Description

Mounting plate suitable for positioning of various L-shaped probe calibration tables

Technical Field

The utility model belongs to the technical field of the probe calibration, specifically be a mounting panel that adapts to multiple L type probe calibration platform location.

Background

In flow field measurement and control, a pressure probe is generally adopted to measure parameters such as flow field pressure, velocity, direction and the like. In the measurement of an incoming flow of an impeller machine, a pipe, a wind tunnel, or the like, an L-shaped probe is most widely used. The L-shaped probe can extend into the flow field from the side surface, so that the disturbance to the flow field is reduced as much as possible, and more accurate pneumatic parameters of the flow field are obtained. After a pressure probe is produced, the pressure probe needs to be calibrated and calibrated before being put into use. Calibration wind tunnels are typically used to calibrate the probe.

When the pressure probe is calibrated, the wind tunnel is calibrated to give uniform and stable incoming flow, the probe head is given with a plurality of different deflection angles and pitch angles in the main flow area, pneumatic parameters under various angle states are collected, and a calibration file of the probe is obtained through calculation. The key points of the wind tunnel calibration of the probe are as follows: on one hand, the probe is arranged on the calibration platform, and the probe is ensured to be over against the incoming flow direction, and has zero deflection and zero pitching; on the other hand, since the aperture of the calibration wind tunnel is generally very small, it is necessary to ensure that the probe head is fixed at the center of the wind tunnel outlet as much as possible, and the position of the probe head end should be kept unchanged during the yaw and pitch movements of the probe.

The currently adopted tool is to clamp a probe in a middle circular hole of an electric turntable, and can refer to the figures shown in the attached

drawings

1 and 2, wherein 2 is an L-shaped probe to be calibrated; reference numeral 6 denotes a power-driven turntable, and therefore, when the L-shaped probe is mounted, the following problems occur: the length of the probe cannot be longer than the radius of the circular hole of the electric turntable, and the probe cannot be installed when the probe is not installed, so that the end part of the probe exceeds the position of the circle center of the electric turntable. And after the probe is installed, the parallel adjustment along the y direction shown in fig. 2 is inconvenient to realize, so that even if the length of the probe is smaller than the radius of the circular hole of the electric turntable, once the probe is changed into a probe with different probe lengths, the corresponding clamping block needs to be customized again to ensure that the probe is still located at the circle center position of the electric turntable, otherwise, during calibration, the pitching or deflecting motion of the probe cannot ensure that the probe is located at the center position of the outlet of the wind tunnel 1. When the probe head of the probe has machining deviation or the probe head of a special probe has offset along the z direction shown in fig. 2, the central lines of the probe head and the probe rod are not on the same plane, at this time, the probe head deviates from the central line of the wind tunnel outlet along the z direction shown in fig. 2, and the tool cannot perform translational adjustment on the probe head along the z direction.
