Abstract

The utility model discloses a quick graduation scribing instrument of ring flange, its structure is equipped with a supporting screw for radially following at a fixed graduated disk outward, and bottom central point puts and is equipped with a supporting screw, and an activity graduated disk is equipped with on upper portion, is equipped with a scriber pole that has the scale on the activity graduated disk, is equipped with a slidable and can fix a position the scriber on the scriber pole. The scribing instrument has the advantages of simple structure, portability and convenient use, and is suitable for indexing and scribing the flange plates of various specifications.

Description

Quick scriber for flange plate graduation

The utility model belongs to draws the figure instrument field, is specifically related to a kind of ring flange diagraph.

The calibration of ring flange line at present all adopts traditional camber line to cut the footpath function scribble method and the clumsy traditional-handwork technique of painting.Chinese patent 86204124 discloses a kind of multi-functional lining instrument, its objective is that solution can mark the arbitrarily angled intersection when crossing of any geometrical body and pipe directly and accurately on the body surface, on plane, interior positive camber, male and fomale(M﹠F), mark the problem of various curves such as arbitrarily angled, round, oval, circumference Along ent position.Its major technique feature is to be provided with 360 ° of dial discs and angle vernier on magnetic bases, on dial disc, be equipped with can 180 ° radially movable montants, the montant arm pull cover that can move up and down is housed on the montant, montant is drawn wall and is put arm pull and scriber are housed, on montant, also be equipped with along the montant axis and not only can have slided up and down but also rotating montant disk, be provided with 90 ° of dials and cross bar on the montant disk, cross bar is provided with cross bar arm pull cover and scriber.The weak point of this invention is because function is more, thus the structure more complicated, and manufacture process requirement is higher.

The utility model purpose provides a kind of simple in structure, portable ring flange quick index lining instrument.

The technical scheme that realizes this purpose is in the radially outer of the fixed indexing plate with 360 ° of scales at least one support bar to be housed, the centering folder of a tightening position is housed on every support bar at least, bottom centre position in fixed indexing plate is equipped with an adjustable studdle, movable index dial with subscale mark is housed on the top of fixed indexing plate, in the radially outer of movable index dial a scriber bar that has rule is housed, the scriber that slidably also can locate is housed on the scriber bar.

The advantage of this lining instrument is centering and a calibration problem small and exquisite, portable, that the simple way fast of usefulness has solved ring flange, and its precision height is applied widely.

The utility model has following accompanying drawing:

Fig. 1 diagraph duty front view;

Fig. 2 diagraph duty vertical view;

Fig. 3 double end scriber working state schematic representation;

Fig. 4 double end scriber structural representation;

Fig. 5 folder working state schematic representation of feeling relieved.

Embodiment:

On fixed indexing plate 1, demarcate 360 ° of scales are arranged, radially be provided with three grooves in fixed indexing plate, inserting a support bar 4 backs in each groove compresses it with volution, on every support bar 4, be provided with the centering folder 6 of a tightening position, centering folder 6 is eccentric wheel apparatus, centering folder 6 can move on support bar 4, and is by tightening switch 12 that support bar 4 is fixing with workpiece ring flange 8.Bottom centre position in fixed indexing plate 1 is equipped with an adjustable studdle 7, regulates the height of studdle when its effect is to use so that lining instrument support bar 4 is contour with ring flange.On the top of fixed indexing plate 1 a movable index dial 2 with 360 ° of subscale marks is housed, has adopted the sliding connection of axle between them with cover.Adopt thread connecting mode that a scriber bar 3 that has millimeter rule is housed in the radially outer of movable index dial 2, the scriber 5 that slidably also can locate is housed on scriber bar 3, its installation method can be, on scriber 5, establish a hole, be provided with screw thread in the hole and be equipped with a holding screw, scriber 5 is enclosed within on the scriber bar 3 and can slides, and is transferred to the appropriate location, screws to mark closely screw and can fix.

This lining instrument divides large, medium and small three kinds of specifications to be applicable to that respectively diameter is 1500～2500 millimeters, the calibration of 750～1500 millimeters and 70～750 millimeters ring flanges, line.In calibration, line during 70～750 millimeters ring flanges, scriber can be with common single head scriber.But when on big ring flange, ruling, because the workpiece span is big, three support bars thicker (about 10 millimeters), so with scriber chamfering bit aperture line the time, scriber head three support bars that can't overturn.Therefore, 180 ° of commutations have fast been disposed, the double end scriber of upset support bar.Its duty as shown in Figure 3.Its structure will have on the scriber body 10 of the scriber body 9 cover forward (FWD) springs of locating slot and steel ball as shown in Figure 4, fix with the screw thread on nut and the scriber body 10 again, and still, requirement assurance scriber body 9 can rotate and not have too big gap.Semicircle locating slot on the scriber body 9 plays the role of positioning by spring and steel ball.

Each parts of this lining instrument can be dismantled the dress box and be easy to carry, and are easy to install.This lining instrument can also be used for the calibration line work of plumber's unfolding and cutting.

Claims

1, a kind of ring flange quick index lining instrument, comprise fixed indexing plate 1 and scriber 5 with 360 ° of scales, it is characterized in that at least one support bar 4 being housed in the radially outer of fixed indexing plate 1, at least be contained in the centering folder 6 of a tightening position on every support bar 4, bottom centre position in fixed indexing plate 1 is equipped with an adjustable studdle 7, movable index dial 2 with subscale mark is housed on the top of fixed indexing plate 1, movable index dial 2 with subscale mark is housed in the radially outer of movable index dial 2, the scriber bar 3 of a band rule is housed in the radially outer of movable index dial 2, the scriber 5 that slidably also can locate is housed on scriber bar 3.

2, ring flange quick index lining instrument as claimed in claim 1, it is characterized in that described scriber 5 can be 180 ° of commutations fast, the double end scriber of upset support bar, its structure is to overlap on the scriber body 10 of forward (FWD) springs and steel ball with the scriber body 9 of locating slot, fixes with the screw thread on nut and the scriber body 10 again.
