Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1 to 7This utility model provides an auxiliary installation device for rivets used in thin plate fastening connections, including a screening disc 1, a supporting disc 2, and an auxiliary disc 3. The screening disc 1 has screening holes 4, and the supporting disc 2 has external threads 5 on its outer side. A connecting block 6 is provided on the outer side of the auxiliary disc 3, and a connecting ring 7 is rotatably disposed below the connecting block 6. A first disc 8 is provided on one side of the connecting ring 7, and a magnetic suction piece 9 is provided on the first disc 8, with the magnetic suction piece 9 located directly below the auxiliary disc 3. The other side of the connecting ring 7... A second disc 10 is provided, on which a lifting component 11 is provided. A handle 12 is provided on the connecting block 6. The inner side of the auxiliary disc 3 has an internal thread 13. The inner side of the auxiliary disc 3 is provided with a lifting ring 14. The screening disc 1 is slidably connected to the auxiliary disc 3 and is located inside the auxiliary disc 3 and also on the lifting ring 14. The abutting disc 2 is threaded on the inner side of the auxiliary disc 3 and abuts against the screening disc 1. The external thread 5 is located at the internal thread 13.

[0023] In this embodiment, the rivets are initially screened through the screening holes 4 on the screening disc 1, guiding them into the disc in a certain posture to prepare for subsequent correct installation. The external thread 5 on the outer side of the supporting disc 2 engages with the internal thread 13 on the inner side of the auxiliary disc 3, allowing the supporting disc 2 to be threaded onto the inner side of the auxiliary disc 3 and abut against the screening disc 1. This adjustable abutment method can stably fix the screening disc 1, ensuring the stable position of the rivets in the screening holes 4 and preventing rivet position displacement during operation. It also facilitates the replacement of the screening disc 1 with screening holes 4 of different diameters. This device is suitable for screening different types of rivets. The connecting ring 7 allows the first disc 8 and the second disc 10 to rotate flexibly, making it convenient for operators to adjust the angle as needed. The magnetic plate 9 can attract rivets in the correct position within the screening hole 4, ensuring that the rivet head faces upwards, so that when additional rivets are removed from the auxiliary disc 3, the screened rivets will not fall out. The lifting component 11 can lift the rivets attracted to the magnetic plate 9, making it convenient for operators to pick up and install them. The handle 12 on the connecting block 6 allows operators to hold the entire device for operation, improving the convenience and flexibility of operation.

[0024] Furthermore, there are multiple screening holes 4, and each of the multiple screening holes 4 has a guide slope 15.

[0025] In this embodiment, multiple rivets can be batch-screened, which greatly improves the screening efficiency and meets the rapid screening needs in scenarios where multiple rivets need to be densely arranged. The setting of the guide slope 15 can better guide the rivet shank into the screening hole 4, increase the probability that the rivet enters the screening hole 4 in the correct posture, reduce the need to adjust the rivet's position afterward, further save operation time, and improve installation efficiency.

[0026] Furthermore, the lifting assembly 11 includes a lifting plate 16, a lifting screw 17, and a threaded sleeve 18. A fixed seat 19 is provided below the second disc 10, and a circular groove 20 is provided above the second disc 10. The lifting plate 16 is fixedly connected to the lifting screw 17 and is located on the lifting screw 17, and the lifting plate 16 is also located in the circular groove 20. The lifting screw 17 is threadedly connected to the threaded sleeve 18 and is located in the threaded sleeve 18, and also penetrates the second disc 10. The threaded sleeve 18 is rotatably connected to the fixed seat 19 through a positioning ring and is located in the fixed seat 19.

[0027] In this embodiment, when the threaded sleeve 18 is rotated, the lifting screw 17 moves up and down within the threaded sleeve 18, thereby driving the lifting plate 16, which is fixedly connected to the lifting screw 17, to move up and down within the circular groove 20. This design allows the operator to precisely control the lifting and lowering of the lifting plate 16 by rotating the threaded sleeve 18, thereby enabling the operator to smoothly and accurately lift multiple rivets, facilitating the operator's handling and installation, and improving the accuracy and convenience of the operation.

