Description

Technical Field

[0001] This invention relates to the field of composite machine tool technology, specifically to a single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center and method. Background Technology

[0002] The single-sided horizontal boring and milling gantry machining center is a core piece of equipment in the field of heavy-duty precision machining. It is specifically designed for the efficient and precision machining of large and extra-large box-shaped, frame-shaped, and beam-shaped parts. Its core advantage lies in integrating single-sided horizontal boring and milling functions. Equipped with a high-precision spindle unit, heavy-duty linear guides, and a CNC indexing table, it can complete multiple processes such as boring, milling, drilling, and tapping in one operation, significantly reducing the number of workpiece clamping operations and avoiding repeated positioning errors.

[0003] Referring to the patent application CN116276094B, a gantry-type turning-boring-milling composite flexible machining unit is disclosed. By incorporating a gantry-type boring-milling machining center, a floor-type boring-milling machining center, and a horizontal turning-milling machining center, the composite flexible machining unit can complete the machining process of large workpieces after clamping and fixing them according to different machining requirements, effectively improving the positional accuracy and efficiency of machining. By setting up a chip removal mechanism, chips wrapped around the boring bar can be cleaned during rough boring in the floor-type boring-milling machining center, effectively improving the convenience of chip removal without stopping the machine, further enhancing the efficiency of the flexible machining unit. The use of a hook tube further improves the chip removal mechanism's cleaning effect on the external chips of the boring bar by hooking the chips.

[0004] Although the chip removal mechanism in the aforementioned patent can remove chips from the outside of the boring tool during the machining process, the chips still remain scattered on the machining table. In addition to some granular chips, the machining chips also contain a large number of spiral chips, long and tight spiral chips, and ribbon chips. These metal chips will pad the workpiece and the worktable, forming irregular gaps, which prevents the workpiece from being fully fitted and positioned. Furthermore, the accumulated chips will produce an "elastic support" effect during the cutting process, causing the tool to fluctuate under force and trigger chatter, which in turn reduces the machining accuracy of the workpiece or even damages the tool.

[0005] Secondly, in order to avoid reducing the machining accuracy of the workpiece, operators need to frequently stop the machine to clean the debris on the table. Each cleaning takes several minutes, which accumulates to a large amount of effective processing time during batch production. If the amount of debris is large, the cleaning time needs to be extended, further extending the downtime and reducing processing efficiency.

[0006] Therefore, this invention proposes a single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center and method to solve the above problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a single-sided horizontal boring and milling composite machining center and method. It solves the problem that current chip removal mechanisms in boring and milling composite machining centers can only clean chips outside the boring tool, leaving chips scattered on the machining table. Because these chips contain a large amount of spiral chips, long and tight spiral chips, and ribbon-like chips, they easily accumulate between the workpiece and the table, forming irregular gaps. This prevents the workpiece from being fully fitted and positioned. Furthermore, the accumulated chips create an "elastic support" effect, causing fluctuations in tool force and chatter, which reduces workpiece machining accuracy and may damage the tool. Frequent machine stops for chip removal not only consume a significant amount of effective machining time during batch production but also require extended cleaning time when the chip volume is large, further reducing machining efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a single-sided horizontal boring and milling composite machining center with a fixed beam, comprising a boring and milling composite support and slide rails fixedly disposed on both sides of its outer wall. A position control component for adjusting the boring and milling composite machining position is commonly sleeved on the outer wall of the two slide rails. The position control component is provided with a boring and milling composite machining device for performing boring and milling composite machining operations on the workpiece. The top of the boring and milling composite support is also provided with a bearing mechanism for supporting the workpiece to be boring and milled.

[0009] The bearing mechanism can switch between different horizontal support zones before processing different workpieces to further concentrate the metal scrap initially collected at the top. Simultaneously, while switching the horizontal support zones, multiple scrap collection components hook up longer spiral scrap, long and tightly coiled scrap, and ribbon-like scrap, and cut the long scrap into multiple small pieces for centralized collection. This reduces the space occupied by loose scrap and accelerates the removal of cutting fluid.

