Description

Technical Field

[0001] The present invention relates to the technical field of processing auxiliary equipment, and particularly relates to an automated auxiliary processing mechanism for a machining center. Background Art

[0002] In the international processing field, high-speed machining is playing an increasingly important role. Compared with low-speed cutting, high-speed machining can not only double the production efficiency, but also further improve the machining accuracy and surface quality of parts. Since the 1990s, many high-speed machining centers and other high-speed, high-power, and precision CNC machine tools have been successively put on the international market, which indicates that high-speed machining technology has begun to enter the industrial application stage and has achieved relatively remarkable technical and economic benefits.

[0003] Traditional milling machine processing places the workpiece inside the milling machine for processing. After processing, the workpiece is first taken out and then placed again, resulting in low work efficiency.

[0004] The patent with the patent number CN201921879349.1 was publicly disclosed on June 19, 2020, and it discloses a rapid processing device for a milling machine, including a mounting frame, a rotating chain, and a clamping plate. A processing table is welded on the top of the mounting frame. One side of the mounting frame is bolted with a mounting plate. One side of the mounting plate is welded with a support plate through a welding rod. Tooth discs are respectively installed at both ends between the mounting plate and the support plate through bearings. The tooth discs are sleeved and connected by a rotating chain. Right-angle support plates are distributed and installed on the chain links on one side of the rotating chain. One end of the top of the right-angle support plate is welded with a spring rod. One side of the top of the spring rod is welded with a placement plate. Clamping plates are respectively arranged on both sides of the top of the placement plate. Slide grooves corresponding to the clamping plates are respectively opened on both sides of the top of the placement plate. Screws are respectively installed in the slide grooves through bearings. It greatly improves the efficiency of loading and processing, enables personnel to pre-load materials before processing the previous workpiece, shortens the time wasted in material replacement, and improves the processing efficiency.

[0005] Although the above patent improves the efficiency of replacing workpieces and enables continuous processing of plate parts, because its placement plate is set on the chain, its stability is poor, and the placement plate is prone to tilt during processing, which is likely to cause tool collision and deviation in the processing position, and its processing accuracy is low. Therefore, it is necessary to design an automated auxiliary processing mechanism for a machining center that can improve the efficiency of replacing workpieces while maintaining processing accuracy.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0032] Embodiment:

[0033] Refer to Figures 1 - 7, An automated auxiliary processing mechanism for a machining center, including a chassis 1, and further including: a mounting shaft 2 rotatably connected inside the chassis 1; a mounting plate 3 fixedly connected to the mounting shaft 2; a telescopic rod 5 fixedly connected to the mounting plate 3; a mounting disk 4 fixedly connected to the top of the mounting shaft 2; wherein, the output end of the telescopic rod 5 extends to the top of the mounting disk 4 to set a material fixing component; there are multiple groups of material fixing components, and multiple groups of material fixing components are circumferentially distributed on the mounting disk 4; wherein, at least one group of material fixing components is located outside the chassis 1.

[0034] Refer to Figure 4 , Preferably, there are four groups of material fixing components, and the four groups of material fixing components are evenly circumferentially distributed.

[0035] Refer to Figure 1 , At least one group of the four groups of material fixing components is arranged outside the chassis 1, which is convenient for the staff to replace the new material plate.

[0036] Refer to Figure 3 , When the material fixing component moves under the milling cutter, it will rise so that it is higher than the hole opened on the chassis 1 for the material fixing component to pass through, avoiding the splashes inside the chassis 1 from reaching the staff through the side wall of the chassis 1, and at the same time avoiding the milling cutter being ejected and hurting the staff when the cutter is broken.

[0037] Refer to Figure 5 , The material fixing component includes a mounting table 6 fixedly connected to the top of the telescopic rod 5. A cross slot 7 is opened on the mounting table 6. Four clamping jaws 8 are slidably connected to the cross slot 7. A spiral gear disk 9 is rotatably connected inside the mounting table 6. The spiral teeth of the spiral gear disk 9 are meshed with the bottom of the clamping jaws 8.

[0038] Refer to Figure 5 , Four clamping jaws 8 are provided, and the adjacent two clamping jaws 8 form a 90-degree angle, which is convenient for clamping and fixing rectangular, square and circular plates. And by driving the spiral gear disk 9 to rotate, the distance between the four groups of clamping jaws 8 from the center of the mounting table 6 is adjusted, so as to facilitate clamping and fixing plates of different sizes.

[0039] Refer to Figure 5 , A first motor 11 is fixedly connected to the side wall of the mounting table 6. The output shaft of the first motor 11 extends into the mounting table 6 and rotates synchronously with the spiral gear disk 9 through a bevel gear set 10.

