Abstract

Disclosed are a manufacturing method for a vehicle contour frame, a frame structure and a vehicle shell. First support beams (1) and second support beams (2) provided with notches are constructed first, and the first support beams (1) and the second support beams (2) are then inserted by means of the corresponding notches to form a cross fixing structure; and cross points of the first support beams (1) and the second support beams (2) are then welded to form an integrated structure. According to the manufacturing method for a vehicle contour frame, a notch structure is provided at the cross point where the support beams cross each other, so that the two beams are correspondingly inserted into one another, thereby ensuring the integrity of the support beams in two directions. The design of the notch size needs to ensure that the outer edges of all the support beams are aligned, in a fitting manner, with the notches after insertion so as to form a desired steel structure contour, thereby providing a frame support for a subsequent exterior panel. By means of the notch structure, the number of assembling beams can be substantially reduced, and the support beams can be assembled quickly and accurately, so that the support beams can form a desired external shape, and this is especially suitable for the streamlined contour of a vehicle body.

现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本发明将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete, and the concept of the example embodiments will be fully conveyed To those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.
本发明实施方式中提供了一种车辆外形骨架制造方法，外形骨架结构是指通过杆件、板件等组成支撑车辆外形的结构，该车辆可以是各种现代轨道车辆，例如，轨道用机车、客货车、有轨车、高度列车、低速列车等。其外形可以指车头，也可以指车尾、车身、车顶或车底等任何部位的外形。该骨架可以是任何可用作车辆骨架的材料，如合金材料、钢材、碳纤维增强复合材料等等，在此不再一一列举。An embodiment of the present invention provides a method for manufacturing a vehicle outer frame. The outer frame structure refers to a structure that supports the outer shape of a vehicle by levers, plates, and the like. The vehicle may be various modern rail vehicles, such as railroad locomotives, Vans, rail cars, high-speed trains, low-speed trains, etc. Its shape can refer to the shape of the car's front, any part of the rear, body, roof or bottom. The skeleton can be any material that can be used as a vehicle skeleton, such as alloy materials, steel, carbon fiber reinforced composite materials, and the like, which are not listed here one by one.
参考图2，本发明实施方式的车辆外形骨架制造方法包括：Referring to FIG. 2, a method for manufacturing a vehicle outline skeleton according to an embodiment of the present invention includes:
步骤S110，成型带有第一插口的第一支撑梁，所述第一支撑梁沿第一方向延伸；Step S110, forming a first support beam with a first socket, the first support beam extending in a first direction;
成型带有第二插口的第二支撑梁，所述第二支撑梁沿第二方向延伸，所述第二方向与所述第一方向不同；Forming a second support beam with a second socket, the second support beam extending in a second direction, the second direction being different from the first direction;
步骤S120，将所述第一插口与所述第二插口插接，以使所述第一支撑梁和第二支撑梁交叉；Step S120: plug the first socket and the second socket so that the first support beam and the second support beam cross;
步骤S130，将所述第一支撑梁和第二支撑梁的交叉点焊接为一体结构。Step S130: welding the intersection of the first support beam and the second support beam into an integrated structure.
通过该方法，在相互交叉的支撑梁交叉点处设置插口结构，使两个梁互相对应***，进行定位，再将交叉点焊接为一体，可以快捷准确地形成骨架结构。With this method, a socket structure is provided at the crossing point of the supporting beams that cross each other, the two beams are inserted correspondingly to each other for positioning, and then the crossing points are welded together to form a skeleton structure quickly and accurately.
