[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Figure 1 It shows a schematic diagram of the structure of the gearbox disassembly and assembly flip teaching platform in an embodiment of the present invention. Figure 2 The exploded diagram of the gear transmission mechanism in the embodiment of the present invention is shown. Figure 3 A schematic diagram of the transmission assembly and reversal teaching platform structure from another perspective in an embodiment of the present invention is shown. The transmission assembly and reversal teaching platform comprises a base 1 and a support frame 2. The support frame 2 is disposed on one side of the base 1 and is arranged perpendicular to the base 1. Positioning the support frame 2 on one side of the base 1 allows sufficient space above the base 1 to flip the transmission, thereby adjusting its position.

[0036] Specifically, a rotating member 4 is provided on the support frame 2, one end of the rotating member 4 is provided in the support frame 2, and a clamping mounting seat 43 is provided on the other end of the rotating member 4. The clamping mounting seat 43 is used to clamp the gearbox. A plurality of matching holes are provided on the clamping mounting seat 43, and a locking bolt is provided in any of the matching holes. The locking bolt is used to fix the gearbox to improve the stability of the connection structure between the mounting seat and the gearbox.

[0037] Furthermore, the clamping mount 43 is a rectangular plate-like structure, and several of the matching holes are evenly distributed at the corner positions of the clamping mount 43, and the locking bolts correspond to the threaded connection holes on the gearbox, so that the gearbox can be locked on the clamping mount 43 by the locking bolts.

[0038] Specifically, Figure 4 Schematic diagram of the internal structure of the support frame 2 in an embodiment of the present invention is shown. Figure 5 A schematic diagram of the disconnected state of the gear transmission mechanism in an embodiment of the present invention is shown, wherein the rotating member 4 includes a rotating base 42 and a rotating shaft 41, wherein the rotating base 42 is arranged inside the support frame 2, and an inner wall of the support frame 2 is provided with a mounting groove, one end of the rotating base 42 is arranged in the mounting groove, and a mounting portion is provided on one end of the rotating base 42, and the rotating shaft 41 is plugged and fixed to the mounting portion. When the rotating base 42 rotates, the rotating shaft 41 can rotate under the drive of the rotating base 42.

[0039] Furthermore, the rotating member 4 also includes a connecting seat 411, which is sleeved on the rotating shaft 41. The connecting seat 411 is used to connect the rotating shaft 41 and the rotating base 42. The rotating base 42 is provided with a recessed portion, and the connecting seat 411 can be embedded in the recessed portion of the rotating base 42. The connecting seat 411 can improve the stability of the connection structure between the rotating shaft 41 and the rotating connecting base 1, and at the same time improve the rigidity of the rotating shaft 41, thereby improving the stability of the rotating shaft 41 driving the gearbox to rotate.

[0040] Furthermore, the mounting portion on the rotating base 42 can be an adjustable mounting portion, that is, the rotating base 42 can adjust the matching size of the mounting portion according to the actual size of the rotating shaft 41 to improve the versatility of the rotating base 42 and facilitate the maintenance and replacement of the rotating shaft 41 and the rotating base 42.

[0041] Specifically, a gear transmission mechanism is provided in the support frame 2, and the gear transmission mechanism includes a driving gear 6, a driven gear 5 and a movable connecting member 7. The driving gear 6 can be connected to the driven gear 5 based on the movable connecting member 7, thereby realizing gear transmission. The other end of the rotating member 4 is inserted into the driven gear 5, and a turntable 63 is provided on the support frame 2. A connecting shaft 62 is provided on the turntable 63, and one end of the connecting shaft 62 is inserted into the driving gear 6.

[0042] Furthermore, an axis connector 61 is also provided on the connecting shaft 62. The connecting shaft 62 can be connected to the inner wall of one side of the support frame 2 based on the axis connector 61. The connecting shaft 62 can rotate relatively in the axis connector 61, so that the teaching staff can rotate the turntable 63 to adjust the angle of the gearbox.

