Description

Technical Field

[0001] This utility model relates to the field of machine tool tool holder technology, specifically a tool holder for machine tools. Background Technology

[0002] The tool post is a very important component of a machine tool, its main function being to mount the cutting tools used to cut the workpiece. The number of tools that can be mounted on the tool post of a machine tool is generally 4, 6, 8, 10, 12, 20, or 24, and some CNC lathes can mount even more tools. The structural forms of the tool post can be divided into rotary type and straight-line type.

[0003] For rotary tool holders, each tool is fixed with an independent bolt. When it is necessary to install or remove the tools on the tool holder, the bolts of each tool need to be tightened or loosened individually, and the tools need to be installed or removed one by one. The operation is very cumbersome and takes a lot of time, which reduces the efficiency of tool installation and removal on the entire tool holder.

[0004] Therefore, how to design a tool holder for machine tools has become a problem that we need to solve. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a tool holder for machine tools, solving the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a tool holder for a machine tool, comprising a tool holder, a cutting tool, and a connecting mechanism. Four rotating mounting seats are fixedly connected around the tool holder. One end of each mounting seat is provided with a slot adapted to the cutting tool. A connecting groove is provided on one side of the cutting tool. The tool holder has a cavity inside, and the connecting mechanism is disposed within the cavity.

[0009] The connecting mechanism includes a connecting block slidably installed between the cavity and each slot, a turntable rotatably installed inside the cavity, a connecting rod hinged between the edge of the turntable and each connecting block, and an operating disc coaxially connected to the top of the turntable.

[0010] Preferably, the inner wall of the slot is provided with a guide groove, and the outer wall of the tool is provided with a guide block that matches the guide groove.

[0011] Preferably, the top of the operating panel has an internal hexagonal groove.

[0013] Preferably, the top of the tool holder has a circular groove, and the operating disc is embedded in the circular groove.

[0014] Preferably, the top of the operating panel is hinged with a round cover for covering the circular groove.

[0015] (III) Beneficial Effects

[0016] This utility model provides a tool holder for machine tools, which has the following advantages:

[0017] This invention, through the design of a connecting mechanism, allows each tool to be inserted into its corresponding mounting slot during installation. Then, by using a suitable tool inserted into the hexagonal groove to rotate the operating disc, the disc drives the turntable to rotate, causing the turntable to slide the connecting block into the tool's connecting groove via the connecting rod. This simultaneously connects and secures all the tools. When it is necessary to disassemble the tools, simply rotate the operating disc in the opposite direction to release all the tools from their fixation, allowing for quick removal of all tools and improving the efficiency of tool installation and disassembly on the entire tool holder.

[0018] This invention, through the setting of positioning holes and pins, allows the pin to be inserted into the positioning holes after the operation of the control panel is completed. The lower end of the pin passes through the positioning holes and inserts into the positioning groove in the tool holder, thereby positioning the control panel and preventing it from rotating.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0026] like Figure 1-3As shown, this utility model provides a technical solution: a tool holder for a machine tool, including a tool holder 1, a cutting tool 2, and a connecting mechanism 3. Four rotating mounting seats 11 are fixedly connected around the tool holder 1. One end of each mounting seat 11 has a slot 12 adapted to the cutting tool 2. A connecting groove 21 is provided on one side of the cutting tool 2. The tool holder 1 has an internal cavity, and the connecting mechanism 3 is disposed within the cavity. The connecting mechanism 3 includes a connecting block 31 slidably mounted between the cavity and each slot 12. A turntable 32 is rotatably mounted within the cavity. A connecting rod 33 is hinged between the edge of the turntable 32 and each connecting block 31. An operating disc 34 is coaxially connected to the top of the turntable 32. The top of the operating disc 34... The tool holder has an internal hexagonal recess 35. With the connection mechanism 3, when installing the tool 2, each tool 2 can be inserted into the corresponding slot 12 of the mounting base 11. Then, by inserting the corresponding tool into the internal hexagonal recess 35, the operating plate 34 is rotated. The operating plate 34 drives the turntable 32 to rotate, so that the turntable 32 drives the connecting block 31 to slide into the connecting groove 21 of the tool 2 through the connecting rod 33. This allows all the tools 2 to be connected and fixed at the same time. When it is necessary to remove the tool 2, simply rotate the operating plate 34 in the opposite direction to release the fixation of all the tools 2. This allows all the tools 2 to be quickly removed, improving the efficiency of tool installation and removal on the entire tool holder.

[0027] The inner wall of the slot 12 is provided with a guide groove 13, and the outer wall of the tool 2 is provided with a guide block 22 that matches the guide groove 13. The guide groove 13 and the guide block 22 can guide and limit the tool 2, which can further improve the stability of the tool 2 after installation.

[0028] The operation panel 34 has a positioning hole 36 on one side and a pin 37 on the top of the positioning hole 36. After the operation of the operation panel 34 is completed, the pin 37 can be inserted into the positioning hole 36. The lower end of the pin 37 passes through the positioning hole 36 and inserts into the positioning groove in the tool holder 1, thereby positioning the operation panel 34 and preventing the operation panel 34 from rotating.

[0029] The tool holder 1 has a circular groove 14 on its top, and the operating plate 34 is embedded in the circular groove 14. The top of the operating plate 34 is hinged with a circular cover 15 for covering the circular groove 14. The circular groove 14 and the circular cover 15 can cover and protect the operating plate 34, preventing dust or debris in the working environment from falling into the gaps of the operating plate 34 and affecting its rotation.

[0030] The working process of this utility model is as follows: When installing the cutting tools 2, each cutting tool 2 can be inserted into the slot 12 of the corresponding mounting base 11. Then, simply use the corresponding tool to insert into the hexagonal groove 35 to rotate the operating plate 34. The operating plate 34 drives the turntable 32 to rotate, so that the turntable 32 drives the connecting block 31 to slide into the connecting groove 21 of the cutting tool 2 through the connecting rod 33. This allows all the cutting tools 2 to be connected and fixed at the same time. After operating the operating plate 34, the pin 37 can be inserted into the positioning hole 36. The lower end of the pin 37 passes through the positioning hole 36 and inserts into the positioning groove in the tool holder 1, thereby positioning the operating plate 34 and preventing the operating plate 34 from rotating. When it is necessary to disassemble the cutting tools 2, simply rotate the operating plate 34 in the opposite direction to release the fixation of all the cutting tools 2, and then all the cutting tools 2 can be quickly removed, improving the installation and disassembly efficiency of the cutting tools 2 on the entire tool holder.
