Description

Technical Field

[0001] The utility model relates to the technical field of drilling tools, and particularly relates to a wear-resistant and high-strength drilling tool. Background Art

[0002] Drilling is a basic method of hole machining. Drilling is often carried out on drilling machines and lathes, and can also be carried out on boring machines or milling machines. Common drilling machines include bench drilling machines, vertical drilling machines and radial drilling machines.

[0003] Existing drilling tools are usually installed on the tool holder. By means of the cooperation of the coolant inlet, coolant outlet and coolant channel on the drilling tool body, the drilling tool is cooled during the drilling process. However, the internally arranged coolant channel reduces the strength of the drilling tool, resulting in a decrease in the overall hardness and affecting its service life. At the same time, the coolant outlet is easily blocked when contacting the chips at the cutting part, affecting the cooling effect. Moreover, when installing the drilling tool on the machine, only bolts are usually used for fastening, resulting in poor installation stability. After retrieval, it is found that the technical solution provided by the utility model with the application number 202122436358.7 also has the above problems. Summary of the Utility Model

[0004] According to the described wear-resistant and high-strength drilling tool, the purpose of the present utility model is to solve at least one of the technical problems existing in the prior art, and provide a wear-resistant and high-strength drilling tool. Through the cooperation of the mounting block, slider, clamping block, bolt and the tool holder, the drilling tool body is more stable after installation. When the bolt loosens and slips off, the drilling tool body still has a limiting device, avoiding direct falling off and affecting the use, and preventing the drilling tool body from being knocked when it falls off. The liquid outlet pipe is matched with the spherical turntable, which can adjust the angle of the liquid outlet pipe, has a better cooling effect when cooling the drilling tool body, and can avoid the liquid outlet pipe from contacting the chips and causing blockage.

[0005] To achieve the above purpose, the present utility model also provides a tool holder with the above structure. An installation groove is arranged on the side surface of the tool holder, and a sliding groove is arranged on the side surface of the tool holder.

Under the action of a spring and a guide post, the clamping block restricts the position of the installed drilling tool body, helping the bolt to make the installation of the drilling tool body more firm and preventing the drilling tool body from directly falling off due to the loosening of the bolt. A spring is fixedly connected to the side surface of the clamping block, and a guide post is fixedly connected to the side surface of the clamping block. One end of the guide post away from the clamping block is fixedly connected to a pull plate. A cutting fluid barrel is fixedly connected to the side surface of the tool handle. A water pump is arranged inside the cutting fluid barrel. The output end of the water pump is fixedly connected to a liquid outlet pipe.
