Description

Technical Field

[0001] The invention relates to the technical field of cable detection, in particular to a wear-resistant detection device for cable production. Background Art

[0002] The wear test device for cable production is a device specially used to evaluate the wear resistance of cables. It usually includes a base, a vertical plate, a mounting plate, a cable limit structure, a mounting frame (such as a rectangular sleeve, a first arc-shaped strip and an inner wall with a friction layer), a cable cooling mechanism and a chip removal mechanism. The device simulates the wear of the cable in actual use, uses the friction layer to perform continuous wear tests on the cable, and is equipped with a cooling mechanism to reduce the impact of temperature on the test results. The chip removal mechanism collects the debris generated by wear, which is convenient for observing and judging the wear resistance of the cable. This detection device is of great significance to ensure the quality and durability of cable products.

[0003] For example, the Chinese authorized patent "A Wear Resistance Detection Device for Cable Production" with announcement number CN214251892U includes a detection box, a support plate and a sliding mechanism. Both sides of the detection box are fixedly connected with supports; the sliding mechanism includes a slide groove, a slider, a slide plate and a tooth plate, and a slide groove is provided on the top of the detection box. The present invention provides a slide groove so that the support plate on the slider has the function of directional movement and limits the movement range of the slider. By providing a ring, the slider and the detection box have a higher connectivity and will not swing during movement. By providing a tooth plate, the support plate has a gear-driven mechanism, so that the cable protective cover on the support plate can be repeatedly operated frequently.

[0004] Although the above-mentioned existing technology can realize the wear resistance detection of the cable wear-resistant layer, the overall flexibility is poor. It can only perform friction detection on a single surface of the cable at a time, ignoring the overall wear resistance of the cable when it is rubbed in different directions, thereby affecting the comprehensiveness of the wear resistance detection. Therefore, it does not meet the existing needs. In this regard, we propose a wear resistance detection device for cable production. Summary of the invention

[0005] The purpose of the present invention is to provide a wear-resistant detection device for cable production, so as to solve the problem that the wear-resistant detection device proposed in the above background technology can only perform friction detection on a single surface of the cable at a time, ignoring the overall wear resistance of the cable when it is rubbed in different directions.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wear-resistant detection device for cable production, comprising a base, a groove is arranged at the middle position of the upper end surface of the base, a mounting frame is installed inside the groove, a friction roller is installed inside the mounting frame, and the friction roller is rotatably connected to the mounting frame, a support seat is fixedly installed at the bottom of the groove, the bottom of the mounting frame extends to the inside of the support seat, and the mounting frame and the support seat are slidably matched, a pressure sensor is installed between the mounting frame and the support seat, a lifting seat is installed on both sides of the upper end surface of the base, a cable clamping cylinder is installed at the upper end of the lifting seat, and the cable clamping cylinder is connected to the lifting seat through a bearing, and a driving device is provided at the upper end of the lifting seat.

[0007] Preferably, the output end of the pressure sensor is connected to the input end of a single-chip microcomputer, and the single-chip microcomputer has a built-in timing module.

[0008] Preferably, a first motor is fixedly mounted on one end of the mounting frame, and an output shaft of the first motor is connected to one end of the friction roller via a coupling, and an input end of the first motor is connected to the single-chip microcomputer.

[0009] Preferably, lifting cavities are provided on both sides inside the base, the lower end of the lifting seat extends into the lifting cavity, and the lifting seat and the lifting cavity are slidably limited, a second motor is installed below the lifting cavity, and the output shaft of the second motor is installed with a screw extending into the lifting seat.

[0010] Preferably, the driving device includes a transmission cavity, which is arranged at a middle position between the lifting seat and the cable clamping cylinder, and a driving gear driven by a servo motor is arranged at the lower end of the transmission cavity, and a gear ring is arranged at one end of the cable clamping cylinder located inside the transmission cavity, and the gear ring is meshed and connected with the driving gear.

[0011] Preferably, clamping plates are symmetrically installed on both sides of the cable clamping cylinder, and adjusting wheels are provided on both sides of the cable clamping cylinder. A stud is installed at one end of the adjusting wheel, the stud is threadedly connected to the cable clamping cylinder, and one end of the stud is connected to the clamping plate through a bearing.

[0012] Preferably, a rubber lining is bonded and fixed to the inner wall of the clamping plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In terms of detection method, the present invention utilizes the high-speed rotation of the friction roller to consume the cable. By fixing the two ends of the cable in the cable clamping cylinder, it is ensured that the cable clamping cylinder straightens the cable, and then the second motor is turned on, and its output shaft mobilizes the stud to rotate. Under the friction between its external thread and the screw hole in the lifting seat, the rotational motion is converted into linear motion, thereby driving the straightened cable to descend until it contacts the friction roller and forms a downward force above the friction roller. The pressure sensor inside the support seat can detect the pressure value in real time. After reaching the set value, the second motor is stopped, and the first motor is turned on at the same time to drive the friction roller to rotate at a high speed, so as to realize the friction consumption of the cable wear-resistant layer. As the movement progresses, the thickness of the wear-resistant layer will gradually decrease, resulting in a gradual decrease in the force applied to the friction roller. When the pressure value detected by the pressure sensor is lower than the set value, the first motor is turned off, and the friction consumption time is calculated at the same time, thereby obtaining the friction performance of the cable wear-resistant layer.

