Oil injection device for central shaft of claw pole type step motor shell

Abstract

The invention discloses an oil injection device for a central shaft of a claw pole type step motor shell. The device comprises a working table, a shell feeding channel, an oil injection cylinder, an oil injection barrel, a retaining cylinder, a clamping cylinder, a pushing cylinder, a shell clamp and a shell detection sensor, wherein the shell reaches a detection position from a previous step through the shell feeding channel during work; when the shell detection sensor detects that the shell arrives, the retaining cylinder retains the shell at a fixed position, then the shell clamp extends out to clamp the shell, the retaining cylinder retracts, the pushing cylinder pushes the shell clamp forwards to the fixed position, the shell on the shell clamp is vertically opposite to an oil injection nozzle of the oil injection barrel at the time, the oil injection cylinder performs oil injection, the shell clamp retracts after the oil is injected, and the pushing cylinder returns to clamp a next shell; the work is circulated to continuously and fully automatically perform oil injection work on the central shaft of the shell; manual operation is not required, the labor is saved, the phenomenon of injected oil leakage is avoided, the reliability is high, uniform oil quantity is guaranteed, and the product quality is improved.

Description

technical field [0001] The invention relates to an oiling device for the center shaft of a claw pole type stepping motor casing. Background technique [0002] The oiling of the center shaft of the claw pole stepper motor casing is a very important process in the production process of the stepper motor. The rotor and main gear of the stepper motor need to rely on the center shaft to rotate the center shaft, and the center shaft is filled with lubricating oil It can well guarantee the service life of the motor. At present, the oiling of the center shaft of the production line is done by hand with thin wooden strips dipped in lubricating oil and then scraped on the center shaft. This method will cause uneven oil sticking area of ​​the center shaft, excessive oil quantity and insufficient oil, and oil leakage. Too much oil will cause oil leakage at the bottom of the case and affect the appearance of the nameplate, and insufficient oil will cause poor listening problems such as ...
