Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing testing technology, and in particular to a clamping fixture for testing the outer ring of a bearing. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Therefore, a clamping device for inspecting bearing outer rings is needed to solve this problem.
[0003] A patent website discloses a clamping device for testing bearing outer rings (publication number: CN 218443589U), including a base, a side plate on one side of the upper surface of the base, a top plate on the upper surface of the side plate, a T-shaped rod slidably connected inside the top plate, and an annular plate on the outer side of the T-shaped rod and above the top plate. This utility model has a simple structure and can remove or clamp the bearing outer ring by lifting or pressing down the T-shaped rod, thereby reducing the time for workers to clamp or remove the bearing outer ring and improving the testing efficiency of the bearing outer ring. It can also use the spring force to make the pressure roller assist in clamping the bearing outer ring, which makes it easier for workers to adjust the dial indicator and the limiting plate. It can also rotate the first handwheel according to the size of the bearing outer ring, so that the screw drives the limiting plate and the sliding rod to move to a suitable position to limit the bearing outer ring.
[0004] The above technology uses a pressure roller and two support rollers to clamp and position the outer ring of the bearing. Then, a second handwheel drives one of the support rollers to rotate, allowing the outer ring of the bearing to rotate in conjunction with a dial indicator for testing. However, during use, the first handwheel needs to be pressed down to make the pressure roller press against the outer ring of the bearing, which makes the testing inconvenient. Furthermore, it cannot guarantee the stability of the rotation of the outer ring of the bearing, thus affecting the accuracy of the test. Therefore, there is room for improvement. Utility Model Content
[0005] This invention provides a clamping fixture for inspecting the outer ring of a bearing, in order to solve the problems mentioned in the background art.
[0006] To address the aforementioned problems, this utility model provides a clamping fixture for testing the outer ring of a bearing, comprising a mounting plate, a support wheel, a movable wheel, and a drive wheel. The mounting plate is installed in the testing equipment. A groove is formed in the mounting plate. The support wheel is rotatably mounted in the mounting plate and located on one side of the groove. A first slider is slidably connected within the groove, and a first electric telescopic rod is connected to the rear side of the first slider. The first electric telescopic rod is installed on the rear side of the mounting plate. The movable wheel is rotatably connected in the slider and matches the support wheel. A second slider is slidably connected within the groove, and a second electric telescopic rod is connected to the rear side of the second slider. The second electric telescopic rod is installed on the rear side of the mounting plate. The drive wheel is rotatably located in the second slider and is located on the front side of the mounting plate. A motor is mounted at the rear end of the second slider, and the output shaft of the motor rotatably passes through the second slider and is connected to the drive wheel.
[0007] Preferably, two guide rods are symmetrically arranged inside the groove, and the upper and lower sides of the first slider and the second slider are slidably connected to the guide rods.
[0008] Preferably, a convex ring is fixedly provided in the middle of the support wheel and the movable wheel, and the convex ring is embedded in the raceway inside the outer ring of the bearing.
[0009] Preferably, a rubber drive ring is fitted onto the outer surface of the drive wheel.
[0010] The beneficial effects of adopting the above technical solutions are:
[0011] 1. When in use, place the outer ring of the bearing on the support wheel and the movable wheel, and drive the first slider to move through the first telescopic rod, thereby clamping the outer ring of the bearing from the inside, making clamping and positioning more convenient, and at the same time making the convex ring embedded in the raceway of the outer ring of the bearing, ensuring the stability of the clamping and positioning of the outer ring of the bearing.
[0012] 2. The second slider is driven by the second telescopic rod to move within the groove, causing the drive wheel to contact the outer ring of the bearing. The operation of the motor causes the drive wheel to rotate, which in turn causes the outer ring of the bearing to rotate through friction of the drive ring. This, in turn, cooperates with the testing equipment to perform testing operations. Since the convex rings in the support wheel and the movable wheel are embedded in the raceway of the outer ring of the bearing, the stability of the rotation of the outer ring of the bearing is ensured, thereby improving the accuracy of the testing.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] like Figure 1-4In this embodiment, a clamping fixture for testing the outer ring of a bearing includes a mounting plate 1, a support wheel 2, a movable wheel 3, and a drive wheel 4. The mounting plate 1 is installed in the testing equipment. A groove 11 is formed in the mounting plate 1. The support wheel 2 is rotatably installed in the mounting plate 1 and is located on one side of the groove 11. A first slider 31 is slidably connected in the groove 11, and a first electric telescopic rod 32 is connected to the rear side of the first slider 31. The first electric telescopic rod 32 is installed on the rear side of the mounting plate 1. The movable wheel 3 is rotatably connected in the first slider 31 and matches the support wheel 2. A second slider 41 is slidably connected in the groove 11, and a second electric telescopic rod 42 is connected to the rear side of the second slider 41. The second electric telescopic rod 42 is installed on the rear side of the mounting plate 1. The drive wheel 4 is rotatably disposed in the second slider 41 and is located on the front side of the mounting plate 1. A motor 43 is installed at the rear end of the second slider 41, and the output shaft of the motor 43 rotatably passes through the second slider 41 and is connected to the drive wheel 4.
[0022] With the above technical solution, the bearing outer ring 6 is fitted onto the support wheel 2 and the movable wheel 3. The first electric telescopic rod 32 drives the first slider 31 to move within the slide groove 11, thereby causing the movable wheel 3 to move. The movement of the movable wheel 3, in conjunction with the support wheel 2, clamps the bearing outer ring 6 from the inside. At this time, the second electric telescopic rod 42 drives the second slider 41 to move within the slide groove 11, causing the drive wheel 4 to abut against the outer surface of the bearing outer ring 6. The motor 43 then drives the drive wheel 4 to rotate, thereby driving the bearing ring 6 to rotate within the support wheel 2 and the movable wheel 3. This allows the testing equipment to perform testing on the bearing outer ring 6.
[0023] Preferably, two guide rods 12 are symmetrically arranged inside the slide groove 11, and the upper and lower sides of the first slider 31 and the second slider 41 are slidably connected to the guide rods 12.
[0024] Through the above technical solution, the two guide rods 12 are used to ensure the stability of the first slider 31 and the second slider 41 in the slide groove 11. At the same time, since the upper and lower sides of the first slider 31 and the second slider 41 are connected to the guide rods 12, the motor 43 can stably drive the drive wheel 4 to rotate.
[0025] Preferably, a convex ring 5 is fixedly provided in the middle of the support wheel 2 and the movable wheel 3, and the convex ring 5 is embedded in the raceway inside the outer ring 6 of the bearing.
[0026] Through the above technical solution, the convex ring 5 is embedded in the raceway inside the outer ring 6 of the bearing, so that after the outer ring 6 of the bearing is stably clamped, it can maintain stable rotation under the action of the drive wheel 4.
[0027] Preferably, a rubber drive ring 44 is fitted onto the outer surface of the drive wheel 4.
[0028] Through the above technical solution, the driving ring 44 is designed to avoid rigid contact between the driving wheel 4 and the outer ring 6 of the bearing, thereby preventing wear on the outer ring 6 of the bearing.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
