DETAILED DESCRIPTION

[0022] The utility model is described in detail below in conjunction with the accompanying drawings.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] A pressure riveting positioning device for electrical cabinet plugs, such as Figure 1-3 As shown, it includes a lower die base 1 for placing a plug assembly 3, a rivet assembly 2 is provided above the lower die base 1, and the rivet assembly 2 includes a rivet block 21, a rivet rod 22 which can move vertically along the rivet block 21 is provided inside the rivet block 21, and a rivet head 221 is provided at the bottom of the rivet rod 22.

[0025] Specifically, the lower die base 1 can be used to position the plug assembly 3 to prevent the plug assembly 3 from moving during the riveting process, so that the plug assembly 3 can maintain a stable and accurate position during the riveting process, avoid displacement or deformation, and thus ensure the accuracy and consistency of the riveted parts. The plug assembly 3 can be riveted by the riveting assembly 2. During the riveting process, the busbar 31 and the plug 32 are clamped together. The riveting assembly 2 moves downward, and the riveting head 221 presses the exposed part of the upper part of the rivet into a flat shape, and keeps the plugs 32 on both sides in contact with the busbar 31 to complete the connection. In addition, the present riveting positioning device can make the connection between the workpiece and the riveting machine more firm and reliable, avoiding safety issues caused by the displacement of the workpiece.

[0026] As another specific implementation, a vertically penetrating lifting hole 211 is provided inside the rivet block 21, and the rivet rod 22 moves up and down along the lifting hole 211. The lifting hole 211 can facilitate the movement of the rivet rod 22.

[0027] As another specific embodiment, the bottom of the rivet block 21 has a pressure plate 212, and the pressure plate 212 is provided with a guide hole 2121, and the guide hole 2121 is connected to the lifting hole 211. Specifically, the pressure plate 212 first presses the plug 32 and the busbar 31 to prevent the plug assembly 3 from moving, and then guides the rivet through the guide hole 2121, and the rivet head 221 can also be guided through the guide hole 2121. Among them, the size of the bottom of the guide hole 2121 is larger than the size of the rivet head 221 and larger than the size of the rivet rod, so that the rivet head 221 can pass through and accommodate the rivet. At the same time, the degree of deformation of the rivet can be controlled by controlling the size of the bottom of the rivet hole. In this embodiment, the plug assembly 3 is connected by two rivets, and the guide hole 2121 is oblong and can accommodate two rivets.

[0028] As another specific embodiment, a positioning plate 213 is provided on the top of the rivet block 21, and an assembly part 2131 for assembling the rivet block 21 to the rivet machine is provided on the positioning plate 213. The rivet block 21 can be fixed to the rivet machine through the assembly part 2131, and then the rivet rod 22 is connected to the lifting part of the rivet machine, so as to realize the installation of the rivet assembly 2. Among them, the top of the rivet rod 22 is cylindrical, and the middle section of the rivet rod 22 is oblong; the lifting hole 211 has a positioning hole 2132 matching the oblong part of the rivet rod 22, which can guide and circumferentially position the oblong part of the rivet rod 22; in addition, the cylindrical part of the rivet rod 22 cannot pass through the positioning hole 2131, so that the rivet block can be axially positioned.

[0029] As another specific embodiment, an elastic portion 214 is provided in the middle of the rivet block 21. The elastic portion 214 can make the contact between the rivet block 21 and the plug assembly 3 in the vertical direction elastic, so that the plug assembly 3 is evenly stressed, reducing deformation and damage caused by rigid compression.

[0030] As another specific embodiment, the elastic part 214 includes an elastic rubber pad, and a reset spring 215 is connected between the rivet blocks 21 above and below the elastic rubber pad, and the reset spring 215 is arranged on the rivet block 21 through a connecting piece 216. Specifically, the elastic rubber pad can provide elastic force, and the reset spring 215 can further reset the elastic rubber pad. In addition, it can also ensure that the rivet block 21 and the elastic rubber pad are always in contact, so that they can be shaped. Further, the reset spring 215 includes multiple reset springs 215, and the multiple reset springs 215 are evenly or symmetrically arranged on the rivet block 21 to ensure force balance. Among them, the rivet blocks above and below the elastic rubber pad are positioning plates 213 and pressing plates 212 respectively, and the connecting piece 216 is a connecting bolt, and the two ends of the reset spring 215 are respectively hung on the connecting bolts on the positioning plate 213 and the pressing plate 212.

[0031] As another specific embodiment, the lower die base 1 is provided with a positioning groove 11 which is open upwards, and the positioning groove 11 is also through-through in the front and rear directions. Since the length of the plug assembly 3 is longer than the length of the lower die base 1, the position of the press riveting is the middle of the plug assembly 3, and the front and rear ends of the plug assembly 3 can pass through the positioning groove 11 which is through-through in the front and rear directions. Specifically, the shape and size of the positioning groove 11 match the plug assembly 3.

[0032] As another specific embodiment, the left and right sides of the positioning groove 11 are also connected with a through rivet groove. The rivet can be positioned by the width of the groove, and the through groove can facilitate the processing of the positioning groove.

[0033] As another specific embodiment, the lower die base 1 is further provided with a positioning block 12, and the positioning block 12 is arranged in front of or behind the positioning groove 11. Since the positioning groove 11 can only position the plug assembly 3 therein, the positioning block 12 can position the exposed portion arranged in front of or behind the lower die base 1. Further, the positioning block 12 is fixedly arranged on the lower die base 1.

[0034] As another specific embodiment, the positioning block 12 is provided with a positioning plug plate 13 extending upward, and the two planes of the positioning plug plate 13 are parallel in the front-to-back direction. Since the insert 32 is fork-shaped, there is a gap between the two forks, and the positioning plug plate 13 can be fixed in the gap, thereby positioning the insert 32.
