[0002] In the manufacturing process of a compressor, a liquid storage tank assembly needs to be installed on the shell of the compressor. The bent pipe of the liquid storage tank assembly needs to be welded to the injection pipe on the shell. The liquid storage tank body of the liquid storage tank assembly is fixedly installed on the shell through a bracket. The injection pipe is in communication with the liquid storage tank body through the bent pipe. The liquid storage tank body of the traditional structure is directly fixed on the bracket by a clamp. However, there is a problem of excessive noise in the use process. In view of this, a bracket with a "several" character structure is provided in the related art, and a damping member is arranged between the bracket and the liquid storage tank body. The liquid storage tank body is fixed on the bracket by a clamp to eliminate the noise. However, a problem is caused that the liquid storage tank body cannot be fixed on the bracket by the clamp and the damping member until the bent pipe is welded to the injection pipe. At the same time, the structure of the "several" character bracket cannot effectively constrain the position of the liquid storage tank body. Therefore, during the welding process of the bent pipe and the injection pipe, the relative position of the liquid storage tank body and the bracket cannot be guaranteed, and the consistency of the product after welding is low.

[0036] The embodiments of the present application will be described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.

[0037] As Figures 1-7As shown, the present invention provides a welding fixture 2 for a liquid storage tank, used to fix the tank body 200 of the liquid storage tank assembly to a bracket 1. The bracket 1 includes a mounting section 11, with a folding section 12, a mating section 13, and an extension section 14 connected to both ends of the mounting section 11. The mounting section 11 is fixedly connected to the compressor housing 100, and the curvature of the mounting section 11 corresponds to the curvature of the compressor housing 100, so that the mounting section 11 fits against the compressor housing 100. The folding section 12 is connected to both ends of the mounting section 11, and the folding section 12 extends in a direction away from the compressor housing 100. The mating section 13 is set at an angle to the folding section 12, and the curvature of the mating section 13 corresponds to the curvature of the tank body 200 of the liquid storage tank assembly, and the mating section 13 is used to fit against the tank body 200. Extension section 14 connects to the end of mating section 13 furthest from folding section 12 and is angled or perpendicular to mating section 13. During the formal installation of tank body 200 onto bracket 1, extension section 14 provides mounting points for relevant fasteners or connectors, such as using clamps to install tank body 200 onto bracket 1, with both ends of the clamps attached to the two extension sections 14 respectively. The liquid storage tank assembly includes tank body 200 and elbow 300. A spray pipe is connected to the compressor housing 100, and the spray pipe connects to elbow 300 and communicates with tank body 200 through elbow 300. After the spray pipe and elbow 300 are connected, they are welded. After welding, tank body 200 is formally installed onto bracket 1 using clamps. During the welding process of spray pipe and elbow 300, liquid storage tank welding fixture 2 is used to fix tank body 200 onto bracket 1 to ensure product consistency after welding. The welding fixture 2 for the liquid storage tank includes a fixing part 21, a protective plate 22, and an insert 23. The fixing part 21 is used to position and fix the tank body 200. The protective plate 22 and the insert 23 are both fixedly connected to one side of the fixing part 21 and are spaced apart along the circumference of the fixing part 21. The fixing part 21 can be a split structure or an integral structure, with the protective plate 22 and the insert 23 fixedly connected, so that the relative positions of the protective plate 22 and the insert 23 on the fixing part 21 remain unchanged. For example, the fixing part 21 can be an integral ring structure, with the protective plate 22 and the insert 23 fixedly connected or integrally connected to the fixing part 21; or the fixing part 21 can include multiple segments, with the ends of the multiple segments fixedly connected to form a ring structure, and one or more of the multiple segments are fixedly connected or integrally connected with the protective plate 22 and / or the insert 23; or the fixing part 21 can be configured as a structure with multiple connection points, with the multiple connection points respectively used to connect the protective plate 22 or the insert 23. In this embodiment, the fixing part 21 is preferably an annular structure, and the inner sidewall of the fixing part 21 is used to fit against the outer sidewall of the tank 200. Both the protective plate 22 and the insert 23 extend in a direction parallel to the extension line of the axis of the fixing part 21.Along the circumference of the fixing part 21, both the protective plate 22 and the insert 23 are arc-shaped structures. The inner wall of the protective plate 22 is used to fit against the outer wall of the tank 200, and the insert 23 is used to fit against the side of the mating section 13 away from the tank 200, thus ensuring that the mating section 13 is tightly fitted against the outer wall of the tank 200. By having the fixing part 21 and the protective plate 22 fit against the inner wall of the tank 200, and the insert 23 fit against the side of the mating section 13 of the bracket 1 away from the tank 200, the mating section 13 is tightly fitted against the outer wall of the tank 200. Therefore, during the welding process between the bend 300 and the spray pipe, the position of the tank 200 on the bracket 1 remains unchanged, resulting in higher product consistency after welding and improved weld joint quality. After welding, the liquid storage tank welding fixture 2 can be quickly removed to facilitate subsequent formal assembly operations, which helps improve production efficiency.

[0038] Furthermore, two inserts 23 are provided, and the two inserts 23 respectively fit into the two mating sections 13. Under the action of the two inserts 23, the two mating sections 13 are tightly attached to the outer wall of the tank body 200, which further ensures that the tank body 200 will not detach from the support 1 during the welding process.

