The spindle of the machining center does not stop rotating, and there is an automatic tool changer for manipulators

Abstract

The invention belongs to the field of numerical control machining devices and specifically relates to an automatic tool changer (ATC) with a manipulator and an incessantly rotating spindle for a machining center. The ATC comprises the spindle, tool handles, a tool magazine, the tool changing manipulator and a numerical control system. The spindle has the functions of speed governing and circumferential position real-time detection and adjusting. Each tool handle comprises an outer conical handle body coaxially connected with the spindle, a tool body, a bearing arranged on the tool body in a sleeving mode, a groove, a meshing device A and a tool. The tool magazine comprises a plurality of tool positions and a tool position changing device. Each tool position comprises a conical sleeve used for clamping the corresponding tool, tool driving motors, a tool circumferential position real-time detection and adjusting system, and a meshing device B meshing with the corresponding tool. The tool driving motors drive the tools to rotate. Through the ATC, fast tool changing can be achieved between a tool on the spindle of the machining center and the tools in the tool magazine under the circumstance that the spindle rotates incessantly, so that the auxiliary machining time during machining of the machining center is saved, the service efficiency of a numerically-controlled machine tool is improved, the machining cost is reduced, and the application prospects are wide.

Description

technical field [0001] The invention belongs to the field of numerical control machining devices, in particular to a fast automatic tool changing device for a spindle of a numerical control machining center without stopping rotation. Background technique [0002] The development and application of electric spindles, high-speed lead screws and linear motors have greatly improved cutting efficiency. In order to match the high efficiency of machine tools, the high-speed automatic tool changer (ATC), one of the important components of machining centers, has also become a high-speed machining tool. Important technical content of the center. With the improvement of cutting speed and the continuous shortening of cutting time, the requirements for tool change time are also gradually increasing. The speed of tool change has become an important indicator of high-level machining centers. [0003] There are three main methods to measure tool change speed: 1. Tool-to-tool tool change ti...

Problems solved by technology

The tool change of the machine tool is usually carried out after the spindle stops rotating, but it takes a certain amount of time from the stop of the machine tool spindle to the restart to reach the rated speed, which is actually a waste of time. The auxiliary time required for the rated speed, the present invention provides an automatic tool changer with a manipulator for the spindle of the machining center that does not stop rotating, aiming at reducing the auxiliary time for processing and improving the utilization rate of the machine tool
