[0049] In the description of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise clearly defined. In addition, unless otherwise clearly defined and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0051] The present invention provides a hydraulic and pneumatic comprehensive training device, which includes a first test bench 1 and a second test bench 2. The first test bench 1 is provided with a training component, and the training component is used for loading, positioning, clamping and pressing of workpieces. The second test bench 2 is provided with a control component, and the control component is used to control the operation of the training component and to perform principle tests of hydraulic and pneumatic circuits.

[0052] Specifically, see Figure 1 The training device includes two test benches. The first test bench 1 is equipped with hydraulic and pneumatic operable mechanisms, which allows students to control the corresponding mechanisms on the second test bench 2 for practical operation, which is conducive to the development of teaching. At the same time, the second test bench 2 is another independent area, which can also carry out principle tests of various hydraulic and pneumatic circuits.

[0053] As an optional implementation, in some embodiments, the training component includes a displacement mechanism, which includes a driving member 3, a guide rail 4, and a slide 5 slidably arranged on the guide rail 4, the guide rail 4 is arranged on the first test bench 1 through a guide rail pad 6, the output end of the driving member 3 is connected to the slide 5, the slide 5 has a housing mounting position 7, the housing mounting position 7 is provided with a positioning hole 8, and a limit block 9 and a first oil cylinder 10 are arranged on the slide 5. Among them, the housing on the housing mounting position 7 is successively limited by the limit block 9 to move close to the housing to achieve preliminary positioning, and the expansion pin is matched with the positioning hole 8 to achieve secondary positioning, and the first oil cylinder 10 rotates toward the housing to press the housing.

[0054] Specifically, see Figure 2 , this displacement mechanism is in the middle of the first test bench 1, and the slide 5 can slide to the two ends of the guide rail 4, so that after the installation of the casing is completed, it can slide to the corresponding mechanism for pole piece loading and bearing and pin pressing. The installation of the casing is specifically as follows: first manually place the casing on the casing installation position 7, and preliminarily position the casing through the limit block 9 near the casing installation position 7 to prevent it from moving, and then align the positioning hole of the casing with the positioning hole 8 on the slide 5, and insert the expansion pin into the two positioning holes. After the expansion pin is ventilated and expanded, the precise positioning of the casing can be achieved, and finally the casing is pressed by the rotation of the first oil cylinder 9 to ensure that the casing can be firmly on the slide 5, and the positioning process of the casing is completed. In addition, the driving part 3 preferably adopts a servo motor, and the first oil cylinder 9 preferably adopts an angle oil cylinder. Before the unloading process, the expansion pin and the angle oil cylinder need to always maintain a pressure state to prepare for subsequent processes.

[0055] In the above embodiment, further, the training component includes a feeding mechanism, which is arranged near the first end of the guide rail 4, and includes a pole piece bin 11, a first cylinder 12, a second cylinder 13 and a third cylinder 14. The pole piece bin 11 is connected to a first feeding position, the output end of the first cylinder 12 is connected to a first push plate 15, the first push plate 15 is between the pole piece bin 11 and the first feeding position, the output end of the second cylinder 13 is connected to a sucker 16, and the output end of the third cylinder 14 is connected to the second cylinder 13 through a connecting member. When the slide 5 slides to the first end of the guide rail 4, the first cylinder 12 drives the first push plate 15 to move so that the pole piece in the pole piece bin 11 is pushed into the first feeding position, the second cylinder 13 drives the sucker 16 to approach the first feeding position so that the sucker 16 sucks the pole piece, and the third cylinder 14 drives the sucker 16 to move toward the casing so that the sucker 16 releases the pole piece.

[0056] Specifically, see again Figure 2 Taking this view as an example, the first end of the guide rail 4 is an end that is tilted upward, and the slide 5 slides to the end of the first end of the guide rail 4. Figure 3 , the first cylinder 12 pushes the electrode into the first loading position through the first push plate 15, the second cylinder 13 drives the sucker 16 to move downward so that the sucker 16 sucks the electrode, and after the sucker 16 sucks the electrode, the second cylinder 13 drives the sucker 16 to move upward. At this time, the third cylinder 14 is started to move the second cylinder 13 and the sucker 16 together to the top of the housing, and the second cylinder 13 drives the sucker 16 to move downward again, aligning the electrode hole with the connecting pin of the housing and releasing the electrode at the same time to install the electrode. In addition, the sucker 16 is preferably a vacuum sucker.

