Description
Technical field
The present invention relates to technical field of bearing processing, and in particular to bearing ring slanting oil hole machining device.
Background technique
For the service life for extending bearing, logical oil lubrication inclined oil hole of air is equipped with usually on bearing ring.In existing bearing holder (housing, cover)
Circle processing inclined oil hole of air during, be to be placed on bearing ring on one dedicated brill tire for being drilled with inclined oil hole of air, operator with
By means of angle square and experience locating latch oil-hole location, and then complete the processing operation of inclined oil hole of air.Since operator only borrows experience to make
Corresponding positioning out, inevitably causes inclined oil hole of air position deviation, and difficulty of processing is larger, is difficult to control.
Summary of the invention
The purpose of the present invention is to provide a kind of accurate positioning and the small bearing ring inclined oil hole of air of difficulty of processing processes dress
It sets.
In order to achieve the above objectives, the present invention adopts the following technical scheme:
The table top of bearing ring slanting oil hole machining device, including rack, rack is equipped with bearing ring fixed mechanism, rack
Table top be magnechuck, bearing ring fixed mechanism includes the stepped hole being provided on rack table；Above the table top of rack
Rotating mechanism and borehole drill construction are equipped with lower section, and rotating mechanism includes rotation connection the first turntable on the rack and second turn
Disk, the first turntable are greater than the second turntable at a distance from rack table at a distance from rack table, the first turntable and the second turntable
Rotation center with the center overlapping of axles of stepped hole, offers first through hole on the first turntable, offers second on the second turntable
Through-hole, the angle at first through hole center and the second through hole center line and bearing ring central axis above the table top of rack
For the first angle, first through hole center and the second through hole center line and bearing ring central axis below the table top of rack
Angle be the second angle, the first angle is equal with the second angle；Borehole drill construction includes rotating bar and is fixed at rotating bar
Electric drill on one end, rotating bar are fixed in first through hole and the second through-hole, and electric drill is located on the outside of bearing ring, two electricity
Brill is staggered in the circumferential direction of bearing ring, and the sum of drilling depth of two electric drills is equal to bearing ring inclined oil hole of air depth；Rack
On be additionally provided with rotation park mechanism, rotation park mechanism includes that several are used to control microswitch and the triggering of electric drill power on/off
Block, several microswitches are fixed on the rack and circumferentially distributed along the central axis of bearing ring, and triggering block and electric drill are solid
Fixed connection.
The working principle of this programme is:
The bearing ring fixed mechanism being arranged on rack table is used for fixing bearing lasso, and bearing ring fixed mechanism includes
The stepped hole being provided on rack table, for as the supporting structure in bearing ring axial direction and as bearing ring radial direction
On fixed structure, rack table is magnechuck, when magnechuck be powered when, bearing ring can be fixed in stepped hole
Prevent bearing ring from rotating.
Borehole drill construction is used for the inclined oil hole of air on auger spindle bearing ring, supporting structure of the rotating bar as electric drill, rotating mechanism
In driving rotating bar rotation, so that electric drill be driven to rotate, multiple inclined oil hole of air can be bored on bearing ring.
In rotating mechanism, the first turntable and the second turntable are set, are in order to which rotating bar to be also secured on the first turntable
First through hole and the second turntable on the second through-hole in, the first turntable and the second turntable rotation, drive rotating bar rotate together,

To distribution, triggering block is fixedly connected with electric drill, and when electric drill is rotated with triggering block, triggering block touches microswitch, fine motion
Switch control electric drill starts to drill.
Following technical effect can be reached using this programme:
1, it is capable of fixing the angle of electric drill by first through hole and the second through-hole, avoids electric drill that radially and tangentially inclined occurs
It moves, ensure that bore position and the direction of inclined oil hole of air, difficulty of processing is small, easily controllable；
2, the different bore angles of electric drill be can determine that by the different radiuses of rotation of setting first through hole and the second through-hole；
3, electric drill can bore multiple inclined oil hole of air, after retightening bearing ring around the central axis rotation of bearing ring
It drills again；
4, it drills from two opposite directions of inclined oil hole of air, reduces the drilling depth of the same electric drill, reduce
The case where electric drill shifts when drilling, and it is conducive to chip removal；
5, it is able to achieve the automatic park and work of electric drill by microswitch and triggering block, and only needs setting microswitch
Position just can determine that bore position.
Further, the drilling depth of the electric drill above and below rack table is bearing ring inclined oil hole of air depth
1/2.It revolves and turns around when shaft, the processing of inclined oil hole of air can be completed, and the drilling depth of two electric drills is consistent, so that two electric drills
Job security generally remain unanimously, reduce the case where one of electric drill breaks down probability greater than another electric drill.
Further, microswitch is at least four, the hole count being spaced between the electric drill above and below rack table
At least one.When can bore four inclined oil hole of air, and can guarantee two electric drill drilling, oilhole has enough cooling times, bores
Hole effect is more preferable.
Further, the sidewall slope of first through hole and the second through-hole is consistent with the gradient of rotating bar, and rotating bar with
The side wall of first through hole and the second through-hole is affixed.It ensure that rotating bar and the side wall of first through hole and the second through-hole are close to, reduce
The case where rotating bar shakes in first through hole and the second through-hole.
Further, several rolling elements are equipped between the first turntable and the second turntable and rack.Several rolling elements are protected
It has demonstrate,proved the first turntable and when the second turntable rotates on the rack keeps Plane Rotation, and rotated more steady.
Further, shaft is rotatably connected in rack, the first turntable and the second turntable are fixedly connected in shaft, rack
On be additionally provided with for drive shaft rotation servo motor.Servo motor is rotated for drive shaft, and servo motor being capable of essence
The really time of control shaft rotation and park, shaft rotate while the first turntable and the second turntable being driven to rotate together, ensure that
First turntable and the angular speed of the second turntable rotation are identical, that is, ensure that the stability of rotating bar rotation, to ensure that drilling
Stability.
