[0002] In the prior art, the spindle of a horizontal drilling machine is usually arranged horizontally, and during the machining process, the cutting force mainly acts in the horizontal direction. The spindle of a vertical drilling machine is usually arranged vertically, and during the machining process, the cutting force mainly acts in the vertical direction. Most technical machining centers are independent horizontal machining centers or vertical machining centers. When a single machining center processes a workpiece, it is necessary to clamp the workpiece multiple times, which seriously affects the machining efficiency and machining accuracy.

[0003] In addition, the gun drill tools used in horizontal drilling machines have a large aspect ratio, which results in insufficient rigidity of the gun drill tools.

[0052] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0053] The embodiment of the present application provides a composite drilling machine tool, which can be used for deep hole processing of a workpiece. The composite drilling machine tool of the embodiment of the present application supports the gun drill clamped by the horizontal spindle through a support assembly to enhance the rigidity of the horizontal gun drill, effectively reducing the vibration of the horizontal gun drill during processing and improving the processing accuracy.

[0054] Please also read Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the composite drilling machine tool 100 provided in an embodiment of the present application. Figure 2 for Figure 1 The diagram shown is an enlarged schematic diagram of a portion of the structure of the composite drilling machine tool 100.

[0055] The compound drilling machine 100 includes a machine base 11. The main function of the machine base 11 is to support the weight of the entire compound drilling machine 100. Therefore, the machine base 11 can be designed to be thicker or larger in size to enhance the stability of the compound drilling machine 100 and reduce the vibration generated when the compound drilling machine 100 is working, thereby ensuring processing accuracy.

[0056] The compound drilling machine tool 100 further includes a driving assembly 20, a vertical spindle box 32 and a horizontal spindle box 31. The driving assembly 20 is disposed on the machine base 11, and the driving assembly 20 is used to carry a workpiece and can drive the workpiece to move.

[0057] The vertical spindle box 32 is disposed on the machine base 11 and includes a vertical spindle 321 for processing a workpiece in a vertical direction. The vertical spindle 321 can move in a vertical direction, for example, in a Z direction as shown in the figure, to adjust the height of the vertical spindle 321 .

[0058] The horizontal spindle box 31 is arranged on the machine base 11, and the horizontal spindle box 31 is spaced apart from the vertical spindle box 32. The horizontal spindle box 31 includes a horizontal spindle 311, and the horizontal spindle 311 is used to clamp a horizontal gun drill or a horizontal non-gun drill tool. The horizontal gun drill is used to perform deep hole drilling processing on the workpiece in the first horizontal direction (for example, the X direction shown in the figure), and the horizontal non-gun drill tool is used to perform processing other than deep hole drilling on the workpiece in the first horizontal direction (for example, the X direction shown in the figure).

[0059] The horizontal spindle box 31 is spaced apart from the vertical spindle box 32. The horizontal spindle box 31 can move along the first horizontal direction, thereby driving the horizontal spindle 311 to move along the first horizontal direction, for example, along the X direction shown in the figure. The horizontal spindle box 31 can be understood as the X axis of the compound drilling machine 100.

[0060] The composite drilling machine 100 of the present application integrates a vertical spindle box 32 and a horizontal spindle box 31, and can complete processing in the vertical direction and the first horizontal direction in one clamping of the workpiece, thereby reducing the number of workpiece clamping times to improve processing efficiency.

[0061] The compound drilling machine tool 100 also includes a support assembly 40, which is arranged on the machine base 11, and the support assembly 40 can move between a support position and an avoidance position; when the horizontal spindle 311 clamps a horizontal gun drill, the support assembly 40 moves to the support position to support the horizontal gun drill; when the horizontal spindle 311 clamps a horizontal non-gun drill tool, the support assembly 40 moves to the avoidance position to avoid the non-gun drill tool.

[0062] When the support assembly 40 supports the horizontal gun drill clamped on the horizontal spindle 311, the position of the support assembly 40 is the support position. When the support assembly 40 does not interfere with the horizontal non-gun drill tool clamped on the horizontal spindle 311, the position of the support assembly 40 is the avoidance position.

[0063] When the horizontal spindle 311 clamps a horizontal non-gun drilling tool (such as a horizontal milling cutter), the support assembly 40 moves to the avoidance position to avoid the horizontal non-gun drilling tool, thereby preventing the support assembly 40 from interfering with the work of the horizontal non-gun drilling tool. It is understandable that when the horizontal spindle 311 replaces the clamped tool, the support assembly 40 can also move to the avoidance position to avoid damage to the support assembly 40 during the tool replacement process.

[0064] It should be noted that during horizontal drilling, since the horizontal gun drill used has a relatively large aspect ratio, resulting in insufficient rigidity of the horizontal gun drill, the support assembly 40 can be used to support the horizontal gun drill to enhance the rigidity of the horizontal gun drill and prevent the horizontal gun drill from severe shaking during the processing, so as to improve the accuracy of deep hole drilling.

