Description

Technical Field

[0001] The utility model relates to the technical field of cable quality detection, in particular to a cable quality detection device. Background Art

[0002] Cables are usually made of several or several groups of wires (at least two wires in each group) twisted together like ropes. Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering. The cable has the characteristics of being powered inside and insulated outside. When testing cables, quality testing devices are needed.

[0003] Announcement No. CN219957148U discloses a surface quality detection device for wires and cables, including a mounting table, a mounting groove is provided on the top of the mounting table, a cable body is arranged on the inner side of the mounting groove, fixed blocks are fixedly installed on both sides of the top of the mounting table, a mounting frame is fixedly installed on the top of the fixed block, a threaded sleeve is fixedly installed on the top of the mounting frame, an extrusion screw is connected to the internal thread of the threaded sleeve, a mounting plate is fixedly installed on the bottom of the extrusion screw, a pressure sensor is fixedly installed on the bottom of the mounting plate, a pressure block is fixedly installed on the bottom of the pressure sensor, the pressure block is located above the mounting groove, a side panel is fixedly installed on the left side of the mounting table, a pressure display is arranged on the front of the side panel, and the output end of the pressure sensor is electrically connected to the input end of the pressure display. Although this quality inspection device solves the problem that the existing cable surface quality inspection generally relies on workers to observe whether the cable surface is damaged, and does not have the ability to detect the pressure-bearing capacity of the cable surface, which affects the later use of the cable, the quality inspection device mainly relies on the extrusion plate and the limit plate to directly squeeze and fix the cable body. This method often causes the cable surface to be worn or damaged due to excessive friction. This damage not only affects the appearance quality of the cable, but also may damage the internal structure of the cable, thereby reducing the service life and safety of the cable. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a cable quality detection device, comprising a mounting table, a mounting frame is fixedly installed on the top surface of the mounting table, a screw rod is penetrated through the top surface of the mounting frame, the bottom end of the screw rod is rotatably connected to a mounting plate, a pressure sensor is fixedly installed on the bottom surface of the mounting plate, a cylinder is fixedly installed on the side of the mounting table, an extrusion plate is installed on the output end of the cylinder, a short plate is fixedly installed on the side of the extrusion plate, a roller is rotatably connected to the surface of the short plate, a ball is rollingly connected to the surface of the roller, an inner cavity and a cable cavity are opened inside the mounting table, a cable body is placed inside the cable cavity, a partition is fixedly installed on the inner wall of the inner cavity, a threaded rod is penetrated through the interior of the partition, the top end of the threaded rod is rotatably connected to a long plate, and a protective pad is fixedly installed on the top surface of the long plate.

[0006] Preferably, the long board is slidably connected to the inner wall of the inner cavity, and the protective pads are arranged at equal distances on the top surface of the long board.

[0007] Preferably, the interior of the mounting frame is provided with threads, and the threads are meshed with the lead screw.

[0008] Preferably, the interior of the partition is provided with threads, and the threads are engaged with the threaded rod.

[0009] Preferably, the balls are arranged at equal distances on the surface of the drum.

[0010] Preferably, the surface of the mounting plate is provided with a decontamination mechanism, the decontamination mechanism comprises an annular groove, the annular groove is provided on the surface of the mounting plate, a slide plate is slidably connected to the inner wall of the annular groove, a friction pad is fixedly installed on the bottom surface of the slide plate, an extension block is fixedly installed on the surface of the mounting frame, a vertical plate is slidably connected inside the extension block, and the vertical plate is fixedly connected to the slide plate. Here, the detection accuracy can be improved.

[0011] Preferably, the friction pad is made of polyester fiber, thereby increasing the service life of the friction pad.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, during actual use, the cable body to be inspected for quality is placed in the cable cavity, and then the screw rod is rotated. At this time, since a thread is provided in the mounting frame, the screw rod moves downward in the mounting frame, and then the screw rod drives the mounting plate and the pressure sensor to move downward until the pressure sensor is against the surface of the cable body, and then the cable body is pushed. At this time, the pressure value of the pressure sensor and the degree of deformation of the cable body surface can be used to judge whether the surface pressure bearing capacity of the cable body meets the standard. At the same time, when fixing the cable body, the extrusion plate is driven to move by the cylinder, and the extrusion plate then drives the roller to squeeze the cable body. At this time, the cable body can be fixed in the cable cavity. At the same time, the friction force applied to the cable body can be reduced by the provided ball bearings. In this way, after the cable body is fixed, the resistance of the cable body passing through will not increase, thereby preventing the cable body from being worn during movement, and the height of the protective pad can also be freely adjusted. The utility model can reduce the friction force applied to the cable body by setting a ball, thereby avoiding the surface wear of the cable body due to excessive friction when fixing the cable body. Compared with the prior art that directly squeezes and fixes the cable body through an extrusion plate and a limit plate, this point can more effectively protect the surface of the cable body and reduce the damage to the cable body during the detection process. Moreover, through the adjustable height design of the protective pad, the technology can adapt to cable bodies of different sizes and diameters. The flexibility and adaptability of this design are better than the method of fixing the cable body through a fixed installation groove and a limit plate in the prior art, and can better meet the diverse cable detection needs.

[0014] 2. In the utility model, during actual use, in the process of the mounting plate driving the pressure sensor to move downward, the mounting plate can synchronously drive the slide plate to move, and the slide plate can then drive the vertical plate downward to slide in the extension block, and then the slide plate can drive the friction pad to move downward, so that after the pressure sensor is against the cable body, the friction pad can also synchronously against the cable body. At this time, in the process of the cable body continuing to enter, the friction pad can rub the surface of the cable body. The utility model can remove dust, oil and other impurities on the surface of the cable body before detection through the friction of the friction pad, which can reduce the influence of these external factors on the pressure test results, thereby improving the accuracy and reliability of the detection, and the friction pad can reduce the stains and particles on the surface of the cable body from entering the detection device, reduce the wear on the pressure sensor and other mechanical components, extend the service life of the equipment, and has high practicality.

At this time, the pressure value of the pressure sensor 5 and the deformation degree of the surface of the cable body 13 can be used to judge whether the surface pressure bearing capacity of the cable body 13 meets the standard. At the same time, when fixing the cable body 13, the cylinder 6 drives the extrusion plate 7 to move, and the extrusion plate 7 then drives the roller 9 to squeeze the cable body 13.
