[0002] The servo motor is a motor widely used in various fields and occasions. It has the advantages of high precision, high speed, and high torque. Therefore, it is widely used in industrial automation, medical equipment, aerospace, military equipment and other fields. When the servo motor is working, it will generate vibration, and the vibration elimination structure ensures the normal operation of the servo motor.
[0003] The servo motor is usually fixed to the equipment body by bolts. When the servo motor is working, it will generate vibration due to its high-speed operation. Some existing servo motor vibration elimination usually uses buffer shock absorbers or damping springs. Since the buffer shock absorbers or damping springs are basically rigidly connected to the servo motor housing, the vibration generated by the servo motor will be transmitted to the external housing of the servo motor through the rigid connection, causing the external housing of the servo motor to vibrate. Long-term vibration of the servo motor housing may cause the fixing screws on the surface of the servo motor housing to loosen, thereby causing the servo motor to shake, which is very prone to failure during operation. In severe cases, it may also cause wear or breakage of the rotating shaft. Summary of the invention

[0026] S2: Water is pushed into the second buffer through the cross pipe. At this time, the water pressure pushes the second push plate to move toward the surface of the motor body. The movement of the second push plate drives the second guide rod and the second top plate to move toward the surface of the motor body to squeeze the second spring, so that the second top plate contacts the motor body.
[0027] S3: The force of the motor body squeezing the first top plate drives the second push plate to move toward the surface of the motor body through water, so that the second top plate has a reaction force acting on the surface of the motor body. As the motor body continues to squeeze the cross tube, the third spring is compressed, so that the vibration generated by the motor body is eliminated.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] 1) When the servo motor with a vibration elimination structure is in use, the vibration of the motor body will squeeze the first top plate to move into the first buffer, and the movement of the first top plate will drive the movement of the first guide rod and the first push plate, and the movement of the first push plate will push the water in the first buffer to move, and the water will be pushed into the inside of the second buffer through the cross tube. At this time, the water pressure pushes the second push plate to move toward the surface of the motor body, and the movement of the second push plate drives the second guide rod and the second top plate to move toward the surface of the motor body. The force of the motor body squeezing the first top plate causes the second top plate to have a reaction force acting on the surface of the motor body through the water, and the motor body continues to squeeze the cross tube to compress the third spring, thereby realizing the elimination of the vibration generated by the motor body. The vibration generated by the motor body will not be transmitted to the outer casing, thereby preventing the bolts on the surface of the outer casing from loosening, ensuring the normal operation of the servo motor, and thereby extending the service life of the servo motor.
[0030] 2) When the servo motor with a vibration elimination structure is in use, the movement of the first push plate pushes the water in the first buffer to move, and the water is pushed into the second buffer through the cross tube. At this time, the water pressure pushes the second push plate to move and then drives the second top plate to move toward the surface of the motor body. The motor body first squeezes the trigger rod to move into the second guide rod. The second guide rod is a hollow tube. The movement of the trigger rod opens the second sealing plate and the first sealing plate, and the water inside the second buffer enters the second guide rod. The water then passes through the through hole. Since the water has pressure during movement, a small amount of water is sprayed out through the end of the trigger rod and a large amount of water is sprayed out through the slot. The sprayed water falls on the surface of the motor body, thereby cooling the motor body.
[0031] 3) When the servo motor with a vibration elimination structure is in use, the movement of the first push plate pushes the water in the first buffer to move, and the water is pushed to the inside of the second buffer through the cross tube. At this time, the water pressure pushes the second push plate to move and then drives the second top plate to move toward the surface of the motor body, and the extrusion trigger rod moves to drive the second sealing plate to move and then stretch the fourth spring. Since a rubber pad is provided on the surface of the second top plate, the vibration generated by the motor body is further eliminated, further ensuring the normal operation of the servo motor.

The trigger rod 19 is a hollow rod, and a plurality of through holes 23 are provided on the surface of the trigger rod 19. The movement of the trigger rod 19 opens the second sealing plate 21 and the first sealing plate 22, and the water inside the second buffer 7 enters the second guide rod 13, and the water passes through the through hole 23. Since the water has pressure during the movement, a small amount of water is sprayed out through the end of the trigger rod 19, and a large amount of water is sprayed out through the groove 20.

