Description

Technical Field

[0001] This invention relates to the field of CNC machine tools, and in particular to a composite machining machine tool. Background Technology

[0002] With the rapid development of modern industry, the requirements for the types, shapes, precision, and efficiency of processed materials are constantly increasing, placing higher demands on machine tools. Material processing often involves multiple steps, and the specialized nature of traditional machine tools means that each step must be completed on multiple machine tools. Multiple clamping operations affect processing quality and precision, making it difficult to guarantee processing efficiency. Therefore, composite machine tools that integrate laser processing and tool processing are constantly being developed.

[0003] A composite machining center includes a laser processing mechanism, a tool processing mechanism, a worktable that slides along the X-axis, and an X-axis drive mechanism that drives the worktable. Taking the tool processing mechanism as an example, it mainly includes a gantry fixedly mounted on the machine bed, a Y-axis saddle slidably mounted on the gantry, a Y-axis drive mechanism for driving the Y-axis saddle, a spindle box slidably mounted on the Y-axis saddle, a Z-axis drive mechanism for driving the spindle box along the Z-axis, and a tool spindle mounted on the spindle box. In reality, CNC machine tools are only partially assembled before shipment from the factory. The X-axis drive mechanism, Y-axis drive mechanism, and Z-axis drive mechanism are not yet connected to their corresponding components. Therefore, the laser processing mechanism, tool processing mechanism, and worktable will shake violently during transport, and may even collide with the machine bed, causing damage. This makes it difficult to ensure the working performance of the tool spindle and laser assembly after arrival at the destination. Therefore, to protect the tool spindle and laser assembly, it is essential to secure the laser processing mechanism, tool processing mechanism, and worktable before transporting the laser machining center.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

Detailed Implementation

[0026] This invention provides a composite machining tool. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0027] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0028] Please see Figures 1 to 2 As shown, the present invention provides a composite machining tool, including a bed 1, a first gantry 21 and a second gantry 31 arranged front to back on the bed 1, a worktable 41 slidably mounted on the bed 1, an X-axis drive mechanism 42 for driving the worktable 41 to move back and forth, and the first gantry 21 and the second gantry 31 fixed on the bed 1 and passing through the movement path of the worktable 41; a first Y-axis slide saddle 22 and a first Y-axis drive mechanism 23 for driving the first Y-axis slide saddle 22 to move left and right are slidably mounted on the first Y-axis slide saddle 22, a Z-axis slide saddle 24 and a first Z-axis drive mechanism 26 for driving the Z-axis slide saddle 24 to move up and down are slidably mounted on the first Y-axis slide saddle 22, and a laser assembly 25 is provided on the Z-axis slide saddle 24; the second gantry 31 is slidably mounted on the first Y-axis slide saddle 22. The machine tool is provided with a second Y-axis slide saddle 32 and a second Y-axis drive mechanism 33 for driving the second Y-axis slide saddle 32 to move left and right. A spindle box 34 is slidably mounted on the second Y-axis slide saddle 32 and a second Z-axis drive mechanism 36 for driving the spindle box 34 to move up and down. A vertically extending tool spindle 35 is provided on the spindle box 34. The axis of the tool spindle 35 extends vertically and the output end of the tool spindle 35 extends from the bottom of the spindle box 34. A protective frame 5 is installed at the bottom of the spindle box 34 to surround the output end of the spindle box 34. The protective frame 5 is clamped on the worktable 41. A stop seat 74 for limiting the sliding of the worktable 41 is installed on the bed 1. A fixed bracket 6 is installed on the bed 1. The bottom of the Z-axis slide saddle 24 is connected to the fixed bracket 6.

[0029] The composite machining tool provided by the present invention adopts a double gantry structure layout, which forms two machining stations below the tool spindle 35 and the laser assembly 25 respectively. The worktable 41 runs along the X-axis and reaches the laser machining station and the tool machining station respectively according to the machining requirements. Milling and laser machining can be completed in one clamping, thereby reducing clamping errors caused by disassembling the workpiece and improving machining accuracy and efficiency.

