Description

Technical Field

[0001] This invention relates to the field of milling machine technology, specifically to a multi-face milling processing device for milling machines. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the rotation of the milling cutter is the primary motion, while the movement of the workpiece and the milling cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to perform milling operations on a workpiece. Besides milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also machine relatively complex profiles. They are more efficient than planers and are widely used in mechanical manufacturing and repair departments. Milling is a machining method that uses a milling cutter as a cutting tool to machine the surface of an object. Milling machines include horizontal milling machines, vertical milling machines, gantry milling machines, profile milling machines, universal milling machines, and lever milling machines. Milling refers to machining workpieces using a rotating multi-edged cutting tool; it is a highly efficient machining method. During operation, the cutting tool rotates (performing the main motion), and the workpiece moves (performing the feed motion). The workpiece can also be stationary, but in this case, the rotating cutting tool must still move (simultaneously completing the main motion and feed motion).

[0003] Existing milling machines typically cannot mill multiple sides of a workpiece simultaneously, and the devices are difficult to adapt to different workpiece sizes by adjusting the distance between the milling cutters. Therefore, they do not meet the current requirements. To address this, we propose a multi-face milling device for milling machines. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-face milling processing device for milling machines, in order to solve the problems mentioned in the background art, such as the inability to simultaneously mill multiple faces of a workpiece during milling, and the difficulty in adapting the device to the size of different workpieces to adjust the distance between the milling cutters.

[0008] Preferably, each of the inner rods of the movable bar is fixedly installed with a milling cutter holder, and each of the bottom ends of the milling cutter holder is provided with a clamping groove, and the top end of each milling cutter is movably inserted into the clamping groove.

[0009] Preferably, all the movable bars are movably engaged inside the cross groove, and all the lead screw motors are movably engaged inside the placement groove.

[0010] Preferably, each of the cross slots is provided with multiple fixed platform limiting slots, each fixed platform limiting slot is movably installed with a limiting block, each limiting block has an iron-nickel alloy rod fixedly installed on its inner surface, each fixed platform limiting slot has a spring groove, each spring groove has a compression spring movably installed inside, each iron-nickel alloy rod is movably inserted into the spring groove, and each milling cutter fixing platform is provided with an electromagnetic coil near the spring groove.

[0011] Preferably, the front side surface of the milling cutter fixing table is provided with a pressing rod, the inside of the milling cutter fixing table is provided with a power source, the power source is electrically connected to an electromagnetic coil, one end of the power source is provided with a stationary contact piece, the other end of the power source is provided with a moving contact piece, a return spring is movably installed on the surface of the moving contact piece, and the inner surface of the pressing rod is in contact with the surface of the moving contact piece.

[0012] Preferably, the outer surface of each movable strip is provided with four movable strip mounting slots, and each limiting block is movablely engaged into the interior of the movable strip mounting slot.

[0013] Preferably, the bottom end of each limiting block is provided with an arc groove.

