Abstract
The invention provides a working table for installing a mechanical seal of a water pump and relates to the technical field of water pump machining tools. The working table comprises a working table body, a supporting frame, a supporting arm, a mounting base, a sliding sleeve, a slide bar, a support, a hand wheel shaft, a hand wheel, an assembly port, a lifting rack, a gear, a baffle and a reset spring. The working table is characterized in that an annular pump cover base is arranged at the position, opposite to the slide bar, of the working table body, the lower end of the slide bar is provided with a sealing ring pressing plate, a buffer pressure pad is arranged on the sealing ring pressing plate, a vertical threaded rod is formed in the upper portion of the mounting base, a stroke adjusting bolt is arranged in the threaded hole, and the upper end of the slide bar is provided with a limiting stop dog matched with the stroke adjusting bolt. In the using process, a pump cover is placed on the pump cover base, a static ring of the mechanical seal is placed into a mounting groove of the pump cover, the stroke of the sealing ring pressing plate is adjusted, and then the hand wheel is rotated to drive the sealing ring pressing plate to press the static ring of the mechanical seal into the mounting groove of the pump cover. The working table has the advantages of being simple in structure, convenient to use, high in assembling accuracy, assembling speed and assembling quality, good in sealing performance and long in service life.
Description
technical field [0001] The invention relates to the technical field of water pump processing tooling, and specifically relates to a water pump mechanical seal installation workbench with simple structure, convenient use, high assembly precision and fast speed. Background technique [0002] We know that the water pump includes a pump body, a pump shaft, an impeller and a pump cover. A mechanical seal is provided between the pump cover and the impeller, and the static ring of the mechanical seal is installed on the inner side of the pump cover. In the existing water pump assembly process, workers manually press and assemble the static ring of the mechanical seal into the static ring installation groove on the pump cover. In this assembly method, the flatness of the static ring of the mechanical seal is poor after assembly, the assembly accuracy is low, deviation is easy to occur, and the assembly quality is poor, which reduces the sealing performance of the mechanical seal and...
