Description

Technical Field

[0001] This utility model belongs to the technical field of motor winding safety simulation device, and in particular relates to a pure pneumatic mechanical injury training device. Background Technology

[0002] An electric motor generates driving torque and serves as a power source for electrical appliances or various machines. Its main function is to convert electrical energy into mechanical energy. The coil of the motor is an important component of the motor, and the quality of the coil affects the power of the motor. In the teaching process, winding training devices are needed to demonstrate to students.

[0003] Existing motor winding training devices use cylinders as the driving mechanism to move the stator core. However, during the teaching process, there is a risk of the cylinder malfunctioning and injuring the instructor when the instructor needs to remove the stator core during explanation, leading to safety accidents. Therefore, there is an urgent need for a purely pneumatic mechanical injury training device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a purely pneumatic mechanical injury training device to solve the problem mentioned in the background art, where, during the teaching process, the cylinder malfunctions and injures the instructor when the instructor needs to remove the stator core during explanation, leading to a safety accident.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A purely pneumatic mechanical injury training device includes a frame, a protective door installed on one side wall of the frame, and a pneumatic assembly installed inside the frame. The pneumatic assembly includes:

[0007] An air compressor, fixed to one side wall of the frame, is used to provide compressed gas;

[0008] The gas pipeline is connected to the air compressor and can transmit the compressed gas generated by the air compressor. It also has two sets of circuits: an intake circuit and an exhaust circuit.

[0009] The cylinder, connected to the gas pipeline, serves as an actuator and can drive the robotic arm to lift and lower via a linkage plate.

[0010] A switching valve, installed on the gas pipeline, is used to control the switching of the gas path, thereby enabling the switching between manual and automatic control of the cylinder.

[0011] A manual control valve is installed on the manual control gas line of the gas pipeline, which can manually control the operation of the cylinder.

[0012] The stroke limit valve is installed on the outside of the piston rod of the cylinder, which can realize automatic control of the cylinder stroke, automatic reversing, and automatic reciprocating action.

[0013] By adopting the above technical solution, during the teaching process, the switching valve enables the cylinder to switch between manual and automatic modes. When switched to manual control, the cylinder can be raised and lowered by the manual control electric control. When switched to automatic control, the cylinder can be automatically reversed by the stroke limit valve, thereby enabling it to automatically reciprocate.

[0014] Furthermore, the pneumatic assembly also includes:

[0015] A micro valve is installed on the main gas line of the gas pipeline to control the opening and closing of the main gas line. When the protective door is opened, it can quickly cut off the main gas supply.

[0016] The roller-type mechanical reversing valve is installed on the air intake and exhaust circuits of the gas pipeline and is located at the position of the protective door. When the protective door is opened, the roller-type mechanical reversing valve is triggered to operate, thereby causing the cylinder to stop quickly due to the closure of the exhaust circuit. This effectively prevents the robotic arm from descending due to its own weight and prevents potential safety hazards.

[0017] By adopting the above technical solution, when manual teaching is required, the main air circuit is controlled by the micro-motion valve during the opening of the protective door, quickly cutting off the main air supply. At the same time, the roller-type mechanical reversing valve is triggered, which causes the cylinder to stop quickly due to the closure of the exhaust circuit. This effectively prevents the robotic arm from falling due to its own weight, prevents safety hazards, and achieves dual protection.

[0018] Furthermore, a drive assembly is mounted on the top of the cylinder, the drive assembly comprising:

[0019] The screw is rotatably mounted between the inner walls of the frame;

[0020] Guide rods are welded between the inner walls of the frame;

[0021] The screw block is threadedly mounted on the screw and slidably connected to the guide rod;

[0022] A drive motor; as a drive source, it can drive the screw to rotate.

[0023] By adopting the above technical solution, the drive motor drives the screw to rotate, which in turn causes the screw block to move through the cylinder under the action of the thread and the guide rod, thereby realizing the transfer of the stator core through the mechanical arm.

[0024] Furthermore, a simulation component is also provided within the rack, the simulation component comprising:

[0025] A storage tank, mounted on the frame, stores the red liquid;

[0026] A linkage rod is fixed to one side wall of the linkage plate, with its other end located inside the liquid storage tank.

