Problems solved by technology

[0002] In the prior art, numerically controlled machine tools (CNC) are usually used to chamfer workpieces made of hard and brittle materials such as glass, sapphire, silicon carbide, and zirconia. The grinding head is used to chamfer the edge of the workpiece. This processing method requires the workpiece to be processed to have a larger surface so that it can be adsorbed on the working platform. It is very suitable for processing larger-sized workpieces, but it is suitable for processing small-sized round hard and brittle When the material sheet (D<30mm), there are the following processing difficulties: (1) If the power of the vacuum pump is small, and the adsorption surface of the small-sized round hard and brittle material sheet is small, it is very easy to cause flying pieces due to insufficient adsorption force. , slivers, crashing the grinding head and other accidents
(2) If you replace a vacuum pump with a higher power, when processing a workpiece with a large area and a small thickness, it will cause slivers due to too much adsorption force. High, inconvenient to use
(3) In the prior art, it takes about 15 to 20 seconds for a CNC machine tool to process a piece of small workpiece, and the efficiency is low
(4) The chamfering angle of the CNC machine tool has high requirements on the level of the operator, and the operation of the machine tool by an employee with less experience will easily cause the workpiece to be scrapped and increase the cost

Embodiment Construction

[0035] For the convenience of description, use figure 1 Chinese characters refer to the definitions of "front", "rear", "left", and "right" in the examples, with sapphire as a representative instead of hard and brittle materials.

[0036] Such as Figure 1 ~ Figure 7 As shown, a small-size round hard and brittle material sheet beveling device includes a bracket 1, a water tank 2, an sand bowl 3, a rotating motor 4, and a round sapphire sheet (ie, a round hard and brittle material sheet). At the bottom of the emery bowl 3, an indenter 5 that makes the sapphire sheet relatively rotate relative to the emery bowl 3, and an eccentric pressurizing system 6 that rotates eccentrically to apply pressure to the indenter 5 to ensure uniform beveling of the sapphire sheet.

[0037] The top surface of the support 1 is stepped, the water tank 2 is arranged on the lower step of the support 1, the rotating motor 4 is arranged at the bottom of the water tank 2, and the sand bowl 3 can be rotated at...

Abstract

The invention discloses edge chamfering equipment for small-size round hard and brittle material sheets and an edge chamfering method of the edge chamfering equipment. The equipment comprises a support, a water tank, sand bowls, rotating motors for driving the sand bowls to rotate, pressing heads as well as eccentric pressurizing systems capable of rotationally applying pressure to the pressing heads to guarantee uniform edge chamfering of the round hard and brittle material sheets; the top surface of the support is step-shaped; the water tank is arranged on a lower step of the support; the rotating motors are arranged at the bottom of the water tank; the inner walls of the sand bowls is in the funnel shapes with the upper parts being conical walls; the lower parts of the pressing heads are circular truncated cones pressed at the bottoms of the conical walls in a fit manner; inserting rod holes are formed downwards in the centers of the top surfaces of the pressing heads; each eccentric pressurizing system comprises an inserting rod; the lower end of each inserting rod is a rotatable inserting rod round head; each eccentric pressurizing system further comprises an eccentric pressurizing component capable of driving the corresponding inserting rod to rotate around the corresponding inserting rod round head by using the inserting rod round head as the apex to pressurize the corresponding pressing head. Uniform edge chamfering of the round hard and brittle material sheets is guaranteed, sheet cracking and sheet flying are reduced, the machining efficiency is obviously improved, and the operation difficulty is low.

Description

Technical field [0001] The invention belongs to the field of hard and brittle material processing, in particular to a chamfering device and a chamfering method for small round hard and brittle material pieces. Background technique [0002] In the prior art, numerically controlled machine tools (CNC) are usually used to chamfer workpieces made of hard and brittle materials such as glass, sapphire, silicon carbide, zirconia, etc. Specifically, the workpiece is sucked onto the work platform by drawing a vacuum, and then rotated. The grinding head is used to chamfer the edge of the workpiece. This processing method requires the workpiece to be processed to have a larger surface so that it can be adsorbed on the work platform. It is very suitable for processing larger-sized workpieces, but it is hard and brittle when processing small-sized rounds. Material piece (D <30mm), but there are the following processing difficulties: (1) If the power of the vacuum pump is small, and the sma...
