Keep off insetting case technology.I.e. after rotor bearing, which is kept off, to wear, it is only necessary to which replacing axle sleeve can.Axle sleeve belongs to thin-wall part, in axle sleeve
Outer circle need to plate hard chrome to realize wear-resisting functions.The technique for producing diving generator rotor axis axle sleeve in the prior art, is by one
Secondary to be loaded, then roughing more than one piece axle sleeve is cut off again with guaranteeing the position of related features of axle sleeve inner circle and outer circle.Due to existing skill
Most of axle sleeve used in art is all wall thickness for the thin-wall part of 2.5mm, so can not clamping.Common practice is all without plating
Preceding mill, but directly to axle sleeve plate hard chrome, then reheating is attached to plated on axis after grind.Due to the surface smoothness ground after plating
Difference, uneven coating is even, causes the sliding effect between the axle sleeve and bearing during subsequent production bad, can not guarantee product
The requirement of processing technology, because axle sleeve abrasion makes motor reduced service life in motor use process.
Summary of the invention
The utility model provides a kind of can be realized and plates preceding grinding process to overcome the shortcomings of the prior art
Machining mould is ground before plating for diving generator rotor axis axle sleeve.
The utility model is achieved through the following technical solutions: a kind of to add for the preceding mill of diving generator rotor axis axle sleeve plating
Work mould, mill machining mould is total to three parts by support device, liftout attachment and press-in device and forms before the plating；Support device is one
Root conical core shaft is respectively arranged with the first thread segment and the second thread segment at the both ends of conical core shaft, the first of conical core shaft
There are the axle sleeve spaces that can be arranged diving generator rotor axis axle sleeve between thread segment and the second thread segment；Liftout attachment is by ejecting
Nut and the ejection sleeve on the inside of ejection nut are welded to form, and the first thread segment screw thread for ejecting nut and conical core shaft connects
It connects；Press-in device is the locking nut with boss being processed by thick hexagonnut, the second of locking nut and conical core shaft
Thread segment is threadedly coupled.
Conical core shaft is the conical core shaft that taper is 1:2500.Conical core shaft can guarantee the coaxial pass of connected part well
System, to better ensure that the concentric of connected part, conical core shaft is to generate frictional force by the conical surface to transmit torque, therefore taper core
Axis is generally used for the occasion of high speed light loading and high transmission accuracy.
It ejects nut and thick hexagonnut is all M40 hex nut.The ruler of the M40 hex nut used in the utility model
Very little is high 6cm, internal diameter 4cm, outer diameter 6cm, the hex nut that flight pitch is 0.02mm.M40 hex nut using it is good not
Rust steel be made, have good resistance to acid and alkali, and have the characteristics that hardness by force and shock resistance, mantle friction is big, can be fine
Fitted closely with the thread segment in conical core shaft, be conducive to ensure machining mould stability.
The mesoporous of support device and diving generator rotor axis axle sleeve uses nitril shaft system of fits.Nitril shaft system of fits refers to substantially partially
Difference is the tolerance range of certain axis, and a kind of system of various cooperations is formed from the tolerance range in the hole of different basic deviations.
The beneficial effects of the utility model are: to solve the problems, such as mill before axle sleeve plating, spy is designed in the utility model
Machining mould is ground before plating for diving generator rotor axis axle sleeve, this set mould realizes the problem ground before the plating of armature spindle axle sleeve, together
When solve the problems, such as that chrome layer is non-uniform, avoid rotor axis of electric axle sleeve and caused in use because uneven coating is even
Abrasion, improve the service life of motor.
The utility model has the further advantage that this set mould for mill machining mould before the plating of diving generator rotor axis axle sleeve
Become moving along a straight line by the rotary motion of nut, realizes torque and be converted into linear thrust, power transmission is uniform, makes axle sleeve uniform
Stress condition under be loaded upper processing in defined position, solve axle sleeve generated after by external force deformation, burr the defects of.
The processing technology ground before axle sleeve plating is realized, the requirement of product processing technique is ensure that, improves product quality and service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of mill machining mould before the plating of the utility model diving generator rotor axis axle sleeve；
In figure: 1- locking nut；2- conical core shaft；The first thread segment of 3-；The second thread segment of 4-；5- diving generator rotor axis
