【摘要】：鉤舌作為車鉤的重要組成部分,其表面的修復(fù)對列車在運行過程中的安全性和穩(wěn)定性有很重要的意義。鉤舌磨損表面通常用堆焊進(jìn)行修復(fù),而手工堆焊效率低,焊接質(zhì)量差,為了提高鉤舌表面修復(fù)效率,保證焊接質(zhì)量的穩(wěn)定,本文研制了一種自動堆焊鉤舌表面的控制系統(tǒng).系統(tǒng)以觸摸屏作為人機交互界面,作為焊接生產(chǎn)過程中的控制界面,簡潔方便且控制精確,還可根據(jù)鉤舌表面磨損程度的不同,通過觸摸屏設(shè)定相關(guān)焊接參數(shù)。系統(tǒng)以單片機作為控制核心,運算能力強,可擴(kuò)展性高。本文詳細(xì)介紹了以單片機DSPIC30F6011A為控制核心的鉤舌自動堆焊控制系統(tǒng)的硬件電路和軟件程序設(shè)計。其中硬件電路主要包括單片機的基本工作電路,觸摸屏與單片機的通訊電路,焊槍和鉤舌位移采集電路以及電動機控制電路等。軟件程序設(shè)計主要包括單片機與觸摸屏之間的通訊程序和觸摸屏界面按鈕的執(zhí)行程序。硬件電路與軟件程序的調(diào)試結(jié)果顯示,本系統(tǒng)在設(shè)定的絕對坐標(biāo)系統(tǒng)下可以實現(xiàn)鉤舌表面的自動焊接,且焊縫質(zhì)量基本滿足鉤舌堆焊的工藝要求,提高了鉤舌堆焊效率的同時也穩(wěn)定了堆焊質(zhì)量。
[Abstract]:As an important part of coupler, the surface repair of hook tongue is very important to the safety and stability of train. The worn surface of hook tongue is usually repaired by surfacing welding, but the efficiency of manual surfacing welding is low and the welding quality is poor. In order to improve the repair efficiency of hook tongue surface and ensure the stability of welding quality, a control system for automatic surfacing of hook tongue surface is developed in this paper. The system takes the touch screen as the man-machine interface and the control interface in the welding production process, which is simple, convenient and accurate. It can also set the relevant welding parameters through the touch screen according to the different wear degree of the hook tongue surface. The system takes single-chip computer as the control core, which has strong operation ability and high expansibility. This paper introduces in detail the hardware circuit and software program design of the automatic surfacing welding control system with single chip computer (DSPIC30F6011A) as the control core. The hardware circuit mainly includes the basic working circuit of the single chip microcomputer, the communication circuit between the touch screen and the single chip microcomputer, the displacement acquisition circuit of welding gun and hook tongue, the motor control circuit and so on. The software program design mainly includes the communication program between MCU and touch screen and the executing program of touch screen interface button. The debugging results of hardware circuit and software program show that the system can realize automatic welding of hook tongue surface under the system of absolute coordinates, and the welding quality basically meets the technological requirements of hook tongue surfacing welding. The efficiency of hook-tongue surfacing is improved and the surfacing quality is stabilized.
