The invention discloses an HPB300 round steel holding clamp. The HPB300 round steel holding clamp comprises holding clamp bodies, an adjusting shaft rod a, a connecting shaft rod a, a connecting shaftrod b and an adjusting shaft rod b, wherein the two holding clamp bodies are arranged in total, and the two holding clamp bodies are arranged in parallel to each other; the adjusting shaft rod a, theconnecting shaft rod a, the connecting shaft rod b and the adjusting shaft rod b are connected to the rotation adjusting positions of the two holding clamp bodies; and a first self-locking mechanismfor self-locking and limiting the adjusting shaft rod b and the adjusting shaft rod a is rotationally connected to the middle end of the adjusting shaft rod b. According to the HPB300 round steel holding clamp, the first self-locking mechanism and a second self-locking mechanism are arranged on the connecting shaft rod b or the adjusting shaft rod b, the first self-locking mechanism limits and fixes the adjusting shaft rod b and the adjusting shaft rod a, and the second self-locking mechanism limits and fixes the connecting shaft rod b and the connecting shaft rod a, so that self-locking and fixing of the two holding clamp bodies are achieved, the stability of the holding clamp bodies for clamping round steel is enhanced, and the safety during operation is improved.

    本发明公开了一种HPB300圆钢抱夹,包括:抱夹夹具、调节轴杆a、连接轴杆a、连接轴杆b和调节轴杆b;所述抱夹夹具共设有两个,且两个抱夹夹具相互平行设置;所述调节轴杆a、连接轴杆a、连接轴杆b和调节轴杆b连接在两个抱夹夹具转动调节位置处;所述调节轴杆b中端位置处转动连接有对调节轴杆b和调节轴杆a进行自锁限位使用的第一自锁机构。本发明中,在连接轴杆b或调节轴杆b设置第一自锁机构和第二自锁机构,第一自锁机构和第二自锁机构分别对连接轴杆b和连接轴杆a以及调节轴杆b和调节轴杆a进行限位固定,从而实现对两个抱夹夹具进行自锁固定,增强抱夹夹具对圆钢夹持的稳定性,提高作业时的安全性。