[0048] The use steps of the present invention are as follows: when the servo motor with a vibration elimination structure is in use, heat is generated during the operation of the motor body 1. When the motor body 1 is static, the second sealing plate 21 matches the second guide rod 13 to achieve sealing. The first sealing plate 22 is in an open state. The vibration generated by the operation of the motor body 1 causes the motor body 1 to squeeze the first top plate 10 to move into the first buffer 6. The movement of the first top plate 10 drives the first guide rod 9 and the first push plate 11 to move and stretch the first spring 12. The movement of the first push plate 11 pushes the water in the first buffer 6 to move. The water is pushed into the second buffer 7 through the cross pipe 5.

Since the water has pressure during movement, a small amount of water is sprayed out through the end of the trigger rod 19, and a large amount of water is sprayed out through the slot 20. The sprayed water falls on the surface of the motor body 1, thereby cooling the motor body 1. The firing rod 19 continues to be squeezed, and at this time the first sealing plate 22 moves to match and seal with the slot 20, prohibiting water from spraying out of the slot 20, thereby preventing excessive pressure relief inside the second buffer 7. When the second buffer 7 and the first buffer 6 are reset, the micro water pump 27 is turned on to pump water out of the water tank 26 through the connecting pipe 29, through the one-way valve 31, and then through the outlet pipe 30 into the water supply pipe 25, and the water supply pipe 25 then replenishes water to the inside of the cross pipe 5. This solution promotes the movement of water in the first buffer 6 by the movement of the first push plate 11, and the water is pushed to the inside of the second buffer 7 through the cross pipe 5. At this time, The water pressure pushes the second push plate 14 to move and then drives the second top plate 16 to move toward the surface of the motor body 1. The motor body 1 first squeezes the trigger rod 19 to move toward the second guide rod 13. The second guide rod 13 is a hollow tube. The movement of the trigger rod 19 opens the second sealing plate 21 and the first sealing plate 22. The water inside the second buffer 7 enters the second guide rod 13, and the water then passes through the through hole 23. Since the water has pressure during movement, a small amount of water is sprayed out through the end of the trigger rod 19, and a large amount of water is sprayed out through the slot 20. The sprayed water falls on the surface of the motor body 1, thereby cooling the motor body 1.

