Description

Hand-held square tube polisher

Technical Field

The utility model belongs to the technical field of polishing equipment, and particularly relates to a handheld square tube polishing machine.

Background

At present, a hand-held grinding machine only has one grinding wheel, and one grinding wheel only can grind one surface at a time when grinding a square tube, so that the grinding speed is slower, and the grinding speed can be improved if two surfaces can be ground at a time; the same problem exists for grinding round tubes.

Disclosure of Invention

In order to overcome the defects, the utility model provides a handheld square tube polisher.

The technical scheme who adopts in this practicality is as follows:

the hand-held square tube polishing machine comprises a first polishing grinding wheel, a second polishing grinding wheel, a handle and a driving motor, wherein a first conical gear ring is arranged at the edge of the first polishing grinding wheel, a second conical gear ring is arranged at the edge of the second polishing grinding wheel, the first conical gear ring and the second conical gear ring are meshed with each other, the middle part of the bottom of the first polishing grinding wheel is fixedly connected with a driving shaft through a connecting shaft, the driving shaft is fixedly connected with an output shaft of the driving motor, the driving motor and the driving shaft are arranged in the handle, and the driving motor is fixed inside the handle. The surfaces of the first grinding wheel and the second grinding wheel are fixed with sand paper.

The polishing plane of the first polishing grinding wheel and the polishing plane of the second polishing grinding wheel are vertically arranged.

The outer wall of second grinding wheel of polishing is provided with the mounting bracket, the one end of mounting bracket is connected through the bearing rotation with the outer wall middle part of second grinding wheel of polishing, the other end of mounting bracket and the outer wall fixed connection of protection axle sleeve.

The protection axle sleeve sets up the upper end at the handle, the upper end fixed connection of protection axle sleeve and handle, the connecting axle rotates with the protection axle sleeve to be connected, and the connecting axle is inside the protection axle sleeve.

The bottom inside the handle is provided with the group battery, and the group battery is fixed inside the handle, driving motor and group battery electric connection.

The beneficial effects are that: the handle is held, so that the polishing plane of the first polishing grinding wheel and the polishing plane of the second polishing grinding wheel are respectively attached to two planes of the square tube, and the first polishing grinding wheel and the second polishing grinding wheel are linked through the first conical gear ring and the second conical gear ring, so that the first polishing grinding wheel and the second polishing grinding wheel rotate simultaneously to polish different planes of the square tube. The polishing machine is also applicable to polishing round tubes and can also improve polishing speed.
