Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining, and more specifically to a chip removal mechanism for a numerical control machine tool. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] The current CNC machine tools mainly clamp the workpiece by means of a fixture on the workbench. During processing, the chips and cutting fluid generated during processing tend to remain on the surface of the workbench. In order to avoid the accumulation of chips, it is necessary to continuously clean and remove the chips.

[0004] Chip removal, which can be done manually by hand-held air blowing, requires shutting down the CNC machine tool, which can easily affect the processing efficiency. It is impossible to continuously collect and centrally discharge chips and cutting fluid during the processing. Manual cleaning is time-consuming and labor-intensive, and there are residues, which cannot guarantee the processing environment of the workpiece. In view of this, we propose a chip removal mechanism for CNC machine tools. Utility Model Content

[0009] The utility model realizes the collection of cutting fluid and debris during the workpiece processing by means of a blocking groove with an extended blocking in cooperation with a trapezoidal bottom plate; after the cutting fluid and debris flow into the two confluence grooves through the trapezoidal bottom plate, the cutting fluid and debris in the confluence groove are continuously moved to the discharge structure by means of two belt conveyors, and the cutting fluid and debris are discharged through the discharge structure; during the processing, the extended blocking arranged on the blocking groove plays a blocking effect, preventing the cutting fluid and debris from flying out; during the processing, the two belt conveyors can continuously collect and centrally discharge the debris and cutting fluid, thereby improving the processing efficiency of the workpiece, saving time and labor, and not easily leaving residues, thereby ensuring the processing environment of the workpiece.

[0010] Preferably, the discharge structure includes two guide flow channels, the guide flow channels are fixedly arranged at the bottom of one side of the enclosure groove, and the guide flow channels are connected to the corresponding guide flow channels.

[0011] Preferably, the two guide flow channels are connected to a discharge bucket at one end away from the enclosure groove, and the discharge bucket is tilted downward at one end away from the guide flow channel.

[0012] Preferably, the trapezoidal bottom plate is formed with a layout plane and diversion slopes located on both sides of the layout plane in the enclosure groove, and the ends of the diversion slopes are combined with the confluence groove.

[0014] Preferably, one end of the guide flow channel toward the enclosure groove is provided with a scraping slope for scraping cutting fluid on the conveyor belt of the belt conveyor, and the scraping slope is attached to the low position of one end of the conveyor belt on the belt conveyor.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model realizes the collection of cutting fluid and debris during the workpiece processing by means of a retaining groove with an extended retaining member in cooperation with a trapezoidal bottom plate. When the cutting fluid and debris flow into two confluence grooves through the trapezoidal bottom plate, the cutting fluid and debris in the confluence groove are continuously moved to a discharge structure by two belt conveyors, and the cutting fluid and debris are discharged through the discharge structure. During the processing, the extended retaining member provided on the retaining groove plays a retaining role to prevent the cutting fluid and debris from flying out.
