Description
Technical field：
The utility model belongs to cable detection field, and in particular to a kind of cable cleat, for realizing cable high-temperature pressure
The nondestructive measurement of impression processing and impression.
Background technique：
Cable high-temperature pressure testing is relatively conventional one of the inspection project of cable, refers to cable insulation or protective case one
Determine after being deformed at temperature by external mechanical power, the recovery capability when removing external force, reducing temperature, for examining cable insulation
The compressive property of material at high operating temperatures, it is one of the common counter for judging wire and cable product quality.
Wire and cable Apparatus for Pressure at high-temp method is according to GB/T2951.31-2008/IEC60811- both at home and abroad at present
3-1：1985《Cable and optical cable insulating and protection cover material GENERAL EXPERIMENTATION-Apparatus for Pressure at high-temp-cracking resistance test》It carries out
Test operation.I.e.：3 adjacent samples are intercepted from length about 250~300mm subject insulated wire cores sample section, each sample is long
Degree is about 50~100mm；Push type broach is made of the rectangular blade that knife edge thickness is 0.7 ± 0.01mm, along perpendicular to sample axis
Direction applies pressure, and blade should be vertical with the axis of sample；Sample heats in air -oven, after heating, in pressure
Effect is lower cooling rapidly；It is measured immediately after cooling, cuts two examinations at impression and near impression perpendicular to axis direction
Piece, depth of cup are the difference of the measured value of two test pieces under the microscope.The evaluation of sample of cable test result：From each sample
Impression median is measured in three test pieces cut, the 50% of sample insulation thickness average value should be not more than.But above-mentioned measurement
There are many problems in the process：In Indentation Process, sample places whether horizontal, whether the edge of a knife is vertical all by shadow with sample axis
The form for ringing edge of a knife impression, that is, not can guarantee the form of impression；Measurement method needs, which take a significant amount of time, to be manually sliced, and is imitated
Rate is low and material rebounds, blade cutting test material excessively high to the requirement of artificial microtomy can be caused also to hold after decompression for a long time
Easily cause error；It needs tester to find impression thinnest point and sample axis point of proximity insulation thickness on projector and surveys
Amount, it is more difficult to realize and be accurately positioned；Test is that have loss measurement, does not have the condition of repeated measurement, so that test result accuracy is not
It is high, it is difficult to realize high-acruracy survey.
Therefore we need to design cable impression Auto-Test System, including cable cleat, laser ranging system, movement control
System processed, data acquisition and analysis system etc..Sample of cable is fixed on progress impression processing on fixture；After impression, electricity will be accompanied
The fixture of cable sample is fixed on the sliding block of guide rail, is moved using Serve Motor Control guide rail, its level is made to pass through laser sensing
Below device；Measure at cable impression using laser sensor range accuracy high feature；Using computer to entire test
Process carries out control and data processing, realizes the automatic test of cable impression.Therefore it designs a kind of for measuring different line footpath electricity
The fixture of cable sample impression is the link of the system most critical.
And existing cable cleat volume is big, not easy to install, complicated for operation and be chiefly used in cable surface insulating materials
Protection.It is screwed by lower arcuate intermediate plate to clamp cable, but arcuate structure cannot make cable be fixed on it well
In, shaking of the cable between two intermediate plates can be caused, and fixture upper and lower surface is closed, and cannot achieve to sample of cable surface
Impression processing and the measurement of impression.
Summary of the invention：
The purpose of this utility model is the defect of the defect and deficiency and existing fixture for above-mentioned measurement method, is mentioned
Cable cleat device that is small in size, easy to operate for one kind, being easily installed and fixed sample of cable can be stablized.
The utility model is solved the above problems by following technical proposals：A kind of cable cleat device, it include V-shaped platform,
Fixed link, torsional spring, connecting rod and two upper holder blocks.V-shaped platform surface is smooth, and there is a certain slope in upper surface, in v-shaped slot there are four
Cylindrical hole, upper surface middle position is there are four cylinder boss, and there are six small cylindrical tanks for lower surface, and V-shaped platform side surface one end is provided with
One tapped through hole, and there are two square boss；Fixed link both ends are smooth, and centre has screw thread, connect with V-shaped platform；Upper holder block
With V-shaped platform equivalent width, there is hole in side, and the middle position of lower surface is provided with v-shaped mouth, corresponding up and down with the v-shaped slot of V-shaped platform, and two
By a connecting rod connection between a upper holder block, allows two upper holder blocks to synchronize rising and fall；Torsional spring coil diameter is than solid
Fixed pole diameter is bigger, and can rotate around fixed link, and one end of torsional spring is connect with upper holder block, and the other end and V-shaped platform side surface are rectangular
Boss is fixed；Initial state, two upper holder blocks are pressed on V-shaped platform surface, lift upper holder block, and torsional spring is rotated around fixed link, will be electric
Cable is placed in v-shaped slot, unclamps upper holder block, and due to the effect of torsional spring power, upper holder block falls, and the v-shaped slot cooperation with V-shaped platform is played solid
Determine the effect of cable.
The mechanical structure of the utility model is easy to operate, it is contemplated that entire fixture will be put into 80 degrees Celsius of air -oven
4 hours are heated, also needs to be made with cold water sample cooling after heating, comprehensively considers above-mentioned two o'clock, our uses to fixture
Material also requires, it is desirable that the antirust of metal used, it is heat-resist, and apparent deformation, therefore above-mentioned folder will not occur after heating
Have us and uses the material of stainless steel.Simultaneously in view of the line footpath of wire and cable sample is differed from 1mm to 10mm, so we need
They are classified, different line footpaths requires difference to the depth and width of v-shaped slot, so we need to carry out two sets of v-shaped
Groove depth, v-shaped platform of different size, but the overall width of V-shaped platform is constant, the electricity for the different line footpaths that are fixedly clamped by upper holder block
Line sample of cable.Wire and cable is stably fixed on the mechanical clamp of the utility model, wire and cable is not being changed
In the case where sample position, the depth of wire and cable impression is measured, prevented that human factor and test method factor introduce is
System error, substantially reduces detection time, reduces cost of labor, save experimentation cost, realizes nondestructive inspection (NDI), above-mentioned to be
The advantages of for the utility model fixture and the positive effect played.
