Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for wire and cable testing, and in particular to a height measuring device for auxiliary wire and cable testing. Background Art

[0002] Wires and cables are important components of power transmission and communication. They are responsible for the transmission of electric energy and information. The quality of wires and cables directly affects the quality of power transmission and communication, and is closely related to the reliability of equipment and systems. Therefore, before leaving the factory, wires and cables need to undergo routine, sampling, and type tests such as electrical performance tests, thermal performance tests, single-wire vertical combustion tests, sheath mechanical performance tests, and structural dimension inspections. In the sheath mechanical performance test of wires and cables, the sheath of the cable needs to be cut for testing.

[0003] In the process of the inventor's daily use of cable die chipping equipment to obtain chipping samples, the inventor found that when the existing cable die chipping equipment is in use, the equipment cannot ensure that the sample and the blade are parallel when the cable is clamped on the fixture, and thus the thickness requirement of the chips cannot be controlled. Since the sample is often affected by the uneven height of the instrument, it is necessary to measure the sample height and the distance between the sample and the blade for height adjustment. However, the current measurement method is complicated and time-consuming to process, which affects the feedback speed of the chip height data and will affect the chip thickness.

[0004] When the inventor uses a single vertical burning device to perform single vertical burning of wires and cables on a daily basis, it is necessary to obtain the results after burning, wherein it is necessary to measure the burning length of the single wire and cable after it is placed vertically. Most of the existing single vertical burning devices have a ruler set on a bracket on one side of the burning station, and the operator obtains the burning length data through visual inspection. The final test is not accurate enough, which affects the test results.

[0005] In view of this, how to research and design a universal device that can be used in various tests of wires and cables as a measurement function has become a topic to be studied and solved by the present utility model. Utility Model Content

[0006] The purpose of the utility model is to provide a height measuring device for auxiliary use in wire and cable testing, so as to improve efficiency, increase the accuracy of obtaining samples and data, and meet multi-purpose needs.

[0007] In order to achieve the above-mentioned object, the utility model proposes a height measuring device for auxiliary use in wire and cable testing, the height measuring device comprising a base, a leveling component, a scale component and an upper cover plate;