[0043] Specifically, the other end of the rotating base 42 is connected to the driven gear 5, and a connecting rod is provided at the rotation center of the driven gear 5. The connecting rod is inserted into the other end of the rotating base 42, and the rotating base 42 and the connecting rod can be interference fit, thereby improving the connection stability between the rotating base 42 and the driven gear 5, and ensuring the stability of power transmission between the rotating base 42 and the driven gear 5.

[0044] Specifically, the movable connecting member 7 includes a first gear 71, a second gear 72 and a transmission shaft 73. The first gear 71 and the second gear 72 are arranged on the transmission shaft 73, and the first gear 71 and the second gear 72 are coaxially arranged. The first gear 71 is engaged with the driving gear 6, and the second gear 72 is engaged with the driven gear 5. The operator drives the driving gear 6 to rotate by rotating the turntable 63, and drives the second gear 72 on the transmission shaft 73 to rotate through the first gear 71, thereby driving the driven gear 5 to rotate through the second gear 72, so that the clamping mount 43 can rotate.

[0045] Furthermore, the first gear 71 and the driving gear 6 may be staggered, and the second gear 72 and the driven gear 5 may be staggered, that is, the movable connecting member 7 is disconnected from the driving gear 6 and the driven gear 5.

[0046] Furthermore, the first gear 71 and the second gear 72 form a linkage gear structure, and the driving gear 6 can drive the second gear 72 to rotate by driving the first gear 71 to rotate. By setting the linkage gear, the transmission connection between the driving gear 6 and the driven gear 5 is achieved, and the transmission structure stability between the driving gear 6 and the driven gear 5 can be improved.

[0047] Specifically, the driving gear 6 and the second gear 72 are small-sized gears, and the driven gear 5 and the first gear 71 are large-sized gears. By setting the first gear 71 and the second gear 72 to realize transmission between the driving gear 6 and the driven gear 5, the transmission efficiency between the driving gear 6 and the driven gear 5 can be improved, and the transmission torque required for the driving gear 6 and the driven gear 5 can be reduced, so that the operator can save more effort when turning the turntable 63.

[0048] Specifically, the transmission ratio between the driving gear 6 and the first gear 71 is n1, the transmission ratio between the driven gear 5 and the second gear 72 is n2, and the transmission ratio between the driving gear 6 and the driven gear 5 is n1*n2. That is, by adjusting the transmission ratio between the driving gear 6 and the first gear 71 and the transmission ratio between the driven gear 5 and the second gear 72, the transmission ratio between the driving gear 6 and the driven gear 5 can be adjusted, thereby improving the accuracy of the turntable 63 in adjusting the rotation angle of the gearbox.

[0049] Furthermore, in this embodiment, the transmission ratio n1 between the driving gear 6 and the first gear 71 is 1:4, the transmission ratio between the second gear 72 and the driven gear 5 is 1:2, and the transmission ratio between the driving gear 6 and the driven gear 5 is n1*n2, that is, the transmission ratio between the driving gear 6 and the driven gear 5 is 1:8. The driving gear 6 rotates one circle, which can drive the driven gear 5 to rotate 45°, thereby driving the gearbox on the clamping mount 43 to rotate 45°. By adjusting the transmission ratio between the driving gear 6, the driven gear 5 and the movable connecting member 7, the precise angle control of the clamping mount 43 can be achieved, which facilitates the flipping and disassembly and teaching of the gearbox.

[0050] Furthermore, the turntable 63 may be provided with a rotation scale, and the turntable 63 may be marked with a rotation scale according to the transmission ratio of the gear transmission mechanism, so that teaching staff can adjust the rotation angle of the clamping mount 43 through the turntable 63 .

[0051] Furthermore, the working principle of the gear transmission mechanism is as follows: the operator manually rotates the turntable 63, and the turntable 63 drives the driving gear 6 on the connecting shaft 62 to rotate, and the driving gear 6 drives the meshing first gear 71 to rotate, thereby driving the second gear 72 on the transmission shaft 73 to rotate, and the second gear 72 drives the mutually meshing driven gears 5 to rotate, thereby driving the clamping mounting seat 43 on the rotating member 4 to rotate. The gear transmission mechanism performs gear transmission by driving the large gear with the small gear, which can reduce the driving force required for the operator to drive the clamping mounting seat 43, thereby improving the convenience of adjusting the clamping mounting seat 43 and reducing the labor intensity of the operator.

