Therefore, the quality of the supporting steel plates used to manufacture the towers is crucial, and the processing technology of the supporting steel plates directly affects the safety and stability of the towers.

[0003] In the traditional processing of supporting steel plates, in order to facilitate steel plate welding and improve welding strength and welding uniformity, a groove needs to be processed at the edge of the steel plate, that is, the edge of the steel plate needs to be trimmed.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 8 As shown, a tower-supported steel plate processing bevel trimming machine tool of the present invention comprises a bed 1 and a trimming structure 2, wherein the bed 1 is used to carry the steel plate, and the processed end face of the steel plate faces the trimming structure 2, the trimming structure 2 is installed on the bed 1 and can move in the lateral direction, and the trimming structure 2 performs trimming processing on the end face of the steel plate when moving; The trimming structure 2 is composed of a guide ring 3 and a plurality of tool structures on the guide ring 3. The upper and lower surfaces of the guide ring 3 are provided with annular grooves, and the annular grooves are composed of arc grooves 4 and line grooves 5. The length direction of the line grooves 5 is parallel to the moving direction of the trimming structure 2. The tool structure includes an arch frame 6, which is sleeved on the guide ring 3. Two guide columns 7 are provided on the upper and lower sides of the inner wall of the arch frame 6. The two guide columns 7 are slidably installed in the corresponding annular grooves. A milling cutter group is provided on the outer wall of the arch frame 6. The tool structure performs rotational movement along the direction of the annular groove.

[0019] In detail, the steel plate is placed on the bed 1, the processed end surface of the steel plate faces the trimming structure 2, and the length direction of the processed end surface of the steel plate is parallel to the moving direction of the trimming structure 2, the trimming structure 2 can perform trimming processing on the end surface of the steel plate, the guide ring 3 on the trimming structure 2 is mainly used to support and guide the multiple sets of tool structures thereon, the wire groove 5 on the guide ring 3 faces the steel plate, and the length direction of the wire groove 5 is parallel to the length direction of the processed end surface of the steel plate, the bow frame 6 can support the milling cutter group on the bow frame 6 through the guide columns 7 thereon, because two guide columns 7 are arranged on the upper and lower sides of the inner wall of the bow frame 6, the movement of the two guide columns 7 in the annular groove can be used to guide the direction of the bow frame 6 and the milling cutter group thereon.

[0020] When in use, the steel plate is fixed on the bed 1, and the processed end face of the steel plate faces the trimming structure 2. The multiple groups of tool structures on the trimming structure 2 circulate and move along the annular groove trajectory on the guide ring 3, that is, the bow frame 6 drives the guide column 7 thereon to move in the annular groove, and the bow frame 6 synchronously drives the milling cutter group thereon to move. When the bow frame 6 moves to the arc groove 4 position, the bow frame 6 performs an arc motion. When the bow frame 6 moves to the line groove 5 position, the bow frame 6 performs a linear motion. At this time, the milling cutter group thereon performs a linear motion synchronously. The milling cutter group in this state performs milling and trimming processing on the end face of the steel plate. Since the milling cutter group performs a linear motion at this time, it can A smaller plane area is processed on the end face of the steel plate, and multiple groups of milling cutter groups circulate along the annular groove trajectory. Since the trimming structure 2 moves laterally, the guide ring 3 and the multiple groups of tool structures thereon move synchronously. The multiple groups of milling cutter groups move laterally while moving along the annular groove trajectory. At this time, each milling cutter group in contact with the end face of the steel plate can process a smaller plane on the end face of the steel plate. With the continuous circulation of the multiple groups of milling cutter groups, the multiple planes processed on the end face of the steel plate are staggered and overlapped with each other, thereby forming a complete plane on the end face of the steel plate, realizing the trimming working mode of the steel plate, and improving the flatness of the end face of the steel plate after trimming.

[0021] In actual use, the tool structure is generally arranged into two opposite groups.

