Water pump water seal height detection device and detection method thereof

Abstract

The invention discloses a water pump water seal height detection device, which comprises a measurement mechanism and a correction mechanism, wherein the measurement mechanism comprises a holding tube and a dial indicator; the holding tube is internally provided with a first tube cavity and a second tube cavity; the tube diameter of the first tube cavity is larger than that of the second tube cavity; the testing head of the dial indicator is fixed in the second tube cavity; the first tube cavity is internally provided with a moving rod; one end of the moving rod reaches a top rod extending inside the second tube cavity to be contacted with the testing head of the dial indicator; and the correction mechanism comprises a step-shaped correction block. By adopting the structure and the method, the device and the method of the invention have the following advantages that a detection tool is positioned by adopting a shaft core, the contact area between the measurement block and the water seal surface is added, and the possibility that the detection tool tilts in the measurement process is reduced; and in the case of detection, the swinging scale of the dial indicator can be directly viewed straightly, and data can be intuitively, accurately and quickly read.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a water pump water seal height detection device and a detection method thereof. Background technique [0002] During the assembly process of the water pump, the height of the water seal after assembly needs to be tested to avoid products with quality defects from leaving the factory. [0003] At present, the working height of the water seal after assembly is generally detected by vernier calipers and depth gauges. Vernier calipers and depth gauges are common measuring tools, which are easy to detect, but they are also deficient. For example, during the measurement process of the vernier caliper and the depth gauge, the contact area with the surface of the water seal is small, and the vernier caliper and the depth gauge are tilted due to uneven force, and the measurement result is incorrect. Using vernier calipers and depth gauges to measure is not easy to measure. Every tim...

For example, during the measurement process of the vernier caliper and depth gauge, the contact area with the water seal surface is small, and the vernier caliper and depth gauge are tilted due to uneven force, and the measurement result is incorrect.

Use vernier calipers and depth gauges to measure, it is not easy to measure, each time you need to pre-tighten the bolts and then pick up the degree, the operation process is cumbersome
