Motor stator core lamination forming device and method

Abstract

The invention discloses a motor stator core lamination forming device and method, and belongs to the field of motor stator manufacturing. The punching sheets, the upper tooth pressing plate and the lower tooth pressing plate are preliminarily positioned through the tooth groove plugging strips, the tooth groove plugging strips and tooth grooves are tightly wedged through the plugging strip lower wedge-caulking mechanism and the plugging strip upper wedge-caulking mechanism, the position precision of the tooth grooves in the punching sheets is guaranteed, and meanwhile the position precision of the tooth grooves in the punching sheets is guaranteed through the linkage effect of the tensioning centering mechanism. Wedge-caulking positioning, punching sheet inner wall tensioning centering and pressing pressure maintaining of punching sheet tooth grooves are sequentially completed in the downward pulling and moving process of the center pull rod, welding and fixing can be directly carried out on a lamination welding tool, the motor stator lamination assembly step and the multi-station circulation process are reduced, the motor stator lamination welding operation is more convenient, and the production efficiency is improved. And the manufacturing efficiency and the manufacturing precision are improved. Besides, the coaxiality of the motor stator iron core is detected by innovatively adopting a linear cutting principle, complicated detection tools and detection equipment are not needed, the detection operation is simple and efficient, and the detection is accurate and stable.

Description

technical field [0001] The invention relates to a motor stator lamination forming tool, more particularly, to a motor stator iron core lamination forming device and method. Background technique [0002] figure 1 and figure 2 It is a schematic structural diagram of an existing motor stator, which is stacked from bottom to top by the lower flange end plate A1, the lower tooth pressing plate A2, the punching piece A3, the upper tooth pressing plate A4 and the upper flange end plate A5. , The stator core is composed of hundreds of punching sheets A3 between the lower tooth pressing plate A2 and the upper tooth pressing plate A4, and is welded and fixed around the punching sheet A3 by welding ribs A6, and the upper and lower ends of the welding ribs A6 are respectively connected by positioning pins A7 is positioned with the flange end plate of the corresponding end, and there are corresponding tooth slots A8 on the lower flange end plate A1, the lower tooth pressing plate A2, ...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the shortcomings of the existing motor stator core lamination welding device, such as cumbersome lamination assembly operation, low production efficiency and poor precision, and provide a motor stator core lamination forming device and method, which adopts the technical solution of the present invention , use the alveolar plug for preliminary positioning of the punching plate and the upper and lower tooth pressure plates, which facilitates the rapid assembly of the motor stator core, and use the lower plug wedge mechanism and the plug upper wedging mechanism to wedge the tooth slot plug with the tooth slot to ensure The position accuracy of the tooth grooves on each punching sheet is ensured, and at the same time, the linkage action of the tensioning and centering mechanism is used to complete the wedge-tight positioning of the punching sheet's tooth grooves, the tensioning and centering of the inner wall of the punching sheet, and the motor stator in sequence during the pull-down movement of the center rod. The compression and pressure holding of the iron core can be directly welded and fixed on the lamination welding tool, which reduces the lamination assembly steps of the motor stator and the multi-station circulation process, makes the lamination welding operation of the motor stator more convenient, and improves the production of the motor stator. Efficiency, greatly improving the manufacturing accuracy of the motor stator, and improving the product qualification rate
