[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0016] Please refer to Figure 1-2, a measuring mechanism for the inner diameter drop of the outer ring of a bearing of the present utility model, comprising: a base plate 1, a vertical plate 2 provided on the base plate, a linear slide rail 3 provided on the vertical plate, a slideway connecting plate 4 fixedly connected to the slider on the linear slide rail, a micrometer measuring instrument 5 connected to the slideway connecting plate, a measuring rod fixing sleeve 6 with one end connected to the slideway connecting plate, a bearing seat 7 provided on the vertical plate for placing the bearing to be tested, and a product pressing mechanism for pressing the bearing to be tested. Among them, the vertical plate is inclined on the base plate at an angle of 8-12 degrees, preferably 10 degrees, which is convenient for inspecting and installing the bearing to be tested. The micrometer measuring instrument is fixed on the micrometer measuring fixing block 8 and connected to the slideway connecting block. The slideway connecting block and the linear slide rail are fixed together, which is convenient for adjusting the measuring height up and down. When inspecting, it can move up and down smoothly and the measuring data is accurate.
[0017] Specifically, the other end of the measuring rod fixing sleeve penetrates the vertical plate and is rotatably connected to a measuring rod 18 through a pin shaft 9. The two ends of the measuring rod extend outside the measuring rod fixing sleeve and rotate up and down with the pin shaft as the fulcrum. On the front end face of the measuring rod fixing sleeve, there is a first measuring terminal 10 that fits against the inner cavity wall of the bearing to be tested. In order to make the first measuring terminal closely fit against the inner cavity wall of the bearing to be tested, a third elastic member 11 is provided between the front end face of the linear slide rail and the measuring rod fixing sleeve, which plays a role of applying pressure by elastic support. At this time, the inner diameter value of the bearing at the current first measuring terminal will be displayed on the micrometer measuring instrument.
[0018] Specifically, the front end of the measuring rod extends into the bearing 12 to be tested and is provided with a second measuring terminal 13. Among them, the first measuring terminal and the second measuring terminal are coaxially arranged in parallel. A first elastic member 14 is provided between the measuring rod fixing sleeve and the measuring rod, which is used to keep the front end of the measuring rod in a raised state and always fit against the inner cavity wall of the bearing to be tested. When an employee inspects, slightly press down the bearing to be tested with force so that the outer diameter of the bearing fully fits on the bearing seat, and the bearing product to be tested can be slowly rotated. At this time, the rear end of the measuring rod contacts the detection head of the micrometer measuring instrument when measuring the bearing. The second measuring terminal is tilted upward around the pin shaft and closely fits against the inner cavity wall of the bearing under the action of the measuring rod and the first elastic member, accurately measuring the inner diameter size of the bearing at the second measuring terminal, thereby obtaining the inner diameter drop size of the bearing and judging whether the inner diameter turning drop size of the bearing is qualified.
[0019] Specifically, a "V"-shaped notch for placing the bearing to be tested is provided on the bearing seat. The product pressing mechanism includes a pressing rod 16 rotatably arranged on one side of the vertical plate through a pin 15 and a second elastic member 17 provided between the vertical plate and the pressing rod, which applies a downward pressure to the front end of the pressing rod to fix the bearing to be tested on the bearing seat, facilitating the measurement of the first measuring terminal and the second measuring terminal. Among them, the pressing rod is of an "L" shape, and the first elastic member, the second elastic member, and the third elastic member are springs.
[0020] The beneficial effects of the present utility model are as follows: It can quickly detect the accurate inner diameter drop size of bearings on the production line, and has the advantages of low material positioning requirements, high detection accuracy, fast detection speed, flexible setting of the detection range, and quick switching of detection models, bringing great convenience to production and use.
[0021] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
