[0033] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 10In an embodiment of the utility model, a terminal riveting jig includes a frame 1, a fixed seat 2 for placing a workpiece to be riveted is provided on the frame 1, a riveting mechanism 3 for pressing the terminal into the workpiece is provided on the frame 1, an insert 4 embedded in the workpiece for supporting the riveting position is provided in the fixed seat 2, and a driving component 5 is provided in the fixed seat 2 for driving the insert 4 into the product for support and separating the workpiece after riveting from the insert 4. When the terminal is riveted, the riveting position is suddenly subjected to force, which is prone to deformation and breakage. In the present application, by providing the insert 4 to support the workpiece, it is possible to prevent force distribution when riveting the terminal, prevent the product from breaking, deforming and other problems, and improve the yield rate.

[0035] It should also be noted that an avoidance groove 40 may be provided in the insert 4 , and the terminal after riveting may be inserted into the avoidance groove 40 after passing through the workpiece.

[0036] Furthermore, the fixing seat 2 includes a base 20 arranged on the frame 1 and a limiting seat 21 arranged on the base 20. The base 20 is formed with a groove 22 for placing a workpiece, and the limiting seat 21 is formed with a sliding groove 23 for placing an insert 4. The driving component 5 drives the insert 4 to extend from the rear end of the sliding groove 23 into the groove 22 and drives the extended insert 4 into the sliding groove 23. When riveting, the workpiece is placed in the groove 22, and the limiting seat 21 can support the rear end of the workpiece.

[0037] Further, the driving assembly 5 includes a sliding rod 50 that is slidably matched with the base 20, and a driving cylinder 51 that is arranged on the frame 1 and is used to drive the sliding rod 50 to reciprocate on the base 20. A limiting hole 52 is formed on the sliding rod 50, and a top block 53 that is slidably matched with the sliding rod 50 is provided on the limiting seat 21. The lower part of the top block 53 passes through the limiting hole 52 and then slides with the frame 1. The upper part of the top block 53 can pass through the limiting seat 21. A pulling hole 54 that passes through the limiting hole 52 is transversely provided on the sliding rod 50. The pulling hole 54 is inclinedly arranged, and a limiting shaft 55 that is slidably matched with the pulling hole 54 is provided on the top block 53. A first inclined surface 56 is formed at the front end of the insert 4, and a second inclined surface 57 that is matched with the first inclined surface 56 is formed on the upper part of the top block 53.

[0038] Connecting blocks 41 are formed at the left and right ends of the insert 4, and a limiting portion 42 corresponding to the connecting block 41 is formed in the sliding groove 23. A spring 43 for pushing the insert 4 back into the limiting seat 21 is provided between the limiting portion 42 and the connecting block 41; in the initial state, the top block 53 is located at the bottom, and the insert 4 is pushed into the sliding groove 23 under the action of the spring 43. After the workpiece is placed, the driving cylinder 51 drives the sliding rod 50 to move forward. The top block 53 will be lifted upward under the action of the pulling hole 54, and the second inclined surface 57 on the top block 53 will squeeze the first inclined surface 56 of the insert 4. The insert 4 is moved to the workpiece for support under the action of the top block 53. Anyway, after the driving cylinder 51 is reset, the insert 4 is also reset under the action of the spring 43, and the workpiece can be taken out.

[0039] Furthermore, spring holes 44 are provided on the limiting portion 42 and the connecting block 41, and both ends of the spring 43 are inserted into the corresponding spring holes 44;

[0040] In addition, as another preferred solution of this embodiment, a connecting shaft can be provided on the limiting portion 42, and the spring 43 can be sleeved on the connecting shaft;

[0041] In the first solution, after the inventor tested, it was found that the spring 43 would not deviate because there was not much room for movement around it, and a spring hole 44 was set, with both ends of the spring 43 embedded in the spring hole 44, which could make it more stable during operation and without abnormalities in use. Therefore, the first solution can save a connecting shaft and save costs.

[0042] Furthermore, the riveting mechanism 3 includes a riveting cylinder 30 arranged on the driving cylinder 51, a pair of spaced support columns 31 are provided on the frame 1, a sliding member 32 slidably matched with the support columns 31 is provided between the support columns 31, the rear end of the sliding member 32 is connected to the piston rod of the riveting cylinder 30, and a riveting member 33 for pressing the terminal into the workpiece is provided on the sliding member 32;

[0043] Since the driving cylinder 51 is arranged on the riveting cylinder 30, the entire riveting mechanism 3 and the driving assembly 5 are stacked together, which can save space. It should also be noted that the sliding rod 50 in the driving assembly 5 passes through the bottom of the sliding member 32 and reaches the base 20.

[0044] Furthermore, a baffle 34 is provided at the front end of the support column 31, and an adjusting bolt 35 for limiting the sliding member 32 is provided on the baffle 34. By setting the adjusting bolt 35, the sliding member 32 can be limited, so as to facilitate the adjustment of the forward movement depth of the sliding member 32, thereby facilitating the adjustment of the riveting depth of the terminal.

[0045] Furthermore, the baffle plate 34 is also provided with a stripping mechanism 6 for removing the terminal material strip. The stripping mechanism 6 includes a stripping cylinder 60 arranged on the top of the baffle plate 34, and a slider 61 is provided on the baffle plate 34 to slide with it. The upper part of the slider 61 is connected to the piston rod of the stripping cylinder 60, and the bottom of the slider 61 is provided with a pressing piece 62 for pressing out the terminal material strip. After the terminal riveting is completed, the excess connecting material strip needs to be removed. In the present application, the stripping cylinder 60 drives the pressing piece 62 to press against the terminal material strip, so that the excess material strip can be separated from the terminal.

[0046] Furthermore, a discharge chute 63 is provided at the rear end of the base 20, and a drawer 64 is provided at the bottom of the frame 1. The drawer 64 is located at the bottom of the discharge chute 63 and is used to receive terminal strips. By setting up the drawer 64, the terminal strips can be collected for easy cleaning.

[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
