Description

Technical Field

[0001] This utility model relates to the technical field of slip ring testing devices, and in particular to a positioning device for slip ring testing. Background Technology

[0002] In batch quality inspection during slip ring production, dimensional deviations on the outer circumferential surface (such as local bulges, depressions, or uneven diameter) are core quality indicators, directly affecting the assembly accuracy and operational reliability of the slip ring and its supporting components. Traditional external clamping methods, due to fixture obstruction, can only cover a portion of the slip ring's outer wall. Hidden defects (such as small-area depressions or edge dimensional deviations) are easily missed, leading to missed inspections or misjudgments, severely reducing the accuracy and reliability of the inspection. If comprehensive inspection is required, the slip ring position must be adjusted multiple times or different sizes of fixtures must be replaced, which is cumbersome and time-consuming, failing to meet the high efficiency requirements of batch inspection.

[0003] When slip ring testing devices are in use, traditional slip ring testing devices in batch quality inspection scenarios usually adopt a fixing method of clamping from the outside of the slip ring. That is, clamping force is applied from the outside of the slip ring through a fixture or positioning structure to achieve positioning. Although this method can achieve basic fixation of the slip ring, it has significant technical defects: because the fixture directly occupies the physical space of the outer wall of the slip ring, the detection mechanism (such as contact sensor, probe, etc.) cannot directly contact the entire area of ​​the outer circumference of the slip ring, resulting in a large number of blind spots during detection, making it difficult to perform a complete 360° full circumferential scan of the outer wall of the slip ring.

[0004] Therefore, to address the problem of inconvenience in fully inspecting the outer wall of the slip ring during batch quality testing, a positioning device for slip ring testing can be designed. When using this device, the operator first places the slip ring to be tested on the outside of the two sets of arc-shaped clamps above the rotating seat. At this time, the bottom sides of the slip ring are supported by the support arc plates fixed to the bottom of the outer wall of the arc-shaped clamps, providing initial positioning. Then, the adjustment mechanism is activated to smoothly expand the arc-shaped clamps outwards. The outer wall of the arc-shaped clamps is covered with a flexible material, which conforms to the inner wall of the slip ring during clamping and prevents scratches. The device achieves precise clamping of the inner wall of the slip ring through the symmetrical contact of two sets of arc-shaped clamps, ensuring that the slip ring and the rotating seat are coaxial. After clamping, the front end of the detection mechanism contacts the outer wall of the slip ring, and then drives the rotating seat to rotate, thereby driving the clamped slip ring to rotate synchronously. At this time, the detection mechanism can detect dimensional deviations on the outer circumference of the slip ring. In summary, through the coordinated design of mechanical structure and electronic control, this device can achieve comprehensive detection of the outer wall of the slip ring, realizing the automation, precision and efficiency of slip ring testing, and is suitable for batch quality inspection in the slip ring production process. Utility Model Content

[0005] To overcome the problem that traditional slip ring testing devices typically use a clamping method from the outside of the slip ring during use, the testing mechanism cannot directly contact the entire area of ​​the slip ring's outer circumference because the clamp directly occupies the physical space of the slip ring's outer wall. Therefore, it is inconvenient to achieve comprehensive testing of the slip ring's outer wall when used in batch quality inspection scenarios.

Then, the adjustment mechanism is activated to drive the two arc-shaped clamps to expand smoothly outward. The outer wall of the arc-shaped clamps is covered with a flexible material, which can fit the inner wall of the slip ring during clamping and avoid scratches. Finally, the symmetrical contact of the two sets of arc-shaped clamps achieves precise clamping of the inner wall of the slip ring, ensuring that the slip ring and the rotating seat are coaxial. After clamping is completed, the front end of the detection mechanism contacts the outer wall of the slip ring, and then drives the rotating seat to rotate, thereby driving the clamped slip ring to rotate synchronously. At this time, the detection mechanism can detect the dimensional deviations on the outer circumference of the slip ring. In summary, this device, through the coordinated design of mechanical structure and electronic control, can achieve the effect of comprehensive detection of the outer wall of the slip ring, realizing the automation, accuracy and efficiency of slip ring testing, and is suitable for batch quality inspection in the slip ring production process.