[0010] Below each of the waste chip collection components, there is also a metal chip pushing component that works in conjunction with it to perform directional intermittent pushing of waste chips. The metal chip pushing component pushes the collected metal chips directionally by using the power intermittent when the waste chip collection component switches the horizontal support area, so as to ensure that the metal chips are pushed out while extending the residence time in the support mechanism and improving the removal rate of cutting fluid.

[0011] Furthermore, the position control component includes two side plates that are slidably sleeved on the outer walls of two slide rails respectively. A transverse linear module for controlling the lateral position of the boring and milling composite machining equipment is fixedly arranged between the opposite side walls of the two side plates. A longitudinal linear module for controlling the longitudinal height of the boring and milling composite machining equipment is also arranged on the transverse linear module. A drive plate is fixedly arranged at the bottom of the two side plates. A second servo motor is also fixedly arranged on the outer wall of the boring and milling composite bracket. A lead screw is connected to the output shaft of the second servo motor through a coupling. The drive plate is threaded onto the outer wall of the lead screw.

[0012] Furthermore, the supporting mechanism includes an upper box fixedly installed on the top of the boring and milling composite support. The top of the upper box is evenly provided with multiple preliminary waste chip collection channels. The waste chip gathering component is arranged in the waste chip collection space formed by the multiple preliminary waste chip collection channels in the same row. At the bottom of the inner cavity of the upper box and at the position opposite to the same row of preliminary waste chip collection channels, there is a metal chip separation channel for collecting shredded metal chips. The bottom of the metal chip separation channel is evenly provided with multiple cutting fluid filter holes. The metal chip separation channel is also provided with a metal chip pushing component for pushing out the metal chips drained from the cutting fluid in cooperation with the waste chip gathering component. The side wall of the upper box is provided with metal chip outlets corresponding to the positions of the multiple metal chip separation channels. A collection box for receiving metal chips is fixedly installed on the side wall of the upper box and below the multiple metal chip outlets.

[0013] Furthermore, a lower housing is fixedly installed at the bottom of the upper housing. The lower housing has a conical structure, and a chip removal pipe connected to its interior is fixedly installed at the lowest point of the lower housing. The chip removal pipe is connected to the cutting fluid collection tank through a pipe. A power component for simultaneously driving multiple waste chip collection components is also installed on the side wall of the upper housing. The power component includes a first servo motor fixedly installed on the outer wall of the upper housing. A second transmission shaft is fixedly installed on the output shaft of the first servo motor. Multiple worm gears corresponding to the positions of the waste chip collection components are evenly fixedly installed on the outer wall of the second transmission shaft.

[0014] Furthermore, the waste collection assembly includes a first drive shaft rotatably disposed inside the upper housing. One end of the first drive shaft is also fixedly provided with a worm wheel that meshes with a worm gear at a corresponding position. Multiple cutting units are uniformly sleeved on the outer wall of the first drive shaft, and each cutting unit is respectively disposed in one of the waste preliminary collection channels.

[0015] Furthermore, the hooking unit includes a knife holder fixedly sleeved on the outer wall of the first drive shaft. Multiple mounting slots are evenly provided on the outer wall of the knife holder. An L-shaped hook knife is detachably installed in each mounting slot by bolts. The end of the L-shaped hook knife is provided with a horizontal support area for supporting the workpiece, and multiple blades are evenly provided on the inner wall of each L-shaped hook knife.

[0016] Furthermore, the metal chip pushing assembly includes a push-pull rod that slides through the upper box. A spring baffle is fixedly installed at one end of the push-pull rod and outside the upper box. A return spring is slidably sleeved on the outer wall of the push-pull rod between the spring baffle and the upper box. Multiple push plate units are uniformly sleeved on the outer wall of the push-pull rod.

