拉伸试件划线机
摘要：
本发明公开了一种拉伸试件划线机，包括底座(1)、设置于底座上方的划针总成安装架(2)以及划针总成，其特征在于：所述划针总成安装架(2)通过套杆套装在底座上方，并可在套杆上上下滑动；划针总成安装架(2)横向设置有一均匀排列的划针安装螺纹孔(5)，每个划针安装螺纹孔(5)上装有划针(6)，所述划针总成由针头(61)、针头联接件(62)、弹簧件(63)以及顶部螺钉(64)构成；底座(1)上还设置有固定试件径向移动的V型槽(7)和限定试件轴向移动的挡板(8)。本发明设置有多个划针针头，划针总成被分别固定在划针总成安装架上，当试件转动时，11个针头同时在试件上划线，当试件被转动一圈，便完成试件的十等分标距，使用十分方便。
摘要（英）：

The invention discloses a tensile specimen scribing machine which comprises a base (1), a scriber assembly installation rack (2) and scriber assemblies and is characterized in that the scriber assembly installation rack (2) is sleeved above the base via a loop bar and can slide on the loop bar up and down; the scriber assembly installation rack (2) is horizontally provided with scriber installation screwed holes (5) in uniform arrangement; each scriber installation screwed hole (5) is provided with a scriber (6); and each scriber assembly comprises a pinhead (61), a pinhead coupler (62), a spring piece (63) and a top screw (64), and the base (1) is also provided with a V-shaped groove (7) for fixing the radial movement of a speciment and baffle (8) for preventing the specimen from axial movement. In the invention, multiple scriber pinheads are arranged, the scriber assemblies are respectively fixed on the scriber assembly installation rack, when the specimen rotates, 11 pinheads scribe on the specimen at the same time, and when the specimen rotates for a circle, the decile gauge length of the specimen can be completed, thus the tensile specimen scribing machine is convenient in use.
