[0002] Electronic oil pump refers to the oil pump that can realize fuel supply by electronic control. It adopts high-precision electronic control components and advanced oil supply system, with the characteristics of high efficiency, accuracy and low consumption. The working principle of electronic oil pump is mainly based on real-time monitoring of sensors, accurate calculation of electronic control system and accurate adjustment of fuel injection. Specifically, the sensor detects the working state and demand of the engine, such as speed, throttle position, air flow, etc., and transmits these parameters to the electronic control system. The electronic control system calculates and adjusts the fuel supply according to the data provided by the sensor and the preset program, and finally sprays the fuel into the engine combustion chamber at high speed through the high-pressure oil nozzle.

[0003] Electronic oil pump needs to be tested for performance to ensure that the electronic oil pump can work normally. During testing, various detection sensors are used to collect data, and then the performance indicators of the electronic oil pump are analyzed and judged according to the collected data. However, when the existing electronic oil pump is tested for sealing, if the electronic oil pump has sealing problems, oil leakage may occur. The existing test bench generally only installs fixtures for positioning the electronic oil pump, and lacks processing of oil leakage on the bench surface. Once the test bench accumulates oil, it will obviously affect the assembly. UTILITY MODEL CONTENT

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model is an electronic oil pump performance data acquisition and testing device, including a test bench 1. A test module 2 is installed on the test bench 1. The test module 2 uses existing technology; it only needs to be able to perform performance testing on the electronic oil pump. Data acquisition during testing also utilizes various existing sensors and testing instruments, all contained within the test module 2. Since this is readily available technology in this industry, it will not be elaborated upon further. A rectangular slot 3 is provided on the test bench 1, and a test fixture 4 is inserted into the rectangular slot 3. An oil outlet hole 5 communicating with the outside is provided at the bottom of the rectangular slot 3. An automatic oil removal mechanism 6 is provided on the test bench 1. The automatic oil removal mechanism 6 includes:

[0026] An electric telescopic rod 61 is installed at its bottom on one side of the test bench 1. The end of the electric telescopic rod 61 is detachably and fixedly connected to the degreasing plate 62. The bottom of the degreasing plate 62 is also provided with a telescopic component 63. The bottom of the telescopic component 63 is provided with a bonding plate 64. The bottom surface of the bonding plate 64 is in close contact with the upper surface of the test bench 1.

[0027] In this embodiment, by setting up an automatic oil removal mechanism 6, if oil leakage occurs during the testing of the electronic oil pump, the automatic oil removal mechanism 6 will remove the oil on the test bench 1 after the electronic oil pump test is completed and before the new electronic oil pump is inserted into the rectangular slot 3 through the test fixture 4. This prevents the leaked oil from affecting the testing process and avoids the problem of stubborn oil stains forming due to untimely cleaning. Specifically, the electric telescopic rod 61 extends when cleaning is needed, driving the connected oil removal plate 62 and the bonding plate 64 to move. Under the action of the telescopic component 63, the bottom of the bonding plate 64 is kept in close contact with the upper surface of the test bench 1, thereby achieving the purpose of concentrating the oil to one side. A collection tank can be set on the corresponding side to achieve centralized collection of oil. At the same time, some oil will enter the rectangular slot 3 when passing through it and then leak out from the oil outlet 5, thereby achieving the purpose of effective oil cleaning.

[0028] The telescopic component 63 includes a lower groove 631 and an upper protrusion 632. The lower groove 631 is formed on the bottom surface of the degreasing plate 62, and the upper protrusion 632 is disposed on the top surface of the bonding plate 64. The lower groove 631 and the upper protrusion 632 cooperate with each other. A spiral groove 633 penetrating through the degreasing plate 62 is formed on the top surface of the lower groove 631. A T-shaped screw 634 is spirally connected in the spiral groove 633. The bottom of the screw 634 contacts the upper protrusion 632. A spring 635 is connected between the upper protrusion 632 and the bottom surface of the lower groove 631. Two springs 635 are provided. The spiral groove 633 and the T-shaped screw 634 are located in the middle of the lower groove 631, and the two springs 635 are symmetrically distributed on both sides of the T-shaped screw 634. The bottom thickness of the bonding plate 64 is less than the thickness of the middle and upper parts, and a sleeve 636 is fixedly provided at the bottom of the bonding plate 64. The sleeve 636 is made of silicone material. The cross-section of the lower groove 631 and the upper protrusion 632 is both set as a rectangular structure.

[0029] In this embodiment, a specific implementation of the telescopic component 63 is given. In use, by rotating the screw 634 in both directions, the screw 634 is spiraled up and down in the spiral groove 633 to change the depth of the upper protrusion in the lower groove 631, thereby adaptively adjusting the fit between the bottom surface of the bonding plate 64 and the upper surface of the test platform 1, thus achieving the best oil removal effect; and under the elastic reset action of the spring 635, when the screw 634 moves upward, the bonding plate 64 can quickly move upward and reset.

[0030] The silicone sleeve 636 reduces wear on the bottom of the bonding plate 64. Simply replacing the sleeve 636 is all that's needed, making it quick and easy.

[0031] A movable baffle 637 is provided at the opening of the lower groove 631, and the diameter of the connection between the upper protrusion 632 and the bonding plate 64 is smaller than the top diameter of the upper protrusion 632. The movable baffle 637 can prevent the upper protrusion 632 from detaching from the lower groove 631, thus preventing the bonding plate 64 from effectively performing the cleaning action.

[0032] The bottom surface of the degreasing plate 62 has two dovetail grooves 638, each containing a movable baffle 637 that is slidably connected to it. The length of each movable baffle 637 is greater than the length of the corresponding dovetail groove 638. The dovetail grooves 638 effectively cooperate with the movable baffles 637, allowing the movable baffles 637 to move freely and selectively prevent the upper protrusion 632 from disengaging from the lower groove 631. Simultaneously, the movable baffles 637 are restricted from vertical disengagement from the dovetail grooves 638, allowing only horizontal sliding, thus ensuring efficient operation of the movable baffles 637.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
