The end of the working block 401 is provided with a plurality of jacks 4011 suitable for inserting the first terminals 703 of the parts, the jacks 4011 correspond to the limiting grooves 2012 one by one, and the limiting grooves 2012 correspond to the first terminals 703 one by one, so the jacks 4011 correspond to the first terminals 703 one by one. The fourth driving mechanism is a third air cylinder 406, a cylinder body of the third air cylinder 406 is fixedly connected with the first fixing plate 402 through a third connecting block 407, and an expansion link of the third air cylinder 406 is fixedly connected with the first moving plate 404.

The bending mechanism further comprises a limiting block 601, a groove 6011 suitable for placing the shell 701 of the part is recessed in the top surface of the limiting block 601, and the limiting block 601 is located between the first top block 101 and the second top block 201. The shape of the recess 6011 here matches the shape of the housing 701, so that the housing 701 cannot move in the horizontal direction when the housing 701 is placed in the recess 6011.

In an initial state, the working block 401 of the bending jig is located on one side of the first protruding portion 2011, which is far away from the part, the working block 401 abuts against the first protruding portion 2011, and the length direction of the jack 4011 is consistent with the length direction of the corresponding limiting groove 2012.

The working process of the bending jig is as follows: the end of the plug 702, in which the first terminal 703 and the second terminal 704 are inserted, is manually inserted into the cylindrical portion 7013 (without pressing the plug 702 to the bottom in the cylindrical portion 7013), and the first terminal 703 and the second terminal 704 are caused to pass through their corresponding through holes. The parts are then placed on the stop 601 so that the housing 701 is placed in the recess 6011 with the barrel 7013 and the plug 702 pointing towards the first top piece 101 and the end of the first terminal 703 and the notch 7014 aligned with the second top piece 201.

Then, the second cylinder 3 is activated, so that the terminal bending mechanism 2 moves integrally in the direction of the component, and the end of the second ejector block 201 extends into the housing 701 from the notch 7014 and abuts against the inner side of the side wall 7012. At this time, the first terminal 703 is inserted into the corresponding jack 4011, and a part of the first terminal 703 is located in the corresponding limiting groove 2012, the limiting groove 2012 has an effect of positioning the first terminal 703, and the second terminal 704 is located in the corresponding avoiding groove 202, and since this process does not process the second terminal 704, the avoiding groove 202 is provided to avoid the second terminal 704 from being damaged due to the second ejector block 201 touching the second terminal 704.

Then, the fourth cylinder 102 is activated again, so that the first ejecting block 101 moves toward the component, and after the first ejecting block 101 abuts against the plug 702, the plug 702 is pressed into the cylindrical portion 7013 until the end of the plug 702 abuts against the side wall 7012.

Then, the rotary cylinder 5 is started to rotate the rotary shaft to drive the inserting mechanism to rotate around the first axis, so that the first terminal 703 is bent under the driving of the working block 401.

Then, the third air cylinder 406 is activated again, so that the working block 401 moves in a direction away from the first protruding portion 2011 until the first terminal 703 is no longer inserted into the inserting hole 4011, and at this time, the machined part is removed.

According to another embodiment, the device further comprises a third slide rail 603, a third slider 602 is fixed at the bottom of the limiting block 601, and the third slider 602 is in sliding fit with the third slide rail 603. The length direction of the third slide rail 603 is perpendicular to the first line.

The end of the telescopic rod of the fifth cylinder 604 is fixedly connected with the limiting block 601 through a fourth connecting block 6041, and the telescopic direction of the telescopic rod of the fifth cylinder 604 is perpendicular to the first straight line.

In this embodiment, the fifth cylinder 604 can drive the first limiting block 601 to move, when a part needs to be manually placed on the limiting block 601, the fifth cylinder 604 is started, so that the limiting block 601 moves to a feeding station, the part is manually placed on the limiting block 601 at the moment, then the fifth cylinder 604 is started, so that the limiting block 601 moves to an operation station (namely, the position where the limiting block 601 is located in the first embodiment), and then the starting device is used for assembling and bending the part.

The feeding station is far away from the first ejector block and the second ejector block relative to the operation station, so that the danger caused by too short distance between the feeding station and the first ejector block 101 and the second ejector block 201 in manual discharging is avoided.
