Description

Technical Field

[0001] This utility model relates to the field of servo drive anti-vibration technology, and specifically discloses an anti-vibration device for servo drives. Background Technology

[0002] Servo drives are widely used in industrial automation equipment, but mechanical vibration and shock can easily damage electronic components and reduce accuracy.

[0003] A shockproof device for a servo drive, disclosed in Chinese Patent No. CN222255830U, includes a protective housing with a support plate inside. The servo drive body is mounted on the top of the support plate, and a first spring is fixed to the bottom of each support plate. The end of each first spring away from the support plate is fixed to the inner wall of the protective housing. A first damper is installed within each first spring between the protective housing and the support plate. A fixing block is fixed to the bottom of the protective housing, and a base plate is located below the fixing block. By rotating a rotating plate, the user rotates a connecting column, which in turn rotates a bidirectional screw, causing two moving plates to move towards each other under the limitation of a limiting column. This, in turn, causes two clamping plates to move towards each other, allowing the modified assembly to be clamped and installed in a specific location. Furthermore, the mounting plate and mounting holes allow for screw installation even when clamping is restricted, enhancing practicality.

[0004] The above-mentioned device still has the following problems during use:

[0005] (1) Using only a single spring or rubber pad is difficult to suppress high-frequency vibration and low-frequency impact at the same time, and the shock absorption effect is limited.

[0006] (2) It is difficult to replace the shock-absorbing components after they are damaged, and there is a lack of modular design.

[0007] (3) Fixed installation structure cannot be adapted to servo drives of different sizes.

[0008] Therefore, a shockproof device for servo drives is needed to solve the above problems. Utility Model Content

[0009] This utility model proposes a shockproof device for a servo driver. The composite layer design can reduce the vibration transmission rate and improve the shock absorption effect. The installation components can be easily disassembled and maintained, and different specifications of drivers can be installed by adjusting the components.

[0010] This utility model is implemented as follows: a shockproof device for a servo driver includes a driver body, a shockproof component is disposed below the driver body, and a mounting component is disposed on the outer wall of the shockproof component.

[0011] The shock-absorbing component includes a polyurethane foam layer, a metal honeycomb panel at the lower end of the polyurethane foam layer, and a silicone damping pad at the lower end of the metal honeycomb panel.

[0012] The installation assembly includes an upper support frame and a lower support frame with a "U" shaped structure. Vertical plates are fixedly connected to both ends of the polyurethane foam layer and the silicone damping pad. Rectangular grooves are opened on the outer walls of multiple vertical plates. Sliding grooves are opened on both ends of the upper and lower support frames. Screws extending into the sliding grooves are threaded through and threaded to both ends of the upper and lower support frames. One end of multiple screws is rotatably connected to a locking block that matches the rectangular groove.

[0013] An adjustment component is provided above the upper support frame.

[0014] As a preferred anti-vibration device for a servo driver according to this utility model, the adjustment assembly includes two left and right distributed mounting plates fixedly connected to the upper end face of the upper support frame. The outer walls of the two mounting plates are both threaded and threaded with threaded rods. The opposite sides of the two threaded rods are rotatably connected to L-shaped plates. The inner walls of the two L-shaped plates are provided with threaded positioning holes. The mounting hole of the driver body is detachably connected to the two L-shaped plates by bolts.

[0015] As a preferred anti-vibration device for a servo driver according to this utility model, the lower end surfaces of both L-shaped plates are in contact with the upper end surface of the upper support frame.

[0016] As a preferred anti-vibration device for a servo drive according to this utility model, the outer walls of the polyurethane foam layer, metal honeycomb panel, silicone damping pad, upper support frame and lower support frame are all provided with multiple vertically aligned ventilation holes.

[0017] As a preferred anti-vibration device for a servo driver according to this utility model, a thermally conductive silicone pad is provided at the upper end of the upper support frame.

[0018] As a preferred anti-vibration device for a servo drive according to this utility model, the polyurethane foam layer, the metal honeycomb panel, and the silicone damping pad are bonded and fixed together by epoxy resin adhesive.

[0019] The beneficial effects of this utility model are:

[0020] (1) The composite shock absorption component consisting of polyurethane foam layer, polyurethane foam layer and silicone damping pad can reduce the vibration transmission rate and protect precision electronic components.

[0021] (2) Quick installation and precise fit: the screw drive block is embedded in the rectangular slot of the vertical plate, which can quickly complete the fixing and disassembly of the shock-absorbing components and facilitate the replacement and maintenance of the shock-absorbing components after damage.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0030] Please see Figure 1-4 A shockproof device for a servo driver includes a driver body 12, a shockproof component is disposed below the driver body 12, and a mounting component is disposed on the outer wall of the shockproof component.

[0031] The shock-absorbing component includes a polyurethane foam layer 3, a metal honeycomb panel 4 at the lower end of the polyurethane foam layer 3, and a silicone damping pad 5 at the lower end of the metal honeycomb panel 4.

[0032] The mounting components include an upper support frame 1 and a lower support frame 2 with a "U" shaped structure. Vertical plates 6 are fixedly connected to both ends of the polyurethane foam layer 3 and the silicone damping pad 5. Rectangular grooves 10 are opened on the outer walls of multiple vertical plates 6. Sliding grooves 7 are opened on both ends of the upper support frame 1 and the lower support frame 2. Screws 8 extending into the sliding grooves 7 are threaded through and threaded to both ends of the upper support frame 1 and the lower support frame 2. One end of multiple screws 8 is rotatably connected to a locking block 9 that is adapted to the rectangular groove 10.

