Generally, the inner and outer ring edges of roller bearings are provided with ribs, and the roller can be limited between the inner and outer rings through the ribs. In order to avoid the ribs affecting the rotation of the rollers, the side of the rib close to the roller is set as an inclined surface. The inclination angle of the inclined surface determines the bearing capacity of the bearing to the lateral thrust. Therefore, it is necessary to measure the angle of the rib inclination so that the produced products can meet the requirements of bearing the lateral thrust. Chinese patent (publication number: CN105823399B) discloses a bearing inner ring rib angle measurement device and measurement method, which is composed of a device body, and the device body includes a base, a positioning device and a measuring device; the base and the measuring device are connected to each other through a table rod provided on the base, and the positioning device is placed on the base, and is connected to each other through a limit block provided on the base and a limit push rod provided on the positioning device. The base is also provided with a micrometer frame, and the micrometer differential cylinder forms a surface contact with the positioning device by passing through a circular hole provided on the micrometer frame, which is used for positioning the positioning device.

[0003] However, the existing bearing inner ring rib angle measurement device has some disadvantages, such as:

[0004] Most of the existing bearing inner ring rib angle measurement results are expressed by micrometer readings, which makes the measured angle results not intuitive and fast enough. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a bearing inner ring rib angle detection device to solve the problem that the existing bearing inner ring rib angle measurement results are mostly expressed by micrometer readings, making the measured angle results not intuitive and fast enough.

[0006] Based on the above-mentioned purpose, the present invention provides a bearing inner ring rib angle detection device, including a base, two measuring mounting rods are vertically fixedly installed on the side of one end of the base, protractors are fixedly welded on the top of the two measuring mounting rods, the two protractors are arranged correspondingly, an angle measuring plate is rotatably installed between the two protractors, the top center of the angle measuring plate is rotatably connected to the protractor origin through a rotating shaft, a measuring mounting frame is vertically installed at the bottom center of the angle measuring plate, a reset spring is fixedly installed on one side of the measuring mounting frame close to the angle measuring plate, one end of the reset spring is fixedly connected to the inner wall of the measuring mounting frame, the other end of the reset spring is fixedly connected to a measuring slider, the measuring slider is slidably connected to the inner wall of the measuring mounting frame, and a measuring steel sheet is fixedly connected to the side of the measuring slider away from the reset spring, and the other end of the measuring steel sheet is arranged through the measuring mounting frame.

[0007] Furthermore, a card installation box is movably provided inside the base, and two limit sliders are movably provided inside the card installation box. The limit slider can slide inside the card installation box, and a limit spring is fixedly installed between the two limit sliders. The limit spring is used to push the two limit sliders to both sides, and limit rods are vertically fixedly installed on the top of the two limit sliders.

[0008] Furthermore, the tops of the two limit rods are each provided with an inclined block, and the inclined blocks provided on the tops of the limit rods are both arranged in opposite directions.

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0020] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, a bearing inner ring rib angle detection device comprises a base 1, wherein two measuring mounting rods 8 are vertically fixedly installed on the side of one end of the base 1, and protractors 9 are fixedly welded on the tops of the two measuring mounting rods 8, and the two protractors 9 are arranged correspondingly, and an angle measuring plate 10 is rotatably installed between the two protractors 9, and the top center of the angle measuring plate 10 is rotatably connected to the origin of the protractor 9 through a rotating shaft, and a measuring mounting frame 11 is vertically installed at the bottom center of the angle measuring plate 10, and a reset spring 7 is fixedly installed on the inside of the measuring mounting frame 11 near the side of the angle measuring plate 10, one end of the reset spring 7 is fixedly connected to the inner wall of the measuring mounting frame 11, and the other end of the reset spring 7 is fixedly connected to a measuring slider 6, and the measuring slider 6 is slidably connected to the inner wall of the measuring mounting frame 11, and a measuring steel sheet 12 is fixedly connected to the side of the measuring slider 6 away from the reset spring 7, and the other end of the measuring steel sheet 12 is arranged through the measuring mounting frame 11.

[0022] Among them, the edge of the measuring steel sheet 12 away from the measuring slider 6 is parallel to the edge of the top of the angle measuring plate 10. Therefore, the inclination angle of the bottom edge of the measuring steel sheet 12 can be reflected on the angle measuring plate 10. Conversely, by reading the deflection angle of the angle measuring plate 10, the angle measured by the measuring steel sheet 12 can be known.

