SUMMARY
[0003] In view of the above, in order to overcome the defects of the prior art, the utility model provides a bearing bolt guide alignment vibrating disc.
[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a bearing bolt guide alignment vibrating disc, including the base, the base upper end is provided with the hopper, the base is provided with the drive mechanism for driving the hopper torsional swing vibration, the hopper is equipped with the material collecting cavity for workpiece storage, the hopper is equipped with the vibration spiral groove, the discharge plate, the guide rail assembly and the discharge rail, the discharge plate is arranged on the upper end of the hopper, the vibration spiral groove is arranged in spiral ascending, the lower end of the vibration spiral groove is communicated with the material collecting cavity, and the upper end is connected with the discharge plate, the upper end of the guide rail assembly is arranged below the discharge plate, the lower end of the guide rail assembly is communicated with the discharge rail, the guide rail assembly includes the receiving rail for receiving the discharge plate and the shunt guide rail for moving the workpiece in the vertical state on the receiving rail to the discharge guide rail, the receiving rail includes the inner side guide rail and the outer side guide rail arranged at the same height, the spacing between the inner side guide rail and the outer side guide rail is greater than the diameter of the workpiece screw embryo and less than the diameter of the workpiece cylindrical head, the shunt guide rail includes the inner guide rail and the outer guide rail arranged staggered in height, the inner guide rail is connected with the inner side guide rail, the bottom surface of the outer guide rail is higher than the top surface of the outer side guide rail, and the outer guide rail is arranged outside the outer side guide rail, a gap is arranged between the outer guide rail and the inner guide rail for the workpiece in the horizontal state to fall vertically along the shunt guide rail, and the discharge guide rail is provided with the top for the workpiece in the vertical state to lie down and enter the discharge guide rail.
[0005] By adopting the above technical scheme, since the weight of the cylindrical head is greater than the weight of the screw blank, the center of gravity of the workpiece is close to the cylindrical head, the receiving track utilizes the size relationship of the cylindrical head diameter > the spacing > the screw blank diameter, realizes "receiving arrangement", regardless of the workpiece on the discharge plate in the horizontal forward (i.e. the cylindrical head towards the moving direction), the horizontal backward (i.e. the screw blank towards the moving direction) or the horizontal vertical state (i.e. the workpiece in the flat lying state and the cylindrical head towards the vertical direction of the moving direction), when it falls on the receiving track, the center of gravity of the workpiece is changed under the influence of the receiving track, the workpiece state is changed to the vertical state of the screw blank downward or the horizontal state of the cylindrical head forward or backward, which ensures that the workpiece stably enters the next link; the shunt guide rail forms a slope and a gap due to the height difference between the inner guide rail and the outer guide rail, realizes "shunt screening", the workpiece in the horizontal state will fall from the gap, and the workpiece in the vertical state and the screw blank downward is allowed to pass, which ensures that the workpiece posture entering the next link is consistent; since the weight of the cylindrical head is greater than the weight of the screw blank, the center of gravity of the workpiece is located in the cylindrical head, when the workpiece in the vertical state of the screw blank downward moves forward to the top and touches the screw blank, due to the change of the center of gravity, the workpiece naturally falls forward into the discharge guide rail; through the two-stage processing mechanism of "receiving arrangement" + "shunt screening and posture conversion", almost 100% correct orientation can be realized, which ensures the continuity and stability of subsequent automatic production; the seamless automatic grinding machine realizes uninterrupted feeding, complete automation and greatly improves the efficiency; the whole device is integrated on the vibration disc, without additional complex mechanical hands or visual systems, can be adjusted by fine-tuning the position of the outer guide rail and the outer guide rail, can adapt to bearing bolts in different size ranges, and has wide adaptability; all functions are realized by mechanical structures, the structure is simple, maintenance is convenient, and the cost is low.
