The bottom of the base plate is fixedly connected with a base, and the top of the bracket is fixedly connected with a moving component. The present invention sets a working mechanism. When the workpiece is sprayed and cooled, excess cutting fluid will remain on the surface of the workbench. When the workpiece is subsequently disassembled, not only the surface of the workpiece but also the workbench must be blown, thereby increasing the workload of the staff. Before processing the workpiece, the limit component is adjusted so that the limit component drives the connecting plate to move downward in the clearance groove, thereby allowing the resisting component to separate from the through hole.

Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled milling machines, and in particular to a numerically controlled milling machine and a cutter for composite conductive rail joint grooves. Background Art

[0002] CNC milling machine is a widely used machine tool. It can process planes (horizontal and vertical surfaces), grooves (keyways, T-slots, dovetail grooves, etc.), toothed parts (gears, spline shafts, sprockets), spiral surfaces (threads, spiral grooves) and various curved surfaces. In addition, it can also be used for machining the surface of rotating bodies, inner holes and cutting. When the CNC milling machine is working, the workpiece is mounted on the workbench or on accessories such as the indexing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or the milling head, and the workpiece can obtain the required machining surface. Due to multi-blade intermittent cutting, the productivity of the milling machine is relatively high.

[0003] When the milling machine is performing cutting processing, due to the high temperature of the cutting cutter, cutting fluid will be sprayed for cooling and lubrication. Due to the high cutting speed, the cutting fluid will splash around. After working for a long time, a large amount of cuttings will adhere to the surface of the cutting table and the milling machine, causing pollution to the mechanical working environment and affecting the service life of the milling machine. Summary of the invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: the composite conductive rail joint groove CNC milling machine and tool of the present invention include:

[0005] A bottom plate, wherein the bottom of the bottom plate is fixedly connected to a base, the top of the bottom plate is fixedly connected to a bracket, and the top of the bracket is fixedly connected to a moving component;

[0007] The connecting component comprises a connecting frame, a first motor is fixedly connected to a side of the connecting frame, a first screw rod is rotatably connected to an inner wall of the connecting frame, a connecting shaft is rotatably connected to two sides of the inner wall of the connecting frame away from the first screw rod, a connecting seat is slidably connected to a side of the connecting shaft, and a working mechanism is fixedly connected to the top of the connecting seat;

[0008] Preferably, the working mechanism includes a moving platform, the bottom of the moving platform is fixedly connected to the top of the connecting seat, the inner wall of the moving platform is provided with a clearance groove, a connecting plate is provided in the inner cavity of the clearance groove, the side of the connecting plate is in contact with the inner wall of the clearance groove, the top of the moving platform is evenly provided with through holes, the bottom of the moving platform is evenly provided with through holes, a connecting component is provided in the clearance groove, a connecting rod is fixedly connected to the side of the connecting plate, a resisting assembly is fixedly connected to the inner wall of the connecting plate, and both sides of the moving platform are fixedly connected to the limiting assemblies; when spraying and cooling the workpiece, Excess cutting fluid will remain on the surface of the workbench. When the workpiece is disassembled later, not only the surface of the workpiece needs to be blown, but also the workbench needs to be blown, which increases the workload of the staff. Before processing the workpiece, the limit component is adjusted so that the limit component drives the connecting plate and the connecting rice to move downward in the makeshift groove, so that the resisting component is separated from the through hole. When the workpiece is processed, the cutting fluid sprayed on the workpiece enters the inner cavity of the makeshift groove through the through hole, and the cutting fluid flowing into the makeshift groove flows out through the through hole, thereby avoiding the cutting fluid remaining on the workbench.

