System and method for testing a clamping force
View Patent ↗A system for testing a clamping force includes a lever, a base, and a sensor, The lever is coupled to a pivot and moves about the pivot. The lever includes a first end and a second end on opposites sides of the pivot. The base receives a first tip of a clamp and maintains a fixed position relative to the pivot. The second end of the lever receive a second tip of the clamp and moves relative to the base and the pivot as the first tip and the second tip of the clamp move towards one another. The sensor measures a first force applied by the first end of the lever. The first force is proportional to a second force applied to the second end of the lever by the clamp.
1. A system for testing a clamping force, comprising:
a lever coupled to a pivot and operable to move about the pivot, the lever comprising a first end and a second end on opposites sides of the pivot;
a base operable to receive a first tip of a clamp and to maintain a fixed position relative to the pivot, wherein the second end of the lever is operable to receive a second tip of the clamp and to move relative to the base and the pivot as the first tip and the second tip of the clamp move towards one another; and
a sensor operable to measure a first force applied by the first end of the lever, wherein the first force is proportional to a second force applied to the second end of the lever by the clamp.
2. The system of claim 1 , wherein the sensor is a load cell operable to measure the first force applied by the first end of the lever pushing against the load cell.
3. The system of claim 1 , wherein the sensor is strain gauge operable to measure the first force applied by the first end of the lever pulling away from the strain gauge.
4. The system of claim 1 , wherein the pivot is substantially midway between a first contact point where the first end of the lever is coupled to the sensor and a second contact point where the second end of the lever receives the second tip of the clamp.
5. The system of claim 1 , wherein the pivot is located nearer to a first contact point where the first end of the lever is coupled to the sensor than to a second contact point where the second end of the lever receives the second tip of the clamp.
6. The system of claim 1 , wherein the pivot is located further from a first contact point where the first end of the lever is coupled to the sensor than from a second contact point where the second end of the lever receives the second tip of the clamp.
7. The system of claim 1 , further comprising a processor operable to receive a measurement of the first force from the sensor and to calculate the second force applied to the second end of the lever by the clamp.
8. The system of claim 1 , further comprising a processor operable to receive a measurement of the first force from the sensor and to determine whether the measurement falls within an acceptable range, the processor further operable to trigger an event in response to determining that the measurement falls outside the acceptable range.
9. The system of claim 8 , wherein the event comprises generating an automatic notice that the measurement falls outside the acceptable range.
10. The system of claim 8 , wherein the event comprise disabling the clamp.
11. A method of testing a clamping force, comprising:
receiving a first tip of a clamp at a base that is operable to maintain a fixed position relative to a pivot of a lever, the lever comprising a first end and a second end on opposite sides of the pivot;
receiving a second tip of a clamp at the second end-of the lever; and
measuring a force at the first end of the lever, wherein the measured force at the first end of the lever is proportional to a clamping force applied to the second end of the lever by the clamp.
12. The method of claim 11 , wherein measuring the force at the first end of the lever further comprises using a load cell to measure the force applied by the first end of the lever pushing against the load cell.
13. The method of claim 11 , wherein measuring the force at the first end of the lever further comprises using a strain gauge to measure the force applied by the first end of the lever pulling away from the strain gauge.
14. The method of claim 11 , wherein the pivot of the lever is substantially midway between a first contact point where the first end of the lever is coupled to a sensor for measuring the force at the first end of the lever and a second contact point where the second end of the lever receives the second tip of the clamp.
15. The method of claim 11 , wherein the pivot of the lever is located nearer to a first contact point where the first end of the lever is coupled to a sensor for measuring the force at the first end of the lever than to a second contact point where the second end of the lever receives the second tip of the clamp.
16. The method of claim 11 , wherein the pivot of the lever is located further from a first contact point where the first end of the lever is coupled to a sensor for measuring the force at the first end of the lever than from a second contact point where the second end of the lever receives the second tip of the clamp.
17. The method of claim 11 , further comprising calculating the clamping force applied to the second end of the lever by the clamp using the measurement of the force at the first end of the lever.
18. The method of claim 11 , further comprising:
determining whether the measurement of the force at the first end of the lever falls within an acceptable range; and
triggering an event in response to determining that the measurement falls outside the acceptable range.
19. The method of claim 18 , wherein the event comprises generating an automatic notice that the measurement falls outside the acceptable range.
20. The method of claim 18 , wherein the event comprise disabling the clamp.
