[0032] The embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0033] Please see Figure 1-18 One embodiment of the present invention includes a fastening seat 6 and a fastening nut 9; a fastening device 2 is installed on the outer side of the fastening seat 6, and the fastening bolt 4 of the fastening device 2 is connected to the fastening nut 9 through the fastening seat 6.

[0034] In summary, by using a fastening device base, the installation and docking of the fastening device becomes precise and efficient, reducing labor costs. This enables unmanned, rapid, and automated fastening and assembly of electromechanical products, and is widely applicable to fully automated assembly in various applications such as wing-shaped cargo containers, large equipment, bridge steel frames, robots, automated production lines, and wartime floating bridges. This significantly reduces labor costs and errors, and greatly improves work efficiency and safety.

[0035] The fastening seat 6 also has a push rod 7 parallel to the fastening bolt 4, and a first spring 5 is fitted on the outside of the push rod 7. The first spring 5 is used to push one end of the push rod 7 towards the fastening nut 9. This ensures that after the fastening bolt 4 is unscrewed from the fastening nut 9, the fastening nut 9 is immediately moved away from the hollow guide cone to avoid scratching and damage to the conical surface S1 of the fastening bolt 4 and the internal threaded hole surface S2 of the fastening nut, and the conical surface S3 of the hollow guide cone 8.1 and the guide hole of the fastening nut when the hydraulic cylinder 21 pushes the extension 22 upward.

[0036] The fastening seat 6 is provided with a hollow guide cone 8.1 on the side facing the fastening nut 9, and a solid guide cone 8.2 is provided on one side of the hollow guide cone 8.1. To ensure that when the side beam 19 of the carriage and the flap 22 undergo a certain deformation, the hollow guide cones 8.1 and 8.2, together with the fastening nut hole S4 and the solid cone positioning hole 12, can guide the fastening bolt 4 and the fastening nut 9 to be coaxial and smoothly screwed together.

[0037] After the push rod 7 is ejected by the first spring 5, the height of the push rod 7 exposed outside the fastening seat 6 is greater than the height h of the solid guide cone 8.2. This prevents scratching.

[0038] The hollow guide cone 8.1 is provided with a positioning countersunk hole 13 or a tapered hole 14 and threads 15.1 and 15.2 that engage with the fastening bolt 4. On the one hand, this forces the fastening seat 6 and the fastening nut 9 to gradually align during the fastening operation. On the other hand, it also ensures that the misalignment stress is transferred under bumpy conditions, so as to protect the threads of the fastening bolt 4 and the fastening nut 9 from being damaged, thereby extending their service life.

[0039] The fastening device 2 is also equipped with a drive wheel 11 at the end away from the fastening bolt 4, and the rotation of the drive wheel 11 causes the fastening bolt 4 to connect with the fastening nut 9. By using the drive wheel instead of the motor 1, the control and maintenance are simplified and the failure rate is reduced when fastening at multiple points.

[0040] The fastening nut 9 is also provided with a nut cap 10 on the side away from the fastening seat 6. It is dustproof and waterproof.

[0041] It includes a self-aligning nut sleeve consisting of a second spring 15 and a square nut 16. This is to meet and adapt to the need for calibration when fasteners are severely misaligned and have large displacements under heavy loads.

[0042] It includes a self-aligning nut sleeve consisting of a third spring 24 and a semi-circular nut 17. One end of the semi-circular nut 17 is square. When the fastening bolt 4 is screwed into the semi-circular nut 17, it stops at point X with the nut seat. This reduces the weight of the square nut and lowers the cost.

[0043] Example 1: Specifically, such as Figure 1 As shown, it comprises a fastening seat 6 and a fastening nut 9. The fastening seat is as follows... Figure 4 As shown, the fastening seat 6 is equipped with a push rod 7, and the push rod is equipped with a spring 5, as follows: Figure 4 Figure 5 Figure 6 Figure 7 Figure 9 As shown, a hollow guide cone 8.1 is provided on the fastening seat 6 through the hole of the fastening bolt 4, and a solid guide cone 8.2 is provided on the other side. The fastening device 2 is connected to the fastening seat 6; the fastening nut, as... Figure 11 , Figure 12 , Figure 13 As shown, a positioning countersunk hole 13 or a conical hole 14 and threads 15.1 and 15.2 for engaging with the fastening bolt 4 are provided at the corresponding positions of the hollow guide cone 8.1. A push rod 7 is provided on the fastening seat 6, and a spring 5 is provided on the push rod 7. The push rod is as follows: Figure 4 As shown, the height of the push rod 7 after being ejected by the spring 5 is greater than the height h of the solid guide cone 7. 3 is the output shaft of the fastening device, 1 is the motor of the fastening device, 9 is the nut body, 10 is the nut cover, and 11 is the transmission wheel.

[0044] Example 2: Base of a complete fastening device, wherein the fastening nut includes, for example... Figure 14 The spring 15 and square nut 16 shown form a self-aligning nut sleeve.

[0045] Example 3: Base for a complete set of fastening devices, wherein the fastening nut includes, for example... Figure 15 , Figure 16 As shown, a self-adjusting nut sleeve consisting of a spring 16 and a semi-circular nut 17 is characterized in that: one end of the semi-circular nut 17 is square, and when the fastening bolt 4 is screwed into the semi-circular nut 17, it stops at point X with the nut seat.

[0046] Example 4: Complete fastening device base, its application in a wing-shaped carriage, for example. Figure 17 , Figure 18 As shown, the fastening seat 6 is connected to the side beam 19 of the carriage. When the fastening bolt 4 of the fastening device 2 is unscrewed from the fastening nut 9, the push rod 7, under the action of the spring 5, will push the guide cone 8.1 and the cone of the fastening bolt 4 out of the fastening nut 9. Under the action of the hydraulic cylinder 21, the flap 22 can be safely and reliably deployed. Figure 18 This is a schematic diagram showing the wing 22 after it is lowered and secured to the carriage 20. 18 is the crossbeam at the bottom of the carriage.

[0047] In summary, the unmanned automatic fastening device, with its precisely positioned mounting base, is widely used in the fully automated assembly of electromechanical products, various wing-shaped cargo containers, large equipment, bridge steel frames, robots, automated production lines, wartime floating bridge frames, and other similar applications. This significantly reduces labor costs and errors, and greatly improves work efficiency and safety.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
