Water spraying device for milling based on precision numerical control machine tool

Abstract

The invention discloses a water spraying device for milling based on a precision numerical control machine tool. The water spraying device comprises a machine tool spindle. The bottom end of the machine tool spindle is fixedly connected with a tool rest; a damping mechanism is fixedly connected to the bottom end of the outer side of the machine tool spindle; and the damping mechanism comprises a fixing ring, a mounting groove, a limiting groove, a fixing groove, an offset block, a connecting block, a limiting block, a buffer spring, a connecting round block, a buffer rubber pad and a mountingbox. Through cooperation of a special-shaped ring, a sealing pipe, a sealing spring, a sliding rod and a special-shaped block, the size of an opening between the special-shaped ring and the special-shaped block is adjusted, so that flow velocity of cooling liquid in a spray housing keeps dynamic balance, the cooling liquid can be sprayed to a cooling position all the time, and the cooling effect is improved; and through cooperation of the annular groove, the control pipe, the spiral driving groove, the driving connecting rod and the connecting disc, the spraying flow speed of the cooling liquid is changed, and the using process of the water spraying mechanism is optimized.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a water spray device for milling based on precision numerical control machine tools. Background technique [0002] Numerical control machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system, which can logically process programs with control codes or other symbolic instructions, and decode them, using coded numbers It means that the numerical control device is input through the information carrier, and various control signals are sent by the numerical control device after calculation processing to control the movement of the machine tool, and automatically process the parts according to the shape and size required by the drawing. The cutting position is cooled by water spraying device; [0003] However, due to the change of the pressure in the coolant pipeline during the spr...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a water spray device based on precision numerical control machine tool milling, which can effectively solve the problem that the water spray device proposed in the background art is sprayed from the nozzle due to pressure changes in the coolant pipeline during the water spray process. After leaving, the movement distance fluctuates, and the expected position cannot be continuously cooled, which reduces the cooling effect.
