Description

Technical Field

[0001] The invention relates to the field of numerically controlled machine tools, and in particular to a composite machining machine tool. Background Art

[0002] With the rapid development of modern industry, the types, shapes, precision and efficiency requirements of processed materials are constantly improving, which puts forward higher requirements for processing machine tools. The processing of materials often requires multiple processes. The special nature of traditional machine tools requires each process to be completed on multiple machine tools. Multiple clamping affects the processing quality and precision, and it is difficult to ensure processing efficiency. Therefore, composite processing machine tools that integrate laser processing and tool processing are continuously developed.

[0003] The composite processing machine tool includes a laser processing mechanism, a tool processing mechanism, a worktable that can slide along the X-axis, and an X-axis driving mechanism that drives the worktable to move. Taking the tool processing mechanism as an example, the tool processing mechanism mainly includes a gantry fixed on the bed, a Y-axis saddle that can be slidably set on the gantry, a Y-axis driving mechanism for driving the Y-axis saddle, a spindle box that can be slidably set on the Y-axis saddle, a Z-axis driving mechanism that drives the spindle box to move along the Z-axis, and a tool spindle set on the spindle box. In fact, the CNC machine tool is only partially assembled before the factory is shipped. The X-axis driving mechanism, the Y-axis driving mechanism, and the Z-axis driving mechanism are not connected to the corresponding components. Therefore, the laser processing mechanism, the tool processing mechanism, and the worktable will shake violently during transportation, and may even collide with the bed to cause damage. It is difficult to ensure the working performance of the tool spindle and the laser assembly after arriving at the destination. Therefore, in order to protect the tool spindle and the laser assembly, it is urgent to fix the laser processing mechanism, the tool processing mechanism, and the worktable before the laser processing machine tool is transported.

Detailed implementation mode

[0026] The present invention provides a compound machine tool. To make the purpose, technical solution and effect of the present invention clearer and more definite, the following further elaborates on the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0027] Please refer to Figure 1 and Figure 2 The present invention provides a composite machining machine tool, comprising a bed 1, a first gantry 21 and a second gantry 31 arranged on the bed 1 front and back, a workbench 41 slidably arranged on the bed 1 front and back, an X-axis driving mechanism 42 for driving the workbench 41 to move forward and backward, and the first gantry 21 and the second gantry 31 fixedly arranged on the bed 1 and passing through the moving route of the workbench 41; a first Y-axis saddle 22 and a first Y-axis driving mechanism 23 for driving the first Y-axis saddle 22 to move left and right are slidably arranged on the first gantry 21, a Z-axis saddle 24 and a first Z-axis driving mechanism 26 for driving the Z-axis saddle 24 to move up and down are slidably arranged on the first Y-axis saddle 22, and a laser assembly 25 is arranged on the Z-axis saddle 24, and a laser assembly 25 is arranged on the second gantry 31. A second Y-axis saddle 32 and a second Y-axis driving mechanism 33 for driving the second Y-axis saddle 32 to move left and right are provided, a spindle box 34 and a second Z-axis driving mechanism 36 for driving the spindle box 34 to move up and down are slidably provided on the second Y-axis saddle 32, 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 for surrounding the output end of the spindle box 34 is installed at the bottom of the spindle box 34, the protective frame 5 is clamped on the workbench 41, a stop seat 74 for limiting the sliding of the workbench 41 is installed on the bed 1, a fixed bracket 6 is installed on the bed 1, and the bottom of the Z-axis saddle 24 is connected to the fixed bracket 6.

[0028] The composite machining machine provided by the present invention adopts a double gantry structure layout, so that double machining stations are formed 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 by clamping once, thereby reducing the clamping error caused by disassembling the workpiece and improving the machining accuracy and efficiency.

