Description

Technical Field

[0001] The present application relates to the technical field of milling equipment, and in particular to a profile milling equipment. Background Art

[0002] Profile milling equipment is a kind of mechanical equipment specially used for processing metal profiles. It is mainly used for milling, drilling and other processing on metal profiles. The working principle of profile milling equipment is usually to fix the metal profile on the processing fixture, and use high-speed rotating saw blades, milling cutters, drill bits, etc. to perform cutting, milling, drilling and other processing.

[0003] However, when milling profiles, existing milling equipment usually performs end milling on the clamped profile (end milling refers to milling the end face of the profile to obtain the required shape and size) to facilitate subsequent tool alignment processing. However, since the profile is generally made of metal material and the structural strength of the milling cutter is at a fixed value, the cutting depth of the milling cutter cannot be too deep each time during the milling of the profile, otherwise there is a risk of tool breakage. Therefore, it is necessary to repeat milling on the profile many times to obtain the shape and size required for milling processing. However, repeated milling will increase the time spent on profile milling, resulting in low efficiency of profile milling processing and shortcomings. Summary of the invention

[0004] In order to improve the time spent in end milling of a profile, which results in a decrease in the efficiency of the overall profile milling process, the present application provides a profile milling device.

Through the process of one-time processing and two-milling, the time to achieve the required shape and size of the profile is shortened, thereby improving the efficiency of profile milling.

[0007] Optionally, the sliding assembly includes a transverse slide rail, a vertical slide rail and a longitudinal slide rail with the same structure which are arranged on the processing table, the length direction of the transverse slide rail, the length direction of the vertical slide rail and the length direction of the longitudinal slide rail are all arranged perpendicular to each other, the longitudinal slide rail includes a sliding beam, a screw rod is rotatably arranged on the sliding beam, a driving motor electrically connected to a control system is arranged on the sliding beam, the screw rod is coaxially arranged on the output shaft of the driving motor, a sliding block is threadedly connected to the screw rod, the vertical slide rail is arranged on the sliding block on the transverse slide rail, the longitudinal slide rail is arranged on the sliding block on the vertical slide rail, and the movable platform is arranged on the sliding block on the longitudinal slide rail.

[0010] By adopting the above technical solution, the control system starts the milling motor, and the output shaft of the milling motor drives the driving shaft to rotate synchronously through the coupling.

At the same time, the cutter barrel shaft drives the telescopic column and the gear tube shaft to slide relative to each other, thereby changing the milling depth of the milling cutter on the secondary cutter barrel on the profile, thereby ensuring the one-time processing and forming effect of the profile.

During the rotation of the cooling rod, the cooling nozzle on the cooling rod always points to the milling cutter on the main tool barrel. At the same time, since the relative positions of the main tool barrel, the secondary tool barrel and the cooling nozzle do not change with the rotation of the shaft tube, the control system supplies coolant to the cooling nozzle through a hydraulic pump and a hose, which can cool down the milling cutter on the main tool barrel and the milling cutter on the secondary tool barrel at the same time, thereby reducing the heat generated by milling of the profile and the milling cutter, which is beneficial to improving the surface processing accuracy of the profile and increasing the service life of the milling cutter.

When the milling distance of the milling cutter on the secondary cutter barrel to the profile is insufficient, the control system starts the electric cylinder, the piston rod of the electric cylinder extends and pushes the clamping block, and the clamping block drives the cutter barrel shaft to move synchronously and approach the profile through the lifting disc.

When the shaft tube rotates, the shaft tube drives the cooling rod to rotate synchronously. During the rotation of the cooling rod, the cooling nozzle on the cooling rod always points to the milling cutter on the main cutter barrel. At the same time, since the relative positions of the main cutter barrel, the secondary cutter barrel and the cooling nozzle do not change with the rotation of the shaft tube, the control system supplies coolant to the cooling nozzle through a hydraulic pump and a hose, which can cool down the milling cutter on the main cutter barrel and the milling cutter on the secondary cutter barrel at the same time, reducing the heat generated by milling of the profile and the milling cutter, which is beneficial to improving the surface processing accuracy of the profile and increasing the service life of the milling cutter.

