AI Technical Summary
Existing internal diameter measuring instruments cannot quickly measure the bearing's internal diameter, nor can they simultaneously measure whether the bearing surface is flat, resulting in a single measurement method.
Using optical principles, the light distribution is captured by a photosensitive plate and sensor array. Combined with photoelectric sensors and a size measurement module, the bearing inner diameter and surface flatness are measured simultaneously.
It enables rapid and accurate measurement of bearing inner diameter and can intuitively display the surface flatness, thus improving the overall measurement effect.

[0028] like Figures 1-5 As shown, this embodiment proposes a bearing quality inspection inner diameter measuring instrument, including an inner diameter measuring platform 1. The upper end of the inner diameter measuring platform 1 is provided with a lamp wire sensing frame 2, the lower end of the lamp wire sensing frame 2 is provided with a light sensing plate 3, the vertical mapping surface of the light sensing plate 3 is provided with a light-illuminating plate 4, both ends of the light-illuminating plate 4 are provided with sliding grooves 6, the inner end of the sliding groove 6 is provided with a slider 5 and a positioning spring 7, the outer end of the slider 5 is provided with an arc-shaped plate, the right-angle end of the inner diameter measuring platform 1 is provided with a right-angle measuring ruler 8, and the bearing is wrapped between the right-angle measuring ruler 8 and the arc-shaped plate.
[0029] The light-emitting plate 4 is used to guide light to pass accurately through the inner ring of the bearing, the light-sensing plate 3 is used to receive the light passing through the inner diameter of the bearing and measure the light intensity distribution, and the arc plate and the right-angle measuring ruler 8 are used to fix the bearing position.
[0030] The surface of the light sensing plate 3 is covered with a sensor array for capturing the light distribution.
[0031] The photoelectric sensor integrated inside the light sensing plate 3 has its external end signal connected to the light display module.
[0032] The light display module is connected to the size calculation module.
[0033] The lower end of the arc-shaped plate is fixedly connected with the sliding block 5, which slides along the sliding groove 6, and the sliding block 5 and the sliding groove 6 are elastically connected through the positioning spring 7.
[0034] The inner diameter measuring table 1 provides a stable base platform.
[0035] The light line sensing frame 2 carries the light sensing plate 3 and the light source, ensuring accurate alignment.
[0036] The light sensing plate 3 is responsible for receiving light through the bearing inner diameter and measuring the light intensity distribution.
[0037] The light plate 4 guides the light to accurately pass through the bearing inner ring.
[0038] The sliding groove 6, sliding block 5 and positioning spring 7 adjust the position of the arc-shaped plate to adapt to bearings of different sizes.

This step requires the participation of the light sensing plate 3 under the light line sensing frame 2 to perform preliminary light path correction.
[0044] Light penetration and capture: after the light successfully penetrates the inner ring of the bearing, it will directly hit the light sensing plate 3.
