Abstract
The utility model discloses a boring tool capable of making the inside and outside diameter floating synchronously, which solves the problems of the prior art that the inside diameter floating boring tool is difficult to be use in the large workpiece, the outside diameter process adopting the light blade cutting method has the defects of low efficiency, easy scrap and larger loss. The utility model is characterized in that a floating cutter beam is arranged in the square holes of a cutter body and a cutter cavity, the left and the right ends of the floating cutter beam are respectively provided with a left and a right cutter arm, the lower ends of the left and the right cutter arms are provided with an outside diameter cutter, and the lower end of the cutter pants is provided with an inside diameter cutter. The utility model has the advantages that the inside diameter and the outside diameter can automatically carry out centering, the finishing of the inside diameter and the outside diameter can be finished simultaneously, and the device is particularly suitable for the processing of the larger workpiece, the off-center workpiece and the high precision requirement workpiece.
Description
The utility model belongs to a kind of cutter that is used for vertical lathe and engine lathe, particularly a kind of interior synchronous floating boring tool of external diameter.
In machining; Some workpiece needs the interior external diameter fine finishining of the fine finishining of inside and outside footpath, particularly large-scale workpiece, and quality requirement is all very high.In the prior art, a kind of internal diameter floating boring tool is arranged, utilize workpiece endoporus chipping allowance spacing, make cutter do trace and move, reach the centering effect, finish working angles.But existing internal diameter floating boring tool is used relatively difficulty on big workpiece, be difficult for grasping.For external diameter processing, prior art generally all is to adopt the finishing tool cutting process, this method, and inefficiency, labour intensity is big, occurs waste product easily, loses bigger.
The purpose of this utility model is to solve weak point in the prior art, a kind of interior external diameter floating boring tool is provided, realization internal diameter and external diameter can both be felt relieved, the fine finishining of external diameter in can finishing simultaneously, be particularly useful for relatively large workpiece and eccentric work piece, and the processing of the high workpiece of required precision, guarantee crudy, increase work efficiency and reduce labour intensity.
The utility model is that a floating knife beam is installed in the square hole between cutter hub and cutter trousers, be separately installed with left tool arm and right tool arm at the two ends, the left and right sides of floating knife beam, in the lower end of left tool arm and right tool arm the external diameter cutter is installed, lower end at the cutter trousers is equipped with the internal diameter cutter by knife bar, in process, after adjusting inside/outside diameter size, internal diameter cutter and external diameter cutter can self-centerings, and the radial cutting force by being produced in the working angles, the purpose that external diameter floats and cuts in realizing.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
Accompanying drawing 1 is a front view of the present utility model; Accompanying drawing 2 is vertical views of the present utility model.
As shown in drawings, the utility model has a cutter hub 2 that is connected with lathe cutter platform, mill out a locating slot in the middle of the said cutter hub 2, a floating knife beam 3 is installed in the middle of locating slot, at the opening direction of cutter hub 2 locating slots a upper end being installed is the plane, the middle part, lower end has the cutter trousers 7 of taper hole, make between the last plane of the locating slot of cutter hub 2 and cutter trousers 7 and form a floating knife beam location square hole, guarantee that floating knife beam 3 normally moves in this location square hole, fastening between cutter hub 2 and the cutter trousers 7 with screw, two ends, the left and right sides at floating knife beam 3, connecting left tool arm 4 and right tool arm 1 with soket head cap screw 5 respectively, in the cutter groove of the lower end of left tool arm 4 and right tool arm 1, external diameter cutter 6 is installed respectively, in the taper hole of the lower end of said cutter trousers 7, knife bar 9 is installed and compresses with knife bar gland 12; Fastening between knife bar 9 and the knife bar gland 12 with screw 8.In the cutter groove of the lower end of knife bar 9, internal diameter cutter 10 is installed, is connected with gland 11 with soket head cap screw, make to form a knife bar location square hole between knife bar 9 and the cutter depression bar 11, guarantee that the internal diameter cutter normally floats in this knife bar location square hole in the lower end of knife bar 9.
When interior external diameter floats fine finishining synchronously, earlier choose corresponding floating knife beam 3 according to workpiece external diameter size, again external diameter floating tooling 6 is adjusted with treating the external diameter of finish turning workpiece, then internal diameter floating tooling 10 is packed into and adjust in the knife bar 9, can carry out the synchronous finish turning of internal diameter and external diameter.
The utility model has the advantage of, owing to feel relieved automatically in inside and outside footpath, float synchronously, thereby smart car quality is good, particularly to the workpiece of batch machining, after once adjusting tool dimension, can process batch workpiece continuously, thereby high efficiency, needs according to the workpiece size requirement, as only needing a kind of processing, such as machining hole or processing excircles, only need pull down corresponding accessory and can use.
Claims (2)
1, a kind of cutter that is used for vertical lathe and engine lathe, be particularly related to a kind of interior synchronous floating boring tool of external diameter, comprise the cutter hub 2 that is connected with lathe cutter platform, the cutter trousers of installing in cutter hub 2 lower ends 7, the knife bar of installing in the cutter trousers 7 lower end taper holes 9, the internal diameter cutter of in the cutter groove of the lower end of knife bar 9, installing 10, lower end at knife bar 9 is connected with cutter gland 11 with soket head cap screw, it is characterized in that, mill out a locating slot in the middle of the said cutter hub 2, a floating knife beam 3 is installed in the middle of locating slot, and the upper end of said cutter trousers 7 is a plane, forms a floating knife beam location square hole between the last plane of the locating slot of cutter hub 2 and cutter trousers 7; Connect left tool arm 4 and right tool arm 1 at the left and right two ends of floating knife beam 3, in the cutter groove of the lower end of left and right tool arm 4 and 1, be separately installed with external diameter cutter 6.
2, according to claim 1 said in the synchronous floating boring tool of external diameter, it is characterized in that, be connected with soket head cap screw between said floating knife beam 3 and left tool arm 4 and the right tool arm 1.
