Description

Technical Field

[0001] The invention relates to an assembly posture adjustment mechanism for parts, in particular to an assembly posture adjustment mechanism for a spherical valve core. Background Art

[0002] A ball valve is a common pipeline valve, and its structure is mainly composed of a valve body, a valve cover, a valve seat, a spherical valve core, a valve stem and a handle. The spherical valve core is mainly assembled in the middle of the valve body, and is rotated by the handle through the valve stem to realize the opening and closing of the water hole in the spherical valve core, that is, to realize the opening and closing of the valve; therefore, the spherical valve core must be installed in the valve body at an accurate angle during assembly. However, during the assembly process, the ball valve cores are arranged in various postures in the material tray, which cannot meet the feeding posture of the automatic ball valve assembly machine. The traditional posture adjustment method mostly uses a vibration plate for vibration adjustment, that is, a large number of ball valve cores are stacked on the vibration plate, and then the principles of vibration and gravity are used to make each ball valve core in the correct assembly posture. This vibration adjustment method is prone to mutual collision between the ball valve cores, which will cause scratches and wear on the surface of the ball valve core, destroying the product quality, usually resulting in a finished product unqualified rate of about 2%, which requires manual repair or direct scrapping, causing great waste; moreover, the vibration process will also generate a lot of noise, forming noise pollution in the assembly workshop, and will also cause hearing damage to on-site staff.

[0004] The technical problem of the present invention is achieved through the following technical solutions:

[0005] A ball valve core assembly posture adjustment mechanism is used for quickly adjusting the assembly posture of a ball valve core with a water hole, comprising a frame, a discharge track installed on the frame and a manipulator clamp installed above the discharge track, one side of the discharge track is provided with a rotating block and a balance bar vertically fixed on the rotating block, and is also provided with a rotating component, a vibration component and a stripping component; the manipulator clamp clamps the ball valve core and is sleeved on the vertical balance bar through the water hole, the rotating component drives the rotating block to drive the balance bar in the vertical state to rotate to a horizontal state, and suspends the ball valve core in the discharge track, the vibration component drives the rotating block and the balance bar in the horizontal state to axially reciprocate and vibrate, and drives the ball valve core suspended on the balance bar to automatically adjust to the assembly posture, the stripping component drives the rotating block and the balance bar to radially translate, and drives the balance bar to separate from the water hole of the ball valve core, and the ball valve core automatically falls into the discharge track for output.

[0006] The rotating assembly drives the rotating block to drive the balance bar to rotate above the discharge track and be in a horizontal state, or drives the rotating block to drive the balance bar to rotate and reset to a vertical state; the stripping assembly drives the rotating block and the balance bar to radially reciprocate and translate away from the discharge track or close to the discharge track.

[0008] The frame is provided with a pushing assembly, which includes a reflective photoelectric device arranged at the starting end of the discharging track, a pushing cylinder arranged at the other side of the discharging track, a blocking plate arranged in the discharging track and driven by the pushing cylinder to reciprocate along the discharging track, and a straight vibration track connected to the terminal end of the discharging track; the spherical valve core automatically falls into the discharging track and is sensed by the reflected photoelectric device, and the pushing cylinder pushes the blocking plate to drive the spherical valve core that has fallen into the discharging track to translate along the discharging track into the straight vibration track, and then the straight vibration track actively outputs the ball.

[0009] The stripping assembly includes a stripping track and a stripping cylinder installed on the frame, and a stripping slide driven by the stripping cylinder to perform radial reciprocating translation; the vibration assembly includes a vibration track and a vibration cylinder installed on the stripping slide, and a vibration slide driven by the vibration cylinder to perform axial reciprocating translation vibration; the rotating assembly includes a rotating cylinder installed on the vibration slide, the rotating cylinder drives the rotating block to rotate, and the balance bar is vertically fixed on the rotating block.

[0010] A fixedly mounted arc strip is arranged above the rotating block, a guide groove is arranged in the arc strip, the end of the balance bar passes through the guide groove and is exposed, and the balance bar is driven by the rotating block to rotate forward and reversely by 90 degrees in the guide groove.

[0011] The water-through hole passes through along the diameter line of the spherical valve core, and a groove is arranged on the outer surface of the spherical valve core, and the axis center line of the groove is parallel to the axis center line of the water-through hole.