[0006] The utility model further sets up: the lateral width of the gap is less than the diameter of workpiece cylindrical head, the spacing between the bottom surface of outer guide rail and the top surface of inner guide rail is greater than or equal to the diameter of workpiece cylindrical head, the height difference between the bottom surface of outer guide rail and the top surface of inner guide rail is less than the height of workpiece cylinder.
[0007] By adopting the above technical solution, the diversion guide rail, due to the height difference between the inner and outer guide rails, forms a slope and gap to achieve "diversion and screening". Workpieces in a transverse state, initially balanced by the support of the inner and outer guide rails, slide along the support track rather than roll (the outer circumference of the cylindrical head contacts the inner and outer guide rail lines). Before entering the diversion guide rail, because "the distance between the bottom surface of the outer guide rail and the top surface of the inner guide rail is greater than or equal to the diameter of the workpiece's cylindrical head", and the diameter of the transverse workpiece is less than the maximum gap, it will fall through the gap; the screw blank faces downwards. For a vertically positioned workpiece with its cylindrical head facing upwards (i.e., the bottom of the original cylindrical head is in contact with the inner and outer guide rails respectively), when it enters the diversion guide rail, because "the lateral width of the gap is less than the diameter of the workpiece's cylindrical head" and "the height difference between the bottom surface of the outer guide rail and the top surface of the inner guide rail is less than the height of the workpiece's cylinder," the inner side of its cylindrical head is mounted above the inner guide rail, while the outer side is limited by the outer guide rail, ensuring the stability of the workpiece's movement. Furthermore, only vertically positioned workpieces with the screw blank facing downwards are allowed to pass through, ensuring that the posture of the workpieces entering the next stage is consistent.
[0008] The present invention further comprises: the guide rail assembly and the discharge rail are both located outside the collection chamber; the hopper is provided below the guide rail assembly and the discharge rail for receiving workpieces falling from the guide rail assembly and the discharge rail; one end of the discharge rail of the discharge chamber is the discharge end; the discharge end is provided with a discharge port connected to the collection chamber; one end of the discharge plate of the discharge chamber is the discharge end; the bottom wall height of the discharge end is higher than that of the discharge end; and the bottom wall height of the discharge end is higher than that of the collection chamber.
[0009] By adopting the above technical solution, the guide rail and discharge rail are located outside the collection chamber, separating the two functional areas of spiral feeding and guiding sorting. The external rail environment is stable and not affected by the rolling of materials in the hopper. Moreover, its location on the outside facilitates debugging, cleaning, and adjustment. The return chamber establishes a "dedicated return channel" for unqualified workpieces. Falling workpieces will not crash into the vibrating spiral groove, avoiding unstable feeding and damage to parts caused by "crashing". At the same time, it prevents workpiece blockage and accumulation, which would affect the stable operation of the rail. The bottom wall height of the discharge section is greater than that of the return end, forming a natural slope towards the return port in the return chamber. The bottom wall height of the return end is greater than that of the collection chamber. Once the workpiece falls into the return chamber, it can automatically and smoothly slide towards the return port by gravity without any additional power. This is convenient and reliable. Side flow reduces impact and interference to the workpieces at the bottom. Automatic return reduces labor costs and improves feeding efficiency.
[0010] The present invention further comprises: one end of the discharge plate corresponding to the receiving track is a dropping section, the inner side of the dropping section is higher than the outer side, one end of the receiving track corresponding to the discharge plate is located below the dropping section, and the dropping section is provided with a movable component for driving the workpieces piled on the discharge plate into the receiving track. The movable component includes an inverted L-shaped bracket located on the outer side of the discharge plate and a swinging component located above the dropping section. The swinging component includes a hinged part that is movably hinged to the bracket and a swinging part that swings with the axis of the hinged part as the axis of the hopper torsion vibration. The swinging trajectory of the swinging part is located between the outer guide rail and the inner guide rail.
