Description

Technical Field

[0001] This utility model relates to the field of motor accessories technology, and more specifically, to a servo motor shock absorber housing assembly. Background Technology

[0002] Servo motors, due to their high precision and fast response, are widely used in industrial automation, CNC equipment, robotics, and other fields. The vibrations generated during motor operation can affect the positioning accuracy of equipment, shorten its lifespan, and produce noise. To suppress vibration transmission, a vibration-damping motor housing assembly is typically installed externally. This assembly uses an elastic structure to isolate the motor body from the external mounting base, thereby protecting the overall stable operation of the equipment.

[0003] However, most existing shock-absorbing motor housing assemblies adopt a fixed installation structure, and their installation interface is not adjustable. They cannot flexibly adapt to the different mounting hole spacing, spatial layout or mounting surface angle on the base of different equipment models. Specifically, when the motor needs to be installed on a non-standard or different model base, it is often necessary to customize a special housing or add a complex adapter bracket. In other words, the adaptability of its installation connection part needs to be improved.

[0004] In view of this, we propose a servo motor vibration damping motor housing assembly. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this utility model is to provide a servo motor vibration damping motor housing assembly to solve the problem mentioned in the background art that the installation compatibility of traditional servo motor vibration damping motor housing assemblies needs to be improved.

[0007] 2. Technical Solution

[0008] A servo motor shock absorber housing assembly includes a motor body and a connecting plate elastically connected to the bottom of the motor body by multiple springs. The elasticity between the connecting plate and the motor body can be preset and adjusted. Two movable plates are slidably connected to the bottom of the connecting plate in the length direction of the motor body. Movable blocks are slidably connected to both sides of the two movable plates in the width direction of the motor body. The movable blocks are provided with mounting slots for mounting the motor body.

[0009] Preferably, the bottom of the motor body is fixedly connected with a plurality of vertically arranged limiting rods, and the plurality of limiting rods are all arranged through the connecting plate.

[0010] Preferably, a rotating seat is rotatably connected to the bottom of the motor body, a screw is fixedly connected to the rotating seat, the screw passes through the connecting plate, and a threaded sleeve is connected to the screw through a ball screw thread, the threaded sleeve being fixedly connected to the connecting plate.

[0011] Preferably, the bottom of the motor body is fixedly connected to a plurality of sliding rods, the plurality of sliding rods are horizontally arranged, and the plurality of sliding rods are all arranged through the two movable plates.

[0012] Preferably, the slide bar has multiple threaded holes, which are used to fix the adjusted movable plate to the slide bar with screws.

[0013] Preferably, the movable plate has a movable groove for the movable block to move, and both sides of the movable block are fixedly connected to sliders with a T-shaped cross section. The movable groove has a sliding groove that matches the size of the movable groove.

[0014] Preferably, the opening direction of the movable groove and the slide is set along the width direction of the motor body.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. This utility model, through the coordinated action of a movable plate that slides along the length of the motor and a movable block that slides along the width, allows the position of the mounting slot to be adjusted arbitrarily in the horizontal plane, solving the problem of the traditional non-adjustable housing mounting interface. It can adapt to the different mounting hole spacing and spatial layout of different equipment bases without the need for customized adapter brackets, thus improving the adaptability of motor installation.

[0018] 2. This utility model drives the lifting and lowering of the screw sleeve by rotating the screw, which forces the connecting plate to move along the vertical slide bar, thereby presetting the deformation of the compression elastic element, so that the user can accurately adjust the initial stiffness and damping of the shock absorption system according to the specific working conditions such as equipment load requirements.

[0019] 3. This utility model uses a T-shaped slider embedded in a matching groove of the movable slot to form a directional sliding constraint along the width direction of the motor. This structure ensures smooth translation of the movable block while effectively resisting the torque and lateral force generated when the mounting bolts are tightened, preventing displacement and ensuring the installation reliability of the motor under dynamic working conditions.

