Description

Technical Field

[0001] The utility model relates to the technical field of motor production, in particular to a batch clamping tool for bearings used in assembling automobile urea pump motors. Background Art

[0002] The automobile urea pump motor plays a vital role in the automobile exhaust treatment system. First of all, the main function of the automobile urea pump motor is to drive the urea pump to deliver the urea solution to the exhaust treatment device. This operation is particularly critical in the emission control system of modern diesel vehicles, because the urea solution can react chemically with the nitrogen oxides in the exhaust gas, converting them into harmless nitrogen and water vapor, thereby effectively reducing the pollutant emissions in the exhaust gas. Specifically, when the diesel engine is running, the urea pump motor starts to work and drives the urea pump to extract the urea solution. Through a special pipeline system, these solutions are accurately delivered to the injection device of the exhaust treatment device. There, the urea solution is injected into the high-temperature exhaust gas, reacts chemically with the nitrogen oxides, and purifies the exhaust gas. In addition, the automobile urea pump motor also needs to have high stability and reliability. Because the urea pump needs to work continuously for a long time and the working environment is relatively harsh, the motor must be able to withstand these challenges to ensure the stable operation of the urea pump.

[0003] Bearing clamping tooling is often required in the assembly process of automobile urea pump motors. The traditional bearing clamping tooling used in automobile urea pump motor assembly has shortcomings when used. First, it cannot clamp a single bearing and cannot achieve batch clamping of bearings, which affects assembly efficiency; second, it cannot quickly release the bearing when transferring the bearing to the assembly station.
