Background

The numerical control lathe tool is a tool mainly applied to a numerical control lathe, can process end faces, excircles, inner holes, threads, grooving, cutting-off and the like, is used for processing end face center holes of shaft or rod parts, can use tips on the numerical control lathe to prop against the processed center holes, improves the clamping stability of the parts when the outer circles are turned, is also beneficial to guiding a drill bit when drilling, and can prevent deflection of the holes. In order to meet various cutting functions, various excircle turning tools, inner hole turning tools, threading tools, cutting off turning tools, forming turning tools, drill bits, center drills and the like are required to be clamped on the tool rest, the operation of complex numerical control programs can be completed through automatic tool replacement in the one-time clamping process of parts, and the requirements of the machining size and the form and position tolerance of the parts can be met. In some parts machining processes, multiple cutters are required to be used simultaneously, so that the cutter position on the cutter rest is insufficient, the cutters are required to be replaced after machining is stopped, and the production efficiency is reduced. According to the practical experience of the numerical control lathe tool in the production process, the numerical control lathe tool with the center drill structure is designed, a hole matched with the center drill outer circle can be machined on the self-made numerical control lathe tool, the center drill is installed, the functions of end face turning, end face center hole drilling and outer circle turning are achieved through the numerical control lathe tool at the same time, the tool bit of the tool rest installation center drill is saved, the tool bit and the drill bit are used for installing an inner hole lathe tool and the drill bit, and the numerical control program is prevented from being stopped to increase the center drill in the machining process. The self-made numerical control turning tool with the center drill is used in actual production, has a good effect and is worthy of popularization and application.

Disclosure of Invention

The utility model relates to a self-made numerical control turning tool with a center drill, which is characterized in that: the central drill can be installed, the central drill is fixed in a set screw pushing structure, and the extension length of the central drill can be adjusted; the distance from a hole drilled in a machining center on a self-made numerical control turning tool to the tip of a blade can be set according to the diameter size of a machined part, so that the machining range is wide; the structure and the manufacturing method are simple, can simultaneously finish end face turning, end face center hole drilling and excircle turning, and are suitable for processing slender shaft parts.

In order to ensure smooth cutting processing and obtain a processing surface meeting the requirements, the turning part and the drilling part of the designed numerical control lathe tool must have reasonable geometric shapes and sizes so as to prevent use interference. The numerical control lathe tool adopts an excircle lathe tool with a main deflection angle of 95 degrees, so that the end face of a shaft part or a rod part can be machined, and the excircle can be machined; the distance from the center of a hole drilled in the machining installation center to the tool tip of the blade is 30mm to 50mm, so that the rigidity of the numerical control turning tool can be ensured, the turning efficiency is improved, the machining range is increased, and the maximum diameter of a machined shaft part can reach 80mm; when the center drill is installed, the distance from the drill bit to the cutter point of the cutter blade is 15mm, so that the conventional center hole size requirement can be met, the use stability of the center drill can be improved, the drilling efficiency can be improved, and the distance from the drill bit to the cutter point of the cutter blade can be reasonably adjusted according to the specification and the size of the center drill and the size requirement of the center hole.
