[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0020] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices consistent with some aspects of the present application as detailed in the appended claims.

[0021] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those of ordinary skill in the field to which this utility model belongs. The words such as "a" or "an" used in the specification and claims of this application do not denote a limitation of quantity either, but mean that there is at least one. "Plurality" includes two, which is equivalent to at least two. Words such as "comprising" or "including" mean that the elements or objects appearing before "comprising" or "including" cover the elements or objects listed after "comprising" or "including" and their equivalents, and do not exclude other elements or objects. Words such as "connected" or "coupled" are not limited to physical or mechanical connections, and may include electrical connections, whether direct or indirect. The singular forms of "a", "the" and "said" used in the specification and appended claims of this application are also intended to include the plural forms unless the context clearly dictates otherwise. It should also be understood that the term "and / or" used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0022] Please refer specifically to Figures 2 - 4 , a batch welding base for a compressor exhaust pipe assembly, comprising a bottom support 1, four columns 2, and a positioning plate 3 adapted to the bottom support 1. The columns 2 are installed at the four corners of the bottom support 1, the positioning plate 3 is installed on the columns 2, and a plurality of through holes 301 arranged at equal intervals are provided on the positioning plate 3. The through holes 301 penetrate through both end faces of the positioning plate 3. A connecting column 201 is provided at the top of the column 2. The connecting column 201 and the column 2 are of an integral structure. A thread is provided on the connecting column 201. A nut 4 is installed on the connecting column 201. The connecting column 201 is adapted to be inserted through the through holes 301 located at the four corners of the positioning plate 3. The bottom end of the column 2 is connected to the bottom support 1 by a welding process, and the top end is connected to the positioning plate 3 by the nut 4.

[0023] A plurality of jacks 101 are provided on the bottom support 1 and are arranged at equal intervals. The jacks 101 do not penetrate through the bottom support 1. The jacks 101 correspond to the through holes 301. The bottom of the copper pipe will be inserted into the jacks 101. The jacks 101 play a role in limiting the position to prevent the position of the copper pipe inserted onto the bottom support 1 from shifting.

[0024] It further includes a plurality of washers 5. The washers 5 are sleeved on the connecting column 201 and are located below the positioning plate 3. The function of the washers 5 is to change the height of the positioning plate 3, so as to adapt to copper pipes of different heights. Different numbers of washers 5 can be padded above the positioning plate 3 according to actual needs. The height of each washer 5 is adapted to the height of the copper pipe.

[0025] The diameter of the column 2 is larger than that of the connecting column 201, so as to limit the positioning plate 3 and make the washer 5 restricted above the column 2.

[0026] The shapes of the bottom support 1 and the positioning plate 3 are one of square or rectangle. In this embodiment, the shapes of both the bottom support 1 and the positioning plate 3 are square.

[0027] The present utility model is a batch welding base 1 for a compressor exhaust pipe assembly, and its working principle is described in conjunction with the accompanying drawings:

[0028] First, adjust the relative distance between the bottom support 1 and the positioning plate 3 according to the height of the copper pipe, which can be achieved by increasing or decreasing the washer 5. Install the copper pipe in the through hole 301, insert the bottom of the copper pipe into the jack 101, and put on the flange. After a batch of copper pipes are assembled, batch welding can be carried out by using welding wire or brazing equipment.

[0029] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
