Description

Technical Field

[0001] This utility model relates to the technical field of vertical steel ball machines, and in particular to a steel ball machine drive device with a wide range of adjustable output speed. Background Technology

[0002] A steel ball milling machine, also known as a polishing milling machine, is a machine that uses the grinding principle to process ball blanks into steel balls of the same size and with a certain surface finish. Vertical steel ball milling machines are the most commonly used steel ball processing equipment. Existing steel ball milling machines, such as the one described in the utility model patent CN212192494U, include an upper grinding plate, a lower grinding plate, and an outer disc. The upper and lower grinding plates are respectively provided with corresponding annular grooves. An inlet and outlet are located at one corner of the upper grinding plate. The outer disc has a feeding and discharging mechanism corresponding to the inlet and outlet. The upper grinding plate presses down, the lower grinding plate rotates forward, and the outer disc rotates in the opposite direction. The feeding and discharging mechanism divides the inlet and outlet into an inlet and an outlet. The ball blank enters the annular groove from the inlet for grinding, leaves the annular groove from the outlet and enters the outer disc, and is then driven by the outer disc back into the inlet to achieve the circulation of the ball blank. When the steel ball machine processes steel balls of different specifications, the upper and lower grinding discs are replaced, and the reverse rotation speed of the outer disc is adjusted. The existing power sources that drive the outer disc to rotate in the reverse direction are mostly variable frequency motors. However, the speed adjustment range of variable frequency motors is limited and cannot meet the speed adjustment requirements of the outer disc, which limits the range of steel ball specifications that a single steel ball machine can process.
