Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and in particular to a machine tool. Background Technology

[0002] Vertical deep hole drilling machines are common mechanical devices used for drilling workpieces. A typical vertical deep hole drilling machine usually includes a worktable, a machining mechanism, and a translation mechanism. The translation mechanism drives the machining mechanism to move in different directions to achieve drilling at different positions on the workpiece placed on the worktable. Because the worktable is usually mounted on the translation mechanism, its size is limited, thus restricting the size of the workpieces that can be drilled. Furthermore, the worktable's placement on the translation mechanism also amplifies accuracy errors; therefore, these problems urgently need to be addressed. Utility Model Content

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0021] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal," etc., indicate the orientation or state relationship based on the orientation or state relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0022] Furthermore, in addition to indicating location or state relationships, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0023] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] Furthermore, unless otherwise explicitly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.

[0026] Please see Figure 1This application provides a machine tool 100 for drilling parts. As a specific example, in this embodiment, the machine tool 100 is a vertical five-axis deep hole drilling machine 100. In other embodiments, the machine tool 100 can be any type of machine tool 100 for machining deep holes, such as a deep hole drilling machine, a deep hole processing machine tool 100, or a CNC deep hole drilling machine tool 100. This embodiment does not limit the specific type of machine tool 100.

[0027] Please see Figure 1 and Figure 2 The machine tool 100 includes a base 10, a mounting bracket 11, a first drive mechanism 12, a second drive mechanism 13, a third drive mechanism 14, a drilling mechanism 15, a worktable 16, a first rotary drive mechanism 17, and a second rotary drive mechanism.

[0028] The base 10 is disposed at the bottom of the machine tool 100 for mounting and supporting other structures and components of the machine tool 100. The mounting bracket 11 includes a mounting base 111, a first mounting member 112, a second mounting member 113, and a third mounting member 114. The mounting base 111 is generally a block structure and is connected to the base 10. The mounting base 111 is used to connect and mount other structures of the machine tool 100.

[0029] The first drive mechanism 12 is connected between the first mounting member 112 and the mounting base 111 to drive the first mounting member 112 to move along the first direction Y. The first mounting member 112 can be any shape, such as a block structure or a plate structure. The first mounting member 112 is used to connect and install other structures of the machine tool 100. The first direction Y can be any direction; as a specific example, in this embodiment, the first direction Y is approximately horizontal.

[0030] The second drive mechanism 13 is connected between the first mounting member 112 and the second mounting member 113 to drive the second mounting member 113 to move along the second direction X. The second mounting member 113 can be any shape, such as a block structure or a plate structure. The second mounting member 113 is used to connect and mount other structures of the machine tool 100. The second direction X can be any direction. As a specific example, in this embodiment, the second direction X is approximately a horizontal direction that is different from the first direction Y.

[0031] The third drive mechanism 14 is connected between the second mounting member 113 and the third mounting member 114 to drive the third mounting member 114 to move along the third direction Z. The third mounting member 114 can be any shape, such as a block structure or a plate structure. The third mounting member 114 is used to connect and mount other structures of the machine tool 100. The third direction Z can be any direction. As a specific example, in this embodiment, the second direction Z is approximately vertical.

[0032] The drilling mechanism 15 is a specific mechanism of the machine tool 100 used for drilling the workpiece to be processed. The drilling mechanism 15 is connected to the third mounting member 114. The drilling mechanism 15 includes a connected drive assembly 151, a drive motor 152, and a cutting tool 153. The drive motor 152 is connected to the drive assembly 151, and the cutting tool 153 is detachably connected to the output shaft of the drive motor 152 and extends along the third direction Z. The drive assembly 151 is used to drive the cutting tool 153 to move along the third direction Z. The cutting tool 153 is the specific structure of the machine tool 100 used for drilling operations. It can be a gun drill, a reamer, etc., and the user can replace different types of cutting tools 153 as needed. The cutting tool 153 extending along the third direction Z can be understood as: the length direction of the cutting tool 153 extends approximately along the third direction Z. When the drilling mechanism 15 is working, the drive assembly 151 drives the cutting tool 153 to move along the third direction Z, and at the same time, the drive motor 152 drives the cutting tool 153 to rotate, thereby drilling the workpiece to be processed located below the cutting tool 153.

