Rotating and staggering type broach mechanism of turning and milling tool rest

Abstract

The invention discloses a rotating and staggering type broach mechanism of a turning and milling tool rest, and belongs to the technical field of machine tool tool holders. The rotating and staggeringtype broach mechanism of the turning and milling tool rest comprises a ram, a turning and milling shaft steel sleeve, a clamping disc spring, a hydraulic loosening oil cylinder, a spline tensioning sleeve, a rotating and staggering mechanism, a tool holder transition body, a tool holder, a milling main shaft, a tool holder transition body end fluted disc and a tool holder end fluted disc, the turning and milling shaft steel sleeve is installed in the center of an inner cavity of the ram of the tool rest, the hydraulic loosening oil cylinder is installed on the upper portion of the turning andmilling shaft steel sleeve, the clamping disc spring is arranged below the hydraulic loosening oil cylinder, the hydraulic loosening oil cylinder is clamped on the spline tensioning sleeve, the upperportion of the spline tensioning sleeve is in linkage with the rotating and staggering mechanism through a spline, the rotating and staggering mechanism is fixed to the upper portion of the inner cavity of the ram, the tool holder transition body is connected to the lower portion of the inner cavity of the ram through bolts, the tool holder transition body end fluted disc and the tool holder endfluted disc are installed between the upper portion of the tool holder and the lower portion of the tool holder transition body, and the milling main shaft penetrates through a central cavity of the spline tensioning sleeve for matched connection. According to the rotating and staggering type broach mechanism of the turning and milling tool rest, the purpose of ram tool changing high-precision positioning is achieved, and the cutting effect is more ideal.

Description

technical field [0001] The invention relates to a rotary dislocation broaching mechanism of a turning and milling tool holder, which belongs to the technical field of machine tool holders. Background technique [0002] At present, the development trend of my country's machine tool products is developing in the direction of high efficiency and compounding. The vertical turning and milling machining centers are basically equipped with automatic broach changing function, and the broaching force and the cutting and torsion resistance of the tool holder reflect the important parameters of the cutting performance of the machine tool. The tool holder of the vertical turning and milling machining center generally adopts the joint positioning method of the tapered shank pull stud and the positioning key, but the tension force of the general specification pull stud is insufficient, and the positioning key of the tool holder has high requirements for the assembly process. The defects o...

The tool holder of the vertical turning and milling machining center generally adopts the joint positioning method of the tapered shank pull stud and the positioning key, but the tension force of the general specification pull stud is insufficient, and the positioning key of the tool holder has high requirements for the assembly process. The defects of these two points Limits the effect of tool change cutting on large-scale machine tools