The water pressure pushes the second push plate 14 to move and then drives the second top plate 16 to move toward the surface of the motor body 1, squeezing the trigger rod 19 to move and drive the second sealing plate 21 to move and then stretch the fourth spring 24. Since the surface of the second top plate 16 is provided with a rubber pad 32, the vibration generated by the motor body 1 is further eliminated, and the normal operation of the servo motor is further guaranteed.
[0050] The two ends of the fourth spring 24 are fixedly connected to the second sealing plate 21 and the mounting plate 18 respectively. The second sealing plate 21 is elastically connected to the mounting plate 18 through the fourth spring 24. The second sealing plate 21 is reset by the fourth spring 24 to seal the second guide rod 13, thereby preventing water inside the second buffer 7 from entering the second guide rod 13.
[0051] The use steps of the present invention are as follows: when the servo motor with a vibration elimination structure is in use, the first push plate 11 moves to push the water in the first buffer 6, and the water is pushed to the inside of the second buffer 7 through the cross tube 5. At this time, the water pressure pushes the second push plate 14 to move, thereby driving the second top plate 16 to move toward the surface of the motor body 1, and the extrusion trigger rod 19 moves to drive the second sealing plate 21 to move, thereby stretching the fourth spring 24. Since the surface of the second top plate 16 is provided with a rubber pad 32, the vibration generated by the motor body 1 is further eliminated, thereby further ensuring the normal operation of the servo motor.
[0052] Working principle: When eliminating the vibration generated during the operation of the servo motor, the vibration generated by the operation of the motor body 1, the motor body 1 will squeeze the first top plate 10 to move into the first buffer 6, the movement of the first top plate 10 drives the first guide rod 9 and the first push plate 11 to move and stretch the first spring 12, the movement of the first push plate 11 drives the water in the first buffer 6 to move, and the water is pushed to the inside of the second buffer 7 through the cross tube 5, at this time, the water pressure pushes the second push plate 14 to move toward the surface of the motor body 1, the movement of the second push plate 14 drives the second guide rod 13 and the second top plate 16 to move toward the surface of the motor body 1 to squeeze the second spring 15, so that the second top plate 16 contacts the motor body 1, the motor body 1 squeezes the first top plate 10, and the second push plate 14 is pushed by water to move and drive the second guide rod 13 and the second top plate 16 to move toward the surface of the motor body 1, so that the second top plate 16 has a reaction force acting on the surface of the motor body 1, as the motor body 1 continues to squeeze the cross tube 5 to compress the third spring 17, so that the vibration generated by the motor body 1 is eliminated;
[0053] During the operation of the motor body 1, heat is generated. When static, the second sealing plate 21 matches the second guide rod 13 to achieve sealing. The first sealing plate 22 is in an open state. The vibration generated by the operation of the motor body 1 will squeeze the first top plate 10 to move into the first buffer 6. The movement of the first top plate 10 drives the first guide rod 9 and the first push plate 11 to move and stretch the first spring 12. The movement of the first push plate 11 pushes the water in the first buffer 6 to move. The water is pushed into the second buffer 7 through the cross tube 5. At this time, the water pressure pushes the second push plate 14 to move and then drives the second top plate 16 to move toward the surface of the motor body 1. The motor body 1 first squeezes the trigger rod 19 to move into the second guide rod 13. The second guide rod 13 is a hollow tube. The movement of the trigger rod 19 makes the second sealing plate 21 and the first The sealing plate 22 is opened, and the water inside the second buffer 7 enters the second guide rod 13, and then passes through the through hole 23. Since the water has pressure during movement, a small amount of water is sprayed out through the end of the trigger rod 19, and a large amount of water is sprayed out through the slot 20. The sprayed water falls on the surface of the motor body 1, thereby cooling the motor body 1. As the trigger rod 19 continues to be squeezed, the first sealing plate 22 moves to match the slot 20 for sealing, and the water at the slot 20 is prohibited from spraying out, thereby preventing excessive pressure relief inside the second buffer 7. When the second buffer 7 and the first buffer 6 are reset, the micro water pump 27 is turned on to pump the water in the water tank 26 through the connecting pipe 29, through the one-way valve 31, and then through the water outlet pipe 30 into the water supply pipe 25, and the water supply pipe 25 then replenishes water to the inside of the cross pipe 5;
[0054] The movement of the first push plate 11 pushes the water in the first buffer 6 to move, and the water is pushed into the second buffer 7 through the cross tube 5. At this time, the water pressure pushes the second push plate 14 to move, thereby driving the second top plate 16 to move toward the surface of the motor body 1, squeezing the trigger rod 19 to move, driving the second sealing plate 21 to move, and then stretching the fourth spring 24. Since the surface of the second top plate 16 is provided with a rubber pad 32, the vibration generated by the motor body 1 is further eliminated.
[0055] A method for eliminating vibration of a servo motor, the steps of which are as follows:
[0056] S1: The motor body 1 generates vibration when working, and the motor body 1 squeezes the first top plate 10 to move into the first buffer 6. The movement of the first top plate 10 drives the first guide rod 9 and the first push plate 11 to move and stretch the first spring 12. The movement of the first push plate 11 pushes the water in the first buffer 6 to move;
[0057] S2: Water is pushed into the second buffer 7 through the cross tube 5. At this time, the water pressure pushes the second push plate 14 to move toward the surface of the motor body 1. The movement of the second push plate 14 drives the second guide rod 13 and the second top plate 16 to move toward the surface of the motor body 1 to squeeze the second spring 15, so that the second top plate 16 contacts the motor body 1.
[0058] S3: The force of the motor body 1 squeezing the first top plate 10 pushes the second push plate 14 through water to drive the second guide rod 13 and the second top plate 16 to move toward the surface of the motor body 1, so that the second top plate 16 has a reaction force acting on the surface of the motor body 1. As the motor body 1 continues to squeeze the cross tube 5, the third spring 17 is compressed, so that the vibration generated by the motor body 1 is eliminated.