[0052] Further, Figure 6 The embodiment of the present invention is shown in FIG. Figure 4 An enlarged schematic diagram of the structure at point a shows that a matching groove 22 is provided in the support frame 2, and one end of the transmission shaft 73 is inserted into the matching groove 22. The transmission shaft 73 and the notch of the matching groove 22 are clearance-fitted, so that the transmission shaft 73 can rotate relative to the matching groove 22 and telescopically move in the matching groove 22.

[0053] Furthermore, by inserting the transmission shaft 73 into the matching groove 22 , both ends of the movable connecting member 7 are arranged inside the side walls of the support frame 2 , thereby improving the structural stability of the movable connecting member 7 .

[0054] The gear 71 is engaged with the first gear 6 and the second gear 72 is engaged with the first gear 6. When the gear 71 is engaged with the first gear 6, the gear 72 is engaged with the first gear 6. When the gear 71 is engaged with the first gear 6, the gear 72 is engaged with the first gear 6. When the gear 71 is engaged with the first gear 6, the gear 72 is engaged with the first gear 6. When the gear 71 is engaged with the first gear 6, the gear 72 is engaged with the first gear 6. When the gear 71 is engaged with the first gear 6, the gear 72 is engaged with the first gear 6.

[0055] Furthermore, a groove structure is provided on the circumferential outer wall of the button handle 75 , which can improve the convenience for the operator to stretch and press the button handle 75 .

[0056] Furthermore, the transmission shaft 73 can rotate relative to the coupling 74 , that is, when the first gear 71 is engaged with the driving gear 6 and the second gear 72 is engaged with the driven gear 5 , the transmission shaft 73 can rotate under the action of the driving gear 6 .

[0057] Specifically, a magnetic plate 21 is provided on the inner wall of one side of the support frame 2. When the operator stretches the button handle 75, the movable connecting member 7 can be moved closer to the magnetic plate 21, so that the coupling 74 is fitted with the magnetic plate 21. The magnetic plate 21 cooperates with the metal sheet on the coupling 74, so that the movable connecting member 7 can be magnetically fitted with the magnetic plate 21, thereby improving the structural stability of the movable connecting member 7 in the stretched state.

[0058] Furthermore, the magnetic plate 21 has weak magnetism and can be magnetically coupled with the metal sheet on the coupling 74. By setting the magnetic plate 21 with weak magnetism, the stability of the switching state of the movable connecting member 7 can be improved, while avoiding excessive magnetism affecting the operating stability of the gear transmission structure within the support frame 2.

[0059] Specifically, Figure 7A schematic structural diagram of the electromagnetic locking mechanism in an embodiment of the present invention is shown, wherein a matching hole is provided on the inner side wall of the support frame 2, and one end of the rotating base 42 is provided in the matching hole, that is, the rotating member 4 is inserted into the inside of the support frame 2 based on the matching hole, and an electromagnetic locking mechanism is provided at the matching hole, and the electromagnetic locking mechanism includes a plurality of accommodating slots 33, and the plurality of accommodating slots 33 are evenly arranged on the matching hole along the circumferential direction. An electromagnetic locking block 31, a telescopic rod 34, a coil 35 and a spring 32 are provided in any of the accommodating slots 33, one end of the telescopic rod 34 is fixed to the bottom of the accommodating slot 33, and the other end of the telescopic rod 34 is connected to the electromagnetic locking block 31, the coil 35 is provided on the inner wall of the accommodating slot 33, and the electromagnetic telescopic block is located in the coil 35. When the coil 35 is energized, the electromagnetic locking block 31 moves toward the notch direction of the accommodating slot 33 under the action of the electromagnetic field of the coil 35.

[0060] Specifically, one end of the spring 32 is fixed to the bottom end of the accommodating groove 33, and the other end of the spring 32 is fixed to the electromagnetic locking block 31. When the electromagnetic locking block 31 moves under the action of the coil 35, the spring 32 is stretched accordingly. When the coil 35 is in an off-circuit state, the electromagnetic locking block 31 can be elastically reset based on the spring 32.

