Description

Universal coodinate marking ruler

The utility model relates to the ruler field with adjustable cursor, particularly coordinate marking-out rule.

In machining, particularly worker, mould pincers worker complex procedures in scratching process usually scratch workpiece when drawing a design the hole.At present also do not have on the part of various complicated shapes, directly to get the coordinatometer in the required various excellent holes of drawing.

The purpose of this utility model is: provide a kind of simplification to be machined in complicated procedures of forming in the scratching process, can directly get the coordinate marking-out rule in the required various samples hole of drawing on the part of complicated shape.

The purpose of this utility model reaches like this: a kind of omnipotent coordinate marking-out rule is provided, this chi is by magnetic switch, reference base, the ordinate chi of ordinate chi and band puncher is formed, said abscissa chi, the one end is positioned on the reference base by dog screw and can be around this screw Rotate 180 °, said ordinate chi, the one end is positioned on the abscissa slide block by dog screw, and can be around this screw Rotate 180 °, said ordinate chi, the one end is positioned on the abscissa slide block by dog screw, and can be around this screw Rotate 180 °, said puncher, its lower end is fixed on the ordinate central slider, and by the hole fuse of drawing a design, sleeve and spring are formed.By magnetic switch reference base is fixed on the workpiece, by the slip and the rotation of abscissa chi and ordinate chi, when finding the position in the hole of need drawing a design, spur the handle of the device of drawing a design, can on workpiece, beat sample outlet hole, thereby the purpose of this utility model has just reached fully.

Below in conjunction with accompanying drawing the utility model is elaborated.

Accompanying drawing 1 is the schematic diagram of this coordinate marking-out rule.

Accompanying drawing 2 is the A-A sectional views of device of drawing a design on accompanying drawing 1.

Accompanying drawing 3 is left views of accompanying drawing 2 upper bushes.

From accompanying drawing 1 as seen, this coordinate marking-out rule is made up of the ordinate chi 6 of magnetic switch 1, reference base 2, abscissa chi 3 and band puncher 8.Said abscissa chi 3, the one end is positioned on the reference base 2 by dog screw 4, and can be around this screw Rotate 180 °, said ordinate chi 6, the one end is positioned on the abscissa slide block 5 by dog screw 9, and can be around this screw Rotate 180 °, said puncher 8, its lower end is fixed on the ordinate central slider 7, is made up of the hole fuse 81 of drawing a design, sleeve 82 and spring 85.

Be provided with magnet arrangement (not drawing among the figure) in magnetic switch 1 inside, magnet has magnetic force when power supply is opened, by magnetic force reference base 2 is adsorbed on the appropriate location of workpiece one side, loosening dog screw 4, abscissa chi 3 can rotate 0～180 ° in the lower end of reference base 2, after finding proper angle, dog screw 4 can be tightened, make the fixed-site of this abscissa chi 3.The dog screw 10 of pine abscissa slide block 5 on ordinate chi 6 makes ordinate chi 6 slide along abscissa chi 3 then, slides into the appropriate location, and this dog screw 10 is tightened, and abscissa slide block 5 is fixed on the abscissa chi 3.According to the position in the required hole of drawing a design, earlier loosening dog screw 9 makes ordinate chi 6 turn around this screw rotation, when rotating to suitable angle, this dog screw 9 is tightened, and ordinate chi 6 is fixed on the abscissa slide block 5 again.When arriving required sample hole site, first stationary positioned screw 12 is again with puncher 8 hole of drawing a design.

Structure from accompanying drawing 2 visible punchers, accompanying drawing 2 is sectional views of accompanying drawing 1A-A, at ordinate chi 6 middle parts one neutral gear 11 is arranged, ordinate central slider 7 helps in the groove that is inserted in neutral gear 11 both sides with two of protrusion and slides, the lower end of the sleeve 82 of puncher 8 is fixed on circular hole in the slide block 7 on week, therefore, coordinate central slider 7 can drive puncher 8 along 6 slips of ordinate chi.Said puncher 8 is made up of the hole fuse 81 of drawing a design, sleeve 82 and spring 85.Hole fuse 81 lower ends of drawing a design are tapered.Tip is a tip, this tip squeeze into surface of the work the hole of drawing a design.The tapered portion upper end is thinner bar portion, and bar portion is with handle 84 topmost, is provided with the outside driving lever of pitching out 86 on tapering point top and bar subordinate end, and this driving lever is outside sleeve pod 821 stretches out sleeve 82.Said sleeve 82 is cylindrical shapes, the hole fuse 81 of will drawing a design wraps in the inside, a pod 821 is arranged in the middle of this sleeve, can see clearly from accompanying drawing 3, accompanying drawing 3 is sleeve left views of the puncher of accompanying drawing 2, is provided with a hyphen ditch 822 in this pod one side, be provided with receiver 83 in this upper cartridge, it fastens sleeve 82 ends and spring 85, and the bar portion of the hole fuse 81 of drawing a design passes from these receiver 83 middle parts, between the bar portion of sleeve 82 inside and the hole fuse 81 of drawing a design the spring 85 that is enclosed within this bar portion is arranged.

When finding the position in the hole of drawing a design, with hold-down screw 12 slide block 7 is fixed, make the pod 821 of driving lever 86 alignment sleeve 82, mention handle 84 with finger, the whole hole fuse 81 of drawing a design is upwards carried, and driving lever 86 also upwards slides along pod 821, at this moment, the spring 85 of the inside is compressed, aim at the hole of being found of drawing a design then, the hole fuse 81 of will drawing a design is suddenly put back to, and fuse is borrowed the elastic force of spring 85, make its tip beat the hole site of drawing a design, can get the hole of drawing a design at surface of the work and come at workpiece.At ordinary times, the tip of fuse is exposed, can driving lever 86 upwards be slided portable handle along pod 821, rotating fuse then is screwed into driving lever 86 in the hyphen ditch 822, fuse 81 tips are in the slide block 7, and turn fuse again during use is got back in the pod 821 driving lever 86.

After finishing using, ordinate chi 6 and abscissa chi 3 can be rotated on the same direction, spin off puncher 8 again, close magnetic switch, the chi box of packing into together.

The omnipotent coordinate marking-out rule of the utility model utilizes the principle of coordinate anyhow and the angular adjustment of chi anyhow, to the workpiece hole of drawing a design, can simplify machining, particularly worker, the complicated procedures of forming of mould pincers worker in scratching process; Can on various complicated parts, directly get the required various samples hole of drawing; Can protect workpiece not to be scratched; Line efficient height; Precision is also high.This marking-out rule is simple in structure, easy to use and manufacturing.
