Description

Technical Field

[0001] This application relates to the field of machine tool manufacturing, and in particular to an installation structure of a Z-axis slide of a gantry machine tool for aerospace equipment processing. In addition, this application also relates to a gantry machine tool for aerospace equipment processing. Background Art

[0002] A gantry machine tool is a high-end processing equipment for large-scale machining. Through a gantry machine tool, the overall machining of large mechanical parts can be carried out, the machining accuracy of large parts can be improved, and an effective guarantee is provided for the manufacturing of large high-precision equipment, especially aerospace equipment.

[0003] In order to improve the machining accuracy of a gantry machine tool, it is first necessary to improve the installation and mating accuracy between its own components. A gantry machine tool usually performs mechanical machining on a product to be machined through a spindle head. The spindle head is usually installed on the Z-axis slide of the gantry machine tool and can perform A-axis movement and C-axis movement on the Z-axis slide. The Z-axis slide is installed on the crossbeam through a crossbeam slide plate assembly. The Z-axis slide can move in the Z direction relative to the crossbeam slide plate assembly, and the crossbeam slide plate assembly can move in the Y direction on the crossbeam, forming the Z-axis movement and Y-axis movement of the spindle head; the crossbeam can move in the X direction on the crossbeam frame, forming the X-axis movement of the spindle head. The movements in multiple axes cooperate with each other to form the multi-axis linkage of the spindle head, effectively improving the machining accuracy of multiple machining surfaces on the workpiece to be machined and the mating accuracy between multiple machining surfaces. Among them, the Z-axis slide not only has a relatively large mass itself, but also bears the A-axis moving parts and C-axis moving parts of the spindle head, further increasing the machining stress borne by the Z-axis slide. Improving the installation and positioning accuracy of the Z-axis slide is particularly important for ensuring the machining accuracy of the spindle head, especially for gantry machine tools used in the processing of aviation and aerospace equipment. Since the machining accuracy required for the processing of aviation and aerospace equipment is higher and the machining speed is faster, this requires the Z-axis slide to have higher installation accuracy and be able to maintain the positioning stability of the Z-axis slide when bearing greater machining stress.

[0004] The Z-axis slide of the existing gantry machine tool for aerospace equipment processing is mainly installed on the crossbeam of the gantry machine tool through the crossbeam slide plate assembly. The installation and positioning accuracy are mainly ensured by the processing and installation accuracy of the crossbeam slide plate assembly. The existing crossbeam slide plate assembly is usually an integral structure. The bottom mounting surface of the crossbeam slide plate assembly is matched with the crossbeam, and the inner mounting surface is matched with the Z-axis slide. In order to ensure the accuracy of the Z-axis movement of the Z-axis slide perpendicular to the horizontal plane, it is not only necessary to ensure the processing accuracy of the bottom mounting surface and the inner mounting surface of the crossbeam slide plate assembly itself, but also to ensure the matching accuracy between the bottom mounting surface and the inner mounting surface, which requires too high processing accuracy for the crossbeam slide plate assembly and greatly increases the processing cost of the crossbeam slide plate assembly. When installing the Z-axis slide, it is usually necessary to use pads with a certain thickness at different positions between the bottom mounting surface of the crossbeam slide plate assembly and the crossbeam to adjust the sliding direction of the Z-axis slide at different angles. Not only is the adjustment process complex and the adjustment accuracy low, but it is also difficult to ensure the position stability of the Z-axis slide during high-intensity processing. Summary of the Invention

[0005] In order to ensure the installation and positioning accuracy of the Z-axis slide of the gantry machine tool for aerospace equipment processing, the present application provides an installation structure for the Z-axis slide of the gantry machine tool for aerospace equipment and a gantry machine tool.

