Still further preferably, a plurality of pressing plates are uniformly arranged above the outer edge of the workpiece carrying disc, and the lower surfaces of the pressing plates are used as the upper limiting parts.
In the above scheme, the at least three gears are driven by the same servo motor to synchronously rotate.
In the scheme, at least two positioning holes are formed in the workpiece carrying disc, and two positioning tools are arranged corresponding to the two positioning holes; the positioning tool is a rod-shaped body, one end of the rod-shaped body is provided with a pin hole, and the other end of the rod-shaped body is provided with a positioning pin part which extends downwards; the frame is provided with a cylindrical pin extending upwards, the end part of the positioning tool is sleeved on the cylindrical pin through a pin hole, the other end of the positioning tool extends to the upper part of the workpiece carrying disc, and the positioning pin part of the positioning tool is correspondingly embedded and matched with the positioning hole.

In order to achieve the purpose, the technical scheme of the method adopted by the invention is as follows: a double-side polishing method is characterized in that the double-side polishing machine is utilized for polishing, during polishing, a workpiece carrying disc drives a workpiece to rotate around the axis of the workpiece carrying disc at a rotating speed, an upper polishing disc and a lower polishing disc clamp the workpiece on the workpiece carrying disc and rotate at another rotating speed, and the rotation of the workpiece carrying disc and the rotation of the lower polishing disc have a speed difference, so that polishing is completed.
The design principle and the beneficial effects of the invention are as follows:
the invention particularly adopts a single workpiece carrying disc which is eccentrically arranged with the lower polishing disc and is larger than the lower polishing disc, and glass is placed in a workpiece placing hole on the workpiece carrying disc; when the polishing machine is used, the upper polishing disk is pressed downwards to press a workpiece between the upper polishing disk and the lower polishing disk, the workpiece carrying disk is driven by the three groups of driving gears on the periphery to do rotary motion (namely, only autorotation), namely, the workpiece is driven to rotate around the center of the workpiece carrying disk, and the upper polishing disk and the lower polishing disk respectively do rotary motion to polish the workpiece. Therefore, the following effects are provided:
1. because the lower polishing disk and the workpiece carrying disk have certain eccentricity, the rotating speeds of the lower polishing disk and the workpiece carrying disk are asynchronous, and the lower polishing disk and the workpiece carrying disk have speed difference, the motion track of the workpiece relative to the lower polishing spare tire is complex, the polishing effect of the polishing device is equivalent to that of polishing equipment such as a planetary wheel in the prior art, and a better workpiece surface type can be obtained; in addition, in the working process, the upper polishing disk and the lower polishing disk can also run at a stepless speed regulation mode, the workpiece carrying disk can also run at a stepless speed regulation mode, and under the condition of adopting the stepless speed regulation mode, namely the speed difference changes constantly, the running track of the workpiece relative to the lower polishing disk can be obtained, so that a better processing effect is obtained; in the prior art, because the gear ring and the sun gear are difficult to be absolutely synchronized, the polishing equipment is extremely easy to be blocked if the polishing equipment is driven by stepless speed regulation, and cannot be suitable for the stepless speed regulation.
2. Because the three identical gears are used for driving the workpiece carrying disc to rotate, the problem that a gear ring and a sun gear are difficult to synchronize in the prior art does not exist, the workpiece carrying disc can be guaranteed to rotate around the axis of the workpiece carrying disc all the time, the workpiece carrying disc and the workpiece can be accurately stopped under the control of a program, the workpiece is taken and placed at the same position every time, and the premise guarantee is provided for the manipulator to automatically take and place the workpiece.
