Description

[0001] This application is a divisional application of the application filed on October 19, 2023, with application number 202311358461.1 and invention name “A bearing inner ring inner diameter detection device for bearing processing and manufacturing”. Technical Field

[0002] The invention relates to the technical field of bearing processing and manufacturing, and in particular to a bearing inner ring inner diameter detection device used for bearing processing and manufacturing. Background Art

[0003] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. During the production and processing of bearings, it is essential to detect the bearing aperture (such as inner diameter and outer diameter).

[0004] At present, when the inner diameter of the inner ring of the bearing is detected, the inner ring aperture detection equipment of the bearing shown in the application publication number CN114199177A includes a workbench assembly, and a detection mechanism is fixedly installed on the top of the workbench assembly. Although it realizes the detection of the inner diameter of the inner ring of the bearing, during the detection process, the bearing needs to be fixed first, and the bearing can be detected only after the bearing is fixed. The fixing and detection of the bearing are carried out separately, resulting in a long time for the entire detection process and low detection efficiency. At the same time, after the detection is completed, the bearing must be removed before the next group of detection can be carried out. When more bearings need to be detected, the time used for removing and placing the bearings is long, which further affects the overall detection efficiency. Summary of the invention

The detection conical head, T-shaped column, hydraulic rod and bearing positioning column are all coaxially arranged.

[0014] Preferably, the buffer parts are arranged in three groups in a circular array on the outside of the T-shaped column. The buffer parts include a buffer column with one end fixed to the top surface of the detection cone head and the other end sliding through the T-shaped column, and a buffer spring sleeved on the outside of the buffer column.

The detection camera then takes a photo to detect the position of the detection slider, thereby realizing automation during detection without manual reading, and further improving the efficiency of the entire detection process.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Reference Figure 1-3 A bearing inner ring inner diameter detection device for bearing processing and manufacturing includes a processing table 1 and a U-shaped detection bracket 2 fixed on the top surface of the processing table 1, and the two sides of the detection bracket 2 are used for operation by the staff. A rotating disk 6 is rotatably installed in the middle of the top surface of the processing table 1, and a motor 10 that drives the rotating disk 6 is installed inside the processing table 1. The rotating disk 6 can be rotated on the processing table 1 by the motor 10, and the motor 10 rotates one-fourth of the rotating disk each time. The rotating disk 6 is hollow, and the top surface of the rotating disk 6 is provided with four bearing placement grooves 7 in a circular array. The bearing placement grooves 7 are used to place bearings. A through hole is opened in the middle of each bearing placement groove 7, and a bearing positioning column 8 is coaxially arranged in the through hole. When the bearing is placed, the bearing can be directly sleeved on the outside of the bearing positioning column 8 without fiddling with the bearing, and the operation is simple. Guide grooves 11 are symmetrically opened on both sides of each bearing placement groove 7, and a bearing clamp 9 is arranged in the guide groove 11. The bearing clamp 9 slides along the guide groove 11. , clamped on both sides of the bearing to fix the bearing firmly, connecting parts are provided on both sides of the bottom end of the bearing positioning column 8 and the two symmetrically arranged bearing clamping plates 9. When the bearing positioning column 8 is raised or lowered, the connecting parts can drive the bearing clamping plates 9 to move left and right, and a rebound part supporting the bearing positioning column 8 is installed inside the rotating disk 6. The rebound part not only supports the bearing positioning column 8, but also can rebound it when the bearing positioning column 8 moves downward to achieve automatic recovery. Two hydraulic rods 3 are embedded in the middle of the detection bracket 2, and the bottom end of each hydraulic rod 3 is connected to a detection head module 4 coaxially arranged with the bearing positioning column 8. The two inner sides of the detection bracket 2 are installed with detection cameras 5 facing the adjacent detection head modules 4 respectively. The detection camera 5 can be connected to a computer externally, so that the computer can judge the specific detection value when taking pictures.

[0033] Reference Figure 1-3 The guide groove 11 is connected to the through hole in the middle of the bearing placement groove 7, so as to maximize the sliding distance of the bearing clamp plate 9. A guide column 12 fixed horizontally is arranged inside the guide groove 11. The lower end of the bearing clamp plate 9 fits through the guide groove 11 and slides on the outer side of the guide column 12. The use of the guide column 12 ensures the stability of the bearing clamp plate 9 when sliding horizontally. On the other hand, refer to Figure 4The upper end of the bearing clamping plate 9 is arranged in an arc shape on one side facing the through hole, and the arc surface is convenient for contacting with the side of the bearing. At the same time, a rubber pad is bonded to the arc surface during use to increase the friction with the bearing surface and maximize the stability of the bearing when clamped.

