[0023] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0026] See also Figure 1 and Figure 2 A main oil pump simulation jig shown in a preferred embodiment of the present application includes a jig body 1 and a centering dummy shaft 2. A connecting oil passage 11 is provided in the jig body 1, an inlet flange 12 is provided at one end of the connecting oil passage 11, and an outlet flange 13 is provided at the other end of the connecting oil passage 11. An oil discharge port 14 connected to the connecting oil passage 11 is provided on the jig body 1. The centering dummy shaft 2 is rotatably provided on the side of the jig body 1, and is used to connect with the motor shaft magnetic seat for position alignment.
[0027] When assembling the main oil pump, the installation position of the inlet and outlet oil pipes needs to be determined according to the position of the inlet and outlet flanges 13 on the main oil pump. After the position is determined, the oil pipes are connected to the inlet and outlet flanges 13 on the main oil pump. However, if the main oil pump has not arrived, the installation position of the inlet and outlet oil pipes cannot be determined, and it is necessary to wait until the main oil pump arrives before the installation can be carried out, which delays the assembly time. At the same time, during the oil circulation cleaning experiment, impurities in the oil product can easily jam the main oil pump, causing quality risks.
[0028] Therefore, according to the scheme of the embodiment of the utility model, by setting the connecting oil passage 11 and the inlet flange 12 and the outlet flange 13 on the fixture body 1, the installation position of the inlet and outlet oil pipes can be determined in advance instead of the main oil pump, so as to avoid the main oil pump not arriving and delaying the assembly time; at the same time, the main oil pump can be replaced for oil circuit cleaning to avoid the impurities in the oil product from easily blocking the main oil pump and causing quality risks. It should be noted here that when the actual main oil pump is assembled, the installation position of the actual main oil pump needs to be adjusted according to the position of the motor. Specifically, the centering spindle on the side of the actual main oil pump is usually attached to the magnetic seat of the motor shaft for connection, and then the front, back, left and right positions of the actual main oil pump are adjusted in detail by the reading of the dial indicator. Therefore, in this embodiment, in order to realize the centering function, a centering dummy shaft 2 that can also rotate is set to connect with the motor shaft to adjust the position of the fixture body 1. After the position adjustment of the fixture body 1 is completed, the installation position of the inlet and outlet oil pipes is determined according to the position of the inlet and outlet flanges 13 on the fixture body 1.
[0029] The following is a detailed description with specific embodiments:
[0030] See also Figure 1 and Figure 2 , the installation and fixing position of the main oil pump simulation fixture is consistent with the installation and fixing position of the actual main oil pump. The setting position and size of the inlet flange 12, the outlet flange 13 and the centering dummy shaft 2 are consistent with the setting position and size of the inlet flange 12, the outlet flange 13 and the centering main shaft of the actual main oil pump. In order to ensure that the fixture body 1 can replace the actual main oil pump to complete the position determination of the inlet and outlet oil pipes, it is necessary to ensure that the installation and fixing position of the main oil pump simulation fixture, the inlet flange 12, the outlet flange 13 and the setting position and size of the centering dummy shaft 2 are consistent with the actual main oil pump, so as to accurately determine the installation position of the inlet and outlet oil pipes, so that they can be quickly installed after the main oil pump arrives.
[0031] See also Figure 1 and Figure 2 The main oil pump simulation jig also includes a fixed base 3, a connecting column 4 and a side fixing seat 5. The connecting column 4 is arranged between the jig body 1 and the fixed base 3. The side fixing seat 5 is arranged between the centering dummy shaft 2 and the jig body 1. Specifically, in this embodiment, the jig body 1, the connecting column 4 and the fixed base 3 are arranged in an I-shape from top to bottom, and the jig body 1 is arranged horizontally. The connecting oil channel 11 is a U-shaped structure. The inlet flange 12 and the outlet flange 13 are located on the upward side of the jig body 1.
[0032] See also Figure 1 and Figure 2The centering dummy shaft 2 is provided with an auxiliary rotating rod 21, and the fixed base 3 is provided with an adjustable ejector bolt (not shown in the figure). After the centering dummy shaft 2 is rotated and aligned with the motor shaft by the auxiliary rotating rod 21, the installation and fixing position of the main oil pump simulation jig is adjusted by adjusting the ejector bolt on the fixed base 3 or adding a gasket at the bottom thereof according to the reading of the dial indicator, thereby accurately simulating the installation and fixing position of the actual main oil pump.
[0033] See also Figure 1 , the oil drain port 14 is located at the lowest position of the connecting oil passage 11. When cleaning the oil circuit, the main oil pump simulation fixture of this embodiment can be used to replace the actual main oil pump, and the connecting oil passage 11 can be connected to the inlet and outlet oil pipes for oil circuit circulation cleaning experiments. In order to avoid the trouble of oil leakage after cleaning, the oil drain port 14 is designed at the lowest position of the corresponding connecting oil passage 11 on the fixture body 1, which can facilitate the discharge of the oil in the connecting oil passage 11. Drain the oil first and then dismantle it.
[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
