Description

Technical Field

[0001] This utility model relates to the field of bearing processing and testing technology, specifically a testing device for processing self-aligning roller bearings. Background Technology

[0002] Quality inspection of self-aligning roller bearings is of profound significance, serving as a crucial link in ensuring bearing performance and reliability. Rigorous testing allows for precise control of core parameters such as dimensional accuracy, rotational accuracy, and clearance, ensuring compliance with design standards and preventing operational jamming or excessive wear caused by dimensional deviations. Simultaneously, quality inspection can promptly detect potential problems such as surface defects and material cracks, preventing substandard products from entering the market and reducing the risk of equipment failure. Furthermore, high-quality inspection can optimize production processes, improve product consistency, and enhance enterprise competitiveness. For users, reliable bearing quality translates to longer service life, lower maintenance costs, and provides solid support for the stable operation of industrial equipment.

[0003] Utility model CN220794114U discloses a testing device for processing self-aligning roller bearings. Its structure includes a base, a testing platform on one side of the upper end of the base, a rotating assembly on the upper end of the testing platform, a positioning assembly on the upper end of the rotating assembly, and a slide on the other side of the upper end of the base. The upper end of the slide has a testing structure. The rotating assembly connects the rotating disk to the bearing and testing platform via a support rod. Rotating the rotating disk facilitates the rotation of the processed self-aligning roller bearing, making testing more convenient and stable, and reducing errors caused by rotation. The positioning assembly allows a frustum-shaped positioning platform to be mounted on the upper end of the rotating disk, enabling the fitting of self-aligning roller bearings of any size, effectively expanding the testing range of the device. Furthermore, the fixed magnet plate ensures more stable placement of the self-aligning roller bearing.

[0004] While the positioning platform of the aforementioned testing device can fix bearings of different specifications, its frustum shape and the cylindrical groove of the bearing inner ring make it difficult to ensure that the bearing mounted on the positioning platform does not shift. Multiple meticulous adjustments are required during bearing installation to avoid affecting the accuracy of the test results due to bearing misalignment. Furthermore, the aforementioned testing device requires manual rotation of the positioning platform to rotate the bearing for omnidirectional testing. This operation can easily cause overall structural wobbling during rotation, thus affecting the accuracy of the test results. Moreover, since the height of the testing structure cannot be adjusted, it is difficult to match bearings installed at different heights or to test different positions of the same bearing. Therefore, to address these problems, a testing device for self-aligning roller bearing processing is proposed. Utility Model Content

[0005] To address the technical problems in comparative technologies, such as the difficulty in ensuring that the bearing mounted on the positioning table does not shift and thus affect the test results, and the difficulty in performing comprehensive testing of bearings of different sizes using the testing structure, this utility model provides a testing device for self-aligning roller bearing processing.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is: A testing device for machining self-aligning roller bearings includes a support frame with a rotatably connected disc frame mounted on its top. The disc frame has several grooves arranged in a circumferential array, in which detachably connected jaw assemblies are installed. A drive mechanism is mounted on the support frame to drive the disc frame to rotate. An industrial camera facing the bearing is mounted on a testing frame. The jaw assembly includes a guide rail with a sliding block slidably disposed therein. A positioning locking element is fixedly disposed at the bottom of the sliding block, and a positioning locking groove that mates with the positioning locking element is formed at the bottom of the guide rail. A jaw mounting seat is mounted on the top of the sliding block, and an outwardly flared jaw piece is fixedly disposed on its upper end face. The bearing is sleeved on the outwardly flared jaw piece.

[0007] In one possible implementation, the positioning locking component includes a guide shaft fixedly disposed on the lower end face of the sliding block, a snap-fit ​​cylinder slidably disposed on the guide shaft, a cover fixedly connected to the bottom end of the snap-fit ​​cylinder, and a return spring sleeved on the lower side of the guide shaft.

[0008] In one possible implementation, the positioning locking groove includes a plurality of snap-fit ​​holes arranged in an array, the size of which matches the size of the snap-fit ​​cylinder, and all the snap-fit ​​holes are connected by a slide groove, the size of which matches the size of the guide shaft.

[0009] In one possible implementation, the upper end face of the sliding block is provided with a connecting groove, and the lower end face of the claw mounting base is fixedly provided with a connecting block corresponding to the connecting groove. The sliding block and the claw mounting base are fixedly connected by bolts passing through the connecting block. The end of the sliding block is provided with a positioning slot, and the end of the claw mounting base is fixedly provided with a positioning block corresponding to the positioning slot.

[0010] In one possible implementation, the inner wall of the guide rail is provided with a guide groove, and the two sides of the sliding block are fixedly provided with guide ridges corresponding to the guide groove.

[0011] In one possible implementation, the support frame includes a frame body with a bearing housing fixedly disposed at its top, and a rotating shaft is installed in the bearing housing.

