The invention discloses a vacuum pump with a novel assembly structure and an assembly method of the vacuum pump and relates to the technical field of vacuum pumps. The vacuum pump comprises an upper end cover, a pump chamber, a pump core and a lower end cover; and pump chamber regulation holes and lower end cover regulation holes are arranged by matching with positioning devices in three directions and a positioning ruler. The vacuum pump with the novel assembly structure and the assembly method of the vacuum pump, by arranging regulation holes, in the assembly process of the vacuum pump, positioning mounting of the pump chamber and the lower end cover can be performed firstly, and determination of a fixed interval between the side wall of the pump chamber and the pump core is realized bymatching with an assembly device, so that the purposes that the vacuum pump is liable to mount and good in mounting effect, and a mounting interval is ensured are achieved; by arranging positioning sheets, in the mounting process of the vacuum pump, an interval distance between the side wall of the pump chamber and the pump core can be rapidly and accurately determined, and the purposes of novel assembly structure and good assembly effect of the vacuum pump are achieved.
Description
technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to an assembly method of a vacuum pump with a novel assembly structure. Background technique [0002] Due to the rapid advancement of automobile driving methods, more and more automobiles rely on external vacuum sources to provide booster vacuum during braking, so electric vacuum pumps for automobiles are more and more widely used. However, in the manufacture of existing vacuum pumps, since the pump core of the vacuum pump is set eccentrically in the pump chamber, and the gap between the pump core and the side wall of the pump chamber needs to be controlled within a certain range, in the actual installation process, it is impossible to guarantee the distance between the pump core and the side wall of the pump chamber. The clearance of the vacuum pump greatly reduces the actual use effect of the vacuum pump. [0003] For example, the Chinese invention CN106481556A discloses a v...
