[0002] The automotive alternator is an important component of the car and an important part of the automotive electrical system. Students majoring in automobiles, whether in secondary vocational schools, higher vocational schools, or undergraduate schools, all go from junior high school and high school, that is, non-vocational professional education, to vocational professional education. In the process of professional learning, they need to learn about automotive alternators. The automotive alternator is a perfect electromechanical product, involving the application of knowledge in many fields such as mechanical principles, tolerance matching, electromagnetic principles, electrical and electronic engineering, CAN or LIN communication, etc. Through in-depth analytical learning, a lot of knowledge verification and ability improvement can be obtained. It is the key and difficult point in the professional learning process. The current generator demonstration teaching mainly has the following problems: 1. The generator rotor bearing and the front and rear end cover bearing seat holes, the rotor shaft, and the rotor commutator copper ring and the rotor shaft use interference fit, all of which have a certain amount of interference, making disassembly and assembly very difficult. Pullers, presses and some auxiliary tools are usually required, and the whole process is scattered and messy; 2. Since the generator consists of a stator, rotor, brushes, slip rings, rectifiers, voltage regulators, bearings, end covers, and pulleys, each of which has its own technical requirements and working principles, special detection and measurement tools are required for detection and measurement. Some require the formulation of detection methods based on the working principles, and some require the design of experiments. Through experimental data and phenomena, analysis, judgment and verification are carried out, which has a certain degree of complexity and difficulty; 3. Since it is necessary to test whether the assembled generator is normal, it is necessary to use external force to drive the generator to rotate, and provide external excitation current, CAN or LIN control instructions, and monitor the speed, voltage, and current with simulated load at the same time. 4. Due to the large number of experimental supplies used in the teaching process, such as disassembly and assembly tools, testing tools, measuring tools, welding tools, disassembled parts and accessories, spare accessories, etc., it is difficult to select and store them, which is inconvenient for teaching.

[0043] The automotive alternator is an important component of the car and an important part of the automotive electrical system. Students majoring in automobiles, whether in secondary vocational schools, higher vocational schools, or undergraduate schools, all go from junior high school and high school, that is, non-vocational professional education, to vocational professional education. In the process of professional learning, they need to learn about automotive alternators. The automotive alternator is a perfect electromechanical product, involving the application of knowledge in many fields such as mechanical principles, tolerance matching, electromagnetic principles, electrical and electronic engineering, CAN or LIN communication, etc. Through in-depth analytical learning, a lot of knowledge verification and ability improvement can be obtained. It is the key and difficult point in the professional learning process. The current generator demonstration teaching mainly has the following problems: 1. The generator rotor bearing and the front and rear end cover bearing seat holes, the rotor shaft, and the rotor commutator copper ring and the rotor shaft use interference fit, all of which have a certain amount of interference, making disassembly and assembly very difficult. Pullers, presses and some auxiliary tools are usually required, and the whole process is scattered and messy; 2. Since the generator consists of a stator, rotor, brushes, slip rings, rectifiers, voltage regulators, bearings, end covers, and 32 belt wheels, each of which has its own technical requirements and working principles, special detection and measurement tools are required for detection and measurement. Some require the formulation of detection methods based on the working principles, and some require the design of experiments. Through experimental data and phenomena, analysis, judgment and verification are carried out, which has a certain degree of complexity and difficulty; 3. Since it is necessary to test whether the assembled generator is normal, it is necessary to use external force to drive the generator to rotate, and provide excitation current, CAN or LIN control instructions, and monitor the speed, voltage, and current with simulated load at the same time. 4. Due to the large number of experimental supplies used in the teaching process, such as disassembly and assembly tools, testing tools, measuring tools, welding tools, disassembled parts and accessories, spare accessories, etc., it is difficult to select and store them, which is inconvenient for teaching.

[0044] The utility model provides a comprehensive platform for disassembling, assembling, detecting and testing a generator to solve the above problems.

