Ball refiner

Abstract

The invention relates to the technical field of valve ball manufacturing, in particular to a ball refiner. The ball refiner comprises a steering mechanism, a grinding mechanism, a mounting seat and a swinging mechanism, wherein a rotating seat is rotationally arranged on the mounting seat; the grinding mechanism is mounted on the rotating seat, and the grinding mechanism comprises grinding assemblies symmetrically arranged at two sides of the rotating base; each grinding assembly comprises a first power source, a first power head and a flexible clamping jaw; each flexible clamping jaw is connected with one first power source through one first power head; and a valve seat attached to a ball is arranged on each flexible clamping jaw, and grinding is conducted through contact between the valve seats and the ball. According to the grinding mechanism, the mode that the first power sources drive the corresponding flexible clamping jaws to move the corresponding valve seats is adopted to be matched with the ball to conduct grinding, in the whole process that the flexible clamping jaws are driven to move, when the clamped valve seats are in contact with the ball, resistance is borne, the flexible clamping jaws can move backwards, abrasion caused by hard collision between the valve seats and the ball is avoided, and rigid contact is converted into flexible contact, so that the service life of a workpiece is prolonged.

Description

technical field [0001] The invention relates to the technical field of valve ball manufacturing, in particular to a ball refiner. Background technique [0002] In order to make the ball valve meet the corresponding sealing performance requirements, it is usually necessary to grind the ball of the ball valve. [0003] For example, the Chinese Utility Model Patent No. CN201720795551.0 discloses an automatic sphere grinding machine, which includes a steering mechanism for fixing the sphere, a swing mechanism for driving the steering mechanism to reciprocate in the horizontal direction, and a grinding head mechanism for grinding the sphere. The mechanism and the steering mechanism are arranged in a staggered manner, and the swing mechanism is connected to the longitudinal track plate to drive the longitudinal track plate to swing back and forth around the rotating shaft seat, so that the clamping grinding head can grind the sphere at different angles.

Problems solved by technology

[0004] In the actual working process, since the steering mechanism, ball, tailstock and other components are installed on the longitudinal track plate, because these components are relatively heavy, not only the motor needs a large operating power, but also the movement of the longitudinal track plate is relatively cumbersome , resulting in low machining accuracy, so the device needs to be further improved; at the same time, the jaws of the grinding head mechanism are in rigid contact, which is prone to workpiece collisions and wear.
