RU48407U1 - PIPE BUTTERFLY CUTTER METER - Google Patents

Abstract

The utility model relates to a tool for controlling the quality of cylindrical products, in particular, the cuts of a pipe end face. The meter of the kosin of the cut of the end of the pipe consists of a stand made with the possibility of installing perpendicularly forming the inner surface of the pipe, with which a rod is rigidly connected, perpendicular to the stand. The rod is equipped with a measuring scale. A leg is installed from the end opposite the rod to the rack, with the possibility of rotation on the axis of the rod and movement along it, and two pointers made to move along the scale of the rod and in contact with the leg. This meter kosin cut end of the pipe can improve the accuracy of measurements and reduce the complexity of their implementation by conducting direct continuous measurements from one installation and setup of the meter.

Description

The proposed utility model relates to a tool for controlling the quality of cylindrical products, in particular, the cut of the pipe end face.

Known thickness gage, including a rack with a fixed support perpendicular to the rack, and a steel rod perpendicular to the rack and fixed on it with a drum. (I.M. Mogilny. Technical drawing. Mashgiz. M., 1963, pp. 225-226.)

Reysmas are used for drawing parallel lines on parts during marking operations and measuring the dimensions of inaccessible parts, which cannot be measured with commonly used tools. Work with a surface gage on a scribe.

This tool can also be used to measure the cut of the pipe end face by installing the support so that the steel rod is perpendicular to the pipe generatrix. Then a guide is marked on the surface of the rotating pipe (a circle with a radius equal to the inner radius of the pipe).

In this case, the cut cosine is determined by performing numerous measurements with a ruler of the distances from the pipe end to the marked guide and then calculating the difference between the measured maximum and minimum measured distances. The disadvantages of the known tool:

- the cut cosine is determined by calculation (indirect measurement method), and not by direct measurements;

- in order to achieve sufficient measurement accuracy, it is necessary to conduct a significant number of measurements with a small step between measurements, which increases the complexity of such measurements;

- since the measurements are performed in steps (not continuously), the accuracy of the measurements is reduced;

- for marking the guide on the pipe, the latter must be rotated, which complicates the measurement process, increases the measurement time.

The technical problem solved by the proposed utility model is to create a tool for determining the cosine of a pipe end cut by direct measurements with reading its value directly from the instrument scale, which allows to reduce the complexity of the measurements and increase their accuracy.

The problem is solved due to the fact that in the meter of the kosin of the cut of the end of the pipe, including a stand made with the possibility of installing perpendicularly forming the inner surface of the pipe, and a rod rigidly connected to it, perpendicular to the stand, according to the utility model, the rod is equipped with a measuring scale, and with the end opposite to its fastening to the rack, a leg is installed with the possibility of rotation around the axis of the rod and movement along it, and two pointers made to move along the scale of the rod and in contact with the leg.

The utility model is illustrated by a drawing and a diagram, where Fig. 1 shows a diagram of performing measurements using the proposed tool; figure 2 presents a fragment of the meter Kosin cut end of the pipe - rod with a measuring scale, leg and two pointers.

The measuring instrument of the cut end of the pipe end consists of a stand 1 with a rod 2 rigidly fixed on it, on which a leg 3 is mounted with the possibility of rotation around the axis of the rod 2 and movement along it, and two pointers 4 and 5, made with the possibility of movement along the scale 6 of the rod 2 and in contact with the leg 3.

Measurement using the proposed tool is as follows.

The rack 1 with a rod 2 rigidly fixed on it is installed so that the rod 2 is directed along the generatrix of the inner surface of the pipe. Leg 3 moves along rod 2 until it contacts the end of the pipe, and pointers 4 and 5 until it contacts the leg 3. While keeping leg 3 in constant contact with the end of the pipe, one revolution of the leg is made around the axis of the rod 2. At the same time, the indicators 4 and 5 are rejected on the rod 2 from the starting position. The meter is removed from the pipe. Leg 3 is moved along the rod to contact with one of the ends of the pointers. On a scale of 6, the distance between the other end of the leg and the end of the pointer in contact with the leg is determined. This distance ΔL is the cut cosine of the pipe end.

Similarly, measurements are taken at the other end of the pipe.

This meter kosin cut end of the pipe can improve the accuracy of measurements and reduce the complexity of their implementation by conducting direct continuous measurements from one installation and setup of the meter.
