Abstract

The invention discloses an automobile brake drum drilling tool. A brake drum is a component used for generating braking force for hindering automobile movement or movement tendency in a braking system. Almost all automobile brakes, except various retardance devices, are friction brakes which utilize friction between the working surface of a fixed element and the working surface of a rotary element to generate a braking moment. The invention provides an internal centring drilling tool used for drilling a brake drum connection screw hole. The automobile brake drum drilling tool consists of a fixture body 1, a cushion block 2, a cone seat 3, a cover plate 4, a locking nut 5, a cone 6, an expanding core 7, a pin 8, a spring 9 and an oil cylinder 10. The automobile brake drum drilling tool has the characteristics of high precision, big clamping force and convenience in assembling and disassembling workpieces.

Description

A kind of automobile brake drum drilling tool
Technical field
Automobile brake drum is the part that mechanical processing industry is common.It is mainly used in the braking of heavy load truck.The present invention is a kind of frock solving brake rim boring.
Background technology
Brake drum is in order to produce to hinder the parts of vehicle movement or movement tendency brake force in brakes.Automotive brake, except various retarding devices, is nearly all the friction brake of the friction generation braking moment utilizing retaining element with rotating element manipulation surface.The present invention provides centering drilling tool in one, for the drilling in brake rim attachment screw hole.
Summary of the invention
The present invention utilizes oil cylinder to realize hydraulic clamp, and clamping force is big, easy to operate.Utilizing cone to rise core, feel relieved, cushion block adopts one section of supports, one section of design hollowed out, and for chip removal, drill bit leaves certain gap after passing sky.
Scheme implementation:
Embodiment 1: start Hydraulic Station, workpiece is contained in frock, presses clamping button, oil cylinder pulls down, cone pulls downward on, and the core that rises is to protruding, it is achieved the centering of workpiece and clamping, after having holed, pressing release button, oil cylinder piston moves upward, and cone is upwards, spring rebounds the core that rises, and a fabrication cycles completes.
Accompanying drawing illustrates:
Fig. 1 is a kind of automobile brake drum drilling tool.
