Impeller processing tooling for horizontal lathe

Abstract

The invention discloses an impeller processing tool for a horizontal lathe. The impeller processing tool comprises a base, a lantern ring and a cover plate. The base is of a disc-shaped structure. The lantern ring is of a circular ring structure. A boss matched with an inner hole of the lantern ring is disposed on the center of the base. A plurality of first connecting holes evenly distributed along the central line are arranged on the base and the cover plate. The first connecting holes are connected with first nuts through first screws. The height of the boss is larger than the height of the lantern ring. The inner hole of the lantern ring is in transition fit with the boss. An impeller can be mounted and demounted conveniently, positioning is reliable, and meanwhile processing precision is guaranteed. The base and the lantern ring are respectively provided with corresponding second connecting holes. The second connecting holes are connected with second nuts through second screws. The impeller processing tool is compact in structure, reasonable in stress, accurate in positioning and reliable in clamping and ensures processing quality. The lantern ring is light in weight and can be repeatedly used, and cost can be saved effectively.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an impeller processing tool for a horizontal lathe. Background technique [0002] In the prior art, the tooling structure used in the processing of the impeller on the horizontal lathe includes a base, a stepped plate, and a cover plate. The base is a disc-shaped structure, the base is fixed on the horizontal wheel disc through a pressure plate, and the stepped plate is a stepped disc-shaped structure. , According to the actual size of the inner hole of the impeller, the corresponding ladder can be equipped to match the inner hole of the impeller. The cover plate fixes the impeller on the stepped disk through a bolt. After a certain number of impellers are processed, the size of all the steps on the stepped disk becomes too small to match the inner hole of the impeller to be processed, and a new stepped disk is manufactured. . The problems with the base of this st...

AI Technical Summary

Problems solved by technology

The problems with the base of this structure are (1) After the whole set of tooling and the impeller are assembled, the center of gravity of the impeller is far away from the horizontal wheel disc, forming a relatively large moment, which may easily cause the position of the whole set of tooling to be unstable

(2) The cover plate fixes the impeller on the stepped disk through a bolt. Once the threaded connection becomes loose, it will affect the processing of the impeller
