Description

Technical Field

[0001] This utility model relates to the field of bearing production and testing technology, specifically a roundness testing device for roller bearings. Background Technology

[0002] Roller bearings are extremely important rotating connection components in modern mechanical equipment. They provide a high degree of sealing and are also the core component that allows two mechanical entities to rotate and connect with each other. Their main structure consists of an inner grooved ring, an outer grooved ring, and rollers. The roundness of the grooved rings directly affects the assembly of the bearing and its actual working performance. Therefore, the roundness inspection of the inner and outer rings of roller bearings is crucial during the production process.

[0003] Most existing roller bearing roundness testing equipment is designed for testing the bearing as a whole. However, the roundness testing of the inner and outer rings during the production process is mostly done manually using tools, resulting in low automation, low efficiency, and insufficient accuracy. This indirectly increases the workload for roundness testing of the bearing after assembly.

[0004] To address the aforementioned issues, we propose an improvement: a roundness testing device for roller bearings. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

Support blocks are slidably installed at both ends inside the adjustment box. A motor is arranged above the adjustment box. The adjustment box is connected to the rotating shaft of the motor. A laser rangefinder is arranged on the right side of the receiving groove. The height of the laser rangefinder is higher than that of the receiving groove.

[0007] As a preferred technical solution of this utility model, a column is fixedly installed on the left end of the top surface of the operating table by bolts, a hanger is fixedly installed on the top right side of the column by bolts, a sleeve is fixedly installed on the bottom right end of the hanger by connection, a bearing is fixedly installed on the bottom surface of the sleeve by screws, and the center of the top surface of the adjusting box is fixedly connected to the bottom surface of the inner ring of the bearing by screws.

[0008] As a preferred embodiment of this utility model, the bottom of the motor is fixedly connected to the right end of the top surface of the hanger by bolts, and a rotating shaft is rotatably installed at the center of the top surface of the inner wall of the sleeve, and the top of the rotating shaft is coaxially fixedly connected to the rotating shaft of the motor.

[0009] As a preferred technical solution of this utility model, the bottom end of the rotating shaft passes through the sleeve and the bearing and is fixedly connected to the center of the top surface of the adjusting box. A bidirectional threaded rod is rotatably installed inside the adjusting box. The reverse thread lengths at the left and right ends of the bidirectional threaded rod are equal. A handwheel is rotatably installed on the right side of the outside of the adjusting box. The rotating shaft of the handwheel is coaxially fixedly connected to the bidirectional threaded rod.

[0010] As a preferred technical solution of this utility model, the bidirectional threaded rod passes through two support blocks and is threadedly connected to them. The opposite sides of the bottom ends of the two support blocks are both arc surfaces, and protrusions are fixedly provided at the bottom of the opposite sides of the two support blocks.

[0011] As a preferred technical solution of this utility model, a guide rail is fixedly installed at the front end of the bottom surface of the receiving groove, a slider is slidably installed on the surface of the guide rail, a vertical plate is fixedly installed at the front end of the top of the slider, a nylon brush is fixedly installed at the top of the front of the vertical plate, the height of the nylon brush is the same as the bottom height of the support block, a spring telescopic rod is fixedly installed in the middle of the back of the vertical plate, and the rear end of the spring telescopic rod is fixedly connected to the inner wall of the receiving groove by bolts.

[0013] The beneficial effects of this utility model are as follows: This roundness detection device for roller bearings performs roundness detection by fixing the roller bearing ring from the inner ring, suspending it, and rotating it. Compared with detecting by rotating it in the groove using a probe, this method of suspension and detection using an infrared laser rangefinder is more accurate. Furthermore, it is equipped with a nylon brush, which can pre-clean the detection surface of the bearing ring during detection, preventing the surface from being covered with debris such as paper scraps and foam, which would affect the detection results and improve the quality of roundness detection.

[0021] A column 2 is fixedly installed on the left end of the top surface of the control panel 1 by bolts. A hanger 3 is fixedly installed on the top right side of the column 2 by bolts. A sleeve 4 is fixedly installed on the bottom right end of the hanger 3 by connection. A bearing 5 is fixedly installed on the bottom outside the sleeve 4 by screws. The center of the top surface of the adjustment box 6 is fixedly connected to the bottom surface of the inner ring of the bearing 5 by screws.

[0022] The bottom of the motor 7 is fixedly connected to the right end of the top surface of the hanger 3 by bolts. A rotating shaft 8 is rotatably installed at the center of the top surface of the inner wall of the sleeve 4. The top of the rotating shaft 8 is coaxially fixedly connected to the rotating shaft of the motor 7.

[0023] The bottom end of the rotating shaft 8 passes through the sleeve 4 and the bearing 5 and is fixedly connected to the center of the top surface of the adjusting box 6. A bidirectional threaded rod 9 is rotatably installed inside the adjusting box 6. The reverse thread lengths at the left and right ends of the bidirectional threaded rod 9 are equal. A handwheel 10 is rotatably installed on the right side of the outside of the adjusting box 6. The rotating shaft of the handwheel 10 is coaxially fixedly connected to the bidirectional threaded rod 9.

[0024] The bidirectional threaded rod 9 passes through the two support blocks 11 and is threadedly connected to them. The opposite sides of the bottom of the two support blocks 11 are both arc surfaces, and protrusions are fixedly provided at the bottom of the opposite sides of the two support blocks 11.

[0025] A guide rail 13 is fixedly installed at the front end of the bottom surface inside the receiving groove 12. A slider 14 is slidably installed on the surface of the guide rail 13. A vertical plate 15 is fixedly installed at the front end of the top of the slider 14. A nylon brush 16 is fixedly installed on the top of the front of the vertical plate 15.

[0027] Working principle: In use, this roundness detection device for roller bearings aligns the center of the bearing to be tested with two support blocks 11 and secures them. Turning the handwheel 10 drives the bidirectional threaded rod 9 to rotate, causing the two support blocks 11 to move away from each other until they support and fix the inner side of the bearing to be tested. Then, the slider 14 mounted on the vertical plate 15 is moved until the nylon brush 16, under the action of the spring telescopic rod 17, presses against the side surface of the bearing to be tested. The motor 7 and laser rangefinder 18 are then activated. The motor 7 drives the rotating shaft 8 to rotate, which in turn causes the adjusting box 6 and its support blocks 11 to rotate under the action of the bearing 5. The bearing to be tested rotates synchronously. The nylon brush 16 cleans the surface deposits as the bearing rotates, while the laser rangefinder 18 measures the distance changes to obtain more accurate roundness data.
