A NC Milling Tooling That Can Reduce Workpiece Deformation

Abstract

The invention relates to a numerical control milling tool capable of reducing deformation of a workpiece. The tool comprises a platen, a moving rack, an electric slide block and a milling mechanism. The moving rack is mounted at the upper end of the platen, the electric slide block is mounted at the lower end of the moving rack, the milling mechanism is mounted at the lower end of the electric slide block and comprises a driving moor, a driving connecting part, a knife handle, a milling cutter and a cooling branch chain, the driving connecting part comprises a connecting cap, a compacting rack, an auxiliary motor and an auxiliary rod, the cooling branch chain comprises a rotating block, a liquid spraying barrel, a liquid outlet and a liquid storage device, the liquid storage barrel comprises a barrel body, a piston rod, a reset spring and a shielding sheet. Most parts of the milling mechanism are connected detachably, so that the parts are detached and maintained conveniently. In the milling process, the cooling branch chain can reduce the temperature of the milling cutter, can reduce the thermal deformation degree of the workpiece as a result of too high temperature, and improvesthe processing quality.

Description

technical field [0001] The invention relates to the field of milling processing equipment, in particular to a numerically controlled milling processing tool capable of reducing workpiece deformation. Background technique [0002] Milling is to fix the blank, and use a high-speed rotating milling cutter to move on the blank to cut out the required shape and features. Traditional milling is mostly used for simple shape features such as milling contours and grooves. CNC milling machines can process complex shapes and features, so they are more and more widely used. [0003] When processing thin-walled workpieces, due to the complex structure and relatively low rigidity of thin-walled workpieces, there are the following problems in the processing process: [0004] (1) Under the action of cutting force, cutting heat, clamping force and stress, thin plate parts are prone to distortion and deformation. Once the deformation exceeds the allowable range, the product quality cannot be...

AI Technical Summary

Problems solved by technology

[0004] (1) Under the action of cutting force, cutting heat, clamping force and stress, thin plate parts are prone to distortion and deformation. Once the deformation exceeds the allowable range, the product quality cannot be guaranteed. In order to reduce the degree of deformation of the workpiece, it is necessary to Use coolant to cool the workpiece and milling cutter during milling

[0005] (2) During the use of the existing coolant, the injection range of the coolant is not accurate enough, which not only increases the amount of coolant used, but also often adheres to the surface of the workpiece, and the worker needs to clean the workpiece afterwards. Added unnecessary trouble
