Description
Technical field
The present invention relates to field of machining, particularly a kind of telescopic boring cutter that can be used for inner conical surface in machining hole.
Background technology
The inner conical surface of 2 × 15 ° processing one under the aperture of part is needed in the process of certain part, because volume of part is comparatively large and profile is irregular, if process this inner conical surface on boring machine, need to carry out installation centering to workpiece before processing, to ensure the machining accuracy of inner conical surface, cause the installation of every part workpiece all to need the time of at substantial, working (machining) efficiency is low; If process on upright drill, then the inner conical surface quality in hole is difficult to again ensure.
Summary of the invention
The object of the invention is to solve above technical problem, provide a kind of can the scalable boring cutter of inner conical surface in processing work hole on upright drill quickly and easily.
For solving the problems of the technologies described above, present invention employs a kind of scalable inner conical surface processing boring cutter, comprise handle of a knife and knife bar, described knife bar is enclosed within handle of a knife, connected by connecting pin between described knife bar and handle of a knife, described handle of a knife is provided with upper locking nut, described knife bar is provided with lower locking nut, movable blade block is provided with in described knife bar, described movable blade block is installed with movable blades, described movable blade block is flexibly connected by bearing pin with between knife bar, spring is provided with between described knife bar and movable blade block, described spring one end withstands movable blade block, the other end withstands in the adjustment screw that is fixedly mounted on knife bar, described handle of a knife tail end is provided with inclined-plane, described movable blade block is provided with the inclined-plane matched with handle of a knife tail end inclined-plane.
Further, in the present invention, described knife bar lower end is installed with location bulb.
The beneficial effect that the present invention has: by the setting of telescopic movable cutter head, quickly and easily boring cutter can be arranged on processing drilling machine completing inner conical surface in hole, working (machining) efficiency is high, the uniformity of inner conical surface processing is good, effectively can ensure machining accuracy, and the overhang of adjustable activity cutter head controls machining amount, further ensures the crudy of internal taper hole.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1, for one scalable inner conical surface processing boring cutter, comprise handle of a knife 1 and knife bar 5, described knife bar 5 is enclosed within handle of a knife 1, connected by connecting pin 3 between described knife bar 5 and handle of a knife 1, described handle of a knife 1 is provided with upper locking nut 2, described knife bar 5 is provided with lower locking nut 4, movable blade block 11 is provided with in described knife bar 5, described movable blade block 11 is installed with movable blades 6, described movable blade block 11 is flexibly connected by bearing pin 7 with between knife bar 5, spring 9 is provided with between described knife bar 5 and movable blade block 11, movable blade block 11 is withstood in described spring 9 one end, the other end withstands in the adjustment screw 8 that is fixedly mounted on knife bar 5, described handle of a knife 1 tail end is provided with inclined-plane 13, described movable blade block 11 is provided with the inclined-plane 14 matched with handle of a knife tail end inclined-plane 13.
In the present invention, described knife bar 5 lower end is installed with location bulb 10.
This boring cutter forms primarily of handle of a knife 1 and movable cutter head 6, and handle of a knife 1 matches with the mohs tapered bore of vertical drilling spindle, and knife bar 5 is rotated in company with handle of a knife 1 together by connecting pin 3, and can move up and down along handle of a knife 1.Movable blade block 11 embeds in knife bar body groove, and connects with bearing pin 7, and movable blade block 11 can swing around bearing pin 7.Before machining, movable blade block 11, under the effect of spring 9, tightens in knife bar 5 groove, and the pressure of spring 9 suitably can be adjusted by adjustment screw 8.When machining, owing to being subject to cutter, the oblique prone thrust of 1 tail end, forces the movable cutter head 6 be arranged on movable blade block 11 to stretch out knife bar 5, carries out the machining of inner conical surface.By adjusting the position of upper and lower locking nut 2,4, the overhang of control activity cutter head 6.The location bulb 10 of knife bar 5 end face contacts with the conical surface bottom workpiece 14 hole, plays axial, radial positioning action.
Add man-hour, first make knife bar 5 decline with vertical drill main shaft handle of a knife 1, and enter in blind hole that workpiece 12 has been processed, until the location bulb 10 of knife bar 5 end contacts with the blind via bottom conical surface.Make handle of a knife 1 continue to decline, until handle of a knife 1 tail end inclined-plane 13 is pressed against on the inclined-plane 14 of movable blade block 11, compressing activity cutter head 6 is protruding, machining inner conical surface.Now lower locking nut 4 controls the position that handle of a knife 1 declines, i.e. the overhang of control activity cutter head 6, ensures the crudy of inner conical surface.
After processing, handle of a knife 1 rises, and handle of a knife 1 inclined-plane leaves movable blade block 11 inclined-plane, and now then movable blade block 11, under the thrust of spring 9, rotates around bearing pin 7, is retracted in knife bar 5 groove.Along with handle of a knife 1 continues to rise, connecting pin 3 contacts with upper locking nut 2, and with cutter, 5 rise together, leave workpiece 12, thus complete the processing of inner conical surface.