[0022] By utilizing the linear motion of the milling cutter group during the circular motion, the milling cutter group can perform plane milling processing on the end face of the steel plate, and then utilize the lateral movement of multiple groups of milling cutter groups to continuously perform plane processing on the end face of the steel plate, so that the end face of the steel plate forms a complete plane, which significantly improves the flatness of the end face of the steel plate after trimming, avoids the phenomenon that the traditional processing method will cause the end face of the steel plate to appear curved instead of flat, and improves the quality of subsequent welding.

[0023] Furthermore, the trimming structure 2 further includes an outer frame 8 located outside the guide ring 3, a rotating column 9 is rotatably provided in the middle of the outer frame 8, a platform 10 is rolled on the inner wall of the guide ring 3, the platform 10 is located in the gap between the two ends of the bow frame 6, the rotating column 9 passes through the platform 10 and the guide ring 3, and the rotating column 9 is rotatably connected to the platform 10, a plurality of connecting plates 11 are provided on the platform 10, and the connecting plates 11 are fixedly connected to the outer frame 8; A plurality of sliding sleeves 12 are rolled on the rotating column 9 , and a slide plate 13 is slidably inserted in each sliding sleeve 12 , and the end of the slide plate 13 is rotatably connected to the side wall of the bow frame 6 .

[0024] In detail, the sleeve 12 can be hidden on the inner side of the rotating column 9, and the outer frame 8, the platform 10 and the connecting plate 11 can support and fix the guide ring 3. Since the bow frame 6 needs to move along the annular groove trajectory, the platform 10 needs to be located in the gap between the two ends of the bow frame 6, so as to avoid interference between the bow frame 6 and the platform 10 and ensure the normal operation of the structure. The sleeve 12 and the slide plate 13 are both located on the inner side of the guide ring 3. When the rotating column 9 rotates, it can move the guide ring 3 through the sleeve 12 and the slide plate 13, thereby providing power for the movement of multiple sets of tool structures. Due to the limitation of the movement trajectory of the tool structure, the slide plate 13 needs to be rotatably connected to the bow frame 6, and the slide plate 13 needs to be able to slide relative to the rotating column 9.

[0025] Furthermore, the milling cutter group is composed of a vertical cutter 14 located in the middle and two side cutters 15 located at the upper and lower sides of the vertical cutter 14 , and the side cutters 15 are inclined relative to the vertical cutter 14 .

[0026] In detail, the vertical knife 14 can process a vertical surface on the end surface of the steel plate, and the two side knives 15 can process two inclined surfaces on the upper and lower sides of the end surface of the steel plate, thereby realizing the trimming of the steel plate. By combining a vertical cutter 14 and two side cutters 15 into a milling cutter group, and tilting the side cutters 15, the vertical cutter 14 and the side cutters 15 can be directly used to process vertical surfaces and inclined surfaces on the end surface of the steel plate when the trimming structure 2 moves, thereby facilitating the one-time trimming of the steel plate and avoiding the traditional processing method of first milling out the vertical surface and then milling out the inclined surface, thereby greatly improving the processing efficiency.

[0027] It should be pointed out that the projection positions of the vertical knife 14 and the side knife 15 on the horizontal plane are staggered.

[0028] Furthermore, two sets of knife holder structures for connecting with two side knives 15 are provided on the bow frame 6; The tool holder structure includes a base 16 fixed on the bow frame 6, an adjustment plate 17 is arranged on the base 16 for transverse sliding, a buckle plate 18 is arranged on the adjustment plate 17, and the buckle plate 18 is connected to the base 16 by bolts; The adjusting plate 17 and the buckle plate 18 are both provided with teeth, and the adjusting plate 17 and the buckle plate 18 are connected by the tooth clamping.

[0029] In detail, the gusset plate 18 is connected to the base 16 by bolts, and when the bolts are tightened, the gusset plate 18 squeezes the adjustment plate 17. The teeth on the adjustment plate 17 and the gusset plate 18 can be used to lock the position of the adjustment plate 17, thereby locking the position of the side knife 15. When it is necessary to adjust the bevel processing depth of the end face of the steel plate, the bolts on the gusset plate 18 can be loosened and the adjustment plate 17 can be pushed to move laterally on the base 16, so as to adjust the position of the side knife 15 relative to the steel plate.