[0030] When the composite machining center is shipped, the sliding assembly of the first Y-axis slide saddle 22 and the Z-axis slide saddle 24, as well as the sliding assembly of the second Y-axis slide saddle 32 and the spindle box 34, have been completed. However, the first Y-axis drive mechanism 23, the second Y-axis drive mechanism 33, the first Z-axis drive mechanism 26, and the second Z-axis drive mechanism 36 require transmission debugging after the composite machining center is transported to its destination. Since they do not form a drive connection with their corresponding components, both the first Y-axis slide saddle 22 and the second Y-axis slide saddle 32 can move freely along the Y-axis, and both the Z-axis slide saddle 24 and the spindle box 34 can move automatically along the Z-axis. The spindle box 34 is equipped with a tool spindle 35, and the output end of the tool spindle 35 extends from the bottom of the spindle box 34. To prevent the spindle box 34 from moving on its own during transportation and to prevent damage to the tool spindle 35, a protective frame 5 is installed at the bottom of the spindle box 34 before shipment. This protects the output end of the tool spindle 35. Then, by moving the second Y-axis slide 32, the spindle box 34, and the worktable 41, the spindle box 34 is moved directly above the worktable 41. The spindle box 34 is then slowly lowered so that the protective frame 5 presses against the worktable 41. Finally, the movement of the worktable 41 is restricted by the stop seat 74, allowing the worktable 41 to support the weight of the spindle box 34. The protective frame 5 is then fixed to the worktable 41 to prevent it from detaching. This ensures that the spindle box 34 does not move on its own during transportation and avoids strong vibrations or collisions that could damage the tool spindle 35.

[0031] Similarly, to prevent the Z-axis slide 24 from moving on its own during transportation and to prevent damage to the laser assembly 25, before shipment, the fixed bracket 6 is first installed on the bed 1. Then, by moving the first Y-axis slide 22 and the Z-axis slide 24, the Z-axis slide 24 is moved directly above the fixed bracket 6. The Z-axis slide 24 is then slowly lowered so that it presses against the crossbeam 611 of the fixed bracket 6, and the fixed bracket 6 supports the weight of the Z-axis slide 24. The bottom of the Z-axis slide 24 is screwed to the fixed bracket 6, so that the Z-axis slide 24 and the fixed bracket 6 cannot be separated. This ensures that the Z-axis slide 24 is safely and reliably supported and that it does not move on its own during transportation, thus preventing strong vibrations or collisions that could damage the laser assembly 25.

[0032] This invention solves the problem of transporting and securing sliding components on a composite machining center. A protective frame 5 cleverly secures the spindle box 34 and the tool spindle 35 to the worktable 41. The worktable 41 supports and secures the spindle box 34 and the tool spindle 35, while the protective frame 5 provides external protection for the tool spindle 35. Furthermore, a fixed bracket 6 is installed on the bed 1 to support and secure the Z-axis slide saddle 24 and the laser assembly 25, ensuring that the tool spindle 35 and the laser assembly 25 do not move during transport and thus avoid collision damage. Once the composite machining center arrives at its destination, the protective frame 5, the fixed bracket 6, and the stop seat can be quickly disconnected without affecting subsequent debugging and installation of the machine tool.

[0033] For details, please refer to Figure 5 and Figure 6 The fixed bracket 6 includes a gantry frame 61 composed of a crossbeam 611 and two vertical beams 612, and two pad beams 62 respectively set at the bottom of the corresponding vertical beams 612. The crossbeam 611 is connected to the bottom of the Z-axis slide saddle 24 by a first locking screw, and the pad beams 62 are fixed to the bed 1 by a second locking screw.

[0034] For material selection and processing, in this embodiment, the crossbeam 611, vertical beam 612, and pad beam 62 are all square tubes. The crossbeam 611, vertical beam 612, and pad beam 62 are assembled by welding. The outer surfaces of the crossbeam 611 and pad beam 62 are rough and uneven. It is difficult for the crossbeam 611 to form a stable and reliable joint surface with the bottom surface of the laser spindle box 34. Similarly, the pad beam 62 also forms a stable and reliable joint surface with the top surface of the bed 1.

[0035] Therefore, the top surface of the crossbeam 611 is provided with two or more first precision-reinforced flat blocks 63, each of which has a vertically extending first through hole 631. The crossbeam 611 has a first avoidance hole 6110 for the first locking screw to pass through from bottom to top and to engage with the first through hole 631. The bottom surface of the laser spindle box 34 presses against the first precision-reinforced flat block 63. The first locking screw is fitted with a washer, and then passes through the first avoidance hole 6110 and the first through hole 631 in sequence before being tightened into the first threaded hole to achieve fixation, resulting in a good connection effect.

