Detailed Description

Example 1:

as shown in fig. 1-5, a fan assembly fixture comprises a limiting block 1, a base 2 and a pressing block 3, wherein the limiting block 1 is located on the base 2 and used for positioning a motor 12, a placing groove 4 used for positioning a balancing weight 15 is formed in the base 2, the pressing block 3 is movably connected above the limiting block 1 through a support frame 5, the pressing block 3 is controlled by a power mechanism and used for pushing the motor 12 and the balancing weight 15 to be assembled, a positioning structure used for positioning a volute 13 is arranged at the upper end of the limiting block 1, the shape of the positioning structure is matched with that of the volute 13, and a placing opening 10 is formed in one side of the limiting block 1. During assembly, the balancing weight 15 is firstly placed in the placing groove 4, a device connected with the balancing weight 15, generally a connecting shaft, is arranged at the bottom of the motor 12, the motor 12 is embedded into a mounting hole 15-1 of the balancing weight 15 through the connecting shaft, a volute casing 13 is mounted above the motor 12, and at the moment, the volute casing 13 is pressed down through the pressing block 3, so that the motor 12 is pressed down and assembled with the balancing weight 15. The positioning structure corresponding to the volute 13 is arranged on the limiting block 1, after the pressing block 3 presses the volute 13 to a certain height, the positioning structure can limit the volute 13, the limited volute 13 cannot be pressed downwards continuously, and the motor 12 cannot move downwards continuously, and as the positions of the positioning structure, the heights of the motor 12 and the volute 13, and the assembly positions of the motor 12 and the balancing weight 15 are preset, as long as the volute 13 is limited and cannot be pressed downwards continuously, that is, the optimal assembly position is reached, the assembly accuracy of the motor 12 and the balancing weight 15 can be guaranteed. Because the pressing block 3 is installed above the tool, the motor 12 is placed in the placing groove 4 from the upper side of the tool, so that the placing groove 4 is relatively troublesome and inconvenient, the placing opening 10 is formed in one side of the limiting block 1, and the motor 12 is conveniently placed in the placing groove 4.

The limiting block 1 is composed of a limiting unit and is provided with a through inner cavity, the inner cavity forms an accommodating cavity 16, and the placing opening 10 extends from the upper end of the limiting unit to the lower end of the limiting unit. The limiting block 1 is formed by an integral limiting unit with an inner cavity in the middle, the integrity is strong, and the problem that assembly is unstable due to unstable connection of part of units in a plurality of limiting units cannot occur.

The width of the placing opening 10 is the same as the maximum outer diameter of the motor 12 body, so that the motor 12 is conveniently placed into the accommodating cavity 16 for assembly, the pressing block 3 is arranged above the tool, and the motor 12 is inconvenient to place from the upper side due to small space.

A notch 9 is formed in one side of the positioning structure, and the notch 9 is used for placing a tuyere of the volute 13. When the pressing block 3 presses the volute casing 13 down and further presses the motor 12 to move downwards, the volute casing 13 has a moving space on the positioning structure, and the volute casing 13 has a nozzle opening and also needs to have a corresponding moving space.

One end of the support frame 5 is connected with a support plate 6, the support plate 6 is located above the limiting block 1, the power mechanism is a hydraulic cylinder 7, and the hydraulic cylinder 7 is installed on the support plate 6.
