Plate 15 is fixed on upper mounted plate 111 and bottom plate 112, and one is moved up or move down so as to accurately measure one-dimensional adjusting bracket 14
Secondary distance, it is ensured that have to the multistage insulating sheath test sample that small line footpath cable insulating sheath obtained after repeatedly cutting into slices
Identical length.
The small line footpath cable insulating sheath slicing device being related to using the application is joined to small line footpath cable insulating sheath
Counting the correlation step tested is:
Step 1, the one section small line footpath cable of interception, the core in this section small line footpath cable is pulled out, one section of small line is obtained
Footpath cable insulating sheath, then this section small line footpath cable insulating sheath is cut into slices, to obtain multistage insulating sheath test sample.
Step 2, fixed small line footpath cable insulating sheath:Selection has what is be adapted with small line footpath cable insulating outer diameter sheath
The sheath retainer ring 20 of supported hole 21, the sheath retainer ring 20 is placed on the first installing plate 12, and the stubborn bolt of hand is tightened,
So that sheath retainer ring 20 is fixed on the first installing plate 12;By the upper end of small line footpath cable insulating sheath from sheath retainer ring 20
Supported hole 21 in pass, by the lower end fixed clamp of small line footpath cable insulating sheath cable clamp gripping member 30 fixing groove 31
In, because supported hole 21 is oppositely arranged and is coaxially set about 31 with fixing groove, therefore after small line footpath cable insulating sheath is fixed
For the state placed vertically, and supported hole 21 has certain length in the vertical direction, it is ensured that small line footpath cable insulating sheath
Will not be crooked.
Step 3, by the power switch 110 on lower house 80, switch on power, rotation speed governing knob 120, by the rotation of motor 50
Rotary speed is transferred to appropriate speed, then motor 50 drives scroll chuck synchronously to rotate, and scroll chuck drives small line footpath cable insulating
Sheath synchronously rotates;Due to the limitation of sheath retainer ring 20, small line footpath cable insulating sheath can rotate vertically, to ensure cutting
The even uniform of end face.
Step 4, forward passage blade support 40, blade support 40 is synchronously moved forward with cutting blade, to cut rotation
In small line footpath cable insulating sheath;Because the angle α between blade and horizontal plane is 10 °, therefore small line footpath cable insulating sheath
Under the cutting of low-angle blade, cutting end face is because the angle of inclination of blade is close to level, therefore cutting end face will not hairiness
Thorn, and cutting end face it is vertical with small line footpath cable insulating sheath, be not in larger angle of inclination;So far, small line footpath cable
The upper strata end face of insulating sheath has been cut out, and the upper strata end face is also the upper strata end face of insulating sheath test sample.
Step 5, press power switch 110, motor 50 and stop operating, blade support 40 is moved rearwards by, resetted, make digital display
Numerical value on the digital display screen of slide measure 70 is reset;Swing handle 62, moves down one-dimensional adjusting bracket 14, according to digital display vernier
Numerical value can intuitively judge the descending distance of one-dimensional adjusting bracket 14 on the digital display screen of slide calliper rule 70, and the numerical value is:Sheath retainer ring
20 and the length of the descending distance of blade and insulating sheath test sample to be intercepted;Treat that one-dimensional adjusting bracket 14 drives sheath
Retainer ring 20 and blade are moved down after suitable distance, and repeat step 4 is exhausted from small line footpath cable by insulating sheath test sample
Cut on edge sheath.Therefore, the length of each section of insulating sheath test sample after cutting can be ensured by electronic digital indicator 70
Degree is consistent, and meets the requirement of tester;Meanwhile, the upper strata end face and lower floor's end face of insulating sheath test sample all with insulation
Sheath test sample is perpendicular, flatness is high, deform very small, impulse- free robustness, as shown in Figure 6.
Step 6, the insulating sheath test sample cut is taken and tested on dependence test instrument, and obtain related ginseng
Number.
In summary, the small line footpath cable insulating sheath slicing device that the application is related to is using fixed small line footpath cable insulating
The mode of sheath, circumgyration incision and low-angle section, cuts into slices to small line footpath cable insulating sheath, simple to operate
Fast, the cutting end face after cutting is smooth, and the length of each section of insulating sheath test sample of interception is uniform, to small line footpath cable
The loss of insulating sheath is small, so that the test influence control of the small line footpath cable insulating sheath parameter by human factor on after is arrived
It is minimum.Especially, relative to cable in the prior art is motionless, for the cutting mode of blade rotation translation, the application is using small
Line footpath cable insulating sheath is clamped by scroll chuck, and motor 50, which is rotated, causes small line footpath cable insulating sheath in sheath retainer ring 20
Middle rotation, because the application coordinates multiple sheath retainer rings 20, it is ensured that the diameter of supported hole 21 can coordinate small line footpath cable exhausted
The external diameter of edge sheath is cut;To when promoting blade support 40 close to small line footpath cable insulating sheath direction, blade is to rotation
In small line footpath cable insulating sheath cut;It is small due to supporting small line footpath cable insulating sheath using sheath retainer ring 20
The relative cutting end face of line footpath cable insulating sheath is vertical, therefore the plane cut out is smooth, insulating sheath test sample upper and lower end face
The depth of parallelism is higher, will not flatten small line footpath cable insulating sheath, and it finds particular application to the smaller small line footpath of cutting diameter
Cable insulating sheath, minimum diameter is up to 0.5mm.
So, the utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
God and all equivalent modifications completed under technological thought or change, should be covered by claim of the present utility model.