该方法尤其适用于流线型外形骨架的搭建，由于传统骨架需要通过多个割断的小梁组装，一旦小梁之间定位不准确，就会影响骨架整体结构的稳定性和强度，本发明的方法不需要打断支撑梁，在设计之初可一次形成所需形状及尺寸精度，无需考虑拼接的问题，解决了小梁之间难以准确定位且尺寸不一致的难题。另外，该方法搭建的支撑梁依然能够保 留足够的强度和刚度，提供足够的安全保障。This method is particularly suitable for the construction of streamlined shape skeletons. Because the traditional skeletons need to be assembled by multiple cut-off trabeculars, once the positioning between the trabeculars is inaccurate, it will affect the stability and strength of the overall structure of the skeleton. The support beam needs to be interrupted, and the required shape and dimensional accuracy can be formed at the beginning of the design, without the need to consider the problem of splicing, and it solves the problems of difficult to accurately position the small beams and the inconsistent dimensions. In addition, the support beam constructed by this method can still retain sufficient strength and rigidity, and provide sufficient safety protection.
下面对本发明实施方式的车辆外形骨架结构进行详细说明：The following describes the vehicle outline structure of the embodiment of the present invention in detail:
步骤S110中，根据车体不同部位的形状，第一支撑梁1和第二支撑梁可以是不同的形状。例如，在车身两侧，第一支撑梁和第二支撑梁可以均为直梁；在车顶，第一支撑梁可以为直梁，第二支撑梁可以为带弧度的曲梁；而在车头，第一支撑梁和第二支撑梁可以均为曲梁。为了保证结构的受力符合要求，该直梁和曲梁优选平面直梁和平面曲梁。In step S110, the first support beam 1 and the second support beam may have different shapes according to the shapes of different parts of the vehicle body. For example, on both sides of the vehicle body, the first support beam and the second support beam can both be straight beams; on the roof, the first support beam can be a straight beam, and the second support beam can be a curved beam with an arc; Both the first support beam and the second support beam may be curved beams. In order to ensure that the stress of the structure meets the requirements, the straight beam and curved beam are preferably planar straight beam and planar curved beam.
在本示例性实施方式中，第一支撑梁的数量设置为多个，且沿第二方向间隔分布，每个第一支撑梁设置多个第一插口，各第一插口排列成多行；第二支撑梁的数量设置为多个，且沿第一方向间隔分布，每个第二支撑梁设置多个第二插口；将任一第二插口与同一行的各第一插口一一对应插接，以使第一支撑梁和第二支撑梁交叉。In this exemplary embodiment, the number of the first support beams is set to be plural and spaced along the second direction. Each first support beam is provided with a plurality of first sockets, and each first socket is arranged in multiple rows. The number of the two supporting beams is set to be multiple, and they are spaced along the first direction. Each second supporting beam is provided with a plurality of second sockets; one of the second sockets is correspondingly connected to each of the first sockets in the same row. So that the first support beam and the second support beam cross.
举例而言，参考图3，为轨道高速列车的车头，图4为车头顶部支撑梁结构，多个第一支撑梁1为平面直梁(图中横梁)，相互平行排列，多个第二支撑梁2包括位于中间的平面直梁和两边的平面曲梁(图中纵梁)，相互平行排列，二者均为截面为矩形的板状结构，横梁下边缘间隔开设有向上的第一插口11，纵梁上边缘间隔开设有向下的第二插口22，由于横梁和纵梁的截面为矩形，所以插口的形状也为矩形，横梁和纵梁的插口相互匹配，使得二者可以相互***形成交叉结构。For example, referring to FIG. 3, the front of a rail high-speed train, FIG. 4 is the top support beam structure of the head, multiple first support beams 1 are flat straight beams (transverse beams in the figure), arranged in parallel with each other, and multiple second supports The beam 2 includes a flat straight beam in the middle and a flat curved beam (longitudinal beam in the figure) on both sides, which are arranged parallel to each other. Both of them are rectangular plate-shaped structures. The lower edge of the beam is provided with an upward first socket 11 at intervals. The upper edge of the longitudinal beam is provided with a second downward socket 22 spaced apart. Since the cross section of the beam and the longitudinal beam is rectangular, the shape of the socket is also rectangular. The sockets of the beam and the longitudinal beam are matched with each other so that the two can be inserted into each other. Cross structure.
