Description

一种新型汽车排气系统防焊接变形工装
技术领域
本实用新型属于汽车排气系统制造技术领域，具体涉及一种新型汽车排气系统防焊接变形工装。
背景技术
汽车排气系统的最前端是排气歧管和歧管法兰，排气歧管通过歧管法兰来与发动机气缸体相连，将各缸的排气通过排气歧管集中导入排气总管；歧管法兰为细长带有进气口法兰结构，与排气歧管焊接后，由于焊缝的热应力引起的焊接变形较难控制，影响后续装配，焊后矫形浪费了大量人力物力，所以传统焊接工装对焊接变形的控制亟待改进。
发明内容
本实用新型的目的是为了解决歧管法兰与排气歧管焊接变形的问题，提供了一种新型汽车排气系统防焊接变形工装，其技术方案如下：
一种新型汽车排气系统防焊接变形工装，它包含底板、法兰安装板和歧管定位夹具，法兰安装板通过支撑座来固定连接在底板上，歧管定位夹具设置在法兰安装板的上方，歧管定位夹具包含左右两个定位压头，两个定位压头分别与一个开合控制气缸连接，每个开合控制气缸分别与制动机构连接；围绕法兰安装板设置有多个法兰压紧机构，每个法兰压紧机构包含L形基座、液压缸、传动块和法兰压板，液压缸固定连接在L形基座上，L形基座与底板固定连接，传动块的两端分别与L形基座和液压缸的伸缩杆铰接，法兰压板与传动块固定连接，液压缸的伸缩杆伸长时驱动法兰压板压紧法兰；在法兰安装板的底部设置有冷却水循环管；在底板上设置有气阀和气液增压缸，气阀的入口连接气源，气阀的出口分别连接气液增压缸和两个开合控制气缸的入口，气液增压缸的出口通过转接器与全部液压缸的入口连接。
本实用新型的有益效果为：结构紧凑、设计合理，增加了法兰压紧机构并采用气液增压缸增加压力，提高了歧管法兰的稳定性，能压紧歧管法兰变形风险区域，减小了歧管法兰焊后翘角变形的风险；焊接时，冷却水循环管内接入循环水，能及时有效的散发转移法兰安装板的焊接热量，进一步避免了热应力引起的焊接变形；能够有效控制歧管法兰与排气歧管焊接后产生的变形，保证歧管法兰的尺寸误差在允许范围内，提高产品质量，减少工作人员焊后的矫形工作量，提高生产效率。
附图说明：
图1是本实用新型的使用状态示意图；
图2是图1的后侧视角示意图；
图3是一个法兰压紧机构结构示意图；
图4是冷却水循环管的结构示意图。
具体实施方式：
参照图1至图4，一种新型汽车排气系统防焊接变形工装，它包含底板1、法兰安装板2和歧管定位夹具，法兰安装板2通过支撑座2-1来固定连接在底板1上，歧管定位夹具设置在法兰安装板2的上方，歧管定位夹具包含左右两个定位压头3，两个定位压头3分别与一个开合控制气缸4连接，每个开合控制气缸4分别与制动机构4-1连接；围绕法兰安装板2设置有多个法兰压紧机构5，每个法兰压紧机构5包含L形基座5-1、液压缸5-2、传动块5-3和法兰压板5-4，液压缸5-2固定连接在L形基座5-1上，L形基座5-1与底板1固定连接，传动块5-3的两端分别与L形基座5-1和液压缸5-2的伸缩杆铰接，法兰压板5-4与传动块5-3固定连接，液压缸5-2的伸缩杆伸长时驱动法兰压板5-4压紧法兰；在法兰安装板2的底部设置有冷却水循环管6；在底板1上设置有气阀7和气液增压缸8，气阀7的入口连接气源，气阀7的出口分别连接气液增压缸8和两个开合控制气缸4的入口，气液增压缸8的出口通过转接器9与全部液压缸5-2的入口连接。
优选的是，在气阀7与法兰安装板2之间设置有防护板7-1，防止焊接过程中损坏气阀7。
