Description

Technical Field

[0001] This invention relates to a specialized automated measurement and modification instrument for bearings. Background Technology

[0002] Currently, most bearing assembly instruments use manual reading of torsion spring gauges for data acquisition. These instruments include the D923 series, D913 series, B023 series, and B013 series. The diameter of the torsion spring gauge in these instruments is 28mm. Therefore, during the instrument automation measurement upgrade phase, sensors are needed to replace the torsion spring gauges to achieve automatic data acquisition. However, the diameter of the sensor housing is usually 8mm, which is a significant difference between the two. Summary of the Invention

[0007] The bottom end of the first connecting part is connected to the top end of the sleeve body;

[0008] The bottom end of the limiting collar is located inside the second connecting part. The limiting collar is used to fix the sensor. The main body of the sensor is fixed inside the limiting collar, and the head of the sensor extends to the outside along the axial through hole and the sleeve body.

[0012] Furthermore, the upper inner wall of the sleeve body is provided with internal threads, and the outer wall of the first connecting part is provided with external threads. The sleeve body and the first connecting part are connected by threads.

[0020] Combination Figures 1 to 3 This embodiment describes a sensor conversion sleeve, which includes a sleeve body 1, a sleeve rotating cap 2, a fine-tuning structure 3, a limiting collar 4, and a locking mechanism 5.

[0021] The sleeve body 1 is a hollow columnar structure, and the lower outer diameter of the sleeve body 1 is the same as the diameter of the torsion spring gauge cylinder; and a first opening groove 6 is provided on the upper side wall of the sleeve body 1.

[0022] The fine-tuning structure 3 includes a first connecting part 3-1, a rotating part 3-2, a buffer part 3-3, and a second connecting part 3-4; the first connecting part 3-1, the rotating part 3-2, and the second connecting part 3-4 are all cylindrical structures, the buffer part 3-3 is a cylindrical structure, and the buffer part 3-3 is provided with a central through hole 3-5; at the same time, the first connecting part 3-1, the rotating part 3-2, the buffer part 3-3, and the second connecting part 3-4 are arranged coaxially from bottom to top;

[0023] The bottom end of the first connecting part 3-1 is connected to the top end of the sleeve body 1;

[0024] The bottom end of the limiting collar 4 is located inside the second connecting part 3-4. The limiting collar 4 is used to fix the sensor. The main body of the sensor is fixed inside the limiting collar 4, and the head of the sensor extends to the outside along the axial through hole 3-5 and the sleeve body 1.

[0025] The sleeve rotating cap 2 has a cylindrical structure. The sleeve rotating cap 2 is nested from top to bottom outside the second connecting part 3-4, and the inner wall of the sleeve rotating cap 2 is in close contact with the outer wall of the buffer part 3-3; at the same time, the sensor wire is led out from the top of the sleeve rotating cap 2.

[0026] The locking mechanism 5 is located on one side of the first opening groove 6, so as to achieve a fixed connection between the first connecting part 3-1 and the sleeve body 1 through the locking mechanism 5.

[0027] In this embodiment, the sleeve rotating cap 2 is provided with anti-slip texture to facilitate the rotation of the sleeve rotating cap 2; the setting of the first opening groove 6 makes the locking mechanism 5 have a better locking effect and makes it easier to rotate the fine adjustment structure 3.

[0028] The method of using the sensor conversion sleeve described in this embodiment is as follows:

[0029] First, the sensor body is secured inside the limiting collar, and the sensor head extends outward along the axial through hole and the sleeve body. The sensor tail connection line is led out from the top of the rotating cap. By adjusting the contact position between the sensor and the limiting collar, the position of the sensor inside the sensor conversion sleeve is adjusted. If the position is too far, data cannot be collected. If the position is too close, the effective range of the sensor will be missed, or the sensor may even exceed its range or malfunction.

[0030] Secondly, after adjusting the sensor position, the sleeve body and the sleeve rotating cap are fastened by threaded connection. When the sensor position or force measurement needs to be fine-tuned, it is done by rotating the fine-tuning structure. Before fine-tuning, the locking mechanism needs to be loosened first. The locking mechanism is fastened with an internal hex screw. After loosening the locking mechanism, the contact position of the sensor measuring point inside the sensor conversion sleeve is adjusted within a small range by rotating the fine-tuning structure, thereby achieving fine-tuning of the position and force measurement. After adjustment, the locking mechanism needs to be tightened to avoid position changes caused by misoperation. When using this sensor conversion sleeve, the locking mechanism should always be in the locked state unless necessary adjustments are made.

[0031] Finally, after the sensor is installed in the sensor conversion sleeve and the sensor position is adjusted, the sensor conversion sleeve is applied to the bearing-specific instrument. The diameter of the sleeve body should match the instrument used. Inside the sleeve body, the displacement change of the bearing being measured is transmitted to the sensor measuring point through a transmission mechanism, thereby realizing data acquisition. The transmission mechanism is a spring ring.

[0032] In a preferred embodiment, the lower part of the limiting collar 4 is a cylindrical structure, and the upper part of the limiting collar 4 is a conical structure, which has a mounting through hole; at the same time, a second opening groove 7 is provided at the conical part of the upper part of the limiting collar 4, and the main body of the sensor is stuck in the upper cylindrical mounting through hole of the limiting collar 4; the inner diameter of the mounting through hole is the same as the diameter of the sensor shell.

[0033] In this embodiment, the sensor body is more easily placed inside the limiting collar 4 by setting the second opening groove 7. At the same time, by rotating the sleeve and rotating the cap 2, and by utilizing the conical structure on the upper part of the limiting collar 4, the structure on both sides of the second opening groove 7 can better clamp the sensor body.

[0034] In a preferred embodiment, the upper inner wall of the sleeve body 1 is provided with an internal thread, and the outer wall of the first connecting part 3-1 is provided with an external thread. The sleeve body 1 and the first connecting part 3-1 are connected by the thread.

[0035] In a preferred embodiment, the inner wall of the sleeve rotating cap 2 is provided with an internal thread, and the outer wall of the second connecting part 3-4 is provided with an external thread. The sleeve rotating cap 2 and the second connecting part 3-4 are connected by the thread.

[0036] In a preferred embodiment, the outer diameter of the first connecting part 3-1 is smaller than the outer diameter of the rotating part 3-2, the outer diameter of the second connecting part 3-4 is smaller than the outer diameter of the buffer part 3-3, and the outer diameter of the buffer part 3-3 is smaller than the outer diameter of the rotating part 3-2.

[0037] In this embodiment, the outer wall of the rotating part 3-2 is provided with anti-slip texture, and the above-mentioned arrangement makes it more convenient to rotate the fine-tuning structure 3.

[0038] In a preferred embodiment, the locking mechanism 5 of this embodiment is an internal hexagon screw; the internal hexagon screw is threaded on one side of the first opening groove 6 of the sleeve body 1, and by tightening the internal hexagon screw, the front end of the internal hexagon screw touches the outer wall of the first connecting part 3-1, thereby realizing the fixed connection between the first connecting part 3-1 and the sleeve body 1.

[0039] In this embodiment, a groove is provided at the locking mechanism 5 of the sleeve body 1 to facilitate the tightening of the internal hexagon screw.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
