During use, the transmission end of the tool holder 2 is fixedly assembled to the tool assembly through a connecting component. The deformable sleeve 3 is placed in the mounting hole and is restricted to move within the mounting hole after being connected to the high-strength chuck 4. Furthermore, the high-strength chuck 4 is threadedly fixed to the connecting end of the tool holder 2, and during use, the movement of the deformable sleeve 3 in the mounting hole is controlled by the threaded engagement between the high-strength chuck 4 and the connecting end of the tool holder 2. During the movement, the deformable sleeve 3 clamps or releases the tool 1. The structure is reasonable and is not prone to loosening or vibration during use. This phenomenon helps improve the processing efficiency and accuracy of water heating valves.

[0022] The sealing plug 29 is made of TC4 titanium alloy and has a micro-arc oxide film layer on its surface.

[0023] As can be seen from this embodiment, the sealing plug 29 is made of TC4 titanium alloy, which has high strength, low density and excellent corrosion resistance, and can effectively inhibit the corrosion of coolant. In addition, a micro-arc oxide film layer is provided on its surface. A dense oxide film is generated on the surface of TC4 titanium alloy by high-voltage discharge through micro-arc oxidation technology, which can greatly improve the sealing performance and prevent coolant from entering the cutter head.

Setting the water-stop ring 9 can effectively prevent coolant from seeping into the tool head during the processing and causing damage, achieving double sealing and extending service life.

[0036] Example 6:

[0037] This embodiment provides a TC4 titanium alloy sealing structure for a water heating valve combination machine tool cutter head, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] The drive end of the tool holder 2 is connected to a transmission component; The transmission components include: Transmission component 17 is connected to the transmission end of the tool holder 2; The bearing assembly includes a first bearing 18, a second bearing 19 and a third bearing 20; The first bearing 18 and the second bearing 19 are sequentially arranged at the transmission end of the tool holder 2, the third bearing 20 is arranged on the transmission component 17, and a retaining ring 21 is arranged between the second bearing 19 and the third bearing 20.

[0039] As can be seen in this embodiment, the transmission end of the tool holder 2 is connected to a transmission assembly, which includes a retaining ring, a transmission component 17, and a bearing assembly. The transmission component 17 is disposed on the transmission end of the tool holder 2 and connected to the countersunk hole. In use, the transmission component 17 cooperates with the transmission shaft, thereby driving the tool holder 2 to rotate the tool 1. Furthermore, the bearing assembly includes a first bearing 18, a second bearing 19, and a third bearing 20. The first bearing 18 and the second bearing 19 are both installed on the transmission end of the tool holder 2, and the third bearing 20 is installed on the transmission component 17. During use, the first bearing 18, the second bearing 19, and the third bearing 20 can reduce the impact on the tool holder 2. Friction between the tool 1 assembly and the tool holder 2 is reduced, thereby reducing transmission loss and improving transmission efficiency. Furthermore, a retaining ring 21 is positioned on the transmission end of the tool holder 2, between the second bearing 19 and the third bearing 20. The retaining ring 21 tightly abuts against the second bearing 19 and the third bearing 20, thereby increasing the compactness of the structure and preventing vibration of the tool holder 2 that could affect the transmission efficiency. The transmission component 17 includes a main body 22, which includes a mating end 23 and a mounting end 24. The mating end 24 is tapered and has a toothed surface.

The main body 22 drives the tool holder 2 through the toothed surface mating with the transmission shaft. The upper part has a connecting hole that passes through the mating end 23 and the mounting end 24. In use, the fastener 25 connects the connecting hole and the countersunk hole in sequence to fix the main body 22 to the transmission end of the tool holder 2. A first keyway is formed on one side of the connecting hole. A second keyway is set on the transmission end of the tool holder 2 corresponding to the position of the first keyway. In use, after the main body 22 and the transmission end of the tool holder 2 are mated, a fixing key is placed in the first keyway. The fixing key can effectively improve the transmission effect of the transmission component 17 to the tool holder 2, and at the same time, it can prevent slippage between the transmission component 17 and the tool holder 2. The transmission component 17 is mated with the transmission shaft through the tooth surface on the mating end 24. The transmission component 17 is small in size, which can reduce the size of the combined power head. At the same time, the tooth surface meshing can improve the transmission accuracy. An elastic ring 27 is provided between the connecting surfaces of the transmission component 17 and the transmission end of the tool holder 2, so that the transmission component 17 can be firmly connected to the transmission end of the tool holder 2, thus preventing loosening. The inner side of the protrusion 14 is provided with a bearing seal ring 28, which is locked between the fixing plate 10 and the tool holder 2. The bearing seal ring 28 abuts against the first bearing 18, which can prevent external dust, moisture and other impurities from entering the bearing and also prevent the lubricating oil inside the bearing from leaking.