[0006] The installation structure for the Z-axis slide of the gantry machine tool for aerospace equipment provided by the present application adopts the following technical solutions:

[0007] An installation structure for the Z-axis slide of a gantry machine tool for aerospace equipment, comprising a first crossbeam slide plate, a second crossbeam slide plate, a first slide connecting platform and a second slide connecting platform. The first crossbeam slide plate and the second crossbeam slide plate are respectively installed on the two X-axis sides of the crossbeam of the gantry machine tool and can slide in the Y-axis direction on the crossbeam. The first slide connecting platform and the second slide connecting platform are respectively arranged on the two Y-axis sides of the Z-axis slide of the gantry machine tool. The Z-axis slide can move in the Z-axis direction along the first slide connecting platform and the second slide connecting platform. Adjustable connecting pieces are arranged between the two X-axis sides of the first slide connecting platform and the second slide connecting platform and the first crossbeam slide plate and the second crossbeam slide plate, and are respectively connected to the first crossbeam slide plate and the second crossbeam slide plate through the adjustable connecting pieces.

[0008] By adopting the above technical solution, the Y-direction sliding of the first crossbeam slide plate and the second crossbeam slide plate on the crossbeam can form the Y-direction movement of the Z-direction slide; the Z-direction sliding of the Z-direction slide along the first slide plate connecting platform and the second slide plate connecting platform can form the Z-direction movement of the Z-direction slide; by using the adjustable connecting pieces connecting the first slide plate connecting platform and the second slide plate connecting platform to different positions of the first crossbeam slide plate, and the adjustable connecting pieces connecting the first slide plate connecting platform and the second slide plate connecting platform to different positions of the second crossbeam slide plate, the inclination of the Z-direction movement track of the Z-direction slide in the Y-direction can be conveniently adjusted; by using the adjustable connecting pieces on both sides of the first slide plate connecting platform in the X-direction and the adjustable connecting pieces on both sides of the second slide plate connecting platform in the X-direction, the inclination of the Z-direction movement track of the Z-direction slide in the X-direction can be conveniently adjusted. Thus, the Z-direction movement track of the Z-direction slide can be conveniently adjusted by adjusting the adjustable connecting pieces, reducing the processing precision requirements for the first crossbeam slide plate, the second crossbeam slide plate, the first slide plate connecting platform and the second slide plate connecting platform.

[0009] In a specific implementable embodiment, the adjustable connecting piece includes a plurality of connecting platform top blocks, the connecting platform top blocks are respectively arranged on both sides of the first slide plate connecting platform and the second slide plate connecting platform in the X-direction, and are arranged at intervals on both sides of the first crossbeam slide plate in the X-direction and both sides of the second crossbeam slide plate in the X-direction, and support adjusting screw holes are arranged on the connecting platform top blocks.

[0010] By adopting the above technical solution, by using a plurality of connecting platform top blocks arranged on the first slide plate connecting platform and the second slide plate connecting platform, both sides of the first slide plate connecting platform and the second slide plate connecting platform in the X-direction can be respectively supported on the first crossbeam slide plate and the second crossbeam slide plate, forming the support for the Z-direction slide and determining the sliding direction of the Z-direction slide. By using the support adjusting screw holes arranged on the connecting platform top blocks, the support height of different connecting platform top blocks can be adjusted by using the adjusting bolts screwed into the support adjusting screw holes of each connecting platform top block, so as to adjust the inclination angles of different directions of the sliding track of the Z-direction slide.

[0011] In a specific implementable embodiment, the adjustable connecting piece further includes X-direction adjusting screw holes, and the X-direction adjusting screw holes are arranged at positions corresponding to the first slide plate connecting platform on the side walls of the first crossbeam slide plate and the second crossbeam slide plate, and positions corresponding to the second slide plate connecting platform.

[0012] By adopting the above technical solution, the support position of the first slide plate connecting platform and the second slide plate connecting platform in the X-direction can be adjusted by screwing the adjusting screw into the X-direction adjusting screw hole, so as to adjust the position positioning of the Z-direction slide in the X-direction.

[0013] In a specific feasible implementation, injection molding recessed areas are provided at the positions corresponding to the first slide table of the first cross beam slide plate and the second slide table, and at the positions corresponding to the first slide table of the second cross beam slide plate and the second slide table; and / or, injection molding recessed areas are provided on the sides of the first slide table adjacent to the first cross beam slide plate, the sides of the second slide table adjacent to the first cross beam slide plate, the sides of the first slide table adjacent to the second cross beam slide plate, and the sides of the second slide table adjacent to the second cross beam slide plate; injection molding holes communicating with the injection molding recessed areas are provided on the first cross beam slide plate and the second cross beam slide plate.