[0036] The technician places the profile 1 on the fixed plate 33, and then tightens the bolts on the clamping block 34 to fix the profile 1 on the fixed plate 33, and then changes the angle of the angle plate 32 to make the profile 1 on the fixed plate 33 in a state to be milled, and then the control system starts the drive motor 533 on the transverse slide rail 51, the vertical slide rail 52 and the longitudinal slide rail 53. The drive motor 533 drives the sliding block 534 to slide along the length direction of the sliding beam 531 through the screw rod 532, so that the mobile platform 4 can move freely in the three-dimensional processing space formed by the transverse slide rail 51, the vertical slide rail 52 and the longitudinal slide rail 53.

[0037] Reference Figure 1 A conversion disk 6 with a hollow interior is bolted to the mobile platform 4. The conversion disk 6 is welded and assembled from multiple steel plates. A main tool cylinder 7 and a secondary tool cylinder 8 with the same structure are arranged on the conversion disk 6. Both the main tool cylinder 7 and the secondary tool cylinder 8 are provided with mounting holes 9 for mounting the milling cutter 0. The main tool cylinder 7 is coaxially rotatable and penetrates the conversion disk 6. A milling part 12 for driving the main tool cylinder 7 to rotate is arranged on the mobile platform 4.

[0038] Reference Figure 2 , Figure 3 and Figure 4 The milling part 12 includes a milling motor 121 bolted to the mobile platform 4 and electrically connected to the control system. A drive shaft 122 is coaxially connected to the conversion disk 6. A coupling 123 is arranged between one end of the drive shaft 122 and the output shaft of the milling motor 121, and the other end is coaxially welded to the main tool barrel 7.

[0039] Reference Figure 3 , Figure 4 and Figure 5A feed plate 10 is coaxially rotatably arranged on the conversion disk 6, and the secondary knife cylinder 8 is rotatably arranged on the feed plate 10. A transmission member 13 for transmitting torque is arranged between the main knife cylinder 7 and the secondary knife cylinder 8, and the transmission member 13 includes a primary gear 131 welded on the drive shaft 122. A transmission shaft 132 is rotatably connected to the feed plate 10, and the secondary knife cylinder 8 is arranged on the transmission shaft 132. A secondary gear 133 is arranged on the transmission shaft 132. A transmission gear 134 is rotatably connected to the feed plate 10, and the transmission gear 134 is meshed with the primary gear 131, and the transmission gear 134 is meshed with the secondary gear 133.

[0040] The technician installs the milling cutter 0 on the main cutter barrel 7 and the secondary cutter barrel 8, adjusts the gap between the milling cutter 0 on the main cutter barrel 7 and the milling cutter 0 on the secondary cutter barrel 8, and then starts the milling motor 121 through the control system. The output shaft of the milling motor 121 drives the driving shaft 122 to rotate through the coupling 123, and the driving shaft 122 drives the milling cutter 0 on the main cutter barrel 7 to rotate. At the same time, the driving shaft 122 drives the transmission gear 134 to rotate through the primary gear 131.

[0041] The transmission gear 134 drives the transmission shaft 132 to rotate through the secondary gear 133, and the transmission shaft 132 drives the milling cutter 0 on the secondary cutter cylinder 8 to rotate, so that the milling cutter 0 on the main cutter cylinder 7 and the milling cutter 0 on the secondary cutter cylinder 8 rotate in the same direction. At this time, the direction of one end of the moving platform 4 is the same as the direction from the secondary cutter cylinder 8 to the main cutter cylinder 7, and then the profile 1 is processed once and the effect of two millings is achieved.

[0042] Reference Figure 3 , Figure 4 and Figure 5 An arc avoidance groove 11 is coaxially provided on the conversion disk 6 for the secondary knife cylinder 8 to rotate through, and the central angle of the arc avoidance groove 11 does not exceed 180°. A stopper ring 23 is coaxially connected to the bottom of the conversion disk 6 for rotation. The stopper ring 23 is used to block the arc avoidance groove 11. The secondary knife cylinder 8 rotates through the stopper ring 23. A feed member 14 for driving the feed plate 10 to rotate is arranged on the conversion disk 6.

