Abstract

The invention relates to metal cutting processing and can be used in the processing of pipe ends used in shipbuilding, power and chemical engineering. The aim of the invention is to increase productivity by reducing the inertial forces arising from the reciprocating movement of the headstock, and reducing the changeover time of the machine. When the faceplate 3 is rotated, the copier 12 and the plate 16 rotate at the same speed. Due to the inclination of the axis of rotation of the plate 16, sector 11 performs for each revolution of the faceplate 3 reciprocating movements, as a result of which the width of the ribbon chamfer is the same around the entire perimeter. When the caliper 4 is radially moved to the center, the copier finger 13 and the slider 15 move at the same rate, thereby ensuring a corresponding decrease in the reciprocating movement of sector 11, which ensures chamfering at the beveled ends of sectors of different diameters with optimal cutting conditions and high chamfer accuracy. 2 Il.

Description

moving the headstock, and reducing the time | machine changeover. During the rotation of the faceplate 3, the copier 12 and the plate 16 rotate at the same speed. Due to the inclination of the axis of rotation of the plate 16, Hector 11 performs for each revolution of faceplate 3 reciprocating movements, resulting in the width of the chamfer with the same lepHMeTpy. With radial movement

caliper 4 to the center with the same speed move the finger 13 and the slider 15, which ensures a corresponding decrease in the magnitude of the reciprocating movement of the sector 11, which provides machining, chamfer on the beveled ends of the sectors of different diameter with optimal cutting conditions and high chamfer accuracy . 2 Il.

The invention relates to metal cutting and can be used in the processing of pipe ends used in shipbuilding, energy and chemical engineering.

The aim of the invention is to increase productivity by reducing the inertial forces arising from the reciprocating movement of the headstock, and reducing the machine overvoltage time.

FIG. 1 shows a machine, a general view5 of FIG. 2 a - a copier and faceplate with a plansupport.

The machine consists of a bed 1, a movable headstock 2, carrying a faceplate 3 p with a caliper 4. Inside the headstock 2, there are mechanisms for rotating the faceplate 3s of the working feed of the caliper 4 and the movement of the headstock 2. In a clamping device 5 mounted on the frame 1, a copier 3 is fixed coaxially to the axis of rotation of the faceplate 3. I The coping device 6 consists of the hull 7, the clamp 8 with the cams E, 10, with which the abatable sector 11 is fastened with the bevelled wrestler a. Inside the housing 7, there is a fiH copier 12 with a copier finger 13, | which through a hinge 14 is connected to floor 15, is located on the plate 16. Copier 12 is connected to faceplate 3 by a telecom (copy shaft 17 and shaft 18, which is attached to the faceplate 3 with a screw | 9. The copy finger 13 kinematically ||; it is engaged with the caliper 4 through gear-pinion gears 20-23 and the telescope-41вский shaft 24. In the caliper 4, the cutter 25 is fixed, while its cutting edge is coaxial with the axis of rotation the copier fell 13 and the hinge 14.

the slider 15 and the plate 16 intersect at one point b. The plate 16 is mounted on the housing 26, which bears a worm gear 27, which engages with the screw 28. The screw of the wheel 27, 28 rotates the plate 16 with the slider 15 around the point b by the angle J, equal to the angle of the bevel of the sector 1 b

The chamfering at the beveled end of sector 11 is carried out in the following manner.

The clamping device 5 is mounted coaxially with the faceplate 3 and the copier 6 is fixed. With clamping 8, the cams 9 and 10 clamp the sector 11 with the end of the q obliquely angled oi. Shaft 18 is mounted on faceplate 3 and secured with screw 19. In support 4, cutter 25 is fixed so that its cutting edge is coaxial with the axis of rotation of copier pin 13 and hinge 14. At this position, rail 22 is rigidly fixed to support 4. By moving stockhead 2 telescopic shafts 17, 18 and 24 are connected. By rotating the worm 28, the housing 26 through the worm gear 27 rotates around point b at an angle f equal to the angle of the bevel of the end of the cx sector 11, but not more than 15. Such a feed of the caliper 4 and the headstock 2 is set so that the resulting movement of the cutter 25 along the generatrix is carried out at an angle equal to the minimum angle of the chamfer. The required depth of cut is set and the drive for rotating the faceplate 3 (not shown) is activated.

When the faceplate 3 is installed, the copier 12 and the plate 16 rotate at the same frequency. By tilting the axis of rotation
