Description

Technical Field

[0001] The invention belongs to the technical field of servo motors, and in particular relates to a servo motor with a vibration reduction and protection mechanism. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed changer. The servo motor can control speed and has very accurate position accuracy. It can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque.

The utility model provides a bottom shock absorbing component at the bottom of the placement table through the arrangement of the placement table and the buckle seat, which can support the bottom of the motor, and when subjected to external pressure, the placement table will squeeze the connecting column to move, so that the third spring and the second spring will contract, thereby achieving a shock absorbing effect, and through the arrangement of the side shock absorbing component, when the servo motor encounters external force shaking, the support column causes the mounting barrel to contract, thereby achieving a shock absorbing effect.

When the servo motor may encounter vibrations in different directions during operation, the vibration cannot be eliminated in all directions. Summary of the invention

[0005] The embodiment of the present invention provides a servo motor with a vibration reduction and protection mechanism to solve the problems in the prior art.

[0006] The embodiment of the present invention adopts the following technical scheme: a servo motor with a vibration reduction and protection mechanism comprises an installation box, a horizontally arranged servo motor is arranged in the installation box, a bottom vibration reduction structure for reducing vibration of the servo motor is arranged at the bottom of the servo motor, the servo motor is installed on the bottom vibration reduction structure, side wall vibration reduction structures are arranged on both sides of the servo motor, the side wall vibration reduction structures reduce vibration on both sides of the servo motor, a rear vibration reduction structure is also arranged at the rear of the servo motor, and the rear vibration reduction structure is connected to the rear of the installation box to reduce vibration of the servo motor.

[0007] When the servo motor is subjected to vibration reduction in the present invention, the jitter generated by the operation of the servo motor can be eliminated and vibration reduced in multiple directions at the same time.

[0008] According to a further technical solution, two mounting rings are sleeved on the servo motor, the two mounting rings are symmetrically arranged on the servo motor, the mounting rings are detachably connected to each other, and a horizontally arranged mounting plate is provided at the bottom of the two mounting rings.

[0009] A further technical solution is that the bottom vibration reduction structure includes a mounting seat connected to the bottom of the mounting box, a connecting plate is provided on the mounting seat, the middle position of the connecting plate is rotatably connected to the mounting seat, a turntable is provided at one end of the connecting plate, a connecting spring connected to the mounting seat is provided at the other end of the connecting plate, a rotating shaft is provided on the mounting seat, a rotating plate is provided at one end of the rotating shaft, a circular groove is provided on the rotating plate, the turntable rotates in the circular groove on the rotating plate, a bearing plate is provided at the other end of the rotating shaft, and the bearing plate is connected to the mounting plate.

[0014] According to a further technical solution, a protective vibration-damping sponge is provided above the servo motor in the installation box.

[0015] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] Firstly, when the servo motor is subjected to vibration reduction in the present invention, the jitter generated by the servo motor can be eliminated and vibration reduced in multiple directions at the same time. Since the output shaft of the servo motor may encounter pauses or obstructions during operation, the servo motor will generate jitter, and the direction and position of the jitter are difficult to predict and calculate. Therefore, during use, the bottom vibration reduction structure and the two side wall vibration reduction structures can be used to eliminate the jitter generated by the servo motor in an all-round manner, so that the servo motor can rotate more smoothly.

[0017] Secondly, when the present invention eliminates the jitter at the bottom of the servo motor, the jitter generated by the servo motor is transmitted to the supporting plate, causing the supporting plate to slightly shake on the mounting seat through the rotating shaft, thereby driving the connecting plate to rotate. The rotation of the connecting plate will squeeze the turntable downward, and the position of the connecting plate will shift, causing the connecting plate to rotate on the mounting seat. Due to the presence of a connecting spring on the connecting plate, the connecting spring is stretched during the rotation of the connecting plate. During this process, the connecting spring needs to be reset so that the supporting plate is in a balanced state. When the supporting plate shakes slightly, the generated vibration will be eliminated, so that the supporting plate is always in a balanced and horizontal state, ensuring the operation of the servo motor. The jitter generated at the bottom of the servo motor can be reduced and eliminated through the bottom vibration reduction structure.

