DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to specific embodiments and drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] It is understood that the above description is only exemplary and is not intended to limit the scope of the present application.

[0023] The drawings will be described below Figures 1-4 Some embodiments of the present application provide a cutting machine for machining stator and rotor laminations.

[0024] The present application comprises a die cutting machine 100, an indexing assembly 200 and a tooling assembly 300. The surface of the die cutting machine 100 is provided with an anvil 140, and the output end of the die cutting machine 100 is connected with a die cutting knife 130 which moves relative to the anvil 140, and the die cutting machine 100 is used to drive the die cutting knife 130 to reciprocate. The indexing assembly 200 is fixedly installed on the surface of the anvil 140, and the indexing assembly 200 comprises a toothed ring 210, a rotary table seat 220, and an outer rotor motor 230 and a drive cylinder 240 fixedly installed on the surface of the rotary table seat 220. The surface of the outer rotor motor 230 is provided with a tooth ring which is in transmission engagement with the inner side of the toothed ring 210, and the outer rotor motor 230 is used to drive the rotary table seat 220 to rotate inside the toothed ring 210. The tooling assembly 300 is fixedly installed on the surface of the rotary table seat 220, and the tooling assembly 300 comprises a rotary drum seat 310, a moving rod 320, and a sleeve pipe 330 which is slidably sleeved inside the rotary drum seat 310. The inner side of the rotary drum seat 310 is fixedly installed with an inner expansion sleeve 340 which is sleeved inside the sleeve pipe 330. The surface of the inner expansion sleeve 340 is provided with a plurality of expansion petals 341, and the output end of the drive cylinder 240 is connected with the end of the moving rod 320, which is used to drive the sleeve pipe 330 to slide up and down outside the inner expansion sleeve 340.

[0025] Specifically, in the embodiment, the punching machine 100 drives the punching cutter 130 to reciprocate relative to the anvil 140 through the linkage movement of the flywheel shaft 110 and the crank connecting rod 120 to realize the shearing operation on the stator and rotor punching sheet. The rotating table seat 220 is driven to rotate by the outer rotor motor 230 in the indexing assembly 200 relative to the fixed tooth ring 210 to ensure the accurate positioning of the stator and rotor punching sheet in the machining. Meanwhile, the tooling assembly 300 realizes the quick fixing and loosening operation through the cooperation of the expansion petals 341 of the inner expansion sleeve 340 and the inner hole of the punching sheet, thereby improving the machining efficiency.

[0026] On the basis of embodiment 1, the bottom end of the punching cutter 130 is provided with a cutting edge, and the cutting edge is in the form of a circular arc, and the center of the circular arc is coaxial with the shaft center of the indexing assembly 200 and the tooling assembly 300. Through the design of the circular arc cutting edge, the stress is more uniform during shearing, avoiding the bias cutting phenomenon that may be caused by the traditional straight blade design, and effectively improving the punching precision and machining consistency.

[0027] On the basis of embodiment 1, the inner side tooth ring of the fixed tooth ring 210 is in transmission engagement with the output end of the outer rotor motor 230. The accurate rotation of the rotating table seat 220 inside the fixed tooth ring 210 is realized through the driving of the outer rotor motor 230. Combined with the high responsiveness of the outer rotor motor, high-precision control of the indexing positioning during the machining of the stator and rotor punching sheet can be realized, ensuring that each punching is completed at the accurate position.

[0028] On the basis of embodiment 1, the inner expansion sleeve 340 is provided with a plurality of expansion petals 341 on the surface, and each expansion petal 341 is uniformly distributed in the circumferential direction. The outer periphery of the expansion petal 341 is in the form of an inverted conical surface, and a split gap is arranged between adjacent expansion petals 341. When the sleeve tube 330 moves upward, the expansion petals 341 are pushed to move radially inward, so that the outer diameter of the inner expansion sleeve 340 is reduced, thereby loosening the punching sheet. When the sleeve tube 330 moves downward, the expansion petals 341 are naturally expanded, and reliable cooperation with the inner hole of the stator and rotor punching sheet is formed, thereby completing the quick fixing. This design significantly improves the unloading and loading efficiency and is suitable for continuous production operation. Specifically, the expansion petals 341 on the surface of the inner expansion sleeve 340 are in the form of expansion in the natural state, which is convenient for abutting against the inner side of the axial groove of the stator and rotor punching sheet to fix the stator and rotor punching sheet. When the sleeve tube 330 moves upward, the expansion petals 341 are pushed radially inward, the diameter of the inner expansion sleeve 340 is reduced, and the sleeve tube 330 pushes the stator and rotor punching sheet to move upward for quick unloading. When the stator and rotor punching sheet is pressed downward, the sleeve tube 330 moves downward along the outer periphery of the expansion petals 341, and the expansion petals 341 are naturally expanded to fix the stator and rotor punching sheet.

[0029] As Figure 1As shown, the input end of the outer rotor motor 230 is electrically connected with a controller, and the output end of the controller is electrically connected with the input end of the punching machine 100. The controller coordinates the reciprocating motion of the punching machine 100 and the indexing rotation of the outer rotor motor 230, so as to ensure the automatic operation of the equipment. Through the preset program, the synchronization of the punching action and the indexing action is realized, the frequency of manual intervention is reduced, and the stability and safety of the equipment are further improved.

[0030] Through the above embodiment, the high-precision and high-efficiency processing of the stator and rotor punching sheet is effectively realized, and the positioning is accurate, the fixing is reliable, the discharging is convenient, the automation degree is high and the like. The above specific implementation manner is only a preferred embodiment of the utility model, and simple changes or replacements made by those skilled in the art on the basis of the spirit and technical scheme of the utility model should be considered as falling within the protection scope of the utility model.
