Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] as attached Figure 1~4 As shown: the base 7 is provided with cross-shaped T-shaped slots 8, and each T-shaped slot 8 has a T-shaped bolt 5 locked by a nut 6, and the T-shaped bolt has a stepped shaft-shaped structure.

[0015] In order to facilitate positioning, the top surface of each T-bolt 5 has a stepped positioning surface.

[0016] After the lamination is completed, several iron chips positioned on the positioning mandrel 4 are compressed by the pressure plate 1; in order to make the iron chips connected as a whole to form the stator core assembly 2, it is necessary to carry out overlay welding in the welding groove 9, which It is unavoidable to make part of the core pieces and the positioning mandrel 4 or the pressing plate 1 be connected together by mistake welding;

[0017] During the separation operation, the stator core ass...

Abstract

The invention discloses a laminated stator iron core assembly welding stripping device, and belongs to welding tooling. The objective of the invention is to provide a welding stripping tooling which can adjust the positioning size. The laminated stator iron core assembly welding stripping device includes a base; cross T-shaped grooves (8) are formed in the base (7); T-shaped bolts (5) locked by nuts (6) are arranged in the T-shaped grooves (8); and the T-shaped bolts are of stepped shaft-shaped structures. The laminated stator iron core assembly welding stripping device can greatly reduce the number of stripping tooling, can reduce the cost, is easy to manage, and is a laminated stator iron core assembly welding stripping tooling.

Description

technical field [0001] The invention relates to a device for unloading welded parts, in particular to a device for unloading welded parts of a laminated stator core assembly, which belongs to welding tooling. Background technique [0002] As we all know, the stator core assemblies of small and medium-sized permanent magnet synchronous motors are generally formed by laminating and welding several body chips punched with four welding grooves on the outer edge. In order to form a number of inclined slots that can weaken the cogging effect in the inner hole of the stator core assembly, the stator core assembly is usually assembled by laminating a mold composed of a mandrel and a pressure plate; After the completion, the mold holding the stator core assembly is removed from the hydraulic press and sent to the welding station to weld and fix the iron chips. Since it is inevitable that part of the iron chips will be incorrectly welded and connected to the mold during the welding p...