[0023] When in use, the bearing inner ring to be tested is placed on the upper surface of the base 1, and then the bearing inner ring is gradually fitted on the base 1 and moved toward one side of the measuring mounting frame 11, and the measuring mounting frame 11 is rotated so that the end of the measuring steel sheet 12 always corresponds to the flange of the bearing inner ring. After the measuring steel sheet 12 contacts the flange of the bearing inner ring, the position of the bearing inner ring is continuously adjusted so that the side parallel to the top of the angle measuring plate 10 and the flange of the bearing inner ring coincide with each other. Since the measuring steel sheet 12 and one side of the top of the angle measuring plate 10 are parallel to each other, when the measuring steel sheet 12 coincides with the flange of the bearing inner ring, the deflection angle of the angle measuring plate 10 and the angle of the flange of the bearing inner ring will also be the same. By reading the deflection angle of the top side of the angle measuring plate 10, the angle of the flange of the bearing inner ring can be determined.

[0024] The present invention places one end of the measuring steel sheet 12 against the inclined surface of the inner ring rib of the bearing, so that the measuring steel sheet 12 can intuitively feed back the angle of the inclined surface of the inner ring rib of the bearing to the angle measuring plate 10, so that the user can clearly see the degree of inclination of the inner ring rib of the bearing, and at the same time can quickly read the inclination angle of the inner ring rib of the bearing by reading the angle between the angle measuring plate 10 and the protractor 9.

[0025] like Figure 1 , Figure 3As shown, further, a card installation box 5 is movably provided inside the base 1, and two limit sliders 3 are movably provided inside the card installation box 5. The limit slider 3 can slide inside the card installation box 5, and a limit spring 4 is fixedly installed between the two limit sliders 3. The limit spring 4 is used to push the two limit sliders 3 to both sides, and the tops of the two limit sliders 3 are both vertically fixed with limit rods 14;

[0026] Among them, the user can put the inner ring of the bearing on the two limit rods 14, and use the push of the limit spring 4 to make the limit rod 14 fix the inner ring of the bearing thereon. When the inner ring of the bearing is pushed on the base 1, the inner ring of the bearing can push the card installation box 5 to move inside the base 1. Through the limitation of the card installation box 5 and the limit rod 14, the inner ring of the bearing can move in a straight line on the base 1 and is not easy to fall off.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, further, the tops of the two limit rods 14 are both provided with inclined blocks, and the inclined blocks provided on the tops of the limit rods 14 are both provided in opposite directions. The inclined blocks are conveniently used to fix the inner ring of the bearing on the limit rod 14, so that the inner ring of the bearing is less likely to fall off from the limit rod 14.

[0028] like Figure 1 , Figure 3 As shown, further, a first limiting groove 13 is opened in the middle of the upper surface of the card installation box 5, and a second limiting groove 2 is opened in the middle of the upper surface of the base 1. The limiting rod 14 passes through the first limiting groove 13 and the second limiting groove 2 in sequence, and the limiting rod 14 can move in the first limiting groove 13 and the second limiting groove 2 at the same time.

[0029] Furthermore, the top side of the angle measuring plate 10 in a vertical state coincides with the zero scale line of the protractor 9. This allows the angle measuring plate 10 to be reset to zero when no angle measurement is performed, thereby ensuring the accuracy of the angle measurement of the device.

[0030] Furthermore, the protractor 9 is made of a transparent plastic material. By making the protractor 9 of a transparent material, the protractor 9 will not block the angle measuring plate 10, making it convenient to read the angle.

[0031] To sum up, when in use, the inner ring of the bearing to be tested is sleeved on the two limit rods 14, and the limit spring 4 is used to push the limit rod 14 to fix the inner ring of the bearing thereon, and the inclined clamping block is used to fix the inner ring of the bearing on the limit rod 14. When the inner ring of the bearing is pushed on the base 1, the inner ring of the bearing can push the clamp installation box 5 to move inside the base 1. Through the limitation of the clamp installation box 5 and the limit rod 14, the inner ring of the bearing can move in a straight line on the base 1 and is not easy to fall off. Then, the inner ring of the bearing is gradually fitted on the base 1 and moved toward the side of the measuring mounting frame 11, and the measuring mounting frame 11 is rotated. Make the end of the measuring steel sheet 12 always correspond to the rib of the inner ring of the bearing. After the measuring steel sheet 12 contacts the rib of the inner ring of the bearing, continue to adjust the position of the inner ring of the bearing so that the side parallel to the top of the angle measuring plate 10 and the rib of the inner ring of the bearing coincide with each other. Since the measuring steel sheet 12 and one side of the top of the angle measuring plate 10 are parallel to each other, when the measuring steel sheet 12 coincides with the rib of the inner ring of the bearing, the deflection angle of the angle measuring plate 10 will be the same as the angle of the rib of the inner ring of the bearing. By reading the deflection angle of the top side of the angle measuring plate 10, the angle of the rib of the inner ring of the bearing can be determined.
