Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinder testing devices, and in particular to a high-efficiency hydraulic cylinder pressure testing device. Background Technology

[0002] Hydraulics is a transmission method that uses liquid as the working medium and utilizes the pressure energy of the liquid to transmit power. A hydraulic cylinder is a component that performs hydraulic energy conversion, which can convert hydraulic energy into mechanical energy of linear motion. According to the structural form of hydraulic cylinders, they can be divided into three types: piston type, plunger type, and telescopic type. Pressure testing is required during the production or testing of hydraulic cylinders.

[0003] Existing technologies can only test the cylinder at two positions: "0 stroke" or "full stroke". Although they can also test the sealing performance, they cannot meet the requirements of dynamic simulation tests with large on-site loads. To address the above issues, application number 202420696814.2 discloses a hydraulic cylinder pressure testing device, which includes a housing, a PLC control panel, and a drive mechanism. A partition is fixedly installed inside the housing, dividing the housing into an installation cavity and an oil storage cavity. Two U-shaped frames are vertically spaced at the top of the housing. A top plate is fixedly installed on the top of the upper U-shaped frame, and the lower U-shaped frame is fixedly connected to the housing. Multiple through holes are vertically opened on the top of each of the two U-shaped frames, and the multiple through holes are evenly distributed on the three side walls of the U-shaped frames. A lifting rod that is rotatably installed in the through holes of the lower U-shaped frame and is transmitted to the drive mechanism.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: only one hydraulic cylinder can be tested during use, which reduces work efficiency. Furthermore, the process of picking up and placing the hydraulic cylinder requires manual operation by staff, which presents certain inconveniences and limitations and needs to be improved.

[0005] Therefore, we propose a high-efficiency hydraulic cylinder pressure testing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency hydraulic cylinder pressure testing device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-efficiency hydraulic cylinder pressure testing device includes a base plate, a hydraulic cylinder fixing mechanism, and a testing mechanism;

[0009] Two support plates are fixedly connected to the base plate, and two identical transmission rollers are rotatably connected between the two support plates. The same conveyor belt is connected to the two transmission rollers, and a hydraulic cylinder is provided on the conveyor belt. The two support plates are provided with a fixing mechanism for limiting the hydraulic cylinder and a testing mechanism for pressure testing. One of the two support plates is provided with a control panel, and the fixing mechanism and the testing mechanism are both connected to the control panel.

[0010] The detection mechanism includes a slide rail, a slider, a spring, and a displacement sensor. A slide rail is fixedly mounted on one of the two support plates, corresponding to the output end of the hydraulic cylinder. Through the coordinated design of the motor, the two transmission rollers, the conveyor belt, and the multiple placement seats, the hydraulic cylinder can be automatically and intermittently conveyed. Through the coordinated design of the fixing mechanism and the detection mechanism, not only can the hydraulic cylinder be automatically limited and fixed, but it can also be automatically pressure tested. In summary, this enables automated pressure testing of the hydraulic cylinder, greatly improving convenience and efficiency.

[0011] Specifically, a slider is slidably connected inside the slide rail, and a displacement sensor is fixedly installed on one side of the slider. The displacement sensor is connected to the control panel, and the displacement sensor can detect the extension distance of the output end of the hydraulic cylinder.

[0012] Specifically, a spring is fixedly installed on one side of the slider, and one end of the spring is fixedly connected to the slide rail. The elastic potential energy of the spring causes the slider to push the output end of the hydraulic cylinder to retract, and the slider to return to its original shape, and the output end of the hydraulic cylinder to retract into the placement seat.

[0013] Specifically, the fixing mechanism includes a bracket, an electric push rod, a clamping plate, and a hydraulic pump. The same bracket is fixedly connected to the two support plates. An electric push rod is fixedly installed on the bracket. The output end of the electric push rod is fixedly connected to a mounting plate. A clamping plate is fixedly installed at the bottom of the mounting plate. The clamping plate is in contact with the hydraulic cylinder. Driven by the electric push rod, the mounting plate drives the clamping plate, the hydraulic pump, and the second quick connector to move downwards synchronously. This allows the clamping plate and the support plate to cooperate in clamping and limiting the hydraulic cylinder, while simultaneously ensuring a tight connection between the first quick connector and the second quick connector.

[0014] Specifically, a hydraulic pump is fixedly installed on the top of the mounting plate. The hydraulic pump is sealed to a round pipe. One end of the round pipe passes through the mounting plate and is sealed to a quick connector. The hydraulic pump and the electric push rod are both connected to the control panel. The hydraulic pump drives the hydraulic oil in the oil tank to the hydraulic cylinder, thereby causing the output end of the hydraulic cylinder to extend and push the slider, which in turn compresses the spring and drives the displacement sensor to move synchronously.

