[0036] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-8 As shown, in this embodiment, a non-standard fastener positioning and assembly device includes a base 1. The top of the base 1 is fixedly connected to a mounting housing 12 via a support frame 11, which is used to install an assembly component 2. The assembly component 2 is arranged inside the mounting housing 12. The assembly component 2 includes a rotating tube 21 rotatably mounted inside the mounting housing 12. The rotating tube 21 can rotate on the mounting housing 12 while also performing linear reciprocating motion synchronously.

[0038] The bottom of the rotating tube 21 extends through to the outside of the mounting shell 12 and is fixedly connected to the limited mounting seat 22. On the one hand, it is used for the installation of the clamping claw 24. On the other hand, it is used to rotate the non-standard bolt supported on the bolt receiving seat 32 to avoid the problem that when the pushing assembly 5 pushes the nut to rise and contacts the non-standard bolt, the non-standard bolt is pushed up synchronously, which makes it difficult to quickly complete the assembly of the non-standard bolt and the nut. The two sides of the limited mounting seat 22 are symmetrically connected to the clamping gear 23, and the clamping gear 23 is fixedly connected to the clamping claw 24. The rotation of the clamping gear 23 drives the corresponding clamping claw 24 to move relative to each other, thereby fixing the non-standard bolt. The end screw of the clamping claw 24 is connected to the elastic rubber clamping block to achieve stable clamping and rotation of the non-standard bolt.

[0039] A blanking assembly 3 is provided at the bottom of the mounting shell 12. The blanking assembly 3 includes a rotating tube 31 rotatably connected to one side of the bottom of the mounting shell 12. A bolt receiving seat 32 and a nut receiving seat 33 are detachably connected to the annular outer wall of the rotating tube 31. The bolt receiving seat 32 is located above the nut receiving seat 33, and the connection between the two and the rotating tube 31 is specifically a clamping or screw connection, which is used to receive bolts and nuts of different types. A placement groove 1 is provided on the top of the nut receiving seat 33 to prevent the nut from falling off the nut receiving seat 33. A gasket placement assembly 4 is provided on the rotating tube 31 and above the nut receiving seat 33.

[0040] A push assembly 5 is provided on the rotating tube 31. The push assembly 5 includes a movable rod 51 movably mounted inside the rotating tube 31. The bottom of the movable rod 51 is fixedly connected to a push column 53 via a support plate 52. The push column 53 is located directly below the limit mounting seat 22. The rise of the movable rod 51 in combination with the support plate 52 drives the push column 53 to rise synchronously, thereby driving the nut and gasket to contact the non-standard bolt above, thereby automatically completing the assembly of the non-standard fastener.

[0041] The top of the base 1 is equipped with a bolt conveying channel 13, a gasket conveying channel 14 and a nut conveying channel 15. The non-standard bolts are conveyed to the bolt receiving seat 32 through the cooperation of the bolt conveying channel 13 and the corresponding vibration disk. The gaskets are conveyed to the gasket placement assembly 4 through the cooperation of the gasket conveying channel 14 and the nuts are conveyed to the nut receiving seat 33 through the cooperation of the nut conveying channel 15 and the corresponding vibration disk.

[0042] The top bolt of the mounting shell 12 is connected to a motor 25, and the output shaft of the motor 25 is fixedly connected to a drive shaft 26 that is rotatably connected to the mounting shell 12, and the drive shaft 26 is fixedly connected to a drive gear 27. The rotating tube 21 is fixedly connected to a transmission gear 28 that meshes with the drive gear 27. The motor 25 drives the drive gear 27 to rotate through the drive shaft 26, and the drive gear 27 meshes with the transmission gear 28 to drive the rotating tube 21 to rotate, thereby forcing the two sets of jaws 24 on the limit mounting seat 22 to rotate.

