Main shaft take-out type tool changing device

Abstract

The invention provides a main shaft take-out type tool changing device comprising a tool changing mechanism and a tool rest. The tool changing mechanism comprises a driving mechanism, a cutter head and a main shaft; the tool rest is arranged on the cutter head; the driving mechanism is respectively connected with the cutter head and the main shaft; the main shaft drives the tool rest to move up and down under the action of the driving mechanism so as to realize take-out and return of the tool rest, and can drive a tool on the taken-out tool rest to rotate. According to the device, three-dimensional motion tool changing needed by a daily automatic knife changing system is reduced and replaced by two-dimensional plane motion, the mechanism cost is saved, and the mechanism reliability is improved. The main shaft take-out type tool changing device adapts to general automatic processing equipment suitable for vertical cutting motion of the tool.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a main shaft pull-out type tool changing device. Background technique [0002] Stone polishing is a very important process in the stone processing process. Almost all stones must be polished before they can be used as materials. In the past, stone polishing was done manually, but manual polishing was labor-intensive and the production environment was poor. With the increase of labor costs, machine automatic polishing has gradually replaced manual labor. The stone automatic polishing machine mainly polishes the surface of the stone through the high-speed rotation of the cutter. Due to the different positions of the stone and different grinding processes, different tools are often required to complete the process. Tool change is a non-processing process that is often required in the processing process. There are currently two ways to change the tool, one is...

Problems solved by technology

However, as far as the current automatic tool changer is concerned, the structure is relatively complicated and the tool change time is long. First, the manipulator is required to select the required tool from the tool magazine, and then the corresponding tool is clamped on the spindle, and finally the manipulator is withdrawn. The process of changing the tool is considered to be over

This type of tool changing system requires a large number of mechanism coordination to complete, which is not suitable for stone grinding, and the manufacturing cost of the whole set of cutterhead kinematics is expensive