[0033] The worktable 16 is connected to the base 10 and is located below the tool 153. The worktable 16 is used to place the part to be processed. The first rotary drive mechanism 17 is connected between the base 10 and the worktable 16 to drive the worktable 16 to rotate in the second direction X. It should be noted that "the first rotary drive mechanism 17 drives the worktable 16 to rotate in the second direction X" can be understood as: the rotation axis of the first rotary drive mechanism 17 driving the worktable 16 to rotate is the second direction X.

[0034] The second rotary drive mechanism is connected between the first rotary drive mechanism 17 and the worktable 16 to drive the worktable 16 to rotate about the third direction Z. The first direction Y, the second direction X, and the third direction Z are all different. It should be noted that "the second rotary drive mechanism drives the worktable 16 to rotate about the third direction Z" can be understood as: the rotation axis of the second rotary drive mechanism driving the worktable 16 to rotate is the third direction Z.

[0035] The machine tool 100 is equipped with a first drive mechanism 12, a second drive mechanism 13 and a third drive mechanism 14. The first drive mechanism 12 can drive the drilling mechanism 15 to move along the first direction Y, the second drive mechanism 13 can drive the drilling mechanism 15 to move along the second direction X, and the third drive mechanism 14 can drive the drilling mechanism 15 to move along the third direction Z. The first direction Y, the second direction X and the third direction Z are different from each other, so the drilling mechanism 15 can move in three different directions. Since the machine tool 100 is also equipped with a first rotary drive mechanism 17 and a second rotary drive mechanism, the first rotary drive mechanism 17 can drive the worktable 16 to rotate in the second direction X as the axial direction, and the second rotary drive mechanism can drive the worktable 16 to rotate in the third direction Z as the axial direction. The worktable 16 is mounted on the base 10, so it can rotate in two different directions. Therefore, when the workpiece to be processed is placed on the worktable 16 for drilling, by adjusting the positions of the drilling mechanism 15 and the worktable 16, drilling can be performed at any position on the workpiece, greatly satisfying diverse drilling needs and improving production efficiency. Furthermore, since the worktable 16 is mounted on the base 10 and has no linkage with the first drive mechanism 12, the second drive mechanism 13, and the third drive mechanism 14, the volume of the worktable 16 can be appropriately increased to accommodate larger workpieces. Moreover, the movement of the drilling mechanism 15 and the worktable 16 do not affect each other, thus not affecting the machining accuracy of the drilling operation and effectively improving drilling quality.

[0036] Please see Figure 1 and Figure 4 In some embodiments, the first drive mechanism 12 includes a first drive motor 121, a first lead screw 122, and a first nut seat (not shown in the figure). The first drive motor 121 is mounted on a mounting base 111, the first lead screw 122 is rotatably connected to the mounting base 111 and connected to the output shaft of the first drive motor 121, the first lead screw 122 extends along a first direction Y, the first nut seat is threaded onto the first lead screw 122, and the first mounting member 112 is connected to the first nut seat. With the above configuration, when the first drive motor 121 drives the first lead screw 122 to rotate, since the first nut seat is restricted from rotating, the first nut seat will drive the first mounting member 112 to move along the length direction of the first lead screw 122 (i.e., the first direction Y), thereby realizing the position adjustment of the first mounting member 112 and other structures connected to the first mounting member 112 to meet the requirements of hole drilling.

[0037] In some embodiments, the machine tool 100 further includes a plurality of first guide rails 1112, which are disposed on the mounting base 111 along the first direction Y. The plurality of first guide rails 1112 are parallel to each other and spaced apart. The first mounting member 112 is slidably connected to the plurality of first guide rails 1112. As a specific example, in this embodiment, four first guide rails 1112 are provided. In other embodiments, the first guide rails 1112 can be two, three, five, or any other number. Through the above arrangement, the first guide rails 1112 can guide the movement of the first mounting member 112, thereby improving the stability and smoothness of the movement of the first mounting member 112 along the first direction Y, and also improving the structural strength of the machine tool 100.

