Description

Technical Field

[0001] The present invention relates to the field of cable measurement, in particular to an external dimension measuring device for composite cable production. Background Art

[0002] In the production process of composite cables, accurate measurement of external dimensions and assessment of their appearance quality are crucial. Cable dimensions, such as diameter and ovality, are directly related to the cable's electrical and mechanical properties, as well as its compatibility with other equipment. Defects such as variations in thickness and wear on the cable surface not only affect the cable's appearance but also pose a potential threat to its service life and safety.

[0003] At present, the measurement method commonly used in the industry is sampling measurement, that is, a certain number of samples are extracted from the entire batch of cables produced, and these samples are measured for size and appearance inspection. However, this sampling measurement method has obvious limitations. On the one hand, since only part of the samples are measured, it is impossible to fully reflect the actual size of the entire cable. Various unstable factors may exist in the cable production process, resulting in differences in the sizes of different parts. Sampling measurement is likely to miss cables whose sizes exceed the standard range, thus making it impossible to guarantee the accuracy of the measurement. On the other hand, sampling measurement makes it difficult to intuitively judge whether there are problems such as thickness changes or surface wear on the entire cable. It is difficult to discover these problems in time through sampling measurement alone. These potential problems may gradually appear after the cable is put into use, causing various faults and safety hazards. Therefore, how to solve the above problems needs to be considered.

[0015] The present invention also discloses a method for using a device for measuring the dimensions of composite cables, which comprises the following steps:

[0016] Step 1: Use traceless glue to stick the paper on the rotating column to form a paper tube, making sure that the paper tube covers the surface of the rotating column. This is ready for recording the test results and conveniently presenting the cable test information intuitively.

[0017] Step 2: After installing the cable, start the dual-axis motor. The left output shaft drives the first rotating tube to rotate through the first transmission belt. The bristles clean the dust on the surface of the cable, and the axial flow fan blades rotate to generate airflow, blowing the dust away from the detection part.

[0018] Step 3: At the initial stage of cable movement, the detection ring moves right to the equilibrium position.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The cable is wrapped with an annular airbag to generate contact pressure, ensuring stable contact between the cable and the measuring mechanism during testing. The force balance between the cable and the detection ring during movement and the subsequent pressure change feedback are used to accurately capture changes in cable thickness, effectively improve measurement accuracy, and ensure reliable test results. The entire cable was tested, and compared with existing technologies, the overall accuracy has been improved, avoiding the situation where local sampling leads to inaccurate test results.

[0022] 2. The combined design of brush cleaning and axial fan blades blowing away dust in the cleaning mechanism can promptly remove dust on the cable surface before testing, avoiding dust affecting measurement accuracy, ensuring that the measurement process is carried out in a clean environment, and improving the quality of testing.

[0023] 3. A rotating column is used in conjunction with a paper tube. Different marks are left on the paper tube by the first and second indicator pens. The changes in cable thickness and surface wear are presented in the form of intuitive spiral lines. Users can quickly determine whether the cable is qualified by observing the changes in the lines. This is convenient and efficient.

[0024] 4. By taking advantage of the different effects of cable diameter change and surface wear on the annular airbag pressure, the double lines on the paper tube show different characteristics, which can effectively distinguish between the two situations of cable diameter change and surface wear, providing a more accurate basis for judging cable problems.

[0025] 5. Using paper tubes with spiral lines to record test results can make full use of paper space and avoid paper waste. While ensuring the completeness of test results, it reduces test costs and meets the needs of environmental protection and economic practicality.

