AI Technical Summary
The existing CNC grinder protective doors are prone to jamming due to the accumulation of grinding chips and dust on the slide rails during grinding, resulting in unsmooth push and pulling and abnormal noise problems.
A new type of protective door is designed, and a driving mechanism is used to drive the reciprocating screw through the first motor, so that the protective plate can be lifted and moved, avoiding the use of transverse slide rails. At the same time, a rotating shaft and a second motor are provided to allow the guard plate to flip quickly and rotate automatically.
By eliminating the problem of debris accumulation on the slide rails, the opening and closing of the protective doors become smoother, avoiding abnormal noises, and improving the practicality and automation of the protective doors.

[0002] A CNC grinding machine is a machine tool that uses grinding tools to grind the surface of workpieces. During the grinding process of a CNC grinding machine, the workpiece to be ground needs to be placed inside the grinding chamber for grinding. The protective door of the CNC grinding machine is a device that separates the grinding area from the external area of the equipment during grinding.
[0003] Most of the existing protective doors of CNC grinding machines are arranged on both sides of the operation port of the CNC grinding machine and move in a translation manner. Some are electrically driven, and some are manually opened. These protective doors are all provided with slide rails to support the protective doors. During the operation of some grinding machines, grinding chips and dust are likely to fall on the slide rails and jam the protective doors, resulting in problems such as unsmooth pushing and pulling of the protective doors and abnormal noises. Therefore, it is necessary to design a new protective door for a CNC grinding machine to solve the above problems. Content of the Utility Model
