Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cemented carbide cutting tools and relates to a cemented carbide cutting tool which is easy to switch. Background Art
[0002] Cemented carbide is an alloy material made from hard compounds of refractory metals and bonding metals through a powder metallurgy process. Cemented carbide is widely used as a tool material, such as carbide tools for engraving.
[0003] In the existing cemented carbide tools, the cemented carbide tool and the tool holder are fixed together. When a set of tools is needed, a corresponding number of tools need to be brought, which is inconvenient to carry and switch. It is very necessary to design a cemented carbide tool that is easy to switch. Summary of the invention
[0004] The utility model aims to solve the above problems in the prior art and proposes a cemented carbide tool which is easy to switch.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a carbide tool that is easy to switch, including a tool holder, on which a carbide tool is fixed by a clamping sleeve, characterized in that there are several tool holders, the tool holder has a receiving cavity for receiving the carbide tool, the receiving cavity also has a threaded hole, the clamping sleeve also has a threaded portion that matches the threaded hole, and it also includes a holding sleeve.
[0006] The outside of one end of the holding sleeve is provided with an anti-slip protrusion, and the end of the other end of the holding sleeve is threadedly connected with a screw that can match the threaded hole, and the screw is also provided with a ring.
[0007] The knife seat is also provided with two notches, and the holding sleeve is also provided with a limiting block matched with the notches.
[0008] The outer surface of the middle part of the knife seat also has a knurling pattern.
[0009] Compared with the prior art, the easy-to-switch carbide tool has the following advantages:
[0010] The utility model is designed to be a plurality of mutually detachable knife seats, so that one tool can carry a plurality of carbide knives at the same time, and the switching is also very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] like Figure 1-Figure 2 As shown, the present easy-to-switch cemented carbide tool comprises a tool holder 8, on which a cemented carbide tool 6 is fixed by a clamping sleeve 7, and the existing technology is used to install the cemented carbide tool 6 on the tool holder 8 by the clamping sleeve 7; the number of tool holders 8 is several, and in the present embodiment, the number of tool holders 8 is four; the tool holder 8 has a receiving cavity 8a for receiving the cemented carbide tool 6, and the receiving cavity 8a also has a threaded hole 8b, and the clamping sleeve 7 also has a threaded portion 7a matching the threaded hole 8b, and in the present embodiment, the threaded hole 8b and the threaded portion 7a on any tool holder 8 can be threadedly connected with other tool holders 8, thereby connecting the two together; it also comprises a holding sleeve 1, after connecting multiple tool holders 8 together, the holding sleeve 1 is put on, and the limiting block 3 is inserted into the notch 8c of the tool holder 8 at the rear end, and the screw 4 is tightened; in practice, the models of the cemented carbide tools 6 installed on the tool holder 8 can be the same or different.
[0016] The outside of one end of the holding sleeve 1 is provided with an anti-slip protrusion 2, and the end of the other end of the holding sleeve 1 is threadedly connected with a screw 4 that can match with the threaded hole 8b, and the screw 4 is also provided with a ring 5.
[0017] The knife seat 8 is also provided with two notches 8c, and the holding sleeve 1 is also provided with a limiting block 3 matched with the notches 8c.
[0018] The outer surface of the middle part of the knife seat 8 also has a knurling pattern.
[0019] In the utility model, a plurality of mutually detachable knife seats 8 are designed so that one tool can carry a plurality of carbide knives 6 at the same time, and the switching is also very convenient.
[0020] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0021] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
