Abstract

A structure to apply flexing to an object to test resilience to being bent has a first portion and a second portion. The structure includes a base, a rotating member, a pressing plate, and an adjusting assembly. The base defines first and second receiving grooves, and the second receiving groove receives the first portion. The rotating member on the base is partially received in the first receiving groove. An abutting surface of the rotating member is recessed to form a third receiving groove which receives the second portion. The pressing plate on the base presses against the first portion. The adjusting assembly controls the rotating member to rotate towards the base about a desired angle, thereby causing the second portion to be bent with respect to the first portion.

First claim

What is claimed is:

1. A bending fixture configured to bend an object, the object comprising a first portion and a second portion, the bending fixture comprising:
a base comprising a first receiving groove and a second receiving groove, the second receiving groove being configured to receive the first portion;
a rotating member rotatably connected to the base and partially received in the first receiving groove, the rotating member comprising an abutting surface facing the base, a portion of the abutting surface being recessed to form a third receiving groove, the third receiving groove being configured to receive the second portion;
a pressing plate detachably disposed on the base, and configured to press and fix the first portion in the second receiving groove; and
an adjusting assembly fixed on the base and connected to the rotating member, the adjusting assembly being configured to control the rotating member to rotate towards the base about a predetermined angle, thereby bending the second portion with respect to the first portion.

2. The bending fixture according to claim 1 , wherein the adjusting assembly comprises a first adjusting member and a second adjusting member, the rotating member is disposed between the first adjusting member and the second adjusting member, at least one of the first adjusting member and the second adjusting member comprises a first fixing block and a sliding block, the first fixing block comprises an arcuate slot, the sliding block is slidably connected in the arcuate slot, the rotating member is fixed on the sliding block.

3. The bending fixture according to claim 2 , wherein at least one of the first adjusting member and the second adjusting member further comprises a second fixing block and a fastener, the fastener extends through the second fixing block and the sliding block, and is configured to fixing the sliding block on the first fixing block and limit movements of the sliding block.

4. The bending fixture according to claim 2 , wherein the first fixing block comprises scale marks adjacent to the arcuate slot, each of the scale marks corresponds to an angle that the rotating member rotates with respect to the base.

5. The bending fixture according to claim 2 , wherein the first fixing block comprises scale marks adjacent to the arcuate slot, each of the scale marks corresponds to an angle that the rotating member rotates with respect to the base minus a rebounding angle of the object after bending.

6. The bending fixture according to claim 2 , wherein the rotating member comprises a first rotating plate and a second rotating plate arranged side by side, the first adjusting member is rotatably connected to the first rotating plate, the second adjusting member is rotatably connected to the second rotating plate.

7. The bending fixture according to claim 6 , wherein the first rotating plate and the second rotating plate are separated from each other.

8. The bending fixture according to claim 7 , wherein the first adjusting member is rotatably connected to the first rotating plate through a first rotating shaft, the second adjusting member is rotatably connected to the second rotating plate through second first rotating shaft.

9. The bending fixture according to claim 8 , wherein the first rotating shaft and the second rotating shaft are coaxial.

10. The bending fixture according to claim 6 , wherein a portion of the third receiving groove is disposed at the first rotating plate, another portion of the third receiving groove is disposed at the second rotating plate.

11. The bending fixture according to claim 1 , wherein a portion of the abutting surface is further recessed to form an avoidance groove, at least a portion of the pressing plate is received in the avoidance groove when the rotating member rotates towards the base, the third receiving groove is disposed at a bottom surface of the avoidance groove.

12. The bending fixture according to claim 1 , wherein at least one positioning columns protrudes from the base, the pressing plate comprises at least one through hole, and each of the at least one positioning column is configured to extend through one of the at least one through hole.

13. The bending fixture according to claim 1 , wherein the base and the pressing plate are connected to each other by a magnetic force.

14. The bending fixture according to claim 1 , wherein the base comprises a first surface, a second surface opposite to the first surface, a first sidewall, a second sidewall opposite to the first sidewall, a third sidewall, and a fourth sidewall opposite to the third sidewall; the first sidewall, the third sidewall, the second sidewall, and the fourth sidewall are connected in that order; the rotating member, the pressing plate, and the adjusting assembly are disposed on the first surface; the first surface is recessed towards the second surface to form the first receiving groove and the second receiving groove.

15. The bending fixture according to claim 14 , wherein the first receiving groove passes through the first sidewall, the second sidewall, and the fourth sidewall.

16. The bending fixture according to claim 14 , wherein the first surface is further recessed towards the second surface to form a fourth receiving groove, the fourth receiving groove is configured to receive a third portion of the object, the pressing plate is further configured to press and fix the third portion in the fourth receiving groove.

17. The bending fixture according to claim 1 , wherein the pressing plate comprises a third surface, a fourth surface opposite to the third surface, and a seventh sidewall connected between the third surface and the fourth surface; the fourth surface faces the base, the seventh sidewall faces the rotating member; the pressing plate further comprises a first pressing block protruding from the fourth surface, the first pressing block is configured to press the first portion in the second receiving groove.

18. The bending fixture according to claim 17 , wherein the pressing plate further comprises a second pressing block and a third pressing block protruding from the seventh sidewall, the third pressing block and the first rotating plate are configured to cooperatively press and fix the second portion in the third receiving groove.