[0045] See also Figures 1 to 3, the direction description in this solution refers to the direction marking example in the attached drawing structure. In an embodiment of the present utility model, the disassembly and assembly teaching and detection teaching in the traditional automotive generator teaching process are concentrated on a comprehensive teaching platform structure. It has good integration in actual application and is more convenient for teaching. Specifically, the generator disassembly, detection, and test comprehensive platform includes a housing 1, a disassembly structure, a detection structure, and a test structure. The housing 1 structure includes an upper housing part 11 and a lower housing part 12. An operating table 121 is formed on the upper end surface of the lower housing part 12. The disassembly structure is arranged on the operating table 121. During actual use, first, the component structure of the generator is disassembled through the pulling and pressing assembly structure. Specifically, the interference fit components in the generator can be disassembled and assembled through the pulling and pressing assembly 5. For example, the generator rotor bearing and the rotor slip ring copper sleeve can be disassembled through the pulling and pressing assembly, or the bearing can be installed on the bearing seat of the generator. Through the operation of the pulling and pressing assembly, teaching can be carried out more intuitively, and the teaching content is also richer. During the teaching process, various tools required, such as sockets, ratchet wrenches, hammers, rubber hammers, screwdrivers, electric impact wrenches, hot air guns, cleaning agents, etc., can be placed in an orderly manner in the storage structure 4, with convenient storage and more convenient teaching.

[0046] After the internal components of the generator are disassembled by the above tools, the relevant components inside the generator can be detected through the detection structure. Specifically, the relevant detection devices are taken out from the storage structure 4. The relevant detection devices include but are not limited to current test elements and voltage test elements, etc. When in use, power can be obtained through the electrical connection structure on the upper housing part 11, and the relevant test data can also be displayed and stored through the all-in-one computer 111.

[0047] After the internal components of the generator are detected, the entire generator is assembled with the help of the pulling and pressing assembly structure, and then the overall working condition of the generator is tested. The test structure includes a fixing structure 2 and a driving system 3, mainly to test the stability of the voltage and current during the working process of the generator. During the actual test, first, the generator to be tested is fixed through the fixing structure 2, and then the driving system 3 drives the output end of the generator to be tested to rotate at different speeds, so as to test its stability under different working conditions. Among them, the test data can be imported into the all-in-one computer 111 through the electrical connection structure, and the working stability of the generator to be tested can be obtained through the comparison of relevant data.

[0048] In this embodiment, when disassembling and assembling the generator, a hydraulic jack 52 is used as the main driving component for pressing the bearing parts in and out. The hydraulic jack 52 is a conventional driving structure, and one end of it is usually provided with a manual lever structure 545 to drive the pressing part of the hydraulic jack 52 to move along its axis. The pressing part of the hydraulic jack 52 is usually set as a shaft structure. The above are common knowledge and will not be elaborated here. Among them, when disassembling the interference fit structure in the generator for teaching, first, use common tools to remove the screws on the generator and disassemble the generator. When it is necessary to remove interference fit parts such as the rotor bearing and the rotor slip ring copper sleeve of the generator, adjust the vertical height of the hydraulic jack 52 through the adjusting part, make the end of the pressing part of the hydraulic jack 52 abut against the axis of the rotor shaft, and at the same time hook the downward end of the claw part to the outer ring of the rotor bearing. Drive the pressing part of the hydraulic jack 52 to reciprocate in the vertical direction by pulling and pressing the lever structure 545 on the upper end of the hydraulic jack 52. At the same time, the end of the pressing part of the hydraulic jack 52 moves downward, so as to pull the bearing off the rotor shaft.

[0049] When it is necessary to remove the rotor bearing from the bearing seat hole of the generator end cover, at this time, support the end cover of the generator equipped with the bearing on the bottom plate 511 to an appropriate height with the support cylinder, remove the claw part from the adjusting part, use the adjusting part to adjust the pressing part of the hydraulic jack 52 above the end cover of the generator equipped with the bearing, use the sleeve part to abut against the outer ring of the bearing, drive the pressing part of the hydraulic jack 52 to reciprocate in the vertical direction through the lever structure 545, use the pressing part of the hydraulic jack 52 to press the sleeve part, and the sleeve part presses the outer ring of the bearing to press the bearing out of the bearing seat hole of the generator end cover.

