Clamping devices used for carving machining

Abstract

The invention discloses clamping devices used for carving machining. The clamping devices each comprise a supporting seat. The supporting seats are mounted on a worktable. Fixed bottom plates and vertical plates are arranged on the upper end faces of the supporting seats. Adjusting sliding plates are connected with the vertical plates and slidably connected with movable caliper bodies. The movable caliper bodies are fixedly connected with adjusting pressing plates. Pushing plates are arranged above the adjusting pressing plates. Elastic elements are arranged between the adjusting pressing plates and the pushing plates. Pneumatic devices are fixedly mounted on the upper portions of the vertical plates and fixedly connected with the pushing plates. Electromagnets and gasket sucking discs are arranged on the fixed bottom plates and the adjusting pressing plates correspondingly. According to the clamping devices used for carving machining, by arranging the pneumatic devices, workpieces can be automatically clamped, the clamping force is large, and the labor intensity is large. By arranging the electromagnets and gasket sucking discs, the situation that the workpieces do not slide is guaranteed, the clamping force is further increased, and fixity is better. The elastic elements are arranged between the fixed bottom plates and the adjusting pressing plates, so that adjusting of the clamping force is facilitated, and damage to the workpieces is avoided.

Description

technical field [0001] The invention relates to the technical field of engraving machines, in particular to a clamping device for engraving. Background technique [0002] Engraving machine is a commonly used engraving equipment, used to engrave various sculptures and models. With people's understanding and mastery of engraving machines, the application scope and application level will gradually increase, such as advertising industry, seal industry, craft gift industry, art model industry, wood processing industry, mold industry and so on. Machinable materials include acrylic, two-color board, PVC, ABS board, stone, imitation stone, metal, aluminum-plastic board and other materials. The application of engraving machines in the advertising industry is mainly: engraving and cutting various types of signs, coordinate signs, marble, copper, fonts, fonts, various signs, trademarks and other metal materials. The engraving machine is one of the core equipment for the rapid develop...

AI Technical Summary

Problems solved by technology

The engraving machine is one of the core equipment for the rapid development of modern industry, and it is widely used. The existing engraving machine is generally equipped with a zigzag working surface on the workbench, so as to prevent the workpiece from slipping and avoid engraving deviation, which may cause Defective products, but the clamping device of the prior art is obviously defective, which is easy to cause damage to the surface of the processed workpiece, or even deformation, and the processed surface is generally difficult to repair after wear, the contact area is small, the friction is small, it is easy to slide, and it is not stable. The force of the existing clamping device after clamping is difficult to adjust, without further increasing the clamping force, it cannot be installed flexibly, resulting in greatly reduced machining accuracy and assembly accuracy

In addition, the existing clamping devices are generally fixed on the workbench, and the position cannot be flexibly adjusted according to the size and thickness of the plate, and continuous position adjustment cannot be realized. When clamping the plate, the staff generally needs to place the plate on the work surface Carry out clamping installation, after the processing is completed, another plate is taken for clamping installation, and the cycle repeats, the labor intensity of the staff is very high, and the production efficiency is also very low. Low, unable to adapt to the height of the staff to work, if things go on like this, the staff will have lumbar muscle strain, which will damage the health of the staff
