Description

Technical Field

[0001] The utility model belongs to the technical field of turning tools, and in particular relates to a large-diameter inner groove processing tool. Background Art

[0002] When machining large-diameter deep-cavity grooves on a lathe, it is necessary to ensure that the extended length of the turning tool meets the requirements. The current conventional setting generally uses a longer tool bar to install the turning tool to meet the required processing requirements. However, this structural design makes the turning tool less stable during the grooving process, and tool vibration may occur, affecting the grooving processing efficiency. Utility Model Content

[0003] In view of the above problems existing in the prior art, the purpose of the present invention is to provide a large-diameter inner groove processing tool, which can ensure the stability of the turning tool and improve the processing efficiency while ensuring the processing length requirements.

[0004] The utility model provides the following technical solution: a large-diameter inner groove processing tool, including an extended tool rod, the extended tool rod including a mounting section and an extension section, the mounting section is fixedly connected to the tool holder on the lathe, and a blade assembly is detachably provided on the extension section, the blade assembly including a tool rod and a blade, the tool rod limiter is set on the extension section, and the blade is fixedly set on the tool rod.

[0005] Furthermore, the extended shank is a stepped cylindrical structure, and the diameter of the extended section is larger than the diameter of the mounting section.

[0006] Furthermore, a square mounting hole is provided at the front end of the extension section, and the knife rod is tightly fitted through the square mounting hole and fixed by a fastener.

[0007] Furthermore, the front end of the knife rod is located outside the extension section, and the blade is fixed to the end of the front end of the knife rod.

[0008] Furthermore, a group of threaded holes are opened on the extension section, and the fasteners are fastening screws. A group of fastening screws are screwed and installed in the corresponding threaded holes, and the front ends of the fastening screws are tightly against the rod body of the knife rod.

[0009] By adopting the above technology, compared with the existing technology, the beneficial effects of the present invention are as follows:

[0010] In the present invention, the stepped extension of the tool rod can, on the one hand, increase the length of the tool rod to ensure the processing requirements of large-diameter internal grooving; on the other hand, the variable-diameter structural design improves the rigidity of the turning tool mounting section, and combined with the tight-fitting installation of the tool rod and the fastening installation method of the fastening screw, greatly increases the stability of the turning tool mounting structure, reduces the occurrence of tool vibration, can effectively improve processing efficiency, and provides a turning tool structure that is easy to install and disassemble.

[0013] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] Rather, the present invention encompasses any alternatives, modifications, equivalents, and solutions within the spirit and scope of the present invention as defined by the claims. Furthermore, to facilitate a better understanding of the present invention, certain specific details are detailed below in the detailed description of the present invention. Those skilled in the art will be able to fully understand the present invention without these details.

[0015] See also Figure 1-2 A large-diameter inner groove processing tool includes an extended tool rod 1 and a blade assembly 2 arranged on the extended tool rod 1.

[0016] Specifically, the extended shank 1 is stepped, and includes a mounting section 101 and an extension section 102. Both the mounting section 101 and the extension section 102 are cylindrical structures, and the diameter of the extension section 102 is larger than the diameter of the mounting section 101. In this embodiment, the diameter of the extension section 102 is 50 mm.

[0017] A threaded hole is provided in the middle of the mounting section 101 for mounting on a tool holder of a lathe.

[0018] A square mounting through hole is formed at the front end of the extension section 102 .

[0019] Specifically, the blade assembly 2 includes a knife rod 201 and a blade 202. The shape and direction of the knife rod 201 match the mounting through hole. It is tightly inserted into the mounting through hole and is set. The knife rod 201 is limited and fastened from the side by two fastening screws; one end of the knife rod 201 is located on the outside of the extension section 102, and the blade 202 is fastened to the end of the outer end of the knife rod 201 by screws.

[0020] The structure of this embodiment, on the one hand, is based on the structural design of the stepped extended tool bar 1, which can ensure the processing requirements of the groove depth while ensuring the overall structural rigidity of the extended tool bar 1; on the other hand, the tight-fitting installation of the tool bar 201 and the fastening installation method of the fastening screw ensure the installation stability of the tool bar 201, while also improving the stability of the turning tool installation structure, reducing the occurrence of tool vibration, and effectively improving the processing efficiency;
