Description

Technical Field

[0001] The present application relates to the field of aviation processing equipment, and in particular to a titanium alloy flap slide rail processing machine tool. Background Art

[0002] Flaps are movable winglets installed at the rear of the wings of large aircraft, which are used to adjust the aerodynamic performance of the wings and control the flight status of large aircraft. When the large aircraft takes off, the descent of the flaps forms a downward curved arc at the rear end of the wing, which increases the upward lift of the aircraft; when the large aircraft lands, the rise of the flaps increases the airflow resistance of the wing, causing the speed of the aircraft to drop rapidly; during the flight of the large aircraft, the flaps can also guide and adjust the air flow state on both sides of the wing to ensure the stability of the aircraft's flight. They are important components for controlling the flight status of large aircraft.

[0003] The flaps of an aircraft usually slide along the flap rails set under the wing under the push of a hydraulic mechanism. The flap rails not only need to ensure the stability of the flap sliding, but also need to reduce the disturbance to the airflow during the flight of the aircraft and reduce the flight resistance. The flap rails are usually made of titanium alloy. Titanium alloy materials have high hardness and poor machinability. When processing the flap rails, it is usually necessary to apply a greater cutting feed force. In order to reduce the airflow resistance of the flap rails, the flap rails are required to have a higher surface quality, which increases the difficulty of processing the flap rails.

[0004] The ram of the existing machine tool is usually slidably mounted on the slide plate, the slide plate is slidably mounted on the crossbeam, and the crossbeam is slidably mounted on the bed. The Z-direction sliding of the ram on the slider, the X-direction sliding of the slide plate on the crossbeam, and the Y-direction sliding of the crossbeam on the bed form the free sliding of the spindle head installed on the ram in three-dimensional space. This sliding connection method causes more sliding connection structures of the spindle head, and the cantilever of the spindle head is usually longer, and the processing rigidity of the spindle head is poor. When machining the aircraft flap rail, it is necessary to perform a large amount of cutting on the high-hardness titanium alloy material, which easily causes the position deformation of the spindle head under large cutting stress, affecting the machining accuracy of the flap rail. The sliding parts of the existing CNC machine tools are mostly connected by a single linear rail or hard rail. The position stability of the sliding parts under high cutting stress is poor, and the wear between the slide rail and the slider is also large, making it difficult to maintain the machining accuracy of the machine tool. Summary of the invention

[0006] The titanium alloy flap slide rail processing machine tool provided in this application adopts the following technical solution: A titanium alloy flap slide processing machine tool comprises a bed, a worktable, a crossbeam frame, a box-in-box slide plate and a ram, wherein the worktable and the crossbeam frame are respectively arranged on opposite sides of the bed, and the worktable is installed on one side of the bed and can slide on the bed in the X direction, the crossbeam frame is fixed on the other side of the bed, the box-in-box slide plate is arranged on the inner side of the crossbeam frame and can slide on the inner side of the crossbeam frame in the Y direction, the ram is arranged in the box-in-box slide plate and can slide in the box-in-box slide plate in the Z direction, so that the workpiece installed on the worktable can be cut by using the spindle head installed on the ram.

[0007] By adopting the above technical solution, the position stability between the crossbeam frame and the workbench can be improved by using the setting that the workbench and the crossbeam frame are set on the same integral bed. By using the setting that the workbench is slidably mounted on the bed in the X direction and the crossbeam frame is fixed on the bed, the number of sliding connections between the workbench and the spindle head mounted on the crossbeam frame can be limited, the accumulation of spindle head motion errors and the increase of stress arms can be reduced, and the processing rigidity of the spindle head can be improved. By using the setting that the box-in-box slide is installed on the inner side of the crossbeam frame and the ram is installed in the box-in-box slide, the stability of the sliding position of the ram and the box-in-box slide can be improved, and the positioning accuracy of the spindle head in the Y and Z directions can be ensured.

[0008] In a specific feasible implementation scheme, the crossbeam frame includes a crossbeam and two columns, the columns are fixed to the bed and are respectively supported under the two sides of the crossbeam, the opposite sides of the columns are provided with Y-axis driving screws and at least two Y-axis slide rails, the two sides of the box-in-box slide plate are respectively fixed on the sliders of the Y-axis slide rails, and can slide in the Y direction on the columns under the drive of the Y-axis driving screw.

