Description

An electro-hydraulic servo integrated machine Technical Field

[0001] This utility model relates to the field of servo integrated machine technology, specifically an electro-hydraulic servo integrated machine. Background Technology

[0002] An electro-hydraulic servo integrated machine is an advanced device that integrates components such as a high-power servo motor, servo driver, and hydraulic pump.

[0003] The working principle of the electro-hydraulic servo integrated machine mainly relies on the control computer. The actual position of the load is fed back to the servo amplifier via a displacement sensor, forming a closed-loop control system. The control computer calculates the current control signal based on the target position given by the system, converts it to a digital signal (D / A) converter, and then transmits it to the servo amplifier. The output current of the servo amplifier drives the valve core of the electro-hydraulic servo valve to move, which is powered by a hydraulic source to drive the hydraulic cylinder to achieve the loading function. By continuously comparing the error between the given command signal and the feedback signal, and after appropriate PID control calculations, a displacement closed-loop control system is formed, ensuring that the actual output of the system matches the expected value.

[0004] However, in electro-hydraulic servo integrated machines, the hydraulic pump and oil tank need to be connected via a delivery hose, and this hose needs to be replaced after a certain period of use. Traditional connection methods mostly involve flanges and bolts, making pipe replacement cumbersome and time-consuming. Therefore, those skilled in the art have provided an electro-hydraulic servo integrated machine to solve the problems mentioned in the background section. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an electro-hydraulic servo integrated machine to solve the problems that in the electro-hydraulic servo integrated machine, the hydraulic pump and the oil tank need to be connected through a delivery hose, and the delivery hose needs to be replaced after a certain period of use. In addition, the traditional connection methods are mostly flange and bolt connections, which are cumbersome and time-consuming when replacing the pipeline.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an electro-hydraulic servo integrated machine, comprising an integrated servo motor, an oil tank, and a hydraulic pump. The oil tank is disposed on one side of the integrated servo motor, and the integrated servo motor is driven and connected to the hydraulic pump. A first connecting pipe is installed between the hydraulic pump and the top of the oil tank. An extension pipe is installed at the upper end of the first connecting pipe, and a tapered end is installed at the upper end of the extension pipe. A tapered ring is fitted on the extension pipe. A second connecting pipe is connected to the first connecting pipe, and an annular protrusion is installed on the second connecting pipe. The annular protrusion has a second movable groove and a first movable groove opened from the inside to the outside. A limit rod is inserted into the first movable groove, and a limit ring is installed on the limit rod. A spring is connected to one side of the limit ring. A slanted locking block is inserted into the second movable groove.

[0009] Preferably, the limiting rod is fixedly connected to the inclined plate block.

[0010] Preferably, the outer wall of the limiting ring contacts the inner wall of the first movable groove, the spring is sleeved with the limiting rod, one end of the spring is fixedly connected to the limiting ring, and the other end of the spring is in abutting contact with the inner wall of the first movable groove on the side away from the second movable groove.

[0011] Preferably, the inclined plate contactes the bottom side wall of the conical end. When connecting the second connecting pipe to the first connecting pipe, the second connecting pipe is inserted after the conical end on the first connecting pipe is aligned with it. After being squeezed, the inclined plate rebounds through the spring and engages with the bottom plane of the cylindrical end, thereby connecting and fixing the second connecting pipe to the first connecting pipe.

[0012] Preferably, the conical ring and the extension tube are slidably sleeved. When the connection between the first connecting tube and the second connecting tube is broken, the second connecting tube continues to move deeper into the first connecting tube, so that the inclined plate block sweeps past the conical ring. Then, the second connecting tube is pulled outward. During the outward movement, the second connecting tube causes the conical ring to contact the conical end. When the conical ring and the conical end press against each other, the second connecting tube continues to move outward. At this time, since the conical ring and the conical end are closed, the inclined plate block can disengage from the conical end, thereby achieving the effect of quick assembly and disassembly.

