[0024] As a technical optimization of this utility model, by setting a limiting mechanism 8, the limiting ring 82 can limit the measuring rod 6, and the spring 83 can limit the movement of the measuring rod 6. When the connecting plate 81 moves to the top of the center of the bearing, the connecting plate 81 is rotated to place the connecting plate 81 inside the bearing so that the user can observe the measuring rod 6.

[0025] refer to Figure 2 A double-ended lead screw 9 is movably connected to the right side of the inner wall of the through groove 71 via a bearing. The other end of the double-ended lead screw 9 passes through the movable plate 73 and the worktable 2 in sequence and is fixedly connected to a knob 10.

[0033] The working principle and usage process of this utility model are as follows: When measuring a bearing, first place the bearing on the top of the workbench 2. Then, rotate the knob 10 to drive the double-acting lead screw 9 to rotate. The rotation of the double-acting lead screw 9 can drive the movable plate 73 and the clamping plate 4 to move closer to the bearing. When the inner side of the clamping plate 4 is in contact with both sides of the bearing surface, observe the position of the measuring scale 3 pointed to by the indicator plate 5 to facilitate the user's recording of the bearing's outer diameter. Then, pull the connecting plate 81 to the top of the bearing center. At this time, the measuring rod 6 and the limiting ring 82 move inward to compress the spring 83. Then, through 180... Rotate the connecting plate 81 ten degrees to place it inside the bearing, then release the connecting plate 81. This causes the spring 83 to rebound and move the measuring rod 6 and the connecting plate 81 outward, allowing the outer side of the connecting plate 81 to press against the inner ring surface of the bearing. At this time, the user can record the distance between the inner and outer rings of the bearing by observing the values ​​on the surfaces of the two measuring rods 6. This allows the user to judge whether the standard is met. Bearings that pass the test can be placed inside the first collection box 15 for storage, while bearings that fail the test can be placed inside the second collection box 16 for recycling.

[0034] In summary, this bearing machining and measuring device, by setting up a clamping plate 4, an indicator plate 5, and a measuring rod 6, allows the clamping plate 4 to move, which in turn moves the indicator plate 5. By observing the position of the indicator plate 5 pointing to the measuring rod 3, the user can easily record the outer diameter of the bearing. At the same time, the clamping plate 4 moves the measuring rod 6, which allows the user to record the inner diameter of the bearing. This solves the problem that existing measuring devices, such as micrometers and vernier calipers, mainly measure the outer diameter of the bearing and obtain dimensional data through contact measurement, but cannot accurately determine whether the inner diameter of the bearing meets the standard, and still require the use of an inner diameter measuring tool, which is quite cumbersome.
