Description

A precision grinding device for shaft machining Technical Field

[0001] This utility model belongs to the field of shaft machining technology, specifically a shaft machining precision grinding device. Background Technology

[0002] During the machining process of the shaft, it is necessary to perform fine grinding. Fine grinding is an important process between rough grinding and polishing. Its purpose is to ensure that the workpiece achieves the surface accuracy, dimensional accuracy and surface roughness required before polishing.

[0003] A Chinese patent with authorization announcement number CN220197102U discloses a precision grinding device for output shaft machining. Rotating the lifting screw, the lifting screw is threaded along the frame, which in turn drives the fixed seat at the bottom of the lifting screw to rise and fall. The vertical slider cooperates with the vertical slide rail to achieve stable lifting and falling. Turning on the motor drives the precision grinding head to rotate at high speed, which can perform precision grinding on the surface of the output shaft. This solution can adjust the height of the precision grinding head according to actual needs, avoiding the limitation of fixed precision grinding.

[0004] However, the above solution still has some problems. The temperature of the shaft increases during grinding, causing deformation at the grinding position. Furthermore, the debris generated by the grinding disc and the shaft cannot be cleaned in time, which leads to a reduction in grinding quality. Therefore, a shaft machining precision grinding device is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a shaft machining precision grinding device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a shaft machining precision grinding device, including: a machining table, an anti-drop plate fixedly connected to the inner wall of the machining table, a water tank fixedly connected to the bottom of the machining table, a discharge port opened on one side of the water tank, a filter screen fixedly connected inside the water tank, and the filter screen is sloping, a water pipe fixedly connected to the water tank, a water pump installed on the water pipe, the water pump installed on the upper surface of the machining table, the water pipe passing through the interior of the machining table, a support frame fixedly connected to the upper surface of the machining table, and first electric telescopic rods provided on both sides of the support frame, a first drive motor fixedly connected to one end of a set of first electric telescopic rods, the first drive motor being fixedly connected to one side of the support frame, and debris and water falling onto the filter screen after passing through the anti-drop plate, thereby separating the debris and water and reusing the water, and then cleaning the debris on the filter screen through the discharge port.

[0007] Preferably, the telescopic end of the first electric telescopic rod is fixedly connected to a connecting plate, the connecting plate is provided with a connecting groove, and two sets of limiting blocks are slidably connected inside the connecting groove. One side of each of the two sets of limiting blocks is fixedly connected to a fixing plate. The limiting blocks are located in the connecting groove, thereby cooperating with the hinge shaft to limit the range of motion of the two sets of fixing plates and avoid shaft shaking during the grinding process.

[0008] Preferably, an anti-slip pad is fixedly connected to one side of each of the two sets of fixing plates, a hinge shaft is installed on one side of the connecting plate, both sets of fixing plates are hinged to the hinge shaft, a spring is fixedly connected to one side of one set of fixing plates, and the shaft body is in contact with the anti-slip pad to increase the friction with the surface of the shaft body, thereby improving the fixing strength of the shaft body.

[0009] Preferably, one end of the spring is fixedly connected to one side of another set of fixing plates, and bolts are threadedly connected to the two sets of fixing plates. A second drive motor is fixedly connected to one side of the support frame. The fixing bolts are screwed into the two sets of fixing plates and cooperate with the hinge shaft to fix the fixing plates, thereby tightly fixing both ends of the shaft.

[0010] Preferably, the output end of the second drive motor is fixedly connected to a bidirectional threaded rod, both ends of which are rotatably connected to the inside of the support frame. An adjusting block is threadedly connected to the bidirectional threaded rod, and the adjusting block is connected to one end of the water pipe. When the second drive motor is started, the bidirectional threaded rod is driven to rotate. Since the threads on the bidirectional threaded rod match the threads inside the adjusting block, the position of the adjusting block can be adjusted.

[0011] Preferably, a second electric telescopic rod is fixedly connected to the lower surface of the adjusting block, a third drive motor is fixedly connected to the telescopic end of the second electric telescopic rod, and a grinding disc is fixedly connected to the output end of the third drive motor. By operating the second electric telescopic rod, the height of the grinding disc can be adjusted, thereby adjusting the grinding depth of the shaft.

[0012] The advantages of this utility model are: while grinding, the water pump is started, and water is drawn out of the water tank through the water pipe. The grinding area is rinsed while the shaft is being ground, thereby reducing the temperature of the shaft during grinding and preventing deformation due to excessive temperature. At the same time, the debris generated between the grinding disc and the shaft is washed off, thus preventing the debris from affecting the grinding. In this way, the two work together to improve the grinding quality of the shaft.

[0013] This invention involves rotating two sets of fixing plates around a hinge axis to both sides, stretching the spring and increasing the gap between the two sets of fixing plates. The two ends of the shaft are then placed into the two sets of fixing plates. Loosening the fixing plates allows the two sets of fixing plates to rotate around the hinge axis under the force of the spring. Bolts are then screwed into the two sets of fixing plates to fix the two ends of the shaft. After unscrewing the bolts, the two sets of fixing plates are rotated outwards to remove the shaft from the device, thus improving the ease of shaft installation and removal.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please refer to Figures 1-5. A shaft machining and precision grinding device includes: a machining table 1, an anti-drop plate 2 fixedly connected to the inner wall of the machining table 1, a water tank 3 fixedly connected to the bottom of the machining table 1, a discharge port 4 opened on one side of the water tank 3, a filter screen 5 fixedly connected inside the water tank 3, and the filter screen 5 is sloped, a water pipe 6 fixedly connected to the water tank 3, a water pump 7 installed on the water pipe 6, the water pump 7 installed on the upper surface of the machining table 1, the water pipe 6 passing through the interior of the machining table 1, a support frame 8 fixedly connected to the upper surface of the machining table 1, first electric telescopic rods 9 provided on both sides of the support frame 8, a first drive motor 10 fixedly connected to one end of a set of first electric telescopic rods 9, and the first drive motor 10 fixedly connected to... On one side of the support frame 8, a connecting plate 11 is fixedly connected to the telescopic end of the first electric telescopic rod 9. A connecting groove 12 is provided on the connecting plate 11. Two sets of limiting blocks 13 are slidably connected inside the connecting groove 12. A fixing plate 15 is fixedly connected to one side of each of the two sets of limiting blocks 13. An anti-slip pad 16 is fixedly connected to one side of each of the two sets of fixing plates 15. A hinge shaft 14 is installed on one side of the connecting plate 11. Both sets of fixing plates 15 are hinged to the hinge shaft 14. A spring 17 is fixedly connected to one side of one set of fixing plates 15. One end of the spring 17 is fixedly connected to one side of the other set of fixing plates 15. Bolts 18 are threadedly connected to both sets of fixing plates 15. A second drive motor 19 is fixedly connected to one side of the support frame 8.