[0065] Therefore, when the horizontal spindle 311 clamps the horizontal gun drill, the support assembly 40 of the composite drilling machine 100 of the present application can provide additional support for the horizontal gun drill, effectively reducing the vibration of the horizontal gun drill during the processing, thereby improving the processing accuracy.

[0066] In addition, when the horizontal spindle 311 clamps different tools, the support assembly 40 can move between the support position and the avoidance position to adapt to different processing requirements. A variety of processing operations can be completed without replacing the compound drilling machine 100 or performing complex setting adjustments, thereby improving the flexibility and versatility of the compound drilling machine 100.

[0067] The drive assembly 20 drives the workpiece to move so that the vertical spindle 321 and the horizontal spindle 311 can perform machining operations such as drilling at different positions or angles on the workpiece. For example, the drive assembly 20 can drive the workpiece to move in a horizontal direction; the drive assembly 20 can drive the workpiece to move in a vertical direction; the drive assembly 20 can also drive the workpiece to rotate, etc.

[0068] The composite drilling machine 100 further includes a horizontal beam 51, which is disposed on the machine base 11 and connected to the horizontal spindle box 31 and the support assembly 40. The horizontal spindle box 31 can move along a first horizontal direction on the horizontal beam 51, for example, along the X direction shown in the figure. The horizontal beam 51 is used to drive the horizontal spindle box 31 and the support assembly 40 to move along a vertical direction, for example, along the Z direction shown in the figure.

[0069] Among them, the horizontal beam 51 is extended along the first direction, and the horizontal spindle box 31 is slidably connected to the horizontal beam 51. For example, the horizontal spindle box 31 can be slidably connected to the horizontal beam 51 through a guide rail, so that the horizontal spindle box 31 can move in the first horizontal direction to facilitate horizontal processing of the workpiece.

[0070] In addition, the horizontal beam 51 is slidably connected to the machine base 11, for example, the horizontal beam 51 can be slidably connected to the machine base 11 through a guide rail, so that the horizontal spindle box 31 can be driven to move in the vertical direction to adjust the height of the tool clamped by the horizontal spindle 311. The horizontal beam 51 can also drive the support assembly 40 to move in the vertical direction to adjust the height of the support assembly 40, so as to realize the automatic switching of the support assembly 40 between the avoidance position and the support position. It can be understood that the compound drilling machine 100 is also provided with a servo motor, which can be installed on the machine base 11 or on the horizontal beam 51. The servo motor can drive the horizontal beam 51 to move in the vertical direction, so that the horizontal beam 51 drives the horizontal spindle box 31 and the support assembly 40 to move in the vertical direction.

[0071] Therefore, when the composite drilling machine 100 of the present application performs horizontal processing, the support assembly 40 is driven to move by the horizontal crossbeam 51 to provide support or avoidance in the corresponding state. There is no need to frequently disassemble or remove the support assembly 40 manually. This is not only easy to operate, but also avoids the problems of time waste and position adjustment errors that may be caused by manual operation, thereby improving processing efficiency and processing accuracy.

[0072] In addition, the composite drilling machine 100 further includes a crossbeam 12 and a column 13. The crossbeam 12 is connected to the machine base 11, and the crossbeam 12 is arranged on one side of the machine base 11. The machine base 11 can be placed horizontally, and the crossbeam 12 is extended in the horizontal direction. The column 13 is connected to the machine base 11, and the column 13 can be arranged on one side of the machine base 11. The machine base 11 is placed horizontally, and the column 13 extends vertically upward.

[0073] The crossbeam 12 is used to provide a stable platform for installing some components of the compound drilling machine 100, such as the horizontal spindle box 31 or other processing heads. The column 13 is used to install some components of the compound drilling machine 100, such as the vertical spindle box 32 or other processing heads. The machine base 11, the crossbeam 12 and the column 13 together constitute the main frame of the compound drilling machine 100, which supports and fixes other structures on the compound drilling machine 100.

[0074] In some embodiments, the vertical spindle box 32 is slidably connected to the column 13, for example, the vertical spindle box 32 can be slidably connected to the column 13 through a guide rail. The vertical spindle 321 is fixedly connected to the vertical spindle box 32. The vertical spindle box 32 is used to drive the vertical spindle 321 to move in the vertical direction, for example, it can move in the Z direction shown in the figure, so as to adjust the height of the vertical spindle 321.

[0075] In some embodiments, the driving assembly 20 includes a first sliding mechanism 21 , a second sliding mechanism 22 , and a rotating mechanism 23 .

[0076] The first sliding mechanism 21 is arranged on the machine base 11, and the first sliding mechanism 21 can slide along the second horizontal direction, for example, can slide along the Y direction shown in the figure. For example, in actual application, the first sliding mechanism 21 can be slidably connected with the machine base 11 through a guide rail, and the first sliding mechanism 23 is driven by an electric screw to slide along the Y direction. In this way, the workpiece 61 can be driven to move and accurately position along the Y direction. The first sliding mechanism 23 can be understood as the Y axis of the compound drilling machine 100. The first sliding mechanism 21 can be understood as the Y axis of the compound drilling machine 100.

