Embodiment
[0047] A kind of sports device for PE ball core polishing in this embodiment, such as figure 1 shown, including
[0048] The radial guide rail mechanism is connected with a polishing mechanism for polishing the PE ball core, which drives the polishing mechanism to move radially;
[0049] An arc guide rail mechanism, on which the radial guide rail mechanism is arranged to drive the radial guide rail mechanism to perform circular motion, and the arc guide rail mechanism is arranged on the ball core positioning mechanism;
[0050] Ball core positioning mechanism, including the center-seeking moving assembly of moving circular arc guide rail mechanism, laser distance sensor 29;
[0051] The polishing mechanism is provided with a polishing cloth wheel 22. The polishing cloth wheel moves in an arc along the surface of the PE ball core. The first laser sensor and the second laser sensor for detecting the surface roughness of the PE ball core are respectively arranged on both sides o...

The invention discloses a PE ball core automatic polishing system and control method based on torque control. The invention solves the problems of complex structure, high operation requirements and poor applicability of PE ball core polishing equipment in the prior art. The system includes a support frame, inside the support frame there is a ball core rotation mechanism that clamps the PE ball core, and a two-degree-of-freedom motion mechanism is arranged on the upper part of the support frame; the two-degree-of-freedom motion mechanism includes a first motion component and a second motion component, the first The moving component is slidably set on the support frame through the ball core positioning mechanism; the polishing mechanism is set on the second moving component, and the polishing mechanism includes a polishing cloth wheel, which moves in an arc along the surface of the PE ball core. Polishing is carried out in the order of ball core clamping, ball core positioning, parameter setting, ball core polishing and stop reset. The invention automatically completes the polishing of the PE ball core, has simple operation, has low requirements on operating experience and technical level of operators, has wide applicability, and ensures high polishing precision.
Description
technical field [0001] The invention relates to the technical field of polishing, in particular to a movement device and a control method for polishing PE ball cores. Background technique [0002] Traditional natural gas pipeline components (including pipes, valves, adapters, flanges, bolts, nuts, gaskets, etc.) Anti-corrosion treatment and daily maintenance. In recent years, the use of non-corrosive polyethylene (PE) materials for natural gas pipeline components has become an increasing trend. Among them, PE ball valves (polyethylene ball valves) have been widely adopted by major gas companies in my country. [0003] PE ball valve is mainly composed of PE ball core and PE pipe fittings. Its product performance (air tightness, flow characteristics, switch torque, opening stability) is directly affected by the roundness and surface roughness of the PE ball core: roundness error and The smaller the surface roughness, the easier it is for the PE ball core to fit with the PE ...
