Description

Grinding machine convenient for cleaning scrap brake pad

Technical Field

The invention relates to the technical field of grinding machines, in particular to a grinding machine for machining a brake pad convenient for cleaning scraps.

Background

A grinding machine is a machine tool that grinds the surface of a workpiece using a grinding tool. Most grinding machines perform grinding using a grinding wheel rotating at a high speed, and a few grinding machines perform grinding using oilstones, sanding belts and other grinders and free abrasives, such as honing machines, superfinishing machines, sanding belt grinders, grinding machines, polishing machines, and the like. The grinder can process materials with higher hardness, such as hardened steel, hard alloy and the like; brittle materials such as glass, granite, etc. can also be processed. The grinding machine can grind with high precision and small surface roughness, and can grind with high efficiency, such as strong grinding. The grinding machine used in standard machining and the grinding wheel motor all operate according to a traditional starting circuit. The motor runs at a rated rotating speed after being started, the friction load of the grinding wheel workpiece is constantly changed due to certain fluctuation of the voltage of a power grid, the rotating speed error of the motor can be influenced, a standard grinding wheel motor starting circuit generally only has one machining speed and is difficult to adapt to different machining relative linear speeds required by different sizes of workpieces, and the machining precision of the machined workpieces is difficult to guarantee.

Grinding processing is widely applied and is one of the main methods for precision machining of machine parts. However, because the rotating speed of the grinding wheel of the grinding machine is very high, the grinding wheel is hard and brittle and cannot be subjected to heavy impact, and the grinding wheel is crushed due to accidental misoperation, so that very serious results can be caused. In addition, fine sand and metal chips splashed from the workpiece of the grinding wheel during grinding damage the eyes of workers, and if the workers inhale a large amount of dust, the workers are harmful to the bodies and should take appropriate protective measures.

Grinding machine is when the work piece of polishing, can produce more sweeps, general sweeps directly falls on the workstation, can influence the clean and tidy of workstation, still can fall ground in the course of the work even, influence near environment, and accumulational sweeps is taken up easily by the air current and is inhaled by the workman, influence healthy, but current clearance sweeps measure, still generally clear up the desktop by the manual work in the later stage, it is comparatively troublesome, the operating time has been wasted, and some dust collector now only set up the dust catcher beside the desktop, to the great whole workstation of area, need comparatively powerful air exhauster, it is not energy-conserving enough, still can influence workman's work.
