Description

Technical Field

[0001] The invention relates to the field of fixtures, and in particular to a positioning fixture and a positioning method for cutting stone mosaic particles. Background Art

[0002] Stone mosaic art utilizes small pieces of stone, meticulously cut and assembled, to create vibrant, richly patterned artworks with high economic added value. Currently, the production of stone mosaic art relies primarily on manual labor, which is costly and inefficient. Therefore, automated production is imperative. Material standardization is crucial for automated stone mosaic production. Currently, manual laying involves cutting the stone into strips and then using specialized scissors to cut the material as needed. This method produces mosaic particles with uneven cross-sections and varying lengths, making them unsuitable for automated production. Using a wire saw for cutting is a preferred method, but the required stone particles are approximately 4 mm in size, and due to their small size, they are prone to displacement during cutting, resulting in deviations in particle size. Summary of the Invention

[0003] The purpose of the present invention is to achieve high-quality and high-efficiency cutting of stone mosaic particles and solve the problem that displacement is easily generated when cutting with a wire saw, resulting in large dimensional deviation.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a positioning fixture for cutting stone mosaic particles, comprising: a support plate, a first fixed clamping block, a first movable clamping block, a second fixed clamping block, a second movable clamping block, a first screw rod, a second screw rod and a base; the first fixed clamping block and the first movable clamping block are a group correspondingly installed on the side surface of the support plate to form an X-direction clamping area, and the second fixed clamping block and the second movable clamping block are a group correspondingly installed on the other side surface of the support plate to form a Y-direction clamping area; the first fixed clamping block and the second fixed clamping block are fixed to one side of the support plate by bolts, and the first movable clamping block and the second movable clamping block are connected to the support plate by a screw rod, and the workpiece is clamped by rotating the screw rod; one end of the screw rod is fixed to the support plate, and the other end is connected to the movable clamping block; the base is connected to the support plate and fixed by bolts.

[0005] Preferably, a conical support structure is provided on the top of the support plate, and two positioning holes and a hole connected to the screw rod are provided on the side where the support plate is connected to the movable clamping block.

[0006] Preferably, the first and second fixed clamping blocks are provided with tooth-shaped gaps to facilitate the wire saw to cut the material.

[0007] Preferably, the first and second movable clamping blocks are provided with tooth-shaped gaps, a screw nut connecting hole is provided in the middle of the clamping block for connecting the screw nut, and positioning shafts are provided on both sides of the screw connecting hole.

[0008] Preferably, one end of the screw nut is fixed in the screw nut connecting hole of the movable clamping block, and a threaded hole is provided on the side of the other end for connecting a fixing bolt.

[0009] The present invention has the following beneficial effects: The fixture designed in the present invention can solve the problem of large dimensional deviations caused by displacement when cutting stone particles with a wire saw. It achieves high-quality and efficient cutting of stone mosaic particles. By providing tooth-shaped gaps on the clamping block, the present invention achieves workpiece positioning without hindering wire saw cutting. By providing a conical support structure on the top of the base plate, the present invention achieves workpiece positioning while preventing overcutting caused by wire bow during wire saw cutting, thereby reducing damage to the fixture and protecting it.
