Summary of the invention
The utility model object is to provide for present technology above shortcomings a kind of device and method of convenient, fast, practical, flexible, changeable removal hole inward flange burr.
The technical solution of the utility model is: a kind of device of removing hole inward flange burr, and knife bar rear end is fixed on for driving the knife rest that revolves of knife bar rotation; Knife bar front end is fixed with the tulwar head of removing hole to be processed inward flange burr with knife bar rotation; On tulwar head, have cutting edge with inward flange contact position, hole to be processed; On knife bar, be set with the positioning seat that can slide along knife bar; Knife bar pilot hole internal diameter for plug-in mounting knife bar on positioning seat equates with knife bar external diameter;
Described positioning seat is that described positioning seat small stair portion external diameter equates with hole to be processed internal diameter for coordinate the step-like structure of location with hole to be processed; On the central axis of described positioning seat small stair portion and positioning seat, the central axis of knife bar pilot hole is positioned at same straight line;
Positioning seat and revolve on the knife bar between knife rest and be set with for promoting positioning seat and be installed in hole to be processed and make curved cutter edge place be close to the spring of hole to be processed inward flange.
Described spring rear end be loaded on the spring base revolving on knife rest and offset.
End in contact after positioning seat front end and tulwar head under described spring elongation state.
A kind of method of using the device removal hole inward flange burr of removing hole inward flange burr:
1) promote positioning seat motion compresses spring backward, knife bar center axis deviation hole to be processed central axis is stretched into knife bar front end tulwar head in hole to be processed;
2) mobile knife bar makes knife bar central axis and hole to be processed central axes, retracting spring, and spring elongation promotion positioning seat travels forward makes positioning seat small stair portion be installed in hole to be processed, curved cutter edge is close to hole to be processed inward flange;
3) revolving knife rest makes knife bar drive the rotation of tulwar head to remove hole to be processed inward flange burr.
The utility model is owing to taking above technical scheme, and it has the following advantages: 1, the hole inward flange burr of machining hole is removed clean, thorough; 2, convenient to operation, efficiency is high, with low cost; 3, highly versatile, only needs to change modular construction size, to the hole inward flange burr of different machining holes, all can adopt same method to remove.
The utility model can obviously improve the hole inward flange quality of machining hole, and efficiency is high, can eradicate adverse effect or even serious harm that machining hole inward flange burr brings subsequent applications, and the generation of minimizing accident, has obvious economic benefit and social benefit.

The specific embodiment
In Fig. 1, knife bar 4 rear ends are fixed on and are revolved knife rest 6 for what drive knife bar 4 rotation, knife bar 4 front ends are fixed with the tulwar head 1 of removing hole to be processed 8 inward flange burrs with knife bar 4 rotations, on tulwar head 1, have cutting edge with 8 inward flange contact positions, hole to be processed, on knife bar 4, be set with the positioning seat 2 that can slide along knife bar 4, the knife bar pilot hole internal diameter for plug-in mounting knife bar 4 on positioning seat 2 equates with knife bar 4 external diameters.Positioning seat 2 is step-like structure, and positioning seat 2 small stair portion external diameters equate with hole to be processed 8 internal diameters.On the central axis of positioning seat 2 small stair portions and positioning seat 2, the central axis of knife bar pilot hole is positioned at same straight line.Positioning seat 2 and revolve on the knife bar 4 between knife rest 6 and be set with for promoting positioning seat 2 and be installed in hole 8 to be processed and make tulwar head 1 cutting edge place be close to the spring (Compress Spring) 3 of hole to be processed 8 inward flanges.Tulwar head (special cutter) 1 forms integral body with knife bar 4 by welding, spring base 5 with revolve knife rest 6 and form integral body by welding.Knife bar 4 is through positioning seat 2, Compress Spring 3 and revolve knife rest 6, with screw 7 by knife bar 4 with revolve knife rest 6 and fix.
In Fig. 2,8 is hole to be processed, and 9 for treating the hole inward flange burr in work hole.
When the utility model is used, comprise the following steps: the machining hole that 1) tulwar head bias is pushed to inward flange burr; 2) tulwar head and machining hole are carried out to coaxial positioning; 3) rotation tulwar head, removes hole inward flange burr.Concrete operations are: by positioning seat 2 with revolve knife rest 6 use hands reinforcing Compress Springs 3, make tulwar head 1 bias enter machining hole (as Fig. 3).Make tulwar head and machining hole carry out coaxial positioning schematic diagram (as Fig. 4).By the strength of hand, revolve knife rest 6, tulwar head 1, with revolving knife rest 6 rotations, utilizes the elastic force of spring 3 that the hole inward flange burr of machining hole is removed.Revolve knife rest 6 rotation and the hole inward flange burr of workpiece can be removed to clean (as Fig. 5) in two weeks.According to different machining holes, can select different tulwar heads and different springs.
Tulwar head 1 is for removing hole inward flange burr 9.Positioning seat 2 is for carrying out coaxial positioning to machining hole 8 and tulwar head 1.Knife bar 4 is for connecting bending cutter head 1 and revolve knife rest 6, has the effect of transmitting torsion and setting up spring force simultaneously.Revolve knife rest 6 and facilitate manual operation, laborsaving, flexible, simultaneously for knife bar 4 is carried out to tightening.Compress Spring 3 is removed the dynamics of hole inward flange burr 9 for setting up tulwar head 1, press and press positioning seat 2, can facilitate tulwar head 1 bias to enter machining hole 8 after making spring compressed.
