Description

Technical Field

[0001] The present invention relates to the technical field of teaching equipment, in particular to an AI-integrated multifunctional education and training workbench. Background Art

[0002] Artificial intelligence (AI) is a major branch of computer science, aiming to enable autonomous machine decision-making and task execution by simulating, extending, and expanding human intelligent behavior. Its technical system encompasses core algorithms such as machine learning, deep learning, and neural networks, and combines big data analysis and computing power to enable the system to possess environmental perception, logical reasoning, pattern recognition, and adaptive optimization capabilities. AI technology has been widely used in smart manufacturing, smart healthcare, autonomous driving, and other fields, driving the intelligent transformation of various industries by automating complex tasks, optimizing resource allocation, and improving decision-making efficiency. In the field of education, the implementation of AI technology has given rise to the demand for professional talent training. As a practical platform integrating AI algorithm models, industry scenario data, and an interactive development environment, the educational training workbench can provide learners with an environment for algorithm training, system deployment, and effect verification in simulated business scenarios. Through modular course design and real-world case-driven development, it builds a complete technical chain from theoretical cognition to engineering implementation, providing talent support for the industrial application of AI technology.

[0003] When testing the mechanical properties of materials, existing AI education and training workbenches, especially when conducting simulated training tests on the fatigue strength of flexible components such as plastic pipe fittings, traditional training and testing equipment generally adopts a unidirectional load loading method, and constrains the motion trajectory of the specimen to a single axial direction through a mechanical limit device. This method can only simulate reciprocating motion along a preset straight line trajectory. Although it can meet the basic axial fatigue strength test requirements, it cannot truly restore the multi-dimensional composite stress state that the pipe fittings are subjected to under actual working conditions. Since plastic pipe fittings in actual engineering applications are often in a multi-physical field coupling environment such as bending, torsion, and stretching, there is a significant deviation between the data tested by existing testing technologies and the actual service performance. Especially when evaluating material durability indicators, the traditional unidirectional loading method cannot effectively capture the failure mechanism of plastic pipe fittings under complex stress paths, which may make it difficult for students to establish an intuitive understanding of the material failure mechanism under multi-axial loads through experiments, limiting their practical understanding of composite fatigue damage theory.

DETAILED DESCRIPTION

[0030] The following will be combined with the Figure 1 To the attached Figure 9 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0031] The present invention provides a technical solution: an AI fusion multifunctional education and training workbench, comprising a training table 100, a training platform 200, an operation panel 300 and a training screen 400, wherein the training platform 200 is arranged in the middle of the upper surface of the training table 100, the operation panel 300 is installed at the outer end of the training platform 200, and is used to display circuit principles and control logic, and the training screen 400 is installed on the upper surface of the training platform 200, and is used to dynamically demonstrate teaching content, support touch interaction and multi-person collaborative training, wherein the education and training workbench integrates an AI intelligent control center, realizes multimodal data fusion and real-time decision-making through an edge computing module, and the training screen 400 supports voice command control, and recognizes the circuit diagram gesture annotation of the operation panel (300) through a computer vision module, and automatically associates it with the kinematic model of the mechanical structure. As a prior art, it is not described in detail in this case. In the device, a substrate 50 is fixedly provided on the upper surface of the training platform 200. 0, also includes: a dynamic force-amplifying stretching mechanism 600 for horizontally centering the plastic pipe fitting, and a circumferential cycle bending mechanism 700 for repeatedly bending the plastic pipe fitting during the stretching period. When in use, the dynamic force-amplifying stretching mechanism 600 is first used to synchronously clamp the two ends of the plastic pipe fitting, and continuously stretch and straighten it in opposite directions, and then the circumferential cycle bending mechanism 700 is used to bend a local area of ​​the plastic pipe fitting, and repeatedly rotate the bent part along a circular trajectory. During this period, the plastic pipe fitting as a whole will not rotate due to being clamped, so a multi-directional coupled composite motion state is formed at both ends of the bent part of the plastic pipe fitting, and because the direction of the applied force is not a linear direction, that is, the force directions at both ends of the bent part of the plastic pipe fitting show the variable characteristics of a non-fixed axis, so the two ends of the bent part of the plastic pipe fitting can be bent in multiple dimensions, and the cycle is repeated until both ends are completely broken.

[0032] Specifically, the dynamic force-enhancing stretching mechanism 600 includes two sleeve seats 601 symmetrically mounted on both sides of the middle of the upper surface of the base plate 500, a conical sleeve 602 is fixedly arranged inside the sleeve seat 601, the large ends of the two conical sleeves 602 are arranged opposite each other, and a clamping member for clamping the plastic pipe is arranged in the middle of the conical sleeve 602. The dynamic force-enhancing stretching mechanism 600 also includes a reverse screw 608 rotatably mounted on the middle of the base plate 500 through a bearing, and two traction plates 607 symmetrically arranged on both sides of the outer surface of the reverse screw 608, which are used to push and pull the clamping member so that the clamping member can clamp and release the plastic pipe, and a screw motor 609, which is used to drive the reverse screw 608, and the outer end of the reverse screw 608 It is connected to the output end of the screw motor 609 through a coupling.

