Embodiment Construction

[0019] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0020] Such as Figure 1-3 Shown is the best embodiment of the present invention, a ball core high-efficiency grinding device, including a base 1, a frame 2, a positioning mandrel 3, a mandrel driving motor 4, a ball core 5, a grinding disc 6 and a The disc 6 is a grinding drive device that rotates on its own and can rotate around the surface of the ball core 5 for grinding. The frame 2 and the spindle drive motor 4 are fixed on the base 1. One end of the positioning spindle 3 is installed on the frame 2, and the positioning spindle The other end of 3 is installed and connected with the mandrel drive motor 4, the ball core 5 is sleeved on the positioning mand...

Abstract

The invention relates to the technical field of ball core grinding, in particular to an efficient ball core grinding device. The efficient ball core grinding device comprises a base, a rack, a positioning mandrel, a mandrel driving motor, a ball core, a grinding disc and a grinding driving device, and the grinding driving device is used for driving the grinding disc to revolve and rotate around the surface of the ball core to conduct grinding. The rack and the mandrel driving motor are both fixed to the base. One end of the positioning mandrel is mounted on the rack, and the other end of the positioning mandrel is connected with the mandrel driving motor. The positioning mandrel is sleeved with the ball core. According to the efficient ball core grinding device, the grinding disc can rotate on the ball core, and moreover the grinding disc can revolve, so that the relative grinding speed of the grinding disc is increased, and accordingly the grinding efficiency is improved; through the arrangement of a swing shaft height adjusting device and a universal joint, uniform grinding pressure can be guaranteed while the grinding speed is increased, and the grinding disc is prevented from flying out when the rotating speed of the grinding disc is high and is made to adapt to changes of the surface of the ball core in the grinding process.

Description

technical field [0001] The invention relates to the technical field of ball core grinding, in particular to a ball core high-efficiency grinding device. Background technique [0002] In my country, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries, and occupy a pivotal position in the national economy. It has a 90-degree rotation action, The cock body is a sphere with a circular through hole or channel passing through its axis. The ball valve is sealed by the close contact between the valve seat and the ball core. During the rotation of the core, the contact surface between the surface of the ball core and the valve seat will be damaged, which will cause the ball valve to be closed tightly and cause leakage. Therefore, the ball core is a key part in the ball valve, and the machining accuracy of the roundness of the ball core dire...