[0029] When the composite machining machine tool is shipped, the composite machining machine tool has completed the sliding assembly of the first Y-axis saddle 22 and the Z-axis saddle 24, and the sliding assembly of the second Y-axis saddle 32 and the spindle box 34. Since 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 need to be transported to the destination before transmission debugging, and no driving connection is formed with the corresponding components, the first Y-axis saddle 22 and the second Y-axis saddle 32 can move freely along the Y-axis, and the Z-axis saddle 24 and the spindle box 34 can move automatically along the Z-axis. The spindle box 34 is provided with a tool spindle 35 and the output end of the tool spindle 35 extends from the bottom of the spindle box 34. In order to limit the self-motion of the spindle box 34 during transportation and prevent the tool spindle 35 from being damaged, the protective frame 5 is first installed on the bottom of the spindle box 34 before shipment, so that the protective frame 5 can provide external protection for the output end of the tool spindle 35. Then, the spindle box 34 is moved to the top of the workbench 41 by moving the second Y-axis saddle 32, the spindle box 34 and the workbench 41. The spindle box 34 is slowly lowered so that the protective frame 5 is pressed against the workbench 41. Finally, the movement of the workbench 41 is limited by the stop seat 74, and the weight of the spindle box 34 is supported by the workbench 41. Then, the protective frame 5 is fixed on the workbench 41 so that the protective frame 5 cannot be separated from the workbench 41, thereby ensuring that the spindle box 34 cannot self-move during transportation and avoiding strong vibration or collision of the spindle box 34 and damage to the tool spindle 35.

[0030] Similarly, in order to limit the self-motion of the Z-axis saddle 24 during transportation and prevent the laser assembly 25 from being damaged, before shipment, the fixed bracket 6 is first installed on the bed 1, and then the Z-axis saddle 24 is moved to the top of the fixed bracket 6 by moving the first Y-axis saddle 22 and the Z-axis saddle 24, and the Z-axis saddle 24 is slowly lowered so that the Z-axis saddle 24 is pressed against the crossbeam 611 of the fixed bracket 6, and the fixed bracket 6 supports the weight of the Z-axis saddle 24; the bottom of the Z-axis saddle 24 is screwed to the fixed bracket 6, so that the Z-axis saddle 24 and the fixed bracket 6 cannot be separated, and the Z-axis saddle 24 is safely and reliably supported to ensure that the Z-axis saddle 24 cannot self-move during transportation, and to avoid strong vibration or collision of the Z-axis saddle 24 and damage to the laser assembly 25.

[0031] The present invention solves the problem of transporting and fixing sliding parts on a composite machining machine. The main spindle box 34 and the tool spindle 35 are cleverly fixed on the workbench 41 through the protective frame 5. The main spindle box 34 and the tool spindle 35 are supported and fixed by the workbench 41, and the protective frame 5 also provides external protection for the tool spindle 35. In addition, by arranging a fixed bracket 6 on the bed 1 to support and fix the Z-axis saddle 24 and the laser assembly 25, it is ensured that the tool spindle 35 and the laser assembly 25 cannot move by themselves during transportation to avoid collision damage. When the composite machining machine is transported to the destination, the connection between the protective frame 5, the fixed bracket 6, and the stop seat can be quickly released without affecting the subsequent debugging and installation of the composite machining machine.

[0032] For details, please refer to Figure 5 and Figure 6 The fixed bracket 6 includes a gantry frame body 61 composed of a horizontal beam 611 and two vertical beams 612, and two cushion beams 62 respectively arranged at the bottom of the corresponding vertical beams 612. The horizontal beam 611 is connected to the bottom of the Z-axis saddle 24 through a first locking screw, and the cushion beam 62 is fixed to the bed 1 through a second locking screw.

[0033] For material selection and processing, in the present embodiment, the cross beam 611, the vertical beam 612 and the cushion beam 62 are all square tubes, and the cross beam 611, the vertical beam 612 and the cushion beam 62 are assembled by welding. The outer surfaces of the cross beam 611 and the cushion beam 62 are rough and uneven, and it is difficult for the cross beam 611 and the bottom surface of the laser spindle box 34 to form a smooth and reliable bonding surface. Similarly, the cushion beam 62 and the top surface of the bed 1 also form a smooth and reliable bonding surface.

