The operation principle of annular infeed mean is; The gyration of sprocket wheel 6-6 is driven by pneumatic feeding motor 6-4, when sprocket wheel 6-6 and chain 6-8 will mesh, opens engagement cylinder control valve 6-12; Give engagement cylinder 6-1 ventilation; The engagement cylinder piston rod 6-7 pulling slide 6-2 of engagement cylinder 6-1 along guide post 6-3 backward straight line move, pneumatic feeding motor 6-4 and sprocket wheel 6-6 that slide 6-2 drives on it move to the direction near chain 6-8, mesh up to sprocket wheel 6-6 and chain 6-8; When sprocket wheel 6-6 and chain 6-8 need throw off; Close engagement cylinder control valve 6-12; Stop the ventilation to engagement cylinder 6-1, engagement cylinder piston rod 6-7 is sliding seat 6-2 forward just, slide 6-2 just along guide post 6-3 forward straight line move; Pneumatic feeding motor 6-4 and sprocket wheel 6-6 that slide 6-2 drives on it move to the direction away from chain 6-8, throw off up to sprocket wheel 6-6 and chain 6-8.Feeding motor control valve 6-13 is divided into three shelves in left, center, right, is screwed to left side shelves, and pneumatic feeding motor 6-4 drives sprocket wheel 6-6 and clockwise rotates, and is screwed to right shelves, and pneumatic feeding motor 6-4 drives sprocket wheel 6-6 and rotates counterclockwise, and is screwed to middle-gradely, and sprocket wheel 6-6 stops operating.When sprocket wheel 6-6 rotates along chain 6-8; All parts that the first roller 7-3 and the second roller 7-5 drive on base 1 and the base 1 move along curvilinear guide 2; Feeding motor control valve 6-13 control sprocket wheel 6-6 clockwise, counterclockwise or stop operating, drive afterwards on base 1 and the base 1 all parts forward, backward or stop motion.
As shown in Figure 5, the parts on base 1 and the base 1 pass through the track roller parts carry on curvilinear guide 2; The track roller parts comprise first roll wheel assembly, second roll wheel assembly and clamp cylinder 7-1; First roll wheel assembly comprises the first roller shaft 7-2 and is enclosed within the first roller 7-3 on the first roller shaft 7-2 that the first roller shaft 7-2 is fixed on base 1 lower surface; Second roll wheel assembly comprises the second roller shaft 7-4 and is enclosed within the second roller 7-5 on the second roller shaft 7-4; The first roller 7-3 and the second roller 7-5 are stuck on two sliding edges of curvilinear guide 2; One breach is arranged on the base 1, and the second roller shaft 7-4 passes this breach, and its upper end is higher than base 1; Clamp the upper surface that cylinder 7-1 is fixed on base 1, the clamping cylinder piston rod 7-6 that clamps cylinder 7-1 is fixedly connected with the upper end of the second roller shaft 7-4.The upper end that the second roller shaft 7-4 is higher than base 1 is " T " shape termination; Should be fixed with way block 7-7 respectively on the base 1 of both sides, " T " shape termination; Two way block 7-7 are provided with the stroke groove, and two transverse end of " T " shape termination are embedded in respectively in the stroke groove of two way block 7-7.Be fixed with contiguous block 7-8 on the upper surface of second roller shaft 7-4 upper end, the above-mentioned through hole that is provided with of contiguous block 7-8, clamping cylinder piston rod 7-6 passes this through hole and is fixedly connected with contiguous block 7-8.
During installation; Earlier that the sliding edge of the first roller 7-3 of first roll wheel assembly and curvilinear guide 2 one sides is chimeric; Open then and clamp cylinder control valve 7-9; Give and clamp the air inlet air feed of cylinder 7-1 near contiguous block 7-8; Under the effect of high pressure gas, clamp cylinder piston rod 7-6 to the contiguous block 7-8 that pulls back, thus through contiguous block 7-8 drive the second roller shaft 7-4 along the stroke groove of two way block 7-7 to moving near the first roller shaft 7-2 direction, make the sliding edge of the second roller 7-5 and curvilinear guide 2 opposite sides chimeric; During dismounting; Stop to clamping the air inlet air feed of cylinder 7-1 near contiguous block 7-8; Simultaneously to clamping the air inlet air feed of cylinder 7-1 away from contiguous block 7-8; Clamp cylinder piston rod 7-6 and promote contiguous block 7-8 forward, thus through 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 disengagement of the second roller 7-5 and curvilinear guide 2.
The operation principle of cutting machine of the present invention is:
1) installation process
With the cutting power head member towards the airframe parts; Earlier the first all roller 7-3 is breakked away with curvilinear guide 2 one and move edge embedding mutually; And adjustment makes base 1 and curvilinear guide 2 almost parallels; Control clamps cylinder control valve 7-9, makes the clamping cylinder piston rod 7-6 that clamps cylinder 7-1 to the contiguous block 7-8 that pulls back, and contiguous block 7-8 drives second roll wheel assembly and moves to the first roll wheel assembly direction; Make the second roller 7-5 and curvilinear guide 2 opposite side slip edge embeddings mutually, accomplish the location of cutter sweep on curvilinear guide 2.Control engagement cylinder control valve 6-12 makes the engagement cylinder piston rod 6-7 drive slide 6-2 of engagement cylinder 6-1 move along the boss 6-9 direction of guide post 6-3 on curvilinear guide 2 again, makes sprocket wheel 6-6 and the chain 6-8 engagement that is installed on the boss 6-9.
2) cutting process
Feeler block is adsorbed on the face type frame flat board; Shake course adjusting handle 4-3; Make the moving guide rail 4-2 of dovetail drive the rectangular dovetail projection linear longitudinal movement of cutting power head member along 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 to shake course adjusting handle 4-3, course lock-screw 4-4 screws; Moving guide rail 4-2 is motionless for dovetail, accomplishes the course and regulates.Open power motor control valve 3-5; Pneumatic power motor 3-2 drives saw blade 3-1 rotation, slowly shakes radial feed handwheel 5-3, and 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 and stop to shake radial feed handwheel 5-3 about 7mm, the radially lock-screw 5-5 that screws, square moving guide rail 5-1 stop motion.At last feeding motor control valve 6-13 joystick is beaten shelves left, pneumatic feeding motor 6-4 drives sprocket wheel 6-6 and turns clockwise, and drives cutter sweep along curvilinear guide 2 circulatory motions, realizes the annular cutting.
3) unloading process
After cutter sweep cut weeks along curvilinear guide 2, the cutting of airframe parts covering surplus was accomplished.At this moment, 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 the cutting power head member is return; Control engagement 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 clamps cylinder control valve 7-9 again, clamps cylinder piston rod 7-6 and pushes away second roll wheel assembly forward, and the second roller 7-5 and curvilinear guide 2 are thrown off, and takes off cutter sweep at last.
