[0040] The present embodiment is described in detail below with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 2As shown, this embodiment provides an electronic oil pump test tool, including: a collecting piece, having a collecting cavity, before the test operation, the collecting cavity is used to store oil, or, after the test operation, the collecting cavity is used to collect oil, an interface is provided on the collecting cavity, and the interface is used for the circulation of oil; a heating piece and a filtering piece, which are arranged in the collecting piece, the heating piece is used to heat the oil in the collecting cavity, the filtering piece is connected to the interface, and is used to filter the oil flowing from the interface to the electronic oil pump 8 after heating; a detection piece, which is arranged on the collecting piece, and the detection piece is connected with Valve, the valve is a throttle valve 17; control component 11, the control component 11 is also installed on the collecting component, and is electrically connected to the electronic oil pump 8, the throttle valve 17, the heating component, the filter component, and the detection component, the throttle valve 17 is used to preset the operating pressure, and the detection component is used to detect the speed, oil flow and oil pressure value of the electronic oil pump 8 under the preset operating pressure; cooling component 12 and electromagnetic interference component 18, the cooling component 12 and the electromagnetic interference component 18 are both installed on the collecting component, the cooling component 12 is used to cool the electronic oil pump 8, and the electromagnetic interference component 18 is used to perform electromagnetic interference on the electronic oil pump 8. The electronic oil pump 8 is fixedly connected to the collecting member through the fixing hole 1, and the interface includes an oil inlet 2 and an oil outlet 3. The oil inlet 2 is connected to the oil inlet of the electronic oil pump 8, and the oil outlet 3 is connected to the oil outlet of the electronic oil pump 8. After the above-mentioned components are connected, a proper amount of oil is added to the collecting member, and the content of the oil needs to be able to submerge the filter element. After the oil is added, the oil is heated by the heating member, and the heated oil is sucked into the electronic oil pump 8 through the oil inlet 2, and the oil in the electronic oil pump 8 is discharged through the oil outlet 3. Finally, the discharged oil flows into the collecting cavity in the collecting member through the oil pipe 14 for storage; in the process of conducting the test, firstly, the oil in the collecting cavity needs to be heated to the temperature standard required for the test by the heating member, and secondly, the throttle valve 17 is controlled by the control member 11 to adjust the test pressure while starting the electronic oil pump 8. After the speed of the electronic oil pump 8, the oil flow data change and the oil pressure value detected by the test member are stable, the various test values ​​can be recorded. The test fixture integrates the heating element, filtering element, valve and detection element on the collecting element, so that one fixture can complete multiple test operations in sequence, solving the problem of large space occupied by the traditional electronic oil pump 8 test that requires connecting multiple fixtures through pipelines; at the same time, the collecting element has a collecting cavity, which can store and recycle the oil, and there is no need to connect the oil tank through pipelines. The filter element can filter the oil and recycle the oil, reducing the investment in testing costs.

[0042] In the present embodiment, the collecting member is designed as a rectangular structure with a length of 250 mm, a width of 200 mm, and a height of 300 mm, which can be flexibly moved according to changes in the test scene; the interface also includes a pressure measuring port 4, an oil filter interface 5, and a flow interface 6, which are all arranged on the side wall of the collecting member and connected to the collecting cavity, and the filter is connected to the oil filter interface 5; the detection member includes a flow detection member and a pressure detection member, the throttle valve 17 is connected to the flow detection member, the flow detection member is connected to the flow interface 6, and the pressure detection member is connected to the pressure measuring port 4. Further, the collecting member is an oil collecting box 7, which has an opening at the top of the oil collecting box 7, the opening is connected to the collecting cavity, and the opening is used for adding oil. In the present embodiment, the flow detection member is a flow meter 15, the pressure detection member includes a pressure sensor 16 and a pressure gauge, the heating member is a heater 9, and the filter is a filter 10. The selection of the above components is a preferred example and is not limited here.

[0043] In this embodiment, the tooling also includes a cooling component 12 and an electromagnetic interference component 18 , both of which are installed on the collecting component. The cooling component 12 is used to cool the electronic oil pump 8 , and the electromagnetic interference component 18 is used to perform electromagnetic interference on the electronic oil pump 8 .

[0044] In order to better understand this tooling, the following is a description of each test as an example:

[0045] When the electronic oil pump 8 is tested for performance, Figure 4 As shown, firstly, the oil in the collecting cavity of the oil collecting box 7 needs to be heated to the temperature standard required for the test through the heater 9. The heated oil is filtered by the filter 10 and then transported to the electronic oil pump 8. Secondly, the electronic oil pump 8 is connected to the voltage-stabilized DC power supply 13. The control component 11 controls the throttle valve 17 to adjust the test pressure while starting the electronic oil pump 8. After the reading of the pressure sensor 16 stabilizes, the speed of the electronic oil pump 8 is recorded, the flow meter 15 records the change in the oil flow data, and the pressure gauge records the oil pressure value. Finally, the oil flows into the oil collecting box 7 through the oil pipe 14. The purpose of the fatigue test of the electronic oil pump 8 is to examine whether the performance of the electronic oil pump 8 will be abnormal under long-term load conditions. On the basis of the performance test of the electronic oil pump 8, as shown in FIG. Figure 5As shown, after the communication of the electronic oil pump 8 is lost, it will continue to maintain the original rotation speed, so that the fatigue test of the electronic oil pump 8 does not require the control component 11, the flow meter 15 and the heater 9. Under normal temperature conditions, the fatigue test time usually takes hundreds or even tens of thousands of hours. Due to the long test time, the impurities in the oil will increase, and the filter 10 can be used to deal with the impurities very well, which greatly saves resources; during the test, after determining the opening of the throttle valve 17, the control component 11, the flow meter 15 and the heater 9 are removed from the oil collecting box 7, and the cooling component 12 is installed. The electronic oil pump 8 will continue to generate heat during rotation, and the cooling component 12 can cool the electronic oil pump 8. After the test is completed, the performance changes of the electronic oil pump 8 are monitored. Furthermore, the cooling component 12 is preferably an electric fan. Using an electric fan for cooling can reduce the test cost. The purpose of the EMC test of the electronic oil pump 8 is to examine whether the electronic oil pump 8 can still maintain the original speed under electromagnetic interference. Since the number of EMC tests of the electronic oil pump 8 is small, the filter 10, the flow meter 15, the pressure sensor 16 and the throttle valve 17 can be removed on the basis of the performance test of the electronic oil pump 8, and the electromagnetic interference component 18 can be installed on the oil collecting box 7. Figure 6 As shown, during the test, different speed instructions are sent to the electronic oil pump 8 through the control component 11, and various types of electromagnetic interference components 18 are used to monitor the difference between the target speed and the actual speed of the electronic oil pump 8. The purpose of the low-temperature start test of the electronic oil pump 8 is to examine whether the electronic oil pump 8 can start normally under extremely cold spontaneous combustion conditions. On the basis of the EMC test of the electronic oil pump 8, the electromagnetic interference components 18 are removed, such as Figure 7 As shown, the entire electronic oil pump 8 test tooling is placed in the low-temperature chamber 19, and a lower speed is sent through the control component 11 to compare the difference between the actual speed of the electronic oil pump 8 and the target speed. If the difference between the actual speed and the target speed is small, the low-temperature starting performance of the electronic oil pump 8 is good, otherwise it does not meet the low-temperature starting requirements. It is worth noting that in the above various test processes, the control component 11 is preferably a host computer.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
