Description

Technical Field

[0001] The utility model relates to a motor bracket, in particular to a motor bracket with shock absorption and noise reduction functions. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy, and its working principle is based on the law of electromagnetic induction. When a current-carrying coil is placed in a magnetic field, an electromagnetic force will be generated, causing the coil to rotate, thereby driving the rotor to rotate and output mechanical work. Motors are widely used. During the processing of mechanical equipment, various mechanical processing equipment is usually required, such as CNC lathes, CNC milling machines, CNC boring machines, etc., and these processing equipment all require the use of motors. However, during the operation of the motor, due to principles such as mechanical imbalance, electromagnetic force imbalance, or resonance, the motor will vibrate, resulting in vibration noise. Moreover, eddy current noise will also be generated during the rotation of the motor rotor. Therefore, certain shock absorption and noise reduction treatments are required during the operation of the motor. Currently, for the shock absorption and noise reduction of motors, shock pads are usually added to the bottom of the motor base or a motor cover is added outside the motor to reduce shock and noise. However, this method has a simple structure, a relatively single form of shock absorption and noise reduction, a small coverage area for the motor, and fixed positions, and it cannot perform targeted processing according to the actual vibration position of the motor, resulting in an unsatisfactory shock absorption and noise reduction effect. Content of the Utility Model

[0003] The purpose of the utility model is to provide a motor bracket with shock absorption and noise reduction functions. The utility model has the characteristics of targeted adjustment of the shock absorption position and improvement of the shock absorption and noise reduction effect.

A shock absorption layer is provided between the base and the motor. A protective cover that surrounds the outside of the motor and has one end open is provided on the base. Sound-absorbing cotton is provided on the inner side wall of the protective cover. A plurality of guide rods are provided inside the protective cover. A shock absorption block is slidably connected to the guide rods. One side of the shock absorption block abuts against the protective cover, and the other side of the shock absorption block abuts against the motor.

[0005] In the aforementioned motor bracket with shock absorption and noise reduction functions, both ends of the guide rod pass through the sound-absorbing cotton and are connected to the protective cover. A pressing nut for fixing the sound-absorbing cotton and a fixing nut for fixing the shock absorption block are threadedly connected to the guide rod.

[0006] In the aforementioned motor bracket with shock absorption and noise reduction functions, at least two guide rods are provided, and the two guide rods are respectively distributed on the side and top of the motor.

[0007] In the aforementioned motor bracket with shock absorption and noise reduction functions, a sliding groove is provided on the surface of the base. A sliding block that is slidably connected to the sliding groove is provided at the bottom of the protective cover. A fixing component for connecting to the base is provided on the sliding block.

[0008] In the aforementioned motor mount for shock absorption and noise reduction, the fixing component uses a positioning pin or a fixing bolt.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The present utility model sets a base at the bottom of the motor and a protective cover outside the motor, thereby protecting the motor, reducing the interference and pollution of external forces and pollutants to the motor, and the protective cover isolates the working noise of the motor, and the sound-absorbing cotton arranged in the protective cover absorbs the working noise of the motor, thereby greatly reducing the influence of the working noise of the motor on the external environment;

[0019] Embodiment:

[0020] As Figure 1 - Figure 2 shown, a motor mount for shock absorption and noise reduction includes a base 2 installed at the bottom of a motor 1. A shock-absorbing layer 21 is provided between the base 2 and the motor 1. A protective cover 3 that surrounds the outside of the motor 1 and has an open end is provided on the base 2. Sound-absorbing cotton 31 is provided on the inner side wall of the protective cover 3. A plurality of guide rods 32 are provided inside the protective cover 3. A shock-absorbing block 33 is slidably connected to the guide rods 32. One side of the shock-absorbing block 33 abuts against the protective cover 3, and the other side of the shock-absorbing block 33 abuts against the motor 1.

[0021] The base 2 is provided at the bottom of the motor 1, and the protective cover 3 is provided outside the motor 1, thereby protecting the motor 1 and reducing the interference, pollution, etc. of external forces and pollutants on the motor 1. Moreover, the protective cover 3 isolates the working noise of the motor 1, and the sound-absorbing cotton 31 provided inside the protective cover 3 absorbs the working noise of the motor 1, thereby greatly reducing the influence of the working noise of the motor 1 on the external environment;

[0022] In addition, a shock-absorbing layer 21 is provided on the base 2, a plurality of guide rods 32 are provided around the motor 1, and a shock-absorbing block 33 is movably connected to the guide rods 32, thereby absorbing and buffering the vibration of the motor 1 in different directions and improving the stability and quietness of the operation of the motor 1. Further, the shock-absorbing block 33 can move back and forth on the guide rods 32, and the position of the shock-absorbing block 33 can be adjusted according to the shape and vibration position of the motor 1, so that the shock-absorbing block 33 closely adheres to the vibration surface of the motor 1 for targeted shock absorption, and the shock-absorbing effect is better.

[0023] Both ends of the guide rod 32 pass through the sound-absorbing cotton 31 and are connected to the protective cover 3. A compression nut 34 for fixing the sound-absorbing cotton 31 and a fixing nut 35 for fixing the shock-absorbing block 33 are threadedly connected to the guide rod 32. The sound-absorbing cotton 31 is fixed by the compression nut 34, and the shock-absorbing block 33 is fixed by the fixing nuts 35 provided on both sides of the shock-absorbing block 33, thereby improving the installation structural stability of the sound-absorbing cotton 31 and the shock-absorbing block 33 and ensuring their working effects; preventing the positions of the sound-absorbing cotton 31 and the shock-absorbing block 33 from being shaken by the vibration of the motor and affecting the shock-absorbing and sound-absorbing effects of the sound-absorbing cotton 31 and the shock-absorbing block 33.

[0024] At least two guide rods 32 are provided, and the two guide rods 32 are respectively distributed on the side and top of the motor 1. By providing multiple guide rods 32 distributed in different orientations, the noise and vibration of the motor 1 can be processed in all directions, and the processing is more comprehensive.

[0025] A sliding groove is provided on the surface of the base 2, and a slider 22 slidably connected to the sliding groove is provided at the bottom of the protective cover 3. A fixing component connected to the base 2 is provided on the slider 22. The fixing component uses a positioning pin or a fixing bolt 23. The protective cover 3 is slidably connected to the base 2, which facilitates moving the protective cover 3 to expose the motor 1 for maintenance of the motor 1. After adjusting the position of the protective cover 3, the protective cover 3 is fixed to the base 2 by a positioning pin or a fixing bolt 23, improving the stability of the installation work of the protective cover 3 and preventing it from moving easily and affecting the protection effect on the motor 1.

[0026] A heat dissipation through hole is provided on one side of the protective cover 3, and a heat dissipation fan 36 and a filter net 37 are provided in the heat dissipation through hole. By providing a separate fan on the protective cover 3 to dissipate heat from the motor 1 stably and continuously, the heat dissipation effect is good. When it is necessary to replace the motor 1 or the heat dissipation fan 36, the protective cover 3 is moved along the base 2 by the cooperation of the slider 22 and the sliding groove, separating the heat dissipation fan 36 from the motor 1. Removal, installation, and replacement are all relatively convenient, saving maintenance costs.