[0009] The top of the guide rod is fixedly connected with the top of the connecting plate, and the bottom of the guide rod is fixedly connected with the inner wall of the stop block. The top of the connecting plate is fixedly connected with the stop block, and the side of the stop block is slidably connected with the inner wall of the connecting plate. The top of the guide rod is fixedly connected with the stop plate. The first spring is sleeved on the guide rod, and the top of the first spring is fixedly connected with the top of the connecting plate, and the bottom of the first spring is fixedly connected with the inner wall of the stop groove. The bottom of the stop plate is fixedly connected with a telescopic rod, and the bottom of the telescopic rod is fixedly connected with the inner wall of the stop block. The bottom of the stop plate is fixedly connected with a second spring, and the telescopic rod and the second spring are cross-arranged, and the bottom of the second spring is fixedly connected with the inner wall of the stop block. When the connecting plate is driven to slide downward in the inner cavity of the stop groove by the limit block, the connecting plate drives the stop block to move downward, so that the stop block The release plate is provided to prevent the cutting fluid from entering the through-hole when the cutting fluid enters the give way groove, thereby clogging the through-hole and preventing the cutting fluid from flowing into the give way groove. At the same time, when the machine is turned off, after the limit plate is used to release the limit on the connecting plate, the stop block is reset by the stretching action of the second spring, so that the stop block blocks the through-hole, thereby preventing external dust and impurities from entering the give way groove through the through-hole when the machine is idle.

[0010] The top of the limit plate is provided with a groove, and the groove is arranged on the top of the limit plate, and the groove is arranged on the top of the limit plate, and the groove is cross-arranged with the groove, and the top of the limit plate is fixedly connected with the connecting block, and the top of the connecting block is rotatably connected with the rotating rod, and the top of the rotating rod is fixedly connected with the limiting block; before processing the workpiece, the limit plate is pressed downward so that the limit plate drives the connecting plate to slide in the inner cavity of the positioning groove. When the limit block passes through the groove and the bottom of the limit plate abuts against the top of the connecting block, the limit block is rotated so that the side of the limit block abuts against the inner wall of the mounting groove, thereby fixing the position of the connecting plate, preventing the connecting block from moving when the workbench is moving, thereby interfering with subsequent work.

[0011] Preferably, the movable component includes a mounting frame, a side surface of the mounting frame is fixedly connected to an end of the bracket away from the base plate, the top of the mounting frame is fixedly connected to a second motor, the inner wall of the mounting frame is rotatably connected to a second screw rod, the top of the second screw rod is fixedly connected to an output end of the second motor, the inner wall of the mounting frame is fixedly connected to guide shafts on both sides away from the second screw rod, the outer surface of the second screw rod is sleeved with a mounting seat, the side of the mounting seat is fixedly connected to a mounting plate, the top of the mounting plate is fixedly connected to a third motor, the inner wall of the mounting plate is sleeved with a knife handle, and the side of the mounting plate is fixedly connected to a spray pipe.

[0012] The composite conductive rail embedded groove tool comprises: the milling cutter component comprises a milling cutter, the inner wall of the milling cutter is provided with a connecting groove, the side of the milling cutter is fixedly connected with a chip discharge pipe, the two sides of the bottom of the milling cutter are provided with square grooves, the inner wall of the connecting groove is rotatably connected with a rotating shaft, and the side of the rotating shaft is fixedly connected with a spiral blade; when the third motor drives the milling cutter to mill the workpiece, when the groove is deep, the debris generated when the workpiece is processed will remain in the groove. If the debris is not cleaned, the debris remaining in the groove will squeeze the blade when the milling cutter is processing, thereby damaging the blade of the milling cutter. When the milling cutter processes the inner wall of the groove, if there are many debris in the groove, they will enter the connecting groove through the square groove. Since the spiral blade is fixedly connected to the inner wall of the connecting groove, the threaded blade will rotate synchronously when the milling cutter rotates, so that the debris entering the connecting groove through the square groove is driven by the rotation of the spiral blade to be discharged through the chip discharge pipe, thereby avoiding the debris in the groove from squeezing and damaging the blade of the milling cutter.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention sets a working mechanism. When the workpiece is sprayed to cool down, excess cutting fluid will remain on the surface of the workbench. When the workpiece is subsequently disassembled, not only the surface of the workpiece but also the workbench needs to be blown, thereby increasing the workload of the staff. Before processing the workpiece, the limit component is adjusted so that the limit component drives the connecting plate to move downward in the give way groove, thereby allowing the resisting component to separate from the through hole. When the workpiece is processed, the cutting fluid sprayed on the workpiece enters the inner cavity of the give way groove through the through hole, and the cutting fluid flowing into the give way groove flows out through the through hole, thereby preventing the cutting fluid from remaining on the workbench.

