Abstract

This invention discloses a wire exit positioning detection device, including a detection horizontal plate. Multiple strip-shaped grooves are horizontally formed on the detection horizontal plate, and a detection slider is slidably disposed within each strip-shaped groove. A U-shaped groove is formed on the detection slider, with cavities on both sides of the U-shaped groove. A rotating column is disposed within each of the two cavities, and a hollow liquid storage tube is coaxially connected to one end of each rotating column. Multiple elastic rubber tubes are circumferentially connected to the outer wall of the hollow liquid storage tube. The detection slider of this invention slides along the strip-shaped grooves to adjust its position. During wire measurement, the end of the wire approaches the detection slider. If the end of the wire does not reach the position of the detection slider, the wire exit is too short; if the end of the wire exceeds the position of the detection slider, the wire exit is too long. Furthermore, when the wire exit is too long, the pigment stored in the elastic rubber tubes is squeezed out and applied to the wire, thus marking and positioning the excessively long position of the wire.

Description

Technical Field

[0001] This invention relates to the field of power product outgoing line length detection technology, specifically to an outgoing line positioning detection device. Background Technology

[0002] When assembling certain products, such as motor control devices, the length of the three-phase wires is strictly required. If there is a deviation in the length of the three-phase wires, the three-phase wires of the motor may not be locked, leading to assembly failure. Therefore, it is necessary to strictly control the length of the wires. In existing technologies, manual inspection is generally carried out by using a tape measure or ruler to check each wire one by one. This inspection is inefficient and prone to errors.

[0003] The Chinese patent authorization announcement number is CN210603069U, entitled "A tool for measuring the length of wire harness outputs". It includes a base plate, a positioning pin, and a measuring rod. The base plate is provided with a measuring reference surface. The positioning pin is set axially on the measuring reference surface of the base plate, and the measuring rod is set radially on the base plate. The number of wire outputs of the measuring rod is matched with the number of wires output in the device being measured. During measurement, the positioning pin is inserted into the positioning hole of the device being measured, and then the length of each measuring rod from the end of the wire harness output in the device being measured is observed.

[0004] The shortcomings of the existing technical solutions are as follows: the solutions mainly rely on observing the distance between the measuring rod and the end of the product's lead wire to determine whether the lead wire length is qualified. However, the measuring rod in the existing solutions is fixed relative to the base plate and cannot be adjusted. It can only detect the lead wire length of one type of product and is not convenient for detecting other products. At the same time, it is also inconvenient to detect different lead wire lengths on the same product. Furthermore, for product lines with excessive lead wire lengths, it is impossible to mark and locate the excessive length. Therefore, when trimming the excessively long lines, it is necessary to remeasure the length with a ruler and then cut off the excess, which is not convenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide a wire exit positioning detection device to solve the technical problems in the prior art where the wire exit length detection device cannot be adjusted for different products and cannot mark and locate the position where the wire exit length is too long.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] A wire positioning detection device includes a detection horizontal plate, with support bases provided on both sides of the bottom of the detection horizontal plate, and a support assembly provided between the support bases and the detection horizontal plate.

[0008] An adjustable placement rack is provided at one end of the detection cross plate;

[0009] The detection plate has multiple horizontally formed strip grooves, and a detection slider is slidably disposed in each strip groove. A measuring ruler is disposed at the bottom of each strip groove.

[0010] The detection slider has a U-shaped groove, and cavities are provided on both sides of the U-shaped groove. A rotating column is provided in each of the two cavities. A hollow liquid storage tube is coaxially connected to one end of the rotating column. Multiple elastic rubber tubes are circumferentially connected to the outer wall of the hollow liquid storage tube, and the length of the elastic rubber tubes is greater than the radius of the rotating column. Multiple cracks are provided on one side of the elastic rubber tubes, and a one-way valve plate is provided at the end of the elastic rubber tubes near the hollow liquid storage tube.

[0011] As a further aspect of the present invention: the support assembly includes a support screw, which is connected to the support base, and the top end of the support screw penetrates the detection cross plate. Two fixing nuts are threaded onto the support screw, and the two fixing nuts are respectively located on both sides of the detection cross plate.

[0012] As a further embodiment of the present invention: the adjustable placement rack includes an adjusting screw and a support plate. The adjusting screw is rotatably connected to a corresponding support base. A threaded sleeve is threadedly connected to the adjusting screw. The support plate is connected to one side of the threaded sleeve. A limiting guide rod is also connected to the support base, and the limiting guide rod passes through one end of the support plate.

