Description

Technical Field

[0001] This utility model relates to the technical field of annular forgings, specifically a tool for detecting the roundness of annular forgings. Background Technology

[0002] Ring forgings are often used as core load-bearing or connecting components (such as bearing outer rings and pipe flanges). If their roundness error is too large, it will lead to uneven clearance with shafts, bolts and other accessories. This can cause "jamming" in mild cases and complete failure to assemble in severe cases, resulting in the rework of the entire equipment.

[0003] Therefore, in order to ensure the precise fit of the ring forgings during assembly and the structural safety during service, it is necessary to perform roundness testing on the finished ring forgings, thereby improving their operating accuracy, lifespan and reliability on the corresponding equipment.

[0004] However, the current method for inspecting ring forgings is to select 8-12 measuring points evenly on the circumference of the ring forging, then rotate the ring forging and record the readings of the deviation of each point. Half of the maximum difference is the roundness error. This method is suitable for rough machining or quick on-site sampling inspection, but it is inefficient and has poor accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a tool for detecting the roundness of ring forgings, which solves the problem of low efficiency in detecting the roundness of ring forgings, improves the accuracy and efficiency of detecting the roundness of ring forgings, and reduces the labor intensity of manual labor.

[0006] To achieve the above objectives, the utility model employs the following technical solution: A roundness inspection tool for annular forgings includes a base and a turntable for fixing the annular forging. The turntable is rotatably mounted on the base. Multiple sliders are slidably connected to the turntable radially. Clamping blocks that contact the annular forging are slidably connected to the sliders. Two clamping blocks are respectively provided between the sliders and the clamping blocks. A detection mechanism is provided on the base. The detection mechanism includes a movable seat slidably mounted on the base. A roller that contacts the annular forging is rotatably connected to the movable seat. A limiting plate is provided on the base. A tension spring is provided between the limiting plate and the movable seat. A distance sensor is provided on the other side of the limiting plate. A baffle plate that cooperates with the distance sensor is provided on the movable seat.

[0007] Furthermore, a receiving plate that slidably connects to the slider and contacts the annular forging or clamping block is provided on one side of the receiving plate. A limiting rod is provided on one side of the receiving plate. A through hole is provided on the slider for the limiting rod to pass through. A number of limiting holes that contact the limiting rod are provided on the turntable. A second spring is provided between the receiving plate and the slider.

[0008] Furthermore, the end of the limiting rod is provided with a first inclined surface that contacts the limiting hole.

[0009] Furthermore, the end of the clamping block is provided with a second inclined surface.

[0010] Furthermore, the end of the clamping block is provided with a friction part.

[0011] Furthermore, the detection mechanism consists of multiple sets, evenly arranged on the base.

[0012] Furthermore, a bearing is provided between the base and the turntable.

[0013] Furthermore, the base is provided with a drive motor, the movable end of the drive motor is provided with a drive gear, and the end of the turntable is provided with a toothed ring that meshes with the drive gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When the size of the ring forging changes, first slide the slider on the turntable, and move the two clamping blocks on the slider together to adapt to the fixing of ring forgings of different sizes. This breaks the limitation of one clamp for one size, reduces the manufacturing and storage costs of the clamps, and when changing ring forgings of different sizes, there is no need to change the entire set of clamps. Only the positioning of the slider needs to be adjusted, which greatly shortens the time for testing different types of ring forgings and improves the utilization rate of the testing equipment. 2. When it is necessary to fix the ring forging, place the ring forging on the slide plate. By pressing the two clamping blocks, the first spring between the clamping blocks and the slide plate is compressed. At the same time, the movable seat on the base is pulled inward to stretch the tension spring between the limiting plate and the movable seat, so that the ring forging passes smoothly through the clamping blocks and rollers and falls onto the turntable. Then, the external force is removed. The rebound force generated after the first spring is compressed is applied to the ring forging through the clamping blocks. Combined with its own weight, this restricts the movement of the ring forging on the turntable. In addition, the friction between the clamping blocks and the ring forging, as well as the friction between the ring forging and the turntable, restricts the rotation of the ring forging relative to the turntable. This allows for the fixing of ring forgings of different widths, further reducing the manufacturing and storage costs of the fixture, shortening the time for inspecting different types of ring forgings, and improving the utilization rate of the inspection equipment. 3. After fixing the annular forging, remove the external force applied to the movable seat. Under the action of the spring return force, the movable seat will slide on the base until the roller contacts the annular forging. Record this point on the annular forging as the zero-point positioning. Then, turn on the ultrasonic ranging sensor and rotate the turntable on the base, causing the annular forging to rotate relative to the base. When the inner diameter of the measuring point is smaller than the inner diameter of the zero-point positioning, the annular forging will further contact the roller, causing the baffle on the movable seat to move inward. When the inner diameter of the measuring point is larger than the inner diameter of the zero-point positioning, under the action of the spring return force, the baffle on the movable seat will move outward. The movement of the baffle is recorded by the ultrasonic ranging sensor, thus forming a detection curve for the annular forging. By analyzing the highest and lowest points of the detection curve, as well as the smoothness of the curve changes, it is possible to quickly determine whether the roundness of the inner diameter of the annular forging is qualified. At the same time, it is not necessary to manually measure the changes of multiple points, improving the accuracy and efficiency of detecting the roundness of the annular forging and reducing the labor intensity.

