Abstract
The utility mode provides a reamer for machining a sandwich structure of titanium alloy and aluminum alloy. The reamer for machining the sandwich structure of titanium alloy and aluminum alloy comprises a reamer front guide, a reamer edge part, a reamer rear guide and a reamer handle part, wherein the front angle of a cutting edge on the reamer edge part is 3-5 degrees, the rear angle of the cutting edge is 13-15 degrees, the helical angle is 3-5 degrees, and the angle of the cross section of a chip pocket of the reamer is 85-90 degrees. The reamer for machining the sandwich structure of titanium alloy and aluminum alloy promotes machining quality and efficiency of reaming of assembly holes in the sandwich structure of titanium alloy and aluminum alloy and avoids scratches in the machining process of aluminum alloy holes.
Description
Technical field
The utility model relates to a kind of reamer, is used for the fraising processing of titanium alloy and aluminum alloy interlayer structure.
Background technology
Titanium alloy and aluminum alloy interlayer structure are used in the aeroplane structure design more and more widely, but because machining titanium alloy and aluminum alloy interlayer structure reamer main structure parameters design are unreasonable, caused existing machining titanium alloy and aluminum alloy interlayer structure in the fraising process, often to produce easily the phenomenon that aluminum alloy surface scratches.It is in particular in: the numerical value of anterior angle and helical angle is 0 °, so that cutting edge is not sharp, produces easily the bits knurl; The angle of cutter chip pocket cross section is too little, and its numerical value is 80 °, causes easily chip space not enough.The problems referred to above have finally had a strong impact on precision and the efficient of aircraft assembling processing, and are difficult to satisfy the requirement of aircraft assembling processing.
The utility model content
The purpose of this utility model provides the reamer of a kind of machining titanium alloy and aluminum alloy interlayer structure, has improved quality and the efficient of titanium alloy and aluminum alloy interlayer Standard hole fraising processing, has avoided the scuffing of aluminium alloy hole work in-process.
The technical solution of the utility model: the reamer of a kind of machining titanium alloy and aluminum alloy interlayer structure, guide and the reamer shank after comprising the front guiding of reamer, reamer blade, reamer, cutting edge anterior angle on the reamer blade is 3 °～5 °, the cutting edge relief angle is 13 °～15 °, helical angle is 3 °～5 °, and the angle of reamer chip pocket cross section is 85 °～90 °.
The beneficial effects of the utility model: the utility model is by the main structure parameters redesign to machining titanium alloy and aluminum alloy interlayer structure reamer, the cutting edge anterior angle that is about to reamer strengthens, make 3 °～5 °, reamer cutting edge helical angle is strengthened, make 3 °～5 °, and the angle of reamer chip pocket cross section strengthened, make 85 °～90 °, so that the fraising processing effect of reamer is better, being difficult for producing the aluminium alloy hole scratches, thereby improved quality and the efficient of titanium alloy and the fraising processing of aluminum alloy interlayer Standard hole, avoided the scuffing of aluminium alloy hole work in-process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the machining titanium alloy take the cutting edge diameter as 10mm and aluminum alloy interlayer structure reamer are example, and it comprises before the reamer guiding 3 and reamer shank 4 behind guiding 1, reamer blade 2, the reamer.Wherein, the diameter of guiding 1 before the reamer is made 9.9mm, the cutting edge diameter is made 10mm, cutting edge length is made 15mm, guiding 3 diameters behind the reamer are made 13mm, the cutting edge anterior angle 6 on the reamer blade 2 is made 3 °～5 °, the cutting edge relief angle is made 13 °～15 °, cutting edge helical angle 5 is made 3 °～5 °, the angle 6 of reamer chip pocket cross section is made 85 °～90 °.
