Description
Technical Field
[0001] This utility model relates to the field of CNC lathe technology, and in particular to a CNC lathe with high safety. Background Technology
[0002] CNC lathes are among the most widely used CNC machine tools. They are primarily used for cutting internal and external cylindrical surfaces, internal and external conical surfaces with arbitrary cone angles, complex rotating internal and external curved surfaces, and cylindrical and conical threads on shaft-type or disc-type parts. They can also perform grooving, drilling, reaming, boring, and other machining operations. CNC machine tools automatically process parts according to pre-programmed machining procedures. We compile the machining process route, process parameters, tool movement trajectory, displacement, cutting parameters, and auxiliary functions into a machining program sheet according to the instruction codes and program format specified by the CNC machine tool. This program sheet is then recorded on a control medium and input into the CNC device of the CNC machine tool, thereby directing the machine tool to process the parts.
[0003] In actual use, existing CNC lathes may encounter dangerous situations such as flying debris and tool collisions when machining workpieces. Although they are equipped with safety doors, operators may forget to close them, which could pose a safety hazard.
[0004] A search of existing patents revealed a high-safety CNC lathe (publication number: CN221455179U). This utility model avoids the surface of the transparent observation window on the sliding door being scratched by flying debris when machining workpieces on a CNC lathe, and at the same time eliminates the risk of injury from flying debris, thus improving the safety of the CNC lathe.
[0005] While the aforementioned patents have achieved the goal of preventing flying debris, CNC lathes generate a lot of heat during the machining process, leading to excessively high temperatures inside the lathe chamber and affecting the machining efficiency of the CNC lathe.

[0019] (III) Beneficial Effects
[0020] This utility model provides a highly safe CNC lathe, which has the following beneficial effects:
[0021] 1. This highly safe CNC lathe, through the setting of moving components, protective doors, and monitoring components, uses proximity sensors to monitor the status of the protective door in real time during use, and a timer to set a delay threshold for the protective door to close. If the protective door is not closed after the preset time, a signal is sent to the PLC controller, which sends an operation command to the servo motor.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0029] Please see Figures 1 to 4 This utility model provides a technical solution: a highly safe CNC lathe, comprising a CNC lathe body 1, a moving component 2 fixedly connected to one edge of the CNC lathe body 1, two moving blocks 3 threadedly connected to the surface of the moving component 2, a protective door 4 fixedly connected to the top of each of the two moving blocks 3, a protective groove formed on one side of the protective door 4, an installation groove formed on the lower part of the inner wall of the protective groove, a monitoring component 5 fixedly installed inside the installation groove, a translation component 6 fixedly connected to the upper part of the other side of the CNC lathe body 1, a displacement ring frame 7 threadedly connected to the surface of the translation component 6, and a heat dissipation component 8 fixedly connected to the bottom end of the displacement ring frame 7.
[0030] The monitoring component 5 includes a proximity sensor 501 fixedly installed inside the mounting slot. One end of the proximity sensor 501 is electrically connected to a timer 502 via a power cord, and the other side of the timer 502 is electrically connected to a PLC controller 503 via a power cord. With the configuration of the moving component 2, the protective door 4, and the monitoring component 5, the proximity sensor 501 monitors the status of the protective door 4 in real time during use. The timer 502 is set with a delay threshold for closing the protective door. If the protective door 4 is not closed after the preset time, a signal is sent to the PLC controller 503. The PLC controller 503 sends an operation command to the servo motor 201. The forward and reverse threaded rod 202 rotates, driving the moving block 3 to move, thereby achieving the purpose of automatically closing the protective door 4. This avoids the operator forgetting to close the protective door 4, which may cause safety hazards and helps to improve the safety of the CNC lathe.
[0031] The translation component 6 includes a drive motor 601 fixedly connected to the upper part of the other side of the CNC lathe body 1. The output end of the drive motor 601 is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to a lead screw 602.
[0032] The heat dissipation component 8 includes a mounting bracket 801 fixedly connected to the bottom end of the displacement ring frame 7. A cooling fan 802 is rotatably connected inside the mounting bracket 801. With the arrangement of the translation component 6 and the heat dissipation component 8, when in use, the drive motor 601 and the cooling fan 802 are started, the lead screw 602 rotates, and the cooling fan 802 moves. The air generated by the cooling fan 802 dissipates heat from the running equipment inside the CNC lathe, thereby achieving the function of dissipating heat from multiple locations on the CNC lathe. This prevents the CNC lathe from generating a large amount of heat during the machining process, which would cause the temperature inside the lathe chamber to be too high, affecting the operation of the equipment and helping to improve the machining efficiency of the CNC lathe.
[0033] The moving component 2 includes a servo motor 201 fixedly connected to one side edge of the CNC lathe body 1. The output end of the servo motor 201 is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to a positive and negative threaded rod 202. The moving component 2 facilitates the movement of the protective door 4.
[0034] A movable groove 9 is provided on the lower front side of the main body 1 of the CNC lathe. The movable groove 9 is adapted to the movable block 3. The movable block 3 facilitates the movement of the protective door 4.
[0035] A limit groove 10 is provided on the upper part of the front of the CNC lathe body 1. The limit groove 10 is adapted to one end of the protective door 4. The limit groove 10 plays a limiting role.
[0036] One end of the lead screw 602 is rotatably connected to a stabilizing block 11. The top surface of the stabilizing block 11 is fixedly installed on one side of the inner top wall of the CNC lathe body 1. The stabilizing block 11 serves to connect the lead screw 602.
[0037] Support sleeves 12 are fixedly connected to all four sides of the bottom surface of the CNC lathe body 1. The bottom end of the support sleeves 12 is connected to the support legs 13 by screw thread. The support legs 13 serve to support the CNC lathe body 1.
[0038] A main control device 14 is provided on the other side of the CNC lathe body 1, and an alarm 15 is fixedly installed on the top surface of the CNC lathe body 1. The alarm 15 serves as a reminder.
[0039] In this invention, the working steps of the device are as follows:
[0040] First step: When in use, start the drive motor 601 and the cooling fan 802. The lead screw 602 rotates, moving the cooling fan 802. The air generated by the cooling fan 802 cools the running equipment inside the CNC lathe.
[0041] The second step: During use, the proximity sensor 501 monitors the status of the protective door 4 in real time, and the timer 502 sets the delay threshold for the protective door to close. If the protective door 4 is not closed after the preset time, a signal is sent to the PLC controller 503. The PLC controller 503 sends an operation command to the servo motor 201, and the positive and negative threaded rod 202 rotates to drive the moving block 3 to move.
