Technical Field

[0001] The utility model relates to the technical field of machine tool fixtures, in particular to a slot-type machine tool fixing fixture with a replaceable chuck. Background Art

[0002] A machine tool fixture is a device used to clamp workpieces and guide cutting tools on machine tools. It is a common working component on machine tools. Generally, workpieces need to be fixed during machining to prevent the workpieces from shaking or shifting during machining, which causes machining difficulties. At this time, a machine tool fixture is needed.

[0003] The prior art discloses a large plate processing machine tool fixing fixture with application number CN202222216840.4, which includes a base, a worktable, and a workpiece fixture. The upper end of the base is fixedly connected to the worktable, a connecting cavity is provided in the worktable, a driving disk is rotatably connected in the connecting cavity, a spiral groove is provided on the upper end surface of the driving disk, a plurality of slide groove holes that are connected to the connecting cavity are provided on the upper end of the worktable, a sliding guide block is slidably connected in the slide groove hole, the lower end of the sliding guide block is fixedly connected to the driving block, the lower end of the driving block is fixedly connected to a plurality of teeth, the teeth are meshed with the spiral groove, and the sliding guide The upper end of the block is fixedly connected to a workpiece clamp. The purpose of this utility model is to provide a large plate processing machine tool fixing clamp with a simple structure, easy operation and wide applicability; however, during the use of the clamp, it is inevitable that debris or scraps will fall from the slide hole to the inside of the workbench, then when the driving block is in engagement with the meshing teeth and the thread groove, it is very likely to get stuck. Moreover, due to the characteristics of the device, it can only clamp objects of one shape. When objects of different shapes need to be processed, the clamp becomes "incapable of doing so" and has a small scope of application. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a slot-type machine tool fixing fixture with a replaceable chuck to solve the technical problems mentioned in the above background technology.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The utility model is provided with a gear ring, a first gear, a second gear, a gear rod, and a connecting shaft. When clamping an object, the servo motor drives a set of connecting shafts to rotate, thereby causing the first gear to drive the gear ring to rotate.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] Example 1: A slot-type machine tool fixture with a replaceable chuck, such as Figure 1-Figure 4 As shown, it includes a fixed disk 1, a plurality of connecting shafts 19 are provided inside the fixed disk 1, and the ends of the plurality of connecting shafts 19 are provided with second gears 10, the outer surfaces of the plurality of connecting shafts 19 are provided with first gears 9, the inner wall of the fixed disk 1 is provided with a slide rail 7, and the interior of the slide rail 7 is slidably connected with a gear ring 8, the top of the fixed disk 1 is provided with a plurality of sliding sleeves 2, and the interior of the sliding sleeve 2 is provided with a gear rod 3, one end of the gear rod 3 is fixed with a slot 5, the interior of the slot 5 is provided with a chuck 12 through a block 11, and the chuck 12 is provided with four groups, and a silicone pad is provided on one side of the four groups of chucks 12. The four groups of chucks 12 can be aligned with the The front, back, left and right sides of the object are clamped synchronously. The silicone pad is soft. On the one hand, it can increase the friction during clamping, making the clamping more firm. On the other hand, it will not cause wear to the surface of the object. A limiting groove 13 is provided on one side of the clamping block 11. A pull rod 17 is passed through one side of the clamping groove 5, and a connecting plate 14 is fixed to one end of the pull rod 17. A limiting block 15 is fixed on one side of the connecting plate 14, and a spring 16 is fixed on the other side of the connecting plate 14. A pull ring 18 is fixed to the other end of the pull rod 17. Under the action of the pull ring 18, it is more convenient for the staff to pull the pull rod 17 and it is easier to exert force.

[0031] See Figure 2 In the above embodiment, a servo motor 6 is provided at the bottom of the fixed disk 1, and the output end of the servo motor 6 is connected to a set of connecting shafts 19. After the servo motor 6 is started, it can rotate the set of connecting shafts 19, and then, with the cooperation of the first gear 9, the ring gear drives the other first gears 9 to rotate.

[0032] See Figure 1-Figure 3 In the above embodiment, the first gear 9 is engaged with the gear ring 8, and the second gear 10 is engaged with the gear rod 3. When one group of first gears 9 rotates, the gear ring 8 rotates, and the rotation of the gear ring 8 rotates other groups of first gears 9, thereby causing the connecting shaft 19 to synchronously drive multiple groups of gear rods 3 to move.

[0033] See Figure 1-Figure 4 In the above embodiment, the clamping block 11 is adapted to the clamping slot 5, and the limiting block 15 is adapted to the limiting slot 13. With the cooperation between the clamping block 11 and the clamping slot 5, it is convenient to replace the clamp 12 of the fixture. With the cooperation between the limiting block 15 and the limiting slot 13, the clamping block 11 and the clamping slot 5 are more stable after assembly.

[0034] Example 2: In order to facilitate the installation of the fixture, Example 2 is improved on the basis of Example 1. Figure 1-Figure 2 A plurality of mounting members 20 are provided around the bottom edge of the fixed plate 1 , and the staff can fix the fixture on the machine tool through the plurality of mounting members 20 .

[0035] Example 3: In order to make the gear rod more stable during linear motion, Example 3 is improved on the basis of Example 1. Figure 1-Figure 3 A slide bar 4 is provided at the bottom of the slot 5, and the slide bar 4 is slidably matched with the sliding sleeve 2. With the cooperation of the slide bar 4, the gear rod 3 is more stable during linear motion.

[0036] The implementation principle of the present invention is as follows: the staff first installs the clamp on the machine tool through the mounting piece 20. When clamping the object, the staff starts the servo motor 6, and the servo motor 6 drives a set of connecting shafts 19 to rotate, thereby causing the first gear 9 to drive the gear ring to rotate. When the gear ring rotates, it will drive other sets of first gears 9 and connecting shafts 19 to rotate, thereby causing multiple sets of second gears 10 to rotate synchronously. After the second gear 10 rotates, it will cause multiple sets of gear rods 3 to move linearly in the middle direction, so that the chuck 12 can clamp the object. If the shape of the object to be clamped is the same as that of the original chuck, When 12 does not match, the staff can pull the pull rod 17 to disengage the limit block 15 from the limit slot 13, so that the card block 11 can be slid out of the card slot 5 to remove the original chuck 12, and then find the chuck 12 that matches the item. During installation, the pull rod 17 is also pulled first, the limit block 15 moves to one side, and then the card block 11 is stuck in the card slot 5, and the pull rod 17 is released. With the cooperation of the spring 16, the limit block 15 will be stuck in the limit slot 13, thereby achieving the assembly purpose between the card slot 5 and the card block 11, so that the whole can meet the usage requirements in different usage situations.
