Technical Field

[0001] The invention relates to the field of ball stud assembly, and in particular to a precise combined assembly device for ball stud pin parts. Background Art

[0002] The production of ball studs involves the assembly of a ball seat, ball head, bottom cover, and housing. This involves numerous parts, and the accuracy of the mating between the ball head and seat directly impacts the performance of the finished product. Currently, the seat and head are typically manually mated, followed by assembly using equipment such as presses and riveters. This manual approach to mating the seat and head is inefficient and cannot meet the requirements of high-volume production.

[0003] In view of the above problems, the present invention provides a precise assembly device for ball stud parts to solve the above problems. Summary of the Invention

[0006] a ball joint mechanism, fixed to the load frame and connected to the motor via a belt; and

[0007] The ball seat clamping mechanism is fixed on the load frame and can cooperate with the ball head docking mechanism to complete the precise docking assembly of the ball head and the ball seat.

[0008] Furthermore, preferably, the ball socket clamping mechanism can clamp and move the ball socket according to the docking state of the ball head in the ball head docking mechanism during operation, and this movement state includes movement along the X-axis direction, the Y-axis direction and the Z-axis direction.

[0017] Further, preferably, the clamping belt includes:

[0018] A belt is sleeved on the double-groove pulley and the single-groove pulley, and a plurality of sliding grooves are opened around the circumference of the belt; and

[0019] The second chute is arranged in two and is symmetrically opened on the belt with the first chute as the symmetry point.

[0020] Furthermore, preferably, the stabilization controller includes:

[0021] A slide rod is slidably arranged on the second slide groove, and a clamping groove is fixed between the two slide rods;

[0025] Compared with the prior art, the present invention provides a precise assembly device for ball stud parts, which has the following beneficial effects:

[0026] In the present invention, the ball head docking mechanism uses gravity to adjust the ball head so that it is in a docking state, and then the stabilizing controller clamps and fixes the ball head to avoid shaking due to contact when the ball head is docked with the ball seat, which causes the ball head and the sphere to fail to be assembled, thereby effectively improving the docking accuracy of the ball head and the ball seat.

[0027] After the docking is completed, the ball seat clamping mechanism controls the stability controller to release the self-locking state and restore the stability controller to the initial state, so as to clamp and fix the ball head in the next stage, thereby improving the docking efficiency of the ball head and the ball seat.

[0033] Reference Figures 1 to 4 The present invention provides a technical solution: a precise assembly device for ball stud parts, comprising:

[0034] A load carrier 1, on which a motor 2 is fixed;

[0035] A ball joint mechanism 3 is fixed to the load frame 1 and connected to the motor 2 via a belt; and

[0036] The ball seat clamping mechanism 4 is fixed on the load frame 1 and can cooperate with the ball head docking mechanism 3 to complete the precise docking and assembly of the ball head and the ball seat.

[0037] As a preferred embodiment, the ball seat clamping mechanism 4 can clamp and move the ball seat according to the ball head docking state in the ball head docking mechanism 3 during operation, and this movement state includes movement along the X-axis direction, the Y-axis direction and the Z-axis direction.

[0038] As a preferred embodiment, the ball joint mechanism 3 includes:

[0039] A fixing plate 31 is fixed to the load frame 1, and a mounting frame 1 32 and a mounting frame 2 33 are symmetrically fixed to the fixing plate 31, and an L-shaped frame plate 34 is fixed to the mounting frame 2 33;

[0040] A double-groove pulley 35 is rotatably mounted on the mounting frame 1 32 and connected to the motor 2 via a belt;

[0041] A single groove pulley 36 is rotatably mounted on the L-shaped frame plate 34;

[0042] The cylindrical pulley 38 is coaxially fixed on the double-groove pulley 35 and the single-groove pulley 36;

[0043] A cylindrical conveyor belt 37 is sleeved on the cylindrical pulley 38;

[0044] A clamping belt 39 is sleeved on the double-groove pulley 35 and the single-groove pulley 36, and a plurality of stabilizing controllers 5 are evenly arranged on the clamping belt 39; and

[0045] The telescopic rod 310 is fixed on the second mounting frame 33 and can control the stabilizing controller 5 to stably clamp the ball head.