当然，本领域技术人员能够理解的是，第一支撑梁1和第二支撑梁2可以互换，即第一支撑梁也可以为图中纵梁，第二支撑梁为图中横梁。Of course, those skilled in the art can understand that the first support beam 1 and the second support beam 2 are interchangeable, that is, the first support beam may also be a longitudinal beam in the figure, and the second support beam is a transverse beam in the figure.
在本示例性实施方式中，由于第一支撑梁1和第二支撑梁2均为截面为矩形板状，因此第一插口11和第二插口22的形状也都为矩形；第一支撑梁1和第二支撑梁2的截面形状除了矩形，也可以是其它多边形、圆形或不规则封闭图形，本发明不对此进行限定。当然，本领域技术人员可以理解的是，如果支撑梁截面为其他形状，其插口的形状也随之变化，只要使得两个支撑梁能够相互***即可。In this exemplary embodiment, since the first support beam 1 and the second support beam 2 are both rectangular plate-shaped in cross section, the shapes of the first socket 11 and the second socket 22 are also rectangular; the first support beam 1 In addition to the rectangular shape, the cross-sectional shape of the second support beam 2 may be other polygons, circles, or irregular closed figures, which is not limited in the present invention. Of course, those skilled in the art can understand that if the cross section of the support beam is other shapes, the shape of the socket will change accordingly, as long as the two support beams can be inserted into each other.
本示例中，参考图4、5，第二支撑梁2上的各插口方向可以不同或成一定角度，第一支撑梁1上的插口方向必须平行，以保证第一支撑梁1上各插口同时***第二支撑梁2对应插口，插口之间不发生相互干涉。In this example, referring to FIGS. 4 and 5, the directions of the sockets on the second support beam 2 may be different or at an angle, and the directions of the sockets on the first support beam 1 must be parallel to ensure that the sockets on the first support beam 1 are simultaneously The corresponding sockets of the second support beam 2 are inserted, and the sockets do not interfere with each other.
另外，在本示例性实施方式中，第一插口11和第二插口22的方向均垂直于各自所在的支撑梁边缘。采用垂直***设计，第一支撑梁1和第二支撑梁2之间不会给对方其他方向的力，使骨架结构更稳定。In addition, in the present exemplary embodiment, the directions of the first socket 11 and the second socket 22 are each perpendicular to the edge of the support beam where they are located. The vertical insertion design is adopted, and the other support force between the first support beam 1 and the second support beam 2 will not be given to each other, so that the skeleton structure is more stable.
支撑梁上的插口可以在梁体加工完毕后再进行加工，也可以和梁体一步加工。The socket on the support beam can be processed after the beam body is processed, or it can be processed in one step with the beam body.
在本示例性实施方式中，为了实现支撑梁的准确、快速成型，步骤S110可以包括以下步骤，In this exemplary embodiment, in order to achieve accurate and rapid forming of the support beam, step S110 may include the following steps,
步骤S111，通过三维造型软件设计并生成带有所述插口的支撑梁三维模型；Step S111: design and generate a three-dimensional model of the supporting beam with the socket by using three-dimensional modeling software;
步骤S112，根据支撑梁三维模型，利用机械设备加工出支撑梁。In step S112, according to the three-dimensional model of the supporting beam, the supporting beam is processed by using mechanical equipment.
通过三维设计软件直接设计好带有插口的支撑梁，再通过切割设备一步成型，既能达 到高精度尺寸和准确定位的要求，又能够快速加工出梁体，提高构建效率。The support beam with the socket is directly designed through the 3D design software, and then formed by the cutting equipment in one step, which can meet the requirements of high-precision size and accurate positioning, and can quickly process the beam body to improve construction efficiency.
