Coaxial double-blade cutter inclined-insertion machining tool and machining method

Abstract

The invention discloses a coaxial double-blade cutter inclined-insertion machining tool and a machining method. The coaxial double-blade cutter inclined-insertion machining tool is composed of a toolbody, a double-edge cutter, wherein the tool body is composed of a base, a tailstock and a dividing head, the tailstock is arranged at the left end of the top surface of the base, the dividing head isarranged at the right end of the top surface of the base, a workpiece is clamped between the tailstock and the dividing head, the double-blade cutter for milling groove is arranged above the workpiece, the double-blade cutter is composed of a clamping part, a connecting part and a cutting body, the bottom end of the clamping part is provided with the connecting part, the center of the bottom endof the connecting part is provided with the cutting body, reinforcing ribs are arranged at the top ends and the bottom ends of the outer walls at the two sides of the cutting body, the end part of oneend of the cutting body is of a circular-angle cutting edge, and the end part of the other end of the cutting body is of a right-angle cutting edge. According to the tool, the structure is simple, the operation process is reduced during machining and production, the processing efficiency is effectively improved, the quality is ensured, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal cutting and processing, and in particular relates to a coaxial double-edged cutter oblique insertion processing tool and a processing method. Background technique [0002] The part is made of integral aluminum alloy and has a complex structure. The groove structure on the part is about 5mm wide and 70mm deep. It is difficult to process with an undercut surface and an inclined surface that needs to be cleaned. Then use a diameter of 5 to lengthen the end mill L= 150 rough and fine milling groove bottom inclined side edge processing, and then use diameter 5 short end mill L=65 fine milling groove upper inclined positioning surface bottom edge processing, this processing method mainly has the following problems: 1. High requirements for machine tools, The processing equipment used must be a five-axis machining center, and the equipment investment is large; 2. There are requirements for the swing of the...

Problems solved by technology

[0002] The part is made of integral aluminum alloy and has a complex structure. The groove structure on the part is about 5mm wide and 70mm deep. It is difficult to process with an undercut surface and an inclined surface that needs to be cleaned. Then use a diameter of 5 to lengthen the end mill L= 150 rough and fine milling groove bottom inclined side edge processing, and then use diameter 5 short end mill L=65 fine milling groove upper inclined positioning surface bottom edge processing, this processing method mainly has the following problems: 1. High requirements for machine tools, The processing equipment used must be a five-axis machining center, and the equipment investment is large; 2. There are requirements for the swing of the machine tool, and the machine tool with a small swing is prone to overtravel alarms during processing; 3. The workpiece clamping should take into account the swing axis of the machine tool Otherwise, there will be interference between the machine tool spindle and the worktable, or the workpiece shape and inner groove cannot be clamped and processed at one time; 4. When the workpiece is processed on a five-axis machine tool, only one end can be fixed. Poor clamping rigidity; 5. There are requirements for the strength, sharpness and length of the extended milling cutter, and the tool price is high; 6. When machining the inclined surface of the groove bottom, the processing efficiency is low and the processing quality is poor due to the influence of the tool itself.
