This reduces the labor intensity and labor cost of manual labor to a certain extent, improves the accuracy and reliability of the bearing inner diameter detection, and improves the detection efficiency.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1 , Figure 2 A bearing inner diameter detection device includes a moving plate 1 and a mounting plate 2 for transferring bearings to different detection stations. The mounting plate 2 is provided with a detection component for detecting the inner diameter of the bearing. The mounting plate 2 is also provided with a detection unit for driving the detection component to move vertically and a clamping unit for clamping the moving plate 1. The detection unit includes a guide rail 3, a slide plate 4 slidably arranged on the guide rail 3, and a vertical driving cylinder 19 for driving the slide plate 4 to move along the guide rail 3. There are two guide rails 3, which makes the slide plate 4 more stable during operation. The two guide rails 3 are arranged in parallel, the guide rails 3 are vertically mounted on the mounting plate 2, the slide plate 4 is horizontally arranged, the vertical driving cylinder 19 is fixedly mounted on the mounting plate 2, the output end of the vertical driving cylinder 19 is fixedly connected to the slide plate 4, the detection component is mounted on the slide plate 4, and the vertical driving cylinder 19 drives the slide plate 4 to move vertically and then drives the detection component to move vertically, so as to provide space for the moving plate 1 to transfer the bearing to the next station.

[0023] Reference Figure 1-Figure 3The detection assembly includes a detection cylinder 6, a detection spindle 7, and a stripping piece for separating the bearing from the detection spindle 7. The detection cylinder 6 is fixedly mounted on the upper surface of the slide plate 4 through a connecting plate 5. The detection spindle 7 is fixedly mounted on the output end of the detection cylinder 6. The detection spindle 7 is located below the slide plate 4. The outer diameter of the detection spindle 7 is adapted to the inner diameter of a bearing of a standard size. The detection spindle 7 is controlled to move vertically and inserted into the inner ring of the bearing to detect the inner diameter of the bearing. The stripping piece includes a connecting rod 8 and a stripping plate 9. The connecting rod 8 is arranged below the slide plate 4. The top end of the connecting rod 8 is fixedly connected to the lower surface of the slide plate 4. The bottom end of the connecting rod 8 is fixedly connected to the stripping plate 9, so that the stripping plate 9 is connected to the slide plate. 4 is fixed, the stripping plate 9 is arranged parallel to the slide plate 4, and a stripping port 10 is opened on the stripping plate 9 at a position corresponding to the detection spindle 7, the detection spindle 7 is plugged into the stripping port 10, and the diameter of the stripping port 10 is smaller than the outer ring diameter of the bearing. When detecting the inner diameter of the rotating shaft, the detection spindle 7 is first inserted into the stripping port 10 and then into the inner ring of the bearing. After the detection is completed, the detection cylinder 6 drives the detection spindle 7 to move upward. At this time, if there are convex points in the inner ring of the bearing or the inner diameter is too small, the bearing is easily taken away together. When the bearing follows the detection spindle 7 to rise to the position where it fits with the stripping plate 9, the bearing is blocked by the stripping plate 9, the detection spindle 7 continues to rise, and the detection spindle 7 is separated from the bearing.

[0024] Reference Figure 4 A through slot 15 is provided at the bottom end of the detection core shaft 7, and an elastic detection rod 16 is provided in the through slot 15. The elastic detection rod 16 is retractable and can roll in the through slot 15. The elastic detection rod 16 detects the inner diameter of the bearing from top to bottom, and reads the value of the inner diameter during detection through the inner diameter meter. A certain error standard will be set in the detection system. If it is within the error range, it is qualified, otherwise it is unqualified, and the error range can be manually set by the controller. The elastic detection rod 16 in the detection core shaft 7 will automatically detect the inner diameter of the bearing, and transmit the detection data to the detection system to determine whether the bearing is qualified, which reduces the labor intensity and labor cost of manual labor to a certain extent, improves the accuracy and reliability of bearing inner diameter detection, and improves the detection efficiency.

[0025] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 A clamping unit is also provided on the mounting plate 2, and the clamping unit includes a clamping plate 12, a vertical plate 13, a clamping platform 18, and a horizontal driving cylinder 14. A window 11 is opened on the mounting plate 2, and the clamping plate 12 is inserted into the window 11. The clamping platform 18 is fixedly installed on the end of the clamping plate 12 close to the material moving plate 1, and the vertical plate 13 is fixedly installed on the clamping plate 12. The vertical plate 13 and the clamping plate 12 are vertically arranged. The output end of the horizontal driving cylinder 14 is fixedly connected with the vertical plate 13. The horizontal driving cylinder 14 drives the clamping plate 12 to move horizontally toward the material moving plate 1, and the clamping platform 18 clamps the material moving plate 1 to prevent the material moving plate 1 from shaking during detection, which affects the accuracy of detection.

[0026] Reference Figure 1 , Figure 2 , Figure 6 A slot 17 for clamping the bearing is provided on the clamping plate 12. The diameter of the slot 17 is slightly larger than the outer diameter of the bearing and is used to limit the position of the bearing to prevent the detection spindle 7 from being displaced during detection. When the clamping platform 18 clamps the material transfer plate 1, the slot 17 is coaxially arranged with the detection spindle 7.

[0027] The working principle of the embodiment of the present application is: the material moving plate 1 sends the bearing into the clamping groove 17, the horizontal driving cylinder 14 drives the clamping plate 12 to move in the direction of the material moving plate 1, clamps the material moving plate 1 to prevent the material moving plate 1 from shaking during the detection process and affecting the detection accuracy, starts the vertical driving cylinder 19, and the vertical driving cylinder 19 drives the detection unit to move downward for a distance, and then starts the detection cylinder 6, and the detection cylinder 6 drives the detection spindle 7 to move, and the elastic detection rod 16 detects the bearing. After the detection is completed, the detection cylinder 6 drives the detection spindle 7 to move upward, so that the detection spindle 7 is separated from the bearing, and then starts the vertical driving cylinder 19, and the vertical driving cylinder 19 drives the slide plate 4 to move upward, providing space for the material moving plate 1 to transfer the bearing to the next workstation, which reduces the labor intensity and labor cost of manual labor to a certain extent, improves the accuracy and reliability of the bearing inner diameter detection, and improves the detection efficiency.
