Description

Technical Field

[0001] This application belongs to the technical field of machine tools, specifically relating to a horizontal five-axis turning and milling composite machine tool. Background Technology

[0002] A horizontal five-axis turning and milling composite machine tool is a composite machining center with its spindle (usually a turning spindle) arranged in a horizontal direction. It combines two core machining methods: turning (rotating the workpiece) and milling (rotating the cutting tool), and can complete the turning and milling operations of complex workpieces in a single setup.

[0003] Currently, horizontal five-axis turning and milling composite machine tools typically include a base, a column located at one end of the base, a worktable slidably connected to the base in the horizontal direction, and a crossbeam slidably connected to the column in the vertical direction. The crossbeam is equipped with a machining mechanism for processing workpieces. To increase the stability of the column, a wall-type column is usually used. While this increases the stability of the column, when the worktable moves towards a position close to the column, the wall-type column can interfere with the worktable, thus affecting the range of motion of the worktable. At the same time, large clumps of chips may be generated during the processing of workpieces. Because the chip discharge port of existing horizontal five-axis turning and milling composite machine tools is small, large clumps of chips cannot be discharged to the outside of the base, requiring manual cleaning, which increases the workload of the operators. Utility Model Content

[0004] This application provides a horizontal five-axis turning and milling composite machine tool to increase the range of motion of the worktable, increase the flexibility of the worktable, and reduce the workload of the operator.

[0005] The technical solution adopted in this application is as follows:

[0006] A horizontal five-axis turning and milling machine tool includes a base, a wall-type column disposed on and above the base, a worktable slidably connected to the base along a direction close to or away from the wall-type column, and a crossbeam slidably connected to the wall-type column along a direction close to or away from the base. The base is provided with a chip removal groove located below the worktable, the chip removal groove having an open chip removal end. The bottom of the wall-type column is provided with a through-hole into which the worktable extends. The wall-type column and the chip removal end are both located at the same end of the base, so that the through-hole and the openness of the chip removal end together constitute a chip removal port. The bottom of the wall-type column has a first support surface that contacts the base and a second support surface that contacts the base. The first support surface is located obliquely below the through-hole, and the second support surface is located directly below the through-hole.

[0007] By adopting the above technical solution, since the wall-type column in this application is provided with a through-hole for the worktable to extend into, at least a part of the worktable can extend into the through-hole, so that the wall-type column can avoid the worktable, thereby increasing the range of motion of the worktable and increasing its flexibility. At the same time, since the chip discharge end of the chip discharge groove is open, and the wall-type column and the chip discharge end are both located at the same end of the base, the through-hole and the open chip discharge end together constitute the chip discharge port, thereby increasing the volume of the chip discharge port. This allows larger clumps of chips to be discharged to the outside of the base through the chip discharge port under the pushing action of the worktable, avoiding the need for manual cleaning of large clumps of chips, thereby reducing the workload of the workers, improving the user experience, and also improving the automation level of the horizontal five-axis turning and milling composite machine tool.

[0008] Furthermore, since the first support surface is located diagonally below the through opening and the second support surface is located directly below the through opening, and both the first and second support surfaces are in contact with the base, the contact area between the wall column and the base is guaranteed, thereby ensuring the connection stability between the wall column and the base, and thus ensuring the machining accuracy of the horizontal five-axis turning and milling composite machine tool.

[0009] Optionally, the sidewall of the through-hole has an inclination and straight sections located on the upper and lower sides of the inclination, the inclination being inclined from bottom to top toward the outside of the through-hole.

[0010] By adopting the above technical solution, since the through-hole has an inclined section, and the inclined section is inclined from bottom to top toward the outside of the through-hole, the lower width of the through-hole is smaller than the upper width of the through-hole, thereby enabling the second support surface to be located directly below the through-hole.

[0011] Optionally, the horizontal five-axis turning and milling composite machine tool further includes a first drive mechanism, a second drive mechanism, and a protective mechanism. The first drive mechanism is used to drive the worktable to move, the second drive mechanism is used to drive the crossbeam to move, and the protective mechanism includes a support frame disposed on the base, a first protective component connected to the support frame and used to protect the first drive mechanism, and a second protective component connected to the support frame and used to protect the second drive mechanism.

