[0008] The vertical clamping plate is connected to the horizontal guide rail through a locking mechanism, and the locking mechanism fixes the vertical clamping plate at any position on the horizontal guide rail.

[0009] The locking mechanism comprises a bolt, a nut and a washer, the lower end of the bolt is provided with a T-shaped head, the horizontal guide rail is a T-shaped groove matched with the lower end of the bolt, the lower end of the bolt is inserted into the T-shaped groove of the horizontal guide rail, and the upper end of the bolt is connected to the nut and the washer after penetrating through the connecting hole of the vertical clamping plate, so that the vertical clamping plate is fixed on the horizontal guide rail by locking the nut.

[0010] The vertical limiting plate and the base are connected through a rib plate.

[0011] WORKING PROCESS

[0012] 1. The base of the positioning and clamping device is fixed on the laser engraving machine workbench through the positioning hole.

[0013] 2. The product to be engraved is placed on the device base, and the side hole of the product to be engraved is inserted with the positioning column on the left side of the vertical limiting plate, so that the right side of the product to be engraved is positioned with the vertical limiting plate.

[0014] 3. Push the vertical clamping plate to the right side, and when the vertical clamping plate is in close contact with the left side of the product to be engraved, the vertical clamping plate is fixed on the horizontal guide rail through the locking mechanism, realizing the clamping and positioning of the product to be engraved.

[0015] 4. Start the laser engraving machine, and the laser engraving of the product to be engraved can be started.

[0016] Advantages:

[0017] Compared with directly placing the product on the workbench for direct engraving, when the device is used for laser engraving of a certain product, the engraving position is accurate, and the product will not be mis-touched during the engraving process. The product can only be positioned in a specific direction on the device due to the presence of the positioning column on the vertical limiting plate, and the device can accurately position the product, avoiding the need to repeatedly position each product, ensuring product quality and improving production efficiency. The design idea of the device can be applied to the positioning and clamping of other similar products. BRIEF DESCRIPTION OF DRAWINGS