[0013] Preferably, a connecting hose is connected between the two second connecting pipes. The integrated servo motor in the electro-hydraulic servo machine sends an electrical control signal, which is converted into a hydraulic flow or pressure signal to drive the hydraulic pump to work, thereby delivering oil through the connecting hose.

[0014] Preferably, a sealing ring is installed on the peripheral sidewall of the tapered end to improve the sealing performance after the second connecting pipe is connected to the tapered end.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an electro-hydraulic servo integrated machine, which has the following beneficial effects:

[0017] Through design, this practical internal electro-hydraulic servo integrated machine includes an oil tank, an integrated servo motor, and a hydraulic pump. First connecting pipes are installed on the oil tank and hydraulic pump. Two first connecting pipes are connected to a delivery hose via a second connecting pipe. An extension pipe is installed on the first connecting pipe, with a tapered end at one end. A tapered ring is movably fitted onto the extension pipe. A second movable groove and a first movable groove are formed within an annular protrusion on the second connecting pipe. A limit rod is inserted into the first movable groove, and a sloping locking block connected to the limit rod is provided in the second movable groove. When connecting the second connecting pipe to the first connecting pipe, insert the second connecting pipe after aligning it with the tapered end of the first connecting pipe. The tapered end is then engaged and secured by the beveled locking block. When disconnecting the first and second connecting pipes, continue to move the second connecting pipe downwards, allowing the beveled locking block to pass slightly past the tapered ring. Then, pull the second connecting pipe outwards. As the second connecting pipe moves outwards, it causes the tapered ring to contact the tapered end. At this point, because the tapered ring and the tapered end are closed, the beveled locking block is able to disengage from the tapered end, thus achieving a quick disassembly and assembly effect, facilitating the replacement of the connecting hose.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution: an electro-hydraulic servo integrated machine (see Figures 1, 2, 3, and 4). It includes an integrated servo motor 2, an oil tank 1, and a hydraulic pump 3. The oil tank 1 is located on one side of the integrated servo motor 2. The integrated servo motor 2 is connected to the hydraulic pump 3. A first connecting pipe 4 is installed between the hydraulic pump 3 and the top of the oil tank 1. An extension pipe 401 is installed at the upper end of the first connecting pipe 4. A tapered end 402 is installed at the upper end of the extension pipe 401. A tapered ring 404 is fitted on the first connecting pipe 4, and a second connecting pipe 5 is connected to the first connecting pipe 4. An annular protrusion 6 is installed on the second connecting pipe 5. The annular protrusion 6 has a second movable groove 602 and a first movable groove 601 from the inside to the outside. A limit rod 603 is inserted into the first movable groove 601. A limit ring 6031 is installed on the limit rod 603. A spring 605 is connected to one side of the limit ring 6031. A sloped block 604 is inserted into the second movable groove 602. The limit rod 603 and the sloped block 604 are fixedly connected.

