Tool microscope use and maintenance
The structure of the tool microscope
1. Small tool microscope.
It is composed of a precision cross-moving table and an observation microscope. It is a small tool microscope. It is designed for ease of use, so the pillars will not tilt, and the lighting equipment is also simple. Although it is easy, it is comparable to many accessories. Once connected, various measurement tasks can be added.
2. Large tool microscope.
Its rotary table is assembled, and is also made of precision cross-shaped mobile table and observation microscope. The penetrating lighting equipment adopts centrifugal lighting. The pillar and table are integrally formed and can be tilted left and right. The thread measurement is very convenient. The eye observation unit is equipped with a projection device, which can be used for observation of projected images.
Determination of tool microscope
1. Cartesian coordinate measurement:
When measuring, the rectangular coordinate direction of the measured object must be consistent with the moving direction of the cross-shaped table. When using rectangular coordinate measurement, the rectangular coordinate value can be directly read by the movement of the cross moving table. If it is a large tool microscope, the correct measurement can be made by connecting the observation eye with the image on the rectangular coordinate measurement of the aiming hole, and the right angle of the measured object When correcting the coordinate direction and the cross-moving table, it is very convenient to use the assembled rotary table installed on the large tool microscope. As for the small tool microscope, only the rotary table attachment is required.
2. Angle measurement:
It can be determined by using a rotating table or an angle observation lens. Generally speaking, the accuracy of the angle observation lens is better.
3. Altitude measurement:
Although a small tool microscope cannot measure the height, if the measuring silver is installed on the upper end of the pillar, then the height can be measured by using the up and down movement of the microscope. However, it is very difficult to make a correct measurement due to the errors of the depth of focus, the inclination of the pillar, and the distance between the amount of silver and the optical axis.
4. Pore diameter measurement:
Generally, it is measured by using an angle observation lens, but a large-scale tool microscope can use an overlapping image observation lens or an optical detector, that is, using an overlapping image lens to overlap the two images generated, and then on the opposite side as well, so by The amount of movement shows the inner diameter of the hole. If an optical detector is used, first install it on the 3x object lens, then align the moving direction of the detector and the worktable, and then adjust the overlapping line in the observation mirror to be parallel to the cross line of the observation lens. Instead, the probe is brought into contact with the surface of the hole. *Finally, use the feed on the Y axis to correct the reverse movement of the overlapping line, and use the feed on the X axis to make the overlapping line clamp the cross line of the observation lens, and then the measured value on the X axis can be read. The same is true for the hole on the opposite side, so the difference between the readings and the diameter of the probe can be used to obtain the inner diameter of the hole.
