Abstract

The invention provides a small lathe rapid transposition tool rest device which comprises a base and a clamping structure, a square tool rest body is rotatably arranged at one side of the base in a matched manner, an axial feeding structure and a radial feeding structure are arranged at the other side of the base, and a rotary positioning structure is arranged on a square tool rest. The rotary positioning structure comprises 45-degree direction transposition and 90-degree direction transposition. The tool rest device is simple in structure and reasonable in design, rough positioning is conducted through steel balls and springs, a handle is used for rotating a pressing spring, the elastic force of the springs can also press positioning steel balls and pins, then fine positioning is conducted, the structure of positioning pins, the steel balls, limiting pins and a cam is used for achieving transposition and positioning of the tool rest in the 45-degree direction, and then positioning canbe achieved. One tool is positioned on the tool rest in different directions, the machining functions of two tools can be completed.

Description

technical field [0001] The invention mainly relates to the technical field of small lathes, in particular to a quick indexing tool holder device for small lathes. Background technique [0002] At present, the tool holders of ordinary lathes at home and abroad still use the traditional square tool holders. Taking the taper pin positioning tool holder as an example, it can only be rotated at 90 degrees, and a tool is clamped. For different processes, tool replacement is required. Problems such as low processing efficiency. Contents of the invention [0003] 1. The technical problem to be solved by the invention [0004] The present invention provides a quick indexing tool holder device for a small lathe, which is used to solve the problem that the existing square tool holder mentioned in the above background technology can only be rotated at 90 degrees, and a tool needs to be clamped for different processes. The technical problem of tool change operation and low processing...
