DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Please refer to Figure 1 to Figure 2 The present application provides a switch mechanism, which is arranged between a protective component 100 and a door panel 200, and the door panel 200 is used to open or close the protective component 100. The switch mechanism includes: a guide component 300, which is at least partially arranged on the protective component 100, and the guide component 300 extends along the circumferential direction of the protective component 100. At least a portion of the door panel 200 is connected to the guide component 300 to guide the door panel 200 during the opening and closing process of the door panel 200; a limiting component 400, which is arranged on the protective component 100, and at least a portion of the limiting component 400 is in contact with the door panel 200 to place the door panel 200 in an open position; a cleaning component 500, which is arranged on the door panel 200, and at least a portion of the cleaning component 500 is in contact with the surface of the protective component 100 to clean the surface of the protective component 100 during the movement of the door panel 200.

[0024] According to the switch mechanism provided in the present application, it is arranged between the protective component 100 and the door panel 200, and the door panel 200 is used to open or close the protective component 100. The switch mechanism includes a guide component 300, a limiting component 400 and a cleaning component 500. The guide component 300 is at least partially arranged on the protective component 100, and the guide component 300 extends along the circumferential direction of the protective component 100. At least a portion of the door panel 200 is connected to the guide component 300 to guide the door panel 200 during the opening and closing process of the door panel 200; the limiting component 400 is arranged on the protective component 100, and at least a portion of the limiting component 400 is in contact with the door panel 200 to place the door panel 200 in an open position; the cleaning component 500 is arranged on the door panel 200, and at least a portion of the cleaning component 500 is in contact with the surface of the protective component 100 to clean the surface of the protective component 100 during the movement of the door panel 200. By setting the guide component 300, the moving trajectory of the door panel 200 during the opening and closing process is precisely controlled, ensuring that the door panel 200 is opened and closed smoothly and accurately, greatly improving the stability and reliability of the switch. The limit component 400 ensures that the door panel 200 will not exceed the predetermined position when opening, effectively preventing mechanical failure or collision accidents caused by excessive opening of the door panel 200. The anti-collision system further improves the safety level, can timely detect the approach of the door panel 200 to other components or obstacles, avoid potential collision risks, and protect the safety of equipment and operators. The cleaning component 500 cleans the surface of the protective component 100 when the door panel 200 moves, effectively preventing aluminum chips, cutting fluid or other debris generated during the processing from adhering to the surface of the equipment, reducing the maintenance workload, and avoiding equipment failures caused by debris, thereby improving the operating efficiency and service life of the equipment. The design of the guide component 300 and the limit component 400 reduces the jamming and collision of the door panel 200 during the opening and closing process, reduces the failure rate of the equipment, and reduces unplanned downtime.

[0025] In the first embodiment provided by the present application, the guide component 300 includes a convex strip 310, which is arranged on the protective component 100 and protrudes relative to the surface of the protective component 100, and the convex strip 310 extends along the circumferential direction of the protective component 100; the door panel 200 is provided with a guide groove 210, and at least part of the convex strip 310 is arranged in the guide groove 210, so that the convex strip 310 cooperates with the guide groove 210 to guide the door panel 200. The cooperation between the convex strip 310 and the guide groove 210 provides a precise track for the movement of the door panel 200, ensuring that the door panel 200 moves smoothly along the predetermined path during the opening and closing process, avoiding deviation from the track or jamming, and improving the accuracy of the switch mechanism and the continuity of operation. The structural design of the convex strip 310 and the guide groove 210 makes the contact surface relatively small, reduces friction, prolongs the service life of the guide component 300 and the door panel 200, and reduces the maintenance frequency and cost caused by wear. The close fit between the convex strip 310 and the guide groove 210 limits the unexpected displacement of the door panel 200, enhances the stability during the opening and closing process, and reduces the potential safety hazards caused by the unstable movement of the door panel 200, such as collision or jamming caused by accidental opening or incomplete closing. Compared with the complex guide mechanism, the combined structure of the convex strip 310 and the guide groove 210 is simpler and easier to install and adjust, which reduces the complexity of the overall structure, reduces potential failure points, and improves the reliability and fault recovery speed of the equipment. The design of the convex strip 310 minimizes the space occupied by the guide structure on the protective component 100, and the guide groove 210 is integrated in the door panel 200. This design not only optimizes the utilization of the internal space of the machine tool, but also keeps the appearance of the equipment neat, which helps to improve the overall design of the equipment and the comfort of the operating environment. The combination of the convex strip 310 and the guide groove 210 can adapt to door panels 200 of different sizes and weights. By adjusting the size and shape of the convex strip 310 and the depth and width of the guide groove 210, the guiding function for door panels of various devices can be realized, thereby enhancing the adaptability and compatibility of the guiding structure.