[0014] The beneficial effects of this utility model are:

[0015] 1. When using this slip ring testing device, the operator first places the slip ring to be tested on the outside of the two sets of arc-shaped clamps above the rotating seat. At this time, the bottom sides of the slip ring are supported by the support arc plates fixed to the bottom of the outer wall of the arc-shaped clamps, which plays a preliminary positioning role. Then, the adjustment mechanism is activated to drive the two arc-shaped clamps to expand smoothly outward. The outer wall of the arc-shaped clamps is covered with a flexible material, which can fit the inner wall of the slip ring during clamping and avoid scratches. Finally, the symmetrical contact of the two sets of arc-shaped clamps achieves precise clamping of the inner wall of the slip ring, ensuring that the slip ring and the rotating seat are coaxial. After clamping is completed, the front end of the detection mechanism contacts the outer wall of the slip ring, and then drives the rotating seat to rotate, thereby driving the clamped slip ring to rotate synchronously. At this time, the detection mechanism can detect the dimensional deviations on the outer circumference of the slip ring. In summary, this device, through the coordinated design of mechanical structure and electronic control, can achieve the effect of comprehensive detection of the outer wall of the slip ring, realizing the automation, accuracy and efficiency of slip ring testing, and is suitable for batch quality inspection in the slip ring production process.

[0016] 2.

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

[0025] Please see Figure 1 and Figure 2 This utility model provides an embodiment: a positioning device for slip ring testing, including a testing body 1, a rotatable rotating seat 2 embedded in the top of the testing body 1, an adjustment mechanism provided in the hollow inner cavity of the rotating seat 2, and two sets of arc-shaped clamps 3. Two sets of arc-shaped clamps 3 are symmetrically arranged above the rotating seat 2. The bottom of the arc-shaped clamps 3 on both sides are fixedly connected to the top of the adjustment mechanism, and a supporting arc plate 4 is fixedly connected to the bottom of the outer wall of the arc-shaped clamps 3. A detection mechanism is provided on one side of the top of the testing body 1.

[0026] Please see Figure 2 and Figure 3 The adjustment mechanism includes an adjustment motor 5, a bidirectional lead screw 6, and an adjustment slider 7. The adjustment motor 5 is fixedly installed on one side of the hollow inner cavity of the rotating seat 2. The output end of the adjustment motor 5 is connected to the bidirectional lead screw 6. The end of the bidirectional lead screw 6 is rotatably connected to the inner wall of the hollow inner cavity of the rotating seat 2. The adjustment sliders 7 are symmetrically sleeved on the outer walls of both sides of the bidirectional lead screw 6. The bottom of the two arc-shaped clamps 3 on both sides is fixedly connected to the top of the two adjustment sliders 7 respectively. When the adjustment motor 5 is started, the output end of the adjustment motor 5 drives the bidirectional lead screw 6 to rotate. Since the thread directions of the two outer walls of the bidirectional lead screw 6 are opposite, the two adjustment sliders 7 sleeved on it will move synchronously in opposite directions with the rotation of the lead screw, thereby driving the two arc-shaped clamps 3 fixedly connected to the top of the adjustment sliders 7 to expand smoothly outward.

[0027] Please see Figure 4 and Figure 5 An electrically controlled telescopic rod 8 is fixedly installed on one side of the top of the test body 1. A guide groove 9 is opened on one side of the top of the test body 1. A guide block 10 is fixedly connected to the telescopic end of the electrically controlled telescopic rod 8. The inner cavity of the guide block 10 slides into the guide groove 9. When the electrically controlled telescopic rod 8 is activated, the telescopic end of the electrically controlled telescopic rod 8 pushes the guide block 10, which is fixedly connected to it, to slide along the guide groove 9 opened on the top of the test body 1. At the same time, it drives the detection mechanism in the support frame 11 to move closer to the slip ring. The top of the guide block 10 is fixedly connected to the support frame 11. A support column 12 is fixedly connected inside the support frame 11. A sliding block 13 is slidably sleeved on the side wall of the support column 12. An electrically controlled lifting rod 14 is fixedly installed on the top of the support frame 11. The telescopic end of the electrically controlled lifting rod 14 is fixedly connected to one side of the sliding block 13. When the electrically controlled lifting rod 14 is activated, the telescopic end of the electrically controlled lifting rod 14 drives the sliding block 13, which is fixedly connected to it, to slide along the support column 12 in the support frame 11. The movement of the sliding block 13 synchronously drives the fixed cylinder 15 and the front detection mechanism to rise and fall.

