[0054] Specifically, please refer to Figures 2-5 , the mounting assembly 11 comprises a mounting block 112 and a mounting plate 111, the mounting block 112 is arranged on the side of the mounting plate 111 facing the fixed seat 2, and the mounting block 112 is used for connecting the pressing assembly 12, wherein in the embodiment, the number of the pressing assembly 12 is matched with the number of the push assembly 21, that is, one pressing assembly 12 matches one push assembly 21, that is, one pressing assembly 12 matches two push blocks.

[0055] In the embodiment, the pressing assembly 12 comprises a pressing block, and a second inclined surface 121 is arranged on the side of the pressing block facing the push block, wherein in the pressing state of the pressing assembly 12, the first inclined surface 2111 and the second inclined surface 121 are in close contact and slide against each other, specifically, the driving member drives the pressing piece 1 to move up and down on the guide column 3, the mounting assembly 11 is pressed downward to make the pressing block press downward, the first inclined surface 2111 and the second inclined surface 121 are in close contact, at this time the pressing piece 1 continues to slide downward, causing the pressing block to continue to press downward, and then the sliding block 211 in the push block bears the pressure from the pressing block, and the sliding block slides to the side of the side-out iron shell side wall, and then the iron shell to be processed is riveted.

[0056] In order to ensure that the pressing block does not continue to slide downward, in the embodiment, the fixed seat 2 is provided with a limiting groove 23, the limiting groove 23 abuts against the end of the pressing assembly 12 after being pressed downward, and the limiting groove 23 is used for limiting the pressing range of the pressing assembly 12.

[0057] It should be noted that in the embodiment, the limiting groove 23 is matched with the number of push blocks, and a blocking block is arranged between the limiting grooves 23, so that the pressing block has a gap on one end of the second inclined surface 121, and the gap is used for accommodating the blocking block, so as to ensure that the end of the pressing block can abut against the bottom of the limiting groove 23, and the above-mentioned arrangement ensures that each push block is balanced. In other embodiments, the blocking block can not be arranged, and the pressing block directly applies pressure to the two push blocks to make them slide normally.

[0058] As for the rivet head assembly 13 arranged on the mounting assembly 11, please refer toFigure 1 and Figure 2 In the embodiment, the rivet head assembly 13 includes an upper rivet head, which is arrow-shaped at one end facing the riveted end of the iron shell to be processed, facilitating the pressing of the riveted end of the iron shell to be processed to form the required iron shell.

[0059] Regarding the operation of the rivet head assembly 13, in the embodiment, the rivet head assembly 13 also presses the riveted end of the iron shell to be processed as the pressing piece 1 moves downward. It should be noted that the length of the upper rivet head is less than the length of the pressing block. When the iron shell to be processed is riveted, the arrow-shaped end of the upper rivet head also continuously presses the riveted end of the iron shell until the bottom of the pressing block abuts against the bottom of the limiting groove 23.

[0060] Further, the iron shell riveting jig also includes a pre-pressing assembly 14, which mainly stabilizes the position of the iron shell to be processed in the fixed seat 2 during the riveting process, avoiding the displacement of the iron shell to be processed during the riveting process, which affects the riveting effect of the iron shell.

[0061] In the embodiment, the bottom of the mounting assembly 11 is provided with a sliding groove in the internal direction thereof, and one end of the pre-pressing assembly 14 is slidably connected with the sliding groove, and the other end faces the riveted end of the iron shell to be processed. When the end of the pre-pressing assembly 14 facing the riveted end of the iron shell to be processed is stressed, the other end of the pre-pressing assembly 14 slides in the sliding groove and abuts against the inside of the mounting assembly 11.

[0062] Specifically, referring to Figure 2 and Figure 5 The pre-pressing assembly 14 includes a pre-pressing shaft 141, and one end of the pre-pressing shaft 141 located inside the sliding groove is provided with a limiting circular block 142. The inner diameter of the part of the sliding groove communicating with the outside is less than the diameter of the limiting circular block 142, which ensures that the pre-pressing shaft 141 cannot fall out of the sliding groove, and the limiting circular block 142 can abut against the top inside of the sliding groove.

[0063] Regarding the overall operation of the iron shell riveting jig, first, the iron shell to be processed is installed at the corresponding position of the fixed seat 2, with the side wall of the side turned outward of the iron shell to be processed facing the direction of the pressing piece 1. Then, the driving piece receives the corresponding instruction to drive the pressing piece 1 to move up and down on the guide column 3, so that the pressing assembly 12 presses the pushing assembly 21, the pushing assembly 21 is stressed smoothly, and then the side wall of the side turned outward of the iron shell to be processed is riveted. In this process, the end of the pre-pressing assembly 14 slides in the sliding groove until it abuts against the top inside of the sliding groove, ensuring that the iron shell to be processed does not displace, and also cooperating with the limiting groove 23 to ensure the downward movement range of the pressing piece 1. Secondly, in the above process, after the side wall of the side turned outward of the iron shell to be processed is riveted, the rivet head assembly 13 further presses the corresponding riveted end twice to form the required iron shell. After the above operation is completed, the driving piece drives the pressing piece 1 to move up on the guide column 3, and then the formed iron shell is taken out, thus completing the entire operation.

[0064] The above merely describes optional embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields under the inventive concept of the present application, or the contents of the present application specification and drawings are included in the patent protection scope of the present application.
