Description

Technical Field

[0001] The utility model relates to the field of motor assembly, in particular to a motor assembly device. Background Art

[0002] The motor is the core equipment of new energy. The existing motor assembly device generally includes a positioning structure for positioning the stator and upper and lower ejectors for positioning and moving the rotor. When the product needs to be assembled, the stator is first placed on the positioning structure and pressed tightly. Then the lower ejector rises and the rotor is placed on the lower ejector. The upper ejector descends to support the rotor, and the upper pressure head starts working to assemble the stator and rotor together.

[0003] The core of motor assembly lies in the coaxiality of the rotor and stator, which is mainly determined by the coaxiality of the upper and lower ejectors and the positioning structure, especially the coaxiality between the upper and lower ejectors. Because the upper and lower ejectors will move, it is difficult to ensure extremely high coaxiality. At the same time, the rotor mainly relies on the contact between the upper and lower ejectors at both ends of the shaft and the upper and lower ejectors for positioning. Once the upper and lower ejectors have a relatively small misalignment, it is easy to cause the rotor concentricity to shift, affecting the quality of motor assembly. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a motor assembly assembly device, which effectively improves the coaxiality of the rotor and the stator during assembly.

DETAILED DESCRIPTION

[0019] The utility model is further described below.

[0020] like Figure 1 and Figure 2As shown, the motor assembly assembly device disclosed in the present invention includes a base 1, a rotor positioning assembly and a stator positioning assembly, the rotor positioning assembly and the stator positioning assembly are both arranged on the base 1, the rotor positioning assembly includes a first alignment structure and a second alignment structure, the first alignment structure and the second alignment structure are arranged opposite to each other, the stator positioning assembly is located between the first alignment structure and the second alignment structure, the first alignment structure is movably matched with the base 1 in the direction away from and approaching the second alignment structure, the second alignment structure is fixedly connected to the base 1, and a space for positioning the rotor is formed between the first alignment structure and the second alignment structure.

[0021] When the motor assembly assembly device is used, the stator is assembled to the stator positioning assembly for positioning, one end of the rotor is aligned to the second alignment structure, and the other end is aligned to the first alignment structure. The rotor is positioned by the first alignment structure and the second alignment structure, thereby achieving assembly of the rotor and stator. In this application, the rotor is positioned by the first alignment structure and the second alignment structure, and the first alignment structure is movable, while the second alignment structure is fixed. Compared with the case where both alignment structures are movable, the coaxiality of the first alignment structure and the second alignment structure can be better ensured, effectively improving the coaxiality of the rotor and stator during assembly, and improving the assembly quality.

[0022] Since the second alignment structure is fixed and the first alignment structure is movable, the first alignment structure and the second alignment structure cannot move the rotor. Although assembly can be performed through positioning, the operation is very inconvenient. Therefore, in one embodiment of the present application, the stator positioning assembly is movably coordinated with the base 1 in the direction away from and approaching the second alignment structure. That is, in this embodiment, the stator can be moved by the stator positioning assembly to achieve the assembly of the rotor and the stator. Compared with the movable manner of the first alignment structure and the second alignment structure, although the two components are also movable in this embodiment, the contact area of ​​the stator that can be positioned is larger than that of the rotor, which makes it easier to ensure the accuracy of positioning, and the stator is less likely to be offset, thereby better ensuring coaxiality.

[0023] If both the first alignment structure and the second alignment structure are movable and the rotor is moved for assembly, it is better to arrange the first alignment structure and the second alignment structure up and down, because the first alignment structure and the second alignment structure are arranged up and down, which can make the center of gravity of the rotor located on the central axis, and the first alignment structure and the second alignment structure are precisely used to position the two ends of the rotor shaft, thereby reducing the possibility of offset. However, the first alignment structure is movable and the second alignment structure is fixed, which can itself ensure the accuracy of the rotor positioning, and more attention should be paid to the accuracy of the stator positioning. Therefore, in one embodiment of the present application, the movable directions of the first alignment structure and the stator positioning assembly are both horizontal. Because the stator is positioned by contact with its outer side, the vertical arrangement of the stator is not conducive to its accurate positioning. When the movable directions of the first alignment structure and the stator positioning assembly are both horizontal, the stator can be arranged horizontally, which can better position it and ensure its coaxiality with the rotor.