[0017] Furthermore, the pusher unit includes a pusher plate slidably disposed in the metal chip separation groove. A movable groove is provided on the side wall of the pusher plate. A rotating shaft is rotatably disposed on the inner wall of the movable groove. A drive arm is fixedly sleeved on the outer wall of the rotating shaft. A limit plate is fixedly disposed at the bottom end of the drive arm. The bottom end of the limit plate abuts against the inner wall of the movable groove, allowing the pusher plate to rotate around the rotating shaft in only one direction.

[0018] Furthermore, a control box is also provided on one side of the boring and milling composite support for controlling the operation of all electrical equipment.

[0019] This invention also discloses a single-sided horizontal boring and fixed-beam gantry boring and milling composite machining method for a single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center. The method includes the following steps:

[0020] Step 1: First, place the workpiece to be processed on top of the support mechanism, and then lock the workpiece.

[0021] Step 2: Adjust the position of the boring and milling composite machining equipment from the workpiece by controlling the position adjustment component through the control box. After reaching the machining position, perform boring, milling, or a combination of boring and milling operations.

[0022] Step 3: After a single workpiece is processed, it is removed and the load-bearing mechanism is switched to the horizontal support area. At the same time, the metal scraps scattered on the top of the load-bearing mechanism are hooked into the interior of the load-bearing mechanism and shredded. The shredded metal scraps enter the load-bearing mechanism and the cutting fluid on the surface is naturally drained. The cutting fluid is then collected after filtration.

[0023] Step 4: The bearing mechanism completes the switching operation of the horizontal support area, then repositions and fixes the workpiece, and performs the boring operation again.

[0024] This invention provides a single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center and method. Compared with the prior art, it has the following advantages:

[0025] 1. A single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center and method, addressing the pain points of traditional machining centers where long waste chips such as spiral curls, long and tight curls, and ribbon-like chips easily entangle the equipment, block the collection channel, and occupy a large amount of collection space due to their fluffy state. This application adopts a "horizontal support area switching + hooking and cutting integration" design. That is, when the waste chip collection component switches the horizontal support area, the L-shaped hook cutter actively hooks the surrounding long waste chips with the hook-like structure of the horizontal support area, and then cuts them into small pieces by the inner wall blades. This completely solves the industry pain points of long chips being difficult to collect and easily entangled. It realizes the integrated design of horizontal support area switching and waste chip hooking, pushing, and collection processes. After the workpiece is processed, the waste chip cleaning can be completed at the same time as switching the horizontal support area, without the need for additional machine downtime for cleaning. The process significantly improves processing time and cycle time, making it particularly suitable for mass production scenarios. The increased chip density after slitting significantly reduces the occupancy rate of the collection space and the frequency of chip cleaning. Furthermore, the initial chip collection channel at the top of the upper housing allows small chips to slide directly down, while larger, longer chips are squeezed and cut by the blades during the rotation of the cutting unit. Larger chips that are not completely shredded are further cut during subsequent switching of the horizontal support zone until the particle size meets the channel gap requirements, ensuring that all chips can smoothly enter the separation tank. This prevents chips from remaining in the horizontal support zone and affecting workpiece positioning accuracy. Uniformly sized chips not only facilitate pushing and collecting but also prevent large chips from clogging the collection channel, laying the foundation for the transport of metal chips and the rapid recovery of cutting fluid.

[0026] 2. A single-sided horizontal boring and fixed-beam gantry milling composite machining center and method, which links a metal chip pushing component and a waste chip collection component. The metal chip pushing component intermittently pushes chips using the power of switching horizontal support zones. The pusher unit achieves directional movement through the cooperation of a limit plate and a rotating shaft, i.e., it maintains vertical pushing when pushing metal chips and rotates to avoid chip accumulation during resetting, ensuring that chips continuously move towards the output port without requiring machine stoppage for cleaning, thus guaranteeing continuous processing. Moreover, the metal chip output port corresponds one-to-one with the collection box, and the shredded chips fall into the collection box. Operators only need to clean the collection box periodically, eliminating the need for... The deep cleaning of the equipment interior significantly reduces labor intensity. Secondly, the intermittent pushing design of the metal chip pushing component significantly extends the residence time of chips in the metal chip separation tank. Combined with the filter holes at the bottom of the separation tank, the cutting fluid is fully separated from the chips under gravity, solving the resource waste problem caused by cutting fluid entrainment in traditional collection methods. The recovered cutting fluid can be recycled, reducing processing costs. In addition, the metal chip pushing component is driven by the rotational power of the waste chip gathering component when switching the horizontal support area. The intermittent pushing is achieved through the return spring, eliminating the need for an additional power source, simplifying the equipment structure, and thus facilitating subsequent inspection and maintenance.

