Description

Technical Field

[0001] The invention relates to the technical field of bolts and nuts, in particular to a bolt and nut assembly processing device. Background Art

[0002] After the production of bolts and nuts is completed, the nuts need to be assembled on the screws. Assembling them together can reduce the scattering and loss of parts, facilitate sorting and counting, take up less space during storage and transportation, and be easier to manage and carry. At the same time, it can prevent the threads of the screws from being bumped, scratched, or contaminated with dust, debris, etc. during storage and transportation. During the assembly process, in order to improve the assembly efficiency, a bolt and nut assembly machine is needed. During use, the bolt and nut assembly machine can only sort and position the nuts. During assembly, it is necessary to manually hold the bolts and insert the bolts into the nuts to complete the assembly. In the assembly process of U-bolts, since the U-bolts need to be assembled with two nuts, there may be a situation of missing assembly when assembling the U-bolts and nuts manually, which makes the U-bolts lack effective protection. At the same time, the operation speed of inserting the nuts by manually holding the U-bolts is relatively slow, especially for U-bolts that need to be assembled with two nuts.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1

[0041] Reference Figure 1-Figure 9, which is the first embodiment of the present invention, and provides a bolt and nut assembly processing device, which includes a material storage component 200, including a stacking frame 201a, a threaded sleeve 201b, a first threaded rod 201c, a material baffle plate 201d, an extrusion rod 201e, a fixed frame 201f, a rotating rod 201g and a support plate 201h. The threaded sleeve 201b is rotatably connected to one side of the stacking frame 201a through a bearing, the first threaded rod 201c is threadedly connected to the threaded sleeve 201b, the material baffle plate 201d is located at the bottom of the stacking frame 201a, the extrusion rod 201e is located above the material baffle plate 201d, the fixed frame 201f is fixed to the top of the extrusion rod 201e, one end of the rotating rod 201g is hinged to the fixed frame 201f through a hinge plate, the support plate 201h is located below the stacking frame 201a, and the rotating rod 201g is rotatably connected to the stacking frame 201a through a rotating shaft.

[0042] The stacking frames 201a are U-shaped, and there are two of them, both located on one side of the machine body 101. The U-shaped bolts are placed through the two stacking frames 201a. One stacking frame 201a is fixed to the positioning track 103, and the other stacking frame 201a is movable. One end of the first threaded rod 201c is fixed to the stacking frame 201a, and the first threaded rod 201c can be driven to move by rotating the threaded sleeve 201b, so that the distance between the two stacking frames 201a can be adjusted, and U-shaped bolts with different spacings can be placed. The two stacking frames 201a are supported by telescopic rods for positioning the two to avoid offset during movement.

[0043] There are two baffle plates 201d, which are respectively located at the bottom of the two stacking frames 201a. The U-shaped bolts inside the stacking frames 201a are supported by the baffle plates 201d to prevent them from falling downward. A groove is provided on the baffle plate 201d, and the bottom end of the extrusion rod 201e is inclined. When the extrusion rod 201e moves downward, it can squeeze the inner wall of the groove. The cooperation of the two drives the baffle plate 201d to move, so that the baffle plate 201d can release the obstruction of the U-shaped bolt, and then the U-shaped bolt can fall downward to the top of the support plate 201h. At this time, one end of the U-shaped bolt located at the top of the support plate 201h is coaxial with the insertion hole on the positioning rail 103. When the U-shaped bolt moves horizontally, the end of the U-shaped bolt can be inserted into the positioning rail 103 and connected with the nut inside it. At this time, when the nut rotates, the assembly of the two can be completed.

[0044] A fixed rod is fixed on one side of the movable stacking frame 201a, which is inserted into the fixed frame 201f and movably connected to the fixed frame 201f. The two extrusion rods 201e can be connected through the cooperation of the two, so that the two extrusion rods 201e can move simultaneously, and one of the extrusion rods 201e can move with the stacking frame 201a.

[0045] A stabilizing rod is fixed on one side of the stacking frame 201a, and the extrusion rod 201e is movably connected to the outer side of the stabilizing rod. The extrusion rod 201e is supported and positioned by the stabilizing rod to avoid deviation during movement.

