Description

Technical Field

[0001] This utility model relates to the field of practical training equipment technology, and in particular to a multi-axis synchronous and flying shear motion control training device. Background Technology

[0002] A multi-axis synchronous and flying shear motion control training device is provided to students for practical training in servo and stepper motor motion control. It can realize motor speed control, positioning control, and two-axis synchronous control, typical flying shear cam control, and gear synchronous control. Through this experimental equipment, students can become familiar with motion control principles, servo motor motion control, PLC motion control algorithms, motion control configuration and monitoring technology, and effective methods for advanced motion control algorithms.

[0003] This training device not only meets the needs of training motor speed control and positioning control, but also realizes multi-axis synchronous cam control and gear control. It can also conduct training in color recognition, laser switching, etc. Multi-axis synchronous control can be realized through PLC, and advanced motion control algorithms can be implemented through PLC.

[0004] Current training devices do not achieve two synchronous motion control. They generally achieve either dual-disc gear synchronization or flying shear synchronization. The experimental devices are generally large in size, occupy a lot of space, and the motors cannot be easily replaced. Only one type of motor can be used, which makes it impossible to carry out development testing and scientific research verification. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a multi-axis synchronous and flying shear motion control training device. It has the function of completing training on two typical multi-axis synchronous control modes, flying shear and dual disc, on the same set of physical devices, and the function of quick replacement and precise positioning of motors with different models. It alleviates the problems of single function and high teaching cost of existing equipment, as well as the disadvantages of fixed motors in existing devices that cannot be flexibly adapted to multiple motors for testing and verification. It significantly improves teaching efficiency and depth and greatly enhances the practicality of the equipment.

[0006] The objective of this utility model is achieved through the following technical solution: A multi-axis synchronous and flying shear motion control training device includes a mounting plate. Motor 1 and Motor 2 are mounted on the mounting plate. A driving synchronous pulley and a synchronous disk 1 are coaxially mounted on the output shaft of Motor 1. A flying shear and a synchronous disk 2 are coaxially mounted on the output shaft of Motor 2. The driving synchronous pulley is connected to the driven synchronous pulley through a synchronous belt. Synchronous disk 1 and synchronous disk 2 are mounted parallel to each other and staggered on the same side of the mounting plate. Laser sensor 1, laser sensor 2 and laser sensor 3 are mounted on the side of the mounting plate.

[0007] In one optional implementation, a color block is provided on the timing belt, and a color mark sensor for detecting the color block is correspondingly provided on the mounting plate.

[0008] In one alternative implementation, motor one and motor two are mounted on a mounting plate via a modular motor interface, which includes a base flange and an adapter plate.

[0009] In one optional embodiment, the base flange has a through hole through which the motor shaft passes, and an annular positioning stop is provided on the side facing the adapter plate. The adapter plate has a positioning inner hole that mates with the annular positioning stop on the side facing the base flange.

[0010] In one optional embodiment, the base flange is provided with four threaded blind holes, and the adapter plate is provided with light holes corresponding to the threaded blind holes. The adapter plate is fixed to the base flange by passing through the light holes and screwing into the threaded blind holes with hexagon socket screws.

[0011] In one optional implementation, an emergency stop button is provided in the upper right corner of the mounting plate. The emergency stop button is connected to the control system and is used to cut off the motor power and stop the system in an emergency.

[0012] In one optional implementation, the relative axial positions between the active synchronizing pulley and the first synchronizing disc, and between the flying shears and the second synchronizing disc, are determined by spacer sleeves fitted on the shaft.

[0013] In one optional embodiment, the first synchronization disk is a completely white disk surface with two synchronization holes, and the middle area of ​​the second synchronization disk surface is a transparent part, the outer ring area is a white part with two synchronization holes.

[0014] In one optional embodiment, the installation position of laser sensor one is such that its detection end is aligned only with the surface of synchronization disk one, the installation position of laser sensor three is such that its detection end is aligned only with the surface of synchronization disk two, and the installation position of laser sensor two is such that its detection end is aligned with the overlapping area of ​​synchronization disk one and synchronization disk two.

[0015] In one optional implementation, laser sensor one is used to perform initial positioning of synchronization disk one, laser sensor three is used to perform initial positioning of synchronization disk two, and laser sensor two is used to verify the synchronization status by detecting the synchronization hole when synchronization disk one and synchronization disk two are running synchronously.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By integrating the active synchronizing wheel and synchronizing disk coaxially into motor one, and integrating the flying shear and synchronizing disk two coaxially into motor two, the hardware reuse structure realizes the training function of two typical multi-axis synchronous control modes, flying shear and dual disk, on the same set of physical devices. This alleviates the problems of single function and high teaching cost of existing equipment, and helps students to intuitively compare the differences between different control algorithms, significantly improving teaching efficiency and depth.

[0017] 2. By adopting a modular motor interface consisting of a base flange and an adapter plate, the quick replacement and precise positioning of different motor models are realized, which alleviates the drawbacks of the existing device where the motor is fixed and cannot be flexibly adapted to various motors for testing and verification. This is beneficial to expanding the equipment from a single teaching and training platform to an open R&D and testing platform, greatly enhancing the practicality of the equipment.

