Description
Technical Field
[0001] The utility model relates to the technical field of automation and intelligentization of steel ball equipment, in particular to a horizontal steel ball grinding machine with an auxiliary grinding disc for positioning. Background Art
[0002] Most horizontal steel ball grinding machines use hydraulic drive and pressure. Because of its stable transmission, large load-bearing capacity and convenient operation, it has been widely used in steel ball equipment. When processing steel balls, the steel ball equipment needs to have a small pressure between the two plates and a slow spindle speed at the beginning to allow the steel balls to go along the groove. After the groove is completed, the high pressure and high speed are adjusted for grinding. When the steel balls are processed to size, the two tooling plates need to be disengaged so that the workers can unload the steel balls between the two plates. When the next batch of steel balls of the same specification is processed, the first step needs to be repeated, which is troublesome, time-consuming, labor-intensive, and prone to errors. When the displacement sensor is used for auxiliary positioning, the oil is easy to heat up, the viscosity of the oil will increase the internal leakage of the oil pump, and the friction loss between the piston sleeve and the components cannot guarantee that the electrically controlled displacement sensor can stop the spindle at the working position of the previous processing cycle every time (the error exceeds 1mm), thereby increasing the difficulty of operation, reducing the processing accuracy and efficiency of the steel balls, and is not conducive to the development of automation and intelligence of steel ball equipment.
