近几年来、从国外引进的液压动力钳中,钳头咬紧管子常采用内曲线滚子爬坡机构,经使用证明这种咬紧方式结构简单,造型容易,咬紧十分可靠,如进口的H K-500型液压动力钳就是采用这种机构形式。现就这种咬紧机构作受力分析,并建立设计计算方法,供以后 In recent years, the introduction of hydraulic power clamp from abroad, the clamp head clamp often used within the curve of the roller climbing mechanism, the use of such a way to prove that the compact structure, easy to shape, clenched very reliable, such as imports H K-500-type hydraulic power tongs is the use of this form of organization. Now this biting mechanism for force analysis, and the establishment of design and calculation methods for later