[0026] In the second embodiment provided in the present application, a guide groove 210 is provided on the door panel 200, and the guide component 300 includes: a guide top screw, which is arranged at intervals along the circumferential direction of the protective component 100 and forms a sliding fit with the guide groove 210 on the door panel 200. The precise fit between the guide groove 210 and the guide top screw ensures the linear motion of the door panel 200 during the opening and closing process, reduces the possibility of lateral displacement or jamming of the door panel 200, and thus improves the accuracy and reliability of the switch action. The guide top screw is arranged at intervals along the circumferential direction of the protective component 100, which can evenly distribute the force of the door panel 200 during the movement process, prevent wear or deformation caused by excessive local force, and improve the stability and durability of the structure. The matching design of the guide groove 210 and the guide top screw reduces friction and wear during the movement process, prolongs the service life of the equipment, and at the same time, due to the presence of the cleaning component 500, further reduces the additional wear caused by impurities, thereby reducing the frequency and cost of equipment maintenance and replacement of parts. The door panel 200 moves smoothly under the guidance of the guide groove 210 and the guide screw, avoiding accidents caused by jamming or abnormal movement, such as collision, and enhancing the operational safety of the equipment and the safety of the working environment. The guide component 300 cooperates with the guide groove 210 on the door panel 200, making the opening and closing process of the door panel 200 smoother and faster, reducing the processing pause caused by the delay of opening and closing the door, and improving the operating efficiency of the equipment and the overall processing rhythm.

[0027] In the third embodiment provided in the present application, a positioning pulley 320 is further provided on the door panel 200, and a slide groove is provided on the surface of the protective component 100. The positioning pulley 320 moves along the slide groove, which can significantly reduce the shaking and friction of the door panel 200 during the opening and closing process, thereby ensuring the smoothness of the door panel opening and closing and the accuracy of positioning, and avoiding the switching irregularities or jamming caused by shaking. The cooperation between the pulley and the slide groove reduces the direct contact between the door panel 200 and the protective component 100, reduces the risk of wear and damage, extends the service life of the door panel and the protective component, and reduces the frequency of maintenance and replacement of parts. Guided by the pulley and the slide groove, the door panel 200 can move along a predetermined trajectory, effectively preventing the deviation of the door panel during the movement process, and avoiding the potential safety hazards of operator injury or other equipment damage caused by this. The smooth opening and closing and precise positioning of the door panel 200 reduce the waiting time of the operator, improve work efficiency, and also reduce the noise generated during the operation of the equipment, providing a more comfortable working environment for the operator.

