Abstract
The utility model discloses a shell boring tool for a short stress rolling mill, which comprises a clamp body and a shell workpiece, wherein a plurality of groups of threaded holes are annularly arranged in the clamp body; one side of the clamp body is provided with a positioning pin hole; the clamp body is shaped like a disk. The utility model discloses owing to adopted the anchor clamps body up end to have the casing work piece through bolt-up, be provided with the locating pin between the anchor clamps body and the casing work piece, so, effectively solved the hole of casing processing among the prior art because positioning accuracy is not enough to cause the relatively poor technical problem of precision of bore hole, and then improved the bore hole precision of casing work piece.
Description
Technical Field
The utility model relates to a rod steel rolling technical field especially relates to a short stress is casing bore hole frock for rolling mill.
Background
In the prior art, the boring processing of the short stress rolling mill shell is usually carried out by matching a clamp.
However, in the process of implementing the technical solution of the present invention in the embodiment of the present application, the inventor of the present application finds that the above-mentioned technology has at least the following technical problems:
the hole machined by the shell has poor boring precision due to insufficient positioning precision.
SUMMERY OF THE UTILITY MODEL
The embodiment of the application provides a shell boring tool for a short stress rolling mill, solves the technical problem that holes machined in a shell in the prior art are poor in precision due to insufficient positioning precision, and improves the boring precision of shell workpieces.
The embodiment of the application provides a short stress is casing bore hole frock for rolling mill, including the anchor clamps body and casing work piece, its characterized in that: a plurality of groups of threaded holes are annularly arranged in the clamp body;
furthermore, one side of the clamp body is provided with a positioning pin hole.
Further, the clamp body is shaped like a disk.
Furthermore, the shell workpiece is provided with a through hole corresponding to the threaded hole.
Furthermore, the shell workpiece is provided with a through hole corresponding to the positioning pin hole.
Furthermore, a shell workpiece is fastened on the upper end face of the clamp body through bolts.
Furthermore, a positioning pin is arranged between the clamp body and the shell workpiece.
Furthermore, a straight surface is processed on one side of the clamp body.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
