[0038] A cylinder is fixed at the bottom of the push plate 201b. By placing the bolts to be processed in the storage box 201a, the cylinder is started to drive the push plate 201b to move. The push plate 201b is set to an inclined surface, and the bolts are pushed into the sliding frame 201c by the push plate 201b. At this time, the bolts will slide in the sliding frame 201c and be transmitted to the transmission bin 201e. When a bolt moves vertically, the vertically moving bolts can be guided back into the storage box 201a through the setting of the arc panel 201d, and the horizontal bolts will move into the transmission bin 201e. The height of the transmission bin 201e can only accommodate horizontal bolts, and vertical bolts will not enter the transmission bin 201e. The bolts can be moved into the discharge pipe 201f through the guidance of the transmission bin 201e. 1f is provided with an inclined stopper at the top, which can prevent the bolt from flipping to a vertical direction when the bolt moves into the discharge tube 201f. There are two baffle plates 201g, which are both plugged into one side of the discharge tube 201f. One side of the two baffle plates 201g is provided with a notch, and the two notches are set to be staggered. A motor is provided at the bottom of the baffle plate 201g, which is driven by the motor to rotate the baffle plate 201g. When the notch on the baffle plate 201g is separated from the discharge tube 201f, the bolt can fall to the top of the placement table 301a. The top of the placement table 301a is set as an arc surface, and the distance between the discharge tube 201f and the top of the placement table 301a is relatively close, so that the bolt can fall flat onto the placement table 301a, and the bolt can be slowly dropped by driving the baffle plate 201g to rotate slowly by the motor.

[0039] The placement component 300 is arranged at the bottom of the feeding tube 201f, and includes a placement table 301a, a rotating table 301b, a push rod 301c, a rotating rod 301d, a movable rod 301e, a first torsion spring 301f and a guide table 301g. The placement table 301a is arranged below the feeding tube 201f, the rotating table 301b is fixed at the bottom of the placement table 301a, the push rod 301c is arranged below the placement table 301a, the rotating rod 301d is fixed to one end of the push rod 301c, the rotating rod 301d is inserted into one side of the placement table 301a, the rotating rod 301d is rotatably connected to the placement table 301a through a rotating shaft, the movable rod 301e is fixed to one end of the rotating rod 301d, one end of the first torsion spring 301f is fixed to one side of the rotating rod 301d, and the other end is fixed to the inner wall of the placement table 301a, and the guide table 301g is located on one side of the movable rod 301e.

[0040] There are three placement platforms 301a, all of which are arranged below the feeding tube 201f. A movable groove is provided on the placement platform 301a, and a push rod 301c slides in the movable groove. One end of the movable groove is provided with an inclined surface. There are two push rods 301c, all of which are arranged below the placement platform 301a. One of the push rods 301c and the movable groove is provided with an inclined surface corresponding to the inclined surface. There are two guide platforms 301g, all of which are arranged on one side of the movable rod 301e. A guide groove is provided on one side of the guide platform 301g, and the movable rod 301e slides in the guide groove. When the screw After the bolt moves to the top of the placement table 301a, the rotation of the rotating table 301b can drive the placement table 301a to rotate. When the placement table 301a is rotated to the bottom of the tapping machine 101, the guide groove set on one side of the guide table 301g can guide the movable rod 301e to move the movable rod 301e. The movement of the movable rod 301e will drive the rotating rod 301d to rotate. The rotation of the rotating rod 301d will drive the push rod 301c to move. When the rotating rod 301d rotates, a torsional force can be applied to the first torsion spring 301f.

After the bolt is tapped, the rotation of the rotating platform 301b will drive the placement platform 301a to rotate until it is separated from the guide platform 301g. At this time, the guide groove will release the squeezing of the movable rod 301e, and then the movable rod 301e will be driven by the rotation force of the first torsion spring 301f. 01e returns to its original position, and when the placement table 301a is rotated to contact with another guide table 301g, the guide groove arranged on the other guide table 301g is in the reverse direction, which will drive the movable rod 301e to move in the reverse direction, and then drive the push rod 301c to move in the reverse direction, so that the bolt can be pushed off the placement table 301a, and a leakage groove is arranged on the rotating table 301b. At this time, the bolt will fall into the leakage groove, and then be guided by the unloading bin arranged on the other guide table 301g, so as to complete the unloading of the bolt, and the unloading bin is arranged at the bottom of the leakage groove.

