Description

Technical Field

[0001] This utility model relates to the technical field of needle implantation machine worktable clamps, and specifically discloses a quick-change needle implantation machine worktable clamp. Background Technology

[0002] A needle implantation machine is an automated device used to precisely implant bristles (nylon filaments, pig bristles, steel wire, etc.), metal needles, or other similar slender parts into pre-drilled holes in a brush base (plastic, wood block, metal plate, etc.). It is commonly used in the manufacture of toothbrushes, industrial brushes, cleaning brushes, and needle plates. The workbench fixture refers to the device mounted on the work platform of the needle implantation machine, used to firmly and accurately fix the workpiece (i.e., the brush base) during the needle implantation process. Since brush bases come in various shapes, a workbench fixture matching the brush base must be used when clamping and fixing different brush bases.

[0003] The existing needle implantation machine worktable mostly uses bolt-fixed clamp modules. When replacing the clamp modules, multiple fasteners need to be disassembled, which takes a long time and affects production efficiency. Especially in multi-variety, small-batch production, frequent replacement of clamp modules leads to low equipment utilization and inconvenience. Utility Model Content

[0004] This utility model proposes a quick-change needle implantation machine worktable fixture, which can facilitate and quickly replace the fixture module, avoid affecting production efficiency, and is easy to use.

[0005] This utility model is implemented as follows: a quick-change needle implantation machine worktable fixture includes a worktable body and a fixture module disposed on the upper end face of the worktable body, wherein a quick-release structure is provided between the worktable body and the fixture module.

[0006] The quick-release structure includes an annular groove on the upper surface of the workbench body, a first cavity inside the workbench body, two symmetrically distributed pins slidingly connected inside the first cavity, a groove on the lower surface of the clamp module, the clamp module being located inside the annular groove, and slots matching the two pins being provided on the front and rear inner walls of the groove.

[0007] As a preferred embodiment of the quick-change needle implantation machine workbench fixture of this utility model, the first cavity has two left-right distributed rotating shafts rotatably connected inside, and gears are fixedly connected to the outer walls of the two rotating shafts. The two pins have racks fixedly connected to the opposite side walls of each side wall, which are respectively meshed with the two gears.

[0008] As a preferred embodiment of the quick-change needle implantation machine workbench fixture of this utility model, the workbench body has a second cavity located below the first cavity. The lower ends of the two rotating shafts extend into the interior of the second cavity and are fixedly connected to worm gears. The interior of the second cavity is rotatably connected to a worm gear that meshes with the two worm gears.

[0009] As a preferred embodiment of the quick-change needle insertion machine workbench fixture of this utility model, the front and rear inner walls of the first cavity are provided with through holes, and one end of each of the two pins passes through the two through holes and extends into the interior of the two slots.

[0010] In a preferred embodiment of the quick-change needle insertion machine workbench fixture of this utility model, the lower end faces of the two pins are slidably connected to the lower end of the first cavity via trapezoidal sliders and trapezoidal grooves.

[0011] As a preferred embodiment of the quick-change needle implantation machine workbench fixture of this utility model, the front end of the worm gear extends to the front of the workbench body and is fixedly connected with a torsion block.

[0012] The beneficial effects of this utility model are:

[0013] When disassembling the fixture module, the interaction between the worm gear, two worm wheels, two rotating shafts, two gears, and two racks drives the two pins to move in opposite directions, causing them to move out of their respective slots. Then, the fixture module is removed from the annular groove, thus disassembling the fixture module. When installing the fixture module, different fixture modules are placed into the annular groove, and then the above steps are reversed. This allows for convenient and quick replacement of the fixture module, avoiding impact on production efficiency and facilitating its use. Attached Figure Description

[0020] Please see Figure 1-3 A quick-change needle implantation machine workbench fixture includes a workbench body 1 and a fixture module 2 disposed on the upper end face of the workbench body 1, and a quick-release structure is provided between the workbench body 1 and the fixture module 2.

