CN-224202459-U - Detachable long-distance adjustable cross laser positioner

Abstract

The utility model discloses a detachable long-distance adjustable cross laser positioner which comprises a front sleeve, a sliding sleeve, a rotating sleeve, a lens seat, a cylindrical lens assembly, an LD assembly and a tail fixing seat. The focal length is adjusted by matching the rotating sleeve with the threads of the lens seat, the double eccentric cylindrical lens group generates cross light spots, and the long-focal-length collimating lens controls the divergence angle of the light beam. The LD component adopts a quick-dismantling structure and supports the quick replacement of chips. The positioner has the characteristics of high beam precision (< 0.3 mRad), convenient adjustment (+/-5 mm adjusting range), low maintenance cost (the chip is replaced for 5 minutes), and the like, and is suitable for remote high-precision positioning scenes such as industrial measurement, building construction and the like.

Description

Detachable long-distance adjustable cross laser positioner Technical Field The utility model belongs to the field of laser positioners, and particularly relates to a detachable long-distance adjustable cross laser positioner. Background The existing laser locator has obvious technical bottlenecks in the fields of industrial measurement, building construction and the like. The traditional product generally adopts a wave lens structure, so that the generation precision of the cross light spot is insufficient, the divergence angle of the light beam is large (the typical value is more than 0.5 mRad), the line width of the light spot at the distance of 100 meters can reach 15-20mm, and the precision positioning requirement is difficult to meet. The optical system is designed with a fixed focal length, cannot be dynamically adjusted according to the working distance, and the adjusting mechanism needs to be operated by a special tool, so that the operation is complex. In addition, the core component laser chip (LD assembly) typically employs an epoxy encapsulation process, requiring an integral replacement of the positioner upon damage, resulting in long equipment downtime and up to 60% -80% of new price. More prominently, the existing products lack modularized design concept, the cylindrical lenses required by different operation scenes cannot be replaced quickly, and the environmental adaptability of the equipment is limited. These technical drawbacks have become a key factor limiting the application of laser positioners in remote high-precision scenes. Disclosure of utility model The utility model aims to provide a detachable long-distance adjustable cross laser positioner, which aims to solve the problems in the background technology. In order to achieve the purpose, the utility model adopts the following technical scheme: The utility model provides a detachable long-distance adjustable cross laser locator, including preceding cover, slip cap, swivel cap, lens seat, post mirror subassembly, LD subassembly and afterbody fixing base, the internally mounted of swivel cap has the slip cap, and the internally mounted of slip cap has the lens seat, and the post mirror subassembly is installed to the front end of lens seat, and the front end of post mirror subassembly is installed and is overlapped before the front end of slip cap and cover threaded connection, and the LD subassembly is installed to the rear end of swivel cap, and the afterbody fixing base passes through the screw fixation at the rear end of swivel cap, the rear end of slip cap and LD subassembly threaded connection. Preferably, the column mirror assembly comprises a column mirror seat, a fixing hole and four column mirrors, wherein a plurality of mounting holes are formed in the column mirror seat and used for detachably mounting the four column mirrors. Preferably, the LD assembly comprises an LD sleeve and an LD seat, the rear end of the sliding sleeve is in threaded connection with the LD sleeve, and the LD sleeve is arranged between the tail fixing seat and the LD seat. Preferably, the sliding sleeve comprises a sliding sleeve body and a sliding hole, wherein the sliding hole is formed in the sliding sleeve body and used for sliding the lens seat in the sliding sleeve body. Preferably, the surface of the lens seat is provided with a plurality of protruding blocks, the surface of each protruding block is provided with threads, and the threads are matched with the threads of the rotary sleeve. Preferably, the four-cylinder lens is a double eccentric cylinder lens The utility model has the beneficial effects that: The optical performance is improved by adopting a double eccentric cylindrical lens group (four-cylindrical lens structure) to realize the generation of precise cross light spots, configuring a long-focus collimating lens and controlling the beam divergence angle to be less than 0.3mRad and the line width of 100 meters distance to be less than or equal to 10mm; The detachable design is that the LD component and the tail fixing seat adopt a thread quick-release structure, the chip replacement time is shortened to 5 minutes from the traditional 2 hours, the cylindrical lens component realizes modularized installation through the fixing hole, and the quick replacement of lenses with different focal lengths is supported; The adjusting convenience is that the rotary sleeve is in threaded fit with the lens seat through the convex blocks, the focal length adjusting range of +/-5 mm is achieved, the sliding hole of the sliding sleeve is designed to support the axial fine adjustment of the lens seat, and the adjusting precision is 0.1mm.
