Numerical control milling machine tool looseness protection device

Abstract

A numerical control milling machine tool looseness protection device comprises a movable rod. A rack is arranged on the right side of the movable rod. A sliding body is arranged on the right side of the movable rod. A locking mechanism is arranged between the sliding body and the movable rod. A friction block is fixedly arranged on the lower side of the movable rod. The friction block is fixedly arranged on the lower side of the sliding body. An arc-shaped body is fixedly arranged on the right side of the movable rod. The device is installed at the assigned position of a machine tool, the non-acting part of a tool is covered by the device, beating of the tool can be detected by the device, and when accidents happen, the protection device is rapidly started, the tool which is out of controlis prevented from flying out, and life safety of operators is protected; the device is high in adaptability and can be installed on most of numerical control milling machines; and the device is compact in tail end structure, is not likely to generate interference and does not occupy much machining space.

Description

technical field [0001] The invention relates to the field of numerical control milling machines, in particular to a tool release protection device for numerical control milling machines. Background technique [0002] CNC milling machine can process parts that cannot be processed by ordinary machine tools or are difficult to process. It has a high degree of automation and can reduce the labor intensity of the operator. Therefore, it is widely used in modern enterprises. Compared with traditional machine tools, CNC machine tools use a lot of electrical, Hydraulic and electromechanical devices lead to an increased probability of failure. The loose tool of the machine tool may fly out, especially when cutting metal. Therefore, it is very necessary to prevent the tool from flying out and hurting people. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tool release protection device for a CNC milling machine, which ov...
