Abstract
The utility model discloses a high-pressure oil pump installation phase detection device assembly, which comprises a high-pressure oil pump, a cylinder cover for installing the high-pressure oil pump, a gear installed on the high-pressure oil pump and a phase detection tool, wherein the cylinder cover is provided with a cylinder cover check hole, and the gear is provided with a gear check hole; the phase detection tool comprises a long rod, a middle short rod and a head handle, wherein the length of the middle short rod is the depth of a gear inspection hole, and the total length of the long rod and the length of the middle short rod is the distance from a bolt mounting surface of the cylinder cover inspection hole to a high-pressure oil pump shaft. Whether the installation phase is correct can be checked when the internal structure cannot be seen after the installation, the structure is simple, the operation is convenient, and the detection efficiency is high.
Description
Technical Field
The utility model discloses the coaxial series connection transmission phase place of a plurality of annexs detects technical field, concretely relates to high-pressure oil pump installation phase place detection device assembly.
Background
The engine high-pressure oil pump is driven by an engine camshaft, and in order to prevent the load peak value superposition of the high-pressure oil pump and the camshaft, the high-pressure oil pump and the camshaft need to be subjected to peak staggering design, so that the high-pressure oil pump and the camshaft need to be installed according to a certain phase angle during initial installation. However, the internal structure of the high-pressure oil pump and the camshaft cannot be seen after the high-pressure oil pump and the camshaft are installed, so that whether the phase is correct after the high-pressure oil pump and the camshaft are installed cannot be visually judged.
Disclosure of Invention
The utility model aims at providing a can judge whether correct high-pressure oil pump installation phase place detection device assembly under the condition of seeing inside result exactly to the not enough of above-mentioned technique.
In order to achieve the above object, the high-pressure oil pump installation phase detection device assembly designed by the utility model comprises a high-pressure oil pump, a cylinder cover for installing the high-pressure oil pump, a gear installed on the high-pressure oil pump, and a phase detection tool, wherein the cylinder cover is provided with a cylinder cover check hole, and the gear is provided with a gear check hole; the phase detection tool comprises a long rod, a middle short rod and a head handle, wherein the length of the middle short rod is the depth of a gear inspection hole, and the total length of the long rod and the length of the middle short rod is the distance from a bolt mounting surface of the cylinder cover inspection hole to a high-pressure oil pump shaft.
Further, the long rod and the middle short rod are coaxially arranged, the diameter of the long rod is the same as the inner diameter of the cylinder cover inspection hole, and the diameter of the middle short rod is slightly smaller than that of the long rod.
Further, the middle short rod is painted in red.
Compared with the prior art, the utility model has the advantages of it is following: the utility model discloses whether high-pressure oil pump installation phase place detection device assembly can inspect the installation phase place correctly when can't see inner structure after the installation, simple structure, convenient operation, and detection efficiency is high.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments.
The utility model discloses high-pressure oil pump installation phase detection device assembly, including high-pressure oil pump, be used for installing high-pressure oil pump's cylinder cap 1, install gear 3 and phase detection instrument 6 on high-pressure oil pump, seted up cylinder cap inspection hole 2 on the cylinder cap 1, seted up gear inspection hole 4 on the gear 3, as shown in fig. 1, 2.
Phase place measuring tool 6 includes stock 7, middle quarter butt 8 and head handle 5, and stock 7 and the coaxial arrangement of middle quarter butt 8, and the length of middle quarter butt 8 is the degree of depth of gear inspection hole 4, and the total length of stock 8 length and middle quarter butt 8 length is the distance of 2 bolt mounting faces of cylinder cap inspection hole to high-pressure oil pump axle, and the diameter of stock is the same with the internal diameter of cylinder cap inspection hole, and the diameter of middle quarter butt slightly is less than the diameter of stock. In addition, the middle short rod is colored in a color such as red for striking.
When the high-pressure oil pump is installed, if the phase assembly between the high-pressure oil pump and the engine is correct, the phase detection tool is inserted into the phase inspection hole, at the moment, the long rod of the phase detection tool extends into the gear inspection hole, the middle short rod is completely inserted into the cylinder cover inspection hole, namely, the surface of the head handle combined with the middle short rod is attached to the bolt installation surface of the cylinder cover inspection hole, as shown in fig. 4. If the high-pressure oil pump is installed incorrectly, the middle short rod is exposed outside the cylinder cover inspection hole completely, namely the surface of the middle short rod combined with the long rod is superposed with the bolt installation surface of the cylinder cover inspection hole, as shown in fig. 5, the long rod is not inserted into the gear inspection hole, which means that the high-pressure oil pump is installed again after being disassembled.
The utility model discloses whether high-pressure oil pump installation phase place detection device assembly can inspect the installation phase place correctly when can't see inner structure after the installation, simple structure, convenient operation, and detection efficiency is high.