[0012] The vibration assembly drives the rotating block and the horizontal balance bar to axially reciprocate and translate and vibrate, and the ball valve core suspended on the balance bar automatically forms an assembly posture with the groove facing downward under the influence of gravity and inertia.

It even eliminates the noise pollution caused by the traditional vibration plate adjustment method, thereby better meeting the feeding posture of the automatic assembly ball valve machine.

[0023] A ball valve core assembly posture adjustment mechanism, such as Figure 1 , Figure 2 As shown, it belongs to the ball valve core feeding mechanism in the automatic ball valve assembly machine, which can be used to quickly adjust the assembly posture of the ball valve core 2 with the water hole 21 and the groove 22, so as to better meet the feeding posture of the automatic ball valve assembly machine.

[0024] The water hole 21 passes through along the diameter line of the spherical valve core 2 , and the groove 22 is arranged on the outer surface of the spherical valve core 2 , and the axis line of the groove 22 is parallel to the axis line of the water hole 21 .

[0025] The ball valve core assembly posture adjustment mechanism is mainly composed of a frame 1, a discharge track 3 installed on the frame, a manipulator gripper 4 installed above the discharge track, and a rotating block 5 installed on the frame 1 and located on one side of the discharge track 3, a rotating component 6, a vibration component 7 and a stripping component 8.

[0026] The frame 1 is a frame structure composed of a plurality of rods and plates assembled by bolts and nuts; the discharge track 3 is a linear track with a U-shaped cross-section, and the present invention uses the linear direction along the discharge track 3 as the axial translation direction of the entire mechanism, and the linear direction perpendicular to the discharge track 3 as the radial translation direction of the entire mechanism.

[0027] The discharge track 3, specifically the U-shaped inner bottom surface, is provided with a guide strip 31 extending axially, and the heights of the two track walls of the discharge track 3 are also designed to be different, and the side close to the rotating block 5 is a shorter track wall, and the side away from the rotating block 5 is a higher track wall, and the higher track wall is provided with an L-shaped groove 32.

[0028] The rotating assembly 6, the vibrating assembly 7 and the stripping assembly 8 are a combined structure composed of multiple groups of cylinders and carriages, specifically: the stripping assembly 8 includes a stripping track 81 fixedly mounted on the frame 1, a stripping carriage 83 movably mounted on the stripping track, and a stripping cylinder 82 mounted at the end of the stripping track, and the stripping carriage 83 is driven by the stripping cylinder 82 to make radial reciprocating translation along the stripping track 81; the vibrating assembly 7 includes a vibration track 71 fixedly mounted on the stripping carriage 83, a vibration carriage 73 movably mounted on the vibration track, and a vibration cylinder 72 mounted at the end of the vibration track, and the vibration carriage 73 is driven by the vibration cylinder 72 to make axial reciprocating translation vibration along the vibration track 71; the rotating assembly 6 includes a rotating cylinder 61 fixedly mounted on the vibration carriage 73, and the rotating cylinder drives the rotating block 5 to rotate.

[0029] At the same time, an arc-shaped bar 52 fixedly mounted on the rotating cylinder 61 and a guide groove 521 arranged in the arc-shaped bar are provided above the rotating block 5, and also includes a balance bar 51 vertically fixed on the rotating block 5, and the end of the balance bar passes through the guide groove 521 and is exposed; in this way, when the rotating cylinder 61 drives the rotating block 5 to rotate, the balance bar 51 can form a synchronous rotation, and due to the limitation of the guide groove 521, the balance bar 51 is driven by the rotating block 5 to only make 90-degree forward and reverse rotations in the guide groove 521, specifically: the rotating component 6 drives the rotating block 5 to drive the balance bar 51 to rotate forward to above the discharge track 3 and be in a horizontal state, or drives the rotating block 5 to drive the balance bar 51 to rotate in the opposite direction and reset to a vertical state.

[0030] Moreover, the rotation axis of the rotating block 5 is parallel to the axis of the discharging track 3, the axial reciprocating vibration axis of the rotating block 5 and the balance bar 51 is also parallel to the axis of the discharging track 3, the radial reciprocating axis of the rotating block 5 and the balance bar 51 is perpendicular to the axis of the discharging track 3, and the stripping assembly 8 drives the rotating block 5 and the balance bar 51 to move radially reciprocatingly away from the discharging track 3 or close to the discharging track 3.

