Description

Technical Field

[0001] The utility model relates to the technical field of safe processing of machine tools, in particular to a structure which can stop equipment when a side plate is disassembled. Background Art

[0002] CNC machine tools are widely used in a variety of equipment processing technology fields due to their superior automation processing capabilities. During the maintenance of CNC machine tools, it is usually necessary to open their side panels to inspect and process their interior.

[0003] The CNC machine tools developed and produced in recent years have been equipped with side panel opening detection devices when they leave the factory to monitor the opening status of the side panels in real time and provide feedback to the operator to avoid the situation where the side panels are not closed and the machine is working directly. The reason is that if foreign objects enter the interior of the CNC machine tool during operation, it will cause the machine to malfunction, so the timely closing of the side panels is crucial. However, for some early-production CNC machine tools, there are no components installed inside to detect the opening status of the side panels in real time. This makes it easy for the operator to forget to close the side panels due to negligence, thereby increasing the probability of failure of the CNC machine tool. Therefore, for some early-production CNC machine tools, their safety performance needs to be further improved. Utility Model Content

[0010] As a further solution of the present invention: the cross section of the support plate is L-shaped, and reinforcing ribs are fixedly installed on the inner bending surface of the support plate.

[0011] As a further solution of the present invention, the light beam array covers the processing area of ​​the CNC machine tool.

[0012] As a further solution of the present invention: the first grating is an L-shaped grating composed of main grating 1, main grating 2 and main grating 3 in sequence, and the second grating is an L-shaped grating composed of sub-grating 1, sub-grating 2 and sub-grating 3 in sequence, and the two L-shaped gratings are respectively arranged on the corresponding right-angled sides of the opening of the CNC machine tool processing area.

[0013] As a further solution of the present invention: the support plate is made of steel.

[0014] As a further solution of the present invention: the support plate is made of stainless steel.

[0015] As a further solution of the present invention, the alarm device transmits information with the first grating and the second grating by wireless transmission.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This utility model utilizes a first and second grating to form a beam array, which, in conjunction with an alarm system, can monitor the opening and closing status of a CNC machine tool's side panels in real time. If a side panel is accidentally opened or removed, the beam array is blocked, the alarm immediately sounds, and the equipment shuts down. This effectively improves safety during CNC machine tool operation and prevents accidents caused by improper side panel opening.

[0018] 2. The support plate is placed in the non-processing area of ​​the CNC machine tool and fixed in a detachable manner, ensuring that the installation of the grating system will not interfere with the normal processing operation of the machine tool. At the same time, it is convenient for subsequent maintenance, replacement or adjustment of the grating position, thereby improving the flexibility and maintainability of the equipment.

[0019] 3. Bolts are used to connect the through holes on the support plate to the threaded holes in the non-machining area of ​​the CNC machine tool, providing a simple and stable fixing method, ensuring the stability of the support plate and the grating system on it, easy to install and disassemble, and convenient for equipment upgrades or maintenance.

[0020] 4. The combination of positioning pins and permanent magnets not only achieves rapid positioning and installation of the support plate, but also utilizes magnetic force to enhance the firmness of the connection, reduces the use of tools during installation, improves installation efficiency, and keeps the CNC machine tool neat and beautiful.

[0021] 5. The L-shaped cross-section support plate combined with the reinforcement rib design significantly enhances the strength and rigidity of the support plate, effectively resisting deformation caused by the weight of the grating system or external factors, ensuring the stability of the grating system and the accuracy of the beam array.

[0022] 6. The beam array covers the processing area of ​​the CNC machine tool, ensuring all-round monitoring of the machine tool working area. No matter which part of the side panel is opened, it can immediately trigger an alarm and shut down the machine, further improving the safety of machine tool operation.

[0023] 7. The design of the L-shaped grating adapts to the right-angle structure of the opening of the CNC machine tool processing area, realizes comprehensive monitoring of the opening and closing status of the side panels, improves the accuracy and reliability of the monitoring system, and reduces the number of gratings and installation complexity.

[0024] 8. The support plate is made of steel, which ensures the strength and durability of the support plate. It can withstand large loads and wear under long-term use, extending the service life of the equipment. At the same time, the cost of steel is relatively low, which helps to control the overall cost.

