Description

Technical Field

[0001] This invention relates to the field of vehicle door lock technology, specifically to a pre-positioning vehicle door lock assembly riveting device. Background Technology

[0002] Car door locks are designed to enhance convenience and safety by providing centralized control over the locking and unlocking of all four doors. In recent years, the demand for car door locks in my country has been steadily increasing, with the gradual growth in automobile production and sales providing significant growth potential for the car lock market.

[0003] In a Chinese invention patent with publication number CN108160902A, a prior art document proposes a rivet positioning device for producing clutch disc assemblies. Specifically, it proposes "a rivet feeding vibratory plate and a gripping mechanism, an outer barrel, a hollow column and a positioning plate. The positioning plate is provided with positioning holes for positioning rivets. The upper end of the hollow column is provided with a through hole corresponding to the positioning hole. An elastic conveying plate is hinged to the outer barrel. The conveying plate is provided with a sliding groove that extends to the through hole. The feeding track of the rivet feeding vibratory plate is connected to the sliding groove on the conveying plate. The gripping mechanism is located above the outer barrel and is provided with a suction nozzle corresponding to the through hole. The gripping mechanism is also provided with a pressing rod that presses the hollow column downward."

[0004] In a prior art Chinese invention patent with publication number CN107983900A, a rivet rapid material distribution and positioning device was proposed. Specifically, it was proposed that "a mounting base is provided, a motor is provided on the mounting base, the motor is connected to a gearbox, a rotating disk is provided above the mounting base, the rotating disk is connected to the output end of the gearbox, a material distribution ratchet is fixedly installed on the rotating disk, a fixed sleeve is sleeved on the outside of the rotating disk, the fixed sleeve is fixedly connected to the mounting base, a contour fixing ring is installed above the fixed sleeve, a radial rivet channel is provided on the contour fixing ring, inverted rivets are arranged in sequence in the rivet channel, and the rivets in the rivet channel are conveyed radially toward the material distribution ratchet through a conveying unit."

[0005] The aforementioned prior art also has the following drawbacks: The inventors found that the rivets in the devices of prior art 1 and 2 can only be of one type, resulting in low work efficiency and low practicality, and cannot meet the requirement of installing multiple rivets at the same time. Therefore, we propose a rivet mounting device for pre-positioning vehicle door lock assembly. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies. This invention features symmetrically arranged model frames on the upper end of a workbench, each with several rivet holes of varying sizes. A support frame is located at the upper end of the model frames, and several pipes are fixedly mounted on the support frame. Push plates slide along the pipes, and a snap-fit ​​assembly is located at the intersection of the push plates and the pipes. A feeding assembly is located at the lower end of the pipes to release the snapped rivets inside the pipes. A receiving assembly is located at the upper end of the pipes, and an intermittent feeding assembly is located at the rear end of the receiving assembly. This invention, by providing several pipes on the support frame corresponding to the rivet holes, achieves batch feeding of rivets of different sizes, avoiding the need for multiple installation processes for rivets of different sizes in conventional devices. Through the coordinated operation of the intermittent feeding assembly, receiving assembly, snap-fit ​​assembly, and feeding assembly, this invention achieves automated single rivet feeding, improving the automation level of the device and increasing the efficiency of vehicle lock assembly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1

[0029] Reference Figure 1-6 A riveting device for assembling a pre-positioned vehicle door lock includes a workstation 1 and a workbench 2 located inside the workstation 1. The workbench 2 is characterized by: symmetrically arranged model frames 3 on the upper part of the workbench 2; several rivet holes 4 of varying sizes on the model frames 3; a support frame 5 at the upper part of the model frames 3; several pipes 6 fixedly mounted on the support frame 5; a pusher plate 7 slidably mounted on the pipes 6; a hydraulic cylinder 12 at the lower end of the pusher plate 7; a snap-fit ​​assembly 8 at the intersection of the pusher plate 7 and the pipes 6; a material feeding assembly 9 at the lower end of the pipes 6 for loosening and releasing the snapped rivets inside the pipes 6; a receiving assembly 10 at the upper end of the pipes 6; and an intermittent feeding assembly 11 at the rear end of the receiving assembly 10.

