PLC (programmable logic controller) control-based screw driving skating blade sharpening device

Abstract

The invention relates to a PLC control-based screw driving skating blade sharpening device and belongs to the field of sports equipment. The PLC control-based screw driving skating blade sharpening device is mainly composed of a support, a skating blade rack, three branch motion chains and an oilstone, wherein the three branch motion chains are in an X direction, a Y direction and a Z direction respectively, and the X-directional branch motion chain and the Y-directional branch motion chain are identical in structure and are respectively composed of a ball screw nut pair and a linear guide rail; the X-directional branch motion chain is fixed onto the slider of the Y-directional branch motion chain to achieve motion inside an XOY plane; in the Z-direction, the oilstone moves along with theshape change of a skating blade. The PLC control-based screw driving skating blade sharpening device has the advantages of being compact in structure, novel in conception, convenient to use, easy to maintain, good in assembling property and high in practicality, and can set an oilstone motion track as required to help acquire ideal blade surface roughness and cross-shaped surface texture, therebybeing applicable to daily grinding maintenance of the skating blade.

Description

technical field The invention relates to the field of sports equipment, in particular to a speed skating blade sharpening device, in particular to a PLC-based screw driven ice blade sharpening device. Background technique Ice skates are the main sports equipment for ice sports. The surface finish and cross texture of the blade affect the friction force, which in turn affects the speed of movement, and even determines the athlete's competition performance. At present, most of the existing domestic skate sharpening devices are manual or semi-automatic skate sharpening devices, and the limitations of manual devices are self-evident. Now emphatically set forth the limitations of the semi-automatic skate sharpening device with a typical inventive device. The control system of the portable CNC ice skate grinding machine developed by the Heilongjiang Provincial Institute of Sports Science is complex in programming, difficult to operate, expensive, and the surface texture of the b...

AI Technical Summary

Problems solved by technology

1. Devices with a low degree of automation mostly use rotating grinding wheels to grind the blade, which has low precision, non-adjustable motion stroke and trajectory, and cannot achieve precise control and high energy consumption; 2. The algorithm with a high degree of automation is complex, difficult to operate, and expensive Expensive, 3. Poor versatility
