[0002] CNC machining centers are commonly used equipment for processing mechanical parts. Their intelligent operation saves labor and offers high precision. Their main structure includes a control system, a rotary drive shaft, and a spindle head. The electric spindle on the spindle head also has an angle adjustment function. Currently, existing machining centers often use bolts to fix the rotary drive shaft and spindle head together. This method improves the strength of the machining structure, thereby ensuring service life and machining accuracy.

[0003] However, in actual use, on the one hand, different spindle heads need to be replaced according to different parts being processed. The above-mentioned structure of fixing the spindle head with bolts requires removing the bolts and taking off the spindle head first when disassembling and replacing it, and then using bolts to fix the new spindle head. The operation is complicated, inefficient, and labor-intensive. On the other hand, the electric spindle needs to be liquid-cooled during rotation, and it is also inconvenient to set up liquid cooling pipelines connected to the electric spindle in the above-mentioned equipment.

Moreover, this utility model also includes a rotary joint. By setting a liquid passage on the rotary joint, it is possible to continuously supply liquid to the rotating electric spindle for cooling and lubrication. The liquid conduit is more convenient to set, ensuring that the electric spindle can work stably for a long time.

[0006] To achieve the above objectives, this utility model provides a direct-drive angle-adjusting shaft head, comprising a main body, a quick-connect coupling, and an electric spindle. The electric spindle is disposed in a receiving cavity located in the middle of the main body. The main body includes a torque motor, the output end of which is fixedly connected to the electric spindle.

[0008] Furthermore, the outer wall of the fixed part is sealed and fitted to the inner wall of the rotating part, and an annular passage portion of the liquid passage is formed between the outer wall of the fixed part and the inner wall of the rotating part. The liquid passage also includes a straight passage portion located in the fixed part and communicating with the liquid inlet. The two ends of the annular passage portion are respectively connected to the straight passage portion and the liquid spraying passage on the electric spindle.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-3 As shown, this embodiment provides a direct-drive angle-adjusting shaft head, including a main body 1, a quick-connect coupling, and an electric spindle 2. The electric spindle 2 is disposed in a receiving cavity located in the middle of the main body 1. The main body 1 includes a torque motor 5. The output end of the torque motor 5 is fixedly connected to the electric spindle 2. The quick-connect coupling is fixed at the end of the main body 1 and is used to fixally connect the mating joint of the rotary drive shaft.

[0030] Furthermore, the electric spindle 2 has a rotating shaft inside, the end of which is used to fix the machining tool. A receiving cavity is provided in the middle of the main body 1, and the electric spindle 2 is housed within the receiving cavity. The output end of the torque motor 5 is fixedly connected to the electric spindle 2 to drive the electric spindle 2 to rotate.

[0031] This invention improves the efficiency of shaft replacement by providing a quick-connect connector at the end of the main body 1, which can be quickly connected to the mating connector on the rotary drive shaft.

[0032] Furthermore, the main body 1 also includes a rotary joint, which has a liquid passage communicating with the liquid spraying passage in the electric spindle 2. The rotating part 3 of the rotary joint is fixedly connected to the electric spindle 2. The rotating part 3 is provided with a liquid outlet communicating with the liquid passage. The fixed part 4 of the rotary joint is provided with a liquid inlet communicating with the liquid passage. The quick-connect joint is provided with an electrical socket and a liquid circuit socket. The electrical socket is communicatively connected to the electric spindle 2 through a wire 10.

[0033] Specifically, the rotating part 3 of the rotary joint is fixedly connected to the electric spindle 2 and rotates synchronously with the electric spindle 2; the fixed part 4 of the rotary joint is rotatably connected to the electric spindle 2, and the central axis of the rotatable connection is coaxial with the rotation axis of the output end of the torque motor 5, ensuring that the fixed part 4 remains stationary while the electric spindle 2 rotates. This invention can achieve angle adjustment of the machining tool in two directions.

[0034] In this embodiment, the quick-connect coupling and the docking coupling of the rotary drive shaft are male and female couplings, which can achieve quick connection. Both can use existing devices, and their specific structures will not be described in detail.

[0035] Therefore, this embodiment provides a quick-connect connector at the end of the main body 1, which can be quickly connected to the mating connector on the rotary drive shaft, improving the efficiency of shaft replacement. This embodiment also provides a rotary connector. By setting a liquid passage on the rotary connector and setting the liquid inlet of the liquid passage on the fixed part 4 and the liquid outlet on the rotating part 3, it is possible to continuously supply liquid to the rotating electric spindle 2 for cooling and lubrication. Moreover, the liquid conduit 11 is more convenient to set, and the rotation of the electric spindle 2 will not cause the liquid conduit 11 to curl or entangle, ensuring that the electric spindle 2 can work stably for a long time.

[0036] Furthermore, the outer wall of the fixed part 4 is sealed and fitted to the inner wall of the rotating part 3, and an annular passage portion 6 is formed between the outer wall of the fixed part 4 and the inner wall of the rotating part 3 in the liquid passage.

The clamp 8 is a ring structure, with one part fixed to the housing and the other part fixed to the main body 1, thereby enabling the electric spindle 2 to be clamped and fixed at a specified angle through pneumatic control.

[0040] Furthermore, it also includes an outer cover 9 fixedly fitted onto the outside of the main body 1, with the wires 10, liquid conduit 11, and gas conduit all housed inside the outer cover 9. This prevents interference between the wires 10, liquid conduit 11, and gas conduit and other equipment.

[0041] Furthermore, a hydraulic quick-connect connector 12 is provided at the hydraulic inlet, and an electrical aviation plug 13 is provided at the electrical outlet.

The mating gear 15 is used to connect the mating joint of the rotary drive shaft. Correspondingly, the mating joint is also equipped with an output gear. Through the meshing of the mating gear 15 and the output gear, torque can be transmitted, thereby achieving the purpose of the rotary drive shaft driving the main body 1 to rotate.

[0046] Furthermore, the central surface of the electric spindle 2, which is arranged along the axial direction of the rotating shaft, is coplanar with the axis of the quick-connect coupling, and the swing angle of the electric spindle 2 is 220°. Using the aforementioned central surface as a boundary, the electric spindle 2 can rotate 110° to one side of the central surface.
