The utility model relates to a special drilling and tapping machine for wheel flange, which is composed of an external mounting cylinder and an internal main engine; the main engine can move axially along the inner cavity of the mounting cylinder under the action of a gear rack mechanism; one end of the main engine is equipped with a motor, the other end is equipped with a swing head, and the motor finally drives the chuck at the end of the swing head to rotate through a gearbox, a coupling, etc. There is also a transmission system in the swing head to adjust the output speed of the chuck according to the need. The swing head can also adjust the position of the chuck according to the diameter of the distribution circle of the screw hole to be processed to meet different processing needs. The utility model relates to a special drilling and tapping machine for wheel flange, which is installed in the wheel flange seat when used. By adjusting the angle, the screw holes on the flange can be drilled and tapped one by one. The operation is convenient, the reliability of drilling and tapping is greatly improved, and the subsequent wheel installation work is more convenient, and the manpower and material resources are saved.

车轮法兰钻孔攻丝专机
本技术涉及一种钻孔、攻丝专业机械领域,特别是一种可在半圆形法兰上进行钻孔攻丝的专机。
技术介绍
轮胎吊小车架车轮排装时,车轮固定方式是与小车架车轮法兰螺栓连接,车轮法兰需预先进行钻孔、攻螺纹。如图1、图2所示,需要在两侧的法兰1上进行钻孔、攻丝,形成螺纹孔2用于安装,一直以来都是采用风钻或磁铁钻进行钻孔,然后再进行人工攻丝,费时费力;且稍有不甚,就会导致钻歪,断钻头、丝锥等,且钻孔过程中不稳定,导致底孔尺寸不均,之后攻丝的螺孔质量差,给后续的安装带来了很大的困难,非常耗费工时。目前市场上有一些可用于管道整圆法兰钻孔攻丝的机具,但都需要采用内壁支撑,或外侧抱住的方式进行,而轮胎吊小车的车轮法兰为半圆形,很难在其上架设用于整圆法兰钻孔攻丝的机具,故为了提高加工效率,有必要设计一款可在半圆形车轮法兰上进行钻孔、攻丝的专机。
