Abstract

The utility model discloses an improved vernier of a coordinate setting angle square belonging to the technical field of measuring implements. The zero position ends of two rulers marked with scales are in butt joint to form a coordinatometer; a longitudinal coordinatometer and a horizontal coordinatometer are respectively provided with a vernier which is a non-scale surrounding vernier; one surface of a snap gauge of the vernier is a plane, the middle of the other surface is provided with a groove having the thickness and width adaptive to the coordinatometer, one side of the snap gauge is provided with a knob locking top thread, the groove of the snap gauge is clamped on the bottom of the coordinatometer and is mutually locked with a panel chamfered with an inclined plane by screws, and a chamfer end faces to the zero position end of the coordinatometer. The utility model can bring convenience for operating personnel requiring manual drawing and for operating personnel in the hardware processing industry to great extent and improve working efficiency.

Description

A kind of vernier scale of improved coordinate setting angle square

Technical field

The utility model belongs to the measurer technical field, relates to a kind of vernier scale of coordinate setting angle square.

Background technology

Up to now, continue to use always when hand-drawing and machining people be that the intersection point that ruler or angle square are measured ordinate and abscissa is located by the point sampling method on object plane, and the obtained biased difference of point of this method is bigger, and this is well-known in the industry; So giving needs the people of hand-drawing and five metals processing to bring very big inconvenience and helpless.In order to address this problem, I have invented a kind of coordinate setting angle square specially through for many years practice summary, bring work convenient and increase work efficiency can for largely the people that need hand-drawing and five metals processing industry.The patent application " a kind of coordinate setting angle square " (application number 2010102081274) of my proposition before this, find through sampling, because of the vernier scale on the slide calliper rule of the vernier scale in the former invention and prior art exists very big different in the use, so, need not imitate fully, and, can derive fully and be more suitable for former invention characteristic and simple and practical vernier scale.

Summary of the invention

The purpose of this utility model is to provide a kind of vernier scale that the coordinate setting angle square that makes improvements is arranged, with its pointed structural design provide a new solution for improving above-mentioned existing problem, thereby help improving the practicality and the progressive of product.

For achieving the above object, solution of the present utility model is:

A kind of vernier scale of improved coordinate setting angle square, by the zero-bit end of two rulers that indicate scale to being connected into coordinatometer, getting the crossing common point of ordinate chi and abscissa chi zero-bit is anchor point, with this anchor point is that a trepanning is opened at the center, and on this trepanning, dispose a sleeve that supplies marking pen to use, on ordinate chi and abscissa chi, vernier scale is installed respectively; Described vernier scale is no scale encircling type vernier scale, be made up of clamp, panel, knob jackscrew and installation screw: 1, the one side of clamp is the plane, another side is that the middle part has with the width of coordinatometer and thickness adapts and slidable groove, and have at this face and screw to be installed and to have the screw that the knob jackscrew is installed in a side of clamp, the groove of clamp is stuck in the bottom surface of coordinatometer; 2, the plate face area of panel is identical with clamp plate face, one side is the plane, one chamfer of another side becomes the inclined-plane, have on the plane of chamfering not with clamp on the corresponding installing hole of screw hole is installed, the fillet surface of panel is positive, chamfered end is towards the zero-bit end of coordinatometer, and between the clamp with screw being installed to lock, and make whole vernier scale after the installation can be on coordinatometer smooth and easy sliding; 3, the knob jackscrew is installed on the reservation screw of clamp one side.

After adopting such scheme, the utlity model has and process advantages such as simple, easy to use.

The specific embodiment

Please refer to Fig. 1, Fig. 2, Fig. 3:

With the zero-bit end butt joint of ordinate chi 2 and abscissa chi 1, getting its common point that intersects is anchor point, is that a trepanning is opened at the center with this anchor point, and disposes an abutment sleeve 5 that supplies marking pen to use on this trepanning.

Described vernier scale 3 is no scale encircling type vernier scale, and it is made up of clamp 3.1, panel 3.2, knob jackscrew 3.5 and installation screw 3.3:

1, the one side of clamp 3.1 is the plane, open at the middle part of another side one be slightly larger than the width of coordinatometer and the groove 3.6 of thickness, and open at this face screw hole 3.4 be installed, and open a screw that knob jackscrew 3.5 is installed in a side of clamp 3.1; The groove 3.6 of clamp 3.1 is stuck in the bottom surface of coordinatometer.

2, the plate face area of panel 3.2 is identical with clamp 3.1 plate faces, one side is the plane, one chamfer of another side becomes the inclined-plane, open on the plane of chamfering not with clamp 3.1 on the corresponding installing hole of screw hole 3.4 is installed, the fillet surface of panel 3.2 is positive, chamfered end is towards the zero-bit end of coordinatometer, and between the clamp 3.1 with 3.4 pairs of locks of screw are installed, and make whole vernier scale 3 after the installation can be on coordinatometer smooth and easy sliding.

3, knob jackscrew 3.5 is installed on the reservation screw of clamp 3.1 1 sides.

Vernier scale 4 is identical with vernier scale 3.

Claims

1. the vernier scale of an improved coordinate setting angle square, by the zero-bit end of two rulers that indicate scale to being connected into coordinatometer, getting the crossing common point of ordinate chi and abscissa chi zero-bit is anchor point, with this anchor point is that a trepanning is opened at the center, and the sleeve that a confession of configuration marking pen is used on this trepanning, on ordinate chi and abscissa chi, vernier scale is installed respectively, it is characterized in that: described vernier scale is no scale encircling type vernier scale, by clamp, panel, knob jackscrew and installation screw are formed: the one side of its clamp is the plane, the middle part of another side has the groove that width and thickness with coordinatometer adapt, and on this face, open the installation screw, and open a screw that the knob jackscrew is installed in a side of clamp, the groove of clamp is stuck in the bottom surface of coordinatometer; The plate face area of its panel is identical with clamp plate face, one side is the plane, one chamfer of another side becomes the inclined-plane, open on the plane of chamfering not with clamp on the corresponding installing hole of screw hole is installed, the fillet surface of panel is positive, chamfered end is towards the zero-bit end of coordinatometer, and between the clamp with screw to lock; The knob jackscrew is installed on the screw of clamp one side.
