Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a tapered roller diameter detection device. Background Technology

[0002] In the machinery manufacturing and precision machining industries, tapered rollers serve as key transmission and support components, and the accuracy and consistency of their diameter significantly impact the overall performance and lifespan of the equipment. Traditional methods for measuring the diameter of tapered rollers often employ caliper measuring tools. While this method is simple and direct, it has some inherent limitations in practical operation.

[0003] First, the accuracy and stability of caliper measuring tools are easily affected by the operator's skill and experience; different operators may produce different measurement results due to different operating techniques. Second, when selecting two points to measure the diameter of a tapered roller, it is difficult to ensure that these two points are perfectly perpendicular and centered, which can easily lead to skewness and affect the accuracy of the measurement results. Furthermore, traditional measurement methods typically only measure specific parts of the tapered roller and cannot comprehensively reflect changes in its diameter. This limitation is particularly pronounced for high-precision tapered rollers that require strict control over diameter consistency. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a tapered roller diameter detection device, which has the advantages of being able to detect tapered roller diameter in a more standardized, accurate and comprehensive manner, and solves some of the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a tapered roller diameter detection device, including a detection platform, a frustum at the middle of the upper end of the detection platform, a fixed frame fixedly connected to the upper end of the frustum, a lifting groove I at the middle of both the left and right ends of the fixed frame, a pressure plate slidably installed inside the lifting groove I, two sets of measuring blocks slidably installed on the outer side of the pressure plate, a scale I at the upper end of the pressure plate near the front side, an inner conical hole seat fixedly installed at the middle of the upper end of the frustum, a lifting groove II at the lower side of the lifting groove I at both the left and right ends of the fixed frame, a measuring plate slidably installed inside the lifting groove II, and a scale II at the right end of the fixed frame corresponding to the lifting groove II.

[0006] Furthermore, a threaded rod is threaded through and connected to the middle of the upper end of the fixing frame, and the lower end of the threaded rod is rotatably connected to the pressure plate. The threaded rod is used to control the lifting and clamping of the pressure plate.

[0007] Furthermore, a sliding rod is fixedly installed in the middle of the interior of the second lifting groove. A tension spring is provided on the outer side of the sliding rod between the upper end of the measuring plate and the inner top of the second lifting groove. The rebound effect of the tension spring can make the measuring plate fit tightly against the lower end face of the tapered roller, and it also has self-adaptability, making it more flexible and convenient to use.

[0008] Furthermore, an electric push rod is fixedly installed at the upper end of the detection platform near each of the four corners. A lifting platform is fixedly installed between the upper output ends of the electric push rods. The lifting function of the lifting platform is used to keep the displacement sensor moving up and down synchronously, thereby improving the accuracy of the detection data.

[0009] Furthermore, displacement sensors are slidably installed at the middle of both the front and rear sides of the upper end of the lifting platform, and electric push rods are fixedly installed at the middle of both the front and rear sides of the upper end of the lifting platform. The output ends of the electric push rods are fixedly connected to the displacement sensors. When detecting tapered rollers of different sizes, it may be necessary to adjust the position of the displacement sensors to a suitable position so that the probe part contacts the smallest diameter part of the lower end of the tapered roller.

[0010] Furthermore, a slot is provided at the middle of the upper end of the truncated cone, which is adapted to the probe of the displacement sensor. A through groove adapted to the slot is provided on the inner conical hole seat. A sliding groove is also provided inside the inner conical hole seat in the left and right direction. The measuring plate passes through and slides inside the sliding groove, which ensures the rationality of the structural design and avoids structural conflicts during testing.

[0011] The advantages of this utility model are as follows:

[0012] 1. The tapered roller diameter detection device proposed in this utility model achieves stable clamping of the tapered roller through the cooperation of the pressure plate and the inner tapered hole seat, ensuring that the tapered roller remains centered and vertical during the measurement process. This design effectively eliminates the error caused by the skew of the measurement point in traditional tooth clamp measurement, improving the accuracy and stability of the measurement. At the same time, the use of a displacement sensor for linear measurement further enhances the accuracy and reliability of the measurement, providing a strong guarantee for the quality control of tapered rollers.

