Detailed description of the invention
A kind of dense arrangement hole bur removal tool, it is characterised in that: include regulating screw 1, broach shell 2, drill bit 3, sliding
Pin 4, spring 5；Broach shell 2 upper end center has screwed hole 7, connects lower center endoporus 8, and center is crossed in broach shell 2 cylinder bottom to be had radially
Through waist type gathering sill 6, drill bit 3 is installed in the endoporus 8 of broach shell 2, and its head is spherical, is provided with through hole 9, through hole at drillstock
The centrage of 9 is coplanar with the centrage of drill bit and vertical, sliding pin 4 and the gathering sill 6 on broach shell 2, through hole 9 phase on drill bit 3
Coordinate, sliding pin 4 and gathering sill 6 be the through hole 9 in matched in clearance, with drill bit 3 be interference fit, it is ensured that sliding pin 4 can led
, regulation screw 1 is installed in broach shell 2 threaded upper ends hole 7, and spring 5 is positioned in the screwed hole 7 of broach shell 2 in groove 6 slidably,
Lower end contacts with drill bit 3 upper surface, and its upper surface contacts with the lower surface of regulation screw 1.
Regulation screw 1: for standard screws, having certain adjustable range, compression spring controls the retractility of drill bit.
Broach shell 2: top has screwed hole, is used for connecting regulation screw, places spring simultaneously, and center is crossed in bottom has radial direction to pass through
Logical waist type gathering sill, matches with straight pin, has certain interval, it is ensured that straight pin freely slides up and down.
Drill bit 3: ground by all-purpose bit and form, bit grinding globulate, prevent from scratching piece surface.Through hole it is provided with at drillstock
9, with straight pin interference fit.
Sliding pin 4: use straight pin, have certain matching relationship with drill bit, broach shell, length is not less than broach shell diameter.
Spring 5: be positioned in the screwed hole of broach shell top, there is certain intensity and retractility, it is possible to regulation drill bit is upper and lower
Motion.
Gathering sill 6: being positioned at both sides, the broach shell face of cylinder, symmetrical waist type groove, with straight pin matched in clearance, it is ensured that certain length
Degree.
Screwed hole 7: be positioned at broach shell top, is used for connecting adjustment screw and broach shell.
Endoporus 8: be positioned at broach shell bottom, connect with screwed hole, is used for laying drill bit.
Through hole 9: be positioned at drill bit shank end, with sliding pin interference fit.
Operation principle:
The first step: add man-hour, fits together this deburring tool, is clamped on drilling machine according to accompanying drawing 1；
Second step: be located at by drilling machine locating piece applicable the most locked, when drill bit springs into hole, spring into the limit firm
Arrive well at orifice chamfer burr；
3rd step: workpiece to be added is placed on workbench, promotes part to allow a round at the uniform velocity pass through combined drill；
4th step: when deburring drill bit springs into hole, bit removes aperture burr, part reach, drill bit compression bullet
Spring removal aperture, during to next aperture, drill bit has sprung into deburring work once again.
Through production practices, this instrument effectively realizes the semi-automatic deburring process in piece surface dense arrangement hole, significantly
Improve production efficiency, greatly reduce the manually-operated time, eliminate because the possibility of part hindered by the factor brills such as fatigue simultaneously
Property, orifice chamfer is uniform, it is ensured that crudy.
