Description
Technical field
The utility model relates to Machining Technology field, particularly a kind of bore hole chamfering face work boring head of gapless driving.
Background technology
In mechanical part processing, often running into should the situation of the bore hole end face of machining hole again.Traditional process first uses milling cutter milling flat, then tool changing bore hole, chamfering.When processing parts in enormous quantities, technical process is more loaded down with trivial details, and is difficult to the perpendicularity ensureing hole end surface and hole.If adopt special plane processing parts, be difficult to again to realize bore hole, chamfering, face work once complete.At present, market has several bore hole face work boring head, can complete under the cooperation of building-block machine should the technique of bore hole face work again, but due to drive gap, the precision of face work is not high, sometimes can produce the phenomenon of lifts.It is more obvious that long-time use post gap increases problem.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of bore hole chamfering face work boring head of gapless driving.Tight mesh, makes process steady, improves machining accuracy.
For achieving the above object, the utility model realizes by the following technical solutions:
The bore hole chamfering face work boring head of gapless driving, comprises boring head body, central shaft, gear, vertical tooth rack, tool-bar for accurately boring, chamfering tool rest, face work knife rest; Boring head body front end is provided with tool-bar for accurately boring, tool-bar for accurately boring is provided with right boring knife rest, the side of tool-bar for accurately boring is provided with chamfering tool rest, opposite side is provided with face work knife rest, boring head body inner bolt fixed vertical tooth bar, boring head body central mounting center axle, central shaft is provided with teeth, gear engages with vertical tooth rack and central shaft, is provided with spring supporting on the bearing holder (housing, cover) of gear shaft at gear and central shaft 45 degree of angular position.
Described gear shaft is moveable at gear and central shaft 45 degree of angle directions.
Described bearing holder (housing, cover) endoporus is circular outer is square.
Compared with prior art, the beneficial effects of the utility model are:
The axle of the utility model gear is transportable in 45 degree of directions, by spring strength by gear tightly compacting on vertical tooth rack and central shaft tooth bar, thus achieve tight mesh.After using even if long-time, although gear and tooth bar have worn and torn, due to the effect of spring and removable gear shaft, still can ensure tight mesh reliably, thus ensure that machining accuracy.The utility model can make the model of different size according to the size of part to be processed, fit in special plane with building-block machine.Production efficiency improves greatly.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1 and Figure 2, the bore hole chamfering face work boring head of gapless driving, comprises boring head body 1, central shaft 2, gear 3, vertical tooth rack 4, tool-bar for accurately boring 5, chamfering tool rest 8, face work knife rest 7; Boring head body 1 front end is provided with tool-bar for accurately boring 5, tool-bar for accurately boring 5 is provided with right boring knife rest 6, the side of tool-bar for accurately boring 5 is provided with chamfering tool rest 8, opposite side is provided with face work knife rest 7, boring head body 1 inner bolt fixed vertical tooth bar 4, boring head body 1 centre bore mounting center axle 2, central shaft 2 is provided with teeth, gear 3 engages with vertical tooth rack 4 and central shaft 2, is provided with spring 10 is supported on the bearing holder (housing, cover) of gear shaft at gear and central shaft 45 degree of angular position.
As shown in Figure 3, in gear and central shaft engagement, spring supporting is on the bearing holder (housing, cover) of gear shaft, and bearing holder (housing, cover) endoporus is circular outer is square.Gear shaft is moveable under spring supporting.
As shown in Figure 4, the using method of boring head, installs cutter by each knife rest, and part to be processed, when bore hole, does not have relative motion between central shaft and boring head body, only completes bore hole and chamfering by the rotation of boring head body and the feeding of boring head body.When face work, boring head body only rotates not feeding, and now central shaft moves forward and backward, and is moved, complete face work by rack pinion band motor-driven vehicle end surface knife rest.When face work knife rest moves, due to the effect of spring and removable gear shaft, remain that tooth bar is close to by gear, gapless, knife rest moves steadily, effectively improves machining accuracy,
Be only general principle of the present utility model above, not impose any restrictions the utility model, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
