Description

Technical Field

[0001] The utility model belongs to the field of compressor processing, and in particular relates to a compressor shell welding tool. Background Art

[0002] Compressors, as equipment that can compress gas into high-pressure gas, are used in industrial manufacturing, refrigeration and air conditioning, oil and gas, chemicals and pharmaceuticals, and other fields. Compressors have high requirements for the sealing of the casing, which is directly related to its working efficiency, safety, and reliability. When welding the top cover, bottom cover, intake duct, exhaust duct, sight glass and other components of the compressor casing, their sealing performance must be ensured. If the sealing is poor, it will lead to unstable operation of the compressor, air leakage and other problems. In addition, most of the components that need to be welded are arranged perpendicular to the casing. In order to ensure their welding accuracy and sealing, specific tooling is required for fixing them, and then the top cover, bottom cover, intake duct, exhaust duct, sight glass and other components are welded.

[0003] For example, application number CN202420350036.1 discloses a positioning tool for an air-conditioning compressor housing. This tool positions the compressor housing and welds the top and bottom covers. However, when welding interfaces such as the intake and exhaust ducts and the sight glass, the welding angle affects the bottom view of the components, potentially resulting in poor welding and affecting production efficiency. Therefore, a welding tool is needed that facilitates the welding of components that are perpendicular to the housing. Utility Model Content

DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, the utility model discloses a compressor housing welding tool, comprising:

[0029] The housing 1 has a welding port 12 for connecting with a welding member 11;

[0030] The fixed base 2 has a supporting slide rail 3 and a limiting slide rail 4. The supporting slide rail 3 is provided with a sliding supporting portion 31 for supporting the shell 1. The limiting slide rail 4 is provided with a sliding limiting portion 41 for limiting the rotation of the shell 1. The shell 1 is sleeved on the outside of the limiting slide rail 4 and placed above the supporting slide rail 3. The limiting portion 41 passes through the shell 1 and is connected thereto to limit the rotation of the shell 1.

[0031] The shell 1 is placed on the support part 31 and is sleeved on the outside of the limiting slide rail 4 so that the axis of the compressor shell 1 is parallel to the horizontal plane. The rotation of the compressor shell 1 is controlled by the limiting part 41, which avoids dead angles during welding and improves the stability during welding.

[0032] The welding parts 11 include but are not limited to an air intake pipe, an exhaust pipe, and a sight glass.

[0033] In order to facilitate the support part 31 to slide on the support rail 3, the bottom of the support part 31 has a support groove 311 that matches the support rail 3. In order to improve the stability of the placement of the shell 1, the top of the shell 1 has a V-shaped groove 312 that matches the shell 1. When the shell 1 is placed on the support part 31, the shell 1 can be dragged to move along the support rail 3.

[0034] In some embodiments of the present invention, the limiting rail 4 is fixedly connected to the fixing seat 2, and the limiting portion 41 slides on the limiting rail 4, such as Figure 1As shown in FIG2 , the limiting portion 41 may adopt the following structure: the longitudinal cross-section of the limiting portion 41 is M-shaped, with a first limiting groove 411 at the bottom thereof matching the limiting rail 4, and a pin body 412 at the top thereof matching the welding port 12, wherein the outline of the pin body 412 matches the outline of the welding port 12; wherein the pin body 412 is detachably connected to the limiting portion 41. The shell 1 is placed on the outside of the limiting rail 4, the lower part of the shell 1 is supported by the support portion 31, the limiting portion 41 slides on the limiting rail 4, the limiting portion 41 is moved to the position to be welded, the pin body 412 is passed through the welding port 12 and connected to the limiting portion 41, at which point the rotation of the shell 1 is restricted, and then the welding part 11 is inserted into the pin body 412 and aligned, and the shell 1 can be dragged to move along the supporting rail 3 and the limiting rail 4, and the angle of the shell 1 during the movement can be kept constant.

[0035] In some embodiments of the present invention, the difference from the above embodiments is that the limiting slide rail 4 is rotatably connected to the fixing seat 2, such as Figure 3 As shown in FIG5 , the centerline of the limiting rail 4 is aligned with the centerline of the housing 1. The limiting portion 41 has a circular longitudinal cross-section, with a second limiting groove 413 at its center that is slidably connected to the limiting rail 4, and a locating pin 414 at its edge that is connected to the housing 1. The housing 1 is placed over the limiting rail 4, with the lower portion of the housing 1 supported by the support portion 31. The limiting portion 41 slides on the limiting rail 4, moving the limiting portion 41 to the appropriate position. The limiting portion 41 is then connected to the housing 1 via the locating pin 414. The weldment 11 interfaces with the weld port 12 through its own structure, such as a boss, slot, or step. When the angle of the housing 1 needs to be changed, the limiting rail 4 can be rotated.

[0036] In order to increase the rotation angle of the housing 1, as Figure 4 As shown, a turntable 42 is connected to one side of the limiting slide rail 4. The turntable 42 is provided on one side of the fixing base 2 and connected to the fixing base 2. The turntable 42 is marked with scales, which can clearly and accurately change the rotation angle of the shell 1.

[0037] In addition, in order to improve the stability of the shell 1 during welding, a limit pin 43 is provided on one side of the fixing seat 2, and the limit slide rail 4 is connected to the fixing seat 2 through the limit pin 43, and a number of evenly distributed sockets 44 matching the limit pins 43 are provided on the side wall of the limit slide rail 4. When the shell 1 is rotated to the required angle, the limit pin 43 passes through the fixing seat 2 and is inserted into the socket 44, which limits the rotation of the shell 1 and improves the stability during welding.

[0038] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
