[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] like Figure 3-Figure 5 As shown, a dense step milling face milling cutter proposed in one embodiment of the present application comprises: The tool body 1 includes a columnar block 101, and a connecting groove 102 is configured on the columnar block 101. The connecting groove 102 includes a vertical through hole and a transverse through groove. The transverse through groove is used for limiting connection, so that the columnar block 101 can rotate with the rotating mechanism, thereby forming a milling process; There are eight toothed cutter blocks 2 and they are arranged in an array along the circumference of the columnar block 101 at its bottom edge. The toothed cutter blocks 2 are arranged in a triangular shape and one side is configured as an inclined surface and the other side is configured as a plane. A mounting groove 201 is configured on the plane of the toothed cutter block 2. The tooth axial direction and diameter of the toothed cutter block 2 are geometrically increased or decreased. The tooth axial diameter is the distance between the toothed cutter block 2 and the axis of the columnar block 101. This decrease or increase can form a gap between the rotation trajectories of each toothed cutter block 2, so that a step groove can be milled on the workpiece during the rotation process. The cutter head piece 3 is inserted and installed in the installation groove 201, and a through hole 301 is constructed in the middle part of the cutter head piece 3. A connecting hole 202 that runs through its plane and inclined surface is constructed in the toothed cutter block 2, and a threaded sleeve 203 is inserted and inserted in the connecting hole 202. A blade screw 4 that is threadedly connected to the threaded sleeve 203 is installed in the through hole 301 of the cutter head piece 3, wherein one end of the blade screw 4 is constructed with a conical block, and the end of the conical block is constructed with a cross blade edge for tightening or loosening operations. The provision of the threaded sleeve 203 can reduce the contact loss between the blade screw 4 and the toothed cutter block 2, and one end of the threaded sleeve 203 is constructed with a rectangular block for limiting, and the other end is a column tube for connecting the blade screw 4. Such a setting can facilitate its disassembly and installation, and avoids the overall replacement of the cutter body 1 after slipping or damage. Only the blade screw 4 and the threaded sleeve 203 need to be replaced, thereby increasing convenience.

[0022] like Figure 1-Figure 6 As shown, a cutter head disassembly device for a dense step milling face milling cutter proposed in one embodiment of the present application includes: a milling machine body 5, a workbench 501 is provided on the milling machine body 5, a moving mechanism 502 is installed on the workbench 501, a connecting tool 503 for connecting to the connecting groove 102 of the cutter body 1 is installed on the moving mechanism 502, the milling machine body 5 is an outer frame, the workbench 501 is a base on which a workpiece fixture can be installed, and the moving mechanism 502 is an existing three-axis displacement mechanism, and position adjustment is achieved through the threaded cooperation of the screw rod, and also includes: A lifting member 6 is installed at one of the corners of the workbench 501; The docking member 7 includes a mounting shell 701 fixedly connected to the lifting member 6, an end plate 702 is connected to the upper end of the mounting shell 701, and a telescopic docking column 703 for plugging with the tool body 1 is provided on the end plate 702. When the lifting member 6 moves upward, the telescopic docking column 703 on the end plate 702 is pushed to plug and match with the tool body 1 that has returned to the zero position; There are eight screw removal parts 8 and they are distributed in a circular array on the end plate 702. The screw removal parts 8 include a mounting block 801 that obliquely penetrates the end plate 702. The mounting block 801 is arranged opposite to the plane end of the toothed cutter block 2. A shaft cylinder 802 is rotatably mounted on the upper end of the mounting block 801. A screwdriver head 803 for contacting the blade screw 4 is slidably inserted in the shaft cylinder 802. A driving part 9 for driving multiple shaft cylinders 802 to rotate synchronously is installed at the bottom of the end plate 702. It should be noted that the telescopic docking column 703 is octagonal in shape, and its eight end angles correspond to eight toothed cutter blocks 2 and eight screw removal parts 8. Through the docking operation of the telescopic docking column 703 and the tool body 1, the eight screw removal parts 8 and the eight mounting slots 201 can be arranged opposite to each other, so that the screwdriver head 803 in the subsequent shaft cylinder 802 can accurately dock with the blade screw 4. A push-pull mechanism 10 is disposed on the mounting block 801 and is used to drive the screwdriver head 803 toward or away from the blade screw 4; After the milling operation is completed, if the cutter head piece 3 is damaged, it can be moved to the zero position by the moving mechanism 502. At this time, the cutter body 1 is located directly above the mounting shell 701. At this time, the lifting member 6 can be used to drive the mounting shell 701 and the end plate 702 to rise as a whole, and the telescopic docking column 703 can be used for position docking to ensure that the screw removal member 8 can be arranged relative to the mounting slot 201. During this process, the push-pull mechanism 10 pulls the screwdriver head 803 toward the inside of the shaft cylinder 802 to retract to prevent movement interference. When the telescopic docking column 703 is fully retracted, the shaft cylinder 802 and the through hole 301 on the cutter head piece 3 are on the same axis. The screwdriver head 803 is pushed toward the blade screw 4 by the push-pull mechanism 10 until it conflicts with it, and then the driving member 9 is used to synchronously drive all the shaft cylinders 802 to rotate, so as to realize the disassembly operation of the blade screw 4. There is no need to manually disassemble them one by one, and they can be disassembled in batches at one time, which increases the convenience of the device and does not require manual operation, saving manpower.

