Description

Technical Field

[0001] The utility model relates to the technical field of bearing measurement, in particular to a bearing outer diameter dimension measuring mechanism. Background Art

[0002] Each parameter of the bearing needs to be within the qualified range, otherwise the bearing will affect its assembly accuracy when in use, thereby affecting the operation of the machine using the bearing. Therefore, in the bearing production process, it is necessary to measure the various dimensions of the bearing to ensure that the various dimensions of the bearing are qualified. If a finished bearing needs to know its various dimensions, it is necessary to manually place the workpiece on the measuring table, manually measure one dimension, and then place it on another gauge to measure the outer diameter and outer end height of the bearing. At present, the various dimensions of the finished bearing are measured using the corresponding manual measuring table. The measurement of the same bearing requires switching to use several different devices and manual operation. The process is complicated and cumbersome, and the efficiency is not high.

[0003] In order to solve the above problems, we urgently need a bearing outer diameter dimension measuring mechanism. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a bearing outer diameter dimension measuring mechanism to solve the problem mentioned in the above background technology that the various dimensions of the finished bearings are currently measured using a corresponding manual measuring table. The measurement of the same bearing requires switching to use several different devices and manual operation, which makes the process complicated and cumbersome and inefficient.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing outer diameter dimension measuring mechanism, including a main frame, characterized in that: a slide rail is fixedly installed on the front outer surface of the main frame, a sliding plate is slidably arranged on the outer surface of the slide rail, a carrier plate is fixedly installed on the front outer surface of the sliding plate, outer diameter measuring rods are arranged on the left and right sides of the carrier plate, a stepper motor is fixedly installed on the front side of the carrier plate, a roller is arranged on the output end of the stepper motor, a cylinder is fixedly installed on the top of the main frame, and a fixed seat is fixedly installed on the lower outer surface of the main frame.

[0006] Preferably, the lower end horizontal lines of the two groups of outer diameter measurements are located on the same X-axis line as the measured bearings.

[0007] By adopting the above technical solution, by setting the lower end horizontal lines of two sets of outer diameter measurements and the measured bearings on the same X-axis line, the outer diameter of the bearing is measured with higher accuracy.

[0008] Preferably, the outer surface of the roller is movably fitted with the upper outer surface of the measured bearing, and the roller is made of soft rubber material.

[0009] By adopting the above technical solution, the outer surface of the roller is arranged to fit movably with the upper outer surface of the measured bearing, so that the bearing can be rotated and rolled during measurement, so that the measurement data is more accurate. The roller is made of soft rubber material, which greatly increases the friction of the outer surface of the roller and facilitates rolling measurement.

[0010] Preferably, the lower end of the cylinder passes through the front outer surface of the main frame, and the lower end of the cylinder is fixedly connected to the rear side of the sliding plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0017] Please refer to Figure 1-2When using the utility model, in order to solve the problem that the current measurement of various dimensions of finished bearings uses a corresponding manual measuring table, the measurement of the same bearing requires switching to use several different devices, and the manual operation is complicated and cumbersome, and the efficiency is low. A slide rail 2 is fixedly installed on the front outer surface of the main frame 1, and a sliding plate 8 is slidably arranged on the outer surface of the slide rail 2. A carrier plate 3 is fixedly installed on the front outer surface of the sliding plate 8. Outer diameter measuring rods 7 are arranged on the left and right sides of the carrier plate 3.

[0018] Working principle: When using the bearing outer diameter measuring mechanism, place the workpiece to be measured on the measuring station, start the cylinder 4, and drive the sliding plate 8 to move downward along the slide rail 2. The downward movement of the sliding plate 8 will drive the carrier plate 3 to move downward until the roller 6 under the carrier plate 3 is movably fitted with the upper outer surface of the measured bearing. The cylinder 4 stops running, and the stepper motor 5 starts to drive the roller 6 to rotate. The two sets of outer diameter measuring rods 7 are also started.