[0012] By adopting the above technical solution, since the first drive mechanism is used to drive the worktable movement and the second drive mechanism is used to drive the crossbeam movement, automatic drive of the worktable and crossbeam can be realized, thereby further improving the automation level of the horizontal five-axis turning and milling composite machine tool. Since both the first and second protective components are located on the support frame, the first and second protective components are integrated using the support frame. This increases the stability of the first and second protective components and facilitates the installation of the protective mechanisms. Furthermore, since the first protective component protects the first drive mechanism and the second protective component protects the second drive mechanism, it prevents debris from contacting the first and second drive mechanisms. This ensures the driving accuracy of the first drive mechanism on the worktable and the driving accuracy of the second drive mechanism on the crossbeam. It also prevents debris from contacting the first and second drive mechanisms, which could cause jamming. This ensures the smoothness of the first drive mechanism's drive on the worktable and the smoothness of the second drive mechanism's drive on the crossbeam.

[0013] Optionally, the first drive mechanism includes a first lead screw pair, the lead screw of the first lead screw pair is rotatably connected to the base, the nut of the first lead screw pair is fixedly connected to the worktable, and the first protective component includes a first telescopic protective cover connected to the worktable and a protective plate connected to the worktable. The first telescopic protective cover is located on the side of the worktable away from the wall-type column, and the protective plate is located on the side of the worktable close to the wall-type column, and the protective plate can pass through the wall-type column through the through-hole.

[0014] By adopting the above technical solution, since the first protective component includes a first telescopic protective cover connected to the worktable and a protective plate connected to the worktable, when the worktable moves, the first telescopic protective cover can telescopically move under the action of the worktable, and the protective plate can slide relative to the through opening under the action of the worktable, so as to achieve real-time protection of the first lead screw pair; at the same time, compared with the solution of telescopic protective covers on both sides of the worktable, it can also reduce the production and manufacturing cost of the horizontal five-axis turning and milling composite machine tool.

[0015] Optionally, the second drive mechanism includes a second lead screw pair, the lead screw of the second lead screw pair is rotatably connected to the wall column, the nut of the second lead screw pair is fixedly connected to the crossbeam, and the second protective assembly includes a second telescopic protective cover connected to the crossbeam, the second telescopic protective cover being located below the crossbeam.

[0016] By adopting the above technical solution, since the second telescopic protective cover is connected to the crossbeam, when the crossbeam moves under the action of the second drive mechanism, the second telescopic protective cover can perform telescopic movement under the action of the crossbeam. Since the second telescopic protective cover is located below the crossbeam, it can provide real-time protection for the part of the second lead screw pair located below the crossbeam, so as to prevent debris from contacting the second lead screw pair. This ensures the driving accuracy of the second drive mechanism on the crossbeam on the one hand, and avoids the second lead screw pair from jamming due to contact between debris and the second lead screw pair on the other hand, thus ensuring the smoothness of the second drive mechanism driving the crossbeam.

[0017] Optionally, the support frame includes a frame fixedly connected to the base and chip guide plates disposed on the frame and located on both sides of the worktable. The chip guide plates are inclined downwards in the direction close to the worktable, and the first telescopic protective cover and the protective plate are both located on the side of the chip guide plates close to the worktable.

[0018] By adopting the above technical solution, since the chip guide plates are located on both sides of the worktable and are inclined downwards in the direction close to the worktable, the chips falling onto the chip guide plates can slide down under the guidance of the chip guide plates. Since the first telescopic protective cover and the protective plate are both located on the side of the chip guide plates close to the worktable, the chips sliding down along the chip guide plates can fall to the top of the first telescopic protective cover and the protective plate, so as to avoid the accumulation of chips on the chip guide plates.

[0019] Optionally, the protective plate has a first side close to the chip guide plate and a second side away from the chip guide plate. The protective plate is inclined downward along the direction from the first side to the second side, and the top view projection of the chip guide plate can coincide with the first side. The top view projection of the second side is located in the chip discharge groove.

[0020] By adopting the above technical solution, since the protective plate is inclined downward along the direction from the first side to the second side, and the top view projection of the chip guide plate can coincide with the first side, and the top view projection of the second side is located in the chip discharge groove, the debris that slides down the protective plate along the chip guide plate can slide down into the chip discharge groove along the inclined direction of the protective plate. On the one hand, this avoids the accumulation of debris on the protective plate, and on the other hand, it allows the debris to collect in the chip discharge groove, so as to facilitate the cleaning of debris.

