Patent number: 11602824Abstract: Some embodiments of the present disclosure provide an adjustable torque clamping fixture, including a clamping body driven by a threaded rod to move and used for clamping an object. The threaded rods implements an axial movement thereof by means of screw thread transmission. An adjustable torque handle is configured at the rear end of the threaded rod. The maximum clamping force is adjusted by the adjustable torque handle. When the maximum clamping force is attained, continued application of a torque on the threaded rod by the handle results in slippage, so that no larger clamping force can be applied, thus implementing precision clamping, and preventing the clamped object from being damaged by an excessive torque. The adjustable torque clamping fixture overcomes the shortcoming of a manual clamping fixture known to inventors of which the magnitude of the clamping force is difficult to determine during use.Type: GrantFiled: December 25, 2019Date of Patent: March 14, 2023Assignees: HANGZHOU UNITED ELECTRIC MANUFACTURE CO., LTD., HANGZHOU GREAT STAR INDUSTRIAL CO., LTD.Inventor: Yueming Li