[0023] like Figure 1-Figure 2 As shown, in some embodiments, the lifting member 6 includes an electric push rod 601 fixedly connected to the workbench 501, and two guide rods 602 erected on both sides of the electric push rod 601 are fixedly connected to the workbench 501. A support plate 603 connected to the output end of the electric push rod 601 is slidably sleeved on the guide rod 602, and the mounting shell 701 is connected to the end of the support plate 603. The two guide rods 602 can guide the up and down movement of the support plate 603 so that it always moves in a vertical state to ensure the accurate docking of the telescopic docking column 703 with the tool body 1, thereby increasing safety.

[0024] like Figure 5As shown, in some embodiments, the telescopic docking column 703 includes an octagonal column rod 7031 constructed in the middle of the end plate 702, an octagonal column sleeve 7032 is sleeved on the octagonal column rod 7031, a support spring 7033 is connected between the octagonal column rod 7031 and the octagonal column sleeve 7032, and a notch 103 for plugging with the octagonal column sleeve 7032 is constructed at the bottom of the knife body 1. It should be noted that in the initial state, the top of the octagonal column sleeve 7032 is higher than the top of the mounting block 801, so the octagonal column sleeve 7032 is firstly connected with the notch of the knife body 1. 103 is plugged in, during which the angle of the tool body 1 can be adjusted by rotating the connecting knife piece 503 to ensure the accurate docking operation. When the lifting piece 6 continues to rise, the octagonal column rod 7031 will be gradually inserted into the depth of the octagonal column sleeve 7032, thereby squeezing the support spring 7033 to produce compression. A resistance block is constructed in the middle of the octagonal column rod 7031. When the resistance block resists the top of the octagonal column sleeve 7032, the shaft cylinder 802 will be on the same axis as the through hole 301 of the cutter head piece 3, so as to facilitate the subsequent screw removal operation.

[0025] like Figure 7-Figure 8 As shown, in some embodiments, the push-pull mechanism 10 includes a push spring 1001 connected to the inner end of the shaft cylinder 802, and the other end of the push spring 1001 is connected to a push plate 1002, and the push plate 1002 is configured with a convex column 1003 that is plugged into the screwdriver head 803, and the screwdriver head 803 is configured with a slot for tightly plugging with the convex column 1003 so that it can move with the push plate 1002, and the mounting block 801 is connected to a pulling member 11 for driving the push plate 1002 to move toward the inner end of the shaft cylinder 802. It should be noted that the pulling member 11 is mainly It is used to drive the push plate 1002 to move a certain distance toward the push spring 1001. It only needs that the screwdriver head 803 does not protrude from the shaft tube 802. When the shaft tube 802 rotates, the push spring 1001 always applies a thrust to the screwdriver head 803 toward the blade screw 4, so that the two are always in conflict. When the blade screw 4 is threadedly engaged with the threaded sleeve 203 and is disengaged, it will gradually move toward the inside of the shaft tube 802, thereby squeezing the push spring 1001 for compression until the blade screw 4 is completely disengaged from the threaded sleeve 203 to complete the removal operation of the blade piece 3.