[0026] In summary, the device can conduct comprehensive inspection of cables during use, avoiding inaccurate local inspections. In addition, the inspection is highly intuitive, facilitating practical judgments. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end of the second piston plate 39 is elastically connected to the inner bottom of the adjusting cylinder 21 through a second spring 40. The adjusting cylinder 21 is made of transparent material. When the air pressure inside it changes, the second piston plate 39 will move up or down to a certain extent. It plays a certain indicating role and achieves the measurement effect. In the preparation stage of the test, one end of the cable is connected to the external unwinding device, and the other end is connected to the external winding device, and the lower end face of the cable contacts the two guide rollers 3. In addition, it passes through the first rotating tube 20, the second rotating tube 26 and the detection ring 28. It should be noted that when the detection is performed through the operation, the vertical bar 41 can be lifted first to move the second piston plate 39 upward so that part of the gas in the annular airbag 29 is extracted. At this time, it is convenient for the cable to pass through. After the passing is completed, the vertical bar 41 is released, and the annular airbag 29 will wrap the cable and have a certain contact pressure to ensure the accuracy of subsequent detection.

[0043] As an embodiment of the present invention, a connecting ring is fixedly connected to the right side of the first rotating tube 20, and a second rotating tube 26 is fixedly connected to the right side of the connecting ring. A plurality of axial flow blades 27 are arranged on the outside of the second rotating tube 26, and a plurality of connecting ports 25 are opened on the plurality of axial flow blades 27.

When the axial flow blades 27 are started, the airflow generated can blow the swept dust away from the detection part to avoid affecting the actual detection.

[0044] As an embodiment of the present invention, it also includes an indicating mechanism, which cooperates with the measuring mechanism to display the measurement results. The indicating mechanism includes a U-shaped plate 48 arranged on the front side of the vertical plate 5. The inner top and inner bottom of the U-shaped plate 48 are both rotatably connected to the rotating tube 10 through bearings. The opposite ends of the two rotating tubes 10 are commonly fixedly connected to the rotating column 38. The rotating tube 10 and the rotating column 38 are both vertically penetrated with a first strip-shaped opening, and the two horizontal parts of the U-shaped plate 48 are penetrated with a second strip-shaped opening. The horizontal plate 6 is vertically A rotating shaft 52 is provided through it, and the rotating shaft 52 is rotatably connected to the horizontal plate 6. The lower end of the rotating shaft 52 is fixedly connected to the rotating bar 51, and the lower end of the rotating bar 51 passes through the corresponding two second strip-shaped openings and the first strip-shaped opening. A sliding groove 49 is provided on the front side of the vertical plate 5, and a reciprocating screw rod 16 is rotatably connected between the upper and lower inner walls of the sliding groove 49. A sliding bar 50 is threadedly connected to the reciprocating screw rod 16, and the sliding bar 50 is slidably connected to the inner wall of the sliding groove 49. The front side of the sliding bar 50 passes through the notch of the sliding groove 49 and is fixedly connected to the rear side of the U-shaped plate 48.

[0045] As an embodiment of the present invention, the upper end of the reciprocating screw 16 passes through the cross plate 6, and the reciprocating screw 16 and the upper end of the rotating shaft 52 are both installed with a second pulley 17. The two second pulleys 17 are connected by a second transmission belt 18. The right side of the mounting plate 11 is fixedly connected with a transmission 13. The transmission 13 is a reducer. By using the transmission 13, the subsequent low-speed rotation of the reciprocating screw 16 and the rotating shaft 52 can be achieved. The input end of the transmission 13 passes through the mounting plate 11 and is fixedly connected to the right end output shaft of the dual-axis motor 12. The output shaft of the transmission 13 is fixedly connected to the first bevel gear 14, and the upper end of the reciprocating screw 16 is fixedly connected to the second bevel gear 15. The first bevel gear 14 and the second bevel gear 1 5 is engaged, a rectangular bar 30 is fixedly connected to the inner top of the measuring cylinder 7, a rectangular groove 31 is formed at the lower end of the rectangular bar 30, a guide rod 32 is fixedly connected between the left and right inner walls of the rectangular groove 31, a moving block 33 is penetrated by the guide rod 32, the moving block 33 is slidably connected to the inner wall of the rectangular groove 31, the left side of the moving block 33 is elastically connected to the left inner wall of the rectangular groove 31 by a first spring 34, a connecting rod 37 is fixedly connected to the right side of the moving block 33, a first piston cylinder 35 is fixedly connected to the right side of the rectangular bar 30, a first piston plate 36 that can slide left and right is provided in the first piston cylinder 35, and the right end of the connecting rod 37 extends into the first piston cylinder 35 and is fixedly connected to the left side of the first piston plate 36.

