Embodiment Construction
[0009] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0010] A photoelectric encoder switch pressing mechanism, including a frame, is characterized in that: a spring base located on the upper part of the frame, the circumference of the spring base has at least one fixed connection hole, and the bottom of the spring base has a flange; There is a spring washer on the spring base, and the spring washer has a waist-shaped groove; a rotating shaft is penetrated in the spring base and the spring washer, and the rotating shaft is passed through the waist-shaped groove of the spring washer, so that the spring washer Follow the rotation of the rotating shaft, a convex ring is arranged on the rotating shaft, and a pressing spring is set on the rotating shaft between the convex ring and the spring washer, so that the rotating shaft has a pressing space; there is a stepped boss at the bottom of the rotating shaft , a grating base i...

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 [0001] The invention relates to a switch pressing mechanism, which is used in the design of integrated pressing switches of photoelectric encoders, and can be extended and applied to occasions where the function of pressing switches is added to a rotating shaft. technical background [0002] In the process of applying the photoelectric encoder, sometimes it is necessary to provide a set of pulses before receiving the code, which is used by the receiver as a sign of ready reception, which can be realized after integrating the photoelectric encoder with a push switch. In addition, this pulse signal can also be used as a sign of the end of receiving encoding, or for other purposes. However, the current photoelectric encoder has no sign of ready to receive or end of reception, that is, the current photoelectric encoder does not have a signal that can send a sign of ready to receive or end of reception, so the above functions can only be realized through additiona...