步骤S111可以具体按照以下方式实施：Step S111 may be specifically implemented in the following manner:
(1)，以图4车头结构为例，应用三维造型软件生成车头的三维模型，然后根据结构要求在需要布置支撑梁的位置，按一定的间距，以XY、YZ、ZX三个相互垂直的坐标面为基面，进行平行间距切割。如此可得到三维模型外表面在XY、YZ、ZX三个平面的形状曲线，这些形状曲线构成的空间网格构成三维模型的外部形状。然后以获得的形状曲线为平面自由曲线，以形状曲线为基础，赋以宽度和厚度，生成支撑梁的三维模型。(1) Take the front structure of Figure 4 as an example, apply the 3D modeling software to generate a three-dimensional model of the front of the vehicle, and then arrange the support beams at the positions that need to be structured according to the structural requirements. The coordinate plane is the base plane and is cut in parallel. In this way, shape curves of the outer surface of the three-dimensional model in the three planes of XY, YZ, and ZX can be obtained, and the spatial grid formed by these shape curves constitutes the external shape of the three-dimensional model. The obtained shape curve is a plane free curve. Based on the shape curve, the width and thickness are given to generate a three-dimensional model of the supporting beam.
(2)，在相互交叉的支撑梁三维模型之间进行插口设计，根据支撑梁的具体布置和装配顺序，考虑插口的方向、深度和宽度，以使相互交叉的两梁的插口互补。(2) Design the sockets between the three-dimensional models of the supporting beams crossing each other. According to the specific arrangement and assembly sequence of the supporting beams, consider the direction, depth and width of the sockets so that the sockets of the two beams crossing each other are complementary.
(3)，把带有插口尺寸的支撑梁三维模型生成CAD图或dxf文件，利用数控切割设备切割出支撑。(3) Generate a CAD drawing or dxf file of the three-dimensional model of the support beam with the size of the socket, and use the CNC cutting equipment to cut the support.
步骤S112中，利用机械设备加工出支撑梁可以是任何机械方式进行加工，例如铸造、切削等，为了能够精准控制加工精度，提高加工效率，本发明优选数控切割设备。In step S112, the supporting beam processed by mechanical equipment may be processed by any mechanical method, such as casting, cutting, etc. In order to accurately control the processing accuracy and improve the processing efficiency, the present invention is preferably a numerically controlled cutting device.
在本示例性实施方式中，考虑到骨架结构后期蒙皮工艺，在第一支撑梁1和第二支撑梁2进行插***叉时，需要保证交叉固定结构面向车体外侧的边缘平齐。以图4为例，横梁和纵梁的上下插口对应交叉后，二者上边缘在一个平面上，有利于后期蒙皮，保证车体外形的曲面结构。In this exemplary embodiment, in consideration of the later skinning process of the skeleton structure, when the first support beam 1 and the second support beam 2 intersect with each other, it is necessary to ensure that the edges of the cross-fixing structure facing the outside of the vehicle body are flush. Taking Figure 4 as an example, after the upper and lower sockets of the crossbeam and stringer cross correspondingly, the upper edges of the two are on a plane, which is conducive to the later skinning and ensures the curved structure of the shape of the car body.
为了进一步优化整体结构，在本示例性实施方式中，第一支撑梁1和第二支撑梁2的高度相等时，作为最佳实施方案，第一插口11和第二插口22的深度相等，且为第一支撑梁1或第二支撑梁2的高度的一半。按照该结构进行交叉后，二者上、下边缘都在一个平面上，除了保证车体外形的曲面结构，还可以保证内侧的曲面结构。同时，此时两个梁体交叉面积最大，稳定性、刚度和强度最好，整个骨架结构规整，便于设计加工。In order to further optimize the overall structure, in this exemplary embodiment, when the heights of the first support beam 1 and the second support beam 2 are equal, as a best embodiment, the depths of the first socket 11 and the second socket 22 are equal, and It is half the height of the first support beam 1 or the second support beam 2. After crossing according to this structure, the upper and lower edges of the two are on the same plane. In addition to ensuring the curved structure of the car body, the inner curved structure can also be guaranteed. At the same time, the cross-section area of the two beams is the largest at this time, and the stability, stiffness and strength are the best. The whole skeleton structure is regular and easy to design and process.