[0034] Therefore, the top surface of the crossbeam 611 is provided with more than two first fine flat blocks 63, each of which is provided with a first through hole 631 extending vertically, and the crossbeam 611 is provided with a first avoidance hole 6110 for the first locking screw to pass through from bottom to top and to make the first locking screw match the first through hole 631. The bottom surface of the laser spindle box 34 is pressed against the first fine flat block 63, the first locking screw is covered with a washer, and then passes through the first avoidance hole 6110 and the first through hole 631 in turn, and is tightened and matched with the first threaded hole to achieve fixation, and the connection effect is good.

[0035] Further, more than two 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. A second avoiding hole 621 is provided on the cushion beam 62 for the second locking screw to pass through from top to bottom and for the second locking screw to cooperate with the second through hole 641. A second threaded hole for cooperating with the second locking screw is provided on the machine tool bed body 1. The second precision flat block 64 is pressed on the machine tool bed body 1. A washer is sleeved on the second locking screw, and then the second locking screw passes through the second avoiding hole 621 and the second through hole 641 in sequence and is screwed tightly with the second threaded hole to achieve fixation.

[0036] To strengthen the structural strength of the gantry body 61, the inside of the gantry body 61 is fixedly connected through an "丄"-shaped frame 65, that is, the cross bar 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.

[0037] 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 and connected through an angle plate 66.

[0038] 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 shape to form an inner 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. A third threaded hole corresponding to the first mounting hole 541 is provided at the bottom of the spindle box 34. The 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.

[0039] In fact, an operation window for communicating the inner cavity 57 of the protective frame 5 with the outside is formed in front of the protective frame 5. A plurality of second mounting holes 511 are provided on the bottom plate 51. Correspondingly, a clamping plate 43 is provided on the top of the workbench 41. A plurality of 丄-shaped grooves 44 arranged in parallel and extending along the Y axis are provided on the clamping plate 43; after the head of the locking bolt is stuck into 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 worker can reach into the operation window and enter the inner cavity 57 for operation.

[0040] In order to ensure smooth sliding of the workbench, 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 gates of the first gantry 21 and the second gantry 31. The bottom of the workbench 41 is fixedly connected with an X-axis slider 46 for sliding connection with the X-axis guide rail 45.

[0041] In order to strengthen the structural strength of the wing plate 54 to prevent the wing plate 54 from being deformed by pressure, an H-shaped frame 55 is connected to the bottom 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, so that the H-shaped frame 55 provides stable support for the wing plate 54.

[0042] Preferably, an inner strip 56 connecting the reinforcing back plate 52 and the two side plates 53 is provided in the inner cavity 57 .

[0043] Preferably, the side plate 53 is in a right-angle trapezoidal shape. By arranging in this way, the front corners of the side plate 53 can be eliminated to prevent the corners from hindering the operation of the staff.

[0044] See Figure 1 and Figure 4 As shown, it should be noted that due to the large weight of the first Y-axis saddle 22 and the Z-axis saddle 24, once the composite machining center tilts or vibrates during transportation, the first Y-axis saddle 22 and the Z-axis saddle 24 will generate a large kinetic energy, which may easily cause the above-mentioned Z-axis saddle 24 transportation fixing structure to fail. Therefore, in order to better ensure the stability of the Z-axis saddle 24 transportation fixing structure, the Z-axis saddle 24 is fixedly connected to the first Y-axis saddle 22 by a first locking block and a fourth locking screw, and the first Y-axis saddle 22 is fixedly connected to the first gantry 21 by a first locking seat 71 and a fifth locking screw. Similarly, due to the large weight of the second Y-axis saddle 32 and the spindle box 34, once the composite machining center tilts or vibrates during transportation, the second Y-axis saddle 32 and the spindle box 34 will generate a large kinetic energy, which may easily cause the above-mentioned spindle box 34 transportation and fixing structure to fail. Therefore, in order to better ensure the stability of the spindle box 34 transportation and fixing structure, the spindle box 34 and the second Y-axis saddle 32 are fixedly connected by a second locking block 72 and a sixth locking screw, and the second Y-axis saddle 32 is fixedly connected to the second gantry 31 by a second locking seat 73 and a seventh locking screw.

