Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to an automated bearing double-sided chamfering device. Background Technology

[0002] Bearings are essential components in machinery. They enable shafts to rotate stably. For example, car wheel axles and motor rotor shafts all require bearings to support them and ensure that rotating parts do not shift due to gravity or external forces during operation. Furthermore, by using rolling elements (such as balls and rollers) to roll between the inner and outer rings, sliding friction is transformed into rolling friction, significantly reducing frictional resistance. Bearings, like those in bicycle wheel axles, make riding easier.

[0003] During bearing manufacturing, the edges on both sides need to be chamfered. Chamfering reduces edge friction and obstruction when installing or removing bearings from mounting holes, shafts, or other components. However, current chamfering techniques require operators to hold the bearing and chamfer each side separately, making simultaneous chamfering of both sides inefficient. Furthermore, the close proximity of the chamfering tool to the operator poses a safety hazard. Utility Model Content

[0004] To address the technical problems in existing technologies, such as the inability to simultaneously chamfer both sides of a bearing and the safety hazards posed by the close proximity of the chamfering tool to the operator during the chamfering process, this utility model provides an automated double-sided chamfering device for bearings.

[0005] The automated bearing double-sided chamfering device provided by this utility model adopts the following technical solution: An automated bearing double-sided chamfering device includes a bracket and a cylinder rotatably mounted on the upper part of the bracket. A mounting sleeve for fixing the bearing is located on the side of the cylinder, and an automatic locking mechanism for automatically locking or unlocking the bearing is located between the mounting sleeve and the cylinder. The device also includes a chamfering mechanism for chamfering the bearing, which is mounted on the bracket.

[0012] By adopting the above technical solution, the bidirectional chamfering tool can be moved to the bottom of the bearing to perform double-sided chamfering on the bearing.

[0013] Furthermore, the automatic locking mechanism includes a drive assembly and a linkage locking assembly connected to the drive assembly.

[0014] By adopting the above technical solution, the mounting sleeve can automatically lock or unlock the bearing.

[0027] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0028] Example: Figures 1-4 The image shows an automated bearing double-sided chamfering device.

[0029] Reference Figures 1-4 As shown, this utility model discloses an automated bearing double-sided chamfering device, including a bracket 1 and a cylindrical body 2 rotatably disposed on the upper part of the bracket 1. The bracket 1 has a lower plate 12 and an upper plate 11. The cylindrical body 2 is rotatably disposed on the upper part of the upper plate 11. An installation sleeve 7 for fixing a bearing 8 is provided on the side of the cylindrical body 2. One side of the installation sleeve 7 is rotatably connected to the outer wall of the cylindrical body 2, and a locking head 71 for installing the bearing 8 is fixedly provided on the other side. An automatic locking mechanism 4 is provided between the installation sleeve 7 and the cylindrical body 2 to automatically lock or unlock the bearing 8. It also includes a chamfering mechanism 6 for chamfering the bearing 8. The chamfering mechanism 6 includes a bidirectional chamfering blade 62 that simultaneously chamfers both sides of the bearing 8 and a cylinder 61 that drives the bidirectional chamfering blade 62 to move upward and contact the bearing 8. The cylinder 61 is fixedly installed on the upper part of the upper plate 11. The bidirectional chamfering blade 62 is fixedly installed on the top of the push rod in the cylinder 61. A chamfering blade is located at the top of the bidirectional chamfering blade 62 to simultaneously chamfer the edges of both sides of the bearing 8. It also includes an automatic rotation mechanism 5 that rotates the bearing 8 during chamfering. The automatic rotation mechanism 5 is disposed between the mounting sleeve 7 and the cylinder 2.

[0030] Reference Figures 3-4 As shown, the automatic locking mechanism 4 includes a drive component and a linkage locking component connected to the drive component. The drive component drives the linkage locking component to move, so that the mounting sleeve 7 locks or unlocks the position of the bearing 8.

