Vertical disc type tool changer

Abstract

A vertical disc tool magazine, comprising a revolving body and tool holder units distributed on the surface of the revolving body, the revolving body includes an annular tool holder and a rotating shaft located in the middle of the annular tool holder, on the rotating shaft A number of induction lamps A are provided, a counter is provided outside the rotary shaft, and an induction lamp B is provided on the counter, the ring tool rest and the rotary shaft are connected by several supporting ribs, and the rotary shaft is decelerated The machine is connected with the servo motor, and the annular tool rest is evenly distributed with several through holes in the axial direction. The tool holder units are respectively arranged in the through holes, and the back of the annular tool rest is provided with hole to prevent the tool from falling off; this type of vertical disc tool magazine not only ensures the rigidity of its movement, but also reduces the manufacturing cost and improves the control accuracy. It can easily record the number of times the tool is used, so as to facilitate timely Trimming and maintenance, simple and practical, easy to operate.

Description

technical field [0001] The invention relates to a tool magazine, in particular to a vertical disc tool magazine, which belongs to the field of CNC machine tool manufacturing. Background technique [0002] As a representative of CNC machine tools in the new era, high-speed machining centers have been widely used in the field of machine tools. Its high-speed, high-efficiency, high-precision and other characteristics have won the favor of the market. To obtain a machining center with high-speed, high-efficiency, and high-precision characteristics, the quality of its disc-type tool magazine has become the constraint of the above characteristics. The tools assembled by the disc-type tool magazine More, plus the mass of the main body, resulting in slow startup acceleration and long stop delay, which affects the high-precision operation of the high-speed machining center. [0003] The clamping force of the tool holder used to clamp the tool in the disc tool magazine is also the ke...

Its high-speed, high-efficiency, high-precision and other characteristics have won the favor of the market. To obtain a machining center with high-speed, high-efficiency, and high-precision characteristics, the quality of its disc-type tool magazine has become the constraint of the above characteristics. The tools assembled by the disc-type tool magazine More, plus the mass of the main body, resulting in slow startup acceleration and long stop delay, which affects the high-precision operation of the high-speed machining center

[0003] The clamping force of the tool holder used to clamp the tool in the disc tool magazine is also the key to the design. When the clamping force is too large to change the tool, the tool changing manipulator has a large bearing capacity, and the friction force on the tool handle is also large, and the jaws wear too quickly , if the clamping force is too small, it will cause insufficient clamping force, resulting in tool drop phenomenon, prone to severe tool wear, forgetting to replace it, and not knowing the number of times the tool is used during work, which is very inconvenient
