AI Technical Summary
In the existing bearing inner hole grinding equipment, the measuring arm fine adjustment mechanism has a complex structure, high processing difficulty, high cost, and it is difficult to achieve micro-adjustment to maintain stable clamping, resulting in unstable measurement.
A bearing inner hole grinder measuring arm fine-tuning mechanism is designed, and a combined structure of sensor, sensing foot, measuring arm and measuring claw is adopted. By setting a release groove and threaded hole on the measuring arm, and connecting the first adjustment screw and the second adjustment screw, the opening size adjustment of the measuring claw is achieved.
This design simplifies the processing process, reduces costs, improves measurement stability, and can control the measurement dimensions of the bearing inner bore grinding diameter to ≤0.003mm.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing processing, in particular to a fine adjustment mechanism for a measuring arm of a bearing inner hole grinding machine. Background Art
[0002] The measuring claws on the on-line measuring sensor for the inner hole grinding of conventional miniature bearings are installed on a dovetail fine adjustment main body, which has a complex structure, high processing difficulty and high cost. The key lies in that it is necessary to achieve the purpose of micro adjustment and ensure that the fine adjustment main body cannot be loose during clamping, which is difficult to achieve. Therefore, the fine adjustment main body is in a slightly loose state during adjustment, resulting in instability of the measuring claws during grinding measurement. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a fine adjustment mechanism for a measuring arm of a bearing inner hole grinding machine aiming at the above-mentioned deficiencies of the prior art.
[0004] To solve the above technical problem, the technical scheme adopted by the utility model is:
[0005] A fine adjustment mechanism for a measuring arm of a bearing inner hole grinding machine includes a sensor, an induction foot is arranged on the sensor, a measuring arm is connected to the induction foot, a measuring claw is installed on the measuring arm, a release groove is formed on the measuring arm, a first threaded hole and a second threaded hole are sequentially machined on the release groove, the first threaded hole completely penetrates the release groove, the second threaded hole is located above the release groove, a first adjusting screw is connected to the first threaded hole, and a second adjusting screw is connected to the second threaded hole.
[0006] Further, the release groove is obliquely arranged.
[0007] Further, the first adjusting screw is a round head screw, and the second adjusting screw is a set screw.
[0008] Compared with the prior art, the fine adjustment mechanism for a measuring arm of a bearing inner hole grinding machine of the utility model is convenient to process, low in cost, easy to debug, and stable and convenient in measurement. Description of the Drawings

[0010] Wherein, 1. Sensor, 2. Threaded mounting handle, 3. Induction foot, 4. Measuring arm, 5. Measuring claw, 6. Release groove, 7. First adjusting screw, 8. Second adjusting screw. Detailed Embodiment
[0011] The technical solutions in the embodiments of the utility model will be clearly and completely described below.
[0012] Such as Figure 1As shown in the figure, a fine-tuning mechanism for a measuring arm of a bearing inner hole grinding machine includes a sensor 1. On one side of the sensor 1, there is a threaded mounting handle 2, and on the other side, there is an induction foot 3. A measuring arm 4 is connected to the induction foot 3. The measuring arm 4 is fixed to the induction foot 3 by a mounting screw 1. A measuring claw 5 is mounted on the measuring arm 4, and the measuring claw 5 is fixed to the measuring arm 4 by a mounting screw 2. A release groove 6 is provided on the measuring arm 4. A first threaded hole and a second threaded hole are successively machined on the release groove 6. The first threaded hole completely penetrates the release groove 6, and the second threaded hole is located above the release groove 6. A first adjusting screw 7 is connected to the first threaded hole, and a second adjusting screw 8 is connected to the second threaded hole.
[0013] In this embodiment, the release groove 6 is machined obliquely downward. A first threaded hole and a second threaded hole are successively machined on the release groove 6. The first threaded hole vertically penetrates the release groove 6, and the second threaded hole is vertically arranged above the release groove 6. The first adjusting screw 7 is a round head screw, and the second adjusting screw 8 is a set screw.
[0014] During adjustment, first tighten the set screw, then tighten the round head screw, separate the set screw from the bottom of the release groove 6, and then tighten the round head screw. At this time, the measuring claw opens. Screw the set screw into the second threaded hole and tighten the set screw to press against the bottom of the release groove 6. Then tighten the round head screw again. At this time, the measuring claw closes. By this method, the opening size of the measuring claw is adjusted. During the measurement process, adjust the opening of the measuring claw to the nominal size of the bearing inner hole. After adopting the fine-tuning mechanism of the measuring arm of the present invention, the measured size of the grinding diameter of the bearing inner hole can be controlled within ≤0.003 mm.
[0015] The present invention is not limited to the described embodiments. Those skilled in the art can still make some corrections or changes without departing from the spirit and the disclosed scope of the present invention. Therefore, the scope of the protection of the rights of the present invention shall be subject to the scope defined by the claims.
