Abstract

The utility model relates to a passive self-rotating burin device which is controlled by a computer and is used for a drawing machine. The burin adopts a cylindrical knife body, and a cutting edge passes the center line of a knife bar. A knifepoint is crossing point of three faces and deviates from the center line of the knife bar. When the utility model is used to cut adhesive advertisement words or special-shaped adhesive labels and paper pattern of clothes with various different specifications, the depth which is created by cutting into an object can be precontrolled by a pressure adjustment button. The knifepoint of the burin can automatically rotate and track along the tangential direction of curves in the operation track of the utility model. So the purpose of the completion of cutting curves and cutting a circular arc can be achieved. The carved patterns are relatively accurate.

Description

Passive self-rotating burin device

The utility model belongs to machine cutter device, particularly is applied to the passive type spinning icking tool on the computer-controlled draught machine.

Generally the use a computer draught machine of control, only to draw different curve and pattern with pen on drawing, not seeing as yet in computer-controlled draught machine and in the interrelated data at present writes on one's behalf with cutter scribes the device of curve or figure.This is because blade is that face is formed, and nib is for a bit, as if on the position that icking tool is loaded on draught machine clamping pen the time, when scribing curve, will inevitably make by quarter paper go out burr or tear.

The purpose of this utility model just provides a kind of by the passive type spinning icking tool device that uses on the computer-directed drawing machine, blade can be advanced with the curve tangential direction automatically.

Figure one is a passive type spinning icking tool structural representation, among the figure: 1 overcoat, covers, 3 adjusting levers, 4 cushion rubbers in 2,5 pressure are adjusted button, 6 springs, 7 ring washers, 8 springs, 9 bearings, 10 broach shells, 11 knife bars, 12 grades of ring first, 13 and grade are encircled second, 14 points of a knife, 15 end faces.

Figure two is the bottom view of this device, among the figure: 16 blades

The following formation of structure of the present utility model: knife bar 11 is a cylinder, blade is by the cylinder center line, point of a knife departs from the knife bar center line, point of a knife is the intersection point of three faces, and the upper end of knife bar is cone-shaped, and knife bar inserts in the broach shell 10, the interior cover that is clamping ring washer 7, broach shell and bearing 9 in the cone-shaped bottom on bar top is fixed, spring 8 is loaded between ring washer 7 and the bearing 9, supports ring washer by spring 8 knife bar 11 is held up the center of withstanding adjusting lever 3 bottom end faces.Interior cover 2 is installed in the outer of bearing 9 and puts, overcoat 1 can slide relatively with interior cover 2, there is adjusting lever 3 backing upper end at interior cover by spiral marking connection, button 5 is adjusted with threaded connection pressure in the top of overcoat 1, the adjusting lever upper end passes the endoporus that pressure is adjusted button 5, spring 6 is installed in pressure and adjusts between the upper surface of button 5 and interior cover, and baffle ring first 12 is used spiral marking connection with overcoat and interior cover 2 respectively with baffle ring second 13.

Below accompanying drawing is explained, the draught machine clamping that overcoat among the figure one is controlled by computer, when scribing special-shaped adhesive sticker pattern, the rotation adjusting lever can reach point of a knife and end face 15 to want the degree of depth that reaches by knife bar, end face 15 is close to processed self-adhesive paper point of a knife and is moved in company with plotter that computer program is controlled during work, because point of a knife departs from the knife bar center, when knife bar when curvilinear path is moved, point of a knife is dragged then by this device and moves from motion tracking along its tangential direction.Can make groove at the thread segment middle part of adjusting lever 3, cushion rubber is housed in the groove, prevent that adjusting lever is loosening.Blade 16 among the figure two is by the center line of knife bar, and point of a knife 14 is the center line that the intersection point of three faces departs from knife bar.

The utility model can in time make point of a knife turn to when scribing the corner of figure, and institute's needle drawing shape is more accurate.Made figure is mainly used in that block in the plate-making not need exposure place, can also scribe each and decorate with figure, pattern etc.

Claims

1, a kind of passive type spin icking tool device, it is characterized in that knife bar 11 is cylinder, blade is by cylindrical center line, point of a knife departs from the knife bar center line, point of a knife is the intersection point of three faces, the upper end of knife bar is cone-shaped, and knife bar inserts in the broach shell 10, and knife bar top is clamping back-up ring 7, the interior cover of broach shell and bearing 9 is fixed, spring 8 is loaded between back-up ring and the bearing, and interior cover 2 is installed in the outer of bearing 9 and puts, and overcoat 1 can slide relatively with interior cover 2, thread connection adjusting lever 3 is passed through in inwall upper end at interior cover, the adjusting lever bottom end face withstands the knife bar upper end, and button 5 is adjusted with the pressure that is threaded in the top of overcoat, and the adjusting lever upper end passes the endoporus that pressure is adjusted button 5.

2, by the described passive type spin of claim 1 icking tool device, it is characterized in that the thread segment middle part of adjusting lever 3 is fluted, cushion rubber 4 is housed in the groove.
