Description

Automatic beveling machine

technical field

The utility model relates to a glass processing machine, in particular to a high-precision automatic beveling machine which does not need to be held by human hands.

Background technique

Glass is an essential material in daily life, industrial production, scientific research and military applications. After the glass product is processed in the previous process, a right-angle edge is formed on its surface and side wall. This right-angle edge is very sharp and easy to cut At the same time, the glass itself is very brittle and prone to chipping. In order to protect the edge of the glass and reduce its sharpness, it is necessary to use a chamfering machine to grind the right angle into an obtuse angle. The traditional edge chamfering machine is generally completed by hand with auxiliary tools. The specific method is: use a hand-held glass, place the chamfering part on the grinding wheel of the auxiliary tool, and press it by hand for grinding. The disadvantage of this method is that it is not easy to control, and the product is prone to chipping, corrugation and other defective products; it is only suitable for ordinary flat glass, and it is not easy to hold long, large-size products and products less than 6mm; the beveling accuracy is not enough; Adjusting the machine is a waste of time and low work efficiency.

In order to process glass with different inclinations and to facilitate the replacement of grinding wheels with different inclinations, the grinding wheel is fixed on the top of the grinding wheel main shaft through the grinding wheel cover.

There is a pressure sensor electrically connected to the control unit at the position where the top wheel is close to the grinding wheel in contact with the glass edge; when the pressure sensor has been under pressure for a long time (after the workpiece glass has rotated once), all the edges of the glass will After all the tipping is completed, the control unit stops the work of the machine.

In a preferred manner, the drive of the workpiece drive motor and the workpiece spindle is driven by a belt with two pulleys.

In order to make the workpiece glass gently contact the grinding wheel, a buffer device is connected between the workpiece bushing and the frame.

More specifically, the buffer device is a compression spring, a pneumatic cylinder or a hydraulic cylinder.

In order to directly observe the working state of the machine, a display screen is also electrically connected to the control main board.

The control main board is preferably a single-chip microcomputer, PLC or industrial computer.

The utility model has the advantages of:

1) It has a wide range of applications and is suitable for glass of various shapes;

2) No profiling is required;

3) The buffer feed speed can be adjusted freely when starting to avoid hitting the grinding wheel;

4) The equipment has good stability and performance, and there is no need to adjust the machine frequently;

5) The grinding wheel has a long service life;

6) It is convenient to adjust the machine and easy to maintain the equipment;

7) The operation is simple, the product size is stable, the change is small, and the precision is high;

8) Automatic control, it can stop automatically after the edge is finished, the time and speed of the edge can be adjusted freely, the efficiency is high, and one person can operate several machines at the same time.
