In order to achieve the above object, the present invention provides a technical solution: a multi-cam type electric pushing device comprises a frame, a power source, cams, a transmission shaft, a push rod assembly, a push plate, a guide rod and a sensor, wherein the plurality of cams are arranged on the frame along the same axial direction through two bearing supporting seats at two ends of each cam respectively to form a row, every two adjacent cams are connected through the transmission shaft, the plurality of cams are driven by the power source to synchronously rotate, each cam is matched with one push rod assembly, the push rod assembly comprises a connecting rod and a push rod, the connecting rod is arranged on the cam at a position deviating from the axis of the cam through a bearing, one end of the push rod is hinged with the connecting rod, the other end of the push rod penetrates through a first linear bearing fixed on the frame and is connected with the push plate, the push rod assembly drives the push plate to do reciprocating motion of pushing and resetting through the rotation of the cam, and the guide rod and the sensor which are, the guide rod is parallel to the push rod, one end of the guide rod is connected with the push plate, the other end of the guide rod penetrates through a second linear bearing fixed on the rack, the sensor is installed on the rack and obtains a signal when the end of the guide rod leaves or approaches the sensor, so that the start or stop of a power source is controlled, and finally the automatic control of the push plate to be pushed out and reset is realized.
Further, the power source is provided with one and is arranged on the frame, and the power source is connected with the cam close to the end part of the frame through a transmission shaft.
Furthermore, the connecting shafts at the two ends of the cam are connected with the transmission shaft through transmission pins.
Further, the sensor is a proximity sensor.
Further, the power source is a motor.
Compared with the prior art, the utility model, have following advantage and beneficial effect:
1. the utility model adopts the motor to drive the cam, the starting speed is stable, and the whole degree is controllable; the device is particularly suitable for occasions with high time matching requirements, automatic production occasions with accurate push-out or occasions with high-speed push-out.
2. The utility model discloses a stationarity and the smooth and easy nature of push pedal when many cams promote + many guide bars guarantee to release are particularly useful for the high-speed release, or the longer condition of push pedal size.
3. The utility model discloses the torsion transmission between each cam adopts transmission shaft + transmission pin junction, has reduced the requirement of assembly precision, when having avoided each cam to rotate simultaneously, causes the card to pause because of the distortion of transmission shaft overlength.
4. The utility model discloses a can receive release counterforce during cam gyration swing connecting rod, but two bearing support seats of every cam through its both ends are fixed, the effectual stability of guaranteeing the structure atress, and the transmission shaft between each cam is not a body structure simultaneously, therefore the reverse thrust of each cam can not exert an influence to other cams.
5. The utility model discloses a proximity sensor and guide bar non-contact control release/action that resets, structural design is ingenious, performance safe and reliable.
