[0017] Please see Figures 1-4 This utility model provides an embodiment: a four-axis synchronous machining platform training device, including a device housing 1. Alarm rods 3 are provided at all four ends of the top surface of the device housing 1. An alarm component is provided at the top of each alarm rod 3. The alarm component is used to warn workers to leave the machining area. A rotary motor A12 is fixedly connected to the outer end face of the front end of the device housing 1.

The infrared camera mechanism 15 is also connected to a data recording module, which can record the number of times and the time of personnel accidentally entering the area, and generate a safety operation assessment report for practical training and assessment. The limit component includes a rotary motor B18. The output end of the rotary motor B18 is fixedly connected to a transmission rod 19. One end of the transmission rod 19 is rotatably connected to a lead screw B20. The two ends of the lead screw B20 are threadedly connected to positioning blocks 17. The two ends of the lead screw B20 extend to the outside of the two positioning blocks 17 and are rotatably connected to the device housing 1. When the rotary motor B18 drives the transmission rod 19 to rotate, the transmission rod 19, in conjunction with the lead screw B20, drives the two positioning blocks 17 to move.

[0018] Please see Figures 1-2In this embodiment, Y-axis guide seats 4 are provided on both sides of the top surface of the device housing 1 at the rear of the rotating frame 11. An X-axis guide seat 5 is movably connected to the inner side of the Y-axis guide seat 4. A Z-axis guide seat 6 is movably connected to the front end of the X-axis guide seat 5. A machining connection seat 7 is movably connected to the front end of the Z-axis guide seat 6. A machining mechanism 8 is fixedly connected to the bottom end of the machining connection seat 7.

The lead screw A10 is threadedly connected to the X-axis guide seat 5, the Z-axis guide seat 6, and the machining connection seat 7, respectively. When the three drive assemblies are started, the X-axis guide seat 5 moves inside the Y-axis guide seat 4, the Z-axis guide seat 6 moves inside the X-axis guide seat 5, and the machining connection seat 7 moves inside the Z-axis guide seat 6. Linear guides and slider pairs are provided inside the X-axis guide seat 5, the Y-axis guide seat 4, and the Z-axis guide seat 6.

For precise positioning, a control panel 2 is fixedly connected to one end of the outer casing 1. The control panel 2 is electrically connected to the alarm component, limit component, and drive component. When the device is powered on, the alarm component, limit component, and drive component can be controlled through the control panel 2. The control panel 2 is equipped with an emergency stop button, which is electrically connected to the rotary motor A12, drive component, and machining mechanism 8. After pressing the emergency stop button, all moving parts are immediately de-energized and stop running to ensure operator safety. The rotary motor A12, rotary motor B18, and servo motor are all self-locking motors (according to CN120320523A, a self-locking motor includes a housing, stator magnet, rotor, and motor shaft, with multiple corner sections in the polygonal cavity). The stator magnets are installed in pairs at the corners, with each stator magnet corresponding to the other at the corner. The arc-shaped surfaces of each stator magnet form an installation area to accommodate the rotor, optimizing the magnetic field distribution. Furthermore, grooves are formed on the arc-shaped surfaces of the stator magnets, dividing them into several stator poles. This breaks the magnetic reluctance of the air gap magnetic field, creating a discontinuous magnetic field and increasing the number of reluctance pairs, thus increasing the magnetic flux density of the rotor. The grooves on each stator magnet are in the same position to form a symmetrical stator pole layout, improving the symmetry of the air gap magnetic field. This results in a larger cogging torque, enhancing the motor's mechanical performance and self-locking capabilities. Compared to motors with a screw and nut drive structure, this design results in lower wear and a smaller size, making it suitable for compact designs.