[0046] A positioning block is fixed on the top of the baffle plate 201d, and a positioning column is fixed on one side of the stacking frame 201a. The positioning column is movably connected to the positioning block, and the two are used together to support and position the baffle plate 201d. A fifth spring is sleeved on the outer side of the positioning column, and the two ends of the fifth spring are respectively fixed to the positioning block and the baffle plate 201d. The fifth spring applies a pulling force to the positioning block, and the positioning block drives the baffle plate 201d to move, so that the baffle plate 201d can be quickly reset after being separated from the bottom of the stacking frame 201a, thereby avoiding too many U-shaped bolts falling downward.

[0047] When one end of the rotating rod 201g moves upward, the other end thereof will drive the fixing frame 201f to move downward, so that the fixing frame 201f can drive the squeezing rod 201e to move downward.

[0048] The material pushing assembly 300 is arranged on one side of the material storing assembly 200, and includes a movable frame 301a, a connecting block 301b, a clamping block 301c and a second threaded rod 301d. The movable frame 301a is located on one side of the support plate 201h, the connecting block 301b is arranged in the movable frame 301a, the clamping block 301c is fixed on one side of the connecting block 301b, and the second threaded rod 301d is rotatably connected in the movable frame 301a.

[0049] There are two connecting blocks 301b, one is fixed inside the movable frame 301a, and the other is movably connected inside the movable frame 301a. The clamping block 301c is arc-shaped and has an open side. The height inside the clamping block 301c is slightly smaller than the diameter of the U-shaped bolt. Therefore, when the U-shaped bolt is inserted into the clamping block 301c, the two can be connected, so that when the clamping block 301c moves, it can drive the U-shaped bolt to move.

[0050] When the movable frame 301a moves, it will drive the connecting block 301b and the clamping block 301c to approach the U-shaped bolt and push the U-shaped bolt to move, so that the end of the U-shaped bolt can be inserted into the positioning track 103. At the same time, as the clamping block 301c continues to move, the U-shaped bolt can be inserted into the clamping block 301c, thereby connecting the two.

[0051] A threaded hole is provided in the movable connecting block 301b, and the second threaded rod 301d is threadedly connected to the threaded hole. The connecting block 301b can be driven to move by rotating the second threaded rod 301d, and the clamping block 301c can be driven to move by the connecting block 301b, so that the distance between the two clamping blocks 301c can be adjusted, so that U-shaped bolts with different spacings can be clamped and fixed.

[0052] The switching component 400 is arranged on one side of the pushing component 300, and includes a moving frame 401a, a moving block 401b, a rotating column 401c and a fixed shaft 401d. The moving frame 401a is located on one side of the movable frame 301a, the moving block 401b is fixed on one side of the movable frame 301a, and is movably connected to the moving frame 401a, the rotating column 401c is rotatably connected in the moving frame 401a, the fixed shaft 401d is fixed in the moving block 401b, a spiral groove 401c-1 is opened on the rotating column 401c, and the fixed shaft 401d slides in the spiral groove 401c-1.

[0053] When the nut is assembled at one end of the U-shaped bolt, the movable frame 301a will drive the clamping block 301c to move in the opposite direction, and drive the U-shaped bolt to move in the opposite direction through the clamping block 301c, so that the end of the U-shaped bolt moves out of the positioning track 103. At this time, the rotating column 401c will rotate, and drive the moving block 401b to move through the cooperation of the fixed shaft 401d and the spiral groove 401c-1, so that the moving block 401b drives the movable frame 301a to move, and then the movable frame 301a can drive the U-shaped bolt to move horizontally, and make the other end of the U-shaped bolt coaxial with the insertion hole on the positioning track 103. At this time, the movable frame 301a can drive the other end of the U-shaped bolt to be inserted into the positioning track 103 again when moving, thereby completing the nut assembly of the two ends of the U-shaped bolt.

