Top following tool magazine tool changing device and method thereof

Abstract

The invention relates to a top following tool magazine tool changing device and a method. The top following tool magazine tool changing device comprises a barrel-shaped chain unit and a servo motor. A drive gear and a driven gear which are engaged with the barrel-shaped chain unit are arranged at the left end and the right end of the inner side of the barrel-shaped chain unit respectively. The drive gear is installed on an output shaft of the servo motor. The driven gear is installed on a driven shaft. A tool guiding sleeve is clamped on the outer side of the barrel-shaped chain unit through a tool guiding sleeve clamping groove. The tool guiding sleeve is provided with a tool. The tool guiding sleeve and the tool can transmit along with a chain of the barrel-shaped chain unit. A cam tool changing mechanism is arranged below the right side of the barrel-shaped chain unit. A hydraulic cylinder is in drive connection with the cam tool changing mechanism. A rotary tool changing mechanism is arranged beside the cam tool changing mechanism. A tool magazine and the tool changing device are installed on the top of a stand column, the transverse size of a machine tool is more compact, and the occupied area of the machine tool is reduced. The form that the tool magazine and a tool changing mechanical arm move along with the stand column is adopted, and a main shaft only needs to move to the Y-axis tool changing position during tool changing so as to reduce the tool changing path, shorten tool changing time and simplify the program.

Description

technical field [0001] The invention relates to a tool changing device and method for a top-mounted traveling tool magazine. Background technique [0002] At present, the tool magazine of most machine tools or machining centers is separated from the spindle of the machine tool. The position of the tool magazine is fixed. When changing the tool, the spindle needs to move to the installation position of the tool magazine. On the one hand, the separation of the tool magazine from the spindle increases the machine tool footprint; on the other hand, due to the distance between the spindle and the tool magazine, it takes a certain amount of time for the spindle to move to the tool change position in the tool magazine, and the programming is also cumbersome, which reduces production. Processing efficiency. [0003] Patent CN 101862978A discloses a tool magazine follow-up device, which can make the tool magazine move with the saddle (the main shaft is installed on the saddle), and ...

Problems solved by technology

However, the accompanying device of the tool magazine is separated from the main shaft, and the device is relatively heavy and needs to be installed on the sliding saddle, thus increasing the floor space of the machine tool. In addition, the device needs to be moved to the workpiece processing position when the tool is changed, and then the tool is changed.
