Fuel pump rotor shaft assembling device of heater for vehicle

Abstract

The invention provides a fuel pump rotor shaft assembling device of a heater for a vehicle. The device comprises a frame, an oil seal press mounting mechanism, a bearing indentation rotor shaft mechanism, a bearing indentation pump body mechanism and a bearing check ring indentation pump body mechanism, wherein the oil seal press mounting mechanism, the bearing indentation rotor shaft mechanism, the bearing indentation pump body mechanism and the bearing check ring indentation pump body mechanism are arranged on the frame; the oil seal press mounting mechanism comprises a pump body positioning seat, an oil seal indentation head and a moving mechanism; the bearing indentation rotor shaft mechanism comprises a connecting seat, a positioning seat, a bearing inner ring indentation head and a moving mechanism; the bearing indentation pump body mechanism is provided with a bearing outer ring indentation head instead of the oil seal indentation head compared with the oil seal press mounting mechanism; and the bearing check ring indentation pump body mechanism is provided with a spring check ring indentation head instead of the oil seal indentation head compared with the oil seal press mounting mechanism and is provided with an orientation positioning seat. According to the device, a fuel pump rotor shaft and a pump body are assembled through the four sets of mechanisms; the device is convenient to use; and the assembly quality is ensured, and the assembly efficiency is improved.

Description

technical field [0001] The invention relates to a device for assembling a fuel pump rotor shaft of a vehicle heater, belonging to the technical field of the fuel pump rotor shaft. Background technique [0002] As an independent heating device, the fuel heater has been widely used in various vehicles, ships and other vehicles for heating in low temperature environments and engine preheating. There are currently three fuel supply methods for vehicle fuel heaters. One is to deliver fuel to the oil-absorbing liner through a low-pressure oil pump, and the fuel is evaporated and mixed with air for combustion. The second is to deliver fuel to a high-speed rotating cone by a low-pressure oil pump. On the surface of the shaped wheel, the fuel is thrown out under the action of centrifugal force and then mixed with the high-speed flow of air for combustion. Another is that the fuel is delivered to a fuel injector through a high-pressure (1MPa) oil pump to be sprayed out in mist and mix...
