[0025] At present, in the process of assembling large motors, the assembly of the aluminum shell and the stator is completed in a single machine in an offline manner, which requires manual multiple handling of the aluminum shell and the stator, long loading time and low production capacity. Secondly, the aluminum shell and the stator are not completely cooled after assembly, and there is still a gap between the aluminum shell and the stator. During the handling process, the aluminum shell and the stator are prone to displacement, which affects the use performance of the product. In addition, during the assembly process, the manual use of the power arm assembly has no torque and position parameter reference, and relies on manual experience operation, which can easily cause motor damage and improper motor assembly during the assembly process.

[0026] To solve the problems of long feeding time, low production capacity, displacement of the aluminum shell and the stator, motor damage and misassembly in the prior art, the utility model exemplary embodiments provide a motor aluminum shell and stator online hot-joint assembly system and equipment.

[0027] A motor aluminum shell and stator online hot-joint assembly system according to the utility model embodiments will be described in detail below with reference to the drawings.

[0028] Figure 1 The motor aluminum shell and stator online hot-joint assembly system according to the utility model embodiments is shown in the structure schematic diagram as Figure 1 The motor aluminum shell and stator online hot-joint assembly system includes a first conveying device 1, a stator feeding carrier 2, a second conveying device 4, a carrier positioning assembly 3, a driving device 7, a rack 8 and a multi-degree-of-freedom driving mechanism 5. The stator feeding carrier 2 is arranged at the driving end of the first conveying device 1 and is used for limiting the stator. The carrier positioning assembly 3 is arranged at the driving end of the second conveying device 4 and is used for positioning the motor aluminum shell. The driving device 7 is arranged on the rack 8 and is used for driving the first conveying device 1 and the second conveying device 4. The multi-degree-of-freedom driving mechanism 5 is arranged on the rack 8 and is used for clamping the motor aluminum shell and the stator of the stator feeding carrier 2 of the carrier positioning assembly 3 to complete the hot-joint online assembly.

[0029] In practical application, as Figure 1As shown, the motor aluminum shell and the stator are assembled in the online hot sleeve assembly system, the stator loading carrier 2 is arranged at the driving end of the first conveying device 1, the stator loading carrier 2 is used for limiting the stator, the carrier positioning assembly 3 is arranged at the driving end of the second conveying device 4, the carrier positioning assembly 3 is used for positioning the motor aluminum shell, the driving device 7 is arranged on the rack 8, the driving device 7 is used for driving the first conveying device 1 and the second conveying device 4, the multi-degree-of-freedom driving mechanism 5 is arranged on the rack 8, and the multi-degree-of-freedom driving mechanism 5 is used for clamping the motor aluminum shell of the carrier positioning assembly 3 and the stator of the stator loading carrier 2 to complete the hot sleeve online assembly. Based on this, the motor aluminum shell is manually carried to the carrier positioning assembly 3, and the stator is carried to the stator loading carrier 2. Only one manual carrying is needed to complete the hot sleeve online assembly of the motor aluminum shell of the carrier positioning assembly 3 and the stator of the stator loading carrier 2, thereby solving the problem of repeated manual loading and unloading and improving the production capacity. On this basis, when the multi-degree-of-freedom driving mechanism 5 clamps the motor aluminum shell of the carrier positioning assembly 3 and the stator of the stator loading carrier 2 to complete the hot sleeve online assembly, the stator loading carrier 2 limits the stator, thereby ensuring the relative position difference of the aluminum shell and the stator in the hot sleeve assembly process, effectively solving the problems of high noise and high vibration of the motor in the subsequent process test due to the displacement of the aluminum shell and the stator. In addition, the multi-degree-of-freedom driving mechanism 5 clamps the motor aluminum shell of the carrier positioning assembly 3 and the stator of the stator loading carrier 2 to complete the hot sleeve online assembly. Since the clamping and pressing of the multi-degree-of-freedom driving mechanism 5 can maintain constant arm force, the problem of incomplete assembly caused by uneven arm force distribution in the manual assembly process is effectively solved.

Since the sliding piece and the sliding groove can provide clear direction guidance for the movement of the object, the accuracy and stability of the movement are ensured. At the same time, the sliding device 6 is in the form of cooperation of the sliding piece and the sliding groove, because the sliding piece in the form of sliding rail and sliding groove can bear a larger weight and load. In the above-mentioned motor aluminum shell and stator online hot sleeve assembly system, the sliding device 6 in the form of sliding rail and sliding groove can ensure the stability and safety of the sliding device 6 in the running process.

[0031] As shown in the example, the direction of the sliding device 6 is the first direction of the multi-degree-of-freedom driving mechanism 5. It should be understood that the above-mentioned first direction is perpendicular to the first conveying device 1.

[0032] As shown in the example, Figure 2 The schematic diagram of the multi-degree-of-freedom driving mechanism applied according to the embodiment of the utility model is shown in the figure, Figure 2As shown, the multi-degree-of-freedom driving mechanism is further provided with a lifting device, the lifting device comprises a lifting frame 51, a transmission member 53 and a receiving cavity 52, the lifting frame 51 is arranged on the sliding member, one end of the transmission member 53 extends into the lifting frame 51 and is connected with the multi-degree-of-freedom driving mechanism, the other end of the transmission member 53 extends out of the lifting frame 51 and is connected with the receiving cavity 52, it should be understood that the lifting frame 51 and the receiving cavity 52 are both arranged vertically on the sliding member, the transmission member 53 extends into the lifting frame 51, and the other end of the transmission member 53 moves in the receiving cavity 52 to drive the multi-degree-of-freedom driving mechanism to move.

[0033] For example, the lifting device is a helical gear and rack transmission lifting device, the multi-degree-of-freedom driving mechanism needs to bear a certain load when the motor aluminum shell and the stator of the clamping carrier positioning assembly are assembled on the stator of the feeding carrier, and the transmission efficiency of the multi-degree-of-freedom driving mechanism has certain requirements, therefore, the helical gear and rack transmission has high transmission efficiency and large carrying capacity, and can meet the requirements of the multi-degree-of-freedom driving mechanism when the motor aluminum shell and the stator of the clamping carrier positioning assembly are assembled on the stator of the feeding carrier.

[0034] For example, the lifting direction of the lifting device is the second direction of the multi-degree-of-freedom driving mechanism, and it should be understood that the second direction is perpendicular to the second conveying device.

[0035] For example, the end of the multi-degree-of-freedom driving mechanism is further provided with a clamping mechanism, and the clamping mechanism is used for clamping the motor aluminum shell of the clamping carrier positioning assembly.

[0036] For example, the end of the multi-degree-of-freedom driving mechanism is further provided with a pressure sensor, and the pressure sensor is used for detecting the pressure value in the process of hot fitting online assembly of the motor aluminum shell and the stator of the feeding carrier.

[0037] Another aspect of the utility model further provides a motor aluminum shell and stator online hot fitting assembly equipment, including above-mentioned motor aluminum shell and stator online hot fitting assembly system.