[0046] It should be noted that when the motor 2 starts running, the double-groove pulley 35 and the cylindrical pulley 38 will start to rotate through the belt transmission, and the single-groove pulley 36 will rotate synchronously through the clamping belt 39. At this time, the feed belt will first transport the ball head between the two cylindrical conveyor belts 37. Under the action of gravity, the ball head will adjust its direction by itself, and finally the spherical part of the ball head will be located between the two cylindrical conveyor belts 37, and the ball rod part will be in a vertical state relative to the ground; when the ball head is transported to the area of ​​the mounting frame 2 33 under the action of the cylindrical conveyor belt 37, the telescopic rod 310 pushes the stabilizing controller 5 on the clamping belts 39 on both sides to clamp the spherical part of the ball head, thereby preventing the ball head from shaking due to contact when docking with the ball seat, resulting in failure of assembly of the ball head and the ball, and effectively improving the docking accuracy of the ball head and the ball seat.

[0047] It needs to be explained that after the telescopic rod 310 pushes the stabilization controller 5 to complete the clamping and fixing of the ball, it will form a self-locking state to avoid clamping failure, and after the ball seat clamping mechanism 4 completes the docking of the ball and the ball seat, this self-locking state will be released under the action of the ball seat clamping mechanism 4 and restored to its initial state, so as to facilitate the next clamping and fixing of the ball head, thereby greatly improving the efficiency of the precise docking of the ball head and ball seat.

[0048] As a preferred embodiment, the clamping belt 39 includes:

[0049] A belt 391 is sleeved on the double-groove pulley 35 and the single-groove pulley 36, and a plurality of sliding grooves 392 are formed around the circumference of the belt 391; and

[0050] The second chute 393 is arranged in two and is symmetrically opened on the belt 391 with the first chute 392 as the symmetrical point.

[0051] As a preferred embodiment, the stability controller 5 includes:

[0052] A slide rod 51 is slidably disposed on the second slide groove 393 , and a clamping groove 54 is fixed between the two slide rods 51 ;

[0053] A rack 52 is fixed on the slide bar 51, and the teeth of the rack 52 are inclined;

[0054] A top platform 53 is slidably mounted in the first slide groove 392 and connected to the inner wall of the first slide groove 392 via a compression spring 56. The top platform 53 is fixed to the slide rod 51; and

[0055] The limiting claw buckle 55 is rotatably arranged in the second slide groove 393 and can limit the position of the slide rod 51 through the rack 52. A torsion spring is provided at the rotating connection of the limiting claw buckle 55.

[0056] It should be noted that when the telescopic rod 310 pushes the top platform 53, the compression spring 56 will be compressed, and the slide rod 51 will slide toward the ball head in the slide groove 2 393, that is, the clamping grooves 54 on both sides of the ball head will clamp and fix the spherical part of the ball head; while the slide rod 51 slides toward the ball head, the restricted positioning of the rack 52 and the limit claw buckle 55 will prevent the slide rod 51 from rebounding due to the elastic force of the compression spring 56 and other external forces, thereby causing the clamping groove 54 to fail to clamp the ball head, preventing the ball head from contacting and colliding with the ball seat during docking, thereby affecting its docking effect, and effectively improving the docking accuracy of the ball head and the ball seat.

[0057] It should be noted that after the ball seat clamping mechanism 4 controls the ball seat to complete the docking with the ball head, the ball seat clamping mechanism 4 continues to move slightly in the Y-axis direction. At this time, the ball will drive the clamping groove 54 to move upward. The movement of the clamping groove 54 will cause the slide bar 51 to slide upward in the slide groove 392. This sliding will cause the rack 52 to disengage from the limiting claw 55. At this time, under the action of the compression spring 56, the top platform 53 and the slide bar 51 will quickly return to their initial state, so as to clamp and fix the ball head in the next stage, thereby improving the docking efficiency of the ball head and the ball seat.

[0058] During specific implementation, the ball head is transported to the cylindrical conveyor belt 37 through the feed belt, and under the action of gravity, the ball heads will be neatly arranged to the docking state. When the ball head arrives at the mounting frame 2 33, the stability controller 5 will clamp and fix the ball body of the ball head and automatically lock it. When the ball head arrives at the docking area, the ball seat clamping mechanism 4 will enable the ball seat and the ball to complete precise docking. After the docking is completed, the ball seat clamping mechanism 4 controls the stability controller 5 to release the self-locking state. Finally, the ball seat clamping mechanism 4 removes the ball head and ball seat after docking to enter the next assembly link.

[0059] The above 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 this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
