Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, fig. 2, and fig. 3, this synchronous machine controller and motor casing's connection structure, including motor body 1 and controller 2, controller 2 is fixed in motor body 1's outside, motor body 1's surface welded is fixed with four reference columns 3, reference column 3 is the cuboid structure, four reference columns 3 are two liang a pair, every is to offering the locating hole 4 that is located the same axis on reference column 3, locating hole 4 is located the middle part of reference column 3 and offers along the motor shaft place axial, controller 2's bottom surface is offered and is corresponded and can supply the cell body 5 that reference column 3 stretched into with every reference column 3 position, controller 2's inside is provided with four locating pins 6 that can lateral shifting, four locating pins 6 are two liang a pair and the position cooperatees with locating hole 4.

The principle of the structure is as follows: during assembly, the bottom surface of the controller 2 is arranged above the motor body 1 through the groove body 5 opposite to the positioning column 3, after the positioning column 3 is installed in place, the positioning hole 4 is positioned just opposite to the end part of the positioning pin 6, and the positioning pin 6 is moved to be inserted into the positioning hole 4, so that the controller 2 and the motor body 1 are fixed with each other.

Wherein, the activity mode of this locating pin 6 does: in the structure, when the rotating gear 7 rotates in the forward direction, the two adjusting gears 10 move towards the center of the space where the rotating gear 7 is located through meshing transmission, and similarly, when the rotating gear 7 rotates in the reverse direction, the adjusting gears 10 move towards the upper side and the lower side of the space where the rotating gear 7 is located.

The centers of the two adjusting gears 10 are fixed with a push rod 11 through the adjusting rod 9, the push rod 11 abuts against the end part of the positioning pin 6, that is, the moving track of the push rod 11 is the same as that of the adjusting gear 10, so that when the push rod 11 moves towards the center, the corresponding positioning pin 6 is pushed to move outwards until extending into the positioning hole 4, and it needs to be noted that a damping structure is arranged between the rotating gear 7 and the controller 2 in order to prevent the rotating gear 7 from passively and reversely running.

The end part of the positioning pin 6 is provided with a cambered surface structure 12 matched with the pushing rod 11, so that the matching effect between the positioning pin and the pushing rod is better.

When later controller 2 needs to be dismantled, in order to make locating pin 6 withdraw from locating hole 4, be provided with between locating pin 6 and the controller 2 and be in compression state spring 13, this spring 13 is located the upper and lower both sides of locating pin 6, and locating pin 6 is inside and the reference column 3 separation will be returned to the portable meeting of adjusting gear 10 upper and lower both sides through the elasticity of spring 13 promptly, and controller 2 can easily take off.
