[0002] Refrigerator piping mainly includes refrigeration pipes and dehumidification pipes. Refrigeration pipes are the main pipes in the refrigerator, used for refrigerant circulation. They change the refrigerant's state through compression and expansion to produce a cooling effect. Dehumidification pipes are located between the freezer and refrigerator compartments, used to balance moisture and temperature, preventing moisture buildup inside the refrigerator. Refrigerator pipes need to be clamped for easy installation and maintenance; a refrigerator pipe clamping device is required when clamping these pipes.

[0003] However, existing clamping devices have a low degree of automation and most cannot automatically feed materials. They require manual movement of the pipe to the clamping point before being clamped by the clamping mechanism, resulting in low clamping efficiency and significantly reducing work efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a clamping device for refrigerator pipe fittings, including a feeding rack 1 with an inclined top, a clamping component 2 at the top of the feeding rack 1 near the bottom, two limiting plates 9 symmetrically arranged along its length on the feeding rack 1, an opening 8 between the two limiting plates 9 on the feeding rack 1, and an arc-shaped groove 7 for pipe fitting positioning at the position directly below the clamping component 2 on the feeding rack 1, and a transmission component 6 and a feeding component are provided inside the feeding rack 1, the transmission component 6 and the feeding component cooperate to realize the intermittent automatic feeding of the pipe fitting to be clamped.

[0017] In this embodiment, the feeding rack 1 is designed in the shape of a right trapezoid, and the clamping component 2 is set at the lower end of the feeding rack 1. The distance between the two limiting plates 9 on the feeding rack 1 matches the length of the pipe to be clamped. A rolling channel for the pipe to be clamped is formed between the two limiting plates 9. With the cooperation of the transmission component 6 and the feeding component, the pipe to be clamped can be automatically fed to the clamping component 2 at intervals for clamping.

[0018] Specifically, the clamping assembly 2 includes a gantry frame 21 mounted on top of the feeding rack 1. A cylinder 22 is mounted on top of the gantry frame 21. A sliding plate 24 is fixedly connected to the piston rod 23 of the cylinder 22. A cutter 25 is mounted on the bottom of the sliding plate 24. When the pipe to be clamped moves along the rolling channel between the two limiting plates 9 to the arc groove 7, it will stop on the arc groove 7. Then, the cylinder 22 on the gantry frame 21 is activated. The piston rod 23 of the cylinder 22 extends and drives the sliding plate 24 to move down inside the gantry frame 21. As the sliding plate 24 moves, the cutter 24 at the bottom of the sliding plate 24 clamps the pipe located in the arc groove 7. After the clamping work is completed, the cylinder 22 drives the cutter 24 to reset. The personnel can then remove the cut pipe and proceed with the next clamping work. During the pipe clamping process, in order to ensure the stability of the pipe, the clamping assembly 2 also includes pressure blocks 27 set on both sides of the cutter 25. The pressure blocks 27 are connected to the sliding plate 24 through the damping spring 26. In the stopped state, the pressure blocks 27 are lower than the cutter 24. When the cutter 24 moves down under the action of the cylinder 22 to perform the clamping work, the pressure blocks 27 contact the pipe to be clamped first. As the cylinder 22 continues to extend, the pressure blocks 27 compress the damping spring 26, thereby pressing the pipe to be clamped tightly. The damping spring 26 adopts a spring structure with damping elements, which can play a buffering role and further ensure the stability of the pipe during the clamping work.

[0019] Specifically, the feeding assembly includes two rotating rods 3 rotatably mounted on the feeding frame 1. Several distributing plates 5 are arranged around the axis of the rotating rods 3 via rotating rollers 4. The two rotating rods 3 can be synchronously driven by a chain 614 on a sprocket 613. The transmission assembly 6 includes a motor 62 mounted on the feeding frame 1 via a mounting plate 61. A cam 64 is mounted on the output end of the motor 62 via a rotating shaft 63. The transmission assembly 6 also includes a fixing block 65 fixed to the inner wall of the feeding frame 1. A connecting rod 66 is rotatably connected to the end of the fixing block 65. A locking block 67 is fixedly connected to the end of the connecting rod 66. A ratchet 68 that cooperates with the locking block 67 is provided on one of the rotating rods 3. A pressing rod 69 that cooperates with the cam 64 is fixedly connected to the connecting rod 66. A fixing block 610 is provided on the mounting plate 61 via a fixing block 612. A spring 611 is provided on the fixing block 610, and one end of the spring 611 is connected to the connecting rod 66.

[0020] When cutting is required, the pipe fitting is placed between the limiting plates 9, and the motor 62 is turned on. The motor 62 rotates, driving the rotating shaft 63 to rotate. The rotating shaft 63 rotates, driving the cam 64 to rotate. The cam 64 rotates and contacts the lower pressure rod 69. The lower pressure rod 69 moves downward, causing the connecting rod 66 to rotate on the fixed block 65. The rotation of the connecting rod 66 stretches the spring 611. The rotation of the connecting rod 66 causes the locking block 67 to rotate. After the locking block 67 moves away from the ratchet 68, the weight of the pipe fitting causes the material distribution plate 5 to rotate on the rotating roller 4. The rotation of the rotating roller 4 drives the rotating rod 3 to rotate. The rotation of the rotating rod 3 drives the ratchet 68 to rotate. The locking slots on the ratchet 68 are evenly divided into four parts, corresponding one-to-one with the position of the material distribution plate 5. When a pipe fitting moves downward, the cam 64 moves away from the lower pressure rod 69, and the spring 611 uses its elasticity to return the connecting rod 66 to its original position. The return of the connecting rod 66 to its original position causes the locking block 67 to move closer to the ratchet 68. At this point, the latch on ratchet 68 engages with the locking block 67, and one pipe fitting completes its transport and movement. The downward-moving pipe fitting moves to the distribution plate 5 below the gantry frame 21. As the material continues to move through the above steps, the distribution plate 5 rotates, driving the rotating roller 4 and rotating rod 3 to rotate. The rotating rod 3 rotates, driving the sprocket 613 to rotate. The sprocket 613 rotates in conjunction with the chain 614 on it. The higher distribution plate 5 sends down another pipe fitting, and the lower distribution plate 5 sends the pipe fitting into the arc groove 7. It is then cut by the clamping assembly 2. When the sliding plate 24 moves downward, the damping spring 26 and the pressure block 27 on it also move downward. The pressure block 27 helps to fix the pipe fitting, ensuring better cutting. After cutting is completed, the sliding plate 24 moves back to its original position. At this time, the distribution plate 5 removes the pipe fitting cut by the arc groove 7, and the new pipe fitting enters the arc groove 7, repeating the new cutting work, thus improving the clamping efficiency.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