[0028] Please see Figure 5and Figure 6 The testing mechanism includes a fixed cylinder 15, a telescopic cavity 16, a telescopic column 17, a limiting ring 18, and a sliding bead 19. The fixed cylinder 15 is fixedly connected to the other side of the sliding block 13. A telescopic cavity 16 is formed inside the fixed cylinder 15. A telescopic column 17 is slidably mounted through the end of the fixed cylinder 15. A sliding bead 19 is rotatably mounted on the outer end of the telescopic column 17. A limiting ring 18 is fixedly connected to the inner end of the telescopic column 17. The outer wall size of the limiting ring 18 is adapted to the inner wall size of the telescopic cavity 16. When the sliding bead 19 at the front end of the testing mechanism contacts the outer wall of the sliding ring, the telescopic column 17 is subjected to the reaction force of the outer wall of the sliding ring towards the fixed cylinder 15. The telescopic cavity 16 of the fixed cylinder 15 contracts. At this time, the limiting ring 18, which is fixedly connected to the inner end of the telescopic column 17, slides along the inner wall of the telescopic cavity 16. The detection mechanism also includes an adjusting spring 20, a pressure sensor 21, and a contact rubber ball 22. The adjusting spring 20 is fixedly connected between the limiting ring 18 and the telescopic cavity 16. One end of the adjusting spring 20 is fixedly connected to the inner wall of the limiting ring 18, and the other end of the adjusting spring 20 is fixedly connected to the inner wall of the telescopic cavity 16. The pressure sensor 21 is fixedly installed at the inner end of the telescopic column 17, and the contact rubber ball 22 is fixedly connected to the inner wall of the pressure sensor 21. Simultaneously, compression... An adjusting spring 20 is placed between the limiting ring 18 and the bottom of the telescopic cavity 16. The elastic force of the adjusting spring 20 keeps the sliding ball 19 in close contact with the outer wall of the sliding ring. The pressure sensor 21 fixed to the inner end of the telescopic column 17 converts the contact pressure on the sliding ball 19 into an electrical signal by contacting the rubber ball 22 with the bottom of the telescopic cavity 16. A rotary motor 23 is fixedly installed on the inner side of the top of the test body 1. The output end of the rotary motor 23 is fixedly connected to the bottom of the rotating seat 2. An operator 24 is fixedly installed on the side wall of the test body 1. A display 25 is fixedly installed on the other side of the top of the test body 1. Start-up. The rotating motor 23 on the inner top of the test body 1 drives the rotating seat 2 to rotate, which in turn drives the clamped slip ring to rotate synchronously. At this time, the sliding ball 19 of the detection mechanism is always in close contact with the outer circumference of the slip ring. If there is a dimensional deviation on the outer circumference of the slip ring, the contact pressure of the sliding ball 19 will be transmitted to the pressure sensor 21 through the telescopic column 17. The pressure sensor 21 transmits the pressure change data to the operator 24 on the side wall of the test body 1 in real time, and displays it in numerical or curve form through the display 25 on the other side of the top. The operator can intuitively judge whether the outer circumference of the slip ring is qualified.

[0029] When using this slip ring testing device, the working principle of the slip ring testing positioning device mainly revolves around the precise clamping of the slip ring, multi-dimensional detection and data feedback. The specific process is as follows: The operator first places the slip ring to be tested on the outside of the two sets of arc-shaped clamps 3 above the rotating seat 2. At this time, the bottom sides of the slip ring are supported by the support arc plates 4 fixed at the bottom of the outer wall of the arc clamp 3, which plays a preliminary positioning role.

[0030] Then, the adjusting motor 5 in the adjusting mechanism is started. The output end of the adjusting motor 5 drives the bidirectional lead screw 6 to rotate. Since the threads on the outer walls of the two sides of the bidirectional lead screw 6 are opposite, the two adjusting sliders 7 sleeved on it will move synchronously in opposite directions as the lead screw rotates. This will drive the two arc-shaped clamps 3 fixedly connected to the top of the adjusting sliders 7 to expand smoothly outward. The outer wall of the arc-shaped clamps 3 is covered with a flexible material, which can fit against the inner wall of the slip ring during the clamping process and avoid scratches. Finally, the symmetrical contact of the two sets of arc-shaped clamps 3 achieves precise clamping of the inner wall of the slip ring, ensuring that the slip ring and the rotating seat 2 are coaxial.

[0031] After clamping is completed, the electrically controlled telescopic rod 8 on the top side of the test machine body 1 is activated. The telescopic end of the electrically controlled telescopic rod 8 pushes the guide block 10, which is fixedly connected to it, to slide along the guide groove 9 opened on the top of the test machine body 1 (the cross-sectional shape of the guide groove 9 matches that of the guide block 10 to ensure sliding stability). The support frame 11 fixed on the top of the guide block 10 moves accordingly, driving the detection mechanism inside the support frame 11 to move closer to the slip ring.

[0032] When the sliding bead 19 at the front end of the detection mechanism contacts the outer wall of the slip ring, the telescopic column 17 retracts into the telescopic cavity 16 of the fixed cylinder 15 due to the reaction force of the outer wall of the slip ring. At this time, the limiting ring 18, which is fixedly connected to the inner end of the telescopic column 17, slides along the inner wall of the telescopic cavity 16 (the outer wall of the limiting ring 18 and the inner wall of the telescopic cavity 16 are fitted with a clearance to reduce sliding friction). At the same time, the adjusting spring 20 between the limiting ring 18 and the bottom of the telescopic cavity 16 is compressed. The elastic force of the adjusting spring 20 keeps the sliding bead 19 in close contact with the outer wall of the slip ring. The pressure sensor 21 fixed at the inner end of the telescopic column 17 converts the contact pressure on the sliding bead 19 into an electrical signal by contacting the rubber ball 22 with the bottom of the telescopic cavity 16.