[0050] When installing the bearing, the operation process is similar to the above actions. The hot air gun in the disassembly and assembly tool box in the storage structure 4 can also be used to take power from the electrical connection structure 112, heat the bearing seat hole of the end cover, and utilize the thermal expansion principle to make the bearing seat hole larger, so as to easily install the bearing. After installing the generator slip ring copper sleeve, weld the slip ring copper sleeve and the rotor coil, and use the soldering iron stored in the storage structure 4 for welding, also taking power from the electrical connection structure 112. Therefore, in this embodiment, the provided related structures enable students to complete the disassembly and installation of the generator by themselves through the above structures and related tools. In this process, the operation difficulty in the actual operation process can be simplified as much as possible, so that students can better remember the installation and disassembly process of the related structures of the generator.

[0051] Among them, the adjusting member includes a first screw rod 521 and an adjusting nut 531. The first screw rod 521 is set as a hollow structure, and its internal through hole is sleeved on the outside of the lower pressure part of the hydraulic jack 52, and its upward end is fixedly connected to the lower end of the hydraulic jack 52. When the adjusting nut 531 rotates at the circular hole 5121, because it is threadedly connected to the first screw rod 521, it can simultaneously drive the hydraulic jack 52 to adjust its position in the vertical direction. Corresponding to its adjustment process, the spring structure will produce different degrees of deformation.

[0052] The clamping member includes two clamping parts 53, and the upward ends of the two clamping parts 53 are respectively installed at multiple installation ears on the peripheral wall of the adjusting nut 531. It should be noted that a detachable installation structure is used between the two. For example, it is feasible to fix and install the clamping parts 53 by bolts, etc. Specifically, after the clamping parts 53 are installed, they are limited and fixed by limiting steel balls to prevent them from falling off due to force. When the installation structure formed by the bearing and the shaft is dismantled, the outer ring of the bearing is pulled by the multiple hooks 533 at the ends of the two clamping parts 53, and then the shaft end of the installation shaft is supported by the downward pressure part of the hydraulic jack 52, and the force is applied by the downward pressure part of the hydraulic jack 52 to separate the two assembly parts.

[0053] It is conceivable that the clamping claw portion 53 can be configured as a prefabricated part of various types, and the various types can be designed according to the various types of generators, wherein the thickness of the hook portion 533 can be set to different thicknesses according to the types of different generators. After the relevant prefabricated parts are manufactured, they can be installed and used according to the types of generators, and can be suitable for different disassembly situations.

[0054] After the generator is disassembled, its internal components can be inspected through the detection structure. Specifically, the computer-in-one machine 111 stores various types of generator working principle diagrams, experimental operation explanation video courseware, experimental instructions and other electronic experimental materials. The experimental operation explanation video courseware is explained by teachers with many years of teaching experience, and combined with on-site design experimental verification, the design process and design concept of the generator are reviewed. From abstract theory to specific parts, the combination of theory and practice is truly achieved. The experimental display and explanation process is filmed into a video, which is played on the computer-in-one machine 111 through the video courseware to guide students to test experiments and learn, creating a new experimental teaching and research model.

[0055] Therefore, during actual operation, corresponding materials can be found on the all-in-one computer 111 according to the type of the generator to be tested currently to assist in guiding the detection operation process of the internal components of the generator. Specifically, when detecting the internal components of the generator, first take out various test devices and materials (such as: multimeter, vernier caliper, soldering iron, solder, sandpaper, rosin and other tool consumables, and vulnerable parts and spare parts of the generator such as generator rectifier, generator voltage regulator, brush, slip ring copper sleeve, bearing, etc.) from the storage structure 4. The electrical connection structure includes communication signal terminals (power supply positive electrode, power supply negative electrode, charging display element, CANH, CANL, LIN), power supply interface, etc., which can provide power supply, control signals and monitoring data for the tests designed to detect components such as the stator, rotor, rectifier, voltage regulator, etc. inside the generator through the above structures.

[0056] After testing the relevant components inside the generator, assemble the relevant structures of the generator, and then prepare to conduct an experimental test on the overall performance of the generator through the test structure.