[0024] In one embodiment of the present application, the stator positioning assembly includes a positioning block 4 for positioning the stator, and the positioning block 4 is provided with a fixing structure for fixing the stator. The fixing structure can be fixed by clamping, pressing, etc., among which the quick clamp B7 is preferred, and the quick clamp B7 is more convenient to operate. Since the stator positioning assembly requires a certain height, a third support block 5 can be provided below the positioning block 4 for support. The positioning block 4 and the fixing structure can be connected by screws B9, and then connected with the positioning pin B8 and the screws B9, so that the stator can be quickly fixed.

[0025] To achieve accurate movement of the stator positioning assembly, in one embodiment of the present application, a second track B4 is provided on the base 1, and the positioning block 4 is slidably disposed on the second track B4. The positioning block 4 is connected to a second lead screw B5 for driving the positioning block 4 to slide along the second track B4, and the second lead screw B5 is connected to a second rotating wheel B6. The positioning block 4 is movably disposed on the second track B4 to improve its sliding accuracy. The use of the second lead screw B5 to drive the movement of the stator positioning assembly is a purely mechanical structure, and the assembly process can be stopped at any time to adjust the product's assembly state. The sliding structure has a minimal impact on the bearings, reducing the bearing damage rate. The reverse action also allows for non-destructive disassembly of the product.

[0026] To facilitate operation after the stator is accurately positioned and to facilitate stopping for adjustment at any time, in one embodiment of the present application, the second rotating wheel B6 is provided with a locking mechanism. This locking mechanism can be used to lock the second rotating wheel B6 at any time, thereby locking the position of the stator. The locking mechanism can adopt a bolt-tightening or quick-clamping structure.

[0027] Regarding the specific structure of the first alignment structure, in one embodiment of the present application, the first alignment structure includes a first support block 2 and a first ejector pin 3. The first ejector pin 3 is disposed on the first support block 2 and faces the second alignment structure. The first ejector pin 3 supports the end of the rotor to achieve rotor positioning.

[0028] In order to achieve the movement of the first alignment structure, in one embodiment of the present application, a first track B2 is provided on the base 1, and the first support block 2 is slidably provided on the first track B2. The first support block 2 is connected to a first screw B3 for driving the first support block 2 to slide along the first track B2, and the first screw B3 is connected to a first rotating wheel B1. By rotating the first rotating wheel B1, the first screw B3 can be used to drive the first support block 2 to move, thereby achieving the movement of the first alignment structure, so that it can cooperate with the second alignment structure to achieve the positioning of the rotor. Similarly, a locking mechanism is provided on the first rotating wheel B1, which can lock the first alignment structure at any time, thereby stabilizing the rotor.

[0029] As for the specific structure of the second alignment structure, in one embodiment of the present application, the second alignment structure includes a second support block 7 and a second ejector pin 6, and the second ejector pin 6 is arranged on the second support block 7 and is arranged toward the first alignment structure. The second ejector pin 6 supports the end of the rotor and cooperates with the first alignment structure to achieve the positioning of the rotor. The first ejector pin 3 and the second ejector pin 6 can be connected to the first support block 2 and the second support block 7 respectively through an interference fit, and then fixed with a stop pin B10, which can eliminate the tooling gap and prevent the ejector pin from falling off. The first support block 2 can be connected to the base plate through the locating pin B8 and the bolt, thereby achieving sliding cooperation with the track. The second support block 7 can be directly connected to the base 1 using the locating pin B8 and the bolt.