[0021] Optionally, the top of the first telescopic protective cover has a guide surface, which is inclined downward in a direction away from the chip guide plate.

[0022] By adopting the above technical solution, since the top of the first telescopic protective cover has a guide surface, which is inclined downward in the direction away from the chip guide plate, the debris that slides down the chip guide plate onto the first telescopic protective cover can slide down into the chip discharge groove under the action of the guide surface. On the one hand, this avoids the accumulation of debris on the first telescopic protective cover, and on the other hand, it allows the debris to collect in the chip discharge groove, so as to facilitate the cleaning of debris.

[0023] Optionally, the support frame further includes a fixing plate fixedly connected to the second telescopic protective cover. The fixing plate is fixedly connected to the frame, and the fixing plate extends downward with an edge located on the side of the protective plate away from the first lead screw pair.

[0024] By adopting the above technical solution, since the fixed plate is fixedly connected to the second telescopic protective cover and the frame, the second telescopic protective cover is connected to the frame. Furthermore, since the fixed plate extends downward and has an edge located on the side of the protective plate away from the first lead screw pair, the edge can be used to cover the gap between the protective plate and the fixed plate, thereby increasing the protective effect of the protective plate on the first lead screw pair. This further ensures the driving accuracy of the first drive mechanism on the worktable and the smoothness of the first drive mechanism on the worktable.

[0025] Optionally, the horizontal five-axis turning and milling compound machine tool further includes a chip removal mechanism disposed in the chip removal groove, the chip removal mechanism being used to transport chips or clumps of chips to the outside of the base via the chip removal port.

[0026] By adopting the above technical solution, since the chip removal groove is equipped with a chip removal mechanism, the chips or clumps generated during the machining process of the horizontal five-axis turning and milling composite machine tool can fall onto the chip removal mechanism, thereby enabling the chip removal mechanism to transport the chips or clumps to the outside of the base, so as to realize the automatic cleaning of chips or clumps, and further improve the automation level of the horizontal five-axis turning and milling composite machine tool.

[0027] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0028] 1. The horizontal five-axis turning and milling composite machine tool of this application includes a base, a wall-type column disposed on and above the base, a worktable slidably connected to the base along a direction close to or away from the wall-type column, and a crossbeam slidably connected to the wall-type column along a direction close to or away from the base. The base is provided with a chip removal groove located below the worktable, the chip removal groove having an open chip removal end. The bottom of the wall-type column is provided with a through opening into which the worktable extends, thereby allowing at least a portion of the worktable to extend into the through opening, so that the wall-type column can avoid contact with the worktable. This increases the range of motion of the worktable, thereby enhancing its flexibility. The wall-mounted column and the chip removal end are both located at the same end of the base, so that the through-hole and the open end of the chip removal end together form the chip removal port, which in turn increases the volume of the chip removal port. This allows larger clumps of chips to be discharged through the chip removal port under the pushing action of the worktable, avoiding the need for manual cleaning of large clumps of chips. This reduces the workload of the operators, improves the user experience, and also enhances the automation level of the horizontal five-axis turning and milling composite machine tool.

[0029] 2. The bottom of the wall-type column in this application has a first support surface that contacts the base and a second support surface that contacts the base. The first support surface is located diagonally below the through opening, and the second support surface is located directly below the through opening, thereby ensuring the contact area between the wall-type column and the base, thus ensuring the connection stability between the wall-type column and the base, and further ensuring the machining accuracy of the horizontal five-axis turning and milling composite machine tool.

[0030] 3. The through-hole in this application has an inclined section on its side and straight sections located on the upper and lower sides of the inclined section. The inclined section is inclined from bottom to top toward the outside of the through-hole, so that the lower width of the through-hole is smaller than the upper width of the through-hole, thereby allowing the second support surface to be located directly below the through-hole.

[0045] Reference Figures 1 to 6 A horizontal five-axis turning and milling composite machine tool is disclosed, which includes a base 1, a wall-type column 2 disposed on the base 1 and located above the base 1, a worktable 4 slidably connected to the base 1 in a direction close to or away from the wall-type column 2, and a crossbeam 3 slidably connected to the wall-type column 2 in a direction close to or away from the base 1. The base 1 is provided with a chip removal groove 11 located below the worktable 4. The chip removal groove 11 has an open chip removal end. The bottom of the wall-type column 2 is provided with a through opening 21 for the worktable 4 to extend into. The wall-type column 2 and the chip removal end are both located at the same end of the base 1, so that the through opening 21 and the open chip removal end together constitute a chip removal port.

