Description

Technical Field

[0001] The utility model relates to the technical field of numerical control, in particular to a clamping device for numerical control five-axis machine tool processing. Background Art

[0002] The five-axis linkage CNC machine tool is a machine tool with high technological content, high precision, and is specially used for processing complex surfaces. This machine tool system has a significant influence on a country's aviation, aerospace, military, scientific research, precision machinery, high-precision medical equipment and other industries.

[0003] During the use of five-axis machine tools, the workpiece needs to be clamped and fixed on the clamping tool. Five-axis machine tools usually process some special-shaped parts and some relatively tight parts. In actual use, the workpiece often needs to be processed twice or multiple times. However, during the second processing and cutting, the shape of the workpiece has changed after the first processing. Most of them are special-shaped parts. At this time, the single two-sided clamping may become loose, causing the workpiece to shake and move, etc., which brings unnecessary trouble to subsequent processing.

[0004] In view of the existing problems, it is necessary to provide a clamping device for CNC five-axis machine tool processing that can clamp multiple sides of a workpiece. Utility Model Content

[0005] In order to overcome the disadvantage of unstable clamping of two sides during secondary processing, the utility model provides a clamping device for CNC five-axis machine tool processing.

[0006] The technical solution of the utility model is: a clamping device for CNC five-axis machine tool processing, comprising a frame, a first bidirectional screw and a clamping plate, the frame is rotatably connected with the first bidirectional screw, the first bidirectional screw is symmetrically slidably connected with the clamping plate, and also comprises a mounting plate, a guide rod, a second bidirectional screw, a sliding plate, a connecting frame, a fixed rod and an extension plate, the mounting plates are symmetrically installed on the frame, the guide rods are installed on the two mounting plates on the left, the second bidirectional screws are threadedly connected on the two mounting plates on the right, the second bidirectional screw is slidably connected with the sliding plate, the sliding plate and the guide rod are slidably connected, a connecting frame is connected between the two sliding plates, a fixed rod is slidably connected in the connecting frame, an extension plate is slidably connected in the connecting frame, a plurality of fixing grooves are opened on the extension plate, and the fixing rod is engaged with the fixing groove.

[0007] As a further preferred solution, it also includes a first magnet, a second magnet and a limit block. A slot is opened on the connecting frame, the first magnet is symmetrically installed on the connecting frame, the second magnet is installed on the fixed rod, the second magnet is magnetically connected to the first magnet, and the limit block is connected to the fixed rod.

[0008] As a further preferred solution, it also includes a connecting block and a scale bar, the connecting blocks are symmetrically connected to the extension plate, and the scale bar is connected to the front side of the connecting block.

[0009] As a further preferred embodiment, a rotating handle is also included, and the second bidirectional screw rod is connected with the rotating handle.

[0010] As a further preferred solution, the extension plate is in an n-shape.

[0011] As a further preferred solution, the number of the connecting frames is not less than two.

[0012] The beneficial effects of the utility model are as follows: 1. The special-shaped parts can be initially fixed by the clamping plate, and the other two sides of the special-shaped parts can be fixed by adjusting the extension plate, which is convenient for fixing the special-shaped parts before the secondary cutting is completed. If only two sides are fixed, the special-shaped parts are easy to move at will during cutting due to loose fixation. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment: A clamping device for CNC five-axis machine tool processing, such as Figure 1-Figure 7 As shown, it includes a frame 1, a first bidirectional screw rod 2, a clamping plate 3, a mounting plate 4, a guide rod 5, a second bidirectional screw rod 6, a sliding plate 7, a connecting frame 8, a fixing rod 9, an extension plate 10 and a rotating handle 16. The first bidirectional screw rod 2 is rotatably connected in the frame 1, and the first bidirectional screw rod 2 is symmetrically slidably connected with the clamping plate 3 for preliminary fixation. The mounting plates 4 are symmetrically installed on the frame 1, and the guide rods 5 are installed on the two mounting plates 4 on the left. The second bidirectional screw rods 6 are threadedly connected on the two mounting plates 4 on the right for secondary fixation. The second bidirectional screw rod 6 is slidably connected with the sliding plate 7, and the sliding plate 7 is slidably connected to the guide rod 5. A connecting frame 8 is connected between the two sliding plates 7. The number of the connecting frames 8 is not less than two. The fixing rod 9 is slidably connected in the connecting frame 8, and the extension plate 10 is fixed by clamping the fixing groove 11. The extension plate 10 is slidably connected in the connecting frame 8. The shape of the plate 10 is n-shaped, and a plurality of fixing grooves 11 are provided on the extension plate 10. The fixing rod 9 is snap-fitted with the fixing groove 11. The fixing groove 11 is used to adjust the position of the extension plate 10. A rotating handle 16 is connected to the second bidirectional screw rod 6 to facilitate the rotation of the second bidirectional screw rod 6. It also includes a first magnet 13, a second magnet 14 and a limit block 15. A slot 12 is provided on the connecting frame 8. The first magnet 13 is symmetrically installed on the connecting frame 8. The second magnet 14 is installed on the fixing rod 9. The second magnet 14 is magnetically connected to the first magnet 13. The fixing of the fixing rod 9 is achieved by the cooperation of the first magnet 13 and the second magnet 14. The limit block 15 is connected to the fixing rod 9. It also includes a connecting block 17 and a scale bar 18. The connecting blocks 17 are symmetrically connected to the extension plate 10. The scale bar 18 is connected to the front side of the connecting block 17 to observe whether the special-shaped parts are flush after the clamping is completed.

[0023] When the device is needed, when the user needs to clamp the workpiece during the second cutting process, the user first places the cut special-shaped part between the two clamping plates 3, and then rotates the first bidirectional screw 2 to move the two clamping plates 3 inward to fix the special-shaped part, and then rotates the fixing rod 9 clockwise to one hundred and eighty degrees to disengage the first magnet 13 from the second magnet 14, and at the same time the limit block 15 will be aligned with the slot 12, and then the fixing rod 9 is pulled outward, and the fixing rod 9 moves to disengage from the fixing slot 11, and then repeat the above operation to pull out the fixing rod 9 on the same side, at this time the extension plate 10 is in an active state, and then the extension plate 10 is pulled upward to a suitable position to clamp the special-shaped part position, and then insert the fixing rod 9 into the connecting frame 8, and at the same time jam it with the fixing groove 11 at the same position, and then reversely rotate the fixing rod 9 counterclockwise to one hundred and eighty degrees. At the same time, the second magnet 14 contacts and attracts the first magnet 13 to fix the fixing rod 9, and then rotate the rotating handle 16. The rotating handle 16 drives the second bidirectional screw rod 6, and the second bidirectional screw rod 6 drives the sliding plate 7, the connecting frame 8, the fixing rod 9 and the extension plate 10 to move inward. When the extension plate 10 moves to a suitable position, the extension plate 10 contacts and fixes the special-shaped part, so that the special-shaped part is reinforced. Then, by observing the position of the scale bar 18, it can be judged whether the special-shaped part is flush.
