Detailed Description

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 5, lathe include the lathe with not shutting down width stop device, be equipped with cutting off cutter 2 on the lathe, be equipped with bottom plate 3 on cutting off cutter 2's the knife rest, work piece 1 dress card is on lathe chuck, it has adjustable bolt 4 to articulate on bottom plate 3, adjustable bolt 4's one end is passed through opening separation blade 6 and nut 5 dress card on bottom plate 3, adjustable bolt 4's the other end is connected with the one end of removing support 7, the other end of removing support 7 is connected with spacing piece 9's one end through spacing screw 8, spacing piece 9's the other end supports with work piece 1's radial surface and leans on, spacing screw 8 passes through the packing ring, spring pad and M8 nut will remove support 7 and spacing piece 9 and fix.

Further: one side of the upper end face of the bottom plate 3 is provided with an ear plate 10, an adjustable bolt 4 of the ear plate 10 is clamped on the ear plate 10 through an opening blocking piece 6 and a nut 5, the other side of the upper end face of the bottom plate 3 is provided with a mounting hole 11, and the bottom plate 3 is fixed on a knife rest through the mounting hole 11 and a bolt.

Further: the side wall of the limiting sheet 9 is provided with a contact 12, and the contact 12 is abutted against the radial surface of the workpiece 1.

Further: adjustable bolt 4 is equipped with direction section 13, separation blade groove 14, screw thread section 15 and handle 16 from left to right in proper order, removes support 7 and direction section 13 threaded connection, and removes the lateral wall of support 7 and the laminating of the up end of bottom plate 3, and opening separation blade 6 is installed in separation blade groove 14, and nut 5 revolves soon to twist on screw thread section 15, through opening separation blade 6 and nut 5 with adjustable bolt 4 clamping on otic placode 10, otic placode 10 is located between opening separation blade 6 and the nut 5.

The working principle is as follows: clamping a workpiece 1 on a chuck of a machine tool, screwing a handle 16, driving a movable support 7 to move towards a cutting knife 2 by the rotation of a guide section 13 (because the support 7 is in threaded connection with the guide section 13, the side wall of the support 7 is in fit with the upper end surface of a bottom plate 3, so that the adjustable bolt 4 can move leftwards and rightwards and is similar to the relation between a screw rod and a screw nut) because the adjustable bolt 4 and an ear plate 10 are actually in a shaft-sleeve relation, then adjusting the distance between the cutting knife 2 and a contact 12 on a limiting piece 9 to the thickness of the required workpiece, moving the knife rest after determining the distance, enabling the contact 12 to be in contact with the radial surface of the workpiece 1, determining the position of the cutting knife, rotating the limiting piece 9 (through screwing the limiting screw 8, the limiting piece 9 can be rotated), enabling the limiting piece 9 to be far away from the workpiece 1, starting the machine tool, and cutting by using the cutting, after the first cutting is finished, the tool rest is continuously moved, the limiting piece 9 is adjusted to the initial position, the contact 12 is made to contact with the radial surface of the workpiece 1 again, the position of the cutting-off tool is determined again, then the limiting piece 9 is rotated again, the cutting-off tool is used for cutting off a second workpiece, and the steps are repeated in this way, so that the required workpiece can be continuously processed without stopping.

This embodiment is only illustrative of the patent and does not limit the scope of protection thereof, and those skilled in the art can make modifications to its part without departing from the spirit of the patent.
