DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in the present embodiment, a fixture for processing thin-walled metal parts comprises a base plate 1, a displacement groove 2 is formed through the surface of the base plate 1, a displacement block 3 is slidably connected inside the displacement groove 2, a displacement plate 4 is fixedly connected to one side of the displacement block 3, two second vertical plates 15 are fixedly connected to one side of the displacement plate 4, a buffer assembly is arranged between the two second vertical plates 15, and two first vertical plates 5 are fixedly connected to the bottom of the base plate 1, a clamping assembly is arranged between the two first vertical plates 5, and the clamping assembly is used to drive the buffer assembly to move.

[0022] First, by placing the metal part on the top of the base plate 1, and then starting the clamping assembly to drive the buffer assembly to automatically clamp the metal part, the thin-walled metal part can be automatically clamped, reducing manual operation time, improving production efficiency, and increasing the practicality of the device. Then, the buffer assembly contacts the metal part, thereby reducing the direct contact of the clamp with the thin-walled metal part, reducing scratches and damage, and extending the service life of the thin-walled metal part, thereby further increasing the practicality of the device.

[0023] like Figure 1-Figure 4 As shown, the clamping assembly includes a sliding rod 9, which is fixedly connected between the two first vertical plates 5. Two movable blocks 8 are movably sleeved on the outer side of the sliding rod 9. The tops of the two movable blocks 8 are fixedly connected to the bottom of the displacement block 3. The clamping assembly also includes two fixed plates 6, which are respectively fixedly connected to the bottoms of the two movable blocks 8. A cylinder 18 is fixedly installed on one side of one of the fixed plates 6, and one end of the movable rod of the cylinder 18 is fixedly connected to one side of the other fixed plate 6. A through groove 19 is opened inside the movable block 8, and a rotating rod 7 is rotatably connected to the bottom of the bottom plate 1, and a second connecting rod 17 is rotatably connected between one side of the rotating rod 7 and the inside of the through groove 19.

[0024] When clamping, the cylinder 18 is started to move the movable rod, driving the two fixed plates 6 to approach each other and at the same time driving the rotating rod 7 to rotate and drive the two first connecting rods 12 to rotate. Then the two first connecting rods 12 rotate to drive the two movable blocks 8 to slide on the outside of the sliding rod 9. The sliding rod 9 increases the stability of the movement of the movable block 8. Then the movable block 8 moves to drive the displacement block 3 to slide inside the displacement groove 2, thereby further increasing the stability of clamping.

[0025] like Figure 1-Figure 4As shown, the buffer assembly includes a fixed rod 10, which is fixedly connected between two second vertical plates 15. Two sliders 16 are movably sleeved on the outer side of the fixed rod 10. The buffer assembly also includes a spring 13, which is fixedly connected between the two sliders 16. A clamping plate 11 is provided on one side of the two sliders 16. A first connecting rod 12 is rotatably connected between one side of the clamping plate 11 and the two sliders 16. An anti-slip pad 14 is provided on one side of the clamping plate 11.

[0026] When the clamping plate 11 contacts the metal part, the clamping plate 11 is moved and the two second connecting rods 17 are rotated, and then the two sliders 16 are moved closer to each other on the outside of the fixing rod 10 and the spring 13 is compressed. Under the reaction of the spring 13, the hard contact between the clamping plate 11 and the metal part is reduced, thereby protecting the metal part from damage.

[0027] The utility model provides a clamp for processing thin-walled metal parts, and the specific working principle is as follows: first, the metal part is placed on the top of the bottom plate 1, and then the movable rod is moved by starting the cylinder 18 to drive the two fixed plates 6 to approach each other and drive the rotating rod 7 to rotate and drive the two first connecting rods 12 to rotate, and then the two first connecting rods 12 rotate to drive the two movable blocks 8 to slide on the outside of the slide rod 9, and the stability of the movement of the movable block 8 is increased by the slide rod 9, and then the movable block 8 moves to drive the displacement block 3 to slide inside the displacement groove 2, and then the displacement block 3 moves to drive the displacement plate 4 to move and drive the clamping plate 11 to move, and then when the clamping plate 11 conflicts with the metal part, the clamping plate 11 is driven to move and drive the two second connecting rods 17 to rotate, and then the two sliding blocks 16 are driven to approach each other on the outside of the fixed rod 10 and compress the spring 13, and under the reaction of the spring 13, the hard contact between the clamping plate 11 and the metal part is reduced, thereby protecting the metal part from damage.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