[0033] Subsequently, a rotational test of the outer circumference of the slip ring is performed. The rotating motor 23 on the inner side of the top of the test machine body 1 is started. The output end of the rotating motor 23 drives the rotating seat 2 to rotate, thereby driving the clamped slip ring to rotate synchronously. At this time, the sliding ball 19 of the testing mechanism is always in close contact with the outer circumference of the slip ring. If there is a dimensional deviation on the outer circumference of the slip ring (such as protrusions, depressions or uneven diameter), the contact pressure of the sliding ball 19 will be transmitted to the pressure sensor 21 through the telescopic column 17. The pressure sensor 21 transmits the pressure change data to the operator 24 on the side wall of the test machine body 1 in real time, and displays it in numerical or curve form through the display 25 on the other side of the top. The operator can intuitively judge whether the outer circumference of the slip ring is qualified.

[0034] In addition, to comprehensively detect the dimensions of different heights on the outer circumference of the slip ring, the electrically controlled lifting rod 14 at the top of the support frame 11 is activated. The telescopic end of the electrically controlled lifting rod 14 drives the sliding block 13, which is fixedly connected to it, to slide along the support column 12 inside the support frame 11 (the support column 12 is a smooth round rod, and the inner wall of the sliding block 13 is equipped with a linear bearing to reduce friction). The movement of the sliding block 13 synchronously drives the fixed cylinder 15 and the front detection mechanism to rise and fall, thereby adjusting the contact height between the sliding ball 19 and the outer circumference of the slip ring, so as to achieve accurate detection of different longitudinal positions on the outer circumference of the slip ring. During the detection process, the operator 24 can control the start and stop of the electrically controlled telescopic rod 8, the electrically controlled lifting rod 14 and the rotation motor 23 and adjust the parameters to ensure the automation and controllability of the detection process.

[0035] In summary, this slip ring testing positioning device achieves efficient and accurate slip ring testing through the following innovative designs: First, the adjusting motor 5 drives the bidirectional lead screw 6 to achieve symmetrical expansion of the two sets of arc-shaped clamps 3, which can quickly adapt to the clamping requirements of slip rings with different inner diameters. The flexible material of the outer wall of the arc-shaped clamps 3 avoids scratching the inner wall of the slip ring during clamping, balancing testing efficiency and product protection. Second, the rotating motor 23 drives the slip ring to rotate, and combined with the electrically controlled lifting rod 14 to adjust the height of the testing mechanism, it can perform 360° full circumferential and longitudinal multi-height dimensional testing on the outer circumference of the slip ring, covering a more comprehensive testing range. Third, the testing mechanism extends through the sliding ball 19. The structure of the reduced column 17-pressure sensor 21 converts the dimensional deviation of the outer circumference of the slip ring into pressure data. Combined with the elastic compensation of the adjusting spring 20, it ensures the detection sensitivity and accuracy of the pressure sensor 21. Fourthly, the operator 24 integrates control functions, which can start the detection process and adjust parameters with one click. The display 25 displays the pressure data in real time, which makes it easy for operators to quickly judge the quality of the slip ring and improve the detection efficiency. In summary, through the coordinated design of mechanical structure and electronic control, this device can achieve the effect of comprehensive detection of the outer wall of the slip ring, realizing the automation, accuracy and efficiency of slip ring testing, and is suitable for batch quality inspection in the slip ring production process.

[0036] Through the above steps, when using this slip ring testing device, the operator first places the slip ring to be tested on the outside of the two sets of arc-shaped clamps 3 above the rotating seat 2. At this time, the bottom sides of the slip ring are supported by the support arc plates 4 fixed to the bottom of the outer wall of the arc-shaped clamps 3, which plays a preliminary positioning role. Then, the adjustment mechanism is activated to drive the two arc-shaped clamps 3 to expand smoothly outward. The outer wall of the arc-shaped clamps 3 is covered with a flexible material, which can fit the inner wall of the slip ring and avoid scratches during the clamping process. Finally, the symmetrical contact of the two sets of arc-shaped clamps 3 achieves precise clamping of the inner wall of the slip ring, ensuring that the slip ring and the rotating seat 2 are coaxial. After clamping is completed, the front end of the detection mechanism contacts the outer wall of the slip ring. Then, the rotating seat 2 is driven to rotate, which in turn drives the clamped slip ring to rotate synchronously. At this time, the detection mechanism can detect the dimensional deviations on the outer circumference of the slip ring. In summary, through the coordinated design of mechanical structure and electronic control, this device can achieve a comprehensive detection effect on the outer wall of the slip ring, realizing the automation, precision and efficiency of slip ring testing, and is suitable for batch quality inspection in the slip ring production process.
