Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a fixing device for stone processing. Background Art

[0002] With the development of the building decoration industry, stone as a high-end building decoration material is becoming more and more popular. There are many types of stone, such as marble, granite, limestone, etc. Stone is a natural or artificial building material, usually used for building decoration, carving and building structure. Different stones have different physical and chemical properties, so they have different advantages and limitations in different application scenarios.

[0003] In the stone processing process, in order to achieve the purpose of precise processing, it is necessary to reduce vibration and displacement, which often requires the use of fixing devices to fix the stone. The fixing devices currently used in stone processing are generally composed of limit plates, splints and cylinders. The cylinder will drive the splint to press the stone against the limit plate, thereby fixing the stone. However, this method can only fix both sides of the stone, the fixing effect is not good, and there is a lack of positioning function. When the stone is placed on the fixing device, it is necessary to manually fine-tune the position again, which is extremely cumbersome. Moreover, after the previous piece of stone is processed, multiple staff members are required to work together to move the new stone to the surface of the fixing device for fixing. In view of the heavy stone, this method increases the labor intensity of the workers, is time-consuming and labor-intensive, and reduces work efficiency.

[0004] Therefore, a fixing device for stone processing is proposed to solve the above problems. Utility Model Content
