Three-dimensional shape measuring instrument

Abstract

The invention relates to a three-dimensional shape measuring instrument comprising a box body, a bottom plate fixedly arranged on the box body, a cross beam connected with the bottom plate, and a first support and a second support, wherein the first support and the second support are arranged at the two ends of the cross beam and used for holding an industrial camera, the cross beam is of a U shape and comprises a cross beam body, a first side edge and a second side edge, the first side edge and the second side edge are provided with rails, a first sliding block and a second sliding block arearranged on the two sides of the bottom plate; the first support and the second support are arranged on the cross beam through a connecting part, the first support and the second support can horizontally rotate relative to the cross beam. The three-dimensional shape measuring instrument is simple in structure, convenient to operate, and capable of realizing omni-directional shooting, adjusting thesupport angle, and timely discharging heat generated by the equipment.

Description

technical field [0001] The invention relates to a three-dimensional shape measuring instrument, which belongs to the technical field of three-dimensional shape measurement. Background technique [0002] Under the tide of modern high-tech industry development, the design and manufacture of industrial products have moved to a new level. With the rapid development of numerical control technology, the manufacturing process of industrial product parts is developing in the direction of high precision, high complex surface and large scale. How to use efficient, fast and accurate measurement methods to measure the process quality of product parts appears to be very important. [0003] At present, the quality measurement technology for the three-dimensional shape of product parts can be mainly divided into two categories: one is the contact measurement equipment in which the measurement probe (or sensor) is in direct contact with the surface of the measured object. For example, the...

[0005] The quasi-industrial three-dimensional shape measuring instrument is a kind of equipment that integrates a grating projector and an industrial camera. The grating projector and the camera are installed and fixed through the mounting base in the housing of the measuring instrument. The existing three-dimensional shape measuring instrument is due to The assembly method of the mounting base is very complicated, and the design of the measuring instrument itself has the following disadvantages in the actual application process: 1. To adjust the angle between the two cameras, the measuring instrument shell and the camera lens shell must be opened to adjust; 2. 1. To adjust the pitch angle of the grating projector, the housing of the measuring instrument and the housing of the camera lens must be opened to adjust; 3. The process of disassembly and reassembly is particularly cumbersome, and it is time-consuming and laborious to operate in the narrow space environment of the measuring instrument; in addition, the existing The design of the measuring instrument shell structure is not conducive to the heat dissipation of the equipment
