Problems solved by technology

[0003] However, the commonly used sanding machine has a high profile, and the distance between the operator's palm and the operating surface or the sand table is relatively long.
It is not conducive to the operator to precisely control the sand table to grind the workpiece, and it is easy to have deviations in the grinding position

Embodiment Construction

[0025] Please refer to figure 1 , an embodiment provides a sander 100 . The sander 100 includes a housing 110 , a motor disposed in the housing 110 , and a sanding disc 130 connected to the motor and driven by the motor to rotate for sanding. The shell 110 of the sander 100 is also provided with a fan 140 for cooling the sander 100 and sucking away the dust generated by the sander 100 . The shell 110 of the sander 100 is provided with a power cord 114 and a switch 112, the power cord 114 is connected to an external power supply to provide the sander 100 with the power required for work, and the switch 112 is used to control the opening of the sander 100 with off. The sand disc 130 of the sander 100 includes an inner sand disc 131 and an outer sand disc 132, the motor output shaft 125 drives the inner sand disc 131 to rotate through the inner sand disc eccentric shaft 133, and drives the outer sand disc through the outer sand disc eccentric shaft 134 132 spins. The inner sa...

Abstract

The invention provides a sander. The sander comprises a shell, a motor arranged in the shell, and an abrasive disk which is connected with the motor and driven by the motor to rotate for performing grinding operation, wherein the motor is an axial magnetic field motor. The axial magnetic field motor is adopted for the sander for replacing a radial magnetic field motor, because the external shape of the magnetic field motor is flat, the contour of the sander can be reduced, and therefore the palms of an operator can approach to the abrasive disk, and the operator can accurately control the grinding position of the abrasive disk conveniently.

Description

technical field [0001] The invention relates to a hand-held electric grinding tool, in particular to a sander. Background technique [0002] At present, sanding machines are widely used in the grinding and sanding of walls or floors. A sander has a motor that provides the driving force. The motor is connected to the power transmission system and is located within the housing of the sander. The sander also has a sand table, and the motor is connected to the sand table through a power transmission system. When the sander is working, the motor drives the sand disc to rotate axially around an axis to grind the surface of the workpiece to be polished so as to make it smooth and flat. [0003] However, the commonly used sanding machine has a relatively high profile, and the distance between the operator's palm and the operating surface or the sand table is relatively long. It is not conducive to the operator to precisely control the sand disc to grind the workpiece, and the de...