[0012] In one possible implementation, the drive mechanism includes a servo motor, a drive wheel, and a driven wheel. The drive wheel is fixedly mounted on the output shaft end of the servo motor, and the driven wheel is fixedly mounted on the end of the rotating shaft. The drive wheel and the driven wheel are connected by a transmission belt.

[0013] In one possible implementation, the inspection frame is equipped with two sets of industrial cameras that are perpendicular to each other, one set of industrial cameras facing the front of the bearing and the other set of industrial cameras facing the side of the bearing.

[0014] In summary, this utility model has the following beneficial technical effects: In the jaw assembly, the outward-facing jaw pieces are used to fix and install the bearing. Specifically, several outward-facing jaw pieces arranged in a circumferential array can form a clamping structure for installing the bearing. When the bearing is fitted onto all the outward-facing jaw pieces, the outward-facing jaw pieces can support and fix the bearing, and ensure that its positive arrangement does not shift, which is convenient for visual inspection by industrial cameras. Moreover, since the position of the outward-facing jaw pieces can be adjusted by the cooperation of the sliding block and the positioning locking element, the diameter of the clamping structure formed by the outward-facing jaw pieces can be adjusted in multiple levels within a certain range to adapt to the installation and fixing of bearings of different sizes, making it very simple and convenient to use. In addition, the above-mentioned fixing method can ensure that the center point of the bearing tends to be constant during installation, thereby ensuring that bearings of various sizes can be directly facing the two sets of industrial cameras after installation, and ensuring that the installed bearing is located at the center of the visual range of the two sets of industrial cameras, thus ensuring the comprehensiveness of the inspection and the accuracy of the inspection results. Moreover, the servo motor can drive the bearing to rotate and hover at any angle, which is convenient for the industrial cameras to perform all-round visual inspection. Attached Figure Description

[0017] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: like Figure 1 - Figure 2 As shown, the self-aligning roller bearing processing inspection device provided in this embodiment includes a support frame 1, on which a rotating disk frame 2 is mounted. The disk frame 2 has a plurality of grooves 21 arranged in a circumferential array, in which a detachably connected claw assembly 3 is installed; a drive mechanism 4 is mounted on the support frame 1 to drive the disk frame 2 to rotate; and an inspection frame 5 on which an industrial camera 6 facing the bearing is mounted.

[0018] Based on the above structural scheme, the bearing to be inspected can be clamped and installed on the claw assembly 3 and positioned facing the industrial camera 6. The industrial camera 6 can complete the quality inspection of the bearing through visual inspection. During the inspection process, the drive mechanism 4 can drive the plate frame 2 to rotate, thereby driving the claw assembly 3 with the bearing installed to rotate and perform all-round inspection of the bearing.

[0019] Among them, such as Figure 3 As shown, the claw assembly 3 includes a guide rail 31, in which a sliding block 32 is slidably disposed. A positioning locking member 33 is fixedly disposed at the bottom end of the sliding block 32, and a positioning locking groove that cooperates with the positioning locking member 33 is opened at the bottom of the guide rail 31. A claw mounting seat 34 is installed at the top end of the sliding block 32, and an outwardly folding claw piece 35 is fixedly disposed on its upper end surface. The bearing is sleeved on the outwardly folding claw piece 35. Several outwardly folding claw pieces 35 arranged in a circumferential array can form a chuck structure for installing the bearing. When the bearing is sleeved on all the outwardly folding claw pieces 35, the outwardly folding claw pieces 35 can support and fix the bearing and ensure that its positive arrangement does not shift, which is convenient for the industrial camera 6 to perform visual inspection. Moreover, since the position of the outwardly folding claw piece 35 can be adjusted by the cooperation of the sliding block 32 and the positioning locking member 33, the diameter of the chuck structure formed by the outwardly folding claw piece 35 can be adjusted in multiple levels within a certain range to adapt to the installation and fixing of bearings of different sizes.

[0020] To ensure that the sliding block 32 is fixed in position after the sliding adjustment is completed, the positioning locking member 33 is used to fix its position, such as Figure 4 As shown, the positioning locking component 33 includes a guide shaft 333 fixedly mounted on the lower end face of the sliding block 32, on which a snap-fit ​​cylinder 331 is slidably mounted. A cover 332 is fixedly connected to the bottom end of the snap-fit ​​cylinder 331, and a return spring 334 is sleeved on the lower side of the guide shaft 333. Simultaneously, as a matching element, the positioning locking groove includes a plurality of snap-fit ​​holes 312 arranged in an array, the size of which matches the size of the snap-fit ​​cylinder 331. All the snap-fit ​​holes 312 are connected through a sliding groove 313, the size of which matches the size of the guide shaft 333. Based on the above-described design, when the snap-fit ​​cylinder 331 is located in the snap-fit ​​hole 312, due to… The two are interlocked, so the guide shaft 333 cannot be displaced, thus fixing the position of the sliding block 32 which is fixedly connected to the guide shaft 333. When the sliding block 32 needs to be slid to adjust its position, the dial cover 332 is pulled outward to separate the locking cylinder 331 from the locking hole 312. At this time, the guide shaft 333 can slide freely in the slide groove 313, so the position of the sliding block 32 can be adjusted freely. After the position adjustment is completed, the dial cover 332 is released and it will slide inward under the pushing force of the return spring 334, so that the locking cylinder 331 is inserted into the locking hole 312 of the guide shaft to complete the locking and fixing of the position.