[0077] The second sliding mechanism 22 is disposed on the first sliding mechanism 21, and the second sliding mechanism 22 can slide along the first horizontal direction, for example, along the X direction shown in the figure. For example, in actual application, the second sliding mechanism 22 can be slidably connected to the first sliding mechanism 21 through a guide rail, and the second sliding mechanism 22 can be driven by an electric screw to slide along the X direction. Thus, the second sliding mechanism 22 can realize the movement and accurate positioning of the workpiece along the X direction.

[0078] The rotating mechanism 23 is disposed on the second sliding mechanism 22, and is used to carry the workpiece. The rotating mechanism 23 has a surface for carrying the workpiece. The second rotating mechanism 23 can rotate around its own axis to drive the workpiece to rotate, wherein the axis passes through the center of the surface carrying the workpiece and is perpendicular to the surface. The rotating mechanism 23 can be understood as the C-axis of the compound drilling machine 100.

[0079] Therefore, the composite drilling machine 100 of the present application can directly perform horizontal inclined hole drilling on the workpiece, and during the process of drilling inclined holes, there is no need to transfer the workpiece between multiple machines and reposition and calibrate the workpiece. By clamping the workpiece once, straight holes and inclined holes can be processed on four surfaces of the workpiece on one machine tool, which can improve processing efficiency.

[0080] It can be understood that in the composite drilling machine 100 of the present application, when horizontal processing and vertical processing are realized, the driving assembly 20 is reused, that is, the surface of the rotating mechanism 23 is used to carry the workpiece, and the first sliding mechanism 21 can drive the workpiece to move along the second horizontal direction, the second sliding mechanism 22 drives the workpiece to move along the first horizontal direction, and the rotating mechanism 23 drives the workpiece to rotate. Then, the tool on the horizontal spindle 311 and the tool on the vertical spindle 321 are controlled to move respectively to realize horizontal processing and vertical processing of the workpiece.

[0081] The composite drilling machine 100 of the present application is used for horizontal deep hole drilling. The first sliding mechanism 21, the second sliding mechanism 22 and the rotating mechanism 23 drive the movement of the workpiece, and the horizontal gun drill on the horizontal spindle 311 moves in the vertical direction and the first horizontal direction. The horizontal gun drill can perform horizontal deep hole drilling on the workpiece at any spatial angle, for example, drilling inclined holes, that is, hole drilling can also be performed when the surface of the workpiece is not parallel to the horizontal plane.

[0082] Therefore, the composite drilling machine 100 of the present application can directly perform horizontal drilling of inclined holes on the workpiece, and during the process of drilling inclined holes, there is no need to transfer the workpiece between multiple machines and reposition and calibrate the workpiece. By clamping the workpiece once, straight holes and inclined holes can be drilled on four surfaces of the workpiece on one machine tool, which can improve processing efficiency.

[0083] See also Figure 1 and Figure 3 , Figure 3 for Figure 1 The structure diagram of the horizontal spindle 311 of the compound drilling machine 100 is shown. In some embodiments, the horizontal spindle 311 includes a nose 3111, the length of the nose 3111 ranges from 100 mm to 500 mm, and the nose 3111 is used to clamp a horizontal gun drill or a horizontal non-gun drill tool to process a workpiece on a surface.

[0084] In the related art, since the length of non-gun drill tools such as horizontal milling cutters is shorter than that of horizontal gun drills, when the tool clamped by the horizontal spindle is a horizontal non-gun drill tool (such as a milling cutter), a specially made extended milling cutter is required in order to allow the horizontal milling cutter to process the workpiece. The milling cutter itself is a consumable and needs to be replaced regularly due to wear during the processing. The specially made extended milling cutter is often more expensive due to its special specifications and manufacturing process.

[0085] In the present application, by lengthening the nose end 3111 of the horizontal spindle 311, a horizontal non-gun drill tool of ordinary specifications can be used to complete the processing task, avoiding the use of high-cost specially made extended horizontal non-gun drill tools, thereby achieving significant cost savings.

[0086] The rigidity of the extended nose end 3111 is higher than that of the extended milling cutter. During the machining process, the rigidity of the milling cutter has an important influence on machining accuracy and machining efficiency. When using an extended milling cutter with insufficient rigidity, the milling cutter may be deformed or vibrated under the action of the cutting force, which may lead to problems such as increased surface roughness of the machined workpiece or decreased dimensional accuracy. Therefore, since the nose end 3111 of the horizontal spindle 311 in the present application is extended so that the rigidity of the nose end 3111 is higher, it can better withstand the cutting force, reduce deformation and vibration during the machining process, thereby ensuring machining accuracy and machining quality.

[0087] The length of the nose tip 3111 may be 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm, 450 mm or 500 mm, etc., or the length of the nose tip 3111 may be any value within the numerical range defined by any two of the above numerical values. It is understood that if the length of the nose tip 3111 is less than 100 mm, the nose tip 3111 may be too short to touch the workpiece; if the length of the nose tip 3111 is greater than 500 mm, the rigidity of the nose tip 3111 may be reduced, thereby affecting the machining accuracy.

