Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 and 2, a vertical band sawing machine includes a bed 1, a saw frame 8 on the bed 1, a first chuck 10 and a second chuck 5, the first chuck 10 and the second chuck 5. The second chuck 5 is respectively located on the left and right sides of the saw frame 8; the bed 1 is provided with four longitudinal guide rails 6 which are respectively laid in parallel along the longitudinal direction of the bed; Horizontal guide rail base 12, three horizontal guide rails 9 vertical to the vertical guide rail 6 are laid in parallel on the horizontal guide rail base 12; 8 is provided with a rotating guide head 7 that can rotate thereon, and the rotating guide head can rotate 180 degrees, thereby changing the cutting direction of the band saw blade.

The second chuck 5 is arranged on the longitudinal guide rail 6 and is in sliding fit with the longitudinal guide rail 6 .

The second chuck 5 is arranged on the chuck seat 3, and the rear end of the rotating shaft of the second chuck 5 is provided with a locking disc 4 for fixing the second chuck; the chuck seat 3 is equipped with a fixed locking disc 4 locking device 15; the chuck base 3 is set on the longitudinal guide rail 6, and is in sliding fit with the longitudinal guide rail 6; the workpiece clamping cylinder 2 is connected to the chuck base 3, and the workpiece clamping cylinder is installed on bed 1. The workpiece tightening oil cylinder 2 can drive the chuck seat to move on the longitudinal guide rail, thereby driving the second chuck 5 to move, and adjusting the distance between the second chuck 5 and the first chuck 10 .

The sliding fit of the transverse guide rail base 12 and the longitudinal guide rail 6 is slidably connected with the longitudinal guide rail 6 through a plurality of matching sliders fixed on the bottom surface of the transverse guide rail base 12; the sliding fit of the saw frame 8 and the transverse guide rail 9 is through its A plurality of cooperating slide blocks fixed on the bottom surface are slidably connected with the transverse guide rail 9 . The throat depth direction of the saw frame 8 is perpendicular to the longitudinal guide rail 6 .

The first chuck 10 is in transmission connection with a motor 11 provided on the base of the first chuck. The motor 11 drives the first chuck 10 to rotate, thereby driving the workpiece clamped by the first chuck 10 and the second chuck 5 to rotate.

And the saw frame 8 can also follow the transverse guide rail 9 and move longitudinally along the bed 1 on the longitudinal guide rail 6 . Therefore, the saw frame 8 can perform longitudinal sawing and transverse sawing to the workpiece. The saw frame 8 is also provided with two rotating guide heads 7 that can rotate 180 degrees, which can drive the band saw blade to change the cutting direction. The rotary steerable head 7 is a prior art and will not be described in detail here. The second chuck 5 is arranged on the chuck seat 3, and is provided with a locking plate 4 for locking the second chuck 5; the chuck seat 3 is arranged on the longitudinal guide rail 6, and is in a sliding fit with the longitudinal guide rail 6 ; The chuck seat 3 is connected with the workpiece top tight oil cylinder 2, and the workpiece top tight oil cylinder 2 is installed on the bed 1.
