Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically to a CNC lathe with automatic clamping function. Background Technology

[0002] CNC lathes are widely used automated machining equipment in the field of mechanical processing, mainly for turning various metal and non-metal materials. In traditional CNC lathes, workpiece clamping usually requires manual operation during machining, which is not only inefficient but also prone to instability or improper clamping force due to human factors, thus affecting machining accuracy and surface quality. Furthermore, the removal of waste generated during machining also typically requires manual labor, increasing labor intensity and potentially threatening operator safety. With the development of industrial automation and intelligent manufacturing, higher demands are placed on the automation and intelligence levels of CNC lathes. Therefore, developing a CNC lathe with automatic clamping function, capable of automatically clamping, machining, and removing waste, is of great significance for improving production efficiency, machining accuracy, and operational safety.

[0003] Traditional CNC lathes typically require operators to manually place the workpiece onto the fixture and manually adjust the fixture to secure it. This process is not only time-consuming but also prone to instability or improper clamping force due to human error, affecting machining accuracy and surface quality. Manual clamping necessitates frequent movement of the operator into and out of the machining area, increasing the operator's workload and safety risks. Utility Model Content To overcome the aforementioned shortcomings, embodiments of this utility model provide a CNC lathe with an automatic clamping function, solving the problem in the prior art where unstable clamping or improper clamping force due to human factors affects machining accuracy and surface quality. Manual clamping requires operators to frequently enter and exit the machining area, increasing the operator's labor intensity and safety risks.

[0004] This utility model is achieved using the following technical solution: A CNC lathe with automatic clamping function, comprising a CNC lathe body, wherein the inner wall of the CNC lathe body is provided with an internal groove, and two internal grooves are provided. Threaded rods are installed on the inner walls of the two internal grooves, and two threaded rods are provided. Moving sleeves are drivenly connected to the surfaces of the two threaded rods, and two moving sleeves are provided. Connecting blocks are fixedly connected to the ends of the two moving sleeves that are close to each other, and two connecting blocks are provided. Electric telescopic rods are fixedly connected to the ends of the two connecting blocks that are close to each other, and two electric telescopic rods are provided. Clamping plates are fixedly connected to the ends of the two electric telescopic rods that are close to each other.

[0005] Through the above technical solution, the threaded rod, through its threaded engagement with the movable sleeve, converts the rotational motion into the linear motion of the movable sleeve, achieving precise adjustment of the movable sleeve's position. This, in turn, drives the connecting block, the electric telescopic rod, and the clamping plate to move, completing the clamping and releasing actions of the workpiece. This provides power and precise position control for automatic workpiece clamping. The movable sleeve converts the rotational motion of the threaded rod into its own linear motion and, through a fixed connection with the connecting block, transmits the motion to the connecting block, realizing the movement of the clamping mechanism. This allows the clamping plate to accurately approach or move away from the workpiece, completing the clamping and releasing operations. The electric telescopic rod, through its own telescopic movement, precisely controls the position and clamping force of the clamping plate, enabling the clamping plate to flexibly adjust its clamping position according to the size and shape of the workpiece. This achieves reliable clamping of workpieces of different sizes and shapes, improving the adaptability and accuracy of clamping, and avoiding workpiece damage or decreased machining accuracy due to improper clamping force.

[0006] As a further improvement to the above solution, two clamping plates are provided, and protective cotton is fixedly connected to one end of the two clamping plates that are close to each other. Two protective cotton are provided.

[0007] Through the above technical solution, the clamping plate directly contacts the workpiece, achieving clamping and fixing of the workpiece, providing stable support and positioning for the workpiece during processing, ensuring that the workpiece will not shift or vibrate during processing, thereby guaranteeing processing accuracy and surface quality. In conjunction with protective cotton, it prevents the workpiece from being scratched or damaged by the clamping plate during clamping, protecting the workpiece's surface quality. This is especially effective for workpieces with high surface finish requirements, effectively avoiding surface defects caused by clamping.