[0043] An auxiliary rod 29 is installed inside the rotating tube 21. The bottom of the auxiliary rod 29 is fixedly connected to a cylindrical rack 210 meshing with the clamping gears 23 on both sides. The top of the auxiliary rod 29 is rotatably connected to a connecting plate 54 fixedly connected to the movable rod 51. When the auxiliary rod 29 moves away from the limit mounting seat 22, the auxiliary rod 29 carries the cylindrical rack 210 meshing with the clamping gears 23 on both sides to move, thereby driving the clamping jaws 24 to move relative to each other, clamping and rotating the non-standard bolts. When the auxiliary rod 29 moves close to the limit mounting seat 22, it drives the clamping jaws 24 to expand and release the clamping of the non-standard bolts. The auxiliary rod 29 is fixedly connected to the industrial wheel 211, and the rotating tube 21 is fixedly connected to the industrial wheel 1 212.

[0044] A rotating wheel 213 is fixedly connected to the driving shaft 26, and a guide groove 1 214 and a guide groove 215 are provided on the annular outer wall of the rotating wheel 213. The top of the installation shell 12 is symmetrically fixedly connected with a slide bar 16, and two groups of pushing blocks 216 cooperating with the type wheel 1 212 and the type wheel 2 211 are slidably connected between the slide bars 16. The provided slide bar 16 is used to increase the stability of the linear motion of the two groups of pushing blocks 216. A guide pin 217 is fixedly connected to the pushing block 216, and the two ends of the guide pin 217 are respectively plugged into the corresponding guide groove and the type wheel, so that when the driving shaft 26 drives the rotating wheel 213, the guide groove 1 214 and the guide groove 2 215 on the rotating wheel 213 cooperate with the corresponding pushing block 216, so that the rotating tube 21 can perform a lifting motion during the rotation process, and drive the auxiliary rod 29 to perform two lifting motions.

[0045] Guide groove 1 214 includes a horizontal retreat section 1 and a horizontal assembly section 1, with an oblique guide section smoothly transitioning between the two sections. Guide groove 215 includes a horizontal retreat section 2 and a horizontal assembly section 2, with a V-shaped guide section smoothly transitioning between the two sections. One end of the guide pins 217 on the two sets of push blocks 216 is respectively placed in the initial positions of guide groove 1 214 and guide groove 2 215, namely, the horizontal retreat section 1 and the horizontal retreat section 2.

[0046] When the guide pin 217 is in the horizontal retreat section, the limit mounting seat 22 and the clamping jaws 24 will not interfere with the process of the non-standard bolt moving to the bolt receiving seat 32. As the rotating wheel 213 rotates, the guide pin 217 on the lower pushing block 216 first enters the oblique guide section from the horizontal retreat section 1, and the other end of the guide pin 217 on the lower pushing block 216 cooperates with the type wheel 1 212 to synchronously push the rotating tube 21 downward, forcing the bottom of the limit mounting seat 22 to contact the top of the non-standard bolt. After that, the guide pin 217 on the lower pushing block 216 enters the horizontal assembly section 1 from the oblique guide section, ensuring the rotation of the position of the limit mounting seat 22 after it is lowered, preparing for the clamping jaws 24 to clamp the non-standard bolt;

[0047] As the rotating tube 21 descends, the guide pin 217 on the upper push block 216 simultaneously enters the V-shaped guide section from the second horizontal retreat section. The other end of the guide pin 217 on the upper push block 216 cooperates with the second work wheel 211 to first push the auxiliary rod 29 carrying the cylindrical rack 210 to follow the downward movement of the rotating tube 21. After the rotating tube 21 descends to the lowest point, the guide pin 217 on the upper push block 216 enters the lowest point in the V-shaped guide section. That is, the auxiliary rod 29 and the rotating tube 21 descend synchronously and the descending distance is the same.

[0048] During the descent of the auxiliary rod 29, the connecting plate 54 drives the movable rod 51 to move downward synchronously in the rotating tube 31, thereby driving the push column 53 and the positioning rod 57 to move to the bottom of the nut receiving seat 33, so that the gasket is conveyed to the top of the gasket placement assembly 4 through the gasket conveying channel 14, and the matching nut is conveyed to the top of the nut receiving seat 33 through the nut conveying channel 15;

[0049] Afterwards, the guide pin 217 on the upper pushing block 216 moves upward under the guidance of the V-shaped guide section, and then pushes the auxiliary rod 29 to carry the cylindrical rack 210 to move upward. The cylindrical rack 210 and the clamping gears 23 engaged on both sides drive the clamping claws 24 to move relative to each other, clamping and rotating the non-standard bolt. During the upward process of the auxiliary rod 29 carrying the movable rod 51, the pushing column 53 rises synchronously, and pushes the nut and gasket to rise and contact the non-standard bolt. Combined with the rotation of the non-standard bolt, the automatic assembly of non-standard fasteners is realized, thereby solving the problem that the existing assembly equipment cannot complete the gasket assembly synchronously.