[0054] Example 2

[0055] Reference Figure 1-Figure 18 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0056] Specifically, the switching assembly 400 further includes a rotating sleeve 402a, a gear 402b, a rack 402c, a first torsion spring 402d, a block 402e, a limiting column 402f, a rotating plate 402g and a baffle 402h. The rotating sleeve 402a is rotatably connected to one side of the moving frame 401a, the gear 402b is fixed to the outside of the rotating sleeve 402a, the rack 402c is arranged at the bottom of the gear 402b, and the two ends of the first torsion spring 402d are respectively connected to the rotating sleeve 402a and the rotating column 401c. The block 402e is fixed in the rotating sleeve 402a, a slot 401c-2 corresponding to the block 402e is provided on the rotating column 401c, the limiting column 402f is inserted into the moving frame 401a, the rotating plate 402g is located outside the limiting column 402f, and is rotatably connected with the moving frame 401a through a rotating shaft, the baffle 402h is arranged on one side of the bottom end of the rotating plate 402g, and a limiting hole 401c-3 corresponding to the limiting column 402f is provided on the rotating column 401c.

[0057] The baffle 402h is fixed to the top of the support sleeve 404b, the rotating sleeve 402a is rotatably connected to the movable frame 401a through a bearing, both ends of the block 402e are inclined, there are multiple slots 401c-2, which are evenly distributed in a ring shape on the outside of the rotating column 401c, there are multiple limit holes 401c-3, which are evenly distributed in a ring shape on the outside of the rotating column 401c, and the gear 402b is not engaged with the rack 402c in the initial state.

[0058] When the moving frame 401a drives the movable frame 301a to move, the gear 402b will mesh with the rack 402c and rotate at the top of the rack 402c, driving the rotating sleeve 402a to rotate through the gear 402b, and tightening and charging the first torsion spring 402d through the rotating sleeve 402a.

[0059] At the same time, the limiting column 402f will engage with the limiting hole 401c-3, and the rotation column 401c will be locked through the cooperation of the two, so that the charged first torsion spring 402d will not drive the rotation column 401c to rotate.

[0060] The travel of each movement of the moving frame 401a is fixed, so the length of the rack 402c can control the number of rotations of the gear 402b, thereby controlling the number of rotations of the first torsion spring 402d after releasing the torsion force, and then adjusting the travel of the U-bolt driven by the clamping block 301c to move horizontally, so that U-bolts with different spacings can be assembled.

[0061] When the movable frame 401a drives the active frame 301a to move in the opposite direction and reset, the bottom end of the rotating plate 402g will contact the baffle 402h and rotate due to the obstruction of the baffle 402h, so that the top end of the rotating plate 402g drives the limiting column 402f to move, and the limiting column 402f is separated from the limiting hole 401c-3, thereby releasing the restriction on the rotating column 401c. At this time, the rotating column 401c can be driven to rotate by the first torsion spring 402d. When the rotating column 401c rotates, the U-shaped bolt can be moved horizontally, and a nut can be assembled on the other end of the U-shaped bolt.

[0062] A blocking piece is fixed on the outside of the limiting column 402f, and the rotating plate 402g is in contact with the blocking piece, so that when the rotating plate 402g rotates, it can drive the limiting column 402f to move. A sixth spring is fixed at one end of the limiting column 402f, and the sixth spring applies a thrust to the limiting column 402f, so that the limiting column 402f and the limiting hole 401c-3 are more tightly engaged.

[0063] A seventh spring is fixed to one side of the block 402e, and the seventh spring applies a thrust to the block 402e, so that the block 402e and the slot 401c-2 are more tightly engaged. When the block 402e is engaged with the slot 401c-2 and the rotating sleeve 402a is rotating, the block 402e can be temporarily separated from the slot 401c-2 due to the inclined setting of the end of the block 402e, so that the rotating sleeve 402a can continue to rotate when the rotating column 401c is in a locked state.

[0064] When the rotating sleeve 402a stops rotating and the gear 402b is separated from the rack 402c, the rotating sleeve 402a can be prevented from being driven by the charged first torsion spring 402d to rotate in the opposite direction. Only when the block 402e is separated from the slot 401c-2 can the first torsion spring 402d release the torsional force.

