Gantry numerical control milling machine

Abstract

The invention discloses a gantry numerical control milling machine. The gantry numerical control milling machine structurally comprises a sliding sleeve block, a supporting frame, a milling machine table, a fixing device, a movable groove, a sliding plate, a buckling block, a micro motor, a milling cutter head, an anti-collision cutter device, a sliding rail and a milling cutter. When the improvedgantry numerical control milling machine is used, the width of a limiting groove is adjusted through the cooperation of a protective spring and a traction rod, a to-be-machined workpiece is installedon a movable plate and fastened with the milling machine table through arc-shaped clamping blocks, so that the to-be-machined workpiece can be stably fixed to a machining position, air blowing treatment is conducted on gaps in the milling machine table through an air blowing head, and the cleanliness of the milling machine table is guaranteed. The milling cutter is installed in an anti-collisiontank, a lock catch and a clamping piece are matched to lock the milling cutter, a pull rod and a pull plate cooperates to pull the anti-collision tank, the milling cutter is pulled to a certain height, and the phenomenon that the milling cutter collides with the machined part is avoided. The milling cutter is protected using a buffer spring, the impact force generated when the pull rod pulls the milling cutter is reduced, and the production efficiency of the milling machine is improved.

Description

technical field [0001] The invention relates to the field of numerically controlled milling machines, in particular to a gantry numerically controlled milling machine. Background technique [0002] A milling machine is a machine tool that uses a milling cutter to mill a workpiece. It mainly refers to a machine tool that uses a milling cutter to process various surfaces on a workpiece. Usually, the rotation of the milling cutter is the main movement, and the movement of the workpiece and the milling cutter is the feed movement, which can be processed Planes and grooves can also process various curved surfaces and gears. The CNC milling machine is a machine tool that integrates a digital control system on an ordinary milling machine and can perform milling more accurately under the control of the program code. When the milling machine is working, it needs to be improved: [0003] 1. When the milling cutter is processing, the workpiece is directly placed on the milling machine...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a gantry CNC milling machine to solve the problem that when the milling cutter is processing the workpiece, the workpiece is directly placed on the milling machine without fixing the workpiece, causing the milling cutter to , the workpiece will be displaced, so that the milling cutter cannot process the workpiece uniformly, resulting in a low processing effect of the workpiece. It is necessary for the staff to adjust the position of the workpiece in real time to reduce the processing efficiency of the milling machine; after the milling machine finishes processing the workpiece, it cannot Adjusting the milling cutter to a certain height will cause the milling cutter to easily collide with the processed parts, causing damage to the position where the milling cutter collides with the milling cutter, resulting in defective products, and may damage the milling cutter, especially the milling cutter with poor toughness Knives, its scrapping will increase the production cost and reduce the production efficiency
