A machine tool protection mechanism for machining body parts

Abstract

This utility model discloses a machine tool protective mechanism for machining body parts, including a mounting base frame and vertical supports fixed at the four corners of the top of the mounting base frame. The mounting base frame is installed on the outer perimeter of the machine tool machining position. A metal top frame is connected to the top of the multiple vertical supports. A protective panel is connected between the front end of the mounting base frame and the metal top frame. By adding a novel self-contained suction and filtration device to the protective top plate of the machine tool protective mechanism, an induced draft fan draws air upward from inside the machine tool protective mechanism, and the gas generated during machining enters the device. The gas is first pre-filtered through a long filter cylinder A filled with zeolite, which adsorbs some large molecular impurities and harmful gases. Then, it is deeply adsorbed through a long filter cylinder B filled with activated carbon particles, which adsorbs residual odors, small particles, and residual harmful gases. Through two-stage filtration, harmful substances and odors are significantly reduced, effectively improving the air quality in the machine tool machining area and creating a healthy working environment for operators.

Description

Technical Field

[0001] This utility model belongs to the technical field of machine tool protection, specifically relating to a machine tool protection mechanism for machining body parts. Background Technology

[0002] In the field of automotive body parts processing, the safe and efficient operation of machine tools is crucial for production quality and worker health. Traditional machine tool safety mechanisms in automotive body parts processing mostly serve a simple protective function, primarily focusing on preventing debris, coolant, and other contaminants from splashing out during processing and causing physical injury to operators and the surrounding environment. However, with the continuous development of automotive body parts processing technology and increasingly stringent requirements for the working environment, existing safety mechanisms are gradually revealing significant limitations. During the machining of automotive body parts, harmful gases are continuously generated. These harmful gases may originate from various factors, including the volatilization of the processed materials and the decomposition of cutting fluid at high temperatures.

[0003] Because traditional protective mechanisms lack effective gas handling measures, these harmful gases can only diffuse into the air. Operators inevitably inhale these harmful gases during their daily work. Long-term exposure to such an environment poses a serious threat to operators' health, such as causing respiratory and lung diseases, and may even lead to more serious occupational diseases. Furthermore, the unorganized emission of harmful gases does not comply with modern environmental protection requirements. With increasing environmental awareness, industrial waste gas emissions are subject to increasingly stringent regulations. Traditional machine tool protective mechanisms cannot effectively handle harmful gases, affecting not only the air quality inside the workshop but also potentially polluting the surrounding environment.

[0007] Preferably, a circular through hole is provided inside the center of the top of the rectangular filter cover, and the blower box is connected to the inside of the rectangular filter cover through the circular through hole. An induced draft fan is fixed inside the blower box by a frame, and the blower generates an upward airflow when it is running.

[0008] Preferably, the self-contained suction filtration device further includes a fixed insert A, a fixed insert B, a filter media tube A, an air hole, a sealing cap, and a filter media tube B. Multiple fixed inserts A are equidistantly inserted and fixed to the upper side of the front center of the rectangular filter cover, arranged equidistantly from left to right. Multiple fixed inserts B are equidistantly inserted and fixed to the lower side of the right center of the rectangular filter cover, arranged equidistantly from front to back. A filter media tube A is inserted into each of the multiple fixed inserts A, and a filter media tube B is inserted into each of the multiple fixed inserts B. The rear end of the filter media tube A and the left end of the filter media tube B are respectively attached to the inner wall of the rear end and the inner wall of the left end of the rectangular filter cover.

[0009] Preferably, both the front opening of the filter media cylinder A and the right opening of the filter media cylinder B are fitted with sealing caps.

[0014] Compared with the prior art, this utility model provides a machine tool protection mechanism for machining body parts, which has the following beneficial effects:

[0015] This invention adds a novel self-contained suction and filtration device to the protective top plate of the machine tool protective mechanism. This device continuously draws air upwards from inside the machine tool protective mechanism via an internal fan, while gases generated during the machining of body parts on the machine tool continuously pass through it. The self-contained suction and filtration device efficiently purifies the passing gas in real time. Specifically, when gas containing impurities, odors, or other harmful components enters the rectangular filter hood, it first undergoes preliminary filtration through the filter media cylinder A, which then fills the filter media cylinder A. Zeolite has a large specific surface area and adsorption capacity, which can effectively adsorb some large molecular impurities and some harmful gas components in the gas, reducing solid particles and some chemical pollutants in the gas. Then, the gas continues to rise and enters the filter media tube B. Activated carbon particles have a strong adsorption capacity, which deeply adsorbs the remaining odors, small particles and some residual harmful gases, further purifying the gas. After such two-stage filtration, the harmful substances and odors in the discharged gas are greatly reduced, effectively improving the air quality in the machine tool processing area and providing a healthier working environment for operators.

