Description

Profile tolerance measuring and checking fixture

Technical Field

The utility model belongs to profile tolerance measurement field especially relates to an utensil is examined in profile tolerance measurement.

Background

The main index for describing the dimensional accuracy of the curved surface is the profile tolerance error, which refers to the variation of the measured actual profile relative to the ideal profile. With or without a reference. The "profile degree" refers to a variation of the measured actual profile from the ideal profile. This concept is used to describe the accuracy of a curved or curvilinear shape.

The machining precision of the free-form surface is measured by the profile degree of the free-form surface, and is a geometric element which is difficult to define, and unlike general regular geometric elements, the machining precision of the free-form surface can be accurately defined by a small number of parameters, so that the inspection of the machining precision of the free-form surface is complicated, and the inspection is mainly characterized in that the measured surface cannot be directly used as a measurement reference, so that a measurement result contains systematic errors caused by the fact that a measurement coordinate system is not coincident with a design coordinate system.

In the application number: CN201320659337.4, having the filing date of 20131025 names: in the patent of a profile tolerance checking tool, the profile tolerance checking tool comprises a bottom plate, wherein a vertical plate is vertically arranged on the bottom plate, a standard block is arranged on the vertical plate through a positioning shaft, and a sample to be detected is fixed outside the standard block through a locking nut of the positioning shaft; a linear slide rail is arranged on the bottom plate corresponding to the vertical plate, a meter rack is fixed on the linear slide rail, and the meter rack is movably connected with a reading meter; the standard block is provided with a plurality of limiting holes and a vertical plate for limiting through limiting pins; the standard block and the sample to be measured are also positioned by the positioning pin. The utility model can detect the sample to be detected by positioning the standard block and arranging the sample to be detected in parallel and moving the linear slide rail, and has simple structure, economy and applicability; the standard block can be limited on the vertical plate by the aid of the limiting pin, and the position of the standard block is adjusted to ensure accurate measurement; the positioning pin is arranged to ensure the consistency of the standard block and the sample to be measured and also ensure the measurement precision of the standard block and the sample to be measured.

Disclosure of Invention