[0041] Example 2

[0042] Reference Figure 2 to Figure 13 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, a first guide plate 202a is fixed in the material storage box 201a, a second guide plate 202b is fixed on one side of the sliding frame 201c, a vibration plate 202c is arranged in the sliding frame 201c, and one end of the vibration plate 202c is hinged to the sliding frame 201c.

[0044] There are two first guide plates 202a, both of which are set as inclined surfaces. The two first guide plates 202a can guide the bolts in the storage box 201a to the top of the push plate 201b. The second guide plate 202b is set as an inclined surface. When the bolts are moved to one side of the sliding frame 201c by the push plate 201b, the bolts can be moved into the sliding frame 201c by the second guide plate 202b. A positioning plate is fixed on the top of the sliding frame 201c. The positioning plate can be set to block the bolts in the sliding frame 201c to prevent the bolts in the sliding frame 201c from falling. The vibration plate 202c can vibrate the vertical bolts in the sliding frame 201c to a plane, thereby increasing the number of flat bolts.

[0045] Specifically, a vibration block 202d is fixed at one end of the vibration plate 202c, a centrifugal column 202e is arranged in the vibration block 202d, a moving bar 202f is fixed at the bottom of the vibration block 202d, the moving bar 202f is plugged into the bottom of the sliding frame 201c, the moving bar 202f and the sliding frame 201c are movably connected, a first spring 202g is fixed at the bottom of the vibration block 202d, and the first spring 202g is fixed to the inner wall of the sliding frame 201c.

[0046] A leakage hole is provided in the vibration block 202d, and the centrifugal column 202e slides in the leakage hole. The radius of the leakage hole is small. The centrifugal column 202e rotates in the leakage hole to make the vibration block 202d vibrate, thereby driving the vibration plate 202c to vibrate. Since the radius of the leakage hole is small, the vibration amplitude of the vibration block 202d is small, preventing the horizontal bolts from being converted to vertical by the vibration of the vibration plate 202c. When the vibration block 202d moves, it can drive the moving bar 202f to move. The movement of the moving bar 202f can support the vibration block 202d to prevent the vibration block 202d from deviating during movement. When the vibration block 202d moves, it can apply a squeezing force to the first spring 202g. The rebound force of the first spring 202g will drive the vibration block 202d to return to its original position, thereby increasing the smoothness of the movement of the vibration block 202d.

[0047] Specifically, a turntable 202h is fixed on one side of the centrifugal column 202e, a support shaft 202i is fixed on one side of the turntable 202h, a positioning block 202j is provided on one side of the support shaft 202i, the positioning block 202j is rotatably connected to the support shaft 202i through a rotating shaft, and a second torsion spring 202k is fixed on one side of the positioning block 202j.

[0048] The rotation of the turntable 202h will drive the centrifugal column 202e to rotate. The centrifugal column 202e is fixed at a position eccentric to the center of one side of the turntable 202h, so that when the turntable 202h rotates, the centrifugal column 202e is driven to rotate centrifugally. The support shaft 202i is used to support the turntable 202h. The positioning block 202j is fixed to one side of the material storage box 201a. The support shaft 202i can be supported by the setting of the positioning block 202j. The movement of the push plate 201b can drive the turntable 202h to rotate. When the turntable 202h rotates, a torsional force can be applied to the second torsion spring 202k. The rotation force of the second torsion spring 202k can drive the turntable 202h to rotate. The forward or reverse rotation of the turntable 202h can drive the vibration block 202d to move.

[0049] Specifically, a pull rope 2021 is fixed to one side of the turntable 202h, a connecting plate 202m is fixed to the bottom of the pull rope 2021, the connecting plate 202m is fixed to one side of the push plate 201b, the connecting plate 202m is plugged into one side of the material storage box 201a, and the connecting plate 202m and the material storage box 201a are movably connected.

[0050] When the push plate 201b moves, the connecting plate 202m can be driven to move, and the movement of the connecting plate 202m can drive the pull rope 202l to move, and the movement of the pull rope 202l can drive the turntable 202h to rotate. When the turntable 202h rotates, it can apply a torsional force to the second torsion spring 202k. When the push plate 201b rises, the pulling of the pull rope 202l can be released. At this time, the turning plate 202h can be driven to reverse by the force of the rotation of the second torsion spring 202k. At the same time, the pull rope 202l can also be reeled in. A protective cover is sleeved on the outside of the turntable 202h, the protective cover is fixed to one side of the sliding frame 201c, the second torsion spring 202k is fixed to one side of the protective cover, the protective cover is sleeved on the outside of the support shaft 202i, the protective cover is movably connected to the support shaft 202i, the protective cover is sleeved on the outside of the pull rope 202l, the pull rope 202l is movably connected to the protective cover, and the turntable 202h can be protected by the setting of the protective cover.