[0026] like Figure 7-Figure 8As shown, in some embodiments, a transverse groove 8011 is constructed in the mounting block 801, and the pulling member 11 includes an L-shaped transverse plate 1101 slidably arranged in the transverse groove 8011, one end of the L-shaped transverse plate 1101 slides through the mounting block 801 and the end is fixedly connected to a vertical plate 1102, and an electromagnet 1103 is fixedly connected to the upper end of the vertical plate 1102, and a sliding rod 1104 that slides through the end of the shaft tube 802 is fixedly connected to one side of the push plate 1002, and an iron block 1105 that is arranged opposite to the electromagnet 1103 is constructed at the end of the sliding rod 1104. It should be noted that in the initial state, the L-shaped transverse plate 1101 is at the deepest part of the transverse groove 8011, and at this time, the vertical plate 1102 is fixedly connected to the upper end of the vertical plate 1102. When the electromagnet 1103 on the plate 1102 is energized, it can attract the iron block 1105 and move it, thereby driving the slide rod 1104 and the push plate 1002 to move toward the inner end of the shaft tube 802, and then squeezing the push spring 1001 to produce compression. At this time, the screwdriver head 803 shrinks into the shaft tube 802, so as to avoid affecting the upward movement of the end plate 702, and ensure that the shaft tube 802 can be smoothly docked with the through hole 301 of the cutter head piece 3. When the electromagnet 1103 loses power, the push plate 1002 will be reset by the thrust of the push spring 1001, thereby pushing the screwdriver head 803 to contact with the blade screw 4, so as to facilitate the screw removal operation.

[0027] like Figure 7-Figure 8 As shown, in some embodiments, one end of the L-shaped cross plate 1101 located in the cross groove 8011 is connected to a cross bar 1106, the cross bar 1106 slides through the mounting block 801 and is provided with an extrusion spring 1107 that abuts between the cross groove 8011 and the L-shaped cross plate 1101, and the mounting block 801 is provided with a clamping member 12 for limiting the L-shaped cross plate 1101. It should be noted that when the screwdriver head 803 drives the blade screw 4 to loosen the screw, the blade screw 4 will gradually move toward the inside of the shaft tube 802, thereby squeezing the slide bar 1104 to move toward the electromagnet 1103 until it abuts against the electromagnet 1103, and drives the vertical plate 1102 to continue The L-shaped horizontal plate 1101 will move toward the outside of the horizontal groove 8011 until it forms a locking position with the clamping part 12 and stops moving. At this time, the extrusion spring 1107 is in a compressed state, and during this period, the electromagnet 1103 is always energized to adsorb the slide bar 1104, so that it will not reset and the blade screw 4 will not pop out of the shaft tube 802. When the blade screw 4 is completely out of the threaded sleeve 203, the cutter head piece 3 is still hung on the blade screw 4. When the lifting part 6 moves downward, it will synchronously drive the cutter head piece 3 to move downward, so that it will be out of the mounting groove 201 on the toothed cutter block 2, realizing the disassembly operation. No manual operation is required throughout the process, which increases the degree of automation and is convenient and labor-saving.