[0015] 2. The present invention provides a resisting assembly and a clearance plate to prevent the cutting fluid from entering the clearance groove and causing larger debris mixed in the cutting fluid to enter the through hole together, thereby blocking the through hole and preventing the cutting fluid from flowing into the clearance groove. At the same time, when the machine is turned off, after the limit plate releases the limit on the connecting plate, the resisting block is reset by the stretching action of the second spring, so that the resisting block resists the through hole, thereby preventing external dust and impurities from entering the clearance groove through the through hole when the machine is idle.

[0016] 3. The present invention sets a limit assembly. Before processing the workpiece, the limit plate is pressed downward so that the limit plate drives the connecting plate to slide in the inner cavity of the makeshift groove. When the limit block passes through the groove and the bottom of the limit plate abuts against the top of the connecting block, the limit block is rotated so that the side of the limit block abuts against the inner wall of the installation groove, thereby fixing the position of the connecting plate and preventing the connecting block from moving when the workbench is moving, thereby preventing interference with subsequent work.

[0017] 4. The present invention sets a milling cutter component. When the milling cutter mills a groove on a workpiece, when the groove is deep, debris generated when processing the workpiece will remain in the groove. If the debris is not cleaned, the debris remaining in the groove will squeeze the blade when the milling cutter is processing, thereby damaging the blade of the milling cutter. When the milling cutter processes the inner wall of the groove, if there are many chips in the groove, they will enter the connecting groove through the square groove. Since the spiral blade is fixedly connected to the inner wall of the connecting groove, the threaded blade will rotate synchronously when the milling cutter rotates, so that the debris entering the connecting groove through the square groove will be discharged through the chip discharge pipe driven by the rotation of the spiral blade, thereby preventing the debris in the groove from squeezing and damaging the blade of the milling cutter.

[0033] The working mechanism 36 includes a moving platform 361, the bottom of the moving platform 361 is fixedly connected to the top of the connecting seat 35, the inner wall of the moving platform 361 is provided with a clearance groove 362, the inner cavity of the clearance groove 362 is provided with a connecting plate 365, the side of the connecting plate 365 contacts the inner wall of the clearance groove 362, the top of the moving platform 361 is evenly provided with through holes 363, the bottom of the moving platform 361 is evenly provided with through holes 364, the clearance groove 362 is provided with a connecting component 3, the side of the connecting plate 365 is fixedly connected with a connecting rod 366, the inner wall of the connecting plate 365 is fixedly connected with a resisting component 367, and both sides of the moving platform 361 are fixedly connected with a limiting component 368; when spraying the workpiece When cooling by spraying, excess cutting fluid will remain on the surface of the workbench. When the workpiece is subsequently disassembled, not only the surface of the workpiece needs to be blown, but also the workbench needs to be blown, which increases the workload of the staff. Before processing the workpiece, by adjusting the limit component 368, the limit component 368 drives the connecting plate 365 to move downward in the makeshift groove 362, so that the resisting component 367 is separated from the through hole 364. When the workpiece is processed, the cutting fluid sprayed on the workpiece enters the inner cavity of the makeshift groove 362 through the through hole 364, and the cutting fluid flowing into the makeshift groove 362 flows out through the through hole 363, thereby avoiding the cutting fluid remaining on the workbench.

