Description

Technical Field

[0001] The invention belongs to the technical field of length measurement, in particular to a length measuring device for detecting precision electric components. Background Art

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

[0003] Traditionally, vernier calipers or micrometers are used to measure the length of tubular power components. However, when the middle inner diameter of a tubular power component is smaller than the inner diameters at both ends and the length of the middle aperture needs to be measured, the vernier caliper is difficult to insert due to the limited aperture size. This makes it impossible to accurately measure the middle pipe length, which affects the inspection and verification of the component processing quality. Therefore, a length measurement device for precision power component inspection is proposed. Summary of the Invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a length measuring device for detecting precision electrical components, which solves the problem that the aperture of existing tubular components is small and traditional vernier calipers are difficult to insert into the interior, resulting in the inability to accurately measure the length of the middle pipe.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a length measuring device for detecting precision electrical components, comprising a base and a tubular component, wherein the tubular component is clamped by a clamp, and further comprising:

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

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

[0008] A measuring assembly, wherein the measuring assembly is fixedly mounted on the crossbeam;

[0009] Wherein, the shaping assembly includes a first support frame fixedly mounted on the top of the base, and the crossbeam is mounted on the top of the first support frame;

[0010] A stabilizing sleeve is fixedly mounted on the side of the first support frame, a supporting core rod is movably mounted inside the stabilizing sleeve, a plastic sleeve is mounted outside the supporting core rod, and a second magnet is fixedly mounted on one end of the supporting core rod;

[0011] The interior of the plastic sleeve is filled with plasticine, and the plastic sleeve is in an unsaturated state. The outer movable sleeve of the supporting core rod is provided with a pressure plate for pushing the plasticine in the plastic sleeve;

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

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

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

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

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

[0017] Preferably, the scale plate is provided with scales, and the supporting core rod is fixed with a first magnet;

[0018] When the supporting core rod moves in the reverse direction, the plastic sleeve is separated from the interior of the tubular component, the first magnet contacts the side of the first supporting frame, and the side of the second magnet maintains a horizontal plane with the scale reference point on the scale plate.

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

[0020] Preferably, the pressure assembly includes a threaded rod, with sliding brackets movably mounted on both ends of the threaded rod, and a guide bracket fixedly mounted on the inner wall of the crossbeam, and the threaded rod slides in the guide bracket via the sliding bracket;

[0021] The external thread sleeve of the threaded rod is provided with a transmission member, and the transmission member is fixedly connected to the pressure plate through a connecting frame.

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

[0023] The opposite ends of the two threaded rods are fixed with docking pieces, which are composed of four ring-shaped rulers arranged at equal angles. The rulers of the docking pieces at both ends are engaged with each other to form a circular tube.

[0024] Preferably, the positioning assembly includes a docking frame fixedly mounted on the bottom of the beam, a transmission wheel is provided at the bottom of the docking frame, a transmission belt is provided for the external transmission of the transmission wheel, and positioning rods are fixedly mounted at both ends of the transmission belt.

[0025] Preferably, a connecting piece is fixedly mounted on the bottom of the docking frame, a guide rod is fixedly mounted on the connecting piece, and the two positioning rods slide outside the guide rod.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention extends two plastic sleeves into the tubular component, pushes the plasticine in the plastic sleeves through a pressure plate, causes the plasticine to move along the plastic sleeves into the tubular component, and fills the interior of the tubular component with the plastic sleeves and the plasticine inside. The two pressure components and the shaping components are pulled in opposite directions to move in opposite directions, so that the two plastic sleeves can be separated from the interior of the tubular component, and the length of the tubular component inside can be replicated through the plastic sleeves. Accurate measurement can be achieved by measuring the replicated length, avoiding the problem that the vernier caliper cannot be inserted into the tubular component due to the small aperture, thereby ensuring the inspection and verification of the component processing quality.

[0028] The present invention fills the interior of a tubular component with a plastic sleeve and the plasticine inside, while the plastic sleeve is separated from the interior of the tubular component. The first magnet contacts the side of the first support frame, so that the high-definition camera device and the plastic sleeve are kept level. The high-definition camera device captures the interior of the tubular component replicated by the plastic sleeve, and the length of the tubular component replicated by the plastic sleeve can be determined based on the captured image. The high-definition camera device avoids contact measurement of the plastic sleeve, thereby preventing deformation of the plastic sleeve and deviation of the measurement data.

[0029] The present invention pre-clamps the tubular component through a clamp, and drives the transmission belt to rotate by pushing the positioning rod, so that the two positioning rods move synchronously. The positioning rods slide along the guide rod to ensure the stability of the positioning rods. During the movement, the two positioning rods are clamped at both ends of the tubular component, so that the tubular component is located in the middle of the clamp. The tubular component is then clamped by the clamp, and the length inside the tubular component can be replicated through the plastic sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts 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 detecting precision electric components, comprising a base 1 and a tubular component 7, wherein the tubular component 7 is clamped by a clamp 6, and further comprising:

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

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

[0043] Measuring component 3, measuring component 3 is fixed on the beam;

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

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

[0046] The interior of the plastic sleeve 25 is filled with plasticine, and the plastic sleeve 25 is in an unsaturated state. The outer movable sleeve supporting the core rod 21 is provided with a pressure plate 23 for pushing the plasticine in the plastic sleeve 25;

