EPS The invention relates to a machine tool industry and can be used when machining holes on aggregate machines. Known devices for monitoring the presence of drilled holes in the parts are a probe or a group of parallel probes that are moved from the drive and mounted on a spring-loaded carrier element. The device contains probes mounted on a plate of a spring-loaded quill with the possibility of translational movement from the hydraulic cylinder flj. However, the known device did not rto e to simultaneously monitor the presence of drilled radial and axial holes. The aim of the invention is to expand the technological capabilities of the device, namely the monitoring of the presence of drilled radial and axial holes. This goal is achieved by the fact that, in a device containing sensors and associated with a control plate driven by a two-way hydraulic cylinder, test probes, in the internal cavity of the hydraulic cylinder stem is mounted a pivot axially spring-loaded on one side, the end of which has a base with movable spring-loaded radial probe holders and fixed axial probe holders and an adjustable stop, limiting the axial movement of only bodies in contact with the controlled part Pour, and copiers interacting with radial probe holders when in contact with the stop of the pusher with a controlled part are sorted at the end of the double-sided rod, and are mounted with the possibility of movement relative to the holders and interacting with the sensors. FIG. 1 shows a device for monitoring the presence of drilled holes, the vertical section in FIG. 2 is a view A of FIG. one; in fig. 3; view B in FIG. 2, the slider is shown in the controlled hole in FIG. 4 the same, the device at the time of the signal in the electric furnace. The device for checking the presence of drilled holes contains (fig. Bracket 1 with a hydraulic cylinder 2 fixed on it 432, within which a double-sided rod 3 moves with a spring 4 fixed on one side and a spring 5, spring-loaded on one side, supporting the base 6, on which are movable | spring-loaded springs 7 radial holders 8, with probes 9 and stationary axial holders 10 with probes 11, as well as an adjustable stop interacting with the test piece 12. Copier 13 fixed on the rod rises up radial holders 8, with which the brackets 14 are connected with the sensors 15 and the petals 16 interacting with the latter, are mounted on the spring-loaded springs 17 of the axis x 18. Levers 19. With the rod 3, the guide pins 20 and 21 are rigidly connected, and bracket 1 fixed sensors 22 and 23, interacting with the petal 24. The controlled part 25 Installed in the clamping device of the rotary table. The device operates as follows. . When the oil is fed into the upper cavity of the cylinder 2, the double-sided rod 3 begins to move downward along with the cam 13 (Fig. 1), rolling pins 20 and 21 and the petal 24. At the same time, the spring 5 spring-loaded pusher 5 with the base 6 mounted on it, the holder mi 8 and 10, probes 9 and 11, adjustable stop 12, brackets 14, sensors 15, petals 16, springs 17, axles 18 and levers 19. When the stop 12 reaches the controlled part 25, the pusher 5 with base 6 stops, rod 3, continuing movement, compresses the spring 4, / simultaneously on the ledges radial s holders moved against vertical grooves copier 13, whose inclined surfaces push the holders 8 with the groove 9 probes to the workpiece center 25. At the end of the stroke 3, all radial and axial probes are within the controllable apertures (FIG. 3). In the absence of a hole or a tool breakage (fig. 4), the holder 8 by the copier 13 moves to the right, while the hoop 9 is stationary, i.e. the holder 8 moves relative to the probe, and the petal 16 attached to the lever 19 rotates on the axis 18, compresses the spring 17 and enters the slot of the sensor 15, giving a signal to the electrical circuit. The machine stops with a certain delay in the time taken by the circuitry. When machining parts on the turntable, the machining process proceeds in parallel with the process of checking the presence of drilled holes, so a pause is necessary to remove the remaining cutting tools from the cutting zones for the maximum distance and to ensure reliable operation of the device. From the sensor 23, the command is received to raise the rod 3 (Fig. 1). The copier 13 moves up with it, releasing the holders 8 with probes 9 pressed to the initial position by the springs 7. The base 6 remains at this time to press 1m spring 4 through adjuster 434 adjustable stop 12 to the tested part 25. After the upper pusher nuts 5 touches the rod 3, the latter pulls the pusher 5 with the base 6 and the holders 8 and 10 upwards, and the device returns to its original position. The sensor 22 sends a signal to the electrical circuit about. end of the cycle. The movement of the axial holder 10 (Fig. 1) is carried out directly. The movement of the sensor on the axial holder 10 is similar to the movement of the base 6, similarly to the operation of the sensor 15 of the radial two-step. The implementation of the invention significantly expands the technological capabilities of the device, providing simultaneous control of the presence of radial and axial holes drilled into the part.