[0046] It is understood that the base 1 has a length direction and a width direction perpendicular to the length direction. The wall-type column 2 is located at one end of the base 1 in the length direction and is fixedly connected to the top of the base 1. The wall-type column 2 has a length direction, a width direction perpendicular to the length direction, and a thickness direction perpendicular to the length and width directions. The length direction of the wall-type column 2 is set perpendicular to the length direction of the base 1, and the width direction of the wall-type column 2 is set parallel to the width direction of the base 1. The thickness direction of the wall-type column 2 is set parallel to the length direction of the base 1. The worktable 4 is slidably connected to the base 1 along the length direction of the base 1, and the crossbeam 3 is slidably connected to the wall-type column 2 along the length direction of the wall-type column 2. The chip removal groove 11 extends along the length direction of the base 1. The top of the chip removal groove 11 is open so that the chips generated during the processing of the workpiece can fall directly into the chip removal groove 11. The end of the chip removal groove 11 where the wall-type column 2 is located is also open to form a chip removal end. The crossbeam 3 is used to install the processing mechanism for processing the workpiece.

[0047] Since the wall-mounted column 2 in this application is provided with a through opening 21 for the workbench 4 to extend into, at least a portion of the workbench 4 can extend into the through opening 21, so that the wall-mounted column 2 can avoid the workbench 4, thereby increasing the range of motion of the workbench 4 and increasing the flexibility of the workbench 4.

[0048] Meanwhile, since the chip removal end of the chip removal groove 11 is open, and the wall-type column 2 and the chip removal end are both located at the same end of the base 1, the through-hole 21 and the open chip removal end together form a chip removal port, thereby increasing the volume of the chip removal port. This allows larger clumps of chips to be discharged through the chip removal port under the pushing action of the worktable 4, avoiding the need for manual cleaning of larger clumps of chips, thus reducing the workload of the staff, improving the user experience, and also improving the automation level of the horizontal five-axis turning and milling composite machine tool.

[0049] The better one is to refer to Figure 1 and Figure 3 The worktable 4 includes a turntable 41 slidably connected to the base 1 and a plate 42 located above the turntable 41. The turntable 41 can drive the plate 42 to rotate.

[0050] This application does not specifically limit the structure of the through opening 21. Preferably, the through opening 21 is a hole structure that penetrates the wall column 2 in the thickness direction, so as to reduce the manufacturing difficulty of the wall column 2. In other embodiments, the through opening 21 can also be a hole structure that does not penetrate the wall column 2 in the thickness direction, that is, the depth of the through opening 21 is less than the thickness of the wall column 2, and the through opening 21 is located on the side of the wall column 2 closer to the workbench 4.

[0051] In a preferred embodiment, refer to Figure 4 The bottom of the wall column 2 has a first support surface 22 that contacts the base 1 and a second support surface 23 that contacts the base 1. The first support surface 22 is located diagonally below the through opening 21, and the second support surface 23 is located directly below the through opening 21.

[0052] It is understandable that the width of the lower part of the through opening 21 is smaller than the width of the upper part of the through opening 21.

[0053] Since the first support surface 22 is located diagonally below the through opening 21 and the second support surface 23 is located directly below the through opening 21, and both the first support surface 22 and the second support surface 23 are in contact with the base 1, the contact area between the wall column 2 and the base 1 is guaranteed, thereby ensuring the connection stability between the wall column 2 and the base 1, and thus ensuring the machining accuracy of the horizontal five-axis turning and milling composite machine tool.

[0054] Preferably, there are two first support surfaces 22 and two second support surfaces 23, and the two second support surfaces 23 are located between the two first support surfaces 22, so as to further increase the contact area between the wall column 2 and the base 1, thereby further increasing the connection stability between the wall column 2 and the base 1.

[0055] This application does not specifically limit the method in which the width of the lower part of the through opening 21 is smaller than the width of the upper part of the through opening 21. Preferably, refer to Figure 4 The side wall 212 of the through opening 21 has an inclined section 213 and a straight section 214 located on the upper and lower sides of the inclined section 213. The inclined section 213 is inclined from bottom to top toward the outside of the through opening 21.

