Abstract

The invention relates to the field of metal cutting, in particular to devices for controlling the integrity of the tool. The aim of the invention is the expansion of technological capabilities through the processing of shafts of various diameters. A clamping device in the form of the housing 1 and movable jaws 2, 3 is installed on the frame. A force head is placed on the frame carrying the tool 5. On the housing 1 an axis is fixed on which the rotating probe 7 is mounted. On the probe 7 a pin 8 is fixed interacts with the sponge 2 when it is moved by means of a lead 9 fixed on the sponge 2. The probe 7 is equipped with a spring 10 fixed on the housing 1. A non-contact switch 11 is installed on the housing 1, which during the removal of the lips 12 operates with the probe 7. silt (L 4

The invention relates to the machining of metals, in particular to devices for monitoring the integrity of the tool, and can be used IB machine tools for machining shaft ends.

The purpose of the invention is the expansion of technical capabilities (1ological capabilities due to the processing of shafts of various diameters. I Figure 1 schematically shows a cutting machine; Fig. 2 - section A-A in Fig. 1; Fig. 3 - section -B in Fig. 2,

 The cutting machine contains; tannin (not shown), on which the fixture is installed, made in the form of body 1 and the base Sponge 2 and 3. The power head 4 is also positioned on the support frame, the tool-5 is located in the spindle. axis 6, on which a probe is mounted with the possibility of a recess. 7. Pin il is attached to the probe. During the supply of the jaws 2 and 3, the pin interacts with the sponge 2 by means of the leash 9 attached to it 9. 1 | pack 7 is equipped with a spring 10 fixed to the housing 1 and tending to return it to its original position. On housing I, there is a contactless g: Switch 1 1, which, during the junction of the jaws, interacts with barb 7.

The dotted line shows the position of the machine organs at the time of unclamping 2 | clamping device machined: (etal and control the integrity of the cutting tool ib of the tool ,.

The machine operates in an automatic 1 |; hook as follows. With the help of ify6oK 2 and 3, the workpiece is clamped, then the 4th lead of the power head 4 is fast, and the working feed is communicated to it. With an atom using a cutting tool 5, the centering hole in the part is machined.

After the end of processing, power head 4 moves back to its initial position, after which the parts are unclamped. In this case, the jaws 2 and 3 diverge. While the sponge 2 is moving, the leash 9 releases the pin 8 of the probe 7. Under the force of the spring 10, the probe 7 rotates counterclockwise and with one end touches the cutting tool MeVA 5. If the tool is intact, the probe 7 stops. In this case, the second end of the probe 7 does not reach the switch 11 and the cycle continues. After the installation of the new billet (shaft) of the sponge 2. and 3, it collapses. In this case, the lead 9 attached to the sponge 2, moving to the right, rotates the probe 7, bumping on the pin 8 and overcoming the force of the spring 10.

In the event that the drill turns out to be broken, probe 7, turning counterclockwise, passes through the center of the centering drill and acts on switch I1 and the processing cycle is interrupted.

The use of the proposed machine provides work in the whole range of diameters of the workpiece.
