Description

The utility model relates to the field of mechanical engineering, in particular, to turning machines for turning without rolling out wheel pairs of traction rolling stock.

A well-known universal machine for turning without rolling out wheel pairs of electric locomotives, diesel locomotives and motor wagons, containing a support mounted on a bed, drives for longitudinal and transverse feeding of a support, lifting devices, a lubrication station, a control panel ("A universal machine for turning without rolling out wheel sets of electric locomotives, diesel locomotives and motor wagons. "Passport A.41.01.00 PS).

The turning of the wheelset profile with this machine is carried out using manual control, which determines its main drawback - low processing accuracy due to dependence on the human factor.

The technical result achieved by using the proposed utility model consists in increasing the accuracy of turning of the wheels of the traction rolling stock and reducing the influence of the human factor on the quality of processing, as well as in ensuring the repeatability of the processing parameters.

The specified technical result is achieved by the fact that the machine for turning without rolling out the wheel pairs of the traction rolling stock, containing a support mounted on a bed, drives of longitudinal and transverse feed of the support, lifting devices, control cabinet, hydraulic station, lubrication station, control panel, is equipped with a wheel pair fixing mechanism from axial displacement, a device for automatic measurement of the wheelset profile and caliper base, an automatic control device for lifting devices equipped with measuring mi sensors and the CNC system comprising a device for measurement of the wheelset profile and calculate modes

cutting, with the ability to display, store and output this data to peripheral devices.

The presence of automatic devices for automatic measurement of the wheelset profile, caliper base, control of lifting devices and the CNC system provides automatic operation according to the selected program, allows you to store and transmit measurement results to a distance.

The utility model is illustrated by drawings, on which:

Figure 1 - General view of the proposed machine for turning wheel sets.

Figure 2 - View of the machine in operation with an installed locomotive.

The machine for turning without rolling out the wheel pairs of the traction rolling stock (Figure 1) contains a frame 1 on which a support 2 is mounted with the ability to move along the guides 3 and 4 using drives of longitudinal and transverse feed, lifting devices in the form of jacks 5 and 6, an electric cabinet , hydraulic power station (not shown), lubrication station 7, control panel 8.

A feature of the machine is that it is equipped with a mechanism for fixing the wheel pair from axial displacement, containing locking rollers 9 and 10, a device for automatically basing the caliper and automatic measuring the profile of the wheel pair with a touch sensor, a device for automatically controlling lifting devices (jacks 5, 6) equipped measuring sensors, and an CNC system built into the control cabinet (not shown) and containing a device for measuring the profile of the wheelset and calculating cutting conditions, with the ability to display, storing and outputting this data to peripheral devices.

The work of the machine for turning wheeled pairs, according to the claimed utility model, is as follows.

Machine control is carried out from the central console 8, located directly on the machine, through the operator panel 11.

The operator panel 11 is designed to display the operating modes of the machine and enter processing parameters. The panel has alphanumeric buttons, input and cursor control buttons, and freely programmable buttons. After turning on the introductory machine, the program is loaded and the CNC system is tested. The "Main Menu" window will appear on the control display. After that they switch to the “Setup” mode.

Before installing the locomotive 12 (Figure 2), on which it is required to turn the wheels 13, 14, the jacks 5, 6 and the fixing rollers 9, 10 of the machine are set to the initial position with the buttons SB9 and SB11.

The locomotive is fed to the machine, and the axle box axles are mounted above the jacks 5, 6 with an accuracy of no worse than ± 10 mm. Using the SB14 button and, if necessary, the SA4 switch, the jacks are brought under the axleboxes and the wheelset is raised 10-15 mm above the movable rails. Then the movable rails are removed and the jacks lower the jacks by 20-40 mm with the SB11 button. Fixation rollers are brought to the wheels and make sure that the rollers go to the untreated part of the inner edge of the bandage by at least 10-15 mm. If necessary, lower or raise the wheelset.

Finally, the wheelset is clamped by the locking rollers 9, 10. In this case, the locking rollers are pressed with a certain force to the wheel, and then automatically turn off. After pressing with rollers, the movement of the jack up and down is blocked.

Next, measure the profile of the bandage of the wheelset and, if necessary, align the axis of the wheelset. To do this, you must exit from the "Setup" mode to the "Main menu" mode and turn on the "Automatic" mode.

By pressing the SB12 "Start selected operation" button, the measurement cycle is started. When measuring, the touch sensor extends and alternately touches the characteristic points of the band profile of the right wheel and then the left wheel. At the end of the measurement cycle, the display shows the coordinates of the tops of the flanges of the wheels, the coordinates of the ends of the wheels, the span distance. If necessary, alignment is performed.

At the end of the measurements, they start turning the wheels.

To do this, go into the "Processing" mode.

To select a mode, press the F1 button and select the type of processing: "Full" or "Partial".

In the input windows, the processing order of the wheel (right, left) is established, the profile is selected and, if necessary, the metal removal value is entered.

To start the processing cycle, press the button SB12 "Start the selected operation". You can interrupt processing by pressing the SB13 "Stop selected operation" button.

If the wheel does not require complete processing, it is possible to produce partial processing from any point on the profile.

All necessary technological parameters are displayed on the display of the central console. Information on the status of the machine is also displayed, errors are diagnosed, and messages to resolve them are displayed.

Based on the measurement results, the control system calculates the amount of metal removal for each wheel while ensuring equal diameters in the driving circle, after which the profile is turned.

The profile to be turned is made by selecting from the options shown on the display.

The application of the control system ensures that the results of the preliminary measurement of the wheelset and the parameters of the turned wheelset are displayed on the operator panel screen to form the electronic passport of the product.

The utility model can be widely used in machine tool construction for the production of new machines designed to restore worn wheelsets without removing them from the locomotive.