[0034] The retaining assembly 367 includes a guide rod 3671, the side of the guide rod 3671 is slidably connected to the inner wall of the connecting plate 365, the bottom of the guide rod 3671 is fixedly connected to the inner wall of the yielding groove 362, the top of the connecting plate 365 is fixedly connected with a retaining block 3672, the side of the retaining block 3672 is slidably connected to the inner wall of the connecting plate 365, the top of the guide rod 3671 is fixedly connected with a yielding plate 3673, the guide rod 3671 is sleeved with a first spring 3674, the top of the first spring 3674 is fixedly connected to the top of the connecting plate 365, and the bottom of the first spring 3674 is fixedly connected to the yielding groove The inner wall of the stop block 3672 is fixedly connected, the bottom of the give way plate 3673 is fixedly connected with a telescopic rod 3675, the bottom of the telescopic rod 3675 is fixedly connected to the inner wall of the stop block 3672, the bottom of the give way plate 3673 is fixedly connected with a second spring 3676, the telescopic rod 3675 and the second spring 3676 are cross-arranged, and the bottom of the second spring 3676 is fixedly connected to the inner wall of the stop block 3672; when the connecting plate 365 is driven to slide downward in the inner cavity of the give way groove 362 by the limit block 3687, the connecting plate 365 drives the stop block 3672 to move downward, so that the stop block 3672 672 is separated from the through hole 364, so that the cutting fluid sprayed onto the workbench during the processing of the workpiece can enter the inner cavity of the clearance groove 362 through the through hole 364. Since the bottom of the clearance plate 3673 is fixedly connected to the top of the guide rod 3671, the stop block 3672 will not move when it moves downward. When the stop block 3672 moves downward, the cutting fluid on the workbench flows into the through hole 364 through the gap formed by the stretching of the second spring 3676 and the telescopic rod 3675 and the clearance plate 3673. At the same time, by setting the clearance plate 3673 673 is used to prevent the cutting fluid from entering the clearance groove 362 and the larger debris mixed in the cutting fluid from entering the through hole 364, thereby blocking the through hole 364 and preventing the cutting fluid from flowing into the clearance groove 362. At the same time, when the machine is turned off, after the limit plate 3681 releases the limit on the connecting plate 365, the stop block 3672 is reset by the stretching action of the second spring 3676, so that the stop block 3672 blocks the through hole 364, thereby preventing external dust and impurities from entering the clearance groove 362 through the through hole 364 when the machine is idle.

[0035] The limiting assembly 368 includes a limiting plate 3681, one end of which is fixedly connected to the side of the connecting plate 365, a sliding rod 3682 is inserted into the limiting plate 3681, and both ends of the sliding rod 3682 are fixedly connected to the inner wall of the moving platform 361, a notch 3683 is provided on the top of the limiting plate 3681, and the inner wall of the notch 3683 is adapted to the side of the limiting block 3687, and a mounting groove 3684 is provided on the top of the limiting plate 3681, and the mounting groove 3684 and the notch 3683 are cross-arranged, the side of the moving platform 361 is fixedly connected to the connecting block 3685, and the top of the connecting block 3685 is rotatably connected to the rotating rod 3686, which is rotatably connected to the rotating plate 3686. The top of the rotating rod 3686 is fixedly connected to the limit block 3687; before processing the workpiece, the limit plate 3681 is pressed downward so that the limit plate 3681 drives the connecting plate 365 to slide in the inner cavity of the make way groove 362. When the limit block 3687 passes through the groove 3683 and the bottom of the limit plate 3681 abuts against the top of the connecting block 3685, the limit block 3687 is rotated so that the side of the limit block 3687 abuts against the inner wall of the mounting groove 3684, thereby fixing the position of the connecting plate 365 to prevent the connecting block 3685 from moving when the workbench is moving, thereby preventing interference with subsequent work.

[0037] Embodiment 2, use Figure 1-Figure 8 The composite conductor rail groove cutter of the present invention is described as follows:

[0038] like Figure 1-Figure 8 The composite conductive rail groove cutter of the present invention is based on the first embodiment;

[0039] The composite conductive rail inlay groove tool comprises: a milling cutter component 6 comprises a milling cutter 61, an inner wall of the milling cutter 61 is provided with a connecting groove 62, a side of the milling cutter 61 is fixedly connected with a chip discharge pipe 63, and both sides of the bottom of the milling cutter 61 are provided with square grooves 64, an inner wall of the connecting groove 62 is rotatably connected with a rotating shaft 65, and a side of the rotating shaft 65 is fixedly connected with a spiral blade 66; when the third motor 58 drives the milling cutter 61 to mill a groove on a workpiece, when the groove is deep, the debris generated when processing the workpiece will remain in the groove, and when the debris is not cleaned, the milling cutter 61 is processed. When the milling cutter 61 is rotating, the debris remaining in the groove will squeeze the blade and cause damage to the blade of the milling cutter 61. When the milling cutter 61 processes the inner wall of the groove, if there are a lot of debris in the groove, it will enter the connecting groove 62 through the square groove 64. Since the spiral blade 66 is fixedly connected to the inner wall of the connecting groove 62, the threaded blade will rotate synchronously when the milling cutter 61 rotates, so that the debris entering the connecting groove 62 through the square groove 64 is driven by the rotation of the spiral blade 66 and discharged through the chip discharge pipe 63, thereby preventing the debris in the groove from squeezing and damaging the blade of the milling cutter 61.