[0031] Preferably, the linkage locking assembly includes a locking rod 45 disposed inside the mounting sleeve 7 and a bevel gear 44 screwed to the end of the locking rod 45. One end of the locking rod 45 is threaded, and the other end is rotatably connected to a tapered pin 451. A locking head 71 is fixedly connected to the end of the mounting sleeve 7. The locking head 71 has multiple adjusting grooves evenly distributed at its end, and a tapered adjusting hole is located inside the locking head 71. The ends of the adjusting grooves and the adjusting hole are interconnected. The tapered pin 451 is slidably disposed in the tapered adjusting hole in the locking head 71. The bevel gear 44 is rotatably disposed within the tapered adjusting hole in the locking head 71. The inner wall of the cylinder 2 is threaded to the end of the locking rod 45. In use, the bearing 8 is sleeved on the outside of the locking head 71. By rotating the bevel gear 44 in the forward direction, the tapered pin 451 can move forward inside the locking head 71 and push the locking head 71 outward. The outer wall of the locking head 71 expands outward to lock the bearing 8. By rotating the bevel gear 44 in the reverse direction, the tapered pin 451 can move backward inside the locking head 71, so that the tapered pin 451 no longer pushes against the outer wall of the locking head 71. The outer wall of the locking head 71 retracts inward under its own elastic force, unlocking the thread. The drive assembly includes a first arc-shaped toothed plate 42 that moves the locking rod 45 forward and a second arc-shaped toothed plate 43 that moves the locking rod 45 backward. The first arc-shaped toothed plate 42 and the second arc-shaped toothed plate 43 are symmetrically arranged inside the cylinder 2. Preferably, a connecting column 41 is fixedly arranged inside the cylinder 2. The bottom of the connecting column 41 is fixedly connected to the top of the lower plate 12. The first arc-shaped toothed plate 42 and the second arc-shaped toothed plate 43 are fixedly arranged on the upper part of the connecting column 41. The first arc-shaped toothed plate 42 meshes with the top of the bevel gear 44, and the second arc-shaped toothed plate 43 meshes with the bottom of the bevel gear 44. In use, the first arc-shaped toothed plate 42 drives the bevel gear 44 to rotate forward to lock the bearing 8, and the second arc-shaped toothed plate 43 drives the bevel gear 44 to rotate in the opposite direction to unlock the bearing 8.

[0032] Furthermore, an internal gear ring 21 is located on the inner wall of the bottom of the cylinder 2, and a bottom gear 32 is located inside the cylinder 2 that meshes with and drives the internal gear ring 21 to rotate. A bottom motor 31 is provided on the lower plate 12 to drive the bottom gear 32 to rotate. In use, the bottom motor 31 drives the bottom gear 32 to rotate, and the bottom gear 32 drives the cylinder 2 to rotate through the internal gear ring 21, so that the first arc-shaped toothed plate 42 and the second arc-shaped toothed plate 43 can mesh with the top and bottom of the bevel gear 44 in sequence, driving the bevel gear 44 to rotate in the forward and reverse directions.

[0033] Reference Figure 4As shown, the automatic rotation mechanism 5 includes a driven gear 51 fixedly mounted on the outer wall of the mounting sleeve 7 and a main gear 52 meshing with the driven gear 51. The main gear 52 is rotatably mounted on the outer wall of the cylinder 2. An internal motor 53 is located inside the cylinder 2 to drive the main gear 52 to rotate. In use, when the bidirectional chamfering cutter 62 contacts the bearing 8 on the mounting sleeve 7, the internal motor 53 drives the main gear 52 to rotate. The main gear 52 drives the mounting sleeve 7 to rotate through the driven gear 51, and the mounting sleeve 7 drives the bearing 8 to rotate and chamfer.

[0034] When using this invention for chamfering, the bearing 8 is fitted onto the locking head 71 in the mounting sleeve 7. The bottom motor 31 is started, causing the cylinder 2 to rotate. During rotation, the bevel gear 44 in the automatic locking mechanism 4 meshes with the first arc-shaped toothed plate 42. Under the resistance of the first arc-shaped toothed plate 42, the bevel gear 44 rotates forward, causing the locking rod 45 to move forward. This causes the outer wall of the locking head 71 to expand outward and clamp the bearing 8. At this time, the cylinder 2 moves the bearing 8 above the chamfering mechanism 6. The cylinder 61 in the chamfering mechanism 6 drives the bidirectional chamfering cutter 62 to move upward and engage with the bearing 8. The two sides make contact, and then the internal motor 53 in the automatic rotation mechanism 5 is started. The internal motor 53 drives the mounting sleeve 7 to rotate through the main gear 52, so that the bearing 8 rotates and is chamfered. After chamfering, the bottom motor 31 drives the cylinder 2 to continue to rotate, so that the bottom of the bevel gear 44 meshes with the second arc-shaped toothed plate 43. Under the resistance of the second arc-shaped toothed plate 43, the bevel gear 44 is driven to rotate in the opposite direction to unlock the bearing 8. Using this equipment, the two sides of the bearing 8 can be chamfered automatically, which improves the chamfering efficiency. Moreover, no manual operation is required during chamfering, which prevents the safety hazards of the chamfering knife to the operator.
