Technical Field

[0001] This utility model relates to the field of centering and adjustment technology, and in particular to a centering and adjustment reference detection clamping device. Background Technology

[0002] When using a centering instrument for reference testing of the microscope tube, the necessary measuring tools (such as measuring heads and dial indicators) are essential. Currently, companies mainly use magnetic bases to hold the measuring tools, adjust and fix their spatial position, and measure the dimensional data of the microscope tube.

[0003] The universal adjustment mechanism of the magnetic meter holder primarily employs hydraulic technology. Adjustment and fixation are achieved by tightening and loosening a knob. During fixation, the tightening force applied to the knob is critical; excessively loose tightening will lead to instability and wobbling, affecting measurement accuracy; excessively tight tightening may squeeze out the hydraulic oil, causing structural damage and failure. Operators often struggle to control the tightening force to reliably fix the magnetic meter holder, making measurement errors more likely. Utility Model Content

Figure 1 and Figure 17 First, using bolts through the longitudinal through holes of the rectangular base plate 1, the centering and adjustment reference detection clamping device of this utility model is installed and fixed on the optical platform and arranged on one side of the centering instrument lens mount E. Then, the measuring tool D is installed into the clamping member 9. According to the different external dimensions of the lens, the angle of the clamping member 9 relative to the crossbar 7 is adjusted, and the crossbar 7 on both sides of the strip notch 71 is driven by rotating the locking screw 10 to form a clamping force, clamping and fixing a pair of clamping pieces 91, thereby completing the installation and fixing of the measuring tool D. The spatial position of the measuring tool D is adjusted in three directions according to the requirements of the measurement point. Direction 1: Loosen the locking screw 3, move the slide block 2 along the slide rail 11 using the knob 25, and tighten the locking screw 3 after reaching the designated position.

The bottom end of the locking screw 38 is tightly attached to the crossbar 7 and fixed by friction, thereby realizing the spatial position adjustment of the clamping part 9 for measuring different positions.

[0030] Two centering and adjustment reference clamping devices as described in this utility model can also be used simultaneously for measurement, with reference to the given... Figure 18Two devices are respectively arranged on both sides of the centering instrument mount E. One device is raised using a pad to measure the upper end face of the lens barrel F under test, and the other device is used to measure the radial runout of the side surface of the lens barrel F under test. As the lens barrel F under test rotates, the horizontal reading of the lens reference plane and the pitch reading of the lens reference plane change simultaneously, thereby detecting the spatial position deviation of the lens and making further adjustments to the spatial position of the lens barrel.
