【技术实现步骤摘要】
不停车且一次性车削工件的顶针
:本技术涉及一种不停车且一次性车削工件的顶针。
技术介绍
:车床作为机械加工必不可少的设备,被人们所广泛使用,车床顶针的作用是顶置中心,并担负工件重量和承受切削力,但实际生产中由于顶针死顶,使工件和顶尖摩擦过热,从而容易顶弯工件,甚至会将中心孔烧坏。
技术实现思路
:鉴于上述现有技术的不足,本技术的目的在于提供一种不停车且一次性车削工件的顶针,该不停车且一次性车削工件的顶针结构简单、设计合理,有利于实现不停车装夹工件,并避免工件和顶尖摩擦过热。本技术不停车且一次性车削工件的顶针,其特征在于:包括插置在机床主轴端头槽孔内的本体,所述本体第一端为插入机床主轴端头槽孔内的锥形套,所述本体第二端呈罩形并与顶针座相套接,所述锥形套体内设有螺纹孔,所述螺纹孔体内依次设有螺塞、螺母和顶杆,所述顶杆朝向工件的一端头设有用于插入阶梯杆一端的凹槽孔道,所述阶梯杆的另一端与设在顶针座中心孔内的顶针连接,所述顶针座和本体第二端外围套设有导套,本体第二端罩形开口底端依次设有橡胶垫和弹性座,所述弹性座端面与顶针座端面之间的腔体内填充有钢珠,所述顶杆与阶梯杆之间设有弹 ...