[0088] In some embodiments, the composite drilling machine 100 includes a first guide sleeve mechanism 70 and a guide sleeve magazine 90. The first guide sleeve mechanism 71 is slidably connected to the horizontal spindle box 31, and the first guide sleeve mechanism 71 is used to clamp the first guide sleeve 61. When the horizontal spindle 311 clamps the horizontal gun drill, the first guide sleeve 61 is used for the horizontal gun drill to pass through. The guide sleeve magazine 90 is arranged on the first sliding mechanism 21, and the guide sleeve magazine 90 is used to accommodate at least two first guide sleeves 61.

[0089] Among them, the first guide sleeve 61 can guide and position the horizontal gun drill, and can further prevent the horizontal gun drill from serious shaking during the processing, so as to further improve the accuracy of deep hole drilling. It can be understood that the horizontal gun drill has different specifications, such as different diameters, and the first guide sleeve 61 required to be adapted also needs to have different specifications. In practical applications, different horizontal gun drills can be selected according to processing requirements, and the first guide sleeve 61 adapted to the horizontal gun drill can be selected.

[0090] The first sliding mechanism 21 can drive the guide sleeve warehouse 90 to move along the second horizontal direction, for example, when sliding along the Y direction shown in the figure, the guide sleeve warehouse 90 can move to a position close to the first guide sleeve mechanism 71 to facilitate rapid removal and installation of the first guide sleeve 61 from the guide sleeve warehouse 90, thereby realizing automatic replacement of the first guide sleeve 61.

[0091] The first guide sleeve mechanism 71 is slidably connected to the horizontal spindle box 31, for example, the first guide sleeve mechanism 71 can be slidably connected to the horizontal spindle box 31 through a guide rail. The first guide sleeve mechanism 71 is fixedly connected to the first guide sleeve 61, and the first guide sleeve mechanism 71 is used to drive the first guide sleeve 61 to move along the first horizontal direction, for example, along the X direction shown in the figure, so as to adjust the position of the first guide sleeve 61 in the X direction shown in the figure.

[0092] In an example of practical application, the first guide sleeve mechanism 71 may be U-shaped as a whole. A larger through hole for clamping the first guide sleeve 61 may be provided at the bottom of the first guide sleeve mechanism 71. When the first guide sleeve mechanism 71 does not clamp the first guide sleeve 61, the nose end 3111 of the horizontal spindle 311 may pass through the through hole so that the horizontal tool clamped by the nose end 3111 can process the workpiece.

[0093] See also Figure 4 , Figure 4 for Figure 1 Another enlarged schematic diagram of a partial structure of the composite drilling machine 100 is shown. In some embodiments, the composite drilling machine 100 further includes a protective door 91, which is slidably disposed on the first sliding mechanism 21, and the protective door 91 can move between a first position and a second position to shield and expose the guide sleeve magazine 90.

[0094] When the protective door 91 moves to the first position, it can cover the guide sleeve magazine 90 to prevent chips or coolant splashes generated during the processing from entering the guide sleeve magazine 90. When the protective door 91 moves to the second position, the guide sleeve magazine 90 is exposed, which facilitates the automatic replacement of the first guide sleeve 61 and the operation and maintenance of the guide sleeve magazine 90 by the operator.

[0095] In practical applications, different first guide sleeves 61 can be manually selected from the guide sleeve library 90 and installed on the first guide sleeve mechanism 71. Alternatively, the compound drilling machine 100 can automatically select different first guide sleeves 61 from the guide sleeve library 90 according to processing requirements, and control the selected first guide sleeve 61 to be installed on the first guide sleeve mechanism 71.

[0096] For example, when replacing the first guide sleeve 61, the support assembly 40 is first controlled to move downward to the avoidance position, the horizontal spindle box 31 (i.e., the X-axis) is controlled to move right to the limit position, and the first guide sleeve mechanism 71 is moved left to the limit position to ensure that the tool has been detached from the horizontal spindle 311. The first sliding mechanism 21 is controlled to drive the guide sleeve magazine 90 to move backward to a position close to the first guide sleeve mechanism 71, the protective door 91 is controlled to move to the second position, and then the guide sleeve magazine 90 is rotated to the guide sleeve placement position, and then the horizontal spindle box 31 (i.e., the X-axis) is controlled to move left (the first guide sleeve mechanism 71 moves left at the same time) until the first guide sleeve slot and the clip of the guide sleeve magazine 90 have the same width, and then the guide sleeve magazine 90 is extended, and then the horizontal spindle box 31 is controlled to move right (the first guide sleeve mechanism 71 moves right at the same time) to make the first guide sleeve 61 detach from the first guide sleeve mechanism 71, and then the guide sleeve magazine 90 is retracted, and the disassembly of the original first guide sleeve 61 is completed. Subsequently, the tool of the horizontal spindle 311 is replaced. After the tool replacement is completed, the horizontal spindle box 31 (i.e., the X-axis) is similarly controlled to move right to the limit position, the first guide sleeve mechanism 71 is moved left to the limit position, and then the guide sleeve magazine 90 is rotated to the guide sleeve removal position, and then the horizontal spindle box 31 is controlled to move left to make the first guide sleeve 61 enter the first guide sleeve mechanism 71, and then the guide sleeve magazine 90 is controlled to retract to make the first guide sleeve 61 detach from the guide sleeve magazine 90, and the installation of the new first guide sleeve 61 is completed. In this way, the compound drilling machine 100 can automatically replace the first guide sleeve 61.

