[0028] At present, there are many types of motor casings and drive motor casings, and they are all heavy. The heating process needs to be completed separately on independent equipment, and then manually transported to the next process. Manual positioning is used to complete the equipment press-fitting with the stator. The whole process is cumbersome, requires a lot of equipment, occupies a large area and has a low degree of automation, resulting in low production efficiency. To solve the above problems, the present invention provides a casing hot sleeve and stator press-fitting mechanism.

[0029] As Figures 1 to 3 shown, the casing hot sleeve and stator press-fitting mechanism proposed by the present invention includes a base structure, a heating mechanism 400, a pressing mechanism 300, and a transfer robot (not shown in the figure) provided on the base structure. The heating mechanism 400 and the pressing mechanism 300 are arranged on the same base structure. The heating mechanism 400 can automatically heat the motor casing, and the pressing mechanism 300 can automatically press-fit the stator into the casing 10, realizing the integration of the heating mechanism 400 and the pressing mechanism 300. Moreover, during the heating and press-fitting processes, the transfer robot can transfer the casing 10 and the stator, which can greatly improve the degree of automation of the assembly of the casing 10 and the stator and greatly improve the production efficiency.

[0030] Specifically, the above base structure may include a frame 100 and a workbench 200 provided at the top of the frame 100. The workbench 200 is provided with a heating station, a cooling station, and a press-fitting station. Among them, the frame 100 can provide support and a setting foundation for the entire mechanism, and by setting the workbench 200, it is convenient to install the heating mechanism 400 and the pressing mechanism 300, facilitate heating the casing 10 at the heating station, cooling the casing 10 at the cooling station, and performing press-fitting operations on the casing 10 at the press-fitting station. In addition, the corresponding control mechanisms of the heating mechanism 400 and the pressing mechanism 300 can be arranged on the frame 100.

[0031] Moreover, the above heating mechanism 400 may include a heating support provided at the heating station of the workbench 200, an intermediate frequency induction heating sleeve (not shown in the figure) provided on the heating support, and a heating power supply (not shown in the figure) provided on the frame 100 or the workbench 200. The heating power supply is electrically connected to the intermediate frequency induction heating sleeve. By providing the heating support at the heating station of the workbench 200, the casing 10 can be placed and positioned; and by providing the intermediate frequency induction heating sleeve on the heating support, the casing 10 can be sleeved outside the intermediate frequency induction heating sleeve to perform intermediate frequency induction heating on the inner wall of the casing, and the heating power supply can provide electrical energy for the intermediate frequency induction heating sleeve. In addition, according to needs, multiple heating mechanisms 400 can be arranged on the workbench 200 to heat multiple casings 10 simultaneously; or only one heating mechanism 400 can be arranged on the workbench 200 to heat only one casing 10.

[0032] Moreover, in some embodiments, the above-mentioned heating support may include a heating rack 410 protruding from the workbench 200, a heating tooling plate 420 detachably disposed on the top of the heating rack 410, a heating positioning ring protruding from the heating tooling plate 420, and a locking structure disposed on the heating tooling plate 420. The above-mentioned intermediate frequency induction heating sleeve is disposed at the center of the heating positioning ring. The entire heating mechanism 400 can be supported by the heating rack 410 to form a certain distance from the workbench 200, which is convenient for heat insulation between the workbench 200 and the heating mechanism 400, and also convenient for arranging other structures under the heating rack 410. And through the heating tooling plate 420 disposed on the top of the heating rack 410, it is convenient to support the casing 10 and other structures. Moreover, through the heating positioning ring disposed on the heating tooling plate 420, the casing 10 placed on the heating tooling plate 420 can be positioned; and through the locking structure disposed on the heating tooling plate 420, the casing 10 placed on the heating tooling plate 420 can be further fixed to prevent the casing 10 from moving on the heating support, making the heating of the casing 10 stable and reliable. Moreover, the casing 10 can be moved to the heating tooling plate 420 by a transfer robot and positioned corresponding to the heating positioning ring; after the heating of the casing 10 is completed, the casing can be moved from the heating tooling plate 420 to another position (such as a cooling station) by the transfer robot.

[0033] Moreover, further, the above-mentioned locking structure may include elastic latches respectively rotatably disposed on opposite sides of the heating tooling plate 420. By respectively disposing an elastic latch on both sides of the heating tooling plate 420, the casing 10 placed on the heating tooling plate 420 can be locked and fixed from both sides, which is convenient for heating the casing 10 by the intermediate frequency induction heating sleeve. In addition, the above-mentioned intermediate frequency induction heating sleeve can be arranged to be liftable, that is, after the casing 10 is locked and fixed by the locking structure, the intermediate frequency induction heating sleeve can be extended into the middle hole of the casing 10, and then the heating of the casing 10 can be started.

[0034] Moreover, the above-mentioned heating rack 410 may include a plurality of support rods 412 protruding from the workbench 200, and a support platform 414 disposed on the tops of the plurality of support rods 412, and the above-mentioned heating tooling plate 420 may be disposed on the support platform 414.

[0035] In addition, a heat insulation plate can be arranged on the heating tooling plate 420 to isolate the machine shell 10, which can further prevent heat from being transferred to the workbench 200. In addition, corresponding to different types of machine shells 10, different types of heating tooling plates 420, heating positioning rings and locking structures can be set.

In addition, according to needs, a plurality of cooling mechanisms 500 can be arranged on the workbench 200 to cool a plurality of machine shells 10 simultaneously; or only one cooling mechanism 500 can be arranged on the workbench 200 to cool only one machine shell 10.