[0009] By adopting the above technical solution, the two sides of the box-in-box slide are respectively installed on the two side columns through the Y-direction slide rails, so that the box-in-box slide can be restricted to slide between the two columns, thereby improving the position stability of the box-in-box slide when sliding. By arranging two Y-direction slide rails and a Y-direction drive screw on each side of the box-in-box slide, a stable support can be formed for the box-in-box slide around the spindle head, and symmetrical Y-direction driving force can be provided on both sides of the box-in-box slide, thereby further improving the position stability of the box-in-box slide and the smoothness of Y-direction sliding.

[0011] By adopting the above technical solution, the left and right sides of the slide are respectively slidably connected with the first slide and the second slide through the Z-direction slide rail, and the top surface is slidably connected with the first support plate through the Z-direction hard rail. The position of the slide can be restricted from three sides of the slide, thereby ensuring the stability of the sliding position of the slide in the box-in-box slide and the supporting force on the side of the slide in different directions.

[0012] In a specific possible implementation scheme, a spindle hole is provided on the ram, the spindle hole is arranged in a lower middle position of the ram, and the spindle head is installed in the spindle hole.

[0013] By adopting the above technical solution, the gravity stability of the ram can be improved by setting the spindle hole at the lower middle part of the ram. The Z-direction hard rail set on the top surface of the ram can effectively resist the cutting stress when the spindle head set at the bottom of the ram processes the flap slide rail, thereby improving the processing rigidity of the spindle head.

[0015] By adopting the above technical solution, with the workbench mounting portion extending along the X direction and the crossbeam frame mounting portion being integrally connected to the middle part of the workbench mounting portion on one side in the Z direction, an overall inverted T-shaped horizontal bed structure can be formed, which provides a stable supporting force for the workbench and the crossbeam frame relatively installed on the workbench mounting portion and the crossbeam frame mounting portion, and is beneficial to improving the positional stability between the two.

[0016] In a specific feasible implementation scheme, X-axis linear rails are arranged on both sides of the top surface of the workbench mounting portion, the workbench is fixedly connected to the slider of the X-axis linear rails, an X-axis driving screw is arranged between the workbench mounting portion and the workbench, X-axis hard rails are arranged on the top of the two side surfaces of the workbench mounting portion, support wings are arranged on the opposite sides of the workbench, a hard rail groove is arranged on the side of the support wing opposite to the X-axis hard rail, and an X-axis sliding bar is arranged in the hard rail groove.

[0017] By adopting the above technical solution, the X-direction linear rails arranged on both sides of the top surface of the workbench installation part and the X-direction hard rails on both sides of the side surface can form lateral support for the workbench in different directions, further improve the lateral bearing capacity of the workbench when sliding along the X-direction, and ensure the position stability of the workbench when sliding in the X-direction. The support wings arranged on both sides of the workbench can form a supporting force on the side of the workbench, and improve the position stability of the flap slide rails installed on the workbench during processing.

[0018] In a specific possible implementation scheme, the X-axis hard rail on the side of the workbench mounting portion adjacent to the crossbeam frame (3) is a steel-embedded guide rail.

[0019] By adopting the above technical solution, using the steel-embedded guide rail arranged on the side of the workbench mounting portion adjacent to the crossbeam frame, the rigidity and wear resistance of the hard rail on this side can be improved, and the cutting stress transmitted to the workbench when the spindle head performs cutting processing on the flap slide rail clamped on the workbench can be better resisted, which is beneficial to ensuring the position stability of the flap slide rail under large cutting stress conditions and improving the processing accuracy of the flap slide rail.

[0020] In a specific possible implementation scheme, a support wing bottom plate is provided on the support wing of the workbench on the side away from the crossbeam frame, and the support wing bottom plate is fixed on the support wing and slidably connected to the bottom surface of the X-axis hard rail.

[0021] By adopting the above technical solution, by utilizing the support wing bottom plate arranged on the support wing and connected to the bottom slide rail of the X-axis hard rail, another sliding surface for sliding support of the workbench can be formed, further ensuring the position stability of the workbench under large cutting stress.

[0022] In a specific possible implementation manner, a chip removal groove is provided on the bed between the workbench mounting portion and the beam frame mounting portion, and a chip removal mechanism is provided in the chip removal groove.

