[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0019] This application discloses an adjustable sheet metal processing fixture. (Refer to...) Figure 1-4An adjustable sheet metal processing fixture includes a support frame 4, support plates 8, and limiting rods 10. A positioning block 12 is fixedly connected to one side of the top of the support frame 4. Support plates 8 are installed on the top of the positioning block 12 and the other side of the top of the support frame 4. A guide block 1 is fixedly connected to the bottom of one of the support plates 8, and the guide block 1 engages with the positioning block 12. A plug rod 7 is fixedly connected to one side of one of the support plates 8. Threaded rods 6 are movably installed on both sides of the two support plates 8. A limiting rod 10 is movably installed on the top of the support plate 8, and the limiting rod 10 is threadedly connected to the threaded rod 6. A shaft block 11 is movably installed inside the limiting rod 10. The shaft block 11 has a limiting hole 1101 inside. A positioning bolt 3 is movably installed at one end of the limiting rod 10, and the positioning bolt 3 engages with the limiting hole 1101. Positioning plates 2 are fixedly connected to both sides of the shaft block 11. The operator places a small sheet metal workpiece between the two limiting rods 10. Tightening the threaded rod 6 causes the limiting rod 10 to move towards the sheet metal workpiece via the threaded rod 6, clamping and limiting the sheet metal workpiece through the limiting rod 10. When it is necessary to clamp and fix a larger sheet metal workpiece, the operator can also pull up the positioning plate 2, causing the shaft block 11 to rotate 90°, and then screw the positioning bolt 3 into the limiting hole 1101 to limit the angle between the shaft block 11 and the positioning plate 2. Tightening the threaded rod 6 allows the positioning plate 2 and the limiting rod 10 to cooperate in clamping and limiting the larger sheet metal workpiece. This allows the operator to freely adjust the clamping method of the device according to the type of sheet metal workpiece, meeting more clamping and processing needs. The operator can also pull the support plate 8 to adjust the extension length of the insert rod 7, causing the guide block 1 to slide inside the positioning block 12, thereby adjusting the distance between the two support plates 8. This makes it easier for the operator to perform up and down bending processing on the sheet metal workpiece, and makes it easier for the operator to adjust the device and process the sheet metal workpiece.

[0020] Reference Figure 1 Both ends of the support plate 8 are provided with limiting grooves 9, and the limiting rod 10 is fitted with the limiting grooves 9. The limiting grooves 9 can guide and limit the movement direction of the limiting rod 10, thereby improving the stability of the movement of the limiting rod 10.

[0021] Reference Figure 4 Another support plate 8 has a guide groove 801 at its bottom, and the insertion rod 7 is fitted into the guide groove 801. The insertion rod 7 can move inside the guide groove 801 and be inserted into the guide groove 801 to shorten the distance between the two support plates 8.

[0022] Reference Figure 1 A fixing bolt 13 is movably installed between the support plate 8 and the insertion rod 7. The fixing bolt 13 is made of stainless steel. Screwing the fixing bolt 13 between the support plate 8 and the insertion rod 7 increases the friction between the support plate 8 and the insertion rod 7, thereby fixing the support plate 8 and the insertion rod 7.

[0023] Reference Figure 1 A connecting block 501 is fixedly connected to one side of the bottom of the support plate 8, and a handle 5 is fixedly connected to the inner side of the connecting block 501. The operator holds the handle 5 and pulls to adjust the distance between the support plates 8. The connecting block 501 connects and fixes the handle 5 to the support plate 8.

[0024] The implementation principle of an adjustable sheet metal processing fixture according to an embodiment of this application is as follows: First, a smaller sheet metal workpiece is placed between two limiting rods 10. The threaded rod 6 is turned so that the limiting rod 10 moves toward the sheet metal workpiece through the threaded rod 6, thereby clamping and limiting the sheet metal workpiece. If a larger sheet metal workpiece needs to be clamped, the operator pulls and lifts the positioning plate 2, causing the shaft block 11 to rotate 90°. Then, the positioning bolt 3 is screwed into the limiting hole 1101 to limit the angle between the shaft block 11 and the positioning plate 2. Next, the threaded rod 6 is turned so that the positioning plate 2 and the limiting rod 10 cooperate to clamp and limit the larger sheet metal workpiece. The operator can also adjust the extension length of the insert rod 7 by pulling the support plate 8, so that the guide block 1 slides inside the positioning block 12, thereby adjusting the distance between the two support plates 8, which facilitates the up and down bending processing of the sheet metal workpiece.
