Description

Technical Field

[0001] This utility model specifically relates to a tool fixing device for CNC lathes, belonging to the technical field of tool fixing devices. Background Technology

[0002] CNC lathes are a common type of metalworking machine. They are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other operations. Different cutting tools and tool fixing devices are required when machining metal to different degrees.

[0003] In existing tool holders, multiple sets of tools need to be installed inside. The installation process requires the operator to rotate the holder to face the operator for easy operation. Since the end of the holder is connected to the machine tool's drive mechanism, when the operator uses a tool to twist the limiting mechanism inside the holder, the force applied by the tool may cause the holder itself to move. This makes it difficult to control the accuracy of the installation process, which can easily lead to loosening of the tools and potential breakage of the tools during use. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a tool fixing device for CNC lathes, so as to achieve the purpose of fixing the tool holder.

[0005] A tool fixing device for a CNC lathe includes a main body, four sets of annularly arranged limiting grooves with an inverted "L" shape on the side of the main body, and a stabilizing component. The stabilizing component is disposed at the end of the main body and includes a telescopic spring. The telescopic spring is installed on the inner wall of the main body, and a connecting ring is fixedly connected to the end of the telescopic spring. The connecting ring is fitted into the inner wall of the main body, a limiting arm is installed on the side of the connecting ring, and a pin is fixedly connected to the end of the connecting ring. A rotating shaft is rotatably connected to the inner wall of the main body, and a turntable is fixedly connected to the end of the rotating shaft.

[0006] The mounting component is fixedly connected at its bottom to the top of the turntable, and the mounting component can limit and fix multiple sets of tools.

[0007] The detection component is installed inside the mounting component and is capable of detecting the tool fastening condition.

[0008] Furthermore, adjacent sets of limiting arms are connected by an arc-shaped bracket. The limiting arms are embedded inside the limiting groove. The turntable has four sets of circular holes inside, and the diameter of the circular holes is equal to the cross-sectional diameter of the pin.

[0009] Furthermore, the mounting components include a mounting bracket, the end of which is fixedly connected to the top of the turntable. A nut is rotatably connected inside the mounting bracket, a toothed ring is provided on the side of the nut, a gear is engaged on the side of the toothed ring, a screw is fixedly connected to the back of the gear, and a clamp is fitted onto the outer edge of the screw.

[0010] Furthermore, the outer edge of the screw is provided with two sets of opposing threads, and the contact surface between the clamping plate and the screw is provided with threaded grooves.

[0011] Furthermore, two sets of clamping plates are fitted onto the outer edge of a set of screws. The inner side of the clamping plates is textured, and the tool is held in the space between two adjacent sets of clamping plates.

[0012] Furthermore, the detection component includes a motor, which is fitted inside the fixed frame. Connecting rods are fixedly connected to both sides of the motor's output shaft, and a housing is fixedly connected to the end of the connecting rods. The housing is equipped with several sets of buttons, and a sensing shaft is rotatably connected to the inner wall of the housing. Buttons are provided on the side of the sensing shaft.

[0013] Furthermore, a fixed shell is fixedly connected to the end of the outer shell, a torsion spring is installed inside the fixed shell, a transmission rod is fixedly connected to the end of the torsion spring, one end of the transmission rod passes through the end of the outer shell and is fixedly connected to the side of the sensing shaft, and a movable plate is installed at the other end of the transmission rod.

[0014] Beneficial effects:

[0015] The device utilizes its internal structure to secure the tool holder. Compared to existing technologies, this invention combines a limiting groove with a stabilizing component. The stabilizing component's internal structure slides within the limiting groove, and the overall structure of the limiting groove limits the stabilizing component, enabling the stabilizing component structures to lock in place. This ensures the fixed position of the mounting component connected to the end of the stabilizing component, allowing personnel to easily operate and install tools on the surface of the mounting component. The stable position of the mounting component during installation makes the tool installation process smoother and facilitates the installation of multiple sets of tools. Simultaneously, the device's detection component structure can check whether multiple sets of tools are securely installed before use. By utilizing the angle of the internal structure of the detection component contacting the tool surface, when the angle of the internal structure of the detection component becomes smaller due to contact with the tool, it indicates that the tool itself is loose, thus enabling rapid detection of whether the tool is loose.

[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] Please see Figure 1-6As shown, a tool fixing device for a CNC lathe includes a main body 1. Four sets of annularly arranged limiting grooves 2, each in an inverted "L" shape, are provided on the side of the main body 1. The device also includes a stabilizing component 3, which is located at the end of the main body 1. The stabilizing component 3 includes a telescopic spring 6, which is installed on the inner wall of the main body 1. A connecting ring 7 is fixedly connected to the end of the telescopic spring 6 and fits into the inner wall of the main body 1. A limiting arm 8 is installed on the side of the connecting ring 7, and a pin 9 is fixedly connected to the end of the connecting ring 7. A rotating shaft 10 is rotatably connected to the inner wall of the main body 1, and a turntable 11 is fixedly connected to the end of the rotating shaft 10. When it is necessary to install and remove the tool inside the mounting component 4... When the tool is in use, the operator manually pushes the limiting arm 8 to slide in the limiting groove 2 inside the main body 1, so that the limiting arm 8 moves from the lowest point to the highest point of the limiting groove 2. And because the tension of the telescopic spring 6 pulls the connecting ring 7, the limiting arm 8 on the side of the connecting ring 7 will be locked into the groove at the end of the limiting groove 2. At this time, the position of the connecting ring 7 and the main body 1 is fixed, and the pin 9 at the end of the connecting ring 7 will be inserted into the turntable 11. Then the turntable 11 and the mounting component 4 connected to it are fixed in position. The operator can easily operate the stable mounting component 4 and install multiple sets of tools. The operation of the mounting component 4 is convenient and the operation process is fast, which ensures that the operator can install the tools more smoothly and facilitates the operator to install multiple sets of tools.

