Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and more specifically, to a cutting mechanism for processing bearings based on low noise vibration. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Machining bearings often requires a cutting step, which necessitates the use of appropriate cutting equipment. However, existing technologies have the following shortcomings in their application:

[0003] The machining of bearings often generates significant noise, which may damage the operator's hearing and affect their health over time. In addition, the cutting motor usually vibrates to some extent during operation, which can affect the service life and stability of the cutting motor.

[0004] Therefore, there is an urgent need for a cutting mechanism for machining bearings with low noise and vibration to solve the above problems. Utility Model Content

In addition, the cutting motor usually generates a certain degree of vibration during operation, which affects the service life and stability of the cutting motor.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cutting mechanism for machining low-noise vibration bearings is proposed to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] A cutting mechanism for machining low-noise vibration bearings includes a base, a soundproof cover mounted on the top of the base, a top cover mounted on the soundproof cover, a connecting frame and a support plate fixedly connected to the top of the base, a cutting motor mounted on the front of the support plate, a cutting blade fixedly connected to the output end of the cutting motor, an electric push rod fixedly connected to the connecting frame, a connecting plate fixedly connected to the push rod end of the electric push rod, four first connecting blocks arranged in a circle fixedly connected to the back of the connecting plate, four through slots arranged in a circle on the connecting frame, and a second connecting block slidably connected to each of the four through slots, a connecting plate hinged between the first connecting blocks and the second connecting blocks, an arc-shaped clamping plate fixedly connected to the back of the second connecting blocks, a rubber buffer pad mounted on the arc-shaped clamping plate, and the cutting motor located between the four rubber buffer pads.

[0010] As a preferred technical solution of this application, an electric slide is fixedly installed on the top of the base, and two slide seats are provided on the electric slide. A fixing plate is fixedly connected to the top of the two slide seats, and a three-jaw pneumatic chuck is installed on the front of the fixing plate.

[0031] Example:

[0032] like Figure 1-4As shown, this embodiment proposes a cutting mechanism for low-noise vibration bearing processing, including a base 1, a soundproof cover 2 mounted on the top of the base 1, a top cover 3 mounted on the soundproof cover 2, a connecting frame 4 and a support plate 5 fixedly connected to the top of the base 1, a cutting motor 6 mounted on the front of the support plate 5, a blade 7 fixedly connected to the output end of the cutting motor 6, an electric push rod 8 fixedly connected to the connecting frame 4, the electric push rod 8 is activated, and a connecting plate 9 is fixedly connected to the push rod end of the electric push rod 8, driving the connecting plate 9 to move away from the support plate 5. Four first connecting blocks 10 arranged in a circle are fixedly connected to the back of the connecting plate 9, and the four first connecting blocks 10 move synchronously with the connecting plate 9. Four through slots 11 arranged in a circle are opened on the connecting frame 4, and second connecting blocks 12 are slidably connected in each of the four through slots 11. The first connecting blocks 10 and the second connecting blocks 12 are connected to each other. Four connecting plates 13 are hinged together. Through the four connecting plates 13, four second connecting blocks 12 slide in the four through slots 11 respectively, so that the four second connecting blocks 12 move closer to each other. Arc-shaped clamping plates 14 are fixedly connected to the back of the second connecting blocks 12. The four arc-shaped clamping plates 14 move with the four second connecting blocks 12 respectively. Rubber buffer pads 15 are installed on the arc-shaped clamping plates 14. The cutting motor 6 is located between the four rubber buffer pads 15, so that the four rubber buffer pads 15 are in contact with the outer surface of the cutting motor 6. When the cutting motor 6 runs, it drives the blade 7 to rotate at high speed. The contact between the rubber buffer pads 15 and the outer surface of the cutting motor 6 will generate a large friction force, which can effectively hinder the vibration transmission of the cutting motor 6, so that the vibration is continuously weakened during the transmission process, reducing the propagation of vibration between different components, ensuring the stability of the cutting motor 6 during operation, and improving its service life.