[0097] The first guide sleeve 61 may be disposed above the driving assembly 20, and the first guide sleeve 61 may move along a first horizontal direction, for example, along the X direction shown in the figure, to adjust the position of the first guide sleeve 61 in the first horizontal direction. When the horizontal spindle 311 clamps the horizontal gun drill, the first guide sleeve 61 is used for the horizontal gun drill to penetrate.

[0098] When the length of the horizontal gun drill clamped by the horizontal spindle 311 exceeds a certain length, the horizontal gun drill is supported by the support assembly 40 to enhance the rigidity of the horizontal gun drill, and the gun drill is guided and positioned by the first guide sleeve 61, which can further prevent the horizontal gun drill from severe shaking during the processing, so as to further improve the accuracy of deep hole drilling.

[0099] See also Figure 5 , Figure 5 for Figure 1 A schematic structural diagram of the first guide sleeve 61 of the compound drilling machine tool 100 is shown.

[0100] In some embodiments, the first guide sleeve 61 includes a clamping portion 611 and a guiding portion 612. The clamping portion 611 is used to be clamped by the first guide sleeve mechanism 71. The guiding portion 612 is used to guide the horizontal gun drill.

[0101] The clamping portion 611 is provided with an axial groove (not shown). The guide portion 612 is connected to the clamping portion 611, and the guide portion 612 is provided with a penetrating guide hole 612a, and the guide hole 612a is used for a horizontal gun drill to pass through, and the guide hole 612a is connected to the groove, and the average diameter of the guide portion 612 is smaller than the average diameter of the clamping portion 611. The diameter of the clamping portion 611 is larger to facilitate the clamping of the first guide sleeve mechanism 71, and the diameter of the guide portion 612 is smaller to accommodate the horizontal gun drill with a larger aspect ratio. In practical applications, the guide portion 612 can be slender as a whole, and the guide portion 612 can have a certain taper, and its diameter is smaller towards the tip.

[0102] In some embodiments, the support assembly 40 can move along the first horizontal direction and the vertical direction to achieve switching between the avoidance position and the support position. The support assembly 40 can move along the first horizontal direction, for example, along the X direction shown in the figure; the support assembly 40 can also move along the vertical direction, for example, along the Z direction shown in the figure.

[0103] For example, when the horizontal spindle 311 clamps the horizontal gun drill, the support assembly 40 at the avoidance position can move in a vertical direction (for example, can move in the Y direction shown in the figure) and toward the horizontal spindle 311 until the support assembly 40 moves to the support position. In addition, the support assembly 40 can also move in a first horizontal direction (for example, can move in the X direction shown in the figure) to ensure that it can support horizontal gun drills of different lengths, thereby improving the flexibility of the support assembly 40 to adapt to horizontal gun drills of different lengths.

[0104] For example, when the horizontal spindle 311 clamps a horizontal non-gun drilling tool, the support assembly 40 at the stop position can move in the vertical direction (for example, in the Y direction shown in the figure) and away from the horizontal spindle 311 until the support assembly 40 moves to the avoidance position.

[0105] In some embodiments, please refer to Figure 2 and Figure 6 , Figure 6 for Figure 1 The structural schematic diagram of the support assembly 40 of the composite drilling machine tool 100 is shown. The support assembly 40 includes a first slide rail 41, a first slider 42, a second slide rail 43, a second slider 44 and a bracket 45.

[0106] The first slide rail 41 is disposed on the machine base 11. The first slider 42 is disposed on the first slide rail 41, and the first slider 42 can slide in a vertical direction on the first slide rail 41, for example, it can slide in the Z direction shown in the figure. The second slide rail 43 is disposed on the first slider 42. The second slider 44 is disposed on the second slide rail 43, and the second slider 44 can slide in a first horizontal direction on the second slide rail 43, for example, it can slide in the X direction shown in the figure.

[0107] The bracket 45 is connected to the second slider 44 , and the first slide rail 41 , the first slider 42 , the second slide rail 43 and the second slider 44 cooperate to enable the bracket 45 to switch between the avoidance position and the support position.

[0108] The number of the brackets 45 may be one, two, three or four, etc., and is not limited here. It is understandable that the number of the brackets 45 can be adaptively selected according to the length of the horizontal gun drill. When the number of the brackets 45 is greater than or equal to two, the plurality of brackets 45 are distributed on the second slider 44 along the first horizontal direction. Similarly, the interval between two adjacent brackets 45 can also be adaptively adjusted according to the length of the horizontal gun drill clamped by the horizontal spindle 311, that is, the position of each bracket 45 on the second slider 44 along the first horizontal direction is adjusted.

