4 results about "Size measurement" patented technology

This invention provides a size measuring device, relating to the field of size detection technology. In this invention, a first laser probe measures a first vertical distance between itself and the side of the target object extending along a first horizontal direction; a second laser probe measures a second vertical distance between itself and the side of the target object extending along a second horizontal direction; and a third laser probe measures a third vertical distance between itself and the upper surface of the target object. A calculation unit is connected to the first, second, and third laser probes and receives measurement data from them to calculate the length, width, and thickness of the target object. This technical solution, through the cooperation of the laser probes and the calculation unit, measures the target object. Compared with traditional manual measurement, this device improves the accuracy of size measurement and reduces measurement errors.

The invention relates to detection equipment, and discloses size measurement equipment and a size measurement method thereof. A size measurement device comprises a detection area, a first line laser profile measuring instrument, a second line laser profile measuring instrument, a first visual detection assembly, a second visual detection assembly, a mounting seat and a positioning reference visual detection assembly. And the first line laser profile measuring instrument is arranged at the top of the detection area and reciprocates along the X axis, the Y axis and the Z axis of the detection area, and a light beam of the first line laser profile measuring instrument irradiates in the direction in which an inclined angle is formed between the light beam and the plane of the detection area. The second line laser profile measuring instrument is arranged on the side of the first line laser profile measuring instrument, performs Y-axis and Z-axis repeated movement along with the first line laser profile measuring instrument along the detection area, and performs X-axis movement along the direction of the first line laser profile measuring instrument; and the irradiation direction of the second line laser profile measuring instrument is opposite to or back to the irradiation direction of the first line laser profile measuring instrument.

The invention discloses a dimension measuring device, and relates to the technical field of dimension measurement, the dimension measuring device comprises a machine table, a positioning piece, a fixing piece and a measuring piece, a positioning groove is formed in the positioning piece, the positioning groove is used for being in positioning fit with a to-be-measured product, the fixing piece is used for fixing the to-be-measured product, and the measuring piece is used for measuring the dimension of the to-be-measured product. The positioning piece and the fixing piece are arranged in a relatively movable manner, so that the to-be-measured product can be separated from the positioning groove after being positioned, and the measuring piece is mounted on the machine table and is used for measuring the size of the to-be-measured product. The technical scheme provided by the invention aims to improve the efficiency of measuring the size of the special-shaped product.

The invention discloses a method for measuring the shape and position dimensions of a short arc complex part, and relates to the technical field of part measurement. Comprising the following steps: determining a first reference surface, a first reference element and a second reference element according to clamping and positioning of a part in each process; the first reference surface is determined through a first reference element and a second reference element; determining a Z-axis direction, an X or Y-axis direction and a coordinate origin of a coordinate system according to the first reference surface, the first reference element and the second reference element, and establishing a measurement coordinate system; the coordinate origin of the measurement coordinate system is translated to the theoretical position of the center point of the outer arc, the circle center position of the fitted outer arc and the coordinate system direction are obtained, and a new fitted coordinate system is formed; and measuring the size of the part according to the new fitting coordinate system. The problem that the size of a short-arc complex part cannot be accurately measured in the prior art is solved.