[0045] In order to meet the diverse processing requirements and eliminate the inconvenience of manual tool change, a tool magazine is usually arranged on the side of the bed 1, and the tool magazine cooperates with the clamping spindle to realize automatic tool change. The tool spindle 35 is used to clamp the tool, and the tool is used to cut the workpiece on the workbench 41. The tool spindle 35 needs to rotate at high speed when processing the workpiece, and the tool will heat up. At the same time, the waste chips generated when cutting the workpiece will also be deposited on the tool. Therefore, the tool will be sprayed with air through accessories such as nozzles and hoses to blow away the waste chips or spray lubricants, coolants, etc. At present, a nozzle is generally set at the bottom of the spindle box 34, and the nozzle is connected to the hose, that is, the hose needs to go around the bottom of the spindle box 34 and then connect to the nozzle located at the bottom of the spindle box 34. When the hose is improperly fixed and becomes longer, it may touch the workpiece, affecting the movement of the tool spindle 35, and the hose is also easily damaged by scratching.

[0046] See also Figure 7 A joint 81 is provided on the side wall of the spindle box 34, a nozzle 82 is provided at the bottom of the spindle box 34, a guide channel is opened at the bottom of the spindle box 34, the joint 81 and the nozzle 82 are connected through the guide channel, the free end of the joint 81 is used to be connected to a hose, and the end of the nozzle 82 is inclined toward the direction of the tool spindle 35.

[0047] In actual use, the free end of the connector 81 is connected to one end of the hose, and the other end of the hose is connected to the gas storage mechanism or the lubricant storage mechanism or the coolant storage mechanism. The pressurization effect of the pump body can be used to provide gas or lubricant or coolant to the hose, so that the gas or lubricant or coolant passes through the hose and the connector and enters the connecting channel and then is sprayed out through the nozzle. When the sprayed gas is gas, the tool clamped on the tool spindle 35 can be sprayed with gas to blow away the waste chips; when the sprayed lubricant is lubricant, the surface of the tool can be lubricated to reduce the friction during workpiece processing; when the sprayed coolant is coolant, the tool can be cooled. The above arrangement allows the hose to be located above the bottom of the tool spindle 35, that is, it does not need to go around the bottom of the spindle box 34 when in use, and the hose can be prevented from touching the workpiece.

[0048] In this embodiment, since the linear motor can realize direct transmission, it has the advantages of light structure, high transmission efficiency, safety and reliability, and long service life, so 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 stators of the linear motors are fixed, and the movers of the linear motors drive the corresponding components to move. The first Z-axis drive mechanism 26 and the second Z-axis drive mechanism 36 use the method of motor-driven lead screw movement. The first gantry 21 is provided with a first Y-axis guide rail extending left and right, and the first Y-axis saddle 22 is slidably connected to the first Y-axis guide rail through the first Y-axis slider; the back of the Z-axis saddle 24 is provided with a first Z-axis guide rail extending vertically, and the first Y-axis saddle 22 is provided with a first Z-axis slider, and the Z-axis saddle 24 is slidably connected to the first Z-axis guide rail through the first Z-axis slider, so the Z-axis saddle 24 and the first Y-axis saddle 22 slide smoothly. The second gantry 31 is provided with a second Y-axis guide rail extending left and right, and the second Y-axis saddle 32 is slidably connected to the second Y-axis guide rail through a second Y-axis slider; the back of the spindle box 34 is provided with a second Z-axis guide rail extending vertically, and the second Y-axis saddle 32 is provided with a first Z-axis slider, and the spindle box 34 is slidably connected to the second Z-axis guide rail through the second Z-axis slider, so the spindle box 34 and the second Y-axis saddle 32 slide smoothly.

[0049] Specifically, the laser assembly 25 includes a bracket fixed on the Z-axis saddle 24 and a laser peeling module / galvanometer scanning cutting module arranged on the bracket. The laser peeling module / galvanometer scanning cutting module emits laser to perform laser processing on the workpiece.