[0015] Specifically, one of the two connection ports on the hydraulic cylinder is threaded with a quick connector, which is compatible with the second quick connector, so that the hydraulic pump can deliver hydraulic oil into the hydraulic cylinder and achieve the effect of quick assembly and disassembly.

[0016] Specifically, an oil tank is fixedly installed on the top of the mounting plate, and a delivery pipe is sealed to the oil tank. One end of the delivery pipe is sealed to the hydraulic pump for storing hydraulic oil.

[0017] Specifically, an electric motor is fixedly mounted on one of the two support plates, and the output end of the electric motor is fixedly connected to one of the two transmission rollers for driving the conveyor belt. A common support plate is fixedly connected between the two support plates, and the support plate contacts the conveyor belt to achieve a lifting effect and cooperates with the clamping plate. Multiple placement seats are fixedly mounted on the conveyor belt, and the multiple placement seats are adapted to the hydraulic cylinder to facilitate the conveyor belt to transport the hydraulic cylinder and to play a certain limiting role. The electric motor is connected to the control panel.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model discloses a high-efficiency hydraulic cylinder pressure testing device. Through the coordinated design of the motor, two transmission rollers, conveyor belt, and multiple placement seats, it can achieve the effect of automatic intermittent conveying of the hydraulic cylinder. Through the coordinated design of the fixing mechanism and the detection mechanism, it can not only achieve the effect of automatically limiting and fixing the hydraulic cylinder, but also achieve the effect of automatically testing and inspecting the hydraulic cylinder. In summary, it can realize the effect of assembly line pressure testing of the hydraulic cylinder, greatly improving convenience and efficiency. Attached Figure Description

[0027] Reference Figures 1-4 A high-efficiency hydraulic cylinder pressure testing device includes a base plate 1, a hydraulic cylinder 6 fixing mechanism, and a testing mechanism;

[0028] Two support plates 2 are fixedly connected to the base plate 1. Two identical transmission rollers 3 are rotatably connected between the two support plates 2. The same conveyor belt 4 is connected to the two transmission rollers 3. A hydraulic cylinder 6 is provided on the conveyor belt 4. A fixing mechanism for limiting the hydraulic cylinder 6 and a testing mechanism for pressure testing are provided on the two support plates 2. A control panel 21 is provided on one of the two support plates 2. The fixing mechanism and the testing mechanism are both connected to the control panel 21.

[0029] The testing mechanism includes a slide rail 15, a slider 16, a spring 17, and a displacement sensor 18. The slide rail 15 is fixedly installed on one of the two support plates 2, and the slide rail 15 corresponds to the output end of the hydraulic cylinder 6. Through the cooperative design between the motor 20, two transmission rollers 3, the conveyor belt 4, and multiple placement seats 5, the hydraulic cylinder 6 can be automatically and intermittently conveyed. Through the cooperative design between the fixing mechanism and the testing mechanism, not only can the hydraulic cylinder 6 be automatically limited and fixed, but it can also be automatically pressure tested. In summary, the hydraulic cylinder 6 can be pressure tested on a production line, which greatly improves convenience and efficiency.

[0030] In this embodiment, a slider 16 is slidably connected inside the slide rail 15, and a displacement sensor 18 is fixedly installed on one side of the slider 16. The displacement sensor 18 is connected to the control panel 21. The displacement sensor 18 can detect the extension distance of the output end of the hydraulic cylinder 6.

[0031] In this embodiment, a spring 17 is fixedly installed on one side of the slider 16. One end of the spring 17 is fixedly connected to the slide rail 15. The elastic potential energy of the spring 17 causes the slider 16 to push the output end of the hydraulic cylinder 6 to retract, and the slider 16 returns to its original state, and the output end of the hydraulic cylinder 6 retracts into the placement seat 5.

[0032] In this embodiment, the fixing mechanism includes a bracket 8, an electric push rod 9, a clamping plate 11, and a hydraulic pump 12. The same bracket 8 is fixedly connected to two support plates 2. An electric push rod 9 is fixedly installed on the bracket 8. An installation plate 10 is fixedly connected to the output end of the electric push rod 9. A clamping plate 11 is fixedly installed at the bottom of the installation plate 10. The clamping plate 11 is in contact with the hydraulic cylinder 6. Driven by the electric push rod 9, the installation plate 10 drives the clamping plate 11, the hydraulic pump 12, and the second quick connector 13 to move downward synchronously. This allows the clamping plate 11 and the support plate 19 to cooperate in clamping and limiting the hydraulic cylinder 6, while also ensuring a tight connection between the first quick connector 7 and the second quick connector 13.

