[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a detachable tool for machining the inner hole of a hydraulic cylinder, comprising:

[0031] The cutter head 1 is a rotating body, and a connecting seat 2 is provided at one end of the cutter head 1;

[0032] Multiple sets of roller mechanisms 3 are installed at opposite ends of the cutter head 1. The multiple sets of roller mechanisms 3 located at the same end of the cutter head 1 are arranged in a circular array along the axis of the cutter head 1.

[0033] The cutter head 4 is connected to the other end of the cutter head 1 by multiple bolts;

[0034] At least two tool holders 5 are connected to the tool disc 4 by multiple bolts, and the tool holders 5 are bolted with blades 6;

[0035] Multiple sets of roller mechanisms 3 located at opposite ends of the cutter head 1 are staggered to ensure that the multiple sets of roller mechanisms 3 can stably support the inner wall of the hydraulic cylinder bore.

[0036] The roller mechanism 3 includes a support sleeve 31, a roller body 32, and a cover plate 33. The end of the cutter head 1 has multiple slots 7 extending to the side wall of the cutter head 1. The support sleeve 31 is inserted into the slots 7. A C-shaped groove 8 is formed within the support sleeve 31, and the roller body 32 is inserted into the C-shaped groove 8. The cover plate 33 is fixedly connected to the end of the cutter head 1 by multiple bolts, and the cover plate 33 abuts against the end of the support sleeve 31 and the end of the roller body 32. When installing the roller mechanism 3, it is only necessary to insert the support sleeve 31 into the slots 7 and insert the roller body 32 into the C-shaped groove 8. The sidewall of the roller fits into the inner wall of the C-groove 8. The length of the support sleeve 31 is the same as the depth of the slot 7, and the length of the roller body 32 is the same as the depth of the C-groove 8. Therefore, the end of the support sleeve 31, the end of the roller body 32, and the end of the cutter head 1 coincide. The cover plate 33 is fixed to the cutter head 1 with bolts. At this time, the cover plate 33 abuts against the support sleeve 31 and the roller body 32, thus completing the installation of the roller mechanism 3. When replacing roller bodies 32 of different specifications, it is only necessary to replace the support sleeve 31 of the C-groove 8 of different specifications and the corresponding roller body 32, which makes the cutter easy to disassemble and assemble, and greatly improves the versatility of the cutter.

[0037] The cross-section of the slot 7 and the cross-section of the support sleeve 31 are both T-shaped. The slot 7 has a guiding and supporting function for the support sleeve 31, ensuring that the support sleeve 31 is stably installed in the slot 7.

[0038] The cutter head 4 has multiple positioning grooves 9. The cutter holder 5 is inserted into the positioning grooves 9. The positioning grooves 9 provide guidance and support for the installation of the cutter head 4, ensuring that the cutter holder 5 is installed stably in the positioning grooves 9.

[0039] Working principle: First, during use, the connecting seat 2 is connected to the machine. The roller body 32 abuts against the inner wall of the hydraulic cylinder to provide rolling support. The machine drives the cutter head 1 to rotate at high speed, and the blade 6 performs rotary boring on the inner hole of the hydraulic cylinder. Second, the blade 6 and the cutter holder 5 can be replaced by unscrewing the bolts. Next, when installing the roller mechanism 3, simply insert the support sleeve 31 into the slot 7 and insert the roller body 32 into the C-groove 8. The side wall of the roller fits against the inner wall of the C-groove 8. The length of the support sleeve 31 is the same as the depth of the slot 7, and the length of the roller body 32 is the same as the depth of the C-groove 8. Similarly, at this time, the end of the support sleeve 31 coincides with the end of the roller body 32 and the end of the cutter head 1. The cover plate 33 is fixed to the cutter head 1 with bolts. At this time, the cover plate 33 abuts against the support sleeve 31 and the roller body 32, thus completing the installation of the roller mechanism 3. Finally, when replacing roller bodies 32 of different specifications, the roller mechanism 3 located at one end of the cutter head 1 can be directly disassembled and replaced. The roller mechanism 3 located at the other end of the cutter head 1 can be disassembled and replaced after disassembling the cutter disc 4. Specifically, it is only necessary to replace the support sleeve 31 of the C-groove 8 of different specifications and the roller body 32 of the corresponding specifications.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
