Automatic tool changing mechanism matched with drilling and tapping integrated machine

Abstract

The invention relates to an automatic tool changing mechanism matched with a drilling and tapping integrated machine. The automatic tool changing mechanism comprises a rack, a lifting motion driving part, a spindle box, a machining tool, a tool magazine and a tool matching device. The spindle box comprises a box body, a main power part and a spindle, and the spindle is driven by the driving forceof the main power part to drive the machining tool to perform the drilling or tapping process. The tool magazine is supported by the rack and aligned with the spindle box, and the tool magazine comprises a base, a rotating disc, tool clamping arms and an auxiliary power part. The tool matching device comprises a linear motion element and a hooking piece. Each tool clamping arm comprises a tool armbody part, a hinging part, a pulling and lifting part and a tool clamping part, wherein the hinging part and the tool clamping part are formed by extending the tool arm body part oppositely in the length direction, and the pulling and lifting part is formed by extending the inner side wall of the tool arm body part inwards. After the pulling and lifting parts are aligned relative to the hooking piece, the linear motion element acts, and the tool clamping parts swing towards the spindle under the action of pulling and lifting force.

Description

technical field [0001] The invention relates to the technical field of manufacturing an integrated drilling and tapping machine, in particular to an automatic tool changing mechanism adapted to the integrated drilling and tapping machine. Background technique [0002] The integrated drilling and tapping machine integrates the functions of drilling and tapping at the same time. By replacing the processing tool on the spindle at the same station, the hole forming and subsequent tapping operations can be completed in sequence. When the processing process is switched There is no need for secondary tool setting, so it has higher processing efficiency, and the final forming quality of the threaded hole is better. [0003] At present, some models of all-in-one drilling and tapping machines on the market are equipped with tool magazines. The tool magazine is inclined at a certain angle relative to the horizontal plane, and is installed and arranged corresponding to the main shaft. ...

Problems solved by technology

The manipulator is not only complicated to control, inconvenient to maintain, but also expensive

However, some low-degree-of-freedom manipulators not only have low positioning accuracy and repeat positioning accuracy, but some manipulators that change tools from the side are prone to collisions with the machine tool spindle and tool magazine, and the clamping effect of the clamping mechanism is poor.
