[0021] By placing the wire 6 on the supporting block 20 inside the wiring groove 9, pressing the pressing rod 14 to drive the lower pressing block 22 to move downward, and at the same time, the wire 6 on the supporting block 20 will be squeezed, thereby clamping the wire 6, and then driving the moving component and one end of the wire 6 to move in the wiring groove 9 toward the controller 3. After moving a certain distance, the pressing rod 14 can be released, and finally one end of the wire 6 is electrically connected to the controller 3. The wiring groove 9 and the protective frame 4 can protect the wire 6 to prevent the wire 6 from being exposed on the training platform 1 and causing damage.

[0022] like Figure 8 and Fig. 9As shown, the moving component includes a slider 16 slidably arranged inside the wiring groove 9, a supporting block 20 for placing the wire 6 is arranged on the top of the slider 16, support rods 21 are arranged at the four corners of the top of the slider 16, a support block 8 is arranged on the top of the support rod 21, a pressing rod 14 is movably arranged inside the support block 8, an extrusion block for extruding the wire 6 is arranged at the bottom of the pressing rod 14, a reset spring 23 is sleeved on the outside of the pressing rod 14, one end of the reset spring 23 is connected to the bottom of the support block 8, and the other end of the reset spring 23 is connected to the top of the lower pressing block 22, and a limit groove for the limit block 25 to move is opened on the lower surface of the support block 8.

[0023] Through the cooperation between the pressing block 22 and the supporting block 20, the wire 6 can be effectively squeezed, so that the wire 6 is firmly clamped, and the wire 6 is conveniently driven to move.

[0024] like Figure 8 and Fig. 9 As shown, connecting blocks 24 are rotatably provided on both sides of the top of the lower pressing block 22, and moving blocks 15 are rotatably provided on the other ends of the two connecting blocks 24. An inclined groove 18 is provided inside the moving block 15, and a positioning rod 19 is slidably provided inside the inclined groove 18. Limiting rods 13 are provided on both sides of the top of the positioning rod 19, and one end of the limiting rod 13 extends to the outside of the supporting block 8.

[0025] By moving the pressing block 22 downward, the two connecting blocks 24 will be driven to approach at the same time, and the positioning rod 19 inside the connecting block 24 will move upward under the guidance of the inclined groove 18, thereby breaking away from the contact with the positioning hole on the surface of the training platform 1, making it convenient to drive the moving component and the wire 6 to move.

[0026] like Fig. 9 As shown, a limit block 25 is disposed on the top of each of the two moving blocks 15 .

[0027] By using the limiting block 25 to slide in the limiting groove, the moving block 15 can be effectively prevented from accidentally falling during the moving process.

[0028] like Figure 1 and Figure 8 As shown, a positioning hole matched with the positioning rod 19 is provided on the upper surface of the training platform 1 , and a moving groove for the pressing rod 14 to move is provided inside the protective frame 4 .

[0029] By inserting the positioning rod 19 into the positioning hole on the surface of the training platform 1 , it is possible to effectively prevent the moving assembly from shaking randomly on the surface of the training platform 1 when not in operation.

[0030] like Figure 1 As shown, a guide roller 5 for guiding a wire 6 is rotatably provided on one side outer wall of the training platform 1 .

[0031] By providing the guide roller 5, it is possible to effectively prevent the wire 6 from having unnecessary friction with the corner of the training table 1 during movement. This can not only further reduce the wear of the wire 6, but also extend the service life of the wire 6, ensuring its performance and reliability during the training process. This not only improves the efficiency of the training equipment, but also ensures the safety and smoothness of the training process.

[0032] like Figure 7 and Fig.10 As shown, a rotating rod 11 is rotatably provided at the bottom of the training platform 1, a worm 27 is provided at one end of the rotating rod 11, a spiral groove 12 is provided on the outside of the rotating rod 11, an L-shaped push rod 17 is provided at the bottom of the slider 16, which is in contact with the spiral groove 12 and pushes the rotating rod 11 to rotate, and a movable groove for the L-shaped push rod 17 to move is provided inside the wiring groove 9.

