Description
Technical field
The utility model relates to a kind of switch press mechanism, and for the integrated pressing switch designs of photoelectric encoder, easily extensible is applied to the occasion that turning axle increases pressing switching function simultaneously.
Technical background
In application photoelectric encoder process, sometimes needed before received code, need a set of pulses be provided, for take over party as the mark preparing to receive, just can realize integrated for photoelectric encoder after compressing switch.In addition, this pulse signal also can be used as the mark that received code terminates, or for other purposes.But current photoelectric encoder receives without preparation or terminates receiving flag, namely current photoelectric encoder does not have to send the signal preparing to receive or terminate receiving flag, therefore only have and realize above-mentioned functions by extra electronic circuit, such one side increases production cost, operates other parts in addition also to using photoelectric encoder to make troubles.
Summary of the invention
The purpose of this utility model solves photoelectric encoder in prior art can send without preparation reception or the problems referred to above existing for device terminating receiving flag, provides photoelectric encoder switch press mechanism.Integrated by compressing switch in optical encoder, functionally for take over party provides set of pulses signal, to realize the object of optical encoder and microswitch function i ntegration, solve photoelectric encoder without the problem preparing to receive or terminate receiving flag.
In order to realize this purpose, the technical solution of the utility model is: a kind of photoelectric encoder switch press mechanism, comprises frame, it is characterized in that: a spring pedestal being positioned at upper rack, the border of this spring pedestal has and is at least onely fixedly connected with hole, and the bottom of this spring pedestal has a flange; Spring pedestal has a spring shim, and this spring shim has a kidney slot; A turning axle is installed with in spring pedestal and spring shim, turning axle is arranged in this kidney slot of this spring shim, make spring shim follow turning axle to rotate, be provided with a flange collar on the rotary shaft, turning axle between flange collar and spring shim is set with one by pressing spring, makes this turning axle have pressing activity space; There is a ladder boss bottom turning axle, frame lower is provided with a grating base, this grating base has a step groove, this step groove coordinates with the ladder boss of turning axle, this turning axle push action is made to terminate in this step groove place of this grating base, at the bottom of the step groove of grating base, offer through hole, be provided with a microswitch below through hole, microswitch is arranged in a printed board.
Compared with existing optical encoder, the utility model has the advantage of: microswitch is integrated in photoelectric encoder, thus can be while take over party provides coding, set of pulses signal is additionally provided, and separate.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
A kind of photoelectric encoder switch press mechanism, comprises frame, it is characterized in that: a spring pedestal being positioned at upper rack, and the border of this spring pedestal has and is at least onely fixedly connected with hole, and the bottom of this spring pedestal has a flange; Spring pedestal has a spring shim, and this spring shim has a kidney slot; A turning axle is installed with in spring pedestal and spring shim, turning axle is arranged in this kidney slot of this spring shim, make spring shim follow turning axle to rotate, be provided with a flange collar on the rotary shaft, turning axle between flange collar and spring shim is set with one by pressing spring, makes this turning axle have pressing activity space; There is a ladder boss bottom turning axle, frame lower is provided with a grating base, this grating base has a step groove, this step groove coordinates with the ladder boss of turning axle, this turning axle push action is made to terminate in this step groove place of this grating base, at the bottom of the step groove of grating base, offer through hole, be provided with a microswitch below through hole, microswitch is arranged in a printed board.
Refer to Fig. 1 and Fig. 2, shown in figure is a kind of photoelectric encoder switch press mechanism, form by pressing spring 2, spring shim 3, spring pedestal 4, grating base 5, printed board 6 and a microswitch 7 primarily of a turning axle 1, frame 8, thrust surface 9.
Refer to Fig. 1, state before this mechanism described pressing.By pressing spring 2 under precompression effect, turning axle 1 and spring shim 3 are fixed on both sides, and the base flange place of spring pedestal 4 is close to by spring shim 3.Turning axle 1 is arranged in the kidney slot of spring shim 3, leaves certain distance between bottom ladder boss and the step groove of grating base 5, and this distance is the pressing stroke of switch press mechanism.Microswitch 6 is mounted in printed board 7, and printed board 7 and grating base 5 fix its relative position by screw rod.
Refer to Fig. 2, state after this mechanism described pressing.Turning axle 1 extrudes under external force and presses pressing spring 2, the step surface rotating ladder boss bottom 1 axle contacts with the step groove of grating base 5 and forms thrust surface, and the ladder boss pressing microswitch of turning axle 1, outwards carry out State-output by printed board 7.When removing external force, turning axle 1 returns back to Fig. 1 state under the acting force by pressing spring 2, and microswitch 6 restores to the original state state, then by printed board 7 outwards output state, thus export a pulse signal.
Below only have expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Advantage of the present utility model: microswitch is integrated in photoelectric encoder, thus can be while take over party provides coding, set of pulses signal is additionally provided, and separate.
