Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and more particularly to a telescopic protective cover for CNC machine tools. Background Technology

[0002] CNC machine tools are automated machine tools equipped with a program control system, mainly used for milling, boring, drilling, and tapping of metal products such as iron, steel, copper, and aluminum. The workpiece needs to be mounted on the machine tool's slide, and the spindle drives the cutting tool to rotate, thus machining the workpiece. To prevent chips from falling onto the moving mechanism of the slide, protective covers need to be installed on both sides of the slide. Currently, the protective covers used for machine tool slides are generally accordion-style covers. This type of cover is usually made of relatively soft materials, which are easily punctured by metal chips, have a short service life, and also easily accumulate chips, making them difficult to clean. Summary of the Invention

[0003] The problem to be solved by this utility model is to provide a telescopic protective cover for CNC machine tools, which improves the protection strength and facilitates cleaning.

[0004] To solve the above technical problems, a telescopic protective cover for CNC machine tools provided by this utility model is provided, comprising a head end cover assembly, several intermediate section cover assemblies, and a tail end cover assembly. Each of the head end cover assembly, intermediate section cover assembly, and tail end cover assembly includes a C-shaped cover plate and an end panel. The end panel is detachably connected to one end face of the C-shaped cover plate. Several buffer members are detachably connected to the outer edge of the end panel of the tail end cover assembly and intermediate section cover assembly. One end of the buffer member extends beyond the outer side of the end panel. The C-shaped cover plates of the head end cover assembly, each intermediate section cover assembly, and the tail end cover assembly are stacked sequentially from the inside to the outside and can move along the length direction of the C-shaped cover plate. A clearance notch is provided at the bottom of the end panel, and sliders can be detachably connected to both sides of the clearance notch.

[0005] Preferably, the top of the C-shaped cover plate of the head end cover assembly is fixedly connected with a connecting angle bracket, and the connecting angle bracket is provided with connecting holes. Two connecting plates are arranged side by side on the inner side of the C-shaped cover plate of the tail end cover assembly.

[0006] Preferably, one end face of the C-shaped cover plate has a plug-in portion distributed thereon, and the end face plate has a plug-in hole corresponding to the plug-in portion through it, and the plug-in portion is inserted into the plug-in hole.

[0007] Preferably, the buffer includes a first annular portion, a second annular portion, and a connecting portion connecting the first annular portion and the second annular portion. The edge of the end panel is provided with a groove that matches the connecting portion, and the longitudinal section of the connecting portion is an isosceles trapezoidal shape.

[0008] Preferably, the outer end faces of the first and second annular portions on the C-shaped cover plate are adjacent to the inner wall of the adjacent C-shaped cover plate.

[0009] The beneficial effects of this utility model are as follows: This utility model provides a telescopic protective cover for CNC machine tools. The C-shaped cover plate of the head end protective cover assembly is fixed to one end of the machine tool slide, and the C-shaped cover plate of the tail end protective cover assembly is fixed to the machine tool bed. The machine tool slide is slidably connected to two slide rails of the machine tool. The two slide rails of the machine tool respectively support the two side sliders, so the C-shaped cover plate of the tail end protective cover assembly cannot move. When the machine tool slide moves towards the tail end protective cover assembly side, the machine tool slide will drive the C-shaped cover plate of the head end protective cover assembly to move towards the C-shaped cover plate side of the tail end protective cover assembly. The slider can move along the slide rails of the machine tool. When the end panel of the end guard assembly contacts the buffer of the adjacent intermediate section guard assembly, the end panel of the head end guard assembly will push the C-shaped cover plate of the adjacent intermediate section guard assembly towards the C-shaped cover plate side of the tail end guard assembly. This process continues, allowing the C-shaped cover plates of the tail end guard assembly and intermediate section guard assemblies to retract into the C-shaped cover plate of the head end guard assembly. When the machine tool slide moves away from the tail end guard assembly, the machine tool slide will drive the C-shaped cover plate of the head end guard assembly to move away from the tail end guard assembly. This allows the C-shaped cover plates of each intermediate section guard assembly to extend and reset sequentially. Its structure is simple, provides good protection, has good structural stability, and is easy to clean. Attached Figure Description