[0030] Reference Figure 6 The snap-fit ​​assembly 8 includes a rectangular groove 81 disposed on the lower end face of the push plate 7 and located on both sides of the pipe 6, a triangular push block a82 slidably disposed in the rectangular groove 81, and a reset spring 83 fixedly disposed at the rear end of the triangular push block a82. The other end of the reset spring 83 is fixedly disposed on the inner wall of the rectangular groove 81.

[0031] It is worth mentioning that the triangular push blocks a82 set on both sides of the pipe 6 can catch the falling rivets, and the push plate 7 drives the rivets to move downwards, reducing the path of the falling rivets and preventing the rivets from falling from a high position and becoming misaligned.

[0032] Reference Figure 6 The material feeding assembly 9 includes through grooves 91 disposed on both sides of the pipe 6 and a triangular push block b92 fixedly disposed at the lower end of the through grooves 91.

[0033] In this embodiment, the triangular pusher block b92 presses against the triangular pusher block a82, and the triangular pusher block a82 presses against the reset springs 83 on both sides, so that the rivet is released from the limit of the locking assembly 8, which is conducive to the rivet falling into the rivet hole 4 and will not cause misalignment.

[0034] Reference Figure 6 The widths of the through groove 91, the triangular push block a82, and the triangular push block b92 are the same, and the slopes of the triangular push block a82 and the triangular push block b92 are the same.

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

[0036] It is worth mentioning that the guide plate 104 can act as a guide for rivets falling into the feed tube 105, and the expansion port 103 facilitates the rivets falling into the through hole 102.

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

[0038] In this embodiment, the rear end of the feeding pipe 105 for conveying rivets of the same size is connected to the same multi-station vibratory feeder, and the rear end of the feeding pipe 105 for conveying rivets of different sizes is connected to a vibratory feeder of the corresponding size for rivet conveying.

[0039] Reference Figure 5The insulating sheet a113 has a ring of protrusions 117 on one side, the center of the protrusions 117 is the same as the center of the insulating sheet a113, and the protrusions 117 are set as half of the insulating sheet a113. The structure of the insulating sheet b114 is the same as that of the insulating sheet a113.

[0040] In this embodiment, the isolation plates a113 and b114 provide two-fold restraint on the rivet falling off, thus enabling the individual cutting of the rivet.

[0041] Reference Figure 5 The insulating sheet a113 and the insulating sheet b114 are both rotatably disposed in the slot 112. The outer ring of the protrusion 117 on the insulating sheet a113 and the insulating sheet b114 is rotatably disposed inside the feeding pipe 105. The outer ring of the insulating sheet a113 and the insulating sheet b114 is rotatably disposed at the slot 112.

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

[0043] The work process is as follows:

[0044] The hydraulic cylinder 12 drives the push plate 7 to move up and down on the pipe 6. The rack 116 on the push plate 7 rises and meshes with the gear 115, driving the rotating shaft 111 to rotate, which in turn drives the insulating sheet a113 and the insulating sheet b114 to rotate.

[0045] The vibratory feeder transports the arranged rivets into the feed tube 105. Due to the blocking effect of the insulating plate a113 and the insulating plate b114, there is only one rivet between the insulating plate a113 and the insulating plate b114. When the rivet falls into the feed tube 105, it is guided by the guide plate 104 and enters the through hole 102.

[0046] When the rivet falls straight down through the through hole 102, the triangular push block a82 inside the push plate 7 at the upper end of the pipe 6 will hold the rivet in place. The push plate 7 descends on the pipe 6 under the push of the hydraulic cylinder 12. The triangular push block b92 squeezes the triangular push block a82, causing the triangular push block a82 to squeeze the return spring 83 in the rectangular groove 81. After the rivet is no longer restricted, it falls straight down through the pipe 6 into the rivet hole 4, completing the initial placement process of the rivet.

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

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