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

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

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

[0050] The clamp 6 is used to clamp the tubular component 7, and the tubular component 7 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 component 4 to move synchronously toward the tubular component 7, since the outer diameters of the opposite ends of the two plastic sleeves 25 are initially smaller than the inner diameter of the tubular component 7, it is ensured that the plastic sleeve 25 can normally extend into the tubular component 7, and the second magnets 24 at the opposite ends of the two supporting core rods 21 are attracted to each other. The rotation of the pressure component 4 drives the two second magnets 24 to move relative to each other along the supporting core rod 21, and the plasticine in the plastic sleeve 25 is pushed by the pressure plate 23. At the same time, the friction between the pressure plate 23 and the plastic sleeve 25 is reduced by the spring ball on the inner wall of the pressure plate 23. The plasticine moves along the plastic sleeve 25 into the tubular component 7, so that the plastic sleeve 25 and the plasticine inside fill the interior of the tubular component 7. At this time, by pulling the two pressure components 4 and the shaping component 2 in opposite directions, the two plastic sleeves 25 can be separated from the interior of the tubular component 7. The length of the two plastic sleeves 25 is measured by the measuring component 3. According to the length of the plastic sleeve 25, the length of the middle part of the inner wall of the tubular component 7 can be measured. In this process, the length inside the tubular component 7 is replicated by the plastic sleeve 25. Measuring the replicated length can achieve accurate measurement, avoiding the problem that the vernier caliper cannot be inserted into the tubular component 7 due to the small diameter of the tubular component 7 to measure the length, thereby ensuring the inspection and verification of the component processing quality;

[0051] Furthermore, when the inner diameter of the tubular component gradually increases from one end to the other, a plastic sleeve 25 is passed into the tubular component from the end with a larger aperture, and the inner length can be replicated through the plastic sleeve 25.

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

[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 scales, and the supporting core rod 21 is fixed with a first magnet 22;

[0055] When the supporting core rod 21 moves in the reverse direction, the plastic sleeve 25 is separated 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 maintains a horizontal plane with the scale reference point on the scale plate 32.

[0056] The interior of the tubular component 7 is filled with the plastic sleeve 25 and the plasticine inside. At the same time, the plastic sleeve 25 is separated 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 device 31 and the plastic sleeve 25 are kept level. The high-definition camera device 31 is used to photograph the interior of the tubular component 7 replicated by the plastic sleeve 25. The length of the tubular component 7 replicated by the plastic sleeve 25 can be determined based on the photographed picture. The high-definition camera device 31 avoids contact measurement of the plastic sleeve 25, avoids deformation of the plastic sleeve 25, and causes deviation in the measurement data.

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

[0058] The pressure component 4 is used to push the support core rod 21 into the tubular component 7, so that the plastic sleeve 25 extends into the tubular component 7, and 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, thereby preventing the plastic sleeve 25 and the plasticine inside from being located at one end of the support core rod 21. The influence of gravity causes the support core rod 21 to tilt, thereby affecting the accuracy of the plastic sleeve 25 replication and the accuracy of the length measurement.

[0059] like Figure 3-Figure 6 As shown, the pressure assembly 4 includes a threaded rod 41, with sliding brackets 43 movably mounted on both ends of the threaded rod 41, and a guide slide 45 fixedly mounted on the inner wall of the beam. The threaded rod 41 slides in the guide slide 45 through the slide 43;

[0060] The external threaded sleeve of the threaded rod 41 is provided with a transmission member 42, and the transmission member 42 is fixedly connected to the pressure plate 23 through the connecting frame 26;

[0061] The pressure components 4 are symmetrically arranged at both ends of the beam, and the thread directions of the two threaded rods 41 are opposite;

[0062] The opposite ends of the two threaded rods 41 are fixed with docking pieces 44 , which are composed of four annular rulers arranged at equal angles. The rulers of the docking pieces 44 at both ends are engaged 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 docking 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 are driven to move synchronously relative to each other along the threaded rods 41, ensuring that the two plastic sleeves 25 enter the tubular component 7 synchronously, and the interior of the tubular component 7 can be replicated through the plastic sleeve 25.

[0064] like Figure 8 As shown, the positioning assembly 5 includes a docking frame 51 fixed to the bottom of the beam, a transmission wheel 52 is provided at the bottom of the docking frame 51, a transmission belt 55 is provided for the external transmission of the transmission wheel 52, and positioning rods 54 are fixed at both ends of the transmission belt 55;

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

[0066] The tubular component 7 is pre-clamped by the clamp 6, and 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 rods 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 tubular component 7 is then clamped by the clamp 6, and the length inside the tubular component 7 can be replicated through the plastic sleeve 25.

[0067] The working principle and use process of the present invention:

[0068] The tubular component 7 is pre-clamped by the clamp 6, and 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 rods 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, and then the tubular component 7 is clamped by the clamp 6;

[0069] By pushing the two threaded rods 41 to move relative to each other, the threaded rods 41 slide along the guide slide 45 via the slide 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 docking members 44 engage with each other to form a circular tube, and the two second magnets 24 contact each other. By rotating the circular tube, the two threaded rods 41 rotate synchronously. Since the threads of the two threaded rods 41 are in opposite directions, the two transmission members 42 and the connecting frame 26 are driven to move synchronously relative to each other along the threaded rods 41.

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

[0071] The interior of the tubular component 7 is filled with the plastic sleeve 25 and the plasticine inside. At the same time, the plastic sleeve 25 is separated 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 device 31 and the plastic sleeve 25 are kept level. The high-definition camera device 31 is used to shoot the interior of the tubular component 7 replicated by the plastic sleeve 25. The length of the inside of the tubular component 7 replicated by the plastic sleeve 25 can be determined based on the photographed picture.
