[0032] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0033] The inventor of the present application finds that after the liquid accumulator is welded with the compressor shell, there is still a mounting process of a rubber ring and a clamp for fixing the liquid accumulator, which requires a certain installation gap between the liquid accumulator and the compressor shell before the rubber ring and the clamp are mounted. At present, after the bottom elbow of the liquid accumulator is welded with the compressor shell, the liquid accumulator and the compressor shell need to be manually pried apart to form an installation gap between the liquid accumulator and the compressor shell. However, the size of the installation gap is uncontrollable. If the gap is too small, it is not easy to install the rubber ring. If the gap is too large, it is not easy to install the clamp, and the welding position of the bottom elbow of the liquid accumulator and the compressor shell is prone to cracking. The embodiments of the present application provide a liquid accumulator installation gap adjusting device which can facilitate the formation of the installation gap and make the size of the installation gap controllable.

[0034] Please refer to Figures 1-4 The liquid accumulator installation gap adjusting device provided by the embodiments of the present application comprises a base 1, a driving assembly 2 and a clamp 3. The clamp 3 is provided with two adjusting plates 31 at the front end. The driving assembly 2 and the clamp 3 are arranged on the base 1. The driving assembly 2 is connected with the clamp 3 to drive the two adjusting plates 31 of the clamp 3 to move closer to each other or farther away from each other. When the two adjusting plates 31 move closer to each other, they extend into the liquid accumulator and the compressor shell. By moving farther away from each other, the liquid accumulator and the compressor shell are pried apart to keep a certain installation gap therebetween.

[0035] Under the driving action of the driving assembly 2, the two adjusting plates 31 move closer to each other and abut. At this time, the two adjusting plates 31 can extend into the liquid accumulator and the compressor shell after welding. When the two adjusting plates 31 move farther away from each other, the liquid accumulator and the compressor shell can be pried apart.

[0036] In the process of using the liquid accumulator installation gap adjusting device, the driving assembly 2 is first started to drive the two adjusting plates 31 to move closer to each other and abut. Then, the two adjusting plates 31 extend into the liquid accumulator and the compressor shell after welding. Subsequently, the driving assembly 2 is started again to drive the two adjusting plates 31 to move farther away from each other. At this time, the two adjusting plates 31 can pry apart the liquid accumulator and the compressor shell to form an installation gap. Compared with the installation gap formed manually, the size of the installation gap is more controllable, and the labor intensity of the workers is also reduced.

[0037] In the embodiments, the clamp 3 comprises first movable rods 32 and second movable rods 33. The number of the first movable rods 32 and the second movable rods 33 is both two. The first ends of the two first movable rods 32 are hingedly connected with the driving assembly 2. The second ends of the two first movable rods 32 are respectively hingedly connected with the first ends of the two second movable rods 33. The two adjusting plates 31 are arranged at the second ends of the two second movable rods 33. The two second movable rods 33 are respectively rotatably connected with the base 1.

[0038] The first movable rod 32 and the second movable rod 33 each have a first end and a second end, the two second movable rods 33 coincide with the rotation connection points of the base 1, and the two adjusting plates 31 are respectively arranged at the second ends of the two second movable rods 33.

[0039] When the driving assembly 2 is started, the driving assembly 2 can drive the second movable rod 33 to move through the first movable rod 32, so that the two adjusting plates 31 arranged on the second movable rod 33 are close to or away from each other.

[0040] The installation gap adjusting device further comprises a limiting piece 331 for limiting the distance between the two adjusting plates 31 when they are away from each other.

[0041] In the case that the two adjusting plates 31 are away from each other, the limiting piece 331 can limit the distance between the two adjusting plates 31, so that the size of the installation gap formed between the liquid accumulator and the compressor shell is controllable.

[0042] In the embodiment, the limiting piece 331 is arranged on one of the second movable rods 33, and when the two adjusting plates 31 are away from each other to a set distance, the limiting piece 331 can abut against the other second movable rod 33.

[0043] By arranging the limiting piece 331 on one of the second movable rods 33, the limiting piece 331 can abut against the other second movable rod 33 during the process that the two adjusting plates 31 are away from each other, thereby playing a limiting role, and further making the size of the installation gap formed by the two adjusting plates 31 when they are away from each other controllable. When the installation gap adjusting device is used to separate a plurality of groups of liquid accumulators and compressor shells, the size of the installation gap formed between each group of liquid accumulators and compressor shells is also substantially consistent, thereby ensuring product consistency.

[0044] The base 1 is provided with a positioning column 11, and the two second movable rods 33 are rotatably connected with the positioning column 11 in an X shape, and the two first movable rods 32 are rotatably connected at the first ends in a V shape.

