A length measuring device for testing precision power components

Abstract

This invention belongs to the field of length measurement technology and discloses a length measuring device for precision power component testing. It includes a base and a tubular component, which is clamped by a clamp. The device also includes a shaping component, which is located on top of the base. The invention uses two plastic sleeves inserted into the tubular component. A pressure plate pushes the clay inside the plastic sleeves, causing the clay to move along the sleeves into the tubular component, filling the interior of the component. By pulling the two pressure components and the shaping component in the opposite direction, the two plastic sleeves are detached from the tubular component. The length inside the tubular component is then replicated using the plastic sleeves. Measuring this replicated length allows for accurate measurement, avoiding the problem of small diameter holes in the tubular component preventing the insertion of calipers for length measurement, thus ensuring the inspection and verification of component processing quality.

Description

Technical Field

[0001] This invention belongs to the field of length measurement technology, specifically a length measuring device for testing precision power components. Background Technology

[0002] Precision power components are core components or functional modules in power systems or equipment that perform critical functions such as power conversion, transmission, control, protection, or monitoring. They require high precision, high reliability, and high performance, and their design and manufacturing must strictly comply with electrical, mechanical, and environmental standards. The core of component length measurement is to accurately quantify the linear dimensions of the component (such as overall length, hole diameter, and spacing) to ensure that the processing results meet the design drawings, thereby guaranteeing assembly compatibility, functional reliability, and process stability.

[0003] In the length measurement of tubular components in power systems, traditional methods typically employ vernier calipers or micrometers. However, when the inner diameter of the middle section of the tubular component is smaller than that of both ends, and the length of the middle hole needs to be measured, the vernier calipers cannot easily reach inside due to the hole size limitation. This results in the inability to accurately measure the length of the middle pipe, thus affecting the inspection and verification of the component's processing quality. Therefore, a precision length measuring device for inspecting power components is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a length measuring device for precision power component testing, which solves the problem that existing tubular components have small apertures, making it difficult for traditional vernier calipers to penetrate them, thus preventing accurate measurement of the length of the middle pipe.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a length measuring device for precision power component testing, comprising a base and a tubular component, wherein the tubular component is clamped by a clamp, and further comprising:

[0006] A shaping component, which is symmetrically arranged on the top of the base;

[0007] A crossbeam is provided on the top of the shaping component;

[0008] A measuring component, which is fixedly mounted on a crossbeam;

[0009] The shaping component includes a first support frame fixed to the top of the base, and a crossbeam installed on the top of the first support frame;

[0010] A stabilizing sleeve is fixedly installed on the side of the first support frame. A support core rod is movably sleeved inside the stabilizing sleeve. A plastic sleeve is sleeved on the outside of the support core rod. A second magnet is fixedly installed at one end of the support core rod.

[0011] The plastic sleeve is filled with modeling clay and is in an unsaturated state. A pressure plate is movably fitted on the outside of the support core rod to push the modeling clay inside the plastic sleeve.

[0012] The two support core rods are kept coaxial with the tubular component.

[0013] Preferably, the inner wall of the pressure plate is provided with spring balls;

[0014] Initially, the putty inside the plastic sleeve is placed close to the pressure plate end, so that the outer diameter of the opposite ends of the two plastic sleeves is smaller than the inner diameter of the tubular component.

[0015] Preferably, the measuring component includes a scale plate fixed between the crossbeam and the base, and a high-definition camera is fixed on the crossbeam;

[0016] The plastic sleeve is located between the high-definition camera and the scale plate, and the high-definition camera and the plastic sleeve are kept horizontal.

[0017] Preferably, the scale plate is provided with a scale, and a first magnet is fixedly mounted on the support core rod;

[0018] When the support core rod moves in the reverse direction, the plastic sleeve detaches from the inside of the tubular component, the first magnet contacts the side of the first support frame, and the side of the second magnet remains at the same level as the scale reference point on the scale plate.

[0019] Preferably, a baffle is fixed between the crossbeam and the base, a second support frame is fixed on the baffle, and the stabilizing sleeve passes through the middle of the baffle.