[0033] In this embodiment, a hydraulic pump 12 is fixedly installed on the top of the mounting plate 10. The hydraulic pump 12 is sealed with a round pipe. One end of the round pipe passes through the mounting plate 10 and is sealed with a quick connector 13. The hydraulic pump 12 and the electric push rod 9 are both connected to the control panel 21. The hydraulic pump 12 drives the hydraulic oil in the oil tank 14 to the hydraulic cylinder 6, thereby causing the output end of the hydraulic cylinder 6 to extend and push the slider 16, thereby causing the slider 16 to compress the spring 17 and drive the displacement sensor 18 to move synchronously.

[0034] In this embodiment, one of the two connection ports on the hydraulic cylinder 6 is threaded with a quick connector 7. The quick connector 7 is compatible with the quick connector 13, which facilitates the pump 12 to deliver hydraulic oil into the hydraulic cylinder 6 and achieves the effect of quick assembly and disassembly.

[0035] In this embodiment, an oil tank 14 is fixedly installed on the top of the mounting plate 10. A delivery pipe is sealed and connected to the oil tank 14. One end of the delivery pipe is sealed and connected to the hydraulic pump 12 for storing hydraulic oil.

[0036] In this embodiment, a motor 20 is fixedly installed on one of the two support plates 2. The output end of the motor 20 is fixedly connected to one of the two transmission rollers 3 for driving the conveyor belt 4. The same support plate 19 is fixedly connected between the two support plates 2. The support plate 19 is in contact with the conveyor belt 4 to achieve the lifting effect and cooperates with the clamping plate 11. Multiple placement seats 5 are fixedly installed on the conveyor belt 4. The multiple placement seats 5 are all adapted to the hydraulic cylinder 6 to facilitate the conveyor belt 4 to transport the hydraulic cylinder 6 and play a certain limiting effect. The motor 20 is connected to the control panel 21.

[0037] Working principle: During use, the motor 20, liquid pump 12 and electric push rod 9 are controlled and driven through the control panel 21;

[0038] First, the hydraulic cylinder 6 that needs to be tested is placed in the placement seat 5, and the quick connector 1 7 is aligned with the quick connector 2 13. Then, the corresponding transmission roller 3 is intermittently driven by the motor 20, and under the cooperation between the two transmission rollers 3 and the conveyor belt 4, the conveyor belt 4 achieves the effect of intermittently conveying the hydraulic cylinder 6.

[0039] When the hydraulic cylinder 6 is delivered to the lower part of the clamping plate 11, the electric push rod 9 drives the mounting plate 10 to move the clamping plate 11, the hydraulic pump 12, and the second quick connector 13 downwards simultaneously. This allows the clamping plate 11 and the support plate 19 to cooperate in clamping and limiting the hydraulic cylinder 6, while simultaneously ensuring a tight connection between the first quick connector 7 and the second quick connector 13. Then, the hydraulic pump 12 drives the hydraulic oil in the oil tank 14 to be delivered into the hydraulic cylinder 6, causing the output end of the hydraulic cylinder 6 to extend and push the slider 16. This causes the slider 16 to compress the spring 17 and drive the displacement sensor 18 to move synchronously. During this process, the displacement sensor 18 can detect the extension distance of the output end of the hydraulic cylinder 6 and transmit the information to the control panel 21. At the same time, the control panel 21 compares the information with the preset value and judges whether the hydraulic cylinder 6 is qualified. If the hydraulic cylinder 6 is unqualified, the control panel 21 will remind the staff through an alarm.

[0040] Subsequently, the hydraulic oil in the hydraulic cylinder 6 is drawn into the oil tank 14 by the reverse drive of the hydraulic pump 12. During this process, the elastic potential energy of the spring 17 causes the slider 16 to push the output end of the hydraulic cylinder 6 to retract, and the slider 16 returns to its original shape, causing the output end of the hydraulic cylinder 6 to retract into the placement seat 5. Then, the reverse drive of the electric push rod 9 causes the clamping plate 11 and quick connector 2 13 to disengage from the hydraulic cylinder 6 and quick connector 1 7, respectively. In summary, the effect of pressure testing of a hydraulic cylinder 6 is achieved. Then, the above operation is repeated to achieve the effect of continuous pressure testing of the hydraulic cylinder 6, improving convenience and efficiency.

[0041] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, the hydraulic cylinder 6 can be subjected to assembly line pressure testing, which greatly improves convenience and efficiency. Moreover, the structure is simple and the practicality is higher.
