Abstract

The utility model relates to an angle gage for a pipe, which is a measuring instrument used for measuring the bent angle and tangential point position of a pipe. The angle gage of the utility model is composed of an angle dial plate (6) and a left and a right angle squares a, b which can rotate around a shaft. The left angle square a is fixed on the dial plate (6), and the right angle square b can rotate around the shaft to carry out the angle measurement. The left angle square a has a vernier measuring tool which can measure any length of the bending inner radiuses of pipes within certain limit, and the angle measuring gage can measure the bent angles and the tangential points of pipes in different pipe diameters and different bending radiuses.

Description

The pipe bevel protractor is a kind of measurement instrument.
At present, the angle of bend of measurement pipe is with setting-out, model and fixed bevel protractor.By 78 years~84 years data such as " measurement digests " are retrieved, do not find the use and the interrelated data of this utility model.
The purpose of this utility model is:
1, measures the angle of bend and the position, point of contact of pipe with the absolute magnitude method.
2, measure pipe inside radius of the bend arbitrary numerical value within the specific limits with vernier measuring tool, accomplish universalization.
The structure of this bevel protractor as shown in Figure 1.It by index dial (6), be fixed on left comer chi a on the index dial, can form around right corner chi b, axle (13), spiral shell fourth (14) and wing nut (15) that axle (13) rotates.Angle square a, b be respectively by slideway (9), (11), groove (10), (12), and gusset (3), (7), hand-screw spiral shell fourth (1), spring leaf (2), spiral shell fourth (8), bolt (4) and vernier (5) are formed.
As shown in Figure 1, this bevel protractor has one to be the fan-shaped angle dial (6) in the center of circle with axle (13).On index dial, angle square a, b have respectively can be around slideway (9), (11) that axle (13) rotates.Having respectively on slideway (9), (11) can be along groove (10), (12) that slideway slides.Have the surface to be carved with the gusset of length value (3), (7) on groove (10), (12) respectively, vernier (5) is arranged on groove (10), they are fixed on groove (10), (12) by spiral shell fourth (8).Hand-screw spiral shell fourth (1) and spring leaf (2) can be fixed on groove the arbitrary position on the slideway, play the effect of regulating pipe inside radius of the bend length by vernier (5).Left side slideway (9) is fixed on the index dial (6) with bolt (4), and the side of assurance angle square a is on index dial zero degree line position.Wing nut (15) is gone up the M8 external thread with axle (13) and is connected, and is used for fixing axle (13) and angle square location.The base of two angle squares is vertical with side.The center of circle of axle (13) is the intersection point of angle square a, b dual-side extended line.Expression tube bending inside radius length R is arranged on slideway (9) nGroove, unit is 1mm.Vernier indicating value above the vernier (5) is 0.05mm.The length of right corner chi b is benchmark with left comer chi a.
The angular error of this bevel protractor is ± 5 ', error in length is 0.05mm, the measurement of angle scope is 0 °-120 °.
The design concept of this bevel protractor is as shown in Figure 5:
According to designing requirement:
OA=OA′=R n
∠OAB=∠OA′B′=90°
Therefore, AB, A ' B ' are the center of circle with axle center O respectively Two tangent lines, A, A ' are two point of contacts. Angle equal be the angle value that index dial shows to central angle alpha one.According to geometric relationship:
R n=R- (φ)/2
This bevel protractor is different with the measuring method of existing setting-out and model, and its characteristics are that this bevel protractor is the numerical value and the position, point of contact of directly measuring the tube bending angle with the absolute magnitude method; This bevel protractor is different with fixed bevel protractor, and its characteristics are that this bevel protractor adopts vernier measuring tool to measure, and can measure tube bending inside radius arbitrary numerical value within the specific limits.The angle of bend and the point of contact of the pipe of different tube diameters, different bending radius, this bevel protractor all can be measured.
Accompanying drawing 1 is the structural drawing of pipe bevel protractor, and ratio is 1:3.Sequence number among the figure: 1-hand-screw spiral shell fourth, 2-spring leaf, 3-left comer plate, 4-bolt, 5-vernier, 6-index dial, 7-right corner plate, 8-spiral shell fourth, 9-left side slideway, 10-left side groove, the right slideway of 11-, the right groove of 12-, 13-axle, 14-spiral shell fourth, 15-wing nut.
Accompanying drawing 5 is design concept figure, among the figure:
AB-left comer chi base A ' B '-AO-left comer ulnar side limit, right corner chi base
A ' O-right corner ulnar side limit φ-measured tube diameter R-tube bending radius
R n-tube bending inside radius
The best way that realizes utility model is this pipe bevel protractor to be made the tandem product of different size, to satisfy the needs of different measuring scope.With specification " 130 pipe bevel protractor " is the best way that the example explanation realizes utility model.
The index dial radius of " 130 pipe bevel protractor " is 130mm, and what the centre hollowed out is the fan dial in the center of circle with axle (13).0 °~120 ° of measurement of angle scopes, 1 ° of indicating value is used numeral for per 10 °.Angular error is ± 5 ', the index dial surface irregularity is 3mm for 0.03mm thickness, material is T8.In order to prevent the groove wearing and tearing, arrive the index dial attenuate 0.2-0.3mm of edge apart from axle center 115mm.Index dial is manufactured with making sheet and the corroding method of taking pictures, and the degree of depth of groove corrosion is 0.2 + 0.08Mm, width are 0.2 + 0.03Mm, index dial is a white gravoply, with black engraved characters, it is 100 that the pilot hole φ 5 of slideway (9) and axle center hole φ 9, two hole centre distance are arranged on the index dial + 0.017Mm.
