PE ball core automatic polishing system based on torque control and control method

Abstract

The invention discloses a PE ball core automatic polishing system based on torque control and a control method. The invention solves the problem that PE ball core polishing equipment in the prior artis complex in structure, high in operating demand and narrow in applicability. The system comprises a supporting frame, wherein a ball core rotating mechanism that clamps a PE ball core is arranged inthe supporting frame, and a two-degree-of-freedom moving mechanism is arranged on the upper part of the supporting frame; the two-degree-of-freedom moving mechanism comprises a first moving assemblyand a second moving assembly, and the first moving assembly is slidably arranged on the supporting frame through a ball core positioning mechanism; a polishing mechanism is arranged on the second moving assembly and comprises a polishing cloth wheel, and the polishing cloth wheel performs a circular motion along the surface of the PE ball core. Polishing is performed according to a sequence of ball core clamping, ball core positioning, parameter setting, ball core polishing and stopping resetting. The system polishes the PE ball core automatically, is easy to operate, is low in demand on operating experience and technical level of an operator and wide in application range, and ensures high polishing precision.

Description

technical field [0001] The invention relates to the technical field of polishing, in particular to an automatic polishing system and control method for PE ball cores based on torque control. Background technique [0002] With the rapid advancement of my country's urbanization process, the penetration rate of piped gas is getting higher and higher. Traditional gas pipeline components (including pipes, valves, adapters, flanges, bolts, nuts, gaskets, etc.) are basically made of metal materials, and their biggest disadvantage is that they are susceptible to corrosion (including soil, bacteria, chemical, electrochemical, etc.) Corrosion), etc., requires anti-corrosion treatment and daily maintenance of metal pipeline components, which not only increases operating costs, but also cannot completely avoid the safety hazards of gas pipeline sealing caused by corrosion. In order to effectively avoid corrosion problems, since the 1980s, people have gradually paid attention to and use...