[0019] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0020] This utility model provides a tool for detecting the roundness of ring forgings, such as... Figure 1 and Figure 2As shown, the device includes a base 1 and a turntable 3 for fixing an annular forging 2. The turntable 3 is rotatably mounted on the base 1. Multiple sliders 4 are slidably connected to the turntable 3 radially. Clamping blocks 5 that contact the annular forging 2 are slidably connected to the sliders 4. A first spring 6 is provided between each of the two clamping blocks 5 and the sliders 4. When it is necessary to inspect annular forgings 2 of different sizes, the sliders 4 are slid on the turntable 3, which moves the two clamping blocks 5 on the sliders 4 together, thereby adapting to the fixing of annular forgings 2 of different sizes. This breaks the limitation of one clamp for each size, reduces the manufacturing and storage costs of the clamps, and when changing annular forgings 2 of different sizes, it is not necessary to change the entire set of clamps. Only the positioning of the sliders 4 needs to be adjusted, thereby greatly shortening the time for inspecting different types of annular forgings 2 and improving the utilization rate of the inspection equipment. When it is necessary to fix the annular forging 2, the annular forging 2 is placed on the slide plate. By pressing the two clamping blocks 5, the first spring 6 between the clamping blocks 5 and the slide plate is compressed, allowing the annular forging 2 to pass smoothly through the clamping blocks 5 and fall onto the turntable 3. Then, the external force is removed, and the rebound force generated after the first spring 6 is compressed is applied to the annular forging 2 through the clamping blocks 5. Combined with its own weight, this restricts the movement of the annular forging 2 on the turntable 3. In addition, the friction between the clamping blocks 5 and the annular forging 2, as well as the friction between the annular forging 2 and the turntable 3, restricts the rotation of the annular forging 2 relative to the turntable 3. This enables the fixing of annular forgings 2 of different widths, further reducing the manufacturing and storage costs of the fixture, shortening the time for inspecting different types of annular forgings 2, and improving the utilization rate of the inspection equipment. The base 1 is equipped with a detection mechanism, which includes a movable seat 7 slidably mounted on the base 1. A roller 8, which contacts the annular forging 2, is rotatably connected to the movable seat 7. A limiting plate 9 is provided on the base 1, and a tension spring 10 is provided between the limiting plate 9 and the movable seat 7. A distance sensor 11, specifically a UBS500 GM18N ultrasonic distance sensor 11, is provided on the other side of the limiting plate 9. A baffle 12, which works in conjunction with the distance sensor 11, is provided on the movable seat 7. When the annular forging 2 needs to be detected, the spring 10's rebound force causes the movable seat 7 to slide on the base 1 until the roller 8 contacts the annular forging 2. This point on the annular forging 2 is recorded as the zero-point positioning. Then, the ultrasonic distance sensor 11 is activated, and a turntable 3 is rotated on the base 1, causing the annular forging 2 to rotate relative to the base 1. When the inner diameter of the measurement point is smaller than the inner diameter of the zero-point positioning, the annular forging 2 will further contact the roller 8, causing the movable seat 7 to rotate. The baffle on seat 7 moves inward. When the inner diameter of the measuring point is larger than the inner diameter of the zero point positioning, the baffle on the movable seat 7 will move outward under the action of the spring force of tension spring 10. The movement of the baffle is recorded by ultrasonic ranging sensor 11, thereby forming the detection curve of the annular forging 2. By analyzing the highest and lowest points of the detection curve and the smoothness of the curve change, it is possible to quickly determine whether the roundness of the inner diameter of the annular forging 2 is qualified. At the same time, it is not necessary to manually measure the changes of multiple points, which improves the accuracy and efficiency of detecting the roundness of the annular forging 2 and reduces the labor intensity of manual labor.

