Description
Technical field
The utility model relates to a kind of accessory field of industrial camera, particularly relates to a kind of focusing mechanism of optical system of industrial camera.
Background technology
Industrial lens, as the vitals of machine vision, is mainly used in collected light and is become on the CCD/CMOS sensor surface of camera or video camera by the optical image of the target that is taken, allowing camera or video camera can collect clear sharp keen image.Along with the develop rapidly of industrial lens, current industrial lens is widely used on industrial detection, intelligent transportation, scanning and copying device and photographic camera, and this just needs camera lens can adapt to the needs of different object distances, requires that camera lens has focusing and zoom function.And current industrial lens all only has zoom function, owing to not having focus function, when object distance is nearer, scenic imagery will be smudgy, and how realizing industrial lens can compatiblely focus and zoom function, is applicant's problem demanding prompt solution.
Summary of the invention
In order to solve the deficiency that prior art exists, the utility model provide a kind of simple structure flexibly, convenient, the transmission of low cost, mounting or dismounting focuses stable focusing mechanism of optical system.
To achieve these goals, the technical solution adopted in the utility model is: a kind of focusing mechanism of optical system, comprise straight cylinder, rotary cylinder, driving member, for installing the focusing part of eyeglass and the fixed interface for being connected camera; The outer wall of described straight cylinder is provided with a circle boss; On described straight cylinder around central axis be uniformly distributed and with the straight groove of centerline axis parallel; Described rotary cylinder is provided with around the equally distributed tipper of central axis; Described driving member is cylindric and inside is provided with T font through hole; Described driving member is arranged in tipper; Described focusing part is provided with fixed orifice; Described straight groove, tipper and fixed orifice cooperatively interact straight cylinder, transmission cylinder to be screwed with focusing part and are connected; Described fixed interface and straight cylinder are fixedly linked; Between the boss that described rotary cylinder is socketed in straight cylinder and fixed interface.
Further improvement, the length of described straight groove is 0.1mm ~ 100mm.
Further improvement, the axial distance of described tipper is 0.1mm ~ 100mm.
After adopting the technical solution of the utility model, the camera lens in focusing part can install simple group optical focusing eyeglass, two groups of optical focusing eyeglasses or multigroup optical focusing eyeglass as required, and the image planes end of fixed interface is connected with camera.When left rotation and right rotation rotary cylinder, because rotary cylinder is arranged between boss and fixed interface, boss limits it and moves up, and fixed interface limits it and moves down.Such rotary cylinder when rotated, moves up and down realization steadily focusing by driving member mobile focusing part that drives in the rotation slot of rotary cylinder and the straight groove of straight cylinder, ensures that object can by camera lens clear focal imaging on camera.The utility model simple structure is flexible, mounting or dismounting are convenient, ensure that transmission focusing is steady simultaneously.

Embodiment
Illustrate below in conjunction with accompanying drawing and the preferred scheme of the utility model is further described.
As shown in Figure 1 to Figure 3, a kind of focusing mechanism of optical system, comprise straight cylinder 1, rotary cylinder 2, driving member 3, for installing the focusing part 4 of eyeglass and the fixed interface 5 for being connected camera.
The outer wall of described straight cylinder 1 is provided with a circle boss 11; On described straight cylinder 1 around three central axis be uniformly distributed and with the straight groove 12 of centerline axis parallel; Angle between three straight grooves is 120 degree, and the length of described straight groove 12 can be designed as 0.1mm ~ 100mm according to the dimensional requirement of optical focusing part.Described rotary cylinder 2 is provided with three around the equally distributed tipper 21 of central axis; The axial distance of described tipper 21 is 0.1mm ~ 100mm.Described driving member 3 be three identical in cylindric and inside is provided with T font through hole; Described driving member 3 is arranged in tipper 21.Described focusing part 4 is provided with three in 120 degree of equally distributed fixed orifices 41.Described straight groove 12, tipper 21 and fixed orifice 41 cooperatively interact by straight cylinder 1, transmission cylinder 2 and focusing part 4 be fixedly linked by screw 6; Described fixed interface 5 is fixedly linked with straight cylinder 1; Between the boss 11 that described rotary cylinder 2 is socketed in straight cylinder 1 and fixed interface 5.
Assembling process:
First focusing part 4 is inserted straight cylinder 1, again rotary cylinder 2 is socketed on the outer wall of straight cylinder 1, then three driving members are encased in the tipper of rotary cylinder 2, adjust the relative position of straight cylinder 1, focusing part 4 and rotary cylinder 2, tipper, straight groove and fixed orifice are adjusted to sight alignment, are each passed through tumbler 3 with three screws 6 and straight cylinder 1, focusing part 4 and rotary cylinder 2 are fixedly linked; Finally by three screws, straight cylinder 1 is fixedly linked with fixed interface 5.After completing, fixed interface 5 is fixedly connected with the mode of camera by threaded engagement.