[0033] like Figure 1 and Figure 3 As shown, an electric slide table 16 is fixedly installed on the top of the base 1. Two slide blocks 17 are provided on the electric slide table 16. A fixed plate 18 is fixedly connected to the top of the two slide blocks 17. A three-jaw pneumatic chuck 19 is installed on the front of the fixed plate 18. The operator opens the top cover 3 by the handle, places the bearing to be processed on the three-jaw pneumatic chuck 19, fixes the bearing by the three-jaw pneumatic chuck 19, closes the top cover 3, and starts the electric slide table 16. The electric slide table 16 drives the two slide blocks 17 and the fixed plate 18 to move horizontally to the right. The three-jaw pneumatic chuck 19 and the bearing follow the fixed plate 18. During this process, the bearing will come into contact with the high-speed rotating blade 7, thereby cutting the bearing.

[0034] like Figure 1 As shown, a sound-absorbing plate 20 is installed at the bottom of the top cover 3. The sound-absorbing plate 20 can effectively absorb the noise generated by the bearing during the processing.

[0035] like Figure 1 As shown, the fixing plate 18 is parallel to the support plate 5.

[0036] like Figure 1 As shown, the soundproof cover 2 uses double-layer soundproofing material. The inner layer of the soundproof cover 2 is sound-absorbing cotton, and the outer layer is a sound-insulating metal plate. This structure can effectively absorb and block the noise generated during the cutting process. Together with the sound-absorbing plate 20 at the bottom of the top cover 3, it can effectively prevent noise from spreading to the surrounding environment, avoid damage to the hearing of the operators, and achieve a good noise reduction effect.

[0037] like Figure 1 As shown, the top cover 3 is embedded with transparent glass 21, which allows for easy observation of the bearing's processing status during the cutting process.

[0038] like Figure 2 and Figure 3 As shown, two guide rods 22 are fixedly connected to the front of the connecting plate 9. The two guide rods 22 are symmetrically distributed about the central axis of the electric push rod 8. The end of the guide rod 22 away from the connecting plate 9 passes through the connecting frame 4. The two guide rods 22 can guide the connecting plate 9 when it moves, ensuring the stability of the connecting plate 9 when it moves.

[0039] Specifically, in use, the cutting mechanism for low-noise vibration bearing processing is as follows: the cutting motor 6, electric push rod 8, and electric slide table 16 are all electrically connected to an external control power supply. The operator opens the top cover 3 using the handle, places the bearing to be processed on the three-jaw pneumatic chuck 19, and fixes the bearing using the three-jaw pneumatic chuck 19. Then, the top cover 3 is closed, and the cutting motor 6, electric push rod 8, and electric slide table 16 are started. The electric push rod 8 drives the connecting plate 9 to move away from the support plate 5. The four first connecting blocks 10 move synchronously with the connecting plate 9. Through the four connecting plates 13, the four second connecting blocks 12 slide in the four through slots 11 respectively, so that the four second connecting blocks 12 move closer to each other. The four arc-shaped clamping plates 14 move with the four second connecting blocks 12 respectively, and finally, the four rubber buffer pads 15 are in contact with the outer surface of the cutting motor 6. When the cutting motor 6 runs, it drives the blade 7 to rotate at high speed, and the rubber buffer pads 15 and the cutting motor 6 are in contact with each other. The contact between the outer surfaces of the machine 6 and the cutting motor 6 generates significant friction, which effectively hinders the transmission of vibration. This weakens the vibration during transmission, reduces its propagation between different components, and ensures the stability of the cutting motor 6 during operation. When the electric slide 16 is running, it drives the two slides 17 and the fixed plate 18 to move horizontally to the right. The three-jaw pneumatic chuck 19 and the bearing follow the fixed plate 18. During this process, the bearing comes into contact with the high-speed rotating blade 7, thus cutting the bearing. The soundproof cover 2 uses double-layer soundproofing material, with sound-absorbing cotton as the inner layer and sound-absorbing metal plate as the outer layer. This structure effectively absorbs and blocks the noise generated during the cutting process. Combined with the sound-absorbing plate 20 at the bottom of the top cover 3, it effectively prevents noise from spreading to the surrounding environment, avoiding damage to the operator's hearing and achieving a good noise reduction effect. After the bearing is processed, the operator can open the top cover 3 with the handle and remove the bearing from the three-jaw pneumatic chuck 19.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
