[0017] like Figure 1-6As shown, the industrial bus digital hydraulic integrated training platform of this utility model includes a training platform 1, a single-rod digital hydraulic cylinder module 2 and a double-rod digital hydraulic cylinder module 3 mounted on the training platform 1. The single-rod digital hydraulic cylinder module 2 includes a single-rod hydraulic cylinder 4 and a first digital proportional directional valve 5 mounted on the single-rod hydraulic cylinder 4 to control its extension and retraction speed. The double-rod digital hydraulic cylinder module 3 includes a double-rod digital hydraulic cylinder 6 and a second digital proportional directional valve 7 mounted on the double-rod digital hydraulic cylinder 6 to control its extension and retraction speed. The first digital proportional directional valve 5 and the second digital proportional directional valve 7 are composite components combining digital control and hydraulic regulation functions, mainly used for precise control of the flow rate, pressure, and direction of fluids (such as hydraulic oil). Their application in digital hydraulic cylinders is conventional technology and will not be elaborated here. An analog displacement sensor 8 is mounted on the side of the single-rod hydraulic cylinder 4, and a first scale 9 is mounted on the front end of the single-rod hydraulic cylinder 4. The first piston rod 10 of the single-rod hydraulic cylinder 4 is connected to the first pull rod 801 of the analog displacement sensor 8 via a first connecting piece 11. The first scale 9 has a first guide groove 12, and first graduations 13 are provided on both sides of the first guide groove 12. The first piston rod 10 of the single-rod hydraulic cylinder 4 has a first guide shaft 14 that extends into the first guide groove 12, and the first guide shaft 14 has a first scale pointer 15 that cooperates with the first graduations 13. The analog displacement sensor 8 converts the displacement into a continuously changing voltage / current signal, providing real-time feedback on changes in the object's position. The first graduations 13 and the first scale pointer 15 cooperate to mechanically display position changes. Simultaneously, the cooperation between the first guide groove 12 on the first scale 9 and the first guide shaft 14 prevents the first piston rod 10 from twisting during extension.

[0018] Preferably, the dual-rod digital hydraulic cylinder 6 has a bus displacement sensor 16 mounted on its side and a second scale 17 mounted on its front end. The second piston rod 18 of the dual-rod digital hydraulic cylinder 6 is connected to the second pull rod 20 of the bus displacement sensor 16 via a second connecting piece 19. The second scale 17 has a second guide groove 21 and second graduations 22 on both sides of the second guide groove 21. The second piston rod 18 of the dual-rod digital hydraulic cylinder 6 has a second guide shaft 23 that extends into the second guide groove 21, and the second guide shaft 23 has a second graduation pointer 24 that cooperates with the second graduations 22.

[0019] Preferably, the first piston rod 10 has a first limiting block 25 at its front end, through which the first guide shaft 14 and the first connecting piece 11 are mounted. The second piston rod 18 has a second limiting block 26 at its front end, through which the second guide shaft 23 and the second connecting piece 19 are mounted. The limiting blocks facilitate the assembly of the connecting piece and the guide shaft.

[0020] Preferably, the single-rod hydraulic cylinder 4 has a first pressure measuring port 27 and a second pressure measuring port 28 at both ends, and the training platform 1 has a first pressure gauge 29 and a second pressure gauge 30 connected to the first pressure measuring port 27 and the second pressure measuring port 28, respectively. Specifically, the wiring points inside the first pressure measuring port 27 and the second pressure measuring port 28 are connected to the wiring points on the first pressure gauge 29 and the second pressure gauge 30, respectively, through wires, to achieve pressure detection of the single-rod hydraulic cylinder 4.

[0021] Preferably, the dual-rod digital hydraulic cylinder module 3 has a force transmitter 31 at its rear end and a contact head 32 at its front end. The training platform 1 has a collision base 33 on its surface, and a collision limiting block 34 that engages with the contact head 32 is mounted on the collision base 33. When the piston rod of the dual-rod digital hydraulic cylinder module 3 extends, the contact head 32 collides with the collision limiting block 34, thereby enabling pressure detection via the force transmitter 31.

[0022] The above description is only a preferred embodiment of the present utility model and is 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 are included within the protection scope of the present utility model.
