(5) DEVICE FOR CRUSHING CHIPS WHEN FLOWING MASSIVE PARTS

V

The invention relates to a machine tool industry, and more specifically to machine tools with chip breaking devices.

A device for crushing chips, containing a caliper, a slider with a notched tool mounted for movement in the guides of the housing fixed to the caliper, and a drive for moving the slider t are known.

The disadvantage of this device is the complexity of the design.

The purpose of the invention is to simplify the design of a device for crushing chips when turning massive parts.

The goal is achieved by the fact that the notched tool is installed in a slider with the possibility of swinging on an axis parallel to the axis of rotation of the workpiece, the slider is mounted for movement and elastically raised relative to the body in a direction perpendicular to the axis of rotation of the workpiece. cam mechanism.

FIG. 1 shows the proposed device, the cut; in fig. 2 same plan view; in fig. 3 is a section A-A in FIG. one.

The device for crushing chips contains the tool 1, the holder 2, the slider 3, the springs k and 5, the pe10 the adjusting screw 6, the housing 7, the axis 8, the roller 9, the cam 10, the axis 11, the bevel gears 12, the shaft 13, the spur gears 1 , drive 15.

The cutting tool 1 is a rod made at the end of the wedge; tool 1 is mounted in the holder 2 by means of a bolt 16. The holder 2 is installed half a zune 3 by means of an axis 17 and the coins are turned around it in a vertical plane. The holder 2 is pressed against the surface of the slide by spring 4. 398845 The slide 3 is mounted in the direction 18 of the body 7, directed perpendicular to the axis 17 of the holding holder 2 in the slide 3. The spring 5 serves to move the slide in the direction of the workpiece. spring 5 plots into the slider, and another into the adjusting screw 6 installed in the housing 7 The adjusting screw 6 installed in the housing 7 serves to adjust the pressing force of the spring 5 which determines the impact force of the tool 1 on the workpiece. roller 9 is installed. The roller interacts with cam 10. Cam 10 serves to press slider 3 from the workpiece and has steps 19 on its curvilinear surface. Cam 10 is mounted on axis 11 fixed in the housing by means of bearings. Axis 11 by means of a pair of bevel gears 12, shaft 13, a pair. cylindrical gears 14 are connected 25 with a drive, 15, mainly an electric motor. The horn 14 is interchangeable, which allows the speed of the cam 10 to vary and thereby change the number of blows of the chip breaker around the workpiece in a unit of time. and the device operates as follows. The device is mounted on the lateral support of the lathe so that the notched tool is located against the cutter, but on the opposite side of the workpiece. The actuator 15 starts, and the cam 10 starts to rotate. The tool 1 together with the holder 2 and the slider 3 moves away from the surface parts until the roller 9 slips off the ledge 19. Under the influence of the compressed spring 5, the slider 3 together with the holder 2 and the notched tool 1 begins to move rapidly in direction ii workpiece until the tool 1 is not yet udarits in its surface at the point at which turning parts by an angle of 180 under the influence of the cutter is converted into chips. When striking a workpiece, a notched tool makes a notch on its surface, which is 10 15 4 with the place where the chips break, cut with a cutter as the part rotates. After hitting the surface of the workpiece, the notched tool is carried along by the part in the direction of its rotation. At this time, the holder 2 rotates around the axis 17 until the cam 10, with its further rotation, starts again moving the slider 3 together with the holder 2 away from the part. When the slider 3 is moving away from the part, the notch tool 1 together with the holder 2 under the influence of the spring k again returns to its original position. Using the k axis to rotate the holder 2 and the spring k to return the holder 2 to its original position avoids the tool 1 breaking from rotating the workpiece at its moment of impact into its surface. Using interchangeable gears 14, an adjusting screw 6, cams 10 of a different profile allows to select the optimal number and force of the strikes of the cutting tool 1 to the surface of the workpiece. The application of the proposed device makes it possible to control the process of splitting chips while turning massive parts, simplify the design of the tool and increase its reliability. . Claims A chip crushing device for turning massive parts, comprising a caliper, a slider with a notch tool, mounted for movement in guides of the body fixed to the caliper, and a drive for moving the slider, in order to simplify the design, the notched tool installed in a slider with the possibility of swinging on an axis parallel to the axis of rotation of the workpiece; the slider is mounted so that it can move in the direction perpendicular to the axis of rotation of the workpiece and the spring n relative to the body in the same direction, and the drive movement of the slide is made in the form of a shock cam mechanism.
