Description

Technical Field

[0001] The present invention relates to the field of cable measurement, and particularly to a device for measuring the external dimensions of composite cables during production. Background Art

[0002] During the production process of composite cables, the accurate measurement of external dimensions and the judgment of their appearance quality are crucial steps. Parameters such as the diameter and ovality of the cable's external dimensions directly affect the electrical performance, mechanical performance of the cable, as well as its compatibility with other devices. Whether there are defects such as thickness variations and abrasions on the cable surface not only affects the aesthetics of the cable but may also pose potential threats to its service life and safety. Currently, the commonly used measurement method in the industry is sampling measurement, that is, a certain number of samples are extracted from the entire batch of cables produced, and the dimensions of these samples are measured and their appearance is inspected. However, this sampling measurement method has obvious limitations. On the one hand, since only part of the samples are measured, it is impossible to comprehensively reflect the actual dimension situation of the entire cable. There may be various unstable factors during the cable production process, resulting in dimensional differences in different parts. Sampling measurement is very likely to miss those cables with dimensions exceeding the standard range, thus unable to guarantee the accuracy of the measurement. On the other hand, it is difficult to intuitively judge whether there are thickness variations or surface abrasions on the entire cable through sampling measurement, and it is very difficult to detect them in a timely manner only through sampling measurement. These potential problems may gradually appear after the cable is put into use, leading to various failures and safety hazards. Therefore, how to solve the above problems needs to be considered.

[0012] The present invention also discloses a usage method of an outer dimension measuring device for composite cable production. Using the above measuring device, it includes the following steps: Step 1: On the rotating column, use a non-trace adhesive to attach paper to form a paper tube, ensuring that the paper tube covers the surface of the rotating column, preparing for subsequent recording of detection results and facilitating the intuitive presentation of cable detection information. Step 2: After the installation operation of the cable, start the double-shaft motor. Its left output shaft drives the first rotating tube to rotate through the first transmission belt.

Compared with the prior art, the overall accuracy is improved, and the situation of inaccurate detection results caused by local sampling is avoided.

[0014] 2. The combined design of the brush bristles for cleaning and the axial flow fan blades for blowing away dust in the cleaning mechanism can timely remove the dust on the surface of the cable before detection, avoiding the influence of dust on the measurement accuracy, ensuring that the measurement process is carried out in a clean environment, and improving the detection quality.

[0015] 3. A rotating column is used in cooperation with a paper tube. Different marks are left on the paper tube by the first indicating pen and the second indicating pen, presenting the cable thickness change and surface wear condition in the form of intuitive spiral lines. Users can quickly judge whether the cable is qualified by observing the line changes, which is convenient and efficient.

[0016] 4. By taking advantage of the different effects of cable diameter change and surface wear on the pressure of the annular airbag, different characteristics are presented in the double lines on the paper tube, which can effectively distinguish between the two situations of cable diameter change and surface wear, providing a more accurate basis for judging cable problems.

[0017] 5. Using the paper tube in cooperation with the spiral lines to record the detection results can make full use of the paper space, avoid waste of paper, and while ensuring the complete recording of the detection results, reduce the detection cost, meeting the requirements of environmental protection and economic practicality.

In addition, the lower end surface of the cable contacts two guide rollers 3, and also penetrates through the first rotating pipe 20, the second rotating pipe 26, and the detection ring 28. It should be noted that when performing the passing operation during detection, the vertical bar 41 can be lifted first to make the second piston plate 39 move up, so that part of the gas in the annular airbag 29 is pumped away.

A plurality of axial flow blades 27 are arranged on the outer side of the second rotating tube 26, and a plurality of connecting ports 25 are opened on the plurality of axial flow blades 27.

[0025] 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 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 vertically penetrated by a first strip opening, and the two horizontal parts of the U-shaped plate 48 are penetrated by a second strip 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 a 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 opened on the front side of the vertical plate 5, and a reciprocating screw 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 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.

[0026] As an implementation manner of the present invention, the upper end of the reciprocating lead screw 16 penetrates through the transverse plate 6.

