Description

Technical Field

[0001] The utility model relates to the technical field of bearing measurement, in particular to a bearing ring measuring tool. Background Art

[0002] Bearings are used as rotating parts in various fields, such as automobiles, bicycles, etc. They have a wide range of uses. After the bearings are processed by processing equipment, the size of the bearings needs to be tested. If there is a deviation, the parameters can be adjusted in time to ensure that the processed bearings meet the requirements of the production process.

[0003] Currently, the parameters that need to be tested for bearings include inner diameter, outer diameter, circularity, etc. For the inner and outer diameter detection of bearings, the common detection method is to directly use a vernier caliper to detect them. By clamping the detection end of the vernier caliper on the outer diameter, it will be stuck in the position of the inner diameter, and directly reading the value on the vernier caliper, the inner and outer diameter dimensions of the bearing can be obtained.

[0004] Although the use of a vernier caliper can detect the inner and outer diameters of a bearing, the use of a vernier caliper to detect a bearing is prone to inaccurate readings and deviations due to improper operation. The vernier caliper should be used vertically so that the detection end can be vertically clamped on the bearing. In actual use, the vernier caliper may be inadvertently tilted for the convenience of measuring the degree, and the reading is read directly, which leads to inaccurate readings and deviations in the measured bearing size. Therefore, a bearing ring measuring tool is proposed to solve the above problem. Utility Model Content

[0029] Example

[0030] Reference Figure 1-Figure 6 The utility model provides a technical solution: a bearing ring measuring tool, including a processing seat 1 and a measuring mechanism 3, a support frame 2 is installed on the upper surface of the processing seat 1, the measuring mechanism 3 includes a cylinder 31, the cylinder 31 is fixedly installed on the top of the support frame 2, an extrusion rod 311 is installed on the protruding end of the cylinder 31, a rectangular plate 321 is installed on the support frame 2, an outer diameter clamping plate 32 is slidably installed on the bottom of the rectangular plate 321, a tray 331 is installed on the upper surface of the processing seat 1, an annular airbag bag 33 is bonded on the tray 331, the annular airbag bag 33 is connected with the inflatable bag 332 through a connecting pipe 333, and an inner diameter measuring plate 34 is slidably installed on the rectangular plate 321.

[0031] Control the squeezing rod 311 to move downward, and the bearing moves downward. The downward movement of the bearing will squeeze the annular airbag bag 33. After the annular airbag bag 33 is squeezed, the internal gas will be transported to the inside of the inflatable bag 332. The inflatable bag 332 will expand and squeeze the outer diameter clamping plate 32, so that the outer diameter clamping plate 32 is attached to the outer surface of the bearing, so as to improve the measurement accuracy of the outer diameter of the bearing and meet the use. At the same time, the inner diameter of the bearing is squeezed by the inner diameter measuring plate 34 to ensure the dimensional accuracy of the measured inner diameter of the bearing.

[0032] In a preferred embodiment, a scale 4 is fixedly installed on one side of the rectangular plate 321, a rectangular hole 5 is opened on the upper surface of the rectangular plate 321, a groove 6 is opened on the inner wall of the rectangular hole 5, a first spring 7 is fixedly connected to the inside of the groove 6, one end of the first spring 7 is fixedly connected to a slider 8, a connecting block 9 is fixedly installed on one side of the slider 8, an inner diameter measuring plate 34 is fixedly installed on the connecting block 9, a pointer 10 is installed on the upper end of the inner diameter measuring plate 34, and the device measures the inner diameter of the bearing. During operation, the bearing is placed above the tray 331, and the position of the inner diameter measuring plate 34 is made to correspond to the position of the inner side of the bearing, so that when the inner diameter measuring plate 34 descends, it will enter the inner side of the bearing, and under the pull of the first spring 7, the inner diameter measuring plate 34 will be tightly attached to the inner wall of the bearing to prevent gaps and improve measurement accuracy.