[0046] As an embodiment of the present invention, the upper end of the second piston plate 39 is fixedly connected to a vertical bar 41, the upper end of the vertical bar 41 passes through the inner top of the adjustment cylinder 21, the rear side of the vertical bar 41 is fixedly connected to a mounting column 42, the rear end of the mounting column 42 is installed with a first indicator pen 43, the rear side of the vertical bar 41 is fixedly connected to the second piston cylinder 45, the second piston cylinder 45 is provided with a third piston plate 47 that can slide back and forth, the rear side of the third piston plate 47 is fixedly connected to a moving bar 44, the rear end of the moving bar 44 extends to the outside and is fixed. A second indicator pen 46 is fixedly connected. The front space of the second piston cylinder 45 is connected to the right space of the first piston cylinder 35 through the first connecting tube 22. The first indicator pen 43 and the second indicator pen 46 are different colors. In actual use, a paper tube is first formed on the rotating column 38 using paper and traceless glue. The paper tube just covers the surface of the rotating column 38. In the initial state, the first indicator pen 43 and the second indicator pen 46 are both located at the bottom part of the rotating column 38. The first indicator pen 43 contacts the paper tube, while the second indicator pen 46 does not.

[0047] In the present invention, a paper tube is first formed on the rotating column 38 using paper and traceless glue, and the paper tube just covers the surface of the rotating column 38. One end of the cable is connected to the external unwinding device, and the other end is connected to the external winding device, so that the lower end surface of the cable contacts the two guide rollers 3, and passes through the first rotating tube 20, the second rotating tube 26 and the detection ring 28 in the measuring tube 7, and the vertical bar 41 is lifted, which drives the second piston plate 39 to move upward in the adjusting tube 21, compressing the second spring 40. At the same time, the gas in the adjusting tube 21 is compressed, and part of the gas in the annular airbag 29 is extracted to facilitate the passage of the cable. After the cable is passed through, the vertical bar 41 is loosened, and under the elastic force of the second spring 40, the second piston plate 39 moves downward, the air pressure in the adjusting tube 21 changes, and the gas enters the annular airbag 29, so that the annular airbag 29 wraps the cable and generates a certain contact pressure to ensure the accuracy of subsequent detection;

[0048] Then, the test is carried out, and the external reeling and winding device is in operation. In the initial stage of cable movement, its movement will use friction to drive the detection ring 28 to move right. Due to the uniform speed, the detection ring 28 will eventually maintain the equilibrium position when the force is balanced. At this time, the first piston plate 36 is in a fixed position. The third piston plate 47 will move backward by gas transmission, causing the movable bar 44 to move backward and the second indicator pen 46 to move backward, reaching the equilibrium position (not contacting the paper tube).

[0049] Then the dual-axis motor 12 is started, and its left output shaft and the first pulley 8 on the first rotating tube 20 are driven by the first transmission belt 9 to drive the first rotating tube 20 to rotate. When the first rotating tube 20 rotates, the multiple bristles 24 on its inside clean the dust on the surface of the cable, sweep the dust down and lift it up, and the first rotating tube 20 drives the connecting ring and the second rotating tube 26 to rotate, thereby causing the multiple axial flow fan blades 27 on the outside of the second rotating tube 26 to rotate, generating an airflow from right to left, blowing the raised dust away from the detection part to prevent dust from affecting the measurement accuracy. The output shaft at the right end of the dual-axis motor 12 drives the input end of the transmission 13 to rotate. The transmission 13 acts as a reducer to rotate the output shaft at a low speed, thereby driving the first bevel gear 14 to rotate. The first bevel gear 14 is meshed with the second bevel gear 15, driving the reciprocating screw 16 to rotate, and the slide bar 50 on the reciprocating screw 16 slides downward in the slide groove 49, driving the U-shaped plate 48 to move downward, so that the rotating column 38 moves downward at a uniform speed.

