The third electric push rod 21 and the second pressure sensor 22, the two sets of L-shaped frames 14 are respectively located on both sides of the upper outer surface of the worktable 1, the second electric push rod 15 is located on the upper outer surface of the L-shaped frame 14, the first pressure sensor 16 is located on the lower outer surface of the second electric push rod 15, the fixing plate 6 is located on the lower outer surface of the first pressure sensor 16, the limiting groove 7 is opened on one side of the outer surface of the fixing plate 6, the two sets of fixing rods 10 are respectively located at the front and rear ends of the moving inner surface of the fixing plate 6, and the mounting plate 8 is located on one side of the upper outer surface of the fixing plate 6.

[0019] The first electric push rod 9 is located in the middle of the mounting plate 8. The insert plate 12 is located on the lower outer surface of the first electric push rod 9. The slot 13 is opened on one side of the upper outer surface of the clamping plate 4. Two sets of guide grooves 11 are respectively opened at the front and rear ends of one side of the outer surface of the clamping plate 4. The buffer plate 17 is located on one side of the outer surface of the L-shaped frame 14. The fixing frame 18 is located on one side of the outer surface of the worktable 1. The slot 20 is opened at the upper end of one side of the outer surface of the fixing frame 18. The third electric push rod 21 is located at the lower part of the slot 20. The second pressure sensor 22 is located at the lower part of the third electric push rod 21. On one side of the outer surface of the push rod 21, the second guide rod 19 is located at the upper end of one side of the outer surface of the L-shaped frame 14, and the second pressure sensor 22 is located between the third electric push rod 21 and the L-shaped frame 14; the clamping plate 4 and the limiting groove 7 are slidably connected, the clamping plate 4 is slidably connected to the fixing rod 10 through the guide groove 11, and the insert plate 12 and the slot 13 are plugged in; the first pressure sensor 16, the second pressure sensor 22, the second electric push rod 15, the third electric push rod 21, the first electric push rod 9 and the control panel 3 are all electrically connected.

[0020] It should be noted that this utility model is a positioning fixture for machining thin-walled parts of aircraft. By placing the workpiece 2 on the worktable 1, with one end of the workpiece 2 abutting against the buffer plate 17 on one side of the L-shaped frame 14, and simultaneously activating the second electric push rod 15 to lower the first pressure sensor 16, the clamping plate 4 is moved to one side of the upper end of the workpiece 2. The first pressure sensor 16 transmits data to the control panel 3, which in turn controls the second electric push rod 15 to activate another set of third electric push rods 21. This moves the L-shaped frame 14 to one side while simultaneously causing the second guide rod 19 to slide along the slot 20. The second pressure sensor... Sensor 22 transmits data to control panel 3, which controls the third electric push rod 21 to move the other end of workpiece 2 to one side of buffer plate 17 for positioning and clamping of workpiece 2. This facilitates positioning and clamping of workpiece 2 and allows for adjustment of the clamping plate 4 position according to the length of workpiece 2. Controlled by control panel 3, the first electric push rod 9 drives the insert plate 12 to slide upward along slot 13, pulling the clamping plate 4 and causing the guide groove 11 to slide along the fixing rod 10. The clamping plate 4 is then slid out along the limiting groove 7 for replacement. This allows for easy installation, removal, and replacement of the clamping plate 4, and the operation is simple.
