The cost is low, and the position of the product is positioned by the engraved line on the transparent film and the positioning pin, so that the positioning process is simple and accurate, and the consistency is good, while the movable positioning block is convenient to clamp and has good adaptability, and the product will not shift when the line is scored , High reliability.

As a preference, a pin hole is provided in the center of the plate, and a thread is provided at the bottom of the positioning pin, the positioning pin is fixed with the plate thread, and the positioning pin is movably connected with the plate, and different positioning pins can be replaced according to different products to improve the positioning control. adaptability.

Preferably, the top of the positioning pin is semicircular, and the arc-shaped head can improve the safety and reliability when the center hole of the product is inserted into the positioning pin, and improve the quality of the marking operation of the product.

As a preference, the positioning block consists of two pieces, which are respectively attached to the edges of the two sides of the product. The positioning block is provided with a long groove, and the long groove is provided with a fixing screw. The positioning block is fixed on the plate through the fixing screw, and the positioning block is close to and clamps the product to ensure that there will be no deviation during the marking process, which will cause the marking line to fail, and improve the quality of the product.

The beneficial effects of the utility model are: the manual positioning of the original high-purity alumina ceramic fork products is replaced by the positioning and fixing of the jig, the transparent sheet can be designed and manufactured on site, and the assembly process of the positioning jig is quick and easy. The cost is low, the position of the product is positioned by the engraved line on the transparent film and the positioning pin, so that the positioning process is simple and accurate, and the consistency is good. The movable positioning block is convenient to clamp and has good adaptability, and the product will not be biased when the line is scored. shifting and high reliability.

Detailed ways

The technical solutions of the present utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

Embodiment: A laser marking positioning fixture for high-purity alumina ceramics of this embodiment is used for surface marking operations of high-purity alumina ceramic fork products 1. As shown in Figure 1, the positioning fixture includes a flat plate 2. The transparent sheet 3 and two positioning blocks 4 fixed on the surface of the plate are processed with an M8 pin hole in the center of the plate, and a cylindrical positioning pin 5 is installed in the pin hole, and the top of the positioning pin is half Round shape, the diameter of the positioning pin coincides with the center hole of high-purity alumina ceramic fork products. The multiple positioning lines correspond to different products respectively. There are multiple sets of mounting holes 21 designed on the plate, and long slots 41 are designed on the two positioning blocks. Fixing screws are installed in the long slots. The positioning blocks can be adjusted according to different products. The size is selected from the corresponding mounting hole on the plate and fixed on the plate through fixing screws. At the same time, the positioning block can also accurately abut and clamp the product through the offset of the long groove on the plate.

The assembly process of the positioning fixture:

According to the size of the center hole of the product, select the appropriate positioning pin and tighten it on the plate;

Place the transparent sheet engraved with the positioning line on the surface of the plate and fix it on the plate with self-tapping screws;

According to the size of the product, determine the appropriate mounting hole and connect the positioning block to the plate through the fixing screw to complete the assembly of the positioning fixture;

Product engraving process:
