Abstract
The utility model relates to a turning tool, comprising a tool bit, a tool bar and a fastener. When using, the tool bit and the tool bar are tightly fastened together via the fastener. When a cutting edge is worn or broken, the tool bit can be replaced via loosening the fastener. Therefore, the utility model has the advantages of easy use high production efficiency and material saving.
Description
The utility model relates to a kind of lathe tool.
At present, lathe tool is the overall structure of being made up of cutter head and knife bar mostly.Cutter head is used for cutting, and knife bar is used for gripping.Because cutting force is bigger, the knife bar stock size is bigger.Broken or during can not having used again of tool bit abrasion, knife bar will be scrapped with cutter head, throw away when cutter head, this is a kind of no small waste.
The purpose of this utility model be to improve the shortcoming of prior art and provide a kind of lathe tool be divided into cutter head, knife bar, with the combination lathe tool of three unitary part of securing member, fit together during use, interchangeable cutter head behind the tool bit abrasion, gone bad and to have thrown away, scrap, knife bar and securing member keep use all the time, can enhance productivity like this, save steel.
The utility model purpose be achieved in that lathe tool by three of cutter head, knife bar and securing members in addition parts form.The front portion of cutter head is a blade, and the rear portion is a cone, and along the circular cone center line one blind screwed hole is arranged.There is a conical bore that is complementary with cutter head rear portion cone the knife bar front portion, and along the bar center line central through hole that is less than or equal to the conical bore base diameter is arranged, and there is the circular groove section of a diameter greater than central through hole at the knife bar rear portion.Securing member is a steel pole that can pass the knife bar central through hole, its head has the screw thread that is complementary with the blind screwed hole of cutter head, there is one section cylindrical section that is complementary with knife bar circular groove section diameter at its rear portion, and regular hexagon or the foursquare groove that can screw are arranged in the cylindrical section tail end.The length of steel pole should be able to tighten up cutter head and knife bar, behind knife bar that cutter head is packed into, insert steel pole from the other end of knife bar, screw steel pole, the thread segment of steel pole head screws in the screwed hole of cutter head, the conical bore of the cone at cutter head rear portion and knife bar front portion fits tightly, and steel pole rear end cylindrical section is tightly conflicted at the bottom of the circular groove at knife bar rear portion.Cutter head and knife bar constitute an integral body by securing member, can be used to cut other part.Cutter head has been broken, but loosening fasteners takes off cutter head, and other changes a new cutter head, works on.
The utility model is simple in structure, easy to use, the same knife bar different cutter heads that can change the outfit, so economical with materials, production efficiency height.
