[0002] The gantry five-axis linkage machining center is a commonly used high-precision and high-efficiency machine tool. It has three linear coordinates (X, Y, Z), one rotary coordinate axis (A-axis) that rotates on its own axis, and one rotary coordinate axis (B-axis) that revolves around the center. The cutting feed device is an important component of this machine tool, which generally includes the feed of the cutting head and the feed of the material.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the interplay of a motor, blades, cylinders, and threaded tubes to transport materials via a conveyor belt to the top of a load-bearing plate. The material gradually contacts the clamping plate, which, in conjunction with a slider and a second spring, clamps and limits the material's movement. When the height of the cross plate needs adjustment, the cylinder is activated, moving the cross plate up and down via a fixed block. To move the motor forward / backward or left / right, an electric roller is activated, moving the top of the cross plate and driving a disc. This disc, via a vertical rod, moves a movable block within the first cross groove. The movable block, via a fixed column, drives the motor. The position of the blade can then be adjusted. After the blade position is adjusted, the electric roller is stopped and the motor is started. The motor drives the transmission rod to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear drives two second bevel gears to rotate, which in turn drives the crossbar to rotate. The crossbar drives the tooth block to rotate, which in turn drives the gear to rotate. The gear drives the tooth ring to rotate, which in turn drives the rotating rod to rotate. The rotating rod drives the convex plate to rotate, which in turn drives the blade to rotate. The blade can then cut the material. The U-shaped plate, together with the first threaded rod and the first nut, can limit the position of the blade to prevent displacement during rotational cutting. If, during the machining process, only the left blade needs to rotate for cutting, while the right blade does not need to rotate, rotate the right second nut. The right second nut moves out of the surface of the right second threaded rod and moves the right second threaded rod to the left. The right second threaded rod drives the right fixed ring and the right gear, moving the right gear away from the right tooth block and the right tooth ring. This prevents the right tooth block from meshing with the right tooth ring, so that when the crossbar rotates, the right rotating rod will not be able to rotate, and consequently, the right blade will not be able to rotate for cutting. If the axial position of the blade needs to be adjusted, initially, the blade is located on the left and right sides of the device. The limiting rod passes through the first connecting ring and the transmission rod. Then, the motor is started. The motor drives the transmission rod to rotate. The transmission rod, in conjunction with the limiting rod, drives the first connecting ring to rotate. The first connecting ring drives the L-shaped rod to rotate. The L-shaped rod drives the second connecting ring to rotate. The second connecting ring drives the horizontal rod to rotate. The horizontal rod drives the rotating rod to rotate through the vertical plate. The rotating rod drives the blade to rotate, so that the blade rotates around the center of the transmission rod. After the blade has rotated a certain degree, the motor is turned off, and the limiting rod is removed from inside the transmission rod and the first connecting ring, thus completing the axial movement of the blade. When drilling is required, the operator takes out the drill bit, attaches the top of the drill bit to the bottom of the first bevel gear, attaches the connecting plate on the drill bit to the bottom of the first bevel gear, takes out the bolt, and connects the bolt threaded into the threaded hole on the connecting plate and the threaded hole at the bottom of the first bevel gear, thus installing the drill bit. The motor drives the transmission rod to rotate, the transmission rod drives the first bevel gear to rotate, and the first bevel gear drives the drill bit to rotate through the bolt and the connecting plate, so that the drill bit can drill holes in the material.

An L-shaped plate 8 is fixedly connected to the side of the fixing block 4 away from the cross plate 5. The side of the L-shaped plate 8 away from the fixing block 4 passes through the adjacent through groove and is fixedly connected... The load-bearing plate 1 is equipped with a fixed plate 9. Two sliding grooves are opened on the top of the load-bearing plate 1 near the left and right sides. Slider 47 is movably connected in the sliding groove. The top of two adjacent sliders 47 are fixedly connected to a clamping plate 46. A second spring 48 is fixedly connected to one side of each slider 47. The end of the second spring 48 away from the slider 47 is fixedly connected to the inner wall of the adjacent sliding groove. Conveyor belts 3 are installed on the front and rear sides of the load-bearing plate 1. Four first threaded holes are opened on the bottom of the first bevel gear 16 near the outer edge. A drill bit 19 is attached to the center of the bottom of the first bevel gear 16. Four connecting plates 44 are fixedly connected to the outer edge of the drill bit 19 near the top. A second threaded hole is opened on each connecting plate 44. A bolt 45 is threaded into each second threaded hole. The top of the bolt 45 is threaded into the first threaded hole.

