Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and more specifically, to a bearing inner and outer ring size detection device. Background Technology

[0002] The function of bearings is to make rotation in machinery smoother. They use balls, rollers or sliding surfaces to replace the direct friction between the shaft and the hole. They can support huge loads, increase the rotation speed and minimize wear and heat. From bicycle wheels and electric drills to aircraft engines, bearings are almost indispensable wherever there is rotation.

[0003] During bearing manufacturing, the dimensions of the inner and outer rings need to be inspected to ensure they meet factory standards. However, most existing methods involve manual measurement using tools such as calipers and micrometers. Due to factors such as skill level and measurement angle, it is difficult to guarantee that the actual measured dimensions are the diameters of the inner and outer rings, resulting in poor measurement accuracy. This necessitates multiple re-measurements and calibrations, impacting inspection efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bearing inner and outer ring size detection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing inner and outer ring size detection device, comprising a base and a clamping assembly;

[0006] Two brackets are fixedly connected to the base, a slide rail is fixedly connected to the base, and multiple slide blocks are slidably connected to the slide rail. A top column is fixedly connected to the upper end face of each of the multiple slide blocks. The multiple top columns abut against the inner ring side wall and the outer ring side wall of the bearing, respectively. An outer ring cross arm, an inner ring cross arm, an inner ring indicator rod, and an outer ring indicator rod are fixedly connected to the side wall of each of the multiple slide blocks. An outer ring ruler is fixedly connected to the outer ring cross arm, and an inner ring ruler is fixedly connected to the inner ring cross arm.

[0007] The clamping assembly is mounted on the base and is used to clamp and position the bearing so that the centers of the inner and outer rings of the bearing are located on the line connecting multiple top posts.

[0008] Preferably, the clamping assembly includes a fixed column, a stand, guide rods, and a movable column. There are two fixed columns, both of which are fixedly connected to the base. The stand is fixedly connected to the base, and two guide rods are slidably connected to the stand. One end of each of the two guide rods is fixedly connected to a movable column.

[0009] Preferably, the ends of both guide rods furthest from the movable column are fixedly connected to the pull plate.

[0010] Preferably, springs are fitted onto the two guide rods respectively, and both springs are located between the upright and the two movable columns.

[0011] Preferably, the inner ring indicator rod abuts against the lower end face of the inner ring ruler, and the outer ring indicator rod abuts against the lower end face of the outer ring ruler.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The bearings on the two brackets are clamped and positioned by the clamping assembly, so that the centers of the inner and outer rings of the bearings are located on the line connecting multiple push pins. Then, the push pins are moved so that the two push pins in the middle contact with the two sides of the inner ring of the bearing, and the two push pins on the sides contact with the two sides of the outer ring of the bearing. At this time, the value indicated by the inner ring indicator on the inner ring ruler is the inner ring diameter of the bearing, and the value indicated by the outer ring indicator on the outer ring ruler is the outer ring diameter of the bearing. Since the centers of the inner and outer rings of the bearings are located on the line connecting multiple push pins, the measured inner and outer ring diameters can be ensured to be accurate, eliminating the need for multiple re-measurements and calibrations, and improving the testing efficiency.

[0023] Reference Figures 1 to 3 This utility model provides a technical solution: a bearing inner and outer ring size detection device, including a base 1 and a clamping assembly;

[0024] Two brackets 2 are fixedly connected to the base 1, such as Figure 1 and Figure 3 The bearing is placed on two brackets 2 and supported by the two brackets 2. A slide rail 3 is fixedly connected to the base 1. Multiple slide blocks 4 are slidably connected to the slide rail 3. A top column 5 is fixedly connected to the upper end face of the multiple slide blocks 4. The multiple top columns 5 are located on the same straight line. The multiple top columns 5 abut against the inner ring side wall and the outer ring side wall of the bearing respectively. An outer ring cross arm 6, an inner ring cross arm 7, an inner ring indicator rod 8 and an outer ring indicator rod 9 are fixedly connected to the side wall of the multiple slide blocks 4 respectively. An outer ring ruler 10 is fixedly connected to the outer ring cross arm 6 and an inner ring ruler 11 is fixedly connected to the inner ring cross arm 7.