[0056] It is understood that the through opening 21 has a top wall 211 and side walls 212 located at both ends of the top wall 211. Both side walls 212 have inclined sections 213 and straight sections 214, and each side wall 212 has two straight sections 214, which are located on the upper and lower sides of the inclined section 213 respectively.

[0057] Since the through opening 21 has an inclined section 213, and the inclined section 213 is inclined from bottom to top toward the outside of the through opening 21, the lower width of the through opening 21 is smaller than the upper width of the through opening 21, thereby enabling the second support surface 23 to be located directly below the through opening 21.

[0058] In other implementation examples, both sidewalls 212 of the through opening 21 can also be arc-shaped walls, so that the lower width of the through opening 21 is smaller than the upper width of the through opening 21.

[0059] In a preferred embodiment, refer to Figures 1 to 3The horizontal five-axis turning and milling composite machine tool also includes a first drive mechanism, a second drive mechanism, and a protective mechanism. The first drive mechanism is used to drive the worktable 4 to move, the second drive mechanism is used to drive the crossbeam 3 to move, and the protective mechanism includes a support frame 71 on the base 1, a first protective component 72 connected to the support frame 71 and used to protect the first drive mechanism, and a second protective component 73 connected to the support frame 71 and used to protect the second drive mechanism.

[0060] Since the first drive mechanism is used to drive the worktable 4 to move and the second drive mechanism is used to drive the crossbeam 3 to move, the automatic drive of the worktable 4 and the crossbeam 3 can be realized, thereby further improving the automation level of the horizontal five-axis turning and milling composite machine tool. Since the first protective component 72 and the second protective component 73 are both located on the support frame 71, the first protective component 72 and the second protective component 73 can be connected as one unit by the support frame 71. On the one hand, the stability of the first protective component 72 and the second protective component 73 can be increased, and on the other hand, the installation of the protective mechanism can be facilitated.

[0061] Furthermore, since the first protective component 72 is used to protect the first drive mechanism and the second protective component 73 is used to protect the second drive mechanism, it is possible to prevent debris from coming into contact with the first and second drive mechanisms. On the one hand, this ensures the driving accuracy of the first drive mechanism on the worktable 4 and the driving accuracy of the second drive mechanism on the crossbeam 3. On the other hand, it also prevents debris from coming into contact with the first and second drive mechanisms, which could cause the first and second drive mechanisms to jam. This ensures the smoothness of the first drive mechanism driving the worktable 4 and the smoothness of the second drive mechanism driving the crossbeam 3.

[0062] The better one is to refer to Figure 3 The first drive mechanism and the second drive mechanism are each provided in two sets. The two sets of first drive mechanisms are located on both sides of the worktable 4 to ensure the smooth movement of the worktable 4 and the driving accuracy of the worktable 4. The two sets of second drive mechanisms are located at both ends of the crossbeam 3 to ensure the smooth movement of the crossbeam 3 and the driving accuracy of the crossbeam 3. The first protective component 72 and the second protective component 73 are each provided in two sets. The two sets of first protective components 72 are respectively provided for the two sets of first drive mechanisms, and the two sets of second protective components 73 are respectively provided for the two sets of second drive mechanisms.

[0063] This application does not specifically limit the structure of the first driving mechanism and the first protective component 72; preferably, refer to... Figures 1 to 3The first drive mechanism includes a first lead screw pair 51, the lead screw of the first lead screw pair 51 is rotatably connected to the base 1, and the nut of the first lead screw pair 51 is fixedly connected to the workbench 4. The first protective component 72 includes a first telescopic protective cover 721 connected to the workbench 4 and a protective plate 722 connected to the workbench 4. The first telescopic protective cover 721 is located on the side of the workbench 4 away from the wall column 2, and the protective plate 722 is located on the side of the workbench 4 close to the wall column 2. The protective plate 722 can pass through the wall column 2 through the through opening 21.

[0064] Understandably, the first lead screw assembly 51 has a lead screw and a nut threaded to the lead screw. The lead screw of the first lead screw assembly 51 is arranged parallel to the length direction of the base 1, and the nut of the first lead screw assembly 51 is fixedly connected to the turntable 41. The first telescopic protective cover 721 and the protective plate 722 are located between the platform 42 and the lead screw of the first lead screw assembly 51. The telescopic direction of the first telescopic protective cover 721 is arranged parallel to the length direction of the base 1, and the innermost section of the first telescopic protective cover 721 is fixedly connected to the turntable 41 of the workbench 4, and the outermost section of the first telescopic protective cover 721 is fixedly connected to the support frame 71. The protective plate 722 extends along the length direction of the base 1, and one end of the protective plate 722 is fixedly connected to the turntable 41.

