Technical Field

[0001] The utility model relates to the technical field of CNC lathes, in particular to a fully enclosed flat bed linear rail CNC lathe. Background Art

[0002] The fully enclosed flat bed linear rail CNC lathe is an advanced CNC machining equipment with a fully enclosed machine tool structure and a linear rail guide system. It has made comprehensive improvements and innovations in the design and function of the lathe, aiming to improve operational safety, protect the environment and improve processing efficiency. The machine tool structure of the fully enclosed flat bed linear rail CNC lathe adopts a closed design. The entire lathe is surrounded by a sealed shell, which effectively isolates the internal and external environments of the lathe. This design can prevent chips and lubricating oil from splashing out of the lathe and reduce noise and dust pollution in the working environment. At the same time, the fully enclosed structure can also provide better safety protection, prevent operators from contacting the moving parts of the machine tool, and reduce the risk of accidental injury. The linear rail guide system is a key component of the fully enclosed flat bed linear rail CNC lathe. It uses linear guide technology to make the lathe have high precision, high rigidity and high stability. The linear guide system consists of rolling elements and sliders, and through a special sliding method, it enables the worktable to process in a smooth linear motion. This design not only improves the rigidity and stability of the lathe, but also reduces vibration and noise during processing, and improves processing accuracy and surface quality. The fully enclosed flat bed linear rail CNC lathe is also equipped with an advanced CNC system that controls the movement and processing of the machine tool through programming. The CNC system can receive the processing program input by the user, and automatically control the movement of the workbench and tool according to the preset processing path and parameters to achieve efficient automated processing. The operator can operate through the human-machine interface, monitor the processing process, adjust the processing parameters, and understand the processing status and data in real time, thereby improving work efficiency and processing quality. The fully enclosed flat bed linear rail CNC lathe is widely used in machinery manufacturing, automotive parts, aerospace and other fields. It is capable of processing workpieces of various materials, such as metal, plastic, composite materials, etc. Through the selection of different tools and the adjustment of processing parameters, a variety of processing methods can be achieved, such as turning, milling, drilling, etc. At the same time, the fully enclosed flat bed linear rail CNC lathe is also highly flexible and scalable, and can be customized and modified according to user needs to adapt to different processing tasks and workpiece sizes. In short, the fully enclosed flat bed body linear rail CNC lathe is an advanced CNC processing equipment with the characteristics of safety, environmental protection, high precision and high efficiency. It provides a good working environment and processing performance through the closed structure and body linear rail guide system. In the modern manufacturing industry, the fully enclosed flat bed body linear rail CNC lathe plays an important role, helping enterprises to improve product quality, reduce production costs and improve market competitiveness. The first paragraph is to find the historical background and development history of this product on the Internet.

