Description

Technical Field

[0002] For a traditional deep hole drilling machine tool, when using a gun drill for drilling, it is required that the workpiece surface is a flat surface, and the workpiece surface needs to be parallel to the workbench surface, and the direction of the hole to be machined needs to be perpendicular to the workbench surface. Therefore, the traditional deep hole drilling machine tool cannot drill inclined holes, that is, the direction of the hole to be machined is not perpendicular to the workpiece surface.

[0053] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application

[0054] The embodiment of the present application provides a deep hole drilling machine, which can be used for deep hole machining of workpieces. The deep hole drilling machine in the embodiment of the present application can directly perform inclined hole machining on workpieces and can improve machining efficiency and machining accuracy

[0055] Refer to Figure 1 , Figure 1This is the first structural schematic diagram of the deep hole drilling machine tool 100 provided by the embodiments of the present application.

[0056] The deep hole drilling machine tool 100 includes a base 11 and a column 12. The column 12 is connected to the base 11, and the column 12 can be arranged on one side of the base 11. Among them, the base 11 is placed horizontally, and the column 12 extends vertically upward. The base 11 and the column 12 together play a role in supporting and fixing other structures of the deep hole drilling machine tool 100.

[0057] The deep hole drilling machine tool 100 further includes a driving assembly 20. The driving assembly 20 is integrally arranged on the base 11. A workpiece 61 can be placed on the driving assembly 20. The driving assembly 20 is used to drive the workpiece 61 to move, for example, drive the workpiece 61 to move in the horizontal direction and drive the workpiece 61 to rotate, so as to achieve accurate positioning of the workpiece 61 and facilitate deep hole machining of the workpiece 61.

[0058] Among them, the driving assembly 20 includes a first rotating mechanism 21 and a second rotating mechanism 22. The second rotating mechanism 22 is arranged on the first rotating mechanism 21. The second rotating mechanism 22 is used to carry the workpiece 61, and the second rotating mechanism 22 has a surface for carrying the workpiece 61. The first rotating mechanism 21 can rotate around a horizontal axis, for example, can rotate around the X direction shown in the figure, so as to drive the workpiece 61 to rotate in the horizontal direction. The second rotating mechanism 22 can rotate around its own axis to drive the workpiece 61 to rotate, wherein the own axis passes through the center of the surface carrying the workpiece 61 and is perpendicular to the surface. The rotation axis of the second rotating mechanism 22 intersects and is perpendicular to the rotation axis of the first rotating mechanism 21. The first rotating mechanism 21 can be understood as the A axis of the deep hole drilling machine tool 100, and the second rotating mechanism 22 can be understood as the C axis of the deep hole drilling machine tool 100.

[0059] Therefore, through the cooperation of the first rotating mechanism 21 and the second rotating mechanism 22, the workpiece 61 can be driven to rotate to any spatial angle, realizing the positioning of the workpiece 61 at any spatial angle. Therefore, deep hole machining can be realized for the workpiece 61 at any spatial angle, for example, drilling inclined holes, that is, drilling can also be carried out in a state where the surface of the workpiece 61 is not parallel to the horizontal plane.

[0060] In some embodiments, with reference to Figure 2 , Figure 2 is Figure 1 the structural schematic diagram of the first rotating mechanism 21 of the deep hole drilling machine tool shown. The first rotating mechanism 21 includes a first fixing member 211, a second fixing member 212, and a carrying member 213.

[0061] Among them, the second fixing member 212 is disposed opposite to the first fixing member 211. The first fixing member 211 and the second fixing member 212 are fixedly installed on other structures, for example, fixedly installed on the structure below the first rotating mechanism 21, so as to realize the overall installation and fixation of the first rotating mechanism 21.

[0062] The carrier member 213 is disposed between the first fixing member 211 and the second fixing member 212. One end of the carrier member 213 is rotatably connected to the first fixing member 211, and the other end of the carrier member 213 is rotatably connected to the second fixing member 212. The carrier member 213 can rotate relative to the first fixing member 211 and the second fixing member 212. The second rotating mechanism 22 is disposed on the carrier member 213.

