[0071] The clamp device for an oil rail in this embodiment 1 employs a two-pin, one-plane positioning method for both the third oil rail 3 and the fourth oil rail 4, resulting in more accurate positioning and more stable clamping. Specifically, the first positioning pin 15-1 of the first positioning seat 15, the third positioning pin 17-1 of the third positioning seat 17, and the fifth positioning slope 19-1 of the fifth positioning seat 19 implement the two-pin, one-plane positioning method for the third oil rail 3.

If the fourth fuel rail 4 is installed in the reverse direction, the corresponding injector seat of the fourth fuel rail 4 will be blocked by the second anti-error block 28, and the fourth fuel rail 4 will not be able to achieve the two-pin and one-side positioning, thus reminding the operator that the installation is reversed.

[0073] The first fuel rail 1 and the second fuel rail 2 are arranged relative to each other (i.e., relative to each other in the left-right direction, and the first fuel rail 1 is in the same direction as the second fuel rail 2 after rotating 180° in the horizontal plane), which facilitates the use of the fifth positioning seat 19 to position the speed limit bracket of the first fuel rail 1 and the speed limit bracket of the second fuel rail 2, and simultaneously positions the first fuel rail 1 and the second fuel rail 2 in the circumferential direction. The third fuel rail 3 and the fourth fuel rail 4 are arranged in the same direction.

[0074] The third fixing seat 7 and the fourth fixing seat 8 on the right side of the base plate 10 simultaneously clamp the third oil rail 3 and the fourth oil rail 4, which facilitates the processing of the sensors on the two oil rails and the finishing of the front and rear ends (hereinafter referred to as the "second process").

[0075] The clamp device for the oil rail in the first embodiment is compact, highly versatile, simple to manufacture, and easy to maintain.

The four injector seats of the first fuel rail 1 and the second fuel rail 2 face upward, and the sensors of the third fuel rail 3 and the fourth fuel rail 4 face upward.

[0077] In the second embodiment, a clamp device for an oil rail includes both a fixing device for clamping two oil rails in a first process and a fixing device for clamping two oil rails in a second process. That is, the two oil rails in the first process and the two oil rails in the second process can be clamped simultaneously, making it convenient for the supporting equipment to perform the first process processing on the two oil rails in the first process and simultaneously convenient for the supporting equipment to perform the second process processing on the two oil rails in the second process. The clamp is more compact and more versatile.
