我厂是生产凤凰牌B型自行车中轴的专业厂。在中轴的两端两侧各有一槽要铣削加工,两槽的底平面要求平行,每年的生产量为3～4百万件。为提高生产率,我们设计一种液性塑料多件夹紧专用夹具,经几年来的应用,收到了良好的效果。一、夹具结构夹具由V形块、压紧块、夹具体、柱塞、夹紧系统和增压系统组成。其主要特点是:为保证6根中轴同时压紧,故必须在夹具体4内腔注以液性塑料,使6个压紧块5互相浮动,对工件进行压紧,增压系统
I plant is the production of Fenghuang B-axis professional shaft factory. There is a groove on each side of both ends of the central shaft for milling, the bottom plane of the two grooves requires parallel, and the annual production volume is 3 to 4 million pieces. In order to improve the productivity, we design a kind of liquid plastic multi-piece clamp special fixture, after several years of application, we have received good results. First, the fixture structure The fixture consists of V-shaped block, compacting block, clamp body, plunger, clamping system and booster system. Its main features are: In order to ensure the simultaneous compression of the 6 central axis, it must be in the clamp body 4 injection liquid plastic, so that the six clamping blocks 5 float to each other, the workpiece is pressed, the pressurization system
