The boring cutter shaft structure comprises a driving shaft, a driven shaft and a clutch component, wherein the driven shaft comprises a driven shaft body and a screw; the screw is connected with one end of the driven shaft body; a threaded hole which is matched with the screw is formed in one end of the driving shaft; one end, which is connected with the screw, of the driven shaft body is a driven spline end shaft; the end, with the threaded hole, of the driving haft is a driving spline end shaft; the clutch component controls separation and reunion of the driving shaft and the driven shaft and comprises a spline sleeve sleeved on the driving spline end shaft; and the spline sleeve is matched with the driving spline end shaft and the driven spline end shaft. By using the technical scheme, the technical problems can be effectively solved.
Description
Technical field
The invention belongs to mechanical equipment technical field, relate to a kind of boring cutter axle construction.
Background technology
Boring cutter is indispensable important cutter in precision hole machining, is a kind of of cutting tool for boring, and the most frequently used occasion is exactly endoporus processing, reaming, profiling etc.For example mechanical industry batch production casing (as gearbox) all needs bore hole operation, the size in aperture, the depth has strict requirement, the large I application reamer in hole is controlled, but the depth in hole (as bearing chamber) just must be controlled by adjusting boring cutter axle, and boring cutter axle comprises driving shaft and driven shaft conventionally, and driving shaft generally just can drive driven shaft to rotate after adjustment completes, but it is accurate not that traditional boring cutter axial adjustment mode is adjusted, and operation is difficult for.
Summary of the invention
Technical problem to be solved by this invention is that the precision of existing boring cutter axial adjustment is inadequate, operates difficult problem, and provides a kind of boring cutter axle construction for this problem, and the present invention solves the problems of the technologies described above by the following technical programs:
A kind of boring cutter axle construction, comprise driving shaft and driven shaft, driven shaft comprises driven shaft body and the screw rod being connected with driven shaft body one end, driving shaft one end is provided with the screwed hole matching with described screw rod, it is characterized in that one end that driven shaft body is connected with described screw rod is driven splined end axle, driving shaft is provided with screwed hole one end for driving splined end axle, described boring cutter axle construction also comprises the clutch part of controlling driving shaft and driven shaft clutch, described clutch part comprises the spline housing being enclosed within on driving splined end axle, described spline housing matches with driving splined end axle and driven splined end axle.
Driven shaft drives boring cutter running, after adopting said structure, first rotate driven shaft, screw rod on driven shaft just rotates in the screwed hole of driving shaft, thereby the displacement on producing axially, after driven shaft rotates, by being enclosed within the spline housing driving on splined end axle, to driven splined end direction of principal axis, move, and finally make part spline housing be enclosed within on driven splined end axle, owing to driving splined end axle and driven splined end axle and spline housing to match, now, driven shaft will synchronously rotate along with the rotation of driving shaft, thereby technical staff can start bore hole operation.
Adopt after technique scheme, technical staff can improve easily boring cutter and carry out the size of bore hole and the precision of depth aspect: on the one hand, because the pitch of screw thread is certain, so pass through technique scheme, the angle of rotating screw bolt Yi Ge unit just can make driven shaft that the displacement of Yi Ge unit occurs in the axial direction, the pitch of screw thread can be changed, therefore technical staff can use have more screw rod and the screwed hole of fine pitch completely, the unit displacement that driven shaft occurs in the axial direction like this will be less, it is more accurate that the position adjustment of boring cutter also will become, thereby guarantee the precision of bore hole size and the depth, on the other hand, the angle of bolt rotary can by screw rod spline lattice number in the spline housing of process know, technical staff can arrange angle index in described spline housing end, can indirectly obtain the displacement that driven shaft occurs in the axial direction like this.
At spline housing, entangle and drive after splined end axle and driven splined end axle, driven shaft just can be along with drive shaft turns, but spline housing and drive between splined end axle and/or spline housing and driven splined end axle can not be guaranteed fastening assembling, precision is adjusted in this rotation that not only has a strong impact on driven shaft screw rod, even make spline housing come off from driven shaft splined end axle, to this, clutch part of the present invention also comprises spline housing set bolt, described spline housing is provided with the retaining thread through hole that is communicated with spline housing inside, and described retaining thread through hole and described bolt match.Technical staff can tighten spline housing set bolt on retaining thread through hole, and spline housing can be fixed on driven splined end axle and drive between splined end axle, guarantees that spline housing does not slide when boring cutter operation, affects the precision of boring cutter operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of boring cutter axle construction under clutch two states described in embodiment;
Fig. 2 drives the shaft section structural representation of splined end shaft portion described in embodiment in a kind of boring cutter axle construction.
The specific embodiment
Embodiment
See Fig. 1 to Fig. 2, a kind of boring cutter axle construction, comprise driving shaft 5, driven shaft and the clutch part of controlling driving shaft 5 and driven shaft clutch, driven shaft comprises driven shaft body 1 and the screw rod 6 being connected with driven shaft body 1 one end, one end that driven shaft body 1 is connected with described screw rod 6 is driven splined end axle 12, driving shaft 5 one end are provided with the screwed hole 3 matching with described screw rod 6, driving shaft 5 is provided with screwed hole one end for driving splined end axle 11, described clutch part comprises spline housing (4 or 10) and the spline housing set bolt (2 or 9) being enclosed within on driving splined end axle 11, spline housing (4 or 10) matches with driving splined end axle 11 and driven splined end axle 12, spline housing (4 or 10) is provided with and is communicated with the inner retaining thread through hole of spline housing (4 or 10), described retaining thread through hole and described bolt (2 or 9) match.
For the present embodiment, drive on splined end axle 11 and driven splined end axle 12 and be equipped with six splines 8, also a corresponding angle of spline lattice is 60 °, spline housing (4 or 10) end is provided with angle index, can make technical staff know more accurately the angle that screw rod 6 rotates with respect to spline housing (4 or 10) (also driving splined end axle).
While using described in the present embodiment boring cutter axle construction, first rotating screw bolt 6, the angle that screw rod 6 rotates can be read from the angle index of spline housing end, after rotation, according to formula below, calculates driven shaft 1 displacement in the axial direction:
The angle ÷ 360 that the pitch * screw rod 6 of driven shaft 1 displacement=screw rod 6 in the axial direction rotates with respect to spline housing (4 or 10).
Now the spline housing in clutch part be positioned at from state (be spline housing set bolt and spline housing be respectively 2 and 4 o'clock), mobile spline housing, the state that spline housing is positioned at close (be spline housing set bolt and spline housing be respectively 9 and 10 o'clock), tighten again subsequently spline housing set bolt 9, make in the spline lattice that are stuck in driven splined end axle 1 tightly of spline housing set bolt 9 bottoms, spline housing 10 is fixed on and drives between splined end axle 11 and driven splined end axle 12, then just can carry out the operation of accurate boring cutter bore hole.
