Embodiment Construction
[0017] The present invention will be further described below in conjunction with accompanying drawing.
[0018] Such as Figure 1 to Figure 4 As shown, the present invention includes a flange cover 1, a mandrel 2, a sliding gasket 3, a left bracket 4, a right bracket 5, a bracket upper plate 6, a bracket lower plate 7, a convex dovetail groove 8, a concave dovetail groove 9, Left fixed baffle 10, right fixed baffle 11, probe 12, lead screw 13, spur gear 14, major axis shaft frame 15, major axis 16, minor axis 17, bevel gear 18, nut 19, pointer 20, Dial 21, rotating nut 22, handle 23, rocking handle 24 and crank 25.
[0019] The center of the flange cover 1 is provided with a through hole for installing the mandrel 2, and the inner wall of the through hole is processed with two circles of grooves for installing an O-ring, so that the mandrel 2 and the flange cover 1 are airtightly connected. The lower surface of the flange cover 1 is processed with a circle of threaded holes ...

The invention discloses a probe moving mechanism, comprising a mandrel inserted into a flange cover, a handle is fixed on the mandrel, a long shaft is arranged in the center of the mandrel in a penetrating mode, a crank is fixed on the long shaft, and a support is arranged on the outer side of the long shaft; the top of the support is connected with a convex dovetail groove, the bottom of the support is connected with the upper surface of the mandrel, and the side surface of the support is connected with a short shaft; a pair of meshed bevel gears is fixed on one side of the short shaft and atthe top of the long shaft; a screw rod is arranged above the convex dovetail groove, one side of the screw rod and the other side of the short shaft are connected with a pair of meshed straight gears, and the screw rod penetrates through a concave dovetail groove; the concave dovetail groove is matched with the convex dovetail groove, and a probe is fixed at the top of the concave dovetail groove. The probe moving mechanism in the invention is simple in overall structure and convenient to operate; the crank and the handle are rotated so that radial and circumferential adjustment of the probecan be completed outside a cabin body, and further, the flow intensity of any point in the plane is measured; and a pointer is matched with a dial so that the adjustment of the probe is more accurateand the experimental data is more accurate.
Description
technical field [0001] The invention relates to a moving mechanism, in particular to a probe moving mechanism. Background technique [0002] As the spray control becomes more and more precise, the control of the spray shape, particle size, speed and flow intensity is getting higher and higher. In normal pressure, that is, in the atmospheric environment, the fluid can be collected for a certain period of time through the collection method, etc., and the flow intensity can be obtained through subsequent calculation. But in actual use, that is, the real environment is under the back pressure environment. In order to simulate the real environment, the processing back pressure test chamber is usually used to simulate, and the probe is used to measure the flow intensity in the back pressure test chamber. This simulation brings a new The problem is that compared with the measurement in the atmospheric environment, it is difficult to adjust the probe when carrying out the flow inte...