[0038] In some embodiments, the second drive mechanism 13 includes a second drive motor 131, a second lead screw 132, and a second nut seat (not shown in the figure). The second drive motor 131 is mounted on the first mounting member 112, the second lead screw 132 is rotatably connected to the first mounting member 112 and connected to the output shaft of the second drive motor 131, the second lead screw 132 extends along a second direction X, the second nut seat is threaded onto the second lead screw 132, and the second mounting member 113 is connected to the second nut seat. With the above configuration, when the second drive motor 131 drives the second lead screw 132 to rotate, since the second nut seat is restricted from rotation, the second nut seat will drive the second mounting member 113 to move along the length direction of the second lead screw 132 (i.e., the second direction X), thereby realizing the position adjustment of the second mounting member 113 and other structures connected to the second mounting member 113 to meet the requirements of hole drilling.

[0039] In some embodiments, the third drive mechanism 14 includes a third drive motor 141, a third lead screw 142, and a third nut seat (not shown in the figure). The third drive motor 141 is mounted on the second mounting member 113, the third lead screw 142 is rotatably connected to the second mounting member 113 and connected to the output shaft of the third drive motor 141, the third lead screw 142 extends along the third direction Y, the third nut seat is threaded onto the third lead screw 142, and the third mounting member 114 is connected to the third nut seat. With the above configuration, when the third drive motor 141 drives the third lead screw 142 to rotate, since the third nut seat is restricted from rotation, the third nut seat will drive the third mounting member 114 to move along the length direction of the third lead screw 142 (i.e., the third direction Z), thereby realizing the position adjustment of the third mounting member 114 and other structures connected to the third mounting member 114 to meet the requirements of hole drilling.

[0040] Please see Figure 1 and Figure 2The drilling mechanism 15 also includes a first mounting bracket 154, a second mounting bracket 155, a guide sleeve 156, a guide sleeve flange, and a guide sleeve insert. Both the first mounting bracket 154 and the second mounting bracket 155 are supports. The second mounting bracket 155 is connected to the third mounting member 114 and can move synchronously with the third mounting member 114. The first mounting bracket 154 is connected to the second mounting bracket 155 via a drive assembly 151. Under the drive of the drive assembly 151, the first mounting bracket 154 can move relative to the second mounting bracket 155 along a third direction Z. The first mounting bracket 154 has a mounting notch 1541, at least a portion of the structure of the second mounting bracket 155 is accommodated within the mounting notch 1541, and a drive motor 152 is connected to the second mounting bracket 155. The guide sleeve 156 is located at the end of the first mounting bracket 154 facing the worktable 16, and the cutting tool 153 rotatably passes through the guide sleeve 156. The guide sleeve insert is detachably mounted on the first mounting bracket 154, the guide sleeve flange is detachably mounted on the guide sleeve insert, the guide sleeve insert is disposed between the first mounting bracket 154 and the guide sleeve flange, and the guide sleeve flange is disposed between the guide sleeve insert and the guide sleeve 156. In this embodiment, the guide sleeve 156 is generally cylindrical in shape and is detachably embedded in the first mounting bracket 154. Specifically, the guide sleeve 156 may have a rotating shaft inside, with the central opening of the rotating shaft having an axial direction of the third direction Z. The tool 153 passes through the central opening of the rotating shaft to achieve a rotational connection with the guide sleeve 156, but at the same time, the tool 153 can also move relative to the guide sleeve 156 along the third direction Z.