[0014] By adopting the above technical solution, by using the injection molding recessed areas on the side walls of the first cross beam slide plate, the second cross beam slide plate, and / or the side walls of the first slide table and the second slide table, injection molding plastic can be injected to form fixed connections between the first slide table and the second slide table and the first cross beam slide plate, and between the first slide table and the second slide table and the second cross beam slide plate, improving the positioning stability of the Z-direction slide table and its sliding track during high-intensity processing and under large processing stresses.

[0016] By adopting the above technical solution, by using the cooperation between the top Y-direction slide blocks and the top Y-direction slide rails, stable sliding between the first cross beam slide plate and the second cross beam slide plate and the cross beam can be formed. By controlling the mating surfaces between the first cross beam slide plate and the second cross beam slide plate and the top Y-direction slide blocks, and between the top Y-direction slide rails and the cross beam, it can be ensured that the Z-direction movement track of the Z-direction slide table remains stable during the Y-direction movement and under large processing stresses.

[0018] By adopting the above technical solution, the cooperation between the side Y-direction slider and the side Y-direction slide rail can improve the position stability of the first slide plate connecting platform and the second slide plate connecting platform. Through the control of the mating surfaces between the first slide plate connecting platform and the second slide plate connecting platform and the side Y-direction slider, and the control of the side Y-direction slide rail and the side of the cross beam, the stability of the first slide plate connecting platform and the second slide plate connecting platform during the Y-direction sliding process can be ensured, so that the Z-direction movement trajectory of the Z-direction slide table can remain stable during high-intensity processing.

[0020] By adopting the above technical solution, the cooperation between the Z-direction slider and the Z-direction slide rail can ensure that the Z-direction slide table can slide smoothly along the sides of the first slide plate connecting platform and the second slide plate connecting platform. By controlling the mating surfaces between the first slide plate connecting platform and the second slide plate connecting platform and the Z-direction slide rail, and the mating surfaces between the Z-direction slide table and the Z-direction slide rail, the linearity of the Z-direction movement trajectory of the Z-direction slider during high-intensity processing can be ensured.

[0021] In a specific feasible implementation scheme, a balance cylinder top plate seat is arranged on the top of the Z-direction slide table, a slide table Z-direction driving member is arranged on one side of the Z-direction slide table, and a Z-direction balance cylinder connected to the balance cylinder top plate seat is arranged on the other side. One of the slide table Z-direction driving member and the Z-direction balance cylinder is connected to the first slide plate connecting platform, and the other is connected to the second slide plate connecting platform.

[0022] By adopting the above technical solution, by using the balance cylinder top plate seat and the Z-direction balance cylinder, it can be ensured that under the condition that the slide table Z-direction driving member drives on one side of the Z-direction slide table, the large-mass Z-direction slide table can form a stable Z-direction movement and maintain the stability of the Z-direction movement trajectory.

[0023] In a specific feasible implementation scheme, both the first cross beam slide plate and the second cross beam slide plate are of rectangular groove-shaped structures. The first cross beam slide plate and the second cross beam slide plate are installed on the cross beam through the bottom walls and are connected to the first slide plate connecting platform and the second slide plate connecting platform through the inner side walls.

[0025] The gantry machine tool for aerospace equipment processing provided by this application adopts the Z-axis slide mounting structure of the gantry machine tool for aerospace equipment processing of this application.

[0026] By adopting the above technical solution, the Z-axis slide mounting structure of the gantry machine tool for aerospace equipment processing of this application can conveniently adjust the Z-axis movement trajectory of the Z-axis slide, effectively improve the installation and positioning accuracy and position stability of the Z-axis slide, and reduce the processing accuracy requirements of the installation and positioning structure, thereby reducing the production and manufacturing costs.

[0038] The following will describe in detail the specific embodiments of this application with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of this application, and are not used to limit this application.

[0039] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "set" and "connect" 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, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0040] In this specification, the terms "first" and "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of the above features.

[0041] An embodiment of the Z-axis slide mounting structure of the gantry machine tool for aerospace equipment processing in this application, as Figure 1As shown in the figure, it includes a first crossbeam slide plate 1, a second crossbeam slide plate 2, a first slide plate connecting platform 3 and a second slide plate connecting platform 4. The crossbeam 5 of the gantry machine tool is a hollow box girder. The Z-direction slide 6 is arranged in the hollow space of the crossbeam 5. The first crossbeam slide plate 1 and the second crossbeam slide plate 2 are respectively arranged on the crossbeam 5 on both sides of the Z-direction slide 6, located on the X-direction both sides of the Z-direction slide 6.