[0109] In some embodiments, the support assembly 40 may further include a first locking device and a second locking device, wherein the first locking device is used to fix the first slider 42 on the first slide rail 41, and the second locking device is used to fix the second slider 44 on the second slide rail 43. When the horizontal spindle 311 clamps the horizontal gun drill to process the workpiece and the bracket 45 is located in the supporting position, the first locking device and the second locking device can be used to fix the position of the bracket 45 to prevent the bracket 45 from accidentally moving during the processing.

[0110] In some embodiments, the bracket 45 includes a mounting portion 451 and a supporting portion 452, and the supporting portion 452 is connected to the mounting portion 451. The mounting portion 451 is connected to the second slider 44, and the supporting portion 452 is used to support the horizontal gun drill when the horizontal spindle 311 clamps the horizontal gun drill.

[0111] The second slider 44 can drive the mounting portion 451 and the supporting portion 452 to move along a first horizontal direction, such as along the X direction shown in the figure. The first slider 42 can drive the mounting portion 451 and the supporting portion 452 to move along a vertical direction, such as along the Z direction shown in the figure.

[0112] In some embodiments, a through hole 452a is formed on the support portion 452. When the horizontal gun drill is clamped by the horizontal spindle 311, the through hole 452a is used to insert the horizontal gun drill. The horizontal gun drill is inserted into the through hole 452a so that the support portion 452 can support the horizontal gun drill, thereby enhancing the rigidity of the horizontal gun drill and reducing the vibration of the horizontal gun drill during the horizontal deep hole drilling process to improve the processing accuracy.

[0113] In some embodiments, the aperture of the through hole 452a is adjustable. It is understandable that horizontal gun drills have different specifications, such as different diameters. The through hole 452a with adjustable aperture enables the bracket 45 to adapt to horizontal gun drills of different diameters, without the need to frequently replace the bracket 45, saving adjustment time and improving production efficiency. In addition, when the horizontal gun drill needs to be disassembled or replaced, increasing the aperture of the through hole 452a can facilitate the removal of the horizontal gun drill.

[0114] In some embodiments, a groove may be formed on the support portion 452, and when the horizontal spindle 311 clamps the horizontal gun drill, the groove is used to support the horizontal gun drill. The groove can be used to place the horizontal gun drill for support to enhance the rigidity of the horizontal gun drill, reduce the vibration of the horizontal gun drill during horizontal deep hole drilling, and improve the processing accuracy. The groove allows the installation of the horizontal gun drill by simply placing the horizontal gun drill into the groove. The opening of the groove may be arranged toward the horizontal spindle 311.

[0115] In some embodiments, the compound drilling machine 100 further includes a vertical slide 52, which is disposed on the machine base 11 and connected to the vertical spindle 321. The vertical slide 52 can move along a first horizontal direction, for example, along the X direction shown in the figure. The vertical slide 52 is used to drive the vertical spindle 321 to move along the first horizontal direction.

[0116] The vertical slide 52 is slidably connected to the machine base 11, for example, the vertical slide 52 can be slidably connected to the machine base 11 via a guide rail. When the vertical slide 52 moves along the first horizontal direction, it can simultaneously drive the vertical spindle 321 to move along the first horizontal direction, so that the vertical spindle 321 is close to or away from the horizontal spindle 311. Among them, the compound drilling machine 100 can also include a servo motor, which can be installed on the machine base 11 or on the vertical slide 52. The servo motor can be used to drive the vertical slide 52 to move along the first horizontal direction.

[0117] When the compound drilling machine 100 needs to perform vertical processing while performing horizontal processing, the vertical slide 52 can drive the vertical spindle 321 to move along the first horizontal direction (for example, along the X direction shown in the figure) and toward the direction close to the horizontal spindle 311, so that the tool on the vertical spindle 321 can perform vertical processing on the workpiece.

[0118] In some embodiments, the compound drilling machine 100 includes a second guide sleeve 62 and a second guide sleeve mechanism 72. The second guide sleeve 62 is disposed above the driving assembly 20, and the second guide sleeve 62 is spaced apart from the first guide sleeve 61. The second guide sleeve 62 can move in a vertical direction, for example, in the Z direction shown in the figure, to adjust the height of the second guide sleeve 62.

[0119] The vertical spindle 321 is used to clamp a vertical gun drill or a vertical non-gun drill tool. When the vertical spindle 321 clamps the vertical gun drill, the second guide sleeve 62 is used for the vertical gun drill to penetrate. In this way, the vertical gun drill clamped by the vertical spindle 321 is guided and positioned by the second guide sleeve 62, so when performing vertical gun drilling processing, the processing accuracy can be improved.

[0120] The second guide sleeve mechanism 72 is slidably connected to the vertical spindle box 32. For example, the second guide sleeve mechanism 72 can be slidably connected to the vertical spindle box 32 through a guide rail. The second guide sleeve 62 is fixedly connected to the second guide sleeve mechanism 72. The second guide sleeve mechanism 72 is used to drive the second guide sleeve 62 to move in the vertical direction, for example, it can move in the Z direction shown in the figure, so as to adjust the height of the second guide sleeve 62.

