DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Embodiment 1

[0029] Reference Figure 1-6 A pre-positioned vehicle door lock assembly rivet device, comprising a workstation 1 and a workbench 2 arranged inside the workstation 1, characterized in that: a left-right symmetrical model frame 3 is distributed on the upper end of the workbench 2, and a plurality of rivet holes 4 of different sizes are opened on the model frame 3, a support frame 5 is arranged on the upper end of the model frame 3, and a plurality of pipes 6 are fixedly arranged on the support frame 5, a push plate 7 is slidably arranged on the pipe 6, a hydraulic cylinder 12 is arranged at the lower end of the push plate 7, a clamping assembly 8 is arranged at the intersection of the push plate 7 and the pipe 6, a discharge assembly 9 is arranged at the lower end of the pipe 6, and the discharge assembly 9 is used to loosen and drop the rivets clamped in the pipe 6, a material receiving assembly 10 is arranged at the upper end of the pipe 6, and an intermittent feeding assembly 11 is arranged at the rear end of the material receiving assembly 10.

[0030] Reference Figure 6 The clamping assembly 8 includes a rectangular groove 81 arranged on the lower end surface of the pushing plate 7 and located on both sides of the pipe 6, a triangular pushing block a82 slidably arranged in the rectangular groove 81, and a return spring 83 fixedly arranged at the rear end of the triangular pushing block a82, and the other end of the return spring 83 is fixedly arranged on the inner wall of the rectangular groove 81.

[0031] It is worth mentioning here that the triangular push blocks a82 arranged on both sides of the pipe 6 can clamp the fallen rivets, and the rivets can be driven downward by the push plate 7, which reduces the path of the rivets falling and avoids the occurrence of rivets falling and dislocation at high positions.

[0032] Reference Figure 6 The discharge assembly 9 includes through grooves 91 arranged on both sides of the pipeline 6 and a triangular push block b92 fixedly arranged at the lower end of the through groove 91.

[0033] In this embodiment, the triangular push block a82 is squeezed by the triangular push block b92, and the triangular push block a82 is squeezed toward the return springs 83 on both sides, so that the rivet releases the limit of the clamping assembly 8, which is conducive to the rivet falling into the rivet hole 4 without misalignment.

[0034] Reference Figure 6 The widths of the through slot 91, the triangular push block a82 and the triangular push block b92 are consistent, and the inclinations of the inclined surfaces of the triangular push block a82 and the triangular push block b92 are consistent.

[0035] Reference Figure 4-5 The material receiving assembly 10 includes a fixing frame 101 arranged on the upper end surface of the supporting frame 5, a through hole 102 arranged in the middle of the fixing frame 101 and communicating with the pipeline 6, an expansion port 103 arranged at the upper end of the through hole 102, a guide plate 104 arranged at the upper end of the expansion port 103, and a feeding pipe 105 arranged on the side of the fixing frame 101.

[0036] It is worth mentioning here that the guide plate 104 can serve as a guide seat for the rivets dropped into the feeding tube 105 , and the expansion opening 103 can facilitate the rivets to drop into the through hole 102 .

[0037] Reference Figure 4-5 The intermittent feeding assembly 11 includes a rotating shaft 111 rotatably arranged on the side of the fixed frame 101 and located below the feeding pipe 105, a notch 112 arranged below the feeding pipe 105, an isolation piece a113 and an isolation piece b114 arranged on the rotating shaft 111 and distributed in parallel, a gear 115 arranged at the rear end of the rotating shaft 111, and a rack 116 arranged on the pushing plate 7 and meshing with the gear 115.

[0038] In this embodiment, the rear end of the feed tube 105 for conveying rivets of the same size is connected to the same multi-station vibration plate, and the rear end of the feed tube 105 for conveying rivets of different sizes is connected to a vibration plate of corresponding size for rivet conveying.

[0039] Reference Figure 5A circle of protrusions 117 is provided on one side of the isolation piece a113, the center of the protrusions 117 is consistent with the center of the isolation piece a113, the protrusions 117 are set to be half of the isolation piece a113, and the structure of the isolation piece b114 is consistent with that of the isolation piece a113.

[0040] In this embodiment, by providing the isolation sheet a113 and the isolation sheet b114, the falling of the rivet is limited twice, thereby realizing the single cutting of the rivet.

[0041] Reference Figure 5 The isolation piece a113 and the isolation piece b114 are both rotatably set in the slot 112, the outer circles of the protrusions 117 on the isolation piece a113 and the isolation piece b114 are rotatably set inside the feeding tube 105, and the outer circles of the isolation piece a113 and the isolation piece b114 are rotatably set at the slot 112.

[0042] It is worth mentioning here that the protrusions 117 on the isolation pieces a113 and b114 limit the rivets, and the distance between the isolation pieces a113 and b114 can only accommodate the length of one rivet, so that each movement of the pushing plate 7 can push one rivet down.

[0043] The working process is as follows

[0044] The hydraulic cylinder 12 drives the push plate 7 to move up and down on the pipe 6, and the rack 116 on the push plate 7 rises and meshes with the gear 115, driving the rotating shaft 111 to rotate, thereby driving the isolation piece a113 and the isolation piece b114 to rotate;

[0045] The vibration plate conveys the arranged rivets to the feeding tube 105. Through the blocking effect of the isolation sheet a113 and the isolation sheet b114, there is only one rivet between the isolation sheet a113 and the isolation sheet b114. When the rivet falls from the feeding tube 105, it is guided by the guide plate 104 and enters the through hole 102.

[0046] When the rivet falls straight down in the through hole 102, the triangular push block a82 inside the push plate 7 at the upper end of the pipe 6 will clamp the rivet. The push plate 7 descends on the pipe 6 under the push of the hydraulic cylinder 12, and the triangular push block b92 squeezes the triangular push block a82, driving the triangular push block a82 to squeeze the return spring 83 in the rectangular groove 81. After the rivet is not restricted, it falls straight down from the inside of the pipe 6 to the rivet hole 4, completing the preliminary placement process of the rivet.

[0047] Of course, in the present technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0048] 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.