[0040] Refer to Figure 4 and Figure 5, start the first motor 11. The output shaft of the first motor 11 drives the bevel gear set 10 to rotate. The bevel gear set 10 drives the spiral gear disk 9 to rotate. When the spiral gear disk 9 rotates, it drives the four jaws 8 to move simultaneously through the spiral teeth on its surface. According to the different directions of driving the spiral gear disk 9 to rotate, the four jaws 8 are driven to move towards the center of the mounting table 6 or towards both sides of the mounting table 6 simultaneously. By driving and controlling the position of the jaws 8 with the first motor 11, the picking and placing of the plate can be completed quickly.

[0041] Refer to Figure 5 , a second motor 12 is fixedly connected inside the chassis 1. The output shaft of the second motor 12 rotates synchronously with the mounting shaft 2 through the spur gear set 13.

[0042] Refer to Figure 5 , start the second motor 12. The output shaft of the second motor 12 rotates. The output shaft of the second motor 12 drives the spur gear set 13 to rotate. The spur gear set 13 drives the mounting shaft 2 to rotate. The mounting shaft 2 drives the mounting plate 3 to rotate, thereby driving the four groups of material fixing components to rotate, enabling the material fixing components to rotate around the mounting shaft 2 as the axis, and then replacing the positions of the four groups of material fixing components. The plate to be processed is sent to the bottom of the milling cutter for processing. Among them, when the auxiliary mechanism has four groups of material fixing components, each time the second motor 12 drives the mounting shaft 2 to rotate, the mounting shaft 2 is driven to rotate 90 degrees.

[0043] Refer to Figures 4 - 6 , a reciprocating lead screw 16 is fixedly connected to the bottom of the mounting table 6. A sleeve 14 is rotatably connected to the mounting plate 3. The reciprocating lead screw 16 passes through the sleeve 14. An internal thread disk 15 is fixedly connected to the top of the sleeve 14. The internal thread disk 15 is threadedly connected to the reciprocating lead screw 16. A rack 18 is fixedly connected inside the chassis 1. A first transmission gear 17 meshing with the rack 18 is fixedly connected to the bottom of the sleeve 14.

[0044] Refer to Figures 4 - 6 , while the mounting shaft 2 is rotating, the mounting shaft 2 drives the mounting plate 3 to rotate. When the mounting plate 3 rotates into the chassis 1, the first transmission gear 17 meshes with the rack 18. The rack 18 is stationary. The first transmission gear 17 makes a planetary rotation around the mounting shaft 2. When rotating, the rack 18 drives the first transmission gear 17 to rotate. The first transmission gear 17 drives the sleeve 14 to rotate. The sleeve 14 drives the internal thread disk 15 to rotate. The internal thread disk 15 drives the reciprocating lead screw 16 to move up and down. Moving up jacks up the material fixing components, facilitating the milling cutter to process the plate. And when the material fixing components are higher than the holes provided on the chassis 1 for the material fixing components to pass through, it prevents the flying objects inside the chassis 1 from reaching the staff through the side wall of the chassis 1, and at the same time avoids the milling cutter being flung and injuring the staff when the cutter breaks.

[0045] Refer to Figure 2, the rack 18 is arc-shaped. The first transmission gear 17 meshes with the head end of the rack 18 and disengages from the tail end of the rack 18. During this process, the internal thread disk 15 is driven to rotate, and the internal thread disk 15 then drives the reciprocating lead screw 16 to reciprocate up and down once.

[0046] Refer to Figures 2 - 4 , when the material fixing component rotates to the deepest part inside the chassis 1, that is, when it rotates to the position symmetrical to the feeding station, the reciprocating lead screw 16 rises to the highest position. When the first transmission gear 17 disengages from the rack 18, the reciprocating lead screw 16 drops to the limit position.

[0047] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 , a receiving box 20 is fixedly connected to the bottom of the chassis 1. An upwardly inclined discharge pipe 21 is fixedly connected to the side wall of the receiving box 20. A screw conveyor 22 is rotatably connected to the receiving box 20, and the screw conveyor 22 extends into the discharge pipe 21. A third motor 23 is fixedly connected to the outer wall of the receiving box 20, and the output shaft of the third motor 23 is fixedly connected to the screw conveyor 22.

[0048] During the process of the milling cutter machining the material, coolant (cutting fluid) is sprayed onto the workpiece. The coolant flushes away the metal chips generated during the machining process. The flushed metal chips and the coolant together fall into the receiving box 20 and sink to the bottom of the receiving box 20. Then, the third motor 23 is started. The third motor 23 drives the screw conveyor 22 to rotate. The screw conveyor 22 rotates to convey the metal chips sunk to the bottom of the receiving box 20 and transports them into the discharge pipe 21. As the metal chips in the discharge pipe 21 accumulate, the metal chips in the front are extruded out of the discharge pipe 21 by the metal chips in the back. Since the discharge pipe 21 is upwardly inclined, the coolant directly slides down into the receiving box 20 under the action of gravity and due to its strong fluidity, directly completing the separation of the metal chips and the coolant, facilitating the staff to collect the metal chips.