[0021] like Figure 4 As shown, a connecting groove 322 is provided on the upper end face of the sliding block 32, and a connecting block 341 corresponding to the connecting groove 322 is fixedly provided on the lower end face of the claw mounting base 34. The sliding block 32 and the claw mounting base 34 are fixedly connected by bolts passing through the connecting block 341. A positioning groove 323 is provided at the end of the sliding block 32, and a positioning block 342 corresponding to the positioning groove 323 is fixedly provided at the end of the claw mounting base 34. In the above structural scheme, the matching of the connecting block 341 and the connecting groove 322, and the matching of the positioning block 342 and the positioning groove 323, can guide and position the installation of the claw mounting base 34, and can ensure the stability of its connection with the sliding block 32 after installation. The above scheme can realize the detachable connection between the outward-facing claw piece 35 and the sliding block 32, so that the fixing of bearings in a larger range can be covered by replacing sliding blocks 32 of different sizes.

[0022] like Figure 3 - Figure 4 As shown, the inner wall of the guide rail component 31 is provided with a guide groove 311, and the two sides of the sliding block 32 are fixedly provided with guide ribs 321 corresponding to the guide groove 311. The sliding engagement between the guide ribs 321 and the guide groove 311 can improve the stability of the sliding block 32 during sliding, making it less prone to shaking. This ensures that the outward-facing claw piece 35 installed on it does not shake, thereby ensuring its fixing effect on the bearing.

[0023] like Figure 5 As shown, the support frame 1 includes a frame body 11, with a bearing housing 12 fixedly installed at its top. A rotating shaft 13 is installed in the bearing housing 12. The above structure provides the necessary structural foundation for the rotational connection of the disc frame 2.

[0024] like Figure 5 As shown, the drive mechanism 4 includes a servo motor 44, a drive wheel 41, and a driven wheel 42. The drive wheel 41 is fixedly mounted on the output shaft end of the servo motor 44, and the driven wheel 42 is fixedly mounted on the end of the rotating shaft 13. The drive wheel 41 and the driven wheel 42 are connected by a transmission belt 43. When the bearing needs to be rotated, the servo motor 44 drives the driven wheel 42 to rotate through the drive wheel 41, thereby driving the rotating shaft 13, which is fixedly connected to the driven wheel 42, to rotate, so as to drive the disc frame 2. Finally, the drive claw assembly 3 rotates as a whole to drive the bearing mounted on it to rotate.

[0025] like Figure 1 As shown, two sets of industrial cameras 6 are installed on the inspection frame 5, which are perpendicular to each other. One set of industrial cameras 6 faces the front of the bearing, and the other set of industrial cameras 6 faces the side of the bearing. With the above arrangement, the front and side of the bearing can be inspected simultaneously, thereby improving the accuracy and comprehensiveness of the inspection results and improving the inspection efficiency.

[0026] The working principle and usage process of this utility model: A number of outward-facing claw pieces 35 arranged in a circumferential array can form a clamping structure for mounting bearings. When the bearing is fitted onto all the outward-facing claw pieces 35, the outward-facing claw pieces 35 can support and fix the bearing, and ensure that its positive arrangement does not shift, which is convenient for the industrial camera 6 to perform visual inspection. Moreover, since the position of the outward-facing claw pieces 35 can be adjusted by the cooperation of the sliding block 32 and the positioning locking member 33, the diameter of the clamping structure formed by the outward-facing claw pieces 35 can be adjusted in multiple levels within a certain range to adapt to the installation and fixing of bearings of different sizes.

[0027] For the positioning locking member 33, when the locking tube 331 is located in the locking hole 312, the two are locked together, so the guide shaft 333 cannot be displaced, thus fixing the position of the sliding block 32 which is fixedly connected to the guide shaft 333. When it is necessary to slide the sliding block 32 to adjust its position, the pull cover 332 is pulled outward to separate the locking tube 331 from the locking hole 312. At this time, the guide shaft 333 can slide freely in the slide groove 313, so the position of the sliding block 32 can be adjusted freely. After the position adjustment is completed, the pull cover 332 is released and it will slide inward under the pushing force of the return spring 334, so that the locking tube 331 is inserted into the locking hole 312 of the guide shaft to complete the locking and fixing of the position.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
