Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and particularly relates to a tool bar device of a numerical control machine tool. Background Technique

[0002] The structural forms of the tool holders of numerical control machine tools are divided into two types: integral type and modular type. The working part of the integral type tool holder for clamping the tool is integrated with the shank part for installation and positioning on the machine tool. This type of tool holder has poor adaptability to the transformation of machine tools and parts. To adapt to the transformation of parts and machine tools, users must reserve various specifications of tool holders, so the utilization rate of tool holders is relatively low. The modular tool system is a relatively advanced tool system. The commonly used tool holders in numerical control machining are mainly divided into: drill tool holders, boring tool holders, milling cutter holders, thread tool holders, and straight shank tool holders.

[0003] When the existing boring tool holders are in use, a tool bar matching the machining distance is required. Otherwise, the length of the tool bar is insufficient to reach the required machining depth. Most of the existing boring tool holders are not adjustable in length. When in use, it is necessary to select a tool holder according to the machining distance, which is not only more cumbersome but also increases the workload of the staff.

[0004] At the same time, most of the existing tool holders are designed with detachable tool heads. The tool head is fixed by an inner hexagonal bolt. During the machining process, the position of the bolt is close to the part, and the chips during machining are easily stuck in the inner hexagonal groove of the bolt, thus affecting the staff's use of the inner hexagonal wrench to disassemble the bolt and causing inconvenience in replacing the tool head. Content of the Utility Model

A protective shell is slidably connected to the inner wall of the connection groove. A limiting groove is opened in the inner cavity of the connection groove. A limiting block is fixedly connected to the surface of the protective shell. A magnet is fixedly connected to the top of the inner cavity of the limiting groove.

[0009] Preferably, the mounting frame has the same shape as the fixing frame, and the surface of the mounting frame is slidably connected to the surface of the fixing frame.

[0010] Preferably, the diameter of the inner cavity of the connecting disc is the same as the diameter of the fixing shell, and the fixing shell is used in cooperation with the connecting disc.

[0011] Preferably, the inner cavity of the fixing shell is designed as a regular hexagon, and the surface of the fixing shell is slidably connected to the inner walls of both the mounting frame and the fixing frame.

[0023] Please refer to Figures 1-5As shown, a tool rod device of a numerically controlled machine tool comprises a tool head 1, a blade 2 is installed inside the tool head 1, and the blade 2 is installed inside the tool head 1 by bolts, so that the blade 2 can cut, one side of the tool head 1 is fixedly connected to a mounting frame 3, one side of the tool head 1 is fixedly connected to a bearing seat 4, the other side of the bearing seat 4 is fixedly connected to a threaded rod 5, the surface of the threaded rod 5 is threadedly connected to a sleeve 7, and the surface of the sleeve 7 is fixedly connected to a fixing frame 8, and the length of the device can be changed under the cooperation of the fixing frame 8 and the mounting frame 3, so that the applicability of the device can be effectively improved, the mounting frame 3 is the same shape as the fixing frame 8, and the surface of the mounting frame 3 is slidably connected to the surface of the fixing frame 8, under this action, the fixing frame 8 can be mutually connected with the mounting frame 3 The mounting frame 3 and the fixing frame 8 are connected by a clamp, so that the mounting frame 3 and the fixing frame 8 can be spliced ​​into a cylinder, thereby improving the strength of the device and preventing the device from bending. In addition, with the cooperation of the mounting frame 3 and the fixing frame 8, the sleeve 7 can be guided when it moves, so that it will not rotate under the action of the thread on the surface of the threaded rod 5 when it moves, effectively improving the stability of the fixing frame 8 when it moves. A connecting disk 9 is fixedly connected to one side of the fixing frame 8. The diameter of the connecting disk 9 is the same as that of the fixing frame 8. Under the action of the connecting disk 9, the fixing frame 8 can be supported, so that its strength can be improved, and the fixing frame 8 can be prevented from bending easily and affecting the movement. One end of the threaded rod 5 is fixedly connected to a fixing shell 6, and the inner cavity of the fixing shell 6 is a regular hexagon. The design can facilitate the staff to use the hexagonal wrench to rotate the threaded rod 5 under this action, so that the device is more convenient to adjust. The surface of the fixed shell 6 is slidably connected to the inner walls of the mounting frame 3 and the fixing frame 8. Under this action, the inner cavity of the mounting frame 3 and the fixing frame 8 can be supported to prevent the mounting frame 3 and the fixing frame 8 from being easily bent, effectively improving the strength of the device. The diameter of the inner cavity of the connecting disk 9 is the same as the diameter of the fixed shell 6. The fixed shell 6 is used in conjunction with the connecting disk 9. Under this action, the staff's hexagonal wrench can be smoothly inserted into the interior of the fixed shell 6 to prevent the connecting disk 9 from blocking the hexagonal wrench and affecting the adjustment of the device. A connecting groove 10 is provided on one side of the cutter head 1. The inner wall of 10 is slidably connected with a protective shell 14, and the protective shell 14 is designed as a U-shaped structure. The protective shell 14 is slidably connected to the surface of the blade 2. Under this action, the protective shell 14 can block the bolts on the surface of the blade 2 to prevent debris from entering the surface of the bolt and affecting the staff's disassembly and assembly efficiency of the blade 2. The inner cavity of the connecting groove 10 is provided with a limiting groove 11, and the surface of the protective shell 14 is fixedly connected to the limiting block 13. The surface of the limiting block 13 is slidably connected to the inner wall of the limiting groove 11. Under this action, the protective shell 14 can be limited so that it will not detach from the inside of the connecting groove 10, so as to prevent the connecting groove 10 from detaching from the inside of the connecting groove 10 and affecting the protection of the bolt. The top of the inner cavity of the limiting groove 11 is fixedly connected with a magnet 12, and the material of the limiting block 13 is iron.The magnet 12 is used in cooperation with the limit block 13. Under this effect, after the protective case 14 moves, the magnet 12 and the limit block 13 can cooperate to simply limit the protective case 14, avoiding the situation that the protective case 14 moves randomly, so as to improve the protection effect of the protective case 14 on the bolt.

[0024] Working principle: First, when the length of the device needs to be adjusted, use an Allen wrench to penetrate the inside of the connecting plate 9 and then insert it into the inside of the fixed case 6. Then, rotate the Allen wrench to make the fixed case 6 rotate accordingly. Under the action of the fixed case 6, the threaded rod 5 can be driven to rotate. Then, under the action of the threads on its surface, the sleeve 7 can drive the fixed frame 8 to move, so as to change the length of the device, thereby improving the applicability of the device. Then, when the blade 2 needs to be replaced, pull the protective case 14 to drive the limit block 13 to move, so that the protective case 14 no longer blocks the blade 2 and the bolt. Then, replace the blade 2 through the bolt. After the replacement is completed, pull the protective case 14 to block the bolt.
