Description

Technical Field

[0001] The utility model relates to the technical field of oil-free performance detection devices, in particular to an oil-free performance testing device for an oil pump. Background Art

[0002] The motorcycle oil pump performance testing process is a crucial link in the motorcycle oil pump production process. It is directly related to whether the finished oil pump can meet the lubrication needs of the engine and its long-term operating reliability.

[0003] Traditional oil pump performance testing typically uses a pump oil test to assess key parameters such as efficiency, pressure output, and flow rate. While this method can accurately reflect the actual operating status of the oil pump, it has significant drawbacks, including long testing time, high testing costs, and environmental pollution. Traditional pump oil testing requires preheating the oil to operating temperature, which is time-consuming and must be repeated before each test, resulting in inefficiencies across the entire production line. Pump oil testing also requires large amounts of lubricant, which often cannot be reused after a test and must be disposed of as waste, increasing material costs. Furthermore, the energy required to produce the oil represents a significant expense. Waste oil generated after testing requires specialized disposal, and improper handling can potentially pollute the environment. Furthermore, frequent exposure to oil and fat can also have adverse effects on human health. Utility Model Content

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0035] Example 1

[0036] The embodiment of the present utility model provides an oil-free performance test device for an oil pump 700 to replace the oil pump test in the prior art.

[0037] See also Figures 1 to 4 The present invention provides an oil-free performance test device for an oil pump 700, comprising: a support unit, comprising a vertically arranged support base 110 and a vertical plate 120, wherein the support base 110 is provided with a positioning hole for positioning the oil pump 700 during installation, so as to determine the installation position of the oil pump 700; a pressing base 200, slidably connected to the vertical plate 120; a rotating unit, comprising a first rotating rod 520 and a fixed rod 510 provided on the pressing base 200, wherein the first rotating rod 520 is provided with a clamping portion for clamping the end of the oil pump shaft of the oil pump 700; a first driving unit 300, which drives the pressing base 200 to rotate. The base 200 moves back and forth along the extension direction of the vertical plate 120 to adjust the distance between the pressing base 200 and the support base 110, thereby ensuring that the first rotating rod 520 is stably clamped on the oil pump shaft of the oil pump 700 to ensure the implementation of the rotation operation; the second driving unit 400 drives the first rotating rod 520 to rotate around its axis to drive the oil pump 700 to rotate along the oil pump shaft; the monitoring control unit 600 includes a flow meter for monitoring the air flow of the oil pump 700 and a central processing unit electrically connected thereto. In this embodiment, the central processing unit is a single-chip microcomputer, and in this embodiment, the clamping part is a clamping claw.

[0038] In this embodiment, there are two flow meters, which are located corresponding to the oil inlet and oil outlet of the oil pump 700, so as to monitor the air flow of the oil inlet and oil outlet of the oil pump 700, and then monitor the performance of the oil pump 700 to achieve oil-free performance detection.

[0039] In this embodiment, there are two fixing rods 510, and their positions correspond to the oil inlet and oil outlet of the oil pump 700 respectively. The flowmeter is installed on the fixing rod 510. The fixing rod 510 is provided with a first abutting portion. When the first driving unit 300 drives the clamping base 200 to descend, the abutting portion abuts against the top of the oil inlet / outlet of the oil pump 700. During the operation of the oil pump shaft of the oil pump 700, the oil inlet of the oil pump 700 forms a negative pressure, and the air is sucked into the inside of the oil pump 700 from the oil inlet of the oil pump 700; the oil outlet forms a positive pressure, and the air sucked into the inside of the oil pump 700 is discharged from the oil outlet of the oil pump 700.

[0040] In this embodiment, the central processing unit processes the air flow detected by the flow meter and completes the judgment on whether the performance of the oil pump 700 is qualified. The central processing unit is electrically connected to the indicator light and the alarm. The indicator light includes a qualified indicator light and an unqualified indicator light with inconsistent luminous colors. If the central processing unit detects that the air flow is qualified, the qualified indicator light of the detection equipment will light up; if the air flow is detected and determined to be unqualified, the unqualified indicator light of the detection equipment will light up and an alarm will be issued.

[0041] In this embodiment, the vertical plate 120 is provided with a sliding portion extending in the vertical direction, and the pressing base 200 is provided with a sliding groove extending in the vertical direction. The sliding groove is slidably connected to the sliding portion so that the pressing base 200 can reciprocate in the vertical direction.

[0042] In this embodiment, the first driving unit 300 is a telescopic cylinder detachably connected to the support base 110 , and a fixed end of the telescopic cylinder is fixedly connected to the pressing base 200 .

[0043] In this embodiment, the second driving unit 400 is a driving motor, and the driving motor is connected to the first rotating rod 520 via a motor shaft.

[0044] The following is a detailed description of the use of the oil pump 700 oil-free performance test device of Example 1 of the present utility model:

[0045] During use, the oil pump 700 to be tested is placed on the support base 110, and the position is positioned through the positioning hole of the support base 110 to ensure that the oil pump 700 is fixed in place. The device is started to drive the clamping base 200 to drive the rotating unit to move from top to bottom, clamping the oil pump 700 to be tested. The clamping part of the first rotating rod 520 is clamped on the oil pump shaft, and the second driving unit 400 drives the first rotating rod 520 to rotate, driving the oil pump 700 shaft to rotate; during the operation of the oil pump 700, the oil inlet hole of the oil pump 700 forms a negative pressure, and the air is sucked into the inside of the oil pump 700 from the oil inlet of the oil pump 700; the oil outlet forms a positive pressure, and the air sucked into the inside of the oil pump 700 is discharged from the oil outlet of the oil pump 700.

[0046] The central processing unit processes the air flow rate detected by the flow meter and completes the judgment on whether the performance of the oil pump 700 is qualified. The central processing unit is electrically connected to the indicator light and the alarm. The indicator light includes a qualified indicator light and a failed indicator light with inconsistent lighting colors. If the central processing unit detects that the air flow rate is qualified, the qualified indicator light of the detection equipment will light up; if the air flow rate is unqualified, the failed indicator light of the detection equipment will light up and an alarm will be issued.

[0047] After completing the above inspection, the second driving unit 400 drives the pressing base 200 to lift up, and the inspected oil pump 700 is taken out.
