仪器制造业中,有些机械构件的结构复杂而紧凑。在安装和维修过程中常遇到一些拧螺钉困难的位置。为了装拆螺钉,要花费很多工时。为使生产率提高,有必要改进传统的安装工具。本文介绍国外已有的两种新型起子,经在仪器安装中试用,发现效果很好,有推广的必要。一、可夹持起子它是由1-起子体,2-调节套,3-起子柄,(见图1)三部分组成的。起子体是由横截面为半圆形的两件组合而成。材料为弹簧钢。这两件起子体前半部沿接触平面向左右折
Instrument manufacturing, some mechanical components of the structure is complex and compact. In the process of installation and maintenance often encountered some difficulties screwing position. In order to assemble and disassemble the screws, it takes a lot of man-hours. In order to improve productivity, it is necessary to improve the traditional installation tools. This article describes the two existing foreign new screwdriver, the installation of the instrument in the trial, found that the effect is good, there is a need for promotion. First, it can hold the screwdriver It consists of 1-screwdriver body, 2-adjustment sleeve, 3-screwdriver handle, (see Figure 1) composed of three parts. The screwdriver body is composed of two pieces with a semicircular cross-section. The material is spring steel. The two halves of the front part of the screwdriver fold right and left along the contact plane
