A welding positioning device for hydraulic cylinder machining

Abstract

The utility model relates to a kind of welding positioning device for hydraulic cylinder processing, belong to hydraulic cylinder processing technical field, including workbench, the top of workbench is connected with fixed sleeve and penetrates, the top of fixed sleeve is fixedly connected with sliding frame, the inside of sliding frame is slidably connected with a pair of backboards, the front side of backboard is fixedly connected with fixed block, the front side of fixed block is fixedly connected with second clamping plate, the backside of second clamping plate is connected with shaft rod, the outside of shaft rod is rotatably connected with shaft sleeve, the outside of shaft sleeve is fixedly connected with first clamping plate, the annular clamping space size formed by two groups of clamping plates is changed by the stroke adjustment of first electric push rod, second electric push rod, when facing small diameter cylinder barrel, extend push rod stroke, reduce clamping aperture, without replacing clamping plate can be adapted to different diameter cylinder barrel, substantially reduce the positioning threshold of non-standard diameter cylinder barrel, and the adaptation flexibility is significantly improved.