[0063] In practical applications, the carrier member 213 can be rotated by a motor. For example, in a feasible implementation manner, a motor can be disposed inside the second fixing member 212, the output shaft of the motor is connected to one end of the carrier member 213, and the other end of the carrier member 213 is rotatably connected to the first fixing member 211 through a bearing. Thus, the rotation drive of the carrier member 213 can be realized.

[0064] It can be understood that in practical applications, the second rotating mechanism 22 can also be rotated by a motor. For example, in a feasible implementation manner, a motor can be disposed inside the carrier member 213, and the output shaft of the motor is connected to the bottom of the second rotating mechanism 22. Thus, the rotation drive of the second rotating mechanism 22 can be realized.

[0065] In some embodiments, the carrier member 213 includes a bottom 213a, a first side portion 213b, and a second side portion 213c. The first side portion 213b and the second side portion 213c are connected to both sides of the bottom 213a. Among them, the first side portion 213b is connected to the first fixing member 211, and the second side portion 213c is connected to the second fixing member 212. The first side portion 213b and the second side portion 213c extend in the same direction perpendicular to the bottom 213a. For example, both the first side portion 213b and the second side portion 213c extend upward. The carrier member 213 is generally U-shaped as a whole. The bottom 213a, the first side portion 213b, and the second side portion 213c together form an accommodating area 214. The second rotating mechanism 22 is disposed on the bottom 213a and is located in the accommodating area 214.

[0066] Continue to refer to Figure 1 In some embodiments, the driving assembly 20 further includes a first sliding mechanism 23 and a second sliding mechanism 24.

[0067] Among them, the first sliding mechanism 23 is arranged on the base 11. The first sliding mechanism 23 can slide along the first horizontal direction, for example, it can slide along the Y direction shown in the figure. For example, in actual applications, the first sliding mechanism 23 can be slidably connected to the base 11 through a guide rail, and an electric lead screw is used to drive the first sliding mechanism 23 to slide along the Y direction. Thus, the movement and accurate positioning of the workpiece 61 along the Y direction can be realized. The first sliding mechanism 23 can be understood as the Y axis of the deep hole drilling machine tool 100.

[0068] The second sliding mechanism 24 is arranged on the first sliding mechanism 23. The above-mentioned first fixing member 211 and second fixing member 212 are both fixedly connected to the second sliding mechanism 24. The second sliding mechanism 24 can slide along the second horizontal direction, for example, it can slide along the X direction shown in the figure. For example, in actual applications, the second sliding mechanism 24 can be slidably connected to the first sliding mechanism 23 through a guide rail, and an electric lead screw is used to drive the second sliding mechanism 24 to slide along the X direction. Thus, the movement and accurate positioning of the workpiece 61 along the X direction can be realized. The second sliding mechanism 24 can be understood as the X axis of the deep hole drilling machine tool 100.

[0069] Continue to refer to Figure 1 , the deep hole drilling machine tool 100 further includes a bushing 32 and a spindle 42. Among them, the bushing 32 is arranged above the driving assembly 20. The bushing 32 can move in the vertical direction, for example, it can move along the Z direction shown in the figure to adjust the height of the bushing 32. The spindle 42 is arranged above the driving assembly 20. The spindle 42 can move in the vertical direction, for example, it can move along the Z direction shown in the figure to adjust the height of the spindle 42. The spindle 42 is used to clamp the gun drill 43, and the gun drill 43 can pass through the bushing 32 to perform deep hole machining on the workpiece 61.

[0070] It should be noted that in a deep hole drilling machine tool, since the tool used in the deep hole drilling machine tool is a gun drill, and the length-diameter ratio of the gun drill is usually large, which will result in insufficient rigidity of the gun drill. Therefore, a bushing is required to guide and position the gun drill to improve the accuracy of deep hole machining.

