As shown in fig. 1, the lifting mechanism 4 includes a connecting rod 41 and a lifting cylinder 43, a vertical fixing frame 11 is fixedly disposed above the machine frame 1, a middle portion of the connecting rod 41 is hinged to the fixing frame 11 through a horizontal shaft, the motor 2 is fixed to one end of the connecting rod 41 above the workpiece 6, and a cylinder body and a telescopic rod of the lifting cylinder 43 are hinged to one ends of the machine frame 1 and the connecting rod 41 far away from the motor 2. The lifting cylinder 43 is started to extend out, and the lifting cylinder 43 drives the connecting rod 41 to rotate, so that the motor 2 and the cutting blade 3 are driven to move downwards to cut the workpiece 6. Of course, other lifting structures are also possible, and only the cutting blade 3 and the motor 2 need to be driven to lift to cut the workpiece 6.

As shown in fig. 1, the positioning structure 5 includes a horizontal table 51, a first positioning column 52, a second positioning column 53, a first clamping cylinder 54 and a second clamping cylinder 55, the horizontal table 51 is erected above the frame 1 and located on one side of the frame 1, the first positioning column 52 and the second positioning column 53 are vertically fixed on the upper surface of the horizontal table 51, the first positioning column 52 and the second positioning column 53 are respectively located on two sides of the workpiece 6 and respectively located at the head end and the tail end of the workpiece 6, and the first clamping cylinder 54 and the second clamping cylinder 55 clamp the workpiece 6 correspondingly to the first positioning column 52 and the second positioning column 53 respectively. The workpiece 6 is placed above the horizontal table 51, the two sides of the workpiece 6 are respectively attached to the first positioning column 52 and the second positioning column 53, the first clamping cylinder 54 and the second clamping cylinder 55 are started to be matched with the first positioning column 52 and the second positioning column 53 to clamp and fix the workpiece 6, the workpiece 6 is guaranteed to be fixed in a cutting process, only the workpiece 6 needs to be attached to the first positioning column 52 and the second positioning column 53, and the adaptation degree of different workpieces 6 is improved.

As shown in fig. 1, a pressure plate 57 is fixedly provided at an end of the expansion link of the first clamp cylinder 54 and the second clamp cylinder 55, and rubber is fixedly provided outside the pressure plate 57. When the first clamping cylinder and the second clamping cylinder clamp the workpiece 6, the rubber can increase the contact area of the pressing plate 57 and the workpiece 6 when the pressing plate 57 contacts the workpiece 6 by utilizing the deformability of the rubber, so that the stability of clamping the workpiece 6 can be increased and the possibility of damaging the workpiece 6 can be reduced.

Regarding the workpiece 6, the two-point contact positioning using only the first positioning column 52 and the second positioning column 53 can actually position a plurality of workpieces 6 of different specifications with high efficiency, but the positioning stability and consistency are not consistent, so that it is difficult to control the consistency of the machined workpieces 6, and most of them still need to be determined empirically. Therefore, as shown in fig. 2, an auxiliary positioning mechanism 56 may be disposed on the horizontal table 51, the auxiliary positioning mechanism 56 includes two auxiliary positioning posts 561 disposed vertically, and the two auxiliary positioning posts 561 are respectively disposed on two sides of the workpiece 6.

For workpieces 6 with different specifications, the positions of the two auxiliary positioning columns 561 should be adjustable, so as to adapt to workpieces 6 with different curves and lengths, otherwise, the workpieces 6 are difficult to position. Therefore, as shown in fig. 2, the auxiliary positioning mechanism 56 further includes a support frame and two lead screws 563, the support frame is formed by the horizontal platform 51, the horizontal platform 51 is hollow at the lead screws 563, the two lead screws 563 are arranged in parallel and rotatably connected with the horizontal platform 51, two sliding slots 511 are opened on the horizontal platform 51, the two auxiliary positioning posts 561 are respectively and independently screwed with the two lead screws 563, and the upper ends of the auxiliary positioning posts 561 penetrate out of the sliding slots 511. The screw rod 563 is rotated, and the screw rod 563 drives the auxiliary positioning column 561 to slide in the sliding groove, so that the positions of the two auxiliary positioning columns 561 are changed, and the adaptation degree of different workpieces 6 is improved.

In addition, as shown in fig. 1, in order to control the cut length of the workpiece 6 to be consistent, it is preferable to provide a abutting block 512 on the horizontal table 51, where the abutting block 512 is located at one end of the horizontal table 51 far from the cutting blade 3, and the abutting block 512 can abut against one end of the limiting workpiece 6, so as to ensure that the workpiece 6 has a limiting reference during the placing process, and ensure the precision of the cutting position of the workpiece 6, that is, the consistency of the lengths of the workpiece 6.

Also, since many of the workpieces 6 are curved, the end surface of the workpiece 6 away from the cutting end may be beveled, and the workpiece 6 may be in line contact with the abutment block 512, so that the positioning of the workpiece 6 is less stable. Therefore, as shown in fig. 1, the abutting block 512 and the horizontal table 51 can be connected by vertical shaft rotation, an arc-shaped groove 513 using the abutting block 512 and the rotation shaft of the horizontal table 51 as a circle center is formed in the horizontal table 51, a fastening bolt 514 is arranged in the arc-shaped groove 513 from bottom to top in a penetrating manner, and the fastening bolt 514 is in threaded connection with the abutting block 512. When the tip that work piece 6 is close to butt piece 512 is the inclined plane, not hard up tight bolt 514, relative horizontal stand rotates butt piece 512, after the angle is suitable, makes the terminal surface that work piece 6 is close to butt piece 512 and the butt piece 512 laminating butt, screws up tight bolt 514 again, and it is fixed with horizontal stand 51 butt with butt piece 512 to promote the stability of work piece 6 location.

Finally, as shown in fig. 1, a side of the rack 1 far from the horizontal table 51 is set to be an inclined plane which is inclined outwards and arranged downwards, and a waste box 12 is placed below the inclined plane, so that the cut waste can slide down along the inclined plane of the rack 1 and is collected through the waste box 12, and the waste is prevented from being scattered randomly.
