Description

Technical Field

[0001] The utility model relates to the technical field of laser interferometers, in particular to a laser interferometer base. Background Art

[0002] Laser has the advantages of high intensity, high directionality, spatial coherence, narrow bandwidth and high monochromaticity. Therefore, the laser interferometer is a universal length measuring device that uses the laser wavelength as a known length and uses the Michelson interferometer system to measure displacement. Since the use of the laser interferometer must be stable to maintain measurement accuracy, a special support base is required for easy installation and setup.

[0003] After searching, the Chinese patent authorization number CN202321794907.0 discloses a quick installation base for a laser interferometer, including a chassis and a connecting plate, the surface of the chassis is rotatably connected to a rotating shaft, a rotating mechanism fixedly connected to the rotating shaft is arranged inside the chassis, a receiving seat is fixedly connected to the top of the rotating shaft, a slot is provided on the surface of the receiving seat, a spherical slot is provided on the inner side wall of the slot, a bolt hole is provided on the surface of the connecting plate, an insert block is fixedly connected to the lower surface of the connecting plate, and the insert block fits in the slot, an embedding groove is provided on the side wall of the insert block, and a clamping mechanism is provided on the inner side wall of the embedding groove.

[0004] The quick-install base for a laser interferometer in the above patent has the following shortcomings: First, the above patent fixes the laser interferometer instrument by setting an elastic clamping mechanism. This fixing method is relatively unstable, the clamping ball is prone to falling off and wearing, and it is also inconvenient to replace, which reduces the overall service life of the base. Secondly, the fixing stability of the bottom end of the base is generally low, and it requires manual support or a special fixing mechanism for fixing. The unstable base is also likely to reduce the stability of the instrument, which in turn reduces the overall use effect.

[0005] To this end, we propose a laser interferometer base to solve the above problems. Utility Model Content

A slide groove 15 is provided at the top of the inner top of the receiving seat body 1. The slide groove 15 is mainly used to make the mobile extrusion rod 11 move stably and limit it. The sliding rod at the top extended end of the mobile extrusion rod 11 is connected to the inner side of the slide groove 15. The use of the above-mentioned components can not only make the turntable 5 drive the various components by toggling the circle block 3 to make the arc sleeve 12 and the elastic slide pad 16 fix the instrument panel 20 on multiple sides to increase the fixing stability, but also can be protected and wear-resistant by the elastic slide pad 16, reduce wear, and increase service life, and at the same time it does not affect the angle adjustment.