[0008] As a further improvement to the above solution, the tool body is provided at the rear end of the two clamping plates, and a servo motor is fixedly connected to the rear end of the inner wall of the CNC lathe body. The output end of the servo motor is connected to the rear end of the rotating shaft, and the front end of the rotating shaft is fixedly connected to the rear end of the tool body.

[0009] Through the above technical solution, the servo motor provides power for the rotation of the tool body. By precisely controlling its speed and direction of rotation, accurate drive of the tool body is achieved, thereby ensuring the accuracy and stability of the machining process. This allows the workpiece to be accurately machined according to the preset machining program and parameters, improving machining efficiency and quality. The rotating shaft transmits the output power of the servo motor to the tool body, ensuring stable power transmission and accurate connection, enabling the tool body to rotate stably and reliably to achieve the machining function, while ensuring efficiency and accuracy in the power transmission process.

[0010] As a further improvement to the above solution, a control panel is fixedly connected to the front end of the CNC lathe body, and an infrared sensor is fixedly connected to the top of the CNC lathe body.

[0011] Through the above technical solution, the control panel serves as the interface for operators to interact with the CNC lathe. It facilitates operators in inputting machining programs, setting machining parameters, and controlling the start and stop of the equipment, enabling centralized control and operation of the lathe. This improves the automation level and ease of operation, allowing operators to complete machining tasks more efficiently and accurately. The infrared sensor automatically detects the presence of the workpiece. When the workpiece is placed in the machining position, it promptly transmits a signal to the control panel, triggering automatic clamping and the start of the machining program. This achieves automated operation, reduces manual intervention, improves production efficiency and machining accuracy, and minimizes operational errors caused by human factors.

[0012] As a further improvement to the above solution, the inner wall of the CNC lathe body is connected to a rotating shaft, and four rotating shafts are provided. One end of each of the four rotating shafts is fixedly connected to a connecting column, and two connecting columns are provided. A conveyor belt is connected to the surface of the two connecting columns. A scrap box is provided at the bottom end of the conveyor belt. The surface of the scrap box is slidably connected to the inner wall of the CNC lathe body, and a handle is fixedly connected to the scrap box.

[0013] Through the above technical solution, during the processing, the processed workpiece falls onto the surface of the conveyor belt, and the movement of the conveyor belt transports the workpiece to a designated position, facilitating subsequent collection and processing. At the same time, the waste generated during the processing falls into the waste bin through the gap between the conveyor belt and the inner wall of the CNC lathe body, realizing automatic waste cleaning, keeping the inside of the machine tool clean, reducing the amount of manual cleaning work, and improving the operating efficiency and service life of the equipment.

[0014] The beneficial effects of this utility model are as follows: This utility model can quickly and accurately clamp workpieces through automatic clamping function, reduce manual operation time, improve production efficiency, and the clamping plate is controlled by electric telescopic rod, which can precisely adjust the clamping position and force to ensure the workpiece processing accuracy, reduce manual intervention, reduce the operator's contact with the machine tool, and improve operation safety. This utility model has protective cotton on the clamping plate to prevent the workpiece from being scratched or damaged during the clamping process, thus protecting the surface quality of the workpiece. The control panel and infrared sensor enable automated control, allowing for unmanned operation and reducing labor intensity. Waste generated during processing falls into the waste bin through the gap between the conveyor belt and the inner wall of the CNC lathe. Processed workpieces fall onto the surface of the conveyor belt. The waste bin can be easily pulled out for cleaning, keeping the inside of the machine tool clean. Attached Figure Description

[0027] A control panel 2 is fixedly connected to the front end of the CNC lathe body 1.

When the workpiece is placed in the machining position, it promptly transmits the signal to the control panel 2, triggering the automatic start of the clamping and machining program, realizing automated operation, reducing manual intervention, improving production efficiency and machining accuracy, and reducing operational errors caused by human factors.

[0029] The inner wall of the CNC lathe body 1 is connected to a rotating shaft 14. There are four rotating shafts 14.
