3. Probe measurement:
1. Working principle of stylus:
The stylus is an integral part of the measurement system. When the stylus head of the stylus contacts the workpiece, the change of the stylus head drives the probe mechanism to generate signals, and the measurement results are obtained after processing to achieve the purpose of detection.
2. Source of stylus measurement error
Ambient temperature and humidity, the stiffness of the stylus component material, the accuracy of the stylus head, the coaxiality of the stylus head and the stylus shank thread, the accuracy of the stylus shank thread, and the contact position of the stylus head and the workpiece.
It is recommended that the stylus should be calibrated during precision measurement, otherwise the measurement accuracy will be reduced.
3. The principle of stylus selection
3.1. The diameter of the measuring ball should be as large as possible to reduce the influence of the surface roughness of the tested workpiece on the detection result.
3.2. The stylus should be as short as possible. If the stylus is too short, the less bending or deformation, the higher the accuracy.
3.3. Minimize the joints. Each additional connection point increases a potential bending and deformation point.
3.4. Stylus connection form: threaded or straight shank connection
3.5. The basic mechanism of the spherical thread connecting the straight stylus: stylus head, stylus rod, stylus handle, extension rod, anti-collision protection seat, etc.
Probe measurement contains 2 menus, namely "probe measurement" and "3D auxiliary measurement".
The "probe measurement" menu is mainly used to perform a single measurement of an object, and contains the following commands:
Probe settings: Carry out some general settings of the probe, including probe calibration.
Horizontal line measurement: used to measure a straight line parallel to the horizontal plane.
Horizontal circle measurement: used to measure a circle parallel to the horizontal plane.
Spatial point measurement: used to measure any point in space, this command must set the datum plane.
Space line measurement: used to measure any straight line in space, this command must set the datum plane.
Space circle measurement: used to measure any circle in space, this command must set the datum plane.
Solution setting: It is used to set the compensation method of spatial points, lines and circles, such as whether to project to the reference plane and so on.
Height measurement: used to measure the distance of an object in the Z direction.
Plane measurement: Use a probe to take at least 3 points to fit a plane to obtain this
The flatness of the plane and other parameters.
Ball measurement: Use a probe to take at least 4 points to fit a sphere to obtain parameters such as the diameter of the sphere.
Cylinder measurement: Use the probe to take 6 points to fit a cylinder. This command must set the datum plane.
Cone measurement: Use the probe to take 6 points to fit a cone. This command must set the datum plane.
Behavioral tolerance measurement: flatness, parallelism, perpendicularity, inclination.
Remarks: The probe has automatic rebound protection and anti-collision function. The collision speed and rebound distance can be set according to the measurement requirements. The Yixin probe automatic measurement system can ensure the smoothness of the contact between the probe and the workpiece surface and ensure the stability and continuity of the measurement force, thereby improving the repeatability of the product. The automatic rebound function of the Z-axis probe can prevent strong impacts. , Improve the durability and reliability of the product.

14. The software can measure multi-deformation, groove shape, arc chamfering and virtual measurement.
15. The 2.5D measurement software can be upgraded, with functions: slope, height, sphere, cylindrical measurement, etc.
16. Re-measurement function: This function can re-change the measurement method, lighting, magnification, etc., for the elements that have been measured, and then refresh the measurement data, and the related element data will also be refreshed (such as: two-line construction distance, if If one of the lines is re-measured, the distance element data will also be refreshed).
17. Modify, edit and view edge seeking status: The software can modify and edit the edge seeking range, light source brightness, magnification, etc. of any measurement element. You can also view the edge-finding status of a certain element measured before (including the position of the edge-finding, the brightness of the light source used, the magnification and the original point taken, etc.), so that the user can control the status of the whole process of measurement.
4. Machine characteristics
The main body of the fuselage is made of high-precision natural granite, which has stable temperature characteristics and anti-aging deformation ability to ensure the stability of measurement and the accuracy of long-term use.
All Yixin's optical image measuring instruments are equipped with the F-1 high-precision full-closed-loop automatic zoom optical lens developed by our company as standard, with high performance and ultra-low distortion to ensure the accuracy of measurement.
High-precision fully closed loop automatic zoom optical lens
The principle of telecentric optics: adopting the optical design of parallel light path, the size of the object image will not change with the distance from the lens, causing the effect of perspective to produce additional measurement errors.
Automatic zoom optical telecentric lens (Telecentric), professionally manufactured by Yixin, is a lens specially designed to correct the parallax of traditional lenses. It can be within a certain object distance range, so that the image magnification will not vary with the object. The distance varies, which is a very important application when the measured object is not on the same surface.
The aperture is a device used to control the amount of light passing through the lens and entering the photosensitive surface of the body. Specifically, if the brightness is high, it can shrink to reduce the total amount of light passing through; on the contrary, if the light is very weak, it can be Make it larger to allow more light to enter. The larger the aperture, the smaller the depth of field; the smaller the aperture, the greater the depth of field. The farther the working distance, the greater the depth of field; the closer the working distance, the smaller the depth of field
At present, all the automatic machine EVM series have to do 2000 times of "burn-in measurement" before leaving the factory. We use a glass ruler to move the table in the four directions, X, 45 degrees, Y and 135 degrees. Repeat the direction measurement 500 times, a total of 2000 times, measuring a length of 180 mm, we will record all the measured data, the maximum and minimum size difference must be guaranteed to be within 2um before leaving the factory!
F1 High-precision, fully closed-loop, automatic zoom telecentric lens The features are as follows:
Adopt the high-precision, high-resolution ring-type grating ruler specially developed and designed by our company for F-1 for full closed-loop position feedback
High resolution, fully closed loop position feedback, avoiding the repetition error of image multiples caused by gear transmission gap, greatly improving the repeatability of the whole machine measurement.
The resolution of the ring grating is 20 times higher than that of the previous generation zoom lens.
Yixin telecentric lens VS non-telecentric lens
The use of non-telecentric lenses for imaging will produce perspective artifacts and bring test errors.
Use a telecentric lens to correct the image of the light source without distortion and improve the measurement accuracy.