[0121] The structure of the second guide sleeve mechanism 72 may be the same as that of the first guide sleeve mechanism 71 , and thus the structure of the second guide sleeve mechanism 72 may refer to the description of the first guide sleeve mechanism 71 in the above example.

[0122] In some embodiments, the compound drilling machine 100 further includes a first tool magazine 81 and a second tool magazine 82 .

[0123] The first tool magazine 81 is connected to the machine base 11. The first tool magazine 81 is used to accommodate the tools clamped by the horizontal spindle 311, and the tools include at least a horizontal gun drill and a horizontal milling cutter. It can be understood that different horizontal gun drills can be used for deep hole drilling with different hole diameters and depths. Among them, the first tool magazine 81 can be a fixed row tool magazine or a chain tool magazine.

[0124] Among them. Different horizontal milling cutters can be used for different milling processes. In a feasible embodiment, different cutting tools can be manually selected from the first tool magazine 81 and installed on the horizontal spindle 311 to achieve the required processing technology. In another feasible embodiment, the compound drilling machine 100 can also autonomously select different cutting tools from the first tool magazine 81 according to the processing requirements, and control the selected cutting tools to be installed on the horizontal spindle 311.

[0125] For example, when replacing the tool on the horizontal spindle 311, the support assembly 40 is controlled to move downward to the avoidance position, and then the first guide sleeve mechanism 71 is controlled to move to the left to the avoidance position (at this time, the first guide sleeve 61 installed on the first guide sleeve mechanism 71 needs to be removed), and then the first tool magazine 81 is controlled to rotate to the position where the tool is to be placed, and at the same time, the horizontal spindle 311 is controlled to move to the left until the clamp of the first tool magazine 81 is the same width as the tool handle, and then the first tool magazine 81 is extended so that the clamp of the first tool magazine 81 clamps the tool handle, and the horizontal spindle 311 releases the tool, and then the horizontal spindle 311 moves to the right, and the tool handle is separated from the horizontal spindle 311, and the original tool is disassembled. Subsequently, the first tool magazine 81 is controlled to rotate to the tool removal position, the horizontal spindle 311 moves to the right, and then the horizontal spindle 311 locks the tool, and the first tool magazine 81 is controlled to retreat to complete the installation of the new tool. In this way, the compound drilling machine 100 can realize automatic tool replacement.

[0126] In some embodiments, the first tool magazine 81 may further include a manipulator 811, which is used to clamp the tool. The manipulator 811 can remove the tool from the horizontal spindle 311 or grab a new tool and install it on the horizontal spindle 311. The tool replacement process can refer to the above description. Using the manipulator 811 to realize automatic tool replacement of the compound drilling machine tool 100 can greatly improve the processing efficiency.

[0127] The second tool magazine 82 is connected to the machine base 11 and is spaced apart from the first tool magazine 81. The second tool magazine 82 is used to accommodate the second guide sleeve 62 and the tools clamped by the vertical spindle 321. The tools include at least a vertical gun drill and a vertical milling cutter. It can be understood that different vertical gun drills can be used for deep hole drilling with different hole diameters and depths.

[0128] The second tool magazine 82 can accommodate at least two second guide sleeves 62, and different second guide sleeves 62 are adapted to different vertical gun drills. It can be understood that the vertical gun drill has different specifications, such as different diameters, and the second guide sleeves 62 required to be adapted also need to have different specifications.

[0129] In practical applications, different vertical gun drills and second guide sleeves 62 compatible with the vertical gun drills can be selected according to processing requirements. In practical applications, different second guide sleeves 62 can be manually selected from the guide sleeve magazine 90 and installed on the second guide sleeve mechanism 72; or the compound drilling machine 100 can autonomously select different second guide sleeves 62 from the second tool magazine 82 according to processing requirements and control the selected second guide sleeve 62 to be installed on the second guide sleeve mechanism 72.

[0130] The vertical spindle 321 is also used to clamp a vertical milling cutter to perform milling processing on a workpiece. Different vertical milling cutters can be used for different milling processes. In a feasible embodiment, different cutting tools can be manually selected from the second tool magazine 82 and installed on the vertical spindle 321 to achieve the required processing technology. In another feasible embodiment, the compound drilling machine 100 can also autonomously select different cutting tools from the second tool magazine 82 according to processing requirements, and control the selected cutting tools to be installed on the vertical spindle 321.

[0131] For example, when replacing the tool on the vertical spindle 321, first control the second guide sleeve mechanism 72 to rise to the avoidance position (at this time, the second guide sleeve 62 installed on the second guide sleeve mechanism 72 needs to be removed), and then control the second tool magazine 82 to rotate to the position where the tool is to be placed, and at the same time control the vertical spindle 321 to descend to the same height as the tool magazine clamp and the tool handle, and then the second tool magazine 82 extends out so that the tool magazine clamp clamps the tool handle, and then the vertical spindle 321 releases the tool, and then the vertical spindle 321 rises, and the tool handle is separated from the vertical spindle 321, and the original tool is disassembled. Subsequently, the second tool magazine 82 is controlled to rotate to the tool removal position, the vertical spindle 321 descends, and then the vertical spindle 321 locks the tool and rises, and the second tool magazine 82 is controlled to retreat to complete the installation of the new tool. In this way, the compound drilling machine 100 can realize automatic tool replacement.

