[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1-Figure 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 shell 12 through a support frame 11, and is used to install an assembly component 2. The mounting shell 12 is provided with an assembly component 2 inside. The assembly component 2 includes a rotating tube 21 rotatably mounted inside the mounting shell 12. The rotating tube 21 can rotate on the mounting shell 12 and simultaneously perform linear reciprocating motion;

[0038] The bottom of the rotating tube 21 extends through and extends to the outside of the mounting shell 12 and is fixedly connected to the limited position mounting seat 22. On the one hand, it is used for the installation of the clamping claw 24, and on the other hand, it is used to rotate against the non-standard bolts received on the bolt receiving seat 32, so as to avoid the problem that when the jacking assembly 5 pushes the nut up and contacts the non-standard bolt, the non-standard bolt is pushed up synchronously, and it is difficult to quickly complete the assembly of the non-standard bolt and the nut. The two sides of the limited position 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 clamping gear 23 rotates to drive the corresponding clamping claw 24 to move relatively, thereby fixing the non-standard bolt. The end screws of the clamping claw 24 are 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, and the blanking assembly 3 includes a rotating tube 31 rotatably connected to one side of the bottom of the mounting shell 12, and a bolt receiving seat 32 and a nut receiving seat 33 are detachably connected on the annular outer wall of the rotating tube 31, and the bolt receiving seat 32 is located above the nut receiving seat 33, and the connection method between the two and the rotating tube 31 is specifically a clamping connection or a screw connection, which is used to receive bolts and nuts of different models, and 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, and a gasket placement assembly 4 is provided on the rotating tube 31 and located above the nut receiving seat 33;

[0040] The rotating tube 31 is provided with a push assembly 5, which includes a movable rod 51 movably mounted inside the rotating tube 31, and a push column 53 is fixedly connected to the bottom of the movable rod 51 through a support plate 52, and the push column 53 is located directly below the limit mounting seat 22. The movable rod 51 rises in combination with the support plate 52 to drive 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] A bolt conveying channel 13, a gasket conveying channel 14 and a nut conveying channel 15 are installed on the top of the base 1. The bolt conveying channel 13 cooperates with the corresponding vibration disk to convey the non-standard bolts to the bolt receiving seat 32. The gasket conveying channel 14 cooperates with the corresponding vibration disk to convey the gasket to the gasket placement assembly 4. The nut conveying channel 15 cooperates with the corresponding vibration disk to convey the nuts to the nut receiving seat 33.

[0042] The top bolt of the mounting shell 12 is connected with a motor 25, and a driving shaft 26 rotatably connected to the mounting shell 12 is fixedly connected to the output shaft of the motor 25, and a driving gear 27 is fixedly connected to the driving shaft 26. A transmission gear 28 meshing with the driving gear 27 is fixedly connected to the rotating tube 21. The motor 25 drives the driving gear 27 to rotate through the driving shaft 26, and the driving 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. The auxiliary rod 29 moves away from the limit mounting seat 22, and 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 a second work-shaped wheel 211, and the rotating tube 21 is fixedly connected to a first work-shaped wheel 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. A sliding rod 16 is symmetrically fixedly connected to the top of the installation shell 12, and two groups of pushing blocks 216 cooperating with the I-shaped wheel 1 212 and the I-shaped wheel 211 are slidably connected between the sliding rods 16. The provided sliding rod 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 I-shaped 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] The guide groove 1 214 includes a horizontal retreat section 1 and a horizontal assembly section 1, and an oblique guide section is smoothly connected between the horizontal retreat section 1 and the horizontal assembly section 1. The guide groove 215 includes a horizontal retreat section 2 and a horizontal assembly section 2, and a V-shaped guide section is smoothly connected between the horizontal retreat section 2 and the horizontal assembly section 2. One end of the guide pins 217 on the two sets of push blocks 216 are respectively placed in the initial positions of the guide groove 1 214 and the guide groove 2 215, that is, the horizontal retreat section 1 and the horizontal retreat section 2.

[0046] When the guide pin 217 is located in the horizontal retreat section, the limit mounting seat 22 and the clamping jaw 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 push 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 push block 216 cooperates with the type wheel 1 212 to synchronously push the rotating tube 21 to move 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 push block 216 enters the horizontal assembly section 1 from the oblique guide section to ensure the rotation of the position of the limit mounting seat 22 after it is lowered, so as to prepare for the clamping jaw 24 to clamp the non-standard bolt.

