Embodiment Construction
[0029] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.
[0030] Such as Figure 4 , Figure 5 As shown, a casing interference self-locking nut installation tool according to the present invention includes a nut installation block 1, and the nut installation block 1 is a cuboid structure, and one end of the cuboid is provided with a through hole 101, and the other end is provided with a The boss 102 that plays a supporting role is provided with a notch on the through hole 101 . By setting the notch, the through hole 101 forms a superior arc groove on the nut mounting block 1, that is, the opening on the through hole 101 is smaller than its own widest point. By setting this closing structure, the nut mounting block can be effectively installed in the assembly process. 1 Pop out the through hole 101. The height dimension of the boss 102 is determined according to the thickness of the mou...

The invention discloses an installing tool and method for a casing interference self-lock nut. The tool comprises a nut installing block of a cuboid structure. A through hole is formed in one end of the cuboid, a boss playing a supporting role is arranged at the other end of the cuboid, and a notch is formed in the through hole. According to the installing scheme method, a force application cylinder shell is placed on a platform, and the to-be-installed self-lock nut is arranged in the through hole of the nut installing block; and the nut installing block is arranged in a hole where the self-lock nut needs to be installed, the top of the nut installing block is knocked through a bakelite hammer, the self-lock nut is arranged in the hole, assembling is finished, and the nut installing block is taken out. The installing tool and method can be suitable for narrow-space assembling of interference nuts with the requirement for perpendicularity. By the adoption of the device, self-lock nut assembling can be accurately and rapidly achieved, it is guaranteed that the center of the self-lock nut is perpendicular to the face of the installing edge, it is guaranteed that in the assembling process, an inner cavity is narrow and assembling is not convenient, and perpendicularity of the self-lock nut is ensured.
Description
technical field [0001] The invention belongs to the technical field of mechanical assembly, and in particular relates to a casing interference self-locking nut installation tool and an installation method thereof, and is particularly suitable for the assembly of parts requiring verticality between the self-locking nut and the end surface of the installation side. Background technique [0002] Such as figure 1 , figure 2 As shown, when a certain type of engine casing is assembled, the requirements for assembling self-locking nuts are: the thickness of the mounting side is 3mm, and 68 holes of φ9 are evenly distributed, and interference assembly is required such as image 3 The self-locking nut shown requires an interference of 0.064 to 0.2, and the self-locking nut has a verticality requirement of 0.3 / 50 on the mounting edge, so as to prevent the self-locking nut from being crookedly installed, resulting in failure to meet the assembly requirements of the casing in the late...
