[0041] In this embodiment, when installing the tool, the cover 403 is screwed onto the cover plate 402 to form a closed space inside the cover plate 402, thereby achieving the purpose of guiding, collecting and processing the debris during the processing, and preventing the debris from splashing around and causing damage to other surrounding equipment. After completing the processing of the workpiece, the tool is removed, and then the cover 403 is twisted to separate it from the cover plate 402. At this time, the top of the cover plate 402 is in an open state, which is convenient for cleaning the collected debris.
[0042] The use method and working principle of the device: When the drilling tool is used, the drilling cutting edge 11 is set at the bottom of the tool handle 1. After the fixed head 306 is fixed to the chuck of the tool holder, the tool holder is used to drive the tool to rotate. The high-speed rotation of the drilling cutting edge 11 can complete the cross hole processing of the workpiece. After completing the drilling of the cross hole, the tool handle 1 is controlled to adjust its position through the matching setting of the inner chamfer 12, the transition surface 13, the outer chamfer 14 and the edge 15 above the drilling cutting edge 11. The outer chamfer 14 is used to form a chamfer at the junction of the cross hole and the outer diameter to achieve the effect of deburring. Then, the tool is lifted upward, and the 3D chamfering function is used at a suitable position. The inner chamfer 12 is used to form a chamfer at the junction of the cross hole and the inner hole to achieve the effect of deburring. The tool returns to the center of the cross hole, lifts up the tool, and removes the burrs turned inward in the cross hole. At this time, the drilling, chamfering and deburring of the workpiece are completed, and the purpose of completing multiple processing processes with a single tool can be achieved, which simplifies the processing technology, improves the processing efficiency, and reduces the production cost. When the workpiece is drilled, chamfered and deburred by the operation of the tool handle 1, metal debris will be generated when the workpiece is cut. Through the coordinated setting of the first chip groove 9 and the second chip groove 10 on the surface of the tool handle 1, the first chip groove 9 and the second chip groove 10 can guide and control the direction of the debris, ensure the orderly discharge of the debris generated during processing, keep the processing position clean, and avoid the debris adhering to the surface of the workpiece to affect Machining accuracy, through the arrangement of the chip removal holes 16 on the inner surfaces of the first chip removal groove 9 and the second chip removal groove 10, when the chips are generated and pass through the grooves, the chips will slide close to the inner walls of the first chip removal groove 9 and the second chip removal groove 10 under the action of centrifugal force, and at this time, the chips will pass through the chip removal hole 16 position with a drop, and the chips will enter the circular hole 8 through the chip removal hole 16 position. When the tool is driven to run at high speed, through the arrangement of the driving blade 210 above the tool handle 1, the airflow generated when the tool handle 1 rotates at high speed will act on the surface of the driving blade 210, and at this time, the driving blade 210 can drive the driving shaft 208 to follow the rotation, and the driving shaft 208 can drive the first support shaft 201 to follow the rotation through the connection with the first bevel gear 204. The rotation of the shaft 201 can drive the first spiral blade 202 to rotate accordingly. At this time, since the debris is discharged into the circular hole 8 through the chip discharge hole 16, the rotation of the first spiral blade 202 can transport the incoming debris. At this time, the debris will move upward through the rotation of the first spiral blade 202. While the first spiral blade 202 is running, the first bevel gear 204 can drive the second support shaft 206 to rotate accordingly through the engagement with the second bevel gear 205. The second support shaft 206 can drive the second spiral blade 207 to rotate accordingly. At this time, the debris is driven to move to the uppermost position through the rotation of the first spiral blade 202. The setting of the baffle plate 203 above the first spiral blade 202 can play a role in limiting protection.To prevent the debris from affecting the operation of the first bevel gear 204 and the second bevel gear 205, the debris moves to the side tube 6 position, and the debris can be transferred through the rotation of the second spiral blade 207 so that the debris is discharged through the side tube 6 position. At this time, the sleeve plate 401 and the cover plate 402 are used in conjunction with each other. The cover plate 402 is supported by the sleeve plate 401 and is sleeved on the outer position of the side tube 6, so that the discharged debris can be supported, that is, the debris discharged from the side tube 6 position will enter the cover plate 402 for storage. When installing the tool, the cover 403 is covered on the cover plate 402 through a threaded cover, so that a closed space is formed inside the cover plate 402, thereby realizing the control of the debris during the processing. The purpose of guiding the collection and processing is to prevent the debris from splashing around and causing damage to other surrounding equipment. After completing the processing of the workpiece, the tool is removed, and then the cover 403 is twisted to separate it from the cover plate 402. At this time, the top of the cover plate 402 is in an open state, which is convenient for cleaning the collected debris. When installing and using the tool, the third fixing plate 304 can be separated from the second fixing plate 303 after the loose nut 308 is removed. At this time, the third fixing plate 304 can drive the fixing head 306 to be separated and removed. Then, the fixing head 306 and the tool handle 1 can be detached and installed. Different fixing heads 306 can be replaced according to the size of the matching tool holder for use, which improves the convenience of using the tool.