[0022] 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.

[0023] This utility model provides, for example Figure 1-5The machine tool protective mechanism for machining body parts, as shown, includes a mounting base frame 5 and vertical brackets 1 fixed at the four corners of the top of the mounting base frame 5. The mounting base frame 5 is installed around the outer perimeter of the machine tool machining position. A metal top frame 8 is connected to the top of each of the vertical brackets 1. A protective panel 2 is connected between the front end of the mounting base frame 5 and the front end of the metal top frame 8. Both ends of the protective panel 2 are fixed to the vertical brackets 1 with screws. This screw connection ensures the secure installation of the protective panel 2 and facilitates disassembly and maintenance when needed. Protective side plates 10 are connected between the left and right ends of the mounting base frame 5 and the metal top frame 8. Both the front and rear ends of the protective side plates 10 are fixed to the vertical brackets 1 with screws. The protective side plates 10 can effectively prevent splashes, coolant, and other contaminants generated during machine tool machining from spreading to the sides. A protective top plate 7 is fixed to the top of the metal top frame 8. A protective back plate is connected between the bottom frame 5 and the rear end of the metal top frame 8. The left and right ends of the protective back plate are fixed to the vertical bracket 1 by screws. A door window 3 is set inside the center of the protective panel 2. A protective door 4 is set inside the door window 3. The protective door 4 is rotatably connected to the protective panel 2 by multiple hinges. A door handle is also fixed to the front end of the protective door 4. Glass windows 11 are set inside the protective door 4 and inside the two protective side plates 10. The principle of this design is to ensure the protection of the machine tool processing area while facilitating the operator to enter and exit the machine tool processing area for operation, maintenance and workpiece replacement. The door handle fixed to the front end of the protective door 4 provides convenience for human operation, allowing the operator to easily open and close the protective door 4.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, each of the multiple glass windows 11 has a transparent glass 6 fixed inside. The transparent glass 6 is tempered glass, and the joint between the transparent glass 6 and the glass window 11 is sealed with glass glue. The principle of using tempered glass is that it has high strength and impact resistance, which can ensure that the operator can observe the machine tool processing while effectively preventing the glass from being broken by flying debris during processing and causing injury to the operator. Moreover, the sealing treatment at the joint between the transparent glass 6 and the glass window 11 further enhances the stability and sealing of the glass installation, preventing dust, coolant, etc. from entering or leaking out from the gap between the glass and the window. The mounting base frame 5, multiple vertical supports 1, and metal top frame 8 together form a cuboid frame structure. Furthermore, the cubic frame structure completely protects the outside of the machine tool processing station. The principle of this structural design is to provide a stable and robust frame that can organically connect the various protective components together to form a complete protective system. The mounting base frame 5 is installed on the outer perimeter of the machine tool processing station, serving as the basic support component of the entire protective mechanism, ensuring that the protective mechanism is placed stably around the machine tool. The vertical bracket 1 is fixed at the four corners of the top of the mounting base frame 5, which not only serves to connect the metal top frame 8, but also enhances the overall stability of the frame structure, enabling the protective mechanism to withstand certain external impacts without deformation or damage. The metal top frame 8 closes the top of the frame, further improving the integrity of the protection and preventing foreign objects from falling into the machine tool processing area from above.

[0025] like Figure 1 , Figure 4 and Figure 5As shown, a self-contained suction and filtration device 9 is installed at the center of the top of the protective top plate 7. The self-contained suction and filtration device 9 includes a rectangular fixing flange 12, a rectangular filter cover 13, a blower housing 15, and a protective net 16. A rectangular through hole is provided inside the center of the protective top plate 7. A rectangular filter cover 13 is installed on the outer side of the top of the rectangular through hole. A rectangular fixing flange 12 is installed on the outer side of the bottom of the rectangular filter cover 13. The rectangular fixing flange 12 is fixedly connected to the protective top plate 7 by multiple screws. The bottom of the rectangular filter cover 13 is open and communicates with the rectangular through hole. The blower housing 15 is fixed to the top of the rectangular filter cover 13. A protective net 16 is fixed inside the opening at the top of the blower housing 15. The rectangular fixing flange 12 is fixedly connected to the protective top plate 7 by multiple screws. This connection method ensures the stability of the entire device installation. The filter cover 13 is located above the rectangular through hole of the protective top plate 7, and its bottom opening is connected to the rectangular through hole, providing a channel for gas to enter the filter device from inside the machine tool protection mechanism. The induced draft fan box 15 is fixed to the top of the rectangular filter cover 13 and is connected to the inside of the rectangular filter cover 13 through the circular through hole at the center of the top of the rectangular filter cover 13. When the induced draft fan inside the induced draft fan box 15 runs, it generates an upward airflow. The principle is to use the power of the induced draft fan to form an upward airflow channel inside the device, so that the air inside the machine tool protection mechanism can be drawn out, thereby causing the exhaust gas generated during the processing to enter the device for treatment. The protective net 16 is fixed inside the top opening of the induced draft fan box 15. Its function is to prevent foreign objects from entering the induced draft fan box 15, avoid damage to the induced draft fan due to foreign objects entering, and ensure the stable operation of the device.