[0025] like Figure 1 and Figure 3 Multiple slide blocks 4 can slide along the slide rail 3 respectively, and multiple slide blocks 4 can drive the top column 5 on them to move respectively. Furthermore, multiple slide blocks 4 can drive the outer ring horizontal arm 6, the inner ring horizontal arm 7, the inner ring indicator rod 8 and the outer ring indicator rod 9 to move respectively. The outer ring horizontal arm 6 and the inner ring horizontal arm 7 drive the outer ring ruler 10 and the inner ring ruler 11 to move respectively.

[0026] The clamping assembly is mounted on the base 1 and is used to clamp and position the bearing so that the centers of the inner and outer rings of the bearing are located on the line connecting the multiple top posts 5.

[0027] like Figure 1 and Figure 3 The bearings on the two brackets 2 are clamped and positioned by the clamping assembly so that the center of the inner and outer rings of the bearings is located on the line connecting multiple top posts 5. Then, the multiple top posts 5 are moved so that the two top posts 5 in the middle abut against the two sides of the inner ring of the bearing, and the two top posts 5 on the sides abut against the two sides of the outer ring of the bearing. At this time, the value indicated by the inner ring indicator rod 8 on the inner ring ruler 11 is the inner ring diameter of the bearing, and the value indicated by the outer ring indicator rod 9 on the outer ring ruler 10 is the outer ring diameter of the bearing.

[0028] Since the centers of the inner and outer rings of the bearing are located on the line connecting multiple top posts 5, the measured inner and outer ring diameters can be ensured to be accurate, eliminating the need for multiple re-measurements and calibrations, thus improving testing efficiency.

[0029] Specifically, the clamping assembly includes a fixed column 12, a stand 13, a guide rod 14, and a movable column 15. There are two fixed columns 12, both of which are fixedly connected to the base 1. The stand 13 is fixedly connected to the base 1. Two guide rods 14 are slidably connected to the stand 13. One end of each of the two guide rods 14 is fixedly connected to a movable column 15.

[0030] like Figure 1 and Figure 2 Two fixed posts 12 and two movable posts 15 form a rectangular clamp. Pushing two guide rods 14 causes the two movable posts 15 to move toward the bearing, and causes both the two fixed posts 12 and the two movable posts 15 to come into contact with the bearing, thereby completing the clamping and positioning of the bearing, so that the center of the inner and outer rings of the bearing is located on the line connecting multiple top posts 5.

[0031] Specifically, the ends of both guide rods 14 furthest from the movable column 15 are fixedly connected to the pull plate 16, such as... Figure 2 The pull plate 16 can simultaneously drive the two guide rods 14 to move.

[0032] Specifically, springs 17 are respectively fitted on the two guide rods 14, and the two springs 17 are located between the upright 13 and the two movable columns 15;

[0033] like Figure 2 The spring 17 pushes the movable column 15 toward the fixed column 12, and under the thrust of the spring 17, the movable column 15 and the fixed column 12 complete the clamping and positioning of the bearing.

[0034] Specifically, the inner ring indicator rod 8 abuts against the lower end face of the inner ring ruler 11, and the outer ring indicator rod 9 abuts against the lower end face of the outer ring ruler 10.

[0035] like Figure 3 The inner ring indicator rod 8 and the outer ring indicator rod 9 can support the inner ring ruler 11 and the outer ring ruler 10, thereby providing auxiliary support for the inner ring ruler 11 and the outer ring ruler 10.

[0036] Working principle: The bearings on the two brackets 2 are clamped and positioned by the clamping assembly, so that the center of the inner and outer rings of the bearings are located on the line connecting multiple top posts 5. Then, the multiple top posts 5 are moved so that the two top posts 5 in the middle contact with the two sides of the inner ring of the bearing, and the two top posts 5 on the sides contact with the two sides of the outer ring of the bearing. At this time, the value indicated by the inner ring indicator rod 8 on the inner ring ruler 11 is the inner ring diameter of the bearing, and the value indicated by the outer ring indicator rod 9 on the outer ring ruler 10 is the outer ring diameter of the bearing.
