[0131] The structure of the expanding and collecting mechanism 23 is the same as that of the clamping mechanism 3, except that the expanding and collecting mechanism 23 is arranged downwardly below the mounting frame 27, while the clamping mechanism 3 is arranged upwardly on the support platform 2;

[0132] In addition, what is fixed to the tooth plate 305 in the expansion mechanism 23 is not the vertical piece 302 but a pressing piece for compacting the stator punching sheets.

[0133] The expansion mechanism 23 can be used to adjust the circumferential distribution diameter of multiple pressing parts on the circumference to adapt to stator punching sheets of different diameter specifications and sizes. The output shaft is driven downward by the first-stage lifting device 21 to drive the installation frame 27 to move downward, and finally drive the expansion mechanism 23 to move downward.

[0135] A circular hole is provided in the center of the mounting plate 24 for the expansion and contraction mechanism 23 to pass through, and a plurality of shaping devices 25 are installed equidistantly along the circumference of the circular hole on the upper portion of the mounting plate 24. The welding mechanism is arranged at the lower portion of the mounting plate 24, and a plurality of welding devices are installed equidistantly along the circumference of the circular hole.

[0136] During the compaction of the stator punching sheets, the secondary lifting device 28 drives the mounting plate 24 to follow and move downward. At this time, the shaping device 25 thereon is used to shape the stator punching sheets from the outer edges of the stator punching sheets, thereby further improving the overlap of the stator punching sheets.

[0137] After the stator punching is compacted, the welding device 26 at the lower part of the mounting plate 24 is used to perform equidistant pulse welding on the stator punching from the outer edge along the circumference.

[0138] As a further solution of the present invention, please refer to Fig.12 The shaping device 25 includes a shaping cylinder fixedly mounted on the mounting plate 24 and pointing to the center of the circular hole, a shaping piston rod is arranged at the output end of the shaping cylinder, and a guide wheel is rotatably mounted at the end of the shaping piston rod.

[0139] During the compaction of the stator punching sheets, multiple forming cylinders are used to drive multiple forming piston rods to extend, so that the guide wheels at the ends of each forming piston rod roll and fit the outer wall of the stator punching sheet, thereby positioning the pressed stator punching sheet from the periphery and keeping the peripheries of each stator punching sheet highly overlapped.

[0140] As a further solution of the present invention, please refer to Fig.13 The welding mechanism includes a welding device 26. Specifically, the welding device 26 includes a push rod rotatably installed under the mounting plate 24, a push block connected to the push rod and slidingly matched with the lower surface of the mounting plate 24, and a pulse welding gun 29 installed under the push block and pointing to the center of the circular hole; wherein one end of the push rod is connected to a push motor installed on the mounting member 24.

[0141] As an example, the push rod can be a screw rod, and the push block is threaded with the push rod. The push motor drives the push rod to rotate, which can drive the push block to slide on the lower surface of the mounting part 24, thereby driving the pulse welding gun 29 to continuously approach the circular hole, thereby continuously approaching the edge of the stator punching sheet to perform pulse welding on it.

[0142] It should be noted that the transposition assembly, the material taking mechanism, the transfer structure, and the pressing mechanism are all provided with a travel switch, and the travel switch communicates with the PLC controller;

[0143] Specifically, the first power source 4, the motor 304, the lifting cylinder 10, the first motor 7, the second motor 9, the restraining motor 12, the second power source 15, the transfer cylinder 19, the first lifting device 21, the second lifting device 28, the shaping cylinder, and the push motor all communicate with the PLC controller. The first power source 4, the motor 304, the lifting cylinder 10, the first motor 7, the second motor 9, the restraining motor 12, the second power source 15, the transfer cylinder 19, the first lifting device 21, the second lifting device 28, the shaping cylinder, and the push motor and the PLC controller form an intelligent system. The pulse signal of a single motor or cylinder is superimposed with the pulse signal of the PLC controller to form an information element ant colony; the ant colony is an intelligent system that generates self-organization through a single pheromone; the intelligent control of multiple self-organizing systems is used to realize the displacement of the mechanical part. Through the above method, two functional multi-stator punching sheets can be memorized, the tooling automatic generation system can be realized, and the end can perform processing autonomously.

[0144] The purpose of this setting is to solidify complex skills into the machine, weaken the role of senior technicians, and allow ordinary people to use it to solve the problem of difficulty in hiring workers.

[0145] The switching time between different types of tooling has been changed from 50 minutes to 3 minutes, improving the current situation where the more models are switched, the lower the production capacity.

[0146] The above embodiments are exemplary rather than restrictive, so the technical solutions of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention are all included in the present invention.
