[0043] refer to Figure 1 - Figure 5 As shown:

[0044] The embodiment of the present invention provides a bearing inner ring raceway diameter detection device, comprising a base 100, at least two spring-type connecting plates 200, a rotating assembly 300 for driving a bearing inner ring 600 to rotate, and a loading assembly 400 for loading and unloading materials; the spring-type connecting plates 200 are located on the base 100, and the rotating assembly 300 is located above the base 100; both ends of the base 100 are provided with mounting seats 110 corresponding to the spring-type connecting plates 200, and the mounting seats 110 are provided with tension springs 120, and both ends of the spring-type connecting plates 200 are connected to the tension springs 120. The mounting seat 110 is provided with a power source 130 for driving the spring-clip connecting plate 200 to move; the spring-clip connecting plate 200 is provided with a measuring contact 210 for measuring the bearing inner ring 600, and the mounting seat 110 is provided with a contact digital sensor 140 abutting against the spring-clip connecting plate 200; a measuring pad 500 is provided above the spring-clip connecting plate 200, and a positioning contact 510 and a fulcrum seat 520 are provided on the measuring pad 500, and the height of the bearing inner ring 600 when located on the feeding assembly 400 is lower than the height of the bearing inner ring 600 when located on the fulcrum seat 520.

[0045] When in use, the inner ring 600 of the bearing is transported to the fulcrum seat 520 through the loading assembly 400, the positioning contact 510 on the measuring pad 500 will support the inner ring 600 of the bearing, and then the spring connecting plate 200 is driven by the power source 130, so that the measuring contact 210 set on the spring connecting plate 200 contacts the inner ring 600 of the bearing, and the contact digital sensor 140 abutting against the spring connecting plate 200 will measure the data, and then the rotating assembly 300 will drive the inner ring 600 of the bearing to rotate, and the inner ring 600 of the bearing will not be separated from the fulcrum seat 520 during the rotation process, and the inner ring 600 of the bearing is restricted by the positioning contact 510, the measuring contact 210 and the loading assembly 400 to avoid errors in the rotation measurement, and the contact digital sensor 140 will measure the diameter runout data of the inner ring 600 of the bearing. Through such a setting, the inner ring 600 of the bearing can be automatically measured, the measurement accuracy is guaranteed, and the work efficiency is greatly improved.

[0046] Among them, the height of the bearing inner ring 600 when it is located on the loading assembly 400 is lower than the height of the bearing inner ring 600 on the fulcrum seat 520. Specifically, the height of the bearing inner ring 600 on the fulcrum seat 520 is 0.1 mm higher than the height of the bearing inner ring 600 when it is located on the loading assembly 400, and the top of the fulcrum seat 520 has a smooth transition. When the loading assembly 400 drives the bearing inner ring 600 to enter the fulcrum seat 520, the bearing inner ring 600 will transition from being supported by the loading assembly 400 to being supported by the fulcrum seat 520 (the loading assembly 400 does not perform a reset action), and then the measurement work is carried out.

[0047] When the bearing inner ring 600 is transferred from the loading assembly 400 to the fulcrum seat 520, the positioning contact 510 provided on the measuring pad 500 will abut against the bearing inner ring 600, and the loading assembly 400 will support the bearing inner ring 600, and then the power source 130 drives the spring connecting plate 200 to move, thereby driving the measuring contact 210 on the spring connecting plate 200 to perform the measurement work. In the process of measuring the bearing inner ring 600, the bearing inner ring is fixed by the positioning contact 510 and the loading assembly 400 to prevent the bearing inner ring 600 from deflecting (the measuring method is the standard part comparison method, the positioning contact 510 is adjusted and fixed, and then the standard part is measured according to the above process, the data is recorded, and then the workpiece is measured directly with the standard part measurement data). Such a setting ensures the stability and accuracy of data measurement.

[0048] Among them, a contact digital sensor 140 is provided on the mounting seat 110 and is in contact with the spring-clip connecting plate 200. The contact digital sensor 140 is in contact with the spring-clip connecting plate 200. When the measuring contact 210 is displaced in contact with the inner ring 600 of the bearing, the measuring contact 210 will drive the spring-clip connecting plate 200 to change its displacement, thereby triggering the contact digital sensor 140, so that the contact digital sensor 140 can measure data, and then use the measured data to compare with the standard part data.

