Description
Technical field
The utility model belongs to the special processing technology that advanced manufacture is processed with automation-Precision Machining and special material and led
Domain, and in particular to precision lapping machine grinder head.
Background technology
The industry work in-process such as machinery, mould, frequently refer to be ground the endoporus of metal works, make its inner hole wall
Meet roughness, linearity equally accurate requirement.During common grinding lathe attrition process circular inner hole workpiece, abradant surface forms a circle
Line thread path is enclosed, therefore has the workpiece of strict demand to roughness, common grinding lathe does not reach endoporus grinding precision will
Ask.The limitation of common grinding lathe is that circular inner hole workpiece can only be processed, and for various irregularly-shaped inner holes outside circular inner hole
Workpiece can not attrition process.Most of lapping machine of in the market is horizontal machine tool, and operating personnel can be caused by working long hours
Waist is extremely tired.
Utility model content
The utility model adds in order to solve the above technical problems, providing a kind of two kinds of achievable spin finishing and vibro-grinding
Work mode, it is simple in construction, it is easy to the endoporus precise finiss head made.
To realize the utility model purpose, there is provided following technical scheme：A kind of endoporus precise finiss head, including machine
Head, the frame in head, the vertical processing axle being installed in frame, the rotating mechanism for driving processing axle rotation, rotating mechanism bag
Include with processing the No.1 servomotor that axle top is connected by shaft coupling, the grinding stone being connected with vertical processing axle bottom vertically, its
It is characterised by being additionally provided with micro- micro-vibration mechanism shaken above and below drive processing axle, the micro-vibration mechanism includes and vertical processing axle
Vertically disposed eccentric shaft, with No. two servomotors that eccentric shaft left end is connected by shaft coupling, chimeric with processing axle be servo-actuated
Part, two supporting rollers on follower, eccentric shaft right-hand member and two supporting rollers, which coordinate, to be driven.
As a further improvement, being separately provided with processing pedestal on processing axle vertically, process pedestal and frame is affixed, process axle
Vertical rack is installed, vertical rack side is provided with outer motor rack, and outer motor rack is fixed on head, on outer motor rack on frame
No. three servomotors are installed, No. three servomotor spindles are provided with gear, and gear engages with vertical rack, and vertical rack is with adding
Work axle is parallel, drives processing pedestal upper and lower displacement, so as to drive processing axle to move up and down.Moment of torsion during No. three servomotor work
Pass to gear so that pinion rotation, vertical rack move under the tooth engagement of gear, because No. three servomotors are solid
Fixed, and frame and processing pedestal are movable in head, so the rotating of No. three servomotors of regulation can realize rack
Opposite both direction motion, therefore processing axle can be made to automatically move back and forth up and down, when the length of rack is 300mm, once may be used
The depth capacity for processing endoporus is 300mm.
Preferably, follower is formed by left and right two is affixed, two supporting rollers between the upper and lower every being installed on left part end face,
And can freely roll, eccentric shaft right-hand member is between two supporting rollers and tangent with both, and right part is rolled by bearing block, two cylinders
Sub- bearing, the threaded cap and cover plate of upper and lower side are formed, and are processed on axle and are correspondingly arranged on expanding reach, bellend upper and lower side is respectively set with
One cylinder roller bearing, processes axle and cylinder roller bearing is integrally embedded in bearing block.
Preferably, follower in frame with having embedded a root long cube guide block.Prevent follower because eccentric shaft rotate when
By with the fine motion for having fore-and-aft direction.
The utility model beneficial effect：The utility model head is when to circular inner hole attrition process, No.1 servomotor
Open processing axle to rotate forward, work piece rotates with processing axle in opposite direction, and the grinding stone installed in processing shaft end tangentially grinds quilt
Workpiece inner hole wall, and adjust No. three servomotors and realize automatic reciprocating grinding.But such a mode inner hole wall meeting when grinding
A circle circle line thread path is formed, grinding downwards and two opposite curved-line thread paths that grinding is formed upwards intersect to form grid
Shape, compared to unidirectional grinding, although the inner hole wall roughness back and forth ground is small, it is clear that can also improve.
Finer for grinding, we are provided with the device for completing micro-vibration action up and down in above-mentioned grinding step,
So that screw thread straight line becomes sinusoids, so as to improve grinding precision grade, grinding efficiency is also improved.
Can also solve various irregularly-shaped inner hole attrition process outside circular inner hole by above-mentioned this micro-vibration mode.Adding
During work irregularly-shaped inner hole, matched grinding stone is changed, opens and adjust the servomotor for producing micro-vibration so that grinding stone can be right
Irregularly-shaped inner hole wall vibrations are ground, and are then turned on and are adjusted the rotating of stroke servomotor, make automatic reciprocating function.
Above-mentioned described motor uses servomotor, so positive and negative rotating speed can be adjusted, meets to endoporus not
With the attrition process of roughness requirements.The application of micro-vibration function, it can not only improve grinding precision, improve grinding efficiency, and
And can solve the irregularly-shaped inner hole grinding function that other circular inner hole lapping machines can not be completed, this lapping machine exploitation with
Using being above a big innovation.
