Abstract
The invention relates to a processing cutter for differential cutting of combined holes of reinforced fiber composite materials. The processing cutter comprises a main cutter, a differential cutter and a differential, the main cutter and the differential cutter are coaxial, the main cutter is a hole processing cutter, the differential cutter is a tubular cutter, the processing cutter for the combined holes is driven by the differential, an output shaft I and an output shaft II of the differential are coaxial, the output shaft II of the differential is connected with the main cutter, and the output shaft I of the differential is connected with the differential cutter. The main cutter is an internal cutter and has the function of removing most of processing allowance, the differential cutter is an external cutter, fibers are drawn out by the internal cutter, at the moment, the fibers are cut off by the external cutter due to differential rotation of the external cutter and the internal cutter when the main cutter works, so that normal cutting is realized, and a processed surface is smooth. In addition, the quality of the processed surface of a hole of a reinforced fiber composite material is improved by the aid of the processing cutter. Besides, the processing cutter is reasonable in design, simple in structure and convenient in utilization and operation.
Description
Technical field
The invention belongs to the tool for cutting machining technical field, be specifically related to the aperture knife tool of machining boreholes.
Background technology
The cutter of existing machining boreholes comprises fluted drill, reamer, counterbit, reamer, cylindrical drill, depth drill and composite holes process tool etc.During with these cutter machining holes, principal cutting movement is the rotation (or rotation of workpiece) of cutter, and feed motion is that the straight line of cutter moves.When some difficult-to-machine material of processing, attached supersonic vibration in the cutting movement of cutter (or workpiece) is to reduce cutting force, chip breaking or to improve crudy and stock-removing efficiency.During machining hole, existing aperture knife tool possibly pulled out fiber when cut on having fortifying fibre composite material work piece 7, and the surface in the hole 8 after the processing stays fiber (burr) 9, sees Fig. 4.Cutting can not normally be carried out or owing to hole surperficial crude do not reach the crudy requirement.
Summary of the invention
For the problem that exists in the hole processing that solves the fortifying fibre composite, the present invention provides a kind of differential cutting combination bore process tool that is used for the fortifying fibre composite.
Concrete technical scheme of the present invention is following:
Differential cutting combination bore process tool is made up of inside and outside two cutters.Interior cutter is that the output shaft II of main cutting cutter and differential mechanism links; Under its transmission, accomplish the function of removing most of allowance, it possibly pull out the fiber in the composite in working angles, at this simultaneously; Because outer cutter and differential mechanism output shaft I link; Under its transmission, with interior cutter differential rotation, pull out the instantaneous of fiber at interior cutter, outer cutter cuts off the purpose of fiber to realize normally cutting and make finished surface smooth.Realize that inside and outside cutter differential rotates available differential mechanism or other mechanisms realize.
Useful technique effect of the present invention is embodied in following two aspects:
1. the present invention possesses coaxial inside and outside two cutters, and interior cutter is the main cutting cutter, accomplishes the function of removing most of allowance; It possibly pull out the fiber in the composite in working angles, at this simultaneously, because outer cutter and the rotation of interior cutter differential; Pull out the instantaneous of fiber at interior cutter; Outer cutter cuts off fiber to realize normal cutting, makes finished surface smooth, uses the present invention to improve the surface quality of fortifying fibre composite hole processing.
2. the present invention is reasonable in design, and is simple in structure, uses easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the fluted drill structural representation for the main cutting cutter.
Fig. 3 is the cylindrical drill structural representation for the main cutting cutter.
Fig. 4 is having the sketch map behind the machining hole on the fortifying fibre composite for adopting existing aperture knife tool.
Sequence number among the last figure: machine tool chief axis 1, differential mechanism 2, II output shaft 3, I output shaft 4, outer cutter 5, main cutting cutter 6, the fiber (burr) 9 that has fortifying fibre composite material work piece 7, hole 8, pulls out.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further through embodiment.
Embodiment 1:
Referring to Fig. 1 and Fig. 2, the differential cutting combination bore process tool that is used for the fortifying fibre composite comprises main cutting cutter 6, differential cutter and differential mechanism 2, and main cutting cutter 6 is a fluted drill, and the differential cutter is outer cutter 5, and is as shown in Figure 2; Differential mechanism 2 is a gear differential mechanism.The I output shaft 4 and the II output shaft 3 of differential mechanism 2 are coaxial; The I output shaft of differential mechanism 2 is connecting main cutting cutter 6, and the II output shaft of differential mechanism 2 is connecting outer cutter 5, and outer cutter 5 draws the cutter tool for tubulose.
During use, the input of differential mechanism 2 is installed on the machine tool chief axis 1, sees Fig. 1.In the time of Twist Drill, tubulose draws the cutter tool in the same way or reverse rotation, and rotary speed is higher or lower than fluted drill, and feed speed synchronously or differential.Tubulose draws the cutter tool in the function of accomplishing certain excision surplus, to realize cutting off the effect of the fiber of being pulled out by fluted drill.
Embodiment 2:
Referring to Fig. 1 and Fig. 3, said main cutting cutter 6 is a cylindrical drill, and outer cutter 5 is the tubulose cutting tool.
In the time of the cylindrical drill trepanning; The tubulose cutting tool in the same way or reverse rotation; Rotary speed is higher or lower than cylindrical drill, the synchronous or differential of feed speed, and the tubulose cutting tool realizes cutting off the effect that ticking bores the fiber of pulling out in the function of accomplishing certain excision surplus.