[0021] The quick-release structure includes an annular groove 3 on the upper surface of the workbench body 1, a first cavity 4 inside the workbench body 1, two symmetrically distributed pins 5 slidingly connected inside the first cavity 4, a groove 6 on the lower surface of the clamp module 2, the clamp module 2 being located inside the annular groove 3, and slots 7 matching the two pins 5 respectively on the front and rear inner sidewalls of the groove 6.

[0022] In this embodiment: when disassembling the clamp module 2, the two pins 5 move in opposite directions, causing them to move out of the two slots 7 and into the two through holes 14 respectively, thereby releasing the clamp module 2 from its limiting and fixing state by the two pins 5 and the two slots 7. Then, the clamp module 2 is lifted upwards, causing it to move out of the annular groove 3, thus disassembling the clamp module 2. When installing the clamp module 2, different clamp modules 2 are placed into the annular groove 3, and then the above steps are reversed. This allows for convenient and quick replacement of the clamp module 2, avoiding impact on production efficiency and facilitating its use.

[0023] As a technical optimization of this utility model, the first cavity 4 is rotatably connected to two left and right distributed rotating shafts 8. The outer walls of the two rotating shafts 8 are fixedly connected to gears 9. The side walls of the two pins 5 opposite to each other are fixedly connected to racks 10 that mesh with the two gears 9 respectively.

[0024] In this embodiment: the two rotating shafts 8 rotate, and the two rotating shafts 8 respectively drive the two gears 9 to rotate. The two gears 9, together with the two racks 10, respectively drive the two pins 5 to move in opposite directions.

[0025] As a technical optimization of this utility model, the workbench body 1 has a second cavity 11 located below the first cavity 4. The lower ends of the two rotating shafts 8 extend into the interior of the second cavity 11 and are fixedly connected to worm gears 12. The interior of the second cavity 11 is rotatably connected to a worm 13 that meshes with the two worm gears 12.

[0026] In this embodiment: the worm gear 13 rotates, which drives the two worm wheels 12 to rotate, and the two worm wheels 12 drive the two rotating shafts 8 to rotate respectively.

[0027] As a technical optimization of this utility model, the front and rear inner walls of the first cavity 4 are provided with through holes 14, and one end of each of the two pins 5 passes through the two through holes 14 and extends into the interior of the two slots 7.

[0028] In this embodiment, the pin 5 can be removed from the first cavity 4 and enter the slot 7 through the through hole 14.

[0029] As a technical optimization of this utility model, the lower end faces of the two pins 5 are slidably connected to the lower end of the first cavity 4 through trapezoidal sliders and trapezoidal grooves.

[0030] In this embodiment, the trapezoidal slider and trapezoidal groove enable the two pins 5 to move smoothly.

[0031] As a technical optimization of this utility model, the front end of the worm gear 13 extends to the front of the workbench body 1 and is fixedly connected to the torsion block 15.

[0032] In this embodiment, the worm gear 13 can be rotated by the torsion block 15.

[0033] The working principle and usage process of this utility model are as follows: When disassembling the clamp module 2, the torsion block 15 drives the worm gear 13 to rotate, the worm gear 13 drives the two worm wheels 12 to rotate, the two worm wheels 12 drive the two rotating shafts 8 to rotate, the two rotating shafts 8 drive the two gears 9 to rotate, and the two gears 9, in conjunction with the two racks 10, drive the two pins 5 to move in opposite directions, so that the two pins 5 are removed from the two slots 7 and enter the two through holes 14 respectively, thereby releasing the limiting and fixing state of the clamp module 2 by the two pins 5 and the two slots 7. Then, the clamp module 2 is lifted upwards, so that the clamp module 2 is removed from the annular groove 3, and the clamp module 2 is disassembled. When installing the clamp module 2, different clamp modules 2 are placed into the annular groove 3, and then the above steps are reversed.
