This invention discloses a valve core ball grinding processing device for ball valves, specifically relating to the field of grinding technology. It includes a support platform, a housing disposed on the upper part of the support platform, a material handling structure on the top wall of the inner cavity of the housing, and a valve core grinding structure on the bottom wall of the inner cavity. This invention utilizes the driving action of a material handling drive to grip a material handling follower and feed it into a grinding component. A rack drives the grinding component to rotate repeatedly, during which the valve core ball is fixed by a valve core limiting component, thereby achieving the grinding of the valve core ball. After grinding, the material handling drive and follower remove the valve core ball from the grinding component and feed it into a discharge hopper on the rear side. Simultaneously, a new valve core ball is fed from the material handling tray into the grinding component, achieving continuous processing, reducing contact between operators and the valve core ball, grinding fluid, and grinding equipment, and reducing the occurrence of safety accidents.

This invention discloses a main start valve maintenance fixture and method, belonging to the field of maintenance fixture technology. It includes a sleeve, one end of which is used to fix a valve stem nut, and the other end is fitted with a stud head. A lever is fixed perpendicularly to the sleeve axis at the end of the sleeve near the stud head. A threaded hole is formed at a set distance between the sleeve and the lever, allowing a connecting piece to pass through and fix the valve stem. The lever is rotated to remove the nut, or the stud head can be used with a pneumatic or electric wrench to grind the valve core. This invention enables both valve stem replacement and valve core grinding of the main start valve, allowing for maintenance based on the damage condition of the main start valve, increasing applicability and reducing costs.

This invention discloses a glass substrate grinding device, relating to the field of material processing technology. It includes a base and a grinding disc. A robotic arm is mounted on the top of the base. The outer periphery of the grinding disc is covered with V-shaped grinding grooves. It includes a connecting ball, one end of which is connected to a rotating rod. The rotating rod is rotatably connected to the side wall of the base via a ball-shaft. An installation port is provided on the connecting ball. In this invention, the grinding disc is connected to a connecting frame and a rotating shaft. The robotic arm drives a switching mechanism to move these components. The outer periphery of the grinding disc has V-shaped grinding grooves pointing in the same direction. During rotation, the glass substrate is ground, and debris is ejected from the grinding grooves under centrifugal force. The grinding disc rotates towards the grinding grooves. When the left-right movement direction changes, the robotic arm pulls an elastic coil, which in turn pulls the rotating shaft and causes the grinding disc to rotate, so that the tips of the grinding grooves face the direction of movement, thereby achieving grinding and finishing of the glass substrate.
