Abstract
The utility model discloses an inner hole machining tool with an adjustable machining radius, which comprises a tool bar. The technical scheme includes that a groove is arranged at one end of the tool bar, a blade is mounted in the groove, an adjusting device and a pressing device are arranged on the tool bar, the adjusting device adjusts the cutting radius of the blade, and the blade is fixedly pressed by the pressing device. The pressing device consists of a press plate and a bolt, the press plate is pressed on the blade, and the bolt penetrates through the press plate and presses and fixes the press plate onto the tool bar. The adjusting device comprises a threaded hole arranged on one side of the groove, the threaded hole is opposite to the tail end of the blade and is fittingly provided with a screw, and the blade is ejected by the screw so as to radially stretch and contract. Accordingly, the position of the blade is adjusted by means of adjusting the screw, and machining precision of the tool is improved. The press plate has functions of fastening the blade and breaking chips, so that the tool is firmer and safer. The inner hole machining tool is simple and can be adjusted conveniently.
Description
[technical field]
The utility model relates to a kind of machine cut cutter, the new type of bore process tool that particularly a kind of radius is adjustable.
[background technology]
All can use interior aperture knife tool when the machining endoporus, traditional interior aperture knife tool is a welded type, is about to blade and is welded on the knife bar.Because when welding, high temperature descended the hardness of blade, influenced the service life of cutter on largely, and knife bar to be changed thereupon also when breaks down, waste material.
China utility model patent CN98245167.9 discloses a kind of adjustable cutter, and this cutter is to be provided with the hole that blade can be put into wherein at the knife bar front end, and vertical with this hole and a communicate screwed hole is set, and is provided with bolt in the screwed hole.Fix and adjust the position of blade during use by the adjusting bolt.Changing knife rod more when this device has been realized breaks down, and blade position can be adjusted.But the adjustment inconvenience of knife bar position, machining accuracy is not high, and fixing of bolt is also insecure, is very easy to loosening in process.
[utility model content]
The purpose of this utility model provides a kind of adjustable blade position, convenient adjustment, machining accuracy is high and well-set interior aperture knife tool, and the knife bar of cutter can reuse, and blade can fully wear and tear and improve the life-span of cutter.
In order to address the above problem, the utility model by the following technical solutions:
A kind of adjustable interior novel aperture knife tool of radius of processing, comprise knife bar, it is characterized in that: be provided with groove at described knife bar one end, in the described groove blade is installed, described knife bar is provided with the adjusting device of adjusting described blade cut radius and the hold down gag that described blade pressing is fixed.
Aforesaid a kind of adjustable new type of bore process tool, it is characterized in that: described hold down gag comprises the pressing plate that is pressed on the described blade, passes pressing plate and it is pressed abd fixed on bolt on the knife bar; The pressing plate lower surface is provided with cylindrical boss and is inserted in the locating hole on the knife bar.
Aforesaid a kind of adjustable new type of bore process tool, it is characterized in that: described adjusting device comprises and is arranged on groove one side and the relative screwed hole of described blade tail end that described screwed hole coupling is equipped with the screw that the described blade of roof pressure makes its radial expansion.
The beneficial effects of the utility model have: after adopting said apparatus, when the adjustment knife bar still can not satisfy processing dimension or precision when carrying out machining, can adjust the position of blade by rotary screw, improve the precision of processing.Utilize pressing plate to compress and make whole device more fastening, and knife plate can also play the effect of the metal fillings on the cutter blades.

[specific embodiment]
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of adjustable new type of bore process tool of radius of processing, comprise knife bar 1, be provided with groove 3 at described knife bar 1 one ends, in the described groove 3 blade 2 is installed, the tool cutting edge angle of blade is 90 °, and described knife bar 1 is provided with the adjusting device 5 of adjusting described blade 2 radiuss of clean-up and the hold down gag 4 that described blade 2 is fixed.The other end of knife bar is installed on jig or other devices.
Described hold down gag 4 comprises the pressing plate 401 that is pressed on the blade 2, passes pressing plate 401 and it is pressed abd fixed on bolt 402 on the knife bar 1.In order to prevent rotation, be provided with cylindrical boss 6 in pressing plate 401 lower surfaces and be inserted in the locating hole 7 on the knife bar 1 at working angles center platen 401.Pressing plate 401 has played the effect that is fixed the metal fillings on blade 2 and the cutter blades 2 simultaneously.
Described adjusting device 5 comprises and is arranged on groove 3 one sides and the relative screwed hole 501 of described blade 2 tail ends that described screwed hole 501 couplings are equipped with the screw 502 that the described blade 2 of roof pressure makes its radial expansion.Blade 2 can be adjusted to needed position by rotary screw 502, adjust the processing radius, improve machining accuracy.
As shown in Figure 5, the tool cutting edge angle of described blade 2 is a 45, the tool cutting edge angle that can select blade 2 according to the shape or the position of part to be processed.
During use, the right-hand member of knife bar 1 is installed on jig or other devices.The position of adjusting knife bar 1 makes the blade 2 and the part of required processing arrive fixedly knife bar 1 of suitable distance.Rotary screw 502 is adjusted the position of blade 2 to required processing radius once more then, guarantees to add the machining accuracy in man-hour simultaneously.After adjusting to the right place, tight a bolt 402, make pressing plate compress blade.