[0040] The specific workflow is as follows:

[0041] During operation, when processing the composite conductive rail embedding groove on the aluminum alloy, the aluminum alloy is fixed on the connecting component 3 through the pressing plate, and the moving component 5 drives the milling cutter component 6 to process the aluminum alloy conductive rail 201720972268.0 embedding groove of the stainless steel;

[0042] By turning on the first motor 32, the output end of the first motor 32 drives the first screw rod 33 to rotate in the inner wall of the connecting frame 31, and at the same time, the connecting seat 35 drives the working mechanism 36 to move;

[0043] At the same time, the second motor 52 is turned on, and the second screw rod 53 is driven to rotate through the output end of the second motor 52, so that the mounting seat 59 drives the milling cutter component 6 to perform groove milling processing on the workpiece on the workbench, and the cutting fluid is sprayed through the spray pipe 56, so as to cool the milling cutter component 6 and the workpiece being processed;

[0044] When the workpiece is sprayed to cool down, excess cutting fluid will remain on the surface of the workbench. When the workpiece is subsequently disassembled, not only the surface of the workpiece but also the workbench must be blown, which increases the workload of the staff. Before processing the workpiece, by adjusting the limit component 368, the limit component 368 drives the connecting plate 365 to move downward in the clearance groove 362, so that the resisting component 367 is separated from the through hole 364. When the workpiece is processed, the cutting fluid sprayed on the workpiece enters the inner cavity of the clearance groove 362 through the through hole 364, and the cutting fluid flowing into the clearance groove 362 flows out through the through hole 363, thereby preventing the cutting fluid from remaining on the workbench;

[0045] Before processing the workpiece, the limit plate 3681 is pressed downward so that the limit plate 3681 drives the connecting plate 365 to slide in the inner cavity of the yielding groove 362. When the limit block 3687 passes through the notch 3683 and the bottom of the limit plate 3681 abuts against the top of the connecting block 3685, the limit block 3687 is rotated so that the side of the limit block 3687 abuts against the inner wall of the installation groove 3684, thereby fixing the position of the connecting plate 365 to prevent the connecting block 3685 from moving when the workbench is moving, thereby preventing the subsequent work from being disturbed.

[0046] When the connection plate 365 is driven by the limit block 3687 to slide downward in the inner cavity of the yield groove 362, the connection plate 365 drives the stop block 3672 to move downward, so that the stop block 3672 is separated from the through hole 364, so that the cutting fluid sprayed onto the workbench during the processing of the workpiece can enter the inner cavity of the yield groove 362 through the through hole 364. Since the bottom of the yield plate 3673 is fixedly connected to the top of the guide rod 3671, the stop block 3672 will not move when it moves downward. When the stop block 3672 moves downward, the second spring 3676 and the telescopic rod 3675 are stretched to produce a stop block 3673. The notch allows the cutting fluid on the workbench to flow into the through hole 364. At the same time, the setting of the clearance plate 3673 prevents the cutting fluid from entering the clearance groove 362, and prevents the larger debris mixed in the cutting fluid from entering the through hole 364, thereby blocking the through hole 364 and preventing the cutting fluid from flowing into the clearance groove 362. At the same time, when the machine is turned off, after the limit plate 3681 releases the limit on the connecting plate 365, the stop block 3672 is reset by the stretching action of the second spring 3676, so that the stop block 3672 blocks the through hole 364, thereby preventing the dust and impurities from entering the clearance groove 362 through the through hole 364 when the machine is idle.

[0047] When the third motor 58 drives the milling cutter 61 to mill a groove on the workpiece, when the groove is deep, the debris generated when processing the workpiece will remain in the groove. If the debris is not cleaned, the debris remaining in the groove will squeeze the blade when the milling cutter 61 is processing, thereby damaging the blade of the milling cutter 61. When the milling cutter 61 processes the inner wall of the groove, if there are many chips in the groove, they will enter the connecting groove 62 through the square groove 64. Since the spiral blade 66 is fixedly connected to the inner wall of the connecting groove 62, the threaded blade will rotate synchronously when the milling cutter 61 rotates, so that the chips that enter the connecting groove 62 through the square groove 64 are driven by the rotation of the spiral blade 66 to be discharged through the chip discharge pipe 63, thereby avoiding the chips in the groove from squeezing and damaging the blade of the milling cutter 61.

[0048] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