[0061] Furthermore, the telescopic rod 34 is used to improve the telescopic movement of the electromagnetic locking block 31. The movable rod inside the telescopic rod 34 and the telescopic rod body 34 have a preset friction force, which can generate resistance when the telescopic rod 34 performs telescopic movement. When the electromagnetic locking block 31 moves outward based on the magnetic field of the coil 35, the movement rate of the electromagnetic locking block 31 can be reduced, and the movement impact force of the electromagnetic locking block 31 can be reduced, thereby improving the movement safety of the electromagnetic locking block 31; when the spring 32 drives the electromagnetic locking block 31 to perform elastic reset, the telescopic rod 34 can serve as a damper for the reset of the spring 32, offsetting the elastic force of the spring 32 when the spring 32 resets, thereby avoiding vibration of the electromagnetic locking block 31, which can effectively improve the movement stability of the electromagnetic locking block 31.

[0062] Furthermore, when the rotating member 4 rotates, a preset interval is maintained between any of the accommodating grooves 33 and the rotating member 4 , and the electromagnetic locking block 31 is disposed in the accommodating groove 33 , thereby preventing the electromagnetic locking block 31 from interfering with the rotation of the rotating member 4 .

[0063] Specifically, Figure 8A schematic diagram of the internal circuit connection structure in an embodiment of the present invention is shown. The electromagnetic locking mechanism also includes a power supply device 8 and an internal circuit. The power supply device 8 and several coils 35 are connected to the internal circuit. The internal circuit can provide electrical energy to the coils 35. Any of the electromagnetic locking blocks 31 is an electromagnet. When the internal circuit is connected, the coil 35 connects to the electric magnetic field of the power supply device 8. The electromagnetic locking block 31 generates magnetism in the electric field of the internal circuit. Under the action of the electromagnetic field, the electromagnet moves toward the notch of the receiving slot 33, so that the other end of the electromagnetic locking block 31 extends from the notch of the receiving slot 33 outside the receiving slot 33. The electromagnetic locking block 31 can be attached to the rotating base 42 of the rotating member 4 based on its own magnetism. The rotating base 42 is locked and fixed by multiple electromagnetic locking blocks 31, thereby preventing the rotating member 4 from rotating. This can prevent the gearbox from rotating during the teaching process of clamping and disassembling the gearbox, improve the stability of the gearbox clamping and disassembly, and thus improve the teaching effect of the gearbox.

[0064] Furthermore, the electromagnetic locking block 31 is clamped in the accommodating groove 33, and the inner wall of the accommodating groove 33 fits tightly with the electromagnetic locking block 31, which can increase the friction between the accommodating groove 33 and the electromagnetic locking block 31, thereby preventing the electromagnetic locking block 31 from extending outside the accommodating groove 33 due to its own gravity or external vibration when the internal circuit is disconnected, thereby reducing the risk of the electromagnetic locking block 31 affecting the rotation of the rotating part 4.

[0065] Specifically, the power supply device 8 is arranged on the base 1 and is located on the side wall of the bottom of the support frame 2. The internal circuit is arranged inside the inner wall on the other side of the support frame 2. The power supply device 8 is electrically connected to the electromagnetic locking block 31 based on the internal circuit.

[0066] Furthermore, by arranging the power supply device 8 outside the support frame 2, it is convenient to supplement the power supply device 8 of the internal circuit, and the convenience of repairing and replacing the power supply device 8 of the internal circuit of the support frame 2 is improved.

[0067] Specifically, a compression spring 24 and a metal connecting block 23 are provided in the mating groove 22 on the inner wall of the support frame 2, one end of the compression spring 24 is fixed to the bottom end of the mating groove 22, and the other end of the compression spring 24 is provided on the metal connecting block 23. The internal circuit passes through the mating groove 22, and the internal circuit forms a notch based on the mating groove 22. The internal circuit is in a disconnected state based on the notch, that is, the electromagnetic locking mechanism is in an open circuit state.

