Problems solved by technology

The disadvantage of using this method to test the torque is that relying on manual work, human factors have a relatively large impact on the measurement structure, resulting in low accuracy and efficiency in measuring the torque of the hinge

Embodiment Construction

[0083] see figure 1 and figure 2, the torque testing device 100 according to the preferred embodiment of the present invention is used to measure the torque of the hinge 200 . The hinge 200 includes a fixing part 210 and a rotating part 230 rotatable relative to the fixing part 210 . The torque testing device 100 includes a mounting base 10 , a driving mechanism 20 , a telescoping mechanism 30 , a chuck 40 , an adjusting mechanism 50 , a hinge mounting base 60 and a testing mechanism 70 fixedly connected to the hinge mounting base 60 . The fixing part 210 of the hinge 200 is fixed on the hinge mounting seat 60; the rotating part 230 is clamped by the clamp 40; the driving mechanism 20 drives the rotating part 40 to rotate the rotating part 230 and to the The fixing member 210 exerts force; the testing mechanism 70 tests the torque of the hinge 200 through the force borne by the hinge mounting base 60 and the fixing member 210 . The adjusting mechanism 50 is used for adjust...

Abstract

The invention discloses a torque testing device for testing the torque of a hinge. The hinge includes a fixed piece and a rotating piece capable of rotating relative to the fixed piece; the torque testing device includes a driving mechanism, a clamp head, a hinge mounting seat and a testing mechanism fixedly connected with the hinge mounting seat; the fixed piece is fixed on the hinge mounting seat; the clamp head fixedly clamps the rotating piece; the driving mechanism drives the clamp head to rotate so as to drive the rotating piece to rotate and exerts force on the fixed piece; and the testing mechanism tests the torque of the hinge through the force borne by the fixed piece and the hinge mounting seat. The torque testing device has rather high testing precision.

Description

technical field [0001] The present invention relates to a torque testing device, in particular to a torque testing device for testing the torque of a hinge. Background technique [0002] Common flip-type electronic devices such as mobile phones, personal digital assistants (personal digital assistants, PDAs) and notebook computers, etc. all include a body and a flip, the flip is rotatably mounted on the body through a hinge, and the torque is the flip-type electronic device One of the most important mechanical performance parameters of hinges is also one of the main parameters referenced by manufacturers for qualitative classification and customer selection, so the torque must be tested during the manufacturing process. The current general torque test method is to use a push-pull force meter to apply force to the hinge at a certain moment arm position to make it move, so that the maximum torque value measured in a specific process is used as the qualitative standard of the h...