[0042] The first slide plate connecting platform 3 and the second slide plate connecting platform 4 are respectively arranged on the Y-direction both sides of the Z-direction slide 6, and the X-direction both sides of the first slide plate connecting platform 3 and the second slide plate connecting platform 4 are respectively located inside the first crossbeam slide plate 1 and the second crossbeam slide plate 2, so that the first crossbeam slide plate 1, the second crossbeam slide plate 2, the first slide plate connecting platform 3 and the second slide plate connecting platform 4 jointly surround the periphery of the Z-direction slide 6, forming positioning and support for the Z-direction slide 6.

[0043] In this application, the X-direction refers to the direction perpendicular to the length direction of the crossbeam 5, that is, the direction in which the crossbeam 5 slides on the two side beds of the gantry machine tool; the Y-direction refers to the length direction of the crossbeam 5. The crossbeam 5 of the gantry machine tool is usually horizontally arranged, that is to say, the X-direction and the Y-direction are two mutually perpendicular directions on the horizontal plane. The Z-direction refers to the vertical direction, that is, the direction perpendicular to the horizontal plane. The Z-direction slide 6 is usually vertically arranged and can perform strict Z-direction movement under ideal conditions.

[0044] Adjustable connecting members 7 are arranged between the first slide plate connecting platform 3 and the first crossbeam slide plate 1 and the second crossbeam slide plate 2, and between the second slide plate connecting platform 4 and the first crossbeam slide plate 1 and the second crossbeam slide plate 2. The adjustable connecting member 7 can be a structural member that can adjust the positional relationship between the slide plate connecting platform and the crossbeam slide plate, such as a threaded connection structural member, a tie rod connection structural member or a wedge block connection structural member, etc. The positional relationship between the first slide plate connecting platform 3 and the second slide plate connecting platform 4 and the first crossbeam slide plate 1 and the second crossbeam slide plate 2 can be respectively adjusted through the adjustable connecting member 7.

[0045] Both the first crossbeam slide plate 1 and the second crossbeam slide plate 2 are slidably connected to the crossbeam 5, so that they can slide along the Y-direction on the crossbeam 5. Specifically, the first crossbeam slide plate 1 and the second crossbeam slide plate 2 can be slidably connected to the crossbeam 5 in various possible ways such as a guide rail and a guide wheel, a slide rail and a slider, a chute and a slider. By improving the flatness and smoothness of the mating surface processing between the first crossbeam slide plate 1 and the second crossbeam slide plate 2 and the crossbeam 5, the sliding of the first crossbeam slide plate 1 and the second crossbeam slide plate 2 on the crossbeam 5 can be made to approach being on the same horizontal plane, and the smoothness of the sliding can be improved.

[0046] The two Y-direction sides of the Z-direction slide 6 are respectively slidably connected to the sides of the first slide connecting platform 3 and the second slide connecting platform 4. Similarly, various possible ways such as guide rails and guide wheels, slide rails and sliders, and slide grooves and sliders can be used for the sliding connection, enabling the Z-direction slide 6 to slide in the Z direction along the sides of the first slide connecting platform 3 and the second slide connecting platform 4. By controlling the flatness and smoothness of the mating surfaces between the Z-direction slide 6 and the first slide connecting platform 3 and the second slide connecting platform 4 during machining, the sliding of the Z-direction slide 6 can be made as much as possible in the vertical direction, and the smoothness of the sliding of the Z-direction slide 6 can be improved.

