Abstract

The utility model discloses a sand tray belt sander comprising a main work table, an engine base located on one side of the main work table, a bearing bracket loaded on the engine base, a motor loaded on the engine base and adjacent to the bearing bracket, a sand tray protective cover connected with the motor and driven by the motor, and a sand tray installed on the sand tray protective cover, and a gap is arranged between the bearing bracket and the motor to reduce the mutual vibration effect of the bearing bracket and the motor and reduce the vibration between the sand tray and the sand tray protective cover so as to avoid the collision between the sand tray and the sand tray protective cover.

Description

Abrasive disk abrasive belt machine

Technical field

The utility model relates to the grinding field, especially a kind of abrasive disk abrasive belt machine with improvement structure.

Background technology

Existing abrasive disk abrasive belt machine structure mainly comprises support, motor and the support of bearing fixed on the support, the main table assembly that the support of bearing one side connects through major axis, intrinsic driven three horn rings and emery disc on the support of bearing opposite side major axis, the interior guard shield of belt pulley that support of bearing opposite side is fixing, the emery disc guard shield of fixing on the belt pulley outer shield, during work, when main table assembly is attached to support of bearing side surface rotary around major axis, pivot is subjected to the gap between square neck screw and the support of bearing kidney slot, the impacts such as two kidney slot concentricitys, pivot produces displacement thereupon, the major axis of main table assembly is corresponding generation displacement also, because driven three horn rings and emery disc are contained on the major axis, so emery disc and driven three horn rings also produce displacement; Because the emery disc guard shield is directly to be fixed on the belt pulley outer shield, and guard shield directly is fixed on the support of bearing in the belt pulley, so when main table assembly rotation, they can not move all the time; Because the gap between guard shield, emery disc and the emery disc guard shield is smaller in driven three horn rings and the belt pulley, when the machine works state, strike note is continuous again.

So, need a kind of new technical scheme to address the above problem.

The utility model content

The purpose of this utility model is the deficiency that exists for prior art, and a kind of novel abrasive disk abrasive belt machine of working stability is provided.

For achieving the above object, the utility model abrasive disk abrasive belt machine can adopt following technical scheme:

A kind of novel abrasive disk abrasive belt machine, comprise main workbench, be positioned at main workbench one side support, be carried on the support of bearing on the support, be carried on the support and the motor adjacent with the support of bearing, be connected with motor and by motor-driven emery disc guard shield and be installed on emery disc on the emery disc guard shield, be provided with the gap between the described support of bearing and the motor.

Compare with background technology, the novel abrasive disk abrasive belt machine of the utility model is by being provided with the gap between the described support of bearing and motor, reduced vibration effect mutual between the support of bearing and the motor, vibration between emery disc and the emery disc guard shield is reduced, thereby avoid the bump between emery disc and the emery disc guard shield.

Preferably, the distance in described gap is 5mm, the clearance distance of this 5mm is to avoid the minimum range of clashing between emery disc and the emery disc guard shield, can make the width of abrasive disk abrasive belt machine minimum when avoiding clashing between emery disc and the emery disc guard shield, is conducive to the abrasive disk abrasive belt machine miniaturization.

Preferably, be provided with the yielding rubber layer between the described support of bearing and the motor, thus can the more effective minimizing support of bearing and motor between mutual vibration effect.

Description of drawings

Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model abrasive disk abrasive belt machine.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.

See also shown in Figure 1, the utility model discloses a kind of novel abrasive disk abrasive belt machine 100, comprise main workbench 2, be positioned at main workbench 2 one sides support 3, be carried on the support of bearing 4 on the support 3, be carried on the support 3 and the motor 5 adjacent with the support of bearing 4, be connected with motor 5 and the emery disc guard shield 6 that driven by motor 5 and be installed on emery disc 7 on the emery disc guard shield 6.Be fixed with initiatively three horn rings 54 on the axle of described motor 5, driven three horn rings 61 are installed on the described emery disc guard shield 6, described active three horn rings 54 and driven three horn rings 61 connect by belt (not shown).Be provided with the gap between the described support of bearing 4 and the motor 5, preferably, the distance in described gap is 5mm, through overtesting, the clearance distance of this 5mm is to avoid the minimum range of clashing between emery disc and the emery disc guard shield, avoiding to make the width of abrasive disk abrasive belt machine 100 minimum between emery disc 7 and the emery disc guard shield 6 in the bump, be conducive to abrasive disk abrasive belt machine 100 miniaturizations.

It more than is the first embodiment of the present utility model, in other embodiments of the present utility model, can also further be provided with the yielding rubber layer between the described support of bearing and the motor, thus can the more effective minimizing support of bearing and motor between mutual vibration effect.