[0023] By adopting the above technical scheme, utilizing the chip groove arranged between the worktable mounting part and the crossbeam mounting part on the bed, and the chip removal mechanism arranged in the chip groove, the chips formed by the spindle head performing cutting processing on the flap slide rail can be discharged in time, preventing the chips from scratching the surface of the flap slide rail, thereby ensuring the surface quality of the flap slide rail cutting processing.

[0024] In a specific feasible implementation scheme, telescopic chip guards are provided at both ends of the workbench mounting portion, one end of the telescopic chip guards is fixed on the workbench mounting portion, and the other end is fixedly connected to the workbench; a lifting chip guard curtain is provided on the side of the crossbeam frame adjacent to the workbench, and one end of the slide passes through the lifting chip guard curtain and is connected to the lifting chip guard curtain.

[0025] By adopting the above technical solution, the telescopic chip guards arranged on both sides of the workbench can protect the sliding connection structures such as the X-direction slide rail and the X-direction drive screw, prevent the cutting chips from causing wear of the X-direction sliding connection structure, and ensure the X-direction sliding accuracy of the workbench. The lifting chip guard curtain installed on the side of the beam frame adjacent to the workbench can block the cutting chips from entering the inner side of the beam frame, preventing the cutting chips from damaging the Y-direction sliding connection structure and the Z-direction sliding connection structure on the inner side of the beam frame, affecting the motion accuracy of the spindle head in the Y-direction motion and the Z-direction motion.

By arranging the workbench and the crossbeam frame on the same bed, the workbench slides in the X direction on the bed, and the crossbeam frame is fixed on the bed, it is possible to form a one-dimensional linear motion of the workbench on the bed and a two-dimensional motion of the spindle head on the bed, respectively, thereby reducing the stress arm of the cutting stress borne by the sliding connection structure of the spindle head during cutting, which is beneficial to improving the structural rigidity of the spindle head when cutting the aircraft flap slide rail and the position stability when sliding on the crossbeam frame; 2. By installing the box-in-box slide plate on the inner side of the crossbeam frame and the ram in the box-in-box slide plate, the crossbeam frame can be used to limit the sliding position of the two sides of the box-in-box slide plate, and the box-in-box slide plate can be used to limit the sliding position of the ram in multiple directions around the ram, which can improve the position stability of the box-in-box slide plate in the Y direction and the position stability of the ram in the Z direction, increase the cutting stress that the spindle head can withstand, and improve the processing efficiency and processing accuracy when processing the flap slide rail; 3. By setting Z-direction linear rails on the upper and lower sides of the left and right sides of the ram, and setting Z-direction hard rails on the top surface of the ram, multiple sides of the ram can be supported at the same time, effectively improving the lateral bearing capacity of the ram when it slides in the Z direction in the box-in-box slide, improving the position stability of the ram under high cutting stress, and ensuring the position accuracy of the spindle head; 4. By arranging X-axis linear rails on both sides of the top surface of the workbench mounting part and arranging X-axis hard rails on both sides of the workbench mounting part, lateral support can be formed for the workbench in different directions, further improving the lateral bearing capacity of the workbench when sliding along the X-axis, and improving the position stability of the workbench and the aircraft flap slide rail clamped on the workbench when sliding in the X-axis under large cutting stress, thereby ensuring the cutting amount and processing accuracy when the spindle head processes the flap slide rail.

[0034] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In this specification, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0037] An embodiment of the titanium alloy flap slide rail processing machine tool of the present application is as follows Figure 1 and Figure 2 As shown, it includes a bed 1, a workbench 2, a crossbeam frame 3, a box-in-box slide 4 and a ram 5. The bed 1 is a mounting base usually cast by cast iron material, and other structures of the machine tool are usually arranged on the bed 1 to form the installation positioning of different structures and the positional relationship between them.

[0038] The workbench 2 is a clamping platform for the workpiece to be processed, and a plurality of clamping grooves and clamping holes for clamping the workpiece to be processed are usually provided on the workbench 2. The workpiece to be processed can be clamped directly on the workbench 2, or it can be clamped on an auxiliary clamping block, and then the auxiliary clamping block is fixed on the workbench 2. A horizontally arranged sliding connection structure is provided on one side of the bed 1, and the workbench 2 is installed on the sliding connection structure, and can slide on the bed 1 along the X direction through the sliding connection structure.

