Self-balancing PE ball core polishing machine

Abstract

The invention discloses a self-balancing PE ball core polishing machine. The machine is composed of a PE ball core clamping device and a polishing wheel feeding device, PE ball cores are respectivelyclamped on the left side and the right side of the PE ball core clamping device, the left side and the right side of the polishing wheel feeding device drive polishing wheels respectively, and synchronous polishing and feeding are conducted on the two PE ball cores. Due to the fact that the vibration force on the left side and the right side can be counteracted in the polishing process, meanwhile,the residual unbalanced force can be removed through pose adjustment of the arch-shaped support, and high-precision PE ball core polishing can be achieved without interference of the vibration force.In addition, the two PE ball cores are polished at the same time, and therefore the polishing efficiency is twice that of a traditional machine. The polishing machine has the characteristics of highefficiency and high precision, so that the polishing machine is applied to full-automatic polishing of the PE ball core, the production efficiency and the product quality grade of the PE ball core canbe greatly improved, and remarkable economic and social benefits are brought.

Description

technical field [0001] The invention relates to a PE ball core polishing machine, in particular to a self-balancing PE ball core polishing machine. Background technique [0002] The use of PE (polyethylene) materials instead of metal materials to make natural gas pipeline components (including pipes, valves, adapters, flanges, bolts, nuts, gaskets, etc.) is an important technological change in the natural gas transportation industry. PE material has the advantages of good toughness, strong corrosion resistance, high shock resistance, small pipe wall friction coefficient, etc., and also has good resistance to crack growth, which greatly improves the corrosion resistance of natural gas pipe fittings. PE ball valve is one of the important parts of natural gas pipe fittings. It is composed of PE ball core and PE pipe fittings. Its product performance (air tightness, flow characteristics, switch torque, opening stability) etc. The direct impact of surface roughness: the smaller ...

AI Technical Summary

Problems solved by technology

In recent years, the industry has started the research and development of PE ball core automatic polishing machine. This machine can replace manual and fully automatic PE ball core polishing, which greatly improves the polishing efficiency of PE ball core. However, due to the installation gap of PE ball core (that is, the PE ball core is not strictly a sphere), resulting in strong vibration of the PE ball core during the polishing process, which in turn makes it difficult to control the polishing pressure between the polishing wheel and the PE ball core during the polishing process, and eventually leads to the PE ball core Polishing accuracy (i.e. surface roughness) does not meet expectations