[0027] 3. A single-sided horizontal boring and milling composite machining center and method, which adopts a split design between the L-shaped hook cutter and the tool holder. The L-shaped hook cutter is detachably installed in the mounting groove of the tool holder by bolts. When the cutting tool is worn or needs to be adapted to different types of waste chips, the hook cutter can be replaced separately without disassembling the entire waste chip collection assembly, thus reducing maintenance difficulty and cost. Secondly, the four L-shaped hook cutters of the hook cutting unit alternately serve as horizontal support areas, and can be switched by rotating 90° each time. The spacing and bearing area of ​​the horizontal support areas can be adapted to workpieces of different sizes and shapes by adjusting the number or specifications of the hook cutters, thereby improving the versatility of the equipment.

[0028] 4. A single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center and method, wherein multiple waste chip collection channels are evenly arranged on the top of the upper housing to form multiple rows of collection channels, which are adapted to the large processing area of ​​the gantry machining center, ensuring that waste chips generated at different processing positions can be collected in a timely manner, avoiding local waste chip accumulation, thereby automatically and efficiently cleaning metal chips generated during boring and milling processes; secondly, the single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center realizes the simultaneous processing of waste chips and cutting fluid recovery during the processing through the integrated design of the bearing mechanism, which simplifies the equipment layout and reduces the equipment purchase and installation costs, and is especially suitable for high-precision, large-volume boring and milling composite machining scenarios.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] This invention provides two technical solutions: a single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center, specifically including the following embodiments:

[0047] like Figures 1-5 The first embodiment is shown: a single-sided horizontal boring and milling composite machining center with fixed beam, including a boring and milling composite support 1 and slide rails 2 fixedly installed on both sides of its outer wall. The outer walls of the two slide rails 2 are jointly fitted with a position control component for adjusting the boring and milling composite machining position. The position control component is equipped with a boring and milling composite machining device 6 for performing boring and milling composite machining operations on the workpiece. The top of the boring and milling composite support 1 is also equipped with a bearing mechanism 7 for supporting the workpiece to be boring and milled.

[0048] The bearing mechanism 7 can switch between different horizontal support zones before machining different workpieces to further concentrate the metal scrap initially collected at the top. Simultaneously, while switching horizontal support zones, multiple scrap collection components 73 hook up longer spiral scrap, long and tight scrap, and ribbon-like scrap, and cut the long scrap into multiple small pieces for centralized collection. This reduces the space occupied by loose scrap and accelerates the removal of cutting fluid.

[0049] Below each waste chip collection component 73, there is also a metal chip pushing component 75 that works in conjunction with it to perform directional intermittent pushing of waste chips. The metal chip pushing component 75 pushes the collected metal chips directionally by intermittently pushing them with the power of the waste chip collection component 73 when switching the horizontal support area, so as to ensure that the metal chips are pushed out while extending the residence time in the support mechanism 7 and improving the removal rate of cutting fluid.

[0050] In this embodiment, a control box 8 is also provided on one side of the boring and milling composite bracket 1 to control the operation of all electrical equipment.

[0051] In this embodiment, the position control component includes two side plates 3 that are slidably sleeved on the outer walls of two slide rails 2. A transverse linear module 4 for controlling the transverse position of the boring and milling composite machining equipment 6 is fixedly arranged between the opposite side walls of the two side plates 3. A longitudinal linear module 5 for controlling the longitudinal height of the boring and milling composite machining equipment 6 is also arranged on the transverse linear module 4. A drive plate 11 is fixedly arranged at the bottom of the two side plates 3. A second servo motor 9 is also fixedly arranged on the outer wall of the boring and milling composite support 1. A lead screw 10 is connected to the output shaft of the second servo motor 9 through a coupling. The drive plate 11 is threaded onto the outer wall of the lead screw 10.

