Test bench for runout detection of electronic water pump

Abstract

The invention relates to a test bench for the runout detection of an electronic water pump. The test bench comprises a rack and a conveyor belt, wherein a tray is arranged on the conveyor belt; a profiling base is fixed on the upper end surface of the tray; a wide-type air claw and a lifting cylinder, the output end of which is connected with the wide-type air claw, are arranged at the left side of the profiling base; arm plates are connected on the wide-type air claw; semi-circular clamping boards are connected at one sides, which are close to the profiling base, of the arm plates; a rubber circular block is arranged above the profiling base and connected with a motor; the motor is connected with a sliding seat vertically sliding on the rack; a displacement sensor is arranged at the lowerside of the sliding seat; a downward pushing cylinder is connected at the upper side of the sliding seat; a distance sensor and a leftward pushing cylinder are arranged at the right front side of thetray; the leftward pushing cylinder is connected with a limit block; and a PLC (Programmable Logic Controller) controller for controlling the operation of the device is arranged on the rack. The testbench disclosed by the invention has the beneficial effects that the online runout detection of an impeller rotor on the electronic water pump is realized through the displacement sensor, so that thelabor intensity is greatly reduced and the work efficiency is improved; and the test bench has the advantages of high detection precision and accuracy.

Description

technical field [0001] The invention relates to the technical field of electronic water pumps, in particular to a test bench for detecting the jumpiness of electronic water pumps. Background technique [0002] At present, in the assembly process of electronic water pumps, in order to ensure the quality of the product and the stability of the internal impeller in the later stage, it is necessary to detect the runout of the impeller before assembly. The traditional method is to detect the runout by manually rotating the impeller. However, this method has inaccurate detection results due to uneven artificial force, and the whole process is labor-intensive and low-efficiency, so as to provide a stable and effective detection method, it seriously affects the pass rate of the product, which is not conducive to the development of electronic water pumps. Assembly production. Contents of the invention [0003] In order to avoid and solve the above-mentioned technical problems, the...