[0057] In the above embodiment, further, the training component also includes a clamping mechanism, which includes a locking bin 17, a fourth cylinder 18, a fifth cylinder 19 and a sixth cylinder 20. The locking bin 17 is connected to a second loading position, the output end of the fourth cylinder 18 is connected to a second push plate 21, the second push plate 21 is between the locking bin 17 and the second loading position, the output end of the fifth cylinder 19 is connected to a first clamping member 22, and the output end of the sixth cylinder 20 is connected to the fifth cylinder 19 through a connecting member. Among them, the fourth cylinder 18 drives the second push plate 21 to move so that the locking pad in the locking bin 17 is pushed into the second loading position, the fifth cylinder 19 drives the first clamping member 22 to approach the second loading position so that the first clamping member 22 clamps the locking pad, and the sixth cylinder 20 drives the first clamping member 22 to move toward the housing so that the first clamping member 22 releases the locking pad.

[0058] Specifically, see Figure 4After the pole piece is in place, when the third cylinder 14 returns to the initial position, the fourth cylinder 18 pushes the lock pad into the second loading position through the second push plate 21, and the fifth cylinder 19 drives the first clamp 22 to move downward so that the first clamp 22 clamps the lock pad. After the first clamp 22 clamps the lock pad, the fifth cylinder 19 drives the first clamp 22 to move upward. At this time, the sixth cylinder 20 is started, and the fifth cylinder 19 and the first clamp 22 are moved to the top of the housing together, and the lock hole of the lock pad is aligned with the connecting pin of the housing. The fifth cylinder 19 drives the first clamp 22 to move downward again. After it is in place, the first clamp 22 drives the lock to rotate 90°, so that the flange inside the lock cooperates with the groove of the connecting pin, thereby clamping the pole piece, and thus completing the installation of the pole piece. In addition, the first clamp 22 preferably adopts MRHQ swing claw.

[0059] In the above embodiment, further, a buffer 23 is provided at the output end of the sixth cylinder 20, and the buffer 23 is used to adjust the movement speed of the output end of the sixth cylinder 20. Figure 3 After the buffer 23 is installed, the movement speed of the output end of the sixth cylinder 20 can be appropriately slowed down so as to achieve accurate positioning of the first clamping member 22.

[0060] As an optional embodiment, in some embodiments, the training component further includes a press-fitting mechanism, which is arranged near the second end of the guide rail 4, and includes a bearing bin 24, a pin guide bin 26, a seventh cylinder 27, an eighth cylinder 28, and a second oil cylinder 29. A third loading position is arranged at the discharge port of the bearing bin 24, and a third push plate 30 is connected to the output end of the seventh cylinder 27. The third push plate 30 is located below the discharge port of the bearing bin 24, and a second clamp 31 is connected to the output end of the eighth cylinder 28. When the slide 5 slides to the second end of the guide rail 4, the seventh cylinder 27 drives the third push plate 30 to move so that the bearing is pushed into the third loading position, and the eighth cylinder 28 drives the second clamp 31 to clamp the bearing and move the bearing to the bearing mounting hole of the housing. The pin in the pin guide bin 26 is transported to the second oil cylinder 29 through the vibration plate 32 and the straight vibrator 33, and the second oil cylinder 29 is used to press the pin into the pin hole of the housing.

[0061] Specifically, see again Figure 2 Taking this view as an example, the second end of the guide rail 4 is an end that is tilted downward, and the slide 5 slides to the end of the second end of the guide rail 4. Figure 6 and Figure 7, the seventh cylinder 27 drives the third push plate 30 to push the bearing into the third loading position, the eighth cylinder 28 drives the second clamping member 31 to approach the third loading position to clamp the bearing, and then rotates 90° so that the bearing clamped by the second clamping member 31 is above the bearing mounting hole of the housing, and then the inner ring hole of the bearing is guided by the bearing pressing head (with a tapered guide) of the electric cylinder 25, and finally the second clamping member 31 releases the bearing, and the bearing pressing head of the electric cylinder 25 continues to move downward until the outer ring of the bearing is pressed into place. In addition, the second clamping member 31 is preferably a pneumatic finger.

[0062] It should be noted here that, since two bearings need to be installed in the same hole, the pressing depth of each bearing is not consistent, and each bearing needs to be positioned and corrected by a guide head before being pressed in. This cannot be achieved by using an oil cylinder for downward pressing, so an electric cylinder 23 is used instead.

[0063] After the two bearings are press-fitted, the pin is automatically fed from the pin guide bin 26 to the second oil cylinder 29 through the vibration plate 32 and the straight vibrator 33, and finally the second oil cylinder 29 presses the pin into the pin hole of the casing until the press-fitting process of the pin is completed. In addition, the vibration plate 32 is preferably a circular vibration plate, and the second oil cylinder 29 is preferably a press-fitting oil cylinder.

