Embodiment Construction

[0013] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0014] As shown in the figure, a ball grinder includes a frame 1, on which a rotating disk 2 is arranged, and the rotating disk 2 is driven to rotate by the first motor 3 at the bottom, and the rotation of the rotating disk 2 can drive the ball 15 rotate rapidly around a vertical axis.

[0015] The rotating disc 2 is provided with a clamping and rotating mechanism capable of clamping the sphere 15 and driving the sphere 15 to rotate. The clamping and rotating mechanism includes a support 4 fixedly arranged on the rotating disc 2 and a thimble 5 arranged on the support 4 , the rotating shaft 6 and the clamp 7 installed on the rotating shaft 6, the thimble 5 withstands the two ends of the rotating shaft 6, one of the thimble 5 is connected with the second motor 8, and the clamp 7 is fixedly matched with the inner wall of the sphere 15 channel , the ball 15 is...

Abstract

The invention provides a ball body grinding machine, which is characterized in that a rotating work table is arranged on a machine frame, a clamping rotating mechanism capable of clamping a ball body and driving the ball body to rotate is arranged on the rotating work table, a grinding mechanism used for grinding the ball body is also arranged on the machine frame, the grinding mechanism comprises a driving shaft and a connecting shaft, the connecting shaft is used for connecting the valve seat, and the driving shaft and the axial line center of the connecting shaft are not positioned in the same axial line and are in linkage connection through a connecting element. The ball body grinding machine has the advantages that the structure is simple and reasonable, the whole ball surface can be ground, and the grinding precision can be improved, so the ball body can be tightly matched with the valve seat in any state, and the integral sealing performance of the ball valve is improved.

Description

technical field [0001] The invention relates to valve processing equipment, in particular to a ball grinder. Background technique [0002] The ball valve is a valve whose opening and closing part is a sphere, which is driven by the valve stem and rotates around the axis of the valve stem. Ball valves are used in many pipelines to control the pressure, flow and direction of fluid. For most valves, the sealing problem is the primary problem, and the sealing performance of ball valves is very high, so the requirements for the spherical surface are also very high. Usually, the spherical surface of the valve seat and the ball is 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, the grinding of the ball of the ball valve usually adopts manual grinding or mechanical grinding, but the work efficiency of manual grinding is low and the labor intensity is high, while the existing ...
