[0024] The effect achieved by the entire embodiment 1 is that, when the inner diameter of the bearing 73 is detected, the second cylinder 41 is first started to drive the bevel plate 42 to move downward. At this time, the bevel inside the bevel plate 42 will squeeze the two rollers 44 and then drive the mounting plates 43 on both sides to approach each other. At this time, the measuring arms 61 under the mounting plates 43 will be received in the embedded grooves on both sides of the centering rod 6, and then the first cylinder 11 is started. After the first cylinder 11 is started, it will drive the second movable plate 13 to move downward through the first movable plate 12. During the descent of the second movable plate 13, it will squeeze the connecting plate 3 downward and then push the mounting frame 31 to move downward. At this time, the centering rod 6 formed as a whole with the mounting frame 31 will After moving downward, it is inserted into the inner ring of the bearing 73, and then the second cylinder 41 is started to drive the bevel plate 42 to move upward. The two rollers 44 lose the extrusion force. At this time, the tension spring 52 between the second connecting rod 51 and the first connecting rod 45 will shrink and pull the mounting plates 43 away from each other, so that the measuring arms 61 on both sides will collide with the inner wall of the bearing 73. At this time, the displacement sensor 53 will collect the moving distance data of the two mounting plates 43 and convert it into an electrical signal and display it on an external display device, so as to quickly and accurately detect the compliance of the inner diameter of the bearing 73, solving the problem of time-consuming and labor-intensive manual inspection and high re-inspection rate.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the support frame 1 is arranged in a T shape, the inner bottom of the support frame 1 is fixedly connected to the support leg 7, the top of the support leg 7 is fixedly connected to the storage plate 71, the outer surface of the storage plate 71 passes through the rear surface of the support frame 1 and extends to the front side, the top of the storage plate 71 is slidably provided with a push plate 72, and a bearing 73 is provided at the top of the storage plate 71 in front of the push plate 72.

[0026] The effect achieved by the entire embodiment 2 is that the supporting legs 7 are provided to play the role of installing the storage plate 71 under the supporting frame 1, and by placing the bearing 73 in the slot of the push plate 72, and then pushing the push plate 72 by an external cylinder, the bearing 73 can be sent to the bottom of the centering rod 6 for inspection. After the inspection is completed, the push plate 72 is continued to be pushed to make the bearing 73 fall into the collection mechanism placed below. The overall structure is simple and the degree of automation is high, which can greatly improve the inspection efficiency of the bearing 73.

[0027] Working principle: when the inner diameter of the bearing 73 is detected, the second cylinder 41 is first started to drive the bevel plate 42 to move downward. At this time, the bevel on the inner side of the bevel plate 42 will squeeze the two rollers 44 and then drive the mounting plates 43 on both sides to approach each other. At this time, the measuring arm 61 under the mounting plate 43 will be retracted into the embedded grooves on both sides of the centering rod 6, and then the first cylinder 11 is started. After the first cylinder 11 is started, it will drive the second movable plate 13 to move downward through the first movable plate 12. During the descent of the second movable plate 13, it will squeeze the connecting plate 3 downward and push the mounting frame 31 to move downward. At this time, the centering rod 6 formed as a whole with the mounting frame 31 will move downward and then be inserted into the inner ring of the bearing 73. Then, after the second cylinder 41 is started to drive the bevel plate 42 to move upward, the two rollers 44 lose the squeezing force, and at this time, the tension spring 52 between the second connecting rod 51 and the first connecting rod 45 will be contracted. After the mounting plates 43 are retracted and pulled away from each other, the measuring arms 61 on both sides come into contact with the inner wall of the bearing 73. At this time, the displacement sensor 53 collects the moving distance data of the two mounting plates 43 and converts it into an electrical signal and displays it on an external display device, thereby quickly and accurately detecting whether the inner diameter of the bearing 73 meets the standard, solving the problem that manual inspection is time-consuming and labor-intensive and the re-inspection rate is high. By setting the support legs 7, the storage plate 71 is installed under the support frame 1, and the bearing 73 is placed in the slot of the push plate 72, and then the push plate 72 is pushed by an external cylinder to send the bearing 73 to the bottom of the centering rod 6 for inspection. After the inspection is completed, continue to push the push plate 72 to make the bearing 73 fall into the collection mechanism placed below. The overall structure is simple and the degree of automation is high, which can greatly improve the inspection efficiency of the bearing 73.