[0034] Referring to 4-6, two ear plates 16 are installed on the side of the lower end of the bearing clamp plate 9 facing the bearing positioning column 8, the connecting piece is fixed to the connecting plate 17 at the bottom end of the bearing positioning column 8 and the connecting rod 15 is hinged on both sides of the connecting plate 17, and the end of the connecting rod 15 away from the connecting plate 17 is hinged between the two ear plates 16 at the lower end of the bearing clamp plate 9. Since the two ends of the connecting rod 15 are respectively hinged to the connecting plate 17 and the bearing clamp plate 9, when the connecting plate 17 moves up and down, the connecting rod 15 is pulled to tilt, thereby driving the corresponding movement of the bearing clamp plate 9.

[0035] Reference Figure 5-7 The bearing positioning column 8 includes an outer lifting tube 81 located on the outside and a limiting inner tube 82 located on the inside. The lifting outer tube 81 is threadedly sleeved on the outside of the limiting inner tube 82. The lifting outer tube 81 can be rotated to adjust the vertical length of the entire bearing positioning column 8, and then adjust the distance between the bearing positioning column 8 and the detection head module 4. When the bearing to be detected is large, the distance between the bearing positioning column 8 and the detection head module 4 is increased, so that the detection head module 4 is lowered for a longer distance to squeeze the bearing positioning column, and then the bearing positioning column 8 drives the bearing clamp 9 to clamp the bearing. When the bearing to be detected is small, the distance that the bearing clamp 9 needs to move becomes longer, and the distance between the bearing positioning column 8 and the detection head module 4 is adjusted to be smaller, so that the detection head module 4 can contact the bearing positioning column 8 after a shorter distance is lowered, and the bearing positioning column 8 is pressed down. The inner part of the limiting inner tube 82 is provided with a tube hole with a regular hexagonal cross section, and the connecting plate 17 is provided with a through hole connected to the tube hole. The rebound member includes a supporting bottom column 13 fixed to the inner bottom wall of the rotating disk 6 and a restoring spring 14 sleeved on the outside of the supporting bottom column 13. The top end of the supporting bottom column 13 passes through the through hole on the connecting plate 17 to the limiting inner tube 82, and is connected to a clamping plate that is clamped with the tube hole. The supporting bottom column 13 is clamped in the limiting inner tube 82 by the clamping plate, so that the limiting inner tube 82 remains stable when sliding vertically. The top end of the restoring spring 14 abuts against the bottom surface of the connecting plate 17, and the restoring spring 14 is squeezed when the bearing positioning column 8 moves downward.

[0036] Reference Figure 8-9The detection head module 4 includes a T-shaped column 41 fixed to the bottom surface of the hydraulic rod 3, a buffer connected to the outside of the T-shaped column 41, and a detection cone head 42 connected to the end of the buffer away from the T-shaped column 41. The detection cone head 42 is set in a cone shape. When entering the inner ring of the bearing, the length of the extension into the inner ring of the bearing can be different according to the size of the inner ring of the bearing, and then the specific size of the inner ring of the bearing can be judged according to the extension length. The detection cone head 42, the T-shaped column 41, the hydraulic rod 3 and the bearing positioning column 8 are all coaxially arranged to ensure that when the detection cone head 42 moves downward, it can also be coaxially arranged with the bearing, thereby ensuring the accuracy of the detection.

[0037] Reference Figure 8-9 There are three groups of buffers arranged in a circular array on the outside of the T-shaped column 41. The buffers include a buffer column 43 with one end fixed on the top surface of the detection cone head 42 and the other end sliding through the T-shaped column 41, and a buffer spring sleeved on the outside of the buffer column 43. The top of the buffer column passes through the T-shaped column 41 and is connected to a retaining ring to ensure that the retaining ring is in contact with the T-shaped column 41 in a normal state to ensure that the detection cone head 42 does not fall off. At the same time, when the detection cone head 42 is subjected to impedance force, the buffer spring can be compressed upward. In the actual detection process, how to judge whether the detection cone head 42 has extended into the inner ring of the bearing and no longer extends further can be judged by pressing down and rebounding upward when it is no longer extended.

