Abstract

The utility model discloses a grinding disc of floor grinding machine, which comprises a chassis, a grinding disc, a damping spring, an I-shaped flange and a rubber buffer cushion; the chassis, the rubber buffer cushion and the I-shaped flange are sequentially connected together through pins; circular holes are respectively machined in the centers of the chassis, the rubber buffer cushion and theI-shaped flange; the damping spring is mounted in the circular holes and the grinding disc is fixed on the lower disc of the I-shaped flange. Compared with rubber disc connection in prior art, the grinding disc of floor grinding machine has safer and more reliable design, is abrasion resistant and high temperature resistant, and has long service life; besides, the grinding disc of floor grinding machine has the advantages of simple structure, good damping effect and stable operation.

Description

The mill of floor grinding mill

Technical field

The utility model relates to processing of stone machinery field, relates in particular to a kind of mill of floor grinding mill.

Background technology

At present, in order to adapt to the grinding of rough and uneven in surface stone plane, reduce vibration, reduce noise, improve Grinding Quality, be extensive use of the rubber-like bistrique.A kind of Spring grinding head of prior art, it comprises the chassis, rubber disc, damping spring and mill, mill is fixed on the rubber disc by three studdles, rubber disc is fixed on the chassis by three studdles again, in the rubber disc mesopore between mill and chassis damping spring is set, because the effect of rubber disc and damping spring makes this bistrique have shock-absorbing function, but, the chassis of this damping bistrique and mill connect by a rubber disc, and it exists rubber disc easy deformation, non-refractory, caoutchouc elasticity is lax after using a period of time, the bistrique instability comes off easily, poor stability.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of prior art, a kind of simple in structure, good damping effect is provided, operates steadily, the mill of long service life, safe and reliable floor grinding mill.

The purpose of this utility model is achieved in that a kind of mill of floor grinding mill, it comprises the chassis, mill and damping spring, it is characterized in that: it also comprises I-shaped flange and rubber buffer, there is the interface that connects with transmission mechanism upper end, described chassis, the chassis, ring-type pin hole that evenly distributes all on the last disk of rubber buffer and I-shaped flange, on pin hole, wear pin and tightening nuts successively with the chassis, rubber buffer and I-shaped flange are linked together, the chassis, all there is circular hole at the center of rubber buffer and I-shaped flange, damping spring is installed in circular hole, and described mill is fixed on the lower disc of I-shaped flange by screw.

Ring-type three pin holes that evenly distribute all on the last disk of described chassis, rubber buffer and I-shaped flange are put on pin and tightening nuts and successively chassis, rubber buffer and I-shaped flange are linked together on pin hole.

The utility model is compared its advantage and is with prior art: the ring-type pin hole that evenly distributes on the last disk of chassis, rubber buffer and I-shaped flange, wearing pin and tightening nuts on pin hole is linked together chassis, rubber buffer and I-shaped flange successively, this connection connects safety and reliability than prior art by rubber disc, wear-resistant, high temperature resistant, long service life; The diameter of described pin is less than the diameter of pin hole, rubber buffer can be extruded distortion and play the elastic buffer effect when bistrique is under pressure, in order to increase elastic limit and dynamics, in the center hole of chassis, rubber buffer and I-shaped flange damping spring is installed, this project organization is simple, good damping effect, operate steadily.
