Abstract

The invention relates to a quick manual tool changing mechanism of a numerical control milling machine, which comprises a tool holder. A cam is installed on the holder, a tool-changing handler is connected to the cam, a mandril is arranged on the lower part of the cam, a bolt connected to the end of the mandril around which springs are provided, a spindle is arranged on the lower part of the tool holder, a pull rod which is on the relative position to the spindle is sleeved inside the spindle, disk springs are provided around the upper end of the pull rod, the upper end of the pull rod is connected with the spindle by locknuts, a cutter fixed seat is connected to the end part of the pull rod, and a taper hole at the end of the spindle is led to the cutter fixed seat. The device greatly reduces the manufacturing and using cost, improves tool changing efficiency of manual changing mechanism simultaneously, and reduces working intensity of labors. The mechanism is not only characterized in high efficiency and low working intensity of a pneumatic tool changing mechanism, but also in simple structure and lower cost of the manual tool changing mechanism.

Description

technical field [0001] The invention relates to a tool changing mechanism, in particular to a fast manual tool changing mechanism for a numerically controlled milling machine. Background technique [0002] The CNC milling machine can complete the processing of milling, drilling, expanding, boring, reaming and tapping. Its processing efficiency is usually 3-4 times that of ordinary machine tools such as ordinary milling machines, ordinary boring machines, and ordinary drilling machines. The machining accuracy is much higher than ordinary machine tools. It is suitable for processing various discs, shells and box parts, and is suitable for medium and small batches and multi-variety production. Therefore, it is widely used in production, maintenance and teaching. Especially in foreign countries, it is more widely used in teaching and family. At present, the tool change mechanism of economical CNC milling machines usually adopts two methods: one is to use the pneumatic tool c...