[0011] By adopting the above technical solution, the receiving track is set below the "outer side" of the unloading section. Due to torsional vibration and gravity, the ramp naturally guides the workpiece to move and gather towards the lower "outer side." When the workpiece on the unloading section rolls or vibrates and falls down with the swinging component, it will land on the receiving track, improving the success rate and directional accuracy of the transition of the workpiece from the discharge plate to the receiving track. The swinging component is suspended by a hinge, and its swinging is entirely based on the torsional vibration energy of the hopper itself, without the need for any additional motor, cylinder, or control system. The structure is simple and energy-saving. The swinging trajectory of the swinging component covers the area directly above the entrance of the receiving track. When the workpiece is located in the unloading section with its side facing forward or backward, the swinging component inserts into the inner wall of the workpiece and then moves the workpiece upward towards the receiving track during the swinging process. When the workpiece falls in the correct position (vertical, with the screw blank facing down), the screw blank of the workpiece will fall into the gap between the inner and outer guide rails, and the cylindrical head will rest on the inner and outer guide rails. At this point, the swinging part will not contact the workpiece during its return stroke. The workpiece moves along the receiving track. When the workpiece falls vertically with the screw blank facing upwards, the swinging part contacts the screw blank of the workpiece, causing the workpiece's center of gravity to change. The workpiece will then rotate 180 degrees to the correct position and move along the receiving track. When the workpiece is in a horizontally vertical position at the unloading section, the swinging part contacts the outer circumference of its cylindrical head, causing it to roll forward to the top of the receiving track. Its falling state may be vertical or horizontal. When it falls vertically, the same principle applies. When the workpiece falls horizontally forward onto the receiving track, it moves along the receiving track and is screened by the diversion guide. When the workpiece continues to roll horizontally vertically, it rolls directly from the receiving track into the return chamber below. The swinging part provides preliminary guidance and sorting for the workpiece before it enters the diversion guide, improving the accuracy and efficiency of diversion. It also plays a guiding role, increasing the probability of the workpiece entering the receiving track and improving stability.
[0012] The present invention further includes: a positioning nut for positioning the hinge part on the bracket, the positioning nut being respectively located on the inner and outer sides of the hinge part; the swinging part including an L-shaped connecting section and a hook section, the two ends of the connecting section being connected to the hinge part and the hook section respectively; the diameter of the hook section being smaller than the inner diameter of the workpiece; when the workpiece is located in the unloading part and is arranged in the same direction as the hook section, the hook section swings and inserts into the inner cavity of the workpiece and drives the workpiece to fall onto the receiving track; when the workpiece is located in the unloading part and is set at an angle with the hook section, the hook section impacts the outer circumference of the workpiece, causing it to roll towards the receiving track.
[0013] By adopting the above technical solution, the position of the hinge can be precisely and subtly adjusted back and forth by tightening the positioning nuts on both sides, changing the relative position of the rotation center of the swinging part. This allows for the calibration of the swinging trajectory and stationary position of the swinging part (especially the hook segment), ensuring that the hook segment can accurately insert into the inner cavity of the workpiece or impact the correct position. Vibration environments can easily loosen threaded connections. The nuts on both the inner and outer sides form a "locking structure," which effectively prevents the hinge from shifting during long-term vibration, providing bidirectional locking, preventing loosening, and maintaining the stability of the equipment. When handling bearing bolts of different sizes and specifications, it may be necessary to fine-tune the initial position of the swinging part. This design facilitates adjustment, is linear, and can be fixed, enhancing the versatility and adaptability of the equipment. The hook segment drives the workpiece to move, ensuring that it falls accurately and smoothly into the receiving track below, achieving "assisted guidance feeding" and avoiding inaccurate landing. At the same time, the impact force of the hook segment generates a tangential component, causing the workpiece to roll towards the receiving track, which may correct its posture to vertical or at least remove it from a potentially blocked position, promoting material flow and preventing blockage.
