Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a grinding machine for bearing processing. Background Technology

[0002] Bearings keep rotating parts such as shafts, gears, and impellers in a fixed position and allow them to rotate stably around their own axis. Grinding machines can precisely grind these parts to within specified tolerances.

[0003] In existing technologies, it is difficult to fix bearings of different diameters. As a result, the bearings may shift or wobble during the grinding process, leading to deviations between the machined dimensions and the design dimensions. This, in turn, increases auxiliary processing time and reduces production efficiency.

[0004] In response to the technical problem of difficulty in fixing bearings of different diameters, this application proposes a grinding machine for bearing processing. Utility Model Content

This invention proposes a bearing grinding machine that, through a motor and hydraulic rods, adjusts the positions of four movable rods and the grinding rollers on both sides to accommodate bearings of different diameters and thicknesses. This ensures that the four movable rods can accurately fix bearings of different diameters, maintaining stability during grinding, guaranteeing uniformity and accuracy, thereby improving the processing precision and efficiency of bearings.

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

[0029] For details, please refer to Figure 1A controller is installed at the front end of the processing table 1. The controller is electrically connected to motor 3, hydraulic rod 8, motor 10 and exhaust fan 22. The controller adjusts the position of the four movable rods 7 and the position of the two grinding rollers 16 by motor 3 and hydraulic rod 8 to accommodate bearings of different diameters and thicknesses. This ensures that the four movable rods 7 can accurately fix bearings of different diameters, keep them stable during grinding, and ensure the uniformity and accuracy of grinding, thereby improving the processing precision of the bearings and increasing processing efficiency.

[0030] Reference Figures 5-7 As shown, each hydraulic rod 8 is fixedly connected to a connecting seat 9 at one inward end. Both sides of the inner wall of the connecting seat 9 are rotatably connected to mounting cylinders 11. A grinding roller 16 is installed on the inner wall of the mounting cylinder 11. Both ends of the grinding roller 16 are fixedly connected to connecting cylinders 13. Springs 14 are fixedly connected to both sides of the inner wall of the connecting cylinder 13. A locking block 15 is fixedly connected to the other end of each spring 14. The outer walls of the locking blocks 15 are slidably connected to both sides of the inner wall of the connecting cylinder 13. Grooves 12 are formed on both sides of the inner wall of the mounting cylinder 11, and the outer walls of the locking blocks 15 are all located within the grooves 12. The shape of the card block 15 fits the card slot 12. Push rods 17 are slidably connected to both sides of the inner wall of the connecting seat 9. Movable blocks 19 are fixedly connected to one end of each push rod 17. Springs 18 are fixedly connected to the outer wall of each push rod 17. The other end of each spring 18 is fixedly connected to both ends of the connecting seat 9 for the disassembly and assembly of the grinding roller 16. A collection box 20 is provided on the inner wall of the processing table 1. A filter screen 21 is fixedly connected to the inner wall of the collection box 20. A fan 22 is fixedly connected to the right end of the processing table 1. A channel is opened on the inner wall of the processing table 1 for the collection of debris.

[0031] Specifically, after disassembly, the movable blocks 19 on both sides are pushed back to their original positions by spring 18. During installation, the locking blocks 15 on both sides are pressed to retract into the connecting cylinder 13, and the connecting cylinders 13 on both sides are inserted into the mounting cylinder 11. After installation, the locking blocks 15 are locked into the slots 12 by spring 14 to complete the installation. The detachable design facilitates the replacement of the grinding roller 16 and collects the debris generated during grinding. It allows for quick disassembly and replacement of the new grinding roller 16, reducing equipment downtime, enabling production to resume as soon as possible, improving overall production efficiency, and helping to keep the processing area clean and reduce pollution to the production environment.

[0032] Working principle: First, the bearing is placed on the movable rod 7, and the controller starts motor 3. Motor 3 drives the rotating plate 4 to rotate, and at the same time drives the four sliding rods 6 on the four sides to slide on the inner wall of the slide groove 5. It also drives the four sliding rods 6 and the movable rod 7 to move outward synchronously, supporting and fixing the inner wall of the bearing. After fixing, the hydraulic rods 8 on both sides are started. The hydraulic rods 8 drive the connecting seats 9 on both sides to move to the middle side, so that the grinding roller 16 contacts the outer wall of the bearing. Then, motor 10 is started. Motor 10 drives the mounting cylinder 11 and the grinding roller 16 to rotate, grinding the outer surface of the bearing. At the same time as grinding, the pump can be started. The blower 22 and the exhaust fan 22 generate negative pressure inside the channel to suck up the grinding debris and collect it in the collection box 20 through the filter screen 21. After grinding is completed, the collection box 20 is pulled out for processing. Next, when it is necessary to replace the grinding roller 16, first rotate the grinding roller 16, align the movable blocks 19 on both sides with the locking blocks 15, and then press down the push rod 17. The push rod 17 drives the movable blocks 19 to move to the middle side, remove the locking blocks 15 on both sides from the locking slots 12, and then push the grinding roller 16 to the middle side to remove the connecting cylinder 13 from the mounting cylinder 11, thus completing the disassembly.
