The utility model has a simple structure and an ingenious design. When cutting an aluminum profile at a forty-five-degree angle, the second limiting mechanism is released, the connecting rod 10 is rotated to rotate the second limiting block 11 to the top of the aluminum profile to be cut, and then the second limiting mechanism is used to limit the sliding sleeve 9, and the electric push 7 is controlled to extend so that the second limiting block 11 can respectively press the aluminum profiles on both sides of the cutting groove 3. At this time, cutting can prevent the occurrence of material collapse, saves manpower, can meet market demand, and is suitable for promotion. When using the utility model, first, when cutting an aluminum profile with an angle of ninety degrees, the aluminum profile is placed on the first limiting mechanism, and at the same time, it is made to be ninety degrees with the plane where the cutting device is located. At this time, the connecting rod 10 is in a vertical position, and the electric push rod 7 is controlled to extend. The first limiting block 8 and the second limiting block 11 can simultaneously press and position the aluminum profile; when it is necessary to cut an aluminum profile with an angle of forty-five degrees, the aluminum profile is made to be forty-five degrees with the plane where the cutting device is located, the second limiting mechanism is released, and the sleeve 9 is pressed downward, and the spring 12 is compressed. At this time, the connecting rod 10 is rotated to make the second limiting block 11 rotate to the top of the aluminum profile, and the second limiting mechanism is used to limit the sleeve 9 to prevent the sleeve 9 from rotating. At this time, the electric push rod 7 is controlled to extend so that the second limiting block 11 presses the aluminum profile, and the cutting device is started again for cutting.
[0017] Specifically, if Figure 2As shown in the figure, the cutting device in this embodiment includes a cutting blade 20. A rotating shaft 21 is rotatably installed on the workbench 1. A bearing seat is rotatably provided on the outer periphery of the rotating shaft 21. The outer periphery of the bearing seat is fixedly installed at the bottom of the workbench 1 through a first connecting rod. One end of the rotating shaft 21 is fixedly installed with a first motor 23 through a second connecting rod 22. A cutting blade 20 is fixedly installed on the rotating shaft of the first motor 23. The rotating shaft of the first motor 23 is coaxially arranged with the cutting blade 20. A driving mechanism for driving the rotating shaft 21 to rotate is provided on the workbench 1. The cutting blade 20 can pass through the cutting through slot 3 to cut the aluminum profile. Control the rotating shaft of the first motor 23 to drive the cutting blade 20 to rotate, and drive the rotating shaft 21 to rotate through the driving mechanism. The rotation of the rotating shaft 21 can drive the second connecting rod 22 and the first motor 23 to rotate, so as to drive the cutting blade 20 to pass through the cutting through slot 3 to cut the aluminum profile above.
[0018] Specifically, as shown in the figure, the driving mechanism in this embodiment includes a second motor 30. The second motor 30 is fixedly installed on the workbench 1. A coaxial worm 31 is fixedly installed on the rotating shaft of the second motor 30. The worm 31 is rotatably installed on the support leg 2 through a bearing seat. The outer periphery of the bearing seat is fixedly installed on the support leg 2 through a fourth connecting rod. A worm gear 32 is meshed and cooperated with one side of the worm 31. The worm gear 32 is fixedly installed on the rotating shaft 21 and is coaxially arranged. Control the rotating shaft of the second motor 30 to drive the worm 31 to rotate. The worm 31 drives the worm gear 32 to rotate, and the worm gear 32 can drive the rotating shaft 21 to rotate.
[0019] Further, as Figure 2As shown in the figure, the first limiting mechanism in this embodiment includes a first baffle 40 and a second baffle 41. The first baffle 40 is a rectangular plate, and the second baffle 41 is a trapezoidal plate. The included angle between the inclined surface provided on the second baffle 41 and the cutting through groove 3 is 45 degrees. There is a sliding contact fit between the first baffle 40 and the second baffle 41, between the first baffle 40 and the groove 4, and between the second baffle 41 and the groove 4. The first baffle 40 and the second baffle 41 can close the groove 4. A plurality of through grooves 42 are respectively opened in the groove 4. Fixing rods 43 are respectively slidably fitted in the through grooves 42. Blocks 44 are respectively provided at one ends of the fixing rods 43, and the other ends of the fixing rods 43 are respectively fixedly installed on the corresponding first baffle 40 or second baffle 41. The first baffle 40 and the second baffle 41 are respectively elastically connected to the bottom of the groove 4 through a plurality of first springs 45. The first springs 45 are sleeved on the outer circumference of the fixing rods 43. One end of the first spring 45 is fixedly installed at the bottom of the groove 4, and the other end of the first spring 45 is respectively fixedly installed on the corresponding first baffle 40 or second baffle 41. In the initial state, the horizontal height of the first baffle 40 is greater than the horizontal height of the second baffle 41, and the horizontal height of the second baffle 41 is greater than the horizontal height of the workbench 1. There is a height difference between the first baffle 40, the second baffle 41 and the workbench 1, so that one side of the aluminum profile can abut against the outer side wall of the first baffle 40 or the second baffle 41, thereby restricting the movement of the aluminum profile and facilitating the positioning of the aluminum profile. When it is necessary to perform a 45-degree cut on the middle of the aluminum profile, press the first baffle 40 and the second baffle 41 at the rear to make them at the same horizontal position as the workbench 1. The first spring 45 is compressed, and the fixing rod 43 moves downward. At this time, press the aluminum profile and place it on the workbench 1, and use the inclined surface of the second baffle 41 with a raised front side to limit one side of the aluminum profile, and then the middle position of the aluminum profile can be cut. The first baffle 40 and the second baffle 41 at the rear will not cause obstruction, solving the problem that only the end of the aluminum profile can be cut in the prior art. The block 44 can prevent the fixing rod 43 from moving out of the through groove 42.
[0020] Furthermore, as shown in the figure, the second limiting mechanism in this embodiment includes an annular plate 50. The annular plate 50 is fixedly installed at one end of the electric push rod 7 and is coaxially arranged. A plurality of groups of insertion holes 51 are provided on the annular plate 50. Each group has two insertion holes 51 and is centrosymmetric about the center of the annular plate 50. A group of insertion rods 52 are fixedly installed on the sliding sleeve 9. Each group of insertion holes 51 can be inserted and matched with the insertion rods 52. Two insertion rods 52 are provided for the insertion and matching of each group of insertion holes 51. By pressing the sliding sleeve 9, the insertion rods 52 are removed from the insertion holes 51. At this time, the connecting rod 10 can be rotated. When rotated to a suitable position and the insertion rods 52 are inserted into the corresponding group of insertion holes 51, the sliding sleeve 9 can be limited again.
[0021] Further, as shown in the figure, the angle range of rotation of the connecting rod 10 in this embodiment is a. The first limiting block 8 can press the aluminum profile on the second baffle 41, and the second limiting block 11 can press the aluminum profile on the workbench 1. When the connecting rod 10 rotates to the vertical state, at this time, the first limiting block 8 and the second limiting block 11 simultaneously press and limit the aluminum profile placed on the second baffle 41; when the connecting rod 10 rotates to the horizontal state or continues to rotate by a certain angle, the first limiting block 8 presses and limits the aluminum profile on the second baffle 41, and the second limiting block 11 presses and limits the aluminum profile on the workbench 1.