The two second belt pulleys 17 are connected by a second transmission belt 18. A transmission 13 is fixedly connected to the right side of the mounting plate 11. The transmission 13 is a speed reducer. By using the transmission 13, the subsequent low-speed rotation of the reciprocating lead screw 16 and the rotating shaft 52 can be realized.

The output shaft of the transmission 13 is fixedly connected to a first bevel gear 14. The upper end of the reciprocating lead screw 16 is fixedly connected to a second bevel gear 15. The first bevel gear 14 meshes with the second bevel gear 15. A rectangular bar 30 is fixedly connected to the inner top of the measuring cylinder 7. A rectangular groove 31 is opened at the lower end of the rectangular bar 30. A guide rod 32 is fixedly connected between the left and right inner side walls of the rectangular groove 31. A moving block 33 is arranged through 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 side wall of the rectangular groove 31 through 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 arranged in the first piston cylinder 35. 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.

[0027] As an implementation manner of the present invention, a vertical bar 41 is fixedly connected to the upper end of the second piston plate 39. The upper end of the vertical bar 41 penetrates through the inner top of the adjusting cylinder 21. An installation column 42 is fixedly connected to the rear side of the vertical bar 41. A first indicating pen 43 is installed at the rear end of the installation column 42. A second piston cylinder 45 is fixedly connected to the rear side of the vertical bar 41. A third piston plate 47 that can slide back and forth is arranged in the second piston cylinder 45. A moving bar 44 is fixedly connected to the rear side of the third piston plate 47. The rear end of the moving bar 44 extends to the outside and is fixedly connected to a second indicating pen 46. The front space of the second piston cylinder 45 is communicated with the right space of the first piston cylinder 35 through a first connecting pipe 22. The colors of the first indicating pen 43 and the second indicating pen 46 are different. In actual use, first, a paper tube is formed on the rotating column 38 by using paper and a non-trace adhesive. The paper tube just covers the surface of the rotating column 38. In the initial state, both the first indicating pen 43 and the second indicating pen 46 are located at the bottom part of the rotating column 38. The first indicating pen 43 contacts the paper tube, and the second indicating pen 46 does not contact the paper tube.

[0028] In the present invention, a paper tube is first formed on the rotating column 38 by using paper and a traceless adhesive. The paper tube just covers the surface of the rotating column 38. One end of the cable is connected to an external unwinding device, and the other end is connected to an external winding device. The lower end surface of the cable contacts the two guide rollers 3 and passes through the detection ring 28 in the first rotating tube 20, the second rotating tube 26, and the measuring cylinder 7. Lift the vertical strip 41 to drive the second piston plate 39 to move upward in the adjusting cylinder 21, compress the second spring 40. At the same time, the gas in the adjusting cylinder 21 is compressed, and part of the gas in the annular airbag 29 is pumped away to facilitate the cable to pass through. After the cable passes through, release the vertical strip 41. Under the elastic force of the second spring 40, the second piston plate 39 moves downward, the air pressure in the adjusting cylinder 21 changes, and the gas enters the annular airbag 29 to wrap the cable and generate a certain contact pressure to ensure the accuracy of subsequent detection. Subsequently, the detection is carried out. The external winding and unwinding device operates. In the initial stage of the cable movement, its movement will drive the detection ring 28 to move to the right by friction. Due to the uniform speed state, finally, in the force balance state, the detection ring 28 will maintain the equilibrium position and not move. At this time, the first piston plate 36 is in a fixed position. Using the transmission of gas, the third piston plate 47 will move backward, driving the moving strip 44 to move backward and driving the second indicating pen 46 to move backward to be in the equilibrium position (not in contact with the paper tube). Subsequently, the dual-axis motor 12 is started. The left output shaft of the dual-axis motor 12 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, multiple bristles 24 on its inner side clean the dust on the surface of the cable, sweeping and raising the dust. The first rotating tube 20 drives the connecting ring and the second rotating tube 26 to rotate, and further drives the multiple axial flow fan blades 27 on the outer side of the second rotating tube 26 to rotate, generating an air flow from right to left to blow the raised dust away from the detection part to avoid the influence of dust on the measurement accuracy. The right output shaft of the dual-axis motor 12 drives the input end of the transmission 13 to rotate. The transmission 13 acts as a reducer to make the output shaft rotate at a low speed, and then drives the first bevel gear 14 to rotate. The first bevel gear 14 meshes with the second bevel gear 15 to drive the reciprocating lead screw 16 to rotate. The slide 50 on the reciprocating lead screw 16 slides downward in the chute 49, driving the U-shaped plate 48 to move downward, so that the rotating column 38 moves downward at a uniform speed.

