Embodiment 1

[0031] Such as figure 1 The shown automatic tool change system includes a tool change mechanism and a tool clamping mechanism; the tool change mechanism includes a rotor disk 7 arranged on the motor shaft 3, and an electromagnetic assembly is arranged on the rotor disk 7; the electronic shaft adopts a spline shaft , which can be better suited to the requirements of high-speed rotation during tool processing. The tool clamping mechanism includes a tool disc 10 for clamping tools, and the end surface of the tool disc 10 close to the rotor disc 7 is provided with an armature disc 8 that cooperates with the electromagnetic assembly; The holding mechanism is connected to the tool change mechanism or separated from the tool change mechanism.

[0032] When the electromagnetic component is powered on, it generates magnetic force to attract the armature disc 8, thereby attracting the tool disc 10 and connecting it with the rotor disc 7; when the electromagnetic component is powered of...

Embodiment 2

[0041]The tool change mechanism of the automatic tool change system is usually installed on the robot, and multiple tool disks with tools are installed on the tool holder. By controlling the movement of the robot and the tool change mechanism, the automatic change of the tool can be realized. The specific steps are as follows:

[0042] When it is necessary to change the tool during processing, the robot controls the movement of the tool change mechanism, so that the tool change mechanism can be accurately positioned on the vacancy on the tool holder where the tool disc can be placed, and the electromagnetic coil assembly is controlled to be powered off. Disengage from the tool changing mechanism, and place the tool disc 10 on the tool rest.

[0043] Then the tool changing mechanism is controlled to move to the corresponding position above the tool disc 10 to be replaced; the electromagnetic coil assembly is controlled to be energized, and the tool disc 10 is connected to the to...

Abstract

The invention discloses an automatic tool changing system and tool changing method. The automatic tool changing system comprises a tool changing mechanism and a tool clamping mechanism. The tool changing mechanism comprises a rotor disc arranged on a motor rotating shaft, and an electromagnetic assembly is arranged on the rotor disc. The tool clamping mechanism comprises a tool disc used for clamping a tool, and an armature disc cooperating with the electromagnetic assembly is arranged on the end face of the side, close to the rotor disc, of the tool disc. Through powering on and off of the electromagnetic assembly, the tool clamping mechanism can be connected to the tool changing mechanism or separated from the tool changing mechanism. The automation degree of the tool changing manner ishigh, the tool can be rapidly replaced, time can be effectively saved, and machining efficiency can be improved; and through bidirectional conic hole locating, the repeated locating precision after tool changing can be effectively guaranteed, and machining quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an automatic tool changing system and a tool changing method. Background technique [0002] During the engraving, grinding and deburring process of industrial robots, due to the requirements of the processing technology, the tool needs to be replaced frequently. If the tool is changed manually, the TCP coordinate system of the tool needs to be recalibrated every time the tool is changed, which wastes processing time and greatly reduces the processing time. efficiency. At this stage, the load capacity of commonly used industrial robots is mostly only tens of kilograms to more than one hundred kilograms, and the greater the load, the greater the impact on the motion performance of industrial robots, and the traditional tool changer for rotary tools is not suitable for industrial robots. . Contents of the invention [0003] The purpose of the present invention is t...
