A kind of detent mechanism of aluminum stranded wire stripping device
Technical field
The present invention relates to a kind of aluminum stranded wire stripping device, particularly a kind of detent mechanism of aluminum stranded wire stripping device.
Background technology
In the prior art, when cable or its outsourcing insulation are carried out wire stripping, generally take pliers, cutter or cut, when stating instrument strip cable line in the use, all dynamics are used with feeling by the operator, being easy to cause peel force to kick the beam can't be with its strip off, or the overweight aspect that causes not needing to peel off of peel force also is removed, so the occurrence rate of substandard products is higher; In addition, for the operator, because the fail safe of instrument is low, misoperation is easy to cause personnel's incised wound.For addressing the above problem, people have developed some special wire strippers, with reference to application number is 200720005062.7 open Chinese patents " high-voltage insulating wire wire stripper ", though the wire stripper of this structure partly improves cutter, but do not relate to for the fixing of cable part, unavoidable in the wire stripping process, deviation takes place in the position of cable, thus the accuracy of influence cutting.
Summary of the invention

Preferably, described body is provided with fixed block, and described guide wheel is connected on the described fixed block by described guide wheel pin.
Preferably, offer spacing hole on the described fixed block, described guide wheel pin is arranged in the described spacing hole.
Preferably, be connected with spring in the described spacing hole, an end of described spring is connected with described fixed block, and the other end is connected with described guide wheel pin.
Preferably, described roller is fixed on the described body by needle roller.
Preferably, described roller is provided with two.
Because technique scheme utilization, the present invention compared with prior art has following advantage: the present invention is attached thereto holder and connects by being arranged on detent mechanism on the cutting part, makes user's more convenient to operate and safety when wire stripping.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
A kind of aluminum stranded wire stripping device shown in Fig. 6,7 comprises the holder 1 that is used for fixing stripped line line body, the cutting part 2 that is used for the line body is carried out wire stripping or cutting.
Shown in Fig. 1~3, holder 1 comprises a pair of formwork 3, and a pair of formwork 3 is connected with the fixed die 5 that is complementary with the line body profile by formwork pin 4 connection that rotates in the formwork 3.According to the difference of stripped line line body thickness, replaceable different fixed die 5, the external diameter of fixed die 5 is all identical, just realizes that by increasing its thickness the adjusting of its internal diameter comes to be complementary with stripped line line body.Fixed die 5 stretches out holder 1, and the outer surface of fixed die 5 extensions circumferentially offers along it and rolls poor 6.
Holder 1 also comprises and is used for locking mechanism that a pair of formwork is locked mutually, locking mechanism comprises screw 7, is engaged in the nut 8 on the screw 7, screw 7 is connected on the outer peripheral face of a formwork 3 by rotating shaft 9, corresponding screw 7 places are provided with along its block that radially protrudes 10 on the outer peripheral face of another formwork 3, and block 10 is the U font.Handgrip fixed part 11 also is set on the formwork 3, and handgrip 12 has been threaded on the handgrip fixed part 11.
Shown in Fig. 4,5, cutting part comprises body 13, be arranged on cutter 14 on the body 13, be used for holder 1 is connected detent mechanism on the body 13.Wherein: the roller 16 that detent mechanism comprises guide wheel 15, is oppositely arranged with guide wheel 15, the thickness of guide wheel 15 and roller 16 is less than the width of slot rolling 6 on the fixed die 5.Body 13 is provided with fixed block 17, and guide wheel 15 is connected on the fixed block 17 by guide wheel pin 19; 16 on roller is fixed on the body 13 by needle roller 19.
Be provided with the governor motion that is used to regulate cutter 17 extension elongations in the body 13, governor motion comprise the screw rod 20 that is connected with cutter 14, with the screw rod cover 21 that screw rod 20 is complementary, screw rod cover 21 fixes with body 13.Screw rod overlaps 21 external fixation and is connected with the handgrip of operating for the operator 22.
Below the concrete method of operation of present embodiment down of setting forth:
The fixed die 5 that selection and stripped line line body diameter are complementary, formwork 3 is opened by formwork pin 4, offered first screw on the formwork 3, offer second screw on the fixed die 5, first screw with on the corresponding formwork 3 of second screw on the fixed die 5 is connected both by screw.In addition, the internal face of formwork 3 is provided with protuberance 23, and corresponding protuberance 23 places are provided with recess 24 on the fixed die 5, and after fixed die 5 was connected in the formwork 3, protuberance 23 was stuck in fixed die 5 and formwork 3 are completely fixed.
Stripped line line body is placed in the fixed die 5, closes formwork 3, screw rod 20 is rotated in the middle of the U type block 10 by rotating shaft 9, rotation nut 8 makes the bottom surface of nut 8 push against the upper surface of block 10, and formwork 3 is locked.Certainly also be arranged with back-up ring 25 on screw 7, back-up ring 25 is arranged between nut 8 and the block 10, the contact-making surface that increases both makes its locking effect better.Nut 8 may be selected to be wing nut in the present embodiment, makes things convenient for the user to rotate.
Guide wheel on the cutting part 15 and roller 16 are fastened in the slot rolling 6 on the fixed die 5, offer spacing hole 26 on the fixed block 17 in the present embodiment, guide wheel pin 18 is arranged in the spacing hole 26.Be connected with spring 27 in the spacing hole 26, an end of spring 27 is connected with fixed block 17, and the other end is connected with guide wheel pin 18.Like this, when the slot rolling 6 of fixed die 5 was set to 16 on guide wheel 15 and roller at card, guide wheel 15 can be mobile spacing hole 16 in by spring 27, to make things convenient for the location of fixed die 5.Location back guide wheel 15 and roller 16 are in slot rolling 6, and roller 16 is provided with two, as shown in Figure 8.
By the collapsing length of rotary handle 22 adjusting cutters 14, make cutter 14 extend the line body place of stripped line, rotation cutting part 2 carries out wire stripping.When needs cut the line body, only need rotary handle 22, make cutter 14 extend line body inside and get final product, as shown in Figure 9.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