[0020] Preferably, the pressure-applying component includes a threaded rod, with sliding frames movably mounted at both ends of the threaded rod, and a guide slide fixed to the inner wall of the crossbeam, wherein the threaded rod slides within the guide slide via the sliding frames;

[0021] The threaded rod is fitted with a transmission component on its external thread, and the transmission component is fixedly connected to the pressure plate via a connecting bracket.

[0022] Preferably, the pressure-applying components are symmetrically arranged at both ends of the crossbeam, and the threads of the two threaded rods are in opposite directions;

[0023] The two threaded rods are fixedly fitted with a connecting member at their opposite ends. The connecting member consists of four ring-shaped plates arranged at equal angles. The connecting plates at both ends engage with each other to form a circular tube.

[0024] Preferably, the positioning assembly includes a docking frame fixed to the bottom of the crossbeam, a drive wheel is provided at the bottom of the docking frame, a drive belt is provided on the outside of the drive wheel, and positioning rods are fixed at both ends of the drive belt.

[0025] Preferably, a connector is fixedly mounted on the bottom of the docking frame, and a guide rod is fixedly mounted on the connector, with the two positioning rods sliding outside the guide rod.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention involves inserting two plastic sleeves into a tubular component. A pressure plate pushes the clay inside the plastic sleeves, causing the clay to move along the plastic sleeves into the tubular component, filling the interior of the tubular component with the plastic sleeves and the clay. By pulling the two pressure components and the shaping components in the opposite direction, the two plastic sleeves can be detached from the interior of the tubular component. The length inside the tubular component is then replicated by the plastic sleeves, and measuring the replicated length enables accurate measurement. This avoids the problem of the tubular component having a small aperture, which prevents the vernier caliper from reaching inside to measure the length, thus ensuring the inspection and verification of the component's processing quality.

[0028] This invention involves filling the interior of a tubular component with a plastic sleeve and internal clay, while simultaneously detaching the plastic sleeve from the interior of the tubular component. A first magnet contacts the side of a first support frame, keeping the high-definition camera horizontal with the plastic sleeve. The high-definition camera captures images of the plastic sleeve replicating the interior of the tubular component, and the length of the replicated tubular component can be determined based on the captured images. The high-definition camera avoids contact measurement with the plastic sleeve, preventing deformation of the plastic sleeve and thus avoiding deviations in the measurement data.

[0029] This invention uses a clamp to pre-clamp tubular components. By pushing the positioning rod, the transmission belt rotates, causing the two positioning rods to move synchronously. The positioning rods slide along the guide rod to ensure their stability. During the movement, the two positioning rods clamp the two ends of the tubular component, placing the tubular component in the middle of the clamp. The clamp then tightens the tubular component, allowing the length inside the tubular component to be replicated through a plastic sleeve. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1 to 8 As shown, the present invention provides a length measuring device for testing precision power components, including a base 1 and a tubular component 7, the tubular component 7 being clamped by a clamp 6, and further comprising:

[0041] Shaping component 2 is symmetrically arranged on the top of base 1;

[0042] A crossbeam is provided on the top of the shaping component 2;

[0043] Measurement component 3 is fixedly mounted on the crossbeam;

[0044] The shaping component 2 includes a first support frame 27 fixed to the top of the base 1, and a crossbeam installed on the top of the first support frame 27;

[0045] A stabilizing sleeve 28 is fixedly installed on the side of the first support frame 27. A support core rod 21 is movably sleeved inside the stabilizing sleeve 28. A plastic sleeve 25 is sleeved on the outside of the support core rod 21. A second magnet 24 is fixedly installed at one end of the support core rod 21.

[0046] The plastic sleeve 25 is filled with clay and is in an unsaturated state. The support core rod 21 is movably fitted with a pressure plate 23 to push the clay inside the plastic sleeve 25.

[0047] The two support core rods 21 are coaxial with the tubular component 7;

[0048] The inner wall of the pressure plate 23 is provided with spring balls;

[0049] The putty inside the initial plastic sleeve 25 is close to the end of the pressure plate 23, so that the outer diameter of the opposite ends of the two plastic sleeves 25 is smaller than the inner diameter of the tubular component 7.