[0026] like Figure 1 , Figure 4 and Figure 5As shown, a circular through hole is provided inside the center of the top of the rectangular filter cover 13. The blower box 15 is connected to the inside of the rectangular filter cover 13 through the circular through hole. An induced draft fan is fixed inside the blower box 15 by a frame. When the blower is running, it generates an upward airflow. The self-contained suction filtration device 9 also includes a fixed insert A14, a fixed insert B17, a filter media tube A18, an air hole 19, a sealing cover 20, and a filter media tube B21. Multiple fixed inserts A14 are equidistantly inserted and fixed on the upper side of the center of the front end of the rectangular filter cover 13. The multiple fixed inserts A14 are arranged equidistantly from left to right. The center of the right end of the rectangular filter cover 13 is located at... Multiple fixed inserts B17 are equidistantly inserted and fixed on the lower side. The multiple fixed inserts B17 are arranged equidistantly from front to back. The equidistant arrangement allows the gas to flow evenly through each filter media tube when it flows inside the rectangular filter cover 13. Filter media tubes A18 are inserted into each of the multiple fixed inserts A14, and filter media tubes B21 are inserted into each of the multiple fixed inserts B17. The rear end of filter media tube A18 and the left end of filter media tube B21 are respectively attached to the inner wall of the rear end and the inner wall of the left end of the rectangular filter cover 13. This ensures that the gas flow path inside the rectangular filter cover 13 can fully pass through the filter media tubes, thereby improving the filtration efficiency.

[0027] like Figure 1 , Figure 4 and Figure 5As shown, sealing caps 20 are fitted onto the exterior of the front opening of filter media cylinder A18 and the exterior of the right opening of filter media cylinder B21. Both filter media cylinders A18 and B21 are densely covered with pores 19. These pores 19 provide a channel for the gas to fully contact the filter media, increasing the contact area between the gas and the filter media, thereby improving the adsorption efficiency. The sealing caps 20 prevent external dust, debris, etc., from entering when the filter media cylinders are not in use or are being replaced. The presence of zeolite inside the filter media cylinder affects the performance of the filter media. However, during normal operation, the sealing cap 20 helps maintain gas flow along the designed path within the filter media cylinder, ensuring filtration efficiency. Filter media cylinder A18 is filled with zeolite, while filter media cylinder B21 is filled with activated carbon particles. Zeolite has a large specific surface area and a unique crystal structure, exhibiting good adsorption performance for some large molecular impurities and certain harmful gases. When the gas stream containing impurities and harmful gases passes through filter media cylinder A18, the zeolite can adsorb some of the pollutants. Activated carbon granules provide preliminary filtration, while possessing superior adsorption capacity, particularly for odors, fine particles, and residual harmful gases. After preliminary filtration by filter media cylinder A18, the gas continues to flow through filter media cylinder B21, where activated carbon granules further purify the gas, achieving deep filtration of the waste gas. The fixed inserts A14 and B17 facilitate convenient and quick replacement of filter media cylinders A18 and B21. After a period of use, the adsorption capacity of filter media cylinders A18 and B21 will gradually increase. During descent, simply pull out the old filter media tube and insert the new one. No complicated operations or tools are required, greatly reducing maintenance costs and time and improving equipment efficiency. At the same time, the protective net 16 prevents foreign objects from entering the blower housing 15, avoiding blockage or damage to the blower and ensuring its long-term stable operation. This ensures that the entire machine tool protection mechanism maintains good protection and air purification effects during long-term operation, meeting the environmental protection and safety requirements in the processing of body parts.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