[0014] Preferably, a part clamping platform is provided below the milling cutter fixing table, and a workpiece is movably mounted on the surface of the part clamping platform.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the cooperation of the movable bar and the milling cutter holder, allows the device to be used by controlling the rotation of the lead screw via the lead screw motor, thereby moving the movable block on the surface of the lead screw. This, in turn, drives the milling cutter motor to move laterally on the top surface of the milling cutter fixed table, which in turn drives the milling cutter holder to move at the bottom end of the movable bar. This adjusts the distance between the two milling cutters, thus facilitating the milling of workpieces of different sizes. By using the cross slot and the movable bar, when it is necessary to adjust the distance between the two milling cutters, first, both milling cutters are rotated by the lead screw motor to return them to the center position at the bottom of the movable bar. Then, the movable bar is pulled out of the cross slot. Then, by rotating the movable bar, the direction of the lead screw motor and the lead screw are simultaneously rotated by the connecting rod, making it rotate 90 degrees, so that the direction of the movable bar is aligned with the cross slot. The movable bar can then be inserted into the cross slot and fixed, so that the milling cutter is positioned at the bottom of the milling cutter fixing table. This adapts to different workpiece processing conditions. Furthermore, through the cooperation of the milling cutter and the milling cutter holder, the device allows for easy assembly and disassembly of the milling cutter. Thus, the device can perform milling processing on a workpiece with one milling cutter at the same time, or it can perform multi-face milling processing on a workpiece with two milling cutters. 2. The present invention, through the cooperation of the limiting block and the movable strip mounting groove, allows the surface of the limiting block with the arc groove to be impacted by the movable strip when the movable strip is placed inside the cross groove. This causes the limiting block to retract into the limiting groove of the fixed platform. Subsequently, the limiting block is ejected by the elastic potential energy of the compression spring and engages with the movable strip mounting groove, thereby fixing the movable strip inside the cross groove and preventing the movable strip from falling out and rotating due to gravity. By coordinating the pressing rod and the electromagnetic coil, when the device needs to adjust the position of the milling cutter holder and rotate the movable bar, the pressing rod can be pressed inward to collide with the moving contact piece. This causes the moving contact piece to bend inward and contact the stationary contact piece, thereby energizing the power supply and the electromagnetic coil. At this time, the electromagnetic coil generates magnetic force, which pulls the iron-nickel alloy rod into the spring groove, thereby causing the limit block to move out of the movable bar's mounting slot and releasing the movable bar's limitation. Then, the pressing rod is released, and the moving contact piece will be reset by the elasticity of the return spring. At this time, the electromagnetic coil will be de-energized, thereby releasing the attraction force on the iron-nickel alloy rod, making it easy for the movable bar to be reinstalled into the cross groove.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The milling cutter motor (model D180M) mentioned in this invention can be obtained from the market or through private customization. Please see Figures 1 to 7 An embodiment of the present invention provides a multi-face milling processing device for a milling machine, including a milling cutter fixing table 1, fixing blocks 2 fixedly installed on both sides of the milling cutter fixing table 1, two cross grooves 5 provided on the bottom surface of the milling cutter fixing table 1, and placement grooves 6 provided at both ends of the two cross grooves 5, a rotating shaft 11 movably installed inside the cross grooves 5, a movable strip 7 fixedly installed at the bottom end of the rotating shaft 11, a milling cutter clamping seat 9 movably installed at the bottom end of the movable strip 7, a milling cutter 10 movably installed at the bottom end of the milling cutter clamping seat 9, and multiple limiting blocks 26 movably installed inside the cross grooves 5.

[0020] By adopting the above technical solution, through the cooperation of the movable bar 7 and the milling cutter holder 9, the device can be used to control the rotation of the lead screw 14 by the lead screw motor 8, thereby moving the movable block 20 on the surface of the lead screw 14, which in turn drives the milling cutter motor 18 to move laterally on the top surface of the milling cutter fixed table 1, and then drives the milling cutter holder 9 to move at the bottom end of the movable bar 7, thereby adjusting the distance between the two milling cutters 10, thus facilitating the milling of workpieces of different sizes.

[0021] Furthermore, the bottom end of each rotating shaft 11 is movably connected to the inner rod 12 of the movable bar via a coupling, and the inner surface of each cross groove 5 is provided with a cross-shaped movable groove 13. Each rotating shaft 11 is movably inserted into the interior of the cross-shaped movable groove 13, and each inner rod 12 of the movable bar is movably inserted into the interior of the movable bar 7.

[0022] By adopting the above technical solution, through the cooperation of the rotating shaft 11 and the cross-shaped movable groove 13, the device can pull the movable bar 7 outward and rotate it, so that the movable bar 7 can rotate 90 degrees to adapt to different directions of the cross groove 5 for installation, thereby adjusting the position of the milling cutter 10.

[0023] Furthermore, the top of the milling cutter fixing table 1 is provided with two milling cutter motors 18. The bottom of each milling cutter motor 18 is movably connected to the rotating shaft 11 through a coupling. A movable block 20 is fixedly installed on one side of the top of each milling cutter motor 18. A lead screw 14 is movably installed on the surface of each movable block 20. A lead screw motor 8 is provided at one end of each lead screw 14. The outer surface of each lead screw motor 8 is fixedly connected to the movable bar 7 through a connecting rod.

