Description
Technical field
The present invention relates to the adjusting device of the process tool of engineering goods part, especially micrometer adjustement boring tool.
Background technology
Now the conventional method in the high hole of required precision is to finish with boring cutter at boring machine on the processing equipment part.Personage of the same trade knows that the size of bore diameter size is by the distance decision of cutter head point to the boring cutter pivot.Kong Zhongyong screw or bolt that general cutter head is contained in boring bar compress, and the cutter head point can only lean on the position of each push type broach to realize to the distance of boring cutter pivot, toolsetting trouble inaccuracy.Particularly during the accurate hole of boring, crudy be a greater impact and efficient low.
Summary of the invention
The purpose of this invention is to provide a kind of micrometer adjustement boring tool, can adjust to accurate position to the boring cutter point rapidly and accurately.
The technical solution adopted for the present invention to solve the technical problems is: utilize gradient and screw mechanism to finish accurate toolsetting task.
Micrometer adjustement boring tool is made up of cutter hub, locking nut, spring, pivoted housing, sliding sleeve, pin, flexible knife bar, screw, cutter head and bolt.Cutter head is contained in the Kong Zhongyong screw in compression of flexible knife bar front end, flexible knife bar is contained in the inclined hole of cutter hub and compresses with bolt, pin is contained in respectively on the flexible knife bar and the hole cutter hub axis normal and the sliding sleeve in the corresponding hole by the groove on the cutter hub, sliding sleeve is contained on the cylinder of the big end of cutter hub, the internal thread of pivoted housing cooperates with the external screw thread of sliding sleeve back, the big endoporus of pivoted housing is contained on the cylindrical of sliding sleeve, one end of spring is contained on the flexible knife bar small column, the other end is contained in the corresponding aperture on the knife bar, two locking nuts are contained on the corresponding double-screw bolt of cutter hub, on sliding sleeve and the cylindrical that pivoted housing cooperates a groove parallel with its axis is arranged, the groove that a plurality of five equilibriums are arranged on the pivoted housing conical surface in front, the small end of cutter hub are the taper shanks that is connected with lathe.
When needing to adjust cutter head in the process of bore hole, unclamp the bolt that compresses flexible knife bar.Adjust the stroke of cutter head as required, press scale rotation corresponding on the pivoted housing, can adjust to cutter head exactly needs the position.Compress flexible knife bar with bolt, finish the toolsetting process.
The advantage of this micrometer adjustement boring tool is: the toolsetting amount is accurate, and reliable, the toolsetting process is convenient and swift.

The specific embodiment
Boring cutter is connected with machine tool chief axis with the taper shank of cutter hub (1) back, the Kong Zhongyong screw (8) that cutter head (9) is contained in flexible knife bar (7) front end compresses, and equally with common boring cutter can progressively finish the heavy boring and half right boring in hole by the position of cutter head (9) in the hole of flexible knife bar (7).
The toolsetting structure is seen accompanying drawing 1, and flexible knife bar (7) is contained in the inclined hole of cutter hub (1) and compresses with bolt (10).Flexible knife bar (7) is a matched in clearance with cooperating of cutter hub (1) inclined hole, optional H7/g6, and the planar top of bolt (10) front end is seen accompanying drawing 2 on being contracted in the parallel plane of the axis with it of knife bar (7) in pressure stretch.Compress with bolt (10) during bore hole, unclamp during toolsetting.Pin (6) is contained in respectively on the flexible knife bar (7) and hole cutter hub (1) axis normal and the sliding sleeve (5) in the corresponding hole by the groove on the cutter hub (1).Pin (6) is a matched in clearance with cooperating of hole with cutter hub (1) axis normal on the flexible knife bar (7), optional F8/h7, upward cooperating for excessively cooperating optional K7/h6, sliding sleeve (5) to be contained on the big cylinder of holding of cutter hub (1) of corresponding hole is the optional H7/g6 of matched in clearance to pin (6) with sliding sleeve (5).Pivoted housing (4) is contained on the double-screw bolt of sliding sleeve (5) rear end with its internal thread, and pitch is 2 millimeters, and fit clearance is as far as possible little.The big endoporus of pivoted housing (4) is contained in and is the optional H8/f7 of matched in clearance on the cylindrical of sliding sleeve (5).The little endoporus of pivoted housing (4) is contained in cutter hub (1) and holds greatly near cutter hub (1) that the gap is 0.5 millimeter on the small column of cylinder.One end of spring (3) is contained on the small column of flexible knife bar (7), and the other end is contained in the corresponding aperture on the knife bar (7), and the effect of spring (3) is the gap of eliminating hole on pin (6) and the flexible knife bar (7) and pivoted housing (4) and sliding sleeve (5) threaded engagement.Two locking nuts (2) are contained on the corresponding double-screw bolt of cutter hub (1) holds the corresponding end face of cylinder to limit moving axially of pivoted housing (4) greatly with cutter hub (1), by the position of adjusting two locking nuts (2) pivoted housing (4) can be rotated and the axial gap minimum.Rotate pivoted housing (4) sliding sleeve (5) is moved axially along cutter hub (1), force flexible knife bar (7) to move along the axis of the inclined hole of cutter hub (1).The gradient of the axis of cutter hub (1) and the axis of inclined hole is 5: 1, and sliding sleeve (5) moves 5 millimeters along the axis of cutter hub (1) like this, is contained in move radially 1 millimeter of the position of cutter head (9) in the hole of flexible knife bar (7) front end at cutter hub (1).On the groove that 200 five equilibriums are arranged on pivoted housing (4) conical surface in front, sliding sleeve (5) and cylindrical that pivoted housing (4) cooperates a groove parallel with its axis is arranged,, see accompanying drawing 3 as datum line.Pivoted housing (4) rotates a circle like this, and sliding sleeve (5) moves 2 millimeters, and the position that is contained in cutter head (9) in the hole of flexible knife bar (7) front end is 2 millimeters ÷ 5=0.4 millimeters moving radially of cutter hub (1).Pivoted housing (4) turns to an adjacent groove from a groove, and the position that is contained in cutter head (9) in the hole of flexible knife bar (7) front end is 0.4 millimeter ÷ 200=0.002 millimeter moving radially of cutter hub (1).Groove is on the circle of φ 72, thus between the groove apart from ≈ 72 * 3.14 ÷ 200=1.1304 millimeters, on so wide distance, might be controlled at 0.001 millimeter (groove is in centre of distance) during toolsetting.Rotating pivoted housing (4) under the indication of scale can accurately adjust to cutter head and need the position.The small end of cutter hub (1) is the taper shank that is connected with lathe.