[0033] In a preferred embodiment, the upper surface of the processing seat 1 is fixedly connected to the support rod 11, the top of the support rod 11 is fixedly connected to the tray 331, and a hollow bin 12 is installed above the tray 331. The interior of the hollow bin 12 is slidably connected to a limit plate 13, and a second spring 14 is fixedly installed on one side of the limit plate 13. One end of the second spring 14 is fixedly connected to the inner wall of the hollow bin 12. For measuring the bearing size, it is necessary to limit the bearing so that it is stable on the receiving plate. In order to stably place the bearing on the receiving plate, a hollow bin 12 is installed on the upper end of the support rod 11, and a limit plate 13 is slidably installed inside the hollow bin 12. Under the push of the second spring 14, the limit plate 13 will make the plate 13 close to the inner side of the bearing, so that it cannot move at will, and prevents deviation, so as to stably measure the size of the bearing.

[0034] In a preferred embodiment, the outer part of the rectangular plate 321 is slidably connected to the moving block 15, the moving block 15 is fixedly connected to the outer diameter clamping plate 32, and the scale needle 16 is fixedly installed on the moving block 15. This device can not only measure the inner diameter of the bearing, but also measure the outer diameter of the bearing. In order to facilitate the control of the outer diameter clamping plate 32 to move to the outer surface of the bearing, the moving block 15 is slidably installed on the rectangular plate 321, and the moving block 15 is fixedly connected to the outer diameter clamping plate 32, so as to facilitate the control of the outer diameter clamping plate 32 to move to the outer surface of the bearing to measure the outer diameter of the bearing.

[0035] In order to facilitate the placement of the bearing on the receiving plate, the inner diameter measuring plate 34 of the device needs to be moved upward to leave enough space between the inner diameter measuring plate 34 and the receiving plate. Therefore, the cylindrical rod 17 is fixedly connected to the upper surface of the processing seat 1, and one end of the cylindrical rod 17 is arranged inside the support frame 2 and is slidably connected to the inside of the support frame 2. A positioning pin 18 is inserted into the inside of the support frame 2, and the positioning pin 18 passes through the inside of the cylindrical rod 17. When not in use, the support frame 2 of the device is in the highest state. At this time, there is a sufficiently large distance between the inner diameter measuring plate 34 and the receiving plate, so as to facilitate the placement of the bearing on the receiving plate. After the placement is completed, the support frame 2 is controlled to move downward to shorten the distance between the inner diameter measuring plate 34 and the bearing, and the bottom end of the inner diameter measuring plate 34 is extended to the position inside the bearing to measure the inner diameter size of the bearing.

[0036] After the bearing is processed, the staff takes it and places it on the device for measurement. Since the medium roughness is made of metal, iron filings and small particles will be generated during the processing. When the small particles adhere to the outer surface of the bearing, it is not easy to be found. However, during measurement, they are easily clamped by the outer diameter clamping plate 32, causing the outer diameter clamping plate 32 to be unable to fit with the outer surface of the bearing, which will affect the measurement accuracy of the outer diameter of the bearing. Therefore, a particle removal mechanism 19 is installed at the telescopic end of the cylinder 31. The particle removal mechanism 19 includes a rotating disk 191, The protrusion 192 and the airbag package 193, the telescopic end of the cylinder 31 is rotatably connected to the hollow cylinder, the outer surface of the hollow cylinder is fixedly installed with a rotating disk 191, the bottom of the rotating disk 191 is fixedly connected to the vertical rod 22, the outside of the vertical rod 22 is provided with a mounting plate 20, the vertical rod 22 passes through the interior of the mounting plate 20 and is rotatably connected to the interior of the mounting plate 20, the bottom of the mounting plate 20 is fixedly installed with an extrusion rod 311, the outer side surface of the rotating disk 191 is provided with a protrusion 192, and the annular airbag bag 33 is connected to the airbag package 193 through the air supply pipe 21.

[0037] During operation, the cylinder 31 pushes the vertical rod 22 to move downward, so that the vertical rod 22 squeezes the bearing and improves the bearing limiting effect. When the telescopic end of the cylinder 31 is extended, it will also drive the squeezing rod 311 to move downward, and the squeezing rod 311 will also squeeze the bearing to limit the position. The squeezing force of the squeezing rod 311 will be less than the squeezing force of the vertical rod 22 on the bearing. Then the rotating disk 191 is controlled to rotate to drive the vertical rod 22 to rotate. The bearing will also rotate under the strong squeezing of the vertical rod 22, thereby driving the bearing to rotate. At the same time, after the bearing is squeezed, it will also squeeze the annular airbag bag 33. The gas inside the annular airbag bag 33 will be squeezed into the interior of the airbag bag 193. At this time, the airbag bag 193 will stick to the outer surface of the bearing. When the bearing rotates, the attached particles can be removed by the airbag bag 193, thereby improving the measurement accuracy of the centering coarse and meeting the use requirements.

