The utility model relates to an adjustable chuck mechanism of a bottle-making machine, which comprises a shaft, a clamp and a clamp seat at the end of the shaft, a slide sleeve sleeve sleeved outside the shaft, a linkage device between the slide sleeve and the clamp claw, a pressure spring is arranged on one side of the slide sleeve leaving the clamp seat, and an adjustment nut is arranged outside the shaft of the slide sleeve near the clamp seat, and the pressure spring presses the slide sleeve to the adjustment nut. The position of the adjusting nut of the above structure can be adjusted on the axis, and the axial position of the adjusting nut defines the limit position of the sliding sleeve, so that the limit position of the sliding sleeve can be adjusted, so that the opening degree of the clamp connected with the sliding sleeve can be adjusted, and the clamping diameter can be adjusted. At the same time, when the adjusting nut is located at different positions on the axis, the compression degree of the pressure spring will be different, and the force acting on the sliding sleeve will be different. This force is transmitted to the clamping claw, so that the clamping force of the clamping claw on the glass tube clamped by it can be adjusted.
【技术实现步骤摘要】
制瓶机可调夹头机构
本技术涉及一种制瓶机夹头机构。
技术介绍
制瓶机夹头机构是制瓶机的重要组成部分,包括有轴、设置在轴端的夹爪、套设在轴外的滑套,滑套与夹爪之间设有联动装置,通过拨叉推动滑套的移动来使夹爪开合,以此对设置在夹爪中的玻璃管实现夹持和松开。最初的制瓶机夹头机构在滑套离开夹爪座的一侧设有压簧,在夹爪座上设有用于滑套限位的凸台结构,压簧将滑套压向该凸台结构。这种制瓶机夹头机构滑套只能在固定的位置之间移动,因此,夹爪的开合的程度也是固定不变的。一套夹头机构只能加工固定直径的工件。CN03269761公开了一种夹爪的夹径可调的制瓶机夹头机构,该技术在滑套外增设一个夹头盘,利用夹头盘的开口和锁定螺钉将夹头盘固定在滑套上,使夹头盘在滑套轴向的位置可调整,夹爪和夹头盘之间设有联动装置。该技术具有如下缺点:夹头盘的固定不易,且在固定夹头盘的时候,该夹头盘的轴向位置调整困难,使得夹爪的夹径的调整的精度不够高。夹爪对不同管径夹持弹簧压力无法调节,造成夹持不同管径玻璃管压力过大或过小不等。
