硬质合金刮削滚刀钎焊后的刀片位置精度是重要的技术指标之一,因它可减少机加工的磨削余量,便于铲磨,降低制造成本。本文着重介绍了硬质合金刮削滚刀真空钎焊夹具的结构特点、设计要领、注意事项。对于m3.5～20的硬质合金刮削滚刀,利用此种结构的钎焊夹具,焊后的刀片螺旋位置偏差在0.3～0.5毫米之内。因此,它对于采用整体加热钎焊制造硬质合金刮削滚刀的厂家有一定的参考价值。 Carbide scraper hob after brazing blade position accuracy is one of the important technical indicators, because it can reduce machining allowance grinding, easy to shovel, reduce manufacturing costs. This article focuses on the structural features, design essentials, precautions of carbide brazing hob vacuum brazing fixture. For m3.5 ~ 20 carbide skiving hobs, the use of such structure brazing fixture, after welding the blade position deviation within the screw 0.3 to 0.5 mm. Therefore, it has a certain reference value for the manufacturers adopting the overall heating brazing to produce the carbide shaving hob.