[0045] The second movable rod 33 is rotatably connected with the positioning column 11 at a position close to the second end of the second movable rod 33, so as to be rotatably connected with the base 1. The limiting piece 331 is closer to the driving assembly 2 than the positioning column 11, so that when the two adjusting plates 31 are away from each other, the limiting piece 331 can abut against the other second movable rod 33 to limit the opening angle of the two adjusting plates 31.

[0046] In the embodiment, the limiting piece 331 is a bolt, the end portion of the bolt extends to between the two second movable rods 33 after penetrating through one of the second movable rods 33, and the length of the bolt extending into the two second movable rods 33 is adjusted by rotating the bolt.

[0047] In the case where the limiting member 331 is a bolt, a threaded hole is formed on one of the second movable rods 33, the bolt is threadedly connected with the threaded hole, and the end of the bolt extends to between the two second movable rods 33 through the threaded hole. When the two adjusting plates 31 are away from each other, the end of the bolt can abut against the other second movable rod 33, thereby playing a limiting role.

[0048] In other embodiments, the limiting member 331 can also be a limiting column, which is fixed to the surface of one of the second movable rods 33 facing the other second movable rod 33. When the two adjusting plates 31 are away from each other, the limiting column can also abut against the other second movable rod 33, thereby playing a limiting role.

[0049] In this embodiment, the driving assembly 2 includes a driving member 21 and a guide rod 22. The driving member 21 is arranged on the base 1, and the two ends of the guide rod 22 are respectively connected to the clamp 3 and the driving member 21. The guide rod 22 is in sliding fit with the base 1.

[0050] The guide rod 22 has opposite first and second ends. The driving member 21 is connected to the first end of the guide rod 22 to drive the guide rod 22 to move along the length direction of the guide rod 22. The first ends of the two first movable rods 32 are hingedly connected to the second end of the guide rod 22.

[0051] When the driving member 21 is started, the driving member 21 drives the guide rod 22 to move along the length direction of the guide rod 22. The guide rod 22 drives the second movable rod 33 to move through the first movable rod 32, so that the two adjusting plates 31 arranged on the second movable rod 33 are close to or away from each other.

[0052] In this embodiment, the base 1 is provided with a guide block 12. A guide hole 121 is formed in the guide block 12. The guide rod 22 is slidably arranged in the guide hole 121.

[0053] The guide rod 22 is in shape matching with the guide hole 121. When the driving member 21 drives the guide rod 22 to move along the length direction of the guide rod 22, the guide rod 22 can slide in the guide hole 121. The guide hole 121 can play a limiting role on the guide rod 22, so that the guide rod 22 always stably moves along the length direction of the guide rod 22 and is not easy to deviate.

[0054] In other embodiments, a sliding groove is formed in the base 1. The sliding groove is formed in the same direction as the length direction of the guide rod 22. A sliding block is arranged on the guide rod 22 and in sliding fit with the sliding groove. When the driving member 21 drives the guide rod 22 to move along the length direction of the guide rod 22, the sliding block slides in the sliding groove, thereby playing a limiting role on the guide rod 22, so that the guide rod 22 always stably moves along the length direction of the guide rod 22.

[0055] In this embodiment, the driving member 21 is a cylinder, and the base 1 is further provided with a pneumatic valve 13 connected with the cylinder.

[0056] The pneumatic valve 13 can be manually operated, and the cylinder movement can be conveniently controlled through the pneumatic valve 13, thereby driving the guide rod 22 to move along the length direction of the guide rod 22.

[0057] In other embodiments, the driving member 21 can also be other driving sources, for example, the driving member 21 is an electric push rod or a linear motor, which can also drive the guide rod 22 to stably move along the length direction of the guide rod 22.

[0058] In this embodiment, the base 1 is further provided with a handle 14, and the handle 14 is close to the pneumatic valve 13.

[0059] By providing the handle 14 on the base 1 and making the handle 14 close to the pneumatic valve 13, the operator can hold the handle 14 with one hand and press the pneumatic valve 13 with the thumb to control the cylinder movement when using the tool, which greatly improves the convenience of operation.

[0060] Please refer to Figure 5 The embodiment of the application also provides a use method of the liquid accumulator installation gap adjusting device, and the use method comprises the following steps:

[0061] Step S1, drive the two adjusting plates 31 to approach each other through the driving assembly 2.

[0063] Step S2, extend the two adjusting plates 31 between the liquid accumulator and the compressor shell.

[0064] In this step, since the two adjusting plates 31 approach each other and abut, the two adjusting plates 31 can be easily extended between the welded liquid accumulator and the compressor shell.

[0065] Step S3, drive the two adjusting plates 31 to move away from each other through the driving assembly 2 to support the liquid accumulator and the compressor shell, so that a certain installation gap is maintained between the two.