[0028] In the specific implementation process, Figure 1As shown, the switch mechanism also includes a control module, and the limit component 400 includes: a limit switch 410, which is arranged on the protective component 100 and connected to the control module signal, and the door panel 200 contacts the limit switch 410, so that the limit switch 410 sends a position signal of the door panel to the control module, and the control module controls the door panel 200 to stop moving. The use of the limit switch 410 and the control module allows the opening and closing positions of the door panel 200 to be accurately controlled. When the door panel 200 moves to the preset limit position, the limit switch 410 will be triggered and immediately send a signal to the control module, and the control module will then stop the movement of the door panel 200 to ensure that it stops at the desired position accurately. This high-precision control reduces faults caused by position deviation and improves the reliability and efficiency of the equipment. The signal of the limit switch 410 is automatically processed by the control module, eliminating the need for manual operation or manual judgment of the position, so that the equipment can operate more efficiently and safely. Automated control not only speeds up the processing process, but also reduces the workload of the operator, reduces human errors, and improves overall production efficiency. The combination of the limit switch 410 and the control module forms an effective safety barrier. Once the unexpected movement or abnormal position of the door panel 200 is detected, the control module can respond quickly and stop the movement of the door panel 200 in time to avoid possible collisions or other safety accidents, providing additional safety protection for the operator and the equipment itself. The control module can continuously monitor the status of the limit switch 410, and any fault or abnormal signal of the switch can be immediately identified and recorded, thereby helping maintenance personnel to quickly locate the problem, reduce troubleshooting time, and improve the maintenance efficiency and availability of the equipment. When the door panel 200 reaches the limit position, the control module can immediately cut off unnecessary power supply, which not only improves the safety of the equipment, but also optimizes energy use, reduces energy waste, is beneficial to environmental protection and reduces operating costs. The integration of the limit switch 410 and the control module simplifies the operation process, reduces the complexity in the operation, and enables the operator to focus more on the core tasks rather than the fine-tuning or monitoring of the equipment, further improving the overall operating efficiency and productivity of the machining center or gantry processing equipment.

[0029] In the present application, the protective component 100 includes a top surface 101 and a side surface 102 connected to each other; the door panel 200 includes a first plate body 220 and a second plate body 230 connected to each other, the first plate body 220 is located on the top surface 101, and the second plate body 230 is located on the side surface 102, and the cleaning component 500 includes: a first cleaning body 510, which is arranged on the first plate body 220 and is in contact with the top surface 101; a second cleaning body 520, which is arranged on the second plate body 230 and is in contact with the side surface 102. Since the first cleaning body 510 is arranged on the first plate body 220 and is in contact with the top surface 101, and the second cleaning body 520 is arranged on the second plate body 230 and is in contact with the side surface 102, this design enables the cleaning component 500 to fully clean the top surface 101 and the side surface 102 of the protective component 100 during the opening and closing process of the door panel 200, effectively preventing aluminum chips, cutting fluid or other impurities generated during the processing from accumulating on the surface of the equipment, thereby maintaining the cleanliness of the equipment and the sanitation of the operating environment. The first cleaning body 510 and the second cleaning body 520 automatically clean the door panel 200 when it moves, which reduces the frequency and workload of manual regular cleaning, saves maintenance time and cost, improves the maintenance efficiency of the equipment, and also avoids the degradation of equipment performance due to negligent maintenance. By continuously removing impurities on the top surface 101 and the side surface 102, the cleaning component 500 helps to maintain the stable operation of the equipment, prevents the guide rails, sensors or other key components from being interfered with by foreign objects such as aluminum chips, thereby avoiding equipment failures and improving the reliability and service life of the equipment. The regular automatic cleaning function keeps the surface of the protective component 100 clean, which not only improves the appearance of the equipment, but also reduces the interference with equipment operation or visual inspection caused by surface stains, providing a clearer and safer visual environment for the operator. The clean equipment surface reduces the accidental jamming or obstruction of movement of sliding parts, reduces the potential safety hazards during operation, and ensures the safety and smoothness of equipment operation.

[0030] Preferably, the first cleaning body 510 and / or the second cleaning body 520 is a cleaning brush. The cleaning brush has good elasticity and can fit tightly to the surface of the protective component 100, effectively removing aluminum chips, dust and cutting fluid residues generated during the processing, improving the cleaning efficiency, and ensuring that the surface of the equipment is clean and tidy. The structure of the cleaning brush can flexibly adapt to various surface shapes and roughness, whether it is a flat surface, a curved surface or a surface with small grooves or holes, it can achieve effective cleaning, thereby improving the scope of application and cleaning effect of the cleaning component 500. Compared with hard materials, the cleaning brush causes very little wear on the surface of the protective component 100, can maintain the integrity and aesthetics of the equipment surface for a long time, and extend the service life of the equipment.