[0041] With the above configuration, when the drilling mechanism 15 is working, the drive assembly 151 drives the second mounting bracket 155, the drive motor 152, and the cutting tool 153 to move synchronously along the third direction Z. Simultaneously, the drive motor 152 drives the cutting tool 153 to rotate, thereby achieving drilling of the workpiece on the worktable 16. Because of the guide sleeve 156, the cutting tool 153 is limited, ensuring that the cutting tool 153 extends as far as possible along the third direction Z, thus reducing problems such as reduced drilling accuracy caused by tool skew. Furthermore, because of the guide sleeve insert, online boring can be performed on the guide sleeve insert, which helps improve the center accuracy between the guide sleeve 156 and the cutting tool 153, ensuring that the cutting tool 153 can move more accurately and smoothly along the third direction Z. Because of the guide sleeve flange, the guide sleeve flange can withstand the wear generated during long-term disassembly and replacement of the guide sleeve 156. When the wear is severe, the guide sleeve flange can be replaced without replacing the guide sleeve insert and re-boring, reducing equipment operating costs.

[0042] In some embodiments, the drive assembly 151 includes a drive assembly motor and a drive assembly lead screw. The drive assembly motor is located at the end of the first mounting bracket 154 away from the worktable 16, and the output shaft of the drive assembly motor extends along the third direction Z and faces the side closer to the worktable 16. The drive assembly lead screw is coaxially connected to the output shaft of the drive assembly motor and is threaded through the second mounting bracket 155. With the above arrangement, when the output shaft of the drive assembly motor rotates, the drive assembly lead screw will rotate. Since the second mounting bracket 155 is restricted by the third connector 114 and cannot rotate, the second mounting bracket 155, the guide sleeve 156, and the drive motor 152 can move synchronously along the third direction Z relative to the first mounting bracket 154 and the tool 153, thereby realizing the adjustment of the relative position of the tool 153 and the guide sleeve 156, so as to facilitate the disassembly, assembly, and replacement of the tool 153 and the guide sleeve 156.

[0043] Please see Figure 1 and Figure 3 In some embodiments, at least a portion of the guide sleeve 156 protrudes from the surface of the first mounting bracket 154 toward the worktable 16. Specifically, at least a portion of the guide sleeve 156 protrudes from the surface of the first mounting bracket 154 facing the worktable 16. With the above arrangement, when the machine tool 100 is working, the third drive mechanism 14 drives the drilling mechanism 15 to move as a whole along the third direction (Z) toward the worktable 16 until the portion of the guide sleeve 156 protruding from the first mounting bracket 154 abuts against the workpiece to be processed on the worktable 16 and stops moving. Then, the drive assembly 151, in conjunction with the drive motor 152, causes the tool 153 to continue moving along the third direction (Z) toward the workpiece to be processed, thereby realizing drilling. The guide sleeve 156 can not only improve the stability of the workpiece to be processed on the worktable 16, but also improve the stability of the drilling mechanism 15 itself, so that the tool 153 can smoothly drill through the surface of the workpiece to complete the drilling process.

[0044] Please see Figure 1 and Figure 2In some embodiments, the first rotary drive mechanism 17 includes a mounting shell 171, a first rotary drive component, and a connecting component 172. The mounting shell 171 is a housing with a hollow interior and is connected to the base 10. In this embodiment, two mounting shells 171 are provided, and the two mounting shells 171 are arranged at intervals relative to each other along the second direction X. The first rotary drive component is disposed inside the mounting shell 171. The first rotary drive component can be a single motor 152, a dual motor 152, etc. In this embodiment, the first rotary drive component is a dual motor 152. The connecting component 172 is a connecting structure. In this embodiment, the connecting component 172 is a hollow shell structure that is generally elongated. The connecting component 172 is connected to the output shaft of the first rotary drive component, and the connecting component 172 is rotatably connected to the mounting shell 171. The output shaft of the first rotary drive component extends along the second direction X. The worktable 16 is disposed on the side of the connecting component 172 facing the tool 153.

[0045] With the above configuration, the first rotary drive unit rotates in the second direction X as the axis through the drive connector 172, thereby causing the worktable 16 set on the connector 172 to rotate in the second direction X as the axis. This allows the position and angle of the workpiece to be processed placed on the worktable 16 relative to the tool 153 to be adjusted, thus enabling drilling of the workpiece at multiple angles and positions, which is convenient to operate.