[0036] Further, two or more second precision flat blocks 64 are provided on the bottom surface of the cushion beam 62. Each second precision flat block 64 is provided with a second through hole 641 extending vertically. The cushion beam 62 is provided with a second avoidance hole 621 for a second locking screw to pass through from top to bottom and for the second locking screw to cooperate with the second through hole 641. The machine tool bed 1 is provided with a second threaded hole for cooperating with the second locking screw. The second precision flat block 64 is pressed on the machine tool bed 1. A washer is sleeved on the second locking screw, and then the second locking screw passes through the second avoidance hole 621 and the second through hole 641 in sequence and is screwed tightly with the second threaded hole to achieve fixation.

[0037] To strengthen the structural strength of the gantry 61, the interior of the gantry 61 is fixedly connected by a "丄" - shaped frame 65. That is, the crossbar part of the "丄" - shaped frame 65 is connected to the two vertical beams 612, and the vertical bar part of the "丄" - shaped frame 65 is connected to the center of the bottom of the cross beam 611.

[0038] To strengthen the connection strength between the vertical beam 612 and the cushion beam 62 and avoid the inclined bending of the vertical beam 612 and the cushion beam 62 caused by excessive load, the corner formed by the vertical beam 612 and the cushion beam 62 is strengthened by a gusset plate 66.

[0039] Specifically, please refer to Figure 3 , the protective frame 5 includes a bottom plate 51, a back plate 52 vertically arranged on the bottom plate 51, and two side plates 53. In the top - view projection, the back plate 52 and the two side plates 53 enclose a "冂" - shaped cavity 57. Horizontal wing plates 54 are provided on the outer sides of the two side plates 53. Each wing plate 54 is provided with a first mounting hole 541. The bottom of the spindle box 34 is provided with a third threaded hole corresponding to the first mounting hole 541. A third locking screw passes through the first mounting hole 541 from bottom to top and is screwed tightly with the third threaded hole, thereby fixing the protective frame 5 on the spindle box 34. On the one hand, the protective frame 5 provides external protection for the output end of the tool spindle 35, and on the other hand, it serves as a fixing medium between the spindle box 34 and the workbench 41.

[0040] In fact, an operation window that connects the cavity 57 of the protective frame 5 to the outside is formed in front of the protective frame 5. The bottom plate 51 is provided with a plurality of second mounting holes 511. Correspondingly, a clamping plate 43 is provided on the top of the workbench 41. The clamping plate 43 is provided with a plurality of 丄 - shaped grooves 44 arranged in parallel and extending along the Y - axis. After the head of the locking bolt is caught in the 丄 - shaped groove 44, it then passes through the second mounting hole 511 and is tightened and fixed with a nut. The hand of the staff can reach into the operation window and enter the cavity 57 for operation.

[0041] In order to allow the worktable to slide smoothly, the machine tool is provided with an X-axis guide rail 45 extending along the X-axis. The X-axis guide rail 45 passes through the gantry of the first gantry 21 and the second gantry 31. The bottom of the worktable 41 is fixedly connected with an X-axis slider 46 for sliding connection with the X-axis guide rail 45.

[0042] To enhance the structural strength of the wing plate 54 and prevent it from deforming under pressure, an H-shaped frame 55 is connected to the lower part of the wing plate 54. The inner side of the H-shaped frame 55 is connected to the side plate 53, and the bottom of the H-shaped frame 55 is connected to the bottom plate 51. The H-shaped frame 55 provides stable support for the wing plate 54.

[0043] Preferably, the inner cavity 57 is provided with a reinforcing back plate 52 and an inner strip 56 connected to the two side plates 53.

[0044] Preferably, the side panel 53 is a right-angled trapezoid. This design eliminates the front corners of the side panel 53, preventing them from obstructing operator work.

[0045] See Figure 1 and Figure 4 As shown, it should be noted that, due to the large weight of the first Y-axis slide 22 and Z-axis slide 24, if the composite machining tool tilts or vibrates during transportation, the first Y-axis slide 22 and Z-axis slide 24 will generate a large amount of kinetic energy, which can easily cause the Z-axis slide 24 transportation fixing structure to fail. Therefore, in order to better ensure the stability of the Z-axis slide 24 transportation fixing structure, the Z-axis slide 24 and the first Y-axis slide 22 are fixedly connected by the first locking block and the fourth locking screw, and the first Y-axis slide 22 is fixedly connected to the first gantry 21 by the first locking seat 71 and the fifth locking screw. Similarly, since the second Y-axis slide 32 and the spindle box 34 are relatively heavy, if the composite machining tool tilts or vibrates during transportation, the second Y-axis slide 32 and the spindle box 34 will generate a large amount of kinetic energy, which may easily cause the aforementioned spindle box 34 transportation fixing structure to fail. Therefore, in order to better ensure the stability of the spindle box 34 transportation fixing structure, the spindle box 34 and the second Y-axis slide 32 are fixedly connected by the second locking block 72 and the sixth locking screw, and the second Y-axis slide 32 is fixedly connected to the second gantry 31 by the second locking seat 73 and the seventh locking screw.