[0031] In the specific implementation process, the switch mechanism also includes: a blowing component 600, which is arranged at the top of the protective component 100, and the blowing component 600 is arranged relative to the top surface 101 of the protective component 100 to blow air to the top surface 101 to clean the top surface 101; wherein the blowing component 600 is movably arranged along a predetermined trajectory. The setting of the blowing component 600 realizes the automatic cleaning of the top surface 101 without manual intervention, reduces the downtime caused by cleaning operations, and thus improves the processing efficiency and production rhythm of the equipment. By regularly cleaning the top surface 101, it is possible to prevent the accumulation of impurities such as aluminum chips and cutting fluids, and prevent these impurities from being sucked into the guide component 300 or the limit component 400 when the equipment is running, thereby reducing the malfunctions or safety hazards caused by this, such as jamming, wear or short circuit. The automatic cleaning function reduces the maintenance requirements of the top surface 101, reduces the frequency and cost of equipment maintenance caused by the accumulation of impurities, and extends the service life of the equipment. Blowing cleaning can not only remove impurities from the top surface 101, but also improve the working environment around the equipment, reduce the splashing of dust and liquid, and provide operators with a cleaner and safer operating space. The blowing component 600 moves along a predetermined trajectory and can accurately clean every corner of the top surface 101, avoiding the waste of air or compressed gas caused by excessive blowing, and saving production costs. Since the blowing component 600 is movable, its blowing trajectory and strength can be adjusted according to different equipment or working conditions to adapt to the cleaning needs in various complex environments. Long-term automatic cleaning keeps the top surface 101 clean, reduces equipment failures caused by impurities, and improves the overall operating reliability and stability of the equipment.

[0032] The air blowing component 600 integrated in the switch mechanism, through its movable setting and automatic cleaning of the top surface 101, not only improves the cleanliness and working environment of the equipment, but also significantly improves the operating efficiency, safety and reliability of the equipment.

[0033] Preferably, the air blowing component 600 is an air blowing pipe, and the switch mechanism further includes: a driving component, which is arranged on the plane of the protective component 100, the driving component is rotatably arranged around a predetermined axis, and the driving component is connected to the air blowing pipe to drive the air blowing pipe to rotate. By rotating the air blowing pipe through the driving component, compressed air or other clean gas can be directly blown to the surface of the tool magazine door and the tool holder, effectively removing metal chips, dust and other impurities generated during the processing, reducing the need for manual cleaning, and improving production efficiency and the cleanliness of the working environment. Regular automatic air blowing cleaning can reduce tool clamping failures caused by debris, prevent the tool magazine door from being stuck by foreign objects when opening and closing, thereby reducing the equipment failure rate and enhancing the safety and reliability of operation. The automatic cleaning function of the air blowing component 600 reduces the complexity of equipment maintenance, and the operator does not need to frequently stop the machine for manual cleaning, which reduces maintenance costs and downtime, and also reduces the risk of maintenance personnel contacting dangerous parts. Keeping the tool magazine door and tool holder clean avoids the increase of door panel movement resistance caused by the accumulation of cutting fluid and aluminum chips, thereby ensuring the rapid opening and closing of the door panel 200 and the smooth replacement of tools, further improving the processing capacity and production efficiency of the equipment. By timely removing impurities on the tool magazine door and tool holder, the wear and corrosion of components are reduced, thereby extending the service life of the equipment and reducing long-term operating costs.

[0034] Specifically, the driving component is a driving motor, a driving gear is arranged on the driving motor, the air blowing pipe is passed through the driven gear, the driving gear and the driven gear are meshed with each other, thereby driving the air blowing pipe to rotate.

[0035] The switch mechanism also includes: a proximity sensor, which is arranged on the protective component 100, and at least part of the door panel 200 is in contact with the proximity sensor so that the door panel 200 is in a closed position. The proximity sensor can accurately detect the position of the door panel 200 relative to the protective component 100, and automatically identify whether the door panel 200 is completely closed in place, without manual inspection, thereby improving the automation and efficiency of the operation. The proximity sensor monitors the position state of the door panel 200 in real time. Once it is detected that the door panel 200 is not completely closed or has an abnormal deviation in the closed position, the system will immediately take measures, such as stopping the operation of the equipment or issuing an alarm, effectively preventing the splashing of debris during the processing process or the operator from mistakenly entering the dangerous area due to the loose closing of the door panel 200, and significantly improving the safety performance of the equipment. Through the detection of the proximity sensor, problems that may occur during the closing process of the door panel 200, such as jamming or incomplete closure, can be discovered in time, thereby avoiding equipment failures caused by these problems, reducing unplanned downtime, and improving production efficiency.