[0013] As a further aspect of the present invention: the adjusting screw is connected to a rotating handle near its upper end, and the rotating handle is located below the detection plate.

[0014] As a further aspect of the present invention: a fastening bolt is threaded onto the detection slider, and the fastening bolt penetrates the detection slider; an anti-slip layer is provided on the detection plate to cooperate with the fastening bolt.

[0015] As a further aspect of the present invention: a connecting groove is provided on the inner wall of the cavity, a slider is slidably disposed on the connecting groove, the rotating column is rotatably connected to the corresponding slider, and a limit spring is connected between the slider and the connecting groove.

[0016] As a further aspect of the present invention: one end of the one-way valve plate is rotatably connected to the inner wall of the elastic rubber tube via a spring-loaded hinge, and a limiting block that cooperates with the one-way valve plate is provided on the inner wall of the hollow liquid storage tube.

[0017] As a further aspect of the present invention: the hollow liquid storage tube is provided with a supply port, and a sealing plug is connected to the supply port; the detection slider is provided with a through-hole corresponding to the hollow liquid storage tube.

[0018] As a further aspect of the present invention: the elastic rubber tube is a transparent rubber tube, and one end of the elastic rubber tube is connected to the hollow liquid storage tube, while the other end is a closed end.

[0019] The beneficial effects of this invention are:

[0020] 1. The detection slider of this invention is positioned by a measuring ruler. When detecting the wire length of a product, the product is placed against one end of the detection plate, and the wire is straightened so that the end of the wire is close to the detection slider that has been adjusted to the correct position. If the end of the wire does not reach the position of the detection slider, the wire is too short. If the end of the wire exceeds the position of the detection slider, the wire length is too long. This facilitates quick detection and judgment. When the wire length is too long, the wire is inserted into the U-shaped groove on the detection slider. During the insertion process, the wire is squeezed against the elastic rubber tube, which makes it easier for the pigment stored in the elastic rubber tube to be squeezed out and applied to the wire, thereby marking and positioning the position where the wire is too long.

[0021] 2. When the thread is inserted into the U-shaped groove on the detection slider, the rotating columns on both sides can be separated by the slider body sliding along the connecting groove. At the same time, the rebound force of the limiting spring can keep the thread clamped on both sides, which is convenient for working with threads of different diameters. When the thread passes through the position between the rotating columns, the rotating columns rotate, so that the elastic rubber tube rotates synchronously and squeezes against the thread. At the same time, during the rotation, it is also convenient for the pigment in the hollow liquid storage tube to be replenished to the elastic rubber tube at different positions.

[0022] 3. The present invention has multiple detection sliders on the detection horizontal plate. Each detection slider can slide and adjust its position along the corresponding strip groove to facilitate the detection of the wire length of different products, reduce tooling costs, and detect multiple wires on the same product. It can also continuously detect the wire length of multiple products of the same type, and the detection effect is fast and convenient, improving production efficiency. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] like Figures 1-7 As shown, a wire positioning detection device includes a detection plate 1. Support bases 3 are provided on both sides of the bottom of the detection plate 1. A support assembly is provided between the support bases 3 and the detection plate 1. The support assembly includes a support screw 4. The support screw 4 is vertically fixedly connected to the support base 3, and the top end of the support screw 4 penetrates through the detection plate 1. Two fixing nuts 5 are threadedly connected to the support screw 4, and the two fixing nuts 5 are respectively located on both sides of the detection plate 1.

[0034] An adjustable mounting bracket is provided at one end of the testing horizontal plate 1. The adjustable mounting bracket includes an adjusting screw 6 and a support plate 8. The adjusting screw 6 is vertically rotatably connected to the corresponding support base 3 via a bearing. The top end of the adjusting screw 6 moves through the testing horizontal plate 1, meaning that the adjusting screw 6 can rotate relative to the testing horizontal plate 1. A threaded sleeve 7 is threadedly connected to the adjusting screw 6. The support plate 8 is horizontally fixedly connected to one side of the threaded sleeve 7. The support plate 8 is used to support the electrical product 9 to be tested. Here, the electrical product 9 is a product with an extension cord, such as a motor control device with three-phase wires. Since the length of the three-phase wire affects the assembly of the control device, the wire length requirement is strict and needs to be measured. The adjusting screw 6 is fixedly connected near the upper end with a... The handle 10 is located below the detection plate 1, which facilitates the support of the detection plate 1. The support base 3 is also vertically fixed with a limiting guide rod 13, which passes through one end of the tray 8. The tray 8 can slide relative to the limiting guide rod 13. When the power product 9 is placed on the tray 8, the adjusting screw 6 is rotated by the handle 10. During the rotation of the adjusting screw 6, the tray 8 is limited by the limiting guide rod 13 and cannot rotate with the adjusting screw 6. Thus, the threaded sleeve 7 connected to the tray 8 moves up and down along the adjusting screw 6, thereby realizing the up and down position adjustment of the tray 8, so as to realize the height position adjustment of the power product 9, and finally making the outlet position of the power product 9 flush with the upper surface of the detection plate 1.