[0052] Addressing the pain points of traditional machining centers where long, tightly rolled, and ribbon-like chips easily entangle and clog collection channels, and their fluffy nature occupies significant collection space, this application employs a "horizontal support zone switching + integrated hooking and cutting" design. Specifically, when switching horizontal support zones, the L-shaped hook 7333 of the chip collection component 73 actively hooks surrounding long chips using the hook-like structure of the horizontal support zone 7335. The inner wall blade 7334 then cuts these chips into smaller fragments, completely resolving the industry pain points of difficult chip collection and easy entanglement. This integrated design achieves horizontal support zone switching with chip hooking, pushing, and collection. After workpiece processing, chip cleaning can be completed simultaneously with switching horizontal support zones, eliminating the need for additional downtime for cleaning and significantly improving processing cycle time. Especially suitable for mass production scenarios; the increased chip density after slitting significantly reduces the occupancy rate of collection space and the frequency of chip cleaning; secondly, the chip collection channel 72 at the top of the upper box 71 allows small chips to slide directly down, while large long chips are squeezed and cut by the blade 7334 through the gap when the hook-cutting unit 733 rotates. Larger chips that are not completely shredded will be cut again when the horizontal support area is switched later, until the particle size meets the channel gap requirements, ensuring that all chips can smoothly enter the metal chip separation tank 74, avoiding chip residue in the horizontal support area that affects the workpiece positioning accuracy. The uniform chip size not only facilitates pushing and collection, but also prevents large chips from clogging the collection channel, laying the foundation for the transportation of metal chips and the rapid recovery of cutting fluid.

[0053] like Figures 6-14 The second embodiment is shown, which differs from the first embodiment in that: the supporting mechanism 7 includes an upper box 71 fixedly mounted on the top of the boring and milling composite support 1. The top of the upper box 71 has a plurality of preliminary waste chip collection channels 72 evenly distributed. The waste chip collection assembly 73 is disposed within a waste chip collection space formed by the same row of preliminary waste chip collection channels 72. Metal chips for collecting shredded metal fragments are provided at the bottom of the inner cavity of the upper box 71 and at positions opposite to the same row of preliminary waste chip collection channels 72. The metal chip separation tank 74 has multiple cutting fluid filter holes evenly distributed at its bottom. A metal chip pushing component 75, which works in conjunction with the waste chip collection component 73 to push out metal chips drained of cutting fluid, is also provided inside the metal chip separation tank 74. Metal chip outlets 78, corresponding one-to-one with the positions of the multiple metal chip separation tanks 74, are provided on the side wall of the upper housing 71. A collection box 79 for receiving metal chips is fixedly installed on the side wall of the upper housing 71, below the multiple metal chip outlets 78. The cutting fluid filter holes are connected to the interior of the lower housing 76.

[0054] Multiple waste chip collection channels 72 are evenly arranged on the top of the upper housing 71 to form multiple collection channels, which are suitable for the large processing area of ​​the gantry machining center. This ensures that waste chips generated at different processing positions can be collected in a timely manner, avoiding local waste chip accumulation. This enables automatic and efficient cleaning of metal chips generated during boring and milling processes. Secondly, this single-sided horizontal boring fixed beam gantry boring and milling composite machining center achieves simultaneous waste chip treatment and cutting fluid recovery during the processing through the integrated design of the load-bearing mechanism 7. This simplifies the equipment layout and reduces the equipment purchase and installation costs, making it particularly suitable for high-precision, high-volume boring and milling composite machining scenarios.