[0036] The present application also provides a machine tool, including a tool magazine, a tool magazine door panel and a switch mechanism, wherein the switch mechanism is arranged between the tool magazine and the tool magazine door panel, and the switch mechanism is the switch mechanism of the above embodiment.

[0037] In the present application, compressed air is used as a driving medium to drive the door panel 200 through a cylinder or a pneumatic motor. The advantages of pneumatic drive are fast response speed, suitable for high-speed switching operation, relatively low cost and simple maintenance. The action of the cylinder can be controlled by a solenoid valve to realize automatic switching operation, and the pneumatic drive can still keep the door panel 200 in the current position in the event of a sudden power failure, providing a certain degree of safety.

[0038] In order to further protect the tool magazine, a chip cover 700 is also provided on the top surface of the tool magazine. The chip cover 700 can effectively block metal chips, cutting fluid and other impurities generated during the processing, prevent them from entering the tool magazine, and cause pollution and damage to the tool, tool magazine door switch mechanism and other precision parts. This not only protects the internal components, but also maintains the processing accuracy and performance of the equipment. The chip cover 700 reduces the chance of the tool being exposed to impurities, avoids wear and corrosion on the tool surface, helps to extend the service life of the tool, and reduces the cost of tool replacement. Preferably, when the door panel is in the closed position, a gap is provided between the chip cover 700 and the first plate body 220 of the door panel so that the door panel can move smoothly.

[0039] In actual use, Figure 3 As shown, when the CNC (numerical control lathe) issues a door opening command, the electric cylinder of the solenoid valve is activated, and the tool magazine door opens under the action of the top screw guide. The limit switch is used to sense when the tool magazine door is opened to the right position, and the tool changing procedure is performed on weekdays. After the tool changing procedure is completed, the tool magazine door is closed. When the limit switch detects that the tool magazine door is opened abnormally, an alarm is issued to prompt the staff to handle it.

[0040] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0041] According to the switch mechanism provided in the present application, it is arranged between the protective component 100 and the door panel 200, and the door panel 200 is used to open or close the protective component 100. The switch mechanism includes a guide component 300, a limiting component 400 and a cleaning component 500. The guide component 300 is at least partially arranged on the protective component 100, and the guide component 300 extends along the circumferential direction of the protective component 100. At least a portion of the door panel 200 is connected to the guide component 300 to guide the door panel 200 during the opening and closing process of the door panel 200; the limiting component 400 is arranged on the protective component 100, and at least a portion of the limiting component 400 is in contact with the door panel 200 to place the door panel 200 in an open position; the cleaning component 500 is arranged on the door panel 200, and at least a portion of the cleaning component 500 is in contact with the surface of the protective component 100 to clean the surface of the protective component 100 during the movement of the door panel 200. By setting the guide component 300, the moving trajectory of the door panel 200 during the opening and closing process is precisely controlled, ensuring that the door panel 200 is opened and closed smoothly and accurately, greatly improving the stability and reliability of the switch. The limit component 400 ensures that the door panel 200 will not exceed the predetermined position when opening, effectively preventing mechanical failure or collision accidents caused by excessive opening of the door panel 200. The anti-collision system further improves the safety level, can timely detect the approach of the door panel 200 to other components or obstacles, avoid potential collision risks, and protect the safety of equipment and operators. The cleaning component 500 cleans the surface of the protective component 100 when the door panel 200 moves, effectively preventing aluminum chips, cutting fluid or other debris generated during the processing from adhering to the surface of the equipment, reducing the maintenance workload, and avoiding equipment failures caused by debris, thereby improving the operating efficiency and service life of the equipment. The design of the guide component 300 and the limit component 400 reduces the jamming and collision of the door panel 200 during the opening and closing process, reduces the failure rate of the equipment, and reduces unplanned downtime.