[0023] During the shaft machining process, fine grinding is required. Fine grinding is an important step between rough grinding and polishing. Therefore, a fine grinding device for shaft machining is proposed. In actual use, the third drive motor 22 drives the grinding disc 23 to rotate, which can grind the shaft. At the same time, the water pump 7 is started, and water is pumped out of the water tank 3 through the water pipe 6. The grinding area is rinsed with water while the shaft is being ground, thereby reducing the temperature of the shaft during grinding and preventing deformation due to excessive temperature. At the same time, the debris generated between the grinding disc 23 and the shaft is washed off, thus preventing the debris from affecting the grinding. The combination of these two methods improves the grinding quality of the shaft. After passing through the anti-drop plate 2, the debris and water fall onto the filter screen 5, which can separate the debris and water, allowing the water to be reused.

[0024] Unscrew bolt 18, then rotate the two sets of fixing plates 15 to both sides around the hinge shaft 14, causing the limiting block 13 to move along the connecting groove 12. At the same time, stretch spring 17, increasing the gap between the two sets of fixing plates 15. Place both ends of the shaft into the two sets of fixing plates 15, then release the pull on the fixing plates 15. Under the force of spring 17, the two sets of fixing plates 15 rotate around the hinge shaft 14, causing the shaft to come into contact with the anti-slip pad 16, increasing the friction with the shaft surface. Then screw bolt 18 into the two sets of fixing plates 15. Within plate 15, both ends of the shaft can be fixed. After unscrewing bolts 18, the two sets of fixing plates 15 can be rotated outward to remove the shaft from the device, thus improving the convenience of shaft installation and removal. When grinding the shaft, the first drive motor 10 is started, which drives the first electric telescopic rod 9 to rotate, thereby rotating the shaft and making the grinding of the shaft more thorough. By operating the two sets of first electric telescopic rods 9, the distance between the fixing plates 15 on both sides can be adjusted, thereby fixing shafts of different lengths and expanding the applicability of the device.

[0025] Please refer to Figures 1-5. The output end of the second drive motor 19 is fixedly connected to a bidirectional threaded rod 24. Both ends of the bidirectional threaded rod 24 are rotatably connected to the inside of the support frame 8. An adjusting block 20 is threadedly connected to the bidirectional threaded rod 24. The adjusting block 20 is connected to one end of the water pipe 6. The lower surface of the adjusting block 20 is fixedly connected to a second electric telescopic rod 21. The telescopic end of the second electric telescopic rod 21 is fixedly connected to a third drive motor 22. The output end of the third drive motor 22 is fixedly connected to a grinding disc 23.

[0026] After fixing the shaft, start the second drive motor 19 to drive the bidirectional threaded rod 24 to rotate. Since the thread on the bidirectional threaded rod 24 matches the thread inside the adjusting block 20, the position of the adjusting block 20 can be adjusted, causing the grinding disc 23 and the water pipe 6 to move synchronously. Then start the third drive motor 22 to drive the grinding disc 23 to rotate. By operating the second electric telescopic rod 21, the height of the grinding disc 23 can be adjusted, thereby adjusting the grinding depth of the shaft. In addition, the grinding area can be sprayed while grinding to avoid the debris generated by grinding affecting the grinding position.

[0027] Working principle: The two sets of fixing plates 15 are rotated to both sides around the hinge shaft 14, causing the limiting block 13 to move along the connecting groove 12. At the same time, the spring 17 is stretched, increasing the gap between the two sets of fixing plates 15. The two ends of the shaft are then placed into the two sets of fixing plates 15. After releasing the tension on the fixing plates 15, the two sets of fixing plates 15 rotate around the hinge shaft 14 under the elastic force of the spring 17, causing the shaft to come into contact with the anti-slip pad 16. The bolts 18 are then screwed into the two sets of fixing plates 15 to fix the two ends of the shaft. The second drive motor 19 is then started, driving the bidirectional threaded rod 24 to rotate. The position of the adjusting block 20 is adjusted, which drives the grinding disc 23 and the water pipe 6 to move synchronously. Then, the third drive motor 22 is started, which drives the grinding disc 23 to rotate. The height of the grinding disc 23 can be adjusted by the operation of the second electric telescopic rod 21, thereby adjusting the grinding depth of the shaft. At the same time, the water pump 7 is started, and water is pumped out of the water tank 3 through the water pipe 6. The grinding area is flushed while the shaft is being ground, thereby reducing the temperature of the shaft during grinding and preventing deformation of the shaft due to excessive temperature. At the same time, the debris generated between the grinding disc 23 and the shaft is washed off, thereby preventing the debris from affecting the grinding.
