A CNC machine tool for a revolver ejection tool changer for machining

Abstract

The invention discloses a numerically controlled machine tool with a left-wheel ejection type tool magazine for mechanical processing. Seat, barometer, the present invention realizes the use of the roulette tool magazine frame to cooperate with the processing warehouse, and the six-hole roulette rotation operation of the tool magazine frame for tool change through the use of the revolver gun to change the bullet effect, combined with the linear speed tool magazine groove barrel one by one The protective tool is telescopically advanced, combined with the angular speed rotation of the roller shaft to form a small gap output effect for angle adjustment, which narrows the blade groove and seals it, and prevents the reaction force of cutting powder from bouncing into the tool magazine. It has strong anti-interference and optimizes the level. The distance from the circular surface of the rotating knife forms the linear step feed control effect of the axial flow air pump valve of the pointed blade cylinder, which is electronically controlled and pneumatically controlled. The line replaces the surface to reduce the power of the knife movement, and then provides the mechanical transmission of other internal parts. The gap improves the coordination of equipment work and maintains the tool to work efficiently.

Description

Technical field[0001]The present invention is a CNC machine tool for machining a revolving tool for machining, which belongs to the field of CNC machine tools.Background technique[0002]CNC machine tools are the preferred precision instruments for plastic workpieces and iron workpieces cutting parts, and the three-axis stereo coordinate system constitutes the effect of fixed-point feed displacement, so that the original operation of artificial drama has achieved great progress, driving the machining industry The chain is carried out and manufactured, and the knife library in the CNC machine tool is an indispensable core component. The shortcomings of the current technical public to be optimized are:[0003]In the CNC lathe, the linear speed takes time to take the knife time than the time delay of the angular velocity displacement of the rotary tool holder, so in order to enter the knife, most of the swivel tool holder is selected. The rotation of the knife will form a cutting operation...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a numerically controlled machine tool with a left-wheel ejection type tool changer for mechanical processing, so as to solve the problem of linear velocity cost during the horizontal and vertical displacement of the row tool holder in the numerically controlled lathe. The time delay is longer than the time consumed by the angular velocity displacement of the rotary tool post. Therefore, for the short-term efficiency of the tool feeding effect, most of the rotary tool post is used, and the rotation of the tool change will form a cutting operation in the internal environment, which will affect the overhead of the internal environment of the tool magazine. It is necessary, this will result in a large space and low utilization rate, a large area of ​​the rotating circle, resulting in a relatively compact mechanical transmission structure of other chucks on the lathe, resulting in a high proportion of space occupied by the tool holder, which will cause joint damage when the tool is pulled out. The expansion of the side frame opening reserves a large space to store cutting powder impurities, which interferes with the cleaning of equipment in the later stage, and causes the tool to be contaminated with oil, water, powder and chips, resulting in hidden dangers of passivation.
