Description

In length and breadth to the spiral cable cutter

Technical field

The utility model relates to a kind of stripping instrument of opening of cable, particularly a kind of can be in length and breadth to open that the wire stripping cable can put in a skylight again in length and breadth to the spiral cable cutter.

Background technology

Along with progress of science and technology; expanding economy; electric power, communication line almost spread all over each corner of motherland; often need carry out the connection of cable at laying electric power, communication line work progress; processing to cable also usually takes place in daily electric power, communication line maintenance work; because the protective layer of cable is thicker; generally make by hand and open the wire stripping cable with the stripping instrument of opening of knife and pliers type; more time-consuming taking a lot of work; thereby and all can't be accurately open the stripping degree of depth to degree and cause possible cable quality problem, have the hidden danger of safety and quality.

Vertical cable cutter that the applicant applies for before this, can not promptly can only vertical or horizontally open stripping to the cable blank to cable cutter in length and breadth, the repairing to fault wire brings difficulty like this.

Summary of the invention

Problem to be solved in the utility model is: propose a kind of convenient, fast instrument of stably opening the wire stripping cable that reaches.Can open the wire stripping cable and put in a skylight from both direction in length and breadth, and can more accurate control feed in length and breadth to the spiral cable cutter.

The technical solution of the utility model is: a kind of in length and breadth to the spiral cable cutter, comprise knife rest, knife rest comprises clamping device, running gear and location feed governor motion, described location feed governor motion comprises two cuttves: in length and breadth to cutter and circular knife, lay respectively at the both sides of knife rest in length and breadth to cutter and circular knife, two cuttves are by adjusting nut, regulate turncap, adjustment screw, broach shell, stage clip, thrust screw and steering tiller are formed, regulate in the turncap and debug the joint nut, debug the joint screw in the adjusting nut, adjustment screw, steering spindle is connected in turn with blade, broach shell and stage clip all are enclosed within on the blade, broach shell is positioned at the side near steering spindle, have a through hole on the steering spindle, steering tiller contacts with blade by through hole and can rotate to the diameter of axle to rotation; Clamping device is positioned at the centre of knife rest, comprises interior axle, binding nut and screw, and the centre of knife rest has a through hole, and interior axle passes through hole and makes through hole be positioned at the axle middle part, and interior axle top is with binding nut, passes through screw; Running gear comprises roller, and roller housing is in interior axle bottom.

As a kind of improvement project of the present utility model, described running gear also comprises bearing, back-up ring and screw, and in interior axle bottom, shield ring sleeve is on screw by screw for bearing, and back-up ring is positioned at the bearing bottom, and bearing, back-up ring and screw all are positioned at roller inside.

As a kind of improvement project of the present utility model, the anglec of rotation of described circular knife blade is 60 ° of angles, just can produce the cut of twisted shape like this when cutting, conveniently puts in a skylight.

As a kind of improvement project of the present utility model, described blade both sides cutting edge becomes 12 ° of angles, makes the blade cutting edge position sharper.

As a kind of improvement project of the present utility model, be carved with annular knurl formula decorative pattern on the described adjusting turncap, make the frictional force of holding when regulating turncap strengthen, grip easily and good hand touch.

As a kind of improvement project of the present utility model, described clamp system also comprises a pad, and axle top in pad is enclosed within is between binding nut and knife rest, interior shaft connection place.

The utlity model has simple in structure, easy to make, multi-functional, open advantages such as the wire stripping cable is time saving and energy saving, and, be specially adapted to the cable blank because circular knife is installed, be suitable for multiple different size, the electric power of kind, the repairing of the communications cable.

Description of drawings

Fig. 1 is the utility model vertical profile structural representation.

Embodiment

Embodiments of the present invention is further illustrated below in conjunction with accompanying drawing.

Referring to Fig. 1, be equipped with respectively in length and breadth to cutter and circular knife at knife rest 1 two ends, andinterior axle 17 is positioned at the centre ofknife rest 1.

Described location feed governor motion comprises in length and breadth to cutter and circular knife, wherein in length and breadth to cutter by regulatingturncap 11, adjustingnut 2,adjustment screw 12,broach shell 4,steering tiller 7,thrust screw 6 andsteering spindle 3 are formed, regulate and debugjoint nut 2 in theturncap 11,debug joint screw 12 in the adjustingnut 2,adjustment screw 12,steering spindle 3 is connected in turn withblade 13,broach shell 4 is enclosed within on theblade 13, have a through hole on thesteering spindle 3, steering tiller 7 contacts with blade by through hole and can rotate to the diameter of axle to the half-twist angle,thrust screw 6 is by twisting, can contact withblade 13, thereby make feed apart from keeping stable.When vertically opening stripping, blade is parallel with optical cable; When cross-sectional, blade will rotate to vertical with optical cable.In length and breadth to the cut of cutter cutting linearly type or arc.

The circular knife internal structure is with basic identical to cutter in length and breadth, but with in length and breadth to cutter different be that the steering tiller on the circular knife can rotate to the diameter of axle to the rotation hexagonal angle, thereby makes blade when rotation become 60 ° of angles with cable, the cut that cuts out like this is twisted shape, is convenient to put in a skylight.

Described clamping device is positioned at the top ofaxle 17, its structure is: be withbinding nut 8 oninterior axle 17 tops, and it is fixing byscrew 10, the middle part ofknife rest 1 has a through hole,interior axle 17 passes through hole and makes through hole be positioned at the middle part ofaxle 17,axle 17 diameters in the width of through hole is slightly larger than, the length of through hole is greater thaninterior axle 17 diameters, whenbinding nut 8 is not tightened, inaxle 17 can be in through hole move left and right alongst, regulate the feed distance, also be provided withpad 9 betweenbinding nut 8 and theknife rest 1, during with assurance screw downclips jack panel 8, can well fix the cable betweenknife rest 1 and theroller 16, the clamping device of this structure is compared with the clamping device of gear-like, and its advantage is to be difficult for skidding.

Described running gear is positioned at the bottom ofaxle 17, its structure is:interior axle 17 bottoms are withroller 16,roller 16 inside are provided with bearing 14 and back-upring 15,axle 17 bottoms inbearing 14 is fixed on byscrew 18, and back-upring 15 is positioned at bearing 14 bottoms and is enclosed within on the screw 18.The running gear that adds upper bearing (metal) 14 is compared with running gear in the past, and the frictional force during promotion can reduce a lot, and this just makes that opening the stripping resistance descends greatly.

During use, at first estimate the thickness of cable protection layer according to the external diameter of cable, as will be in length and breadth to cutting, cable is placed in length and breadth between cutter androller 14, regulatefeed adjustment screw 12, fix to clampturncap 8, rotate adjustingnut 2, so thatblade 13 embeds the degree of depth of cable regulation, pulling knife rest 1 promptly realizes vertically opening stripping; Will laterally open stripping only needs to rotatesteering tiller 7, and rotatingturret 1 gets final product then.As will be to the cable blank; to sandwich cable between circular knife and theroller 14; estimate the thickness of cable protection layer again according to the external diameter of cable; regulate the feed adjustment screw; fix to clamp knob, rotate adjusting nut, just blade embeds the degree of depth of cable regulation; swivelling tool-holder can realize that spiral opens stripping (being blank).
