Description

Polishing device

Technical Field

The utility model belongs to the polishing equipment, concretely relates to burnishing device.

Background

The traditional eccentric polishing device consists of an eccentric bearing seat and a rotation rotating shaft arranged on the eccentric bearing seat, wherein the eccentric bearing seat is connected with a polishing output shaft, and the rotation rotating shaft is connected with a polishing disc and consumables. During polishing, the polishing output shaft drives the eccentric bearing seat to rotate at a high speed, and due to the inertia and the eccentric amount of the polishing disc, the polishing disc also generates autorotation motion while performing eccentric revolution, and is driven by no driving force.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a pressure stability and polishing device that can fine adjustment to the not enough of current curved surface polishing technique existence.

Realize the utility model discloses the technical scheme that the purpose was adopted as follows:

the utility model provides a burnishing device, including the polishing output shaft, with the eccentric bearing frame that polishing output shaft one end linked firmly, install the rotation pivot that is used for installing the polishing dish on the eccentric bearing frame through the bearing, still include with polishing output shaft coaxial arrangement's internal gear, be used for fixed internal gear's pinion stand, fix in the rotation pivot with the coaxial external gear of rotation pivot, the rotation pivot is parallel to each other but the decentraction with the polishing output shaft, and the eccentricity is N, the internal gear is the fixed gear, the external gear rolls with the internal gear meshing and along the internal tooth of internal gear, the centre-to-centre spacing of external gear and internal gear equals the eccentricity N of rotation pivot and polishing output shaft.

The utility model discloses still include the frame, the internal gear passes through the pinion stand to be fixed in one side of frame, the other end of polishing output shaft passes the frame and establishes at frame opposite side rotary drive device and be connected.

And the eccentricity N between the rotation rotating shaft and the polishing output shaft can be adjusted according to the center distance between the external gear and the internal gear.

Advantageous effects

The utility model discloses because set up the internal tooth roll of external gear and fixed internal gear meshing edge internal gear in the rotation pivot, during the polishing, the polishing output shaft drives rotation pivot and external gear through eccentric bearing frame and also produces the rotation motion when being eccentric revolution, its outer tooth is all the time with the internal gearing of internal gear when external gear rotation and revolution, the relative roll of inside and outside gear makes the rotation speed of rotation pivot controlled all the time, thereby obtain stable rotation speed, the rotational speed of polishing dish can not produce the change because of the pressure size of polishing, can improve polishing efficiency.

The technical scheme of the utility model is further explained in the following with the attached drawings.