[0046] In some other embodiments, a positioning mechanism is provided on the worktable 16. The positioning mechanism may be a gripper, a clamping component, or a similar mechanism, which is used to fix the position of the workpiece to be processed placed on the worktable 16 to prevent the workpiece from moving accidentally during the processing and causing an accident.

[0047] In some embodiments, the second rotary drive mechanism includes a second rotary drive member (not shown in the figure). In this embodiment, the second rotary drive member is a motor 152. The connector 172 has a receiving cavity (not shown in the figure), and the second rotary drive member is housed in the receiving cavity. The output shaft of the second rotary drive member is connected to the worktable 16, and the output shaft of the second rotary drive member extends along the third direction Y. With the above configuration, when the second rotary drive member is started, it can directly drive the worktable 16 to rotate in the third direction Y as the axial direction. Since the second rotary drive member is located in the receiving cavity inside the connector 172, when the first rotary drive mechanism 17 drives the connector 172 and the worktable 16 to rotate in the second direction X as the axial direction, the second rotary drive mechanism can move synchronously with the connector 172, that is, it will not affect the rotational drive of the worktable 16 by the second rotary drive member.

[0048] Please see Figure 1 , Figure 2 and Figure 3In some embodiments, the machine tool 100 further includes an automatic tool changer 18 and a fourth drive mechanism (not shown in the figure). The automatic tool changer 18 may be an automatic tool changer (ATC), and the fourth drive mechanism is connected between the automatic tool changer 18 and the base 10 to drive the automatic tool changer 18 to move along the first direction Y. The automatic tool changer 18 is equipped with various types of cutting tools and guide sleeves for adaptive replacement of cutting tools 153 and guide sleeves 156 according to production needs. The mounting base 111 has a clearance space 1111, which is specifically a space area opened in the middle of the mounting base 111, and the clearance space 1111 is arranged opposite to the worktable 16 along the first direction Y. The fourth drive mechanism is housed in the clearance space 1111 and can drive the automatic tool changer 18 to move into and out of the clearance space 1111.

[0049] With the above setup, when the user needs to replace the tool 153 on the drilling mechanism 15, the first mounting bracket 154 and guide sleeve 156 are first moved to the bottom along the third direction Z by the drive assembly 151. At this time, the guide sleeve 156 will separate from the tool 153. Then, the automatic tool changer 18 is moved out of the clearance space 1111 along the first direction Y to a position close to the tool 153 by the fourth drive mechanism. The automatic tool changer 18 then automatically replaces the tool 153. After the tool 153 is replaced, the fourth drive mechanism moves the automatic tool changer 18 back into the clearance space 1111 to avoid affecting the normal operation of the drilling mechanism 15. Finally, the drive assembly 151 drives the first mounting bracket 154 and guide sleeve 156 to move upward along the third direction Z, so that the tool 153 passes through the guide sleeve 156 again, thus completing the automatic replacement of the tool 153. The above process of replacing the tool 153 can be fully automated, greatly improving production efficiency and providing convenience.

[0050] When the user needs to replace the guide sleeve 156 on the drilling mechanism 15, the first mounting bracket 154 and the guide sleeve 156 are first moved to the bottom along the third direction Z by the drive assembly 151. At this time, the guide sleeve 156 will separate from the tool 153. Then, the automatic tool changer 18 is moved out of the clearance space 1111 along the first direction Y to a position close to the guide sleeve 156 by the fourth drive mechanism. The automatic tool changer 18 then automatically replaces the guide sleeve 156. After the guide sleeve 156 is replaced, the fourth drive mechanism moves the automatic tool changer 18 back into the clearance space 1111 to avoid affecting the normal operation of the drilling mechanism 15. Finally, the drive assembly 151 drives the first mounting bracket 154 and the guide sleeve 156 to move upward along the third direction Z, so that the tool 153 passes through the guide sleeve 156 again, thus completing the automatic replacement of the guide sleeve 156. The above process of replacing the guide sleeve 156 can be fully automated, greatly improving production efficiency and providing convenience.

