[0028] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.
[0029] like Figure 1 As shown, this application proposes an oil valve testing device, which includes a workbench 1. The workbench 1 is equipped with a testing module 2 and a feeding module 3. The testing module 2 is used to perform air tightness testing and flow rate testing on the oil valves respectively. The feeding module 3 feeds qualified products and defective products separately according to the testing results.
[0030] like Figure 1-2 As shown, the detection module 2 includes a support frame 21 mounted on the workbench 1, a rotatable turntable 22 mounted on the support frame 21, and a first rotation drive component 23 that drives the turntable 22. The rotation plane of the turntable 22 is perpendicular to the workbench 1. Multiple material loading components 24 are evenly spaced along the circumference of the turntable 22, and a feeding station, an airtightness detection station, a flow rate detection station, and a transfer station are arranged sequentially around the turntable 22.
[0031] like Figure 1-2As shown, the material loading assembly 24 includes a material loading fixture 241 for accommodating the oil valve and a clamping member that cooperates to confine the oil valve within the material loading fixture 241. The material loading fixture 241 has an accommodating groove with one end open. The discharge port of the accommodating groove is disposed opposite to the center of the turntable 22. The accommodating groove is configured to conform to the outer contour of the oil valve. The oil valve is held in the accommodating groove, and the clamping member is used to clamp and confine the oil valve within the accommodating groove.
[0032] Specifically, the clamping component includes a laterally movable clamping rod 242 and a clamping cylinder 243 that drives the clamping rod 242. The clamping cylinder 243 drives the clamping rod 242 to move laterally along the radial direction of the material-carrying fixture 241, so that the clamping rod 242 is stopped at the opening of the receiving groove. The clamping rod 242 abuts against the oil valve in the receiving groove to prevent the oil valve from falling out of the receiving groove during rotation.
[0033] like Figure 1-2 As shown, the loading station is equipped with a loading assembly 25, which includes a feeding suction cup 251 and a loading cylinder 252 that drives it to move closer to and further away from the loading fixture 241. The movement path of the feeding suction cup 251 is coaxially aligned with the receiving groove. An external robot grabs the oil valve and delivers it to the feeding suction cup 251. After the feeding suction cup 251 is ventilated, it sucks up the oil valve. After the loading fixture 241 rotates to a position coaxial with the feeding suction cup 251, the loading cylinder 252 drives the feeding suction cup 251 to move closer to the loading fixture 241 and press the oil valve into the receiving groove. The feeding suction cup 251 is de-ventilated, leaving the oil valve in the receiving groove. The clamping cylinder 243 drives the clamping rod 242 to move laterally, confining the oil valve within the receiving groove.
[0034] like Figure 1-2 As shown, the airtightness testing station is equipped with an airtightness testing component 26. The airtightness testing component 26 includes an airtightness pressure plate 261 that can move laterally and a clamping cylinder 262 that drives the airtightness pressure plate 261. The airtightness pressure plate 261 is provided with an air inlet channel and an air outlet channel. The air inlet channel is connected to an external air inlet pipe, and the air outlet channel is connected to an air outlet pipe with a pressure sensor. A sealing ring is provided on the end face of the airtightness pressure plate 261 facing the material carrier fixture. When the clamping cylinder 262 drives the airtightness pressure plate 261 to press against the material carrier fixture 241, a closed air chamber is formed, which connects to the internal channel of the oil valve.
[0035] Preferably, in a specific embodiment, the airtightness detection component 26 is further provided with a pressure holding control unit, which is used to monitor the pressure change value of the venting pipeline within a preset pressure holding time.
[0036] like Figure 1-2As shown, the flow monitoring station is equipped with a flow detection component 27. The flow detection component 27 includes a flow pressure plate 271 that can be laterally pressed against the inlet end of the oil valve, a delivery cylinder 272 that drives the flow pressure plate 271, a flow receiver 273 that can be laterally pressed against the outlet end of the oil valve, and a receiving cylinder 274 that drives the flow receiver 273. The flow pressure plate 271 and the flow receiver 273 are respectively equipped with flow meters to monitor the inlet and outlet flow rates. When the delivery cylinder 272 and the receiving cylinder 274 operate synchronously, a closed liquid passage is formed through the oil valve.
[0037] Specifically, the flow pressure plate 271 is provided with a liquid inlet, which is connected to a constant pressure liquid source through a pipeline; the flow receiver 273 is provided with a liquid outlet, which is connected to a liquid collector through a pipeline, and the liquid collector is connected to a weighing sensor or a volumetric meter.
[0038] like Figure 1-2 As shown, preferably, in this embodiment, the flow detection assembly 27 further includes a lateral clamping member 275, which includes a laterally movable lateral pressure plate 2751 and a lateral pressure cylinder 2752 that drives the lateral pressure plate 2751. The lateral clamping member 275 is disposed opposite to the opening of the material loading fixture 241. The lateral pressure cylinder 2752 drives the lateral pressure plate 2751 to move closer to and further away from the material loading fixture 241, so as to ensure that the valve body can be tightly engaged in the material loading fixture 241 in a horizontal position. Preferably, the pressing surface of the lateral pressure plate 2751 is provided with a buffer pad to prevent squeezing damage to the oil valve.
[0039] like Figure 1-3 As shown, the transfer station is equipped with a transfer assembly 28, which is used to transfer the oil valve that has completed testing to the unloading module 3. The transfer assembly 28 includes a liftable receiving fixture 281, a lifting cylinder 282 that drives the receiving fixture 281 to move up and down, and a lateral movement drive module 283 that drives the lifting cylinder 282 to move laterally. The lifting path of the receiving fixture 281 driven by the lifting cylinder 282 is coaxially arranged with the loading fixture 241.
[0040] In a specific embodiment, the number of material loading components 24 on the turntable 22 is 4 sets, wherein the material loading station coincides with the airtightness detection station and is diagonally distributed with the transfer station at 180°, and the transfer station is located directly below the turntable 22.
[0041] Specifically, the loading fixture 241 can be rotated to be directly above the transfer component 28. After the oil valve completes the above-mentioned detection, the clamping part retracts, and the oil valve falls freely onto the receiving fixture 281. The lifting cylinder 282 drives the receiving fixture 281 to descend, so as to drive the oil valve on the receiving fixture 281 to descend synchronously until the oil valve is completely disengaged from the loading fixture 241. The transverse drive module 283 drives the receiving fixture 281 to move laterally to the unloading module 3.
[0042] like Figure 1-2 As shown, the unloading module 3 includes an unloading robot 31 and a first material tray 32 and a second material tray 33 located on the side of the unloading robot 31. The unloading robot 31 takes out the oil valve that has completed the test from the unloading end of the transfer component 28, and places qualified products and defective products into the first material tray 32 and the second material tray 33 respectively according to the test results.
[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
