High-accuracy casting polishing machine

Abstract

The invention discloses a high-accuracy casting polishing machine. The high-accuracy casting polishing machine comprises a machine frame, a motor and a cutting disc, wherein the motor is arranged on the machine frame and is connected to a rotation shaft of the cutting disc through a chain. A silencer is arranged at the part, close to the cutting disc, of the middle of the machine frame. A buffering device is arranged on the bottom of the machine frame. An installation hole is formed in the center of the cutting disc, the cutting disc is provided with through holes distributed in the radial direction of the cutting disc, and the through holes extend in the peripheral direction of the cutting disc, penetrate through the two end surfaces of the cutting disc and are used for dissipating heat and dispersing stress. According to the invention, the condition that castings are damaged in manual polishing is avoided, the speed is high, the size of the cutting disc during heating expansion is guaranteed, the influence of the heat generated in work to the size of the cutting disc is lowered, the distortion degree of the cutting disc in work is lowered, the machining efficiency of the cutting disc is guaranteed, and therefore the production efficiency is improved, the production cost is lowered, the noise generated in the reoperation process is lowered, and the steadiness in work is improved.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a high-precision casting grinding machine. Background technique [0002] Castings are smelted and formed, and burrs and particles often appear on the surface, which are not only unsightly, but also affect their quality in use. The traditional way is to use manual grinding to remove burrs, particles and other problems on the surface. This is not only labor-intensive, but also manual grinding cannot evenly polish the surface of the casting. Once the operation is improper, the casting will be worn down. . Existing machines are used for grinding, but this kind of machine has a lot of noise, severe vibration and unstable operation during operation. At the same time, the cutting piece will generate high heat during the high-speed cutting process, and the heat is dissipated inside the cutting piece. Slow, resulting in too much heat inside the cutting piece, so that the cutt...
