In order to realize the drawing and conveying of the profile, a further technical scheme may be that a second clamping mechanism 8 is further arranged on the base 41, and when the base 41 moves, the second clamping mechanism 8 can be driven to move; the second clamping mechanism 8 is arranged for clamping the profile and dragging the profile to a designated cutting position when the base 41 moves, and the laser cutting mechanism 6 is arranged for performing groove cutting on the profile under the driving of the base 41 after the second clamping mechanism 8 releases the profile.

The base 41 is a member capable of moving back and forth left and right, and can be used for carrying the first clamping mechanism 5, the laser cutting mechanism 6 and the second clamping mechanism 8, and can carry the above members to move back and forth left and right (i.e., to move back and forth along the X-axis direction). It is understood that the plurality of mechanisms disposed on the base 41 share the base driving motor 43 to realize the movement in the left-right direction, which greatly reduces the number of driving motors compared with the prior art, i.e. is beneficial to reducing the manufacturing cost of the cutting machine, and also can reduce the volume of the cutting machine. On the other hand, the base 41 provides a uniform and stable installation basis for the first clamping mechanism 5, the laser cutting mechanism 6 and the second clamping mechanism 8, and machining references are uniform, which is beneficial to simplifying installation and debugging procedures of each mechanism and improving cutting machining precision.

The laser cutting mechanism 6 is a member for cutting a profile, and the laser cutting mechanism 6 can move relative to the profile under the driving of the base 41, so as to cut a strip-shaped groove on the profile. Of course, the movement of the base 41 relative to the profile is carried out on the premise that the profile is not clamped by the components arranged on the base 41 on the one hand, and on the other hand is clamped by the fixing components (such as the rotating chuck 3 or other fixing clamps) outside the profile groove cutting device 4.

Further, as shown in fig. 1 and 2, the laser cutting mechanism 6 includes a cross arm 61, a vertical arm 62 and a laser cutting head 63, the cross arm 61 is fixedly connected to the base 41 and is transversely arranged perpendicular to the moving direction of the base 41, where the arrangement direction of the cross arm 61 is defined as the Y-axis direction; the vertical arm 62 is vertically arranged and perpendicular to the moving direction of the cross arm 61 and the base 41, the arrangement direction of the vertical arm 62 is defined as a Z-axis direction, the vertical arm 62 is movably connected to the cross arm 61 and can move back and forth along the extending direction (Y-axis direction) of the cross arm 61, the laser cutting head 63 is movably connected to the vertical arm 62 and can move back and forth along the extending direction (Z-axis direction) of the vertical arm 62, and X, Y and the Z-axis form three-dimensional coordinate axes which are arranged perpendicularly to each other.

As shown in fig. 4, the first clamping mechanism 5 is a member capable of being clamped onto the profile, the first clamping mechanism 5 includes at least a pair of first clamping arms 51 and a first driving device 52, the first driving device 52 is used for driving the first clamping arms 51 to open or clamp, the pair of first clamping arms 51 forms a clamping opening of the first clamping mechanism 5, and the rolling member 7 is disposed on the first clamping arms 51 and arranged towards the clamping opening; due to the arrangement of the rolling members 7 at their nip, the first clamping means 5 can be moved back and forth along the profile without moving the profile while clamping or clasping the profile in a state where the profile is clamped by other members, such as the rotating chuck 3. I.e. the first clamping means 5 are intended to limit the movement of the profile in its radial direction and not in its axial direction; if the first clamping means 5 is arranged near the laser cutting means 6, this provides a stable support for the profile near the cutting position, which well limits the swing of the profile in the radial direction thereof, which is beneficial to ensure the stability of the profile during cutting and thus greatly improves the cutting accuracy. On the other hand, because the first clamping mechanism 5 moves along with the laser cutting mechanism 6, there is no need to worry about the clamping support mechanism blocking the movement of the laser cutting mechanism 6, the laser cutting mechanism 6 can also conveniently cut the tail end of the section bar, and the problem that the tail end of the long-strip section bar cannot be cut in the prior art is well solved.

As shown in fig. 2 and 4, the rolling member 7 is a member arranged on the first clamping mechanism 5 for snugly embracing the profile, the rolling member 7 includes a roller bracket 73, a rotating shaft 72 and a roller 71, the roller bracket 73 is connected to the first clamping arm 51 of the first clamping mechanism 5, the rotating shaft 72 is connected to the roller bracket 73, and the roller 71 is mounted on the rotating shaft 72 in a rolling manner. The roller brackets 73 are linearly arranged along the left-right direction, at least two rollers 71 are arranged on the same roller bracket 73, as shown in fig. 5, 4 rollers 71 are arranged on the roller brackets 73, and the rollers 71 can roll back and forth along the two side surfaces of the profile after being clamped on the profile. Of course, the roller 71 may be replaced by a ball as an equivalent embodiment.

As shown in fig. 5, the second clamping mechanism 8 includes at least one pair of second clamping arms 81 and a second driving device 82, and the first driving device 52 is used for driving the second clamping arms 81 to open or clamp. The second clamping mechanism 8 is a member for clamping the profile, and the second clamping mechanism 8 shares the driving mechanism of the base 41 to move back and forth left and right so as to draw the profile to a specified cutting position, so that compared with the prior art, the manufacturing cost is effectively reduced, and the size of the cutting machine is reduced. Of course, when the profile is rotated or slot cut, the second clamping means 8 is in an open position to ensure that the profile is movable.

In order to ensure that the two clamping mechanisms can clamp the profile, a further technical scheme can be that the clamping center lines of the first clamping mechanism 5, the second clamping mechanism 8 and the rotating chuck 3 are overlapped. Therefore, the first clamping mechanism 5 or the second clamping mechanism 8 can be accurately and stably clamped on the section bar, so that the drawing and feeding or the rolling along the section bar are realized, meanwhile, two ends of the section bar can be stably supported, and the cutting precision is improved.
