Description

Two-dimensional measurement leaning angle and device

Technical Field

Background

The secondary element measuring device is used for measuring the two-dimensional plane size of the product. When a secondary measuring device is used for measuring a product, a virtual measuring space containing coordinate systems of an X axis and a Y axis is usually required to be determined on a workbench of the measuring device, and the coordinate systems in the virtual measuring space are not a physical coordinate system, so that the positions of the virtual X axis and the Y axis are difficult to determine on the workbench by naked eyes, and therefore, the positions of the product to be measured or a mold are required to be adjusted for a plurality of times according to the position information of the product to be measured displayed on a measuring instrument, so that the edges of the product to be measured can be positioned on the X axis and the Y axis. However, the position of the tested product is adjusted on the workbench for a plurality of times, on one hand, the surface of the workbench is easy to scratch the tested product, so that the tested product is worn; on the other hand, the operation of multiple adjustment also reduces the working efficiency of the two-dimensional measurement.

Currently, the prior art mainly uses two-dimensional measurement of the leaning angle to solve the above problems. For example, chinese patent CN205192383U discloses a two-dimensional measuring angle leaning jig and chinese patent CN215572583U discloses a measuring angle leaning jig. However, the leaning blocks on the measurement leaning angles are usually not movable in the prior art, and because different product measurement points are different, some product measurement points overlap with the leaning block positions on the measurement leaning angles, so that when the secondary element measurement device grabs the product measurement points, the situations that the measurement points cannot be grabbed or the measurement points are grabbed incorrectly exist, and finally the measurement precision is reduced.

Therefore, how to make the secondary measurement angle not affect the measurement accuracy is a technical problem to be solved.
