For achieving the above object by the following technical solutions: a kind of motor shaft automatic polishing machine, it is characterized in that: comprise controller, drive motors, transmission mechanism and motor shaft fixed support, described transmission mechanism comprises fixed station, movable guard, driving-belt and guide wheel, the output of the drive motors that fixed station is provided with, the rear portion of movable guard is movably connected on the fixed station, guide wheel is arranged in the middle part and front portion of movable guard, driving-belt is wrapped in the output of guide wheel and drive motors, and the bottom of movable guard is connected with the motion bar of air cylinder device; Described motor shaft fixed support is provided with the below of movable guard, is provided with sand paper on the motor shaft fixed support, and described controller is electrically connected with drive motors and air cylinder device.

Described motor shaft fixed support comprises guide rail and two loose pieces, and two loose pieces are provided with on the guide rail and are distributed in the both sides of movable guard, are provided with support at the top of loose piece, and the top of support is provided with groove, is provided with sand paper in the groove.

The both sides, front and back that described support top is positioned at groove are equipped with spacer, and a slit is left between the plane in spacer and support top, and the described sand paper slit of spacer in the past passes through groove and from the slit of back spacer and passes.

Below described movable guard, also be provided with spacing push rod.

Side at described guide rail is provided with location-plate, the be connected backstay of a motor shaft of the locating hole place of location-plate, and backstay and guide rail be arranged in parallel.

The utility model by driving-belt on the movable guard and motor shaft fixed support from up and down and fore-and-aft direction motor shaft is positioned, and drive motor shaft by the friction of driving-belt and rotor surface and rotate at a high speed, make sand paper on motor shaft and the motor shaft fixed support rub to finish polishing to motor shaft, whole polishing process is finished on machine automatically need not manually-operated, the workman only need be placed into polished motor shaft back startup on the motor shaft fixed mount, perhaps after polishing is finished, motor shaft is taken away from the motor shaft fixed mount, operated quite easy.

Description of drawings

Fig. 1, structural representation of the present utility model; The structural representation of Fig. 2, the utility model other direction; Structural representation when Fig. 3, the utility model polishing operation; The structural representation of other direction when Fig. 4, the utility model polishing operation.

The specific embodiment

Shown in Fig. 1-4, a kind of motor shaft automatic polishing machine, comprise controller, drive motors 1, transmission mechanism 2 and motor shaft fixed support 3, described transmission mechanism comprises fixed station 21, movable guard 22, driving-belt 24 and guide wheel 23, the output of the drive motors 1 that fixed station 21 is provided with, the rear portion of movable guard 22 is movably connected on the fixed station 21, there are two guide wheels 23 to be separately positioned in the middle part and front portion of movable guard 22, driving-belt 24 is wrapped in the output of two guide wheels 23 and drive motors 1, the bottom of movable guard 22 is connected with the motion bar of air cylinder device 4, also is provided with spacing push rod 5 below movable guard 22; Described motor shaft fixed support 3 is provided with the below of movable guard 22 and between two guide wheels 23, described motor shaft fixed support 3 comprises guide rail 31 and two loose pieces 32, two loose pieces 32 are provided with in the guide rail 31 and are distributed in the both sides of movable guard 22, be provided with support 33 at the top of loose piece 32, the top of support 33 is provided with groove 35, both sides, front and back at groove 35 are equipped with spacer 36, leave a slit between spacer 36 and the plane, support 33 top, sand paper 34 slit of spacer in the past passes through groove 35 and from the slit of back spacer again and passes, side at described guide rail 31 is provided with location-plate 37, the be connected backstay 38 of a motor shaft of the locating hole place of location-plate 37, backstay 38 be arranged in parallel with guide rail 31; Described controller is electrically connected with drive motors 1 and air cylinder device.
