Remoldable contour sensor holder
View Patent ↗A sensor assembly for inspecting a part, the sensor assembly comprising a sensor for sensing a defect of the part and a remoldable housing for retaining and positioning the sensor in alignment with the defect of the part. The housing is formed of a moldable material and may be molded into a shape that conforms to a contour of the part when a stimulus is applied to the housing and may harden into the shape when the stimulus is removed from the housing.
1. A sensor assembly for inspecting a part, the sensor assembly comprising:
a sensor for sensing a defect of the part;
a remoldable housing for retaining and positioning the sensor in alignment with the defect of the part, the remoldable housing being formed of a moldable material that is:
molded into a shape that forms a cavity and conforms to a contour of the part when a stimulus is applied to the remoldable housing, the cavity extending completely through the remoldable housing and having a first end opening for receiving at least a portion of the sleeve and at least a portion of the sensor therein and a second end opening for allowing a sensing signal to pass therethrough; and
hardened into the shape when the stimulus is removed from the remoldable housing; and
a sleeve having a first opening for receiving at least a portion of the sensor therein and a second opening for transmitting or receiving the sensing signal therethrough, the sleeve being configurable to be positioned at least partially inside the cavity.
2. The sensor assembly of claim 1 , wherein the remoldable housing is configurable to be remolded until the sensor is at an optimal position for sensing the defect.
3. The sensor assembly of claim 1 , further comprising:
a thin layer of material configured to overlay the second opening for preventing the remoldable housing from entering the sleeve when the sleeve is inserted into the cavity, the thin layer of material being configurable to be at least partially removed when the sleeve is at least partially in the cavity.
4. The sensor assembly of claim 1 , wherein the second opening is on a non-chamfered end of the sleeve.
5. The sensor assembly of claim 1 , wherein the remoldable housing is further configurable to receive a couplant for improving the signal.
6. The sensor assembly of claim 1 , further comprising a stimulus source integrated with the remoldable housing, the stimulus source being configurable to apply the stimulus to the remoldable housing.
7. The sensor assembly of claim 6 , wherein the stimulus source is embedded in the remoldable housing.
8. The sensor assembly of claim 1 , wherein the stimulus is heat.
9. A method for inspecting a part, the method comprising the steps of:
applying a stimulus to an at least partially remoldable housing;
molding the at least partially remoldable housing to form a cavity extending completely through the remoldable housing and having a first end opening for receiving at least a portion of a sleeve and at least a portion of a sensor therein and a second end opening for allowing a sensing signal to pass therethrough;
positioning the sleeve at least partially in the cavity;
placing the sensor at least partially in the sleeve such that the sensor extends at least partially into the cavity;
molding the at least partially remoldable housing to conform to a contour of the part such that the sensor is at a position to transmit or receive a signal for sensing a defect of the part;
detecting the signal;
remolding the at least partially remoldable housing into a modified shape for repositioning the sleeve and the sensor until an optimized signal is achieved; and
removing the stimulus to harden the at least partially remoldable housing into the modified shape.
10. The method of claim 9 , further comprising the step of forming the at least partially remoldable housing from a supply of shape memory material.
11. The method of claim 9 , further comprising the step of:
remolding the at least partially remoldable housing into a second modified shape when the contour changes to maintain the optimized signal.
12. A sensor assembly for inspecting a part, the sensor assembly comprising:
a sensor for sensing a defect of the part;
a remoldable housing for retaining and positioning the sensor in alignment with the defect of the part, the remoldable housing being formed of a moldable material that may:
be molded into a shape that forms a cavity for receiving at least a portion of the sensor therein and conforms to a contour of the part when a stimulus is applied to the remoldable housing; and
harden into the shape when the stimulus is removed from the remoldable housing;
a sleeve having a first opening for receiving at least a portion of the sensor therein and a second opening for allowing a sensing signal to be transmitted or received therethrough, the sleeve being configurable to be positioned at least partially inside the cavity; and
a thin layer of material configured to overlay the second opening of the sleeve for preventing the remoldable housing from entering the sleeve when the sleeve is inserted into the cavity, the thin layer of material being configurable to be at least partially removed when the sleeve is at least partially in the cavity.
13. A sensor assembly for inspecting a part, the sensor assembly comprising:
a sensor for sensing a defect of the part;
a remoldable housing for retaining and positioning the sensor in alignment with the defect of the part, the remoldable housing being formed of a moldable material that may:
be molded into a shape that forms a cavity and conforms to a contour of the part when a stimulus is applied to the remoldable housing, the cavity extending through the remoldable housing and having a first end for receiving at least a portion of the sensor therein and a second end for allowing a sensing signal to pass therethrough; and
harden into the shape when the stimulus is removed from the remoldable housing;
a sleeve having a first opening for receiving at least a portion of the sensor therein and a second opening for transmitting or receiving a sensing signal therethrough, the sleeve being configurable to be positioned at least partially inside the cavity; and
a thin layer of material configured to overlay the second opening for preventing the remoldable housing from entering the sleeve when the sleeve is inserted into the cavity, the thin layer of material being configurable to be at least partially removed when the sleeve is at least partially in the cavity.
