[0025] Through the above technical scheme, through the setting of the concentricity self-test component 6, the concentricity can be tested at the same time as the torque detection, so as to effectively avoid the problem of excessive detection error caused by poor concentricity. Further, the present application designs an adjustable clamping jaw component 7.

The rotating ring 601 is arranged on the arc-shaped outer wall of the circular cylinder 501 of the torque sensor and is rotatably connected to the circular cylinder 501. A plurality of connecting frames 602 are fixedly arranged on the arc-shaped outer wall, and a rectangular connecting column 603 is fixedly connected to one end of the connecting frame 602, and a rectangular sleeve 604 is fixedly connected to the bottom end of the rectangular connecting column 603. A contact plate 605 is slidably connected in the inner cavity of the rectangular sleeve 604, and the front end of the contact plate 605 is arc-shaped. Through the technical solution, when the device clamps the knob, the front end of the contact plate 605 can be in contact with the outer wall of the knob at the same time; The other end of the contact plate 605 is an inclined surface, and a slider A606 is slidably connected in the inner cavity of the rectangular connecting column 603, and a slope block 607 is fixedly connected at the bottom end of the slider A606, and the bottom slope of the slope block 607 contacts the slope of the contact plate 605.

A rack A609 is fixedly connected to the upper surface of the slider A606, and a rotating shaft 610 is rotatably connected in the inner cavity of the rectangular connecting column 603, and the arc wall of the rotating shaft 610 A small gear 611 is fixedly connected at the rectangular connecting column 603, and the small gear 611 and the rack A609 are meshed with each other. A large gear 612 is fixedly connected to the arc wall of the rotating shaft 610. A slider B614 is slidably connected in the inner cavity of the rectangular connecting column 603. A rack B613 is fixedly connected to the bottom surface of the slider B614, and the rack B613 and the large gear 612 are meshed with each other. One end of an indicator rod 615 is fixedly connected to the upper surface of the slider B614, and the other end of the indicator rod 615 passes through the upper wall of the inner cavity of the rectangular connecting column 603 and extends outside the wall. Through the technical solution, when the concentricity self-test component 6 rotates, So that one end of the contact plate 605 rotates along the arc-shaped outer wall of the knob. When the concentricity of the device when clamping the knob is not good, when the contact plate 605 rotates along the outer wall of the knob, the eccentricity of the knob causes the contact plate 605 to move. The movement of the contact plate 605 can push the inclined block 607 to move, thereby driving the slider A606 to move. The movement of the slider A606 can drive the rack A609 to move, thereby driving the small gear 611 to rotate, and then driving the large gear 612 to rotate. The rotation of the large gear 612 can drive the rack B613 to move. Since the large gear 612 is directly The diameter is larger than the diameter of the pinion 611, so that when the rack A609 moves a small distance, it can drive the rack B613 to move a longer distance, realizing the function of displacement amplification, so that the movement of the rack B613 can drive the indicator rod 615 to move, so that the staff can judge whether the concentricity is poor by observing the movement of the indicator rod 615. If the indicator rod 615 has no obvious up and down movement during the rotation, that is, the concentricity is good, and data can be recorded. If the indicator rod 615 has obvious up and down movement during the rotation, the concentricity is poor, and the clamping position needs to be readjusted or adjusted.

The output torque is measured, and the torque detection function is realized. At the same time, when the rotating rod 3 rotates, the fourth gear 620 can be driven to rotate, and then the third gear 619 can be driven to rotate. The rotation of the third gear 619 drives the rotating rod 617 to rotate, thereby driving the second gear 618 to rotate, and then driving the first gear 616 to rotate, thereby driving the rotating ring 601 to rotate. At the same time, the diameter of the second gear 618 is larger than the diameter of the first gear 616, and the diameter of the fourth gear 620 is larger than the diameter of the third gear 619, thereby realizing the rotation function of the concentricity self-test component 6, and making the concentricity self-test component 6 rotate faster relative to the knob, thereby achieving the effect of moving the contact plate 605 along the outer wall of the knob, and realizing the automatic detection function.
