Description

Technical Field

[0001] This utility model relates to the technical field of machining, specifically a double-fixed mechanism for spinning tools in a CNC spinning machine. Background Technology

[0002] A CNC spinning machine is a machine tool used for spinning metal. Metal spinning refers to the process where a sheet metal blank is axially clamped in a forming die, and the die and blank rotate under the drive of two shafts. Simultaneously, the blank is continuously squeezed radially by forming wheels, causing the metal blank to gradually deform and ultimately form the desired shape on both the axial surface and the outer cylindrical surface. This forming process involves the flow and plastic deformation of metal. Appropriate selection of the metal blank material, spinning forming wheels, spinning pressure, and feed speed can create a metal surface with high hardness, high wear resistance, and high gloss.

[0003] As an extrusion tool for spinning metal, the spinning cutter wheel must have high stability; otherwise, the produced product will deviate from the set shape. In addition, different shapes of spinning cutters are required to produce different products. In order to ensure the stability of the spinning cutter wheel, the structure between the spinning cutter wheel and the support shaft is very complex and inconvenient to disassemble and replace. Utility Model Content

[0004] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a double-fixed mechanism for spinning cutters of a CNC spinning machine, comprising:

[0005] The tool holder is pre-installed on the spinning machine;

[0006] The grooves are in pairs, both formed within the tool holder;

[0007] A rotating rod is rotatably mounted inside the tool holder, with both ends extending out of the tool holder;

[0008] A pair of flipping rods are fixedly connected to both ends of the rotating rod, respectively.

[0009] The rotating shaft has two ends respectively located in a pair of grooves and respectively in contact with a pair of rotating rods;

[0010] A spinning cutter wheel is rotatably mounted on the outer surface of the rotating rod;

[0011] A locking block, connected to one end of the flipping rod and disposed in the groove, is used to lock one end of the rotating shaft;

[0012] An adjustment mechanism, located inside the flipping rod, is used to drive the locking block to move.

[0013] Preferably, the adjustment mechanism includes;

[0014] A placement groove is formed within one end face of the flipping rod;

[0015] An internally threaded sleeve is disposed in the placement groove and is fixedly connected to the locking block;

[0016] The threaded rod has one end rotatably connected to the inner wall of the placement groove, and the other end threadedly connected to the internal threaded sleeve.

[0017] Preferably, a worm gear is fixedly installed on the outer surface of the threaded rod, and a worm that meshes with the worm gear is rotatably installed in the placement groove.

[0018] Preferably, a pair of locking grooves are formed in the outer wall of the tool holder, a through hole is formed in the flip rod, a locking rod is slidably installed in the through hole, one end of the locking rod is inserted into the locking groove, and an elastic element is wound around the outer surface of the locking rod.

[0025] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] This utility model proposes a double-fixed mechanism for spinning tools of a CNC spinning machine, comprising:

[0027] Tool holder 1 is pre-installed on the spinning machine;

[0028] Grooves 2, there are a pair, both formed inside the tool holder 1;

[0029] Rotating rod 3 is rotatably installed inside tool holder 1, and both ends extend out of tool holder 1 respectively;

[0030] There is a pair of flipping rods 4, which are fixedly connected to both ends of the rotating rod 3 respectively;

[0031] The rotating shaft 5 has two ends respectively located in a pair of grooves 2 and respectively in contact with a pair of rotating rods 3;

[0032] The spinning wheel 6 is rotatably mounted on the outer surface of the rotating rod 3;

[0033] The spinning wheel 6 contacts the external workpiece and rotates on the rotating shaft 5, which can perform spinning processing on the workpiece;

[0034] The locking block 7 is connected to one end of the flipping rod 4 and is located in the groove 2, and is used to lock one end of the rotating shaft 5.

[0035] Under the action of the rotating rod 3, a pair of flipping rods 4 can be flipped at the same time and contact the two ends of the rotating shaft 5 respectively, which can limit the rotating shaft 5 and prevent the rotating shaft 5 from moving in the axial and radial directions. At the same time, a pair of locking blocks 7 can restrict the two ends of the rotating shaft 5, so that it is stably placed in a pair of grooves 2.