[0028] Furthermore, a plurality of positioning rods 21 are provided below the lifting plate 16, and the plurality of positioning rods 21 respectively penetrate the second disk 10.

[0029] In this embodiment, the positioning rod 21 can provide guidance for the lifting plate 16 to rise and fall, ensuring that the lifting plate 16 remains stable during the up and down movement and will not deviate or shake.

[0030] Furthermore, a fixing block 22 is provided on the side of the auxiliary disk 3 away from the connecting block 6. The fixing block 22 has a movable cavity 23. A fixing rod 24 is slidably disposed in the movable cavity 23 and passes through both sides of the fixing block 22. A limit ring 25 and a spring 26 are provided on the fixing rod 24, and the spring 26 abuts between the limit ring 25 and the movable cavity 23. The outer sides of the first disk 8 and the second disk 10 both have fixing holes 27, and the fixing rod 24 can be inserted into the corresponding fixing holes 27.

[0031] In this embodiment, when the operator rotates the connecting ring 7 to bring the first disk 8 or the second disk 10 to a suitable position, the fixing rod 24 will be inserted into the corresponding fixing hole 27 under the action of the spring 26, thereby fixing the first disk 8 or the second disk 10 in that position and preventing it from rotating arbitrarily during operation, thus ensuring the stability and accuracy of the operation. When it is necessary to adjust the position of the first disk 8 or the second disk 10, the operator only needs to pull the fixing rod 24 outward to disengage it from the fixing hole 27, and then rotate the connecting ring 7 again for adjustment. The operation is simple and convenient, improving the practicality and ease of operation of the device.

[0032] This utility model also provides a thin plate fastening connection rivet, and an auxiliary installation device for the thin plate fastening connection rivet, wherein the thin plate fastening connection rivet 28 is a countersunk annular groove rivet.

[0033] In this embodiment, the thin plate fastening rivet 28, during press-fitting, works with the reinforcing plate 29 and the connected sheet metal 31 to achieve riveting of the steel-aluminum structural thin plates, realizing physical interlocking to form a mechanical interlock. At the same time, the reinforcing plate 29 is riveted with the mold, and can work with the reinforcing plate 29 and the thin sheet metal 30 to complete the riveting, achieving a stronger riveting capability. After riveting, a firm bond is formed between the rivet and the material. There is no risk of thermal deformation during the riveting process. The product assembly occupies less space, has a stronger ability to adapt to the usage environment, and has better adaptability to thin plate riveting.

[0034] When using the thin plate fastening connection rivet auxiliary installation device of this embodiment, firstly, place the appropriate screening disc 1 into the auxiliary disc 3 and place it on the lifting ring 14. Rotate the abutment disc 2 so that it engages with the internal thread 13 on the inner side of the auxiliary disc 3 through the external thread 5, abutting the fixed screening disc 1. Pour multiple rivets into the screening disc 1, and hold the handle 12 to shake the auxiliary disc 3 back and forth, so that the rivet rods enter the corresponding screening holes 4 according to the guide slope 15. The rivet rods entering the screening holes 4 will be attracted by the magnetic suction piece 9. When all the screening holes 4 are filled, turn the auxiliary disc 3 over so that the excess rivets fall out of the auxiliary disc 3. When it is necessary to remove the rivets, rotate the connecting ring 7 to rotate the second disc 10 to the appropriate position. At this time, the fixed rod 24. Under the action of the spring 26, the second disc 10 is inserted into the fixing hole 27 and fixed. The threaded sleeve 18 is rotated. Since the threaded sleeve 18 is threadedly connected to the lifting screw 17 and the lifting screw 17 passes through the second disc 10, the lifting screw 17 drives the lifting plate 16 to rise in the circular groove 20. The positioning rod 21 below the lifting plate 16 plays a guiding role, smoothly lifting multiple rivets. The operator can then pick up the rivets for installation. This method effectively solves the technical problem that in scenarios where multiple rivets need to be densely arranged, when installing multiple rivets in sequence manually, it is necessary to ensure that the rivet heads are facing upwards. Since it is impossible to ensure that the rivet heads are facing upwards, the operator needs to repeatedly adjust the positive and negative positions of the rivets, which increases the time consumption and makes it inconvenient to complete the installation quickly.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