[0046] To meet diverse machining requirements and eliminate the inconvenience of manual tool changing, a tool magazine is typically installed on the side of the machine bed 1. The tool magazine works in conjunction with the clamping spindle to achieve automatic tool changing. The tool spindle 35 is used to clamp the tool, which is used to cut the workpiece on the worktable 41. The tool spindle 35 needs to rotate at high speed when machining the workpiece, and the tool will generate heat. At the same time, the waste chips generated during cutting will also accumulate on the tool. Therefore, air is blown away from the tool or sprayed with lubricant, coolant, etc. through accessories such as nozzles and hoses. Currently, nozzles are generally set at the bottom of the spindle box 34. The nozzles are connected to hoses. That is, the hose needs to go around the bottom of the spindle box 34 before connecting to the nozzles located at the bottom of the spindle box 34. If the hose is not fixed properly and becomes too long, it may touch the workpiece, affecting the movement of the tool spindle 35. Moreover, the hose is also prone to damage due to scratching.

[0047] Please see Figure 7 A connector 81 is provided on the side wall of the spindle box 34, and a nozzle 82 is provided at the bottom of the spindle box 34. A flow guide channel is provided at the bottom of the spindle box 34. The connector 81 and the nozzle 82 are connected through the flow guide channel. The free end of the connector 81 is used to connect to a hose. The end of the nozzle 82 is inclined toward the tool spindle 35.

[0048] In practical use, the free end of connector 81 is connected to one end of the hose, and the other end of the hose is connected to the gas storage mechanism, lubricant storage mechanism, or coolant storage mechanism. The pump body's pressurization allows gas, lubricant, or coolant to be supplied to the hose. This gas, lubricant, or coolant then passes through the hose and connector, enters the connecting channel, and is subsequently ejected through the nozzle. When gas is ejected, it blows gas onto the tool mounted on the tool spindle 35, removing debris. When lubricant is ejected, it lubricates the tool surface, reducing friction during workpiece machining. When coolant is ejected, it cools the tool. This arrangement allows the hose to be positioned above the bottom of the tool spindle 35, eliminating the need to pass around the bottom of the spindle housing 34 and preventing the hose from contacting the workpiece.

[0049] In this embodiment, since linear motors can achieve direct transmission and have advantages such as lightweight structure, high transmission efficiency, safety and reliability, and long service life, the X-axis drive mechanism 42, the first Y-axis drive mechanism 23, and the second Y-axis drive mechanism 33 all use linear motors. The stator of the linear motor is fixed, and the mover of the linear motor drives the corresponding components to move. The first Z-axis drive mechanism 26 and the second Z-axis drive mechanism 36 use a motor-driven lead screw motion. The first gantry 21 is provided with a first Y-axis guide rail extending left and right, and the first Y-axis slide saddle 22 is slidably connected to the first Y-axis guide rail through a first Y-axis slider; the back of the Z-axis slide saddle 24 is provided with a first Z-axis guide rail extending vertically, and the first Y-axis slide saddle 22 is provided with a first Z-axis slider. The Z-axis slide saddle 24 is slidably connected to the first Z-axis guide rail through the first Z-axis slider, so the Z-axis slide saddle 24 and the first Y-axis slide saddle 22 slide smoothly. The second gantry 31 is provided with a second Y-axis guide rail extending to the left and right. The second Y-axis slide saddle 32 is slidably connected to the second Y-axis guide rail through the second Y-axis slider. The back of the spindle box 34 is provided with a second Z-axis guide rail extending vertically. The second Y-axis slide saddle 32 is provided with a first Z-axis slider. The spindle box 34 is slidably connected to the second Z-axis guide rail through the second Z-axis slider. Therefore, the spindle box 34 and the second Y-axis slide saddle 32 slide smoothly.

[0050] Specifically, the laser assembly 25 includes a bracket fixed on the Z-axis slide saddle 24, and a laser rotary cutting module or a galvanometer scanning cutting module mounted on the bracket. The laser rotary cutting module or the galvanometer scanning cutting module emits a laser to perform laser processing on the workpiece.
