Abstract

The invention makes it possible to increase the measurement accuracy and expand its range. The device contains brackets, one of which is mounted on the housing with the possibility of reciprocating movement. On the brackets fixed measuring rollers. There is a unit for limiting rolling movements and a device balancing element. The unit for limiting movements is made in the form of a C-shaped bracket 12, a cross member 13 fixed on its ends. The support rollers 14 are mounted on the ends of the transverse 13. The balancing element in the form of a load 16 is placed on the shelf of the C-shaped bracket 12 along its axis of symmetry. 1 hp f-ly, 4 ill.

Description

(L

- "

The invention relates to a measurement technique and can be used to measure the linear dimensions of the cross section of rolled steel, preferably shaped.

The purpose of the invention is to show the accuracy of measurements and expand the range of measurements.

FIG. 1 shows a device for measuring, side view; in fig. 2 - the same, front view; in fig. 3 shows the orientation of the device when measuring the thickness of the steel shelf; in fig. - the same, when measuring the wall thickness of the rolled products.

A device for measuring the dimensions of the section of shaped steel includes a housing (base) G, movable and fixed brackets 2 and 3, a slider

4, rigidly mounted on a movable bracket 2, measuring rollers

5, fixed respectively on brackets 2 and 3. Radial ball bearings can be used as measuring rollers 5. Traverse 6, attached to the housing 1

at the time of measurement using fixing screws 7 with lock nuts, handle 8 serves to transfer the device. A sleeve 9 with an adjusting screw, a spring, a plunger and an indicator of 10 linear displacements, mounted on the traverse by means of an adjusting screw 11, is placed in the traverse 6.

On case 1 with the possibility of reciprocating. On movement, a node for limiting the transverse movement of the measured rolled steel is installed in the form of a C-shaped bracket 12, at the ends of which the crossbar 13 is rigidly fixed, carrying support rollers 14 at their ends, installed symmetrically on both sides of the measuring rollers 5. Support rollers 14 on the outer surface they have V-shaped annular grooves 15. On the shelf of the C-shaped bracket 12 along the axis of symmetry there is a balancing element 16 in the form of a weight 16. The mass of the cargo 16 is chosen in such a way that at the time of measurement it balances a device in a plane passing through the contact lines of the forming surfaces of the measuring rollers 5 with the surface of the measured element of the section of the shaped steel.

The device works as follows.

The device is brought into contact with the measured profile 17 and is moved along it. In the measurement process, the measuring roller 5 of the movable crown of theine 2 moves along the housing 1, causing the indian pin K) of K) to move, the readings of which are read directly or can be recorded as an alternating signal.

When measuring the wall thickness of the shaped steel, such as a beam, channel, etc., the support rollers 14 move along the shelf of the measured profile (Fig. 3). When measuring the thickness of the shelves (flanges) of the profile, the support rollers 1A move along the edge of the profile flange, which contacts the annular V-shaped groove 15 of the roller 14 (Fig. 4). At the same time, the presence of a balancing weight 16 fixed on the shelf of the bracket 12, i balances the device in a plane parallel to the axis of the measuring rollers.
