Abstract

The utility model relates to a marking positioning device, in particular to a high-precision marking positioning device, which comprises a straight rule and a positioning pin; wherein the rule plate of the straight rule is provided with scales, and through grooves are opened every equal or unequal scales on the rule plate. The high-precision marking positioning device has the advantage of simple structure that the rule plate of the straight rule are provided with opened through grooves; the through grooves and their corresponding and mating marking pins are used together; After the hole spacing for punching is determined, the through grooves are used for pointing to the position on the straight line; the marking pins are inserted into the through grooves to mark and form cross lines, thus greatly reducing the error; besides, the cross positioning pins are cooperated; the cross positioning grooves of the casing end is used for positioning, overlapping with the cross lines formed by marking before; the center of the positioning pins in the casing is positioned in the intersection point of the cross lines, directly pinching out of the positioning holes and further improving the precision; proved by experiments, the marking positioning device greatly reduces the use cost with a punching precision up to a boring machine level and an error controlled between two to three lines.

Description

High accuracy line positioner

Technical field:

The utility model relates to the line positioner.

Background technology:

At present industrial when the line of hard materials such as iron plate or steel plate, punching, particularly with the hard plate material of existing fixed hole position assembling, precision prescribed is high especially, adopt boring machine can improve precision, precision is controlled in the 2-3 road error range, but boring machine manufacturing cost, use cost are all too high, when adopting line of simple tools chi or punching, need artificial earlier line location, equipment cost reduces, but the manually-operated error is big, sheet material is long more, and line and locating hole quantity are many more, and density is big more, error is big more, is difficult to guarantee the quality of product.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of high accuracy line positioner is provided, and simple and reasonable, cost is low, and is easy to use, the precision height.

The technical scheme that the utility model is adopted for achieving the above object is: high accuracy line positioner, comprise marking-out rule and pilot pin, and have scale on the marking-out rule chi plate, interval equalization or non-uniform scale have groove on the chi plate.

The saturating groove of described marking-out rule is opened in chi plate one side, both sides or centre.

Described marking-out rule is dip sticks such as ruler, set square or protractor.

Described pilot pin is to be set with pilot pin in the locating sleeve, and the pilot pin afterbody grows sleeve pipe, and the sleeve end headband has the cross locating slot.

Described pilot pin sleeve pipe termination has undercut.

The utility model is simple in structure, have groove on the marking-out rule chi plate, saturating groove and the corresponding supporting use of scriber, determine to treat behind the punching spacing distance saturating groove aimed at that straight line is upper to be put, scriber inserts line formation cross hairs in the groove, reduce error greatly, cooperate the cross pilot pin in addition again, cross locating slot location by the sleeve pipe termination, the cross hairs that forms with line before overlaps, and the pilot pin in the sleeve pipe is centered close to the venter of relicle position, directly goes out locating hole, further improve precision, the experiment proved that the utility model not only greatly reduces the production cost of equipment, and use cost reduces greatly, the punching precision can reach the precision of boring machine, and departure is between the 2-3 road.

The specific embodiment:

Embodiment 1

High accuracy line positioner, comprise the supporting use of the pilot pin shown in marking-out rule shown in Figure 1 and Fig. 3,4, have scale 2 on the marking-out rule chi plate 1 on one side, have a saturating groove 3 every the 10mm scale on the another side, saturating well width is 2mm, the centre position is positioned on the scale, and the scriber diameter supporting with it is that 2mm subtracts 2 roads.After adopting marking-out rule to draw line, the pilot pin of supporting use shown in Fig. 3,4, pilot pin are to be set with pilot pin 5 in the locating sleeve 4, and the pilot pin afterbody grows sleeve pipe, and the sleeve end headband has cross locating slot 7, and the pilot pin termination also has annular undercut 6.

Embodiment 2

High accuracy line positioner, comprise the supporting use of the pilot pin shown in marking-out rule shown in Figure 2 and Fig. 3,4, both sides all have scale 2 on the marking-out rule chi plate 1, (can equalization or non-uniform scale on the chi plate every the 5mm scale, customize according to actual needs) have a saturating groove 3, saturating well width is 2mm, and the centre position is positioned on the scale, and the scriber diameter supporting with it is that 2mm subtracts 2 roads; Pilot pin is identical with embodiment 1.
