The utility model belongs to the technical field of the cutter of cutting metal material, especially, relate to a lathe tool to deep hole cutting that uses on lathe.
[ background of the invention ]
Currently, lathe equipment used in machining and manufacturing industries is diverse. The turning tool for cutting the workpiece arranged on the lathe is selected according to the shape, material, technical requirements and the like of the workpiece. The turning tools are classified according to structures: the turning tool can be an integral turning tool or a welding turning tool. Classified by functional role: can be an internal lathe tool, an external lathe tool, a 90-degree end surface deflection tool, a cutting tool, a thread tool, a forming tool and the like. The excircle, the inner hole and the end surface of a workpiece to be processed are cut to form a smooth surface, a thread, a turning groove and the like. The most common lathe tool is a welded lathe tool, namely, a tool groove is formed on a carbon steel cutter bar according to the requirement of the geometric angle of the tool, a hard alloy blade is welded in the tool groove by using a welding material, and the lathe tool is used after being sharpened according to the selected geometric parameters. Although the welding type turning tool is widely used for cutting a workpiece on a lathe, when a deep hole or a blind hole with the size larger than 200 mm of a high-diameter flange is machined, the welding type turning tool also has the following defects: the cutter bar is easy to generate high-frequency vibration, and the cutter point and the cutting edge are quickly worn and easily generate the phenomenon of cutter jumping; the service life of the turning tool is short; when the hard alloy blade is damaged, the cutter bar is detached along with the hard alloy blade, and the utilization rate of the cutter bar is low; the cutter body is heavy, the cutter grinding is very inconvenient, the working hours are taken, and the production efficiency is lower.
[ summary of the invention ]
The utility model aims to provide a lathe tool that cutting major diameter flange hole used. When the turning tool is used for cutting, the cutter bar is not easy to generate high-frequency vibration, and the service life of the cutter point and the cutting edge is prolonged; when the cutting edge of the lathe tool is ground, the grinding machine is convenient and time-saving; and simultaneously, the use efficiency of the cutter bar is improved.
The technical scheme of the utility model as follows:
the utility model provides a lathe tool that cutting major diameter flange hole was used, is including the cutter arbor 101 of the horizontal cylinder shape of axis, and its cutter arbor 101's right-hand member is provided with the handle of a knife 102 of the horizontal cuboid shape of cross-section for the rectangle, its characterized in that: a rectangular hole 104 with the axis vertical to the axis of the cutter rod 101 and horizontally arranged back and forth is arranged at the position of the left end cutter head 103 of the cutter rod 101,
a small knife handle c202 of a small turning tool a2 is arranged in the rectangular hole 104,
a screw 3 with an axis perpendicular to the axis of the cutter rod 101 is arranged above the rectangular hole 104.
The small turning tool a2 is an inner bore turning tool.
The small turning tool a2 is an inner hole threading tool.
The small turning tool a2 is an inner hole annular groove cutter.
The small turning tool a2 is an inner hole forming tool.
The utility model discloses the cutter arbor 101 that sets up is the cylinder shape, and its cross section is great, and mechanical properties obtains improving, especially prevents quivering the performance and obviously improves, is difficult for producing the sword phenomenon of jumping, has reduced the wearing and tearing of knife tip and blade, has prolonged the life of lathe tool.
The position of the small turning tool a2 is set at the position of the cemented carbide insert at the position of the tool bit 103 at the left end of the tool holder 101. The small turning tool a2 is used to replace carbide blade. When the trolley cutter a2 is used for polishing the cutting edge or is replaced, the screw 3 is loosened, the small turning tool a2 can be dismounted, the heavy cutter bar 101 does not need to be dismounted together, the labor intensity is reduced, and the production efficiency is improved. The use efficiency of the tool bar 101 is also improved. According to the requirement, the small turning tool a2 can be made into an inner bore turning tool, an inner bore threading tool, an inner bore annular groove cutting tool and an inner bore forming tool. The ranges of the front clearance angle, the side clearance angle, the rear bevel angle and the side bevel angle of various cutting edge angles required for cutting on the trolley cutter a2 do not need to be changed.
The utility model discloses beneficial effect as follows: by using the technology, the cutter bar is not easy to generate high-frequency vibration when the turning tool is used for cutting, and the service life of the cutter point and the cutting edge is prolonged; moreover, when the cutting edge of the lathe tool is ground, the grinding machine is convenient and time-saving; meanwhile, the technical effect of the cutter bar using efficiency is also improved. The utility model has simple structure
