Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] see figure 1 , the existing turret type tool post mainly includes a driving shaft 101, on which a rotating tower 102 is fixedly connected, on which the rotating tower 102 is fixedly installed with multi-group grouping cutter heads 103, and each group is divided into groups Cutter head 103 all comprises cutter and sub-shaft, and when in use, drive shaft 101 drives rotating tower 102 to rotate, and the grouping cutter head 103 that will use is transferred...

Abstract

The invention relates to a turret type tool rest reducing rigidity requirement for a main shaft. The tool rest comprises a fixed tower, wherein a support piece is fixedly installed in the front of thefixed tower, a spindle is rotationally connected in the support piece, a tool rest rotating table is rotationally connected to the front of the fixed tower, and a plurality of tool bit assemblies aremovably inserted in the tool rest rotating table. According to the turret type tool rest reducing rigidity requirement for the main shaft, a tool magazine is designed in a rotating ring shape, tool bits are installed on the tool rest rotating table, and different tool bits can be automatically installed on the main shaft by rotating the rotating table. The tool rest is only provided with one mainshaft and no auxiliary shafts, so that the rigidity requirement for the main shaft is reduced, structures such as a plurality of auxiliary shafts, auxiliary shaft driving motors, corresponding accessories and connecting wires are omitted, failure structure points are reduced, the manipulator structure necessary for tool change is omitted, occupied space is reduced, and the turret type tool rest is more suitable for small numerical control centers.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a turret-type tool holder which reduces the rigidity requirement of a spindle. Background technique [0002] The function of the CNC machine tool magazine is to reserve a certain amount of tools, and realize the exchange with the tools on the spindle through manipulators and other methods. Among them, the turret tool magazine is generally only used in small CNC machining centers due to the small number of loaded cutter heads. , The turret-type tool magazine has the advantages of compact structure and short tool change time. By rotating the turret, the sub-spindles of each tool head rotate to the processing position in turn according to the program instructions, thereby realizing automatic tool change. This tool change method , since the sub-spindles of each cutter head are concentrated on one turret, the rigidity requirements for the turret spindle are rel...
