Abstract

The invention provides a pneumatic drill fixture for machining a wheel hub. The pneumatic drill fixture comprises a mounting base plate; a main positioning pin, a secondary positioning pin and a clamping device are arranged on the mounting base plate, wherein the main positioning pin is in a cylindrical shape matched with an axle hole of the wheel hub; the secondary positioning pin has a side matched with the edge of a window hole of the wheel hub; the clamping device comprises a pressing block and an air cylinder; one end of the air cylinder is connected with the pressing block; the other end of the air cylinder is fixedly connected with the mounting base plate; the wheel hub can be precisely positioned on the drill fixture by positioning of the main positioning pin and the secondary positioning pin; subsequently the outer circumference of the wheel hub is clamped so that wheel hub can be fixed for further machining; moreover, clamping is executed by a pneumatic element, so quick and convenient machining is realized, and the wheel hub is high in repeated positioning accuracy and is convenient to mount and dismount.

Description

technical field [0001] The invention relates to a drilling jig, in particular to a pneumatic drilling jig for processing a wheel hub. Background technique [0002] The wheel hub is an important part of the car. The car tire itself is soft, and the inner profile of the tire supports the drum-shaped structure of the tire, which is called the wheel hub. [0003] The existing wheel hub processing is generally performed on a vertical machining center for drilling. However, the current drilling jig has a complex structure, which makes it inconvenient to assemble and disassemble the wheel hub, and the repeat positioning accuracy of the drilling jig is low and the clamping is cumbersome. Contents of the invention [0004] The technical problem to be solved by the present invention is: the structure of the current drilling jig is complex, the assembly and disassembly of the wheel hub is inconvenient, and the repeated positioning accuracy of the drilling jig is low and the clamping ...
