Description

Technical Field

[0001] The utility model belongs to the technical field of detection, and particularly relates to a mechanical lifting type multi-section bearing outer diameter measuring device. Background Technique

[0002] As a high-precision component, the inner diameter and outer diameter of a bearing are all important technical parameters. When measuring the outer diameter of a bearing, it is generally carried out manually offline through measuring tools such as micrometers, and only one section can be measured at a time. If multiple sections need to be measured, multiple adjustments are required and manual calculations are needed to determine whether it is qualified. Manual measurement has low efficiency and the measurement results often have human errors, resulting in low accuracy of the measurement results. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to solve the problem that in the prior art, it is generally carried out manually offline through measuring tools such as micrometers, and only one section can be measured at a time, with low manual measurement efficiency and often human errors in the measurement results, resulting in low accuracy of the measurement results. Now, a mechanical lifting type multi-section bearing outer diameter measuring device is provided.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme: a mechanical lifting type multi-section bearing outer diameter measuring device, including a base, and the base is provided with:

[0005] A clamping mechanism, including an upper pressing head and a lower pressing head distributed up and down, a clamping space for clamping the bearing is formed between the two, and the upper pressing head and the lower pressing head clamp the bearing between the two to fix it;

[0006] A rotating mechanism, whose output end is connected to the upper pressing head, is used to drive the bearing clamped between the upper pressing head and the lower pressing head to rotate. When the rotating mechanism drives the upper pressing head to rotate, the upper pressing head drives the lower pressing head and the bearing to rotate synchronously through the friction force between it and the bearing and the friction force between the bearing and the lower pressing head;

[0007] A first lifting mechanism, whose output end is connected to the rotating mechanism, is used to drive the rotating mechanism and the upper pressing head to lift synchronously;

[0008] A second lifting mechanism, whose output end is connected to the lower pressing head, is used to drive the lower pressing head to lift;

[0009] And a measuring mechanism, including two relatively arranged laser measuring instruments located outside the bearing.

[0010] During detection, place the bearing on the lower pressing head, and drive the upper pressing head to press down through the first lifting mechanism to press the bearing between it and the lower pressing head. The rotating mechanism drives the upper pressing head, the lower pressing head, and the bearing located between the two to rotate synchronously. Measure within the horizontal straight-line range of the laser measuring instrument. During the measurement process, select the data of the entire cross-section of the bearing, collect data through the equipment, calculate the data to determine the size, and lift the bearing up and down through the first lifting mechanism and the second lifting mechanism to measure the outer diameter of the bearing cross-section at different heights. After the measurement is completed, the first lifting mechanism drives the upper pressing head to move upward, and the bearing is unloaded by its own weight. If it is unqualified, it will be automatically removed.

[0011] The above technical solution uses the upper pressing head and the lower pressing head to fix the bearing and then drives the whole to rotate by the rotating mechanism, and uses the first lifting mechanism and the second lifting mechanism to lift and lower the bearing. During the lifting and lowering process of the bearing, the laser measuring instrument can measure the outer diameter of its cross-section at different heights, realizing the measurement of the outer diameter of multiple cross-sections of the bearing and improving the detection efficiency.

[0012] Further, a positioning plate is connected to the output end of the second lifting mechanism, and the lower pressing head is rotatably connected to the positioning plate; when the rotating mechanism drives the upper pressing head, the lower pressing head, and the bearing clamped between the two to rotate synchronously, relative rotation occurs between the lower pressing head and the positioning plate, and a rolling bearing is provided between the two.

[0013] Further, one end of the positioning plate is connected to the output end of the second lifting mechanism, and a positioning rod is inserted through the other end. The positioning plate is provided with a through hole for the positioning rod to pass through, and the positioning rod is slidably connected to the positioning plate through the through hole to guide the lifting of the positioning plate. The lower pressing head is located between the second lifting mechanism and the positioning rod.

[0014] Further, a positioning head for extending into the bearing is protruded from the bottom of the upper pressing head, and there is a clearance fit between the positioning head and the inner ring of the bearing. When the first lifting mechanism drives the upper pressing head to press down, the positioning head first extends into the bearing for positioning, and then the upper pressing head presses the bearing to fix it.

[0015] Further, both the first lifting mechanism and the second lifting mechanism are screw-nut mechanisms.

[0016] Further, a slide rail is installed on the base, and a slider cooperating with the slide rail is provided on the rotating mechanism. The slide rail is slidably connected to the slider to guide the lifting of the rotating mechanism and the upper pressing head.

[0017] The beneficial effects of the present utility model are as follows: The present utility model uses the upper pressing head and the lower pressing head to fix the bearing and then drives the whole to rotate by the rotating mechanism, and uses the first lifting mechanism and the second lifting mechanism to lift and lower the bearing. During the lifting and lowering process of the bearing, the measuring instrument can measure the outer diameter of its cross-section at different heights, realizing the measurement of the outer diameter of multiple cross-sections of the bearing and improving the detection efficiency.

The spindle motor is fixed on the upper mounting base 13, and there is a spindle connected between the output end of the spindle motor and the upper pressing head 201.

The output end of the second lifting mechanism 5 is connected to a positioning plate 7, and the lower pressing head 202 is rotatably connected to the positioning plate 7. When the rotating mechanism 3 drives the upper pressing head 201, the lower pressing head 202 and the bearing 17 clamped between the two to rotate synchronously, relative rotation occurs between the lower pressing head 202 and the positioning plate 7, and a rolling bearing is provided between the two.

If it is unqualified, it will be automatically removed.
