Calibration device for laser displacement sensor

Abstract

The invention provides a calibration device for a laser displacement sensor. Laser parameters can be conveniently calibrated; the device comprises a laser calibration plate and a dial indicator, the dial indicator is arranged on a fixed plate; the laser calibration plate and the fixed plate are connected through a mounting connecting block; a micrometer head mounting plate is mounted on the lasercalibration plate; a micrometer is assembled on the micrometer head mounting plate; a sleeve and a screw rod on the micrometer penetrate through the micrometer head mounting plate; the screw rod is connected with a balancing weight through a compression spring; a sliding assembly is arranged on the laser calibration plate; the sliding assembly comprises a sliding rail, a sliding plate is arrangedon the sliding rail through a sliding block; the sliding plate is connected with the screw rod through a follow-up block; a through groove is formed in the laser calibration plate below the sliding plate; the upper portion of an inverted-T-shaped side sliding block penetrates through the through groove and then is connected with the bottom face of the sliding plate, the length of the through groove is larger than that of the upper portion of the side sliding block and smaller than that of the lower portion of the side sliding block, optical glass is installed on the bottom face of the lower portion of the side sliding block, and a probe on the dial indicator penetrates through the fixed plate and then makes contact with the optical glass.

Description

technical field [0001] The invention relates to the technical field of laser calibration, in particular to a calibration device for a laser displacement sensor. Background technique [0002] Laser displacement sensors are often used to measure the structural stability of products (such as computer touch panels, etc.) under simulated working conditions, but the measurement accuracy requires high requirements, up to 0.001mm, so parameter setting and calibration of laser displacement sensors are required , in order to be able to obtain accurate data, but when calibrating the laser displacement sensor, generally only rely on experience to adjust the parameters of the laser displacement sensor, it is impossible to define whether the laser displacement sensor is adjusted to a relatively stable use state, and adjust It is also more difficult. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a calib...
