Description

A torque wrench extension arm assembly

technical field

The utility model relates to the technical field of mechanical maintenance equipment, in particular to a torque wrench extension arm assembly.

Background technique

In the torque check of 900N·m, the torque required by the process is relatively large, requiring multiple people to work at the same time, and the arm of the torque wrench is short, which cannot meet the operation requirements. In addition, because the center pin to be checked is intricate on the horizontal plane, the existing in-line extension arm has a narrow working space, which is inconvenient for operation, and the existing sleeve-type extension arm is directly placed on the torque wrench. At the same time, it will cause damage to the adjustment handle of the torque, resulting in loss of the original process level, making the torque inaccurate, and unable to meet the process requirements. The torque wrench for checking the center pin is generally relatively heavy, and it will be inflexible and convenient even if multiple people work at the same time after installing the extension arm.

Therefore, to develop a torque wrench that will not cause damage to the torque during use, has good flexibility, large working space and is easy to operate has become a problem that people in the industry need to solve urgently.

A torque wrench extension arm assembly, including an L-shaped extension arm assembly, the left and right sides of the L-shaped extension arm assembly are respectively sleeved with a replaceable extension arm and a connecting rod, wherein a torque wrench is sleeved at one end of the connecting rod The L-shaped extended arm assembly includes a female connection buckle and a sub-connection buckle that matches the female connection buckle, wherein the left side of the female connection buckle is fixedly provided with the replaceable extension arm For the matching sleeve, the upper and lower ends of the sub-connection buckle are respectively connected to the female connection buckle through hexagon socket bolts and lug plates.

Further, the other end of the connecting rod is provided with a handle.

Further, the connection between the connecting rod and the torque wrench and between the connecting rod and the handle are fastened by screws.

Beneficial effects of the utility model: through the function of the L-shaped extended arm assembly, the replaceable extended arm and the connecting rod, the flexibility of the torque wrench is effectively improved, and the torque will not be damaged, the working space is large and the operation is convenient. The extended arm assembly of the torque wrench has a broader development space.