[0057] Before conducting an experimental test on the whole generator, it is necessary to fix it first. During actual operation, first place the generator on the V-shaped support block 22 on the receiving bottom plate 21, and conduct preliminary limit on it through the sinking groove of the V-shaped support block 22. Then rotate the second screw member 24 on the portal bracket 23 to drive the V-shaped pressing block 26 to move downward, and engage the V-shaped sinking groove of the V-shaped pressing block 26 with the peripheral wall of the generator. Then continue to rotate the second screw member 24 by tightening the handle 25 to make the V-shaped pressing block 26 provide sufficient downward pressure, so as to fix the generator between the V-shaped pressing block 26 and the V-shaped support block 22.

[0058] In order to further improve the installation and fixation effect of the generator, the thread direction of the second lead screw 24 is set to right-handed. There are two sections of mating left-handed threads between one end of the second lead screw 24 and the V-shaped pressing block 26. After rotating the second lead screw 24 to make the V-shaped pressing block 26 contact the outer wall of the generator, the V-shaped pressing block 26 remains stationary. Continuing to rotate the second lead screw 24, the two sections of left-handed threads between one end of the second lead screw 24 and the V-shaped pressing block 26 rotate relative to each other, causing the total length between the entire second lead screw 24 and the V-shaped pressing block 26 to have a tendency to increase. This further increases the force between the V-shaped pressing block 26 and the generator, thereby improving the fixation effect on the generator. Moreover, locking nuts 542 are provided between the second lead screw 24 and the gantry bracket 23, and between the second lead screw 24 and the V-shaped pressing block 26. After the generator is fully fixed, the locking nuts 542 can be used to enhance the fixation effect on the second lead screw 24 and the V-shaped pressing block 26, preventing the fixation effect of the second lead screw 24 and the V-shaped pressing block 26 from deteriorating due to vibrations generated during the generator test, thereby further enhancing the safety during the test process. When testing the generator, the belt 32 is sleeved between the input shaft of the generator and the output shaft of the three-phase motor 31, and the tension of the belt 32 is adjusted through the tensioning structure 33. When the three-phase motor 31 rotates, it can drive the generator to rotate synchronously. During the test, the test generator is connected to the circuit board structure to obtain the voltage and current conditions of the test generator under different rotational speed conditions.

[0059] Among them, the tensioning structure 33 has a movable mounting seat. The mounting seat moves along the front-back direction of the pressing portion on the lower housing portion 12, and can drive the tensioning wheel to adjust its position in the front-back direction, thereby adjusting the tension of the belt 32. The tensioning wheel structure is a common structure in the belt drive structure, and will not be elaborated here.

[0060] A corresponding three-phase motor variable frequency speed regulator 34 is also provided on the upper housing portion 11, which can adjust the actual rotational speed of the three-phase motor 31 through the three-phase motor variable frequency speed regulator 34, thereby applying different load rotational speeds to the generator.

[0061] The storage structure 4 includes a plurality of tool boxes provided on the lower housing portion 12. The plurality of tool boxes include a plurality of disassembly tool boxes 41, a plurality of detection instrument tool boxes 42, and a plurality of experimental wire harness tool boxes 43. The three different types of tool box structures are stacked vertically. During actual teaching, different utensils are stored in different types of tool boxes, and the names of the internal tools can be marked on the corresponding tool box structures, making it more convenient for storage and retrieval.

[0062] In this embodiment, the all-in-one computer 111 mainly includes a storage component and a transceiver component. The storage component pre-stores standard test data of various models of generators. During the actual test, the corresponding standard test data can be retrieved according to the model of the current generator as a reference value for the test. The transceiver component is connected to the circuit board structure. During the test, it can obtain the actual test data of the test generator, then transmit the relevant data to the storage component for collection, and can be displayed in real time through the all-in-one computer 111. And the all-in-one computer 111 is installed with CAN analyzer host computer software and stores CAN or LIN signal messages of generators of relevant vehicle models. When testing generators with CAN or LIN control, the host computer software is used to send CAN or LIN signal messages, which are sent to the generator through the LIN interface 75 or the platform panel CANL interface 76 and the platform panel CAN H interface 77 on the electrical connection structure to drive the generator to generate electricity. The USB interface 78 on the electrical connection structure is used to store the CAN or LIN signal messages of generators of relevant vehicle models read from the vehicle through the CAN analyzer in advance or the recorded experimental operation explanation video courseware into the all-in-one computer 111 through it.
