Abstract
A position-limit mechanism based on fluted body optoelectronic switch, belongs to technical field of medical instruments.Its structure is by optoelectronic switch (1), fixed mount (2), gathering sill (3), back-moving spring (4), cushion pad rubber (5) and shading catch frame (6) form, it is characterized in that: optoelectronic switch (1), cushion pad rubber (5) is fixed on fixed mount (2), gathering sill (3) is to be fastened and formed by buckle by two parts, buckle by lower end is arranged on fixed mount (2) again, back-moving spring (4) one end is enclosed within on the boss on fixed mount (2), the other end is enclosed within on the boss of shading catch frame (6), back-moving spring (4) under initial condition in compressive state, shading catch frame (6) forms straight-line motion mechanism by two back-moving springs (4) and gathering sill (3).Its advantage is: simple in structure, easy for installation, spacing contact is many, fast response time, and buffer distance is long, and anti-electromagnetic interference capability is strong.
Description
Technical field
The utility model belongs to technical field of medical instruments.
Background technology
Along with developing rapidly of China's industrial automation technology, optoelectronic switch Automation Elements will generally be adopted, application is also in continuous expansion, because of it, to have volume little, life-span is long, precision is high, fast response time and anti-electromagnetic interference capability the various features such as by force, being used as at present thing position detects, liquid level is controlled, product counting, width is differentiated, speed detects, cut-to-length, hole identification, the numerous areas such as punch press and cutter and security protection, and conventional limit switch carries out spacing control to its moving component in various motions and position control apparatus, as be widely used in all kinds of lathes and hoisting machinery, in order to control its stroke, carry out the limit switch of terminal position limitation protection, but this limit switch generally exists response speed low, low precision, contact detection is easily damaged detected material and the shortcoming such as the life-span is short.
Fluted body optoelectronic switch is a kind of contactless optical electric switch, its groove width is only 5mm, object to be detected must be narrower than its groove width so, so linear-motion object in being used among a small circle general main detects as cut-to-length, or pinpoint circular motion detects as tachometric survey, and use has some limitations, Given this, how fluted body optoelectronic switch is applied in position-limit mechanism, better improving spacing reliability will be the focal issue that designers think deeply.
Summary of the invention
The purpose of this utility model is: the limitation of using for weak point and the fluted body optoelectronic switch of contact limit switch in the past, provides a kind of position-limit mechanism based on fluted body optoelectronic switch.
The utility model solves the technical scheme that its technical problem adopts: its structure is by optoelectronic switch, fixed mount, gathering sill, back-moving spring, cushion pad rubber and shading catch frame form, it is characterized in that: optoelectronic switch, cushion pad rubber is fixed on fixed mount, gathering sill is to be fastened and formed by buckle by two parts, buckle by lower end is arranged on fixed mount again, back-moving spring one end is enclosed within on the boss on fixed mount, the other end is enclosed within on the boss of shading catch frame, back-moving spring under initial condition in compressive state, shading catch frame forms straight-line motion mechanism by two back-moving springs and gathering sill.
The beneficial effects of the utility model are: fast response time, buffer distance are long, and anti-electromagnetic interference capability is strong, and not fragile optoelectronic switch; Spacing contact is many and wide, and applicability is strong, and the object of motion is had to good buffering effect; Simple in structure, easy for installation, low cost of manufacture.

Fig. 3: a kind of spacing figure in position of the position-limit mechanism based on fluted body optoelectronic switch.
In Fig. 1: 1, optoelectronic switch, 2, fixed mount, 3, gathering sill, 4, back-moving spring, 5, cushion pad rubber, 6, shading catch frame.
Embodiment
Contrast accompanying drawing, its structure is by optoelectronic switch (1), fixed mount (2), gathering sill (3), back-moving spring (4), cushion pad rubber (5) and shading catch frame (6) form, it is characterized in that: optoelectronic switch (1), cushion pad rubber (5) is fixed on fixed mount (2), gathering sill (3) is to be fastened and formed by buckle by two parts, buckle by lower end is arranged on fixed mount (2) again, back-moving spring (4) one end is enclosed within on the boss on fixed mount (2), the other end is enclosed within on the boss of shading catch frame (6), back-moving spring (4) under initial condition in compressive state, shading catch frame (6) forms straight-line motion mechanism by two back-moving springs (4) and gathering sill (3).
Its implementation is: in the groove gap of moving object acts on arbitrary place → two back-moving spring (4) of shading catch frame (6) contact region compressed → shading catch frame (6) is inserted into completely along gathering sill (3) travel forward → shading catch frame (6) optoelectronic switch (1) → and optoelectronic switch (1) feeds back signal to control unit (omitting) → treat moving object active force cancellation → shading catch frame (5) motion backward under back-moving spring (4) active force herein, returns to initial condition.Size determines according to optoelectronic switch, fixed mount, gathering sill, back-moving spring, shading catch frame, and the design tentatively selects optoelectronic switch EE-SX670.
Its advantage is: simple in structure, easy for installation, spacing contact is many, fast response time, and buffer distance is long, and anti-electromagnetic interference capability is strong.
