Problems solved by technology

[0005] The purpose of the present invention is to provide a bolt tightening tool for tightening the gear bolts of the balance shaft, which solves the problem that the torque cannot reach the specified torque when the bolt is tightened, and at the same time avoids the excessive tooth shape parameters caused by the use of gears to lock the balance shaft system. Problems such as shear failure of the flat key due to excessive force

Embodiment Construction

[0016] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0017] Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides a bolt tightening tool, including a first base block 1, a second base block 2 and a connecting block 3, wherein the first base block 1 and the second base block 2 The first base block 1 , the second base block 2 and the connection block 3 are integrally formed in order to improve the overall strength and facilitate processing and forming through the connection of the connecting block 3 . The connection block 3 is an inclined plate structure. In order to improve the overall stability and distribute the force evenly, the inclination angle of the connection block 3 is 45°, and the height of the second base block 2 is higher than that of the first base block 2. Base block 1, the first base block 1 ...

Abstract

The invention discloses a bolt tightening tool which comprises a first base block, a second base block and a connecting block. The first base block and the second base block are connected through theconnecting block, the height of the second base block is larger than that of the first base block, and the first base block is provided with a supporting face. The outline of the supporting face is matched with the outline of a designated part of a cylinder body, a locking claw is arranged at the side end of the second base block in a protruding mode, and the free end of the locking claw extends into a rotating path of a rear balance block of the cylinder body. Compared with the prior art, the problem that the torque cannot reach the specified torque when a bolt is tightened is solved, and meanwhile the problems that the tooth profile parameter exceeds the standard when a gear is used for locking a balance shaft system, and a flat key is sheared and damaged due to overlarge stress are solved.

Description

technical field [0001] The invention relates to the technical field of processing tooling, in particular to a bolt tightening tooling. Background technique [0002] For the tightening of the bolts in the axial direction of the rotating system, it is necessary to lock a certain part of the rotating system to prevent the entire system from rotating with the tightening wrench during the bolt tightening process, resulting in the failure of the bolts to be tightened to the specified torque. [0003] However, some parts in the rotating system cannot be used as locking parts, such as gears with small anti-destructive torque, parts positioned by keys, etc. If they are used as locking parts, it is easier to cause damage to these parts when tightening the bolts. Damage to components or damage to positioning positions. [0004] Therefore, when the bolts of this type of rotating system are tightened, tooling must be used to lock the relevant parts that are not easily damaged, so as to ...
