Device and method for rapidly detecting height from seat body big surface to conical surface measurement circle

Abstract

The invention discloses a device and a method for rapidly detecting the height from the seat body big surface to the conical surface measurement circle. The device comprises a cone matching with a conical surface in a seat body in size. The cone is provided with a measurement rod. A rapid detection mechanism comprises a covering body matching with the seat body big surface. An upper end surface of the covering body is of a stair structure. The stair height difference is set according to the tolerance of a measured dimension. The invention is accurate in detection, low in cost and fast in detection speed.

Description

technical field [0001] The invention relates to the technical field of water pump seat body detection equipment, in particular to a device for quickly detecting the height of a circle from a large surface of a seat body to a cone surface. Background technique [0002] The detection method of measuring the height of the circle from the large surface of the seat body to the cone surface, the general method is to design and manufacture a special pallet, and judge whether the size is qualified by judging whether the large surface of the pallet is firmly attached to the workpiece, but the judgment standard is vague and easy to misjudge; It can also be measured by three coordinates, but the high detection cost cannot realize online measurement. [0003] CN200910065484.7 application date 2009-07-21 discloses a method for measuring the distance between the large surface of the pump body and the conical surface and a special tool, and the dial indicator on the special tool is calibra...

Problems solved by technology

Another example is the 5th Henan Automotive Engineering Science and Technology Academic Conference, the method of measuring the height of the impeller circle, Jiang Huili, Wang Ruijin, the shortcomings of the above two are: 1) If the distance from the cone surface of the pump body to the large surface is greater than the standard height value , the measuring circle under the test body cannot be in contact with the cone surface of the pump body. At this time, the test body is in full contact with the large surface of the pump body, and the micrometer shows zero, but at this time the measuring circle under the test body is not in contact with the cone surface of the pump body. , the true value from the large surface of the seat body to the cone surface has not been measured, so the above device cannot detect unqualified products whose height from the cone surface to the large surface is greater than the standard height value

2) From the above device, it can be seen that the micrometer can only be set on the peripheral side of the inspection body and is in contact with the peripheral side of the pump body. If the height from the cone surface to the large surface is slightly lower than the standard height value, the inspection body is easy to tilt. At this time, one end of the inspection body In contact with the large surface of the pump body, the micrometer also shows zero at this time, but the above-mentioned device cannot detect that the product is unqualified
