Detailed Description
The following detailed description of embodiments of the invention is intended to be illustrative, and not to be construed as limiting the invention.
The electromagnet buffering mechanism for the airborne photoelectric detection equipment in the embodiment comprises a telescopic rod 1, a permanent magnet 2, a pressing ring 3, an electromagnet 4, a base 5, a screw 6 and a check ring 7.
The telescopic rod 1 is of a segmented structure and sequentially comprises the following components from front to back: the contact plate, the magnet mounting section, the boss section and the motion guide rod section are used for contacting with a motion part in the airborne photoelectric detection equipment;
the permanent magnet 2 is sleeved on the magnet installation section of the telescopic rod 1, a round hole in the center of the permanent magnet 2 is matched with the cylindrical surface of the magnet installation section of the telescopic rod 1 by adopting a small gap, and the round hole is fixed on the telescopic rod 1 through a pressing ring 3; the pressing ring 3 is in threaded connection with the telescopic rod 1, the pressing ring 3 is screwed down by a straight groove which is used for clamping the end face of the pressing ring 3 by a # -shaped spanner, and thread glue is coated for preventing looseness.
The permanent magnet 2 is made of neodymium iron boron magnet, and is strong in magnetism and stable.
The base 5 is provided with a central axial through hole and an annular electromagnet mounting groove positioned outside the central axial through hole. The electromagnet 4 is arranged in an electromagnet mounting groove in the base 5; the rear end face of the base 5 is provided with a plurality of counter bores, and the bolts 6 penetrate through the counter bores to fix the electromagnet 4 in the electromagnet mounting groove. The rear end face of the base 5 is also provided with a lead perforation of the electromagnet 4, and a cable of the electromagnet 4 extends out of the lead perforation on the back face of the base 5 and is connected to a power supply device.
The iron core of the electromagnet 4 is made of soft iron, and when the electromagnet is not electrified, the soft iron does not have the capability of keeping magnetism, so that the strength of the magnetism of the electromagnet can be changed by controlling the magnitude of current.
The motion guide rod section of the telescopic rod 1 is inserted into the central axial through hole of the base 5, and the cylindrical surface of the motion guide rod section is in clearance fit with the central axial through hole of the base 5, so that the motion guide rod section can axially move along the central axial through hole of the base 5. A retainer ring 7 is further fixed at the end part of the motion guide rod section of the telescopic rod 1 and used for preventing the telescopic rod 1 from being separated from the central axial through hole of the base 5 when moving away from the base 5. The check ring 7 is in threaded connection with the telescopic rod 1, the check ring 7 is screwed up by a straight groove which is used for clamping the end face of the check ring 7 by a cross wrench, and the check ring is coated with thread glue for looseness prevention.
The electromagnet 4 is installed on the base 5, the permanent magnet 2 is installed on the telescopic rod 1, and when the telescopic rod 1 moves along the axial direction of the hole of the base 5, the electromagnet 4 and the permanent magnet 2 also move relatively. The magnetic pole at one end of the electromagnet 4 faces the magnetic pole at one end of the permanent magnet 2, and the electromagnet 4 and the permanent magnet 2 have the same polarity and are opposite to each other through current direction control when the buffer action is required, so that the repulsion force can be generated when the electromagnet 4 and the permanent magnet 2 are close to each other.
The whole buffering mechanism is fixed on a certain base of the airborne photoelectric detection device through 4 holes on the base 5. When the contact plate of telescopic link 1 is strikeed to the motion part that is cushioned, telescopic link 1 drives permanent magnet 2 and is close to electro-magnet 4, and the distance between electro-magnet 4 and permanent magnet 2 is more close, and the repulsion that produces is big more to play the effect of buffering. The size of the magnetic force of the electromagnet is changed by changing the current of the electromagnet 4, so that the size of the repulsive force between the electromagnet 4 and the permanent magnet 2 is adjusted, and the buffering capacity of the buffering mechanism is changed. When the moving part is stopped and the electromagnet 4 is de-energized, no repulsive force is generated between the electromagnet 4 and the permanent magnet 2, and thus no restoring force to be overcome is generated.
When the on-board photoelectric detection equipment breaks down to cause large impact on a moving part, the boss section on the telescopic rod 1 is firstly contacted with the base 5, so that the electromagnet 4 and the permanent magnet 2 cannot be continuously close to each other. This arrangement prevents the permanent magnet 2 from colliding with the electromagnet 4 to damage the mechanism when the external force is excessive.
Although embodiments of the present invention have been shown and described, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the principles and spirit of the present invention.
