Description

Technical Field

[0001] The utility model relates to the technical field of CNC cutting processing, in particular to a CNC cutting processing fixture capable of flipping and adjusting the angle. Background Art

[0002] CNC (CNC machine tool) is the abbreviation of computer numerical control machine tool, which is an automated machine tool controlled by a program. Metal workpiece processing needs to be carried out on a CNC machine tool, and corresponding punching, trimming and other processes need to be performed. The workpiece needs to be clamped during processing, so the fixture components of the CNC machine tool are required.

[0003] Most of the clamps currently in use cannot be automatically raised, lowered or flipped, and are not convenient for clamping workpieces.

[0004] After searching, the existing patent [CN 216503636 U] discloses a CNC clamp for processing metal products, including a workpiece clamping platform, the upper surface of the workpiece clamping platform is symmetrically fixedly connected to two T-shaped positioning frames, and a reversible clamp body is rotatably connected between the two T-shaped positioning frames, and a rotating rod extending to the outside of the T-shaped positioning frame is provided on one side of the reversible clamp body, and a reversing drive mechanism for driving the reversible clamp body to rotate is installed on one side of the upper surface of the workpiece clamping platform located on the T-shaped positioning frame. The utility model is provided with a reversible clamp, which can quickly clamp metal workpieces when used, and can adjust the reversing angle of the metal workpiece according to needs, and can perform double-sided processing, thereby reducing the intermediate disassembly and fixing links, improving the efficiency of the device, and solving the problem that the current device cannot perform double-sided processing of metal workpieces. This CNC clamp solves the problem of not being able to flip;

[0005] Although the above utility model patent solves the problem of being unable to flip, most of the clamps currently in use cannot be automatically lifted and flipped. During use, some workpieces that need to be clamped are heavy and inconvenient to carry. If they cannot be lifted, flipped, or flipped, it may be difficult to carry the workpieces, making the device more laborious and time-consuming to use, reducing the working efficiency of the device, and further affecting the subsequent processing efficiency. It is also inconvenient to clamp the workpiece. During use, the clamping force on the workpiece is weak, which may result in poor clamping effect, which may cause the workpiece to fall, and the difficulty in operating the clamping mechanism may require professionals to clamp, making the device more difficult to operate. Utility Model Content

[0006] The utility model aims to provide a CNC cutting fixture with a flippable and adjustable angle to solve the problems in the prior art.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC cutting fixture with a flippable angle adjustment, comprising a workbench, a lifting and flipping mechanism is provided on one side of the workbench, and the lifting and flipping mechanism comprises a support plate;

[0008] A support plate is fixedly connected to one side of the workbench, a first electric push rod is fixedly connected to the top of the support plate, and a fixing frame is fixedly connected to the top of the first electric push rod.

Through the connection between the second electric push rod and the fixed block, the second electric push rod can drive the fixed block to move.

[0012] As a preferred technical solution, a rack is provided at the bottom of the fixed block, a gear is movably connected inside the rack, and a flip plate is fixedly connected to one end of the rotating rod. The rack can drive the gear to rotate through the connection between the gear and the rack.