[0043] Reference Figure 4 , Figure 5 and Figure 6 The feed member 14 includes a shaft tube 141 coaxially arranged inside the conversion disk 6, the feed plate 10 is welded to the shaft tube 141, an inner gear ring 142 is coaxially welded inside the shaft tube 141, a feed motor 143 electrically connected to the control system is bolted to the conversion disk 6, and a feed gear 144 meshing with the inner gear ring 142 is welded on the output shaft of the feed motor 143.

[0044] Reference Figure 3 , Figure 4 and Figure 6A cooling rod 18 is welded on the shaft tube 141, and a sliding arc groove 19 is opened between the inner and outer walls of the conversion disk 6 for the cooling rod 18 to rotate. A cooling nozzle 20 is bolted to the cooling rod 18. The main tool barrel 7 is located on the connecting line between the secondary tool barrel 8 and the cooling nozzle 20. The cooling nozzle 20 points to the milling cutter 0 on the main tool barrel 7. A hydraulic pump 21 electrically connected to the control system is arranged on the bottom of the collection box 24, and a hose 22 is connected between the cooling nozzle 20 and the hydraulic pump 21.

[0045] When it is necessary to change the cutting amount of the milling cutter 0 on the secondary cutter barrel 8 on the profile 1, the technician starts the feed motor 143 through the control system. The output shaft of the feed motor 143 drives the feed gear 144 to rotate. The feed gear 144 drives the shaft tube 141 to rotate around the axis of the conversion disk 6 through the internal gear ring 142, thereby changing the distance between the milling cutter 0 on the main cutter barrel 7 and the milling cutter 0 on the secondary cutter barrel 8 in the moving direction of the moving platform 4, thereby changing the cutting amount of the milling cutter 0 on the secondary cutter barrel 8 on the profile 1.

[0046] At the same time, the shaft tube 141 drives the cooling rod 18 to rotate synchronously, so that the cooling nozzle 20 on the cooling rod 18 is always aimed at the milling cutter 0 on the main cutting barrel 7. Since the main cutting barrel 7 is located on the connecting line between the secondary cutting barrel 8 and the cooling nozzle 20, the control system starts the hydraulic pump 21, and the hydraulic pump 21 sprays the coolant from the cooling nozzle 20 through the hose 22. The coolant sprayed by the cooling nozzle 20 cools the milling cutter 0 on the secondary cutting barrel 8 at the same time, and flushes the waste milled by the milling cutter 0 off the milling surface of the profile 1.

[0047] Reference Figure 4 , Figure 5 and Figure 6 An electric cylinder 15 electrically connected to the control system is bolted to the feed plate 10. The transmission shaft 132 includes a coaxially arranged gear tube shaft 1321 and a knife barrel shaft 1322. The gear tube shaft 1321 is rotatably connected to the feed plate 10. The secondary gear 133 is welded to the gear tube shaft 1321. The secondary knife barrel 8 is coaxially welded to the knife barrel shaft 1322.

[0048] Reference Figure 4 , Figure 5 and Figure 6 A telescopic column 1323 with a regular polygonal cross section is coaxially welded on the knife barrel shaft 1322. The telescopic column 1323 is coaxially slidably matched with the gear tube shaft 1321. A lifting disc 16 is coaxially welded on the knife barrel shaft 1322. A block 17 with a C-shaped cross section is welded on the piston rod of the electric cylinder 15. The C-shaped groove of the block 17 is stuck in the edge of the lifting disc 16.

[0049] When it is necessary to increase the milling depth of the milling cutter 0 on the secondary barrel 8 on the profile 1, the technician starts the electric cylinder 15 through the control system. The piston rod of the electric cylinder 15 drives the clamping block 17 to slide in the direction close to the profile 1, and the clamping block 17 drives the barrel shaft 1322 to slide synchronously through the lifting disc 16.

[0050] The cutter barrel shaft 1322 drives the telescopic column 1323 and the tooth tube shaft 1321 to slide relative to each other, thereby adjusting the milling depth of the milling cutter 0 on the secondary cutter barrel 8 on the profile 1, and at the same time facilitating the control of the cutting position of the milling cutter 0 on the secondary cutter barrel 8 on the end face of the profile 1, thereby shortening the time required for technicians to obtain profiles 1 of special shapes and sizes.

