[0002] During the manufacturing process of the natural gas high-pressure common rail, it needs to be semi-finished using a milling machine. Semi-finishing operations include but are not limited to: pre-drilling and positioning holes on the natural gas high-pressure common rail milling machine, as well as milling and cutting the original holes of the natural gas high-pressure common rail milling machine to release deformation. During the semi-finishing process, the natural gas high-pressure common rail needs to be placed on a fixture and fixed by the fixture. However, there are reasonable errors in the dimensions of the manufactured natural gas high-pressure common rail, and the fixture currently used to fix the natural gas high-pressure common rail is a fixed fixture that is not movable. This will result in errors in the dimensions of the natural gas high-pressure common rail, which will then be unable to be clamped by the fixed fixture, or errors in the natural gas high-pressure common rail, which will then lead to the problem of the movable natural gas high-pressure common rail being damaged. Utility Model Content

[0035] The movable splint 5 is provided on the other side of the support base 2. The side of the movable splint 5 facing the support base 2 is provided with at least one contoured fixed support groove 6. The support base 2, the contoured movable support groove 4, and the contoured fixed support groove 6 match the shape of the natural gas high-pressure common rail 18.

[0036] The oil cylinder 7 is fixed on the base 1 , and the telescopic shaft of the oil cylinder 7 is connected to the movable splint 5 , and drives the movable splint 5 to move back and forth in a direction close to or away from the fixed splint 3 .

[0037] In this embodiment, a slot 8 is provided on the side of the fixed splint 3 that faces the support base 2. A longitudinal rotation axis 9 is disposed within the slot 8. The outer side of the contoured movable support slot 4 is rotatably connected to the slot 8 via the rotation axis 9. A first gap 10 is provided between the ends of the contoured movable support slot 4 and the slot 8. In this embodiment, the first gap 10 ranges from 1 to 10 mm. Two first springs are disposed between the bottom of the slot 8 and the sidewalls of the contoured movable support slot 4. The two first springs are located on either side of the rotation axis 9 and provide a cushioning effect on the ends of the rotating contoured movable support slot 4.

[0038] Multiple support bases 2 are provided, and the multiple support bases 2 are arranged in a row at intervals. The support bases 2 are rotatably provided on the base 1, and the support bases 2 can rotate in a vertical plane perpendicular to the horizontal plane. Similarly, the support bases 2 are arranged to be rotatable, rather than directly fixed to the base 1, to avoid the possibility that the natural gas high-pressure common rail 18 may not be able to fit tightly into the support base 2 due to errors, resulting in the natural gas high-pressure common rail 18 being higher than the contoured movable support groove 4 and the contoured fixed support groove 6.

[0039] Horizontal limit slots 11 are provided on both sides of the support base 2. A limit block 12 is fixed on both sides of each support base 2. The limit blocks 12 are located within the horizontal limit slots 11, with a second gap 13 between the upper and lower end surfaces of the horizontal limit blocks 12 and the horizontal limit slots 11. The combination of the horizontal limit slots 11 and the limit blocks 12 provides a limit for the rotation of the support base 2. The second gap 13 ranges from 1 to 5 mm.

[0040] In this embodiment, the base 1 is provided with grooves 14 corresponding in number to the number of support bases 2. A connecting post 15 is integrally formed at the bottom of the support base 2. The connecting post 15 is rotatably disposed within the groove 14.

The two second springs provide a cushioning effect on both ends of the support base 2 during rotation.

[0041] The base 1 is provided with a plurality of hollows 16. When the base 1 is turned over, the processing head of the milling machine can pass through the hollows 16 to perform semi-finishing processing on the natural gas high-pressure common rail 18.

[0042] The working principle of this embodiment is:

[0043] When the natural gas high-pressure common rail 18 is put into the fixture, the oil cylinder 7 drives the movable splint 5 to move in the direction away from the fixed splint 3 in advance. At this time, the movable splint 5 and the fixed splint 3 are in an open state. The natural gas high-pressure common rail 18 is placed on the support seat 2 by a manipulator or manually. The two sides of the natural gas high-pressure common rail 18 are limited by the contoured movable support groove 4. At the same time, the contoured movable support groove 4 will be rotated and fine-tuned due to the error size of the side of the natural gas high-pressure common rail 18, and the support seat 2 will be rotated and fine-tuned due to the error size of the bottom of the natural gas high-pressure common rail 18. At this time, the natural gas high-pressure common rail 18 is not manually positioned; then the oil cylinder 7 drives the movable splint 5 to move in the direction close to the fixed splint 3, and the natural gas high-pressure common rail 18 is clamped and fixed in the contoured fixed support groove 6 and the contoured movable support groove 4. At this time, the natural gas high-pressure common rail 18 is completely clamped. The support seat 2 and the contoured movable support groove 4 of the present application can rotate, providing a fault tolerance space for the clamped natural gas high-pressure common rail 18, avoiding the problem that the natural gas high-pressure common rail 18 cannot be clamped by the movable splint 5 and the fixed splint 3 due to errors, or the movable splint 5 and the fixed splint 3 will damage the movable natural gas high-pressure common rail 18. The processing fixture has a certain degree of fault tolerance, which protects the natural gas high-pressure common rail 18.