[0027] The guide pipe is fixed to the bottom of the liquid storage tank and can guide the red liquid when the linkage rod squeezes the liquid in the liquid storage tank.

[0028] By adopting the above technical solution, during the operation of the cylinder, the linkage rod drives the linkage rod to move downward, thereby causing it to squeeze the red liquid in the storage tank through the guide pipe.

[0029] Furthermore, the simulation component also includes:

[0030] A simulated human hand is installed inside the frame and connected to the flow guide pipe;

[0031] A nozzle, installed at the end of the flow tube, allows the red liquid to flow onto the mannequin's hand, thereby serving as a warning to instructors and students.

[0032] By adopting the above technical solution, the squeezed red liquid is sprayed through the nozzle onto the simulated person's hand, which can serve as a warning to teachers and students and improve the safety performance of the device.

[0033] Furthermore, an operation box is installed on one side wall of the frame, and the operating mechanisms of the switching valve, the micro valve, the manual control valve, and the stroke limit valve are all located on the operation box.

[0034] By adopting the above technical solution, the operation box can easily control each valve, thereby realizing the control of the gas pipeline.

[0035] Furthermore, a mold base is provided directly below the robotic arm, which can be used to place the nail core.

[0036] By adopting the above technical solution, the stator core is wound inside the mold base, and then demonstrated to the students.

[0037] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:

[0038] This utility model uses a set of simulated transfer manipulators, which rely on stroke limit valves to realize the main up and down movement of the cylinders. It requires no power supply and relies entirely on pneumatic switches. At the same time, each time the main movement is completed, the corresponding simulation components also selectively move to achieve the effect of safety education demonstration. In addition, during the manual teaching of opening the protective door, the main air supply is cut off by micro valves and roller-type mechanical reversing valves, and the safety factor is ensured by the access control switch circuit, which has a high performance.

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0049] like Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figure 7 As shown, a purely pneumatic mechanical injury training device includes a frame 1, with a protective door 2 installed on one side wall of the frame 1. A pneumatic assembly 5 is installed inside the frame 1. The pneumatic assembly 5 includes: an air compressor 501, fixed to one side wall of the frame 1, used to provide compressed gas; a gas pipeline 505, connected to the air compressor 501, which can transmit the compressed gas generated by the air compressor 501 and has both intake and exhaust circuits; a cylinder 502, connected to the gas pipeline 505, serving as an actuator, which can drive a robotic arm 504 to move up and down via a linkage plate 503; a switching valve 506, installed on the gas pipeline 505, used to control the switching of the gas path, realizing the switching between manual and automatic control of the cylinder 502; and a manual control valve 507, installed on the gas pipeline 505. In the manual control pneumatic circuit of cylinder 502, the operation of cylinder 502 can be manually controlled. The stroke limit valve 510, installed on the outside of the piston rod of cylinder 502, can automatically control the stroke of cylinder 502, realize automatic reversing, and realize automatic reciprocating motion. The micro valve 509, installed on the main pneumatic circuit of gas pipeline 505, is used to control the opening and closing of the main pneumatic circuit. When the protective door 2 is opened, it can quickly cut off the main pneumatic supply. The roller mechanical reversing valve 508 is installed on the air intake and exhaust circuit of gas pipeline 505 and located at the position of protective door 2. When protective door 2 is opened, the roller mechanical reversing valve 508 is triggered to act, so that cylinder 502 can stop quickly due to the closure of the exhaust circuit, effectively preventing the robot arm 504 from falling due to its own weight and preventing safety hazards.

[0050] The specific steps are as follows:

[0051] During the teaching process, the compressed gas generated by the air compressor 501 acts on the cylinder 502, which drives the robotic arm 504 to move and grasp the stator core. The switching valve 506 enables the cylinder 502 to switch between manual and automatic operation. When switched to manual control, the cylinder 502 can be raised and lowered manually or electrically. When switched to automatic control, the cylinder 502 can be automatically reversed through the stroke limit valve 510, thus enabling it to move back and forth automatically. When manual teaching is required, the micro valve 509 controls the opening and closing of the main air circuit during the opening of the protective door 2, quickly cutting off the main air supply. At the same time, the roller-type mechanical reversing valve 508 is triggered, which causes the cylinder 502 to stop quickly due to the closure of the exhaust circuit. This effectively prevents the robotic arm 504 from descending due to its own weight, preventing safety hazards and achieving dual protection.

