Abstract

The utility model relates to a safe abrasion machine which belongs to grinding mechanism. The abrasion machine comprises a motor 1, a bearing pedestal housing 7 fixedly connected with the end portion of the motor, a bearing 8 inside the housing, abrasion wheels 9 arranged on the motor shaft 6 at intervals, a wheel protection cover 10, and a base 14, wherein a plurality of baffles 12 are provided inside the protection cover, fixedly connected with the inner wall of the protection cover at one end and inclined upwards at the other end in a direction opposite to the rotation direction of the abrasion wheels; and a wind and sand discharge port 13 is provided on the bottom of the protection cover. The motor 1 has a square housing 2, and the motor stators 4 are fixed through a support plate 3. The bearing pedestal housing 7 is provided with two bearings 8 and 8'. The safe abrasion machine can effectively prevent splash of grinding sands, debris, and wheel shivers from flying off to hurt people, and can improve the rotation speed of the abrasion wheels, thereby improving safety and working efficiency. The double-bearing design increases the length of the rotation shaft of the motor and prevents the occurrence of deformation, and the square motor housing and the gap between the stators facilitate heat dissipation of the motor.

Description

The safe grinding wheel machine

Technical field: the utility model relates to abrasive machine, is a kind of safe grinding wheel machine that is used for sand milling processing.

Background technology: existing abrasive machine is to be made of bearing, its axle head installation emery wheel and guard shield that motor, rotor beam warp are loaded in the bearing block housing, guard shield is provided with opening in the face of the worker, expose emery wheel so that processing, existing emery wheel has three point defects: the one, and the sand grains that produces in the grinding process, chip, perhaps the process medium plain emery wheel is in case the broken emery wheel fragment that produces etc., flown out at a high speed by the guard shield opening part, very easily hurting sb.'s feelings causes the accident; The 2nd, mostly abrasive machine is that the motor shaft two ends are equipped with processing grinding wheel, can two people work simultaneously, require that preferably machine shaft is longer, to avoid influencing each other of two people processing, and existing abrasive machine rotating shaft is shorter, if it is unstable that lengthening easily produces the deformation and the operation of axle again: the 3rd, the prior motor shell is round, and the motor stator suit is fixed in the circular housing, and stator three heat are bad.

Summary of the invention: goal of the invention of the present utility model, be to take new technical measures, overcome the defective of existing abrasive machine, a kind of safe grinding wheel machine is provided, it can effectively avoid frosted, chip, emery wheel fragment to be flown out by the guard shield opening part hurting sb.'s feelings; Make the rotor axis of electric lengthening and do not produce deformation; And make motor radiating good.

For reaching the technical measures that above-mentioned purpose takes be, the safe grinding wheel machine comprises motor 1, with the affixed bearing block housing 7 in motor end, be loaded on the interior bearing of housing 8, be loaded on emery wheel 9, wheel-guard 10 and base 14 on the motor shaft 6, be provided with polylith baffle plate 12 in the wheel-guard, the one end is fixed in the guard shield inwall, its other end is oblique, the direction of sensing and emery wheel switched in opposite, and and emery wheel between have the gap.The guard shield bottom is provided with air-discharging sand removing hole 13.Motor 1 has square shell 2, through gripper shoe 3 fixed electrical machinery stators 4.Be provided with in the bearing block housing 7 two bearings 8 and 8 '.

This safe grinding wheel machine because design has curved baffle in the guard shield, can effectively be avoided frosted, chip, emery wheel fragment to be flown out by the guard shield opening part and hurt sb.'s feelings, and is safe in utilization, and grinding wheel speed can be improved, and improved operating efficiency; The duplex bearing design, the machine shaft length that can extend, and be unlikely to produce distortion; Motor housing is square, and the space is arranged between stator, is beneficial to motor radiating.
