A kind of two-freedom automatic cutting device and using method
Technical field
The present invention relates to the device of surface trimming adhesive tape in a kind of wire harness wrapping industry, particularly a kind of two-freedom is certainly
Dynamic cutter sweep and using method.
Background technology
Machining is the main method of mechanical manufacturing field.It uses cutting element material unnecessary on blank or workpiece
Layer cuts, and makes the processing method that workpiece obtains the geometry, size and the surface quality that specify.Cutting element is referred to as cutter.
Cutter extension set bed is used, hands is used.In machine-building, cutter can be used in the various material such as cutting metal, macromolecule.Cut
Cut processing at lathe, Making mold, automobile and parts manufacture, universal machine manufacture, shipbuilding, Aero-Space, wind-powered electricity generation, rail
Multiple terminal applies industries such as road traffic, electronic apparatus, five metals and nonmetallic materials manufacture have a wide range of applications.
Cutting off tool is the cutter that a class is special, including: tooth blade, band saw, bow saw, parting-off tool, metal saw, hands
The multiple subclasses such as work instrument.The cutting edge protection of a lot of parting tools is bad, the most easily incised wound limbs of user, non-processing
Object;On the other hand the most easily allow work cutting edge directly bump to hard thing, damage cutting edge.
At present, on market, existing wire harness rubber coating machine is rubber coating machine small-sized, semi-automatic, when the task of completing the encapsulated band of wire harness
After, need manually to be cut off by adhesive tape by the blade on small-sized rubber coating machine, thus carry out next step encapsulated operation.But for entirely
The encapsulated platform of wire harness automatically, it is necessary to a kind of adhesive tape automatic disconnecting device, and this device practicality will be extensively, for difference
Width, the adhesive tape of material be intended to preferably cut off effect.
Summary of the invention
In order to realize automatically cutting off the function of adhesive tape on the encapsulated platform of full-automatic wire harness, the present invention provides a kind of two freely
Degree automatic cutting device and using method, this device can cut off the material adhesive tapes such as PVC, thin fabricbase, thick fabricbase, felt, velvet,

Described blade cover is notched circle, it is ensured that blade will not accidentally injure people or the thing of surrounding;
Described blade is the special-shaped blade of n-shaped, and shown N is 3-12.
A kind of using method of two-freedom automatic cutting device, specific as follows:
When there being oscillating cylinder to drive signal, the output shaft of oscillating cylinder is connected with L-type support sidewall relative motion;Swing
Cylinder drives swing arm to swing by its rotating shaft, and oscillating cylinder swings certain angle, thus drives swing arm to swing, and then drives whole
Individual knife rest swings;Complete cutting action;Knife rest is fixed in swing arm, swings with swing arm;
Change speed gear box, blade cover and motor are fixed on knife rest, and machine shaft is connected with the driving gear in change speed gear box, when having
During motor drive signal, motor rotates, and drives driving gear to rotate by the rotation of motor shaft, belt connect driving gear and from
Moving gear, makes driving gear drive driven gear to rotate, and blade is fixed on change speed gear box driven gear, and driven gear rotates, band
Cutting blade rotates.
The invention has the beneficial effects as follows:
Notched circular shear blade cover, it is ensured that blade will not accidentally injure people or the thing of surrounding, will not damage wire harness, not interfere bag
Glue effect;Change speed gear box can change the rotary speed of blade, makes blade work in rational rotating speed;The support of L-type decreases
Installation dimension;Electric machine rotational axis is misaligned with blade rotary shaft, is conducive to alleviating the load of knife rest cantilever beam;Abnormity blade is permissible
Produce sawing effect, full-automatic wire harness rubber coating machine achieve automatically cutting off of adhesive tape, and be adapted to PVC, thin fabricbase,
The adhesive tape of the unlike materials such as thick fabricbase, felt, velvet, will not cause adhesive tape to glue mutually, draw white, longitudinal tear in cutting-off process
Etc. phenomenon.
