After continuous research and design and repeated sample test and improvement, the utility model with practical value is finally created.

Referring to fig. 2-3, an embodiment of the present utility model provides a bending auxiliary fixing jig, which includes a mounting base 1, an up-down moving mechanism 2, an adjustable clamping fixing mechanism 3 and an adjustable limiting mechanism 4; wherein,

the up-and-down moving mechanism 2 and the adjustable limiting mechanism 4 are respectively arranged on the mounting base 1, and the adjustable clamping and fixing mechanism 3 is arranged on the up-and-down moving mechanism 2;

the up-and-down moving mechanism 2 is used for driving the adjustable clamping and fixing mechanism 3 to move up and down relative to the mounting base 1;

the adjustable clamping and fixing mechanism 3 is used for clamping and fixing a workpiece to be bent;

the adjustable limiting mechanism 4 is used for abutting against the workpiece to be bent so as to limit the movement of the workpiece to be bent in the horizontal direction.

It should be noted that, in this embodiment, a general auxiliary fixing jig for bending is added on the basis of the original bending machine, so that after the auxiliary fixing jig for bending is fixed on the bending machine, the auxiliary fixing jig for bending can perform auxiliary fixing on the workpiece to be bent, specifically, the workpiece to be bent is clamped and fixed by the adjustable clamping and fixing mechanism 3, and the workpiece to be bent is limited in the horizontal direction by the adjustable limiting mechanism 4.

It can be understood that the up-and-down movement adjusting capability of the up-and-down movement mechanism 2 enables the height of the adjustable clamping and fixing mechanism 3 to be raised or lowered so as to adapt to workpieces to be bent of different types or sizes, in addition, the clamping gap of the adjustable clamping and fixing mechanism 3 is also adjustable so as to further adapt to the workpieces to be bent of different types or sizes, so that the universality is strong and the utilization rate is high.

The jig is connected with the bending machine through bolts through the mounting base 1, and is simple and convenient to mount.

Referring to fig. 4, in the present embodiment, the mounting base 1 includes a base body 11, a first clamping groove 12 and a second clamping groove 13 are formed on the base body 11, and a mounting plane 14 is provided on the mounting base 1;

When the clamping arm 22 is clamped in the first clamping groove 12, a fastening bolt is generally used to fix the clamping arm and the first clamping groove.

As shown in fig. 5, the head of the adjusting bolt 23 abuts against the mounting base 1, and when the adjusting bolt 23 is screwed in, the length of the head of the adjusting bolt 23 extending out of the clamp arm 22 becomes shorter, so that the relative distance between the first fixing block 21 and the clamp arm 22 and the mounting base 1 becomes smaller, and the height of the adjustable clamping and fixing mechanism 3 is reduced; when the adjusting bolt 23 is screwed out, the length of the head of the adjusting bolt 23 extending out of the clamp arm 22 becomes longer, so that the relative distance between the first fixing block 21 and the clamp arm 22 and the mounting base 1 becomes larger, and the height of the adjustable clamp fixing mechanism 3 increases.
