Description
Technical field
The present invention relates to bearing shell manufacture field, and in particular to a kind of application method of expansion type bearing shell mobile device.
Background technology
Axial workpiece has been typically transmitting torque effect, and leading in junction can use to bearing shell.But in bearing shell
In process, it usually needs by operations such as some turning, the grindings that arrange, the inwall especially for bearing shell is processed, generally
It is required for carrying out grinding work.Due to the characteristic of bearing shell itself, overall is in semi-cylindrical, after grinding is finished, in mobile when ratio
It is cumbersome.If because directly using clamping bearing shell outer wall, it is possible to occur, because chucking power is spent greatly, cause bearing shell to become
Shape.But directly the side wall of clamping bearing shell is moved, the inwall of bearing shell may be crushed.It is main still to bearing shell at present
Carry out based on outer wall clamping, in order to avoid chucking power is spent greatly in clamping process, reset bullet is installed generally between two clamping jaws
Spring, to solve the problems, such as the bad control of clamping dynamics, but is but present in clamping process, and the situation hair for dropping easily occurs in bearing shell
It is raw.
The content of the invention
It is avoided that inner surface of bearing bush is scratched it is an object of the invention to provide one kind, and is not in bearing shell in moving process
The moving method for dropping.
To reach above-mentioned purpose, base case of the invention is：The application method of expansion type bearing shell mobile device, including with
Lower step：
The first step, origin reference location：Air pressure valve is closed, cyclic spring capsule is in non-expansion state；Air pressure cylinder working, piston rod is from gas
Stretched out in the cylinder barrel of cylinder pressure, grip slipper bearing shell is moved to piston rod where circle center at；
Second step, pressurization clamping：Air pressure valve is opened, pneumatic cylinder works on, and grip slipper is close to the inner surface of bearing shell, annular elastomeric
Property capsule gradually expands；When the elastic-friction ball on cyclic spring capsule is contacted with the inner surface of bearing shell, during elastic-friction deformation of ball, close
Hold one's breath pressure valve；
3rd step, mobile bearing shell：Pneumatic cylinder works on, and bearing shell moves to specified location with cyclic spring capsule；
4th step：Fixture resets：Open air pressure valve, then pneumatic cylinder is reversely operated, cyclic spring capsule shrink, cyclic spring capsule with
Bearing shell is separated, and piston rod is recovered in the steel cylinder of pneumatic cylinder.
The advantage of this programme is：It is pneumatic cylinder using same dynamical system, on the one hand saves power-equipment, it is another
Aspect reduces taking up room for package unit.This programme is expanded by cyclic spring capsule, causes the bullet of cyclic spring capsule outer surface
Frottage ball is contacted with the inner surface of bearing shell, and when elastic-friction deformation of ball, elastic-friction ball is contacted closely with bearing shell, and elasticity is rubbed
Wipe ball and use frictional connection mode with bearing shell.Due to elastic-friction ball, the elasticity of itself overcomes rigid contact and produces scuffing work
The problem of part.In addition, elastic-friction ball deforms, it is sufficient to embody contact connection of the elastic-friction ball with bearing shell.In axle
Watt moving process in, bearing shell will not drop from cyclic spring capsule easily.
Preferred scheme one：Based on scheme preferred scheme, second step, pressurization clamping the step of in, cyclic spring capsule
Gradually expand, the pressure increase in airtight chamber, guide post stretches out from pilot hole, makes on the bottom of guide post and operating desk
Gathering sill is contacted.In the moving process of bearing shell, by guide post, the accuracy of bearing shell movement is more increased, will be original
Cantilever design is changed into 2 supporting constructions, and in reducing moving process, appearance is rocked.
Preferred scheme two：Preferably one preferred scheme：In the step of second step, pressurization clamping, elastic-friction
Deformation of ball, gas is extruded in friction groove, forms negative pressure trough.The advantage of this programme is that elastic-friction ball is provided with friction
Groove increased the contact performance of elastic-friction ball and inner surface of bearing bush.
