Abstract

The invention relates to a lens device and an industrial endoscope. The lens device comprises a body, a lens piece, a coil assembly and a magnetic sliding piece. A containing cavity is formed in the body; the lens piece, the magnetic sliding piece and the coil assembly are all arranged in the containing cavity; the magnetic sliding piece is slidably connected to the cavity wall of the containing cavity in the axial direction of the body; the lens piece is arranged on the magnetic sliding piece and changes along with the change of the state of the magnetic sliding piece; the coil assembly is configured to generate magnetic field force for driving the magnetic sliding piece to move in the axial direction of the body, so that the magnetic sliding piece drives the lens piece to move in the axial direction of the body. The magnetic field force which enables the magnetic sliding piece to drive the lens piece to move in the containing cavity in the axial direction of the body is generated through the coil assembly, automatic position adjustment of the lens piece in the lens device is achieved, and therefore, automatic zooming of the lens device in a limited space is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial endoscopes, in particular to a lens device and an industrial endoscope. Background technique [0002] With the improvement of various manufacturing processes, many product processing and production enterprises currently use industrial endoscopes to check product quality or detection inspections. Industrial endoscopes can be used in places where high temperature, poisonous, nuclear radiation and human eyes cannot be directly observed. It is mainly used in the detection fields of automobiles, aero-engines, pipelines, mechanical parts, etc. It can realize non-destructive testing without disassembling or destroying the assembly and stopping the operation of the equipment. [0003] The camera imaging system of the traditional industrial endoscope is limited by the constraints and space structure, etc., all adopt fixed zoom technology or the zoom mode of manually changing the lens, so as to obtain cl...
