Abstract

The invention discloses a machining center with a multi-tool-bit quick tool-replacement mechanism. The machining center comprises a rack, a working table and a machining tool, the machining tool comprises tool bits and a first power device driving the tool bits to rotate, and the machining center further comprises a tool magazine, a third power device, a fourth power device and a broach device; the tool magazine is located on the side of the working table to allow the broach device to provide tool-replacement tool bits, the tool magazine comprises a cutterhead with a plurality of tool rests, the tool bits clamped on the tool rests, and a second power device driving the cutterhead to rotate forwards and reversely to enable one of the vacant tool rests or the replaced tool bit to directly face the broach device; the third power device is used for driving the broach device to quickly move in the horizontal direction to get close to or away from the tool magazine; and the fourth power device is used for driving the broach device to quickly move in the vertical direction to get close to or away from the tool magazine. Compared with the prior art, in the tool-replacement step, the working step of the tool magazine is omitted, the redundant upward-moving step is avoided after tool replacement, and thus the tool-replacement efficiency of the whole machining center is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of machining centers, in particular to a machining center with a multi-cutter head quick tool change mechanism. Background technique [0002] The machining center is a machine tool used for CNC machining. It is a highly automated mechanical processing equipment. Its working feature is that it has a tool magazine, which can complete the automatic tool change work. , The machining center can automatically select the processing method, change the tool, automatically set the tool, automatically change the spindle speed, feed rate, etc., and can continuously complete a variety of processes, reducing the time for auxiliary processes such as workpiece clamping, measurement and machine tool adjustment. [0003] However, the existing automatic tool change method uses left and right lateral movement, and then rotates to change the tool. For example, the Chinese invention patent with the authorized announcement number ...