[0071] For the deep hole drilling machine tool 100 of the present application, the bushing 32 is used to guide and position the gun drill 43. Therefore, when performing deep hole machining, the machining accuracy can be improved. On the other hand, the deep hole drilling machine tool 100 of the present application can directly perform inclined hole machining on the workpiece, and during the process of inclined hole machining, there is no need to transfer the workpiece between multiple machines and reposition and calibrate the workpiece, and by clamping the workpiece once, straight hole and inclined hole machining of multiple surfaces of the workpiece can be realized on one machine tool. Therefore, the machining efficiency can be improved.

[0072] In some embodiments, the deep hole drilling machine tool 100 further includes a bushing mechanism 31 and a spindle box 41. Among them, the spindle box 41 is slidably connected to the column 12. For example, the spindle box 41 can be slidably connected to the column 12 through a guide rail. The spindle 42 is fixedly connected to the spindle box 41. The spindle box 41 is used to drive the spindle 42 to move in the vertical direction. For example, it can move along the Z direction shown in the figure to adjust the height of the spindle 42. The spindle box 41 can be understood as the Z-axis of the deep hole drilling machine tool 100. The bushing mechanism 31 is slidably connected to the spindle box 41. For example, it can be slidably connected through a guide rail. The bushing 32 is fixedly connected to the bushing mechanism 31. The bushing mechanism 31 is used to drive the bushing 32 to move in the vertical direction to adjust the height of the bushing 32. The bushing mechanism 31 can be understood as the V-axis of the deep hole drilling machine tool 100.

[0073] In an example of practical application, the bushing mechanism 31 as a whole can be U-shaped. The upper ends of the bushing mechanism 31 are respectively slidably connected to both sides of the spindle box 41. A relatively large through hole can be provided at the bottom of the bushing mechanism 31 for clamping the bushing 32. When the bushing 32 is not clamped at the bottom of the bushing mechanism 31, the nose end of the spindle 42 can pass through this through hole.

[0074] In some embodiments, the deep hole drilling machine tool 100 further includes a tool magazine 51 and a bushing magazine 52.

[0075] Among them, the tool magazine 51 is connected to the column 12. The tool magazine 12 is used to accommodate tools, and the tools at least include a gun drill and a milling cutter. It can be understood that different gun drills can be used for deep hole machining with different hole diameters and depths. In the embodiments of the present application, the spindle 42 is also used to clamp the milling cutter to perform milling machining on the workpiece 61. Different milling cutters can be used for different milling machining. In a feasible implementation manner, different tools can be selected from the tool magazine 51 by an operator and installed on the spindle 42 to achieve the required processing technology. In another feasible implementation manner, the deep hole drilling machine tool 100 can also autonomously select different tools from the tool magazine 51 according to the processing requirements and control the selected tools to be installed on the spindle 42.

[0076] For example, when replacing the tool, first control the bushing mechanism 31 to rise to the avoidance position (at this time, the bushing installed on the bushing mechanism 31 needs to be removed), then control the tool magazine 51 to rotate to the position where the tool is to be placed, and at the same time control the spindle to descend to the same height as the tool holder of the tool magazine, then the tool magazine 51 extends, so that the tool holder of the tool magazine clamps the tool holder, then the spindle releases the tool, and then the spindle rises, and the tool holder disengages from the spindle. At this time, the disassembly of the original tool is completed. Subsequently, control the tool magazine 51 to rotate to the tool taking position, the spindle descends, then the spindle locks the tool and rises, and control the tool magazine 51 to retract to complete the installation of the new tool. Thus, the deep hole drilling machine tool 100 can realize autonomous control of tool replacement.

