Method of making a load sensor plate
View Patent ↗A load sensor plate ( 100 ) is adapted for manufacture by stamping spaced apart openings ( 110 ) through a thin blank to define flexure beams ( 112 ) beside the openings ( 110 ); and forming the blank with spaced apart columnar walls ( 102 ), ( 106 ) joined by a web ( 104 ) having the openings ( 110 ) and the flexure beams ( 112 ) whereby, an applied load ( 116 ) exerted on one of the columnar walls ( 102 ) is distributed among the flexure beams ( 12 ), and another of the columnar walls ( 106 ) bears an opposing force ( 118 ) that resists the applied load ( 118 ).
1. A method of making a load sensor plate, comprising:
stamping spaced apart openings through a blank of resiliently deformable material to define flexure beams beside the openings;
forming the blank with spaced apart columnar walls having a form resembling a cylinder joined by a web having the openings and the flexure beams wherein, an applied load exerted on one of the columnar walls is distributed among the flexure beams, and another of the columnar walls bears an opposing force that resists the applied load.
2. The method of claim 1 , further comprising:
forming the blank as a strip connecting with the load sensor plate.
3. The method of claim 1 , further comprising:
stamping the blank to form an outer periphery of the load sensor plate.
4. The method of claim 1 , further comprising:
forming said blank to provide said one of the columnar walls with a base to bear the applied load.
5. The method of claim 1 , wherein said blank is so formed that an outer one of said columnar walls is circumferential about the web.
6. The method of claim 1 , wherein said blank is so formed that the web is circumferential about an inner one of said columnar walls.
7. The method of claim 6 , wherein said blank is so formed that an outer one of said columnar walls is circumferential about the web.
8. A method of making a load sensor plate for detecting strain comprising:
stamping spaced apart openings through a blank of resiliently deformable material to define flexure beams beside the openings;
forming the blank with spaced apart columnar walls joined by a web having the openings and the flexure beams whereby, an applied load exerted on one of the columnar walls is distributed among the flexure beams, and another of the columnar walls bears an opposing force that resists the applied load; and
applying strain detecting sensors on the flexure beams to detect the applied load.
9. The method of claim 8 , further comprising:
connecting the sensors to a circuit board; and
connecting an electrical cable to the circuit board.
10. A method of making a load sensor plate, comprising:
stamping spaced apart openings through a blank of resiliently deformable material to define flexure beams beside the openings;
forming the blank with spaced apart columnar walls joined by a web having the openings and the flexure beams; and
forming the blank to provide said one of the columnar walls with a base to bear the applied load; and
forming said one of the columnar walls and said base as a cup; and
forming the cup with a central projection to receive the applied load as an off axis applied load.