[0050] The clamp 6 is used to hold the tubular component 7, which is located in the middle of the clamp 6 under the action of the positioning component 5. By pushing the two shaping components 2 and the pressure application component 4 to move synchronously towards the tubular component 7, since the outer diameter of the opposite ends of the two plastic sleeves 25 is smaller than the inner diameter of the tubular component 7, it is ensured that the plastic sleeves 25 can be properly inserted into the tubular component 7. They are attracted to each other by the second magnets 24 at the opposite ends of the two support core rods 21. Rotating the pressure application component 4 causes the two second magnets 24 to move relative to each other along the support core rods 21. The pressure plate 23 pushes the clay inside the plastic sleeve 25, and at the same time, the spring ball bearings on the inner wall of the pressure plate 23 reduce the friction between the pressure plate 23 and the plastic sleeve 25. The clay moves along the plastic sleeve 25 into the tubular component 7, filling the interior of the tubular component 7 with the plastic sleeve 25 and the clay inside. At this time, by pulling the two pressure components 4 in the opposite direction to the shaping component 2, the two plastic sleeves 25 can be detached from the interior of the tubular component 7. The length of the two plastic sleeves 25 is measured by the measuring component 3. The length of the middle part of the inner wall of the tubular component 7 can be measured based on the length of the plastic sleeves 25. In this process, the length inside the tubular component 7 is replicated by the plastic sleeves 25. Measuring the replicated length can achieve accurate measurement and avoid the small diameter of the tubular component 7, which makes it impossible for the vernier caliper to reach into it to measure the length. This ensures the inspection and verification of the processing quality of the parts.

[0051] Furthermore, as the inner diameter of the tubular component gradually increases from one end to the other, a plastic sleeve 25 can be used to enter the tubular component from the end with the larger aperture, thus replicating the internal length through the plastic sleeve 25.

[0052] like Figure 1 and Figure 2 As shown, the measuring component 3 includes a scale plate 32 fixed between the crossbeam and the base 1, and a high-definition camera device 31 fixed on the crossbeam;

[0053] The plastic sleeve 25 is located between the high-definition camera device 31 and the scale plate 32, and the high-definition camera device 31 and the plastic sleeve 25 are kept horizontal;

[0054] The scale plate 32 is provided with a scale, and the first magnet 22 is fixedly mounted on the support core rod 21;

[0055] When the support core rod 21 moves in the opposite direction, the plastic sleeve 25 detaches from the inside of the tubular component 7, the first magnet 22 contacts the side of the first support frame 27, and the side of the second magnet 24 remains at the same level as the scale reference point on the scale plate 32.

[0056] The plastic sleeve 25 and the clay inside are filled into the interior of the tubular component 7. At the same time, the plastic sleeve 25 is detached from the interior of the tubular component 7. The first magnet 22 contacts the side of the first support frame 27, so that the high-definition camera 31 and the plastic sleeve 25 are kept horizontal. The high-definition camera 31 captures the interior of the tubular component 7 through the plastic sleeve 25. The length of the interior of the tubular component 7 that the plastic sleeve 25 replicates can be determined based on the captured image. The high-definition camera 31 avoids contact measurement with the plastic sleeve 25, and avoids deformation of the plastic sleeve 25, which would lead to deviations in the measurement data.

[0057] like Figure 2 and Figure 3 As shown, a baffle 212 is fixed between the crossbeam and the base 1, and a second support frame 211 is fixed on the baffle 212. The stabilizing sleeve 28 passes through the middle of the baffle 212.

[0058] The pressure component 4 pushes the support core rod 21 into the tubular component 7, causing the plastic sleeve 25 to extend into the tubular component 7. Meanwhile, the support core rod 21 moves along the stabilizing sleeve 28. The stabilizing sleeve 28 ensures the stability of the support core rod 21 and the plastic sleeve 25, preventing the support core rod 21 from tilting due to gravity caused by the plastic sleeve 25 and the clay inside being located at one end of the support core rod 21. This would affect the accuracy of the plastic sleeve 25 replication and the accuracy of length measurement.

[0059] like Figures 3-6 As shown, the pressure application assembly 4 includes a threaded rod 41, with sliding frames 43 movably mounted at both ends of the threaded rod 41, and a guide slide 45 fixedly mounted on the inner wall of the crossbeam. The threaded rod 41 slides within the guide slide 45 through the sliding frames 43.