[0039] The crossbeam frame 3 is a mounting and positioning structure for the box-in-box slide plate 4, and is usually formed by connecting casting materials to ensure the structural strength of the crossbeam frame 3. The crossbeam frame 3 is installed and fixed on the other side of the bed 1, and is arranged opposite to the workbench 2.

[0040] The box-in-box skateboard 4 is a box-shaped skateboard installed and connected by casting materials. A vertically extending sliding connection structure is arranged on the two side frames of the cross beam frame 3. The box-in-box skateboard 4 is arranged in the skateboard installation space inside the cross beam frame 3, and the two sides are respectively installed on the sliding connection structures on both sides of the cross beam frame 3. It can slide along the Y direction on the cross beam frame 3 through the sliding connection structure.

[0041] The ram 5 is a barrel-shaped structure for mounting a spindle head 6 for cutting a workpiece to be processed. A horizontally extending ram mounting space is provided in the box-in-box slide 4, and a sliding connection structure is provided on the side wall of the box-in-box slide 4 around the mounting space. The ram 5 is mounted on the sliding connection structure on the side wall of the box-in-box slide 4 and can slide in the ram mounting space in the box-in-box slide 4 along the Z direction perpendicular to the X direction.

[0042] When machining the flap rail of an aircraft, an auxiliary clamping block is usually fixed on the workbench 2 along the X direction, and the flap rail is clamped on the auxiliary clamping block on the side facing the ram 5. A spindle head 6 for cutting the flap rail is installed on the ram 5, and the spindle head 6 and the flap rail are freely moved in three-dimensional space by using the X-direction movement of the workbench 2 on the bed, the Y-direction movement of the box-in-box slide 4 in the crossbeam frame 3, and the Z-direction movement of the ram 5 in the box-in-box slide 4, so as to cut the flap rail.

[0043] Since the workbench 2 only slides along the X-direction on the bed 1, it is easier to strengthen the workbench 2 laterally to ensure the lateral bearing capacity of the workbench 2 when it slides. The crossbeam frame 3 is fixed on the bed 1, the box-in-box slide plate 4 slides in the Y-direction inside the crossbeam frame 3, and the ram 5 slides in the Z-direction inside the box-in-box slide plate 4. Compared with the traditional processing method of three-dimensional movement of the processing head, it not only reduces the sliding dimension of the spindle head 6 fixed on the slide plate 5, but also improves the rigidity of the spindle head 6 when it moves in two dimensions, can form greater processing rigidity for the workpiece to be processed, can adapt to large-volume cutting of the flap slide rail of titanium alloy material, especially rough processing, improve the processing accuracy of the flap slide rail, and reduce the wear of the machine tool during processing.

[0044] Since the flap slide rail is clamped on the vertical clamping surface on the auxiliary clamping block facing the slide 5, the spindle head 6 is horizontally arranged to perform horizontal processing on the flap slide rail, which is beneficial for the cutting chips formed during processing to separate from the flap slide rail and slide downward, reducing the pulling and scratching of the cutting chips on the surface of the flap slide rail, which is beneficial to ensuring the surface quality of the flap slide rail cutting processing.

[0045] In some embodiments of the titanium alloy flap slide rail processing machine tool of the present application, as Figure 2 and Figure 3 As shown, the crossbeam frame 3 includes a crossbeam 31 and two columns 32. The lower ends of the two columns 32 are fixed on the bed 1 and are arranged opposite to each other on the bed 1. Both sides of the crossbeam 31 are respectively fixed to the tops of the two columns 32, and a rectangular slide installation space is formed below the crossbeam 31 and between the two columns 32.

[0046] On the inner side of each column 32, that is, on both sides of the Z direction on one side facing the slide installation space, a Y-direction slide rail 322 is respectively arranged. The two Y-direction slide rails 322 on each column 32 are arranged parallel to the Y direction on the inner side of the column 32. The box-in-box slide plate 4 is arranged in the slide installation space, and the slide installation space inside it is arranged horizontally. The two sides of the box-in-box slide plate 4 are respectively fixed on the sliders of the two Y-direction slide rails 322 on the corresponding side column 32. Usually, multiple sliders can be arranged on one Y-direction slide rail 322, such as three sliders are arranged on each Y-direction slide rail 322, and the box-in-box slide plate 4 is fixedly connected to the three sliders on each Y-direction slide rail 322 at the same time, so as to improve the lateral bearing capacity of the box-in-box slide plate 4 when sliding on the Y-direction slide rail 322.

