TECHNICAL FIELD
[0001] The utility model relates to nozzle detection technical field, and specifically is a full -automatic nozzle jet angle detection device. BACKGROUND
[0002] In the field of fluid control device processing, the machining precision of nozzle structure is directly related to the stability of fluid jet. The prior art has the following technical defects: due to the dynamic instability characteristics of fluid medium, when the size error occurs in the nozzle machining process, the actual angle of the jet water column will deviate from the design value, and the jet coverage range will produce deviation. The detection means currently adopted by the industry mainly exists two kinds of technical bottlenecks: the first kind adopts artificial visual detection method, and the operator measures the water column track through the scale, which has subjective judgment error and low detection precision; the second kind adopts flow metering device or laser scattering analyzer and other precision instruments, which can improve the detection precision, but need to configure a multi-sensor combined system, and the single detection time is as long as 3-5 minutes, and the equipment purchase cost is high. The above technical scheme is difficult to meet the industrial production demand in detection efficiency, equipment economy and operation convenience.
[0003] Therefore, it is urgent to design a full-automatic nozzle jet angle detection device. CONTENT OF THE UTILITY MODEL

[0015] In order to make the purpose, principle and structure of the utility model more clear and explicit, the following is further described in combination with the drawings and specific embodiments.
[0016] The specific implementation structure of the full-automatic nozzle spray angle detection device is as follows: referring to the accompanying drawings Figures 1-3 , the device main body comprises a nozzle 1, a nozzle detection plate 2, a displacement sensor 4 and a detection qualified display 5. The nozzle detection plate 2 is vertically arranged in front of the nozzle 1 in the jet direction through a support, and the distance between the two is L. The nozzle detection plate 2 is made of elastic metal sheet, one end of the nozzle detection plate 2 is fixed to the base through a bolt, and the other end of the nozzle detection plate 2 is a free end.
[0017] When the jet angle of the jet water column 3 sprayed by the nozzle to be detected 1 is within 20°, the nozzle to be detected 1 is qualified, and if the angle exceeds the angle, the impact force of the jet water column 3 sprayed by the nozzle to be detected 1 will decrease, and the effect of high-pressure cleaning cannot be achieved, that is, unqualified.
[0018] Based on this, a through hole 7 is arranged in the center of the nozzle detection plate 2, the diameter of the inscribed circle in the through hole 7 is D, and D is calculated and determined according to the formula D=2*tan(A / 2)*L, wherein A is a preset qualified jet angle. In the embodiment, the preset qualified jet angle A is preferably 20°.
[0019] The shape of the through hole 7 can be selected as circular, triangular, polygonal, or irregular, depending on actual needs. In this embodiment, a circular shape is preferred. When the water jet 3 from the qualified nozzle 1 passes through the inscribed circle of the through hole 7, it can pass through completely unobstructed.
[0020] The displacement sensor 4 is installed on the free end of the nozzle detection plate 2 on the side facing away from the nozzle 1. Its sensing end maintains a gap with the surface of the nozzle detection plate 2, and the projection area of the sensing end is present at the edge of the through hole 7 to avoid water mist interference.
[0021] The spray angle of nozzle 1 affects the projected area of the water jet 3 on nozzle detection plate 2. By detecting whether the projected area of the water jet 3 on nozzle detection plate 2 at the same distance between the nozzle 1 and the nozzle detection plate 2 exceeds the preset qualified projected area, it can be determined whether the spray angle of the nozzle 1 is qualified. The projected area of the water jet 3 on nozzle detection plate 2 can be obtained by detecting the amount of water jet 3 passing through the through hole 7. If the nozzle 1 produces a diffusion area 6 that exceeds the qualified nozzle, causing excess water jet 3 to spray onto nozzle detection plate 2, the displacement sensor 4 can be used to detect the deformation of nozzle detection plate 2 under force to monitor the situation.
[0022] Specifically:
[0023] See Figure 1 , Figure 3 In (a) of the test, high-pressure water flows through nozzle 1 to form a conical jet of water 3. If the angle of the jet of water 3 from the nozzle under test is ≤20°, it is qualified. At this time, the jet of water 3 from the nozzle under test completely passes through the through hole 7 and does not contact the nozzle detection plate 2. The displacement sensor 4 has no signal output, and the green light on the display 5 indicates that the test is qualified.
[0024] See Figure 2 , Figure 3 In (b), if the water column diffusion angle exceeds the standard, such as >20°, then the nozzle 1 to be tested is unqualified. The water column 3 impacts the edge area of the nozzle detection plate 2, forming a diffusion area 6 that exceeds the qualified nozzle. The impact force of the diffusion area 6 that exceeds the qualified nozzle acts on the nozzle detection plate 2, causing the nozzle detection plate 2 to deform and displace. The displacement sensor 4 captures the displacement in real time and triggers the red light alarm of the qualified display 5.
[0025] This embodiment utilizes the synergistic effect of the geometric parameters of the through hole 7 and the displacement sensor to convert angle detection into a quantifiable mechanical deformation signal, thereby achieving fully automatic judgment and effectively avoiding human visual error.
[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and novel concept of this utility model, should be included within the protection scope of this utility model.