[0051] In some embodiments, the fourth drive mechanism includes a fourth drive motor, a fourth lead screw, and a fourth nut seat (none shown in the figures). The fourth drive motor is mounted on the base 10, the fourth lead screw is rotatably connected to the base 10 and connected to the output shaft of the fourth drive motor, the fourth lead screw extends along a first direction Y, the fourth nut seat is threaded onto the fourth lead screw, and the automatic tool changer is connected to the fourth nut seat. With the above configuration, when the fourth drive motor starts, it drives the fourth lead screw to rotate, thereby causing the fourth nut seat to move the automatic tool changer 18 along the fourth lead screw, so as to achieve position adjustment of the automatic tool changer 18.

[0052] In some embodiments, the machine tool 100 further includes an automatic door (not shown) disposed on the mounting base 111, located between the clearance space 1111 and the worktable 16. The automatic door is electrically connected to a controller and can automatically open and close according to the controller's instructions. When the automatic door is closed, it isolates the automatic tool changer 18 located in the clearance space 1111 from the worktable 16. When the automatic door is open, a fourth drive mechanism can drive the automatic tool changer 18 to move into or out of the clearance space 1111.

[0053] With the above configuration, when the machine tool 100 needs to change the tool 153, the automatic door will automatically open, allowing the fourth drive mechanism to move the automatic tool changer 18 out of the clearance space 1111 for automatic tool 153 replacement in the drilling mechanism 15. After the tool 153 replacement is complete, the fourth drive mechanism moves the automatic tool changer 18 back into the clearance space 1111, and the automatic door automatically closes. This separates the automatic tool changer 18 from the drilling mechanism 15, preventing waste chips generated during drilling from splashing into the clearance space 1111, thus protecting the fourth drive mechanism and the automatic tool changer 18. Furthermore, since the machine tool 100 needs to spray cutting fluid onto the drilling area of ​​the drilling mechanism 15 for lubrication and cooling during operation, the automatic door also isolates the splashed cutting fluid, preventing it from contaminating the automatic tool changer 18 and other mechanisms.

[0054] Please see Figure 1 and Figure 4 In some embodiments, the machine tool 100 further includes a suction mechanism 21 for recycling cutting fluid. The suction mechanism 21 includes a suction port, a delivery pipe 212, a negative pressure pump, and a storage tank (not shown). The suction port is located on the side of the mounting base 111 facing the worktable 16. The delivery pipe 212 passes through the mounting base 111, the negative pressure pump is mounted on the delivery pipe 212, and the storage tank is located in a cavity inside the base 10. One end of the delivery pipe 212 communicates with the suction port, and the other end communicates with the storage tank. With this configuration, when the drilling mechanism 15 is performing drilling, the mist-like cutting fluid floating around the worktable 16 can enter the delivery pipe 212 through the suction port under the action of the negative pressure pump, and is ultimately delivered to the storage tank for storage. This allows for the recycling and utilization of the cutting fluid, which not only contributes to a cleaner working environment but also saves material costs.

[0055] In some embodiments, multiple liquid inlets are provided, and the multiple liquid inlets are distributed in an array. The above arrangement allows the liquid inlets to have a filtering effect, so as to prevent other impurities in the air from being sucked into the infusion pipe 212 and contaminating the recovered cutting fluid.

[0056] Please see Figure 1 and Figure 2In some embodiments, the base 10 has a collection trough 101 for collecting debris. When the machine tool 100 is in operation, the collection trough 101 is located below the worktable 16. It should be noted that "when the machine tool 100 is in operation" refers to the position of the machine tool 100 in normal operation. The machine tool 100 also includes a chip removal mechanism 20, which includes a conveying component 201 and a chip removal pipe 202. One end of the chip removal pipe 202 communicates with the collection trough 101, and the other end extends to one side outside the base 10. The conveying component 201 is disposed in the collection trough 101 to transport the debris in the collection trough 101 to the chip removal pipe 202. In this embodiment, the conveying component 201 is a spiral conveying rod, which is driven to rotate by a motor to realize the conveying of debris in the collection trough 101.

