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 finishing 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 flap rails are usually fine-machined using a general gantry machine. The gantry of the general gantry machine is usually slidably mounted on the bed and moves in the X direction on the bed; the slide is slidably mounted on the crossbeam of the gantry and moves on the crossbeam in the Y direction; the ram is slidably mounted on the slide and moves on the slide in the Z direction, forming a free sliding of the spindle head mounted on the ram in three-dimensional space. In order to be able to process some large workpieces, the height of the gantry crossbeam of the general gantry machine is usually high. When processing the aircraft flap rails, the distance between the slide and the flap rail is long, which easily forms a large cutting torque on the slide, making it easy for the slide, slide and gantry to produce strain under the action of large cutting stress, resulting in the positional deviation of the spindle head during the cutting process, affecting the fine machining accuracy of the flap rails. In addition, the flap rails of the aircraft are usually made of titanium alloy materials. Compared with steel and aluminum alloy materials, titanium alloy materials have higher hardness and greater cutting stress, making it more difficult to ensure the machining accuracy of the flap rails processed by the general gantry machine. Summary of the invention

[0005] In order to improve the machining accuracy of aircraft flap slide rails, the present application provides a titanium alloy flap slide rail finishing machine tool.

[0006] The titanium alloy flap slide rail finishing machine tool provided in this application adopts the following technical solution: A titanium alloy flap slide finishing machine comprises a bed, a workbench, a beam frame, a slide mechanism and a ram, wherein the workbench is fixedly mounted on one side of the bed, and a first X-direction slide rail and a second X-direction slide rail parallel to each other are arranged on the other side of the bed, the first X-direction slide rail is located on a side of the second X-direction slide rail away from the workbench, and the height of the first X-direction slide rail is higher than the height of the second X-direction slide rail, the beam frame is slidably mounted on the bed via the first X-direction slide rail and the second X-direction slide rail, the slide mechanism is arranged on the inner side of the beam frame and can slide in the Y direction on the inner side of the beam frame, the ram is slidably mounted on the slide mechanism and can slide in the Z direction on the slide mechanism, so that the flap slide mounted on the workbench can be cut by using a spindle head mounted on the ram.

[0007] By adopting the above technical solution, the workbench is installed on one side of the bed and the crossbeam is installed on the other side of the bed, so that the ram and the spindle head installed on the ram can be installed in the crossbeam, and the flap slide rail is horizontally processed from one side of the flap slide rail installed on the workbench, so that the distance between the slide plate mechanism on which the ram is installed and the flap slide rail can be set closer, effectively reducing the cutting torque acting on the ram and the slide plate mechanism during the processing, reducing the strain of the ram and the slide plate mechanism, and improving the position accuracy of the spindle head. By setting the height of the first X-direction slide rail higher than the height of the second X-direction slide rail, the stability of the crossbeam when moving in the X direction under a large cutting stress can be improved, and the position accuracy of the crossbeam and the slide plate mechanism installed on the crossbeam can be improved. By setting the slide plate mechanism installed on the inner side of the crossbeam, the crossbeam can limit the position of the slide plate from both sides of the slide plate mechanism, improve the stability of the position of the slide plate when moving in the Y direction, and ensure the positioning accuracy of the slide plate mechanism, the ram installed on the slide plate mechanism, and the spindle head installed on the ram.

[0008] In a specific feasible implementation scheme, the beam frame includes a beam frame base, a first column, a second column and a beam, the beam frame base is arranged parallel to the first X-axis slide rail and the second X-axis slide rail, and the two sides are respectively installed on the first X-axis slide rail and the second X-axis slide rail, the first column and the second column are respectively fixed at the two ends of the length direction of the beam frame base, and the two ends of the beam are respectively fixed on the first column and the second column, an X-axis driving screw is arranged between the first X-axis slide rail and the second X-axis slide rail on the bed, one end of the X-axis driving screw is connected to the X-axis driving motor arranged on the bed, and the screw nut of the X-axis driving screw is fixedly connected to the beam frame base.

[0009] By adopting the above technical solution, the beam frame base is installed on both sides of the first X-direction slide rail and the second X-direction slide rail, respectively, so as to improve the position stability of the beam frame base when it slides in the X direction on the bed, and improve the position accuracy of the beam frame base under lateral stress. By using the X-direction driving screw rod arranged between the first X-direction slide rail and the second X-direction slide rail on the bed, a stable driving force can be formed to drive the beam frame base to slide on the first X-direction slide rail and the second X-direction slide rail, so as to ensure the position accuracy of the beam frame sliding in the X direction.