[0003] However, despite the advantages of fully enclosed flat bed linear rail CNC lathe in providing safety and environmental protection performance, it also has some problems. One of them is that due to the closed nature of the machine tool, the air flow is poor, which in turn generates a large amount of machining dust floating inside the machine tool. In this case, it is difficult for the operator to clearly observe the processing status of the workpiece being processed from the outside of the machine tool, which may lead to a serious decline in processing quality and even safety hazards. And the accumulation and floating of machining dust inside the machine tool may have a negative impact on the processing process. Dust will adhere to the surface of the cutting tool and the workpiece, resulting in uneven cutting force, which in turn affects the processing quality and precision. Secondly, the presence of dust may cause increased wear of the tool and the tool contact parts, shortening their service life. In addition, a large amount of dust may also cause blockage and failure of the lubrication system and cooling system inside the machine tool, thereby affecting the normal operation of the equipment.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 , Figure 2 , Figure 3 A fully enclosed flat bed linear rail CNC lathe comprises a worktable 1, a slide 2, and a clamping device 3. Three or more slides 2 are arranged along the circumference of one end surface of the worktable 1. The clamping device 3 is slidably installed in the slide 2. A spindle head 4 is fixedly arranged on the other end surface of the worktable 1. The diameter of the spindle head 4 is smaller than the diameter of the worktable 1. An arc-shaped slot 5 is also provided on the worktable 1. The arc-shaped slot 5 runs through the front and rear end surfaces of the worktable 1. The purpose of the arc-shaped slot 5 is to better collect the dust and debris generated during the processing and guide them into the dust collecting chamber 8. And because the arc-shaped slot 5 is close to the workpiece, it can more effectively inhale and guide the generated dust and debris, thereby improving the collection efficiency of the dust collection system. Please refer to Figure 4 , Figure 5 , Figure 6 , two or more fan blades 6 are fixedly installed on the spindle head 4 along its circumferential direction. The purpose of the fan blades 6 is to generate negative pressure and create airflow to effectively inhale and collect dust and debris generated during the processing. When the spindle head 4 drives the fan blades 6 to rotate, the fan blades 6 will generate negative pressure in the direction of the spindle during movement. This negative pressure can inhale the surrounding air in front of the arc-shaped slot 5 and the generated dust and debris. The spindle head 4 is also coaxially fixed with a dust collecting shell 7, and a dust collecting chamber 8 is provided in the dust collecting shell 7. The diameter of the dust collecting chamber 8 is larger than the diameter of the fan blades 6. The arc-shaped slot 5 is connected to the dust collecting chamber 8. The left end face of the dust collecting shell 7 is fixedly connected to the workbench 1. The purpose of the dust collecting chamber 8 is to collect and store the dust and debris generated during the processing to keep the working environment clean, reduce the harm to the operator, and prevent it from being scattered in the working environment. When the dust and debris in the dust collecting chamber 8 reaches a certain amount, the dust collecting shell 7 can be cleaned or replaced to maintain the normal operation of the dust collecting system. An annular hole 9 is provided on the right end surface of the dust collecting shell 7, and a filter screen 10 is provided in the annular hole 9. The purpose of the filter screen 10 is to filter the gas in the dust collecting system, separate the dust and debris therein, and ensure that the discharged gas is cleaner. When the inhaled gas enters the dust collecting system through the dust collecting chamber 8, it carries a certain amount of dust and debris. The filter screen 10 can effectively trap the dust and debris in the dust collecting chamber 8, so that it cannot be discharged with the gas.

[0026] See also Figure 1 , Figure 2 , Figure 4 , three or more arc grooves are arranged along the circumferential direction of the workbench 1. The diameter of the fan blade 6 is smaller than the diameter of the workbench 1, and there is a gap between the fan blade 6 and the workbench 1, and there is a gap between the fan blade 6 and the dust collecting shell 7, and the exhaust direction of the fan blade 6 is toward the spindle head 4. The spindle head 4 is fixedly connected to the spindle. The workbench 1 is also provided with two or more positioning holes 11 along its circumferential direction, and the workbench 1 is also provided with a clamping hole 12 coaxial with the workbench 1. The height of the dust collecting chamber 8 is greater than the thickness of the fan blade 6.

[0027] Working principle: When the fully enclosed flat bed linear rail CNC lathe is in the process of processing, the dust collection system includes a fan blade 6 fixedly installed on the spindle head 4 and a dust collection shell 7 sleeved on the fan blade 6. An annular hole 9 is provided on the end face of the dust collection shell 7, and a filter screen 10 is installed on the hole. In this way, the dust collection chamber 8 in the dust collection shell 7 can be connected to the outside world. In addition, an arc-shaped slot hole 5 is also provided on the end face of the workbench 1, so that the other side of the dust collection chamber 8 is also connected to the outside world. When the spindle head 4 drives the fan blade 6 to rotate, a negative pressure toward the spindle direction is generated. This negative pressure causes the air in front of the arc-shaped slot hole 5 to be sucked into the dust collection chamber 8. The gas sucked into the dust collection chamber 8 will be filtered through the filter screen 10 and then circulated back to the outside world. In this way, the dust and debris in the gas will remain in the dust collection chamber 8. And because the arc-shaped slot hole 5 is set on the end face of the workbench 1 and is close to the workpiece being processed. Therefore, when the workpiece generates dust or debris, they will be immediately sucked into the arc-shaped slot hole 5 with negative pressure, so that most of the dust or debris will be sucked into the dust collecting chamber 8.
