Tool magazine changer for horizontal machining centers

Abstract

The invention discloses a tool magazine exchange device for a horizontal machining centre. The tool magazine exchange device is applied to the horizontal machining centre and comprises a driving box and a center shaft, wherein the center shaft extends out from the driving box; a tool clamping bar assembly is arranged at the free end of the center shaft; a driving assembly driving the center shaft to rotate is arranged inside the driving box; the tool clamping bar assembly comprises a first tool clamping bar and a second tool clamping bar, wherein the first tool clamping bar and the second tool clamping bar are symmetrically arranged at 180 degrees; the driving assembly comprises a servo motor, a driving gear, a first driven gear and a transmission gear assembly; and each of the first tool clamping bar and the second tool clamping bar comprises a bar body, a cover body and a clamping jaw. The tool magazine exchange device is simple in structure, small in size and convenient to install; through the cooperative motion of a connecting rod mechanism, fast entering and exiting of tool bars can be realized, and tools can be stably located; and transmission is more accurate, and operation is more stable.

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 horizontal 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...

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