[0021] Preferred, such as Figure 2 and Figure 3 As shown, a receiving plate 13 is slidably connected to the slider 4, which contacts the annular forging 2 or the clamping block 5. A limiting rod 14 is provided on one side of the receiving plate 13. The slider 4 is provided with a through hole 15 for the limiting rod 14 to pass through. The turntable 3 is provided with several limiting holes 16 that contact the limiting rod 14. A second spring 17 is provided between the receiving plate 13 and the slider 4. In the idle state, under the action of the rebound force of the second spring 17, the receiving plate 13 is driven to move upward, so that it contacts the clamping block 5, preventing the receiving plate 13 from sliding off the slide plate. At this time, the limiting rod 14 provided on the receiving plate 13 is located in the through hole 15 on the slider 4 and does not contact the limiting hole 16. The slider 4 can slide smoothly on the turntable 3, thereby adjusting the position of the two clamping blocks 5, realizing the fixation of annular forgings 2 of different sizes, and improving the utilization rate of the testing equipment. When the annular forging 2 is placed on the slide plate, it comes into contact with the receiving plate 13. The weight of the annular forging 2 itself is applied to the receiving plate 13, causing the receiving plate 13 to slide on the slider 4. This compresses the second spring 17 between the receiving plate 13 and the slider 4, causing the limiting rod 14 to enter the corresponding limiting hole 16. The resistance generated by the contact between the limiting rod 14 and the limiting hole 16, and between the limiting rod 14 and the through hole 15, restricts the slider 4 from sliding on the turntable 3, thereby fixing the annular forging 2 without additional operation to fix the slider 4. This simplifies the steps of fixing the annular forging 2 and improves the efficiency of fixing the annular forging 2.

[0022] Preferred, such as Figure 3 As shown, the end of the limiting rod 14 is provided with a first inclined surface 18 that contacts the limiting hole 16. The force generated by the first inclined surface 18 at the end of the limiting rod 14 contacting the limiting hole 16 causes the limiting rod 14 to move slightly, so that the limiting rod 14 can smoothly enter the limiting hole 16, avoiding the limiting rod 14 from deviating from the limiting hole 16 and thus preventing it from being unable to be smoothly inserted into the limiting hole 16, thereby further improving the stability of fixing the annular forging 2.

[0023] Preferred, such as Figure 2 and Figure 3 As shown, the end of the clamping block 5 is provided with a second inclined surface 19. When it is necessary to fix the annular forging 2, the annular forging 2 contacts the second inclined surface 19, and the resulting component force pushes the clamping block 5 to slide on the slider 4, so that the annular forging 2 can pass smoothly through the clamping block 5, thereby simplifying the steps of fixing the annular forging 2 and improving the efficiency of fixing the annular forging 2.

[0024] Preferred, such as Figure 3 As shown, the end of the clamping block 5 is provided with a friction part 20, which increases the friction between the clamping block 5 and the ring forging, improves the effect of the clamp in fixing the ring forging, ensures the stability of the ring forging 2 during the inspection process, and further improves the accuracy of the roundness of the ring forging 2.

[0025] Preferred, such as Figure 1 As shown, the detection mechanism consists of multiple groups, which are evenly arranged on the base 1. By setting multiple control groups, the error caused by a single detection mechanism is reduced, and the accuracy of detecting the roundness of the ring forging 2 is further improved.

[0026] Preferred, such as Figure 2 As shown, a bearing 21 is provided between the base 1 and the turntable 3 to reduce the friction between the base 1 and the turntable 3, improve the stability of the turntable 3 rotating on the base 1, and thus improve the accuracy of detecting the roundness of the annular forging 2.

[0027] Preferred, such as Figure 2As shown, the base 1 is provided with a drive motor 22, the movable end of the drive motor 22 is provided with a drive gear 23, and the end of the turntable 3 is provided with a toothed ring 24 that meshes with the drive gear 23, providing power for the turntable 3 to rotate on the base 1.

