Description

Technical Field

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

[0002] In the field of machining, CNC lathes are widely used as a high-precision and high-efficiency automated machining equipment. As an important component of CNC lathes, the performance of the tool holder directly affects the machining accuracy, efficiency and machining cost.

[0003] However, existing CNC lathe tool holders still have some problems in use:

[0004] First, existing tool holders generally use bolted connections to install tools. This method is prone to bolt loosening, which can lead to unstable tool installation and affect the normal use of the tools.

[0005] Secondly, existing tool holders generally use traditional motor and gear transmission to drive the turret tool holder body. However, during tool changing, multiple transmission stages are required to achieve tool holder indexing, which is a relatively slow process and reduces tool changing speed. Utility Model Content

[0006] In order to solve the problems of unstable tool mounting and slow tool changing speed in existing tool holder structures, the purpose of this utility model is to provide a tool holder for CNC lathes.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a tool holder for a CNC lathe, comprising a base, a transmission assembly on the upper surface of the base, a turret tool holder body on one side of the transmission assembly, a slot array on one side of the turret tool holder body, and a tool sleeve movably engaged in the slot, the outer surface of the turret tool holder body being provided with a locking assembly for use with the tool sleeve, the locking assembly comprising a cylinder, the cylinder being fixedly installed on one side of the turret tool holder body, the output end of the cylinder being fixedly connected to a movable frame, and the lower surface of the movable frame being symmetrically fixedly connected to movable rods, one end of each of the two movable rods penetrating the turret tool holder body and being jointly fixedly connected to a locking ring for use with the tool sleeve.

[0008] Preferably, the transmission assembly includes a torque motor, which is fixedly mounted on the upper surface of the base. The output end of the torque motor passes through the base and is fixedly connected to the middle of one side of the turret tool holder body. A support plate is fixedly connected to one side of the base, and a support sleeve for use with the turret tool holder body is fixedly connected to the upper surface of the support plate. The outer surface of the turret tool holder body is in rotatable contact with the inner cavity of the support sleeve.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This application uses a locking mechanism to facilitate the clamping of the tool sleeve by locking the locking ring, effectively replacing the traditional bolt installation method. This can prevent the tool from being installed unstablely on the tool holder and ensure the normal use of the tool.

[0011] 2. This application utilizes a transmission assembly and a torque motor to directly drive the indexing of the turret tool holder, reducing transmission links, improving transmission efficiency and response speed, and effectively increasing the tool changing speed of the tool holder structure.

[0018] 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.

[0019] Example: Figure 1-4As shown, this utility model provides a tool holder for a CNC lathe, including a base 1. Mounting plates 5 are symmetrically fixedly connected to both sides of the base 1, facilitating the installation of the tool holder on the CNC lathe. A transmission assembly 3 is provided on the upper surface of the base 1. The transmission assembly 3 reduces transmission links, improves transmission efficiency and response speed, and effectively improves the tool changing speed of the tool holder structure. A turret tool holder body 4 is provided on one side of the transmission assembly 3. A circular array of slots 7 is provided on one side of the turret tool holder body 4, and tool sleeves 6 are movably engaged within the slots 7. A tool head body is fixedly installed on one side of the tool sleeve 6. The circular array of slots 7 allows for the reasonable arrangement of multiple tool sleeves 6, enabling the turret tool holder body 4 to accommodate more tools.

[0020] The slot 7 is a magnetic groove, and the outer surface of the tool sleeve 6 is coated with a magnetic coating. Through magnetic attraction, the tool sleeve 6 can be initially fixed and positioned when it is inserted into the slot 7, which enhances the stability and accuracy of tool installation. The outer surface of the turret tool holder body 4 is provided with a locking component 2 that works with the tool sleeve 6. The locking component 2 can fix the tool sleeve 6, prevent the tool from loosening or shifting during processing, ensure the stability of tool processing, and guarantee the normal use of the tool.

