Description

Technical Field

[0001] The utility model relates to the technical field of oil pump processing, in particular to an oil pump cover stacking device. Background Art

[0002] As we all know, the oil pump cover is the top cover of the oil pump. It is connected to the pump casing to form a closed space for accommodating parts such as rotors and blades. Seals are usually installed inside the pump cover to prevent oil leakage.

[0003] Patent application number CN202223089693.5 discloses an oil pump cover stacking device, including a base, a first adjustment component and a handle. The base is horizontally arranged, and an electric cylinder is provided inside it. The piston rod of the electric cylinder passes through the base and is arranged horizontally upward. The first adjustment component is horizontally arranged at the end of the piston rod of the electric cylinder. Two second adjustment components are slidably provided on the first adjustment component. Each second adjustment component is provided with a limit component, and the handle is provided at the top of the limit component.

[0004] Although this device facilitates the stacking of oil pump covers, the oil pump cover itself is heavy. When the oil pump cover slides from the upper part to the lower part of the limit rod, it will generate a large impact force on the second slide and the first slide, which will cause certain damage to the second slide, the second hand wheel, the first slide and the first hand wheel. However, this device is not equipped with a device to buffer the impact force. Therefore, this device needs to be repaired after being used for a period of time. During the repair period, the device cannot be used normally, which reduces the work efficiency to a certain extent. Therefore, its practicality is not very good and there is room for improvement.