[0025] Mounting component 4, the bottom end of which is fixedly connected to the top of turntable 11, can limit and fix multiple sets of tools;

[0026] The detection component 5 is installed inside the mounting component 4 and is capable of detecting the tool fastening condition.

[0027] As a technical optimization of this utility model, adjacent sets of limiting arms 8 are connected by an arc-shaped bracket. The arc-shaped bracket is designed to facilitate operation by personnel. By gripping, the limiting arms 8 are moved inside the limiting groove 2. The limiting arms 8 are embedded inside the limiting groove 2. The turntable 11 has four sets of round holes inside, and the diameter of the round holes is equal to the cross-sectional diameter of the pin 9. By inserting the turntable 11 and the pin 9, the pin 9 and the turntable 11 can form a whole. At the same time, the connecting ring 7 connected to the pin 9 and the limiting arms 8 are limited by the limiting groove 2 inside the main body 1, thereby stabilizing the position of the turntable 11.

[0028] As a technical optimization of this utility model, the mounting component 4 includes a fixing frame 12. The end of the fixing frame 12 is fixedly connected to the top of the turntable 11. A nut 13 is rotatably connected inside the fixing frame 12. A toothed ring 14 is provided on the side of the nut 13. A gear 15 is meshed on the side of the toothed ring 14. A screw 16 is fixedly connected to the back of the gear 15. A clamping plate 17 is fitted into the outer edge of the screw 16. A person inserts a star screwdriver into the end of the nut 13 and rotates it, causing the toothed ring 14 on the side of the nut 13 to rotate. The teeth on the side of the toothed ring 14 drive the screw 16 to rotate. At the same time, the screw 16 on the back of the screw 16 drives the two sets of clamping plates 17 to move towards each other. The screw handle is clamped by the threads on the sides of the two sets of clamping plates 17, thereby achieving the function of fixing the tool.

[0029] As a technical optimization of this utility model, the outer edge of the screw 16 is provided with two sets of opposing threads, and the contact surface between the clamping plate 17 and the screw 16 is provided with threaded grooves. During the rotation of the opposing threads on the surface of the screw 16 inside the clamping plate 17, it can ensure that the two sets of clamping plates 17 can move in opposite directions.

[0030] As a technical optimization of this utility model, two sets of clamping plates 17 are fitted into the outer edge of a set of screws 16. The inner side of the clamping plates 17 is provided with texture. The gap between two adjacent sets of clamping plates 17 holds the cutting tool. The texture of the clamping plates 17 can increase the friction during the clamping of the cutting tool handle, making the connection process more stable.

[0031] As a technical optimization of this utility model, the detection component 5 includes a motor 18, which is fitted inside the fixing frame 12. Connecting rods 19 are fixedly connected to both sides of the output shaft of the motor 18, and a housing 20 is fixedly connected to the end of the connecting rods 19. The housing 20 is provided with several sets of buttons 21, and a sensing shaft 22 is rotatably connected to the inner wall of the housing 20. A button 23 is provided on the side of the sensing shaft 22. After all the tools are installed, to ensure the tools are securely installed, the motor 18 is turned on. Subsequently, the output shaft of the motor 18 drives the transmission rod 26 at the end of the connecting rod 19 to perform a circular motion. The movable plate 27 deflects when it contacts the tool holder. Since the tool holders are of equal size, the deflection angle of the movable plate 27 is fixed when it passes the tool holder. If the tool is loose, the angle deflection of the movable plate 27 will be smaller when it slides over the tool holder. The button 23 on the side of the sensing shaft 22 will be pressed by the button 21 in different positions, resulting in inconsistent deflection angles of the receiving transmission rod 26. This allows it to be determined that the deflection angle of the movable plate 27 is deviated, indicating that the tool is loose or not installed correctly. This enables personnel to quickly check the installation and stability of the tool.

[0032] As a technical optimization of this utility model, a fixed shell 25 is fixedly connected to the end of the outer shell 20. A torsion spring 24 is installed inside the fixed shell 25. A transmission rod 26 is fixedly connected to the end of the torsion spring 24. One end of the transmission rod 26 passes through the end of the outer shell 20 and is fixedly connected to the side of the sensing shaft 22. A movable plate 27 is installed at the other end of the transmission rod 26. The torque of the torsion spring 24 can keep the transmission rod 26 and the movable plate 27 connected to the end of the torsion spring 24 in a fixed position. Deflection can only occur when it contacts the tool holder. When the deflection angle decreases due to contact with the tool, it means that the tool itself has become loose. This can quickly detect whether the tool is loose.