[0033] An adjustment component is provided above the upper support frame 1.

[0034] In this embodiment: the high-frequency mechanical vibration generated by the driver body 12 is quickly absorbed by the polyurethane foam layer 3 through material deformation. The honeycomb structure disperses the local impact force to the entire plane to prevent stress concentration. The metal honeycomb panel 4 is combined with the polyurethane foam layer 3 to suppress the resonance frequency. The low-frequency vibration transmitted from outside the equipment is dissipated by the viscoelasticity of the silicone damping pad 5, reducing the vibration transmission rate.

[0035] The shock-absorbing component is placed in the space formed by the upper support frame 1 and the lower support frame 2. The rectangular groove 10 of the vertical plate 6 is aligned with the slide groove 7 of the support frame. The screw 8 is rotated to push the locking block 9 to move horizontally along the slide groove 7. The locking block 9 is embedded in the rectangular groove 10 of the vertical plate 6 to achieve the lateral locking of the shock-absorbing component.

[0036] Different models of driver bodies 12 can be installed by adjusting the components.

[0037] As a technical optimization of this utility model, the adjustment component includes two left and right distributed mounting plates 13 fixedly connected to the upper end face of the upper support frame 1. The outer walls of the two mounting plates 13 are both threaded and threaded with threaded rods 14. The opposite sides of the two threaded rods 14 are rotatably connected with L-shaped plates 15. The inner walls of the two L-shaped plates 15 are provided with threaded positioning holes 16. The mounting holes of the driver body 12 are detachably connected to the two L-shaped plates 15 by bolts.

[0038] In this embodiment: Rotate the threaded rods 14 on both sides. Rotating counterclockwise moves the L-shaped plate 15 toward the center, while rotating clockwise moves it in the opposite direction. The L-shaped plate 15 slides horizontally, so that the threaded positioning hole 16 on the inner wall of the L-shaped plate 15 corresponds to the mounting hole of the driver body 12. The driver body 12 is connected to the threaded positioning hole 16 of the L-shaped plate 15 by bolts passing through its mounting hole, thus completing the installation of the driver body 12.

[0039] As a technical optimization of this utility model, the lower end surfaces of the two L-shaped plates 15 are both in contact with the upper end surface of the upper support frame 1.

[0040] In this embodiment, the lower end faces of both L-shaped plates 15 are in contact with the upper end face of the upper support frame 1, which can prevent the L-shaped plates 15 from rotating axially.

[0041] As a technical optimization of this utility model, the outer walls of the polyurethane foam layer 3, the metal honeycomb panel 4, the silicone damping pad 5, the upper support frame 1 and the lower support frame 2 are all provided with multiple vertically aligned ventilation holes 11.

[0042] In this embodiment, the ventilation hole 11 facilitates ventilation and heat dissipation of the driver body 12.

[0043] As a technical optimization of this utility model, a thermally conductive silicone pad 17 is provided at the upper end of the upper support frame 1.

[0044] In this embodiment, the thermally conductive silicone pad 17 can assist in heat dissipation of the driver body 12.

[0045] As a technical optimization of this utility model, the polyurethane foam layer 3, the metal honeycomb panel 4 and the silicone damping pad 5 are bonded and fixed together by epoxy resin adhesive.

[0046] In this embodiment: the polyurethane foam layer 3, the metal honeycomb panel 4 and the silicone damping pad 5 are bonded and fixed together with epoxy resin adhesive to ensure a firm connection between the polyurethane foam layer 3, the metal honeycomb panel 4 and the silicone damping pad 5.

[0047] The working principle and usage process of this utility model are as follows: When in use, first rotate the threaded rods 14 on both sides. Rotating counterclockwise moves the L-shaped plate 15 toward the center, while rotating clockwise moves it in the opposite direction. The L-shaped plate 15 slides horizontally, so that the threaded positioning hole 16 on the inner wall of the L-shaped plate 15 corresponds to the mounting hole of the driver body 12. The driver body 12 is connected to the threaded positioning hole 16 of the L-shaped plate 15 by bolts passing through its mounting hole, thus completing the installation of the driver body 12.

[0048] The high-frequency mechanical vibration generated by the drive body 12 is quickly absorbed by the polyurethane foam layer 3 through material deformation. The honeycomb structure disperses the local impact force to the entire plane to prevent stress concentration. The metal honeycomb panel 4 is combined with the polyurethane foam layer 3 to suppress the resonance frequency. The low-frequency vibration transmitted from the outside of the equipment is dissipated by the viscoelasticity of the silicone damping pad 5, reducing the vibration transmission rate.

[0049] The shock-absorbing component is placed in the space formed by the upper support frame 1 and the lower support frame 2. The rectangular groove 10 of the vertical plate 6 is aligned with the slide groove 7 of the support frame. The screw 8 is rotated to push the locking block 9 to move horizontally along the slide groove 7. The locking block 9 is embedded in the rectangular groove 10 of the vertical plate 6 to achieve the lateral locking of the shock-absorbing component.

[0051] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