[0051] Specifically, a rotating column 302a is fixed at the bottom of the rotating table 301b, a gear 302b is sleeved on the outer side of the rotating column 302a, a driving wheel 302c is arranged on one side of the gear 302b, the gear 302b and the driving wheel 302c are meshed, three sets of teeth are arranged on one side of the driving wheel 302c, the driving wheel 302c is meshed with the gear 302b, and when the teeth on the driving wheel 302c rotate to contact with the gear 302b, the gear 302b can be rotated one hundred and twenty degrees.

[0052] The rotation of the gear 302b drives the rotating column 302a to rotate, and the rotation of the rotating column 302a drives the rotating platform 301b to rotate, so that the placing platform 301a can be moved to a designated position.

[0053] Example 3

[0054] Reference Figures 1 to 13 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0055] Specifically, a pulley 302d is fixed to the bottom of the driving wheel 302c, and a belt 302e is sleeved on the outer side of the pulley 302d.

[0056] The rotation of the belt 302e drives the pulley 302d to rotate, and the rotation of the pulley 302d drives the driving wheel 302c to rotate.

[0057] Specifically, a tooth frame 302f is provided in the belt 302e, and a movable disk 302g is provided in the tooth frame 302f. The movable disk 302g and the tooth frame 302f are rotatably connected through a bearing. A ramp block 302h is provided on the top of the movable disk 302g. The ramp block 302h and the top of the movable disk 302g are slidably connected. A second spring 302i is fixed on one side of the ramp block 302h, and the second spring 302i is fixed to the top of the movable disk 302g.

[0058] An inclined tooth groove is provided in the tooth frame 302f. When the push plate 201b rises to push the bolt, the push plate 201b will drive the movable disk 302g to rotate. The tooth frame 302f is rotatably connected to the top of the base 102 through a rotating shaft. The rotation of the movable disk 302g will drive the inclined surface block 302h to squeeze the inclined surface tooth groove. When squeezing the inclined surface tooth groove, the inclined surface block 302h can be moved, thereby applying an extrusion force to the second spring 302i. When the inclined surface tooth groove moves to separate from the inclined surface block 302h, the rebound force of the second spring 302i can make the inclined surface block 302h return to its original position. At this time, the tooth frame 302f will not be driven to rotate. When the push plate 201b descends, the movable disk 302g will be driven to reverse. At this time, the inclined surface tooth groove will squeeze the inclined surface block 302h, thereby driving the tooth frame 302f to rotate, and the rotation of the tooth frame 302f can drive the belt 302e to rotate.

[0059] Specifically, a driving column 302j is fixed on the top of the movable disk 302g, a moving ring 302k is sleeved on the outer side of the driving column 302j, the driving column 302j and the moving ring 302k are movably connected, and the moving ring 302k is fixed to the bottom of the push plate 201b.

[0060] A driving groove is provided on the surface of the driving column 302j, and a driving bar is provided in the movable ring 302k. The driving bar slides in the driving groove. When the push plate 201b moves, the movable ring 302k is driven to move. The movable ring 302k moves on the driving column 302j, thereby driving the driving column 302j to rotate. The rotation of the driving column 302j can drive the movable disk 302g to rotate.

[0061] Specifically, it also includes a tapping assembly 100, which is arranged above the placement table 301a, including a tapping machine 101, a base 102 and a workbench 103. The tapping machine 101 is arranged above the placement table 301a, the base 102 is fixed to the bottom of the tapping machine 101, and the workbench 103 is fixed to the bottom of the base 102.

[0062] The tapping machine 101 can be used to punch holes in bolts to form threads inside them. The base 102 is used to support the tapping machine 101. The workbench 103 can provide a platform for bolt processing to ensure the accuracy and reliability of the processing process.

[0063] When in use, the bolts are poured into the storage box 201a, and then the cylinder is started to drive the push plate 201b to move, and the push plate 201b pushes the bolts into the sliding frame 201c. At this time, the bolts will slide in the sliding frame 201c and be transmitted to the transmission bin 201e. When the push plate 201b pushes the bolts into the sliding frame 201c, it will drive the connecting plate 202m to move. The movement of the connecting plate 202m can release the pulling of the pull rope 202l, and then the rotation force of the second torsion spring 202k can drive The turntable 202h rotates, and the rotation of the turntable 202h drives the centrifugal column 202e to rotate. The rotation of the centrifugal column 202e in the leakage hole can make the vibration block 202d vibrate, thereby driving the vibration plate 202c to vibrate. Since the radius of the leakage hole is small, the vibration amplitude of the vibration block 202d is small, preventing the horizontal bolts from being converted to vertical by the vibration of the vibration plate 202c. At this time, the vertical bolts can be vibrated to be horizontal by the vibration of the vibration plate 202c, thereby increasing the number of horizontal bolts.