[0018] Thirdly, when the present invention eliminates the left and right vibrations of the servo motor, the vibrations will drive the two sliding rods on the sliding plate to slide on the connecting seat, and the sliding rods will be compressed by the return springs at the bottom of the mounting plate, thereby eliminating the generated vibrations. In the process of eliminating and reducing vibrations, the generated vibrations are eliminated by the sliding of the sliding rods on the connecting seat and the compression of the return springs, thereby eliminating and reducing the left and right vibrations generated by the servo motor, thereby ensuring the smooth operation of the servo motor.

[0019] Fourthly, when the rear part of the servo motor is deviated in the present invention, the vibration generated is deviated and eliminated by the deviating spring and the deviating damper, and the deviating pad can also be pressed against the rear part of the servo motor so that the deviating pad will not fall off.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figures 1 to 6 As shown, an embodiment of the present invention provides a servo motor with a vibration reduction and protection mechanism, including an installation box 1, wherein a horizontally arranged servo motor 2 is arranged in the installation box 1, and a bottom vibration reduction structure 3 for reducing vibration of the servo motor 2 is arranged at the bottom of the servo motor 2, and the servo motor 2 is installed on the bottom vibration reduction structure 3, and side wall vibration reduction structures 4 are arranged on both sides of the servo motor 2, and the side wall vibration reduction structures 4 reduce vibration on both sides of the servo motor 2, and a rear vibration reduction structure 5 is further arranged at the rear of the servo motor 2, and the rear vibration reduction structure 5 is connected to the rear of the installation box 1 to reduce vibration of the servo motor 2, and a plurality of heat dissipation holes are arranged at the bottom of the installation box 1, and the plurality of heat dissipation holes can dissipate heat from the servo motor 2 and discharge heat outward through the heat dissipation holes.

[0032] The servo motor 2 will generate a lot of vibration when working, and the vibration needs to be eliminated and weakened. At this time, the up and down shaking generated by the servo motor 2 is eliminated and reduced by the bottom vibration reduction structure 3, and the left and right shaking generated by the servo motor 2 is eliminated by the two side wall vibration reduction structures 4, so that the vibration reduction effect is better, and the rear vibration reduction structure 5 can also support the servo motor 2 and perform vibration reduction on the rear of the servo motor 2.

[0033] In this embodiment, two mounting rings 21 are sleeved on the servo motor 2 , and the two mounting rings 21 are symmetrically arranged on the servo motor 2 . The mounting rings 21 are detachably connected to each other, and a horizontally arranged mounting plate 22 is provided at the bottom of the two mounting rings 21 .

[0034] The two mounting rings 21 can be used to fix the position of the servo motor 2, and the bottom mounting plate 22 can bear and support the servo motor 2. When installing the mounting rings 21, the mounting ring 21 located at the lower part can be connected to the servo motor 2 first, and then the two side wall vibration reduction structures 4 can be connected to the mounting ring 21 located at the upper part through bolts 47, so as to support the servo motor 2.

[0035] In this embodiment, the bottom vibration damping structure 3 includes a mounting seat 31 connected to the bottom of the mounting box 1, and a connecting plate 32 is provided on the mounting seat 31. The middle position of the connecting plate 32 is rotatably connected to the mounting seat 31, and a turntable 33 is provided at one end of the connecting plate 32, and a connecting spring 34 connected to the mounting seat 31 is provided at the other end of the connecting plate 32. A rotating shaft 35 is provided on the mounting seat 31, and a rotating plate 36 is provided at one end of the rotating shaft 35. A circular groove is provided on the rotating plate 36, and the turntable 33 rotates in the circular groove on the rotating plate 36. A bearing plate 37 is provided at the other end of the rotating shaft 35, and the bearing plate 37 is connected to the mounting plate 22.

[0036] When eliminating the jitter at the bottom of the servo motor 2, the jitter generated by the servo motor 2 is transmitted to the supporting plate 37, so that the supporting plate 37 shakes slightly on the mounting seat 31 through the rotating shaft 35, thereby driving the connecting plate 32 to rotate. The rotation of the connecting plate 32 will squeeze the turntable 33 downward, and the position of the connecting plate 32 will be offset, so that the connecting plate 32 rotates on the mounting seat 31. Due to the presence of a connecting spring 34 on the connecting plate 32, the connecting spring 34 is stretched during the rotation of the connecting plate 32. During this process, the connecting spring 34 needs to be reset so that the supporting plate 37 is in a balanced state. When the supporting plate 37 shakes slightly, the generated vibration will be eliminated, so that the supporting plate 37 is always in a balanced and horizontal state, ensuring the operation of the servo motor 2. The bottom vibration reduction structure 3 can be used to reduce and eliminate the jitter generated at the bottom of the servo motor 2.

