Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool fixture technology, and in particular to a CNC machine tool fixture with a flipping function. Background Technology

[0002] A CNC machine tool is an automated machine tool whose machining process is controlled by computer-programmed instructions. It utilizes pre-programmed digital instructions to precisely control the tool's movement trajectory, spindle speed, feed rate, and auxiliary operations, achieving high-precision, high-efficiency, and high-flexibility automated machining of materials such as metals and plastics. It can perform precision manufacturing of various complex-shaped parts, including turning, milling, drilling, boring, and grinding, and is a core piece of equipment in modern manufacturing. During the use of CNC machine tools, fixtures are typically used to clamp the workpiece.

[0003] When using a fixture to clamp a workpiece, it is usually done by two sets of electric push rods. Sometimes, different sides of the workpiece need to be processed, which usually requires flipping the workpiece. However, existing fixtures can usually only clamp the same side of the workpiece and cannot change the clamping surface. This means that when the clamping surface needs to be processed later, the position of the workpiece needs to be manually adjusted, which is not conducive to the use of the fixture.

[0021] In use: When using this CNC machine tool fixture with a flipping function, the workpiece is placed on top of the placement table 32. The second electric push rod 31 drives the placement table 32 to rise, making the workpiece level with the clamping plate 24. The two sets of first electric push rods 18 drive the two sets of push plates 19 to move towards each other. The push plates 19 drive the two sets of mounting blocks 20 to move towards each other.

The second gear 17 drives the rotating disk 13 to rotate, which in turn drives the first electric push rod 18 to rotate. The first electric push rod 18 drives the push plate 19 to rotate, which in turn flips the workpiece. After processing, the second electric push rod 31 raises the placement table 32, placing the workpiece on top of it. The first electric push rod 18 then drives the clamping plate 24 to release the workpiece. The first motor 7 drives the first rotating rod 8 to rotate, which in turn drives the first gear 9 to rotate. The first gear 9 drives the first rack 5 to rotate, which in turn drives the rotating ring 4 to rotate. The rotating ring 4 drives the support plate 10 to rotate, which in turn drives the clamping plate 24 to rotate. This allows adjustment of the clamping plate 24's position, facilitating clamping of the workpiece at different locations and enabling processing of the clamping surface. By pulling the sliding column 27, the sliding plate 29 is moved. The sliding plate 29 moves the mounting column 30 away from the inner wall of the mounting groove 23, so that the clamping plate 24 can be removed. Then, the positioning block 22 on one side of the clamping plate 24 of different sizes is inserted into the inner wall of the positioning groove 21. The spring 28 resets and moves the sliding plate 29. The sliding plate 29 moves the mounting column 30 into the inner wall of the mounting groove 23, so that the clamping plate 24 can be replaced. This achieves the purpose of facilitating clamping of workpieces at different positions and facilitating the replacement of clamping plates 24. The structure is simple and easy to use.