[0049] In an optional solution of this embodiment, a groove 101 is opened on the base 100 , and a plurality of spring-type connecting plates 200 are all located in the groove 101 ; and the mounting seats 110 are located at both ends of the groove 101 .

[0050] Specifically, a groove 101 is opened on the base 100, and a plurality of spring connecting plates 200 are located inside the groove 101. When the spring connecting plates 200 move, the spring connecting plates 200 are prevented from being affected by external airflow or other substances, thereby ensuring that the spring connecting plates 200 work normally.

[0051] In an optional solution of this embodiment, the base 100 is provided with baffles 150 at both ends of the groove 101 , and a through hole is opened on the baffle 150 , and the tension spring 120 passes through the through hole to be connected to the spring connecting plate 200 .

[0052] Specifically, baffles 150 are disposed on both sides of the base 100 , and the baffles 150 are used to limit the displacement limit position of the spring connecting plate 200 .

[0054] Specifically, the fulcrum seat 520 includes a support seat 521 and a support rod 522. The support rod 522 is fixedly arranged on the support seat 521, and the end of the support rod 522 away from the support seat 521 is arc-shaped. The arc-shaped structure enables the bearing inner ring 600 to smoothly transition from the loading assembly 400 to the fulcrum seat 520.

[0055] Specifically, the height of the bearing inner ring 600 on the fulcrum seat 520 is 0.1 mm higher than the height of the bearing inner ring 600 on the loading assembly 400 .

[0056] In an optional solution of this embodiment, a slot 523 is provided on the support seat 521, and a threaded circular hole matching the slot 523 is provided on the measuring pad 500. The support seat 521 is connected to the measuring pad 500 by bolts so that the fulcrum seat 520 can adjust its position on the measuring pad 500.

[0057] Among them, a slot hole 523 is opened on the support seat 521, and a threaded circular hole is opened on the measuring pad 500. By adjusting the slot hole 523 and the threaded circular hole, the distance between two adjacent slot holes 523 can be changed, and the position of the support rod 522 can be changed to ensure that the support rod 522 can support the inner ring 600 of the bearing.

[0058] In an optional scheme of this embodiment, the rotating assembly 300 includes a bracket 310, a beam 320, a lifting cylinder 330, a rotating cylinder 340 and a positioning core 350; brackets 310 are provided at both ends of the beam 320, the lifting cylinder 330 is provided on the beam 320, the rotating cylinder 340 is connected to the lifting cylinder 330, and the positioning core 350 is connected to the rotating cylinder 340.

[0060] Specifically, when it is necessary to rotate the inner ring of the bearing 450, the lifting cylinder 330 will drive the mounting plate 360 ​​to descend, thereby driving the rotating cylinder 340 set on the mounting plate 360 ​​to descend, and the positioning core 350 set at the lower end of the rotating cylinder 340 will be engaged with the bearing inner ring 600, and then the rotating cylinder 340 drives the positioning core 350 to rotate.

[0061] In an optional scheme of this embodiment, the loading assembly 400 includes a guide rail 410, a pushing cylinder 420 and a push plate 430; the guide rail 410 is located on the base 100, the push plate 430 is located on the guide rail 410, and the push plate 430 is connected to the pushing cylinder 420; a bearing inner ring positioning core 440 is provided at one end of the push plate 430 facing the measuring pad 500, and a rotating bearing 450 is provided on the side of the push plate 430 located on the bearing inner ring positioning core 440 away from the measuring pad 500.

[0062] The size of the bearing inner ring positioning core 440 is smaller than the size of the bearing inner ring 600 .

[0063] When the rotating cylinder 340 drives the bearing inner ring 600 to rotate, the rotating bearing 450 disposed on the push plate 430 will rotate in coordination with the bearing inner ring 600 to prevent the bearing inner ring 600 from bouncing during rotation and affecting the accuracy and stability of the measurement data.

[0064] When the rotary cylinder 340 drives the bearing inner ring 600 to rotate, the power source 130 drives the spring connecting plate 200 to move, so that the measuring contact 210 can measure the bearing inner ring 600 again.

[0065] In an optional solution of this embodiment, the spring connecting plate 200 has no contact with the base 100 .
