[0002] Gluing is the act of using glue or other adhesives to bond two or more objects together. During the product processing, the workpieces need to be connected through a glue machine. When the glue machine is working, a positioning auxiliary clamping device is used. This device is a device or tool for fixing and clamping the bonded objects during the gluing process. It ensures that the bonded objects maintain a stable position and pressure before the glue dries, so as to ensure that the glue can effectively bond them together, improving work efficiency and bonding quality.

A second slide groove is opened on the top of the base plate, and a third threaded rod is rotatably installed on the front and rear inner walls of the second slide groove. The clamping mechanism of the glue spraying machine limits the position of its glass plate by setting a movable tooling fixture, so that when the device is performing the glue spraying operation, the glass plate will not be shifted in position due to the movement state of the glue spraying machine. At the same time, a rubber pad is provided on the clamping plate of the tooling fixture, which effectively avoids the glass from being cracked or scratched due to the rigid contact between the clamping plate and the glass, thereby ensuring the quality of the glass plate and improving the practicability of the device to a certain extent.

Secondly, the clamping block of the clamping device is easy to wear, and the traditional thread replacement operation is time-consuming. The threads are prone to rust after long-term use, and there are certain shortcomings in use. Utility Model Content