[0055] In this embodiment, a lower housing 76 is fixedly installed at the bottom of the upper housing 71. The lower housing 76 has a conical structure, and a chip removal pipe 77 connected to its interior is fixedly installed at the lowest point of the lower housing 76. The chip removal pipe 77 is connected to the cutting fluid collection tank via a pipe. A power assembly for simultaneously driving multiple waste chip collection components 73 is also installed on the side wall of the upper housing 71. The power assembly includes a first servo motor 710 fixedly installed on the outer wall of the upper housing 71. A second transmission shaft 711 is fixedly installed on the output shaft of the first servo motor 710. Multiple worm gears 712, corresponding one-to-one with the positions of the waste chip collection components 73, are evenly fixedly installed on the outer wall of the second transmission shaft 711. The height of the chip removal pipe 77 is above the drive plate 11, so it will not interfere with the movement of the drive plate 11.

[0056] In this embodiment, the waste collection assembly 73 includes a first drive shaft 731 rotatably disposed inside the upper housing 71. One end of the first drive shaft 731 is also fixedly provided with a worm wheel 732 that meshes with the worm gear 712 at the corresponding position. Multiple cutting units 733 are uniformly sleeved on the outer wall of the first drive shaft 731, and each cutting unit 733 is respectively disposed in one of the waste preliminary collection channels 72.

[0057] By linking the metal chip pushing component 75 and the waste chip collecting component 73, the metal chip pushing component 75 intermittently pushes the chips with the help of the switching power of the horizontal support area 7335. The push plate unit 754 achieves directional movement through the cooperation of the limit plate 7545 and the rotating shaft 7543. That is, it keeps the pusher vertically when pushing metal chips and rotates to avoid chip accumulation when resetting, thus preventing the chips from falling back and accumulating. This ensures that the chips continuously move towards the output port without the need to stop the machine for cleaning, thereby ensuring the continuity of processing. Moreover, the metal chip output port 78 corresponds one-to-one with the collection box 79. The shredded chips fall into the collection box 79 in a concentrated manner. The operator only needs to clean the collection box 79 periodically without having to go deep into the equipment for cleaning. Firstly, the intermittent pushing design of the metal chip pushing component 75 significantly extends the residence time of chips in the metal chip separation tank 74. Combined with the filter holes at the bottom of the metal chip separation tank 74, the cutting fluid is fully separated from the chips under gravity, solving the resource waste problem caused by cutting fluid entrainment in traditional collection methods. The recovered cutting fluid can be recycled, reducing processing costs. Secondly, the metal chip pushing component 75 is driven by the rotational power of the waste chip gathering component when switching the horizontal support area 7335, and intermittent pushing is achieved through the return spring 753. No additional power source is required, simplifying the equipment structure and facilitating subsequent inspection and maintenance.

[0058] In this embodiment, the hook-cutting unit 733 includes a knife holder 7331 fixedly sleeved on the outer wall of the first drive shaft 731. The outer wall of the knife holder 7331 is evenly provided with a plurality of mounting grooves 7332. Each mounting groove 7332 is detachably provided with an L-shaped hook knife 7333 by bolts. The end of the L-shaped hook knife 7333 is provided with a horizontal support area 7335 for supporting the workpiece. And the inner wall of each L-shaped hook knife 7333 is evenly provided with a plurality of blades 7334.

[0059] Through the split design between the L-shaped hook blade 7333 and the blade holder 7331, the L-shaped hook blade 7333 is detachably installed in the mounting slot 7332 of the blade holder 7331 using bolts. When the blade 7334 is worn or needs to be adapted to different types of waste chips, the hook blade can be replaced separately without disassembling the entire waste chip collection assembly 73, reducing maintenance difficulty and cost. Secondly, the four L-shaped hook blades 7333 of the hook cutting unit 733 alternately serve as horizontal support areas 7335, which can be switched by rotating 90° each time. The spacing and bearing area of ​​the horizontal support areas 7335 can be adapted to workpieces of different sizes and shapes by adjusting the number or specifications of the hook blades, improving the versatility of the equipment.