[0014] 2. The present invention is provided with a rotatable cable clamping cylinder. During the wear resistance detection process, the servo motor at the upper end of the lifting seat is turned on, and the output shaft of the servo motor will drive the driving gear to rotate slowly, and the cable clamping cylinder is driven to rotate under the engagement of the toothed ring on the outer wall of the cable clamping cylinder, thereby driving the cable clamped inside to rotate. During the contact with the friction roller, the contact position is continuously changed, ensuring that all parts of the cable can be evenly subjected to the wear test, avoiding local excessive wear or insufficient testing due to fixation, thereby improving the accuracy and reliability of the wear resistance detection. Compared with the traditional manual change of contact position or static detection method, this design significantly improves the detection efficiency.

[0015] 3. The present invention is provided with a cable clamping cylinder. After the cable passes through the interior of the cable clamping cylinder, the user can rotate the adjusting wheel to drive the stud equipped with the clamping plate to rotate. Under the friction between the stud and the outside of the cable clamping cylinder, the rotational motion is converted into linear motion, so that the clamping plate continuously approaches the cable until it forms a tight fit with the cable, thereby ensuring the fixing effect of the cable.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1-5 , an embodiment of the present invention: a wear-resistant detection device for cable production, comprising a base 1, a groove 2 is arranged at the middle position of the upper end surface of the base 1, a mounting frame 3 is installed inside the groove 2, a friction roller 4 is installed inside the mounting frame 3, and the friction roller 4 is rotatably connected to the mounting frame 3, a support seat 13 is fixedly installed at the bottom of the groove 2, the bottom of the mounting frame 3 extends to the inside of the support seat 13, and the mounting frame 3 and the support seat 13 are slidably matched, a pressure sensor 14 is installed between the mounting frame 3 and the support seat 13, a lifting seat 6 is installed on both sides of the upper end surface of the base 1, a cable clamping cylinder 7 is installed at the upper end of the lifting seat 6, and the cable clamping cylinder 7 is connected to the lifting seat 6 through a bearing, the output end of the pressure sensor 14 is connected to the input end of the single-chip microcomputer, and the single-chip microcomputer has a built-in timing module, a first motor 5 is fixedly installed at one end of the mounting frame 3, and the output shaft of the first motor 5 is connected to one end of the friction roller 4 through a coupling, and the input end of the first motor 5 is connected to the single-chip microcomputer.

[0020] When in use, by fixing both ends of the cable in the cable clamping tube 7, ensuring that the cable clamping tube straightens the cable, then turning on the second motor 10, its output shaft drives the screw 12 to rotate, and the friction between its external thread and the internal screw hole of the lifting seat 6 converts the rotational motion into linear motion, thereby driving the straightened cable to descend until it contacts the friction roller 4 and forms a downward force above the friction roller 4. The pressure sensor 14 inside the support seat 13 can detect the pressure value in real time. After reaching the set value, the second motor 10 is stopped, and the first motor 5 is turned on at the same time to drive the friction roller 4 to rotate at high speed, thereby realizing the friction consumption of the cable wear-resistant layer. As time goes by, the thickness of the wear-resistant layer will gradually decrease, causing the force applied to the friction roller to gradually decrease. When the pressure value detected by the pressure sensor 14 is lower than the set value, the first motor 5 is turned off, and the friction consumption time is calculated at the same time, thereby obtaining the friction performance of the cable wear-resistant layer.

[0021] See also Figure 1 and Figure 3, lifting cavities 11 are provided on both sides of the interior of the base 1, the lower end of the lifting seat 6 extends into the interior of the lifting cavity 11, and the lifting seat 6 and the lifting cavity 11 are limited by sliding, and a second motor 10 is installed below the lifting cavity 11, and the output shaft of the second motor 10 is installed with a screw 12 extending into the interior of the lifting seat 6. The second motor 10, its output shaft drives the screw 12 to rotate, and the rotational motion is converted into linear motion under the friction between its external thread and the internal screw hole of the lifting seat 6, thereby driving the straightened cable to descend until it contacts the friction roller 4. By recording the time consumed by friction and combining with known friction conditions, such as the material and rotation speed of the friction roller, the friction performance parameters of the cable wear-resistant layer, such as wear-resistant life and wear-resistant coefficient, can be easily calculated, which provides an important basis for the quality control, material research and development and improvement of the cable.

[0022] See also Figure 1 and Figure 4 A driving device is provided at the upper end of the lifting seat 6, and the driving device includes a transmission cavity 16, which is arranged at the middle position inside the lifting seat 6 and the cable clamping cylinder 7. A driving gear 18 driven by a servo motor is provided at the lower end of the transmission cavity 16. A gear ring 17 is provided at one end of the cable clamping cylinder 7 located inside the transmission cavity 16, and the gear ring 17 is meshed with the driving gear 18. During the wear resistance detection process, by turning on the servo motor at the upper end of the lifting seat 6, the output shaft of the servo motor will drive the driving gear 18 to rotate slowly, and the cable clamping cylinder 7 is driven to rotate under the meshing of the gear ring 17 on the outer wall of the cable clamping cylinder 7, thereby driving the cable clamped inside to rotate. In the process of contacting with the friction roller, the contact position is continuously changed, ensuring that each part of the cable can be evenly subjected to the wear test, avoiding the situation of excessive local wear or insufficient testing due to fixation.

A stud 15 is installed at one end of the adjusting wheel 9. The stud 15 is threadedly connected to the cable clamping cylinder 7, and one end of the stud 15 is connected to the clamping plate 8 through a bearing. A rubber lining 19 is adhered and fixed to the inner wall of the clamping plate 8. After the cable passes through the inside of the cable clamping cylinder 7, the user can rotate the adjusting wheel 9 to drive the stud 15 equipped with the clamping plate 8 to rotate. Under the friction between the stud 15 and the outside of the cable clamping cylinder 7, the rotational motion is converted into linear motion, so that the clamping plate continuously approaches the cable until it forms a tight fit with it, thereby ensuring the fixing effect of the cable.