[0065] The rack 402c is movably connected with a toothed plate inside, and a threaded column is threadedly connected to the toothed plate. The threaded column is rotatably connected to the rack 402c through a bearing. The toothed plate can be driven to move by rotating the threaded column. When the toothed plate moves, the length of the rack 402c can be adjusted.

[0066] Specifically, the switching assembly 400 also includes a push rod 403a, a fixed ring 403b, an extrusion plate 403c and an insertion rod 403d. The push rod 403a is inserted into the rotating sleeve 402a, the fixed ring 403b is fixed to one end of the push rod 403a, the extrusion plate 403c is located on one side of the fixed ring 403b, the insertion rod 403d is fixed on one side of the extrusion plate 403c, the block 402e is provided with a force groove 402e-1 corresponding to the push rod 403a, and the rotating sleeve 402a is provided with a socket 402a-1.

[0067] One side of the extrusion plate 403c is inclined, and the extrusion plate 403c and the support sleeve 404b are fixed to the top of the support sleeve 404b through a connecting frame. The inner wall of the force groove 402e-1 is inclined, and there are multiple jacks 402a-1, which are evenly distributed in a ring shape on the outside of the rotating sleeve 402a.

[0068] When the moving frame 401a is reset, the inclined surface of the extrusion plate 403c will push the fixed ring 403b to move, and the fixed ring 403b will drive the push rod 403a to squeeze the inclined surface of the inner wall of the force groove 402e-1, and the cooperation of the two will drive the block 402e to move, so that the block 402e is separated from the slot 401c-2, thereby releasing the connection between the rotating sleeve 402a and the rotating column 401c, so that the first torsion spring 402d can release the torsional force to drive the rotating column 401c to rotate.

[0069] At the same time, the insertion rod 403d will be inserted into the socket 402a-1, and the two will work together to lock the rotating sleeve 402a, so that the rotating sleeve 402a cannot rotate, thereby avoiding the situation where part of the power of the first torsion spring 402d acts on the rotating sleeve 402a when the torsion force is released, thereby preventing the rotating column 401c from rotating a sufficient number of times.

[0070] Specifically, the switching assembly 400 also includes a support rod 404a, a support sleeve 404b, a second spring 404c, a fixed plate 404d and a guide shaft 404e. The support rod 404a is fixed to the bottom of the rack 402c, the support sleeve 404b is located on the outside of the support rod 404a, the two ends of the second spring 404c are respectively fixed to the inner wall of the support sleeve 404b and the support rod 404a, the fixed plate 404d is fixed to one side of the support rod 404a, the guide shaft 404e is fixed to the bottom of the moving frame 401a, the fixed plate 404d is provided with a first sliding groove 404d-1, the guide shaft 404e slides in the first sliding groove 404d-1, the fixed plate 404d is provided with a guide groove 404d-2, and the fixed plate 404d is provided with a second sliding groove 404d-3.

[0071] The guide groove 404d-2 is inclined, and the first slide groove 404d-1 is connected to the second slide groove 404d-3 through the guide groove 404d-2. When the guide shaft 404e is located inside the first slide groove 404d-1, the gear 402b and the rack 402c can engage with each other. When the guide shaft 404e is located inside the second slide groove 404d-3, the gear 402b and the rack 402c cannot engage with each other.

[0072] The support rod 404a is L-shaped, and there are two support sleeves 404b, which are used to support the rack 402c. One side of the support sleeve 404b is fixed to the mounting frame 305b.

[0073] At this time, when the nut is assembled on the first end of the U-shaped bolt, the moving frame 401a will drive the guide shaft 404e to slide in the first slide groove 404d-1 when it moves. At this time, the gear 402b and the rack 402c can engage with each other. When the guide shaft 404e moves to the inner end of the first slide groove 404d-1, it will enter the guide groove 404d-2. When the guide shaft 404e moves in the reverse direction, it will enter the second slide groove 404d-3 through the guide groove 404d-2. At this time, the support rod 404a will be pushed to move, and the rack 402c will be driven to move by the support rod 404a, so that the gear 402b and the rack 402c cannot engage with each other, thereby preventing the gear 402b from rotating in the opposite direction at the top of the rack 402c when it moves in the reverse direction, thereby releasing the energy of the tightened first torsion spring 402d.