[0047] However, machining errors inevitably exist in machining, and moreover, high-precision machining will cause a large increase in machining costs. The Z-direction slide 6 of a general gantry machine tool is installed and positioned by using a crossbeam slide plate assembly. The general crossbeam slide plate assembly is an integral component, whose lower side slides in the Y direction on the crossbeam 5, and the Z-direction slide 6 slides on the side of the crossbeam slide plate assembly. In order to ensure the horizontal sliding of the crossbeam slide plate assembly on the crossbeam and the vertical sliding of the Z-direction slide on the crossbeam slide plate, not only the flatness and smoothness of the mating surface between the crossbeam slide plate assembly and the crossbeam 5, and the verticality and smoothness of the mating surface between the crossbeam slide plate assembly and the Z-direction slide 6 are required, but also the perpendicularity between the crossbeam mating surface and the Z-direction slide mating surface on the crossbeam slide plate assembly needs to be ensured. This greatly increases the machining difficulty of the crossbeam slide plate assembly and makes the crossbeam slide plate assembly have a high machining cost. When it is found during the installation process that the lifting trajectory of the Z-direction slide 6 does not meet the designed Z-direction requirements, only by adding adjusting pads with a set thickness and the same machining precision under the lower mating surface of the crossbeam slide plate assembly can the installation heights of different parts of the crossbeam slide plate assembly be adjusted, so as to adjust the deviation of the lifting trajectory of the Z-direction slide 6 from the vertical direction. The adjustment process is complex and the adjustment difficulty is also very large.

[0048] This application adopts a split installation structure composed of a first crossbeam slide plate 1, a second crossbeam slide plate 2, a first slide plate connecting platform 3 and a second slide plate connecting platform 4, and connects the first crossbeam slide plate 1 and the second crossbeam slide plate 2 to the first slide plate connecting platform 3 and the second slide plate connecting platform 4 through adjustable connectors 7. Since the first crossbeam slide plate 1 and the second crossbeam slide plate 2 only need to cooperate with the crossbeam 5, and the first slide plate connecting platform 3 and the second slide plate connecting platform 4 only need to cooperate with the Z-direction slide table, and the first crossbeam slide plate 1, the second crossbeam slide plate 2, the first slide plate connecting platform 3 and the second slide plate connecting platform 4 are processed separately. The position relationship between the first crossbeam slide plate 1 and the second crossbeam slide plate 2 and the first slide plate connecting platform 3 and the second slide plate connecting platform 4 is adjusted through the adjustable connectors 7, so as to ensure that the lifting trajectory of the Z-direction slide table 6 meets the designed Z-direction requirements, greatly reducing the processing difficulty of the Z-direction slide table installation structure. When installing the Z-direction slide table 6, first install the first crossbeam slide plate 1 and the second crossbeam slide plate 2 on the crossbeam 5, install the first slide plate connecting platform 3 and the second slide plate connecting platform 4 on the Z-direction slide table 6, and then connect the first slide plate connecting platform 3 and the second slide plate connecting platform 4 to the first crossbeam slide plate 1 and the second crossbeam slide plate 2 respectively through the adjustable connectors 7. By respectively adjusting the adjustable connectors 7 between the first slide plate connecting platform 3 and the second slide plate connecting platform 4 and the first crossbeam slide plate 1, and respectively adjusting the adjustable connectors 7 between the first slide plate connecting platform 3 and the second slide plate connecting platform 4 and the second crossbeam slide plate 2, the inclination of the Y-direction of the movement trajectory of the Z-direction slide table 6 can be adjusted; by respectively adjusting the adjustable connectors 7 between the first slide plate connecting platform 3 and the first crossbeam slide plate 1 and between the second crossbeam slide plate 2, and respectively adjusting the adjustable connectors 7 between the second slide plate connecting platform 4 and the first crossbeam slide plate 1 and between the second crossbeam slide plate 2, the inclination of the X-direction of the movement trajectory of the Z-direction slide table 6 can be adjusted. By adjusting the inclination of the X-direction and the Y-direction of the movement trajectory of the Z-direction slide table 6, the movement trajectory of the Z-direction slide table 6 can be reliably ensured to meet the designed Z-direction requirements.

[0049] In some embodiments of the Z-direction slide table installation structure of the gantry machine tool for aerospace equipment processing in this application, as Figure 1 shown, multiple connecting platform top blocks 71 are used as an adjustable connector 7. The connecting platform top block 71 can usually use a square metal block, and through fixing screw holes are provided on a set of side surfaces of the connecting top block 71, and through support adjustment screw holes 711 are provided on the upper and lower opposite surfaces.

