Description

Vertical lathe chip discharge device

The invention relates to a vertical lathe chip discharge device, in particular to a worktable not only in the overall structural design, but also can be applied to various worktables of different sizes and sizes, and there is no low rotation speed of the worktable. The chip stacking device is incapable of being discharged, and can independently control the chip removing speed and the direction of rotation, increasing the convenience and safety of use, and innovating the vertical lathe chip discharge device with more practical functions in its overall implementation. Designer.

Press, generally common vertical lathe, which will produce chips during the processing with the rotary table, and the generated chips will pass through the inclined bed set on the outer circumference of the workbench, and rinse with the chip water. It is discharged from the outside of the workbench to achieve the effect of chip removal. However, since the above-mentioned chip removal method requires manual work, it will affect the overall processing efficiency of the vertical lathe.

Therefore, some companies have developed such as Japanese Patent Special Open 9-11780 No. 5, the structure is fixed on the outer circumference of the table with a large-diameter chip-bearing sheet metal, and then the centrifugal force generated during the rotation of the table is used to pry the chips falling on the sheet metal of the chip-receiving plate, and the chip-bearing The outer periphery of the plated gold is provided with a protective sheet metal, so that when the chips are blown to the chip discharge port of the protective sheet metal, the chips will fall to the chip recovery device and achieve the function of chip discharge; however, the above structure is used in execution due to The chip-receiving sheet metal is rotated synchronously by the table, so that when the low-speed rotation is performed, due to insufficient centrifugal force generated, the chips are easily accumulated on the chip-receiving sheet metal and the protective sheet metal is combined with the chip-receiving sheet metal base plate. On the groove, the cleaning is greatly inconvenient, and when it is stopped at the workbench, the chip-bearing sheet metal is not uniquely controlled, and the trouble of in-dust cleaning is inconvenient, resulting in the overall structural design. There is still room for improvement.

In addition, please refer to Japanese Patent Laid-Open No. 2007-203384, which is also fixed to the outer circumference of the table by a large-diameter retainer, so that the retainer and the table rotate synchronously to smash the chips by centrifugal force. And the scraper plate is arranged on the retainer plate, so that the scraping plate can be used to take the chip to the chip discharge port to collect and collect while the table is rotated, and the upper edge of the outer peripheral edge of the retainer plate is provided with the upper edge. The retaining member of the protrusion prevents the chip from entering; however, since the upper edge of the block and the lower edge of the retainer need to be adjusted in clearance, the gap is not easy to adjust, and the same is to make the retainer and the table synchronously When rotating at low speed, the centrifugal force is insufficient, and the chips are easy to accumulate on the retainer. When the motor rotates at high speed, the retainer and the table rotate at a high speed, which is dangerous. When the table is stopped, the retainer cannot be unique. Control operations have resulted in room for improvement in overall structural design.

The reason is that the inventor has been rich in design and development and practical production experience of the relevant industry for many years, and has researched and improved the existing structure to provide a vertical lathe chip discharge device, in order to achieve better practical value.

The main object of the present invention is to provide a vertical lathe chip discharge device, which mainly uses a power device to drive a transmission chain with a sprocket, so that the scraper ring does not rotate synchronously with the table, so that it is not only in overall structural design. Simplified, it can be applied to various worktables of different sizes and sizes, and since it is not subjected to chip removal by centrifugal force in operation, it is not caused by the low speed of the table, and the chip accumulation card cannot be discharged. The utility model can independently control the chip removal speed and the rotation direction, and increases the convenience and safety of use, and the utility model has more practical utility characteristics in its overall implementation.

The utility model is provided with a fixed retaining sheet metal, a chip flute is formed on the retaining sheet metal, and a chip discharging port is arranged on the flute side of the retaining plate on the machine side; wherein: the inner edge of the retaining plate is provided with gold a scraping ring, the scraping ring is fixed on the inner edge of the fixing chain and the upper chain of the transmission chain, a scraper is fixed on the outer edge of the scraping ring, and a power device is arranged on the machine. The output end of the device is connected and driven by a chain wheel and a chain portion under the transmission chain.

In a preferred embodiment of the vertical lathe chip discharge device of the present invention, the machine table is provided with a guide ring corresponding to the inner edge of the upper chain portion of the transmission chain, so that the transmission chain can rotate outside the guide ring.

In a preferred embodiment of the vertical lathe chip discharge device of the present invention, the machine table is provided with a cover corresponding to the scraper ring, the drive chain and the guide ring.

In a preferred embodiment of the vertical lathe chip discharge device of the present invention, a dustproof ring fixed to the work table is disposed above the cover.