[0028] like Figure 8-Figure 9As shown, in some embodiments, a vertical slot 8012 connected to the bottom of the horizontal slot 8011 is constructed in the mounting block 801, and the clamping member 12 includes an n-type block 1201 slidably mounted in the vertical slot 8012 and with the top abutting against the bottom side of the L-shaped horizontal plate 1101, and an electromagnet 2 1202 is installed at the bottom of the vertical slot 8012, and a compression spring 1203 is connected between the electromagnet 2 1202 and the n-type block 1201. It should be noted that the n-type block 1201 is initially located below the L-shaped horizontal plate 1101. When the L-shaped horizontal plate 1101 is pushed to the other side of the n-type block 1201, the elastic force of the compression spring 1203 will push it upward, thereby limiting the reset movement of the L-shaped horizontal plate 1101, thereby ensuring that the blade screw 4 It can be stored inside the shaft cylinder 802, while carrying the cutter head piece 3 out of the mounting slot 201, and then the personnel only needs to replace the cutter head piece 3, and put the new cutter head piece 3 on the part of the blade screw 4 protruding from the shaft cylinder 802, and when the lifting member 6 rises, the new cutter head piece 3 can be inserted into the mounting slot 201, and then by energizing the electromagnet 2 1202, the n-type block 1201 can be adsorbed and moved downward, so as to open the restriction on the reset movement of the L-shaped cross plate 1101, and then the shaft cylinder 802 is driven to rotate by the driving member 9, and then the screwdriver head 803 is used to tighten the blade screw 4 to realize the installation operation of the cutter head piece 3. There is no need to install and fix them one by one manually, and batch automatic installation can be carried out, thereby increasing the flexibility and convenience of the device.

[0029] like Figure 8-Figure 9 As shown, in some embodiments, a hexagonal slot 8021 is configured in the shaft cylinder 802, and the screwdriver head 803 is slidably installed in the hexagonal slot 8021. An expansion piece 8022 for limiting the blade screw 4 is configured in the middle of the hexagonal slot 8021. The expansion piece 8022 is six in number and is inclined toward the inner end of the shaft cylinder 802. When the blade screw 4 enters the hexagonal slot 8021, it will resist the expansion piece 8022 and produce elastic deformation until the blade screw 4 passes over the expansion piece 8022. At this time, the expansion piece 8022 will resist the conical shape of the blade screw 4. When a new cutter head 3 is to be installed later, the electromagnet 1103 loses the adsorption to the slide bar 1104. At this time, the elastic force of the push spring 1001 will be greater than the resistance force of the expansion piece 8022 to the inclined surface of the conical block of the blade screw 4, so that the blade screw 4 can be pushed over the expansion piece 8022, thereby realizing the operation of gradually screwing the blade screw 4 into the threaded sleeve 203, and ensuring the smooth progress of the installation operation.

[0030] like Fig.10As shown, in some embodiments, the driving member 9 includes a transmission shaft 901 rotatably connected to the mounting block 801 and located below the end plate 702, one end of the transmission shaft 901 is connected to the shaft cylinder 802 through a synchronous wheel and a synchronous belt transmission, the other end of the transmission shaft 901 is fixedly connected to a transmission gear 902, a toothed wheel 903 meshing with the transmission gear 902 is rotatably mounted at the bottom of the end plate 702, a turntable 904 is rotatably mounted at the bottom of the end plate 702, and a flat thread 905 meshing with a plurality of toothed wheels 903 is constructed on the turntable 904, a driving motor 906 is fixedly connected to the mounting shell 701, and the output shaft of the driving motor 906 is connected to the turntable 904. It should be noted that since the mounting block 801 is tiltedly mounted on the end plate 702, in order to facilitate alignment with the mounting groove 201, the transmission gear 902 and the toothed wheel 903 are both arranged obliquely relative to the turntable 904, and a conical surface is constructed on the turntable 904, and the plane thread 905 is constructed on the conical surface, that is, the plane thread 905 and the tooth surface of the toothed wheel 903 are arranged vertically relative to each other, and the teeth of the toothed wheel 903 are rectangular pieces, and are movably inserted in the thread groove of the plane thread 905 in turn. When the turntable 904 rotates, the plane thread 905 and the teeth of the toothed wheel 903 will be threadedly engaged, thereby driving multiple toothed wheels 903 to rotate synchronously, and then driving multiple shaft cylinders 802 to rotate synchronously, realizing the batch disassembly operation of the blade screws 4, without the need for manual drive, increasing the degree of automation, and saving manpower.
