Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a fixture platform for numerical control machine tools. Background Art

[0002] As we all know, CNC machine tools, also known as digitally controlled machine tools, are automated machine tools equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and represent them with coded numbers. The information is input into the CNC device through an information carrier, and after calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing. CNC machine tools can better solve the problems of complex, precise, small-batch, and multi-variety parts processing. When CNC machine tools process parts, they will clamp them with fixtures to facilitate their processing.

[0003] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0004] Although the above technical solution solves the problem of fixing multiple parts at the same time, in the above technical solution, the connecting plate is pushed to move by the double-axis cylinder, and then the movable plate is driven to move in conjunction with the rotating shaft and the pulley, and the movable plate is reset by the elastic potential energy of the reset spring to adapt to parts of different sizes. However, the parts will generate certain vibrations during processing. Although a single-axis cylinder is used to clamp the parts in the above document, the vibrations generated by the parts during processing may drive the reset spring to resonate, thereby affecting the accuracy of the part processing. In order to solve the above problems, a CNC machine tool fixture platform is needed. Utility Model Content

One or more placement grooves 18 are provided on the sliding plate 7 for accommodating and supporting the fixed component.

[0050] Then, see Figure 2 In this embodiment, the second slide grooves 19 in the fixing assembly are respectively opened on both sides of the sliding plate 7, and each second slide groove 19 is communicated with the placement groove 18, each second slider 8 is slidably connected to the inner wall of the corresponding second slide groove 19, each fixed block 9 is slidably connected to the inner wall of the placement groove 18, and each fixed block 9 is fixedly connected to the corresponding second slider 8, the auxiliary assembly is installed on the carrying plate 4, and is used to assist the movement of the fixed block 9, and each rubber block 10 is fixedly connected to the corresponding fixed block 9.

The second rotating rod 15 rotates to drive the connecting block 14 to move. The connecting block 14 moves to drive the sliding plate 7 to move. The sliding plate 7 moves to drive the first slider 6 to slide in the first slide groove 17. At the same time, the sliding plate 7 moves to drive the fixed block 9 to move. The fixed block 9 moves to drive the second slider 8 to slide in the second slide groove 19. At the same time, the fixed block 9 moves to drive the sliding column 11 to move. The sliding column 11 slides in the inclined slide groove 16 to drive the fixed block 9 to move, so that the rubber block 10 contacts the workpiece, completing the fixation of the workpiece. It can not only fix parts of different sizes, but also cooperate with the rubber block 10 to well reduce the vibration generated during workpiece processing, and will not cause damage to the workpiece due to excessive clamping.
