, first connecting post 14, and connecting sleeve 15 are fixed with the bearing seat 11 and do not rotate. The housing 21, drive shaft 22, rotating cover 23, second connecting post 24, and rotating shaft 25 rotate together. At this time, oil and gas flow through the external pipe to the connector 30, and from the connector 30 to the channel 150 of the connecting sleeve 15. Since the channel 150 is connected to the annular groove 250, oil or gas flows through the annular groove 250 to the flow channel 251 and enters the pipe 40, and is delivered to the inside of the anti-winding milling head. When the anti-winding milling head is working, the rotating part 20 rotates relative to the fixed part 10. The external pipeline of the machine tool is connected to the connector 30. The pipeline does not rotate during operation. The internal pipe 40 of the milling head rotates together with the rotating shaft 25 and the rotating cover 23. There is no relative rotation, so the pipe 40 will not twist. This avoids fatigue fracture and leakage caused by movement and twisting of the pipe 40, and damage and leakage caused by friction.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
