Description

Section bar knuckle marking-out rule

The utility model is a kind of section bar knuckle marking-out rule, is a kind of special-purpose bevel protractor of line usefulness when being used for angle steel, channel-section steel, I-steel, square steel etc. and being converted into a certain angle.

At present, to on section bar, remove the unnecessary material of a certain angle, bending then, generally finish with " universal protractor ", still " universal protractor " belongs to fine measuring instrument, costs an arm and a leg, can not accomplish one of staff, and utilize " universal protractor " to carry out the bending of section bar, and can only guarantee the requirement of angle, can not guarantee the bending quality.

The utility model proposes a kind of section bar knuckle marking-out rule, it mainly is in order to solve the problem of real work section bar knuckle line.

The utility model is a kind of section bar knuckle marking-out rule, it is characterized in that: it is made up of left comer chi, right corner chi, di-gear, station meter, support, lock shaft, trip bolt, wing nut.One end of left comer chi is a ruler, on the angle groove is arranged, the other end is an arc plate, the arc plate inner edge has internal tooth, one end of right corner chi is a ruler, the other end is with the concentric arc plate of left comer chi arc plate, there is external tooth its arc plate outside, and the internal tooth number of teeth of the number of teeth and left comer chi equates, the modulus difference, support is the support of the U type that curved by a rectangular slab, the length groove is arranged on the station meter, end at its zero graduation line has an end face perpendicular to center line, station meter is along having a slotted hole on the center line, station meter can be moved along center line, with the left comer chi, the right corner chi support of packing into, station meter is placed on above the support, by di-gear and lock shaft, wing nut makes the left comer chi, the right corner chi, the central lines of support and station meter, and di-gear and lock shaft when installing also on this center line, di-gear and left comer chi, the right corner chi is meshed, when the di-gear rotates, the angle that left comer chi and right corner chi form is divided equally by the center line of station meter, the end face of station meter contacts with profile wall, and the station meter end face is the section bar wall thickness to the distance of left comer chi and right corner chi formation angle, and station meter is controlled by trip bolt along moving of center line.

Di-gear described in the utility model is made up of left comer chi gear and right corner chi gear, wheel shaft, nut, left comer chi gear and right corner chi gear are one group of concentric gear, the number of teeth equates, modulus keeps left and right angle square gear to rotate the moving identical angle of time shift, left comer chi gear is meshed with left comer chi internal tooth, and right corner chi gear is meshed with right corner chi external tooth.

The utlity model has simple in structurely, easy to use, can draw any angle on as angle steel, I-steel, square steel, channel-section steel, this section bar knuckle marking-out rule cost is low, is convenient to grasp and use.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a profile of the present utility model.

Fig. 3 is a side view of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

By Fig. 1 and Fig. 2 as can be known, the utility model section bar knuckle marking-out rule, form by left comer chi 1, right corner chi 2, di-gear, station meter 5, support 6, lock shaft 8, trip bolt 9, wing nut 11, left comer chi 1, right corner chi 2 support 6 of packing into, station meter 5 is contained in above the support 6, make the central lines of left comer chi 1, right corner chi 2, support 6, station meter 5, di-gear and lock shaft 8 also are installed on this center line, and an end of the isocentric circular arc of left comer chi 1, right corner chi 2 is meshed with the di-gear.The angle groove is arranged on the left comer chi 1, the length groove is arranged on the station meter 5, one end face perpendicular to station meter 5 center lines is arranged at its zero graduation line one end.When measuring, section bar knuckle marking-out rule is separated into institute's palpus angle, soon the inner edge of right corner chi 2 is aimed at the angle index line on the left comer chi 1, lock shaft 8 is by wing nut 11 lockings then, keep angle constant, section bar knuckle marking-out rule is placed on the bending part of section bar, make the inwall of the summit aligning section bar of its angulation, adjust station meter 5, its end face contacted with the section bar outer wall is parallel, read and be of a size of the section bar wall thickness, screw 9 then is locked, fixed base object staff 5 is motionless, in the line of want bending part, finishes the angle line.
