Description

Technical Field

[0001] The utility model relates to the technical field of precision bearing detection, and specifically relates to a precision bearing raceway measuring device. Background Technique

[0002] The raceway of a precision bearing is the contact surface between the inner and outer rings of the bearing, which is used to support and guide the rolling elements (such as steel balls or rollers) to ensure the stable operation and long-term durability of the bearing under high-speed rotation and load conditions. The geometric dimensions of the bearing raceway are very crucial and directly affect the operating accuracy and efficiency of the bearing. The measuring device can accurately detect parameters such as the diameter, radius, roundness, circularity, and parallelism of the raceway to ensure that each raceway is within the specified tolerance range to support the stable rolling of the rolling elements.

[0003] However, most measuring devices usually place the bearing directly on the measuring table and drive the bearing to rotate through a turntable for rapid measurement. However, when in use, without a quick-fixing structure, the bearing may vibrate and shake, resulting in the bearing shifting, leading to inaccurate measurement data and the problem of the bearing falling off.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-3 , an embodiment provided by the present invention: A precision bearing raceway measuring device, including: an outer shell 1, and a motor 2 fixedly connected to the upper surface of the outer shell 1. The output end of the motor 2 extends downward through the upper wall of the outer shell 1 and is fixed with a gear 3. The outer wall of the gear 3 is meshed with a rack plate 4, and two sets of rack plates 4 are arranged oppositely, and the moving directions of the two sets of rack plates 4 are opposite and slide on the inner wall of the outer shell 1. The outer walls of the two sets of rack plates 4 are fixed with limit push rods 5. The outer wall of the limit push rod 5 is slidably connected to a support frame 6, and the outer shell 1 is fixed on the upper surface of the support frame 6. The outer wall of the limit push rod 5 is fixed with a connecting block 7. Above the connecting block 7 is fixed a slide block 9. The lower surface of the support frame 6 is fixed with a slide bar 8, and the inner wall of the slide block 9 slides on the outer wall of the slide bar 8. On the lower left and right sides and in the middle of the connecting block 7 are fixed a plurality of bearing clamping columns 10.

[0023] The operating table 21 slides on the outer wall of the support frame 6. A fixed block 11 is fixed below the operating table 21. A support seat 12 slides on the lower surface of the fixed block 11. A hydraulic cylinder 13 is fixed inside the support seat 12. The output end of the hydraulic cylinder 13 passes through the inside of the support seat 12 and is fixed on the lower surface of the fixed block 11. A limit block 14 slides inside the support seat 12. A first rotating shaft 15 is fixed inside the limit block 14.

[0024] A first adjusting rod 16 rotates on the outer wall of a first rotating shaft 15, and the outer wall of the first adjusting rod 16 slides inside a limiting block 14. A second rotating shaft 17 rotates inside the first adjusting rod 16. A limiting and adjusting plate 18 rotates on the outer wall of the second rotating shaft 17, and the outer wall of the limiting and adjusting plate 18 rotates on the upper inner wall of the support base 12 to play a role in limiting and supporting the first adjusting rod 16. A third rotating shaft 19 rotates inside the first adjusting rod 16. A second adjusting rod 20 rotates on the outer wall of the third rotating shaft 19, and the outer wall of the second adjusting rod 20 rotates on the inner wall of the fixed block 11. The first adjusting rod 16 and the third rotating shaft 19 are used to play a role in supporting and limiting the fixed block 11. The output end of a hydraulic cylinder 13 pushes the fixed block 11 to move. The limiting block 14 on the inner wall of the support base 12 slides on the inner wall of the support base 12 driven by the fixed block 11 to play a limiting role. The first adjusting rod 16 rotating on the outer wall of the first rotating shaft 15 plays a role in further limiting the fixed block 11, achieving the effects of the operation table 21 shifting and falling off.

[0025] Working principle: When the device needs to be used, the motor 2 drives the gear 3 to rotate on the inner wall of the housing 1. During use, the gear 3 drives the rack plate 4 to slide on the inner wall of the housing 1. The rack plate 4 can drive the limit push rod 5 to slide on the inner wall of the support frame 6, achieving the effect of the first limit during use. When the limit push rod 5 drives the connecting block 7 and the slider 9 to slide on the outer wall of the slide bar 8 during use, it achieves the effect of the second limit during use. The effect of multiple limits during use can further increase the stability when fixing the precision bearing, avoiding inaccurate measurement data caused by the offset of the bearing clamping column 10 during bearing fixation and the effect of bearing detachment. During use, the hydraulic cylinder 13 pushes or pulls the fixed block 11. When the fixed block 11 drives the second adjusting rod 20 to rotate on the inner wall of the third rotating shaft 19, the third rotating shaft 19 drives the first adjusting rod 16 and the second rotating shaft 17. With the limit of the limit adjusting plate 18, the stability of the fixed block 11 during lifting is ensured. When the first adjusting rod 16 rotates on the inner wall of the first rotating shaft 15 during use, the first rotating shaft 15 drives the limit block 14 to slide on the inner wall of the support base 12, achieving the limit effect during use, which can further avoid the problem of offset or one side being higher than the other side during lifting due to the instability of the fixed block 11. It also has the effect of being able to measure bearings of different heights by adjusting the height of the operating platform 21 according to the different heights of the precision bearings. During use, the device not only achieves the effect of quickly fixing the bearing by driving the bearing clamping column 10 through the connecting block 7, thus avoiding inaccurate measurement data caused by bearing offset and bearing detachment, but also has the effect of ensuring the stability of the operating platform 21 during use by pushing the second adjusting rod 20 with the first adjusting rod 16, and can adjust and fix the height for measurement according to bearings of different sizes.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
