DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, an embodiment of the present application provides a cylinder head seat ring duct processing tool, including a first tool head 1, a second tool head 2, a tool handle 3 and a tightening component 4, wherein the first tool head 1 is used to process the duct hole, and the second tool head 2 is used to process the seat ring.

[0024] like Figure 3 As shown, the shank 3 includes a first shank portion 31 and a second shank portion 32, the diameter of the first shank portion 31 is smaller than the diameter of the second shank portion 32, the first shank portion 31 includes a first connecting portion 311 and a second connecting portion 312, the diameter of the first connecting portion 311 is smaller than the diameter of the second connecting portion 312, the first connecting portion 311 is detachably connected to the first cutter head 1, the second connecting portion 312 is connected to the second shank portion 32, the second cutter head 2 is sleeved on the second connecting portion 312 and contacts the second shank portion 32, the tightening component 4 is sleeved on the second connecting portion 312 and is threadedly connected to the second connecting portion 312, the tightening component 4 contacts one end of the second cutter head 2 away from the second shank portion 32, and the tightening component 4 is used to fix the second cutter head 2 at one end of the second shank portion 32.

[0025] Specifically, the corresponding sizes of the first cutter head 1, the second cutter head 2, the shank 3 and the tightening component 4 are set according to the specifications of the seat ring and the conduit hole of the cylinder head. The first connecting portion 311 is detachably connected to the first cutter head 1, the second cutter head 2 is sleeved on the second connecting portion 312 and contacts the second shank portion 32, and the second cutter head 2 is tightened on the second shank portion 32 by the tightening component 4. The first shank portion 31 and the second shank portion 32 are an integrally formed structure. The diameter of the first connecting portion 311 is smaller than the diameter of the second connecting portion 312, so that the first cutter head 1 is compatible with the conduit hole of the cylinder head. The diameter of the second connecting portion 312 is smaller than the diameter of the second shank portion 32, so that the second cutter head 2 is compatible with the seat ring of the cylinder head.

[0026] First, the second cutter head 2 is sleeved on the second connection part 312, and then the second cutter head 2 is fixed to one end of the second tool handle part 32 by the tightening component 4, and then the first cutter head 1 is fixedly connected to the first connection part 311. The machining tool is inserted into the cylinder head, and the first cutter head 1 and the second cutter head 2 simultaneously process the guide tube hole and the seat ring of the cylinder head.

[0027] In the above structure, by arranging the detachable first cutter head 1 and the detachable second cutter head 2 on the tool handle 3, the seat ring and the catheter hole can be processed at the same time, which not only improves the processing efficiency, but also improves the processing accuracy. The detachable first cutter head 1 and the detachable second cutter head 2 are also used. After a long period of processing and use, the first cutter head 1 and the second cutter head 2 produce different degrees of wear. The first cutter head 1 and the second cutter head 2 can be replaced separately, which reduces the configuration cost and production cycle and prolongs the service life of the tool.

[0028] like Figure 3 As shown, in one embodiment, the first tool handle portion 31 and the second tool handle portion 32 of the cylinder head seat ring conduit processing tool are an integrally formed structure. This arrangement improves the support strength of the tool handle 3.

[0029] like Figure 2 and Figure 3 As shown, in one embodiment, the first tool head 1 of the cylinder head seat ring duct processing tool includes a tool body 11 and a plurality of first blades 12 arranged along the circumference of the tool body 11, and a connecting outer cone 13 is provided at one end of the tool body 11 close to the first connecting portion 311, and the first connecting portion 311 is provided with a positioning inner cone 001 for positioning and cooperating with the connecting outer cone 13, the connecting outer cone 13 extends into the positioning inner cone 001 and is threadedly connected with the positioning inner cone 001, and the outer side of the tool body 11 is flush with the outer side of the first connecting portion 311.

[0030] Specifically, three first blades 12 are arranged along the circumference of the blade body 11, and the three first blades 12 are respectively welded to the blade body 11 or fixedly connected by bolts. The connecting outer cone 13 and the blade body 11 are an integrally formed structure, and the connecting outer cone 13 extends into the positioning inner cone 001 of the first connecting portion 311 and is fixedly connected to the positioning inner cone 001 by threads.

[0031] This arrangement facilitates fixing the blade body 11 on the first connecting portion 311 , thereby improving assembly and disassembly efficiency.

[0032] like Figure 2As shown, in one embodiment, the tool body 11 of the cylinder head seat ring conduit processing tool is symmetrically provided with tightening grooves 14 for tightening the tool body 11 with a wrench. The tightening grooves 14 are clamped by a wrench in the prior art to firmly fix the tool body 11 on the first connecting portion 311 of the tool handle 3. This arrangement ensures that the first tool head 1 will not be loosened during use, thereby ensuring the processing accuracy and processing efficiency.

[0033] like Figure 1 As shown, in one embodiment, the second cutter head 2 of the cylinder head seat ring duct processing tool includes a cutter ring 21 and at least two second blades 22 arranged along the circumference of the cutter ring 21, and the cutter ring 21 and the second shank portion 32 are stopped by a stop pin. Six or eight second blades 22 can be arranged along the circumference of the cutter ring 21, and the second blades 22 and the cutter ring 21 are welded together or fixed together by bolts. When the cutter ring 21 is sleeved on the second connecting portion 312, the cutter ring 21 and the second shank portion 32 are positioned by the stop pin, and the stop effect is achieved. The provision of multiple second blades 22 greatly improves the processing efficiency of the seat ring. The provision of the stop pin facilitates the positioning and stopping of the cutter ring 21 and the second shank portion 32.

[0034] like Figure 1 As shown, in one embodiment, the number of the second blades 22 of the cylinder head seat ring conduit processing tool is 8. This arrangement greatly improves the processing efficiency of the second cutter head 2 on the seat ring.

[0035] like Figure 1 As shown, in one embodiment, the tightening component 4 of the cylinder head seat ring conduit processing tool is a nut, which is threadedly connected to the second connecting portion 312, and the nut is used to tighten the second cutter head 2 at one end of the second tool handle portion 32. The nut is sleeved on the second connecting portion 312, and the nut is tightened and fixed to the second connecting portion 312 and one end of the second tool handle portion 32 by a wrench in the prior art. This setting can not only prevent the second cutter head 2 from loosening during the processing, but also ensure the processing accuracy of the second cutter head 2.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
