[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] 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.

[0026] This utility model proposes a device for testing the oil tightness of clamps, such as... Figures 1 to 5 As shown, a preferred embodiment of the clamp oil tightness testing device of this utility model includes: an oil tank (not shown in the figure), a pressurizing mechanism (not shown in the figure), an oil circuit 10, and a camera module 20.

[0027] The oil tank is used to store oil-soluble fluorescent leak detector. The oil tank is connected to the oil circuit 10. The clamp to be tested 30 is set on the oil circuit 10 and connected to the oil circuit 10. The pressurizing mechanism is used to pressurize and maintain the oil-soluble fluorescent leak detector in the oil circuit 10. The camera module 20 is set towards the clamp to be tested 30 and is used to photograph the leakage part of the clamp to be tested 30.

[0028] In this embodiment, the oil-soluble fluorescent leak detector in the oil tank is a mixture of aviation kerosene and fluorescent agent, and the volume ratio of aviation kerosene to fluorescent agent is 500:1.

[0029] The fluorescent agent is LUYOR-6100 oil-based fluorescent leak detector; the aviation kerosene is RP-3.

[0030] The light source wavelength of the camera module 20 is 365 nanometers.

[0031] This embodiment uses LUYOR-6100 oil-based fluorescent leak detector for leak detection, which is very simple. The detection process consists of two steps. The first step is to inject the oil-soluble fluorescent leak detector into the oil circuit 10 fluid system, start system circulation, and the oil-soluble fluorescent leak detector quickly dissolves and permeates into all leak points in the system with the fluid. This process takes about 5-10 minutes (depending on the type of oil and temperature). The second step is to irradiate the detection area with a high-intensity black light (invisible ultraviolet or infrared light). The leak will show a strong yellowish-white fluorescence, which is easily detected, especially suitable for micro-leaks. This fluorescence can be easily distinguished from the natural green fluorescence of ordinary oils.

[0032] This embodiment uses LUYOR-6100 oil-based fluorescent leak detector to test the oil tightness of clamps. Compared with existing detection methods such as visual inspection, air pressure testing, and soap foam testing, it can safely, efficiently, conveniently, and accurately detect all types of leaks, even the smallest ones, and at a very low cost.

[0033] Furthermore, in this embodiment, the oil circuit 10 includes a first electromagnetic ball valve 40, a second electromagnetic ball valve 50, a third electromagnetic ball valve 60, a fourth electromagnetic ball valve 70, a pressure gauge 80, a check valve 90, and a flow sensor 100.

[0034] One end of the first electromagnetic ball valve 40 is connected to the oil storage tank, and the other end is connected to the second electromagnetic ball valve 50, the pressure gauge 80 and one end of the clamp to be tested 30 through a four-way valve. The other end of the clamp to be tested 30 is connected to one end of the one-way valve 90 and one end of the fourth electromagnetic ball valve 70. The other end of the one-way valve 90 is connected to the third electromagnetic ball valve 60, and the other end of the fourth electromagnetic ball valve 70 is connected to the flow sensor 100.

[0035] In this embodiment, the flow sensor 100 can be used to detect whether air in the oil circuit 10 is discharged. Specifically, when the oil circuit 10 is pressurized, if the pressure of the flow sensor 100 changes and reaches the preset pressure value, it indicates that the oil-soluble fluorescent leak detection agent in the oil circuit 10 has passed through the fourth electromagnetic ball valve 70, and it can be determined that the air in the oil circuit 10 has been discharged.

[0036] In addition, the flow sensor 100 can also be used to detect whether the clamp 30 under test has a serious leak. If, during the pressurization phase, the flow sensor 100 fails to reach the preset pressure value within a preset time, it indicates that the clamp 30 under test has a serious leak.

[0037] Furthermore, in this embodiment, the clamp oil tightness testing device also includes a rotary drive mechanism for driving the clamp 30 under test to rotate.

[0038] When performing oil tightness testing on clamps, the clamp 30 under test is driven to rotate by the rotary drive mechanism, so that the camera module can capture and test the clamp 30 under test from 20360 degrees without blind spots, thereby improving the testing accuracy and avoiding missed detections.

[0039] Specifically, in this embodiment, the rotary drive mechanism includes a first rotary joint 110 and a second rotary joint 120 disposed on the oil circuit 10, as well as a first drive motor (not shown in the figure) and a second drive motor (not shown in the figure) for driving the first rotary joint 110 and the second rotary joint 120 to move and thereby drive the clamp 30 under test to rotate. The moving part of the first rotary joint 110 is connected to one end of the clamp 30 under test, and the moving part of the second rotary joint 120 is connected to the other end of the clamp 30 under test.

[0040] In this embodiment, the clamp oil tightness testing device further includes an X-axis motion module 130 and a Y-axis motion module 140. The camera module 20 is disposed on the Y-axis motion module 140, and the Y-axis motion module 140 is disposed on the X-axis motion module 130.

[0041] The preferred embodiment of the clamp oil tightness testing device of this utility model includes the following steps:

[0042] Step S10, Exhaust: Inject the oil-soluble fluorescent leak detector into the oil circuit fluid system, start the system circulation, open the first and fourth solenoid ball valves, close the second and third solenoid ball valves, and exhaust the air in the oil circuit.

[0043] Step S20, pressurization: Close the third solenoid ball valve and pressurize the oil circuit to the preset pressure through the pressurization mechanism;

[0044] Step S30, Pressure Holding Test: After a preset pressure holding time, the flow sensor is used to determine whether the clamp under test is leaking oil.

[0045] Step S40, depressurize: open the second, third and fourth solenoid ball valves, take a picture of the clamp under test through the camera module, and determine whether the clamp under test is leaking oil based on the picture results;

[0046] Step S50: Dry the oil passages.

[0047] In this embodiment, before step S10, the following steps are included: preparing an oil-soluble fluorescent leak detector, wherein the oil-soluble fluorescent leak detector is a mixture of aviation kerosene and a fluorescent agent, and the volume ratio of aviation kerosene to the fluorescent agent is 500:1; the fluorescent agent is LUYOR-6100 oil-based fluorescent leak detector; and the aviation kerosene is RP-3.

[0048] In summary, the beneficial effects of this utility model's clamp oil tightness testing device are:

[0049] This utility model, through the above-mentioned technical solution, includes: an oil storage tank, a pressurizing mechanism, an oil circuit, and a camera module; the oil storage tank is used to store oil-soluble fluorescent leak detector, the oil storage tank is connected to the oil circuit, the clamp to be tested is set on the oil circuit and connected to the oil circuit, the pressurizing mechanism is used to pressurize and maintain the pressure of the oil-soluble fluorescent leak detector in the oil circuit, and the camera module is set towards the clamp to be tested for photographing the leakage part of the clamp to be tested.