[0077] The guide bushing library 52 is connected to the column 12. The guide bushing library 52 is used to accommodate at least two guide bushings, and different guide bushings are adapted to different gun drills. It can be understood that gun drills have different specifications, such as different diameters, and the required adapted guide bushings also need to have different specifications. In practical applications, different gun drills can be selected according to the processing requirements, and the guide bushings adapted to the gun drills can also be selected. In practical applications, different guide bushings can be manually selected from the guide bushing library 52 and installed on the guide bushing mechanism 31; or the deep hole drilling machine tool 100 can autonomously select different guide bushings from the guide bushing library 52 according to the processing requirements and control the selected guide bushings to be installed on the guide bushing mechanism 31.

[0078] For example, when replacing the guide bushing, first control the spindle box 41 (i.e., the Z-axis) to rise to the highest position, and the guide bushing mechanism 31 to descend to the lowest position to ensure that the tool has disengaged from the tool magazine. Then rotate the guide bushing library 52 to the guide bushing placement position. Subsequently, control the spindle box 41 to descend (the guide bushing mechanism 31 descends simultaneously) until the guide bushing slot is at the same height as the clip of the guide bushing library 52. Then extend the guide bushing library 52, and then control the spindle box 41 to rise (the guide bushing mechanism 31 rises simultaneously) to disengage the guide bushing from the guide bushing mechanism 31. Then the guide bushing library 52 retracts, and at this time, the disassembly of the original guide bushing is completed. Subsequently, replace the tool, and the specific process of replacing the tool can refer to the description above. After replacing the tool, similarly control the spindle box 41 (i.e., the Z-axis) to rise to the highest position, and the guide bushing structure 31 to descend to the lowest position. Then rotate the guide bushing library 52 to the guide bushing picking position, and then control the spindle box 41 to descend to make the guide bushing enter the guide bushing mechanism 31. Then control the guide bushing library 52 to retract to disengage the guide bushing from the guide bushing library 52. At this time, the installation of the new guide bushing is completed. Thus, the deep hole drilling machine tool 100 can autonomously control the replacement of the guide bushing.

[0079] It can be understood that in practical applications, the tool magazine 51 and the guide bushing library 52 can be respectively arranged on different sides of the column 12, as Figure 1 shown; or the tool magazine 51 and the guide bushing library 52 can be arranged on the same side of the column 12.

[0080] In some embodiments, the distance between the tool magazine 51 and the base 11 is greater than the distance between the guide bushing library 52 and the base 11. That is, the height of the tool magazine 51 is greater than the height of the guide bushing library 52.

[0081] Refer to Figure 3 and Figure 4 , Figure 3 which is Figure 1 a schematic structural view of the guide bushing 32 of the deep hole drilling machine tool shown, Figure 4 and Figure 3 is a cross-sectional view of the guide bushing 32 shown.

[0082] The guide sleeve 32 includes a clamping portion 321 and a guiding portion 322. The clamping portion 321 is for being clamped by the guide sleeve mechanism 31. The guiding portion 322 is for guiding the gun drill 43.

[0083] Wherein, the clamping portion 321 includes a first end 321a and a second end 321b which are oppositely arranged along the axis. The guiding portion 322 is connected to the second end 321b and extends from the second end 321b. The average diameter of the guiding portion 322 is smaller than the average diameter of the clamping portion 321. In practical applications, the guiding portion 322 can be overall slender, and the guiding portion 322 can have a certain taper, and its diameter becomes smaller towards the tip.

[0084] As Figure 4 shown, the guiding portion 322 is provided with a through guiding hole 322a. The guiding hole 322a is for the gun drill 43 to pass through. The clamping portion 321 is provided with an axial groove 321c. The groove 321c penetrates the first end 321a and communicates with the guiding hole 322a.

[0085] In some embodiments, referring to Figure 5 , Figure 5 is the second structural schematic diagram of the deep hole drilling machine tool 100 provided by the embodiment of the present application. Figure 5 The shown deep hole drilling machine tool 100 is different from the Figure 1 shown deep hole drilling machine tool 100 in that: the gun drill 43 clamped by the main shaft 42 is replaced with a milling cutter 44. The milling cutter 44 can perform milling processing on the workpiece 61.