The bed hard rail slide bars arranged on the bottom surface of the bed hard rail slide groove can reduce the wear of the bottom surface of the bed hard rail slide groove when the beam frame base slides in the X direction, and better maintain the position accuracy of the beam frame during long-term, high-stress cutting processing.

The slide mechanism includes a first slide, a second slide and a support plate. The first slide is fixed on the slider of the first Y-axis slide rail, the second slide is fixed on the slider of the second Y-axis slide rail and is fixedly connected to the screw nut of the Y-axis driving screw, and the two ends of the support plate are respectively connected to the upper parts of the first slide and the second slide.

[0015] By adopting the above technical solution, with the first slide being fixed on the first Y-direction slide rail slider and the second slide being fixed on the second Y-direction slide rail slider, the sliding positions of the first slide and the second slide can be respectively limited from both sides of the slide mechanism, thereby improving the position stability of the slide mechanism when moving in the Y direction.

[0017] By adopting the above technical scheme, the left and right sides of the slide are respectively connected to the first slide plate through the first Z-direction slide rail, and the second slide plate is connected to the second Z-direction linear rail. Therefore, the position of the slide can be restricted from the left and right sides of the slide, which is beneficial for the slide to resist the cutting stress on the left and right sides when processing the flap slide rail, and improve the position accuracy of the slide in the Z-direction sliding on the slide plate mechanism.

[0018] In a specific feasible implementation scheme, a Z-direction hard rail is arranged on the top surface of the slide, a slide hard rail groove is arranged at the corresponding position of the support plate, Z-direction slide bars are arranged on both sides of the slide hard rail groove, and are slidably connected to the Z-direction hard rail through the Z-direction slide bars.

[0019] By adopting the above technical solution, by utilizing the cooperation between the Z-axis hard rail arranged on the top surface of the slide and the slide hard rail groove arranged on the support plate, the position of the slide can be further restricted from the top of the slide, thereby further improving the rigidity of the slide when subjected to cutting stress and improving the cutting accuracy of the spindle head.

[0021] By adopting the above technical solution and utilizing the setting of the spindle hole in the lower middle part of the slide, the gravity stability of the slide can be improved, and in coordination with the Z-axis hard rail set on the top surface of the slide, the cutting stress of the spindle head set at the bottom of the slide when processing the flap slide rail can be effectively counteracted, thereby improving the processing rigidity of the spindle head.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By arranging the workbench and the crossbeam frame on opposite sides of the same bed, the main spindle head installed transversely on the crossbeam frame can be used to perform horizontal processing on the flap slide rail from the side of the flap slide rail clamped on the workbench, thereby avoiding the limitation of the size of the flap slide rail on the size of the crossbeam frame, so that the crossbeam frame can be installed at a position closer to the workbench, reducing the cutting torque of the main spindle head when cutting the flap slide rail, reducing the strain of the ram and the slide plate mechanism when cutting high-hardness titanium alloy materials, and improving the cutting accuracy of the flap slide rail; 2.

DETAILED DESCRIPTION

[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 finishing machine tool of the present application is as follows: Figure 1 and Figure 2As shown, the machine tool comprises a bed 1, a workbench 2, a crossbeam frame 3, a slide mechanism 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 of the machine tool 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 on the aircraft flap rail can be directly clamped on the workbench 2, or the workpiece to be processed can be clamped on an auxiliary clamping block, and then the auxiliary clamping block is fixed on the workbench 2. The workbench 2 is fixedly installed on one side of the bed 1. Specifically, the workbench 2 can be directly fixed on the bed 1, or a mounting structure for mounting the workbench 2 can be provided on the bed 1, and then the workbench 2 is fixedly installed on the mounting structure.

[0039] A first X-direction slide rail 11 and a second X-direction slide rail 12 are arranged on the bed 1 on a side opposite to the workbench 2. The first X-direction slide rail 11 and the second X-direction slide rail 12 extend along the X-direction on the top surface of the bed and are arranged parallel to each other. The second X-direction slide rail 12 is located near the workbench 2, while the first X-direction slide rail 11 is located away from the workbench 2, and the setting height of the first X-direction slide rail 11 is higher than the setting height of the second X-direction slide rail 12.

