Description

The invention relates to technical measurements and can be used to determine the length of the reference profile in the profilogram.

A device is known for determining profile parameters by a profile-5 gram, comprising a housing with guides, a movable frame along them with its guides, perpendicular to the guides of the housing, a slide mounted on the carriage, mounted on the carriage, with a vizier, A computational node connected to the carriage, including a movable element located on the carriage and a fixed element located on the body. The computational node is made in the form of a taper pair TsILI NDR G 1.

The disadvantage of this device is the impossibility of determining 20 with a sufficient accuracy of the length of the reference line of the profile from the profilogram.

The aim of the invention is to improve the accuracy and performance in determining the length of the reference line 25 of the profile on the profilogram.

The goal is achieved by the fact that in a device for determining profile parameters by profilogram, comprising a housing with guides,

30 a movable frame with its guides, perpendicular hull guides, a carriage moving along the frame guides, a carriage bar mounted on the carriage with viewfinder, and a computational 35 node connected to the carriage and including a movable element located on the carriage and stationary the element located on the body, the support plane is made on the frame, the stationary element of the computing node is made in the form of endless threads with labels tensioned through equal spacers parallel to the body and track guides d boiling above the reference plane, and IG Petritskaya po- 45 knots computing element is configured in the form of tape, binding with the carriage frame and situated at a distance from the reference plane for pressing Nachod schihs rn below the ribbon threads to the reference plane.

FIG. 1 shows the device, a general view; ya fig. 2 is a section A-A in FIG. one.

The device for defining profile parameters by profilogram includes a housing 1 with guides 2, a frame 3 with guides 4, a carriage 5 moving along the guides of the frame, a bar 6 with a viewfinder 7, a reference plane 8 a fixed element of the computing node, made in the form of a row endless threads 9 with marks 10, pulled on freely rotating pulleys 11 and a movable element of the computing unit, made in the form of a tape 12, wound on a spring-loaded drum 13. The free end of the tape is fixed on 3. On the case 1 a scale bar 14 is installed.

The device works as follows.

The housing 1 of the device is installed adjacent to the profilogram 15 under study parallel to the centerline of the profile. Combine viewfinder 7 with the beginning of the profilogram and hold the viewfinder for the bar 6 manually across the entire profile curve. In this case, the frame 3 moves along the middle line of the profile, and the carriage 5 across the center line of the profile. When moving the reticle 7 down the profilogram, the plank B, moving the carriage 5 along the guides of the frame 3, causes the reel 12 to unwind from the reel 13; which presses the endless NIII 9 to the supporting plane 8, with the result that the pressed yarns move together with the frame in the longitudinal direction. When moving upwards, the presser belt 12 releases endless threads 9, which, when the frame 3 is pressed, remain stationary in the longitudinal direction. As a result, the labels 10 are moved together with the endless threads 9 by an amount equal to the sum of the lengths of the sections of the profile support line at the level corresponding to the location of the endless thread. The determination of the value of the reference line of the profile is made by the position of the marks 10 relative to the scale of the swarm of the ruler 14.

As a result of the application of the proposed device, the productivity and accuracy of determining the length of the profile support line by the profilogram are improved.
