Ball grinding machine with grinding force adjusting function

Abstract

The invention discloses a ball grinding machine with a grinding force adjusting function. The ball grinding machine comprises a rack. The rack is provided with a rotary workbench and a first motor in linkage with the rotary workbench. The rotary workbench is provided with a clamping and rotating mechanism used for fixing a ball and driving the ball to rotate. The clamping and rotating mechanism comprises a ball clamp for fixing the ball and a second motor used for providing drive force for ball rotation. The rack is further provided with a grinding mechanism used for grinding the ball. The second motor is provided with a first power supply wire and a second power supply wire. The first power supply wire sequentially penetrates the conductive metal rotary workbench and a conductive metal bearing to be electrically connected to the conductive metal table plate. The second power supply wire is connected to the portion above an electric brush feeler lever. The lower portion of the electric brush feeler lever is rotationally and electrically connected with an electric brush sheet on the metal table plate. The ball grinding machine has the advantages that the structural design is reasonable and the power supply wires of the second motor cannot be twisted.

Description

Technical field [0001] The invention relates to a processing equipment for ball valve fittings, in particular to a ball grinder with a grinding force adjustment function. 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 and grinding to achieve the best fit between the sealing surface of the ball and the valve seat. [0003] Generally, manual grinding or mechanical grinding is usually used to grind the sphere, but manual grinding is inefficient and labor-intensive. The existing mechanical grinding generally only grinds the sealing end of the sphere and the valve seat, which cannot achieve full grinding of the spherical surface. , Resulting in uneven surface of the ball, so that when the ball valve is opened or closed, it is easy to wear the valve seat and affect the sealing perform...

AI Technical Summary

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
