Embodiment Construction
[0023] Embodiment 1 of a torque wrench verification device is as Figure 1~3 Shown: It includes a detection table and a wrench loading assembly, a standard torque sensor 9 is fixed on the detection table, and the detection end of the standard torque sensor 9 is an inner square hole structure. The torque wrench verification device also includes a load mechanism. The load mechanism includes a relatively rotatable first grinding-in piece 3 and a second grinding-in piece 4. In this embodiment, the first grinding-in piece is screwed to the second grinding-in piece. The first grinding-in piece is equivalent to The bolt, the second running-in piece is equivalent to a nut, the upper end of the first running-in piece is the outer square head 6 of the first running-in piece, and the outer square head 6 of the first running-in piece is used to stop the rotation with the torque output sleeve 2 of the verified torque wrench Mating, and the first running-in square head can move up and down ...

The invention relates to a torque wrench calibrating device and a loading assembly thereof. The torque wrench calibrating device comprises a detection table and the loading assembly, wherein a standard torque sensor is arranged on the detection table; the loading assembly comprises an arc-shaped guide structure and a bracket force applying mechanism; the center of circle of the arc-shaped guide structure is coaxial with the detection end of the standard torque sensor; the arc-shaped guide structure is connected with a wrench grip bracket in a guiding way, the rotation axis of the wrench grip bracket is parallel with the axis of the detection end of the standard torque sensor, and the wrench grip bracket is used for driving a wrench handle to move; the bracket force applying mechanism is used for driving the wrench grip bracket to guide and move along the arc-shaped guide structure. The torque wrench calibrating device can solve the problem of poor simulation degree in the calibrating process due to nonverticality between the wrench force applying direction and the wrench handle in the prior art.
Description
technical field [0001] The invention relates to a torque wrench verification device and a loading assembly thereof in the field of verification. Background technique [0002] At present, in the production and manufacturing process of bolt assembly, it is necessary to ensure that the bolt tightening force must be kept within the range specified by the national standard. It is very important whether the torque wrench used to assemble the bolt itself is accurate or not. The torque sensor is verified. Existing torque wrench verification devices such as the "manual torque wrench verification instrument" disclosed in Chinese patent CN205262672U, the torque wrench verification instrument includes a detection platform with a standard torque sensor, a force measuring component and a loading component. The testing platform includes a housing and The torque acquisition board assembly and the torque processing board assembly are connected by electrical signals. The loading assembly inc...
