Description
Technical field
The present invention relates to a kind of switch press mechanisms, integrate push switch design for photoelectric encoder, while expansible
It is applied to the occasion that rotary shaft increases push switch function.
Technical background
During application photoelectric encoder, it is sometimes desirable to before receiving coding, a set of pulses need to be provided, for receiving
Fang Zuowei prepares received mark, can realize after photoelectric encoder is integrated push switch.In addition, this pulse signal can also be made
For receive end-of-encode mark, or be used for other purposes.But current photoelectric encoder receives without preparation or terminates to connect
Mark is received, that is, current photoelectric encoder can not issue the signal for preparing to receive or terminate reception flag, therefore only
Have through additional electronic circuit and realize above-mentioned function, on the one hand increase production cost in this way, in addition operates others portion
Part is also given and is made troubles using photoelectric encoder.
Summary of the invention
It can be issued present invention aim to address photoelectric encoder in the prior art and reception flag is received or terminated without preparation
Device present in the above problem, photoelectric encoder switch press mechanism is provided.Push switch, function are integrated in optical encoder
Can on for recipient provide set of pulses signal, to realize purpose that optical encoder and microswitch function integrate, solve photoelectricity
The problem of encoder is without preparing reception or terminating reception flag.
In order to realize the purpose, the technical scheme is that：A kind of photoelectric encoder switch press mechanism, including machine
Frame, it is characterised in that：One is located at the spring pedestal of upper rack, and the border of the spring pedestal has an at least fixedly connected hole,
The bottom of the spring pedestal has a flange；There is a spring shim on spring pedestal, which has a kidney slot；?
A rotary shaft is installed in spring pedestal and spring shim, rotary shaft is arranged in the kidney slot of the spring shim, so that spring pad
Piece follows rotary shaft to rotate, and is provided with a flange collar on the rotary shaft, is set in the rotary shaft between flange collar and spring shim
One presses pressing spring, so that the rotary shaft has pressing activity space；There is a ladder boss in rotary shaft bottom, in frame lower
It is provided with a grating pedestal, which has a step groove, and the ladder boss cooperation of the step groove and rotary shaft makes
It obtains the rotary shaft push action to terminate at the step groove of the grating pedestal, be offered at the step groove bottom of grating pedestal logical
Hole, is provided with a microswitch below through-hole, and microswitch is mounted in a printed board.
Compared with existing optical encoder, the advantage of the invention is that：Microswitch is integrated in photoelectric encoder, thus
While coding being provided for recipient, it is additionally provided set of pulses signal, and mutually indepedent.
Detailed description of the invention
Fig. 1 is sectional view before mechanism of the invention presses, and Fig. 2 is the portion the A enlarged drawing of Fig. 1, and the portion B that Fig. 3 is Fig. 1 amplifies
Figure.
Fig. 4 is sectional view after mechanism pressing of the invention.
The portion the C enlarged drawing that Fig. 5 is Fig. 4, Fig. 6 are the portion the D enlarged drawing of Fig. 4.
Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.
A kind of photoelectric encoder switch press mechanism, including rack, it is characterised in that：One is located at the spring bottom of upper rack
Seat, the border of the spring pedestal have an at least fixedly connected hole, and the bottom of the spring pedestal has a flange；In spring pedestal
On have a spring shim, the spring shim have a kidney slot；It is installed with a rotary shaft in spring pedestal and spring shim, rotates
Axis is arranged in the kidney slot of the spring shim, so that spring shim follows rotary shaft to rotate, it is convex to be provided with one on the rotary shaft
It encloses, is set with one by pressing spring in the rotary shaft between flange collar and spring shim, so that the rotary shaft has pressing activity empty
Between；There is a ladder boss in rotary shaft bottom, frame lower is provided with a grating pedestal, which has a ladder
The ladder boss of groove, the step groove and rotary shaft cooperates, so that the rotary shaft push action terminates in being somebody's turn to do for the grating pedestal
At step groove, through-hole is offered at the step groove bottom of grating pedestal, a microswitch is provided with below through-hole, fine motion is opened
Pass is mounted in a printed board.
Referring to Figure 1 and Fig. 2, shown in figure is a kind of photoelectric encoder switch press mechanism, mainly by a rotary shaft
1, it one is formed by pressing spring 2, a spring shim 3, a spring pedestal 4, a grating pedestal 5, a printed board 6 and a microswitch 7,
Rack 8, thrust surface 9.
Referring to Figure 1, state before the described mechanism presses.By pressing spring 2 under precompression effect, by rotary shaft 1 and bullet
Spring gasket 3 is fixed on two sides, and spring shim 3 is tightly attached at the base flange of spring pedestal 4.Rotary shaft 1 is arranged in spring shim 3
Kidney slot in, there are certain distance between bottom ladder boss and the step groove of grating pedestal 5, which is to switch to press
The pressing stroke of press mechanism.Microswitch 6 is mounted in printed board 7, and printed board 7 and grating pedestal 5 fix it by screw rod
Relative position.
Refer to Fig. 2, state after the mechanism pressing.Rotary shaft 1 is squeezed under external force by pressing spring 2, rotation 1
The step surface of axis bottom ladder boss is in contact with the step groove of grating pedestal 5 and forms thrust surface, and the ladder of rotary shaft 1
Boss presses microswitch, carries out state output outward by printed board 7.When removing external force, rotary shaft 1 is pressing pressing spring 2
Active force under return back to Fig. 1 state, 6 reinstatement state of microswitch, then by the outside output state of printed board 7, thus defeated
A pulse signal out.
Embodiments of the present invention are only expressed above, and the description thereof is more specific and detailed, but can not therefore understand
