Problems solved by technology
Because the clamping and positioning of the automobile cantilever frame is difficult, it is difficult for traditional cutting equipment to achieve such a high cutting accuracy. Therefore, enterprises have always used laser cutting for processing. The cost of laser cutting is high, resulting in high production costs for parts.

The invention discloses a sawing machine used for cutting automobile cantilever support. The sawing machine comprises a machine stand, wherein a mounting base is arranged on the machine stand; a floor stand is arranged on the machine stand; a movable base capable of sliding up and down and an upper hydraulic cylinder for driving the movable base are arranged on the floor stand; a saw blade is arranged on the movable base in a rotary mode; a main motor for driving the saw blade to rotate through a transmission device is arranged on the machine stand; a mounting rack is arranged on the mounting base; an upper clamping hydraulic cylinder is arranged on the mounting rack; an upper clamping base is arranged on the end part of the piston rod of the upper clamping hydraulic cylinder; two upper positioning blocks are arranged on the upper clamping base; a lower clamping base is arranged on a position, corresponding to the upper clamping base, of the mounting base; two lower positioning blocks are arranged on the lower clamping base; a side positioning rack for positioning a middle straight section of the automobile cantilever support is arranged on the mounting base; two side positioning blocks are arranged on the side positioning rack; a side pressing hydraulic cylinder which is matched with the opposite side positioning rack is arranged on the mounting base; and a middle pressure block is arranged on the end part of the piston rod of the side pressing hydraulic cylinder. The sawing machine can be used for precisely cutting the automobile cantilever support.
Description
technical field [0001] The invention relates to a pipe material processing equipment, in particular to a sawing machine used for cutting automobile cantilever frames. Background technique [0002] car cantilever Figure 1-2 As shown, it includes end bending section, arc connecting section, middle straight section and tail section. After the automobile cantilever frame is stamped and formed, it is necessary to cut the end face of the tail section. The cutting requirements are very strict. The distance accuracy from the center of the cutting surface along the width direction and length direction of the cantilever frame to the center of the installation connection hole on the bending section at the end must reach 0.1mm, the flatness of the cutting surface needs to reach 0.5mm. Because the clamping and positioning of the automobile cantilever frame is difficult, it is difficult for traditional cutting equipment to achieve such a high cutting accuracy. Therefore, enterprises hav...