[0018] Working principle: When the device starts working, the conveyor belt 3 is started, and the conveyor belt 3 transports the material to the top of the load-bearing plate 1. The material gradually contacts the clamping plate 46. The clamping plate 46, with its inclined front and rear sides, allows the material to gradually open the clamping plate 46. The clamping plate 46 drives the slider 47 to move, and the slider 47 drives the second spring 48 to compress. When the material moves to the center of the top of the load-bearing plate 1, the conveyor belt 3 is stopped. The clamping plate 46, together with the slider 47 and the second spring 48, clamps and limits the material. When it is necessary to adjust the height of the cross plate 5, the cylinder 6 is started. The cylinder 6 drives the cross plate 5 to move up and down through the fixing block 4. The fixing block 4 drives the L-shaped plate 8 and the fixing plate 9 to move. The L-shaped plate 8 moves in the through groove on the horizontal plate 7. When the cross plate 5 is moved to the appropriate position, the cylinder 6 is stopped. If it is necessary to move the motor 14 forward or backward or left or right, the electric roller 50 is started. The electric roller 50 will move on top of the cross plate 5, driving the disc 10 to move. The disc 10 drives the movable block 12 to move via the vertical rod 11. The movable block 12 moves within the first cross groove. The movable block 12 drives the motor 14 to move via the fixed column 13. The motor 14 can then adjust the position of the blade 24. After the position of the blade 24 is adjusted, the electric roller 50 is stopped and the motor 14 is started. The motor 14 drives the transmission rod 15 to rotate, which in turn drives the first bevel gear 16 to rotate. The first bevel gear 16 drives... Two second bevel gears 17 rotate, driving the crossbar 49 to rotate. The crossbar 49 drives the toothed block 25 to rotate, which in turn drives the gear 26 to rotate. The gear 26 drives the gear ring 27 to rotate, which in turn drives the rotating rod 21 to rotate. The rotating rod 21 drives the convex plate 22 to rotate, which in turn drives the blade 24 to rotate. The blade 24 can then cut the material. The U-shaped plate 34, in conjunction with the first threaded rod 35 and the first nut 36, can limit the position of the blade 24, preventing displacement during rotational cutting. The first threaded rod 35 passes through the limiting plate 32, rotating the first nut 36 to the surface of the first threaded rod 35, thereby limiting the U-shaped plate 34 and thus the blade 24. To limit the movement, if it is necessary to adjust the position of the blade 24 itself, first remove the first nut 36 from the surface of the first threaded rod 35, then move the threaded tube 33 on the crossbar 49 to the external thread 20. During the adjustment of the position of the blade 24 itself, the motor 14 is in the off state. Rotate the threaded tube 33, and the threaded tube 33 rotates and moves through the external thread 20. The threaded tube 33 drives the T-block 37 to move, moving the T-block 37 into the connecting groove at the top of the U-shaped plate 34. The T-block 37 will contact the inclined surface of the insertion rod 38 and drive the insertion rod 38 to move forward. The insertion rod 38, in conjunction with the limiting plate 40, drives the first spring 39 to stretch. The T-block 37 will continue to move until the rear end of the insertion rod 38 is inserted into the blind hole on the front side of the T-block 37.The first spring 39 returns to its initial state. At this point, the position of the threaded tube 33 can be adjusted manually by rotating it, or by the motor 14 driving the transmission rod 15, the first bevel gear 16, the second bevel gear 17, the crossbar 49, and the external thread 20. The threaded tube 33 will move the U-shaped plate 34 via the T-block 37 and the insert rod 38. The U-shaped plate 34 will move the blade 24 and the first threaded rod 35. When the blade 24 has moved to the desired position, the movement of the threaded tube 33 will stop. The insert rod 38 will be pulled forward to remove it from the blind hole on the front side of the T-block 37. The threaded tube 33 will then be moved again to remove the T-block 37 from the connecting groove at the top of the U-shaped plate 34. Removing the T-block 37 eliminates the connection between it and the U-shaped plate 34. If, during processing, only the left blade 24 needs to rotate for cutting, and the right blade 24 does not need to rotate, rotating the right second nut 42 removes it from the surface of the right second threaded rod 41 and moves it to the left. The right second threaded rod 41 then drives the right fixed ring 43 and the right gear 26, disengaging the right gear 26 from the right toothed block 25 and right toothed ring 27. This prevents the right toothed block 25 from meshing with the right toothed ring 27, thus preventing the right rotating rod 21 from rotating when the crossbar 49 rotates, and consequently, the right blade 24 cannot rotate for cutting. If it is necessary to adjust the shaft of the blade 24... When adjusting the position, initially, the blade 24 is located on the left and right sides of the device. The limiting rod 18 passes through the first connecting ring 29 and the transmission rod 15. Then, the motor 14 is started, driving the transmission rod 15 to rotate. The transmission rod 15, in conjunction with the limiting rod 18, drives the first connecting ring 29 to rotate. The first connecting ring 29 drives the L-shaped rod 30 to rotate, which in turn drives the second connecting ring 31 to rotate. The second connecting ring 31 then drives the horizontal rod 49 to rotate. The horizontal rod 49, through the vertical plate 23, drives the rotating rod 21 to rotate. The rotating rod 21 then drives the blade 24 to rotate, causing the blade 24 to rotate around the center of the transmission rod 15. After rotating the blade 24 90 degrees, the motor 14 is turned off, and the limiting rod is adjusted. The rod 18 is removed from inside the transmission rod 15 and the first connecting ring 29, thus completing the axial movement of the blade 24. If drilling is required, the operator removes the drill bit 19, attaches its top to the bottom of the first bevel gear 16, and attaches the connecting plate 44 on the drill bit 19 to the bottom of the first bevel gear 16. The bolt 45 is then removed and threaded into the threaded hole on the connecting plate 44 and the threaded hole at the bottom of the first bevel gear 16, thereby installing the drill bit 19. The motor 14 drives the transmission rod 15 to rotate, which in turn drives the first bevel gear 16 to rotate. The first bevel gear 16, through the bolt 45 and the connecting plate 44, drives the drill bit 19 to rotate, allowing the drill bit 19 to perform drilling operations on the material.