[0047] In the middle of the inner side of each column 32, a Y-axis driving screw 321 is arranged between the two Y-axis slide rails 322. The Y-axis driving screw 321 is arranged parallel to the Y-axis slide rail 322. One end of the Y-axis driving screw 321 passes through the crossbeam 31 and is connected to the Y-axis driving motor. The two sides of the box-in-box slide 4 are respectively fixedly connected to the screw nuts of a Y-axis driving screw 321. By controlling the rotation of the Y-axis driving motor, the Y-axis driving screw 321 can be driven to rotate, thereby driving the box-in-box slide 4 to slide in the Y direction on the column 32 along the Y-axis slide rail 322. By fixing the two sides of the box-in-box slide 4 in the Z direction on the sliders of a Y-axis slide rail 322, the lateral bearing capacity of the box-in-box slide 4 when sliding in the Y direction is effectively improved.

[0048] In a preferred embodiment of the titanium alloy flap slide rail processing machine tool of the present application, as Figure 3 and Figure 4 As shown, the box-in-box slide plate 4 includes a first slide plate 41, a second slide plate 42, a first support plate 43, and a second support plate 44. The first slide plate 41 and the second slide plate 42 are arranged in parallel in the vertical direction, that is, in the Y direction; the first support plate 43 and the second support plate 44 are horizontally connected to the upper and lower sides of the first slide plate 41 and the second slide plate 42, respectively, and a ram installation space for installing the ram 5 is formed inside the first slide plate 41, the second slide plate 42, the first support plate 43, and the second support plate 44.

[0049] The ram 5 is installed in the ram installation space, and a Z-direction linear rail 51 is provided on both sides of the ram 5 on the Y direction opposite to the first slide plate 41 and the second slide plate 42, that is, at the four corners of the ram 5. A plurality of sliders are provided on each Z-direction linear rail 51, such as three sliders, and the three sliders on each Z-direction linear rail 51 are fixedly connected to the first slide plate 41 or the second slide plate 42 on the opposite side, so that the ram 5 can slide in the Z direction in the ram installation space. The four Z-direction linear rails 51 respectively provided at the four corners of the ram 5 can form a stable support for the ram 5, and improve the lateral bearing capacity of the ram 5 when sliding in the Z direction.

[0050] A Z-direction hard rail 52 extending in the Z-direction is provided in the middle of the top surface of the ram 5, and the Z-direction hard rail 52 is integrally formed on the ram 5. A hard rail slide groove 431 is provided at a position corresponding to the Z-direction hard rail 52 on the first support plate 43, and the bottom surface of the hard rail slide groove 431 is processed to form a sliding surface adapted to the top surface of the Z-direction hard rail 52; Z-direction slide bars 432 are provided on both sides of the hard rail slide groove 431, and the Z-direction slide bars 432 are usually formed by processing high-hardness alloy steel. The two sides of the hard rail slide groove 431 are slidably connected with the Z-direction hard rail 52 through the Z-direction slide bars 432, which can better limit the sliding position of the Z-direction hard rail 52 in the hard rail slide groove 431, and further improve the position accuracy and lateral bearing capacity of the Z-direction sliding of the ram 5.

[0051] A Z-direction drive screw 421 is arranged between two Z-direction linear rails 51 in the middle of the second slide plate 42, and a Z-direction drive motor is arranged at one end of the Z-direction drive screw 421 away from the workbench 2, and the output shaft of the Z-direction drive motor is connected to the Z-direction drive screw 421 through a reducer, and the screw nut of the Z-direction drive screw 421 is fixedly connected to the ram 5. By controlling the rotation of the Z-direction drive motor, the Z-direction drive screw 421 can be driven to rotate, thereby driving the ram 5 to slide along the Z-direction linear rail 51 and the Z-direction hard rail 52, forming the Z-direction movement of the spindle head 6.