[0039] Specifically, please refer to Figure 5 As shown, one end of the insert 23 connected to the fixing part 21 protrudes radially inward along the fixing part 21, that is, protrudes towards the center of the fixing part 21, and forms a limiting step 231. The limiting step 231 is used to fit against the upper end of the mating section 13. By setting the limiting step 231, the position of the liquid storage tank welding fixture 2 can be changed, and the position of the liquid storage tank welding fixture 2 can be further adjusted by changing the height of the limiting step 231, so as to avoid obstruction or interference to the surrounding structure.

[0040] Please refer to Figures 5-7 and combined Figure 4 As shown, the insert 23 has a first limiting wall 232 on one side of the fixing part 21 along the circumference, which is used to fit with the folded section 12. The insert 23 has a second limiting wall 233 on the other side of the fixing part 21 along the circumference, which is used to fit with the extension section 14. That is, the insert 23 fits with the corresponding folded section 12 and extension section 14 on both sides of the fixing part 21 through the first limiting wall 232 and the second limiting wall 233, respectively, thus limiting the insertion 23 along the circumference of the fixing part 21 and preventing rotation of the liquid storage tank welding fixture 2, thereby improving the positioning accuracy of the liquid storage tank welding fixture 2 on the tank body 200 and the bracket 1. In this embodiment, both inserts 23 fit with their respective folded sections 12 and extension sections 14 on both sides to further improve the positioning effect of the liquid storage tank welding fixture 2.

[0041] Alternatively, please refer to Figure 4As shown, the thickness of the insert 23 is greater than the thickness of the mating section 13. When the insert 23 and the mating section 13 are attached, the mating section 13 is tightly attached to the outer side of the tank 200. At this time, the mating section 13 undergoes a certain degree of elastic deformation, and there is friction between it and the outer side of the tank 200 and the insert 23. At the same time, the elastic force of the mating section 13 acts on the insert 23. Setting the thickness of the insert 23 to be greater than the thickness of the mating section 13 can, to a certain extent, reduce the deformation of the insert 23 after it undergoes elastic deformation under the elastic force of the mating section 13. Thus, the mating section 13 can apply sufficient elastic force to the tank 200. Then, through the attachment of the protective plate 22 to the tank 200, the outer side of the tank 200 is reliably attached to the mating section 13. Finally, it ensures that the tank 200 is tightly attached to the support 1, while also ensuring sufficient friction between the tank 200 and the support 1. There is friction between the tank body 200, the protective plate 22, and the mating section 13. The self-weight of the tank body 200 and part of the axial external force borne by the tank body 200 during subsequent assembly or testing can be borne by the support 1 and the liquid storage tank welding fixture 2, thereby avoiding excessive stress on the bent pipe 300 below the tank body 200, which could lead to deformation.

[0042] Optionally, the curvature of the protective plate 22 along the circumference of the fixing part 21 is 90°-150° to ensure that the protective plate 22 has sufficient strength to radially constrain the tank body 200, and at the same time, to a certain extent, to protect the tank body 200 from bumps and scratches. The curvature of the protective plate 22 can be 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145° or 150°. In this embodiment, the curvature of the protective plate 22 is preferably 120°.

[0043] Optionally, the fixing part 21, the protective plate 22 and the insert 23 are integrally formed and connected, and the welding fixture 2 of the liquid storage tank is made of copper, aluminum or iron.

[0044] This embodiment provides a welding method for a liquid storage tank. The welding method utilizes the liquid storage tank welding fixture 2 provided in this embodiment to assist in the welding process. The welding method for the liquid storage tank includes the following steps:

[0045] The bracket 1 is fixedly connected to the housing 100 of the compressor;

[0046] Connect the bend 300 of the liquid storage tank assembly to the injection pipe on the housing 100 of the compressor, and attach the tank body 200 of the liquid storage tank assembly to the mating section 13 of the bracket 1.

[0047] Install the liquid storage tank welding fixture 2, so that the fixing part 21 and the protective plate 22 are attached to the tank body 200, and the insert 23 is attached to the side of the mating section 13 away from the tank body 200 and the mating section 13 is attached tightly to the tank body 200.

[0048] Weld the bend 300 to the spray pipe and remove the welding fixture 2 from the storage tank.

[0049] The bracket 1 is fixedly connected to the compressor housing 100 using bolts or other fasteners. Then, the bent pipe 300 connected to the lower part of the liquid storage tank assembly 200 is connected to the injection pipe on the compressor housing 100. The injection pipe and compressor housing 100 can be welded or threaded. At this point, the bent pipe 300 and the injection pipe are in a pre-connected state. The liquid storage tank assembly 200 is then fitted onto the direct mating section 13. The liquid storage tank welding fixture 2 is installed, ensuring the fixing part 21 and the protective plate 22 are fitted against the pipe body. The insert 23 is aligned with and inserted into the mating section 13 of the bracket 1, ensuring the insert 23 is fitted against the side of the mating section 13 away from the tank body 200, and the mating section 13 is tightly fitted onto the tank body 200. The bent pipe 300 is welded to the injection pipe, and the liquid storage tank welding fixture 2 is removed. Due to the positioning of the liquid storage tank welding fixture 2, the relative position of the bent pipe 300 and the liquid storage tank injection pipe remains unchanged during the welding process, thereby improving the consistency of the welded product and the welding accuracy of the weld joint. After removing the welding fixture 2 from the storage tank, the shock absorber and clamps can be directly assembled with the bracket 1, completing the welding and installation of the storage tank assembly. Using the storage tank welding fixture 2 in this embodiment to assist welding simplifies installation and disassembly, thus improving production efficiency.

[0050] This embodiment provides a compressor in which the liquid receiver assembly is welded to the compressor housing 100 using the liquid receiver welding method described in this embodiment.
