Description

Technical Field

[0001] This utility model relates to the field of oil pump assembly technology, and more specifically, to a tooling for simulating the flexibility of an oil pump rotor assembly. Background Technology

[0002] Key components of the oil pump include the pump body, cover plate, shafts, transmission gears, and connecting screws. After assembly, the rotational flexibility of the inner and outer rotors of the oil pump needs to be manually checked to ensure normal operation and prevent serious safety accidents such as engine cylinder burnout caused by the inflexible rotation of the oil pump leading to failure to supply oil. The specific operating steps are as follows: First, the operator manually pushes the pump body in the simulated fixture to the designated position; then, the rotor is placed in the rotor chamber of the fixture, and the entire device is pushed to the bottom of the cylinder; after starting the cylinder, the operator manually rotates the outer shaft at least a number of revolutions equal to the number of teeth to determine whether the rotation is smooth; after completing the test, the cylinder is started again to raise the pressure plate, and then the fixture is moved back to its original position; finally, the shaft assembly is manually lifted, and the rotor assembly is removed from the fixture and placed in the storage container.

[0003] The existing technology has the following problems: the inspection process for each product requires repeated manual actions, resulting in low efficiency. Typically, an operator can only complete the inspection of approximately 500 products in 8 hours. The judgment of rotational flexibility relies entirely on the operator's feel, which not only requires a high level of skill but is also easily affected by personal experience and condition. Prolonged manual operation leads to operator fatigue, thereby reducing the consistency and accuracy of the judgment results. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Example 1

[0029] This utility model embodiment provides a flexible simulation tooling for an oil pump rotor 400 assembly, which reduces manual operation, increases the accuracy of flexible simulation experiments, and improves efficiency.

[0030] Please see Figure 1 as well as Figure 2The oil pump rotor 400 assembly flexibility simulation tooling provided in this embodiment includes: an upper cover plate 100 with a first groove; a base 200 with a second groove matching the first groove of the upper cover plate 100, the two combined to form a closed rotor 400 receiving cavity; a rotating shaft 800 passing through the base 200 and the upper cover plate 100, and connected to the rotor 400; a drive gear 600 installed at one end of the rotating shaft 800 and located outside the base 200; a first drive unit driving the drive gear 600 to rotate along the axis; and a detection unit including a magnetic induction tachometer 700 for detecting the speed of the gear. In this embodiment, the upper cover plate 100 with the first groove and the base 200 with the second groove are matched to form a closed rotor 400 receiving cavity, ensuring that the rotor 400 can be tested in a stable environment. This design not only facilitates the installation and disassembly of the rotor 400, but also effectively prevents external factors from interfering with the test results. In this embodiment, the rotating shaft 800 transmits power to the rotor 400. In this embodiment, the magnetic induction tachometer 700 is used to monitor the rotational speed of the drive gear 600 in real time, which helps to directly evaluate the flexibility of the rotor 400. Since the rotational speed is closely related to the flexibility, the operator only needs to observe the data displayed by the tachometer to quickly determine whether the rotor 400 meets the standard, which simplifies the process of manual visual inspection and reduces labor intensity.

[0031] In this embodiment, the first drive unit includes one or more jet devices 900, which are angled relative to the gear to provide rotational driving force. In this embodiment, the drive gear 600 obtains rotational driving force through one or more angled jet devices 900. In this embodiment, the jet device 900 is provided with a nozzle.

[0032] In this embodiment, a bearing 300 is provided between the rotating shaft 800 and the base 200 to ensure smooth movement of the rotating shaft 800. The bearing 300 between the two reduces friction and improves test accuracy.

[0033] In this embodiment, a guide post 500 extending in the vertical direction is also included. The upper cover plate 100 and the base 200 are provided with guide holes corresponding to their positions. The guide post 500 is disposed in the guide hole, so that the upper cover plate 100 is stable and reliable when it moves up and down.

[0034] In this embodiment, a second driving unit is also included, which drives the upper cover plate 100 to reciprocate in the vertical direction.

[0035] In this embodiment, the second drive unit is a telescopic cylinder, which is a hydraulic cylinder.

[0036] The following is a detailed description of the usage process of the oil pump rotor 400 assembly flexibility simulation tooling in Embodiment 1 of this utility model:

[0037] In use, the rotor 400 is placed in the second groove, and the second drive unit drives the upper cover plate 100 to move down, fixing the rotor 400 in the rotor 400 receiving cavity. The airflow from the nozzle drives the drive gear 600 to rotate, and the magnetic induction speed sensor 700 automatically detects and displays the gear speed. The operator judges the flexibility of the rotor 400 based on the stability of the displayed speed. After the judgment is completed, the air source is turned off, the second drive unit is driven, and the upper cover plate 100 is driven to rise. The inspected product is manually removed, and then the product to be inspected is placed in; the operation cycle repeats.

[0038] Example 2

[0039] This utility model embodiment provides a flexible simulation tooling for an oil pump rotor 400 assembly, which reduces manual operation, increases the accuracy of flexible simulation experiments, and improves efficiency.

[0040] The oil pump rotor 400 assembly flexibility simulation tooling provided in Embodiment 2 of this utility model differs from Embodiment 1 only in that, in this embodiment, a vibration sensor for detecting the vibration level of the rotor 400 and a torque sensor for detecting the torque data of the rotor 400 are also included. The former is used to measure the vibration level of the rotor 400 during operation, while the latter records the torque data borne by the rotor 400, which is convenient for subsequent fault diagnosis, performance optimization and preventive maintenance.

[0041] The embodiments of this utility model have at least the following advantages:

[0042] This invention provides a tooling for simulating the flexibility of a disassembled oil pump rotor assembly, significantly improving the efficiency and accuracy of such simulations. A closed rotor housing is formed by the combination of a top cover and a base, facilitating rotor installation. An air jet device in the first drive unit drives the gears to rotate, which in turn drives the rotor. A magnetic induction tachometer accurately detects the gear speed. The flexibility of the oil pump rotor assembly is positively correlated with its rotational speed; the speed can be visually assessed by the tachometer to determine if the flexibility meets the standard. Airflow-driven pump rotation replaces manual gear rotation, effectively reducing operator workload. Furthermore, the inclusion of guide columns, vibration sensors, and torque sensors comprehensively detects rotor vibration levels and torque data, providing reliable data support for subsequent maintenance and optimization, thereby significantly improving the efficiency and accuracy of oil pump rotor assembly flexibility simulation.
