Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rotor installation tooling technology, and in particular relates to a shaft oiling tooling. Background Technology
[0002] The rotor in the water pump is energized and rotates at high speed. Therefore, the amount of oil applied to the end of the rotor shaft determines whether the water pump can operate normally and efficiently.
[0003] Currently, rotor shaft oiling is done using positioning fixtures. Different positioning fixtures are used for rotor shafts of different diameters and lengths. Employees place the rotor shaft on the positioning fixture and manually rotate it. Lubricating oil is then poured onto the rotor shaft through an oil supply device. During the rotation of the rotor shaft, the areas to be oiled at both ends of the rotor shaft are coated with lubricating oil.
[0004] The existing positioning fixture has the following problems: it cannot store lubricating oil. When the oil supply equipment pours lubricating oil onto the rotor shaft, the lubricating oil that has been applied to the rotor shaft will fall off during the rotation process. As a result, the oiling of the part of the rotor shaft to be oiled is uneven, which in turn causes the rotor shaft to jam during operation after assembly, affecting the operation of the pump body.
[0005] Furthermore, the same positioning fixture cannot be used for rotor shafts of different lengths, requiring the design of multiple positioning fixtures, which increases production costs. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shaft oiling fixture that can uniformly apply lubricating oil to the areas to be oiled at both ends of the shaft.
