Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in the figure, the damping machining tool for the conical shell inner wall vertical lathe comprises

The device comprises a chassis 1, wherein 8 main T-shaped grooves 11 are arrayed on the upper end surface of the chassis 1 along the circumference of the chassis 1, and two sides of each main T-shaped groove 11 are respectively provided with 1 auxiliary T-shaped groove 12 parallel to the main T-shaped groove; 4 hexagonal countersunk holes 13 are linearly arrayed along the radial direction between two adjacent main T-shaped grooves 11 on the lower end surface of the chassis 1;

the 8 supporting legs 2 comprise a bottom plate 21, an inner side plate 22 fixedly connected with the bottom plate 21, fitting the outline of the conical shell workpiece 100 and abutting against the conical shell workpiece 100, an outer supporting plate 23 fixedly connected with the bottom plate 21 and the inner side plate 22, a T-shaped sliding block 24 matched with the T-shaped groove 11 is fixedly connected at the lower end of the bottom plate 21, and a horizontal through groove 25 is formed in the bottom plate 21; the supporting legs 2 are provided with a plurality of through holes so as to facilitate hoisting or temporarily penetrate through the hexagon screws 4 to prevent loss.

The middle parts of the 16 pressing plates 3 are provided with through holes, one ends of the 8 pressing plates 3 are pressed on the outer edge 101 of the lower end of the conical shell workpiece 100, and one ends of the 8 pressing plates 3 are pressed on the horizontal through grooves 25 of the supporting legs 2;

the nail heads of 16 hexagon screws 4 and 8 hexagon screws 4 are inserted into the auxiliary T-shaped groove 12, the nail heads of 8 hexagon screws 4 are sunk into 8 hexagon countersunk holes 13, and the screw rods of 16 hexagon screws 4 are screwed with nuts after penetrating through the through holes on the pressure plate 3;

and 16 cushion blocks 5 respectively arranged at the non-pressing ends of the pressing plate 3.

One end of each of the 8 pressing plates 3 is pressed on the outer edge 101 of the lower end of the conical shell workpiece 100 to axially position the conical shell workpiece 100, and the 8 supporting legs 2 are used for circumferentially positioning the conical shell workpiece 100, so that the vertical lathe can conveniently process the conical shell workpiece.
