Abstract
An automatable joint forming apparatus and process for leak resistance assembly of a flexible fluid conduit to a rigid fluid conduit including insertion of the rigid conduit and a sliding shape conforming die.
Claims21
A tooling system for automated co-axial assembly comprising:
- (a) a first cylindrical flexible fluid conduit having:
- i. a first inline fluid-transfer nominally cylindrical bore with a corresponding central first fluid conduit axis,
- ii. a nominally cylindrical first outer surface, and,
- iii. a first free end,
- (b) a second cylindrical fluid conduit having:
- i. a second inline fluid-transfer bore with a corresponding central second fluid conduit axis, and,
- ii. a nominally cylindrical second outer surface, and
- iii. a free end, wherein the second outer surface including a nominal diameter adapted to engage circumferentially with the first inline fluid-transfer bore,
- (c) in an overlapping fluid-leak-resisting relationship between the first fluid transfer bore and the second outer surface,
- (d) a female die component adapted, when engaged with the outer surface of the first fluid conduit during the assembly process:
- i. to confine the shape of the outer surface of the first free end within its nominally cylindrical shape, and,
- ii. to confine the first fluid conduit axis at the first free end to the center of its nominally cylindrical shape and its bore along a substantially straight line, and,
- iii. to provide a sliding interference fit between the female die component and the first outer surface,
- and
- (e) a guiding mechanism adapted, when engaging with and guiding either or both of the first and the second fluid conduits:
- i. to confine the first and second fluid conduit axes to axial end-to-end alignment with each other,
- ii. to axially present the free end of the fluid conduits to each other,
- and,
- (f) a pressing mechanism adapted both:
- i. to drive the second outer fluid conduit surface into the first fluid transfer bore,
- and,
- ii. to simultaneously drive the female die component away from the first free end along the first fluid conduit axis.
