Description

Technical Field

[0001] This utility model relates to the field of lever arm tooling technology, and in particular to a lever arm tooling for adjusting bolts of passive yaw calipers. Background Technology

[0002] Traditional lever arm fixtures have significant shortcomings in the operation of yaw passive yaw caliper adjusting bolts. They lack an independent fixing structure when the handle and lever are in critical positions such as tangential or perpendicular, requiring additional fixing, which is cumbersome and inconvenient in confined spaces. Furthermore, they are prone to accidental rotation due to vibration, affecting adjustment accuracy and safety. Simultaneously, the rigid connection allows a large amount of vibration to be transmitted to the handle, leading to operator fatigue and component loosening. The lever's torque resistance is weak, easily bending under stress during different rotational operations, reducing force transmission efficiency and adjustment effect, and even damaging the fixture. These problems make it difficult to meet the demands of efficient and precise operation. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a lever arm tooling for adjusting bolts of passive yaw calipers. Grooves are provided on both sides of the bottom end of the handle, and rubber semicircular blocks are provided on the inner side wall of the rotating frame. Three semicircular blocks are arranged in an array around the connection between the handle and the lever. The semicircular blocks match the grooves, and can engage the handle when the handle is tangential and perpendicular to the rotating frame, without the need for additional handle fixing. This facilitates the rotation of the lever and its lower components, and also reduces the transmission of vibration. Anti-rotation plates and anti-torsion plates are provided on the upper surface of the connecting frame, which can respectively improve the lever's resistance to torque and torque, so that the lever can maintain the device's adjustment effect on the bolt when used in different rotation modes, and prevent the lever from bending.

[0004] This utility model also provides a lever arm tooling with the above-mentioned type of yaw passive yaw caliper adjusting bolt, comprising: a drive head, a connecting frame rotatably connected to the side surface of the drive head, a lever fixedly connected to the upper surface of the connecting frame, an anti-rotation plate fixedly connected to the inner side wall of the lever, and an anti-torsion plate fixedly connected to the side surface of the anti-rotation plate; a rotating frame, a semi-circular block fixedly connected to the inner side wall of the rotating frame, a handle rotatably connected to the inner side wall of the rotating frame, a groove provided at the bottom end of the handle, and a rubber sleeve fixedly connected to the side surface of the handle. The above components include grooves on both sides of the bottom of the handle and rubber semicircular blocks on the inner wall of the rotating frame. Three semicircular blocks are arranged in an array around the connection between the handle and the lever. The semicircular blocks match the grooves and can engage the handle when it is tangent to or perpendicular to the rotating frame, eliminating the need for additional handle fixing. This facilitates the rotation of the lever and its underlying components and reduces vibration transmission. Anti-rotation plates and anti-torsion plates are provided on the upper surface of the connecting frame, which can respectively enhance the lever's resistance to torque and torque, ensuring that the device maintains the adjustment effect of the bolts when the lever is used in different rotation methods and preventing the lever from bending.

[0010] According to the present invention, a lever arm fixture for adjusting bolts of a passive yaw caliper includes a semicircular block that engages with a groove. Six semicircular blocks are arranged in a 3:3 configuration on the inner wall of the rotating frame. These components enable the semicircular blocks to engage with the handle in conjunction with the groove. The arrangement of six semicircular blocks ensures a certain degree of fixation of the handle when it is tangential to or perpendicular to the lever.
