Description

Technical Field

[0001] This utility model relates to the field of motorcycle manufacturing, and in particular to a groove diameter measuring device for motorcycle steering bearings without groove bottom. Background Technology

[0002] Bearings are essential components that fit onto shafts, supporting the rotation of mechanical parts and reducing friction during rotation. Steering bearings, also called column bearings, are installed on the steering column connecting the fork and frame. They act like a joint, allowing the handlebars and fork to move freely left and right, while bearing the weight of the front of the vehicle and various impacts from the road surface. After manufacturing, steering bearings require inspection and measurement, among which measuring the outer groove diameter is essential. For example, patent document CN215676804U discloses a device for measuring the inner and outer groove diameters of a double-groove bearing. This device includes a support table with a balance adjustment mechanism at the bottom for easy balancing. A measuring mechanism is located at one end of the support table to adjust the measurement angle and fix the bearing in place. A limiting mechanism is located at the end of the support table away from the measuring mechanism to restrict the bearing's movement for measuring its inner and outer diameters. A moving mechanism is located at the bottom of the limiting mechanism on the support table to rotate the bearing for inspection.

[0003] Currently, the measurement of the outer race groove diameter of steering bearings typically involves placing the outer race on a V-shaped support, manually holding the outer race, and pushing the support close to a dial indicator. The dial indicator's measuring head is then positioned at the lowest and highest points of the groove, and the groove diameter is obtained by measuring the difference between these two values. However, manually holding the outer race is not stable enough, and the support needs to be moved while holding the outer race, which is not precise enough, resulting in inaccurate measurement data. Utility Model Content

[0004] The purpose of this invention is to provide a groove diameter measuring device for motorcycle steering bearings without groove bottom in order to solve the above-mentioned problems.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6As shown, a groove-free motorcycle steering bearing groove diameter measuring device includes a base 1. A height adjustment mechanism 2 is located at the rear top of the base 1, and a lever dial indicator 3 is mounted on the height adjustment mechanism 2. The height adjustment mechanism 2 is used to adjust the height of the lever dial indicator 3. A translation mechanism 4 is located at the front top of the base 1, and a placement seat 5 is mounted on the translation mechanism 4. The bearing outer ring 7 to be measured is placed on the placement seat 5, and the measurement is performed using the lever dial indicator 3. A clamping mechanism 6 is mounted on the placement seat 5 to clamp the bearing outer ring 7 on the placement seat 5. The clamping mechanism 6 includes a horizontal guide rod 601, which is fixedly connected to the front side of the placement seat 5. A sliding plate is slidably connected to the horizontal guide rod 601. 602. A spring 603 is fixed between the slide plate 602 and the placement seat 5. The spring 603 is sleeved on the horizontal guide rod 601. Extension guide rods 604 are fixedly connected to both ends of the slide plate 602. A clamping block 605 is fixedly connected to the rear end of the extension guide rod 604. The extension guide rod 604 passes through the placement seat 5. After the bearing outer ring 7 is placed on the placement seat 5, the spring 603 applies a forward force to the slide plate 602. The slide plate 602 drives the clamping block 605 to move forward through the extension guide rod 604, so that the clamping block 605 clamps the bearing outer ring 7. The front corner of the top end of the extension guide rod 604 is set as a rounded corner. By setting the rounded corner, the bearing outer ring 7 can be directly inserted downward between the clamping block 605 and the placement seat 5, making it more convenient to use.

[0026] The placement seat 5 includes a V-shaped seat 501, which is fixedly mounted on the translation mechanism 4. The V-shaped seat 501 is used to place the outer ring 7 of the bearing, and it can accommodate bearing outer rings 7 of different diameters, thus improving versatility. A baffle 502 is fixedly connected to the front side of the V-shaped seat 501. The baffle 502 is used to prevent the outer ring 7 of the bearing from moving forward. The outer ring 7 of the bearing is clamped by the baffle 502 and the clamping block 605. A horizontal guide rod 601 is fixedly connected to the front side of the baffle 502. Guide blocks 503 are fixedly connected to both sides of the baffle 502. An extension guide rod 604 passes through the guide block 503.

[0027] A steel ball 5031 is slidably embedded in the inner wall of the guide block 503, and an arc groove 6041 that cooperates with the steel ball 5031 is provided on the extension guide rod 604. By setting the steel ball 5031, friction can be reduced, making the extension guide rod 604 move more smoothly and the use effect better.

[0028] The translation mechanism 4 includes a second threaded rod 401. A groove is provided on the top of the base 1. The second threaded rod 401 is rotatably connected in the groove. A second handle 402 is fixedly connected to the front end of the second threaded rod 401. A translation seat 403 is threadedly connected to the second threaded rod 401. The translation seat 403 is slidably connected in the groove. A V-shaped seat 501 is fixedly connected to the top of the translation seat 403. By rotating the second threaded rod 401 through the second handle 402, the second threaded rod 401 drives the translation seat 403 to move. The translation seat 403 drives the V-shaped seat 501 to move, thereby accurately adjusting the position of the outer ring 7 of the bearing and improving the measurement accuracy.

[0029] The height adjustment mechanism 2 includes a first threaded rod 201, which is fixedly connected to the top of the base 1. A first throttle 202 is fixedly connected to the top of the first threaded rod 201. A lifting seat 203 is threadedly connected to the first threaded rod 201. A lever dial indicator 3 is fixedly connected to the front end of the lifting seat 203. Multiple vertical guide rods 204 are fixedly connected to the top of the base 1. The lifting seat 203 is slidably connected to the vertical guide rods 204. By rotating the first threaded rod 201 through the first throttle 202, the first threaded rod 201 drives the lifting seat 203 to move up and down, thereby adjusting the height of the lever dial indicator 3 to accommodate bearing outer rings 7 of different diameters.

[0030] Working principle: In use, the outer ring 7 of the bearing is placed on the V-shaped seat 501. Since the clamping block 605 has rounded corners, the outer ring 7 of the bearing can be directly inserted between the clamping block 605 and the baffle 502. The spring force of the spring 603 clamps the outer ring 7 between the clamping block 605 and the baffle 502. Then, the second threaded rod 401 is rotated by the second throttle 402. The second threaded rod 401 drives the translation seat 403 to move backward, which in turn drives the V-shaped seat 501 to move backward, thus moving the lever dial indicator 3... The measuring head contacts the outer ring 7 of the bearing for measurement. The position of the outer ring 7 of the bearing can be adjusted more precisely by the second threaded rod 401, so that the measuring head of the lever dial indicator 3 can accurately contact the measuring position of the outer ring 7 of the bearing, thereby improving the accuracy of the measurement. For bearing outer rings 7 of different diameters, the first threaded rod 201 is rotated by the first throttle 202, and the first threaded rod 201 drives the lifting seat 203 to move up and down, thereby adjusting the height of the lever dial indicator 3 to adapt to bearing outer rings 7 of different diameters.