[0064] In summary of the above embodiments, the operable mechanisms added to the training device can realize practical application operations such as workpiece loading, positioning, clamping, workpiece conveying, material loading, suction, transfer, and pressing, and can be used for training on system installation and debugging in hydraulic and pneumatic course teaching, which is conducive to the development of teaching.

[0065] As an optional implementation, in some embodiments, the control component includes a PLC module 34, a power module 35, a relay module 36 and a control button module 37. The PLC module 34 is used to receive and process input signals and output corresponding control signals to the training component, the power module 35 is used to provide power for the operation of the training component, the relay module 36 is used to provide protection for the circuit of the training component, and the control button module 37 is used to control the start and stop of the training component. Fig. 9 or Fig.10 The power module 35 also includes a 220V AC power module and a 24V DC power module, and the relay module 36 also includes a time relay module and an intermediate relay module. Through the above modules, electrical control and PLC program control of hydraulic and pneumatic circuits with different control requirements can be achieved.

[0066] As an optional implementation, in some embodiments, the second test bench is provided with an operating table 38, an embedded integrated machine 39 is provided on the operating table 38, and two opposite sides of the operating table 38 are provided with inwardly recessed component installation areas 40, the two component installation areas 40 are respectively installed with pneumatic components and hydraulic components, and the two component installation areas 40 are both provided with wiring grooves 41. Figures 8 to 10 The operation table 38 is equipped with an embedded all-in-one machine 39 (computer), which can solve the problem of placing an additional computer or a self-provided computer. At the same time, it effectively saves equipment space and improves site efficiency and comfort during operation. In addition, the component installation area 40 of the operation table 38 adopts a sunken design, which effectively reduces the protruding height of the device and improves the aesthetics; at the same time, a wiring groove is added to reduce the mess of wiring.

[0067] In some implementations, further, the pneumatic component installation area uses a mounting plate with threaded holes with standard pitch, and the actuators, travel valves, and travel switches are fixed in position. Since the use of quick clips and T-slots to fix the components is prone to damage the clips, the installation of other components is changed to fixing with screws and mounting plates to improve the durability of the equipment. At the same time, valve components are assembled using manifolds as much as possible to facilitate the organization and classification of components and reduce the number of air pipe connections during component installation. The hydraulic component installation area is also sunken, and also uses a mounting plate with threaded holes with standard pitch, and the actuators, travel valves, and travel switches are fixed in position; embedded pressure gauges and relief valves are fixed in position, and other components are connected to the mounting plate with screws, and the same components are installed on the same oil-made base plate as much as possible.

[0068] As an optional implementation, in some embodiments, the first test bench 1 has two placement spaces, one of which is enclosed by a baffle 42 and the other is open. The second test bench 2 is provided with a storage cabinet 43 and a drawer 44, and storage shelves (not shown) are installed in the storage cabinet 43 at intervals. One side of the second test bench 2 has a recessed space 45, and the recessed space 45 is provided with a hanger 46 for hanging a hydraulic oil pipe.

[0069] Specifically, the hollow part of the first test bench 1 is separated by a baffle 42, and the space behind the baffle 42 is used to install the oil and air pipe joints and air control valves, and the pipe and line insertion holes are opened to facilitate the pipe and line routing; the front of the baffle 42 is printed with the unit LOGO and other pattern information, and two five-hole sockets are installed on the right side to provide 220V AC power to the hydraulic pump station and the air pump, and the pipe and line insertion holes are opened. The left sealing plate is used to install the pneumatic triple. The right side space of the first test bench 1 is used to place the hydraulic pump station and the air compressor respectively. Various installation holes are opened on the first test bench 1 for connection. The control box also includes a touch screen, which cooperates with the PLC on the second test bench 2 to control the operation of the hydraulic\pneumatic driven mechanical device. The first test bench 1 is also provided with an industrial three-color warning light 48 for displaying the operating status of the equipment. The right side of the second test bench 2 adds a concave hydraulic oil pipe storage and placement rack 46 to solve the problem that the external hydraulic oil pipe affects the overall aesthetics and dustproof of the machine, and improves the service life of hydraulic components. The second test bench 2 is provided with a storage cabinet 43 and a push-pull drawer 44, which can better place the hydraulic components for practical training.

[0070] As an optional implementation, in some embodiments, the bottom of the first test bench 1 and the bottom of the second test bench 2 are both provided with a Forma wheel 47. In this way, the movement and transportation of the equipment is facilitated, and at the same time, the Forma wheel 47 has excellent shock absorption ability, which can effectively reduce the vibration between the equipment and the ground, thereby protecting the equipment and extending its service life.