[0037] In this embodiment, the side wall vibration reduction structure 4 includes a connecting seat 41 and a sliding plate 42. The connecting seat 41 is connected to the side wall of the installation box 1. A reset spring 43 is provided in the middle position of the connecting seat 41. A mounting plate 44 is provided on the reset spring 43. The sliding plate 42 is connected to the side wall of the mounting ring 21. Two sliding rods 45 are provided on the sliding plate 42. The sliding rods 45 are slidably matched with the connecting seat 41. A sliding rod 46 is provided in the middle position of the sliding plate 42. The sliding rod 46 is connected to the mounting plate 44.

[0038] When eliminating the left and right jitter of the servo motor 2, after the jitter is generated, the two sliding rods 45 on the sliding plate 42 are driven to slide on the connecting seat 41, and the sliding rod 46 is compressed by the return spring 43 at the bottom of the mounting plate 44, thereby eliminating the generated jitter. In the process of eliminating and reducing vibration, the generated jitter is eliminated by sliding the sliding rod 45 on the connecting seat 41 and compressing the return spring 43, so that the left and right jitter generated by the servo motor 2 can be eliminated and the vibration is reduced, thereby ensuring the smooth operation of the servo motor 2.

[0039] In this embodiment, two bolts 47 are disposed on the sliding plate 42 , and the sliding plate 42 is connected to the mounting ring 21 via the bolts 47 .

[0040] In this embodiment, a vibration-damping pad 6 is provided at the rear of the servo motor 2, and the vibration-damping pad 6 is a hexagonal hollow structure; the vibration-damping pad 6 can reduce vibration at the rear of the servo motor 2, and the hollow structure can achieve a better vibration reduction effect during vibration reduction, and can also silence and dissipate heat for the servo motor 2.

[0041] In this embodiment, the rear vibration reduction structure 5 includes a first mounting circular plate 51 and a second mounting circular plate 52, a vibration reduction spring 53 and a vibration reduction damper 54 are provided between the first mounting circular plate 51 and the second mounting circular plate 52, and the first mounting circular plate 51 and the second mounting circular plate 52 are connected between the vibration reduction pad 6 and the rear wall of the mounting box 1.

[0042] When the rear part of the servo motor 2 is subjected to vibration reduction, the vibration generated is reduced and eliminated by the vibration reduction spring 53 and the vibration reduction damper 54. The vibration reduction pad 6 can also be pressed against the rear part of the servo motor 2 so that the vibration reduction pad 6 will not fall off.

[0043] In the present invention, when the servo motor 2 is subjected to vibration reduction, the jitter generated by the servo motor 2 can be eliminated and vibration reduced in multiple directions at the same time. Since the output shaft of the servo motor 2 may encounter a pause or obstruction during operation, the servo motor 2 will generate jitter, and the direction and position of the jitter are difficult to predict and calculate. Therefore, during use, the bottom vibration reduction structure 3 and the two side wall vibration reduction structures 4 can be used to eliminate the jitter generated by the servo motor 2 in all directions, so that the servo motor 2 can rotate more smoothly and smoothly.

[0044] In this embodiment, a protective vibration-damping sponge is provided above the servo motor 2 in the installation box 1. The protective vibration-damping sponge can fill the gap between the installation box 1 and the servo motor 2, perform vibration reduction operations above the servo motor 2, and reduce and eliminate upward vibration.

[0045] A bottom vibration reduction structure 3 is provided on the installation box 1, and the bottom vibration reduction structure 3 can eliminate and reduce the up and down vibrations generated by the servo motor 2 during operation, thereby reducing the noise caused by mechanical vibration and improving the reliability and stability of the machine.

[0047] The rear vibration reduction structure 5 can support the servo motor 2 and can reduce vibration at the rear thereof, thereby improving the stability of the machine and ensuring the safety of the machine.

[0048] Through the coordinated use of the bottom vibration reduction structure 3 and the side wall vibration reduction structure 4, various vibrations generated by the servo motor 2 during operation can be eliminated and reduced more effectively, thereby further improving the reliability and stability of the machine.
