Abstract

The utility model discloses a kind of brill, the anti-spot-facing cutter of boring, comprise knife bar and the blade bearing assembly being arranged on described knife bar lower end, it is characterized in that described blade bearing assembly comprises blade bearing, is embedded in the blade of described blade bearing upper surface and passes across the lateral pin of described blade bearing, described probe portion is placed in the axial installing hole of described blade bearing; The lower end diameter of described knife bar with to process clear size of opening suitable, the end of described knife bar has a mounting plane, at least offers arc groove in the side of described mounting plane.During use, knife bar process through hole through institute, then blade bearing assembly is arranged on knife bar lower end, rotating knife bar, makes lateral pin fall into the arc groove inner position of knife bar end, rotation adds leans on this lateral pin to drive and hold blade bearing and carries out spot-facing processing man-hour.With this type of spot-facing of this tool sharpening, not only ensure its shape and positional precision, and use is flexible, convenient, manufactures also uncomplicated.

Description

Brill, the anti-spot-facing cutter of boring
Technical field
The utility model relates to field of machining, particularly relates to cutter field, specifically a kind of brill, the anti-spot-facing cutter of boring.
Background technology
Large-scale lathe base, box parts, designer, when designing shirt rim fixing hole, in order to allow securing member not interfere with other parts, ensures that the contact surface of securing member is smooth, usually at this through hole spot-facing again.But not only need specific customization lengthening drill bit at this kind of part of processing, and after drill bit lengthening, not only affect the positional precision in hole, and working (machining) efficiency is also extremely low.So find one cleverly mode process this pores, thus ensure the quality of part and to enhance productivity be very necessary.
Summary of the invention
The above-mentioned technical problem being prior art and existing to be solved in the utility model, aims to provide a kind of machining accuracy brill high, flexible and convenient to use, the anti-spot-facing cutter of boring.
For solving the problem, the utility model is by the following technical solutions: bore, the anti-spot-facing cutter of boring, comprise knife bar and the blade bearing assembly being arranged on described knife bar lower end, it is characterized in that described blade bearing assembly comprises blade bearing, is embedded in the blade of described blade bearing upper surface and passes across the lateral pin of described blade bearing, described probe portion is placed in the axial installing hole of described blade bearing; The lower end diameter of described knife bar with to process clear size of opening suitable, the end of described knife bar has a mounting plane, at least offers arc groove in the side of described mounting plane.
Brill of the present utility model, the anti-spot-facing cutter of boring, during use by knife bar through process through hole, then blade bearing assembly is arranged on knife bar lower end, rotating knife bar, make lateral pin fall into the arc groove inner position of knife bar end, rotate to add to drive by this lateral pin and hold blade bearing man-hour and carry out spot-facing processing.With this type of spot-facing of this tool sharpening, not only ensure its shape and positional precision, and use is flexible, convenient, manufactures also uncomplicated.
As improvement of the present utility model, the both sides of described mounting plane offer arc groove respectively, can select flexibly for the different installation directions of blade.
As further improvement of the utility model, described blade is one group, is evenly distributed on the upper surface of described blade bearing.Described blade is advisable with 3-4.

Detailed description of the invention
With reference to Fig. 1, brill of the present utility model, the anti-spot-facing cutter of boring, comprise knife bar 1 and the blade bearing assembly 12 being arranged on described knife bar 1 lower end.
With reference to Fig. 2, described blade bearing assembly 12 comprises blade bearing 3, is embedded in the blade 2 of described blade bearing 3 upper surface and passes across the lateral pin 4 of described blade bearing 3, and described lateral pin 4 part is placed in the axial installing hole 11 of described blade bearing 3; Described blade 2 is 4, is evenly distributed on the upper surface of described blade bearing 3.
With reference to Fig. 3 and Fig. 4, the lower end diameter of described knife bar 1 with to process clear size of opening suitable, the end of described knife bar 1 has a mounting plane 8, offers arc groove 9 respectively, 10 in the both sides of described mounting plane 8.
With reference to Fig. 5, the course of work of the present utility model is as follows:
1, be installed on machine tool chief axis 5 by knife bar 1, the end of knife bar 1 is from top to bottom through the processing through hole on the shirt rim 7 of part to be processed 6.
2, blade bearing assembly 12 is arranged on knife bar 1 lower end, the axial installing hole 11 of blade bearing is inserted in knife bar 1, and makes the mounting plane of knife bar 1 relative with lateral pin 4.
3, rotating knife bar 3, makes lateral pin 4 fall into arc groove 9 or 10 (depending on blade direction of rotation) inner position.
4, open lathe switch, machine tool chief axis 5 drives knife bar 1 to rotate, and lateral pin 4 drives and spot-facing processing is carried out in the bottom surface, shirt rim 7 holding blade bearing 3 pairs of parts to be processed 6.
It is understood that above-described embodiment is just to explanation of the present utility model, instead of to restriction of the present utility model, any innovation and creation do not exceeded in the utility model spirit, all fall within protection domain of the present utility model.
