Description
Technical Field
[0001] This utility model relates to the field of bearing grinding fixtures, and in particular to a multi-angle grinding fixture for the inner ring of a bearing. Background Technology
[0002] A bearing is a mechanical component that restricts relative motion within the required range of motion and reduces friction between moving parts. The design of bearings can provide free linear motion or free rotation of moving parts around a fixed axis, or prevent motion by controlling the vector of the normal force acting on the moving parts. Grinding devices are widely used in the production process of mounted bearings. The existing bearing grinding devices have relatively simple internal and external structures, making it difficult to adjust the angle of the grinding rod according to the chamfer of the bearing. Grinding the inner wall of the bearing is particularly difficult. The general grinding method only performs unidirectional grinding, which easily leads to dead corners and low efficiency. Therefore, it cannot meet people's needs and needs to be improved.
[0003] Therefore, this application proposes a multi-angle grinding fixture for the inner ring of a mounted bearing to solve the problems in the background art.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

Figures 1-4 A multi-angle grinding fixture for the inner ring of a bearing with a seat includes a worktable 1, a limiting mechanism 3, and a grinding mechanism 5. The worktable 1 is equipped with a bearing 2 with a seat, and a limit mechanism 3 is provided on the worktable 1 and connected to the bearing 2 with a seat. A cylinder 4 is fixedly installed on the worktable 1, and a grinding mechanism 5 is provided at the output end of the cylinder 4. The grinding mechanism 5 is connected to the bearing 2 with a seat. A control panel 6 is provided on the worktable 1, and the limit mechanism 3, the grinding mechanism 5 and the cylinder 4 are all connected to the control panel 6. The grinding mechanism 5 includes a slide rail 51, a threaded rod 52, a mounting bracket 54, a grinding wheel 55, and a motor 56. The output end of the cylinder 4 is fixedly connected to the slide rail 51. Through the coordinated design between the worktable 1, the grinding mechanism 5, the cylinder 4, and the control panel 6, the inner ring of the bearing 2 with a seat can be ground from multiple angles, improving flexibility and processing efficiency.
[0021] In this embodiment, a threaded rod 52 is rotatably connected to the slide rail 51, and a slider 53 is threadedly connected to the threaded rod 52. A mounting bracket 54 is fixedly connected to the bottom of the slider 53, and a fixing rod is rotatably connected to one end of the mounting bracket 54. A grinding wheel 55 is mounted on the fixing rod, and the grinding wheel 55 abuts against the inner side of the bearing 2 with a seat, which facilitates the movement and adjustment of the grinding wheel 55.
[0022] In this embodiment, a rotating shaft 57 is rotatably connected to the mounting bracket 54. A motor 3 56 is fixedly mounted on one side of the mounting bracket 54, and its output end is fixedly connected to one end of the rotating shaft 57. The motor 3 56 is connected to the control panel 6. A motor 4 8 is fixedly mounted on one end of the slide rail 51. The output end of the motor 4 8 is fixedly connected to one end of the threaded rod 2 52. The motor 4 8 is connected to the control panel 6 and is used to drive the grinding wheel 55, thereby enabling it to grind the inner ring of the bearing 2.
[0023] In this embodiment, a drive wheel 58 is fixedly connected to one end of the rotating shaft 57 and the first fixed rod. The same drive belt 59 is connected to the two drive wheels 58 for transmission. A protective cover 7 is fixedly installed on one side of the mounting bracket 54. The protective cover 7 is sleeved on the drive belt 59 to provide protection.
[0024] In this embodiment, the limiting mechanism 3 includes a first motor 31, a first threaded rod 32, a first slider 33, a rubber roller 34, and a second motor 35. The first motor 31 is fixedly installed at the bottom of the worktable 1. The output end of the first motor 31 is fixedly connected to the first threaded rod 32. Both ends of the first threaded rod 32 are rotatably connected to a first fixing plate. Both first fixing plates are fixedly connected to the worktable 1 and are used to move and adjust the two rubber rollers 34, thereby limiting the inner ring of the bearings 2 of different specifications.
[0025] In this embodiment, both ends of the threaded rod 32 are threadedly connected to sliders 33. Rubber rollers 34 are rotatably connected to both sliders 33. Both rubber rollers 34 abut against the inner side of the bearing 2. The friction between the two rubber rollers 34 and the inner ring of the bearing 2 achieves the effect of limiting the inner ring of the bearing 2. Multiple bellows are sleeved on the threaded rod 32. The multiple bellows are located between the two fixed plates and the sliders 33, and their ends are fixedly connected to the two fixed plates and the sliders 33, respectively. They are used to protect the threaded rod 32 and prevent debris from affecting the threaded transmission between the threaded rod 32 and the two sliders 33.
[0026] In this embodiment, a motor 35 is fixedly installed on one of the two sliders 33. The output end of the motor 35 is fixedly connected to one end of one of the two rubber rollers 34. Both the motor 35 and the motor 31 are connected to the control panel 6 to drive the rubber roller 34 to rotate, thereby enabling the inner ring of the bearing 2 to rotate.
[0027] In this embodiment, a bracket is connected to the workbench 1, and the cylinder 4 is fixedly installed on the bracket. The threads at both ends of the threaded rod 32 are opposite, so that the two sliders 33 move in opposite directions.
[0028] Working principle: When in use, first connect the power supply and drive the cylinder 4, motor 1 31, motor 2 35, motor 4 8 and motor 3 56 through the preset program in the control panel 6. First, the bearing 2 with a mounting seat is placed on the worktable 1 and fitted onto two rubber rollers 34. Then, driven by the motor 31, the threaded rod 32 rotates and engages with the two sliders 33 via threaded transmission. This causes the two sliders 33 to move the two rubber rollers 34 and bring them into contact with the inner side of the bearing 2 with the mounting seat, thereby limiting the inner ring of the bearing 2. Afterward, driven by the motor 35, the corresponding rubber rollers 34 rotate and interact with the inner ring of the bearing 2, causing it to rotate. This facilitates the grinding wheel 55 to grind the inner ring of the bearing 2. At the same time, the rotating shaft 57 is driven by the electric motor 56 to rotate on the mounting bracket 54. Meanwhile, through the cooperation between the two transmission wheels 58 and the transmission belt 59, the fixed rod drives the grinding wheel 55 to rotate and act on the inner ring of the bearing 2, thereby achieving the effect of grinding the inner ring of the bearing 2. Driven by the motor 48, the threaded rod 52 rotates on the slide rail 51 and performs threaded transmission with the slider 53. The slider 53 drives the grinding wheel 55 to move horizontally through the mounting bracket 54, thereby achieving the effect of grinding different sizes of seated bearings 2. Meanwhile, the grinding wheel 55 can move up and down by the drive of the cylinder 4, and with the cooperation of the electric motor 8, it can achieve the effect of multi-angle grinding of the bearing 2 with seat. The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, it is not only possible to limit the positioning of bearings 2 of different sizes, but also to grind them from multiple angles, which improves convenience and applicability. Moreover, the structure is simple and more practical.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
