[0009] The utility model is now described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0010] A diversified engine tray limiter auxiliary switch device, including an in-place sensor 1, a counting relay 4, a knob switch 5, a time relay 6, a solenoid valve 7 and an execution cylinder 8; the in-place sensor 1, the knob switch 5, the time relay 6, and the solenoid valve 7 are respectively connected to the counting relay 4 through a circuit, and the auxiliary switch device circuit can be controlled to operate or stop by turning on or off the knob switch 5. The in-place sensor 1 is arranged on the production station, and the in-place sensor 1 is used to sense the position of the engine tray 11. The execution cylinder 8 is arranged next to the engine tray limiter 10 of the engine rotating tooling, and the execution cylinder 8 is extended when the working end of the telescopic working end is extended. The start / stop switch of the engine tray limiter 10 can be pressed or toggled to enable the actuator cylinder 8 to start and stop the engine tray limiter 10. The solenoid valve 7 is arranged on the air supply path of the actuator cylinder 8. The solenoid valve 7 is controlled by the time relay 6 and the counting relay 4 to realize the control of the on / off of the air supply path of the actuator cylinder 8. When the in-position sensor 1 detects that the engine tray 11 on the engine rotating tooling moves to the work position, it sends a signal to the counting relay 4. The counting relay 4 controls the time relay 6 to work, and the time relay 6 controls the solenoid valve 7 to work. The control of the engine tray limiter 10 is further completed by controlling the actuator cylinder 8 to work.

[0011] The diversified engine tray limiter auxiliary switch device also includes an angle sensor 2 and an abnormal release sensor 3; the angle sensor 2 and the abnormal release sensor 3 are both arranged on the production station, the angle sensor 2 is used to sense the rotation of the engine tray 11, and the abnormal release sensor 3 is used to sense the abnormal position of the engine tray 11.

[0012] The diversified engine tray limiter auxiliary switch device also includes an actuator cylinder bracket 9, which is fixedly arranged on the production line, and the actuator cylinder 8 is fixedly arranged on the actuator cylinder bracket 9. The actuator cylinder bracket 9 is preferably arranged at an angle of 45 degrees.

[0013] The in-place sensor 1 and the abnormal release sensor 3 both adopt photoelectric sensors. The in-place sensor 1 is used to sense whether the engine tray 11 has reached the specified position of the production station. When the engine tray 11 reaches the specified position, the in-place sensor 1 will feed back the signal to the signal processing system and transmit it to the counting relay 4, thereby controlling the operation of the entire device; the abnormal release sensor 3 is used to sense whether there is an engine on the engine tray 11. If there is an engine, the signal is fed back to the signal processing system and sent to the counting relay 4. If there is no engine on the engine tray 11, it is an abnormal state, and no signal feedback is performed, that is, the engine tray 11 is released.

[0014] The working principle of the diversified engine tray limiter auxiliary switch device:

[0015] After completing the layout of each component, follow the following process to use it.

[0016] S1: After the arrival sensor 1 senses that the engine tray 11 has arrived at the workstation, it sends a signal to the counting relay 4;

[0017] S2: The counting relay 4 controls the time relay 6 to work. When the set time is reached, the time relay 6 controls the solenoid valve 7 to work.

[0018] S3: The solenoid valve 7 controls the execution cylinder 8 through compressed air, and the execution cylinder 8 extends to open the engine tray limiter 10;

[0019] S4: After the engine tray stopper 10 is opened, the engine tray 11 starts to rotate. When the angle sensor 2 senses a signal, it sends the signal to the counting relay 4. The counting relay 4 controls the solenoid valve 7 to drive the execution cylinder 8 to retract, so that the engine tray stopper 10 is closed, and then enters the next cycle action;

[0020] S5: The abnormal release sensor 3 and the knob switch 5 do not need to be set up with an opening and closing limiter, thereby realizing manual release and abnormal handling operations.

[0021] The overall structural layout of the device can be adjusted according to the different production stations on the engine production line to adapt to the work requirements of different stations on the engine production line.
