Description

Technical Field

[0001] This utility model belongs to the field of machine tool chuck technology, specifically a modular machine tool chuck with quick clamp changing. Background Technology

[0002] A machine tool chuck is a mechanical device used to fix workpieces. It is mainly used on various machine tools such as lathes, milling machines, and CNC machine tools. By clamping the workpiece, it keeps it stable during machining, thereby enabling rotation, cutting, or other machining operations. The three-jaw chuck is a common type of machine tool chuck. Existing three-jaw chucks typically design the clamping ends of the jaws in a triangular shape. This design has the advantage of accurate positioning when clamping solid objects, but when clamping hollow tubes, it is easy to compress and deform them, affecting product quality. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a modular machine tool chuck with quick clamping, which solves the problem that existing three-jaw chucks usually design the clamping ends of the jaws as triangles, which easily compress and deform hollow tubes when clamping them, affecting product quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular machine tool chuck with quick clamp changing, comprising a three-jaw chuck body, three movable plates on the three-jaw chuck body, a fixed rod fixedly connected to the movable plate, a blocking plate fixedly connected to one end of the fixed rod, two limiting grooves on the blocking plate, a rotating plate rotatably connected to the front of the movable plate, two screws threadedly connected to the rotating plate, one end of the screws located inside the limiting groove, a triangular clamping block provided at one end of the rotating plate, an arc-shaped clamping block provided at the other end of the rotating plate, a T-shaped hole provided on the rotating plate, and the fixed rod and the blocking plate both located inside the T-shaped hole.

[0005] As a further embodiment of this utility model: a nut is fixedly connected to one end of the screw, and the nut has several grooves.

[0006] As a further embodiment of this utility model: both the triangular clamping block and the arc-shaped clamping block are fixedly connected to mounting plates, and the mounting plates are provided with limit holes.

[0007] As a further embodiment of this utility model: two placement slots are provided on the rotating plate, and the mounting plate is located inside the placement slots.

[0008] As a further embodiment of this utility model: two screws are threadedly connected to the rotating plate, and one end of each screw is located inside the limiting hole.

[0009] As a further embodiment of this utility model, the number of both the triangular clamping block and the arc-shaped clamping block is three.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This modular machine tool chuck with quick-change clamping mechanism features an arc-shaped clamping block, a triangular clamping block, a rotating plate, a limiting groove, and a screw. When clamping hollow tubes, rotating the nut drives the screw to rotate. Since the screw is threaded onto the rotating plate, it moves as it rotates, disengaging from the limiting groove and releasing the rotating plate from its fixed position. The rotating plate can then be rotated 180 degrees, and the nut rotated in the opposite direction to rotate the screw, causing it to move and insert into the limiting groove, thus fixing the rotating plate. This switches the triangular clamping block to the arc-shaped clamping block. Operating the three-jaw chuck body brings the three moving plates, the rotating plate, and the arc-shaped clamping block closer together, clamping and fixing the hollow tube. This machine tool chuck can quickly switch between the triangular and arc-shaped clamping blocks according to actual needs. The triangular clamping block offers accurate positioning when clamping solid objects, while the arc-shaped clamping block prevents deformation of hollow tubes, thus ensuring product quality.

[0012] 2. This modular machine tool chuck with quick-change clamping features screws, placement slots, mounting plates, and limiting holes. When the triangular clamping blocks need to be disassembled, first tighten the screws to move them out of the limiting holes, thus releasing the mounting plate from the triangular clamping blocks. Then, the triangular clamping blocks can be disassembled. When the triangular clamping blocks need to be installed, place the mounting plate in the placement slots and reverse the screws to move them into the limiting holes, thus fixing the mounting plate to the triangular clamping blocks and completing the installation. The same principle applies to disassembling and installing the curved clamping blocks. This modular design of triangular and curved clamping blocks facilitates quick assembly and disassembly of these blocks, allowing for rapid replacement of severely worn triangular and curved clamping blocks.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a modular machine tool chuck with quick clamp changing, including a three-jaw chuck body 1, three movable plates 2 are provided on the three-jaw chuck body 1, a fixed rod 6 is fixedly connected to the movable plate 2, and a blocking plate 7 is fixedly connected to one end of the fixed rod 6. Because of the blocking plate 7, the blocking plate 7 can block the rotating plate 3, and can ensure that the rotating plate 3 will not detach from the movable plate 2 when rotating. Two placement slots 12 are opened on the rotating plate 3, and the mounting plate 13 is located inside the placement slot 12.

[0020] Two limiting grooves 8 are provided on the blocking plate 7. A rotating plate 3 is rotatably connected to the front of the moving plate 2. Two screws 10 are threadedly connected to the rotating plate 3. A nut 11 is fixedly connected to one end of the screw 10. Several grooves are provided on the nut 11. Because several grooves are provided on the nut 11, friction can be increased, making it easier for personnel to rotate the nut 11 and improving the ease of operation.

[0021] One end of the screw 10 is located inside the limiting groove 8. One end of the rotating plate 3 is provided with a triangular clamping block 4. Because of the triangular clamping block 4, it has the advantage of accurate positioning when clamping solid objects. The other end of the rotating plate 3 is provided with an arc-shaped clamping block 5. Because of the arc-shaped clamping block 5, it is not easy to deform the hollow tube when clamping it, thus ensuring product quality. Two screws 15 are threaded on the rotating plate 3. Because of the screws 15, by rotating the screws 15, they are inserted into the limiting hole 14 to fix the mounting plate 13 and the triangular clamping block 4, thereby improving the stability of the triangular clamping block 4. One end of the screw 15 is located inside the limiting hole 14.

[0022] The rotating plate 3 has a T-shaped hole 9. The fixing rod 6 and the blocking plate 7 are both located inside the T-shaped hole 9. The triangular clamping block 4 and the arc-shaped clamping block 5 are both fixedly connected to the mounting plate 13. The mounting plate 13 has a limit hole 14. There are three triangular clamping blocks 4 and three arc-shaped clamping blocks 5.

[0023] The working principle of this utility model is as follows:

[0024] When it is necessary to clamp the hollow pipe, rotate the nut 11 to drive the screw 10 to rotate. Since the screw 10 is threadedly connected to the rotating plate 3, it will move while rotating, thereby causing the screw 10 to disengage from the limiting groove 8 and release the fixed state of the rotating plate 3. At this time, the rotating plate 3 can be rotated 180 degrees, and the nut 11 can be rotated in the opposite direction to drive the screw 10 to rotate, so that the screw 10 moves and inserts into the limiting groove 8, thereby fixing the rotating plate 3, thereby switching the triangular clamping block 4 to the arc-shaped clamping block 5. At this time, operate the three-jaw chuck body 1 to bring the three moving plates 2, the rotating plate 3 and the arc-shaped clamping block 5 closer to each other, thereby clamping and fixing the hollow pipe.

[0025] When it is necessary to disassemble the triangular clamp 4, first turn the screw 15 to move the screw 15 and disengage it from the limiting hole 14, thereby releasing the fixed state between the mounting plate 13 and the triangular clamp 4. At this time, the triangular clamp 4 can be disassembled. When it is necessary to install the triangular clamp 4, place the mounting plate 13 inside the placement groove 12, and turn the screw 15 in the opposite direction to move the screw 15 and insert it into the limiting hole 14, thereby fixing the mounting plate 13 and the triangular clamp 4, and completing the installation of the triangular clamp 4. The same principle applies when disassembling and installing the arc-shaped clamp 5.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