[0065] Since the first protective component 72 includes a first telescopic protective cover 721 connected to the worktable 4 and a protective plate 722 connected to the worktable 4, when the worktable 4 moves, the first telescopic protective cover 721 can telescopically move under the action of the worktable 4, and the protective plate 722 can slide relative to the through opening 21 under the action of the worktable 4, so as to achieve real-time protection of the first lead screw pair 51; at the same time, compared with the solution of telescopic protective covers on both sides of the worktable 4, it can also reduce the production cost of the horizontal five-axis turning and milling composite machine tool.

[0066] The better one is to refer to Figure 3 The first drive mechanism also includes a first servo motor 52 fixedly connected to the base 1. The output shaft of the first servo motor 52 is coaxially fixedly connected to the lead screw of the first lead screw pair 51, so as to drive the lead screw of the first lead screw pair 51 to rotate by means of the first servo motor 52.

[0067] This application does not provide a detailed description of the structure of the first telescopic protective cover 721, which can be found in existing technologies.

[0068] In other embodiments, the first drive mechanism may also be a cylinder, hydraulic cylinder, or electric actuator, or other structure capable of driving the worktable 4 to move along the length of the base 1.

[0069] In other embodiments, the first protective structure may also consist of two sets of first telescopic protective covers 721.

[0070] This application does not specifically limit the structure of the second drive mechanism and the second protective component 73. Preferably, refer to Figures 1 to 3 The second drive mechanism includes a second lead screw pair 61, the lead screw of the second lead screw pair 61 is rotatably connected to the wall column 2, and the nut of the second lead screw pair 61 is fixedly connected to the crossbeam 3. The second protective assembly 73 includes a second telescopic protective cover 731 connected to the crossbeam 3, and the second telescopic protective cover 731 is located below the crossbeam 3.

[0071] Understandably, the second lead screw assembly 61 has a lead screw and a nut threaded to the lead screw, and the lead screw of the second lead screw assembly 61 is arranged parallel to the length direction of the wall column 2; the second telescopic protective cover 731 is located between the workbench 4 and the lead screw of the second lead screw assembly 61, the telescopic direction of the second telescopic protective cover 731 is arranged parallel to the length direction of the wall column 2, and the innermost section of the second telescopic protective cover 731 is fixedly connected to the bottom of the crossbeam 3, and the outermost section of the second telescopic protective cover 731 is fixedly connected to the support frame 71.

[0072] Since the second telescopic protective cover 731 is connected to the crossbeam 3, when the crossbeam 3 moves under the action of the second drive mechanism, the second telescopic protective cover 731 can telescopically move under the action of the crossbeam 3. Since the second telescopic protective cover 731 is located below the crossbeam 3, it can provide real-time protection for the part of the second lead screw pair 61 located below the crossbeam 3, so as to avoid the possibility of debris contacting the second lead screw pair 61. This ensures the driving accuracy of the second drive mechanism on the crossbeam 3 on the one hand, and avoids the second lead screw pair 61 from getting stuck due to contact between debris and the second lead screw pair 61 on the other hand, thus ensuring the smoothness of the second drive mechanism driving the crossbeam 3.

[0073] Preferably, the second drive mechanism also includes a second servo motor fixedly connected to the wall-mounted column 2. The output shaft of the second servo motor is coaxially fixedly connected to the lead screw of the second lead screw pair 61, so as to drive the lead screw of the second lead screw pair 61 to rotate using the second servo motor.

[0074] Furthermore, a second servo motor is located at the top of the second lead screw pair 61, so that the crossbeam 3 can move to the bottom of the wall column 2.

[0075] This application does not provide a detailed description of the structure of the second telescopic protective cover 731, which can be found in existing technologies.

[0076] In other embodiments, the second drive mechanism may also be a cylinder, hydraulic cylinder, or electric actuator, or other structure capable of driving the crossbeam 3 to move along the length of the wall-type column 2.

[0077] In other embodiments, the second protective structure also includes an upper guard plate, which is fixedly connected to the top of the crossbeam 3 to provide all-round protection for the lead screw of the second lead screw pair 61.

