Embodiment 2
[0049] A method for tightening an angle joint, using the above-mentioned tightening tool for the angle joint, comprising the following steps:
[0050]S1. Pre-installation, glue the angle joint on the installation end drawing, and screw the joint into the corresponding hole of the engine or parts for two to three teeth by hand;
[0051] S2. Connect the wrench with the tightening tool, place the first baffle 2 and the second baffle 3 of the tightening tool on both sides of the corner of the angle joint, and then insert the connecting end of the torque wrench or the constant torque wrench into the lower end of the sleeve 1 in the socket hole 11;
[0052] S3. Tighten the tooling to engage with the angle joint, hold the sleeve 1 with one hand and turn the torque wrench with the other hand, the first installation surface 21 and the second installation surface 31 respectively abut against both sides of the angle joint corner, and occlude the angle joint;
[0053] S4. Turn the angle ...

The invention discloses a tightening tool and a tightening method for an angle connector, and relates to the technical field of engine assembly. The tightening tool comprises a sleeve, a first baffleand a second baffle which are all made of iron, wherein the first baffle and the second baffle are fixedly arranged on the upper end surface of the sleeve and are arranged on the two sides of any longitudinal section of the sleeve respectively; the inner side surface of the first baffle is a first mounting surface; the inner side surface of the second baffle is a second mounting surface; the firstmounting surface is parallel to the second mounting surface; and a sleeving hole is formed in the lower end of the sleeve. The tightening tool provided by the invention can solve the problems that the tightening tool is insufficient in reliability and low in construction efficiency, and meanwhile, the problem that the construction requirement on the space is high is solved.
Description
technical field [0001] The invention relates to the technical field of engine assembly and testing, in particular to a tightening tool and a tightening method for an angle joint. Background technique [0002] In the process of engine assembly, it is necessary to organically combine the required parts and components and meet certain technological conditions. Among them, the joint parts are more important parts on the engine, such as the air compressor inlet joint, the air outlet joint, the steering pump joint and the air discharge joint, etc., which play the role of transitional connection of various pipelines. The angle joint is one of many joints, and its structure is a corner joint. This type of parts generally has a special installation angle requirement. Because of the special structure of this type of angle joint, it is impossible to directly select a sleeve of appropriate specification for tightening and loading and unloading like a normal straight line joint, and it ...
