The utility model discloses a sectional support fixed adjustment device, which comprises a lower chuck, a steel pipe, a threaded steel pipe, a screw, a round steel handle and an upper chuck. The upper end of the lower chuck and the lower end of the upper chuck are respectively welded together with the steel pipe. The upper end of the steel pipe connected by the lower chuck and the lower end of the steel pipe connected by the upper chuck are respectively fixed with the threaded steel pipe, and the upper and lower ends of the steel pipe connected by the upper chuck are respectively connected with the thr There is a screw between them. The middle part of the screw is connected with a round steel handle. The upper and lower ends of the screw are provided with threads, which are respectively matched with the threaded steel pipe above and below the screw. The screw is screwed into the threaded steel pipe through threads. The upper and lower ends of the screw are set in opposite directions. The rotation of the round steel handle can drive the screw to rotate, while the threaded steel pipe is matched with the threads inside the screw. In addition, the reverse setting of the internal threads at both ends of the screw leads to the reverse movement between the upper and lower threaded steel pipes. The adjusting device can accurately adjust the accuracy of the sectional opening.

一种分段支撑固定调节装置
本技术涉及一种分段支撑固定调节装置。
技术介绍
现代造船的每一道工序都必须进行有效的尺寸精度控制,否则难以保证正常的生产过程和船舶的各项技术性能。就尺寸精度的控制意义来说,大型船舶、特种船舶和工作条件比较恶劣的船舶对此要求更为严格。目前分段支撑普遍还是采用简单的槽钢或者角钢焊接固定支撑,对于严格的精度控制很难保证,而且焊接过程中容易造船母材的损伤,大量的使用槽钢或者角钢也造成了成本的浪费,对于精度的控制很不利,也制约着船厂的发展,能进行有效的精度控制,对于提高船厂的竞争力很有帮助。