[0038] The top surface of the detection cone head 42 is located between the three buffer parts and a pressure sensor 44 is installed. In a normal state, the top surface of the pressure sensor 44 does not contact the T-shaped column 41. When the detection cone head 42 moves upward and compresses the buffer spring, the pressure sensor 44 contacts upward. When it contacts the T-shaped column 41, the pressure sensor 44 is subjected to pressure, thereby triggering the controller to work. At this time, it is judged that the detection cone head 42 is pressed down to the inner ring of the bearing and is no longer pressed down. The pressure sensor 44 is electrically connected to the hydraulic rod 3 and the detection camera 5 through the controller. After the pressure sensor 44 is subjected to pressure, the corresponding signal is transmitted. The controller then stops the extension and retraction of the hydraulic rod 3 according to the signal, and starts the detection camera 5 to take pictures to record the detection values.

[0039] Detection ruler grooves 45 are provided on the two side surfaces of the detection cone head 42 opposite to the detection camera 5. The detection ruler grooves 45 are provided with corresponding values ​​for judging the outer diameter of the detection cone head 42 at different positions. A detection slider 46 is provided for sliding in the detection ruler groove 45. The detection ruler groove 45 is T-shaped. One end of the detection slider 46 in the detection ruler groove 45 protrudes outward and fits on both ends of the T-shape to ensure that the detection slider 46 will not fall off when sliding on the detection ruler groove 45. A concave hole 47 matched with the bearing positioning column 8 is drilled upward on the bottom surface of the detection cone head 42. The setting of the concave hole 47 is used to enable the bearing positioning column 8 to be inserted into the concave hole 47 when the detection cone head 42 moves downward, which will not affect the detection cone head 42 from entering the inner ring of the bearing downward.

[0040] The specific working principle of the present invention is as follows:

[0041] When inspecting the inner ring of the bearing, the staff stand on both sides of the processing table 1, place the bearings in the bearing placement grooves 7 that are not vertically corresponding to the detection head module 4, and put the bearings on the outside of the bearing positioning column 8. After the placement is completed, start the motor 10 to rotate 90°. The motor 10 rotates 90° to drive the rotating disk 6 to rotate 90° on the processing table 1, so that the bearing placement groove 7 with the bearing placed is rotated to the bottom of the detection head module 4, and the empty bearing placement groove 7 is rotated in front of the staff. At this time, the workers continue to place new bearings into the empty bearing placement groove 7, and start the hydraulic rod 3 at the same time. The hydraulic rod 3 begins to extend and drives the detection head module 4 to descend;

[0042] When the detection head module 4 descends, the detection cone head 42 moves downward. The bearing positioning column 8 enters the recessed hole 47 and contacts the top surface of the recessed hole 47. The detection cone head 42 starts to drive the bearing positioning column 8 to move downward. The bearing positioning column 8 moves downward, driving the connecting plate 17 to compress the restoring spring 14 downward, and driving the connecting rod 15 downward. The connecting rod 15 pulls the two bearing clamps 9 toward the bearing until the bearing clamps 9 clamp the outer ring of the bearing. At this time, the connecting plate 17 and the bearing positioning column 8 no longer move downward, and the detection cone head 42 continues to move downward. Due to the immobility of the bearing positioning column 8, the detection cone head 42 begins to compress the buffer spring upward. When the detection cone head 42 enters the inner ring of the bearing, the position The detection slide at the bottom is blocked above the inner ring and starts to slide upward along the detection ruler groove 45 until the pressure sensor 44 contacts the T-shaped column 41. The hydraulic rod 3 stops extending, and the detection camera 5 starts to take pictures of the position of the detection slider 46, and determines the size of the inner ring of the bearing by the corresponding readings on the detection ruler groove 45. Then the hydraulic rod 3 contracts, driving the detection head module 4 to start restoring. At the same time, the connecting plate 17 and the bearing positioning column 8 begin to recover due to the rebound of the recovery spring 14. The two bearing clamps 9 also recover and release the bearings. The motor 10 rotates 90° again to align the detected bearings with the staff. The new bearing to be tested is moved to the bottom of the detection head module 4 to start the detection of the next group of bearings.

[0043] In the above operation steps, when the bearing positioning column 8 is no longer moving downward and the bearing clamp 9 has clamped the bearing, at this time, even if the detection cone head 42 can continue to extend downward into the inner ring of the bearing, in the process of continuing to move downward, the detection cone head 42 has begun to compress the buffer spring upward. In order to ensure that when the pressure sensor 44 is triggered at this time, the detection cone head 42 completes the detection of the inner ring of the bearing, the vertical length of the bearing positioning column 8 can be adjusted according to bearings of different sizes in actual use to ensure that even if the bearing positioning column 8 is no longer pressed down, when the pressure sensor 44 is triggered, the detection cone head 42 has been pressed down to the deepest position in the inner ring of the bearing.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
