A convenient tool changing device for the tool magazine of the gantry type machining center

Abstract

The invention discloses a convenient tool changing device for a tool magazine of a gantry type machining center, specifically relates to the field of a tool changing device for a tool magazine, including a No. The No. linear guide rail drives the spindle equipment to approach and stay away from the disc-type tool magazine, and the tool magazine drives the motor to drive the disc-type tool magazine to rotate; No. 2 linear guide. In the present invention, a cleaning assembly is arranged on the outside of each cutter slot, the No. 1 servo motor drives the driving sprocket to rotate, the driving sprocket drives the chain to rotate, the chain can simultaneously drive multiple driven sprockets, and then the driven sprocket drives the top The gear rotates, and the gear meshes with the rack, which can drive the C-shaped ring plate to rotate, that is, the cleaning pad rotates to clean the cutting fluid and debris on the outer wall of the bottom of the tool, which is conducive to tool maintenance and does not affect the next use.

Description

technical field [0001] The invention relates to the field of tool changing devices for a tool magazine, in particular to a convenient tool changing device for a tool magazine of a gantry type machining center. Background technique [0002] The gantry machining center refers to the machining center in which the axis of the spindle is perpendicular to the workbench. The overall structure is a portal frame, which is composed of double columns and top beams, and there is a beam in the middle. Especially suitable for processing large workpieces and workpieces with complex shapes. [0003] Most of the CNC gantry machining centers in the prior art are equipped with a disc-type tool magazine, and use the rotation of the disc and the horizontal and vertical drive structure of the main shaft to realize the left and right, up and down movement of the tool changer. [0004] However, when this kind of disc-type tool magazine cooperates with the CNC gantry machining center for tool chang...

AI Technical Summary

Problems solved by technology

[0004] However, when this kind of disc-type tool magazine cooperates with the CNC gantry machining center for tool change, cutting fluid and debris will remain on the replaced tool and the mounting plate above the tool, because each fixture on the disc will contact each other. Contamination of fixtures, discs and even adjacent tools is not conducive to the maintenance and use of tools, discs and the entire tool magazine, and also affects the user experience. The existence of cutting fluid and debris for a long time may also affect the accuracy of tool magazine rotation and feeding, etc.
