Abstract
The invention relates to a photoelectric encoder switch pressing mechanism comprising a frame. The mechanism is characterized in that a spring base is arranged on the upper part of the frame, and the bottom of the spring base is provided with a flange; a spring washer is arranged on the spring base; a rotating shaft penetrates through the spring base and the spring washer, which makes the spring washer rotate with the rotating shaft; the rotating shaft is provided with a convex ring; the rotating shaft between the convex ring and the spring washer is sleeved with a pressing spring; the bottom of the rotating shaft is provided with a stepped boss; a grating base is arranged on the lower part of the frame; the grating base is provided with a stepped groove, and the stepped groove and the stepped boss of the rotating shaft match each other so as to make the pressing action of the rotating shaft stop at the stepped groove of the grating base; and the bottom of the stepped groove of the grating base is provided with a through hole, a micro switch is arranged under the through hole, and the micro switch is mounted on a printed board. The photoelectric encoder switch pressing mechanism has the advantage that the micro switch is integrated in a photoelectric encoder so as to provide coding for a receiver and to additionally provide a set of pulse signals, with the two motions being independent.
Description
Technical field
The present invention relates to a kind of switch press mechanism, for the integrated pressing switch designs of photoelectric encoder, expansible application simultaneously increases the occasion of pressing switching function to rotating shaft。
Technical background
In application photoelectric encoder process, it is sometimes desirable to before receiving coding, a set of pulses need to be provided, for recipient as the mark preparing reception, just can realize integrated for photoelectric encoder by after compressing switch。It addition, this pulse signal is alternatively arranged as the mark receiving end-of-encode, or for other purposes。But current photoelectric encoder is without preparing to receive or terminate to receive mark, namely current photoelectric encoder does not have to send the signal preparing to receive or terminate to receive mark, therefore only above-mentioned functions is realized by extra electronic circuit, increase production cost so on the one hand, additionally operate other parts also to using photoelectric encoder to make troubles。
Summary of the invention
Present invention aim to address that photoelectric encoder in prior art can send without the problems referred to above existing for device preparing to receive or terminate to receive mark, it is provided that photoelectric encoder switch press mechanism。In optical encoder integrated by compressing switch, functionally provide set of pulses signal for recipient, the purpose integrated to realize optical encoder and microswitch function, solve photoelectric encoder without the problem preparing to receive or terminate to receive mark。
In order to realize this purpose, the technical scheme is that a kind of photoelectric encoder switch press mechanism, including frame, it is characterised in that: one is positioned at the spring pedestal of upper rack, the border of this spring pedestal has at least one fixing connecting hole, and the bottom of this spring pedestal has a flange；Having a spring shim on spring pedestal, this spring shim has a kidney slot；Spring pedestal and spring shim are installed with a rotating shaft, rotating shaft is arranged in this kidney slot of this spring shim, make spring shim follow rotating shaft to rotate, it is provided with a flange collar on the rotary shaft, rotating shaft between flange collar and spring shim is set with one by pressing spring so that this rotating shaft has pressing activity space；There is a ladder boss bottom rotating shaft, frame lower is provided with a grating base, this grating base has a step groove, this step groove coordinates with the ladder boss of rotating shaft, this rotating shaft push action is made to terminate in this step groove place of this grating base, offering through hole at the bottom of the step groove of grating base, be arranged below a microswitch at through hole, microswitch is arranged in a printed board。
Compared with existing optical encoder, it is an advantage of the current invention that: microswitch is integrated in photoelectric encoder, thus while coding can being provided for recipient, set of pulses signal being additionally provided, and separate。

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated。
A kind of photoelectric encoder switch press mechanism, including frame, it is characterised in that: one is positioned at the spring pedestal of upper rack, and the border of this spring pedestal has at least one fixing connecting hole, and the bottom of this spring pedestal has a flange；Having a spring shim on spring pedestal, this spring shim has a kidney slot；Spring pedestal and spring shim are installed with a rotating shaft, rotating shaft is arranged in this kidney slot of this spring shim, make spring shim follow rotating shaft to rotate, it is provided with a flange collar on the rotary shaft, rotating shaft between flange collar and spring shim is set with one by pressing spring so that this rotating shaft has pressing activity space；There is a ladder boss bottom rotating shaft, frame lower is provided with a grating base, this grating base has a step groove, this step groove coordinates with the ladder boss of rotating shaft, this rotating shaft push action is made to terminate in this step groove place of this grating base, offering through hole at the bottom of the step groove of grating base, be arranged below a microswitch at 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, mainly it is made up of by pressing spring 2, spring shim 3, spring pedestal 4, grating base 5, printed board 6 and a microswitch 7 rotating shaft 1, frame 8, thrust surface 9。
Refer to Fig. 1, state before this mechanism described pressing。By pressing spring 2 under precompression effect, rotating shaft 1 and spring shim 3 being fixed on both sides, the base flange place of spring pedestal 4 is close to by spring shim 3。Rotating shaft 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。Rotating shaft 1 extrudes under external force and presses pressing spring 2, rotates the step surface of ladder boss bottom 1 axle and contacts with the step groove of grating base 5 and form thrust surface, and the ladder boss of rotating shaft 1 pressing microswitch, State-output is outwards carried out by printed board 7。When removing external force, rotating shaft 1 returns back to Fig. 1 state under the active force by pressing spring 2, and microswitch 6 restores to the original state state, again through the outside output state of printed board 7, thus exporting 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, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention。Therefore, the protection domain of patent of the present invention should be as the criterion with claims。
Advantages of the present invention: microswitch is integrated in photoelectric encoder, thus while coding can being provided for recipient, set of pulses signal being additionally provided, and separate。