[0068] Furthermore, the wires at one end of the notch of the internal circuit are exposed on the inner wall of one side of the mating groove 22, and the wires at the other end of the notch are exposed on the inner wall of the other side of the mating groove 22. The wires of the internal circuit exposed in the mating groove 22 form an internal circuit connection terminal 25, and the metal connection block 23 is in contact with the inner wall of the mating groove 22. When the metal connection block 23 contacts the internal circuit connection terminal 25, the internal circuit can be connected based on the metal connection block 23, that is, the electromagnetic locking mechanism can enter the working state based on the metal connection block 23.

[0069] Specifically, one end of the transmission shaft 73 is inserted into the matching groove 22, and one end of the transmission shaft 73 is connected to the metal connecting block 23. When the button handle 75 is in a pressed state, that is, the driving gear 6 and the first gear 71 are engaged, and the driven gear 5 and the second gear 72 are engaged, the metal connecting block 23 stays at a position near the bottom end in the matching groove 22 under the pressing action of the transmission shaft 73, so that the metal connecting block 23 is staggered with the internal circuit, the internal circuit is in an open circuit state, the electromagnetic locking mechanism is in a non-working state, and the rotating part 4 can rotate driven by the turntable 63, thereby facilitating the adjustment of the state and posture of the gearbox on the clamping mounting seat 43.

[0070] Furthermore, when the button handle 75 is in a stretched state, that is, the driving gear 6 and the first gear 71, the driven gear 5 and the second gear 72 are disengaged, the coupling 74 is magnetically attached to the magnetic plate 21, and one end of the transmission shaft 73 is inserted into the notch position of the matching groove 22. The metal connecting block 23 moves toward the notch direction of the matching groove 22 under the action of the compression spring 24, and stops at a position near the notch in the matching groove 22 under the action of the compression spring 24 and the transmission shaft 73. The metal connecting block 23 is connected to the internal circuit, thereby connecting the internal circuit, so that the electromagnetic locking mechanism is in an energized working state. The electromagnetic locking block 31 extends out of the accommodating groove 33 based on electromagnetic properties, and is magnetically attached to the rotating part 4, thereby locking the rotating part 4 to prevent the rotating part 4 from rotating due to external interference, thereby achieving the fixed state and posture of the gearbox.

[0071] Furthermore, an insulating layer is coated on one end of the transmission shaft 73, and the insulating layer is used to isolate the transmission shaft 73 and the metal connecting block 23, thereby preventing the transmission shaft 73 and the metal connecting block 23 from being electrically connected, and preventing leakage of the internal circuit of the support frame 2, thereby ensuring the safety of the internal circuit of the support frame 2.

[0072] Specifically, a pad is provided on the base 1, and the pad is laid on the top surface of the base 1. The pad is made of a polymer elastic material and has good impact resistance and shock absorption performance. It can prevent the gearbox from causing impact damage to the base 1 or the ground when it accidentally falls, and effectively improve the safety of the gearbox disassembly and assembly flipping teaching platform.

[0073] Furthermore, a moving component may be provided at the bottom of the base 1, and the moving component includes a plurality of moving wheels, which are evenly distributed around the bottom of the base 1, so that teaching personnel can transfer and adjust the position of the gearbox disassembly and flip teaching platform.

[0074] Furthermore, the moving wheel may be a universal wheel so that teaching staff can adjust the moving direction of the teaching platform.

[0075] An embodiment of the present invention provides a transmission assembly and disassembly flipping teaching platform. The platform utilizes a gear transmission to drive the rotation of a clamping mount 43. A small gear drives a large gear, which in turn rotates in conjunction with a movable connector 7 to drive the rotation of the clamping mount 43. This improves the structural stability of the gear transmission mechanism, while also making rotational adjustments more convenient for operators and reducing labor intensity. Adjusting the connection state of the movable connector 7 can disconnect the transmission connection of the gear transmission mechanism, fix the position of the clamping mount 43, and improve the stability of the transmission assembly and disassembly teaching platform, thereby enhancing the teaching effect.
