Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] refer to figure 1 and figure 2 , is a stator punching and slotting machine disclosed in the present invention, comprising a base 10, a frame 1 fixed on the base 10 and a stop frame 2, a motor 11 and a drive shaft driven by the motor 11 are arranged on the frame 1 12. The axial direction of the drive shaft 12 is along the vertical direction. The tray 3 is fixed on the drive shaft 12. The surface of the tray 3 is along the horizontal direction. The tray 3 is fan-shaped. The drive shaft 12 passes through the center of the tray 3. It is the blanking opening 31, and the size of the blanking opening 31 can pass through the punching sheet 6 in a horizontal state. Below the tray 3 is provided a discharge rack 4 for receiving punched sheets 6 .

[0040] The center of the tray 3 protrudes upwards and is fixed with a boss 32, and the side wall of the boss 32 ...

Abstract

The invention discloses a slot alignment machine for a stator punching sheet, relating to the technical field of the manufacturing of electric motors. The technical points thereof are that the slot alignment machine comprises a machine frame and a baffle frame, the machine frame is provided with a motor and a tray driven by the motor, the surface of the tray is provided with a feeding opening, andthe baffle frame stops a punching sheet from rotating with the tray to fall into the feeding opening when the tray is rotated. A friction ring is fixed on the tray, the baffle frame is provided witha cylinder and a working frame driven by the cylinder, a pressing wheel is rotatingly arranged on the working frame, the working frame can slide to allow the pressing wheel to press against an outer side wall of the punching sheet such that the punching sheet is clamped among the pressing wheel, the baffle frame and the friction ring. A discharge frame for taking the punching sheet is arranged under the tray. The slot alignment machine can perform slot alignment and stacking on the punching sheet instead of manpower, the labor is saved, the positioning of the punching sheet stacked by the slotalignment machine is accurate, a manufactured stator has good positioning performance and electromagnetic uniformity, and therefore, the operational stability of the motor is ensured.

Description

technical field [0001] The invention relates to the technical field of motor production, in particular to a stator punching and slotting machine. Background technique [0002] The motor includes a stator and a rotor. The stator is generally formed by stacking multiple stator punches with the same shape and specification. [0003] The existing authorized announcement number is the Chinese invention patent of CN100352134C, which discloses a motor stator, including a cylindrical stator core. figure 1 , the outer wall of the stator core is circular, and the outer wall of the stator core is uniformly provided with four positioning slots along the circumferential direction; the stator core can be formed by stacking the stator punches, and the positioning slots are used to facilitate positioning when the stator punches are stacked , so that the stacking angles of all stator punches are the same. [0004] At present, the slotting and stacking processes of stator punching are gener...