[0047] When the rotating tube 21 descends, the guide pin 217 on the upper push block 216 enters the V-shaped guide section from the second horizontal retreat section at the same time, 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 to follow the downward movement of the rotating tube 21, until the rotating tube 21 descends to the lowest point, and 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 descending process of the auxiliary rod 29, the movable rod 51 is driven to descend synchronously in the rotating tube 31 through the connecting plate 54, thereby driving the push column 53 to carry 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 push 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, and the clamping claw 24 is driven to move relative to the clamping gear 23 meshing with the cylindrical rack 210 on both sides, so as to clamp and rotate the non-standard bolt. During the ascending process of the auxiliary rod 29 carrying the movable rod 51, the push column 53 rises synchronously, and pushes the nut and the gasket to rise and contact the non-standard bolt, and combined with the rotation of the non-standard bolt, the automatic assembly of the non-standard fastener is realized, thereby solving the problem that the existing assembly equipment cannot synchronously complete the gasket assembly;

[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 for rotating the rotating tube 31 and switching the receiving seat to achieve the effect of automatic unloading.

[0051] The number of bolt receiving seats 32 and nut receiving seats 33 is two groups, which are used to alternately receive non-standard bolts, nuts and washers, thereby shortening the residence time of the auxiliary rod 29 after the secondary descent and during the ascending process, and improving the assembly efficiency. A driven gear 34 is fixedly connected to the outer wall of the rotating tube 31, and a motor 2 35 is installed on the bottom bolt of the mounting housing 12, specifically a servo motor, which is used to accurately control 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 motor 2 35, and an L-shaped material discharge 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 to move downward, and the clamping claw 24 is driven to expand and move through the cylindrical rack 210 and the clamping gears 23 meshing on both sides to 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] After that, the guide pin 217 on the upper push block 216 slides in the horizontal section of the V-shaped guide section on the other side, the auxiliary rod 29 does not move upward temporarily, the push column 53 does not interfere with the rotation of the rotating tube 31, and the second motor 35 drives the rotating tube 31 to rotate 180 degrees quickly 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] In this process, the assembled fastener is pushed out from the bolt receiving seat 32 in combination with the unloading 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 retreating section. In this process, the auxiliary rod 29 is pushed to carry the cylindrical rack 210 to move upward for the second time, and the push column 53 is again inserted into the corresponding nut receiving seat 33 and the gasket placement assembly 4.

[0055] While the upper push block 216 rises, the guide pin 217 on the lower push block 216 enters the oblique guide section on the other side from the horizontal assembly section 1, and combines with the other end of the guide pin 217 on the lower push block 216 and 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 bolts, 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] The outer wall of the rotating tube 31 is symmetrically provided with mounting grooves 38 for mounting the bending plate 41, and the two sides of the mounting grooves 38 are symmetrically fixedly connected with pins, the gasket placement assembly 4 comprises a bending plate 41 rotatably connected to the pin, a contact rod 42 is fixedly connected to one side of the bending plate 41 and located in the mounting groove 38, a gasket receiving seat 43 is detachably connected to the free end of the bending plate 41, a torsion spring 44 is fixedly connected between the bending plate 41 and the mounting groove 38 and located on the outer side of the pin, and an annular giving way 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 that the gasket is effectively received. 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 corresponding gasket receiving seats 43 as the rotation axis, so that the nut rising below is prompted to pass between the two groups of gasket receiving seats 43, thereby avoiding the gasket receiving seat 43 from interfering with the rising assembly of the nut.

[0058] Example 2: Please refer to Figure 6 and Fig. 9As shown, in this embodiment, a plurality of slide grooves 56 are equidistantly provided on the annular outer wall of the push column 53, and a positioning rod 57 is slidably connected inside the slide groove 56, and a spring 58 is fixedly connected between the bottom of the positioning rod 57 and the slide groove 56. By arranging a plurality of groups of positioning rods 57 on the push column 53, when the push column 53 rises, the plurality of groups of positioning rods 57 are passed through the inside of the nut and the gasket, thereby realizing the positioning coincidence of the nut and the gasket and the central axis of the non-standard bolt, so as to improve the assembly accuracy of the non-standard fastener;

[0059] The slide groove 56 and spring 58 are provided 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 with the limit blocks, and the inner wall of the slide groove 56 is provided with a limit groove slidably connected with the corresponding limit block, so as to improve the stability of the linear motion of the positioning rod 57.

[0060] A second slide groove 59 is provided at the top of the positioning rod 57, and a trapezoidal guide block 510 is slidably connected inside the second slide groove 59, and a second spring 511 is fixedly connected between the bottom of the trapezoidal guide block 510 and the second slide groove 59. The trapezoidal guide block 510 provided on the corresponding positioning rod 57 is used to guide the gasket and nut offset on the receiving seat, so that multiple groups of positioning rods 57 are smoothly inserted into the gasket and nut, and the second slide groove 59 cooperates with the second spring 511;

[0061] Compared with directly setting a guiding 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, and an anti-slip pattern is provided on the top of the abutment ring 512 to prevent the nut contacting the non-standard bolt from rotating with the guide, and an L-shaped rod 513 is fixedly connected to the bottom of the abutment ring 512 and located between two adjacent positioning rods 57, and a sliding groove 514 slidably connected to the corresponding L-shaped rod 513 is provided on the annular outer wall of the push column 53, and a spring 515 is fixedly connected between the bottom of the L-shaped rod 513 and the sliding 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 implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