[0050] The reciprocating screw 16 and the second pulley 17 at the upper end of the rotating shaft 52 are driven by the second transmission belt 18, driving the rotating shaft 52 to rotate, thereby causing the rotating bar 51 to drive the rotating column 38 to rotate at a constant speed. When the thickness of the cable changes, the cable generates different pressures on the annular airbag 29, causing the annular airbag 29 to contract or expand. Then, with the cooperation of the second connecting tube 23, the gas pressure at the bottom of the regulating cylinder 21 changes, causing the second piston plate 39 to move up or down, causing the vertical bar 41 to move up or down, driving the first indicator pen 4 thereon. 3. If the cable diameter does not change, as the rotating column 38 moves downward and rotates at a uniform speed, a spiral line with equal spacing and no fluctuation will be drawn on the paper tube. If the cable diameter suddenly increases, the spiral line will fluctuate upward at some point. Similarly, if the cable diameter suddenly decreases, the spiral line will fluctuate downward at some point. In order to ensure the actual detection accuracy and avoid the cable being too thin or too thick as a whole, the diameter of the cable end part can be tested before the test to eliminate the detection error caused by this problem.

[0051] It should be noted that when the cable diameter suddenly increases, the increased contact friction will cause the cable to move to the right. The movable block 33 will then move rightward again by a certain distance, causing the first piston plate 36 to move rightward again and the third piston plate 47 to move backward again. This allows the second indicator pen 46 to contact the paper tube via the movable bar 44. In other words, if the cable diameter suddenly increases, a double line will appear on the paper tube at that location, and the line generated by the first indicator pen 43 will have an upward fluctuation. Furthermore, if the cable surface is worn, a sudden increase in cable diameter can also occur. The difference between the two is that the cable does not compress the annular airbag 29 at this time, so the line generated by the first indicator pen 43 in the double line does not have an upward fluctuation. Ultimately, the user only needs to observe the changes in the lines on the paper tube to determine the overall measurement results of the actual cable. Any of the following problems, such as thickening, thinning, or wear, indicates that the cable is unqualified, facilitating actual judgment. The use of a paper tube in conjunction with the spiral lines maximizes paper utilization and avoids paper waste.

[0052] The present invention also discloses a method for using a device for measuring the dimensions of composite cables, which comprises the following steps:

[0053] Step 1: Use traceless glue to stick the paper on the rotating column 38 to form a paper tube, making sure that the paper tube covers the surface of the rotating column 38, so as to prepare for the subsequent recording of the test results and facilitate the intuitive presentation of the cable test information;

[0054] Step 2: After the cable is installed, the dual-axis motor 12 is started. The left output shaft drives the first rotating tube 20 to rotate through the first transmission belt 9. The bristles 24 clean the dust on the surface of the cable. The axial flow blades 27 rotate to generate airflow to blow the dust away from the detection part.

[0055] Step 3: At the initial stage of cable movement, the detection ring 28 is driven to the right to the equilibrium position. The right end output shaft of the dual-axis motor 12 drives the reciprocating screw 16 to rotate through the transmission 13, the first bevel gear 14, and the second bevel gear 15. The slide bar 50 slides down to move the U-shaped plate 48 downward. The rotating column 38 moves downward and rotates at a uniform speed to achieve the detection operation in coordination with the movement of the cable.

[0056] Step 4: After the test is completed, the user observes the changes in the spiral lines on the paper tube. If there are fluctuations corresponding to thickening, thinning, or wear, the cable can be judged as unqualified, and the test results can be obtained quickly and conveniently.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