[0074] When it is necessary to assemble a nut on the second end of the U-bolt, the moving frame 401a moves again and moves the guide shaft 404e in the second slide groove 404d-3. At this time, the gear 402b will not rotate, and the first torsion spring 402d will not be tightened. When the guide shaft 404e enters the guide groove 404d-2 and the moving frame 401a moves in the reverse direction, the second spring 404c applies a pulling force to the support rod 404a and the fixed plate 404d, so that the fixed plate 404d is reset, so that the guide shaft 404e can enter the first slide groove 404d-1.

[0075] At the same time, the gear 402b is meshed with the rack 402c again. When the gear 402b is reset, it will rotate in the opposite direction through the cooperation of the rack 402c, and tighten the first torsion spring 402d in the opposite direction to charge it. When the movable frame 401a moves to the initial position, the first torsion spring 402d can drive the rotating column 401c to rotate in the opposite direction, so that the movable frame 301a and the clamping block 301c can be moved to the initial position, and the nut can be assembled on the other U-bolt again.

[0076] The working principle is as follows: after the movable frame 301a pushes the U-shaped bolt to move once and assembles a nut on the end of the U-shaped bolt, when the movable frame 301a moves in the opposite direction and resets, it will drive the U-shaped bolt to move laterally so that the other end of the U-shaped bolt coincides with the nut. When the movable frame 301a drives the U-shaped bolt to move again, the nut can be assembled on the other end of the U-shaped bolt. When the movable frame 301a is reset again, it will move in the opposite direction of the initial lateral movement and reset, so that the nut can be assembled on the other U-shaped bolt.

[0077] Specifically, the switching assembly 400 also includes a blocking rod 405a, a block 405b, a moving rod 405c, a force block 405d, an extrusion bar 405e, a connecting rod 405f, a rotating rod 405g and a sliding shaft 405h. The blocking rod 405a is arranged on the fixed plate 404d, the block 405b is located on one side of the blocking rod 405a, the moving rod 405c is fixed to one side of the block 405b, the force block 405d is fixed to one side of the moving rod 405c, the extrusion bar 405e is located on one side of the force block 405d, the connecting rod 405f is fixed to one end of the extrusion bar 405e, the rotating rod 405g is rotatably connected to the fixed plate 404d through a rotating shaft, and the sliding shaft 405h is fixed to one end of the connecting rod 405f.

[0078] A movable groove is provided on the fixed plate 404d, and the blocking rod 405a is rotatably connected to the movable groove through the rotating shaft 405a-2, and the rotating shaft 405a-2 is fixed to the inner wall of the movable groove. A second torsion spring 405a-1 is fixed to the top of the blocking rod 405a, and the second torsion spring 405a-1 is fixed to the rotating shaft 405a-2. When the blocking rod 405a rotates, it is reset by the second torsion spring 405a-1.

[0079] When the guide shaft 404e moves in the first slide groove 404d-1 and contacts the blocking rod 405a, it will push the blocking rod 405a to rotate. At this time, the guide shaft 404e will enter the guide groove 404d-2. When the guide shaft 404e moves in the opposite direction, the blocking rod 405a will hinder the guide shaft 404e, making it unable to enter the first slide groove 404d-1, and can only enter the second slide groove 404d-3 along the guide groove 404d-2.

[0080] The blocking rod 405a is limited by the stopper 405b, and the blocking rod 405a can be pushed to rotate only when the guide shaft 404e moves into the guide groove 404d-2 through the first slide groove 404d-1. When the blocking rod 405a moves into the first slide groove 404d-1 in the guide groove 404d-2, it cannot push the blocking rod 405a to rotate, and can only enter the second slide groove 404d-3.

