Abstract

The utility model relates to the technical field of measuring tools, in particular to a dedicated pipe orifice obliquity vernier for measuring the pipe orifice obliquity of a pipe after being processed by a machine. The dedicated pipe orifice obliquity vernier comprises three parts including an angle square (1), a vernier (2), and a sliding block (3). Scales are respectively carved on the vernier (2) and the sliding block (3), so as to conveniently and precisely measure the pipe orifice obliquity of the pipe. The utility model has the advantages of convenient use, simple and clear reading, and high measuring accuracy and measuring efficiency, and can excellently meet the requirements of the measuring and examining in production.

Description

Special-purpose mouth of pipe degree of tilt vernier scale

Affiliated technical field

The utility model relates to the measurer technical field, is specially adapted to measure the special-purpose mouth of pipe degree of tilt vernier scale of pipe mouth of pipe degree of tilt after machining.

Background technology

In the commercial production, often run into the problem of the mouth of pipe degree of tilt that needs the measurement pipe.As in the station boiler industry, need measure the mouth of pipe degree of tilt when pipe and pipe splicing through pipe behind the machining groove.Existing way is: use a wide angle square to lean against on the tube wall and the mouth of pipe of pipe, and then use clearance gauge to fill in the mouth of pipe degree of tilt (see figure 3) that pipe is measured in gap between the mouth of pipe of wide angle square and pipe.This method measuring error is big, efficiency of measurement is low, can not satisfy large-scale production to Testing requirement.

The utility model content

The purpose of this utility model provides a kind of precision height, reading special-purpose mouth of pipe degree of tilt vernier scale directly perceived, simple to operate.

The technical scheme that its technical matters that solves the utility model adopts is: this special-purpose mouth of pipe degree of tilt vernier scale comprises angle square, vernier scale, slide block.Vernier scale is installed on the slide block and can slides up and down along slide block, and slide block is installed on the angle square and can horizontally slips along angle square, and the glide direction of the two is vertical each other, and a step surface is arranged on the angle square, is carved with scale on vernier scale, the slide block respectively.Because slide block is contained on the angle square, vernier scale is contained on the slide block, and the glide direction of the two is vertical each other, earlier angle square is leaned against on the tube wall and the mouth of pipe of pipe during use, again the vernier scale end face is contacted (see figure 2) with the mouth of pipe of pipe, can measure the mouth of pipe degree of tilt of pipe.

The beneficial effects of the utility model are: special-purpose mouth of pipe degree of tilt vernier scale is convenient and practical, reading is simple and clear, measuring accuracy and efficiency of measurement height, be well positioned to meet production to measure, the demand of check.

1. angle squares among the figure, 2. vernier scale, 3. slide block, 4. pipe, 5. wide angle square, 6. clearance gauge.A, B, three faces of C are three faces on the angle square (1), and the D face is the end face of vernier scale (2).δ is the mouth of pipe degree of tilt of measured pipe.

Embodiment

In Fig. 1, this special-purpose mouth of pipe degree of tilt vernier scale divides three parts: angle square (1), vernier scale (2), slide block (3).Vernier scale (2) is installed on the slide block (3) and can slides up and down along slide block (3), slide block (3) is installed on the angle square (1) and can horizontally slips along angle square (1), the glide direction of the two is vertical each other, one step surface (B face) is arranged on the angle square (1), the B face is parallel to C face and D face, and the A face is perpendicular to B face and C face and D face.Vernier scale (2), slide block are carved with scale respectively on (3), vernier scale (2) is identical with general vernier caliper with principle with graduated structure on the slide block (3), and the end face (D face) of vernier scale (2) is just in time appeared on the stage terrace (B face) in one plane with angle square (1) during both scale zero line alignment.

In embodiment illustrated in fig. 2, the angle square (1) of special-purpose mouth of pipe degree of tilt vernier scale is leaned against on the tube wall and the mouth of pipe of pipe (4), be that the A face contacts fully with the tube wall of pipe (4), the B face contacts fully with the mouth of pipe of pipe (4) simultaneously, sliding slider (3) and vernier scale (2) make the end face (D face) of vernier scale (2) contact fully with the mouth of pipe of pipe (4) then.Because vernier scale (2) is installed on the slide block (3) and can slides up and down along slide block (3), slide block (3) is installed on the angle square (1) and can horizontally slips along angle square (1), the glide direction of the two is vertical each other, the glide direction of slide block (3) is parallel to the B face, the glide direction of vernier scale (2) is parallel to the A face, the A face is perpendicular to the B face, the end face (D face) of vernier scale (2) is just in time appeared on the stage terrace (B face) in one plane with angle square (1) during the alignment of scale zero line on vernier scale (2) and the slide block (3), so the scale from the vernier scale (2) can directly be read the mouth of pipe degree of tilt δ of pipe (4).

Figure 3 shows that current measuring methods: use a wide angle square (5) to lean against on the tube wall and the mouth of pipe of pipe (4), and then use clearance gauge (6) to fill in the mouth of pipe degree of tilt that pipe (4) is measured in gap between the mouth of pipe of wide angle square (5) and pipe (4).

Claims

1. special-purpose mouth of pipe degree of tilt vernier scale, comprise angle square (1), vernier scale (2), slide block (3), it is characterized in that vernier scale (2) is installed on the slide block (3) can slide up and down along slide block (3), slide block (3) is installed on the angle square (1) and can horizontally slips along angle square (1), the glide direction of the two is vertical each other, one step surface (B face) is arranged on the angle square (1), the B face is parallel to C face and D face, and the A face is perpendicular to B face and C face and D face, vernier scale (2), slide block is carved with scale respectively on (3), and the end face (D face) of vernier scale (2) was just in time appeared on the stage terrace (B face) in one plane with angle square (1) when both scale zero lines alignd.