[0050] Use fixed bolts to pass through the fixed screw holes on the connecting top block 71 to fix two connecting table top blocks 71 at intervals on the side surface of the first slide table connecting platform 3 connected to the first cross beam slide 1. Use the same method to fix two connecting table top blocks 71 at intervals on the side surface of the first slide table connecting platform 3 connected to the second cross beam slide 2, on the side surface of the second slide table connecting platform 4 connected to the first cross beam slide 1, and on the side surface of the second slide table connecting platform 4 connected to the second cross beam slide 2. Install the first slide table connecting platform 3 and the second slide table connecting platform 4 respectively between the X-direction two sides of the first cross beam slide 1 and the second cross beam slide 2, so that each connecting table top block 71 is located on the first cross beam slide 1 or the second cross beam slide 2, and the support adjustment screw hole 711 corresponds to the upper side surface of the first cross beam slide 1 or the second cross beam slide 2. Support the first slide table connecting platform 3 and the second slide table connecting platform 4 on the first cross beam slide 1 and the second cross beam slide 2 through the connecting table top blocks 71.

[0051] Screw an adjusting nut into the support adjustment screw hole 711 so that the end of the adjusting nut supports on the upper side surface of the first cross beam slide 1 or the second cross beam slide 2. In this way, by rotating the adjusting nuts on different connecting table top blocks 71, it is possible to conveniently adjust the support height of the first slide table connecting platform 3 and the second slide table connecting platform 4 on the first cross beam slide 1 and the second cross beam slide 2, thereby adjusting the inclination of the lifting trajectory of the Z-direction slide 6 in different directions, so that the lifting trajectory of the Z-direction slide 6 meets the designed Z-direction requirements.

[0052] In a preferred embodiment of the Z-direction slide mounting structure of the gantry machine tool for aerospace equipment processing in the present application, as Figure 1 and Figure 2 shown, the adjustable connecting member 7 further includes X-direction adjustment screw holes 72 provided on the side walls of the first cross beam slide 1 and the second cross beam slide 2. At the positions on the side wall of the first cross beam slide 1 corresponding to the first slide table connecting platform 3, at the positions on the side wall of the first cross beam slide 1 corresponding to the second slide table connecting platform 4, at the positions on the side wall of the second cross beam slide 2 corresponding to the first slide table connecting platform 3, and at the positions on the side wall of the second cross beam slide 2 corresponding to the second slide table connecting platform 4, a plurality of X-direction adjustment screw holes 72 are provided. Screw an adjustment bolt into the X-direction adjustment screw hole 72 so that the top ends of the adjustment bolts respectively abut against the first slide table connecting platform 3 and the second slide table connecting platform 4. By adjusting the adjustment bolts in the X-direction adjustment screw holes at different positions, it is possible to respectively adjust the connection gaps between the first slide table connecting platform 3 and the second slide table connecting platform 4 and the first cross beam slide 1 and the second cross beam slide 2, thereby adjusting the position positioning of the Z-direction slide 6.

[0053] As a specific implementation manner of the Z-direction slide mounting structure of the gantry machine tool for aerospace equipment processing in the present application, as Figure 2 and Figure 3As shown, at least one of the positions corresponding to the side wall of the first crossbeam slide 1 and the first slide connecting platform 3, and the positions corresponding to the side wall of the first slide connecting platform 3 and the first crossbeam slide 1 is provided with an injection molding recessed area 73. Similarly, at least one of the positions corresponding to the side wall of the second crossbeam slide 2 and the first slide connecting platform 3, and the positions corresponding to the side wall of the first slide connecting platform 3 and the second crossbeam slide 2 is provided with an injection molding recessed area 73; at least one of the positions corresponding to the side wall of the first crossbeam slide 1 and the second slide connecting platform 4, and the positions corresponding to the side wall of the second slide connecting platform 4 and the first crossbeam slide 1 is provided with an injection molding recessed area 73; at least one of the positions corresponding to the side wall of the second crossbeam slide 2 and the second slide connecting platform 4, and the positions corresponding to the side wall of the second slide connecting platform 4 and the second crossbeam slide 2 is provided with an injection molding recessed area 73.

