[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0014] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Please refer to Figures 1-10 An embodiment of this utility model provides a finishing fixture for a fuel inlet, characterized in that it includes: Mounting base 1 has a clamping shaft 11 fixedly installed on one side and a threaded blind hole 12 coaxial with the clamping shaft 11 on the other side. The threaded blind hole 12 is adapted to the external thread of the fuel interface 5. The support component 2 is detachably fixed on the side of the mounting base 1 away from the clamping shaft 11, and is used to support the periphery of the part of the fuel interface 5 that protrudes from the threaded blind hole 12. The tip 3 is located on the side of the support component 2 away from the mounting base 1, and is used to press the clamping ring 52 of the fuel interface 5 into the closing part 51. The closing component 4 is located directly below the closing portion 51 of the fuel inlet 5 and is used to press the closing portion 51 to complete the closing.

[0016] In this embodiment, when closing the fuel inlet 5, first, the clamping shaft 11 of the mounting base 1 is installed on the machine tool chuck. Then, the external thread 54 of the fuel inlet 5 is screwed into the threaded blind hole 12 until tightened. The mounting base 1 and the support assembly 2 are then fixed together. Next, the center point 3 is installed on the lathe tailstock. The center point 3 is used to press the clamping ring 52 of the fuel inlet 5 into the closing portion 51, and the fuel inlet 5 is clamped and positioned. Then, the lathe is started, and the spindle is kept at a low speed. The closing assembly 4 is slowly fed in. When the deformation of the closing portion 51 is sufficient to prevent the clamping ring 52 from being pushed out of the part by the spring 53, the lathe tailstock is operated to retract the center point 3, and the closing assembly 4 is slowly fed in again to complete the closing work. This closing fixture does not damage the parts during processing, is simple and efficient to operate, and produces products with high consistency.

[0017] In a preferred embodiment, such as Figures 3-5 As shown, the support assembly 2 includes a support member 21 and screws 22. The support member 21 is located on the side of the mounting base 1 away from the clamping shaft 11. The support member 21 has a support hole 23 coaxial with the clamping shaft 11. Its inner diameter is clearance-fitted with the outer diameter of the portion of the fuel interface 5 extending out of the threaded blind hole 12. The support member 21 has several countersunk through holes 24 on the outer periphery of the support hole 23. The mounting base has threaded holes 13 corresponding to the countersunk through holes 24. Each countersunk through hole 24 is provided with a screw 22 that is threadedly connected to the corresponding threaded hole 13.

[0018] In this embodiment, when installing the support component 2, the front end of the fuel interface 5 passes through the support hole 23, so that the support component 2 can support and protect the fuel interface 5. Then, the screw 22 passes through the countersunk hole 24 and is screwed into the threaded hole 13 until it is tightened, so that the fixation is reliable. The processing does not damage the parts, the operation is simple, and the product consistency is high.

[0019] In a preferred embodiment, such as Figure 6 As shown, the tip 3 includes a tip seat 33. One end of the tip seat 33 is fixedly connected to a tip head 31 via a variable diameter section 32. The end face of the tip head 31 that contacts the fuel interface 5 is flat. The outer diameter of the tip head 31 is not greater than the inner diameter of the end hole 55 of the fuel interface 5, so that the tip head 31 can be inserted into the fuel interface and press the clamping ring 52 into the closing part 51. The processing is convenient and quick, and the product consistency is improved.

[0020] In a preferred embodiment, such as Figure 7 and Figure 8As shown, the closing assembly 4 includes a cutter bar 41, and a closing die 42 extending upward is fixedly provided at the top end of the cutter bar 41. A forming extrusion part 43 is fixedly provided at the top end of the closing die 42. The side of the forming extrusion part 43 near the support assembly 2 is a vertical extrusion end face 44. The top end of the extrusion end face 44 is inclined away from the support assembly 2 to form an extrusion slope 45.

[0021] In this embodiment, when using the closing assembly 4, the closing die 42 needs to be fed in slowly so that the extrusion slope 45 on the forming extrusion section 43 first contacts the part to be closed 51 and bends it at a certain angle. Then, the extrusion end face 44 contacts the part to be closed 51 at a certain angle and flattens it. When the deformation of the part to be closed 51 is sufficient to prevent the clamping ring 52 from being pushed out of the part by the spring 53, the lathe tailstock is operated to retract the center point 3, and the closing die 42 is fed in slowly to complete the closing work, so that the processing process does not damage the parts and the product consistency is high.

[0022] In a preferred embodiment, such as Figure 7 As shown, the middle part of the closing mold 42 is detachably fixed to the cutter bar 43 by bolts 46. The bottom and top ends of the closing mold 42 are symmetrically provided with forming extrusion parts 43. When the forming extrusion part 43 at one end cannot be used, the closing mold 42 can be flipped over to use the forming extrusion part 43 at the other end, which improves the utilization rate of the closing mold 42 and makes installation and disassembly convenient and quick.