[0036] An adjustment mechanism, located inside the flip rod 4, is used to drive the locking block 7 to move.

[0037] Specifically, the regulatory bodies include;

[0038] The placement groove 8 is formed in one end face of the flipping rod 4;

[0039] The internal threaded sleeve 9 is located in the placement groove 8 and is fixedly connected to the locking block 7;

[0040] The threaded rod 10 has one end rotatably connected to the inner wall of the placement groove 8, and the other end threadedly connected to the internal threaded sleeve 9.

[0041] The rotation of the threaded rod 10 can drive the internal threaded sleeve 9 to move in the placement groove 8. At this time, the movement of the internal threaded sleeve 9 can drive the locking block 7 to move out of the groove 2, making it convenient to remove the rotating shaft 5 from the pair of grooves 2.

[0042] Specifically, a worm gear 11 is fixedly installed on the outer surface of the threaded rod 10, and a worm 12 that meshes with the worm gear 11 is rotatably installed in the placement groove 8.

[0043] The rotation of worm 12 can drive worm wheel 11 to rotate simultaneously, and the rotation of worm wheel 11 can drive threaded rod 10 to rotate simultaneously. At the same time, under the action of worm wheel 11 and worm 12, the rotation of threaded rod 10 can be prevented, thus preventing locking block 7 from loosening.

[0044] Specifically, a pair of locking grooves 13 are formed in the outer wall of the tool holder 1, a through hole 14 is formed in the flipping rod 4, a locking rod 15 is slidably installed in the through hole 14, one end of the locking rod 15 is inserted into the locking groove 13, and an elastic element 16 is wound on the outer surface of the locking rod 15. The two ends of the elastic element 16 are fixedly connected to the inner wall of the through hole 14 and the outer surface of the locking rod 15, respectively.

[0045] The elastic element 16 is a tension spring, which can apply a force to the locking rod 15 so that one end of it is always inserted into the locking groove 13, thereby fixing the flipping rod 4 relative to the tool holder 1.

[0046] Specifically, a limiting groove 17 is formed in the inner wall of the placement groove 8, and a limiting slider 18 that is slidably connected to the limiting groove 17 is fixedly installed on the outer surface of the internal thread sleeve 9.

[0047] Under the action of the limiting slide groove 17 and the limiting slider 18, the internal threaded sleeve 9 can remain stable when moving in the placement groove 8 and will not rotate.

[0048] Working principle: When it is necessary to replace the spinning cutter wheel 6 in actual use, first rotate a pair of worm gears 12. The rotation of the worm gears 12 can drive the worm wheel 11 to rotate simultaneously. The rotation of the worm wheel 11 can drive the threaded rod 10 to rotate simultaneously. The rotation of the threaded rod 10 can drive the internal threaded sleeve 9 to move in the placement groove 8. At this time, the movement of the internal threaded sleeve 9 can drive the locking block 7 to move, causing it to move out of the groove 2. At this time, pull a pair of locking rods 15, so that one end of each rod separates from a pair of locking grooves 13. Then, the flipping rod 4 can be flipped to easily remove the rotating shaft 5 and the spinning cutter wheel 6, and the new rotating shaft 5 can be placed in the groove 8. The rotating pressure wheel 6 is reinstalled so that both ends of the replacement shaft 5 are installed in a pair of grooves 2. At this time, the pair of rotating rods 4 are flipped. Simultaneously, under the action of the elastic element 16, a force is applied to the locking rod 15, causing one end of it to be inserted into the locking groove 13, thus locking the rotating rod 4. Then, the pair of worm gears 12 are rotated. The rotation of the worm gears 12 can drive the worm wheel 11 and the threaded rod 10 to rotate simultaneously. The rotation of the threaded rod 10 can drive the internal threaded sleeve 9 to move into the placement groove 8, and drive the locking block 7 to move into the groove 2, locking both ends of the shaft 5, completing the replacement and bringing convenience to people.
