The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] like Figures 1 to 8 The shrink-fit stator device shown in the figure comprises a drive disc mechanism 1, a heating sleeve mechanism 2 and a discharge mechanism 3, as shown in FIG. Figure 1 As shown in the figure, the drive disk mechanism 1 includes a disk body 11 and a driving member 12. A plurality of positioning fixtures 13 are evenly arranged on the disk body 11 along the circumferential direction. The positioning fixture 13 includes a base 13a, a shell positioning seat 13b fixed on the base 13a, and a stator positioning cylinder 13c arranged side by side with the shell positioning seat 13b; it should be pointed out here that at least three positioning fixtures 13 are provided, in addition to the assembly station corresponding to the heating suit mechanism 2 and the unloading station corresponding to the unloading mechanism 3, a loading station is also included for placing the shell and the stator on the positioning fixture 13;

[0034] The heating sleeve mechanism 2 is arranged on the peripheral side of the driving disk mechanism 1, and includes a shell heating component 21 and a stator grabbing component 22 arranged side by side, and a driving component 23 for driving the two to move; the unloading mechanism 3 is arranged on the peripheral side of the driving disk mechanism 1, and is used to remove the shell with the stator sleeve from the disk body 11; wherein the spacing between the heating component and the stator grabbing component 22 is set corresponding to the spacing between the shell positioning seat 13b and the stator positioning cylinder 13c.

[0035] In the specific implementation, firstly, the material is loaded at the first positioning tool 13, and the loading here can be clamped by a robot or manually, that is, the stator is loaded into the stator positioning cylinder 13c, and the shell is placed on the shell positioning seat 13b; then the driving disk mechanism 1 drives the turntable to rotate to the heating set mechanism 2, the shell heating component 21 extends into the shell for heating, and the stator grabbing component 22 grabs the stator. After the heating is completed, the stator is placed in the shell to complete the assembly, and finally the disk body 11 rotates to the unloading mechanism 3, and the shell loaded with the stator is removed through the conventional clamping structure to complete the stator shrink sleeve operation.

[0036] In the above embodiment, a plurality of positioning fixtures 13 are arranged on the driving disk mechanism 1, and the positioning fixtures 13 include a shell positioning seat 13b and a stator positioning cylinder 13c. When the disk body 11 on the driving disk mechanism 1 is rotated to the heating sleeve mechanism 2, the shell heating component 21 heats the shell, and the stator grabbing component 22 grabs the stator and places it in the heated shell. Through the rotation of the disk body 11, the continuous operation of the stator shrink sleeve can be realized, and compared with the prior art, the efficiency of the stator shrink sleeve is improved.

[0037] Based on the above examples, please refer to Figure 2 Figure 3 and Figure 5 In order to facilitate maintenance and replacement of the positioning tool 13, the positioning tool 13 is detachably arranged in the embodiment of the utility model, and the base 13a has handles 13d at both ends, and the base 13a has at least two positioning columns 13e at the bottom, and the disk body 11 has positioning grooves corresponding to the positioning columns 13e, and the disk body 11 also has a clamping member 14 arranged corresponding to the side of the base 13a. The clamping member 14 here can be screwed with a stud to achieve compression of the base 13a, and the positioning columns 13e and the positioning grooves are arranged to facilitate accurate positioning of the base 13a, and the base 13a can be easily disassembled by the arrangement of the handles 13d.

[0038] Please refer to Figure 2 In the embodiment of the utility model, in order to detect whether a housing is loaded or whether an operation is performed at each positioning fixture 13, the disk body 11 is also provided with a laser detector arranged toward the positioning fixture 13. By emitting laser toward the housing positioning seat 13b or the stator positioning cylinder 13c, it is used to detect whether a stator or housing is loaded or whether a mechanism enters the housing or the stator positioning cylinder 13c for operation, thereby improving the reliability of the device operation.

[0039] Please refer to Figure 6 In some embodiments of the present invention, the stator grabbing member is an internal support type clamp, and the shell heating component 21 is a spiral columnar heating structure. When the disk 11 drives the positioning tool 13 to move to the position where the heating suit mechanism 2 is located, the shell heating component 21 corresponds to the shell, and the stator grabbing component 22 corresponds to the stator. Please continue to refer to Figure 1The driving assembly 23 includes a lifting drive 23a connected to the shell heating assembly 21 and the stator grabbing assembly 22 and a transverse drive 23b connected to the lifting drive 23a. The moving direction of the transverse drive 23b is parallel to the arrangement direction of the shell positioning seat 13b and the stator positioning cylinder 13c. By such a configuration, when the disk 11 rotates to the heating set mechanism 2, only the lifting drive 23a needs to be lowered, so that the shell heating assembly 21 extends into the shell for heating, and the stator grabbing piece extends into the inner side of the stator inner wall. After the shell is heated, the clamping claws on the stator grabbing piece expand outward to fix the stator. After the lifting drive 23a rises again, the transverse drive 23b moves toward the shell positioning seat 13b, so that the stator clamper clamps the stator and moves it to the upper part of the heated shell. The lifter descends again to install the stator into the shell. In the embodiment of the utility model, since the positioning tool 13 has both the stator and the shell positioning, the time for clamping the stator after heating is reduced, and the efficiency of the stator heat sleeve is further improved.

[0040] Please continue to refer to Figure 1 , Figure 2 and Figure 7 In the embodiment of the utility model, in order to further improve the reliability of the stator shrink sleeve, a stator detection mechanism 4 is also provided; in some embodiments of the utility model, four positioning fixtures 13 are provided, and the heating sleeve mechanism 2 is in the second position according to the rotation direction of the disk body 11, and the unloading mechanism 3 is in the fourth position. The stator detection mechanism 4 is arranged at the third position of the disk body 11, and the stator detection mechanism 4 corresponds to the shell positioning seat 13b, including an outer cylinder 41 that can be raised and lowered, and an inner cylinder 42 that is arranged in the outer cylinder 41 and can be raised and lowered relative to the outer cylinder 41, the outer cylinder 41 contacts the top of the shell, and the inner cylinder 42 contacts the top of the stator, and the inner cylinder 42 is also connected to a depth detector 43 for detecting the moving distance of the inner cylinder 42 relative to the outer cylinder 41. It should be pointed out here that the depth detector 43 can be a GT detection, such as Figure 8 As shown in , the inner cylinder 42 is provided with a vertical slotted hole, and the outer cylinder 41 has a screw that can move in the slotted hole. With this arrangement, at the beginning, the inner cylinder 42 is at the lowest position, and it first contacts the top of the stator. After the outer cylinder 41 continues to descend and contacts the shell, the distance moved by the outer cylinder 41 relative to the inner cylinder 42 can be known. This distance is the distance that the stator extends into the shell. If the distance is detected to be out of the set range, an alarm is issued. Please continue to refer to Figure 1 In order to further improve the assembly efficiency, in some embodiments of the present invention, a fan is further provided toward the stator detection mechanism 4 to dissipate heat from the housing. The fan can accelerate the cooling of the housing, thereby shortening the fixing time of the stator, thereby shortening the assembly cycle, and further improving the assembly efficiency.
