[0055] A plurality of profiling grooves 31 are formed on the top of the fixing plate 29 , and a limiting seat 32 is formed on the side of each profiling groove 31 .

[0056] The utility model provides a hot riveting device. When hot riveting a bracket 3 and a shell 4, first, the riveting column of the shell 4 is passed through the pre-opened hole of the bracket 3, and then the combination of the two is fixed to the feeding plate 2 through a fixing mechanism; then the first driving mechanism drives the hot pressing head 5 to move, and the hot pressing head 5 presses the hot riveting column that has passed through the bracket 3, and then the hot pressing head 5 is powered on to generate heat (it can also be powered on to generate heat before contacting the hot riveting column), and the heat of the hot pressing head 5 melts the top of the hot riveting column; after the top of the hot riveting column is formed, the cooling mechanism cools the bottom of the hot pressing head 5, and finally the first driving mechanism separates the hot pressing head 5 from the hot riveting head, and the riveting of the bracket 3 and the shell 4 is completed; wherein in the above riveting process, the power supply and displacement of the hot pressing head 5 are all automatically controlled by a computer, so that the efficiency is higher and the hot riveting effect is also better.

[0057] During actual operation, first, the motor drives the first driving screw 9 to rotate, and moves the first linkage block 7, the feeding plate 2, the fixing plate 29, etc. to the edge of the supporting base plate 1, so that the worker can load the material; after the feeding plate 2 reaches the appropriate position, the worker inserts the combination of the bracket 3+shell 4 into the profiling groove 31, and makes the top of the riveted column face upward; then the limiting seat 32 is rotated to make the lower side of the anti-slip arm 33 contact the top of the bracket 3 or the shell 4, at this time, the bottom and periphery of the bracket 3+shell 4 are limited by the inner wall of the profiling groove 31, and the top is limited by the anti-slip arm 33, so the position stability of the bracket 3+shell 4 can be guaranteed; The shape of the profiling groove 31 matches the shape of the lower side of the bracket 3+shell 4. At the same time, there can be multiple profiling grooves 31 on the same profiling portion 30. The profiling grooves 31 can be several identical ones, so that multiple brackets 3+shells 4 of the same model can be hot-riveted at one time; they can also be profiling grooves 31 of different models, so that they can be suitable for combinations of brackets 3+shells 4 of different models, reducing costs; or in actual use, the fixing plate 29 and the feeding plate 2 are detachably connected by threads, so that different fixing plates 29 and profiling portions 30 can be selected according to different combinations of brackets 3+shells 4.

[0058] After that, the motor drives the first driving screw 9 to rotate, and the feeding plate 2 and the bracket 3 + shell 4 are sent to the specified position; then the motor connected to the second driving screw 14 drives the second driving screw 14 to rotate, and horizontally moves the second linkage block 13, so that the support frame 15 moves horizontally until the heating head is located directly above the hot riveting column that needs hot riveting at this time; the lifting cylinder 19 drives the lifting frame 17 to descend, and makes the hot pressing head 5 contact the top of the hot riveting column; then the lifting rod continues to drive the lifting frame 17 downward, at this time, the buffer column 22 and the buffer frame 21 have relative movement, and the elastic member 24 is elastically deformed, so that the buffer frame 21 can slowly and gradually apply pressure through the elastic member 24, and the hot pressing head 5 gradually generates corresponding pressure with the hot riveting column, which can better prevent the hot pressing head 5 from being damaged, and also can better prevent the hot riveting column from being broken;

[0059] After the hot riveting is completed, a compressed air pipe is connected to the top of the buffer column 22, and the compressed air pipe introduces compressed air into the cooling channel 27. After the compressed air is ejected through the cooling pipe 28, it directly acts on the bottom of the hot pressing head 5, and quickly reduces the temperature of the hot riveting column. Finally, the hot pressing head 5 is raised and separated from the hot riveting column. After that, the first drive screw 9 and the second drive screw 14 cooperate to move the hot pressing head 5 to the top of the next hot riveting column for the next round of hot riveting, which is simple and fast. The first drive screw 9 is perpendicular to the angle of the second drive screw 14, and the second drive screw 14 is higher than the first drive screw 9. In this way, the cooperation of the two can perform hot riveting on all hot riveting columns that can be acted on, which can improve the extensiveness of hot riveting.

[0060] When the hot pressing head 5 is actually performing hot riveting, the hot pressing head 5 has a lower temperature at first and will act on the top of the hot riveting column first. Then, after heating for a short period of time, the temperature rises and the hot riveting column is further heated, so that the top of the hot riveting column can be better heated and deformed. Finally, the hot pressing head 5 is kept in a power-off position and ventilated for cooling. When the top of the hot riveting column is shaped, the hot pressing head 5 rises, so that the shape of the top of the hot riveting column is better, thereby improving product quality.

[0061] When the lifting frame 17 is descending, its inner side is movably engaged with the lifting rail 16 through the lifting block 18, so the lifting frame 17 can be stably lifted and lowered vertically; secondly, when the buffer column 22 is lifted and lowered, the stabilizing block 23 on its outer wall is engaged with the stabilizing bar 25 through the stabilizing groove, so that the angle of the buffer column 22 is also stable, so that the angle of the hot pressing head 5 can be better guaranteed, and the hot pressing quality can be guaranteed.

[0062] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
