Abstract

The invention relates to a machine tool industry and can be used in the systems of automatic control of aggregate machines and automatic lines for determining the presence of machined holes and indirect control of tool breakage. The aim of the invention is to simplify the design and increase the reliability of the device response by eliminating the issuance of spurious signals. The support element with spring-loaded push-pull probes 3 is fixedly mounted on the device body. The actuator is made in the form of a progressively moving cross bar 9 acting on the probes 3. The cross head 9 is driven from the power cylinder 4 through levers 7, springs 10 and rolling pins 6. With all the controlled holes at the end of the cross bar 9, the flags enter the zone action of the sensors 12. In the absence of at least one of the monitored holes, one HJ skalok 6, due to the activation of the spring 10, does not reach the final position. Traverse 9, hinged on the rolling pin 6, becomes at an angle to the axis of the part being monitored, and one of the flags does not fall within the range of the sensor. The absence of the sum of the signals of both sensors with the signal of the KOHiia sensor of the stroke of cylinder 4 indicates the presence of raw holes. 3 il. tt v)

The invention relates to a machine tool industry and can be used in automatic control systems for modular machines and automatic lines for determining the presence of machined holes and indirect control of tool breakage.

The purpose of the inventions is to simplify the design and increase the reliability of the device operation by eliminating the issuance of spurious signals.

FIG. 1 shows a device, a plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The device includes a housing 1, on which the support element 2 is fixed with spring-loaded axial sliding probes 3 and the power cylinder 4 of the actuator actuator 5.

The latter contains two parallel rolling pins 6, moving with the help of levers 7 in slide bearings 8,

11 enters the zone of operation of sensors 12. The sum of the signals of both sensors 12 with a sensor signal (not shown) of the end of the stroke of cylinder 4 indicates the presence of all of the monitored holes and is a signal to retract crosshead 9 backwards. After the termination of the action of the crosshead 9 on the probes 3, the latter, under the action of their springs, return to their original position.

In the absence of one of the controlled holes, or in the presence of the yoke 9 broken in the tool hole, encountering an obstacle in the form of a non-melting probe 3 in the hole, it becomes at an angle to the longitudinal axis of the tested part. At the same time, until the end of the stroke of the cylinder 4, the rolling pin 6, located closer to the non-recessed probe 3, remains stationary — the lever 7 slides along the rolling pin 6, compressing the spring 10, the second

The absence of a signal from one or both sensors 12 in total with the sensor signal of the end of the stroke of the cylinder 4 indicates that contactless sensors 12 are in the presence of all the monitored holes.

The part 13 is held in the test position by means of a clamp 14 (the clamp actuator is not shown).

The device works as follows.

During the working stroke the cylinder 4 rotates the levers 7 relative to the axis of their fixation. The levers 7 operate with the help of springs 10 on rolling pins b, moving the latter together with the crossbeam 9 towards the controlled part 13, with

There are no open holes.

Invention Formula A device for controlling the presence of openings, comprising a housing with a supporting element with probes located on it moving in the axial direction, and hence the traverse 9 moves parallel to the extension 40, characterized in that it is longitudinal to the part 13. enhancing the reliability of the operation, the traverse of the traverse 9 acts on the pivots and simplifies the design, the supporting element of the moving movable probes 3, which, as a matter of fact, are fixed on the body, and the fractional resistance of its springs, the input executive mechanism is equipped with a traverse of the machined holes of the part 13. Soi, installed with the possibility of interdependence. 0 fi 11 enters the zone of operation of sensors 12. The sum of the signals of both sensors 12 with a sensor signal (not shown) of the end of the stroke of cylinder 4 indicates the presence of all of the monitored holes and is a signal to retract crosshead 9 backwards.