[0025] Please refer to Figures 1, 2, 3, and 4. The outer wall of the limiting ring 6031 contacts the inner wall of the first movable groove 601. The spring 605 is sleeved with the limiting rod 603. One end of the spring 605 is fixedly connected to the limiting ring 6031, and the other end of the spring 605 is in contact with the inner wall of the first movable groove 601 away from the second movable groove 602. The inclined block 604 contacts the bottom side wall of the conical end 402. When connecting the second connecting pipe 5 to the first connecting pipe 4, the second connecting pipe 5 is inserted after aligning with the conical end 402 on the first connecting pipe 4. After being squeezed, the inclined block 604 rebounds through the spring 605 and engages with the bottom plane of the cylindrical end, thereby connecting and fixing the second connecting pipe 5 and the first connecting pipe 4. The conical ring 404 is slidably sleeved with the extension pipe 401. When the connection between the first connecting pipe 4 and the second connecting pipe 5 is broken, the second connecting pipe 5 continues to move towards the first... The connecting pipe 4 moves downward, causing the inclined block 604 to pass over the conical ring 404. Then, the second connecting pipe 5 is pulled outward. During the outward movement, the second connecting pipe 5 causes the conical ring 404 to contact the conical end 402. After the conical ring 404 and the conical end 402 are pressed together, the second connecting pipe 5 continues to move outward. At this time, since the conical ring 404 and the conical end 402 are closed, the inclined block 604 can disengage from the conical end 402, thereby achieving the effect of quick disassembly and assembly. A connecting hose 7 is connected between the two second connecting pipes 5. The integrated servo motor 2 in the electro-hydraulic servo machine sends an electrical control signal, which is converted into a hydraulic flow or pressure signal to drive the hydraulic pump 3 to work, thereby delivering oil through the connecting hose 7. A sealing ring 403 is installed on the peripheral wall of the conical end 402 to improve the sealing performance after the second connecting pipe 5 is connected to the conical end 402.

[0026] This practical internal electro-hydraulic servo integrated machine includes an oil tank 1, an integrated drive servo motor 2, and a hydraulic pump 3. The integrated drive servo motor 2 consists of a servo driver and a servo drive motor. A first connecting pipe 4 is installed on the oil tank 1 and the hydraulic pump 3, and a delivery hose is connected to the two first connecting pipes 4 through a second connecting pipe 5. The integrated drive servo motor 2 in the electro-hydraulic servo integrated machine sends an electrical control signal, which is converted into a hydraulic flow or pressure signal to drive the hydraulic pump 3 to work.

[0027] An extension tube 401 is installed on the first connecting tube 4. A tapered end 402 is installed at the end of the extension tube 401. A tapered ring 404 is movably sleeved on the extension tube 401. An annular protrusion 6 is installed on the second connecting tube 5. A second movable groove 602 and a first movable groove 601 are sequentially opened from the inside to the outside of the annular protrusion 6. A limiting rod 603 is inserted into the first movable groove 601. A limiting ring 6031 is installed on the limiting rod 603. The limiting ring 6031 is also located in the first movable groove 601. A sloping block 604 is installed at one end of the limiting rod 603 facing the second movable groove 602. The sloping block 604 is located in the second movable groove 602. A spring 605 is sleeved on the part of the limiting rod 603 located in the first movable groove 601. One end of the spring 605 is connected to the limiting ring 6031, and the other end is pressed against the inner wall of the end away from the second movable groove 602.

[0028] When connecting the second connecting pipe 5 to the first connecting pipe 4, the tapered end 402 on the second connecting pipe 5 is aligned with the tapered end 402 on the first connecting pipe 4 and then inserted. After being squeezed, the inclined block 604 rebounds through the spring 605 and engages with the bottom plane of the cylindrical end, thereby connecting and fixing the second connecting pipe 5 and the first connecting pipe 4. A sealing ring 403 is installed on the outer wall of the tapered end 402 to improve the sealing performance after the second connecting pipe 5 and the tapered end 402 are connected, forming an effective delivery pipeline with the connecting hose 7.

[0029] A tapered ring 404, with its slope opposite to that of the tapered end 402, is fitted onto the extension tube 401. When it is necessary to disconnect the first connecting tube 4 from the second connecting tube 5, the second connecting tube 5 is moved further down into the first connecting tube 4, causing the inclined block 604 to pass over the tapered ring 404. Then, the second connecting tube 5 is pulled outward. During the outward movement, the tapered ring 404 comes into contact with the tapered end 402. After the tapered ring 404 and the tapered end 402 come into contact, the second connecting tube 5 continues to move outward. At this time, because the tapered ring 404 and the tapered end 402 are closed, the inclined block 604 is able to disengage from the tapered end 402, thereby achieving the effect of quick disassembly and assembly, and facilitating the replacement of the connecting hose 7.
