Description

Technical field:

[0001] The utility model belongs to the technical field of controller box production, and particularly relates to an assembly tool for a locking strip component. Background technology:

[0002] The locking bar assembly is a component of the controller case, and is mainly used to fix the functional module in the case slot. The locking bar assembly includes a locking bar and a plurality of wedges, and the locking bar and the plurality of wedges are assembled together by studs.

[0003] Existing locking strip assemblies are generally assembled manually. Because they involve the assembly of multiple wedge blocks, it is inevitable that there will be errors in the direction or angle of the wedge block assembly, resulting in the length of the locking strip assembly being inconsistent with the normal assembly length. Operators often fail to discover this in time, resulting in unqualified products. In addition, the front end wedge block is provided with an internal thread, and the front end of the stud is provided with an external thread. The stud and the front end wedge block form a thread pair. When there are debris on the inclined surface between the front end wedge block and the adjacent wedge block, the inclined surfaces between the wedge blocks will not fit together. When the thread is tightened, the assembly axis will deviate. The front end wedge block will deviate to one side as a whole, causing excessive contact pressure on one side, and eventually causing the entire thread to bite, resulting in unqualified products.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
