一种用于船舶精拉线轴孔测量与定位的装置

Device for measuring and positioning fine-wire-drawing shaft holes of ship

Abstract

本发明公开了一种用于船舶精拉线轴孔测量与定位的装置,包括与舶艉管座前后端面相配合的圆盘,所述圆盘表面设置有呈十字型的四把钢直尺,所述钢直尺的基点与圆盘的圆心重合,本产品能准确、快捷的对船舶艉轴轴孔测量与定位,可一次性同时的读取轴孔上下左右四点的数值,使船舶艉轴精拉线一次性通过得到保证,有效的避免了以往船舶精拉线轴孔测量时需逐一的对轴孔的上下左右的读数,读数时可能因孔心基准点的变动而导致读数的错误,造成返工。从而加快了坞期进度。另本产品制作轻巧,便于携带,因此可以广泛应用于船舶艉轴轴孔的测量与定位。
The invention discloses a device for measuring and positioning fine-wire-drawing shaft holes of a ship, which comprises a round disc, wherein the round disc is matched with the front end surface and the rear end surface of a pipe seat of a ship stern; the surface of the round disc is provided with cross-shaped four steel rulers; and base points of the steel rulers are coincided with the center of the round disc. According to the device, the shaft holes of a ship stern shaft are measured and positioned accurately and quickly, the values of four points at the upper parts, the lower parts, the left parts and the right parts of the shaft holes can be read simultaneously once, so that the one-time completion of fine wire drawing of the ship stern shaft is guaranteed, and the conditions that the values of the upper parts, the lower parts, the left parts and the right parts of the shaft holes need to be read one by one in measurement of the fine-wire-drawing shaft holes of the ship, and the wrong reading due to change of the datum points at the centers of the holes causes reworking possibly are effectively avoided. The device is light and handy and convenient to carry so as to be widely applied in measuring and positioning the shaft holes of the ship stern shaft.
