Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] figure 1 This is the structural diagram of the existing stator core press-fitting equipment, which uses an integral indenter, which can easily cause the problem of unbalanced core press-fit coefficients and affect the quality and life of the product.

[0017] figure 2 The structural diagram of the present invention is given. On the workbench 1, a positioning column 2 is provided, on which the iron core laminations 3 are set. On the top of the positioning column 2 is a hydraulic control device 4, that is, a hydraulic cylinder. The evenly distributed floating pressure divider 5 constitutes the pressure head of the equipment. Each floating pressure divider 5 is equipped with a pressure cylinder and connected with its corresponding hydraulic control device 4. The floating pressure divider 5 is connected to the core laminations. The contact surface...

Abstract

This invention discloses a pressing device of a stator iron core with six split floating pressure heads having the advantage of adjusting the pressure separately in the process of pressing including a working stand with a location post on it, stator core lamination jacketing the post, a hydraulic pressure control device is set on top of the post and connected with the head, which is composed of multiple floating sub-heads uniformly distributed in circle connected with their relative hydraulic control devices and a locating device is set on the head of the sub-head.

Description

technical field [0001] The invention relates to a press-fitting device for a stator core of a generator, in particular to a press-fitting device for a stator core with a hexapod floating pressure head. Background technique [0002] At present, the traditional integral indenter is mostly used in the press assembly of the generator stator core. Due to the error in the thickness of the silicon steel sheet itself, and the influence of the thickness of the smear paint film, there are cumulative errors in the process of lamination of the stator core, and sometimes There is a height difference between the yoke and the teeth of the silicon steel sheet, or a "wavy" height difference on the same horizontal plane. If the integral indenter is used, the local looseness of the iron core cannot be accurately judged, nor can it be effectively compensated. The problem of unbalanced core pressing coefficients occurs, which causes the stator to be easily damaged during use and shortens its ser...