[0060] The threaded rod 41 is fitted with a transmission component 42 on its external thread, and the transmission component 42 is fixedly connected to the pressure plate 23 through the connecting bracket 26;

[0061] The pressure-applying components 4 are symmetrically arranged at both ends of the crossbeam, and the threads of the two threaded rods 41 are opposite in direction;

[0062] Two threaded rods 41 are fixedly fitted with mating parts 44 at their opposite ends. The mating parts 44 are composed of four ring-shaped plates set at equal angles. The plates of the mating parts 44 at both ends engage with each other to form a circular tube.

[0063] By pushing the two threaded rods 41 to move relative to each other, the threaded rods 41 slide along the guide slide 45 through the sliding frame 43, and drive the shaping component 2 to move synchronously relative to each other and extend into the tubular component 7. During the relative movement of the two threaded rods 41, the two mating parts 44 engage with each other to form a round tube, and the two second magnets 24 contact each other. By rotating the round tube, the two threaded rods 41 rotate synchronously. Since the thread directions of the two threaded rods 41 are opposite, the two transmission parts 42 and the shaping component 2 move synchronously relative to each other along the threaded rods 41, ensuring that the two plastic sleeves 25 enter the tubular component 7 synchronously, so that the interior of the tubular component 7 can be replicated through the plastic sleeves 25.

[0064] like Figure 8 As shown, the positioning component 5 includes a docking frame 51 fixed to the bottom of the crossbeam, a transmission wheel 52 is provided at the bottom of the docking frame 51, a transmission belt 55 is provided on the outside of the transmission wheel 52, and positioning rods 54 are fixed at both ends of the transmission belt 55.

[0065] A connector 53 is fixedly mounted on the bottom of the docking frame 51, and a guide rod 56 is fixedly mounted on the connector 53. Two positioning rods 54 slide outside the guide rod 56.

[0066] The tubular component 7 is pre-clamped by the clamp 6. The transmission belt 55 is rotated by pushing the positioning rod 54, so that the two positioning rods 54 move synchronously. The positioning rods 54 slide along the guide rod 56 to ensure the stability of the positioning rods 54. During the movement, the two positioning rods 54 are clamped at both ends of the tubular component 7, so that the tubular component 7 is located in the middle of the clamp 6. The clamp 6 is then used to clamp the tubular component 7, and the length inside the tubular component 7 can be replicated by the plastic sleeve 25.

[0067] Working principle and usage process of this invention:

[0068] The tubular component 7 is pre-clamped by the clamp 6. The transmission belt 55 is rotated by pushing the positioning rod 54, so that the two positioning rods 54 move synchronously. The positioning rods 54 slide along the guide rod 56 to ensure the stability of the positioning rods 54. During the movement, the two positioning rods 54 clamp the two ends of the tubular component 7, so that the tubular component 7 is located in the middle of the clamp 6. Then the clamp 6 clamps the tubular component 7.

[0069] By pushing the two threaded rods 41 to move relative to each other, the threaded rods 41 slide along the guide slide 45 through the sliding frame 43, and drive the shaping assembly 2 to move synchronously relative to each other and extend into the tubular component 7. During the relative movement of the two threaded rods 41, the two mating parts 44 engage with each other to form a round tube, and the two second magnets 24 contact each other. By rotating the round tube, the two threaded rods 41 rotate synchronously. Since the thread directions of the two threaded rods 41 are opposite, the two transmission parts 42 and the connecting frame 26 move synchronously relative to each other along the threaded rods 41.

[0070] The pressure plate 23 pushes the clay inside the plastic sleeve 25, and the clay moves along the plastic sleeve 25 into the tubular component 7, so that the plastic sleeve 25 and the clay inside it fill the interior of the tubular component 7. At this time, by pulling the two pressure components 4 and the shaping component 2 in the opposite direction, the two plastic sleeves 25 can be separated from the interior of the tubular component 7.

[0071] The plastic sleeve 25 and the clay inside are filled into the interior of the tubular component 7. At the same time, the plastic sleeve 25 is detached from the interior of the tubular component 7. The first magnet 22 contacts the side of the first support frame 27, so that the high-definition camera 31 and the plastic sleeve 25 are kept horizontal. The high-definition camera 31 takes pictures of the plastic sleeve 25 replicating the interior of the tubular component 7. The length of the plastic sleeve 25 replicating the interior of the tubular component 7 can be determined from the pictures.
