Abstract
The invention discloses a compound tool applicable to high-speed and accurate holing on an aircraft panel. The compound tool is provided with a double-helical side edge, the helical angle of the side edge is 30-40 degrees, a bottom edge is divided into three sections, i.e., a chisel edge, rough machining edges and finish machining edges; the included angle of the two rough machining edges is 120-150 degrees, and the included angle of the two finish machining edges is 60-65 degrees; a dimpling edge is connected with the helical side edge; and after holes are drilled through, the tool is fed continuously, and the dimple machining is finished by utilizing the dimpling edge. The compound tool disclosed by the invention has the advantages that the hole drilling, hole reaming and dimpling can be finished once without need of tool change, and the roughness of the machining surfaces of the holes reaches Ra1.6.
Description
Technical field
The invention belongs to aircraft mounting technology field, relate to a kind of compound tool that is applicable to the at a high speed accurate drilling of aircraft target ship.
Background technology
Aircraft is to be formed by connecting through securing member a large amount of parts.In order to adopt securing member to connect parts, must drilling on airplane component.The hole of securing member requires surface roughness low on the aircraft, and precision is high.And, reduce air drag in order to guarantee the aircraft smooth outer surface, and the fastener hole on fuselage, wing exterior skin surface requires after boring, must carry out counter boring, and after securing member inserted connecting hole, ailhead was concordant with skin-surface.In order to reach the required precision of securing member connecting hole, the technology that adopts at present is with the first hole of bit drills, uses the reaming of major diameter drill bit then; The reamer fraising that increases successively with a series of diameters again; The ream consumption of every cutter is about 0.5mm, and each connecting hole will could be accomplished through repeatedly processing like this, and needs a large amount of cutter and process time; Efficient is low, and the precision influence factor is many.In addition, adopt existing technology, after connecting hole processing reaches the diameter requirement, also will carry out counter boring separately, further increased the cutter consumption, reduced efficient.Because connecting hole is a separate machined with the awl nest, influenced the coaxial precision of hole again with the awl nest.Adopt the accurate drilling compound tool of high speed of the present invention disposable realization to have brill, hinge, counter boring processing in the technology now, improved hole surface precision and working (machining) efficiency, reduced number of cutters, improved economic benefit.And this cutter retaining part has a step surface, the position that this step surface can aligned cutting tool ream sword, thus guaranteed the degree of depth of counter boring.So,, need not for the position of confirming the ream sword to confirm again cutter zero point further to have improved working (machining) efficiency because tool damage need change new cutter the time, can directly process.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of compound tool that is applicable to the at a high speed accurate drilling of aircraft target ship is provided.
This compound tool has double helix side edge, helical angle, chisel edge, roughing sword, fine finishining sword, ream sword, knuckle, tool shank, step locating surface;
This compound tool body one end is provided with ream sword, double helix side edge, shear blade in order; The helical angle of double helix side edge is 30～40 °; Shear blade is divided into three sections of chisel edge, roughing sword and fine finishining swords; Angle between two roughing swords is 120～150 °, and the angle between two fine finishining swords is 60～65 °, and double helix side edge and ream sword are provided with knuckle; The compound tool body other end is provided with step locating surface, tool shank.
The present invention compared with prior art, the beneficial effect that has:
1) the accurate drilling compound tool of high speed of the present invention can disposable realization have brill, hinge, counter boring processing in the technology now, has improved the axiality and the working (machining) efficiency of hole surface precision, hole and awl nest, and has reduced the cutter consumption, has improved economic benefit.
2) the hole surface roughness that processes of the disposable brill of the accurate drilling compound tool of high speed of the present invention, hinge, counter boring reaches Ra1.6, is higher than the drilling quality of universal cutter far away.
3) the accurate drilling compound tool of high speed of the present invention shank has a step surface, the position that this step surface can aligned cutting tool ream sword, thus guaranteed the degree of depth of counter boring.So,, need not for the position of confirming the ream sword to confirm again cutter zero point further to have improved working (machining) efficiency because tool damage need change new cutter the time, can directly process.
