DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in 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 in 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.
[0022] See also Figures 1 to 4 The utility model provides a technical solution: a fixed workpiece structure of a pneumatic angle trimming machine, including a workbench 1, a fixed plate 2 is provided at the bottom of the workbench 1, the top corner of the fixed plate 2 is fixed to the bottom of the workbench 1 by a connecting rod, and the top of the fixed plate 2 is connected to a fixed seat 15 through an adjustment mechanism, a cutter 5 is rotatably connected to one side of the fixed seat 15, one end of the cutter 5 is connected to a motor 16, and the motor 16 is fixed to the fixed seat 15, a cutting groove 13 is opened at the top of the workbench 1, and the top of the cutter 5 passes through the cutting groove 13 and extends above the workbench 1. The cutter 5 can be driven to rotate by the motor 16, and at the same time, the cutter 5 can be driven to move along the cutting groove 13 by the adjustment mechanism to perform angle trimming on the workpiece placed on the workbench 1;
[0023] like Figure 3 As shown, the top of the workbench 1 is rotatably connected to the two sides of the cutting groove 13 with a rotating shaft 21, the top of the rotating shaft 21 is connected to a strip positioning plate 6, the bottom of the strip positioning plate 6 is in contact with the top of the workbench 1, and the top of each strip positioning plate 6 is connected to a clamping mechanism. During use, the workpiece to be cut can be placed on the workbench 1 so that one side of the workpiece is in contact with the side of the strip positioning plate 6, the workpiece is positioned, and then the workpiece is fixed by the clamping mechanism, and then the cutter 5 is used to cut the angle.
[0024] like Figure 1 and Figure 3As shown, the top of the workbench 1 is provided with an arc groove 7 at one end of the strip positioning plate 6 away from the rotating shaft 21, and the arc groove 7 is coaxially arranged with the rotating shaft 21. An adjusting screw 8 is arranged in each arc groove 7, and a through hole 23 is provided at one end of each strip positioning plate 6 away from the rotating shaft 21. The top of the adjusting screw 8 slides through the corresponding through hole 23, and a locking screw sleeve 9 is sleeved on the side of each adjusting screw 8. The locking screw sleeve 9 is threadedly matched with the adjusting screw 8, and the bottom of the locking screw sleeve 9 is in contact with the top of the strip positioning plate 6. In actual use, when it is necessary to adjust the full angle of the workpiece, the staff can loosen the locking screw sleeve 9, and then rotate the strip positioning plate 6 along the rotating shaft 21, and the adjusting screw 8 moves along the arc groove 7. When it is adjusted to the specified angle, the staff can tighten the locking screw sleeve 9, and the strip positioning plate 6 and the workbench 1 can be fixed to complete the angle adjustment.
[0025] When the workpiece is in working order, the operator first rotates the locking screw sleeve 9 in the opposite direction to loosen the locking screw sleeve 9, and then moves the adjusting screw 8 along the direction of the arc groove 7 to make the strip positioning plate 6 rotate along the rotating shaft 21, so as to adjust the rotation angle of the strip positioning plate 6. When the rotation angle of the strip positioning plate 6 is the same as the full angle angle of the workpiece to be processed, the rotation of the strip positioning plate 6 is stopped, and the locking screw sleeve 9 is rotated so that the bottom of the locking screw sleeve 9 is tightly in contact with the top of the strip positioning plate 6 to complete the fixation of the strip positioning plate 6. Then, the workpiece to be processed is placed on the workbench 1, and one side of the workpiece is in contact with the side of the strip positioning plate 6, and the part to be cut of the workpiece is aligned with the cutter 5. Then, the cutter 5 is driven to rotate by the motor 16, and the cutter 5 is driven to move along the cutting groove 13 by the adjusting mechanism to cut the workpiece to complete the full angle of the workpiece, and the cutter 5 is restored to its original position by the adjusting mechanism after cutting.
[0026] Further, such as Figure 2 As shown, the adjustment mechanism includes a slider 20 fixed to the bottom of the fixed seat 15, a connecting plate 17 is extended from the top end of the slider 20, a mounting frame 19 is installed at the top end of the fixed plate 2, a cylinder 18 is installed on the side of the mounting frame 19, and the other end of the cylinder 18 passes through the mounting frame 19 and is fixed on the connecting plate 17. When in use, the cylinder 18 extends to push the slider 20 to move, and the slider 20 can drive the cutter 5 to move along the direction of the cutting groove 13 to cut the workpiece. After the cutting is completed, the cylinder 18 is controlled to retract to restore the cutter 5 to its original position.
[0027] Further, such as Figure 2 As shown, two parallel guide rails 14 are installed on the top of the fixed plate 2, and the slider 20 is sleeved on the guide rails 14 and slidably cooperates with the guide rails 14. Under the cooperation of the guide rails 14 and the slider 20, the cutter 5 can be limited to avoid the cutter 5 from deviating during the cutting process.
[0028] Further, such as Figure 3 As shown, a limit plate 3 is installed at the bottom of each adjusting screw 8, and the top of the limit plate 3 contacts the bottom of the workbench 1. When fixing the strip positioning plate 6, the adjusting screw 8 can be moved upward by rotating the locking screw sleeve 9, and the top of the limit plate 3 contacts the bottom of the workbench 1 tightly. At the same time, the bottom of the locking screw sleeve 9 contacts the top of the strip positioning plate 6 tightly, so that the strip positioning plate 6 and the workbench 1 can be fixed together, and the fixing is convenient;
[0029] like Figure 3 As shown, at least one limiting groove 22 is formed on the side of each adjusting screw 8, and at least one limiting block 24 is installed on the inner surface of each through hole 23, and the other end of each limiting block 24 extends into the limiting groove 22. With the cooperation of the limiting block 24 and the limiting groove 22, the adjusting screw 8 can be limited to prevent the adjusting screw 8 from rotating with the locking screw sleeve 9 when the locking screw sleeve 9 is rotated.
[0030] Further, such as Figure 3 As shown, the clamping mechanism includes a screw rod 10 rotatably connected to the top of the strip positioning plate 6, each screw rod 10 is sleeved with a U-shaped pressing plate 11, and both ends of the U-shaped pressing plate 11 extend to one side of the strip positioning plate 6. When fixing the workpiece, the height of the U-shaped pressing plate 11 can be adjusted by rotating the screw rod 10, so that the bottom of the U-shaped pressing plate 11 can be tightly pressed on the workpiece to fix the workpiece;
[0031] like Figure 3 As shown, two guide rods 12 are symmetrically mounted on the top of each strip positioning plate 6, and the top of each guide rod 12 slides through the U-shaped pressing plate 11. The U-shaped pressing plate 11 can be limited by the guide rods 12 to prevent the U-shaped pressing plate 11 from rotating with the screw rod 10.
[0032] Furthermore, Figure 1 As shown, a protective cover 4 is installed on the top of the workbench 1 at one end of the cutting groove 13. When the cutter 5 moves to one end of the cutting groove 13, the protective cover 4 covers the cutter 5. After the cutting is completed, the cylinder 18 contracts and the cutter 5 can be moved into the protective cover 4 to isolate the cutter 5 from the external environment to prevent the staff from being accidentally touched and injured.