[0031] When the rotating component 6 drives the rotating block 5 to drive the balance rod 51 to rotate forward to above the discharge track 3 and be in a horizontal state, the end of the balance rod 51 will enter the L-shaped groove 32 of the higher track wall, that is, first enter through the vertical groove of the L-shaped groove 32, and then be driven by the vibration component 7 to form axial reciprocating translation vibration in the horizontal groove of the L-shaped groove 32.

[0032] Therefore, the action process of the ball valve core assembly posture adjustment mechanism is as follows: first, a single ball valve core 2 is clamped by the manipulator claw 4 and is mounted on the vertical balance rod 51 through the water hole 21, and then the rotating block 5 is driven by the rotating assembly 6 to drive the vertical balance rod 51 to rotate 90 degrees along the guide groove 521 to the horizontal state, so that the ball valve core 2 can be suspended on the horizontal balance rod 51 and located in the discharge track 3, and then the vibration assembly 7 drives the rotating block 5 and the horizontal balance rod 51 to perform axial reciprocating translation vibration, and automatically adjusts the ball valve core 2 by using the gravity and inertia. To the correct assembly posture, specifically the assembly posture with the groove 22 of the ball valve core 2 facing downward. Generally, three reciprocating translational vibrations can drive the ball valve core 2 suspended on the balance bar 51 to automatically adjust to the assembly posture. Finally, the stripping component 8 drives the rotating block 5 and the balance bar 51 to radially translate away from the discharge track 3. Due to the obstruction of the shorter track wall of the discharge track, when driving the balance bar 51 to radially translate away from the discharge track 3, the balance bar 51 directly detaches from the water hole 21 of the ball valve core 2. At this time, the ball valve core 2 can automatically fall into the discharge track 3, and make the groove 22 just fit the fitting guide strip 31.

[0033] In addition, the frame 1 is also provided with a pushing assembly 9, which includes a reflective photoelectric device 91 arranged at the starting end of the discharge track 3, a pushing cylinder 92 arranged on the other side of the discharge track 3, a blocking plate 93 arranged in the discharge track 3 and driven by the pushing cylinder to reciprocate along the discharge track 3, and a straight vibration track 94 connected to the terminal end of the discharge track 3.

[0034] When the ball valve core 2 automatically falls into the discharge track 3 and is reflected by the photoelectric sensor 91, the push cylinder 92 will push the blocking piece 93 to drive the ball valve core 2 that falls into the discharge track 3 to be guided along the guide strip 31 of the discharge track 3 and translated into the straight vibration track 94. Since the straight vibration track 94 has its own active conveying components, the ball valve cores 2 that are pushed into the straight vibration track 94 in sequence by the blocking piece 93 can be actively output in sequence. Among them, the groove 22 of the ball valve core 2 just fits the guide strip 31, the purpose of which is to ensure that the ball valve core 2 is not easy to tip over during the process of being pushed and translated by the push component 9, and the stability is better.

[0035] During the above-mentioned action process, the manipulator gripper 4 grips the ball valve core 2, the rotating assembly 6 rotates the ball valve core 2, the vibrating assembly 7 vibrates the ball valve core 2, the stripping assembly 8 strips out the ball valve core 2, and the ball valve core 2 that falls into the discharging track 3 is pushed by the pushing assembly 9 to the straight vibration track 94. These five action processes are interconnected and cyclically performed. For example, when the manipulator gripper 4 grips the ball valve core 2 and is mounted on the vertical balance bar 51 through the water hole 21, so that the rotating assembly 6 drives the rotation and the ball valve core 2 is suspended on the horizontal balance bar 51, the manipulator gripper 4 simultaneously grips the next ball valve core 2. By analogy, other components all act according to this compact connection, thereby greatly improving the working efficiency of the entire mechanism. Moreover, after the action process of each component is completed, it is automatically reset to wait for the automatic adjustment and assembly posture of the next ball valve core 2.

[0036] Since the above-mentioned ball valve core 2 mainly utilizes the gravity and inertia of the ball valve core 2 to automatically adjust to the correct assembly posture during the process of adjusting the assembly posture, there will be no surface scratches and wear caused by mutual collision between each ball valve core 2 during the adjustment process, and there will be no risk of damaging the quality of the ball valve core 2. It even eliminates the noise pollution caused by the traditional vibration disk adjustment method, thereby better meeting the feeding posture of the automatic assembly ball valve machine.

[0037] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design similar to this embodiment should be included in the protection scope of the present invention.
