DETAILED DESCRIPTION
[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0026] Example 1: Figure 1 to Figure 5 As shown, this embodiment proposes a special clamp for cutting gaskets, including a clamp table 1, an internal expansion chuck 6 and a clamp chassis 8. A threaded hole is provided on one side of the clamp table 1, and a sleeve base 2 is provided on the outer wall of the top of the clamp table 1. The sleeve base 2 is fixedly installed on the outer wall of the clamp table 1 by fixing bolts 7. The inner walls on both sides of the sleeve base 2 are movably connected with threaded sleeves 4 through rotating shafts. Threaded rods 5 are provided on the inner walls of the sleeve base 2 and the threaded sleeves 4. A handle 3 is installed at one end of the threaded rod 5. A cone 10 is connected to the other end of the threaded rod 5. The cone 10 is installed in the inner cavity of the clamp chassis 8.
[0027] A slide groove 14 and a limit groove 15 are provided inside the clamp chassis 8, the inner wall of the slide groove 14 is installed with the inner expansion chuck 6, the outer wall of the top of the inner expansion chuck 6 is installed with a limit block 11, the side wall of the limit block 11 is installed with a telescopic rod 13, and the outer wall of the telescopic rod 13 is installed with a spring 12. This structure can keep the inner expansion chuck 6 closed under normal circumstances and will not loosen due to internal expansion.
[0028] The outer end of the inner expansion chuck 6 is fan-shaped, and the front section of the inner expansion chuck 6 is provided with a 90° conical groove, which matches the cone 10. This structure enables the side wall of the cone 10 to squeeze the inner expansion chuck 6 outward when it moves downward, so that it expands and clamps the gasket.
[0029] Four inner expansion chucks 6 are installed on the inner wall of the clamp chassis 8. The inner expansion chucks 6 are in a circular ring shape as a whole. This structure can clamp gaskets of any thickness and aperture.
[0030] An empty slot matching the aperture of the front section of the cone 10 is provided at the center of the clamp chassis 8 , and the threaded rod 5 penetrates through the outer wall of the clamp chassis 8 and is connected to the clamp chassis 8 .
[0031] Specific as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when using this structure, the handle 3 is pressed down by hand to make the clamp chassis 8 rise from the inside of the chassis slot 9 as a whole, and the gasket is placed on the outer wall of the inner expansion chuck 6. The clamp chassis 8 is restored to its original position by releasing the hand, and the sleeve base 2 is manually rotated to rotate the threaded rod 5 so that the threaded rod 5 moves to the side away from the clamp, thereby pulling the cone 10 to move inside the clamp chassis 8, so that the side wall of the cone 10 presses the inner expansion chuck 6 outward, so that the inner expansion chuck 6 expands outward and inward along the slide groove 14, clamps the gasket, and cuts and grinds it. This structure solves the problem that the gasket is too thin and inconvenient to clamp.
[0032] Embodiment 2: In this embodiment, a chassis slot 9 is provided at the top of the fixture table 1, and the fixture chassis 8 is installed on the inner wall of the chassis slot 9. This structure facilitates the disassembly of the fixture and can also limit the fixture as a whole to prevent the fixture from loosening.
[0033] The front half bearing of the threaded rod 5 is movably connected to the threaded section, the outer wall of the threaded rod 5 is provided with an external thread, the inner wall of the threaded sleeve 4 is provided with an internal thread matching the external thread, and the sleeve base 2 is provided with a half-hole groove matching the threaded rod 5.
[0034] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when this structure is used, when the clamp needs to be adjusted in position or disassembled for maintenance, a wrench is used to pull out the studs that movably connect the sleeve base 2 and the threaded sleeve 4, so as to separate the sleeve base 2 and the threaded sleeve 4, and the clamp body including the handle 3 and the threaded rod 5 is taken away. The fixing bolt 7 is turned with a screwdriver to make it fall off, and the sleeve base 2 is removed from the outer wall of the clamp table 1. This structure is simple and convenient for disassembly and maintenance of the clamp.
[0035] Working principle: When using this structure, manually press the handle 3 to make the clamp body leave the inside of the chassis slot 9, put the gasket on the outer wall of the inner expansion chuck 6, release the hand to make the clamp chassis 8 return to its original position, rotate the sleeve base 2 clockwise to make the threaded rod 5 move to the side away from the clamp, pull the cone 10 to move in the same direction, so that the cone 10 squeezes the inner expansion chuck 6 outward through the side wall during the movement, so that the inner expansion chuck 6 expands outward and inward along the slide groove 14 to clamp the gasket, until the inner expansion chuck 6 is tightly clamped from the inner wall of the gasket, stop rotating the handle 3 clockwise, The gasket is polished, and because the bearing and the threaded section at the front end of the threaded rod 5 are movably connected, the outer wall can be polished in all directions while rotating the gasket without adjusting the fixture. When the fixture needs to be adjusted or disassembled, the studs that movably connect the sleeve base 2 and the threaded sleeve 4 are pulled out, the sleeve base 2 and the threaded sleeve 4 are separated, and the fixture body including the handle 3 and the threaded rod 5 is taken out. The fixing bolt 7 is turned with a screwdriver to make it fall off, and the sleeve base 2 is removed from the outer wall of the fixture table 1. This structure is simple and easy to disassemble and assemble, and can clamp gaskets of any thickness.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