[0054] The injection molding recessed area 73 is formed as an injection cavity between the first crossbeam slide 1 and the first slide connecting platform 3, between the first crossbeam slide 1 and the second slide connecting platform 4, between the second crossbeam slide 2 and the first slide connecting platform 3, and between the second crossbeam slide 2 and the second slide connecting platform 4. After the adjustment of the adjustable connecting member 7 is completed and the lifting trajectory of the Z-direction slide 6 has reached the designed Z-direction requirements, injection plastic is injected into the injection molding recessed area 73, and the injection plastic solidifies to form a fixed connection between the first crossbeam slide 1 and the first slide connecting platform 3 and the second slide connecting platform 4, and between the second crossbeam slide 2 and the first slide connecting platform 3 and the second slide connecting platform 4, which can prevent the offset of the positional relationship between the first crossbeam slide 1, the second crossbeam slide 2, the first slide connecting platform 3, and the second slide connecting platform 4, and ensure the stability of the movement trajectory of the Z-direction slide 6.

[0055] At the positions corresponding to the injection molding recessed area 73 on the first crossbeam slide 1 and the second crossbeam slide 2, injection holes 74 communicating with the injection molding recessed area 73 are provided. After the adjustment of the adjustable connecting member 7 is completed, sealing tapes are pasted at the gaps between the crossbeam slides and the slide connecting platforms around the injection molding recessed area 73, and then injection plastic can be injected into the injection molding recessed area 73 through the injection holes 74. Usually, two injection holes 74 are provided at the positions corresponding to the same injection molding recessed area 73. One injection hole 74 is provided at the corresponding position at the top of the injection molding recessed area 73, and the other injection hole 74 is provided at a slightly lower position away from the first injection hole 74. The injection plastic is injected through the injection hole 74 with a lower position, and the air in the injection molding recessed area 73 escapes from the injection hole 74 with a higher position, so that the injection plastic fills the injection molding recessed area 73. When the injection plastic flows out of the injection hole 74 with a higher position, the injection stops, and the two injection holes 74 are closed, waiting for the injection plastic to solidify.

[0056] In some embodiments of the Z-direction slide mounting structure of the gantry machine tool for aerospace equipment processing in the present application, such as Figure 1As shown in the figure, a top Y-direction slide rail 51 is provided on each side of the cross beam 5 in the X direction. The two top Y-direction slide rails 51 are respectively arranged on the cross beam 5 on both sides of the Z-direction slide table 6 in the X direction and are arranged along the Y direction on the cross beam 5. A plurality of top Y-direction slide blocks 52 are arranged on each top Y-direction slide rail 51. For example, 3 top Y-direction slide blocks 52 are arranged. The top Y-direction slide blocks 52 are in precise fit with the top Y-direction slide rails 51. The lower mating surfaces of the first cross beam slide plate 1 and the second cross beam slide plate 2 are fixedly connected to the top Y-direction slide blocks 52. In this way, the first cross beam slide plate 1 and the second cross beam slide plate 2 can slide in the Y direction on the cross beam 5 through the sliding of the top Y-direction slide blocks 52 on the top Y-direction slide rails 51. The accuracy of the sliding track and the smoothness of the sliding are mainly determined by the matching accuracy between the top Y-direction slide blocks 52 and the top Y-direction slide rails 51, further reducing the processing accuracy requirements for the first cross beam slide plate 1 and the second cross beam slide plate 2. The arrangement of a plurality of top Y-direction slide blocks 52 can improve the position stability of the first cross beam slide plate 1 and the second cross beam slide plate 2 on the top Y-direction slide rails 51 and reduce the pressure borne by each top Y-direction slide block 52.

[0057] In a preferred embodiment of the Z-direction slide table installation structure of the gantry machine tool for aerospace equipment processing in the present application, as Figure 1 shown, a side Y-direction slide rail 53 is provided at the lower part of the inner side of the hollow area of the box girder of the cross beam 5. A side Y-direction slide rail 53 is provided on the inner side wall of the hollow area of the cross beam 5 on both sides of the Z-direction slide table 6. The side Y-direction slide rail 53 is horizontally arranged along the Y direction. A plurality of side Y-direction slide blocks 54 are arranged on each side Y-direction slide rail 53, and the plurality of side Y-direction slide blocks 54 can all slide on the corresponding side Y-direction slide rails 53. The two sides in the X direction at the lower part of the first slide plate connecting platform 3 and the second slide plate connecting platform 4 are respectively fixedly connected to the side Y-direction slide blocks 54 on the corresponding side Y-direction slide rails 53. Usually, each side of the first slide plate connecting platform 3 and the second slide plate connecting platform 4 is connected to at least two side Y-direction slide blocks 54. The arrangement of the side Y-direction slide rail 53 and the side Y-direction slide blocks 54 further improves the position stability of the combination of the first cross beam slide plate 1, the second cross beam slide plate 2, the first slide plate connecting platform 3 and the second slide plate connecting platform 4 and the sliding stability on the cross beam 5.