[0038] Specifically, the working process or working principle of a bearing ring measuring tool is as follows: Currently, the parameters that need to be tested for bearings include inner diameter, outer diameter, circularity, etc. For the inner and outer diameter detection of bearings, a common detection method is to directly use a vernier caliper to detect them. By clamping the detection end of the vernier caliper on the outer diameter, it will be stuck in the position of the inner diameter, and directly reading the value on the vernier caliper, the inner and outer diameter dimensions of the bearing can be obtained.

[0039] Although the use of a vernier caliper can detect the inner and outer diameters of a bearing, the use of a vernier caliper to detect a bearing is prone to inaccurate readings and deviations due to improper operation. The vernier caliper must be used vertically so that the detection end can be vertically clamped on the bearing. In actual use, the vernier caliper may be inadvertently tilted for the convenience of measuring the degree, and the reading is directly taken, which results in inaccurate readings and deviations in the measured bearing size. Therefore, this device is designed to solve this problem.

[0040] The device is used to measure the size of the bearing and can improve the measurement accuracy to meet the needs of use. The specific use is: first connect the external power supply, place the bearing to be measured on the tray 331, and the device is slidably installed with a receiving plate on the outside of the support rod 11. The bearing will be placed on the receiving plate, and the limit plate 13 will be sleeved on the inside of the inner ring of the bearing. At this time, the limit plate 13 will extend outward under the action of the second spring 14, and press against the inner wall of the inner ring of the bearing to limit it, so that the bearing can be stably placed on the receiving plate.

[0041] After limiting the bearing, the positioning pin 18 is pulled out from the inside of the support frame 2. At this time, the support frame 2 will move downward under the action of its own gravity. After one end of the inner diameter measuring plate 34 enters the position inside the bearing, the positioning pin 18 can be inserted into the inside of the support frame 2 again to position the support frame 2. At the same time, it can also ensure that the outer diameter clamping plate 32 and the inner diameter measuring plate 34 measure the outer diameter and inner diameter of the bearing.

[0042] The device is provided with a vertical rod 22 at the bottom of the rotating disk 191. When the cylinder 31 is turned on, the protruding end of the cylinder 31 will extend out and push the squeezing rod 311 and the vertical rod 22 to move downward, and the bearing will be squeezed by the squeezing rod 311, and the vertical rod 22 will also squeeze the bearing. As the squeezing force continues to increase, the bearing will continue to move downward and squeeze the annular air bag 33, and the gas inside the annular air bag 33 will be pressed into the interior of two inflatable bags 332 and an air bag bag 193 respectively, and expand. When the inflatable bag 332 expands and becomes larger, it will push the outer diameter clamping plate 32, so that the outer diameter clamping plate 32 is tightly attached to the outer surface of the bearing. When the air bag bag 193 expands and becomes larger, it will be attached to the outer surface of the bearing. Then, the rotating disk 191 is controlled to rotate, which will drive the bearing to rotate, so that the small particles on the outer surface of the bearing are removed by the expanded air bag bag 193, so as to avoid the outer diameter clamping plate 32 squeezing small particles and causing inaccurate measurement.

[0043] The device squeezes the bearing through the vertical rod 22. When the squeezing force is large, the bearing will be driven to rotate through the rotation of the vertical rod 22.

[0044] When the outer diameter clamping plate 32 is attached to the outer surface of the bearing, the scale needle 16 integrated with the outer diameter clamping plate 32 will point to a certain value on the scale 4. The two scale needles 16 point out two values ​​on one scale 4, and the difference between the two values ​​is the outer diameter size of the bearing.

[0045] The inner diameter of the bearing is measured by the inner diameter measuring plate 34, which will be tightly attached to the inner wall of the inner ring of the bearing under the action of the first spring 7. Similarly, the two pointers 10 point to the values ​​on the scale 4, and the difference between the two values ​​is the inner diameter size of the bearing.

[0046] Therefore, the device is convenient for measuring the inner diameter and outer diameter of the bearing and ensures the measurement accuracy so as to meet the use requirements.

[0047] It should be noted that the cylinder 31 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