[0060] In this embodiment, the metal chip pushing assembly 75 includes a push-pull rod 751 that slides through the upper housing 71. A spring baffle 752 is fixedly installed at one end of the push-pull rod 751 and located outside the upper housing 71. A return spring 753 is slidably sleeved on the outer wall of the push-pull rod 751 and located between the spring baffle 752 and the upper housing 71. A plurality of push plate units 754 are evenly sleeved on the outer wall of the push-pull rod 751.

[0061] In this embodiment, the pusher unit 754 includes a pusher 7541 slidably disposed within the metal chip separation groove 74. A movable groove 7542 is formed on the side wall of the pusher 7541. A rotating shaft 7543 is rotatably disposed on the inner wall of the movable groove 7542. A drive arm 7544 is fixedly sleeved on the outer wall of the rotating shaft 7543. A limiting plate 7545 is fixedly disposed at the bottom end of the drive arm 7544. The bottom end of the limiting plate 7545 abuts against the inner wall of the movable groove 7542, allowing only the pusher 7541 to rotate around the rotating shaft 7543. When the drive arm 7544 is rotated in one direction, a hemispherical protrusion is fixedly installed on the upper side wall. When the tool holder 7331 rotates, it can push the hemispherical protrusion to move a fixed distance, thereby pushing the drive arm 7544 to move in a directional manner. When the push plate 7541 moves away from the spring baffle 752, the push plate unit 754 is limited by the limiting plate 7545 and cannot rotate around the rotating shaft 7543. When it is reset, it loses the limiting effect of the limiting plate 7545 and rotates, thus achieving the purpose of directionally pushing the metal scrap to move.

[0062] This invention also provides a single-sided horizontal boring and fixed-beam gantry boring and milling composite machining method for use in a single-sided horizontal boring and fixed-beam gantry boring and milling composite machining center. The method includes the following steps:

[0063] Step 1: First, place the workpiece to be processed on top of the bearing mechanism 7, and then lock the workpiece;

[0064] Step 2: Adjust the position of the boring and milling composite machining equipment 6 from the workpiece by controlling the position adjustment component through the control box 8. After reaching the machining position, perform boring, milling, or a combination of boring and milling operations.

[0065] Step 3: After a single workpiece is processed, it is removed and the load-bearing mechanism 7 is switched to the horizontal support area. At the same time, the metal scraps scattered on the top of the load-bearing mechanism 7 are hooked into the interior of the load-bearing mechanism 7 and shredded. The shredded metal scraps enter the load-bearing mechanism 7 and the cutting fluid on the surface is naturally drained. The cutting fluid is collected after filtration.

[0066] Step 4: The bearing mechanism 7 completes the switching operation of the horizontal support area, then repositions and fixes the workpiece, and performs the boring operation again.

[0067] The specific process is as follows: First, the hooking units 733 in multiple waste chip collection components 73 jointly form a horizontal support area for supporting the workpiece to be processed. The L-shaped hooks 7333 in the hooking unit 733 are composed of four evenly distributed L-shaped hooks 7333. In the initial state, the top of the horizontal support area 7335 of one of the L-shaped hooks 7333 is facing upward. Each time the first drive shaft 731 rotates ninety degrees, that is, each time the tool holder 7331 rotates once, the adjacent two L-shaped hooks 7333 alternate positions.

[0068] Next, the workpiece to be processed is placed on the horizontal support area of ​​multiple L-shaped hook cutters 7333, and the workpiece is fixed by a fixture. At this time, the second servo motor 9 is controlled by the control box 8 to drive the lead screw 10 to rotate. The drive plate 11 slides along the outer wall of the lead screw 10 under the thread drive of the lead screw 10. Then, the control box 8 controls the operation of the horizontal linear module 4 and the vertical linear module 5 according to the preset program, so as to control the boring and milling compound processing equipment 6 to move in the horizontal and vertical directions, so that the boring and milling compound processing equipment 6 reaches the boring and milling working position and performs the boring and milling compound processing of the workpiece. The metal chips generated during the boring and milling process fall to the top of the upper box 71 under the action of gravity.

