Surface
Field of the Invention
The utility model belongs to dry-type cutting surface detection field, in
particular to a machine vision in-situ detection platform facing toward a cutting
surface.
Background of the Invention
The service life and performance of parts may be seriously affected by the
microscopic surface roughness during machining. Therefore, an image detection
o platform can be used for collecting images of the machined surface and further
analyze the physical, chemical and mechanical property, so as to ensure the
quality stability of parts and improve the production process. Meanwhile, with
the increase of machining automation, spot check on the machined surface
quality of parts has been changed into mandatory inspection. Therefore, how to
is collect surface images with a suitable detection platform during production is
getting more and more attentions. On the one hand, it is obviously that off-line
image detection cannot meet the requirement for high automatic production
efficiency of factories, on the other hand, though many scholars have studied the
in-situ collection with detection platform designed by machine vision
technology, there is still a requirement for the experimental collection conditions,
the efficiency is relatively low, the potential problems during actual application
are not considered, for most studies, only the horizontal surface collection during the in-situ collection is considered, and the detection requirement for vertical surface and curve in production process is often neglected. Therefore, a machine vision surface in-situ detection platform in small volume and convenient for carry and use shall be designed and established to meet the high automatic production efficiency and actual production requirements.
Content of the Utility Model
To solve the problems in the prior art, this application provides the
following technical scheme:
A machine vision in-situ detection platform facing toward a cutting surface
o comprises a ball screw gantry-type four-axis electric sliding table which is
connected with the worm gear electric rotating table through connecting plates.
The worm gear electric rotating table is connected with the camera clamp
adjusting device through connecting plates. The camera clamp adjusting device
is provided with the photographing device through connecting plates.
Further, the ball screw gantry-type four-axis electric sliding table comprises
four ball screw electric linear sliding tables which are respectively an X1-axis
ball screw electric linear sliding table, an X2-axis ball screw electric linear
sliding table, a Y-axis ball screw electric linear sliding table and a Z-axis ball
screw electric linear sliding table. Each ball screw electric linear sliding table
comprises a motor, a base, a bearing, a bearing fixing seat, a ball screw, a linear
guide rail, a dust cover, a sliding block and a U-type optoelectronic switch.
Further, the X1-axis ball screw electric linear sliding table and the X2-axis ball screw electric linear sliding table are arranged at intervals in parallel, with the sliding blocks being fixedly connected with connecting plates arranged in parallel and vertically. The top ends of connecting plates are fixedly connected with both ends of the Y-axis ball screw electric linear sliding table. The sliding block on the Y-axis ball screw electric linear sliding table is fixedly connected with the Z-axis ball screw electric linear sliding table through connecting plates.
Further, the Z-axis ball screw electric linear sliding table also comprises a
synchronous conveyor belt so that motors can drive the sliding tables to motion.
Compared with the prior art, this application has the following
o advantageous effects:
To be suitable for various working environments, the length, height and
width of the detection platform in the utility model can be adjusted and set
according to the internal size of different workbenches in different machine tools.
Besides, the operation accuracy of platform can be 0.1mm. Compared with other
platforms that clamp camera and lens with a manipulator for image detection,
the detection platform has the advantages of simple structure, flexible motion,
low cost, convenient carrying and high efficiency.
Compared with similar machine vision detection platforms, on the one
hand, the motion of motors is controlled by a computer in the utility model, so
that the photographing device can realize free 3D motion, detect surface images
without the need of workpiece removal from machine tool, meet the in-situ
detection requirements of machined surface and reduce the machining time of workpieces. On the other hand, the detection platform can realize 3D curve motion and rotary motion, not only detecting the images of horizontal surface, but also detecting the vertical surfaces and curves, which greatly meets the automatic production requirements during actual application.
