Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.With
Lower embodiment is used for illustrating the present invention, but is not limited to the scope of the present invention.
See Fig. 1 to Fig. 5, the cutter holder assembly of a kind of wire stripper described in a preferred embodiment of the present invention, including
Support frame 10, support frame 10 is enclosed formed by top board 11, base plate 12 and biside plate 13, is supporting
Framework 10 be provided with two vertically move along it, blade that the edge of a knife is relative, and drive two blade move toward one another
Drive mechanism.
In the present invention, the wire stripping of two blades is controlled by motor 31 with cut-out action, concrete, and drive mechanism includes
The motor 31 being arranged in support frame 10, and driven rotation by motor 31, be there is dextrorotation screw thread and anti-
The screw mandrel 32 of rotation screw thread, the most threaded on two sections of screw threads of screw mandrel 32 have nut 33, by screw mandrel 32
Two ends top board 11 and base plate 12 with support frame 10 respectively is rotationally connected.Concrete, push up at screw mandrel 32
End axially connects a drive pulley 36, by the drive pulley 36 electrical machine belt pulley 37 by Timing Belt with motor 31
Being in transmission connection, when motor 31 rotates, rotation also followed by screw mandrel 32.
Two blades are respectively upper slitter 21, lower cutter 22, and upper slitter 21 connects upper mounted plate 23, upper mounted plate 23
Connect and have upper guide bracket 25, upper guide bracket 25 through screw mandrel 32 and is connected with one of them nut 33；Corresponding,
Lower cutter 22 connects bottom plate 24, and bottom plate 24 connects lower guide bracket 26, is passed by lower guide bracket 26
Screw mandrel 32 is also connected with another one nut 33.So, when motor 31 drives screw mandrel 32 to rotate, on
Guide bracket 25 and lower guide bracket 26 can drive upper slitter 21 to move in the vertical with lower cutter 22 respectively, make upper slitter 21
Move in opposite directions or dorsad with lower cutter 22, make upper slitter 21 and lower cutter 22 realize hemisection, the work entirely cut, unclamp
Process, completes the action of wire stripping, cut-out.
In order to make upper guide bracket 25 move the most in the vertical with lower guide bracket 26, top board 11 of the present invention and base plate
It is also associated with two linear bearings 34 between 12, makes two linear bearings 34 lay respectively at screw mandrel 32 both sides, and make
Two linear bearings 34 extend through guide bracket 25 and lower guide bracket 26.Utilize the two upper guide brackets of linear bearing 34 auxiliary
25 with lower guide bracket 26 linear motion in the vertical, simultaneously work as guide effect.
When, after upper slitter 21 with lower cutter 22 closed amputation electric wire, motor 31 reversion makes upper slitter 21 multiple with lower cutter 22
Position, in order to make upper guide bracket 25 and lower guide bracket 26 that upper slitter 21 can be driven rapidly to reset with lower cutter 22, this
Be arranged with on a bright linear bearing 34 wherein two ends respectively with answering that upper guide bracket 25 and lower guide bracket 26 offset
Position spring 35.After closing with lower cutter 22 because of upper slitter 21, back-moving spring 35 is compressed, when motor 31 inverts
After, back-moving spring 35, under the effect of elastic potential energy, provides thrust to upper guide bracket 25 with lower guide bracket 26, from
And make guide bracket 25 drive rapidly upper slitter 21 to reset with lower cutter 22 with lower guide bracket 26.
In order to make motor 31 can control upper slitter 21 and the wire stripping of lower cutter 22 and cut-out action, the present invention is propping up
It is equipped with on the side plate 13 of support frame frame 10 and top board 11 whether detection upper slitter 21 is in the photoelectricity of dead-center position
Bonder, respectively first photoelectrical coupler the 41, second photoelectrical coupler 42, upper guide bracket 25 connects
Have the first brake sack 43 coordinated with the first photoelectrical coupler 41, screw mandrel 32 top connect rotate with it,
The second brake sack 44 coordinated with the second photoelectrical coupler 42, in the present invention, the second brake sack 44 is semicircle.
The present invention utilizes the first photoelectrical coupler 41 and the second photoelectrical coupler 42 jointly to detect the zero point position of upper slitter 21
Put, when the light of the first photoelectrical coupler 41 and the injection of the second photoelectrical coupler 42 is respectively by the first brake sack 43
Blocking with the second brake sack 44, it is believed that upper slitter 21 is in dead-center position, motor 31 starts, upper guide bracket 26
Driving upper slitter 21 to move downward, now, the first brake sack 43 no longer blocks the first photoelectrical coupler 41, and
Be semicircle because of the second brake sack 44 again, continue to block the second photoelectrical coupler 42, now, upper slitter 21 with
Lower cutter 22, in hemisection state, carries out wire stripping to electric wire；When the second photoelectrical coupler crossed by the second brake sack 44
42, no longer block the second photoelectrical coupler 42, then motor 31 inverts, and makes upper slitter 21 reset to lower cutter 22
Zero point, control system detects zero point, controls motor 31 and rotates forward to upper slitter 21 and lower cutter 22 and entirely cut state,
Being cut off by electric wire, so, complete the action of wire stripping and cut-out, motor 31 inverts again, continues detection zero point,
Repeat said process.
Certainly, the second brake sack 44 is not only limited to semicircle, and the present invention is to utilize the second brake sack 44
Block the second photoelectrical coupler during this period of time, make upper slitter 21 and lower cutter 22 in hemisection state.To difference
When the electric wire of thickness carries out wire stripping, only need to control the number of turns that motor 31 rotates, thus adjust upper slitter 21 with under
Cutter 22 distance between two edges of a knife when hemisection state.
In order to make the second brake sack 44 rotate with screw mandrel 32, the second brake sack 44 is connected to by the present invention to be had
On the shading seat 45 of axis hole, by coaxially connected with drive pulley 36 for shading seat 45, so, the second brake sack
44 can rotate with screw mandrel 32.
During work, electric wire is sent between the upper slitter 21 of the present invention and lower cutter 22 through the conveying mechanism of wire stripper,
When detecting that upper slitter 21 is in dead-center position, motor 31 starts, and i.e. will extend over second at the second brake sack 44
During photoelectrical coupler 42, upper slitter 21 and lower cutter 22 complete the wire stripping action to electric wire；With rear motor 31
Reversion, upper slitter 21 resets with lower cutter 22, meanwhile, strips after the electric wire of line carried with certain length,
Upper slitter 21 is in again dead-center position, and motor 31 rotates forward, and makes upper slitter 21 complete to cut electric wire with lower cutter 22
Disconnected action.Visible, the wire stripping of the present invention and cut-out action only need to be controlled to complete by a motor, compare
Traditional multiple cylinders push mode respectively, reduce cost and simple in construction；It addition, to different thicknesses
Electric wire when carrying out wire stripping, by the control to motor, i.e. adjustable upper slitter and lower cutter is when hemisection state two
Distance between the edge of a knife, degree of regulation is high, thus is greatly improved working (machining) efficiency.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that
For those skilled in the art, on the premise of without departing from the technology of the present invention principle, also
Can make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