3. The whole structure is simple, the maintenance is convenient, and the cost is lower.

Detailed Description
The invention is further described with reference to the following figures and examples:
example one, see figures 1-5 for a description of:
a double-sided polishing machine comprises an upper polishing disk 2 and a lower polishing disk 3 which are oppositely arranged on a frame 1, wherein the upper polishing disk 2 and the lower polishing disk 3 are coaxially and oppositely arranged up and down, and the processing surfaces of the upper polishing disk 2 and the lower polishing disk 3 are the same or the processing surface of the lower polishing disk 3 is slightly larger than that of the upper polishing disk 2.
Referring to fig. 1, the upper polishing disk 2 and the lower polishing disk 3 can move toward and away from each other. Specifically, a lifting mechanism is usually added to the upper polishing disk 2, and the lifting mechanism drives the upper polishing disk 2 to press down and approach the lower polishing disk 3. The specific lifting mechanism can be an electric cylinder, an oil cylinder or an air cylinder in the prior art.
The upper polishing disk 2 and the lower polishing disk 3 are connected with a rotary driving mechanism to drive the rotary driving mechanism to rotate. The upper polishing disk 2 and the lower polishing disk 3 can be driven by a driving mechanism respectively, and can also be driven by the same set of driving mechanism to move, and the operation is optional.
Referring to fig. 1 and 2, a disc-shaped workpiece carrier plate 4 is disposed between the upper polishing plate 2 and the lower polishing plate 3, and is provided with a workpiece placing hole 41 for placing a workpiece 411. The disc surface of the workpiece carrying disc 4 is larger than that of the lower polishing disc 3, so that the outer edge of the workpiece carrying disc exceeds the outer edge of the lower polishing disc 3, and the outer edge of the workpiece carrying disc 4 is provided with a transmission gear 42 which is meshed with at least three gears 5 to drive the workpiece carrying disc 4 to rotate around the axis of the workpiece carrying disc. Furthermore, the rotation center of the workpiece carrier plate 4 and the rotation center of the lower polishing plate 3 have an eccentric amount X, as shown in fig. 3 and 5, the workpiece carrier plate 4 can be usually directly placed on the lower polishing plate 3, the workpiece 411 can be positioned in the workpiece placing hole 41, the thickness of the workpiece carrier plate 4 is smaller than that of the workpiece 411, and therefore the upper end of the workpiece 411 protrudes out of the surface of the workpiece carrier plate 4. In operation, as shown in figure 5, the upper polishing pad 2 is pressed down on the upper surface of the workpiece 411, i.e. the workpiece 411 is clamped between the upper polishing pad 2 and the lower polishing pad 4.
Because different workpiece thicknesses are different, when a thin sheet is processed, the workpiece carrying disc 4 is thinner than the workpiece, the strength of the workpiece carrying disc 4 is poor, the workpiece carrying disc 4 may droop under the influence of gravity, and the workpiece carrying disc 4 has a tearing risk, so that the outer edge of the workpiece carrying disc 4 is provided with a bearing part 61 and an upper limit part 71 to restrain the workpiece carrying disc 4 and avoid tearing caused by tilting or drooping of the workpiece carrying disc.
Specifically, as shown in fig. 2 and 4, the supporting portion 61 and the upper limiting portion 71 are configured such that an annular tray 6 is fixedly disposed on the outer periphery of the lower polishing platen 3 relative to the frame, and an inner edge of the annular tray 6 extends below an outer edge of the workpiece carrier platen 4 to serve as the supporting portion 61 for supporting the outer edge of the workpiece carrier platen 4. A plurality of pressing plates 7 are uniformly arranged above the outer edge of the workpiece carrying disc 4, the pressing plates 7 are fixed relative to the frame, specifically, the pressing plates 7 are fixed on the annular tray 6 through screws, and the lower surfaces of the pressing plates 7 are used as the upper limiting parts 71 and used for restraining the outer edge of the workpiece carrying disc 4.
The three gears 5 are driven by the same servo motor to synchronously rotate. The present embodiment is exemplified by three gears 5 driving, and in practice, it is also possible to drive more than three gears 5.
