The terms "install", "connect", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0027] The present application is further described in detail below through drawings and examples.

[0028] Reference Figures 1 to 4The embodiment of the present application provides a fixture for processing the slender shaft of a refrigerator component, comprising a first base 1, a clamping assembly 2 is provided on the inner wall of the first base 1, and a rotating assembly 3 is provided at one end of the clamping assembly 2; the clamping assembly 2 comprises a first mounting plate 21, the first mounting plate 21 is fixedly connected to the inner wall of the first base 1, an assembly ring 22 is rotatably connected to one side of the first mounting plate 21, a protruding block 23 is fixedly connected to the outer wall of the assembly ring 22, a first nut block 24 is rotatably connected to one side of the protruding block 23, a mounting block 25 is rotatably connected to one side of the first mounting plate 21, a screw rod 26 is rotatably connected to the inside of the mounting block 25, the screw rod 26 is threadedly connected to the inside of the first nut block 24, a positioning block 28 is rotatably connected between the inner wall of the assembly ring 22, a sliding rod 29 is rotatably connected to one side of the first mounting plate 21, the sliding rod 29 is slidably connected to the inside of the positioning block 28, and a roller 210 is fixedly installed at one end of the sliding rod 29. An anti-slip rotating ring 27 is fixedly connected to one end of the screw rod 26. A docking rod 211 is fixedly connected to one side of the first mounting plate 21 .

[0029] During specific implementation: by twisting the anti-slip rotating ring 27 to rotate, the screw rod 26 is driven to rotate, and the rotation of the screw rod 26 will prompt the first nut block 24 to move forward along the screw rod 26. Since the protruding block 23 is fixedly connected to the assembly ring 22, and the assembly ring 22 can also rotate, when the first nut block 24 moves, it will drive the assembly ring 22 to rotate through the protruding block 23, and the first nut block 24 and the mounting block 25 are both rotatable and can adapt to the position angle change caused by the rotation of the assembly ring 22. The rotation of the assembly ring 22 will prompt the positioning block 28 to perform a circular motion as a whole. With the displacement of the positioning block 28, the sliding rod 29 will slide inside it, and slowly the three rollers 210 will continue to move closer to the middle center of the circle to clamp and fix the slender shaft. And because the roller 210 can roll, when the slender shaft is clamped, the slender shaft can also rotate, which is also convenient for adapting to slender shafts of different diameters, and is also convenient for spraying coolant to cool down during processing.

[0030] Reference Figures 1 to 4 In one aspect of the present embodiment, the rotating assembly 3 includes a second base 31, the inner wall of the second base 31 is fixedly connected to a second mounting plate 32, and one side of the second mounting plate 32 is fixedly connected to one end of the docking rod 211. A rotating disk 33 is rotatably connected inside the second mounting plate 32, and a docking seat 34 is fixedly installed on one side of the rotating disk 33, and a plug hole 37 is provided inside the docking seat 34. A hydraulic rod 35 is also fixedly installed on one side of the rotating disk 33, and an arc-shaped clamping block 36 is fixedly connected to the movable end of the hydraulic rod 35. The rotating assembly 3 also includes a servo motor 38, and the output shaft of the servo motor 38 is fixedly connected to one side of the rotating disk 33.

[0031] During specific implementation: when the slender shaft is inserted into the insertion hole 37 in the docking seat 34, the hydraulic rod 35 is started to push the two arc-shaped clamping blocks 36 to slowly approach each other so as to clamp and fix one end of the slender shaft. The hydraulic rod 35 is convenient for controlling the accuracy to prevent the slender shaft from being affected. Then the servo motor 38 is started to drive the turntable 33 to rotate, thereby driving the slender shaft to rotate.

[0032] All electrical equipment in this solution are powered by an external power supply.

[0033] Working principle: By twisting the anti-skid rotating ring 27 to rotate, the screw rod 26 is driven to rotate. The rotation of the screw rod 26 will prompt the first nut block 24 to move forward along the screw rod 26. The first nut block 24 will then drive the assembly ring 22 to rotate through the protruding block 23. The rotation of the assembly ring 22 will prompt the positioning block 28 to perform a circular motion as a whole. As the positioning block 28 moves, the sliding rod 29 will slide inside it, slowly making the three rollers 210 move closer to the middle center of the circle, thereby clamping and fixing the slender shaft. 0 can roll, so when the slender shaft is clamped, the slender shaft can also rotate, which is convenient for adapting to slender shafts of different diameters and spraying coolant for cooling during processing. When the slender shaft is inserted into the plug hole 37 in the docking seat 34, the hydraulic rod 35 is started to push the two arc-shaped clamping blocks 36 to slowly approach so as to clamp and fix one end of the slender shaft. The hydraulic rod 35 is convenient for controlling the accuracy to prevent the slender shaft from being affected. Then the servo motor 38 is started to drive the turntable 33 to rotate, thereby driving the slender shaft to rotate.
