[0022] like Figure 1-4As shown, an embodiment of the present invention provides an automated oil filling device for a hydraulic device, wherein the device includes a vacuum tank 1, a vacuum pump 2, a circulating pump 3, a hydraulic oil valve seat assembly 4, an electric control cabinet 5, a fixed tool 7 and a rotating mechanism 8, wherein the vacuum tank 1 is an oil storage tank, the vacuum pump 2 is connected to the vacuum tank 1 and the hydraulic device 75, and is used to evacuate the oil storage unit of the vacuum tank 1 and the hydraulic device 75 before oil filling, the hydraulic oil valve seat assembly 4 is connected to the vacuum tank 1, and is used to control the opening and closing of the oil circuit, the circulating pump 3 is connected to the hydraulic oil valve seat assembly 4 and the hydraulic device, and is used to realize the oil filling cycle of the vacuum tank 1 and the hydraulic device 75 when the oil circuit is opened, the fixed tool 7 is used to fix the hydraulic device 75, the rotating mechanism 8 is connected to the hydraulic device 75, and is used to drive the hydraulic device 75 to rotate, and the electric control cabinet 5 is used to control the opening and closing of the hydraulic oil valve seat assembly 4, control the start and stop of the vacuum pump 2 and the circulating pump 3, and control the rotating mechanism 8 to perform a rotation operation.

[0023] The rotating mechanism 8 can be connected to the hydraulic device 75 via a fixing device 7 .

[0024] Through the above technical solution, the vacuum pump can be controlled by the electric control cabinet to reduce the bubbles of the hydraulic oil entering the container, the circulation pump can be controlled by the electric control cabinet to realize the oil filling circulation, and the rotating mechanism can be controlled by the electric control cabinet to drive the hydraulic device to rotate to realize the exhaust of the oil filling process. In this way, the hydraulic device can be automatically and reliably filled with oil.

[0025] Specifically, by evacuating the vacuum tank 1 and the oil storage unit of the hydraulic device 75, the oil storage environment can have a lower vacuum degree. The lower the vacuum degree, the fewer bubbles in the hydraulic oil, and the more stable the hydraulic device operation output process. In addition, under normal circumstances, the hydraulic oil maintains a high pressure. By maintaining a certain vacuum degree to perform the oil filling operation, it is conducive to the smooth and reliable oil filling operation. By rotating the hydraulic device at different angles, the gap inside the hydraulic device is filled with oil, thereby completely eliminating the bubbles inside the hydraulic device.

[0026] In addition, through the oil filling cycle between the vacuum tank and the hydraulic device, the hydraulic device is continuously filled with oil, and the hydraulic device enables output during the process, so that the bubbles in the action actuator of the hydraulic device are discharged from the hydraulic device. This can further ensure the output stability of the hydraulic device and make the gas inside the hydraulic device clean.

[0027] According to an embodiment of the present invention, the device further comprises a rotatable operating display screen 6 .

[0028] Among them, the rotatable operation display screen can be used for human-computer interaction, for example, the staff inputs relevant control parameters through the display screen.

[0029] For example, the rotatable operating display screen can be an embedded rotating operating screen. When operation is needed, the operating screen can be rotated to unfold for operation, and when not needed, it can be hidden for a more aesthetically pleasing design.

[0030] In this way, the rotation process of the hydraulic device can be made more intuitive and controllable.

[0031] According to one embodiment of the present invention, the vacuum tank 1 includes an oil outlet 10, an oil return port 11 and a vacuum port 12, and the oil outlet 10, the oil return port 11 and the vacuum port 12 extend to the rotating mechanism 8 through pipelines to be connected to the corresponding interfaces of the hydraulic device 75.

[0032] The hydraulic oil stored in the vacuum tank is supplied to the hydraulic device through the oil outlet, and the hydraulic oil in the hydraulic device can be circulated back to the vacuum tank through the oil return port. By providing the vacuum port, the hydraulic device can be evacuated while the vacuum tank is evacuated.

[0033] According to one embodiment of the present invention, the fixing tool 7 includes a fixing cylinder 71, a support member 72, a plunger top block 73 and a supporting tool block 74. The fixing cylinder 71 passes through the upper part of the support member 72 and is connected to the plunger top block 73. The supporting tool block 74 is arranged at the bottom of the support member 72. The hydraulic device 75 is arranged on the supporting tool block 74. The fixing cylinder 71 drives the plunger top block 73 to move downward to support the plunger of the hydraulic device 75, thereby realizing the fixation of the hydraulic device 75.

[0034] The hydraulic device can be quickly changed by replacing the plunger top block and the support fixture block. The support fixture block can make the hydraulic device and the support member match with each other.

[0035] According to an embodiment of the present invention, the support member 72 is a C-shaped support member.

[0036] For example, the cylinder rod of the fixed cylinder passes through the upper part of the C-shaped support and is connected to the upper part of the plunger top block. The lower part of the plunger top block has a protrusion. When the fixed cylinder drives the plunger top block to move downward, the protrusion contacts and supports the plunger of the hydraulic device, thereby fixing the hydraulic device.

[0037] According to one embodiment of the present invention, the device further comprises a prompting unit 6 for issuing a prompt when the oil filling of the hydraulic device 75 is completed.

[0038] That is, when the oil filling is completed, the electric control cabinet can send a prompt instruction to the prompt unit so that the prompt unit can issue a corresponding prompt in time, so that the staff can know the completion status of the oil filling in time.

[0039] According to an embodiment of the present invention, the prompt unit 6 is a three-color buzzing indicator light.

[0040] That is, sound and light prompts can be issued through the three-color buzzer indicator light.

[0041] According to an embodiment of the present invention, the rotation angle range of the hydraulic device 75 is -90° to 90°.

[0042] For example, with the horizontal line as a reference, the hydraulic device can rotate upward by 90° and downward by -90°.

[0043] The operation process of the automatic oil filling equipment of the present invention is described below with reference to examples.

[0044] 1. Before performing the oil supply operation, make sure that the equipment is connected to the hydraulic device;

[0045] 2. Input the model of the hydraulic device through the display screen to automatically match the oil filling parameters, such as: oil filling cycle pressure, equipment vacuum, oil filling time, etc.;

[0046] 3. The equipment automatically starts vacuuming and self-circulation, so that the equipment body reaches a certain vacuum degree and ensures the low vacuum degree of the hydraulic oil;

[0047] 4. Execute the oil filling and oil filling cycle, and the automated oil filling equipment automatically rotates at different angles (plus or minus 90°) to realize the oil filling and bubble removal process;

[0048] 5. After the oil filling cycle is completed, the equipment buzzer prompts the operator to remove the hydraulic device, and the whole process is completed.

[0049] Through experiments and verification, the overall oil filling time of the automatic oil filling equipment described in the present invention is currently about 4 hours, and no human participation is required in the entire process, which greatly improves personnel efficiency, saves personnel costs, and improves personnel health.

[0050] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0051] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0052] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
