[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. Example

[0024] See also Figure 1-Figure 4 As shown, one of the purposes of this embodiment is to provide a hexagonal rivet nut alignment mechanism, including a base 1 and two positioning seats 101 slidably connected to the upper surface of the base 1, the base 1 cooperates with the positioning seats 101 to clamp and fix the hexagonal nut, thereby increasing the stability of the hexagonal nut in the horizontal direction, and positioning mechanisms are provided inside the two positioning seats 101, the positioning mechanisms include a positioning rod 2 fixedly arranged inside the positioning seat 101, and two positioning blocks 202 are slidably connected to the circumferential surface of the positioning rod 2, positioning plates 203 are fixedly arranged on the outer surfaces of the two positioning blocks 202, and limiting plates 204 are fixedly arranged on the tops of the outer surfaces of the two positioning plates 203, the positioning plates 203 and the limiting plates 204 are installed by cooperating with the positioning rod 2 with the positioning blocks 202, so that the positioning plates 203 and the limiting plates 204 can be moved, which can limit the position of the hexagonal nut in the vertical direction, thereby further increasing the stability of the hexagonal nut during use.

[0025] Specifically, the two positioning blocks 202 are fixed with a transmission tooth plate 205 on the surface away from the positioning plate 203, and the positioning seat 101 is rotatably connected with a transmission gear 206 on the middle part of the surface away from the positioning plate 203. The transmission gear 206 is located between the two transmission tooth plates 205, and the two transmission tooth plates 205 are meshed with the transmission gear 206. Hold and pull one of the positioning blocks 202, and when one of the positioning blocks 202 moves, it can drive one of the transmission tooth plates 205 to move, and the transmission gear 206 can drive the other transmission tooth plate 205 and the positioning block 202 to move. A positioning spring 201 is coaxially sleeved on the circumferential surface of the positioning rod 2, and the two ends of the positioning spring 201 are respectively fixed on the inner surface of the positioning seat 101 and the outer surface of the positioning block 202. The positioning block 202 can be driven to move by the elastic force of the positioning spring 201 and the positioning rod 2.

[0026] Furthermore, two mounting rods 102 are fixedly provided inside the base 1, and four moving blocks 104 are slidably connected on the circumferential surfaces of the two mounting rods 102. Two positioning seats 101 are respectively fixedly provided on the tops of the four moving blocks 104. The positioning seat 101 is installed by cooperating with the moving blocks 104 through the mounting rods 102, which can increase the stability of the positioning seat 101 during movement. Four mounting springs 103 are coaxially sleeved on the circumferential surfaces of the two mounting rods 102, and the two ends of the four mounting springs 103 are respectively fixedly provided on the inner surface of the base 1 and the outer surfaces of the four moving blocks 104. Holding and pulling the handle can drive the positioning seat 101 and the moving block 104 to move. When the moving block 104 moves, the mounting spring 103 can be stretched. Loosening the handle can drive the positioning seat 101 and the moving block 104 to move and reset through the elastic force of the mounting spring 103 and the mounting rod 102.

[0027] It is worth mentioning that the inner walls of the base 1 and the positioning seat 101 are both provided with an accordion cover 105, and the two ends of the lower accordion cover 105 are respectively fixed on the inner surface of the base 1 and the outer surfaces of the four moving blocks 104, and the two ends of the upper accordion cover 105 are respectively fixed on the inner surface of the two positioning seats 101 and the outer surfaces of the four positioning blocks 202. The accordion cover 105 can block external dust and prevent dust from entering the base 1 and the positioning seat 101. Two mounting plates 106 are fixed on the outer surface of the base 1. Mounting holes are opened in the two mounting plates 106. The mounting plates 106 are matched with the mounting holes to facilitate the installation of the base 1. Pull rods are fixed in the middle of the upper surfaces of the two positioning seats 101. Holding and pulling the pull rods facilitates pulling the positioning seats 101.

[0028] In summary, the working principle of this solution is as follows: the base 1 is installed by cooperating with the mounting hole through the mounting plate 106, which can increase the stability of the base 1 during use; holding and pulling the handle can drive the positioning seat 101 and the moving block 104 to move; when the moving block 104 moves, the mounting spring 103 can be stretched; the hexagonal nut is placed on the upper surface of the base 1, and the hexagonal nut is located between the two positioning seats 101; the handle is released; the elastic force of the mounting spring 103 cooperates with the mounting rod 102 to drive the positioning seat 101 and the moving block 104 to move and reset, and the hexagonal nut is clamped and fixed, thereby driving the two positioning seats 101 to move closer. The hexagonal nut is moved in the direction of the hexagonal nut to be clamped and fixed, thereby increasing the horizontal stability of the hexagonal nut during the processing. The positioning block 202 can be driven to move by the elastic force of the positioning spring 201 in cooperation with the positioning rod 2, thereby driving the positioning plate 203 and the limit plate 204 to move toward the direction close to the hexagonal nut, limiting the top position of the hexagonal nut to prevent the hexagonal nut from shaking in the vertical direction during the processing, thereby further increasing the stability of the hexagonal nut during the processing. The accordion cover 105 can block external dust to prevent dust from entering the base 1 and the positioning seat 101, thereby affecting the normal use of the alignment mechanism.
