Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, and discloses a numerical control cutting tool convenient for chip removal. Background Art

[0002] A milling cutter is a common numerical control cutting tool on a numerical control machine tool. Usually, a plurality of helically distributed cutting teeth are arranged on the milling cutter. The milling cutter is usually installed on the mounting seat of the numerical control machine tool. The mounting seat is driven by a motor on the numerical control machine tool to rotate. When the milling cutter works, it rotates. Each cutting tooth on the milling cutter intermittently cuts off the surplus of the workpiece in turn. Knife grooves are formed between the cutting teeth of the milling cutter. Part of the debris can be discharged along the knife grooves when the milling cutter rotates for milling. The milling cutter is mainly used for processing planes, steps, grooves, etc.

[0003] When the existing numerical control cutting tool works, when the numerical control cutting tool processes metal materials, a large amount of debris is easily adhered to the milling cutter, which affects the processing. And when the milling cutter usually processes groove structures such as grooves, the debris is easily left at the bottom of the groove. When the milling cutter is processing, it is easy to drive the debris to rotate together. The debris is easy to rub against the bottom and wall of the groove, which affects the processing effect, and is easy to cause the milling cutter and the debris to be extruded and damaged. Content of the Utility Model

[0004] The purpose of the utility model is to provide a numerical control cutting tool convenient for chip removal aiming at the above existing problems and deficiencies. The spray pipe and the discharge holes can better clean and remove chips from the milling cutter, and can better adjust the amount of cutting fluid sprayed, effectively avoiding the influence of debris on processing.

[0006] An installation frame is arranged outside the upper end of the milling cutter. An installation groove is opened below the installation frame. A discharge groove is opened on the upper surface of the milling cutter. A plurality of discharge holes are opened on the left and right surfaces and the lower end of the inner wall of the discharge groove. A connecting ring is connected to the outside of the milling cutter. A ring pipe is embedded and fixed at the inner edge of the connecting ring. The left and right ends of the discharge groove are both communicated with a discharge pipe. The discharge pipe is communicated with the ring pipe. The lower end of the ring pipe is communicated with spray pipes distributed at equal intervals in a ring shape. The lower end of the spray pipe penetrates through the connecting ring;

[0007] A connecting pipe penetrates and is fixed at the right end of the installation plate. An electromagnetic valve is installed outside the connecting pipe. A camera is installed below the installation plate. The connecting pipe is used for introducing cutting fluid.

[0008] Further, the lower end of the spray pipe faces the milling cutter. The discharge holes are all arranged upward. The installation frame is connected to the milling cutter by bolts.

[0009] Further, a ring groove is opened on the upper surface of the installation frame. A connecting head is installed on the top surface inside the installation groove. A through hole is opened on the lower surface of the inner wall of the ring groove.

[0010] Further, the through hole communicates with the connecting head, and the outer wall of the connecting head fits against the upper end of the inner wall of the discharge groove.

[0011] Further, the left end of the connecting pipe is inserted into the annular groove, and rubber gaskets are fitted against the upper edge of the inner wall of the annular groove and the upper end of the inner wall of the installation groove.

[0012] Advantages of the utility model:

[0013] After the user installs the milling cutter, cutting fluid is introduced into the annular groove through the connecting pipe. At this time, the cutting fluid can enter the through hole and then into the discharge groove, and the cutting fluid sprayed by the spray pipe flushes the debris on the outer wall of the milling cutter, achieving a better chip removal effect.

[0014] The cutting fluid that enters the discharge groove can also be sprayed out through the discharge groove and a number of discharge holes. The cutting fluid sprayed out from the discharge holes located below the milling cutter can clean the debris at the bottom of the milling cutter when the milling cutter is performing cutting operations on groove-like positions such as grooves. The spray pipe and the discharge holes can cooperate well to clean the milling cutter and prevent debris from affecting the processing.

[0015] The solenoid valve and the camera are both communicatively connected to the central control module of the numerical control machine tool. The camera can monitor the condition of the debris on the surface of the milling cutter, and adjusting the opening degree of the solenoid valve can adjust the amount of cutting fluid sprayed. The user can adjust the opening degree of the solenoid valve according to the amount of cutting fluid required for cleaning and chip removal of the milling cutter, thereby achieving a better chip removal effect.