[0081] A chamber is provided on the fixed plate 404d, and the rotating rod 405g is rotatably connected to the chamber via a rotating shaft. The rotating rod 405g itself is elastic, and when it is squeezed by the guide shaft 404e and cannot rotate, it bends, thereby allowing the guide shaft 404e to continue to move unhindered.

[0082] The connecting rod 405f is L-shaped, and one side of the force block 405d is inclined. A sliding groove is provided on the rotating rod 405g, and the sliding shaft 405h slides in the sliding groove. The rotating rod 405g is connected to the connecting rod 405f through the cooperation of the two, so that the connecting rod 405f can drive the connecting rod 405f to move when the connecting rod 405f rotates.

[0083] When the guide shaft 404e moves in the second slide groove 404d-3 toward the guide groove 404d-2, it contacts the rotating rod 405g and pushes the rotating rod 405g to rotate. When the rotating rod 405g rotates, it pushes the connecting rod 405f and the extrusion bar 405e to move, so that the end of the extrusion bar 405e squeezes the inclined surface of the force block 405d. The cooperation of the two drives the moving rod 405c and the stopper 405b to move, so that the stopper 405b can be separated from the blocking rod 405a, thereby releasing the restriction on the blocking rod 405a.

[0084] At this time, when the guide shaft 404e moves from the guide groove 404d-2 to the first sliding groove 404d-1, it will not be hindered and can be reset along the first sliding groove 404d-1.

[0085] When the guide shaft 404e moves from the first slide groove 404d-1 to the guide groove 404d-2 again, it will push the rotating rod 405g to rotate to the initial state, and drive the connecting rod 405f and the extrusion bar 405e to move through the rotating rod 405g, so that the extrusion bar 405e is separated from the force block 405d.

[0086] An eighth spring is fixed to one side of the moving rod 405c. At this time, the eighth spring pushes the moving rod 405c and the stopper 405b to reset, so that the stopper 405b can limit the blocking rod 405a again.

[0087] Specifically, the pusher assembly 300 further includes an extrusion block 302a and a limiting plate 302b. The extrusion block 302a is located above the movable frame 301a. The limiting plate 302b is fixed to the top of the movable frame 301a and is located on one side of the extrusion block 302a.

[0088] One side of the extrusion block 302a is inclined, and the extrusion block 302a is hinged to the top of the movable frame 301a through a hinge seat. A support shaft is fixed inside the extrusion block 302a, and a third torsion spring is fixed outside the support shaft. One end of the third torsion spring is fixed to the hinge seat.

[0089] When the movable frame 301a moves horizontally for the first time, the vertical side of the squeezing block 302a will contact the rotating rod 201g and rotate due to the squeezing of the rotating rod 201g. The squeezing block 302a can be reset by the third torsion spring. When the movable frame 301a is reset, the squeezing block 302a will be driven to squeeze the top of the rotating rod 201g with the inclined surface, thereby pushing the rotating rod 201g to move upward, and then the other end of the rotating rod 201g can drive the fixed frame 201f to move downward.

[0090] The extrusion block 302a is blocked by the limiting plate 302b so that it will not rotate when pushing the rotating rod 201g to move upward.

[0091] Example 3

[0092] Reference Figure 1-Figure 18 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0093] Specifically, the pusher assembly 300 also includes a support frame 303a, an interception block 303b and a third spring 303c. The support frame 303a is located on one side of the support plate 201h, the interception block 303b is arranged in the support frame 303a, and the two ends of the third spring 303c are respectively fixed to the inner wall of the support frame 303a and the interception block 303b.

[0094] The support frame 303a is fixed to the body 101 through a fixing frame, and one side of the interception block 303b is inclined. When the clamping block 301c drives the U-shaped bolt to move horizontally, the U-shaped bolt will contact the inclined surface of the interception block 303b and push the interception block 303b to move upward. When the clamping block 301c moves in the opposite direction, the U-shaped bolt will contact the vertical side of the interception block 303b and be hindered by the interception block 303b and cannot move with the clamping block 301c, thereby separating the U-shaped bolt from the clamping block 301c and falling downward, so that the assembled U-shaped bolt can be cut.

[0095] The third spring 303c is used to apply a downward thrust to the interception block 303b so that it can be reset after moving.

