Description

Technical Field

[0001] The invention belongs to the field of positioning and clamping, and in particular relates to a clamping and positioning device for lettering. Background Art

[0002] Before the electrical installation of a cube product, the product number must be engraved on the surface of the product with a laser engraving machine. Because the engraving position of the product is a symmetrical rectangular plane, it is not easy to distinguish, and the process has strict requirements on the engraving position and size. If the engraving is wrong or crooked, it must be returned to the previous process for re-polishing and re-painting, which is time-consuming and labor-intensive and affects the production progress. In order to accurately and quickly laser engrave the product, a laser engraving clamping and positioning device is designed and manufactured. Summary of the invention

[0003] The purpose of the present invention is to provide a clamping and positioning device for engraving in order to solve the problems of inaccurate engraving position and complicated engraving process when engraving cubic products by traditional process.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] The clamping and positioning device for engraving of the present invention comprises a base with a flat upper surface, a vertical limit plate fixed on the right side of the base, a horizontal guide rail arranged on the left side of the base and perpendicular to the vertical limit plate, and a vertical clamping plate whose track is connected to the horizontal guide rail and is always parallel to the vertical limit plate;

[0006] The base is provided with a positioning hole matching the workbench of the laser engraving machine;

[0007] A positioning column matching the side hole of the product to be engraved is provided on the left side surface of the vertical limit plate;

[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 includes a bolt, a nut and a washer; a T-shaped head is processed at the lower end of the bolt, and the horizontal guide rail is a T-shaped slot matching the lower end of the bolt. The lower end of the bolt is inserted into the T-shaped slot of the horizontal guide rail, and the upper end of the bolt passes through the connecting hole of the vertical clamping plate and is connected to a nut and a washer. By locking the nut, the vertical clamping plate is fixed on the horizontal guide rail.

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

[0011] Working process

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

[0013] 2. Place the product to be engraved on the base of the device, and plug the side hole of the product to be engraved into the positioning column on the left side of the vertical limit plate, so that the right side of the product to be engraved is positioned with the vertical limit plate;

[0014] 3. Push the vertical clamp to move to the right. When the vertical clamp is close to the left side of the product to be engraved, the vertical clamp is fixed on the horizontal guide rail through the locking mechanism to achieve clamping and positioning of the product to be engraved.

[0015] 4. Start the laser engraving machine and start laser engraving the product to be engraved.

[0016] Beneficial effects:

[0017] When a specific product is laser engraved using the clamping and positioning device of the present invention, the engraving position is accurate, and the product will not be skewed due to accidental contact during the engraving process. Due to the presence of the positioning column on the vertical limit plate, the product can only be positioned in a specific direction on the device. At the same time, the device can accurately position the product, avoiding the phenomenon of repeated positioning for each product engraved, ensuring product quality while improving production efficiency. The design concept of the device can be applied to the positioning and clamping of other similar products. BRIEF DESCRIPTION OF THE DRAWINGS