[0028] Example 1 This utility model provides a tool for detecting the roundness of ring forgings, such as... Figure 1 and Figure 2 As shown, when it is necessary to inspect ring forgings 2 of different sizes, slide the slider 4 on the turntable 3 first, and move the two clamping blocks 5 on the slider 4 together, so as to adapt to the fixing of ring forgings 2 of different sizes, break the limitation of one fixture for one size, reduce the manufacturing and storage costs of fixtures, and when changing ring forgings 2 of different sizes, there is no need to change the entire set of fixtures, only the positioning of the slider 4 needs to be adjusted, thereby greatly shortening the inspection time of different types of ring forgings 2 and improving the utilization rate of the inspection equipment; When it is necessary to fix the annular forging 2, the annular forging 2 is placed on the slide plate. By pressing the two clamping blocks 5, the first spring 6 between the clamping blocks 5 and the slide plate is compressed. At the same time, the movable seat 7 is pulled inward on the base 1, stretching the tension spring 10 provided between the limiting plate 9 and the movable seat 7, so that the annular forging 2 can pass smoothly through the clamping blocks 5 and the roller 8 and fall onto the turntable 3. Then, the external force is removed. The rebound force generated after the first spring 6 is compressed is applied to the annular forging 2 through the clamping blocks 5. Combined with its own weight, the movement of the annular forging 2 on the turntable 3 is restricted. In addition, the friction between the clamping blocks 5 and the annular forging 2, as well as the friction between the annular forging 2 and the turntable 3, restricts the rotation of the annular forging 2 relative to the turntable 3, thereby realizing the fixation of annular forgings 2 of different widths, further reducing the manufacturing and storage costs of the fixture, shortening the time for inspecting different types of annular forgings 2, and improving the utilization rate of the inspection equipment. After fixing the annular forging 2, remove the external force applied to the movable seat 7. Under the action of the spring 10's rebound force, the movable seat 7 slides on the base 1 until the roller 8 contacts the annular forging 2. Record this point on the annular forging 2 as the zero-point positioning. Then, turn on the ultrasonic ranging sensor 11 and rotate the turntable 3 on the base 1, causing the annular forging 2 to rotate relative to the base 1. When the inner diameter of the measuring point is smaller than the inner diameter of the zero-point positioning, the annular forging 2 will further contact the roller 8, causing the baffle on the movable seat 7 to move inward. When the measuring point... When the inner diameter is larger than the inner diameter of the zero-point positioning, the baffle on the movable seat 7 will move outward under the action of the spring force of the tension spring 10. The movement of the baffle is recorded by the ultrasonic ranging sensor 11, thereby forming the detection curve of the annular forging 2. By analyzing the highest and lowest points of the detection curve and the smoothness of the change of the detection curve, it can be quickly determined whether the roundness of the inner diameter of the annular forging 2 is qualified. At the same time, it is not necessary to manually measure the changes of multiple points, which improves the accuracy and efficiency of detecting the roundness of the annular forging 2 and reduces the labor intensity of manual labor.

[0029] Example 2 Based on Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, in the idle state, under the action of the rebound force of the second spring 17, the receiving plate 13 is driven to move upward, so that it contacts the clamping block 5, preventing the receiving plate 13 from sliding off the slide plate. At this time, the limiting rod 14 provided on the receiving plate 13 is located in the through hole 15 on the slider 4 and does not contact the limiting hole 16. The slider 4 can slide smoothly on the turntable 3, thereby adjusting the position of the two clamping blocks 5, realizing the fixation of ring forgings 2 of different sizes, and improving the utilization rate of the testing equipment. When it is necessary to fix the annular forging 2, the component force generated by the contact between the annular forging 2 and the second inclined surface 19 pushes the clamping block 5 to slide on the slider 4, so that the annular forging 2 can pass smoothly through the clamping block 5, thereby simplifying the steps of fixing the annular forging 2 and improving the efficiency of fixing the annular forging 2; in addition, the friction part 20 provided at the end of the clamping block 5 contacts the annular forging 2, increasing the friction between the clamping block 5 and the annular forging, improving the effect of the fixture in fixing the annular forging, ensuring the stability of the annular forging 2 during the inspection process, and further improving the accuracy of the roundness of the annular forging 2. When the annular forging 2 is placed on the slide plate, it contacts the receiving plate 13. The weight of the annular forging 2 is applied to the receiving plate 13, causing the receiving plate 13 to slide on the slider 4. This compresses the second spring 17 between the receiving plate 13 and the slider 4, causing the limiting rod 14 to enter the corresponding limiting hole 16. The resistance generated by the contact between the limiting rod 14 and the limiting hole 16, and between the limiting rod 14 and the through hole 15, restricts the slider 4 from sliding on the turntable 3, thus fixing the annular forging 2 without the need for additional... The operation of the fixed slider 4 simplifies the steps of fixing the ring forging 2 and improves the efficiency of fixing the ring forging 2. In addition, when the limiting rod 14 deviates slightly from the limiting hole 16, the first inclined surface 18 at the end of the limiting rod 14 contacts the limiting hole 16, and the resulting component force drives the limiting rod 14 to move slightly, so that the limiting rod 14 can smoothly enter the limiting hole 16, avoiding the limiting rod 14 deviating from the limiting hole 16 and thus preventing it from being unable to be smoothly inserted into the limiting hole 16, thereby further improving the stability of fixing the ring forging 2.
