Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a double-sided polishing device for disc-shaped parts. Background Technology

[0002] In the field of machining, disc-shaped parts are widely used, such as flywheels in automobile engines and gear discs in gearboxes. Their surface quality has a significant impact on the overall performance and service life of the equipment.

[0003] Traditional polishing methods for disc-shaped parts have many shortcomings. For disc-shaped parts of different sizes, the previous clamping devices are difficult to adjust flexibly, and special fixtures often need to be designed for specific sizes of parts. This not only increases production costs, but also consumes a lot of time in fixture replacement and debugging, which seriously affects production efficiency. Moreover, such single-size-fits-all fixtures cannot meet the diversified market demands of products. When it is necessary to process disc-shaped parts of different specifications, frequent fixture changes become a bottleneck in the production process.

[0004] In terms of polishing operations, traditional methods are mostly single-sided polishing. If both sides of a disc-shaped part are to be polished, one side must be processed first, and then the part must be re-clamped before polishing the other side. This process is not only cumbersome, but also prone to part positioning deviation due to multiple clamping, making it difficult to ensure the consistency of polishing accuracy on both sides. Furthermore, single-sided polishing can only process one side at a time, which is inefficient and cannot meet the needs of large-scale production.

[0005] Therefore, this utility model proposes a double-sided polishing device for disc-shaped parts to solve the above problems.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Each of the three internal threaded sleeves 2 has a screw 21 threaded inside it. The three mounting seats 3 are respectively fixedly mounted on the ends of the three screws 21 that are close to each other. The ends of the three screws 21 that are far apart from each other extend outside the support ring 1 and are rotatably mounted with connecting blocks 22. Connecting blocks 22 are fixedly mounted on the connecting blocks 22. A slide rod 23 is slidably mounted on the support ring 1, which can provide effective support for the mounting base 3. A double-sided geared disc 202 is rotatably mounted on the inner wall of the support ring 1. A motor 203 is fixedly mounted on the inner wall of the support ring 1. A drive gear 204 is fixedly sleeved on the output shaft of the motor 203. Driven gears 201 are fixedly sleeved on each of the three inner threaded sleeves 2. The drive gear 204 and the three driven gears 201 mesh with the double-sided geared disc 202. The distance between the three mounting bases 3 can be adjusted as needed, so as to adapt to the stable clamping of disc-shaped parts of different sizes.

[0031] Each of the three mounting seats 3 has a mounting groove on one side that is close to each other. Multiple guide rollers 31 arranged in parallel are rotatably mounted in the mounting groove. The outer surface of the guide rollers 31 should preferably be covered with a material with a certain degree of flexibility. This will prevent damage to the edge of the disc-shaped parts due to clamping and improve the stability of the clamping position. A second motor 32 is fixedly mounted on the bottom side of the mounting seat 3. The output shaft of the second motor 32 is axially fixedly connected to the spindle of one of the guide rollers 31. When the three mounting seats 3 move closer to each other, the disc-shaped parts can be clamped and lifted by the multiple guide rollers 31, and the rotation of the disc-shaped parts can be controlled at the same time.

[0032] The top of the strip box 4 has a strip-shaped opening, and the support frame 5 is slidably installed in the strip-shaped opening. An adjusting screw 41 is rotatably installed inside the strip box 4. A motor 3 42 is fixed to one side of the strip box 4. The output shaft of the motor 3 42 is axially fixedly connected to the adjusting screw 41, and the adjusting screw 41 is threadedly connected to the support frame 5. The lateral position of the support frame 5 can be adjusted as needed. Two mounting plates 6 are slidably installed on the support frame 5. Two polishing blocks 61 are fixedly installed on the sides of the two mounting plates 6 that are close to each other. Toothed plates 51 are fixedly installed on both mounting plates 6. A motor 4 52 is fixedly installed on the support frame 5. A transmission gear 53 is fixedly sleeved on the output shaft of the motor 4 52. Both toothed plates 51 mesh with the transmission gear 53. The distance between the two mounting plates 6 can be adjusted as needed, so that the device can better adapt to the polishing operation of disc-shaped parts of different thicknesses.

[0033] In this embodiment, in order to ensure the stability of the mounting plate 6 and the support frame 5 during position adjustment, guide rods are fixedly installed on the support frame 5 and inside the strip opening. There are two guide rods on the support frame 5, which are coaxially arranged, and the two mounting plates 6 and the support frame 5 are slidably connected to the corresponding guide rods.

[0034] In this embodiment, to prevent debris from entering the strip box 4 through the strip opening during the polishing process, a protective plate 7 is fixedly installed on the support frame 5. The protective plate 7 is L-shaped and slides in contact with the top side of the strip box 4.

[0035] In this embodiment, in order to ensure adjustment accuracy while avoiding uncontrolled displacement of the mounting base 3, support frame 5, mounting plate 6 and polishing block 61 due to equipment vibration during the polishing process, motor 1 203, motor 3 42 and motor 4 52 are all servo motors.

[0037] Working principle: In use, first connect the power supply, place the disc-shaped parts that need to be polished on both sides horizontally between the three mounting seats 3, and then the motor 203 controls the drive gear 204 to drive the double-sided gear disc 202 to rotate. This, in turn, drives the three internal threaded sleeves 2 to rotate through the three driven gears 201. With the cooperation of the screw 21, the three mounting seats 3 are controlled to move synchronously towards each other, so that the multiple guide rollers 31 can clamp and fix the disc-shaped parts and place the disc-shaped parts in the center position of the guide rollers 31. Then, start the motor 32. Three motors 32 control the rotation of a corresponding guide roller 31, thereby controlling the rotation of the disc-shaped parts. Then, motor 42 controls the rotation of the adjusting screw 41, thereby adjusting the lateral position of the support frame 5, mounting plate 6, and polishing block 61. After the polishing block 61 is adjusted to the desired polishing position, motor 52 controls the transmission gear 53 to drive the two toothed plates 51 to move. This controls the two mounting plates 6 to move the corresponding polishing blocks 61 closer to each other and into contact with the disc-shaped parts, thus achieving the polishing operation as the disc-shaped parts rotate.

[0038] The above provides a detailed description of a double-sided polishing device for disc-shaped parts provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
