Abstract

The utility model discloses a polishing machine. A drive gear is driven by a motor; then, a rotating shaft which is provided with a polishing disk is driven for rotation through the engagement of gears; a follower gear on the rotating shaft simultaneously drives the other root of a rotating shaft which is provided with a polishing disk to rotate through the engagement of the gears. Because the two polishing disks reversely rotate, the torques of the two polishing disks are opposite, the swing of the polishing machine during work can be reduced, and simultaneously the work efficiency can be increased, and a speed-changing box is additionally arranged between the motor and the drive gear for changing the rotating speed of the polishing disks. The gear driving relative to the conventional belt driving is adopted for the higher driving efficiency, and the polishing machine with more than the two polishing disks can be formed according to requirements.

Description

A kind of sanding machine

The utility model relates to a kind of sanding machine that is used to build polishing usefulness.

General sanding machine all is single mill, and when working owing to the sanding machine of single mill, working face produces reverse torque to bistrique, drives the complete machine swing, and is very painstaking during operation.

The purpose of this utility model is can effectively weaken work swing, the sanding machine of being convenient to operate in order to provide a kind of.

Main technical schemes of the present utility model is: sanding machine of the present utility model comprises body, be fixed on motor on the body, be installed in the rotating shaft that has mill on the body, rotate by the driven by motor driven wheel, driven gear engagement in driven wheel and the rotating shaft, another root rotating shaft that is installed on the body also has mill and time driven gear, the follower gear engagement in inferior driven gear and the last rotating shaft.

After adopting this structure, motor drives the switched in opposite of two mill work and mill simultaneously, and working face is also opposite to the effect torque of mill like this, thus the swing of sanding machine when weakening work, reduce manipulation strength, simultaneously two mill work can improve grinding efficiency.Simultaneously, adopt this version can be combined into two sanding machines as required with upper millstone.

Fig. 1 is the structure chart of an embodiment of a kind of sanding machine of the present utility model;

Fig. 2 is the partial sectional view of a kind of sanding machine shown in Figure 1;

Fig. 3 is the structure chart of another embodiment of a kind of sanding machine of the present utility model;

Fig. 4 is the left view of a kind of sanding machine shown in Figure 1;

Fig. 5 is the structure chart of another embodiment of a kind of sanding machine of the present utility model.

As shown in Figure 1, sanding machine comprises body 6, is fixed on motor 1 on the body, is installed in the rotating shaft that has mill 84 on the body 6, motor 1 drives driven wheel 3 rotations, between motor 1 and driven wheel 3, be connected with gearbox 2, driven gear 5 engagements in driven wheel 3 and the rotating shaft 4, another root rotating shaft 9 that is installed on the body also has mill 10 and time driven gear 11, follower gear 7 engagements in inferior driven gear 11 and the rotating shaft 4.Speed change was convenient when the gearbox of installing on sanding machine made sanding machine work, increased work efficiency.

Another embodiment is based on first embodiment.There is detachable end 12 at the two ends of body 6, form assembled unit 14 by casing 13 and the rotating shaft that has mill and gear that is installed on the casing, casing 13 is connected on the body 1 that unloads bottom end cover, gears engaged in gear in the casing 13 and the body 1, the end cap that closes has then just been formed the sanding machine of three mills.Therefore be that the basis is loaded onto assembled unit and just can be formed two sanding machines with upper millstone are arranged with the sanding machine of two mills.Swing when certainly, the even number mill will help more effectively weakening sanding machine work.

As shown in Figure 4, among the 3rd embodiment of the present utility model, the motor 1 on the body 6 directly drives the rotating shaft 4 that has mill 8 and rotates, and 15 in another motor on the body 6 directly drives rotating shaft 9 backward rotation that have mill 10.So also can make sanding machine that less swing is arranged.
