Abstract
The utility model provides a handheld electric grinder which comprises a shell (1), wherein a motor (2) and a grinding wheel shaft (4) with a grinding wheel (3) are arranged in the shell (1). The handheld electric grinder is characterized in that the motor (2) adopts DC; the grinding wheel (3) is arranged at one end of the grinding wheel shaft (4); and the other end of the grinding wheel shaft (4) is connected with a main shaft (6) of the DC motor through a coupling (5). The utility model has the advantages of simple structure and light weight. With the handheld electric grinder, the safety of operators can be ensured, the work intensity of the operators is reduced, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of electronic sanding and polishing instrument, particularly a kind of hand electric abrasive machine.
Background technology
Electric wheel on the existing market all is to adopt alternating current generator as power source, and there is following shortcoming in alternating current generator: 1, institute's working voltage is at least the high-tension electricity of 220V, and is from security standpoint, safe not enough.2 adopt alternating current generator, its motor speed can not be adjustable continuously, in order to address this problem, a lot of producers set up frequency converter on abrasive machine, but for the hand electric emery wheel, after having set up frequency converter, weight has increased (national regulation, the weight of hand electric emery wheel are less than 6 kilograms) accordingly, and the operator relatively expends muscle power like this, improve labour intensity, reduced efficiency.
The utility model content
The purpose of this utility model just provides a kind of security performance height, lightweight hand electric emery wheel.
The purpose of this utility model is to realize by such technical scheme, a kind of hand electric abrasive machine, comprise shell, be provided with motor and the grinding wheel spindle that has emery wheel in the enclosure, described motor is a direct current generator, described emery wheel is arranged on an end of grinding wheel spindle, and the other end of grinding wheel spindle is connected with the direct current generator main shaft by shaft joint.
In order to prevent abrasive machine when polishing, dust disperses, and the emery wheel position is provided with guard shield relatively on the outer wall of shell front portion.
In order to reduce the operating temperature of direct current generator, describedly be provided with electric motor fan at the direct current generator spindle end.
Further, described direct current generator setting middle part in the enclosure, the afterbody of described direct current generator is provided with power line, and described power line runs through the shell afterbody and passes the shell afterbody.
In order to prevent to skid, the outer wall of described shell afterbody is provided with gum cover.
Owing to adopted technique scheme, the utlity model has simple in structure, lightweight advantage, adopt it can make operator's security be guaranteed, simultaneously, the labour intensity that it has also reduced the operator has improved efficiency.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of hand electric abrasive machine, comprise shell 1, in shell 1, be provided with motor 2 and the grinding wheel spindle 4 that has emery wheel 3, described motor is 2 direct current generators, described emery wheel 3 is arranged on an end of grinding wheel spindle 4, and the other end of grinding wheel spindle 4 is connected with direct current generator main shaft 6 by shaft joint 5.
The utility model adopts direct current generator as power source, and its voltage is 48V, is to be under the safe voltage, and operator's safety has obtained guarantee, simultaneously, behind the employing direct current generator, does not just need to be provided with frequency converter, has reduced the overall weight of abrasive machine.
Emery wheel 3 positions are provided with guard shield 7 relatively on the outer wall of shell 1 front portion.The purpose of doing like this is in order to prevent that when polishing or cutting dust disperses, and environment is polluted everywhere.
Describedly be provided with electric motor fan 8 at direct current generator main shaft 6 ends.Do the temperature that has reduced motor like this, prolonged the service life of motor.
Further, described direct current generator 2 is arranged on the middle part in the shell 1, and the afterbody of described direct current generator 1 is provided with power line 9, and described power line 9 runs through shell 1 afterbody and passes shell 1 afterbody.
The outer wall of described shell 1 afterbody is provided with gum cover 10.The purpose of gum cover 10 is in order to prevent that operator's abrasive machine when operating from skidding.