[0050] A horizontal section is provided at the bottom of one of the V-shaped guide sections on the second guide groove 215, so that the auxiliary rod 29 has a certain residence time during the process of descending for the second time and rising again, which is used to rotate the rotating tube 31 and switch the receiving seat to achieve the effect of automatic unloading.

[0051] There are two groups of bolt receiving seats 32 and nut receiving seats 33, which are used to alternately receive non-standard bolts, nuts and washers, thereby shortening the residence time of the auxiliary rod 29 after the second descent and during the ascending process, and improving assembly efficiency. A driven gear 34 is fixedly connected to the outer wall of the rotating tube 31, and a second motor 35 is installed on the bottom bolt of the mounting housing 12. Specifically, it is a servo motor for accurately controlling the rotation angle of the rotating tube 31, and a driving gear 36 meshing with the driven gear 34 is fixedly connected to the output shaft of the second motor 35. An L-shaped blanking guide plate 37 is fixedly connected to the bottom of the mounting housing 12.

[0052] After the non-standard fasteners are assembled, the guide pin 217 on the upper push block 216 enters the V-shaped guide section on the other side from the horizontal assembly section 2, and the other end of the guide pin 217 on the upper push block 216 cooperates with the second work wheel 211 to first push the auxiliary rod 29 to carry the cylindrical rack 210 downward. The cylindrical rack 210 is meshed with the clamping gears 23 on both sides to drive the clamping claws 24 to expand and release the clamping of the bolt. At this time, the push column 53 is lowered again to the bottom of the nut receiving seat 33;

[0053] Then, the guide pin 217 on the upper push block 216 slides within the horizontal section of the V-shaped guide section on the other side. The auxiliary rod 29 temporarily stops rising, and the push column 53 does not interfere with the rotation of the rotating tube 31. The second motor 35 drives the rotating tube 31 to quickly rotate 180 degrees through the meshing driving gear 36 and the driven gear 34, so that each receiving seat on the other side of the rotating tube 31 contacts the corresponding conveying channel.

[0054] During this process, the assembled fastener is pushed out from the bolt receiving seat 32 in conjunction with the blanking guide plate 37 below the mounting housing 12. Finally, the guide pin 217 on the upper push block 216 moves upward under the guidance of the V-shaped guide section on the other side and then enters the second horizontal retreat section. During this process, the auxiliary rod 29 is pushed to carry the cylindrical rack 210 for a second upward movement. At the same time, the push column 53 is again inserted into the corresponding nut receiving seat 33 and the gasket placement assembly 4.

[0055] As the upper pushing block 216 rises, the guide pin 217 on the lower pushing block 216 enters the oblique guide section on the other side from the horizontal assembly section 1, and combines the other end of the guide pin 217 on the lower pushing block 216 with the I-type wheel 1 212 to push the rotating tube 21 to rise synchronously with the auxiliary rod 29, forcing the limit mounting seat 22 to separate from the non-standard bolt, and then enter the horizontal retreat section 1 to ensure the expansion state of the clamping jaws 24 and to transport and assemble the non-standard bolts, washers and nuts again.

