Description
Technical field
The invention belongs to bearing apparatus technical field more particularly to a kind of bearing processing apparatus.
Background technique
Hydrodynamic bearing is that the liquid film formed by liquid lubricant dynamic pressure separates two friction surfaces and load bearing
Sliding bearing, and generate and two rubbing surfaces is most importantly needed to have enough speed of related movement in the condition of hydrodynamic pressure,
Therefore often all design has concave-convex channel to the inner surface of hydrodynamic bearing.In order to which the inner surface of bearing is processed concave-convex ditch
Road, traditional method are as follows: upper low punch will be used to clamp bearing first when processing, shaping dies is inserted into bearing
Zhou Zhong, then insert a bearing into diameter and be less than in second mold of bearing inner circumferential diameter, while pushing upper punching using pressure head
Head, the convex stripe on shaping dies are just transferred, and then bearing and second mold relative motion, finally take out bearing.
It can be seen that the mold that the needs of conventional method are sized for according to the size selection of required bearing, is marked
When also need to consider the wall thickness of processed bearing, if the wall thickness of bearing is relatively thin, be not enough to that its is supported to carry out elastic deformation；If
The wall thickness of bearing is thicker, then the concave-convex channel transferred out is shallower, simultaneously because mold size is fixed, it is desirable to process width
Groove just needs replacing different molds, also increases to the requirement of mold.
Summary of the invention
The purpose of the present invention is to provide a kind of bearing processing apparatus, realize that on bearing, simultaneous processing goes out multiple to have one
The groove of depth and width is determined, to improve processing efficiency.
In order to achieve the above object, base case of the invention are as follows: bearing processing apparatus, including rack, for processing axis
The processing unit held and the fixed cell for fixing bearing, rack are equipped with limit film, and processing unit includes driving portion, adds
The Ministry of worker and tight lock part, driving portion include servo motor, main synchronous pulley and from synchronous pulley, stepper motor and main synchronous pulley it
Between be fixed with first rotating shaft, main synchronous pulley is mutually perpendicular to the center line from synchronous pulley, axial from the tooth of synchronous pulley
Equipped with locking hole；Processing department includes the fixed block being arranged on the rack, and is equipped with gear and rack gear in fixed block, gear with from synchronous
Belt wheel is fixed, and rack gear is two, rack and pinion engagement, is equipped with cutter on rack gear；Tight lock part includes cam and vertical hinged
Pin shaft on bracket, cam and main synchronous belt are coaxially disposed, and one end of pin shaft offsets with the cam contour, the other end and lock
Tieholen is opposite；Fixed cell, the driving portion for clamping and rotating including clamping jaw and for controlling clamping jaw, rotating part and servo motor are equal
It is fixed on the rack.
It the principle of the present invention and has the technical effect that
1, servo motor can be realized positive and negative rotation, when servo motor rotates forward, due to servo motor and main synchronous pulley
It is fixed with cam coaxial, main synchronous pulley is engaged with from synchronous pulley by synchronous belt, it is fixed again with gear from synchronous pulley, because
This servo motor drives main synchronous pulley rotation, and main synchronous pulley drives from synchronous belt wheeling driving gear and rotates, wheel and rack
Engagement, gear, gear rotation band carry-over bar is mobile, the mobile movement for realizing cutter on bearing inner race of rack gear, while in bearing
The movement of the rotation and cutter enclosed under jaw action is convenient for processing the circular channel of width on bearing inner race.
2, when servo motor rotates backward, by living synchronous pulley, moving cutter reversely from synchronous pulley and gear, rack gear
Dynamic, cutter reverse movement is processed on bearing inner race again, and the number of control servo motor positive and negative rotation moves back and forth rack gear,
Pumping for rack gear repeats to process on bearing inner race convenient for cutter, to increase the depth of concave convex groove, is needed
Want the channel of width and depth.
3, two rack gears are set, set that there are two cutter phases on each rack gear on uniform a cutter, with an existing rack gear
Compare, due to being provided with two rack gears, two rack gears fix a cutting tool and will not process in the same direction to bearing, avoid because
The scrap generated when the tool sharpening being located above falls in the processing on underlying cutter and influencing underlying cutter.
The setting of two cutters improves work efficiency simultaneously.
4, cam and servo motor are coaxially disposed, and pin shaft offsets with cam, and the cam center of circle and pin shaft distance are from recently to most
In remote process, the one end of push rod far from cam is pushed gradually to draw close to locking hole, when the cam center of circle and pin shaft apart from it is farthest when,
Pin shaft just into locking hole, make from synchronous pulley suspend rotate, from synchronous pulley suspend rotate while servo motor make
Gear also suspends rotation, so that the cutter on rack gear be made not continue to move, rack drives cutter is avoided to continue to move to make channel
Width is bigger, and cannot get qualified channel.
Further, clamping jaw is equipped with oil outlet, and rack is equipped with fuel tank, flowline is communicated between fuel tank and clamping jaw.
When clamping jaw clamps bearing inner race, the oil in fuel tank is entered in clamping jaw by flowline, then passes through going out on clamping jaw
Oilhole flows down on the retainer of bearing, oils to bearing.
Further, rack gear is oppositely arranged with Gear axis, and the cut surface of the cutter is reversed.
Rack gear is equipped with cutter, and two rack and pinion axis are oppositely arranged and make cutter also no longer on same plane, keep away
The scrap for exempting to generate when the tool sharpening bearing being located above is fallen on the cutter of lower section and cutter is to bearing below influencing
Processing.
Further, the modulus of the gear is greater than 1 and less than 3.
If the modulus of gear is greater than 3, when gear rotates, the mobile distance of rack gear is big, is not easy to the width of control channel；
If gear can not transfer power on rack gear when the modulus of gear is less than 1, rack gear can not move and just be unable to drive cutter
Mobile, cutter does not move the channel that width just can not be processed on bearing inner race.
Further, the cut surface width of the cutter is 2~3mm.
The cut surface width of cutter is set as 2~3mm, if the width of cutter is less than 2mm, cutter is once on bearing inner race
The width very little of the groove processed, the channel time that process width are long；If the width of cutter be greater than 3mm, cutter with
The contact area of bearing is big, and pressure is small, and processing effect is bad.