[0058] In some embodiments of the Z-direction slide table installation structure of the gantry machine tool for aerospace equipment processing in the present application, as Figure 1 and Figure 4As shown in the figure, Z-direction slide rails 61 are arranged on both Y-direction sides of the Z-direction slide table 6. The Z-direction slide rails 61 are arranged vertically at the edge parts of the side surfaces on both Y-direction sides of the Z-direction slide table 6. At least two Z-direction sliders 62 are arranged on each Z-direction slide rail 61, and the Z-direction sliders 62 can slide smoothly on the Z-direction slide rails 61. One side of the first slide plate connecting table 3 and the second slide plate connecting table 4 adjacent to the Z-direction slide table 6 is fixedly connected to the Z-direction sliders 62. Specifically, the first slide plate connecting table 3 and the second slide plate connecting table 4 can be directly fixed on the Z-direction sliders 62, or the Z-direction sliders 62 can be first fixed at the corresponding positions on the first slide plate connecting table 3 and the second slide plate connecting table 4, and then the Z-direction sliders 62 are installed on the Z-direction slide rails 61. In this way, by controlling the matching accuracy between the Z-direction slide rails 61 and the Z-direction sliders 62, the accuracy of the lifting trajectory of the Z-direction slide table 6 can be controlled, and the requirement for the machining accuracy of the first slide plate connecting table 3 and the second slide plate connecting table 4 is further reduced.

[0059] In a preferred embodiment of the Z-direction slide table installation structure of the gantry machine tool for aerospace equipment processing in the present application, as Figure 1 and Figure 4 shown, a balance cylinder top plate seat 63 is fixedly connected to the top of the Z-direction slide table 6. A slide table Z-direction driving member 64 is arranged between one side of the Z-direction slide table 6 and the first slide plate connecting table 3 or the second slide plate connecting table 4. The Z-direction slide table 6 can be driven to perform Z-direction lifting movement through the slide table Z-direction driving member 64; a Z-direction balance cylinder 65 is arranged between the other side of the Z-direction slide table 6 and the second slide plate connecting table 4 or the first slide plate connecting table 3. The Z-direction balance cylinder 65 is connected between the balance cylinder top plate seat 63 and the second slide plate connecting table 4 or the first slide plate connecting table 3. When the slide table Z-direction driving member 64 drives the Z-direction slide table 6 to lift on one side of the Z-direction slide table 6, the Z-direction balance cylinder 65 can form a balanced lifting force on the other side of the Z-direction slide table 6 to ensure the stable lifting of the Z-direction slide table 6.

[0060] In some embodiments of the Z-direction slide table installation structure of the gantry machine tool for aerospace equipment processing in the present application, as Figure 1 and Figure 2 shown, both the first crossbeam slide plate 1 and the second crossbeam slide plate 2 are rectangular groove-shaped structures. Specifically, the first crossbeam slide plate 1 and the second crossbeam slide plate 2 can be set as rectangular groove structures with a rectangular bottom plate and four side plates and an open top surface. The rectangular bottom plates of the first crossbeam slide plate 1 and the second crossbeam slide plate 2 are slidably connected to the crossbeam 6 through sliding connection members, and the side plates of the first crossbeam slide plate 1 and the second crossbeam slide plate 2 close to the Z-direction slide table 6 are connected to the first slide plate connecting table 3 and the second slide plate connecting table 4 through adjustable connection members 7. Other necessary accessory structures can also be arranged on the first crossbeam slide plate 1 and the second crossbeam slide plate 2. The first crossbeam slide plate 1 and the second crossbeam slide plate 2 with a groove-shaped structure have the advantages of light weight and high mechanical strength.