[0056] A mounting groove 38 is symmetrically provided on the outer wall of the rotating tube 31 for mounting a bent plate 41, and pins are symmetrically fixedly connected on both sides of the mounting groove 38. The gasket placement assembly 4 includes a bent plate 41 rotatably connected to the pin, an abutment rod 42 is fixedly connected to one side of the bent plate 41 located in the mounting groove 38, a gasket receiving seat 43 is detachably connected to the free end of the bent plate 41, a torsion spring 44 is fixedly connected between the bent plate 41 and the mounting groove 38 and located on the outer side of the pin, and an annular clearance groove 55 is provided on the annular outer wall of the movable rod 51;

[0057] When the push column 53 is located inside the corresponding nut receiving seat 33 and the gasket placement assembly 4, the ends of multiple abutment rods 42 contact the outer wall of the movable rod 51, and cooperate with the pin shaft to force the bending plate 41 to drive the distance between the two groups of gasket receiving seats 43 to be minimized, so as to effectively support the gasket. As the movable rod 51 rises, the annular give way groove 55 moves to the abutment rod 42 area. Under the action of the torsion spring 44, the two groups of bending plates 41 are forced to move away from each other with the pin shaft as the rotation axis, carrying the corresponding gasket receiving seats 43, so as to prompt the nut rising below to pass between the two groups of gasket receiving seats 43, thereby avoiding interference with the rising assembly of the nut by the gasket receiving seats 43.

[0058] Example 2: Please refer to Figure 6 and Figure 9As shown, in this embodiment, a plurality of chute 1s 56 are equidistantly formed on the annular outer wall of the push column 53. A positioning rod 57 is slidably connected to the interior of the chute 1 56, and a spring 1 58 is fixedly connected between the bottom of the positioning rod 57 and the chute 1 56. By providing multiple sets of positioning rods 57 on the push column 53, when the push column 53 rises, the multiple sets of positioning rods 57 are passed through the interior of the nut and the washer, thereby achieving the positioning coincidence of the nut and the washer and the central axis of the non-standard bolt, thereby improving the assembly accuracy of the non-standard fastener.

[0059] The provided slide groove 56 and spring 58 are used to separate the positioning rod 57 from the nut after the top of the positioning rod 57 contacts the non-standard bolt under the abutment of the limit mounting seat 22, thereby realizing the contact between the nut and the non-standard bolt. The two sides of the positioning rod 57 are symmetrically fixedly connected to the limit blocks, and the inner wall of the slide groove 56 is provided with a limit groove that is slidably connected to the corresponding limit block, which is used to improve the stability of the linear motion of the positioning rod 57.

[0060] A second chute 59 is formed at the top of the positioning rod 57. A trapezoidal guide block 510 is slidably connected to the interior of the second chute 59. A second spring 511 is fixedly connected between the bottom of the trapezoidal guide block 510 and the second chute 59. The trapezoidal guide block 510 provided on the corresponding positioning rod 57 is used to guide the offset washers and nuts on the receiving seat, so that multiple sets of positioning rods 57 can be smoothly inserted into the washers and nuts, and the second chute 59 cooperates with the second spring 511.

[0061] Compared with directly opening a guide surface on the positioning rod 57, it can effectively avoid the problem that the positioning rod 57 cannot continue to play the positioning effect during the separation process with the gasket and the nut, thereby causing the problem of being unable to continue assembly. The two sides of the trapezoidal guide block 510 are symmetrically fixed with limit pins, and the inner wall of the slide groove 59 is provided with a limit groove that is slidably connected to the corresponding limit pin, which is used to improve the stability of the linear motion of the trapezoidal guide block 510.

[0062] An abutment ring 512 is sleeved on the outer side of the multiple groups of positioning rods 57. The top of the abutment ring 512 is provided with an anti-slip groove to prevent the nut from rotating in contact with the non-standard bolt. The bottom of the abutment ring 512 is fixedly connected to an L-shaped rod 513 located between two adjacent positioning rods 57. The annular outer wall of the push column 53 is provided with a third slide groove 514 that is slidably connected to the corresponding L-shaped rod 513. A third spring 515 is fixedly connected between the bottom of the L-shaped rod 513 and the third slide groove 514.

[0063] An abutment ring 512 is provided on the outer side of the multiple groups of positioning rods 57 to abut the bottom of the nut, so that when the push column 53 moves upward, the nut and the gasket are effectively pushed upward. At the same time, the L-shaped rod 513, the slide groove three 514 and the spring three 515 can prevent the nut and the clamping jaw 24 from being rigidly squeezed by the non-standard bolt that is not fully clamped and rotated, thereby causing damage to the fastener or assembly equipment.

[0064] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
