Clamp and method of use
A clamp and method of use may be configured to detect whether a clamp is properly secured to an object, and whether that proper securement is maintained. One embodiment of a clamp may include a first portion and a second portion. The relative positions of the first and second portions may be selectively adjusted using a positioner. A sensor assembly may be secured between said first and second portions to determine if the first portion engages the work piece with the proper force. Multiple clamps may be used on a single work piece, and those clamps may be in communication with a common controller to alert the user when any clamp experiences a force other than the force the user desires.
1. A clamp comprising:
a. a first portion with an aperture formed therein;
b. a second portion with an anchor receiver formed therein, wherein said first portion is moveable with respect to said second portion in at least one dimension;
c. a positioner cooperatively engaged with said first and second portions, wherein said positioner includes a positioner anchor cooperatively engaged with said anchor receiver and a positioner adjuster adjacent said first portion, and wherein said positioner is configured so that a user may adjust the relative position of said first portion with respect to said second portion via said positioner adjuster; and
d. a sensor assembly secured between said first and second portions, wherein said sensor assembly detects whether said clamp experiences a force between said first and second portions at a predetermined magnitude.
2. The clamp according to claim 1 wherein said sensor assembly is further defined as comprising:
a. a biasing member configured to bias said first portion away from said second portion with a predetermined force;
b. a pin affixed to said first portion; and,
c. a proximity sensor affixed to said second portion, wherein said proximity sensor is configured to detect the presence of said pin at a predetermined distance from said proximity sensor.
3. The clamp according to claim 2 wherein said biasing member is further defined as a spring.
4. The clamp according to claim 2 wherein said biasing member is further defined as a Belleville washer.
5. A clamp comprising:
a. a first portion having a distal end, wherein an aperture is formed therein adjacent said distal end;
b. a pin engaged with said first portion opposite said distal end, wherein said pin extends away from said first portion;
c. a second portion with an anchor receiver formed therein, wherein a interface chamber is formed in said second portion such that said interface chamber corresponds to a distal end of said pin, wherein a sensor chamber is formed in said second portion such that said sensor chamber is positioned generally below said interface chamber; and wherein said first portion is moveable with respect to said second portion in at least one dimension along the longitudinal axis of said pin;
d. a positioner cooperatively engaged with said first and second portions, wherein said positioner includes a positioner anchor cooperatively engaged with said anchor receiver and a positioner adjuster adjacent said first portion, and wherein said positioner is configured so that a user may adjust the relative position of said first portion with respect to said second portion via said positioner adjuster; and
e. a sensor assembly secured between said first and second portions, wherein said sensor assembly detects whether said clamp experiences a force between said first and second portions at a predetermined magnitude.
6. The clamp according to claim 1 wherein said sensor assembly is further defined as comprising:
a. a biasing member configured to bias said first portion away from said second portion with a predetermined force;
b. a pin affixed to said first portion; and,
c. a proximity sensor affixed to said second portion, wherein said proximity sensor is configured to detect the presence of said pin at a predetermined distance from said proximity sensor.
7. The clamp according to claim 6 wherein said biasing member is further defined as a spring.
8. The clamp according to claim 5 wherein said sensor assembly is further defined as a strain gauge.
9. The clamp according to claim 7 wherein said anchor receiver and said sensor chamber are generally positioned at opposite ends of said second portion.
10. The clamp according to claim 5 wherein said sensor assembly is in communication with a controller.
11. The clamp according to claim 6 wherein said sensor assembly is in communication with a controller.
12. The clamp according to claim 5 wherein said first portion further comprises a pin extending toward said sensor.
13. The clamp according to claim 6 wherein said first portion further comprises a pin extending toward said sensor.
14. The clamp according to claim 5 wherein said sensor is further defined as a proximity sensor.
15. The clamp according to claim 6 wherein said sensor is further defined as a proximity sensor.
16. The clamp according to claim 5 wherein compression of said biasing member a predetermined amount confirms the presence of said pin confirming said clamp is properly secured to an object positioned within said clamp.