The spindle head 6 is installed and fixed in the spindle hole 53, and the end of the spindle head 6 extends out of the spindle hole 53, so that the processing tool installed on the spindle head 6 faces the workpiece to be processed, such as the direction of the flap slide rail.

[0053] The titanium alloy flap slide rail processing machine tool of the present application may also be provided with a tool magazine, which is installed on the bed 1 or other machine tool structures connected to the bed 1. The tool magazine can be used to conveniently replace the processing tools installed on the spindle head 6, and different tools can be used to perform different processing operations on the flap slide rail, thereby improving the processing efficiency of the flap slide rail.

[0054] In some embodiments of the titanium alloy flap slide rail processing machine tool of the present application, as Figure 2 As shown, the bed 1 includes an integrally connected workbench mounting portion 11 and a beam mounting portion 12. The length direction of the workbench mounting portion 11 is arranged along the X direction, and the beam mounting portion 12 is integrally connected to one side of the middle part of the workbench mounting portion 11, so that the projection of the bed 1 on the horizontal plane is "T" shaped.

[0055] The workbench mounting portion 11 is provided with a slide rail extending in the X direction, that is, extending in the length direction of the workbench mounting portion 11. The workbench 2 is slidably mounted on the slide rail on the workbench mounting portion 11 and can slide along the slide rail in the X direction on the workbench mounting portion 11. The crossbeam frame 3 is fixed on the crossbeam frame mounting portion 12. Usually, two columns 32 of the crossbeam frame 3 are respectively fixed on both sides of the crossbeam frame mounting portion 12 in the X direction, so that the crossbeam 31 of the crossbeam frame 3 is parallel to the moving direction of the workbench 2, and the two are arranged opposite to each other in the Z direction.

[0056] In a preferred embodiment of the titanium alloy flap slide rail processing machine tool of the present application, as Figure 2 , Figure 5 and Figure 6 As shown, an X-direction linear rail 111 is provided on both sides of the top surface of the workbench mounting portion 11 in the Y direction, and the two X-direction linear rails 111 are provided in parallel on the workbench mounting portion 11. A plurality of sliders, such as three sliders, are provided on each X-direction linear rail 111, and the two sides of the workbench 2 in the Y direction are fixedly connected to the three sliders on an X-direction linear rail 111, respectively, to ensure the lateral bearing capacity of the workbench 2 when sliding on the workbench mounting portion 11.

[0057] An X-direction drive screw 112 is arranged between two X-direction linear rails 111 on the workbench mounting portion 11. The X-direction drive screw 112 is arranged parallel to the two X-direction linear rails 111, and the workbench 2 is fixedly connected to the screw nut of the X-direction drive screw 112.

The output shaft of the X-direction drive motor is connected to the X-direction drive screw 112 through a reducer. By controlling the rotation of the X-direction drive motor, the X-direction drive screw 112 can be driven to rotate, thereby driving the workbench 2 to slide along the X-direction linear rails 111 in the X-direction direction.

[0058] X-direction hard rails 113 are provided on both sides of the workbench mounting portion 11 in the width direction, that is, on both sides of the Y direction. The X-direction hard rails 113 are integrally formed at the upper edge of the side of the workbench mounting portion 11. Support wings 21 are provided on both sides of the Y direction on the workbench 2. The support wings 21 extend downward from the side of the workbench 2 to cover the height of the X-direction hard rails 113. In this embodiment, two support wings 21 are provided on the same side of the workbench 2, and the two support wings 21 are respectively provided on both sides of the length direction of the workbench 2. Of course, multiple support wings 21 can be provided on the same side of the workbench 2, or a longer support wing 21 that can cover most of the length of the workbench 2 can be provided.

[0059] A hard rail groove 211 is provided on the inner side of the support wing 21, that is, on the side adjacent to the X-direction linear rail 111, and the X-direction hard rail 113 is located in the hard rail groove 211. An X-direction slide bar 212 is provided on the bottom surface of the hard rail groove 211, and the support wing 21 contacts the outer side of the X-direction hard rail 113 through the X-direction slide bar 212, and slides in the X direction along the X-direction hard rail 113. The provision of the support wing 21 increases the lateral support force of the workbench mounting portion 11 on the workbench 2, and effectively improves the position stability and lateral bearing capacity of the workbench 2 when sliding laterally.

