A machine tool protective cover capable of realizing secondary door opening

Abstract

The invention discloses a machine tool protective hood capable of secondary opening of doors. The machine tool protective hood comprises a machine tool, rotary limiting plates are movably arranged onthe two sides of a working area in the machine tool through hinges, the rotating protective doors are movably arranged on the outer side end faces of the two rotary limiting plates, balls are movablyembedded in the bottom ends of the rotary protective doors and clamped in sliding rails in a rolling mode, and the sliding rails are fixedly installed at the part, on the outer side of the working area, of the machine tool. In the machine tool protective hood, the protective doors include the rotary protective doors and mobile protective doors, generally, the working area can be closed and openedonly by pulling the mobile protective doors instead of opening the rotary protective doors, and the protective doors can be opened for the first time by moving the mobile protective doors on the two sides leftwards and rightwards; and when the machine tool needs to be overhauled, a fixing bolt block can be pulled, the rotary protective doors are pulled out, the balls at the bottoms of the rotary protective doors are located at the inner ends of the straight sliding rails accordingly, the rotary protective doors can be opened along the track of the arc sliding rails, and secondary opening of the protective doors is achieved.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to a machine tool protective cover capable of realizing secondary door opening. Background technique [0002] Machine tools are generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. The final machining is done by cutting on the machine tool. [0003] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can also be used for corresponding processing on the lathe. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces, and are the most widely used machine tools in machinery manufacturing and repair factories. I...

Problems solved by technology

In the process of machine tool processing, due to the high-speed operation of machine tools such as drills, a large amount of metal debris will be splashed out, and the speed and direction of the debris splashing can not be determined. There is a sliding protective door, and then in the process of machine tool debugging or maintenance, it is necessary to ensure that there is a certain operating space in the working area. Due to the structural limitations of the machine tool in the prior art, the opening area of ​​​​the protective cover is limited. During the later maintenance process Inconvenient, for this reason we propose a machine tool protective cover that can realize secondary door opening to solve the above problems