[0030] Furthermore, the tool holder structure also includes a support frame 19 fixed on the adjustment plate 17, a gear 20 is rotatably provided inside the support frame 19, an oblique clamping plate 21 is obliquely fixed on the outer wall of the gear 20, the side knife 15 is fixed on the oblique clamping plate 21, and an arc-shaped rack 22 is vertically slidably provided inside the support frame 19, the teeth on the arc-shaped rack 22 are meshed with the teeth on the gear 20, and the arc-shaped rack 22 and the support frame 19 are fastened to each other by bolts.

[0031] In detail, the arc-shaped rack 22 is fastened and squeezed on the gear 20 by bolts, thereby locking the position of the gear 20. At this time, the inclination angles of the inclined clamping plate 21 and the side knife 15 are fixed. When the angle of the inclined surface of the steel plate end surface needs to be adjusted, the bolts on the arc-shaped rack 22 can be loosened and the arc-shaped rack 22 can be separated from the gear 20. By rotating the gear 20, the inclined clamping plate 21 and the side knife 15 can be tilted, thereby adjusting the angle of the side knife 15.

[0032] Furthermore, two side panels 23 are arranged opposite to each other on the bed body 1, and the trimming structure 2 is located between the two side panels 23; A guide rail 24, a lead screw 25 and a worm 27 are connected between the two side plates 23. The outer frame 8 is slidably mounted on the guide rail 24. A screw sleeve 26 is threadedly mounted on the lead screw 25. The screw sleeve 26 is fixedly connected to the outer frame 8. A worm wheel 28 is meshed on the worm 27. The worm wheel 28 is rotatably mounted on the outer frame 8, and the worm wheel 28 is drivingly connected to the rotating column 9. The guide rail 24 , the lead screw 25 and the worm 27 are parallel to each other.

[0033] In detail, when the lead screw 25 is rotated, the lead screw 25 can push the screw sleeve 26 to move, and the screw sleeve 26 drives the outer frame 8 to move, so that the trimming structure 2 moves laterally, and the outer frame 8 slides on the guide rail 24. When the worm 27 is rotated, since the worm 27 is engaged with the worm wheel 28, the worm 27 can drive the rotating column 9 to rotate through the worm wheel 28, thereby providing power for the circular motion of multiple milling cutter groups.

[0034] Further, a large wheel 29, a small wheel 30 and a main motor 32 are arranged on the side wall of one of the side plates 23, the large wheel 29 is transmission-connected to the lead screw 25, the small wheel 30 is transmission-connected to the worm 27, the large wheel 29 and the small wheel 30 are transmission-connected via a transmission belt 31, and the main motor 32 provides power for the large wheel 29; Among them, buckle covers 33 are buckled on the outer sides of the large wheel 29 , the small wheel 30 , the transmission belt 31 and the main motor 32 , and the buckle covers 33 are fixed on the side plate 23 .

[0035] In detail, the main motor 32 can drive the large wheel 29, the small wheel 30 and the transmission belt 31 to rotate synchronously, thereby providing power for the screw 25 and the worm 27. The diameter of the large wheel 29 is larger than the diameter of the small wheel 30. Therefore, the trimming structure 2 can make multiple groups of milling cutter groups perform rapid circular motion while slowly moving horizontally, and the buckle cover 33 can isolate and protect its internal structure.

[0036] Furthermore, a top plate 34 is fixed between the two side plates 23 , a plurality of oil cylinders 35 are disposed on the top plate 34 , and a pressing plate 36 for pressing down and fixing the steel plate is disposed at the movable end of the oil cylinder 35 .

[0037] In detail, when the steel plate is placed on the bed 1 , the oil cylinder 35 can push the pressing plate 36 downward and squeeze and fix the steel plate, thereby preventing it from shifting during processing, and the top plate 34 can support the oil cylinder 35 .

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
