Problems solved by technology

Therefore, the power supply wires used to supply power to the second motor are easily entangled when the rotating disk rotates, resulting in the inability to continue to supply power to the second motor normally.
[0006] (2) The fixture structure setting is relatively simple, and it is impossible to stably support and fix the sphere

Abstract

The invention discloses a ball lapping machine. The ball lapping machine comprises a machine frame; a rotating worktable is arranged on the machine frame; a first motor linked with the rotating worktable is arranged on the machine frame; a clamping rotating mechanism for fixing a ball and driving the ball to rotate is arranged on the rotating worktable; the clamping rotating mechanism comprises a ball clamp for fixing the ball and a second motor for providing a driving force for the ball to rotate; a lapping mechanism for lapping the ball is further arranged on the machine frame; a first service conductor and a second service conductor are arranged on the second motor; the first service conductor sequentially passes through the conductive metal rotating worktable and a conductive metal bearing and is electrically connected to a conductive metal bedplate; the second service conductor is connected to the top of an electric brush contact rod; the bottom of the electric brush contact rod is rotatably and electrically connected with an electric brush piece on the metal bedplate. The ball lapping machine has the advantages that the structural design is reasonable, and the service conductors of the second motor are not twined.

Description

technical field [0001] The invention relates to a processing equipment for ball valve fittings, in particular to a ball grinder. Background technique [0002] The ball is the opening and closing part of the ball valve. In the prior art, in order to improve the sealing performance of the ball valve, the valve seat and the spherical surface of the ball are usually used for matching grinding, so that the cooperation between the sealing surface of the ball and the valve seat can achieve the best fit. [0003] Usually, manual grinding or mechanical grinding is used for grinding the ball, but manual grinding is inefficient and labor-intensive, and the existing mechanical grinding generally only grinds the sealing end of the ball and the valve seat, and cannot realize the comprehensive grinding of the spherical surface , causing the surface of the ball to be uneven, so that when the ball valve is opened or closed, it is easy to wear the valve seat and affect the sealing performance...