[0035] Multiple strip grooves 2 are horizontally opened on the detection plate 1. A detection slider 11 is slidably installed in each strip groove 2. A measuring ruler 14 is installed at the bottom of the strip groove 2. The end of the measuring ruler 14 closest to the support plate 8 is the minimum value end. When detecting the output length of the power product 9, the detection slider 11 is first slid along the strip groove 2 until it slides to the corresponding value position of the measuring ruler 14. Then, the wire on the power product 9 is straightened so that its end is close to the detection slider 11. If the end of the wire does not reach the position of the detection slider 11 or exceeds the position of the detection slider 11, it means that the output length is unqualified.

[0036] The detection slider 11 is threaded with a fastening bolt 16, which passes through the detection slider 11. The detection horizontal plate 1 is provided with an anti-slip layer 15 that cooperates with the fastening bolt 16. When the detection slider 11 slides to the corresponding position and stops, the fastening bolt 16 is rotated so that the bottom end of the fastening bolt 16 abuts against the corresponding position of the anti-slip layer 15, thus keeping the detection slider 11 in a stable position relative to the detection horizontal plate 1.

[0037] The detection slider 11 has a U-shaped groove 17, and cavities 18 are provided on both sides of the U-shaped groove 17. A rotating column 12 is provided in each of the two cavities 18. Anti-slip grooves are distributed circumferentially on the outer wall of the rotating column 12. Connecting grooves 21 are horizontally provided on the inner walls of both sides of the cavity 18. A slider body 19 is slidably mounted in each of the two connecting grooves 21. The rotating column 12 is rotatably connected to the corresponding slider body 19. A limit spring 20 connects the slider body 19 and the connecting groove 21. The two rotating columns 12 are initially close to each other. When the end of the power product 9's wire is inserted into the U-shaped groove 17, the wire squeezes the two sides... The rotating column 12 slides along the connecting groove 21 into the cavity 18, supported by the slider 19. During this process, the limiting spring 20 is compressed, generating a rebound force, which facilitates the clamping of the rotating column 12 on both sides of the wire body. This allows for the detection of wire bodies of various diameters. A hollow liquid storage tube 22 is coaxially connected to one end of the rotating column 12. The hollow liquid storage tube 22 is filled with colored pigment. Multiple elastic rubber tubes 24 are circumferentially connected to the outer wall of the hollow liquid storage tube 22. The length of the elastic rubber tubes 24 is greater than the radius of the rotating column 12. The elastic rubber tubes 24 are transparent rubber tubes, and one end of the elastic rubber tube 24 is connected to the hollow liquid storage tube 22. One end is closed, allowing some pigment to enter the elastic rubber tube 24 when colored pigment is injected into the hollow liquid storage tube 22. Because it is a transparent tube, the pigment injection process is easy to observe. Multiple slits 26 are provided on one side of the elastic rubber tube 24. When the elastic rubber tube 24 is not compressed, the slits 26 are closed, preventing liquid from passing through if it is inside. When the elastic rubber tube 24 is compressed, the slits 26 open, allowing the pigment to flow out. A one-way valve 25 is provided at the end of the elastic rubber tube 24 near the hollow liquid storage tube 22. One end of the one-way valve plate 25 is rotatably connected to the inner wall of the elastic rubber tube 24 via a spring hinge. A limiting block 27 that cooperates with the one-way valve plate 25 is provided on the inner wall of the hollow liquid storage tube 22. When the one-way valve plate 25 is engaged with the limiting block 27, the end of the elastic rubber tube 24 is closed. The limiting block 27 prevents the one-way valve plate 25 from rotating into the hollow liquid storage tube 22, but only into the elastic rubber tube 24. This ensures that the pigment injected into the hollow liquid storage tube 22 can only flow into the elastic rubber tube 24 and cannot flow back from the elastic rubber tube 24 into the hollow liquid storage tube 22.