[0049] Refer to Figure 2 , a filter pipe 24 is rotatably connected inside the receiving box 20. One end of the filter pipe 24 extends outside the receiving box 20 and rotates synchronously with the output shaft of the third motor 23 through a belt pulley set 25.

[0050] Refer to Figure 2 , while the third motor 23 drives the screw conveyor 22 to rotate, the third motor 23 drives the filter pipe 24 to rotate through the belt pulley set 25, thereby shaking off the metal chips that fall on the filter pipe 24, thus preventing the filter holes on the filter pipe 24 from being blocked by the metal chips.

[0051] Refer to Figure 2 and Figure 3, a storage tank 26 for supplying coolant to the milling cutter inside the chassis 1 is fixedly connected to the side wall of the chassis 1, a piston cylinder 27 is fixedly connected to the bottom of the chassis 1, a piston plate 29 is slidably connected inside the piston cylinder 27, a piston rod 28 is rotatably connected to the piston plate 29, an eccentric gear 31 is rotatably connected inside the chassis 1, the piston rod 28 is rotatably connected to the eccentric gear 31, a second transmission gear 30 meshing with the eccentric gear 31 is fixedly connected to the mounting shaft 2, the output end of the piston cylinder 27 is connected to the storage tank 26 through a first water pipe 32, the piston cylinder 27 is fixedly connected with a second water pipe 33, the second water pipe 33 is rotatably connected to the filter pipe 24, and one-way valves are arranged on both the output end and the input end of the piston cylinder 27.

[0052] Referring to Figure 2 and Figure 3 , while the mounting shaft 2 is rotating, the mounting shaft 2 drives the second transmission gear 30 to rotate, the second transmission gear 30 drives the eccentric gear 31 to rotate, the eccentric gear 31 drives the piston plate 29 to reciprocate inside the piston cylinder 27 through the piston rod 28. When the piston plate 29 slides towards the eccentric gear 31, negative pressure is generated inside the piston cylinder 27. Under the action of the one-way valves at the output end and the input end of the piston cylinder 27, the negative pressure inside the piston cylinder 27 is transmitted into the second water pipe 33, and the negative pressure in the second water pipe 33 is then transmitted into the filter pipe 24, causing negative pressure to be generated in the filter pipe 24. As a result, the filter pipe 24 sucks the coolant in the material receiving box 20, the coolant is sucked into the filter pipe 24, then enters the second water pipe 33, and then enters the piston cylinder 27. When the piston plate 29 moves towards the end far from the eccentric gear 31, the coolant sucked into the piston cylinder 27 is squeezed into the first water pipe 32, and then is squeezed into the storage tank 26 through the first water pipe 32, realizing the recycling of the coolant, saving the coolant, and reducing the processing cost.

[0053] Referring to Figure 2 , a cleaning brush 34 is fixedly connected to the inner wall of the material receiving box 20, and the cleaning brush 34 abuts against the outer wall of the filter pipe 24.

[0054] Referring to Figure 2 , when the filter pipe 24 is rotating, the cleaning brush 34 scrapes the surface of the filter pipe 24, cleaning the metal debris on the surface of the filter pipe 24, thereby preventing the filter holes of the filter pipe 24 from being blocked. The cleaning brush 34 is preferably a brush to prevent the surface of the filter pipe 24 from being scratched.

[0055] The usage process of the present invention is as follows: Start the first motor 11 on the placement station. The output shaft of the first motor 11 drives the bevel gear set 10 to rotate. The bevel gear set 10 drives the spiral gear disk 9 to rotate. When the spiral gear disk 9 rotates, it drives the four jaws 8 to move towards the edge position of the mounting table 6 simultaneously through the spiral teeth on its surface, opening the four jaws 8 simultaneously. Then start the first motor 11 again to drive the four jaws 8 on the workbench to move towards the center of the mounting table 6 simultaneously to fix the workpiece. Then start the second motor 12. The output shaft of the second motor 12 rotates. The output shaft of the second motor 12 drives the spur gear set 13 to rotate. The spur gear set 13 drives the mounting shaft 2 to rotate. The mounting shaft 2 drives the mounting plate 3 to rotate by 90 degrees. Then place the workpiece on the workbench outside the chassis 1 after rotation. Repeat the operation. The self-made material fixing component with the plate moves to the lower part of the milling cutter. Then start the control system with the milling cutter to process the plate. After the processing is completed, start the second motor 12 to move it outside the chassis 1 and replace the workpiece. While replacing the workpiece, the milling cutter processes the plates on other stations, thus realizing continuous processing and improving the processing efficiency.

[0056] The present invention is provided with multiple groups of material fixing components and installs the material fixing components on a rotating disk, which improves the efficiency of workpiece replacement while maintaining the stability of the workpiece during processing, thereby avoiding the displacement of the workpiece during processing and further avoiding the reduction of processing accuracy.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