[0060] As a specific implementation of the titanium alloy flap slide rail processing machine tool of the present application, Figure 5 As shown, the X-direction hard rail 113 installed on the side of the workbench mounting portion 11 adjacent to the crossbeam frame 3 is a steel-inserted guide rail. The steel-inserted guide rail uses a commercially available finished product and is fixed to the workbench mounting portion 11 with screws. When processing the flap slide rail, the X-direction hard rail 113 on the side of the workbench mounting portion 11 adjacent to the crossbeam frame 3 is subjected to greater cutting stress due to the cutting stress of the machining tool. The use of a steel-inserted guide rail can improve the wear resistance of the X-direction hard rail 113 and ensure that the machining accuracy of the machine tool remains stable after long-term use.

[0061] As another specific implementation of the titanium alloy flap slide rail processing machine tool of the present application, Figure 5 and Figure 6 As shown, a support wing bottom plate 213 is provided on the support wing 21 on the side of the workbench 2 away from the crossbeam frame 3. The support wing bottom plate 213 is a flat alloy steel bar having the same length as the support wing 21, and the support wing bottom plate 213 is fixed on the lower side of the support wing 21, and the upper side surface of the support wing bottom plate 213 contacts the lower side surface, that is, the bottom surface, of the X-direction hard rail 113, and can slide on the X-direction hard rail 113.

[0062] In some embodiments of the titanium alloy flap slide rail processing machine tool of the present application, as Figure 5 As shown, a chip groove 13 is provided between the workbench mounting portion 11 and the crossbeam mounting portion 12 on the bed 1. The length of the chip groove 13 is the same as that of the workbench mounting portion 11, and the height is slightly lower than the top surface of the workbench mounting portion 11, which is conducive to the chips formed by the flap slide rail processing on the workbench 2 moved to different positions on the workbench mounting portion 11 to slide into the chip groove 13.

[0063] A chip removal mechanism is provided in the chip removal groove 13 , and the chips that slide into the chip removal groove 13 can be removed by the chip removal mechanism, thereby preventing the chips from accumulating in the chip removal groove 13 .

[0064] In some embodiments of the titanium alloy flap slide rail processing machine tool of the present application, as Figure 1As shown, telescopic chip guard covers 114 are provided on both sides of the workbench 2 in the X direction, and the telescopic chip guard covers 114 cover the top surface of the workbench mounting part 11, and the X-axis linear rail 111 and the X-axis driving screw 112 installed on the top surface of the workbench mounting part 11, and the X-axis hard rail 113 on the side of the workbench mounting part 11 are all covered below the telescopic chip guard cover 114.

[0065] One end of the telescopic chip guard cover 114 is fixed on the workbench 2, and the other end is fixed on the bed 1 at the end of the workbench mounting part 11. When the workbench 2 slides on the workbench mounting part 11, the telescopic chip guard cover 114 on one side of the workbench 2 extends, and the telescopic chip guard cover 114 on the other side shortens, ensuring that the telescopic chip guard covers 114 on both sides completely cover the upper structure of the workbench mounting part 11.

[0066] A lifting chip blocking curtain 33 is provided on one side of the crossbeam frame 3 adjacent to the workbench 2, and the lifting chip blocking curtain 33 covers the end of the slide installation space surrounded by the crossbeam 31, two columns 32 and the crossbeam frame mounting portion 12 to prevent cutting chips from entering the slide installation space.

[0067] Generally, the lifting and lowering chip-blocking curtain 33 includes an upper telescopic curtain section, a hard curtain section and a lower telescopic curtain section. A ram passage is provided in the middle of the hard curtain section. One end of the ram 5 passes through the lifting and lowering chip-blocking curtain 33 and extends toward the workbench 2 through the ram passage; the upper end of the upper telescopic curtain section is connected to the crossbeam 31, and the lower end is connected to the hard curtain section; the upper end of the lower telescopic curtain section is connected to the hard curtain section, and the lower end is connected to the crossbeam frame mounting portion 12. When the box-in-box slide plate 4 is lifted and lowered on the crossbeam frame 3, the hard curtain section is lifted and lowered synchronously with the ram 5, and the lifting and lowering chip-blocking curtain 33 is kept to completely cover the end of the slide plate installation space through the extension and retraction of the upper telescopic curtain section and the lower telescopic curtain section.