[0024] Furthermore, each of the inner rods 12 of the movable bar is fixedly installed with a milling cutter holder 9, and each of the bottom ends of the milling cutter holder 9 is provided with a clamping groove 19, and the top end of the milling cutter 10 is movably inserted into the inside of the clamping groove 19.

[0025] By adopting the above technical solution, the device can freely assemble and disassemble the milling cutter 10 through the cooperation of the milling cutter 10 and the milling cutter holder 9. This allows the device to perform milling on the workpiece with one milling cutter 10, or to perform multi-face milling on the workpiece with two milling cutters 10.

[0026] Furthermore, the movable bars 7 are all movably engaged inside the cross grooves 5, and the lead screw motors 8 are all movably engaged inside the placement grooves 6.

[0027] By adopting the above technical solution, through the cooperation of the cross groove 5 and the movable bar 7, when it is necessary to adjust the distance between the two milling cutters 10, firstly, both milling cutters are rotated by the lead screw motor 8 to control the lead screw 14 to return to the center position at the bottom of the movable bar 7. Then, the movable bar 7 is pulled out from the cross groove 5. Then, by rotating the movable bar 7, the direction of the lead screw motor 8 and the lead screw 14 are simultaneously rotated by the connecting rod, so that the movable bar 7 is aligned with the direction of the cross groove 5. Thus, the movable bar 7 can be inserted into the interior of the cross groove 5 and fixed. This allows the milling cutter 10 to be positioned at the bottom of the milling cutter fixing table 1, thereby adapting to different workpiece processing conditions.

[0028] Furthermore, the interior of the cross groove 5 is provided with multiple fixed platform limiting grooves 25, and the interior of each fixed platform limiting groove 25 is movably installed with a limiting block 26. The inner surface of each limiting block 26 is fixedly installed with an iron-nickel alloy rod 28. The interior of each fixed platform limiting groove 25 is provided with a spring groove 29, and the interior of each spring groove 29 is movably installed with a compression spring 30. The iron-nickel alloy rod 28 is movably inserted into the interior of the spring groove 29. The milling cutter fixing table 1 is provided with an electromagnetic coil 31 near the spring groove 29.

[0029] By adopting the above technical solution, through the cooperation of the limiting block 26 and the movable bar mounting groove 15, when the movable bar 7 is placed inside the cross groove 5, the surface of the limiting block 26 with the arc groove 27 is impacted by the movable bar 7, thereby causing the limiting block 26 to retract into the fixed platform limiting groove 25. Subsequently, the limiting block 26 is ejected by the elastic potential energy of the compression spring 30 and jammed into the movable bar mounting groove 15, thereby fixing the movable bar 7 inside the cross groove 5 and preventing the movable bar 7 from falling out and rotating due to gravity.

[0030] Furthermore, a pressing rod 4 is provided on the front side surface of the milling cutter fixing table 1, and a power supply 21 is provided inside the milling cutter fixing table 1. The power supply 21 is electrically connected to the electromagnetic coil 31. One end of the power supply 21 is provided with a stationary contact piece 22, and the other end of the power supply 21 is provided with a moving contact piece 23. A return spring 24 is movably installed on the surface of the moving contact piece 23, and the inner surface of the pressing rod 4 is in contact with the surface of the moving contact piece 23.

[0031] By adopting the above technical solution, through the cooperation of the pressing rod 4 and the electromagnetic coil 31, when the device needs to adjust the position of the milling cutter holder 9 and needs to rotate the movable bar 7, the pressing rod 4 can be pressed inward, causing the pressing rod 4 to collide with the moving contact piece 23, causing the moving contact piece 23 to bend inward and contact the stationary contact piece 22, thereby energizing the power supply 21 and the electromagnetic coil 31. At this time, after the electromagnetic coil 31 is energized, it generates magnetic force and pulls the iron-nickel alloy rod 28 into the interior of the spring groove 29, thereby causing the limiting block 26 to move out of the interior of the movable bar mounting groove 15 and releasing the limiting of the movable bar 7. Then the pressing rod 4 is released, and the moving contact piece 23 will be reset by the elasticity of the return spring 24. At this time, the electromagnetic coil 31 will be de-energized, thereby releasing the attraction force on the iron-nickel alloy rod 28, making it convenient for the movable bar 7 to be reinstalled into the interior of the cross groove 5.