[0040] The crossbeam frame 3 is a mounting and positioning structure for mounting and positioning the slide mechanism 4 and limiting the moving track of the slide mechanism 4. The crossbeam frame 3 is usually connected by casting materials to ensure the structural strength of the crossbeam frame 3. The two sides of the bottom of the crossbeam frame 3 are respectively mounted on the first X-direction slide rail 11 and the second X-direction slide rail 12 of the bed 1. The frame of the crossbeam frame 3 is parallel to the length direction of the workbench 2, that is, the X direction, and can move along the first X-direction slide rail 11 and the second X-direction slide rail 12 on the bed 1 in the X direction, so that the spindle head 6 mounted on the crossbeam frame 3 can be used to perform cutting processing on different positions of the workpiece to be processed clamped on the workbench 2 in the X direction. The setting of the first X-direction slide rail 11 higher than the second X-direction slide rail 12 enables the crossbeam frame 3 to resist the greater lateral cutting stress transmitted by the spindle head, thereby improving the position stability and position accuracy of the crossbeam frame 3 under large lateral cutting stress.

[0041] The slide mechanism 4 is a sliding installation mechanism formed by installing and connecting casting materials. A vertically extending sliding connection structure extending in the Y direction is provided on the frame bodies on both sides of the cross beam frame 3. The two sides of the slide mechanism 4 are respectively installed on the frame bodies on both sides of the cross beam frame 3 through the sliding connection structures extending in the Y direction, and can slide in the Y direction in the slide installation space formed between the frame bodies on both sides. The frame bodies on both sides of the cross beam frame 3 can limit the X-direction position of the slide mechanism 4, and improve the position stability and position accuracy of the slide mechanism 4 under the X-direction cutting stress state.

[0042] The ram 5 is a barrel-shaped structure for mounting a spindle head 6 for cutting a workpiece to be processed. A ram mounting structure extending perpendicular to the X direction, that is, the Z direction, is provided on the slide mechanism 4. The ram 5 is mounted on the ram mounting structure of the slide mechanism 4 and can slide on the slide mechanism 4 along the Z direction.

[0043] When machining the flap rail of an aircraft, the flap rail is clamped on the workbench 2. A spindle head 6 for cutting the flap rail is installed on the ram 5, and a relative movement between the spindle head 6 and the flap rail in a three-dimensional space is formed by the X-direction movement of the crossbeam frame 3 on the bed, the Y-direction movement of the slide mechanism 4 in the crossbeam frame 3, and the Z-direction movement of the ram 5 on the slide mechanism 4, so as to cut the flap rail.

[0044] Since the spindle head 6 is placed horizontally and performs horizontal cutting on the flap rail from one side of the flap rail, the chips formed during the processing are conducive to escaping from the flap rail and sliding downward, reducing the pulling and scratching of the chips on the surface of the flap rail, which is conducive to ensuring the surface quality of the flap rail cutting process.

[0045] In some embodiments of the titanium alloy flap slide rail finishing machine tool of the present application, as Figure 1 and Figure 2 As shown, the beam frame 3 includes a beam frame base 31, a first column 32, a second column 33 and a beam 34. The beam frame base 31 is a seat body used to install and position other structures of the beam frame 3, and is also used to form a connection between the beam frame 3 and the bed 1. The length direction of the beam frame base 31 is parallel to the first X-axis slide rail 11 and the second X-axis slide rail 12, and the two sides in the width direction are respectively installed on the first X-axis slide rail 11 and the second X-axis slide rail 12. Due to the high height of the first X-axis slide rail 11 and the second X-axis slide rail 12, the supporting force of the bottom of the beam frame base 31 by the first X-axis slide rail 11 and the second X-axis slide rail 12 acts on an inclined plane inclined in the direction of the workbench 2, so that the beam frame 3 can withstand greater lateral cutting stress from the direction of the workbench 2.

[0046] The first column 32 and the second column 33 are respectively fixed at the two ends of the length direction of the beam frame base 31, and the two ends of the beam 34 are respectively fixed at the top of the first column 32 and the second column 33, forming a rectangular skateboard installation space between the beam frame base 31, the first column 32, the second column 33 and the beam 34.

