A method of manufacturing a windshield wiper gearbox housing

Abstract

A method for manufacturing a windscreen wiper reduction gearbox shell comprises the following steps that multiple nonstandard tools are sequentially installed on the circumference of a rotary tool magazine of a machine tool in a machining center, the windscreen wiper reduction gearbox shell is installed on a rotary fixture, rough milling and finish reaming are conducted on an output shaft hole in a 0-degree state, rough milling, finish reaming and tapping are conducted on a threaded hole in a 270-degree state, finish milling and grooving are conducted on a motor installation end face in a 90-degree state, and finish milling is conducted on a motor shaft step hole. The method has the advantages that the rotary fixture is used for clamping a workpiece, switching between the 0-degree state, the 90-degree state and the 270-degree state can be conducted, repeated clamping is not needed, multiple times of locating is avoided, the machining accuracy is high, clamping time is saved, machining time is short, and production efficiency is high; by the adoption of the rotary tool magazine, tool replacement time is shortened, machining time is shortened, and production efficiency is further improved; all tools used in each step are special tools, so that the machining accuracy is higher.

Description

technical field [0001] The invention relates to a manufacturing method of a windshield wiper reduction box housing. Background technique [0002] The existing windshield wiper reducer housing needs to finish the step hole of the motor shaft, the end face of the motor installation, the output shaft hole and the threaded hole, and in the process of processing, the output shaft hole is generally processed first, and then rotated 90 degrees Afterwards, the motor installation end face and the step hole of the motor are processed, and then the threaded hole is processed after rotating 90 degrees. This requires multiple clamping and multiple positioning of the product, so that the processing accuracy of the product cannot be guaranteed, which seriously affects the wiper. performance, and the processing time is prolonged due to multiple clamping, which increases the input cost. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior a...
