The ball valve core assembling posture adjusting mechanism is mainly composed of a rack 1, a discharging rail 3 arranged on the rack, a manipulator clamping jaw 4 arranged above the discharging rail, a rotating block 5 arranged on the rack 1 and positioned on one side of the discharging rail 3, a rotating assembly 6, a vibrating assembly 7, a stripping assembly 8 and the like.

The frame 1 is a frame structure formed by assembling and combining a plurality of rod pieces and plates through bolts and nuts; the discharging rail 3 is a linear rail with a U-shaped cross section, and the linear direction along the discharging rail 3 is taken as the axial translation direction of the whole mechanism, and the linear direction perpendicular to the discharging rail 3 is taken as the radial translation direction of the whole mechanism.

In the ejection of compact track 3, specifically the bottom surface is equipped with a guide strip 31 along axial extension in the U type, ejection of compact track 3's two track wall height also designs into different, and is close to 5 one sides of rotatory piece for shorter track wall, keeps away from rotatory piece 5 for higher track wall, is equipped with L type groove 32 on this higher track wall.

The rotating assembly 6, the vibrating assembly 7 and the stripping assembly 8 are combined structures which are jointly composed of a plurality of groups of cylinders and plankers, and specifically comprise the following components: the stripping assembly 8 comprises a stripping rail 81 fixedly arranged on the frame 1, a stripping planker 83 movably arranged on the stripping rail and a stripping cylinder 82 arranged at the end part of the stripping rail, wherein the stripping planker 83 is driven by the stripping cylinder 82 to do reciprocating translation along the radial direction of the stripping rail 81; the vibration assembly 7 comprises a vibration rail 71 fixedly arranged on the stripping planker 83, a vibration planker 73 movably arranged on the vibration rail and a vibration cylinder 72 arranged at the tail end of the vibration rail, and the vibration planker 73 is driven by the vibration cylinder 72 to do axial reciprocating translational vibration along the vibration rail 71; the rotating assembly 6 comprises a rotating cylinder 61 fixedly mounted on the vibrating carriage 73, and the rotating cylinder drives the rotating block 5 to rotate.

Meanwhile, an arc-shaped bar 52 fixedly installed on the rotary cylinder 61 and a guide groove 521 arranged in the arc-shaped bar are arranged above the rotary block 5, the balance bar 51 vertically fixed on the rotary block 5 is further included, and the tail end of the balance bar is exposed through the guide groove 521; thus, when the rotating cylinder 61 drives the rotating block 5 to rotate, the balance bar 51 can form synchronous rotation, and due to the limitation of the guide groove 521, the balance bar 51 can only make 90-degree positive and negative rotation in the guide groove 521 by the rotating block 5, specifically: the rotating assembly 6 drives the rotating block 5 to drive the balancing rod 51 to rotate forward to the upper part of the discharging track 3 and be in a horizontal state or drives the rotating block 5 to drive the balancing rod 51 to rotate reversely and reset to a vertical state.

When the ball valve core 2 automatically drops into the discharging track 3 and is induced by the reflected photoelectric sensing 91, the pushing cylinder 92 will push the blocking sheet 93 to drive the ball valve core 2 dropping into the discharging track 3 to be guided along the guide strip 31 of the discharging track 3 and to be translated into the straight vibrating track 94, and since the straight vibrating track 94 is provided with an active conveying part, the ball valve cores 2 pushed into the straight vibrating track 94 by the blocking sheet 93 in sequence can be output in sequence actively. Wherein, the groove 22 of the ball valve core 2 just fits the guide strip 31, and its purpose is to ensure that the ball valve core 2 is not easy to topple over and has better stability in the process of being pushed by the pushing component 9 to move horizontally.

In the above-mentioned action process, the spheroid case 2 is got to manipulator clamping jaw 4 clamp, 6 revolving ball case 2 of rotating assembly, 7 oscillating ball case 2 of vibrating assembly, take off that material assembly 8 deviates from spheroid case 2 and drop spheroid case 2 in ejection of compact track 3 and promote these five action processes all to link up the circulation and go on each other in straight shake track 94 by pushing assembly 9, for example manipulator clamping jaw 4 presss from both sides and gets spheroid case 2 and through water hole 21 suit on vertical balancing pole 51, when making spheroid case 2 hang on the balancing pole 51 of horizontality for 6 drive rotations of rotating assembly, manipulator 4 carries out the clamp of next spheroid case 2 again simultaneously, analogize to this and all move according to this kind of compactness linking up to other subassemblies, thereby greatly improved the work efficiency of whole mechanism. And after the action process of each component is finished, the components are automatically reset to be automatically adjusted and assembled in the posture of the next ball valve core 2.

Because above-mentioned spheroid case 2 is in the in-process of adjustment equipment gesture, mainly utilized the gravity and the inertia influence that spheroid case 2 received and automatically regulated to correct equipment gesture, so all can not have the surface scratch wearing and tearing condition that collides each other and leads to between every spheroid case 2 in this adjustment process, just also can not appear destroying the risk of spheroid case 2 quality, the noise pollution who has also eliminated the mode that adopts traditional vibration dish to adjust the gesture even to better satisfy the feed gesture of automatic assembly ball valve machine.
