Description

A rapid impact test aliquot marking line scriber

technical field

The utility model relates to the technical field of measurement, in particular to a scriber for dividing marking lines in a rapid impact resistance test.

Background technique

In the national standard GB-T 14152-2001 thermoplastic pipe impact resistance test method, it is proposed that when doing the impact resistance test of bellows, each sample should be equally divided along the circumferential direction of the pipe, and the equal division marks should be drawn along the length direction. line and numbered sequentially. In the actual test process, the aliquot method we can use is to measure with a ruler, because the number of equal parts for bellows with different diameters is different. The soft ruler has a thickness. After averaging, measure the line according to the average size. The measured value is larger than the actual value, and the distance to the last line will be smaller. Although the measured value of several times is the calculated value, the actual measured value is too large, which causes the last isoline to be too small, but this error is an inevitable error and there is no way to eliminate it.

Utility model content

The purpose of the utility model is to solve the shortcomings existing in the prior art, and proposes a scriber for dividing the marking line in a rapid impact resistance test.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

Design a scriber for quick impact test aliquot marking line, which includes a cylinder that constitutes the scriber, the upper end of the cylinder is fixedly installed with a dial, and the upper end of the dial is evenly engraved with scale lines, so the The side wall of the dial is axially evenly connected with a plurality of external fixing screws, the inner wall of the scriber inside the cylinder is threadedly connected with a plurality of internal fixing screws, and the bottom of the cylinder is fixedly connected with a chassis, so The bottom end surface of the chassis is evenly engraved with scale lines, the side wall of the chassis is circumferentially threaded with a plurality of external fixing screws, and the external fixing screws located on the dial and the external fixing screws located on the chassis are connected with Connect the wire.

Preferably, the outer wall of the cylinder is axially provided with a plurality of strip-shaped through holes for scribing.

Preferably, the outer walls of the chassis and the dial are engraved with scale lines of 0-360°, and the accuracy is 1°.

The utility model proposes a scriber for quick impact test equal division marking lines, which has the beneficial effects of changing the traditional method of measuring equal division marking lines, and solving the problem that due to the soft ruler itself has a certain thickness, the When dividing the gauge line, the measured distance includes the thickness of the soft ruler itself. In actual measurement, there is no way to accurately calculate the divided mark line. The method of measuring from the angle can effectively improve the mark line. Accurate depiction and improve work efficiency.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

Referring to Fig. 1-2, a scriber for quick impact test equidistant marking line includes a cylinder forming the scriber, the upper end of the cylinder is fixedly installed with a dial 4, and the upper end surface of the dial 4 is evenly engraved with scales Line, the side wall of the dial 4 is axially threaded with a plurality of external fixing screws 2, the inner wall 7 of the scriber inside the cylinder is threaded with a plurality of internal fixing screws 1, and the bottom of the cylinder is fixedly connected with a chassis 6, The bottom end surface of the chassis 6 is evenly engraved with scale lines, and the side wall of the chassis 6 is circumferentially threaded with a plurality of external fixing screws 2, located between the external fixing screws 2 on the dial 4 and the external fixing screws 2 on the chassis 6 A connecting wire 5 is connected. The outer wall of the cylinder is axially provided with a plurality of strip-shaped through holes for scribing. The outer walls of the chassis 6 and the dial 4 are engraved with a scale line of 0-360° with an accuracy of 1°.

In actual work, the scriber for the quick impact resistance test equalizes the marking line, and the impact test of the bellows is 50-63mm, 75-90mm, 110-125mm, 140-180mm, 200-250mm, 280-315mm in diameter The number of equal square marking lines of the bellows is 3, 4, 6, 8, 12, 16, if converted into angles, it is 120°, 90°, 60°, 45°, 30°, 22.5°, and the equal marks are marked in the impact test An angle ruler is set on the line scriber. The minimum scale of the angle ruler is 1° and the range is 360°. Then set 4 upper and lower fixing screws 1 and external fixing screws 2, and the screws are connected by connecting wire 5. , measure the diameter of the corrugated pipe before the test, draw a few bisectors for calculation according to the requirements of the national standard, calculate the angle according to the number of equidistant lines, and put the bellows into the impact test bisector marking line scriber , according to the calculated angle, adjust the angle of fixing the upper and lower fixing screws, and tighten the upper and lower fixing screws at the same time. The planning pen is drawn and numbered, and so on, the required aliquot marks can be drawn evenly. The method is simple and fast, and it can be truly even and equal.
