[0024] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and not used to limit the scope of the utility model.
[0025] Embodiment
[0026] As Figure 1 shown, the hardness detection device of the plug valve of the embodiment comprises a rack 1, a plug valve transfer taking and placing device 2 and a hardness detection mechanism 3, the top of the rack 1 is provided with a table 11, the table 11 is provided with a rotating device 4, the rotating device 4 is provided with a bearing disc 41, the bearing disc 41 is provided with a positioning column 42 matched with the port of the plug valve, and the hardness detection mechanism 3 is installed on the upper part of the table 11 corresponding to the side of the rotating device 4.
[0027] The hardness detection device of the plug valve of the embodiment obtains the plug valve to be detected near the rack 1 through the plug valve transfer taking and placing device 2, and then moves to the bearing disc 41, and makes one end flange of the plug valve downward, and makes the corresponding through hole sleeve on the positioning column 42, so that the plug valve is "erected" on the bearing disc 41. During detection, the detection end of the hardness detection mechanism 3 contacts the surface of the plug valve to detect the hardness. During the process, the detection end is temporarily separated from the plug valve, and then the rotating device 4 is operated to rotate and adjust the angle of the plug valve, and then the hardness detection mechanism 3 is used for detection again to realize detection of multiple points in different directions. The whole device has reasonable structure design, can realize mechanical transfer of the plug valve, and can realize hardness detection during the transfer process, and improves the problems of no special tooling, high detection difficulty, high intensity and long time consumption in the traditional technology.
[0028] As a preferred embodiment, the plug valve transfer taking and placing device 2 comprises a first mechanical hand.
[0029] In the above embodiment, the first mechanical hand with clamping jaws is used to grab the plug valve near the rack 1, and then transfer it to the bearing disc 41 and sleeve it on the positioning column 42, and the operation is very intelligent.
[0030] It should be noted that: the mechanical hand is a commonly used intelligent robot, and the positioning, grabbing and placing actions are mature technologies (generally cooperating with a machine vision system for accurate positioning and placing), which will not be described here.
[0031] As a preferred embodiment, as Figure 2 shown, one side of the rack 1 is provided with an infeed flow line 5, and the other side is provided with an outfeed flow line 6.
[0032] In the above embodiment, the infeed flow line 5 and the outfeed flow line 6 are distributed on both sides of the rack 1, the plug valve transfer taking and placing device 2 can obtain the plug valve from the infeed flow line 5, place it on the bearing disc 41, and after detection, place it on the outfeed flow line 6 for conveying, so that the whole realizes flow line type operation, and the processing efficiency is higher.
[0033] In the embodiment, the rotating device 4 is a rotary support of a suitable type.
[0034] In the embodiment, the positioning column 42 is wrapped with a flexible wear-resistant layer. On the one hand, the flexible wear-resistant layer can play a certain protective role when the plug valve is inserted into the positioning column 42. On the other hand, the flexible wear-resistant layer can also compensate for the gap between the positioning column 42 and the flange hole of the end of the plug valve, so that the plug valve is more stable when it is inserted into the positioning column 42.
[0035] In the embodiment, the hardness detection mechanism 3 is an ultrasonic hardness detector of a suitable type.
[0036] As a preferred embodiment, the plug valve transfer and taking and placing device 2 is distributed on one side of the table top 11, the other side of the table top 11 is provided with the first lifting mechanism 7, the upper end of the first lifting mechanism 7 is provided with the telescopic mechanism 8, the main body of the ultrasonic hardness detector is arranged on the first lifting mechanism 7, and the detection end is arranged at the telescopic end of the telescopic mechanism 8. The telescopic mechanism 8 is used to drive the detection end of the ultrasonic hardness detector to horizontally extend or retract to approach or move away from the plug valve arranged on the positioning column 42.
[0037] In the embodiment, the plug valve transfer and taking and placing device 2 and the hardness detection mechanism are distributed on both sides of the table top 11 and do not affect each other. During detection, the first lifting mechanism 7 drives the telescopic mechanism 8 to ascend and descend to adjust the height (that is, to adjust the height of the detection end of the ultrasonic hardness detector), so that detection at different positions in the vertical direction is realized. The telescopic mechanism 8 drives the detection end to extend and contact the surface of the plug valve, so that effective detection of hardness is realized. After detection at each point is completed, the telescopic mechanism 8 is retracted to adjust to the next point (or the rotating device 4 drives the plug valve to rotate by a certain angle), and the telescopic mechanism 8 is extended again to contact and detect. After detection is completed, the first lifting mechanism 7 and the telescopic mechanism 8 are returned to move away from the plug valve, so that automatic detection is realized as a whole.
[0038] In the embodiment, the first lifting mechanism 7 is an electric linear module of a suitable type, and the telescopic mechanism 8 is an electric push rod of a suitable type. Both of them can be connected to a smart terminal to realize intelligent control.
[0039] Of course, in the embodiment, the first lifting mechanism 7 and the telescopic mechanism 8 can be replaced by a mechanical hand, that is, two mechanical hands are distributed on both sides of the table top 11, one is used to obtain the plug valve, and the other is used to drive the detection end of the ultrasonic hardness detector to contact different positions on the surface of the plug valve.
[0040] As a preferred embodiment, the second lifting mechanism 111 is arranged on the table top 11, the upper end of the second lifting mechanism 111 is connected with a cross beam 112 extending above the positioning column 42, the lower end of the cross beam 112 is rotatably arranged with a pressing disc 113, and the lower end of the pressing disc 113 is arranged with a limiting column 114 coaxially distributed with the positioning column 42.
[0041] In the embodiment, after the plug valve sleeve is placed on the bearing disc 41, the second lifting mechanism 111 drives the cross beam 112 to descend, so that the pressing disc 113 is pressed against the flange end on the upper end of the plug valve, and meanwhile, the limiting column 114 at the lower end of the pressing disc 113 is inserted into the hole on the upper end of the plug valve, thereby achieving good positioning of the upper and lower ends and ensuring that the plug valve is not displaced or tilted during detection.
[0042] In the embodiment, the second lifting mechanism 111 is an electric lifting column of a suitable model on the market and is intelligently controlled by connecting with a terminal.
