During installation, first that the sliding edge of the first roller 7-3 of the first roll wheel assembly and curvilinear guide 2 one sides is chimeric, then open clamping cylinder control valve 7-9, give the air inlet air feed of clamping cylinder 7-1 near contiguous block 7-8, under the effect of high pressure gas, clamping cylinder piston rod 7-6 is to the contiguous block 7-8 that pulls back, thereby by contiguous block 7-8, drive the second roller shaft 7-4 to move to close the first roller shaft 7-2 direction along the stroke groove of two way block 7-7, make the sliding edge of the second roller 7-5 and curvilinear guide 2 opposite sides chimeric; During dismounting, stop the air inlet air feed near contiguous block 7-8 to clamping cylinder 7-1, while is the air inlet air feed away from contiguous block 7-8 to clamping cylinder 7-1, clamping cylinder piston rod 7-6 promotes forward contiguous block 7-8, thereby by contiguous block 7-8, drive the second roller shaft 7-4 along the stroke groove of two way block 7-7 to moving away from the first roller shaft 7-2 direction, just make the sliding edge of the second roller 7-5 and curvilinear guide 2 throw off.
The operation principle of cutting machine of the present invention is:
1) installation process
By cutting power head member towards airframe parts, first by the first all roller 7-3 and curvilinear guide 2 one Slideslip edge phase embeddings, and adjustment makes base 1 and curvilinear guide 2 almost parallels, control clamping cylinder control valve 7-9, make the clamping cylinder piston rod 7-6 of clamping cylinder 7-1 to the contiguous block 7-8 that pulls back, contiguous block 7-8 drives the second roll wheel assembly to move to the first roll wheel assembly direction, make the second roller 7-5 with curvilinear guide 2 opposite side sliding edges along phase embedding, complete the location of cutter sweep on curvilinear guide 2.Mesh control cylinder control valve 6-12 again, the engagement cylinder piston rod 6-7 that makes to mesh cylinder 6-1 drives the boss 6-9 direction of slide 6-2 on along guide post 6-3 to curvilinear guide 2 to move, and makes sprocket wheel 6-6 and the chain 6-8 engagement being arranged on boss 6-9.
2) cutting process
Feeler block is adsorbed on face type frame flat board, shake course adjusting handle 4-3, make the moving guide rail 4-2 of dovetail drive cutting power head member along the rectangular dovetail projection linear longitudinal movement of the quiet guide rail 4-1 of dovetail, when the saw blade 3-1 of cutting power head member and tool setting plane contact, stop shaking course adjusting handle 4-3, screw course lock-screw 4-4, moving guide rail 4-2 is motionless for dovetail, completes course and regulates.Open power motor control valve 3-5, pneumatic power motor 3-2 drives saw blade 3-1 rotation, slowly shake radial feed handwheel 5-3, square moving guide rail 5-1 drives the radial motion of cutting power head member, saw blade 5 is slowly cut covering, saw blade 5 penetraction depths reach 7mm left and right and stop shaking radial feed handwheel 5-3, screw radially lock-screw 5-5, square moving guide rail 5-1 stop motion.Finally feeding motor control valve 6-13 joystick is beaten to shelves left, pneumatic feeding motor 6-4 band movable sprocket 6-6 turns clockwise, and drives cutter sweep along curvilinear guide 2 circulatory motions, realizes annular cutting.
3) unloading process
When cutter sweep cuts after one week along curvilinear guide 2, airframe parts covering surplus has been cut.Now, feeding motor control valve 6-13 joystick is beaten to middle-grade, pneumatic feeding motor 6-4 stops operating, and sprocket wheel 6-6 stops operating, and whole cutter sweep is slack; Power motor control valve 3-5 is closed, pneumatic power motor 3-2 stops operating again, and saw blade 3-1 stops cutting; Unclamp radially lock-screw 5-5, oppositely shake radial feed handwheel 5-3 cutting power head member is return; Mesh control cylinder control valve 6-12, engagement cylinder piston rod 6-7 promotes slide 6-2, and sprocket wheel 6-6 is moved to the direction away from chain 6-8, and sprocket wheel 6-6 and chain 6-8 throw off; Control clamping cylinder control valve 7-9, clamping cylinder piston rod 7-6 pushes away forward the second roll wheel assembly again, and the second roller 7-5 and curvilinear guide 2 are thrown off, and finally takes off cutter sweep.