The equiangular fork block 604 is connected to the traction plate 607, and one end of the chuck linkage arm 610 rotates with the equiangular fork block 604 through the arm shaft 611 The clamping arm 610 is provided with a fan-shaped tightening clamp 603 fixedly provided in the middle of the other end of the clamp linkage arm 610 for directly grasping the plastic pipe fitting. Torsion springs 612 for opening the clamp linkage arm 610 are wound on both sides of the outer surface of the arm shaft 611. The arm shaft 611 is connected to the clamp linkage arm 610, and the two rotate synchronously. The two ends of the torsion spring 612 are respectively connected to the equiangular fork block 604 and the arm shaft 611. The three corners of the equiangular fork block 604 are fixedly provided with positioning sleeve ears 613. The bottom of the fan-shaped tightening clamp 603 is provided with friction teeth 615 for increasing the friction at the joint when grasping the plastic pipe fitting and reducing the possibility of slipping. The middle of the upper surface of the fan-shaped tightening clamp 603 is fixedly provided with a roller seat 614. A pressure roller 616 is installed on the inner wall of the top of the wheel seat 614, and the pressure roller 616 is set to roll with the tapered sleeve 602. The small end of the tapered sleeve 602 and each positioning sleeve ear 613 are fixedly provided with a sleeve ear guide rod 606. The positioning sleeve ear 613 is slidably sleeved on the outer surface of the sleeve ear guide rod 606. The positioning sleeve ear 613 and the sleeve ear guide rod 606 are elastically arranged by the return spring 605. When in use, the screw motor 609 is first started to drive the reverse screw 608 to reverse, so that the two traction plates 607 respectively drive the two clamping parts away from each other. During this period, the two clamping parts will synchronously clamp the plastic pipe fittings under the action of the two tapered sleeves 602, and as the distance between the two increases, the plastic pipe fittings are stretched and straightened. It is worth noting thatA guide slot for mounting the reverse screw 608 is provided through the middle of the upper surface of the base plate 500, and both traction plates 607 slide along the track of the guide slot. The guide slot provides guidance for the two traction plates 607, preventing them from tilting during the pushing and pulling of the clamping member.

[0033] Specifically, the circumferential cyclic bending mechanism 700 includes an annular base 701 fixedly mounted on the middle of the upper surface of the base plate 500 and located between the two sleeve seats 601. The position of the annular base 701 is set to the position of the plastic pipe to be bent. The middle of both ends of the annular base 701 is fixedly provided with a side ring 702. The position of the side ring 702 is set to the position of the plastic pipe to be bent and broken. The middle of the annular base 701 is provided with a shaping frame 708 for bending and shaping the plastic pipe. The shaping frame 708 is composed of two parallel connecting plates and two parallel threaded rods spliced ​​end to end. The middle of the shaping frame 708 is provided with an adjusting outer wheel 704. The adjusting outer wheel The interior of 704 is provided with a contact inner wheel 703 which is rotated by a bearing and is used to directly contact the outer surface of the plastic pipe fitting and cooperate with the position movement of the adjustment outer wheel 704 to apply pressure to the plastic pipe fitting inserted in this part to make it bend. The two ends of the adjustment outer wheel 704 are respectively slidably provided on the outer surfaces of the two threaded rods of the shaping assembly frame 708. Both sides of the outer surfaces of the two threaded rods of the shaping assembly frame 708 are provided with fastening nuts 705 for fixing the position of the adjustment outer wheel 704 and the contact inner wheel 703. The adjustment outer wheel 704 is provided between the two fastening nuts 705. A gasket is provided on the outer surface of the fastening nut 705 and facing one end of the adjustment outer wheel 704, and the gasket slides The movable sleeve is arranged on the outer surface of the threaded rod of the shaping assembly frame 708. When in use, the outer adjustment wheel 704 and the contact inner wheel 703 are first slid along the threaded rod trajectory of the shaping assembly frame 708 to adjust the position so that the outer adjustment wheel 704 and the contact inner wheel 703 deviate from the center position of the annular base 701. During this period, the plastic pipe fittings inserted into the inner contact wheel 703 will be bent, and then the fastening nut 705 is used to lock the outer adjustment wheel 704 and the contact inner wheel 703 to shape the plastic pipe fittings. The middle part of the inner surface of the annular base 701 is rotated to provide a large gear ring 709 for driving the shaping assembly frame 708. The two connecting plates of the shaping assembly frame 708 are It is connected to the large ring gear 709, so that the large ring gear 709 can drive the shaped assembly frame 708 to rotate synchronously as a whole. Both sides of the inner surface of the annular base 701 are fixed with multiple ring gear interception blocks 710 arranged in a ring shape with equal spacing. The large ring gear 709 is set between the ring gear interception blocks 710 on both sides to prevent the large ring gear 709 from falling off. The large ring gear 709 and the ring gear interception blocks 710 rotate relative to each other. The top of the annular base 701 is rotatably installed with a small gear 706 through a bearing. The small gear 706 is meshed with the large ring gear 709. The outer end of the small gear 706 is connected and assembled with the output end of the external gear motor 707 through a coupling. The gear motor 707 is a servo motor.

