Description

Technical Field

[0001] The utility model belongs to the technical field of bearing rings, in particular to a grinding device for machining outer spherical bearing rings. Background Art

[0002] The bearing ring is an important component of the rolling bearing, usually composed of an inner ring and an outer ring. The bearing sleeve is an annular part of a radial rolling bearing with one or more raceways. The inner ring is usually fixed on the journal and rotates with the shaft, while the outer ring is fixed on the bearing seat or the housing of the machine. There are grooves on the surface of the inner and outer rings for the rolling elements to roll, and these grooves are called raceways.

[0003] Bearing rings are not only used to fix bearings, but also play an important role in improving the service life of bearings. Therefore, when processing bearing rings, their surfaces need to be polished and ground. Since the specifications of bearing rings vary greatly, existing grinding equipment often needs to manually tighten bolts according to different sizes to limit the position of bearing rings. Although the bearing rings can be fixed, it is time-consuming and labor-intensive, and the fixing efficiency is low, which greatly limits the scope of application of the grinding equipment.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-6 As shown, the utility model is a grinding device for processing an outer spherical bearing ring, comprising a base body 1 and a support frame 2 fixed to one side of the upper end of the base body 1, and also comprising:

[0029] The adjusting cylinder 3 is arranged inside the supporting frame 2. An adjusting mechanism is arranged on one side of the supporting frame 2 for adjusting the angle of the adjusting cylinder 3. The adjusting mechanism includes a gear body 4 and a driving assembly 5. The gear body 4 is evenly fixed on the outer surface of the adjusting cylinder 3. The driving assembly 5 is arranged on the outer side of the supporting frame 2. A driving gear is arranged at the output end of the driving assembly 5 and meshes with the gear body 4. The position of the adjusting cylinder 3 can be limited by arranging the supporting frame 2. If the adjusting cylinder 3 needs to be rotated and adjusted, the driving assembly 5 can be turned on. The arranged driving assembly 5 can drive the driving gear to rotate, and the gear body 4 meshes with the driving gear. The adjusting cylinder 3 can then drive the adjusting cylinder 3 to rotate accordingly, so as to facilitate the subsequent grinding and polishing of the bearing ring.

[0030] The clamping mechanism is arranged inside the adjusting cylinder 3 and is used for clamping according to the different sizes of the bearing rings; the clamping mechanism includes an adjusting screw 6, a connecting sleeve 7, an adjusting plate 8, a fixed base 9 and a clamping plate 10. The adjusting screw 6 is arranged inside the adjusting cylinder 3 and passes through one side of the adjusting cylinder 3. The connecting sleeve 7 is sleeved on the outer surface of the adjusting screw 6. The adjusting plate 8 is rotatably connected to the outer side of the connecting sleeve 7. The fixed base 9 is rotatably connected to the tail end of the adjusting plate 8. The clamping plate 10 is fixed to the outer side of the fixed base 9. The adjusting screw 6 can drive the connecting sleeve 7 to rotate. 7 can be adjusted left and right, and the fixed base 9 can be pushed by the adjusting plate 8 to slide and adjust. In cooperation with the clamping plate 10, it can be adjusted according to the size of the bearing ring, so that the application range of the equipment is further improved; the end of the adjusting cylinder 3 away from the adjusting screw rod 6 is evenly provided with a slide groove, and the fixed base 9 slides along the slide groove. The cross section of the clamping plate 10 is an arc-shaped structure. The slide groove can ensure the stability of the adjustment of the fixed base 9 and avoid the fixed base 9 from deflecting and shaking. Then, the clamping plate 10 is set in an arc shape, which can fit tightly with the bearing ring;

[0031] When in use, the bearing ring can be closely fitted with the side of the adjusting cylinder 3 close to the fixed base 9, and the adjusting screw 6 can be rotated clockwise. When the adjusting screw 6 rotates, the connecting sleeve 7 threadedly connected thereto can be pushed to slide to the left. Since the connecting sleeve 7 can slide, the fixed base 9 can be expanded outward through the adjusting plate 8, and the clamping plate 10 outside the fixed base 9 can contact the inner wall of the bearing ring, thereby limiting the position of the bearing ring for subsequent grinding.

[0032] The grinding chamber 12 is slidably connected to the upper end surface of the base body 1 and away from the inner side of the support frame 2. A grinding disc 15 is arranged inside the grinding chamber 12. A lifting screw 13 is arranged in the center of the grinding chamber 12. A positioning rod 14 is threadedly connected to the outer side of the lifting screw 13, and the other end of the positioning rod 14 is connected to the grinding disc 15. The positioning rod 14 can be slid up and down for adjustment, and the cross-section of the positioning rod 14 and the lifting screw 13 is an "L"-shaped structure. The lifting screw 13 can be rotated to adjust the position of the positioning rod 14, and the grinding disc 15 at one end of the positioning rod 14 can contact the inner wall or outer wall of the bearing ring. When the adjusting mechanism drives the adjusting cylinder 3 to rotate, the grinding can be carried out through the grinding disc 15, so that it can be adjusted according to the size and height of the bearing ring, and the subsequent polishing effect of the bearing ring can be guaranteed; the grinding chamber 12 is symmetrically provided with guide grooves 16 on the side close to the grinding disc 15, and the left and right sides of the grinding chamber 12 are slidably connected with filter chambers 17, and the side of the grinding chamber 12 away from the grinding disc 15 is provided with a fan body 18. The fan body 18 can guide the gas generated by grinding through the guide groove 16, and filter the gas through the filter chamber 17, which can avoid the gas from causing harm to the surrounding environment during the grinding process.
