Abstract
Description
Technical Field
[0001] The invention belongs to the field of automatic control of electric motors, and in particular relates to a buffer switching positioning structure of an electric motor and a positioning method thereof. Background Art
[0002] An electric motor is a device that converts electrical energy into mechanical energy and is usually used to drive various mechanical equipment, such as pumps, fans, washing machines, etc. Its working principle is to generate a magnetic field by passing current through a coil, thereby causing the rotor to rotate. The motor will generate vibrations during operation, so it is generally necessary to use a shock-absorbing device for buffering and shock reduction to prevent vibration impact from damaging the connecting parts. The existing shock-absorbing method generally uses elastic parts such as springs or rubber rods for buffering and shock reduction. When the spring or rubber rod is buffering, the elastic performance of the spring or rubber rod will be reduced after a certain period of pressure, thereby reducing the buffering and shock-absorbing effect. The tiny vibrations that sometimes occur during the operation of the motor can actually be eliminated by pressing and fixing, while larger floating vibrations need to be pressed and buffered by elastic parts. For this reason, the structure can be upgraded and designed to achieve reasonable adjustment of different vibration levels and improve the stability of the structure. Summary of the invention
[0003] In view of the above-mentioned deficiencies of the prior art, the present invention solves the problem of providing a motor buffer switchable positioning structure and a positioning method thereof which can realize switching operation structures with different vibration degrees.
[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A buffer switch positioning structure for an electric motor comprises a positioning base, a motor housing, and a switching positioning assembly; the motor housing is mounted on the upper side of the positioning base; the switching positioning assembly comprises a buffer positioning sleeve, a clamping positioning sleeve, a buffer movable plate, a clamping movable plate, a buffer elastic column, a clamping plug-in column, and a power unit; a plurality of buffer positioning sleeves and a clamping positioning sleeve are respectively mounted on the front and rear sides of the motor housing; a buffer movable plate and a clamping movable plate are respectively mounted on the front and rear sides of the positioning base, and the buffer movable plate and the clamping movable plate are slidably connected to the positioning base forward and backward; a plurality of buffer elastic columns are mounted on the inner side of the buffer movable plate; a plurality of clamping plug-in columns are mounted on the inner side of the clamping movable plate; the power unit is mounted on one side of the positioning base; the power unit drives the buffer movable plate and the clamping movable plate to move relative to each other, and causes the clamping plug-in column to be inserted and pressed into the clamping positioning sleeve or causes the buffer elastic column to be pressed into the buffer positioning sleeve.
[0005] Furthermore, a controller is provided on one side of the positioning base; a clamping pressure sensor is provided at the inner end of the clamping plug column; a buffering pressure sensor is provided at the inner end of the buffering elastic column; and the controller is connected to the clamping pressure sensor, the buffering pressure sensor, and the power unit signal.
[0006] Furthermore, a rotating guide rod is provided at the upper end of the positioning base; both ends of the rotating guide rod are connected to the end of a buffer movable plate and a clamp movable plate; the power unit is a driving motor; one end of the driving motor is connected to the rotating guide rod through the forward and reverse rotation drive of the power shaft and causes the buffer movable plate and the clamp movable plate to move relative to each other.
[0007] Furthermore, a buffer plate external thread section and a clamping plate external thread section are respectively provided at both ends of the rotating guide rod; the threads of the buffer plate external thread section and the clamping plate external thread section are relatively distributed; a buffer movable sleeve is provided at the end of the buffer movable plate; a clamping movable sleeve is provided at the end of the clamping movable plate; the buffer movable sleeve is threadedly screwed on the buffer plate external thread section; the clamping movable sleeve is threadedly screwed on the clamping plate external thread section.

[0009] Furthermore, the buffer elastic column is a cylindrical spring or a rubber rod.

At this time, there is no pressing force between the buffer elastic column and the buffer positioning sleeve. When the motor is driven, the vibration is enhanced. At this time, a clamping pressure sensor located at the inner end of the clamping plug-in column senses the pressure. When the pressure reaches a preset value, a signal is transmitted to a controller, and the controller drives a power unit to start. The power unit drives a buffer movable plate to move toward a motor housing, and the buffer movable plate drives the buffer elastic column to press against the buffer positioning sleeve. The pressing and buffering is realized in the positioning sleeve, and at the same time, the power unit drives the clamping movable plate to move away from the motor housing, and makes the clamping plug-in column separate from the clamping positioning sleeve to prevent the clamping positioning sleeve from vibrating with the motor housing and causing damage to the clamping plug-in column and the clamping positioning sleeve; when the motor is driven, the vibration is weakened, and at this time the buffering pressure sensor at the inner end of the buffering elastic column transmits a signal to the controller, and the controller controls the power unit to drive the buffering movable plate and the clamping movable plate to move again, and makes the buffering elastic column extend outward and no longer press against the buffer positioning sleeve, and at the same time makes the clamping plug-in column inserted into the clamping positioning sleeve to realize positioning, and so on.