[0019] Please see Figures 3-4 In this embodiment, positioning seats 14 are provided at both ends of the inner wall of the rotating frame 11. Bolt holes are provided in the center of the positioning seats 14. When the workpiece is placed inside the positioning seat 14, the four ends of the workpiece can be fixedly connected to the rotating frame 11 by bolts. A storage box 13 is movably connected to the lower part of the positioning seat 14 inside the outer shell 1 of the device. When the positioning seat 14 rotates, the positioning seat 14 can pour the waste generated by the processing workpiece into the inner side of the storage box 13. The bottom of the storage box 13 is provided with a slide rail, which can be pulled out horizontally along the inner side of the outer shell 1 of the device for easy cleaning of waste. A dust collection interface is also provided above the storage box 13, which can be connected to an external industrial dust collection device to reduce dust pollution. A bevel gear is provided at one end of the transmission rod 19 and at the center of the lead screw B20. When the rotary motor B18 drives the transmission rod 19 to rotate, the transmission rod 19 cooperates with the bevel gear. The screw B20 is a double-threaded screw with symmetrical threads at both ends. When the screw B20 rotates, it drives two positioning blocks 17 to move relative to each other. A light sensing mechanism 21 is provided at the top of the positioning block 17. The light sensing mechanism 21 is electrically connected to the rotary motor B18. The light sensing mechanism 21 includes a light sensor. When the positioning block 17 contacts the bottom end of the rotating frame 11, the light sensing mechanism 21 is blocked and can automatically shut down the rotary motor B18. The light sensing mechanism 21 is also connected to a PLC controller. The PLC controller is communicatively connected to the control panel 2. After the positioning block 17 completes its support for the rotating frame 11, the PLC automatically allows the machining program to start, realizing a closed-loop logic of positioning-confirmation-machining.

[0020] During operation, place the device in a suitable position, connect the power supply, start the device, and then place the workpiece to be processed on the top surface of the rotating frame 11. Secure the rotating frame 11 to the workpiece with bolts. Then, via the control panel 2, the three sets of drive components are activated sequentially. These three sets of drive components drive the X-axis guide seat 5, Z-axis guide seat 6, and processing connecting seat 7 to move horizontally, facilitating the positioning of the processing connecting seat 7 at the top of the workpiece. The workpiece is then processed by the processing mechanism 8. The rotating frame 11 is rotatably connected to the device housing 1 via the rotary motor A12. After one side of the workpiece has been processed, the rotating frame 11, in conjunction with the rotary motor A12, can rotate inside the device housing 1 to facilitate the device's processing of the workpiece. Double-sided processing is performed. When the rotating frame 11 is rotated to a suitable angle, the rotating motor B18, in conjunction with the transmission rod 19 and the lead screw B20, drives the two positioning blocks 17 to move to the bottom of the rotating frame 11, which facilitates the auxiliary positioning and support of the rotating frame 11 and improves the stability of the device. During the processing, the infrared camera mechanism 15 at the top of the alarm rod 3 scans the surrounding area. If the staff enters the processing area rashly, the infrared camera built into the infrared camera mechanism 15 will trigger the warning light 16, thereby warning the staff to leave the area. The infrared camera mechanism 15 is also connected to a data recording module, which can record the number of times and the time of personnel entering the area by mistake, and generate a safety operation assessment report for practical training and assessment. Compared to the prior art document CN219958381U, a modular integrated training device, the raw materials for manufacturing products are transported to the processing tank by a guide plate. The first horizontal push rod pushes the clamping plate to clamp and fix the raw materials to prevent the products from shifting during processing. Then, the second horizontal push rod is used to adjust the operating position of the processing mechanism, which has strong controllability. And CN213691037U A training platform for machining precision mechanical parts, which is equipped with a height-adjustable movable platform on the platform. The height of the movable platform can be adjusted by the handle at the bottom.

This application uses a rotary motor to drive the rotating frame to flip, which can automatically flip the workpiece to the other side after processing one side, without the need for manual disassembly and reclamping. Through the limit component, the positioning block automatically extends to provide support after the rotating frame is flipped into place, effectively preventing the deviation caused by vibration or gravity during processing, improving processing accuracy and equipment operation stability. In addition, it integrates an infrared camera mechanism and warning lights to form an active safety alarm system, which monitors the intrusion of personnel into the processing area in real time and triggers audible and visual alarms.
