Four-dimensional skate edge grinding apparatus

Abstract

The invention discloses a four-dimensional ice skate sharpening device, which is characterized in that a bracket (2) and a moving platform (8) are connected through three moving branched chains (5, 6, 7) with same structures; in the moving branched chains, four connecting rods (14, 15, 16, 21) are connected with four rotating pairs to form a parallelogram mechanism respectively; the connecting rod (14) is connected with the moving platform (8) through a first rotating pair (13), the connecting rod (16) is connected with a connecting plate (17) fixedly connected with the front end of a guide bar (18) through a second rotating pair (20), and the connecting plate (17) is connected with a push rod of a linear motor (19); and an angle control motor (9) is arranged on the moving platform (8), an oil stone support (4) is connected with an output shaft of the angle control motor (9), and an oil stone or an emery stick (3) is arranged on the oil stone support (4). Through the driving of the three linear motors (19) on the three moving branched chains (5, 6, 7) and the angle control motor (9) arranged on the moving platform (8), three-dimensional movement and one-dimensional rotation of theoil stone or the emery stick (3) can be achieved. The four-dimensional ice skate sharpening device has the advantages of concise structure, good manufacturability for machining and assembling, and the like, and can obtain ideal surface roughness of the ice skate edge and crossing surface texture.

Description

technical field [0001] The invention relates to sports equipment, in particular to a sharpening device suitable for ice skate blades in ice sports. Background technique [0002] Ice skates are important equipment for ice sports. When skating on the ice, the smaller surface roughness of the blade and the cross-shaped surface texture are conducive to reducing friction and increasing the skating speed. As the skating progresses, the edge of the blade becomes dull and the contact between the blade and the ice surface gradually deteriorates. At this time, the ice blade needs to be re-sharpened to obtain the ideal surface roughness and grain direction of the blade. The correct sharpening method is one of the important ways to prolong the service life of ice skates and improve sports performance. [0003] At present, the sharpening method of ice skates is mainly manual grinding. When grinding, the whetstone or sand bar is required to make an "8" movement relative to the blade to o...
