Description
Technical field
The utility model is related to a kind of Boring machine boring bar technology, the against shock boring bar machine of particularly a kind of adjustable rotating speed
Structure.
Background technology
Since China reforms and opens up to the outside world, national economy obtains rapid growth, has turned into current with " scientific and technical innovation, autonomous innovation "
The main flow of domestic industry development, " strong, the middle Guoqiang of science and technology " turns into the process for promoting China's scientific and technological revolution, and China's industry is just progressively
Develop to intensive style, energy-saving and emission-reduction, low-carbon, the intelligentized direction of high-tech.Often to be run into machinery production on part
Bore hole, in the part of bore hole the need for difference is run into during bore hole, generally require use to should part material rotating speed
Boring machine, could the more rapidly bore hole on the part, if rotating speed is mismatched, not only processing trouble, and being damaged to boring cutter
Wound than larger, and processing is big and during long hole, boring bar is very long, and rigidity is very poor, easily shakes, reduces crudy, has
When even processing can be caused not carry out, cost is not only added in process of production, and cumbersome.In China is of the same trade
Scientific research personnel constantly go to explore, study, although make some progress, but remain in actual applications not yet
The technical barrier overcome.
The content of the invention
The purpose of this utility model is to overcome the above, and not enough there is provided a kind of against shock boring bar mechanism of adjustable rotating speed.
It is designed on the basis of original boring bar, provided with a ball-screw coaxial with boring bar inside boring bar, and promotes boring
Bar is moved, a double linked wheel connection boring bar synchromesh gear and a damping gear, when processing the part of unlike material, Ke Yitong
The gear proportioning for changing damping gear and double linked wheel is crossed, changes boring bar rotating speed to adapt to the bore hole demand of part, not only processes fast
Speed, and the abrasion to boring cutter is reduced, time and labour saving is also provided with a moveable fixed cover on the outside of boring bar, can
Change the position of fixed cover with the length depending on bore hole, fixed effect is than immovable fixed cover more preferably.
The utility model solves the technical scheme that its technical problem used：Contain casing, fixed cover, shaft coupling, boring
Bar, ball-screw, double linked wheel, boring bar synchromesh gear, damping gear, are provided with rectangular casing, in case on the outside of boring bar
The front of body, in the outside of boring bar, a rolling with boring bar coaxially is provided with the inside of boring bar provided with a moveable fixed cover
Ballscrew, and be connected by shaft coupling with boring bar, in the lower end of boring bar provided with a boring bar synchromesh gear, set on the outside of casing
There is a damping gear, provided with a double linked wheel connection damping gear and boring bar synchromesh gear, constitute a kind of adjustable rotating speed
Against shock boring bar mechanism.
Technical principle of the present utility model is：Using theory of mechanics technology, it is connected provided with a ball-screw with boring bar,
When boring bar works, by the way that to damping gear applying power, damping gear drives double linked wheel work, and directly drives boring by double linked wheel
Bar synchromesh gear rotates, when boring bar works, and boring bar drives the ball-screw connected by shaft coupling to rotate, when boring bar and ball
Differential is produced during leading screw rotating Vortex, ball-screw is produced continuous automatic rotation, when needing the part to unlike material
When carrying out bore hole, regulation rotating speed can be matched by adjusting the gear of damping gear and double linked wheel, and one is provided with boring bar outer end
Individual moveable fixed cover, when needing to process long hole, can be such that fixed cover is moved with the feeding of boring bar, prevent
The vibrations of boring bar.
The beneficial effects of the utility model are：A kind of against shock boring bar mechanism of adjustable rotating speed, provided with a double linked wheel
Boring bar synchromesh gear and a damping gear are connected, can be by changing damping gear when the part of unlike material to be processed
The rotating speed for changing boring bar synchromesh gear is reached with the gear proportioning of double linked wheel so that the rotating speed of regulation boring bar, not only the scope of application
Extensively, and it can prevent boring cutter from causing the abrasion to boring cutter when processing the part of unlike material under same rotating speed, bore hole is more accelerated
Victory is convenient, time saving and energy saving, in the outside of boring bar provided with a moveable fixed cover, can the hole of boring bar processing length compared with
When long, change the position of fixed cover with the feeding of boring bar, it is therefore prevented that the vibrations of boring bar cause bore hole to fail, reduce production
Cost and loss, add the qualification rate of product.
Brief description of the drawings
Here is that the utility model is further illustrated with reference to accompanying drawing and example：
Fig. 1 is：A kind of against shock boring bar mechanism structural representation of adjustable rotating speed
