Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 4 A slotted plug slotting device comprises an L-shaped placement plate 1 and a milling cutter 5. A sliding opening is horizontally provided on the upper surface of the placement plate 1, and a workpiece block 2 is slidably arranged in the sliding opening. A lifting cylinder 3 is fixedly installed on the lower surface of the workpiece block 2. A driving motor 4 is fixedly installed on the bottom end of the driving shaft of the lifting cylinder 3, and a mounting block 6 is fixedly installed on the bottom end of the output shaft of the driving motor 4. Two L-shaped mounting plates 7 are symmetrically fixedly installed on the surface of the top of the milling cutter 5. A locking opening 8 is provided on the surface of the mounting plate 7. The workpiece block 2 is controlled to move laterally by a driving component. The driving component comprises a fixing plate fixedly installed on the side wall of the placement plate 1 and an electric telescopic rod 15 fixedly installed on the surface of the fixing plate. The output shaft of the electric telescopic rod 15 penetrates the sliding opening and is fixedly connected to the workpiece block 2.

[0023] The electric telescopic rod 15 can control the milling cutter 5 to move horizontally, the lifting cylinder 3 can control the milling cutter 5 to move longitudinally, and the driving motor 4 can drive the milling cutter 5 to rotate;

[0024] A mounting opening is provided on the surface of the mounting block 6, and through openings are provided on the left and right side walls of the mounting block 6. A locking rod 9 for passing through the locking opening 8 is slidably arranged in the through opening, and a moving block 10 is fixedly installed on one end of the locking rod 9 located in the mounting opening, and the locking rod 9 is connected to the mounting block 6 through a telescopic component, and the telescopic component includes a telescopic spring 16 sleeved on the locking rod 9, and the two ends of the telescopic spring 16 are respectively fixedly connected to the wall of the mounting opening and the surface of the moving block 10, and a spring rod 11 is fixedly installed on the surface of the mounting block 6, and a moving plate 12 is fixedly installed on the lower surface of one end of the spring rod 11 through a connecting rod, and a pressing rod 13 is symmetrically fixedly installed on the lower surface of the moving plate 12, and a straight opening 21 is horizontally provided on the upper surface of the moving block 10, and an oblique opening 14 connected to the straight opening 21 is horizontally provided on the upper surface of the moving block 10, and two pressing rods 13 are respectively slidably arranged in the two straight openings 21;

[0025] When the milling cutter 5 needs to be installed, first, the two pressing rods 13 are moved by controlling the spring rod 11 to contract. During the movement, the bottom ends of the two pressing rods 13 will enter the two oblique openings 14 from the two straight openings 21 respectively, and the bottom end surfaces of the pressing rods 13 will abut against the walls of the oblique openings 14. Under the pressure of the two pressing rods 13, the two moving blocks 10 will move laterally closer to each other until the ends of the two locking rods 9 that are away from each other enter the two through openings respectively. At this time, the top of the milling cutter 5 is controlled to abut against the lower surface of the mounting block 6, and the two locking openings 8 are respectively corresponding to the positions of the two locking rods 9, and then the spring rod 11 is released, and the moving plate 12 will move in the spring. The rod 11 quickly moves and resets under the elastic potential energy of the rod 11, and the two pressing rods 13 also quickly moves and resets to enter the straight opening 21, and the pressing force applied to the two moving blocks 10 disappears. The two moving blocks 10 will quickly move and reset with the two locking rods 9 respectively under the elastic potential energy of the two telescopic springs 16, and the ends of the two locking rods 9 will respectively pass through the two locking openings 8, thereby completing the installation of the milling cutter 5. When the milling cutter 5 needs to be disassembled, the spring rod 11 is controlled to contract, so that the two moving blocks 10 respectively bring the two locking rods 9 close to each other, until the ends of the two locking rods 9 are respectively moved out of the two locking openings 8, the installation of the milling cutter 5 can be released, which is convenient and quick.

[0026] A push plate 17 is fixedly mounted on one end of the spring rod 11, and a surface of the push plate 17 is provided with anti-slip grooves;

[0027] The spring rod 11 can be extended or retracted by controlling the push plate 17 to move, and the anti-slip pattern can increase the friction between the contact surface of the palm and the push plate 17 .

[0028] A limiting assembly is provided on the surface of the mounting block 6, and the limiting assembly is used to limit the contraction of the spring rod 11. The limiting assembly includes a rotating shaft 18 and an L-shaped limiting plate 19 fixedly sleeved on the rotating shaft 18. A fixing block is fixedly installed on the surface of the mounting block 6, and a rotating opening is opened on the surface of the fixing block. The rotating shaft 18 is rotatably installed in the rotating opening. A rotating block is fixedly installed at one end of the rotating shaft 18. A torsion spring 20 is sleeved on the rotating shaft 18, and the two ends of the torsion spring 20 are respectively fixedly connected to the rotating block and the fixed block. The end of the limiting plate 19 away from the rotating shaft 18 is against the surface of the push plate 17 close to the mounting block 6;

[0029] When the installation of the milling cutter 5 is completed, the end of the limiting plate 19 away from the rotating shaft 18 will abut against the surface of the push plate 17 close to the mounting block 6 under the elastic potential energy of the torsion spring 20, thereby limiting the movement of the push plate 17 in the direction close to the mounting block 6 and limiting the contraction of the spring rod 11, thus playing a safety role;

[0030] When the milling cutter 5 needs to be disassembled, the rotating shaft 18 is first controlled to rotate so that the end of the limiting plate 19 no longer abuts against the surface of the push plate 17, and then the push plate 17 can be controlled to move and the spring rod 11 can be controlled to contract.

[0031] In the present invention, when the milling cutter 5 needs to be installed, the two pressing rods 13 are first moved by controlling the spring rod 11 to contract. During the movement, the bottom ends of the two pressing rods 13 will enter the two oblique openings 14 from the two straight openings 21 respectively, and the bottom end surfaces of the pressing rods 13 will abut against the walls of the oblique openings 14. Under the pressure of the two pressing rods 13, the two moving blocks 10 will move laterally closer to each other until the ends of the two locking rods 9 that are away from each other enter the two through openings respectively. At this time, the top of the milling cutter 5 is controlled to abut against the lower surface of the mounting block 6, and the two locking openings 8 are respectively corresponding to the positions of the two locking rods 9, and then the spring rod 11 is released, and the moving plate 12 is moved. It will quickly move and reset under the elastic potential energy of the spring rod 11, and the two pressure rods 13 will also quickly move and reset to enter the straight opening 21, and the pressure force applied to the two moving blocks 10 will disappear. The two moving blocks 10 will quickly move and reset with the two locking rods 9 respectively under the elastic potential energy of the telescopic component, and the ends of the two locking rods 9 will respectively pass through the two locking openings 8, thereby completing the installation of the milling cutter 5. When the milling cutter 5 needs to be disassembled, the spring rod 11 is controlled to contract, so that the two moving blocks 10 respectively bring the two locking rods 9 close to each other, until the ends of the two locking rods 9 are respectively moved out of the two locking openings 8, the installation of the milling cutter 5 can be released, which is convenient and quick.
