Problems solved by technology

Due to the structure of the self-locking stator core, the punches are interlocked to form a whole. In the prior art, when chamfering the self-locking stator core, it is necessary to press both ends of the self-locking stator core with a hydraulic press. In order to improve the overall stability, it is then transferred to the lathe to chamfer the outer circles at both ends, which has the disadvantages of inconvenient processing, low efficiency and high production cost

Embodiment Construction

[0017] See attached figure 1 , The self-locking stator core special chamfering device disclosed in the present invention includes a press-fit mechanism for press-fitting both ends of the stator core 1, a chamfering knife assembly 3, and a driving chamfering knife assembly 3 close to or away from the stator iron The displacement driving mechanism 4 at the outer circle of one end of the core 1 and the rotation driving mechanism 5 driving the chamfering knife assembly 3 to rotate around the outer circle of one end of the stator core 1 to chamfer the outer circle of the stator core 1. By adopting the above technical solution, when the stator core 1 is chamfered, the stator core 1 is first press-fitted by the press-fitting mechanism 2, and then the chamfering knife assembly 3 is driven close to one end of the stator core 1 by the displacement driving mechanism 4 The outer circle position, and finally the chamfering knife assembly 3 is driven to rotate around the outer circle of one e...

Abstract

The invention relates to a self-buckled special chamfering device for a stator core, which comprises a pressing mechanism for pressing both ends of the stator core, a chamfering cutter component, a displacement driving mechanism for driving the chamfering cutter component to move close to or away from the excircle position at one end of the stator core, and a rotary driving mechanism for driving the chamfering cutter component to rotate around the excircle at one end of the stator core to chamfer the excircle at the end of the stator core. The technical scheme of the invention has the effects of improving the machining efficiency and lowering the production cost.

Description

Technical field [0001] The invention relates to a special chamfering device for a self-locking stator iron core. Background technique [0002] The stator core usually has two forms, namely the clasp type and the self-buckling type. The clasp stator iron core is formed by buckling the punching pieces through cleats to form a whole, and the self-locking stator iron core is formed by interlocking the punching pieces. The buckle forms the whole. The stator core usually needs to be chamfered at both ends of the outer circle so that the subsequent assembly process can be carried out more smoothly. Due to the structure of the self-locking stator core, the punching pieces themselves are buckled together to form a whole. In the prior art, when chamfering the self-locking stator core, the two ends of the self-locking stator core need to be compressed by a hydraulic press. In order to improve the overall stability, it is then transferred to a lathe to chamfer the outer circle at both ends...