In order to further improve the positioning accuracy of the workpiece carrying disc 4 and the workpiece, a set of manual initial positioning mechanism is arranged: at least two positioning holes 43 are formed in the workpiece carrying disc 4, and two positioning tools 8 are arranged corresponding to the two positioning holes 43; the positioning tool 8 is a rod-shaped body, one end of which is provided with a pin hole 81, and the other end of which is provided with a positioning pin part 82 extending downwards; the frame 1 is provided with a cylindrical pin 9 extending upwards, the end part of the positioning tool 8 is sleeved on the cylindrical pin 9 through a pin hole 81, the other end of the positioning tool 8 extends to the upper part of the workpiece carrying disc 4, and a positioning pin part 82 of the positioning tool is correspondingly embedded and matched with the positioning hole 43. The cylindrical pin 9 is disposed on the gear 5 and is disposed coaxially with the gear 5. When the workpiece is initially processed, the two positioning tools 8 are used, the workpiece carrying disc 4 is accurately positioned and calibrated at an initial position, and the positioning tools 8 are taken down before starting.
When the embodiment works, a workpiece 411 (such as mobile phone glass) is placed in the workpiece placing hole 41 on the workpiece carrying disc 4; during processing, the upper polishing disk 2 is pressed downwards, the workpiece 411 is pressed between the upper polishing disk 2 and the lower polishing disk 3, and the upper polishing disk 2 and the lower polishing disk 3 both rotate to polish the workpiece. Because the workpiece carrying disc 4 and the lower polishing disc 3 have a certain eccentric amount X, the relative track of the workpiece carrying disc 4 and the lower polishing disc 3 is complex when the workpiece carrying disc and the lower polishing disc rotate, and particularly under the condition that the workpiece carrying disc 4 adopts stepless speed regulation, the track is changed ceaselessly, and a workpiece surface type with better performance can be processed.
The embodiment has the advantages of simple overall structure, convenient maintenance and lower cost.
Example two, see fig. 6 for a schematic:
a double-sided polishing machine comprises an upper polishing disk 2 and a lower polishing disk 3 which are oppositely arranged on a frame 1, wherein the upper polishing disk 2 and the lower polishing disk 3 are coaxially and oppositely arranged up and down, the processing surfaces of the upper polishing disk 2 and the lower polishing disk 3 are the same, or the processing surface of the lower polishing disk 3 is slightly larger than that of the upper polishing disk 2, and the difference between the first embodiment and the second embodiment is that: the workpiece carrying disc 4 is also provided with a round hole, a matched disc 44 is embedded in the round hole, and the disc 44 is matched with the workpiece carrying disc 4 in a rotating way; the workpiece placement hole 41 is specifically opened in the disk 44. The circular disc 44, the workpiece carrier disc 4 and the lower polishing disc 3 are mutually eccentric. When the work is done, a work piece 411 (such as mobile phone glass) is placed in the work piece placing hole 41 on the work piece carrying disc 4; when the polishing machine is used, the upper polishing disk 2 is pressed downwards, the workpiece 411 is pressed between the upper polishing disk 2 and the lower polishing disk 3, the upper polishing disk 2 and the lower polishing disk 3 both perform rotary motion, the workpiece carrying disk 4 performs rotary motion under the driving of the gear 5, and the disk 44 drives the workpiece on the disk to rotate.
Other embodiments are the same as those in the first embodiment, and are not described herein again.
Example three: a double-side polishing method is implemented by using the double-side polishing machine of the embodiment, during polishing, a workpiece carrier disk drives a workpiece to rotate around the axis of the workpiece carrier disk at one rotation speed, an upper polishing disk and a lower polishing disk clamp the workpiece on the workpiece carrier disk and rotate at the other rotation speed, and the rotation of the workpiece carrier disk and the rotation of the lower polishing disk have a speed difference, so that polishing is completed. The relative track of the workpiece relative to the lower polishing disc 3 is complex, and the polishing effect is good.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
