the universal ball is mainly used for applying a fulcrum for front-rear auxiliary limiting rotation to the ball body when the ball body rotates;
it should be noted that the radius of the circle formed by using the axes of the universal ball and the ball passage as the center of the circle is larger than the radius of the circle formed by attaching the inner side annular wall of the shaft sleeve, that is, after the initial compression of the attached shaft sleeve, the inner side annular wall and the universal ball are positioned on the same circle side and are consistent with the inner diameter of the ball body.
In the specific implementation, a sphere is sucked into a collecting pipe through the air draft of a fan and falls into a storage box, then a cut-off board is opened, the drainage sphere enters a collecting hopper, the exhaust pipe draws air at a constant speed to drive the sphere to enter a sphere channel and sequentially pass through a first group of clamping and supporting devices, resistance is applied to a sphere shell by a right supporting board in each clamping device, hardness monitoring is carried out, a roller on the outermost side is in a self-locking state, the roller on the outermost side rolls to the clamping and supporting device which does not clamp and support the sphere on the rightmost side, after a sensing sleeve in each clamping assembly monitors that the sphere is attached to the clamping and supporting device, the attachment sensing sleeve is temporarily attached or continuously triggered by a small amplitude, the attachment sensing sleeve is fed back to the middle left control unit to trigger and start a push-pull rod in the middle left clamping assembly to extend, so that the sphere is clamped on a supporting rod in the left clamping assembly, and simultaneously the middle left control unit feeds back to start the right control unit in the left clamping and supporting device, regulating and controlling the right supporting rod to rotate upwards, waiting for the next ball to enter, repeating the ball entering and clamping steps, starting a monitoring component in the clamping device after the clamping is finished, pushing a push-pull rod II to push a joint shaft sleeve to press the outer wall of the ball until the universal ball touches the outer wall of the ball, stopping extending, monitoring the touch state of the universal ball with the ball again by using joint sensing sleeves outside a left roller and a right roller, enabling the center of the ball and the center of the upper end of the monitoring component to coincide with the axis of a ball channel, enabling a left air injection pipe to inject air inwards, enabling a right air injection pipe to exhaust air outwards, enabling the ball to spin, further judging the concave-convex condition of the ball shell, marking the ball by using a control element, and reducing the inclination angle of the corresponding supporting rod through the first corresponding push-pull rod when the ball does not reach or smoothly passes through the standard minimum value of the pressure intensity of the first group of clamping devices, the spheroid is promoted to pass through, avoids the spheroid damaged, produces the jam to record the intensity value of exerting pressure when passing through time die-pin, accomplish the collection back, the die-pin is flat in proper order soon in the press from both sides the die-pin device of rethread collection car top, and the jet-propelled pipe jet-propelled makes the spheroid roll into and serves in the device and serve.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the inventive concept within the technical scope of the present invention, and the technical solution and the inventive concept thereof should be covered by the scope of the present invention.