[0038] When the end of the power product 9 is pressed into the U-shaped groove 17 on the corresponding detection slider 11, the wire squeezes and opens the rotating columns 12 on both sides. As the wire passes through the gap between the rotating columns 12, the rotating columns 12 rotate due to friction, thereby driving the circumferentially distributed elastic rubber tubes 24 to rotate. Since the length of the elastic rubber tubes 24 is greater than the radius of the rotating columns 12, the end of the elastic rubber tubes 24 extends beyond the outer wall of the rotating columns 12, thus facilitating compression between the elastic rubber tubes and the outer wall of the wire during the pressing process. During the compression process, cracks are formed in the elastic rubber tubes 24. 26 is opened to facilitate the outflow of colored pigment inside, so that it can be applied to the thread. This allows for marking and positioning of the excessively long part of the thread, making it convenient to trim the excessively long part. During the compression of the elastic rubber tube 24, the one-way valve 25 prevents the pigment from flowing into the hollow liquid storage tube 22, so that the pigment can be squeezed out from the crack 26. Whenever the elastic rubber tube 24 rotates downward with the rotating column 12, the pigment in the hollow liquid storage tube 22 can push open the one-way valve 25 and replenish the elastic rubber tube 24.

[0039] The hollow liquid storage tube 22 is provided with a supply port 23, and a sealing plug is connected to the supply port 23. The detection slider 11 is provided with a through port corresponding to the hollow liquid storage tube 22. When it is necessary to supply pigment into the hollow liquid storage tube 22, the supply port 23 is opened from the position of the through port, and then pigment is supplied into the hollow liquid storage tube 22 from the supply port 23.

[0040] The working principle of this invention is as follows: The power product 9 is placed on the tray 8. Then, the adjusting screw 6 is rotated via the handle 10. During the rotation of the adjusting screw 6, the tray 8 is limited by the guide rod 13 and cannot rotate with the adjusting screw 6. Thus, the threaded sleeve 7 connected to the tray 8 moves up and down along the adjusting screw 6, adjusting the position of the tray 8 and thereby adjusting the height of the power product 9. Finally, the outlet position of the power product 9 is aligned with the upper surface of the detection plate 1. Then, according to the number of outlets of the power product 9, a corresponding number of detection sliders 11 are selected and adjusted, allowing each detection slider 11 to slide along the strip groove 2 until it reaches the corresponding value position on the measuring ruler 14. The position is then fixed by the fastening bolts 16. Once the position of the detection sliders 11 is determined, the outlet length of multiple identical power products 9 can be continuously tested for compliance. This device can also be adjusted to test different products, saving costs.

[0041] When performing wire length detection, the wires at different positions are straightened sequentially so that the ends of the wires are close to the corresponding detection sliders 11. If the ends of the wires cannot reach the positions of the detection sliders 11, it means that the wire length is too short. If the ends of the wires can reach the positions of the detection sliders 11, the ends of the wires are first pressed into the U-shaped grooves 17 on the corresponding detection sliders 11. During the pressing process, the wires squeeze the rotating posts 12 on both sides. The rotating posts 12 slide into the cavity 18 along the connecting grooves 21 by the slider body 19. During this process, the limiting spring 20 is compressed to generate a rebound force, which makes it easy for the rotating posts 12 to clamp the sides of the wires. In this way, wires of various diameters can be detected.

[0042] When the line passes through the gap between the rotating posts 12, the rotating posts 12 rotate due to friction, thereby driving the circumferentially distributed elastic rubber tubes 24 to rotate. Since the length of the elastic rubber tubes 24 is greater than the radius of the rotating posts 12, the end of the elastic rubber tubes 24 extends beyond the outer wall of the rotating posts 12, which facilitates the compression between the elastic rubber tubes 24 and the outer wall of the line during the pressing process. During the compression process, the elastic rubber tubes 24 cause the cracks 26 to open, which facilitates the flow of colored pigments inside, so that they can be applied to the line. In this way, the excessive length of the line can be marked and located, making it convenient to trim the excessively long part of the line.

[0043] Furthermore, during the compression of the elastic rubber tube 24, the one-way valve plate 25 blocks the pigment from flowing into the hollow liquid storage tube 22, making it easier for the pigment to be squeezed out from the crack 26. Also, whenever the elastic rubber tube 24 rotates downwards with the rotating column 12, the pigment in the hollow liquid storage tube 22 can push open the one-way valve plate 25 and be replenished into the elastic rubber tube 24.

[0044] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
