Fixing device for machining welding of plastic valve

Abstract

The invention discloses a fixing device for machining welding of a plastic valve. The fixing device comprises a fixing frame. The top of the fixing frame is provided with a locating pipe. A movable plate is fixedly installed at the left end of the locating pipe. The bottom of the movable plate penetrates through the fixing frame and extends into the fixing frame. A connecting block is fixedly installed at the top of the left side of an inner cavity of the fixing frame and is internally provided with a sliding groove. A sliding block is slidably connected in the sliding groove. According to thefixing device, through arrangement of the locating pipe, the movable plate, the connecting block, the sliding groove, the sliding block, the movable rod, a motor, a rotary disc, a first movable rod and a second movable rod, the position of the locating pipe can be adjusted, through arrangement of a locating sleeve, an adjusting rod and a connecting spring, the locating sleeve can be adjusted, then the plastic valve is fixed, and meanwhile, the problems that stability is poor during fixing, deviation is liable to occur after to-be-connected plastics are molten, cooled and fixed, and use for people is inconvenient are solved.

Description

technical field [0001] The invention relates to the technical field of plastic valve processing, in particular to a fixing device for plastic valve processing and welding. Background technique [0002] With the continuous development of the current social economy, people's living standards are also constantly improving, and the pursuit of quality of life is getting higher and higher, especially in the field of valves, in order to reduce the losses caused by oil pipelines and liquid transportation, Pipeline transmission is often selected in order to more effectively reduce the loss in the transmission process. At the same time, the general pipeline connection is controlled by valves. Most of the valve parts used now are made of metal. The liquid is extremely corrosive, and the metal valve is also easily affected by the outside air, resulting in a limited service life. Due to actual use needs, the two-way plastic valve needs to be improved to a three-way. The parts to be conn...