[0052] like Figures 1-3 As shown, in one embodiment, a drive assembly 3 is installed at the top of the cylinder 502. The drive assembly 3 includes: a screw 302, which is rotatably installed between the inner walls of the frame 1; a guide rod 304, which is welded between the inner walls of the frame 1; a screw block 303, which is threadedly installed on the screw 302 and slidably connected to the guide rod 304; and a drive motor 301, which serves as a drive source and can drive the screw 302 to rotate.

[0053] The specific steps are as follows:

[0054] The drive motor 301 drives the screw 302 to rotate, which in turn causes the screw block 303 to move through the cylinder 502 via the thread and guide rod 304, thereby enabling the mechanical arm 504 to move, and thus the mechanical arm 504 to transfer the stator core.

[0055] like Figure 1 , Figure 2 , Figure 3 as well as Figure 6 As shown, in one embodiment, the frame 1 is further equipped with a simulation component 7, which includes: a liquid storage tank 701, which is installed on the frame 1 and stores red liquid; a linkage rod 703, which is fixed on one side wall of the linkage plate 503 and has its other end located inside the liquid storage tank 701; a guide pipe 702, which is fixed to the bottom of the liquid storage tank 701 and can guide the red liquid when the linkage rod 703 squeezes the liquid in the liquid storage tank 701; a simulated hand 704, which is installed in the frame 1 and connected to the guide pipe 702; and a nozzle 705, which is installed at the end of the guide pipe 702 and can make the red liquid flow onto the simulated hand 704, thereby serving as a warning to teachers and students.

[0056] The specific steps are as follows:

[0057] During the operation of cylinder 502, linkage rod 703 moves downward, causing it to squeeze the red liquid in storage tank 701 through guide pipe 702. The squeezed red liquid is sprayed onto simulated hand 704 through nozzle 705, which can serve as a warning to instructors and students and improve the safety performance of the device.

[0058] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment: an operation box 4 is installed on one side wall of the frame 1. The operating mechanisms of the switching valve 506, micro valve 509, manual control valve 507 and stroke limit valve 510 are all located on the operation box 4. A mold base 6 is provided directly below the robot arm 504. The mold base 6 can be used to place the nail core.

[0059] The specific steps are as follows:

[0060] The control box 4 allows for easy control of various valves, thereby enabling control of the gas pipeline 505. The stator core is wound within the mold base 6, which is then demonstrated to the students.

[0061] In summary, the working principle of this purely pneumatic mechanical injury training device is as follows: When an external power source is connected, during the teaching process, the compressed gas generated by the air compressor 501 acts on the cylinder 502. The cylinder 502 drives the robotic arm 504 to move and grasp the stator core. Simultaneously, the drive motor 301 drives the screw 302 to rotate, thereby causing the screw block 303 to move through the cylinder 502 and the guide rod 304 under the action of the thread, thus achieving the transfer of the stator core. During the operation of the cylinder 502, the linkage rod 703 moves downward, thereby squeezing out the red liquid in the storage tank 701 through the guide pipe 702. The squeezed red liquid is sprayed out through the nozzle 705 onto the simulated hand. On 704, it can serve as a warning to instructors and students. At the same time, the switching valve 506 can switch between manual and automatic operation of cylinder 502. When switched to manual control, the cylinder 502 can be raised and lowered manually or electrically. When switched to automatic control, the cylinder 502 can be automatically reversed through the stroke limit valve 510, thus making it automatically reciprocate. When manual teaching is required, during the opening of the protective door 2, the micro valve 509 controls the opening and closing of the main air circuit, quickly cutting off the main air supply. At the same time, it triggers the action of the roller mechanical reversing valve 508, so that cylinder 502 can stop quickly due to the closure of the exhaust circuit. This effectively prevents the robot arm 504 from falling due to its own weight, prevents safety hazards, and achieves dual protection.

[0062] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
