Description

[0001] The present application relates to the field of detection devices, and in particular to a bearing outer diameter detection device. Background Art

[0002] With the development of bearing detection technology, users have higher and higher requirements for the appearance quality of the outer surface of bearings, requiring the bearing surface to be glossy, free of rust and damage, without excessive or small chamfers, and without black skin and rust on the outer diameter surface. The consistency of the outer diameter of the bearing is a very important parameter for the bearing. If the outer diameter consistency is poor, the bearing noise will increase and the life will be reduced.

[0003] The existing technology of bearing outer diameter detection is still a combination of semi-automatic and manual detection. The outer diameter detection usually uses a mechanical diameter measuring instrument and is manually inspected. The specific process is to manually rotate the bearing for one circle during the inspection and then observe the changes in the readings of the measuring instrument. In addition to the errors of the measuring instrument itself, this measurement method also has measurement errors caused by the inspector's detection techniques, vision, technical level, etc., so the labor intensity is high and the detection quality is unstable.

The bearing 1 is limited by the clamping unit so that the bearing 1 will not move at will during the detection. The slide plate 5 is driven to move along the guide rail 4 by the movement of the piston rod of the vertical driving cylinder 18, so that the detection component on the slide plate 5 can move downward to detect the bearing 1, and the bearing 1 is automatically detected, thereby avoiding measurement errors caused by human factors such as detection techniques, vision, and technical level during manual detection, and making the detection result more accurate.

[0022] Please refer to Figure 1The detection assembly includes a detection cylinder 6, an elastic clamping arm 7, a push block 8, a roller 9, and a detection clamping claw 10. The detection cylinder 6 is fixedly installed on the top of the slide 5. The two elastic clamping arms 7 are respectively arranged on both sides of the front of the slide 5. A spring is arranged between the two elastic clamping arms 7 so that the two elastic clamping arms 7 have a tendency to approach each other. The push block 8 is arranged on the piston rod of the detection cylinder 6, and the shape of the push block 8 is an inverted cone. The two rollers 9 are symmetrically arranged on the two elastic clamping arms 7, and the two rollers 9 are in contact with the outer side of the push block 8. The two detection clamping claws 10 are respectively arranged at the bottom of the two elastic clamping arms 7. The detection clamping claws 10 are in contact with the bearing 1. The surface is arc-shaped and fits with the bearing 1. The piston rod of the detection cylinder 6 drives the push block 8 to move downward, so that the inverted cone-shaped push block 8 drives the two rollers 9 in contact with it to move toward each other, so that the detection jaws 10 at the bottom of the elastic clamping arm 7 move toward each other to the two sides of the bearing 1. The detection jaws 10 clamp the product. At the same time, the value of the detection jaws 10 when clamping is obtained through the micrometer. A certain error standard will be set in the system. The error range is qualified, otherwise it is unqualified, and the error range setting can be set by the controller. The bearing 1 is tested without manual testing, which improves the detection accuracy and avoids detection errors.

[0023] Please refer to Figure 1-Figure 5 The clamping unit includes a clamping plate 12, a vertical plate 13, a horizontal driving cylinder 14, a clamping slot 15, and a clamping platform 16. The clamping plate 12 is inserted and connected in the window 11. The clamping slot 15 is opened at one end of the clamping plate 12, and the bearing 1 can be clamped inside the clamping slot 15. The clamping platform 16 is arranged at one end of the clamping plate 12 close to the material moving plate 2, and the clamping platform 16 is used to clamp the material moving plate 2. The vertical plate 13 is arranged at the bottom of the clamping plate 12, and the vertical plate 13 is arranged on the back of the mounting plate 3. The horizontal driving cylinder 14 is arranged at the bottom of the front of the mounting plate 3. The piston rod of the horizontal driving cylinder 14 passes through the mounting plate 3 and is fixedly connected to the vertical plate 13. The material moving plate 2 is provided with a clamping The U-shaped bayonet 17 of the bearing 1 has three internal contact surfaces between the U-shaped bayonet 17 and the bearing 1, which can effectively wrap the outer side of the bearing 1. The horizontal driving cylinder 14 drives the clamping plate 12 to move horizontally so that the material transfer plate 2 can be clamped to prevent the material transfer plate 2 from driving the bearing 1 to shake and affect the detection accuracy. The diameter of the clamping groove 15 is slightly larger than the outer diameter of the bearing 1, and is used to position the bearing 1 for measurement to prevent displacement when the detection jaws 10 are clamped. During the operation, the clamping table 16 is used to clamp under the material transfer plate 2 and press it in the direction of the material transfer plate 2 to prevent the material transfer plate 2 from driving the bearing 1 to shake and affect the detection accuracy during the detection process.

[0024] This application can explain its functional principle through the following operation methods:

[0025] When in use, start the horizontal driving cylinder 14, so that the piston rod of the horizontal driving cylinder 14 drives the vertical plate 13 at the bottom of the clamping plate 12 to move, and drives the clamping plate 12 to move horizontally, so that the clamping groove 15 at one end of the clamping plate 12 is clamped under the material moving plate 2 and pressed toward the material moving plate 2. The bearing 1 inside the U-shaped clamping hole 17 on the material moving plate 2 is set in the clamping groove 15 on the clamping plate 12. The clamping groove 15 positions the bearing 1, and the bearing 1 is in the detection position to prevent the material moving plate 2 from driving the bearing 1 to shake during the detection process and affect the detection accuracy. Start the vertical driving cylinder 18 on the top of the mounting plate 3 so that the vertical driving The cylinder 18 drives the slide plate 5 to move downward along the guide rail 4, so that the detection claw 10 at the bottom of the elastic clamp arm 7 moves to the outside of the bearing 1, and the detection cylinder 6 is started, so that the piston rod of the detection cylinder 6 drives the inverted cone-shaped push block 8 to move upward. The elasticity between the two elastic clamp arms 7 makes the two rollers 9 always close to the outside of the push block 8. The two rollers 9 move closer to each other as the push block 8 moves upward, so that the inner wall of the detection claw 10 at the bottom of the elastic clamp arm 7 contacts the bearing 1. The micrometer obtains the value when the detection claw 10 is clamped, and the outer diameter of the bearing 1 is detected without manual work, which greatly improves the detection efficiency and detection accuracy.
