Tool magazine changer for machining centers

Abstract

Disclosed is a tool magazine exchange device for a machining center. The tool magazine exchange device comprises a driving box and an oil cylinder telescopic shaft. The oil cylinder telescopic shaft extends from the inside of the driving box to the outside and conducts telescopic operation. The free end of the oil cylinder telescopic shaft is provided with a tool clamping rod assembly, thus driving is conducted through hydraulic oil, and outward extending and retraction of the oil cylinder telescopic shaft and even the tool clamping rod assembly are achieved. A driving assembly driving the oil cylinder telescopic shaft to rotate is arranged in the driving box. The tool clamping rod assembly comprises a first tool clamping rod and a second tool clamping rod which are designed in 180-degree symmetry. The first tool clamping rod and the second tool clamping rod each comprise a rod body, a cover body and a clamping jaw. Therefore, the tool magazine exchange device is compact in structure, convenient to assemble and disassemble, reliable in tool clamping, long in service life and large in bearing capacity, and the rigidity of a tool magazine is good.

Description

technical field [0001] The invention relates to the technical field of machine tool magazines, in particular to a tool magazine exchanging device for a machining center. Background technique [0002] Nowadays, the CNC machine tool industry has developed to the present, and its main structure and performance have become increasingly mature. There are more and more machining centers with a spindle speed of more than 30,000 rpm. The development of the tool magazine also has a relatively fixed model, and there are various types of tool magazines suitable for different needs. Among various tool magazines such as arm type tool magazine, single-disc tool magazine, bucket hat type tool magazine, chain tool magazine, etc., the structure of the knife arm magazine is relatively simple, and the price is low, which is very suitable for the tool magazine whose capacity is not too high. Suitable for large and small machining centers. [0003] In the past, the size of the tool magazine h...

Problems solved by technology

Under the long-term high-speed operation of the CNC machine tool, the positioning accuracy between the tool holder and the cutter head is prone to change, and the hook part of the tool changer is prone to heat and deformation, resulting in a decrease in the overall accuracy of the arm-type tool magazine, and the machining accuracy of the parts. Failure to meet the requirements, thus affecting the quality and reliability of processing