[0132] For example, when replacing the second guide sleeve 62, first control the vertical spindle 321 to rise to the highest position, and the second guide sleeve mechanism 72 to fall to the lowest position to ensure that the tool has been detached from the tool magazine, and then rotate the second tool magazine 82 to place the guide sleeve, and then control the vertical spindle 321 to fall (the second guide sleeve mechanism 72 falls at the same time) until the guide sleeve slot and the clip of the second tool magazine 82 are at the same height, and then extend the second tool magazine 82, and then control the vertical spindle 321 to rise (the second guide sleeve mechanism 72 rises at the same time), so that the second guide sleeve 62 is detached from the second guide sleeve mechanism 72, and then the second tool magazine 82 is retracted, and the disassembly of the original second guide sleeve 62 is completed. Subsequently, the tool is replaced. The specific process of replacing the tool can refer to the above description. After the tool is replaced, the vertical spindle 321 (i.e., the Z axis) is similarly controlled to rise to the highest position, the guide sleeve structure 31 is lowered to the lowest position, and then the second tool magazine 82 is rotated to the guide sleeve removal position, and then the vertical spindle 321 is controlled to descend so that the second guide sleeve 62 enters the second guide sleeve mechanism 72, and then the second tool magazine 82 is controlled to retract so that the second guide sleeve 62 is separated from the second tool magazine 82, and the installation of the new second guide sleeve 62 is completed. In this way, the compound drilling machine tool 100 can realize the autonomous control of replacing the second guide sleeve 62.

[0133] The second tool magazine 82 may be a fixed row tool magazine, a chain tool magazine, etc. Preferably, the chain tool magazine can be used to increase the capacity and improve the space utilization, thereby saving space.

[0134] The embodiment of the present application also provides a control method of a composite drilling machine tool 100, which is applied to the composite drilling machine tool 100 of any of the above embodiments. The horizontal spindle 311 of the composite drilling machine tool 100 is used to clamp a horizontal gun drill or a horizontal milling cutter. The control method includes the following steps:

[0135] When the horizontal spindle is clamping the horizontal milling cutter, the support assembly is controlled to move to an avoidance position to avoid the horizontal milling cutter, and the horizontal milling cutter is controlled to perform milling processing on the workpiece;

[0136] Replace the horizontal milling cutter with a horizontal gun drill;

[0137] Control the support assembly of the machine tool to move to the support position to support the horizontal gun drill, and control the horizontal gun drill to perform deep hole drilling on the workpiece.

[0138] The composite drilling machine tool 100 of the embodiment of the present application can perform horizontal milling and horizontal deep hole drilling on the workpiece. Specifically, when the horizontal spindle 311 clamps the horizontal milling cutter, the support assembly 40 is controlled to move downward in the vertical direction to the avoidance position to avoid the horizontal milling cutter, and the horizontal milling cutter is controlled to perform milling on the workpiece. Subsequently, the horizontal milling cutter is replaced with a horizontal gun drill. The operation process of replacing the horizontal gun drill can refer to the description in the above embodiment. The support assembly 40 of the machine tool is controlled to move to the support position to support the horizontal gun drill, and the horizontal gun drill is controlled to perform deep hole drilling on the workpiece.

[0139] It is understandable that the entire process of machining the workpiece may also include controlling the movement of the workpiece, controlling the spatial angle adjustment of the workpiece, aligning the workpiece, and other operations, and these operations may be automatically controlled by the compound drilling machine 100 .

[0140] The composite drilling machine 100 of the present application integrates a vertical spindle box 32 and a horizontal spindle box 31, and can complete the processing in the vertical direction and the first horizontal direction in one clamping of the workpiece, reducing the number of workpiece clamping times to improve processing efficiency. When the horizontal spindle 311 clamps the horizontal gun drill, the support assembly 40 of the composite drilling machine 100 can provide additional support for the horizontal gun drill, effectively reducing the jitter of the horizontal gun drill during processing, thereby improving processing accuracy. During horizontal processing, the support assembly 40 is driven to move by the horizontal crossbeam 51 to support or avoid in the corresponding state, without the need for manual frequent disassembly or removal of the support assembly 40, which is not only easy to operate, but also avoids the problems of time waste and position adjustment errors that may be caused by manual operation, thereby improving processing efficiency and processing accuracy. When the horizontal spindle 311 clamps different tools, the support assembly 40 can move between the support position and the avoidance position to adapt to different processing requirements. Various processing operations can be completed without replacing the compound drilling machine 100 or performing complex setting adjustments, thereby improving the flexibility and versatility of the compound drilling machine 100.

[0141] In the description of this application, it should be understood that terms such as "first" and "second" are only used to distinguish similar objects and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0142] The above is a detailed introduction to the composite drilling machine tool and the control method of the composite drilling machine tool provided in the embodiment of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application. At the same time, for those skilled in the art, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
