[0029] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. In addition, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0030] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and embodiments.

[0031] Please refer to Figures 1 to 4 , an embodiment of the present utility model provides a part closing tooling, including:

[0032] A base 1, on the top surface of which a positioning groove 11 is provided;

[0033] A fixing component 2, arranged above the positioning groove 11, for fixing the part 6 in the positioning groove 11;

[0034] A bracket 3, fixedly arranged on one side of the base 1, and a first pin hole 31 is axially provided on the bracket 3 along any oil injection port 61 of the part 6;

[0035] A closing component 4, slidably passing through the first pin hole 31, for extruding the oil injection port 61 of the part 6 to close it.

[0036] In this embodiment, for example Figure 1When performing extrusion and closing of each fuel injection port 61 on the shown part 6, first fix the base 1 to the workbench of the hydraulic equipment, then embed the lower part of the part 6 into the positioning groove 11 to position the axial direction of the part, and rotate the part 6 to align any fuel injection port 61 with the closing component 4; then fix the part 6 in the positioning groove 11 through the fixing component 2. At this time, press down the closing component 4 through the hydraulic equipment, and the closing component 4 extrudes the fuel injection port 61 aligned with it for closing treatment. Then unlock the fixing component 2, rotate the part 6 to align another fuel injection port 61 with the closing component 4, and complete the closing treatment according to the above steps, so as to complete the closing treatment of each fuel injection port 61 one by one. Each fuel injection port 61 is extruded and closed by the same closing component 4, ensuring the consistency of the closing of each fuel injection port 61, with convenient operation, good closing effect, and ensuring the consistency of the flow rate of each fuel injection port 61.

[0037] In a preferred embodiment, as Figure 2 and Figure 4 shown, the closing component 4 includes a first pin rod 41 sliding through the first pin hole 31. The top end of the first pin rod 41 is fixedly connected with a limit end cap 42, and the bottom end is threadedly connected with an extrusion head 43. An extrusion groove 44 is opened at the bottom end of the extrusion head 43. The extrusion groove 44 is in a conical shape adapted to the outer contour of the fuel injection port 61. A washer 45 is sleeved on the first pin rod 41 between the first pin hole 31 and the limit end cap 42, and the washer 45 is provided with a variety of different thickness dimensions.

[0038] In this embodiment, before fixing the part 6, rotate the part 6 to align any fuel injection port 61 to be closed and embed it into the extrusion groove 44, and then press and fix the part 6 through the fixing component 2. At this time, press down the limit end cap 42 through the hydraulic equipment until the limit end cap 42 abuts against the washer 45, and complete the closing treatment of the fuel injection port 61.

[0039] It should be noted that when first extruding, the washer 45 with the largest thickness is used. When the flow rate and target shooting test are unqualified, replace the washer 45 with gradually decreasing thickness until the test is qualified. This avoids the problem of too small extrusion of the fuel injection port 61. The thickness gradient of each washer 45 is set according to different specifications of the fuel injection port 61 in combination with the analysis of the test results to ensure the closing effect of the closing tooling.

[0040] In a preferred embodiment, as Figure 2 and Figure 4 shown, the fixing component 2 includes a gland 21 and a first screw 22. A first through hole 23 is opened on the gland 21, and a first threaded hole 12 corresponding to the first through hole 23 is opened at the bottom of the positioning groove 11. The first screw 22 passes through the first through hole 23 and is threadedly connected with the first threaded hole 12.

[0041] In this embodiment, when fixing the part 6, first buckle the gland 21 on the top of the part 6, then pass the first screw 22 through the first through hole 23 on the gland 21 and screw it into the first threaded hole 12. Tighten the first screw 22 with a wrench to press and fix the part 6. The operation is convenient and the fixation is firm.

[0042] In a preferred embodiment, as Figure 2 and Figure 4 shown, the bracket 3 includes a column 32. The column 32 is positioned and fixed on one side of the base 1 through the mounting assembly 5. A support block 33 is fixedly arranged obliquely above the positioning groove 11 at the top of the column 32. The first pin hole 31 is arranged on the support block 33. The bracket 3 has high structural strength and good supporting effect, providing a basis for the extrusion and necking of the necking assembly 4.

[0043] In a preferred embodiment, as Figure 2 and Figure 4 shown, the mounting assembly 5 includes a second pin rod 51 and a second screw 52. An installation groove 13 is formed on one side of the base 1. The lower part of the column 32 is embedded in the installation groove 13. A second pin hole 14 is formed in the installation groove 13. Second threaded holes 15 are respectively formed on both sides of the second pin hole 14 in the installation groove 13. A third pin hole 34 is formed on the column 32 corresponding to the second pin hole 14, and a second through hole 35 is formed corresponding to the second threaded hole 15. The second pin rod 51 passes through the third pin hole 34 and is inserted into the second pin hole 14. The second through holes 35 are all penetrated by the second screws 52, and the second screws 52 are threadedly connected to the corresponding second threaded holes 15.

[0044] In this embodiment, the lower part of the column 32 is positioned and fixed in the installation groove 13 through the cooperation of the second pin rod 51 and the second screw 52, ensuring the position accuracy of the first pin hole 31 and guaranteeing that the necking assembly 4 accurately extrudes the oil injection port 61 to complete the necking process.

[0045] In a preferred embodiment, the base 1, the fixing assembly 2, the bracket 3 and the necking assembly 4 are all made of stainless steel materials, with high structural strength, not easy to deform, not easy to corrode and rust, and long service life.
