Embodiment Construction

[0059] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0060] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0061] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indic...

Abstract

The invention discloses a square rod size measuring device and a square rod size measuring method, relates to the technical field of measurement, and aims to solve the problems of large square rod size error and large measurement difference in manual measurement. The square rod dimension measuring device comprises a support assembly; a bearing assembly which is arranged on the support assembly and used for bearing the square rod; an arc measuring assembly which is arranged on the support assembly and comprises at least one pair of distance sensor sets, and two distance sensors of each pair of distance sensor sets are located outside the two symmetrically-arranged arc faces of the square rod respectively, the distance measuring directions of the two distance sensors of each pair of distance sensor groups are coaxially and reversely arranged and are parallel to the diagonal line of the cross section of the square rod, each pair of distance sensor groups can move relative to the square rod in the axial direction perpendicular to the square rod, and the distance measuring direction of each pair of distance sensor groups is perpendicular to the moving direction of the pair of distance sensor groups, the device is used for measuring the diameter of the arc surface and the arc length projection size of the arc surface. According to the square rod measuring method, the square rod size measuring device is adopted for measurement.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a square bar size measuring device and a measuring method. Background technique [0002] In the process of crystal ingot processing, it is necessary to measure the appearance size of the ingot many times. The ingot can be divided into round rod and square rod. The round rod refers to the cylindrical rod after the drawn original crystal rod has been cut and rolled. . The square bar refers to the square bar after the original ingot has been cut and rolled and polished, and the four edges of the square bar are transitioned through arc surfaces. [0003] For the measurement of the appearance size of the round rod including diameter and length, CN204831203U discloses a measurement device for a single crystal rod, which is realized by three laser ranging sensors located on three quarter points of the same circle to measure the single crystal rod The measurement of the section dia...
