Description

The utility model relates to measuring equipment and is intended for diagnostics of automatic coupling of railway vehicles, namely to check the width of the window for the lock and lock holder in the throat of the automatic coupling housing before putting it into operation.

The prior art devices for measuring the geometric parameters of the throat of an automatic coupler (RU, 40464, U1 04/13/2004), according to which due to the use of interchangeable plates, they provide high accuracy of measurements and increase the operating life, while there is no need to design counter templates. The use of interchangeable plates, ensuring the accuracy of measurements, at the same time leads to a complication of the measurement process due to the possible loss of certain plates during operation.

There is also a template for monitoring the profile of products (A.S. USSR, 196358, 03/17/1967) containing a measuring carriage, a ruler along which the carriage with a contact pin moves, the position of which is counted according to the nonius of the carriage, while for increasing productivity on the template In addition, a number of contact pins are installed and all fonts are frictionally fixed to the ruler regardless of the carriage. The design of the template is difficult to operate, requires constant adjustment and adjustment.

The scale is calibrated so that the readout on the risk applied to the engine corresponds to the value of the angle determined from the ratio. Thus, in order for the scale to measure a given angle, it is necessary to properly position the motors relative to each other and to scale the scale in accordance with the desired ratio.

The disadvantages of the known measuring devices in addition to what has already been said are the relative complexity of their structural implementation, and, consequently, the complexity of their operation and increased cost. In addition, well-known patterns cannot be applied to verify the parameters of a newly manufactured or rebuilt automatic coupler lock, since the known solutions are designed for specific parts that are not related to automatic couplers.

The closest analogue of the claimed technical solution has not been identified.

The objective the utility model is aimed at is to increase the accuracy of measurements and the quality of diagnostics of the tested auto coupler parts, such as CA-3 railway vehicles, by improving the quality of the measuring surfaces and the automatic coupler parameters of the assembly, which, as a result, is essential for improving safety operation of railway transport. The technical result consists in reducing the measurement error due to the degree of its roughness (high surface cleanliness), as well as the degree of wear of the measuring surfaces, in addition, the design of the template is devoid of stress zones, stress concentrators, angles between the measuring surfaces, which eliminates the possibility of surface stresses and, as consequence, flatness, linearity.

To achieve a technical result, the template 1 for checking the window 2 for the lock and the lock holder in the throat of the body 3 of the automatic coupler 4 is made of carbon metal of high-quality structural steel in the form of a flat part of an H-shape 5, one legs of the same name are made respectively with a passage end 6 and a passage ledge 7, and other legs of the same name, respectively, with a passage step 8 having an impassable step 9, and with an impassable protrusion 10, on the outside of which a protrusion 11 is arranged, which can be abutted in the st nku 12 of the throat 13 of the automatic coupler, and on the other external side there is a flat rib 14 with the possibility of contacting with the inner surface 15 of the small tooth 16, and at the passage end 6 there is a roller 17 with the possibility of placing between the edges 18, 19 of the window 2 for the automatic coupler lock, while the working surfaces of the template, namely the passage step, the passageway, the flat rib, the roller, are made with a roughness of 2.5 Ra, and subjected to cementation or processing by high-frequency currents to obtain a hardness of 56-64 HRC, and in the corner zones of the working surfaces made elements 20 compensation of stresses in the form of recesses.

There are other possible embodiments of the utility model, according to which it is necessary that:

- steel of the grade St.45 or St.45XH was used as the material;

- the template was made with a thickness of 6-11 mm;

- voltage compensation elements are made in the form of recesses in the corner zones of the measuring hole.

The template is a checkpoint and is designed to check the window for the lock and lock holder in the throat of the automatic coupler housing.

According to a utility model, the template 1 for checking the window 2 for the lock and the lock holder in the throat of the body 3 of the automatic coupler 4 is made of carbon metal of high-quality structural steel in the form of a flat part of an H-shape 5. The same legs are respectively made with a passage end 6 and a passage ledge 7, and other legs of the same name, respectively, with a passage step 8 having an impassable step 9 and with an impassable protrusion 10, on the outside of which a protrusion 11 is arranged, which can be abutted against the wall 12 of the throat 13 coupler. Moreover, on the other external side there is a flat rib 14 with the possibility of contacting with the inner surface 15 of the small tooth 16. At the passage end 6, a roller 17 is located with the possibility of placing between the edges 18 and 19 of the window 2 for the automatic coupling lock. In this case, the working surfaces of the template, namely the passage step, impassable protrusion, flat rib, roller, are made with a roughness of 2.5 Ra, and subjected to cementation or processing by high-frequency currents to obtain a hardness of 56-64 HRC, and in the corner zones of the working surfaces stress compensation elements 20 in the form of recesses.

Moreover, in the process of control, one and the other of the connected parts are recognized as fit.

The device operates as follows.

Template 1 is for the following checks.

Checking the width of the middle wide part of the window 2 in the throat 3 for the legs of the lock holder.

The check is carried out according to the height of the pocket for the claws of the lock holder not reaching 15 mm to the upper and lower edges of the pocket.

When checking as shown in figure 3-7, the width of the middle part of the window 2 is recognized as correct if the passage end of the template 1 freely enters the pocket of the housing until the template 1 stops in the transverse wall of the pocket for the lock holder, and the opposite passage of the template 1 does not enter the case 3 or partially enters, but not completely against the protrusion 11 "a" of the template 1 into the wall of the throat 13. In this case, the template 1 is guided by an even edge 14 along the inner surface 15 of the small tooth 16 and is perpendicular to it.

Checking the width of the top of the window in the throat 13 for the lock.

Checking the upper part of window 2 is carried out in height, not reaching 10 mm to the upper edge.

During the Check, as shown in Figs. 8-11, the width of the upper part of the lock window 2 is considered correct if the passage part of the stepped end of the template 1 passes freely and the non-passage part does not pass between the edges of the upper part of the window 2. In this case, the template 1 should be perpendicular to the inner wall of the small tooth 16 and pressed against it by an even edge 14 of the base.

The hitch 4 is not suitable if the passage step 8 does not pass, or vice versa, the passage step 9 of the template 1 passes between the edges of the upper part of the window.

Checking the width of the bottom of window 2 in the throat 13 for the lock.

Checking the bottom of window 2 is carried out in height, not reaching 7 mm to the bottom edge.

When checking, as shown in Fig.12-17, the width of the lower part of the window 2 for the lock is considered correct if the through end of the template 1, on which the roller "b" is mounted, completely passes between the edges of the window 2 until the adjacent protruding end of the template 1 in the wall of the throat 13, and the impassable roller "b" does not pass between the edges of the window 2.

The hitch case 4 is unsuitable if the passage end of the template 1 does not extend completely between the edges 18 and 19 of the lower part of the lock window 2 or the pass-through roller 17 passes between these edges.

The use of the utility model makes it possible to increase the accuracy of measurements and the quality of diagnostics of the checked parts of the automatic coupling of SA-3 railway transport by improving the quality of processing of measuring surfaces, which as a result has a significant impact on improving the safety of operation of railway transport.