[0051] The implementation principle of a profile milling equipment in an embodiment of the present application is as follows: a technician places the profile 1 on a fixed plate 33, and then tightens the bolts on the clamping block 34 to fix the profile 1 on the fixed plate 33, and then changes the angle of the angle disk 32 to put the profile 1 on the fixed plate 33 in a state to be milled, and then the control system starts the drive motor 533 on the transverse slide rail 51, the vertical slide rail 52 and the longitudinal slide rail 53, and the drive motor 533 drives the sliding block 534 to slide along the length direction of the sliding beam 531 through the screw rod 532, so that the mobile platform 4 can move freely in the three-dimensional processing space formed by the transverse slide rail 51, the vertical slide rail 52 and the longitudinal slide rail 53.

[0052] The technician installs the milling cutter 0 on the main cutter barrel 7 and the secondary cutter barrel 8, adjusts the gap between the milling cutter 0 on the main cutter barrel 7 and the milling cutter 0 on the secondary cutter barrel 8, and then starts the milling motor 121 through the control system. The output shaft of the milling motor 121 drives the driving shaft 122 to rotate through the coupling 123, and the driving shaft 122 drives the milling cutter 0 on the main cutter barrel 7 to rotate. At the same time, the driving shaft 122 drives the transmission gear 134 to rotate through the primary gear 131.

[0053] The transmission gear 134 drives the transmission shaft 132 to rotate through the secondary gear 133, and the transmission shaft 132 drives the milling cutter 0 on the secondary cutter cylinder 8 to rotate, so that the milling cutter 0 on the main cutter cylinder 7 and the milling cutter 0 on the secondary cutter cylinder 8 rotate in the same direction. At this time, the direction of one end of the moving platform 4 is the same as the direction from the secondary cutter cylinder 8 to the main cutter cylinder 7, and then the profile 1 is processed once and the effect of two millings is achieved.

[0054] When it is necessary to change the cutting amount of the milling cutter 0 on the secondary cutter barrel 8 on the profile 1, the technician starts the feed motor 143 through the control system. The output shaft of the feed motor 143 drives the feed gear 144 to rotate. The feed gear 144 drives the shaft tube 141 to rotate around the axis of the conversion disk 6 through the internal gear ring 142, thereby changing the distance between the milling cutter 0 on the main cutter barrel 7 and the milling cutter 0 on the secondary cutter barrel 8 in the moving direction of the moving platform 4, thereby changing the cutting amount of the milling cutter 0 on the secondary cutter barrel 8 on the profile 1.

[0055] At the same time, the shaft tube 141 drives the cooling rod 18 to rotate synchronously, so that the cooling nozzle 20 on the cooling rod 18 is always aimed at the milling cutter 0 on the main cutting barrel 7. Since the main cutting barrel 7 is located on the connecting line between the secondary cutting barrel 8 and the cooling nozzle 20, the control system starts the hydraulic pump 21, and the hydraulic pump 21 sprays the coolant from the cooling nozzle 20 through the hose 22. The coolant sprayed by the cooling nozzle 20 cools the milling cutter 0 on the secondary cutting barrel 8 at the same time, and flushes the waste milled by the milling cutter 0 off the milling surface of the profile 1.

[0056] When it is necessary to increase the milling depth of the milling cutter 0 on the secondary barrel 8 on the profile 1, the technician starts the electric cylinder 15 through the control system. The piston rod of the electric cylinder 15 drives the clamping block 17 to slide in the direction close to the profile 1, and the clamping block 17 drives the barrel shaft 1322 to slide synchronously through the lifting disc 16.

[0057] The cutter barrel shaft 1322 drives the telescopic column 1323 and the tooth tube shaft 1321 to slide relative to each other, thereby adjusting the milling depth of the milling cutter 0 on the secondary cutter barrel 8 on the profile 1, and at the same time facilitating the control of the cutting position of the milling cutter 0 on the secondary cutter barrel 8 on the end face of the profile 1, thereby shortening the time required for technicians to obtain profiles 1 of special shapes and sizes.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
