Gear measurement center non-contact measuring device

Abstract

The invention relates to the technical field of a gear measurement center. A non-contact measuring device comprises an optical signal emitter, a measurement platform, a lift device and a base. The lift device is arranged on the base; the lift device is provided with an H-shaped lifting slide block; the optical signal emitter is connected with the lifting slide block through a bolt; the measurement platform is arranged at the front side of the lift device; the measurement platform is provided with a protection frame; the protection frame is fixedly arranged on the measurement platform through bolts; the protection frame is equipped with a fiber measuring plate at the place of a square through hole in the middle of the protection frame; and the protection frame above the fiber measuring plate is provided with a transparent glass plate. The non-contact measuring device can realize geometric parameter measurement of gear contour innovatively by utilizing optical fibers; through non-contact measurement, the measurement result is allowed to be more accurate, and the gear tooling process before conventional contact measurement is saved; and contour point data is obtained directly, and such mode is more convenient than an image processing mode.

Description

technical field [0001] The invention relates to the technical field of gear measurement centers, in particular to a non-contact measurement device for a gear measurement center. Background technique [0002] The equipment of the gear measurement center is the equipment that can measure various shapes of spur gears and helical gears. Measuring gear hobs, worm gear hobs, shaving knives, radial shaving knives, gear shaper knives and other gear tools. It can also measure workpieces such as worm gears, worm straight bevel gears, helical bevel gears, and cams. It can be widely used in scientific research departments and factory measurement rooms such as automobiles, machine tools, instruments, aviation, aerospace, and national defense industries. [0003] The measurement of gears in existing gear measurement centers is mostly contact measurement. For example, the gear measurement centers produced by WENZEL Company in Germany, M&M Company in the United States, Haliang Company in...

Problems solved by technology

Although many measuring instrument companies have produced some new image measuring instruments for non-contact measurement, they all use CCD for non-contact measurement of gear profile image acquisition, and image processing is also used in the later stage of measurement The software performs complex image processing, such as using MATLAB to blur the image, etc.