[0096] Specifically, the pusher assembly 300 also includes a top plate 304a, a fixed column 304b, a fixed sleeve 304c and a fourth spring 304d. The top plate 304a is located on the top of the support plate 201h, the fixed column 304b is fixed to one side of the top plate 304a, the fixed sleeve 304c is located on the outside of the fixed column 304b, and the two ends of the fourth spring 304d are fixed to the inner walls of the fixed column 304b and the fixed sleeve 304c.

[0097] One side of the fixing sleeve 304c is fixed to the body 101. When the U-shaped bolt moves for the first time, the end without the nut will contact the top plate 304a. As the U-shaped bolt moves, the top plate 304a will be pushed to move. In this way, the U-shaped bolt can be supported by the top plate 304a so that its end will not move easily. Only when the clamping block 301c is completely stuck on the outside of the U-shaped bolt can the U-shaped bolt be pushed to move.

[0098] The fourth spring 304d is used to support the fixing column 304b and the top plate 304a so that they will not move easily after being squeezed by the U-shaped bolt.

[0099] Specifically, the pusher assembly 300 further includes a cylinder 305a and a mounting frame 305b. The output end of the cylinder 305a is fixed to the moving frame 401a, and the mounting frame 305b is arranged outside the cylinder 305a.

[0100] The mounting frame 305b is used to support the cylinder 305a, and the cylinder 305a is used to drive the moving frame 401a to move.

[0101] Specifically, it also includes a main body component 100, which is arranged on one side of the material storage component 200, including a body 101, a material distribution hopper 102 and a positioning track 103. The body 101 is arranged on one side of the material storage component 200, the material distribution hopper 102 is located on the top of the body 101, and the positioning track 103 is fixed on one side of the body 101.

[0102] The dividing hopper 102 can stack the nuts as a whole in the positioning track 103. When the end of the U-shaped bolt is inserted into the positioning track 103, the nut can be driven to rotate through the machine body 101, and then the nut can be assembled on the outside of the U-shaped bolt. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0103] When in use, start the cylinder 305a to drive the moving frame 401a and the movable frame 301a to move. When the movable frame 301a moves, it will drive the connecting block 301b and the clamping block 301c to approach the U-shaped bolt and push the U-shaped bolt to move, so that the end of the U-shaped bolt can be inserted into the positioning track 103. At the same time, as the clamping block 301c continues to move, the U-shaped bolt can be inserted into the inside of the clamping block 301c, so that the two can be connected.

[0104] When the nut is assembled at one end of the U-shaped bolt, the movable frame 301a will drive the clamping block 301c to move in the opposite direction, and drive the U-shaped bolt to move in the opposite direction through the clamping block 301c, so that the end of the U-shaped bolt moves out of the positioning track 103. At this time, the rotating column 401c will rotate, and drive the moving block 401b to move through the cooperation of the fixed shaft 401d and the spiral groove 401c-1, so that the moving block 401b drives the movable frame 301a to move, and then the movable frame 301a can drive the U-shaped bolt to move horizontally, and make the other end of the U-shaped bolt coaxial with the insertion hole on the positioning track 103. At this time, the movable frame 301a can drive the other end of the U-shaped bolt to be inserted into the positioning track 103 again when moving, thereby completing the nut assembly of the two ends of the U-shaped bolt.

[0105] When the movable frame 301a is reset, it will drive the extrusion block 302a to squeeze the oblique surface of the rotating rod 201g, thereby pushing the rotating rod 201g to move upward, and then the other end of the rotating rod 201g can drive the fixed frame 201f to move downward, so that the fixed frame 201f drives the extrusion rod 201e to move downward. When the extrusion rod 201e moves downward, it can squeeze the inner wall of the groove. Through the cooperation of the two, the baffle plate 201d is driven to move, so that the baffle plate 201d can release the obstruction of the U-shaped bolt, and then the U-shaped bolt can fall downward to the top of the support plate 201h. When the movable frame 301a moves again, the nut of the other U-shaped bolt can be assembled.

[0106] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