[0078] This application does not specifically limit the structure of the support frame 71; preferably, refer to... Figure 1 and Figure 2 The support frame 71 includes a frame 711 fixedly connected to the base 1 and chip guide plates 712 disposed on the frame 711 and located on both sides of the worktable 4. The chip guide plates 712 are inclined downward along the direction close to the worktable 4. The first telescopic protective cover 721 and the protective plate 722 are both located on the side of the chip guide plate 712 close to the worktable 4.

[0079] It is understandable that there are two chip guide plates 712, which correspond to the two sets of first drive mechanisms, and the two chip guide plates 712 are inclined downwards in the direction of mutual approach.

[0080] Since the chip guide plate 712 is located on both sides of the worktable 4 and is inclined downwards in the direction close to the worktable 4, the chips falling onto the chip guide plate 712 can slide down under the guidance of the chip guide plate 712. Since the first telescopic protective cover 721 and the protective plate 722 are both located on the side of the chip guide plate 712 close to the worktable 4, the chips sliding down along the chip guide plate 712 can fall to the top of the first telescopic protective cover 721 and the protective plate 722, so as to avoid the accumulation of chips on the chip guide plate 712.

[0081] Furthermore, refer to Figure 1 and Figure 2 The protective plate 722 has a first side close to the chip guide plate 712 and a second side away from the chip guide plate 712. The protective plate 722 is inclined downward along the direction from the first side to the second side, and the top view projection of the chip guide plate 712 can coincide with the first side. The top view projection of the second side is located in the chip discharge groove 11. This allows the debris that slides down the chip guide plate 712 onto the protective plate 722 to slide down the inclined direction of the protective plate 722 into the chip discharge groove 11. On the one hand, this avoids the accumulation of debris on the protective plate 722, and on the other hand, it allows the debris to collect in the chip discharge groove 11, so as to facilitate the cleaning of debris.

[0082] Furthermore, refer to Figure 1 and Figure 2The top of the first telescopic protective cover 721 has a guide surface, which is inclined downward in a direction away from the chip guide plate 712. This allows the debris that slides down the chip guide plate 712 onto the first telescopic protective cover 721 to slide into the chip discharge groove 11 under the action of the guide surface. This avoids the accumulation of debris on the first telescopic protective cover 721 and allows the debris to collect in the chip discharge groove 11, thus facilitating the cleaning of the debris.

[0083] Furthermore, refer to Figure 2 and Figure 6 The support frame 71 also includes a fixing plate 713 fixedly connected to the second telescopic protective cover 731. The fixing plate 713 is fixedly connected to the frame 711, and the fixing plate 713 extends downward with an edge 714 located on the side of the protective plate 722 away from the first lead screw pair 51.

[0084] Understandably, the fixing plate 713 is fixedly connected to the outermost section of the second telescopic protective cover 731.

[0085] Since the fixing plate 713 is fixedly connected to the second telescopic protective cover 731 and the fixing plate 713 is fixedly connected to the frame 711, the second telescopic protective cover 731 is thus connected to the frame 711.

[0086] Furthermore, since the fixed plate 713 extends downward and is provided with an edge 714, which is located on the side of the protective plate 722 away from the first lead screw pair 51, the edge 714 can be used to cover the gap between the protective plate 722 and the fixed plate 713, thereby increasing the protective effect of the protective plate 722 on the first lead screw pair 51. This further ensures the driving accuracy of the first drive mechanism on the worktable 4 and the smoothness of the first drive mechanism on the worktable 4.

[0087] In a preferred embodiment, refer to Figure 1 and Figure 2 The horizontal five-axis turning and milling composite machine tool also includes a chip removal mechanism 8 located in the chip removal groove 11, so that the chips or clumps generated during the processing of the workpiece fall directly onto the chip removal mechanism 8, thereby allowing the chip removal mechanism 8 to directly transport the chips or clumps to the outside of the base 1 through the chip removal port, so as to achieve the effect of real-time cleaning of chips or clumps.

[0088] This application does not specifically limit the structure of the chip removal mechanism 8. The chip removal mechanism 8 can be a belt conveyor or a screw conveyor installed in the chip removal trough 11. When the chip removal mechanism 8 is a screw conveyor, the cylinder of the screw conveyor is arranged parallel to the length direction of the base 1, and the top of the cylinder is open.