[0034] Specifically, the side ring 702 is symmetrically provided with two pressing parts along the two ends of the diameter, and both are used to press the bending part of the plastic pipe fitting. An infrared emitting module 713 is installed on the outer surface of the side ring 702 and at the position of one of the pressing parts, and an infrared receiving module 714 is installed on the outer surface of the side ring 702 and at the position of the other pressing part. The positions of the infrared emitting module 713 and the infrared receiving module 714 correspond to each other. Before the bending part of the plastic pipe fitting is broken, the infrared signal emitted by the infrared emitting module 713 is blocked by the plastic pipe fitting. After the bending part of the plastic pipe fitting is broken, the infrared signal is blocked by the infrared emitting module 713. The infrared signal emitted by the infrared transmitting module 713 can be received by the infrared receiving module 714, wherein the pressing member is composed of an externally threaded hollow cylinder 717, an internally threaded hollow cylinder 715 and a flexible pressing ring 716. The externally threaded hollow cylinder 717 is connected to the side ring 702, and the internally threaded hollow cylinder 715 is arranged on the outer surface of the externally threaded hollow cylinder 717 through thread engagement. The flexible pressing ring 716 is fixedly arranged in the middle of the bottom end of the internally threaded hollow cylinder 715, and is used to position the compressed plastic pipe fittings to prevent the plastic pipe fittings from running off. The circumferential cyclic bending mechanism 700 also includes a large gear ring 709 for positioning the large gear ring 709. The counting unit counts the number of rotations of the large gear ring 709, and the counting unit includes a reflective mark 712 provided on the inner wall of one end of the large gear ring 709, and a reflective photoelectric sensor 711 installed on the upper surface of the substrate 500 and close to the large gear ring 709, and a motor emergency stop module for emergency stopping the gear motor 707 and the screw motor 609, and also includes a central processing unit and an external terminal device. The reflective photoelectric sensor 711 corresponds to the reflective mark 712 and the distance is sufficient. The infrared transmitting module 713, the infrared receiving module 714, the reflective photoelectric sensor 711, the gear motor 707, the screw motor 609, the motor emergency stop module, and the central processing unit are electrically connected. When in use, when the two ends of the bending part of the plastic pipe are pulled apart, the infrared signal emitted by the infrared transmitting module 713 can be received by the infrared receiving module 714. At this time, the signal is given to the motor emergency stop module, and the gear motor 707 and the screw motor 609 are emergency stopped. At this time, the reflective photoelectric sensor 711, the reflective mark 712 and the external terminal device can be used to determine the number of turns that the plastic pipe can withstand under multi-dimensional bending conditions, thereby accurately determining the fatigue resistance of the plastic pipe.

[0035] The working principle of the present invention is as follows: the screw motor 609 is started to drive the reverse screw 608 to rotate forward, and the two traction plates 607 are driven to move toward each other along the guide groove of the base plate 500, and the traction plate 607 pushes the equiangular fork block 604 to move axially in the conical sleeve 602. At this time, the ear guide rod 606 cooperates with the positioning ear 613 to guide, and the pressure roller 616 rolls along the inner wall of the conical sleeve 602, so that the three chuck linkage arms 610 are opened outward around the arm shaft 611 under the action of the torsion spring 612. Then, the screw motor 609 is started to drive the reverse screw 608 to reverse, and the two traction plates 607 move in the opposite direction. The three chuck linkage arms 610 are retracted inward, driving the fan-shaped tightening chuck 603 to clamp the pipe fitting, and the friction tooth pattern 615 increases the contact friction. As the traction plates 607 at both ends continue to separate, the pipe fitting is stretched horizontally and straightened. After that, the screw motor 609 is started to drive the reverse screw 608 to reverse, and the two traction plates 607 move in the opposite direction. The three chuck linkage arms 610 are retracted inward, driving the fan-shaped tightening chuck 603 to clamp the pipe fitting, and the friction tooth pattern 615 increases the contact friction. As the traction plates 607 at both ends continue to separate, the pipe fitting is stretched horizontally and straightened. The gear motor 707 uses the small gear 706 to drive the large ring gear 709 to rotate, and the shaping assembly frame 708 rotates synchronously with the large ring gear 709. The outer wheel 704 is adjusted to fix the eccentric position by tightening the nut 705, and the inner wheel 703 is contacted to apply radial pressure to the pipe to bend it into shape. During the rotation process, the clamping parts at both ends of the side ring 702 keep the end of the pipe fixed through the flexible pressing ring 716. When the bent part of the pipe is fatigued and fractured, the infrared transmitting module 713 signal is received by the infrared receiving module 714, triggering the motor emergency stop module to stop the screw motor 609 and the gear motor 707. At the same time, the reflective photoelectric sensor 711 counts the number of rotations of the large ring gear 709 through the reflective mark 712. Finally, the central processor transmits the anti-fatigue data to the external terminal device for display. Finally, AI is used to analyze the data to help students make judgments.
