Abstract

The invention relates to the field of machine tools, in particular, to machining parts on turning and grinding machines. The aim of the invention is to improve clamping reliability by using one drive to move two groups of cams. The clamp 13 acts on the membrane 5, and its cams 6 converge to the axis of rotation of the cartridge. At the same time, the pivoting lever 11 rotates clockwise on the axis 12 and by means of the axis 16 and the bracket 15 moves the slide 14 in the direction opposite to the movement of the membrane 5. At this, the cams 3 and 6 clamp the part along the outer and inner surfaces. 1 Il. sl 00 o 00 N ate

Description

The invention relates to a machine tool industry, in particular to machining parts on turning and grinding machines.

The purpose of the invention is to improve clamping reliability by using one drive to move two groups of cams.

The drawing shows a membrane cartridge, obsh, iy view.

The membrane cartridge works in the following way.

Before installing (removing) the parts 9, the drive rod 10 is moved along the axis in the direction of arrow A. In this case the adjustable clamp 13 acts on the membrane 5 and its cams 6 converge to the axis of the cartridge. At the same time, the pivoting lever 11 rotates on the axis 12 clockwise and, through the axis 16 and the bracket 15, the re-membrane cartridge consists of a housing 14 slider 14 in the direction opposite to 1, inside which the membrane 2 is rigidly fixed with the outer cams 3 and through the intermediate disk 4 the membrane 5 with cams 6. In the intermediate disk 4 there are openings for passing the cantilever cams 3. The cams 3 and 6 have adjustable screws 7 and 8 by means of which the part 9 is clamped. The cantilever cams 3 of the membrane 2 have adjustable clamping the elements by which the workpiece is clamped. In the cartridge, there is a drive consisting of a drive key 10 with a groove for passing the pivot arm 11 mounted in the housing 1 on the axis 12 and fixed to the end of the key of the adjustable clamp 13, half 15

positive arrow A, and acts on the membrane 2.

The cams 3 of the membrane 2 clamp the part 9 on the outer surface, and the clamping cams 6 of the membrane 5 - on the inside.