[0025] 9. The stainless steel support plate not only has high strength and good durability, but also has excellent corrosion resistance. It is suitable for various harsh industrial environments, effectively preventing structural damage caused by corrosion and ensuring the long-term stable operation of the grating system.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 During operation, two hydraulic cylinders 12 are installed above the main machine 11 to provide compression power for the machining area. Removable side panels 13 are installed at the telescopic ends of the hydraulic cylinders 12, as they require frequent maintenance. These panels can be removed to open and close an inspection hatch at the bottom of the hydraulic cylinders 12. To ensure maintenance safety, a corresponding light barrier is installed, which transmits information to monitor the closed state of the side panels 13 in real time.

[0030] The installation process of this utility model is as follows:

[0031] 1. Select the installation location:

[0032] Determine the non-machining area of ​​the CNC machine tool 1 and select the location where the support plate 2 will be installed, ensuring that the location will not interfere with the normal machining operation of the machine tool.

[0033] 2. Install the support plate:

[0034] Select the appropriate installation method based on the actual situation of CNC machine tool 1. If bolts are used, threaded holes are drilled in the non-machining area of ​​CNC machine tool 1 and through-holes are drilled in support plate 2. Bolts are inserted through the through-holes and threaded into the threaded holes to secure support plate 2 to CNC machine tool 1. If locating pins and permanent magnets are used, insert the locating pins into the locating holes on CNC machine tool 1 and use permanent magnets to magnetically attract support plate 2 to the machine tool.

[0035] 3. Install the grating:

[0036] The side panels on the main machine 11 and the main machine 11 itself cooperate to form an L-shaped side, and the side extends exactly along the opening direction of the processing area, so the first grating 3 is installed on the L-shaped side. Figure 1 As shown, a main grating 1 31 , a main grating 2 32 and a main grating 33 are sequentially installed along the L-shaped side from top to bottom, and the three main gratings cooperate in sequence to form an L-shaped first grating 3 .

[0037] At the same time, the two sides of the support plate 2 and the two sides of the main machine 11 cooperate with each other to form an L-shaped side, and the L-shaped side also extends along the opening direction of the processing area, so the second grating 4 is installed on the L-shaped side. Figure 1 As shown, the auxiliary grating 1 41 , the auxiliary grating 2 42 and the auxiliary grating 3 43 are sequentially installed along the L-shaped side from top to bottom, and the three auxiliary gratings cooperate in sequence to form the L-shaped second grating 4 .

[0038] The second grating 4 is parallel to the first grating 3 , and the distance between them is appropriately adjusted to form a beam array, ensuring that the beam array can cover the processing area of ​​the CNC machine tool 1 .

[0039] 4. Connect the alarm:

[0040] The alarm is connected to the first grating 3 and the second grating 4 by wireless connection, so that an alarm can be issued when the light beam array is blocked.

[0041] The use process of this utility model is as follows:

[0042] 1. Normal operation:

[0043] When the CNC machine tool 1 is operating normally, the light beam array between the first grating 3 and the second grating 4 remains intact, and the alarm does not sound. The machine tool can perform processing operations safely.

[0044] 2. Disassembly and inspection of side panel 13:

[0045] When the side panel 13 of the CNC machine tool 1 needs to be disassembled for maintenance or adjustment, once the side panel 13 is opened, the light beam formed between the main grating 2 32 and the auxiliary grating 2 42 is disconnected, and the alarm will light up at this time to remind the operator, and the CNC machine tool 1 will stop to remind the operator that the side panel 13 is in the open state at this time and needs to be closed as soon as possible.

[0046] 3. Emergency Response

[0047] After the operator sees the alarm, he will first check the alarm cause, whether it is because someone has put his hand into the working area during work, or the side panel 13 has been opened. After confirming the dangerous factor by checking, necessary maintenance or adjustment work can be continued.

[0048] 4. Reinstall the side panel 13:

[0049] After completing the maintenance or adjustment work, reclose the side panel 13 of the CNC machine tool 1. Ensure that the side panel 13 is completely closed and restored to its original position so that the beam array can be restored to its original position. At this point, the alarm will stop sounding and the CNC machine tool 1 can resume normal operation.

[0050] 5. Maintenance and care:

[0051] 5.1. Regular inspection: Check the light barriers and alarms regularly to ensure they are functioning properly. If any fault or damage is found, repair or replace them immediately.

[0052] 5.2. Cleaning and maintenance: Clean the dust and dirt on the grating and support plate 2 regularly to keep them clean and in good working condition.

[0053] 5.3. Calibration and adjustment: Calibrate and adjust the grating as needed to ensure the accuracy and stability of the beam array.

[0054] Through the above use process, it can be ensured that the CNC machine tool 1 can receive timely safety monitoring and alarms when the side panels 13 are removed, thereby improving the safety and reliability of the machine tool operation.

[0055] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