[0013] 2. This device can not only measure the diameter data of the upper and lower ends of the tapered roller, but also calculate the diameter data of the tapered roller at any cross-section by adjusting the position of the displacement sensor and the lifting operation. This comprehensive and detailed measurement method allows the inspection personnel to have a more complete understanding of the diameter variation of the tapered roller, which is convenient for comparison and analysis with standard data. This enables timely detection and adjustment of problems in the production process, improving the processing quality and consistency of the tapered roller. In addition, this measurement method also reduces the error risk caused by local measurement, providing strong support for the high-precision manufacturing of tapered rollers.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3A tapered roller diameter testing device includes a testing platform 1, a frustum 2 at the upper center of the testing platform 1, a fixed frame 3 fixedly connected to the upper end of the frustum 2, lifting grooves 4 at the middle of both ends of the fixed frame 3, a pressure plate 5 slidably installed inside the lifting grooves 4, two sets of measuring blocks 6 slidably installed on the outer side of the pressure plate 5, a scale 7 near the front of the upper end of the pressure plate 5, an inner tapered hole seat 8 fixedly installed at the middle of the upper end of the frustum 2, and lifting grooves at the lower sides of both ends of the fixed frame 3 near the lifting grooves 4. A measuring plate 11 is slidably installed inside the second lifting groove 10. A scale 14 is provided on the right end of the fixed frame 3 at the corresponding position in the second lifting groove 10. A threaded rod 9 is threaded through and connected to the middle of the upper end of the fixed frame 3. The lower end of the threaded rod 9 is rotatably connected to the pressure plate 5. A sliding rod 12 is fixedly installed in the middle of the interior of each lifting groove 10. A tension spring 13 is provided on the outer side of the sliding rod 12 between the upper end of the measuring plate 11 and the inner top of the second lifting groove 10. The smaller diameter end of the tapered roller is placed inside the inner tapered hole seat 8. By rotating the threaded rod 9, the pressure plate 5 is lowered and pressed against the upper end of the tapered roller, causing the tapered roller to descend to its lowest point and stop. At this point, the tapered roller is in a centered and vertical state after being limited by the inner tapered hole seat 8 and the pressure plate 5. Thus, the sliding measuring block 6 is pressed tightly against the upper end of the tapered roller. By observing the value corresponding to the measuring block 6 on the scale 7, the maximum diameter of the upper end of the tapered roller can be obtained. At the same time, during the descent of the tapered roller, the measuring plate 11 is lowered, and the rebound of the tension spring 13 is used to... The measuring plate 11 can be positioned so that its upper end is in close contact with the lower end of the tapered roller. At this time, the lower end of the tapered roller is positioned inside the inner tapered hole seat 8 at a fixed value. By calculating in advance the relationship between the height position on the scale 14 and the diameter of the inner circle of the inner tapered hole seat 8, the diameter data of the lower end of the tapered roller can be obtained directly from the corresponding value on the scale 14 of the measuring plate 11. Compared with the use of caliper measurement, this device is more standardized and regulated in operation, and there will be no skew between the two points of the selected diameter, resulting in more accurate test results.

[0020] Please see Figures 1-2Electric push rods 15 are fixedly installed at the upper end of the testing platform 1 near the four corners. A lifting platform 16 is fixedly installed between the upper output ends of the electric push rods 15. Displacement sensors 17 are slidably installed at the middle of the front and rear sides of the upper end of the lifting platform 16. Electric push rods 18 are fixedly installed at the middle of the front and rear ends of the upper end of the lifting platform 16. The output ends of electric push rods 18 are fixedly connected to the displacement sensors 17. A slot 19 is provided at the middle of the upper end of the frustum 2. The slot 19 is adapted to the probe of the displacement sensor 17. A through groove adapted to the slot 19 is provided on the inner conical hole seat 8. A sliding groove 20 is also provided in the left and right directions inside the inner conical hole seat 8. The measuring plate 11 passes through and slides. Connected inside the slide 20, the tapered roller is clamped and fixed at both ends by the cooperation of the pressure plate 5 and the inner tapered hole seat 8. Therefore, the position of the displacement sensor 17 is adjusted by the electric push rod 18 so that its probe extends into the slot 19 and contacts the lowest side of both ends of the tapered roller. By opening the electric push rod 15, the lifting platform 16 drives the displacement sensor 17 to rise, so that the probes of the symmetrically arranged displacement sensor 17 rise linearly along both ends of the tapered roller. Then, the diameter data of the tapered roller at any cross section can be calculated, and the detection results are more comprehensive. This makes it convenient for the inspection personnel to make detailed comparisons with standard data, thereby better controlling and adjusting the production of tapered rollers and improving the processing quality.

[0021] Working principle: The smaller diameter end of the tapered roller is placed inside the inner tapered hole seat 8. By rotating the threaded rod 9, the pressure plate 5 is lowered and pressed against the upper end of the tapered roller, causing the tapered roller to descend to its lowest point and stop. At this point, the tapered roller is centered and vertical after being limited by the inner tapered hole seat 8 and the pressure plate 5. The sliding measuring block 6 is then pressed tightly against the upper end of the tapered roller. By observing the value corresponding to the scale 7 on the measuring block 6, the maximum diameter of the upper end of the tapered roller can be obtained. Simultaneously, during the descent of the tapered roller, the measuring plate 11 is also lowered. The rebound action of the tension spring 13 ensures that the upper end of the measuring plate 11 is pressed tightly against the lower end of the tapered roller. At this point, the lower end of the tapered roller is located inside the inner tapered hole seat 8. By calculating the relationship between the height position on scale 14 and the diameter of the inner circle of the inner conical hole seat 8 in advance, the diameter data of the lower end of the tapered roller can be directly obtained from the corresponding value on scale 14 of the measuring plate 11. Furthermore, since the upper and lower ends of the tapered roller are clamped and fixed by the cooperation of the pressure plate 5 and the inner conical hole seat 8, the position of the displacement sensor 17 is adjusted by the electric push rod 18 so that its probe extends into the slot 19 and contacts the lowest side of both ends of the tapered roller. By opening the electric push rod 15, the lifting platform 16 drives the displacement sensor 17 to rise, so that the probes of the symmetrically arranged displacement sensor 17 rise linearly along both ends of the tapered roller, and the diameter data of the tapered roller at any cross section can be calculated.
