Abstract

The invention discloses a machining apparatus. The machining apparatus comprises a worktable; a fixing plate for fixing a hub is arranged on the worktable; the fixing plate is of a plate-like structure with a circular through hole; at least two radial ribs located in the radial direction of the circular through hole are further arranged at any end of the circular through hole; the radial ribs cross with each other in the axis of the circular through hole; the machining apparatus further comprises a screw fixed in the point of intersection of the radial ribs; the axis of the screw is collinear with the axis of the circular through hole; a hold-down nut is further connected to the screw by use of threads; at least one screwdriver is arranged in each of the axial direction and the radial direction of the circular through hole; the screwdrivers are fixed on an axial drill and a radial drill, respectively. The machining apparatus is simple in structure, and advantageous for improving the efficiency and the quality of hub tapping.

Description

technical field [0001] The invention relates to the field of automobile wheel hub manufacturing equipment, in particular to a machining equipment. Background technique [0002] The wheel hub of automobile in the prior art can be divided into steel wheel hub and alloy wheel hub two big classes according to material. The main advantage of steel wheels is that the manufacturing process is simple, the cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and strong. However, the disadvantages of steel wheels are also relatively prominent, that is, ugly appearance, heavy weight, large inertial resistance, poor heat dissipation, and very easy to rust. Relatively speaking, alloy wheels can just make up for such problems. The weight and inertial resistance are small, the manufacturing precision is high, the deformation at high speed rotation is small, and the inertial resistance is small, which is beneficial to improve ...