在本发明其他示例性实施方式中，若第一支撑梁1和第二支撑梁2的高度不等，考虑到整体结构的稳定，第一插口11的深度需小于第一支撑梁高度1的2/3，第二插口22的深度需小于第二支撑梁2高度的2/3。若插口深度过深，支撑梁容易在较大外力冲击下断裂，失去骨架结构的强度In other exemplary embodiments of the present invention, if the heights of the first support beam 1 and the second support beam 2 are different, considering the stability of the overall structure, the depth of the first socket 11 needs to be less than 2 times the height of the first support beam 1. / 3, the depth of the second socket 22 needs to be less than 2/3 of the height of the second support beam 2. If the depth of the socket is too deep, the supporting beam is easily broken under the impact of a large external force, and the strength of the skeleton structure is lost.
步骤S120中，将第一支撑梁1和第二支撑梁2通过第一插口11和第二插口22的对应***形成交叉固定结构时，可以是相互垂直交叉，也可以根据结构需要以其它角度交叉。例如，参考图4，该车头外形为流线型，其骨架结构由相互垂直的第一支撑梁1和第二支撑梁2交叉组成，采用垂直交叉结构，横纵梁之间结构更稳固，且易于加工。In step S120, when the first support beam 1 and the second support beam 2 are inserted through the corresponding insertion of the first socket 11 and the second socket 22 to form a cross-fixing structure, the cross-fixing structure may be perpendicular to each other, or may be intersected at other angles according to the structural requirements. . For example, referring to FIG. 4, the shape of the front of the car is streamlined, and its skeleton structure is composed of the first support beam 1 and the second support beam 2 perpendicular to each other. The vertical cross structure is adopted, and the structure between the transverse and longitudinal beams is more stable and easy to process. .
本示例性实施方式中，组装时，横梁由上至下，使第一插口11***第二插口22，完成横纵梁的组装。为了配合横梁，纵梁弯曲部分的插口方向始终朝向横梁***部分。In the present exemplary embodiment, when assembling, the beam is made from top to bottom, and the first socket 11 is inserted into the second socket 22 to complete the assembly of the transverse and longitudinal beam. In order to fit the cross beam, the direction of the socket of the bent portion of the longitudinal beam always faces the cross beam insertion portion.
为了使第一支撑梁1和第二支撑梁2能够顺利***，考虑组对误差，第一插口和第二插口的宽度应当略大于相应的第二支撑梁和第一支撑梁梁体厚度。通常插口宽度为对应梁体厚度+1mm，左右各留出0.5mm的误差空间。若插口宽度过大，交叉位置焊接点内部空 隙过大，结构不稳定，若插口宽度过小，两个梁体不方便相互***。另外，插口实际加工深度为比设计深度深0.5mm，可在深度方向上留出误差空间，以更好的使两支撑梁交叉匹配。In order to allow the first support beam 1 and the second support beam 2 to be smoothly inserted, and considering the pairing error, the width of the first socket and the second socket should be slightly larger than the thickness of the corresponding second and first support beams. Generally, the width of the socket is + 1mm corresponding to the thickness of the beam body, and an error space of 0.5mm is left and right. If the width of the socket is too large, the internal gap of the welding point at the crossing position is too large, and the structure is unstable. If the width of the socket is too small, the two beam bodies are not convenient to insert into each other. In addition, the actual machining depth of the socket is 0.5mm deeper than the designed depth, which can leave an error space in the depth direction to better match the two supporting beams.
步骤S130中，将所有交叉点处插口焊接为一整体，消除内部空隙，使其成为一个整体结构，即可完成车头外形骨架的构建，参照图6。In step S130, the sockets at all intersections are welded as a whole to eliminate internal voids and make it a whole structure, and then the construction of the front frame can be completed, as shown in FIG.
