The following disclosure provides many different embodiments or examples for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or reference letters in the various examples, which have been repeated for purposes of simplicity and clarity and do not in themselves dictate a relationship between the various embodiments and/or arrangements discussed.

Referring to fig. 1, fig. 1 is a schematic cross-sectional view of a compressor tail pipe structure according to an embodiment of the present invention, where the compressor tail pipe structure includes an exhaust pipe 1 and an annular steel seat 2. Referring to fig. 2 and 3, fig. 2 and 3 are schematic diagrams of front and top views of the exhaust pipe, respectively, the outer wall of the exhaust pipe 1 is processed with a plurality of regularly arranged grooves 3 by using a rolling process, and when the exhaust pipe is rolled, the material on the surface of the exhaust pipe 1 is diffused from the side edges of the grooves 3, so that convex teeth 4 protruding out of the surface of the exhaust pipe are formed between adjacent grooves 3. The inner diameter of the annular steel seat 2 is larger than the outer diameter of the exhaust pipe 1, the annular steel seat 2 is sleeved on the periphery of the exhaust pipe 1, and the top end of the convex tooth 4 is tightly attached to the inner wall of the annular steel seat 2, as shown in fig. 1.

Preferably, the groove 3 is linear in shape and parallel to the axial direction of the exhaust pipe 1, which is designed for ease of machining.

Preferably, the height of the protruding teeth 4 protruding from the surface of the exhaust pipe 1 is 0.05-0.25 mm, and the most preferred embodiment is 0.2 mm.

The application provides an annular steel seat 2, as the connection auxiliary structure similar with the compressor material, is connected with the compressor through annular steel seat 2 and can make to be connected more firmly, and the welding cost is lower. The inner diameter of the annular steel seat 2 is larger than the outer diameter of the exhaust pipe 1, namely, a gap (generally about 0.2 mm) is reserved between the outer wall of the exhaust pipe 1 and the inner wall of the annular steel seat 2. The solder has fluidity during welding, can flow into the clearance, fills the clearance, makes the lateral wall of blast pipe 1 and annular steel seat 2 be connected to be favorable to the welding more firmly, both ends welding method when being more firm than ordinary prior art welding auxiliary structure.

However, due to the gap and the small gap, the preassembly of the common exhaust pipe and the annular steel seat 2 is not easy to align, and the gap is easy to be uneven, so that the solder is unevenly filled, as shown in fig. 4, fig. 4 is a schematic cross-sectional structure diagram of the annular steel seat 2 directly welded on the common exhaust pipe, and the phenomenon of uneven filling of the solder can be seen.

Therefore, according to the exhaust pipe, the outer wall of the exhaust pipe 1 is processed with the plurality of regularly arranged grooves 3 by using a rolling process, and when the exhaust pipe is rolled, the material on the surface of the exhaust pipe 1 is diffused from the side edges of the grooves 3, so that the convex teeth 4 protruding out of the surface of the exhaust pipe are formed between the adjacent grooves 3. When the annular steel seat 2 is sleeved on the periphery of the exhaust pipe 1, the top end of the convex tooth 4 is tightly attached to the inner wall of the annular steel seat 2, so that the exhaust pipe 1 and the annular steel seat 2 are more accurately aligned and positioned, and the solder is filled more uniformly, as shown in fig. 5, fig. 5 is a cross-sectional structural diagram of the compressor exhaust tail pipe structure after a rolling process is used (fig. 5 is a cross section of a part cut through the solder). The groove 3 is used for accommodating solder, so that the exhaust pipe 1 is connected with the side wall of the annular steel seat 2, and the design is also more favorable for saving the solder.

In conclusion, the application provides a compressor tail pipe structure, the annular steel seat 2 is arranged outside the exhaust pipe 1 and connected with the compressor, the improvement of welding firmness and the reduction of welding cost are facilitated, and the grooves 3 and the convex teeth 4 are machined in the outer wall of the exhaust pipe 1 through a rolling process, so that the exhaust pipe 1 and the annular steel seat 2 are aligned and positioned more accurately, the solder is filled more uniformly, and the solder is saved more.
