DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model.

[0024] In the description of the utility model, it is understood that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "setting" should be understood broadly, for example, can be fixedly connected, set, or can be detachably connected, set, or integrally connected, set. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] The electric main shaft center water outlet mechanism, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , including the shell 1, one end of the shell 1 is fixedly connected with the end cover 2, and the middle section of the end cover 2 is fixedly connected with the key nut 3, the other end of the shell 1 is fixedly connected with the installation shaft 5, and the circumferential side of the shell 1 close to the installation shaft 5 is fixedly connected with the side seat 4, and the end port of the shell 1 is provided with the anti-seepage mechanism;

[0026] The seepage prevention mechanism includes an internal cavity 17 of the cylinder seat, a cylinder seat 18, an external cavity 19 of the cylinder seat, an exhaust passage 20, and an intake passage 21.

[0027] like Figure 3 As shown, the circumferential side of the mounting shaft 5 is provided with sensor mounting ports 14 that are evenly distributed, and the outer wall of one side of the side seat 4 is provided with a power outlet 6 and a temperature control outlet 16.

[0028] A return air port 8 is provided on one side of the end face of the housing 1, and a central water outlet 9 is provided on the side of the housing 1 near the return air port 8. A cooling water inlet 10 is provided on one side of the end face of the housing 1.

[0029] An air seal 11 is provided on the outer wall of the housing 1 near the cooling water inlet 10, and an encoder outlet 12 is provided on the circumference of the housing 1 near the mounting shaft 5.

[0030] The housing 1 has an oil cylinder inlet 13 on one side of its circumference, an annular spray water inlet 7 on the end face of the housing 1, and a cooling water outlet 15 on the end face of the housing 1 near the sensor mounting port 14.

[0031] To prevent water overflow from the rotary joint from seeping into the spindle and damaging spindle components, such as... Figure 4 and Figure 5 As shown, the cylinder seat 18 is fixedly connected to the side of the housing 1 near the mounting shaft 5, and the inner cavity 17 of the cylinder seat is located on one side of the cylinder seat 18, the outer cavity 19 of the cylinder seat is located on the side of the housing 1 near the inner cavity 17 of the cylinder seat, the exhaust passage 20 is located on the top side of the outer cavity 19 of the cylinder seat, and the intake passage 21 is located on one side of the inner cavity 17 of the cylinder seat. The bottom of the intake passage 21 and the exhaust passage 20 are connected by an L-shaped passage.

[0032] The spindle's intermediate water-cooling structure employs a concealed, split-type rotary joint, resulting in low cost and a short structure. The leakage issue during startup is mitigated by an airtight labyrinth structure and a leakage venting mechanism. The internal air pressure of the cylinder seat is higher than the external air pressure, causing airflow to follow the direction of the large gap. The air flows from the high-pressure area to the low-pressure area, forming a uniform air curtain from the inlet channel 21 to the outlet channel 20, preventing liquid from flowing back into the interior. The liquid is blown out from the larger gap. When water is passed through the middle, it flows out from the gap into the external cavity 19 of the cylinder seat and can then flow out with the gas through the outlet channel 20. This avoids the common problem in existing electric spindles where water overflows from the rotary joint and seeps into the spindle, damaging the spindle and related components, leading to rust, corrosion, or bearing damage. This ensures the safe operation of the electric spindle.

[0033] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
