Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to an inner ring machining device for bearing manufacturing. Background Technology

[0002] Bearings are an important component in mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Bearings are widely used in various mechanical equipment, such as automobiles, airplanes, and industrial equipment. They are one of the key components to ensure the normal operation of mechanical equipment. At the same time, in the production of bearings, the inner ring surface of newly produced bearings will have burrs, so a filing device is needed to cut and remove the excess burrs from the inner ring.

[0003] The size of the round file on existing filing devices is mostly fixed. The fixed round file means that the filing device can only process bearing inner rings with a specific inner diameter. When it is necessary to remove burrs from bearing inner rings with different inner diameters, the existing filing devices are often unable to adapt, making it impossible for the round file to fit the bearing inner ring, resulting in poor cutting effect. Utility Model Content

[0004] The purpose of this invention is to provide an inner ring machining device for bearing manufacturing, in order to solve the problem that most round files are fixed in size and can only be used to cut bearing inner rings with a specific inner diameter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bearing manufacturing inner ring machining apparatus includes a frame on which a cutting mechanism capable of filing the bearing inner ring is mounted.

[0008] As a further description of the above technical solution:

[0009] The rotating assembly includes a second gear rotatably mounted on the bottom of the lifting plate. A connecting rod is fixedly installed inside the second gear. A first cylinder is fixedly installed at the bottom end of the connecting rod. A second cylinder and a round file are provided on one side of the first cylinder. An extension component capable of adjusting the position of the round file is also mounted on the first cylinder.

[0010] As a further description of the above technical solution:

[0011] The extension component includes a first screw threaded inside the plug rod, a plurality of first rotating plates hinged to the outer wall of the first cylinder, a connecting plate hinged to one end of the first rotating plate, a slide fixedly installed on one side of the connecting plate, a slider slidably connected inside the slide, and a second rotating plate hinged between the slider and the second cylinder.

[0012] As a further description of the above technical solution:

[0013] The first rotating plate and the second rotating plate are connected at their centers by a rotating shaft. The round file is inserted into the connecting plate. The second cylinder is rotatably mounted on the first screw. The lifting plate is fixedly mounted on the output end of the electric telescopic rod. The first gear and the second gear mesh.

[0014] As a further description of the above technical solution:

[0015] The fixing assembly includes a collection box placed on a frame, a support frame fixedly installed on the frame, a protective ring fixedly installed at the top of the support frame, and second screws threaded to both ends of the protective ring, with a clamping plate fixedly installed at one end of the second screw.

[0016] As a further description of the above technical solution:

[0017] The collection box is located directly below the protective ring, and the bottom end of the protective ring has several through slots, with the clamp plate in contact with the top of the through slots.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 - Figure 5 As shown, the present invention provides an inner ring machining device for bearing manufacturing, including a frame 10, on which a cutting mechanism 20 capable of filing the inner ring of the bearing is mounted;

[0030] The cutting mechanism 20 includes a lifting plate 21 slidably mounted on the frame 10. The lifting plate 21 acts as a limiter through the frame 10 when it is raised or lowered. An electric telescopic rod 22 is fixedly mounted on the top of the frame 10. A servo motor 23 is fixedly mounted on the lifting plate 21. A first gear 24 is fixedly mounted on the output end of the servo motor 23. The servo motor 23 can drive the first gear 24 to rotate. A rotating component 25 capable of rotating and filing the inner ring of the bearing is mounted on the lifting plate 21. A fixing component 26 capable of fixing the bearing is also mounted on the frame 10.

[0031] like Figure 2As shown, the rotating assembly 25 includes a second gear 251 rotatably mounted on the bottom of the lifting plate 21. A plug rod 252 is fixedly mounted inside the second gear 251. When the second gear 251 rotates, it will also drive the plug rod 252 to rotate. A first cylinder 253 is fixedly mounted on the bottom end of the plug rod 252. A second cylinder 254 and a round file 255 are provided on one side of the first cylinder 253. The round file 255 is distributed in a ring around the first cylinder 253 and the second cylinder 254. The inner ring of the bearing can be filed by the round file 255. An extension component 256 that can adjust the position of the round file 255 is also mounted on the first cylinder 253.

[0032] After the bearing is fixed, the electric telescopic rod 22 is activated to drive the lifting plate 21 to descend, so that the round file 255 is located in the inner ring of the bearing. Then, the servo motor 23 is activated to drive the first gear 24 to rotate. Through meshing, the second gear 251 will also rotate synchronously. The rotating second gear 251 will also cause the plug rod 252 to drive the first cylinder 253 and the second cylinder 254 to start rotating, so that several round files 255 can rotate in the inner ring of the bearing. At the same time, the round files 255 can file and remove burrs from the inner ring of the bearing.

[0033] like Figure 3 - Figure 4 As shown, the extension component 256 includes a first screw 2561 threadedly installed inside the plug rod 252. A plurality of first rotating plates 2562 are hinged to the outer wall of the first cylinder 253. A connecting plate 2563 is hinged to one end of the first rotating plate 2562. A slide 2564 is fixedly installed on one side of the connecting plate 2563. A slider 2565 is slidably connected inside the slide 2564. The slider 2565 can move through the slide 2564. A second rotating plate 2566 is hinged between the slider 2565 and the second cylinder 254. The second rotating plate 2566 and the first rotating plate 2562 are arranged crosswise.

[0034] In more detail, the center of the first rotating plate 2562 and the second rotating plate 2566 are connected by a rotating shaft. The round file 255 is inserted into the connecting plate 2563. When the round file 255 is worn, it can be removed from the connecting plate 2563 simply by pulling the round file 255 upward. The second cylinder 254 is rotatably mounted on the first screw 2561. The lifting plate 21 is fixedly mounted on the output end of the electric telescopic rod 22. The first gear 24 meshes with the second gear 251.

[0035] When facing a bearing with a different inner diameter, after several round files 255 descend to the inner ring of the bearing, the second cylinder 254 can be moved by rotating the first screw 2561. As the second cylinder 254 moves, one end of the second rotating plate 2566 will also move. The other end of the second rotating plate 2566 will move within the slide 2564 via the slider 2565. At the same time, the second rotating plate 2566 and the first rotating plate 2562 are cross-spread by the pivot at the center of the second rotating plate 2566 and the first rotating plate 2562, thereby pushing the connecting plate 2563 outward. This allows the round files 255 to be adjusted in position to fit the inner ring of bearings with different inner diameters.

[0036] like Figure 5 As shown, the fixing component 26 includes a collection box 261 placed on the frame 10 to collect the debris generated during filing. A support frame 262 is fixedly installed on the frame 10. A protective ring 263 is fixedly installed on the top of the support frame 262 to prevent debris from flying around. The two ends of the protective ring 263 are threadedly connected to a second screw 264. A clamping plate 265 is fixedly installed on one end of the second screw 264.

[0037] In use, the bearing is placed inside the protective ring 263, and then the second screws 264 on both sides are rotated so that the clamping plate 265 can clamp the two ends of the bearing. The debris generated during filing will enter the collection box 261 through the through groove at the bottom of the protective ring 263 and be collected.

[0038] In more detail, the collection box 261 is located directly below the protective ring 263. The bottom end of the protective ring 263 has several through slots, and the clamping plate 265 contacts the top of the through slots, thereby limiting the clamping plate 265.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