[0033] By driving the L-shaped push rod 17 to move and cooperating with the precise operation of the spiral groove 12 outside the rotating rod 11, the rotating rod 11 is effectively driven to perform precise rotation.

[0034] like Fig.10 As shown, the pay-off assembly includes a first gear 29 and a second gear 31 rotatably disposed inside the mounting frame 7, the first gear 29 and the second gear 31 are meshingly connected, a first squeezing roller 28 is disposed on the top of the first gear 29, and a second squeezing roller 30 is disposed on the top of the second gear 31.

[0035] The conductor 6 can be moved by the mutual squeezing of the first squeezing roller 28 and the second squeezing roller 30 , and the conductor 6 can be released and reeled in conveniently by the same-direction rotation and the opposite-direction rotation of the first squeezing roller 28 and the second squeezing roller 30 .

[0036] like Figure 6 As shown, a worm wheel 26 meshingly connected with a worm 27 is disposed on the top of the second squeezing roller 30 .

[0037] The worm 27 outside the rotating rod 11 rotates, which further drives the worm wheel 26 meshing with the worm 27 to rotate. At the same time, the second squeezing roller 30 at the bottom of the worm wheel 26 rotates, which also drives the wire release assembly to work.

[0038] like Figure 1 As shown, the cylinder training assembly includes a cylinder 2 movably arranged on the top of a training platform 1 , an air connection end of the cylinder 2 is connected to an air pipe 10 , and the other end of the air pipe 10 is connected to a controller 3 .

[0039] The cylinder training kit is used to facilitate trainees to build and debug the pneumatic system on the training table 1. Through practical operations, students can deepen their understanding of pneumatic technology and cultivate their practical skills.

[0040] Working principle: when it is necessary to connect the wire 6 to the cylinder training assembly, first pass one end of the wire 6 between the first squeezing roller 28 and the second squeezing roller 30, and then place the wire 6 on the supporting block 20 inside the wiring groove 9. At this time, press the pressing rod 14 to drive the lower pressing block 22 to move downward, and at the same time, squeeze the wire 6 on the supporting block 20, so as to clamp the wire 6. While the lower pressing block 22 moves downward, it also drives the two connecting blocks 24 to approach at the same time, and the positioning rod 19 inside the connecting block 24 will move upward under the guidance of the inclined groove 18, thereby breaking away from the contact with the positioning hole on the surface of the training platform 1. At this time, the moving assembly and one end of the wire 6 can be driven to move in the wiring groove 9 toward the direction of the controller 3. After moving a certain distance, the pressing rod 14 can be released, and the lower pressing block 22 at the bottom of the pressing rod 14 will move upward under the action of the reset spring 23, and at the same time, the two connecting blocks 24 will also move away from each other, so that the positioning rod 19 inside the connecting block 24 will move downward under the guidance of the inclined groove 18. The moving assembly 10 can be moved so that the positioning rod 19 is inserted into the positioning hole on the surface of the training platform 1 to prevent the moving assembly from shaking at will. Finally, one end of the wire 6 can be electrically connected to the controller 3. The wire 6 can be protected by the wiring groove 9 and the protective frame 4 to prevent the wire 6 from being exposed on the training platform 1 and causing damage. When the moving assembly moves, it will also drive the L-shaped push rod 17 to move, and cooperate with the spiral groove 12 on the outside of the rotating rod 11 to drive the rotating rod 11 to rotate. At the same time, the worm 27 on the outside of the rotating rod 11 will also rotate, further driving the worm wheel 26 meshing with the worm 27 to rotate, and at the same time, the second squeezing roller 30 and the second gear 31 at the bottom of the worm wheel 26 will also rotate. When the second gear 31 rotates, it will also drive the first gear 29 and the first squeezing roller 28 to rotate. Under the mutual squeezing of the first squeezing roller 28 and the second squeezing roller 30, the wire 6 can be driven to move. The first squeezing roller 28 and the second squeezing roller 30 rotate in the same direction and the opposite direction, so as to facilitate the release and reeling of the wire 6.

[0041] The above embodiments only express a cylinder motion control training platform or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of protection of the present invention.
