Description
Technical field
The utility model belongs to the technical field of mechanical cutting tool, and in particular to a kind of to be adapted to what casting technique was formed
The instrument that bent hole is polished.
Background technology
Occur in by the hydraulic part by casting technique production, the cooling part such as motor case and hydraulic motor
Bent hole, such as bend oilhole, motor Cooling Holes.Due to having casting slag, knob and part caused by casting process inside hole
Caused casting film, the flow velocity of hydraulic pressure product component working can be influenceed, unsafe factor is caused to aviation parts.
The debris generally use air-blowing liquid such as knob, casting slag, casting film, casting ash is clear caused by casting in existing bent hole
The method washed makes it come off.It may be such that product rejection processing does not use if any what debris big in hole can't was washed off clearly, so as to make
Do not wash clean into substantial amounts of product rejection and clearly.Notification number is CN103949588B, entitled " thin in a kind of aluminium alloy castings
The invention of the manufacturing process of long bending irregularly-shaped hole " provides a kind of accurate casting of aluminium alloy castings with elongate curved irregularly-shaped hole
Manufacturing process is made, is to be triggered from the angle for how ensureing the qualified shaping of aluminium alloy castings elongate curved irregularly-shaped hole, stresses irregularly-shaped hole
Sophisticated design to improve the dimensional accuracy of aluminium alloy castings elongate curved irregularly-shaped hole, surface roughness, wear resistance and corrosion resistance and make
Use intensity.But the shortcomings that this method is that cost is higher, since it is desired that being designed accordingly for different products.
Utility model content
For the deficiency of prior art, the utility model provides a kind of bent hole milling tools, to the debris in curved, curved hole
Effectively removed, it is clean smooth in retaining hole, so as to reduce scrapping for product.
To achieve the above object, the technical solution adopted in the utility model is a kind of bent hole milling tools, and it includes soft
Property driving handle, the soft drive handle side connects grinding head, and opposite side connection drive device, grinding head is together with soft drive handle
It can enter in the bent hole of part to be processed, drive device driving soft drive handle, soft drive grip strip moves grinding head motion,
Debris in bent hole is purged.
Further, preferably, above-mentioned soft drive handle is steel wire spiral handle.
Further, above-mentioned grinding head is not put the first edge on a knife or a pair of scissors using the put the first edge on a knife or a pair of scissors head of grinding head or alloy of the head of alloy and is had abrasive material to beat
Bistrique.
Preferably, the head grinding head of above-mentioned steel wire spiral handle and alloy is welded to connect by metal shaft.
Realized using the rotary orientation of steel wire spiral shank and the tangent of grinding head blade and the traditional method of indicating the pronunciation of a Chinese character in rotary course
Automatically move forward and backward.
Compared with prior art, in the technical solution of the utility model, because bent hole milling tools includes soft drive
Handle, soft drive handle connection grinding head, grinding head enter in curved, curved hole together with soft drive handle, drive soft drive handle, flexible
Driving handle drives grinding head motion, and the debris in curved, curved hole is effectively removed, clean smooth in retaining hole, completely solution
The cleaning work of debris in certainly curved, curved hole, effectively reduces scrapping for product.
Brief description of the drawings
Fig. 1 is the utility model bent hole milling tools schematic diagram；
Fig. 2 is this bent hole milling tools course of work schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, the utility model proposes a kind of bent hole milling tools include soft drive handle 1, it is flexible
Driving handle 1 connects grinding head 2, soft drive handle connection drive device 3, and grinding head can enter together with soft drive handle 1 and be added
In the curved of work part 4, curved hole 5, soft drive handle is driven, soft drive grip strip moves grinding head motion, to the debris in curved, curved hole
Effectively removed, it is clean smooth in retaining hole, the cleaning work of debris 6 in curved, curved hole is fully solved, effectively reduces production
Product are scrapped.
Soft drive handle uses steel wire elastic helix handle (flexible axle), grinding head using the head of alloy put the first edge on a knife or a pair of scissors grinding head or
The head plating abrasive material of steel alloy does not put the first edge on a knife or a pair of scissors grinding head, and the head grinding head of steel wire elastic helix handle (flexible axle) and alloy passes through metal
It is welded to connect, the head grinding head of steel wire elastic helix handle (flexible axle) and alloy is welded to connect by metal, improves connection
Stability and the rigidity for transmitting moment of torsion.
Moment of torsion can preferably be transmitted using steel wire elastic helix handle (flexible axle), steel wire elastic helix handle (flexible axle) utilizes copper
The head of the method welding carbide rotary tool of weldering can solve the problems, such as knob casting slag of polishing completely, and realize product
Grinding head head and shank it is concentric；The rotary orientation of steel wire shank is recycled to be realized with the tangent of grinding head blade and the traditional method of indicating the pronunciation of a Chinese character
Moving forward and backward automatically in rotary course：I.e. left-handed handle welding left cut head being reversed in bent hole using hand-operated electric drill
Automatic cutting of advancing is realized in cutting.Recycling the diameter on head to be less than 0.2 millimeter of aperture just can smoothly enter bent hole work.Through
All knobs casting slag is all reamed by rotary cutting after crossing rotation processing, in hole discharges as chip.
The utility model has the advantages that fully achieving the removal of residual substance in hole, can also be processed according to the positioning of endoscope
The effect quickly cut and quickly discharged is realized afterwards, and this method can also be utilized only to make the instrument that end sword circumference does not put the first edge on a knife or a pair of scissors and do not hinder hole wall
The only effect of processing knob casting slag, is fully solved the cleaning work of bent hole.
In above-described embodiment, soft drive handle uses the soft handle of elastic wire spiral, and grinding head is put the first edge on a knife or a pair of scissors using the head of alloy
The head of grinding head or steel alloy plating abrasive material does not put the first edge on a knife or a pair of scissors grinding head, and soft drive handle can also use flexibility to transmit moment of torsion
Flexible axle, grinding head can also use common grinding tool and file etc. to be used as grinding head, as long as with the soft of flexible
Property driving handle connection grinding head, the removing of debris in curved, curved hole is realized in the driving grinding head motion of soft drive handle, but this reality
With new protection domain.
Schematically the utility model and embodiments thereof are described above, this describes no restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So if this area
Those of ordinary skill enlightened by it, in the case where not departing from this creation objective, without creativeness design and the technology
The similar frame mode of scheme and embodiment, all should belong to the scope of protection of the utility model.