[0057] With the above configuration, the collection tank 101 is used to collect the debris generated during the drilling process. Then, the debris in the collection tank 101 is transported to the chip discharge pipe 202 located on one side of the base 10 by the conveyor 201, so that the workers can clean up the debris concentrated in the chip discharge pipe 202. This can improve the efficiency of debris collection and ensure cleanliness and hygiene.

[0058] Please see Figure 1 In some embodiments, the machine tool 100 further includes an automatic tool setting device 22, which can be mounted on the mounting base 111. The automatic tool setting device 22 can be an automatic tool setter, used to measure and compensate the parameters of the tool 153 to improve machining accuracy. Specifically, before drilling, through the coordinated operation of the first drive mechanism 12, the second drive mechanism 13, the third drive mechanism 14, and the drive assembly 151, the tool 153 of the drilling mechanism 15 can be moved to the position of the automatic tool setting device 22 and the automatic tool setting is completed. The operation is simple, fast, and efficient.

[0059] Please see Figure 1 In some embodiments, when the machine tool 100 is in operation, the end of the chip removal pipe 202 away from the base 10 is bent upwards. With the above arrangement, since the cutting fluid inevitably flows into the collection tank 101 during the drilling process, the chips in the collection tank 101 will be mixed with a certain amount of cutting fluid. Since the end of the chip removal pipe 202 away from the base 10 is bent upwards, the chips and cutting fluid transported to the chip removal pipe 202 by the conveyor 201 will not flow out of the chip removal pipe 202 at will and pollute the environment, thus improving the cleanliness of the processing site.

[0060] In some embodiments, the chip removal mechanism 20 further includes a drain pipe, a filter element, and an end cap (all not shown in the figures). One end of the drain pipe is connected to the chip removal pipe 202, and the end cap is detachably connected to the end of the drain pipe away from the chip removal pipe 202. The filter element is disposed inside the drain pipe and can be a filter structure such as a filter screen. With the above configuration, the drain pipe can discharge the cutting fluid in the chip removal pipe 202, and the filter element can trap chips to prevent them from being discharged from the drain pipe, thereby enabling further recovery of the cutting fluid and reducing production costs.

[0061] In summary, the embodiments of this application provide a machine tool 100. The machine tool 100 is provided with a first drive mechanism 12, a second drive mechanism 13 and a third drive mechanism 14. The first drive mechanism 12 can drive the drilling mechanism 15 to move along the first direction Y, the second drive mechanism 13 can drive the drilling mechanism 15 to move along the second direction X, and the third drive mechanism 14 can drive the drilling mechanism 15 to move along the third direction Z. The first direction Y, the second direction X and the third direction Z are different from each other. Therefore, the drilling mechanism 15 can realize movement in three different directions. Since the machine tool 100 is also equipped with a first rotary drive mechanism 17 and a second rotary drive mechanism, the first rotary drive mechanism 17 can drive the worktable 16 to rotate in the second direction X as the axial direction, and the second rotary drive mechanism can drive the worktable 16 to rotate in the third direction Z as the axial direction. The worktable 16 is mounted on the base 10, so it can rotate in two different directions. Therefore, when the workpiece to be processed is placed on the worktable 16 for drilling, by adjusting the positions of the drilling mechanism 15 and the worktable 16, drilling can be performed at any position on the workpiece, greatly satisfying diverse drilling needs and improving production efficiency. Furthermore, since the worktable 16 is mounted on the base 10 and has no linkage with the first drive mechanism 12, the second drive mechanism 13, and the third drive mechanism 14, the volume of the worktable 16 can be appropriately increased to accommodate larger workpieces. Moreover, the movement of the drilling mechanism 15 and the worktable 16 do not affect each other, thus not affecting the machining accuracy of the drilling operation and effectively improving drilling quality.