[0047] An X-direction drive screw 13 is arranged between the first X-direction slide rail 11 and the second X-direction slide rail 12 on the bed 1, and the X-direction drive screw 13 is arranged parallel to the first X-direction slide rail 11 and the second X-direction slide rail 12. The two ends of the X-direction drive screw 13 are rotatably mounted on the bed 1 through a rotating mounting seat, and an X-direction drive motor 131 is arranged on one side of the bed 1 at a position opposite to the end of the X-direction drive screw 13, and the output shaft of the X-direction drive motor 131 is connected to the X-direction drive screw 13 through a reducer. The screw nut of the X-direction drive screw 13 is fixed on the bottom surface of the crossbeam frame base 31, and by controlling the rotation of the X-direction drive motor 131, the X-direction drive screw 13 can be driven to rotate, thereby driving the crossbeam frame base 31 to move on the bed 1 along the first X-direction slide rail 11 and the second X-direction slide rail 12 with the screw nut of the X-direction drive screw 13, thereby forming the X-direction movement of the crossbeam frame 3.

[0048] In a preferred embodiment of the titanium alloy flap slide rail finishing machine tool of the present application, as Figures 1 to 3 As shown, the first X-direction slide rail 11 includes a first X-direction linear rail 111 and a first X-direction hard rail 112, and the second X-direction slide rail 12 includes a second X-direction linear rail 121 and a second X-direction hard rail 122. An X-direction slide rail mounting platform 14 is provided on a side of the bed 1 away from the workbench 2, and the top surface height of the X-direction slide rail mounting platform 14 is higher than the top surface height of the bed 1 at an adjacent part. The first X-direction linear rail 111 is fixed on the top surface of the X-direction slide rail mounting platform 14, and the first X-direction hard rail 112 is provided on the top of the side of the X-direction slide rail mounting platform 14 away from the workbench 2.

[0049] The second X-direction linear rail 121 and the second X-direction hard rail 122 are both arranged on the top surface of the bed 1. The top surface height of the bed 1 on the side where the X-direction slide rail mounting platform 14 is located is usually higher than the top surface height of the adjacent bed 1. A top surface boss parallel to the X-direction is formed on the top surface of the bed 1. The second X-direction hard rail 122 is arranged on the side edge of the top surface boss, and is partially located outside the side edge of the top surface boss. The first X-direction linear rail 111 and the second X-direction linear rail 121 are installed between the first X-direction hard rail 112 and the second X-direction hard rail 122, and are installed at the inner adjacent positions of the first X-direction hard rail 112 and the second X-direction hard rail 122 respectively.

[0050] A plurality of sliders are provided on each of the first X-direction linear rail 111 and the second X-direction linear rail 121. Both sides of the bottom surface of the crossbeam frame base 31 are respectively fixed on the plurality of sliders of the first X-direction linear rail 111 and the second X-direction linear rail 121, and can slide in the X direction on the first X-direction linear rail 111 and the second X-direction linear rail 121 together with the plurality of sliders. A lateral support wing 311 is fixedly provided on both sides of the crossbeam frame base 31, and the lower end of the lateral support wing 311 extends downward to a position lower than the first X-direction hard rail 112 and the second X-direction hard rail 122 respectively. A bed hard rail slide groove 312 is provided on the inner side surface of the lateral support wing 311, that is, on the side surface facing the first X-direction hard rail 112 and the second X-direction hard rail 122 respectively, and the lateral support wing 311 is slidably connected with the first X-direction hard rail 112 and the second X-direction hard rail 122 through the bed hard rail slide groove 312 on each inner side surface.

[0051] A slide bar installation groove is set on the bottom surface of the bed hard rail slide groove 312, that is, on the vertical plane parallel to the sides of the first X-axis hard rail 112 and the second X-axis hard rail 122, and a bed hard rail slide bar 313 is fixedly installed in the slide bar installation groove. The bed hard rail slide bar 313 is usually formed by processing high-hardness wear-resistant alloy material, which can further improve the wear resistance of the bed hard rail slide groove 312 and ensure the position stability and position accuracy of the crossbeam frame base 31 under large lateral stress.

[0052] A bed groove side plate 314 is fixedly arranged on the end face of the lower end of the lateral support wing 311, and the bed groove side plate 314 extends inwardly to below the first X-axis hard rail 112 or the second X-axis hard rail 122, forming a lower side wall plate of the bed hard rail slide groove 312, thereby confining the first X-axis hard rail 112 and the second X-axis hard rail 122 in the corresponding bed hard rail slide groove 312 respectively.