[0018] 3. This device is based on the improvement of existing equipment, so the improvement cost is relatively low and it will not cause a large amount of existing equipment to be discarded. It ensures the processing effect while reducing the investment in improvement costs, making it suitable for large-scale production. Attached Figure Description

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Unless otherwise specified, the materials and equipment used in this embodiment are all commercially available. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0022] Please refer to Figure 1-5 A multi-axis synchronous and flying shear motion control training device includes a mounting plate 1. A motor 1 2 and a motor 2 3 are mounted on the mounting plate 1. A driving synchronous pulley 6 and a synchronous disk 1 12 are coaxially mounted on the output shaft of motor 1 2. A flying shear 10 and a synchronous disk 2 13 are coaxially mounted on the output shaft of motor 2 3. The driving synchronous pulley 6 is connected to the driven synchronous pulley 7 through a synchronous belt 8. The synchronous disk 1 12 and the synchronous disk 2 13 are mounted parallel to and offset on the same side of the mounting plate 1. A laser sensor 1 15, a laser sensor 2 16, and a laser sensor 3 17 are mounted on the side of the mounting plate 1.

[0023] In a preferred embodiment of this utility model, a color block 9 is provided on the synchronous belt 8, and a color mark sensor 11 for detecting the color block 9 is correspondingly provided on the mounting plate 1, which is beneficial to provide accurate material positioning signals for the flying shear unit.

[0024] In a preferred embodiment of this utility model, motor 2 and motor 3 are mounted on mounting plate 1 via modular motor interface 4. Modular motor interface 4 includes base flange 401 and adapter plate 402, which decouples the motor from mounting plate 1. Motors with different flange specifications can be quickly adapted by replacing different adapter plates 402.

[0025] In a preferred embodiment of this utility model, the base flange 401 has a through hole at its center for the motor shaft to pass through, and an annular positioning stop is provided on the side facing the adapter plate 402. The adapter plate 402 has a positioning inner hole that mates with the annular positioning stop on the side facing the base flange 401. Through the precise fit of the "stop-inner hole", a unique and accurate radial positioning reference is provided for each installation of the motor, which fundamentally ensures the concentricity of the motor shaft and the load and eliminates human installation errors.

[0026] In a preferred embodiment of this utility model, the base flange 401 is provided with four threaded blind holes, and the adapter plate 402 is provided with open holes corresponding to the threaded blind holes. By passing through the open holes and screwing into the threaded blind holes, the adapter plate 402 is fixed to the base flange 401, providing a robust, reliable and easy-to-disassemble fastening solution.

[0027] In a preferred embodiment of this utility model, an emergency stop button 18 is provided in the upper right corner of the mounting plate 1. The emergency stop button 18 is connected to the control system and is used to cut off the motor power and stop the system in an emergency, which helps to ensure the safety of the training process.

[0028] In a preferred embodiment of this utility model, the relative axial positions between the active synchronizing wheel 6 and the first synchronizing disc 12, and between the flying shears 10 and the second synchronizing disc 13, are determined by the spacer sleeve 5 fitted on the shaft, which is beneficial for adjustment and maintenance and ensures the precision and consistency of mechanical assembly.

[0029] In a preferred embodiment of this utility model, the first synchronization disk 12 has a completely white disk surface and two synchronization holes 14. The middle area of ​​the second synchronization disk 13 is transparent, and the outer ring area is white and has two synchronization holes 14. The transparent middle area of ​​the second synchronization disk 13 facilitates observation of the movement of the flying scissors 10 inside. The synchronization holes 14 facilitate verification of the synchronization status with the sensor.

[0030] In a preferred embodiment of this utility model, the installation position of laser sensor 15 ensures that its detection end is aligned only with the surface of synchronous disk 12, the installation position of laser sensor 17 ensures that its detection end is aligned only with the surface of synchronous disk 13, and the installation position of laser sensor 16 ensures that its detection end is aligned with the overlapping area of ​​synchronous disk 12 and synchronous disk 13, thus ensuring that the detection target of each sensor is clear and that they do not interfere with each other.

[0031] In a preferred embodiment of this utility model, laser sensor 15 is used for initial positioning of synchronous disk 12, laser sensor 17 is used for initial positioning of synchronous disk 13, and laser sensor 16 is used to verify the synchronization state by detecting the synchronization hole 14 when synchronous disks 12 and 13 are running synchronously. The operating effect of the abstract motion control algorithm (electronic gear / electronic cam) is transformed into a concrete, visible, and measurable photoelectric pulse signal. Students can intuitively judge the synchronization accuracy by observing whether the pulse of laser sensor 16 is uniform and stable, thus closely combining theoretical knowledge with physical phenomena, greatly reducing the difficulty of learning, and improving the teaching effect and depth.

[0032] When using this device, the system first performs initial positioning. After startup, motor 2 drives the active synchronous wheel 6 and synchronous disk 12 to rotate, while motor 3 drives the flying shears 10 and synchronous disk 13 to rotate. Color mark sensor 11 detects the color block 9 on the synchronous belt 8 as the feeding reference. At the same time, laser sensor 17 detects the synchronization hole 14 of synchronous disk 12, and laser sensor 15 detects the change in the transparent part in the middle of synchronous disk 13, establishing the reference phase of the two respectively. In flying shear mode, when color mark sensor 11 is triggered again, the control system immediately drives motor 3 to execute the electronic cam curve, so that the flying shears 10 and synchronous belt 8 can accurately and synchronously complete the cutting. In gear synchronization mode, the system sets the electronic gear ratio, so that synchronous disk 13 strictly follows synchronous disk 12 in rotation. At this time, laser sensor 16 detects the pulse of the synchronization hole 14 on the outer ring of synchronous disk 13 and compares it with the spindle pulse detected by laser sensor 17, thus visually verifying the synchronization accuracy. The entire process can be ensured by the emergency stop button 18.

[0033] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0034] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
