棘轮式自动点焊装置是为点焊拖拉机零件内密封罩用(图1)。罩是两个厚3毫米的冲压件合成。原来是用样板定位后,由工人掌握点焊,不但劳动强度很大,而且因卡装样板增加了辅助时间,生产率很低。新安装的棘轮式自动点焊装置上有定位块9,使焊作能自动定位和固紧。机构主要分成两部分:第一部分是利用点焊机 Ratchet automatic spot welding device is used for spot welding tractor parts sealed enclosure (Figure 1). Cover is two thick 3 mm stamping composite. The original is the template positioning, by the workers to master the spot welding, not only labor-intensive, but also because of the card model to increase the auxiliary time, low productivity. The newly installed ratchet automatic spot welding device has a positioning block 9, so that welding can be automatically positioned and fastened. The main body is divided into two parts: The first part is the use of spot welding
