technical field

The utility model relates to a processing device, in particular to a processing device for processing chamfered surfaces at the two peripheral edges of a circular glass sheet.

Background technique

For some circular glass sheets, sometimes it is necessary to process the sharp peripheral edges to form smooth chamfered surfaces at the peripheral edges of the circular glass sheets, so as to facilitate the assembly and circulation of these glass sheets. Under existing circumstances, the processing of chamfering these circular glass sheets is carried out by using a grinding wheel that rotates. The grinding wheel is cylindrical, and its outer peripheral surface is the main grinding surface for grinding. During the chamfering process, the grinding wheel rotates itself driven by the power mechanism, and the circular glass sheet is held by the clamping tool or human hands, and its peripheral edge is against the main grinding surface of the grinding wheel, and rotates at a certain speed. Through the grinding of the main grinding surface of the grinding wheel, a chamfering surface is processed at the peripheral edge of one side of the glass sheet. For the processing of the chamfered surface at the periphery of the other side of the glass sheet, the angle of the glass sheet needs to be adjusted, and the above-mentioned operation steps need to be repeated. This processing method is cumbersome to operate, and the operation efficiency is slow. During the operation, the glass surface is easily damaged, and the consistency between the two chamfered surfaces is not easy to control, which will affect the quality of the finished glass sheet.

Both sides; said power mechanism is a circular power mechanism, driven by the circular power mechanism, the grinding wheel has both self-rotation motion and revolution motion along the periphery of the circular glass sheet. After the circular glass sheet is positioned and fixed by the fixing device, the grinding wheel is driven by the power mechanism to revolve around the circular glass sheet, and at the same time, the grinding wheel itself also rotates. During the working process, the grinding wheel always abuts against the outer peripheral edge of the circular glass sheet. The chamfering grinding surface provided on the grinding wheel is processed with the chamfering surface at the edge of the glass sheet through grinding with the peripheral edge of the glass sheet. The main grinding surface on the grinding wheel can correct the size of the outer peripheral surface of some irregular circular glass sheets, so that the accuracy of the outer peripheral size of the glass sheet can be improved.

The positioning structure includes the positioning backer and the support, and has a simple structure. The end of the support rests against the outer surface of the suction cup, and the length of the support corresponds to the radius length of a circular glass sheet of a certain specification. After the support abuts against the outer surface of the suction cup, when placing the glass sheet on the suction cup, as long as the two inner surfaces of the positioning backer are in line contact with two positions on the outer peripheral surface of the circular glass sheet, at this time, the circular glass sheet The circle center of the sheet can basically coincide with the center position of the end face of the suction cup, and the center position positioning repeatability is high when loading and unloading the glass sheet.

As a preference, the suction cup is provided with a positioning screw for contacting one end of the positioning backer. The provided positioning screw contacts one end of the positioning backer so that when the end of the support contacts the outer peripheral surface of the suction cup, rapid, accurate and repeatable positioning of the positioning backer can be realized.

Preferably, the positioning back has a backing adjustment block, and the backing adjustment block is movably connected to the positioning backing by adjusting screws, and the backing adjustment block is used to contact the side of the glass sheet. By adjusting the position of the backing adjustment block on the positioning backing, the positioning backing can adapt to the positioning requirements of circular glass sheets with different diameters and specifications.

Compared with the prior art, the utility model has the beneficial effects:

Since the outer peripheral surface of the grinding wheel is provided with an annular concave groove, the grinding wheel can process two chamfering surfaces at the periphery of the circular glass sheet at one time during operation, and the chamfering grinding surfaces on the side of the concave groove are symmetrically arranged on the On both sides of the main grinding surface, the two chamfers on the glass sheet have good consistency, and the quality of the processed round glass sheet can be guaranteed.

Because the grinding wheel can revolve around the outer peripheral surface of the circular glass sheet driven by the power mechanism, the main grinding surface of the grinding wheel can correct the irregular outer peripheral surface size of the circular glass sheet, thereby improving the peripheral dimension accuracy of the circular glass sheet.

Due to the adoption of a flat vacuum adsorption device, the loading and unloading of glass sheets is fast, and the loading and unloading of large-size glass sheets is facilitated.

Due to the adoption of a flat vacuum adsorption device, the degree of damage to the surface of the glass sheet during processing is significantly reduced.