[0086] For the deep hole drilling machine tool 100 of the present application, on the one hand, through the cooperation of the first rotating mechanism 21 and the second rotating mechanism 22, the workpiece 61 can be driven to rotate to any spatial angle, so that deep hole processing can be realized at any spatial angle of the workpiece 61, for example, drilling inclined holes; on the other hand, the gun drill 43 is guided and positioned by the guide sleeve 32, so that the processing accuracy can be improved during deep hole processing; on the third hand, during the process of drilling inclined holes on the workpiece 61, there is no need to transfer the workpiece between multiple machines and reposition and calibrate the workpiece, and through one-time clamping of the workpiece, straight holes and inclined holes can be processed on multiple surfaces of the workpiece on one machine tool, so that the processing efficiency can be improved.

[0087] The embodiment of the present application also provides a control method for a deep hole drilling machine tool, which is applied to the deep hole drilling machine tool 100 in any of the above embodiments. The main shaft of the deep hole drilling machine tool 100 is for clamping a gun drill or a milling cutter. Wherein, the control method includes the following steps:

[0088] In the state where the main shaft clamps the milling cutter, control the milling cutter to perform milling processing on the workpiece to machine a plane on the workpiece;

[0089] Replace the milling cutter with a gun drill;

[0090] Control the movement of the bushing of the machine tool until the bottom of the bushing abuts against this plane;

[0091] Control the gun drill to pass through the bushing and perform deep hole machining on the workpiece with this plane as the machining surface.

[0092] The deep hole drilling machine tool 100 of the embodiment of the present application can perform milling machining and deep hole machining on the workpiece 61. Refer to Figure 6 , Figure 6 which is a schematic structural diagram of the workpiece 61 of the deep hole drilling machine tool provided by the embodiment of the present application.

[0093] Specifically, the deep hole drilling machine tool 100 can first replace the milling cutter 44. In the state where the milling cutter 44 is clamped by the main shaft 42 (as Figure 5 shown), control the milling cutter 44 to perform milling machining on the workpiece 61 to machine a plane 611 on the workpiece 61. Subsequently, replace the milling cutter 44 with a gun drill 43. The operation process of replacing the gun drill can refer to the description in the above embodiment. Subsequently, control the movement of the bushing 32 of the machine tool until the bottom of the bushing 32 abuts against the plane 611. In the state where the gun drill 43 is clamped by the main shaft 42 (as Figure 1 shown), control the gun drill 43 to pass through the bushing 32 and perform deep hole machining on the workpiece 61 with the plane 611 as the machining surface, and the deep hole machined is shown as 612 in the figure. It can be understood that during the entire process of machining the workpiece 61, operations such as controlling the movement of the workpiece 61, controlling the spatial angle adjustment of the workpiece 61, and aligning the workpiece 61 can also be included, and these operations can be automatically controlled by the deep hole drilling machine tool 100 to perform.

[0094] The deep hole drilling machine tool 100 of the present application first performs milling machining on the workpiece 61 and then performs deep hole machining. Therefore, deep hole machining can be realized at any spatial angle of the workpiece 61, such as drilling inclined holes; in addition, the gun drill 43 is guided and positioned by the bushing 32. Therefore, during deep hole machining, the machining accuracy can be improved; in addition, during the process of drilling inclined holes on the workpiece 61, there is no need to transfer the workpiece between multiple machines and reposition and calibrate the workpiece, and by clamping the workpiece once, straight holes and inclined holes can be machined on multiple surfaces of the workpiece on one machine tool. Therefore, the machining efficiency can be improved.

[0095] In the description of the present application, it should be understood that terms such as "first", "second", etc. are only used to distinguish similar objects and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

Specific examples are used herein to elaborate on the principle and implementation manner 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 manner and application scope.
