Technical field
The invention belongs to optical path adjusting technical field in optical system, and in particular to one kind rotation direct drive electric diaphragm.
Background technology
Diaphragm can control the break-make of light path, and opening for diaphragm in the light path debugging of optical system and the course of work Closing can be using control and Electronic control two ways manually.Due to manually control can not accurately grasp diaphragm opening/closing time and Speed, and in some special application scenarios (such as high power laser light path), more dangerous, positioning precision is controlled manually It is not high, therefore need to use Electronic control diaphragm mostly.
Chinese utility model patent CN203164511U disclosed in August in 2013 28 days proposes a kind of motorized adjustment light Then door screen, the diaphragm is again transported the convert rotational motion of leading screw for the straight line of absorption cell support using motor driving leading screw rotation It is dynamic.Chinese utility model patent CN206074847U disclosed in 5 days April in 2017 proposes another motorized adjustment diaphragm, should Diaphragm uses motor driving flange disc spins, is then again transferred to the rotary motion of ring flange by a connecting rod adjustable Diaphragm pulls handle.
Although both the above motorized adjustment diaphragm can realize the open and close controlling of diaphragm, middle machine is also all relied on The power transmission of structure, the presence of transmission mechanism not only increases the production and processing cost of diaphragm, more crucially easily in frequency Broken down in numerous diaphragm opening and closing regulation, serious can also cause the destruction of imaging system.
The content of the invention
Direct drive electric diaphragm is rotated it is an object of the present invention to provide one kind, intermediate transmission link is eliminated, solves existing Motorized adjustment diaphragm production cost is high, regulation stability difference technical problem.
The present invention technical solution be:One kind rotation direct drive electric diaphragm, including motor and the light with inner chamber Light hole is provided with late main body, diaphragm main body, it is characterized in that:The inner chamber of the diaphragm main body is provided with controllable register It is provided with the sliding block in eccentric position, controllable register and is provided with and the sliding block on the rotor being connected with motor, rotor The sliding groove being adapted.
Further, the inner chamber of above-mentioned diaphragm main body is rectangular configuration, and the controllable register includes the first baffle of rectangle With the second baffle of rectangle, aperture is provided with second baffle;The sliding block includes the first sliding block and the second sliding block, wherein the One sliding block is located in the sliding groove of first baffle, and the second sliding block is located in the sliding groove of second baffle.
Further, the inner chamber of above-mentioned diaphragm main body is sector shape structure, and two opposite flanks of the controllable register are With the arcuate flanks of sector shape structure inner chamber sliding contact.
Further, above-mentioned controllable register is sandwich sandwich, and intermediate layer is stereotype, and two layers is steel plate in addition;Three Deck panels are riveted using aluminum rivet and fixed.
Further, above-mentioned sliding block is the sliding block of cylindrical protrusions structure, and the sliding groove is the slip of kidney-shaped pore structure Groove.
Further, illumination hole is additionally provided with above-mentioned diaphragm main body, illumination installs lighting source in hole.
The beneficial effects of the present invention are:
(1) present invention uses motor driven rotor, and the eccentric shoe on rotor is arranged on to the sliding groove of controllable register Interior, while rotor is rotated, sliding block is slided in sliding groove, so that drive controllable register to be moved in the inner chamber of diaphragm main body, Complete the open and close controlling of light hole.The opening and closing process of diaphragm is directly driven by a motor, and is eliminated the drive mechanism of complexity, is reduced The production and processing cost of electronic diaphragm simultaneously improves diaphragm regulation stability.
(2) inner chamber of diaphragm main body could be arranged to sector shape structure in the present invention, corresponding to be set to controllable register There is the arc sliding side of same radius with sector structure, matched with the rotary motion of rotor, when reducing rotor rotation Driving resistance, it is to avoid the appearance of Caton phenomenon.
(3) controllable register is set to sandwich sandwich by the present invention, can effectively prevent electromagnetism and various ray spokes It is shot through overregulating baffle plate and producing influence to subsequent optical part.
(4) present invention can provide stable photograph by setting illumination hole and lighting source in diaphragm main body for light field Bright condition.
