detailed description

As shown in Figure 1, a glass cutting machine has a base 1, the base 1 is symmetrically equipped with a left horizontal screw nut transmission mechanism 3 and a right horizontal screw nut transmission mechanism 12, and the left horizontal screw nut transmission mechanism 3 is equipped with The left cutting wheel 4 is powered by the left stepper motor 2, the right horizontal screw nut transmission mechanism 12 is equipped with the right cutting wheel 11 and powered by the right stepper motor 13, and a vertical screw nut is also installed on the base 1 Transmission mechanism 5, vertical screw nut transmission mechanism 5 is powered by upper stepping motor 7. A mounting plate 8 is installed on the leading screw of the vertical lead screw nut drive mechanism 5, and a rotary main shaft 6 is vertically installed on the mounting plate 8, and the rotary main shaft 6 is powered by a motor 9, and a clamp 10 is installed at the bottom of the rotary main shaft 6. In order to ensure the stability and transmission accuracy of the screw during rotation, the left and right horizontal screw nut transmission mechanisms are symmetrically installed on both sides of the center of the base, and the height of the screw axis of the left and right horizontal screw nut transmission mechanisms remains Consistent; the center of the rotary spindle 6 coincides with the center of the base 1.

In order to achieve a smooth cutting of the glass without shattering, a double-sided simultaneous cutting method is adopted. In order to ensure the transmission accuracy, the screw nut transmission mode is adopted; in order to ensure the synchronous feeding of the left and right cutting tools, the left and right horizontal screw nut transmission mechanisms are installed symmetrically with the same height from front to back. Due to processing errors, the cutting tools may have different heights, and the left and right cutting wheels are installed in a height-adjustable manner to ensure that the two cutting wheels cut on the same plane. The vertical rotary spindle is driven by the vertical screw nut to move up and down to realize the adjustment of the workpiece entering and exiting the cutting area and the cutting position.

A high-speed DC motor is used to drive the cutting wheel to rotate at high speed for cutting. After cutting, the left and right stepping motors reverse the cutting wheel to retract the knife, and the rotary spindle rises to replace the workpiece for the next processing cycle. During the cutting process, the rotary spindle rotates at a slow speed, which needs to overcome the cutting resistance, and is driven by a stepping motor that can provide a large torque.

In order to realize automatic control, the left stepper motor 2, the right stepper motor 13, the upper stepper motor 7, the motor 9 and the high-speed DC motor are connected to a PLC, and the opening or closing of each motor is controlled by the PLC.

In order to prevent glass shards from flying out and hurting people, other mechanisms of the utility model are set in the transparent glass protective cover except the PLC. The transparent glass protective cover is equipped with a position sensor, which is connected to the PLC. The transparent glass protective cover is not closed. In this case, the equipment cannot operate.

Working process: The operator clamps the semi-finished glass cup to be processed on the fixture 10 of the rotary spindle 6, closes the transparent glass protective cover, presses the start button, and the rotary spindle is driven by the vertical screw nut transmission mechanism to drop to the processing height. The DC motor drives the left and right cutting wheels to rotate at high speed, and at the same time the left and right stepping motors rotate to drive the nuts in the left and right horizontal screw nut transmission mechanisms to realize synchronous feeding and cutting of the left and right cutting wheels. During the cutting process, the rotating spindle is slow Rotate at a high speed until the excess glass is completely cut off and falls off, the left and right stepping motors reverse, and the left and right cutting wheels return to their original positions; the transparent glass protection is opened, the cover operator releases the clamp 10, takes off the cut glass, and replaces Load a semi-finished glass cup to be processed, and continue the next processing cycle. When the transparent glass protective cover is not closed, the controller cannot receive the position signal of the protective cover, and all motors are locked to prevent the broken glass from flying out and hurting the operator.

Grinding the cut can be achieved by replacing the cutting wheel with a grinding wheel. Subsequent grinding, chamfering and polishing can get the finished glass.
