Outer sizing die quick-changing mechanism
Technical field: the invention belongs to the electrical machine equipment technical field, be specifically related on a kind of coil shaper the outer sizing die quick-changing mechanism for the shaping of stator end coil external circle.
Background technology: in the manufacturing process of motor, motor stator needs to carry out the regular shaping of end coil after embedding coil, the end coil cylindrical shaping of in the past using is to move and carry out the cylindrical shaping by the slide block in slide, when being die change, its shortcoming slide integral body need be pulled down, and then dismantle slide block, work loaded down with trivial details, efficiency is low, can not meet the requirement of production.
Summary of the invention: the purpose of this invention is to provide that a kind of simple in structure, die change is convenient, the outer sizing die quick-changing mechanism of reliable in action.
Technical scheme of the present invention is: a kind of outer sizing die quick-changing mechanism, be provided with slide on substrate, be laid with some radially saturating grooves on slide, establishing pressing plate on saturating groove is enclosed in slide block in groove and can radially slides, it is characterized in that: lining is equipped with in slide inner chamber lower end, in the cavity of excircle of bushing and slide block inboard, establishes back-moving spring; The slide block lower surface is connected by positioning key and shaping block, and shaping block inner chamber is connected as a single entity through little cover and outer dressing stick; The slide cylindrical is equipped with tapered sleeve, is laid with a plurality of compressor arms on the tapered sleeve upper surface, and the compressor arm upper end is passed with the power plate of trimmer and is connected by pilot hole corresponding on substrate.
Owing to having adopted technique scheme, it is to be fixed on the slide block lower surface after outer dressing stick and shaping block are connected, thereby has advantages of that die change convenience, reliable in action, efficiency are high.
Accompanying drawing explanation: technical scheme of the present invention is done into step detailed description one by one below in conjunction with the drawings and specific embodiments.Accompanying drawing is structural representation of the present invention.
Embodiment: with reference to accompanying drawing.1, a kind of outer sizing die quick-changing mechanism, at substrate 2 upper saddles 11, uniformly on slide 11 be laid with some radially saturating grooves, establishing pressing plate 10 on saturating groove is enclosed in slide block 7 in groove and can radially slides, lining 12 is equipped with in slide 11 inner chamber lower ends, in the cavity of lining 12 cylindricals and slide block 5 inboards, establishes back-moving spring 4; Slide block 5 lower surfaces are connected by positioning key 7 and shaping block 8, and shaping block 8 inner chambers are connected as a single entity with outer dressing stick 9 through little cover 6; Slide 11 cylindricals are equipped with tapered sleeve 3, are laid with a plurality of compressor arms 1 on tapered sleeve 3 upper surfaces, and compressor arm 1 upper end is passed with the power plate of trimmer and is connected by pilot hole corresponding on substrate 2.
During use, tapered sleeve endwisely slips along the slide cylindrical under the effect of exterior power, and pressed slider makes it shrink to mesopore simultaneously, and outer dressing stick extruding coil external circle reaches the purpose of shaping; When die change, can directly unclamp the hold-down screw of shaping block and slide block, change dressing stick and get final product.
