Image measuring instrument on the method of measuring transparent and reflective workpieces
The method of image measuring instrument for measuring transparent and reflective workpieces. The image measuring instrument is a high-magnification optical microscope used to magnify and image the workpiece to be measured, and then the CCD system transmits the magnified image to the computer to generate a complete engineering drawing through computer software. The imager is such a measuring instrument, and the measured object will include the contour, size and angle of the workpiece. There are three types of automatic imagers at work, semi-automatic imagers and manual measurement imager principles. There are certain differences between them. The automatic image measuring instrument is an optical non-contact measuring instrument developed on the basis of the CNC imager. It has more powerful functions, higher precision and more convenient operation. As we all know, the image measuring instrument is an important measuring tool in today's industrial production. Different workpieces have different measurement methods and accurate measurement results. In workpiece measurement, we mainly measure products made of metal and plastic materials, but how to measure when encountering transparent or reflective products? When the instrument encounters transparent or reflective products, a slight modification is required. This is where we are confused. So how to measure the size and shape of these special parts? The first is that we need to improve the working principle of the image measuring instrument. When detecting a transparent workpiece, the light passing through the surface of the workpiece can be magnified and imaged. At this time, as long as the laser lens is added to the detection lens of the image measuring instrument, it can be used for deep zoom, edge search and complete surface refraction, and can measure the size and shape of the workpiece. Therefore, the glass lens of the mobile phone and the watch glass Transparent workpieces can detect the size and size of surface sand particles. There are many measuring instruments for image measurement, which should be selected and used according to different workpieces. It is important that the results of the image measuring instrument are accurate.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
