Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0031] In some embodiments, please refer to the attached instructions. Figure 1-7 , a hardware continuous assembly device, comprising a base 10, a first indexing plate 20, a second indexing plate 30 and an assembly mechanism 40;

[0032] The left and right sides of the top of the base 10 are rotatably mounted with a dividing plate 1 20 and a dividing plate 2 30. The outer edge of the dividing plate 1 20 is uniformly provided with a plurality of grooves 1 21 for matching nuts 50 in a circular array, and a groove 22 for matching bolts 51 is provided at the bottom of the groove 1 21. The outer edge of the dividing plate 2 30 is uniformly provided with a plurality of grooves 31 for matching bolts 51 in a circular array. The dividing plate 2 30 is located on the upper side of the dividing plate 1 20, and the movement trajectory of the groove 3 31 is tangent to the movement trajectory of the groove 2 22.

[0033] The indexing plate 1 20 and the indexing plate 2 30 rotate synchronously in opposite directions, the indexing plate 1 20 rotates clockwise, and the indexing plate 2 30 rotates counterclockwise, the indexing plate 1 20 rotates a distance of a groove 1 21 each time, and the indexing plate 2 30 rotates a distance of a groove 3 31 each time;

[0034] The assembly mechanism 40 includes a vertical moving assembly and a press-fit assembly. The vertical moving assembly is arranged on the top of the base 10 and located at the rear side of the indexing plate 1 20. The moving end of the vertical moving assembly is equipped with a plurality of press-fit assemblies corresponding to the groove 1 21. The height of the press-fit assembly is gradually reduced along the movement trajectory of the nut 50, and is used to tighten the bolt 51 in stages.

[0035] The side of the indexing plate 20 is provided with a circular outer stopper 23 that fits with the groove 21 and is used to prevent the nut 50 from sliding out of the groove 21; the outer stopper 23 is provided with a notch for the bolt 51 to feed and discharge from the indexing plate 20;

[0036] An inner stopper 24 and an outer stopper 25 are respectively provided on the inner side and the outer side of the upper end of the indexing plate 1 20. A protrusion is provided on the inner stopper 24 to block the bolt 51 in the groove 1 21, so that the finished product slides out of the indexing plate 1 20 along the protrusion; the outer stopper 1 23 and the inner stopper 24 are both fixedly connected to the base 10, and the outer stopper 25 is fixedly installed on the upper side of the outer stopper 1 23;

[0037] A limiting movable groove is formed between the outer stopper 25 and the inner stopper 24, which is used to limit the bolt 51 of the workpiece after assembly;

[0038] The feed end of the outer stopper 23 is provided with a rounded corner for guiding the material. The outer stopper 23 and the groove 21 cooperate to hold and fix the nut 50 to prevent the nut 50 from rotating when the indexing plate 20 stops rotating, so that the bolt 51 can rotate relative to the nut 50.

[0039] The outer edge of the second indexing plate 30 is provided with a fan-shaped side stopper 32 that fits the second indexing plate 30 and is used to prevent the bolt 51 from sliding out of the third groove 31;

[0040] The feed end of the side block 32 is provided with a rounded corner for guiding the material;

[0041] A bottom stopper 33 is provided at the bottom of the dividing plate 2 30 , and a slope for pushing the bolt 51 is provided at the top of the bottom stopper 33 , and the highest point of the bottom stopper 33 is flush with the dividing plate 1 20 ;

[0042] The side stopper 32 and the bottom stopper 33 are both fixedly connected to the base 10 .

[0043] In the present invention, the nut 50 and the bolt 51 can be fed by a linear feeder, the nut is transferred to the groove 1 21 of the indexing plate 1 20, the bolt 51 is inserted into the groove 3 31 of the indexing plate 2 30, and the bolt head of the bolt 51 is clamped on the upper end surface of the indexing plate 2 30;

[0044] Then, the indexing plate 1 20 and the indexing plate 2 30 rotate, and the lower end of the bolt 51 is gradually lifted up by the bottom stopper 33 during the movement of the bolt 51, until the lower end of the bolt 51 is flush with the upper end surface of the indexing plate 1 20;

[0045] When the groove 1 21 and the groove 3 31 are aligned, the bolt 51 in the groove 3 31 is aligned with the screw hole of the nut 50 in the groove 1 21, and the bolt 51 falls into the nut 50; the vertical moving assembly drives the press-fitting assembly to move downward, and after supporting the bolt 51, drives the bolt 51 to rotate, so that the bolt 51 is screwed into the nut 50 to a certain depth, and at this time, the lower end of the bolt 51 passes through the nut 50 and extends into the groove 2 22;

[0046] Then, the indexing plate 1 20 and the indexing plate 2 30 continue to rotate, and the bolt 51 moves with the nut 50. The bolt 51 disengages from the groove 31 and separates from the indexing plate 2 30. The bolt 51 moves in the limiting movable groove, and the next group of press-fitting components continues to rotate the bolt 51, so that the depth of the bolt 51 screwed into the nut 50 increases, and with the cooperation of several groups of press-fitting components, the bolt 51 is rotated step by step to complete the assembly operation of the bolt 51 and the nut 50. The assembly efficiency is high, the assembly effect is stable, and the continuous assembly operation of the bolt 51 and the nut 50 is realized, so that the equipment is suitable for batch assembly operations of bolts 51 and nuts 50.

[0047] The vertical moving assembly includes a vertical plate 41, a driving motor 42, a screw 43, a linear slide 44 and a moving plate 45. The vertical plate 41 and the driving motor 42 are fixedly connected to the base 10. The linear slide 44 is symmetrically fixedly installed on both sides of the vertical plate 41. The output end of the driving motor 42 is fixedly connected to one end of the screw 43, and the other end of the screw 43 is rotatably connected to the vertical plate 41 through a bearing; the moving plate 45 is limitedly slidably connected to the linear slide 44 through a slider and is threadedly connected to the screw 43 through a threaded sleeve;

[0048] The press assembly includes a rotating motor 46 and a pressure plate 47. The housing of the rotating motor 46 is fixedly connected to the moving plate 45. The output end of the rotating motor 46 is fixedly connected to the pressure plate 47. The lower end of the pressure plate 47 is provided with an anti-skid layer for increasing friction. The anti-skid layer can be made of rubber.

[0049] The rotating motor 46 of the assembly assembly is fixedly connected to the moving plate 45 through a spacer, and the height of the pressure plate 47 gradually decreases along the movement trajectory of the nut 50.

[0050] The screw rod 43 is driven by the driving motor 42 to rotate, so that the movable plate 45 moves vertically downward under the limiting action of the linear slide rail 44 until the pressure plate 47 abuts against the head of the bolt 51. At this time, the nut 50 is held by the groove 21 and the outer stopper 23. The rotating motor 46 drives the pressure plate 47 to rotate, so that the pressure plate 47 drives the bolt 51 to rotate and screw into the nut 50, and under the drive of the driving motor 42 and the screw rod 43, the pressure plate 47 moves downward with the downward movement of the bolt 51, and the spinning effect of the pressure plate 47 on the bolt 51 is always maintained. When the bolt 51 is screwed into the nut 50 to a set depth, the movable plate 45 drives the pressure plate 47 to reset, so that the workpiece moves to the bottom of the next pressure plate 47, and the assembly work of the bolt 51 and the nut 50 is repeated until the insertion depth of the nut 50 and the bolt 51 meets the set value. The assembly stability of the bolt 51 and the nut 50 is ensured through multi-stage spinning operations.

[0051] 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 aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