[0064] At this time, the bolts will slide in the sliding frame 201c and be transferred to the transfer bin 201e. When a bolt moves vertically, the vertically moving bolts can be guided back to the storage box 201a through the setting of the arc panel 201d, and the horizontally placed bolts will move to the transfer bin 201e. The height of the transfer bin 201e can only accommodate horizontally placed bolts, and vertically placed bolts will not enter the transfer bin 201e. The bolts can be moved to the discharge pipe 201f through the guidance of the transfer bin 201e. An inclined plate is provided at the top of the discharge pipe 201f. The surface block can prevent the bolt from flipping to the vertical direction when the bolt moves into the discharge tube 201f. The motor drives the baffle plate 201g to rotate so that the notch on the baffle plate 201g is separated from the discharge tube 201f. At this time, the bolt can fall to the top of the placement table 301a. The top of the placement table 301a is set as an arc surface, and the distance between the discharge tube 201f and the top of the placement table 301a is relatively close, so that the bolt can fall flat on the placement table 301a. The motor drives the baffle plate 201g to rotate slowly, so that the bolt can fall slowly.

[0065] When the push plate 201b moves, the movable ring 302k will be driven to move. The movable ring 302k moves on the driving column 302j, thereby driving the driving column 302j to rotate. The rotation of the driving column 302j can drive the movable disk 302g to rotate. The rotation of the movable disk 302g will drive the inclined surface block 302h to squeeze the inclined surface tooth groove. When squeezing the inclined surface tooth groove, the inclined surface block 302h can be moved to apply a squeezing force to the second spring 302i. When the inclined surface tooth groove moves to separate from the inclined surface block 302h, the rebound force of the second spring 302i can make the inclined surface block 302h return to its original position, and at this time, the tooth frame 302f will not be driven to rotate.

[0066] After the bolt is moved to the top of the placement table 301a, the push plate 201b will drop. When the push plate 201b drops, it can pull the pull rope 202l to drive the turntable 202h to rotate. When the turntable 202h rotates, it can apply a torsional force to the second torsion spring 202k. At the same time, the drop of the push plate 201b will drive the movable disk 302g to reverse. At this time, the inclined tooth groove will squeeze the inclined block 302h to drive the tooth frame 302f to rotate. The rotation of the tooth frame 302f can drive the belt 302e to rotate, and the rotation of the belt 302e can drive the pulley 302d to rotate. The pulley 302d can drive the driving wheel 302c to rotate by rotating. When the teeth on the driving wheel 302c rotate to contact the gear 302b, the gear 302b can be rotated 120 degrees. The rotation of the gear 302b will drive the rotating column 302a to rotate. The rotation of the rotating column 302a can drive the rotating table 301b to rotate. The rotating table 301b will drive the placement table 301a to rotate. When the placement table 301a is rotated to the bottom of the tapping machine 101, the guide groove provided on one side of the guide table 301g can guide the movable rod 301e to move the movable rod 301e The movement of the movable rod 301e will drive the rotating rod 301d to rotate, and the rotation of the rotating rod 301d will drive the push rod 301c to move. When the rotating rod 301d rotates, a torsional force can be applied to the first torsion spring 301f. The movement of the push rod 301c can squeeze the bolt so that the bolt can be fixed, and then the bolt can be tapped. After the bolt is tapped, the rotating table 301b will be rotated by the gear 302b to drive the placement table 301a to rotate until it is separated from the guide table 301g. At this time, the guide groove will release the squeezing of the movable rod 301e, and then the first torsion spring 301f will rotate. The force drives the movable rod 301e to return to its original position. When the placement table 301a is rotated to contact the other guide table 301g, the guide groove set on the other guide table 301g is in the reverse direction, which will drive the movable rod 301e to move in the reverse direction, and then drive the push rod 301c to move in the reverse direction, so that the bolt can be pushed off the placement table 301a. A leakage groove is set on the rotating table 301b. At this time, the bolt will fall into the leakage groove, and then be guided by the unloading bin set on the other guide table 301g, thereby completing the unloading of the bolt, and the processed bolt is moved to the workbench 103.
