摘要
本文介紹了設(shè)計(jì)槍管研磨機(jī)的全過程。為了提高槍管內(nèi)孔加工整體質(zhì)量，在對原機(jī)進(jìn)行深入分析的基礎(chǔ)上，研制了一種新型高加工精度的槍研磨機(jī)。該機(jī)器通過兩部分動(dòng)力源分別控制研具的兩個(gè)方向運(yùn)動(dòng)。對整個(gè)傳動(dòng)系統(tǒng)進(jìn)行了分析，包括位移、速度、加速度特征。并用Matlab軟件做出了他們隨曲柄轉(zhuǎn)角變化的曲線。齒輪減速器和帶傳動(dòng)在文中也有涉及。在設(shè)計(jì)完各個(gè)部分的基礎(chǔ)上，進(jìn)行了總體結(jié)構(gòu)布置。新機(jī)器克服了原有機(jī)器的一些缺點(diǎn)，成功提高了傳動(dòng)效率和加工精度。

Abstract
This paper introduces the whole process of the design of the Gun-Pipe grinding mechine. A new type of the Gun-Pipe grinding mechine with high accuracy was designed to develop the machining quality of gun pipe.Two parts of power machine was selected to drive the different motion of the abrasive sticks. Analysis of the whole transmission system was presented in this paper . In this design more attention was paied on the analysis of the crank slipping-piece mechanism movement, including displacement, velocity, acceleration. Then their Matlab-based curves to the angle of the crank were gotten. The design of reductor and belt were also concerned in the process of design. Overall arrangment has been done based on every separated component. The new machine has been finally increased the transmission efficiency and developed the machining quality successfully.

Key words: the crank slipping-piece mechanism Matlab machining accuracy grinding machine
