Problems solved by technology

When installing and tightening parts such as pulleys, the bolts cannot be tightened because the crankshaft is rotatable
Existing assembly tools require two people to operate to complete the bolt tightening operation. The manual labor intensity is high, time-consuming, production efficiency is low, and the operation is complicated. It is difficult to meet the production needs. At the same time, the current tooling cannot be used in the assembly of different types of engines.

Embodiment Construction

[0018] Such as Figure 1~3 As shown, a universal fixed crankshaft tool includes a connecting plate 1 and a handle 5. In this embodiment, the handle 5 is approximately in the shape of a "7". One end of the connecting plate 1 is detachably fixed with a crankshaft positioning block 4. In this embodiment, a fixing hole is provided on the right part of the connecting plate 1, and then the lower end of the screw rod 4-1 is combined with the crankshaft for positioning. Block 4, and detachably fixed by nuts. The crankshaft positioning block 4 matches the end hole of the crankshaft, and the crankshaft positioning block 4 can be replaced for crankshafts of different types; There is also a flywheel positioning pin hole 1-2 between 4 and the expansion plate chute 1-1; it also includes an expansion plate 3 and a flywheel shell pin 7; the expansion plate 3 is inserted into the expansion plate chute 1-1 The other end is rotatably connected to the lower part of the handle 5 through the rota...

Abstract

The invention discloses a universal fixing crankshaft tool which comprises a connecting plate and a handle. A crankshaft locating block is detachably fixed to one end of the connecting plate. A telescopic plate sliding groove is formed in the other end of the connecting plate. A flywheel locating pin hole is further formed between the crankshaft locating block and the telescopic plate sliding groove. The universal fixing crankshaft tool further comprises a telescopic plate and a flywheel shell plug. The telescopic plate is inserted into the telescopic plate sliding groove to be distributed. The other end of the telescopic plate is connected with the lower portion of the handle through a rotating shaft in a rotating manner. A plug fixing groove is further formed in the lower portion of thehandle. The flywheel shell plug is distributed in the plug fixing groove in a sliding manner. A spring is further distributed on the upper portion of the plug fixing groove. The spring is distributedabove the flywheel shell plug. The universal fixing crankshaft tool is adopted for tightening a crankshaft, and has the advantages of being high in universality, easy to operate and good in fixing effect.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to a universal crankshaft fixing tool. Background technique [0002] In the engine manufacturing industry, production efficiency is always the most important link. Crankshaft assembly operations such as tightening pulleys are an important process in the engine production process. When installing and tightening parts such as pulleys, the bolts cannot be tightened because the crankshaft is rotatable. Existing assembly tools require two people to operate to complete the bolt tightening operation. The manual labor intensity is high, time-consuming, production efficiency is low, and the operation is complicated. It is difficult to meet the production needs. At the same time, the current tooling cannot be used in the assembly of different types of engines. . [0003] The disclosure of the above background technical content is only used to assist in understanding the concept and...
