Disc type high-capacity servo tool magazine

Abstract

The invention relates to a disc type high-capacity servo tool magazine. The disc type high-capacity servo tool magazine comprises a servo motor, a speed reducer, a bearing pedestal, a tool disc, a tool magazine cover and a tool magazine support. An output shaft of the servo motor is connected with the input end of the speed reducer. The output end of the speed reducer is concentrically connected with an inner hole in a flange shaft in a matched manner. The flange shaft penetrates the bearing pedestal to be fixedly connected with the tool disc. The bearing pedestal is fixedly connected with the tool magazine support. One end of the bearing pedestal is connected with the speed reducer through a flange plate. Two disc bearings are mounted in the bearing pedestal. A tool magazine cap is mounted on the outer portion of the tool disc. The tool magazine cover is fixed to the tool magazine cap through a rotary air cylinder. 24 tool forks are evenly distributed on the peripheral surface of the tool disc. The mounting faces of the tool forks are parallel to the rotary center line of the tool disc. The tool magazine is high in capacity, fast and accurate in locating, compact in structure and small in occupied space, transmission is stable and free of impacts, the use requirement generated when the requirement for the number of tools is high can be met, and the tool magazine can be mounted on a numerical control machine tool conveniently.

Description

technical field [0001] The invention relates to an accessory component of a numerically controlled machine tool, in particular to a disc-type large-capacity servo tool magazine. Background technique [0002] At present, the common automatic tool change magazine for CNC machine tools can accommodate 8 or 12 knives, the driving method adopts the intermittent transmission mechanism of the grooved wheel, and the mounting surface of the knife and fork is perpendicular to the rotation center line of the cutter head. Because this structure is an intermittent transmission mode, it often produces a large impact when the meshing enters and exits, and the positioning accuracy during transmission is low, which often causes a large reverse rotation gap in the cutter head. When more than 12 knives are required in the use of CNC machine tools, due to the limited capacity of the tool magazine, the use requirements are often not met. There are also some large-capacity tool magazines on the ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of the existing tool magazine such as small capacity of tool handle, large impact of transmission mechanism, low precision, complex structure, high cost and inconvenient installation, the purpose of the present invention is to provide a disc-type large-capacity servo tool magazine, which The capacity of tool holders in the tool magazine reaches 24 pieces. It adopts the driving method of servo motor and reducer. The disc-shaped cutter head is installed parallel to the rotation center line of the cutter head. The capacity of the tool holder is large, the transmission is stable, and the positioning accuracy is high. Easy to install on CNC machine tools