[0032] Furthermore, the outer surface of the movable strip 7 is provided with four movable strip mounting slots 15, and the limiting blocks 26 are all movablely inserted into the interior of the movable strip mounting slots 15.

[0033] Furthermore, each of the limiting blocks 26 has an arc groove 27 at its bottom end.

[0034] Furthermore, a part clamping table 3 is provided below the milling cutter fixing table 1, and a workpiece is movably mounted on the surface of the part clamping table 3.

[0035] Working principle: In use, through the cooperation of the movable bar 7 and the milling cutter holder 9, the device can be used to control the rotation of the lead screw 14 by the lead screw motor 8, thereby moving the movable block 20 on the surface of the lead screw 14. This causes the milling cutter motor 18 to move laterally on the top surface of the milling cutter fixed table 1, which in turn causes the milling cutter holder 9 to move at the bottom end of the movable bar 7, thereby adjusting the distance between the two milling cutters 10, thus facilitating the milling of workpieces of different sizes. By using the cross groove 5 and the movable bar 7, when it is necessary to adjust the distance between the two milling cutters 10, both milling cutters are first rotated by the lead screw motor 8 to control the lead screw 14 to return to the center position at the bottom of the movable bar 7. Then, the movable bar 7 is pulled out of the cross groove 5. Then, by rotating the movable bar 7, the direction of the lead screw motor 8 and the lead screw 14 are simultaneously rotated by the connecting rod to rotate it 90 degrees, so that the direction of the movable bar 7 is aligned with the cross groove 5. Thus, the movable bar 7 can be inserted into the interior of the cross groove 5 and fixed. This allows the milling cutter 10 to be positioned at the bottom of the milling cutter fixing table 1, thus adapting to different workpiece processing conditions. Furthermore, by using the cooperation between the milling cutter 10 and the milling cutter clamping seat 9, the device can be freely disassembled and assembled with the milling cutter 10. Thus, the device can perform milling processing on the workpiece with one milling cutter 10, or it can perform multi-face milling processing on the workpiece with two milling cutters 10. By cooperating with the limiting block 26 and the movable bar mounting groove 15, when the movable bar 7 is placed inside the cross groove 5, the surface of the limiting block 26 with the arc groove 27 is impacted by the movable bar 7, thereby causing the limiting block 26 to retract into the fixed platform limiting groove 25. Subsequently, the limiting block 26 is ejected by the elastic potential energy of the compression spring 30 and is locked into the movable bar mounting groove 15, thereby fixing the movable bar 7 inside the cross groove 5 and preventing the movable bar 7 from falling out and rotating due to gravity. With the cooperation of the pressing rod 4 and the electromagnetic coil 31, when the device needs to adjust the position of the milling cutter holder 9 and the movable bar 7 needs to be rotated, the pressing rod 4 can be pressed inward to make the pressing rod 4 collide with the moving contact piece 23, causing the moving contact piece 23 to bend inward and contact the stationary contact piece 22, thereby energizing the power supply 21 and the electromagnetic coil 31. At this time, the electromagnetic coil 31 generates magnetic force after being energized, which pulls the iron-nickel alloy rod 28 into the spring groove 29, thereby causing the limiting block 26 to move out of the movable bar mounting groove 15 and releasing the limiting of the movable bar 7. Then the pressing rod 4 is released, and the moving contact piece 23 will be reset by the elasticity of the return spring 24. At this time, the electromagnetic coil 31 will be de-energized, thereby releasing the attraction force on the iron-nickel alloy rod 28, making it convenient for the movable bar 7 to be reinstalled into the cross groove 5.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