[0021] The locking assembly 2 includes a cylinder 21, which is fixedly mounted on one side of the turret tool holder body 4. A mounting bracket 23 for use with the cylinder 21 is fixedly connected to one side of the turret tool holder body 4. The cylinder 21 is fixedly mounted on the upper surface of the mounting bracket 23, which provides a stable mounting position for the cylinder 21, allowing it to be securely mounted on the turret tool holder body 4. A movable frame 22 is fixedly connected to the output end of the cylinder 21, and the cylinder 21 drives the movable frame 22 to move. The lower surface of the moving frame 22 is symmetrically fixedly connected with moving rods 24. One end of each of the two moving rods 24 passes through the turret tool holder body 4 and is fixedly connected to a locking ring 25 that works with the tool sleeve 6. The moving frame 22 drives the locking ring 25 to move through the moving rods 24. A positioning groove 27 that works with the locking ring 25 is opened on one side of the tool sleeve 6. The locking ring 25 is movably engaged with the positioning groove 27. The positioning groove 27 on the tool sleeve 6 works with the locking ring 25 to further enhance the positioning effect of the tool sleeve 6.

[0022] The turret tool holder body 4 has an annular groove 26 on one side for use with the locking ring 25. The locking ring 25 is movably engaged with the annular groove 26, and the annular groove 26 provides a locking position for the locking ring 25. The locking ring 25 is an anti-slip ring. The design of the anti-slip ring increases the friction between the locking ring 25 and the tool sleeve 6, improves the locking effect, and prevents the tool sleeve 6 from loosening during the machining process.

[0023] The transmission assembly 3 includes a torque motor 33, which provides power for the indexing of the turret tool holder body 4. Its direct drive method reduces transmission links and improves transmission efficiency and response speed. The torque motor 33 is fixedly installed on the upper surface of the base 1. A vibration damping frame 34 for use with the torque motor 33 is fixedly connected parallel to the upper surface of the base 1. The torque motor 33 is located inside the vibration damping frame 34. The vibration damping frame 34 can reduce the vibration of the torque motor 33 during operation and ensure the stability of motor operation.

[0024] The output end of the torque motor 33 passes through the base 1 and is fixedly connected to the middle of one side of the turret tool holder body 4. The output end of the torque motor 33 is directly connected to the turret tool holder body 4, which can directly transmit the power of the torque motor 33 to the turret tool holder body 4, reducing energy loss in the power transmission process and enabling the turret tool holder body 4 to quickly rotate. A support plate 32 is fixedly connected to one side of the base 1. A support sleeve 31 for use with the turret tool holder body 4 is fixedly connected to the upper surface of the support plate 32. The outer surface of the turret tool holder body 4 is in rotatable contact with the inner cavity of the support sleeve 31. The support sleeve 31 provides additional support for the turret tool holder body 4, enhances the stability of the turret tool holder body 4 during rotation, and ensures the accuracy of tool switching.

[0025] Working principle: First, the entire CNC lathe tool holder is installed on the CNC lathe by using the mounting plate 5 and the mounting components. The slot 7 is used as a magnetic suction slot and the magnetic suction coating is applied to the outer surface of the tool sleeve 6. The tool sleeve 6 is initially movably snapped into the slot 7, completing the initial positioning and installation of the tool. The tool head body is fixedly installed on the tool sleeve 6.

[0026] Then, by locking assembly 2, cylinder 21 on the upper surface of mounting bracket 23 is activated. The output end of cylinder 21 pushes moving bracket 22 to move. Moving bracket 22 drives moving rod 24 to move. Moving rod 24 drives locking ring 25 to move and tightly lock it in annular groove 26. At the same time, locking ring 25 will also be tightly locked in positioning groove 27 opened on one side of tool sleeve 6, which can effectively prevent tool sleeve 6 from loosening and ensure the stability of tool during processing.

[0027] When a tool change is required, the torque motor 33 is started through the transmission component 3. The torque motor 33 stably transmits power directly to the turret tool holder body 4, enabling the turret tool holder body 4 to quickly rotate. The support sleeve 31 provides stable support for the turret tool holder body 4, ensuring the stability of the turret tool holder body 4 during rotation, effectively reducing transmission links, and facilitating rapid turning and tool changing operations.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
