DETAILED DESCRIPTION

[0015] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1 As shown, the disassembly device of this embodiment includes: a handle 1, a clamping nut 2, a gasket 3, a clamping claw 4, a clamping screw 5, a clamp base 6, a cotter pin 7, a pin shaft 1 8, a pin shaft 2 9, a clamping device 10, a crank 11, a turntable 12, a connecting rod 13, a support frame 14, a protective cover 15, a disassembly wrench 16, a disassembly platform 17, and a clamp 18.

[0017] The handle 1 is two cylinders bent into an L shape, and the shorter section has a flat outer side. It is used to fix on both sides of the clamping nut 2. By alternately turning the handle 1 to rotate the clamping nut 2, the clamping nut 2 is tightened and loosened. The clamping nut 2 is a cylindrical column with a special coarse thread on the inside. The clamping nut 2 is used in conjunction with the clamping screw 5. The clamping nut 2 is rotated to tighten or loosen the clamping jaw 4 to complete the clamping. The gasket 3 is a flat ring, which is sleeved on the clamping screw 5 and serves as a buffer for the clamping nut 2 and the clamping jaw 4, protecting the clamping nut 2 and the clamping jaw 4 and preventing them from loosening. The clamping jaw 4 is an arc-shaped pressure plate. The clamping jaw 4 is hinged with the fixture base 6 by a pin shaft. The clamping jaw 4 is assembled with the clamping device 10 by screws. The clamping jaw 4 fits with the fixture base 6 and is pressed by the clamping nut 2. The inner arc of the combination of the clamping jaw 4 and the fixture base 6 is used to clamp the workpiece. The clamping screw 5 is a round handle screw, one end of which is a flat ring and the other end is a special bolt. The clamping screw 5 is hinged with the clamp base 6 by a pin shaft, and the clamping nut 5 is used to tighten the clamped workpiece when in use. The clamp base 6 is a concave rectangular parallelepiped, which is fixed to the disassembly platform 17 by bolts. The left and right ends are respectively hinged with the clamping jaws 4 and the clamping screw 5 by pin shafts. The upper concave surface and the clamping device 10 are assembled with screws, and the clamp base 6 and the clamping jaws 4 cooperate to clamp the workpiece. The clamping device 10 is two stepped semi-cylinders, and four screw holes are evenly distributed on the upper plane for fixing with the clamping jaws 4 and the clamp base 6. The inner arc surface of the cylinder is bonded with a clamping pad to increase friction. The clamping device 10 directly acts on the workpiece, and the type is changed by replacing the clamping device 10 when in use. The crank 11 is a cone, and the small end is connected to the turntable 12 by a thread. The crank 11 is shaken to rotate the turntable 12. The turntable 12 is a circular disk, and the center hole of the turntable 12 is connected to the connecting rod 13 by a flat key. The turntable 12 is rotated to output the torque required for disassembly. The connecting rod 13 is a round rod, one end of which is fixed on the turntable 12, and the other end is connected to the disassembly wrench 16 by a jackscrew. The connecting rod 13 is connected to the support frame 14 by a bearing, and the connecting rod 13 is used to adjust the position and transmit torque. The support frame 14 is an angle steel bracket, which is placed on the ground and connected to the protective cover 15. When in use, it supports and balances the connecting rod 13. The protective cover 15 is a thick steel plate, which is fixed to the ground by bolts. The two sides of the protective cover 15 are respectively fixed to the support frame 14 and the disassembly platform 17. When in use, the protective cover 15 separates the operator from the working area. The disassembly wrench 16 is a stepped cylinder, the side of the large cylinder is a protruding wrench claw, and the small cylinder is longer and fixed to the connecting rod 13. The disassembly wrench 16 directly acts on the workpiece to be disassembled. The disassembly platform 17 is a square platform placed on the ground, with the side surface fixed to the protective cover 15 and the top surface fixed with a fixture, and is used to fix the fixture to place the workpiece when in use.

[0018] Working process

[0019] At the beginning of disassembly, replace the corresponding clamp device 10 according to the required size, adjust the clamp base 6 to the corresponding height, retract the disassembly wrench 16 to the right to the maximum, open the clamp jaws 4, place the cartridge in the concave surface of the clamp base 6, the bottom edge of the cartridge is close to the clamp base 6, close the jaws 4, pull the clamping screw 5 into the screw groove of the jaws 4, tighten the clamping nut 2 to fix the cartridge, push the turntable 12 to make the disassembly wrench 16 close to the bottom surface of the cartridge, slowly turn the turntable 12 to put the wrench claw of the disassembly wrench 16 into the primer wrench groove, pull the turntable 12 to loosen the primer, shake the crank 11 to rotate the turntable 12 to remove the primer, withdraw the disassembly wrench 16, loosen the clamping nut 2, open the clamping screw 5, open the jaws 4, and remove the cartridge and primer. When the product type is not changed, there is no need to replace the clamping device 10 and adjust the height of the clamp base 6. The next cartridge can be directly put in and clamped, and the disassembly work can be carried out by pushing and rotating the wrench.

[0020] This embodiment clamps the cartridge with a clamp and positions it with the bottom edge of the cartridge, uses a protective cover to separate the working area from people, uses a turntable to adjust the position of the disassembly wrench and output sufficient torque, uses the replacement of the clamping device to achieve conversion to different varieties, and rotates the crank to drive the disassembly wrench to achieve safe disassembly of the primer.

[0021] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements should also be considered to belong to the protection scope of the present invention.
