Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In description of the present utility model, it will be appreciated that, orientation or the position relationship of the instruction such as term " vertically ", " level ", " top ", " end ", " interior ", " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See Fig. 1 to Fig. 4, sheet material hand circle-cutting cutter sweep, cutting aid and cutting element.The pressure pin 20 that described cutting aid comprises bracing or strutting arrangement 10 and is arranged on above bracing or strutting arrangement 10; One end of pressure pin 20 can horizontally rotate with the top of bracing or strutting arrangement 10 and is connected; Pressure pin 20 is provided with the locking member 22 of cutting element installed part 21 and locking cutting element installed part 21; Described cutting element comprises drive unit, and when cutting car 40 uses, cutting car can away from cut sheet material and the cutting air gun 41 be connected with cutting car 40; Cutting air gun 41 is fixed on pressure pin 20 by cutting element installed part 21; Described drive unit horizontally rotates for driving pressure pin 20.
Cutting air gun 41 is arranged on cutting element installed part 30, locked by locking member 22 again, prevent locking cutting element installed part 21 from moving relative to pressure pin 20, then pressure pin 20 is driven to rotate by drive unit, pressure pin 20 axle centered by the vertical axis of itself and bracing or strutting arrangement 10 junction rotates, thus realize the circle of contact on sheet material, the center of circle of the circle material that cutting is lower and the junction of pressure pin 20 and bracing or strutting arrangement 10, radius is the distance of pressure pin 20 being installed by itself and bracing or strutting arrangement 10 junction to pressure pin 20 between cutting element installed part 30.
Described drive unit is any structure being convenient to drive pressure pin 20 to rotate in prior art, and can be such as motor etc., drive unit belong to inventive point of the present utility model, does not describe in detail at this.
Described bracing or strutting arrangement 10 is A-frame structure.Bracing or strutting arrangement 10 can adopt column structure, supporting structures etc. are convenient to the structure supporting pressure pin 20 and be arranged on the cutter sweep on pressure pin, preferred employing A-frame structure, because triangle is stable structure the most, therefore A-frame structure is adopted to carry out supporting more stable, the more important thing is, not easily there is deflection or displacement in bracing or strutting arrangement in whole cutting process, thus reduce the error of circular material as much as possible.
Described cutting element installed part 21 with along pressure pin 20 length direction slidably mode be arranged on pressure pin 20.Slidingtype is arranged can regulate circle of contact radius easily, expands the scope of application of this sheet material hand circle-cutting cutter sweep.
Described pressure pin 20 comprises outer bar 20a and interior bar 20b; Described outer bar 20a has opening 20c along its length; Interior bar 20b can bar 20a be interior along outer bar 20a length direction slip outside; Cutting element installed part 30 is fixedly connected on interior bar 20b, and stretches out from the opening 20c of outer bar sidewall, and cutting element installed part 30 is positioned at the outside of outer bar 20a.Because outer bar 20a has opening 20c along its length, therefore, during by twitching interior bar 20b, the opening 20c of cutting element installed part 30 on outer bar 20a sidewall is also moving, thus realize regulating cutting element installed part 30 and the object of the spacing of bracing or strutting arrangement, namely can regulate and cut radius of a circle.In addition, in interior bar 20b and outer bar 20a arranges, interior bar 20b therefore can also be avoided in cutting process as much as possible to shake the circle of contact error produced.
Described locking member 22 is tie down screw, and one end of described tie down screw through outer bar 20a sidewall, and offsets with the sidewall of interior bar 20b.Tie down screw is turned in outside bar 20a, tie down screw is made to pass the sidewall of outer bar 20a, continue again to turn tie down screw, until the side-wall outer side of the end of tie down screw and interior bar 20b offsets, continue again to turn, make tie down screw to sidewall pressure of interior bar 20b, thus limit the relative movement between interior bar 20b and outer bar 20a, and then define and be fixedly connected on the movement of the cutting element installed part 30 on interior bar 20b relative to outer bar 20a.
This locking member structure is simple, only needs outside bar 20a to wear a screwed hole, uses also very convenient, staff directly can turn tie down screw as required, and bar in then twitching, finally tightens tie down screw again, can realize the change of circle of contact radius, locking effect is also fine in addition.
During concrete enforcement, outside bar 20a and interior bar 20b can also arrange multiple screwed hole, during locking, by tie down screw successively through the screwed hole of the correspondence on outer bar 20a and interior bar 20b, thus the locking realized between outer bar 20a and interior bar 20b, this structure locking better effects if, but the change of circle of contact radius is limited, is not too flexible.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
