[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0022] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
[0023] This embodiment mainly describes the engine gear pump oil flow detection device, which is as follows:
[0024] like Figures 1 to 3As shown, the engine gear pump oil flow detection device includes a workbench 1 and a detection component 4. The workbench 1 is mainly used to support the engine 2, the gear pump 3 and the detection component 4. The detection component 4 is arranged on the workbench 1, and is used to detect whether the engine 2 is in good condition and whether the gear pump 3 will leak oil. The gear pump 3 is arranged at the output end of the engine 2 and is driven by the engine 2. The oil inlet end of the gear pump 3 is connected to the hydraulic oil tank 7 through the oil inlet pipe 71, and the oil outlet end of the gear pump 3 is connected to the detection component 4 through the oil outlet pipe 72. The detection component 4 is provided with an oil return pipe 73 connected to the hydraulic oil tank 7. The workbench 1 is provided with a fixing assembly 5 for quickly fixing the engine 2. The fixing assembly 5 includes a first fixing block 51, a second fixing block 52, and a movable clamping assembly 53 fixed to the workbench 1 by screws. The first fixing block 51 and the movable clamping assembly 53 are respectively perpendicular to and located on either side of the second fixing block 52. The movable clamping assembly 53, the first fixing block 51, and the second fixing block 52 form a mounting area 6 with an opening 61 on one side. When testing the engine 2 and the gear pump 3, the engine 2 is placed into the mounting area 6 through the opening 61 and abutted against the first fixing block 51 and the second fixing block 52. The movable clamping assembly 53 is adjusted toward the engine 2 to clamp the engine 2 on three sides. The engine 2 is a gasoline engine connected to a gasoline tank 8 via a gasoline pipe. When disassembling the engine 2, the movable clamping assembly 53 is adjusted away from the engine 2 and the engine 2 is removed from the opening 61. When replacing the engine 2 to be tested, the engine 2 can be quickly disassembled or fixed. The operation is simple and convenient, greatly improving work efficiency.
[0025] Specifically, the movable clamping assembly 53 includes a fixing sleeve 531, a threaded rod 532 and a pressure block 534. The fixing sleeve 531 is fixed on the workbench 1. A threaded hole that cooperates with the threaded rod 532 is provided on the fixing sleeve 531. The threaded rod 532 passes through the threaded hole of the fixing sleeve 531 and is threadedly connected to the fixing sleeve 531. The pressure block 534 is rotatably connected to the end of the threaded rod 532 close to the installation area 6. By rotating the threaded rod 532, the threaded rod 532 drives the pressure block 534 to move forward to press the engine 2 or move backward away from the engine 2. The fixing sleeve 531 mainly plays a fixing role, providing the pressure block 534 with a clamping force on the engine 2. In order to prevent the pressing block 534 from rotating with the threaded rod 532 during the rotation of the threaded rod 532, a guide groove 11 is provided on the workbench 1, and a slider (not shown in the figure) is provided at the bottom of the pressing block 534, which can extend into the guide groove 11 and slide in the guide groove 11. When the threaded rod 532 rotates, the slider (not shown in the figure) slides in the guide groove 11, and the guide groove 11 also limits the rotational deviation of the pressing block 534.
[0026] Specifically, there are two fixing sleeves 531 . The arrangement of the two fixing sleeves 531 can provide a lasting pressing force for the pressing block 534 and improve the stability of the pressing block 534 . The fixing sleeves 531 are fixing nuts.
[0027] Specifically, a rotating handle 533 is fixedly connected to the side of the threaded rod 532 away from the installation area 6. The setting of the rotating handle 533 makes it more convenient and labor-saving to rotate the threaded rod 532.
[0028] Specifically, the first fixing block 51, the second fixing block 52 and the pressing block 534 are all provided with an upward inclined surface on the side close to the engine 2, and the bottom of the engine 2 has a base 21 that rests against the inclined surface. In order to avoid wear between the edges of the inclined surface and the base 21 when tightening, the base 21 and the inclined surface rest on a rounded surface 22. The first fixing block 51, the second fixing block 52 and the pressing block 534 are provided with an upward inclined surface, which can fix and press the base 21 of the engine 2 in the horizontal and vertical directions, thereby improving the stability of the engine 2 and avoiding displacement due to vibration generated when the engine 2 is working, which affects the user experience.
[0029] Specifically, the detection component 4 includes a control valve 41 and a pressure gauge 42 provided on the control valve 41 for detecting the hydraulic oil pressure. The control valve 41 is provided with an operating handle, and the control valve 41 is opened or closed by the operating handle. When the control valve 41 is opened, the pressurized hydraulic oil passes through the control valve 41 and the pressure gauge 42 to display the pressure value of the hydraulic oil. According to the pressure value, it can be judged whether the quality of the gear pump 3 meets the standard. The pressure is tested for a period of time by operating the handle to observe whether the engine 2 has abnormal noise and other quality problems, and whether the gear pump 3 has oil leakage or other quality problems.
[0030] Specifically, the workbench 1 is fixed on a support frame 9 , rollers 91 are provided on the four corners of the support frame 9 , and a push handle 92 is provided on one side of the support frame 9 , and the workbench 1 can be moved by pushing the push handle 92 .

Therefore, they should not be understood as limitations on the present invention.
[0032] The above is a detailed introduction to the engine gear pump oil flow detection device provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified. These improvements and modifications also fall within the scope of protection of the claims of the utility model.
