Projection device convenient for adjusting object position for three-dimensional optical measurement

Abstract

The invention relates to the technical field of measurement projectors, in particular to a three-dimensional optical measurement projection device facilitating object position adjustment, which comprises a main body mechanism, and a fixing mechanism is mounted on the main body mechanism in a matched manner; the main body mechanism is connected with an adjusting mechanism; the adjusting mechanism is connected with a supporting mechanism in a matched mode. A lubricating mechanism is mounted in the supporting mechanism; the main body mechanism is connected with a limiting mechanism; the adjusting mechanism is rotated to conveniently adjust an object needing to be measured on the supporting mechanism, the supporting mechanism is rotated to adjust the placement position of the object, and the lubricating mechanism is used for oiling and lubricating components in the supporting mechanism, so that the sliding effect of the device is improved; when an operator needs to overhaul internal components of the device, the limiting mechanism can be pressed, so that the limiting mechanism slides in the main body mechanism, the main body mechanism is convenient to disassemble, and the stability of the main body mechanism is improved while the measurement projector is convenient to overhaul to a certain extent.

Description

technical field [0001] The invention relates to the technical field of measurement projectors, in particular to a projection device for three-dimensional optical measurement that is convenient for adjusting the position of objects. Background technique [0002] Measuring projector, also known as optical projection measuring instrument or optical projection comparator, is a measuring instrument that uses the principle of optical projection to project the outline or surface of the measured workpiece onto the observation screen for measurement or comparison. It can efficiently detect the contour and surface shape of workpieces with various complex shapes. In 3D optical measurement, the operator usually uses a measurement projector to measure the object. [0003] However, when measuring an object, the operator needs to make multiple adjustments to the position of the object. Because the general measurement projector may be slow in adjusting the level and aligning the object to ...

Problems solved by technology

[0003] However, when measuring an object, the operator needs to make multiple adjustments to the position of the object. Because the general measurement projector may be slow in adjusting the level and aligning the object to be detected, it is easy to affect the detection accuracy of the projector. and efficiency; moreover, when the device adjusts the position of the object, its internal components need to slide. After long-term use, the sliding effect will easily deteriorate, which is not conducive to improving the use efficiency of the device; It needs to be installed and disassembled, which is time-consuming and laborious, and to a certain extent is not conducive to improving the speed of maintenance of operators