[0069] Because the top of the upper housing 71 is equipped with multiple adjacent preliminary waste chip collection channels 72, smaller metal chips slide directly into the preliminary waste chip collection channels 72 and fall directly into the metal chip pushing assembly 75 located directly below through the gap between the preliminary waste chip collection channels 72 and the cutting unit 733. The cutting fluid adhering to the surface of the metal chips gradually separates under the action of gravity and flows into the lower housing 76 through the cutting filter holes on the surface of the metal chip separation channel 74. However, larger screw chips, long and tight screw chips, and ribbon-like chips accumulate around the preliminary waste chip collection channels 72. After the current workpiece is processed and disassembled, the output shaft of the first servo motor 710 is rotated by a preset angle via the control box 8. Multiple worm gears 712, fixedly mounted on the second transmission shaft 711, drive the corresponding worm wheels 732 to rotate 90 degrees. Then, the output shaft of the first servo motor 710 is automatically locked. Simultaneously, multiple tool holders 7331 rotate 90 degrees synchronously. During this process, due to the hook-shaped shape of the horizontal support area 7335, the horizontal support area 7335 automatically catches surrounding threaded chips, long and tight threads, and ribbon-like chips during its swing, and initially collects this portion of metal waste. The internal pulling of the through groove 72 causes the screw coils, long and tight screw coils, and ribbon-shaped chips to enter the waste chip preliminary collection through groove 72. Due to the small gap between the waste chip preliminary collection through groove 72 and the cutting unit 733, the larger screw coils, long and tight screw coils, and ribbon-shaped chips cannot pass through. When the horizontal support area 7335 continues to rotate and apply force, the screw coils, long and tight screw coils, and ribbon-shaped chips are cut by the blades 7334 set on the surface of the horizontal support area 7335. Some of the shredded metal chips fall into the metal chip separation groove 74 through the gap between the waste chip preliminary collection through groove 72 and the cutting unit 733. The other part... Larger metal chips that fail to pass through remain in the initial chip collection channel 72. When the cutting unit 733 rotates and switches to the horizontal support area, these metal chips are cut again. The metal chips that are reduced in size fall into the metal chip separation channel 74 through the gap between the initial chip collection channel 72 and the cutting unit 733. The cutting fluid adhering to the surface of the metal chips gradually separates from its surface under the action of gravity and enters the lower box 76 through the cutting fluid filter hole at the bottom of the metal chip separation channel 74. Finally, it flows into the cutting fluid collection tank through the chip discharge pipe 77.

[0070] While the hook-cutting unit 733 rotates to switch to the horizontal support area, the drive arm 7544 in the push plate unit 754, which is positioned corresponding to the hook-cutting unit 733, is pushed by the side wall of the hook-cutting unit 733 and moves away from the spring baffle 752. At this time, the inner wall of the movable groove 7542 is limited by the limiting plate 7545 and remains vertical. At this time, the push-pull rod 751 moves synchronously with multiple push plate units 754 in the same direction, the return spring 753 is compressed and undergoes elastic deformation, and the metal chips located in the metal chip separation groove 74 are gradually pushed towards the metal chip output port 78. When the hook-cutting unit 733 rotates to the gap between two adjacent L-shaped hooks 7333, the drive arm 7544 moves away from the spring baffle 752. When the wall loses its driving force, the elastic force of the return spring 753 pushes the push-pull rod 751 to reset. When the push plate 7541 moves towards the return spring 753, the inner wall of the movable groove 7542 loses the pushing force of the limit plate 7545. The side wall of the push plate 7541 near the movable groove 7542 is blocked by metal debris and rotates around the rotating shaft 7543 to avoid pushing the metal debris back again. Under the repeated pushing of the push plate 7541, the metal debris gradually approaches the metal debris output port 78 and finally enters the collection box 79. At this time, the staff can directly clean the metal debris in the collection box 79 without stopping the machine. At the same time, the shredded metal debris is more compacted, making it easier for the staff to clean.
