Description

Automatic centering and positioning device for glass edge grinding machine

Technical Field

The utility model relates to the technical field of auxiliary devices of glass edge grinding machines, in particular to an automatic centering and positioning device of glass edge grinding machines.

Background technique

Glass edge grinding machine, as the name suggests, is a kind of equipment used to process and grind glass. It is mainly used to trim and polish the end edges of glass to make them smooth and bright.

A positioning device is installed at the entrance end of the glass edge grinding machine. Currently, the positioning device is fixed on one side and clamped on the other side. Since roller feed belts are installed on the positioning device and the glass edge grinding machine, one end of the glass is clamped by thrust while the glass moves forward. Therefore, when the glass enters the glass edge grinding machine, the glass will enter toward one end (the centering deviation caused by uneven force on the glass during movement). Therefore, the current positioning device has poor centering accuracy, which can easily lead to an increase in the amount of edge grinding at one end of the glass, resulting in defective products and affecting production efficiency.

In addition, in order to solve the problem of poor centering accuracy of the positioning device for glass, relevant theoretical designs have been proposed in the market, such as the patent document number: CN213531681U, the patent name: A Chinese utility model patent for automatic centering fixture, which specifically discloses: a base, the base is equipped with a workpiece seat, the workpiece seat is used to place the workpiece; a positioning component, the positioning component includes a driving mechanism and two groups of positioning mechanisms, the two groups of positioning mechanisms are respectively located on both sides of the base, the positioning mechanism is provided with a spring piece, a pressure column and a mounting seat, the spring piece and the pressure column are installed at one end of the mounting seat facing the workpiece seat, the spring piece has a pushing end facing the workpiece seat and tilted downward, There are at least two pressure columns, and at least two of the pressure columns are distributed on both sides of the spring sheet. The driving mechanism is used to drive the mounting seats of the two groups of the positioning mechanisms to move synchronously toward the workpiece seat or synchronously away from the workpiece seat; wherein the driving mechanism includes a gear, a rack and a driving cylinder, and there are two racks, and the two racks are meshed and connected to the two sides of the gear. The driving cylinder drives and connects one of the racks, and the mounting seats of the two positioning assemblies are connected to the two racks in a one-to-one correspondence. The driving mechanism also includes a mounting frame, which is mounted and connected to the rack, and the mounting frame is provided with a slot, and the push rod of the driving cylinder is connected to the slot through a connecting piece.

However, the automatic centering fixture designed according to the above theory requires high processing accuracy for each part of its positioning mechanism, and its processing cost is high. Its driving mechanism adopts mechanical gear transmission, and its parts cost is high. In summary, its overall manufacturing cost is high, and it is not suitable for the glass processing field.

Therefore, in summary, the market is in urgent need of a new centering positioning device with high centering positioning accuracy and low manufacturing cost.

3. In summary, the automatic centering and positioning device for a glass edge grinding machine provided by the utility model not only greatly improves the centering and positioning accuracy of the glass, but also has a low manufacturing cost.
