Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. When a bearing is just produced, there are many burrs on its surface, so it needs to be ground before use.

[0003] Existing grinding equipment usually has a relatively simple structure and cannot fully handle the burr problems on the outer surface and inner wall surface of the bearing. Therefore, grinding treatment is required. In actual operation, workers often need to manually adjust the position of the grinding mechanism to adapt to different parts of the bearing, which not only increases the complexity of the operation but also may lead to differences in the grinding effect on bearings of different models. In addition, traditional equipment usually requires manual feeding and clamping of the bearing. If the bearing clamping and positioning are not accurate, it will directly affect the grinding accuracy, increase the error of the bearing, and manual alignment of the clamping structure is also a time-consuming and cumbersome task.

There are two sets of slide rails 8 which are respectively located on the base surface of the installation base 1, and the stability is better when the first fixing plate 6 moves.

[0029] When the bearing grinding device for processing this solution works, the drive shaft of the second drive motor 902 penetrates through the bottom plate 901 and extends to the outer wall of the bottom plate 901, where a threaded connecting rod 903 is connected. A second connecting block 904 is threadedly connected to the outer wall of the threaded connecting rod 903. One end of the second connecting block 904 is slidably connected to a slide rod 905, and one end of the slide rod 905 is connected to the outer wall of the bottom plate 901. Under such circumstances, only need to turn on the controller 907 to make the controller 907 control the operation of the second drive motor 902. The second drive motor 902 drives the threaded connecting rod 903 to rotate. The threaded connecting rod 903 drives the fixed bracket 906 to move horizontally through the second connecting block 904. At the same time, a third drive motor 909 is installed on the outer wall of the connecting bracket 908. A threaded connecting rod 910 is installed on the drive shaft of the third drive motor 909. One end of the threaded connecting rod 910 penetrates through the fixed bracket 906 and extends to the inner wall of the fixed bracket 906, where a limit block 911 is installed. A sliding rod 912 is slidably connected to the opposite outer walls of the limit block 911. One end of the sliding rod 912 is connected to the inner wall of the fixed bracket 906. Under such circumstances, the controller 907 controls the operation of the third drive motor 909. The third drive motor 909 drives the threaded connecting rod 910 to rotate. Then the threaded connecting rod 910 drives the grinding motor 913 to move vertically through the limit block 911, so that the grinding motor 913 moves along the XZ axis under the action of the second drive motor 902 and the third drive motor 909. The controller 907 controls the operation of the grinding motor 913. The grinding motor 913 drives the grinding block 914 to grind the surface of the bearing part 1105. Subsequently, one end of the threaded rod 3 penetrates through the mounting block 2 and extends to the outer wall of the mounting block 2, where a first drive motor 4 is connected. A first connecting block 5 is threadedly connected to the outer wall of the threaded rod 3. A first fixing plate 6 is installed on the outer wall of the first connecting block 5. A slider 7 is installed at the bottom of the first fixing plate 6. The outer wall of the slider 7 is slidably connected to a slide rail 8, and the slide rail 8 is installed on the base surface of the mounting base 1. The controller 907 controls the operation of the first drive motor 4. The first drive motor 4 drives the threaded rod 3 to rotate. Then the threaded rod 3 drives the first fixing plate 6 to move along the Z axis through the first connecting block 5. When the grinding motor 913 moves to a suitable position, the first fixing plate 6 drives the grinding assembly 9 to move along the Z axis, and then the grinding motor 913 drives the grinding block 914 to grind the inner cavity surface of the bearing part 1105, thus solving the problem that the existing grinding equipment usually has a relatively simple structure and cannot fully cope with the burr problems on the outer surface and inner wall surface of the bearing. Therefore, grinding treatment is required. In actual operation, workers often need to manually adjust the position of the grinding mechanism to adapt to different parts of the bearing, which not only increases the complexity of the operation but also may cause differences in the grinding effect on bearings of different models.

[0030] An infrared position sensor 1106 is provided on one side of the bearing member 1105 and on the outer wall of the second fixing plate 1102. Under the action that the infrared position sensor 1106 is located on one side of the arc-shaped base 1104, when the bearing member 1105 is placed on the base surface of the arc-shaped base 1104, since the bearing member 1105 blocks the infrared position sensor 1106, the infrared position sensor 1106 generates an electrical signal and conducts it to the controller 907 through a wire. When the set value is reached, the controller 907 controls the operation of the electric fixture 1101. At the same time, an arc-shaped clamping block 1103 is provided at one end of the electric fixture 1101. The second fixing plate 1102 is installed on the outer wall of the mounting bracket 10. An arc-shaped base 1104 is installed on the outer wall of the second fixing plate 1102, and the arc-shaped base 1104 is located directly below the arc-shaped clamping block 1103. Under the action that the bearing member 1105 is installed on the inner wall of the arc-shaped base 1104, the electric fixture 1101 drives the arc-shaped clamping block 1103 to move downward. Since both the arc-shaped clamping block 1103 and the arc-shaped base 1104 are arc-shaped structures, when the arc-shaped clamping block 1103 moves towards the arc-shaped base 1104, the bearing member 1105 is clamped between the arc-shaped clamping block 1103 and the arc-shaped base 1104 for fixation. The device automatically clamps, and the fixture has its own limit, making the installation of the bearing member 1105 in place convenient for subsequent grinding, thus solving the problem that traditional equipment usually requires manual feeding and clamping of bearings. If the bearing clamping and positioning are not accurate, it will directly affect the grinding accuracy, increase the error of the bearings, and manual alignment of the clamping structure is also a time-consuming and cumbersome task.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
