Description
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.

Fig. 2 is a schematic diagram of the matching of the internal gear and the external gear in the present invention.
Detailed Description
Referring to fig. 1 and 2, the polishing device provided by the present invention comprises a frame 9, a polishing output shaft 2 fixed on the frame 9, an internal gear 5 coaxially mounted with the polishing output shaft 2, and a gear seat 1 for fixing the internal gear 5, wherein an eccentric bearing seat 3 is fixed at one end of the polishing output shaft 2, the eccentric bearing seat 3 is provided with an autorotation shaft 7 connected with a polishing disk 6 through a bearing 8, the autorotation shaft 7 and the polishing output shaft 2 are parallel to each other but not concentric, the eccentricity is N, and the other end of the polishing output shaft 2 passes through the frame 9 and is connected with a rotation driving device arranged at the other side of the frame 9; the polishing machine is characterized in that the internal gear 5 is fixed on one side of a rack 9 through a gear seat 1, an external gear 4 coaxial with the rotation rotating shaft 7 is fixed on the rotation rotating shaft 7, the internal gear 5 is a fixed gear, the external gear 4 rolls along the internal gear of the internal gear 5 through the meshing of external teeth and the internal teeth of the internal gear 5, the center distance between the external gear 4 and the internal gear 5 is equal to the eccentric distance N between the rotation rotating shaft 7 and the polishing output shaft 2, and the eccentric distance N between the rotation rotating shaft 7 and the polishing output shaft 2 can be adjusted according to the center distance between the external gear 4 and the internal gear 5.
During polishing, the polishing output shaft 2 is power output, when the polishing output shaft drives the eccentric bearing seat 3 to rotate at a high speed, the rotation rotating shaft 7 and the external gear 4 are simultaneously driven to perform eccentric revolution and simultaneously generate rotation motion, the external teeth of the external gear 4 are always meshed with the internal teeth of the internal gear 5 during rotation and revolution, and the rotation speed of the rotation rotating shaft 7 is always controlled to be a stable value due to relative rolling of the internal gear 4 and the external gear 5, so that the polishing output shaft is not influenced by polishing pressure change.
The external gear 4 and the internal gear 5 are detachable structures, gear sets with a plurality of transmission ratios and different center distances can be configured according to the requirement of the rotation speed of the polishing wheel in actual production for disassembly and replacement so as to meet different process requirements, the eccentricity N between the rotation rotating shaft 7 and the polishing output shaft 2 is set to be adjustable so as to meet different center distances, and a U-shaped groove is arranged at the joint of the eccentric bearing seat 3 and the rotation rotating shaft 7.