[0029] The reciprocating lead screw 16 is driven by a second drive belt 18 to the second pulley 17 at the upper end of the rotating shaft 52, driving the rotating shaft 52 to rotate. Further, the rotating bar 51 drives the rotating column 38 to rotate at a constant speed. When there are thickness variations in the cable, the cable exerts different pressures on the annular airbag 29, causing the annular airbag 29 to contract or expand. Further, with the cooperation of the second connecting pipe 23, the gas pressure at the bottom inside the adjusting cylinder 21 changes, causing the second piston plate 39 to move upward or downward, causing the vertical bar 41 to move upward or downward, driving the first indicating pen 43 thereon to move upward or downward. If the diameter of the cable does not change, as the rotating column 38 moves downward and rotates at a constant speed, a non-fluctuating spiral line with equal spacing will be drawn on the paper tube. If the cable diameter suddenly becomes larger, the spiral line will have an upward fluctuation at a certain point. Similarly, if the cable diameter suddenly becomes smaller, the spiral line will have a downward fluctuation at a certain point. To ensure the accuracy of actual detection and avoid the cable being uniformly thinner or thicker, the diameter of the end part of the cable can be detected before this detection to eliminate the detection error caused by this problem.

[0030] It should be noted that after the cable diameter suddenly becomes larger, due to the increase in contact friction, during the rightward movement of the cable, the moving block 33 will move a further distance to the right on the basis of the rightward movement, causing the first piston plate 36 to move rightward again and the third piston plate 47 to move backward again. Through the moving bar 44, the second indicating pen 46 contacts the paper tube. That is, actually, if the cable diameter suddenly becomes larger, there will be a double line at this position on the paper tube, and the line generated by the first indicating pen 43 has an upward fluctuation. Additionally, if there is wear on the cable surface, it will also cause the cable diameter to suddenly become larger. The difference between the two is that at this time, the cable will not compress the annular airbag 29. Therefore, there is no upward fluctuation in the line generated by the first indicating pen 43 in the double line generated at this time. Finally, the user only needs to observe the line changes on the paper tube to judge the overall measurement result of the actual cable. If any one of the problems of thickening, thinning, or wear occurs, it means that the cable is unqualified, facilitating the actual judgment. By using the paper tube in cooperation with the spiral line, the utilization rate of the paper can be maximized, avoiding waste of the paper.

[0031] The present invention also discloses a method for using an external dimension measuring device for composite cable production, using the above-mentioned measuring device, including the following steps: Step 1: On the rotating column 38, use a non-trace adhesive to attach a paper to form a paper tube, ensuring that the paper tube covers the surface of the rotating column 38, preparing for subsequent recording of the detection results and facilitating the intuitive presentation of cable detection information; Step 2: After the cable installation operation, start the dual-axis motor 12. Its left output shaft drives the first rotating tube 20 to rotate through the first transmission belt 9. The brush hairs 24 clean the dust on the cable surface, and the axial flow fan blades 27 rotate to generate an air flow to blow the dust away from the detection part; Step 3: At the initial stage of the cable movement, the detection ring 28 is driven to move rightward to the balanced position. The right output shaft of the dual-axis motor 12 drives the reciprocating lead screw 16 to rotate through the transmission 13, the first bevel gear 14, and the second bevel gear 15. The slider 50 slides downward to make the U-shaped plate 48 move downward. The rotating column 38 moves downward at a uniform speed and rotates, cooperating with the cable operation to achieve the detection operation; Step 4: After the detection is completed, the user observes the change of the spiral lines on the paper tube. If there are corresponding line fluctuations such as thickening, thinning, or wear, it can be judged that the cable is unqualified, and the detection result can be obtained conveniently and quickly.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