[0027] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1-5 This utility model provides a technical solution:

[0030] A servo motor vibration damping housing assembly includes a motor body 1 and a connecting plate 2 elastically connected to the bottom of the motor body 1 by multiple springs 3. The elasticity between the connecting plate 2 and the motor body 1 can be preset and adjusted. Two movable plates 9 are slidably connected to the bottom of the connecting plate 2 in the length direction of the motor body 1. Movable blocks 11 are slidably connected to both sides of the two movable plates 9 in the width direction of the motor body 1. The movable blocks 11 are provided with mounting grooves 14 for mounting the motor body 1. This bidirectional sliding structure allows the mounting grooves 14 to be freely adjusted in the horizontal plane, thereby directly solving the problem of the non-adjustable mounting hole position of traditional housings. It can adapt to various mounting hole spacings without the need for customized adapter brackets, thus improving the adaptability of motor installation.

[0031] Secondly, the bottom of the motor body 1 is fixedly connected with multiple vertically arranged limiting rods 4, all of which are set through the connecting plate 2. This arrangement provides rigid guiding constraints for the elastic connection through the vertical limiting rods 4, forcibly restricting the connecting plate 2 to move only in the axial direction and preventing it from shifting.

[0032] Furthermore, a rotating seat 5 is rotatably connected to the bottom of the motor body 1, and a screw 6 is fixedly connected to the rotating seat 5. The screw 6 passes through the connecting plate 2, and a screw sleeve 7 is threadedly connected to the screw 6 through a ball screw pair. The screw sleeve 7 is fixedly connected to the connecting plate 2. With this arrangement, the elastic preload can be adjusted through the screw 6 and screw sleeve 7 mechanism, so that the damping stiffness of the damping housing can be adjusted according to the actual working conditions. The ball screw pair linearly converts the rotational motion into the displacement of the connecting plate 2. This adjustment method also improves the convenience of adjusting the damping stiffness.

[0033] Specifically, the bottom of the motor body 1 is fixedly connected with multiple slide rods 8. The multiple slide rods 8 are horizontally arranged and all of them pass through the two movable plates 9. This arrangement forms a double-rail guide system for the movable plates 9 through the horizontal slide rods 8, ensuring the smoothness of large-span sliding and allowing the movable plates 9 to be adjusted over a wider range.

[0034] In addition, the slide bar 8 is provided with multiple threaded holes 16. The threaded holes 16 are used to fix the adjusted movable plate 9 to the slide bar 8 by screws 15. This setting can fix the adjusted movable plate 9 and ensure the overall stability of the device.

[0035] Furthermore, the movable plate 9 has a movable groove 10 for the movement of the movable block 11. Both sides of the movable block 11 are fixedly connected to sliders 12 with a T-shaped cross-section. The movable groove 10 has a sliding groove 13 that matches the size of the movable groove 10. This arrangement makes the T-shaped sliders 12 and the sliding groove 13 mechanically interlocked to prevent the movable block 11 from shifting and to ensure the stability of the movable block 11 after it is connected to the motor base. In addition, the movable groove 10 and the sliding groove 13 are set along the width direction of the motor body 1. In specific implementation, a damper flush with the movable groove 10 can be set in the movable groove 10 to further ensure the stability of the movable block 11 in the sliding groove 13.

[0036] Working principle:

[0037] When installing the servo motor, first adjust the distance between the two movable plates 9 on the horizontal slide rod 8 along the length of the motor according to the actual distribution of the mounting holes on the equipment base, so that it covers the hole spacing requirements along the length of the base; then push each movable block 11 along the width of the motor so that its T-shaped slider 12 moves directionally within the slide groove 13 of the movable plate 9 until the mounting groove 14 on the movable block 11 is precisely aligned with the mounting hole position on the base. After adjustment, tighten the screw 15 to fix the movable plate 9 and the slide rod 8, and then fix the entire assembly to the equipment base through the mounting groove 14. At this time, rotating the screw 6 drives the screw sleeve 7 to rise and fall, which can preset the compression amount of the spring 3, and the vibration energy generated by the motor during operation is buffered and absorbed by the spring 3 and the connecting plate 2.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
