SU1211000A1 - Slotting head - Google Patents

Description

  one

 The invention relates to a mass-structure, in particular, to devices for processing holes and grooves of various profiles,

The purpose of the invention is to increase the rigidity of the head and expand technological capabilities by reducing friction between the elements of the head, increasing the cutting speed and the stroke of the cutter installation of the latter at an angle to the horizontal plane.

FIG. 1 shows a slotting head, a longitudinal section J in FIG. 2, the same, top view.

The slotting head consists of a body 1 in the form of a yoke, on which an axis 2 is installed. On the axis 2 there is a rocking body 3 of an intermediate element 4, made in the form of a slide. The slider 4 has a bearing 5. In the case 3 of the slider 4 there is an adjustable stop 6 and an elastic element 7 made of rubber, and a spring 8 is installed between the slider 4 and the case 3, Inside the case 1 there is a mandrel consisting of two cams 9 and 10, installed in the spindle 11 of the machine. The upper cam 9 of the mandrel contacts with the carrier 5 of the slide 4, and the lower cam 10 with the bearing 12 mounted on the double-arm lever 13, which is located on the axis 14 and contacts with the adjusting screw 15 with the housing 3 of the slider 4, the housing 1 is attached to the spindle grandma 16 machine with bolt 17,

The eccentric 18 serves to tilt the lever 13c to stop its contact with the cam 9,

The installation of the slotting head on the machine is as follows. In the machine spindle 11, a mandrel consisting of two cams 9 and 10 is installed. After that, turning the eccentric 18, which pushes the double-arm lever 13 to 90, the slotting head is set to the desired angle for operation, fixing its position on the headstock 16 with the bolt 17, then the lever 13

together with the bearing 12 returns to contact with the cam 9 by means of the eccentric 18, the slotter is ready for operation.

The operation of the slotting head is carried out as follows.

After turning on the machine, the mandrel, by rotating, with the help of cams 9 and 10, transfers the toolholder and reciprocating movement. The reciprocating movement is carried out due to the contacting of the cam 10 with the bearing 5 mounted on the slider 4, and the swinging movement takes place by the contact of the cam 9 with the bearing 12 mounted on the lever 13. Adjusting elements (screw 15 and the stop 6) serve for

setting the angle of the slider body in the horizontal plane of the machine table.
